DEVICE FOR INSTALLING AND FIXING TOOLS OR CONTRIVANCE

TO VARIOUS  BEARING SURFACES DURING FINISHING

AND CONSTRUCTION WORKS

Field of Invention



     This invention refers to devices that are used to install, adjust and fix tools and contrivances and can be used in various technical fields, particularly, in the construction during plastering, painting, decorating and tiling works, for the  installation and fixation of plaster straightedges, perforated metal strips, scrids, rods, formwork, painting angle irons, window sills as well as during the installation and fixation of in-built safes and cabinets and for the  installation and fixation of different types of building decoration, etc.



Background  Art


     Monitoring performance of modern finishing and painting works in construction, analyzing the quality of work performed by masons, plasterers, tillers, painters and reviewing issues arising at various stages of construction and finishing works, elucidating causes of deficiencies and excessive consumption of primary materials has set the target of making some processes in construction and finishing works less laborious, simpler and safer.

     Presently, during plastering of walls and levelling off plaster planes various handy tools and contrivances, particularly those which  provide the fixation of  reference frames and pilot guides. In particular, these are nails, dowels, crooked nails, spacer strips and self-tapping screws. However, using the above items to fix tools and contrivances is associated with some limitations and drawbacks.

     Fixation of reference frames by nails is possible only if walls are made of wood or foam concrete (AAC). If the wall is made of solid concrete or brick, driving a nail into such a wall is almost impossible, which makes fixation of the grade strip box unreliable. Furthermore, fixing by nails a reference frame levelled off in the required plane of the wall to a required depth of a door or window opening renders provokes vibration from the hammer thus changing the angle of nail entry and interfering with originally perfectly measured level of the reference frame or the pilot guide.

     As a consequence, the referencing of the reference frame to the wall surface around a door or window opening and to reference frames on the walls is impaired. This causes deficiency that becomes evident during installation of door frames, especially with platbands on two sides, by forming cracks under platbands or their distortion. Dismantling of reference frames requires preliminary extraction of nails, which increases labour intensiveness of the process and excessive consumption of wood and time.

     Fixing tools and contrivances with self-tapping screws when performing works associated with plastering the window and door plane esconsons distorts the original level parameters of pilot guides, reference frames or devices. This results in irregularities of the esconson plane and subsequently, defects.

     Dowels can also be used for installation and fixation of tools or equipment on concrete and brick walls when performing works associated with plastering of window and door plane esconsons.  Using of dowels results in  labour intensity and prime cost of works. However, the main disadvantage of using dowels for fixing devices is the need to drill holes in the wall and then converge these holes with holes of the attached device. Often the pneumatic hammer bit changes its direction by 1-3 mm for various  reasons. Deviation of the bit results in displacement of the fixed devices and tools’ level from the originally proposed  parameters. As a consequence, levelling off the necessary tools and contrivances is quite difficult. Digression from the originally defined calculation parameters during installation of tools and contrivances leads to deficiencies at all subsequent stages of finishing works.

     It can not be effectively used for installation and fixation of tools and contrivances during plastering of door and window plane esconsons, plastering of bay windows, cladding with trim tiles or installation of window sills, safes, cabinets etc. Using this device is characterized by low efficiency and poor quality of work associated with finishing of buildings, and is also characterised  by risks of personal injuries.

Best mode for carrying out the invention

     As shown in Fig. 1, the claimed device has an elongated  holder 1, the fastening element (fastener)  2 and two clamping elements 3 and 4.

     Each  clamping elements 3, 4 is made in a form of rod  6 and 7 respectively  and   includes   a threaded  portion     adapted to contact  with the threaded  through-hole 8,9  of the appropriate  end portion of the elongated holder 1.

     According to one of the preferred  embodiment of the  claimed device   the holder 1 is made from solid hard material in the form of I-shaped base (Fig. 1 - Fig. 4). In another best embodiment of the  claimed device  , the holder 1 is made from solid hard material in the form of L-shaped base (Fig. 5 - Fig. 7).

     The fastener 2 (Fig.2) is made in the form of a rod 5.

     The fastener   2 can be configured as a pin and its  end portion 52 preferably   includes   a nut 11 .

     The end portion 51 of the pin-shaped fastening element 2 can be additionally equipped with a dowel 12.

     Pin-shaped fastening element 2 can be additionally equipped with a base flange (plate) 14 (Fig. 3, 6, 7).

     Plate 14 serves as a “base flange” of the device when installing it on the surface of drywall or foamed concrete structures.

     Fig. 8-12  show  various examples of using the claimed device during finishing and construction work such as plastering of the window and door esconsons (Fig. 8), setting the perforated  angle iron on the outer corner of the esconson (Fig. 9 and Fig. 10), laying the first reference  row of tile  (Fig . 11), installing  in-build a safe (Fig. 12) where the following references are  used: the claimed  device 17,  screed board 18, perforated  angle iron 19,  window esconson 20, wall 21, tile 22, plank 23, safe 24, niche 25, wedges 27, reference roller 28, plastered esconson surface 29, door frame 30.


The claimed device operates as follows


     The end portion 51 (Fig. 2) of the fastener  2 of the claimed device is installed in the drilled place (well) for installation and fixation of tools or contrivances. Holder 1 with released  clamping elements 3 and 4 is installed on the rod  5 embedded  to the desired depth.

     Fig. 1 - Fig. 7 show one of the preferred  embodiment of  device with a fastener 2 in the form of a pin. During installation the pin is inserted in the determined  drilled through-hole or the base flange aperture 15, if applicable the I-shaped or L-shaped holder 1 is set through a cylindrical through-hole  10 on the  fastener  2 and then pressed by   nut 11 to the desired depth.

     If the device is installed on a brick or concrete surface, it is recommended to insert the dowel 12 in a drilled through-hole before installing the rod  5 of the fastener 2.

     If the device is installed on the foamed concrete surface, the rod part 5 of the fastener 2 is installed directly into the drilled hole.

     If the device is installed on the drywall surface, before mounting the holder 1 the plate 14 is screwed first through-holes 16 to the desired location then the rod  5 of the fastener 2 is set into the aperture 15.

     Further, the tool  or  contrivance   to be installed and fixed (such as: screed board, slat, lath, perforated metal strip etc.) are put under one of the free ends (end portion 13) of clamping elements 3 or 4 - according to the level or to the lay-out, and, then by holding the said tool  or contrivance this one is  gradually and evenly tightened with the clamping elements 3 or  4. The difference in pressing between clamping elements 3 and 4 will be equal to the thickness of device or tool to be fixed in case if  one of the clamping elements rests on the  tool  or contrivance to be  fixed, and the other -  on  the bearing surface, to which the device or tool are fixed.

     The different   examples of possible using of the claimed device during finishing and construction works are given below.


Example 1.


     Using the device of the invention, type “I”, for plastering walls around the window opening.

     Height and width of the window opening are measured and three straight and smoothly planed at edges wooden slats are selected. Length of the two slats corresponds to the height of a window opening, and the length of the third slat corresponds to the width of a window opening. Width of slats ranges between 100 and 120 mm, thickness: between 20 and 25 mm. The claimed device (having I-shaped holder, the fastening element is in the form of a pin equipped with a star nut,  each clamping element is in the form of a screw with a handle or ear) is used to attach the slats to the concrete wall.

     Slats corresponding to the height of a window opening are set within the opening so that their planed surface is located at the same distance from the window frame and be in the same level with one reference plane of the wall. The place for drilling holes for  rod 5 fastener 2  is selected at a distance from the installed slat. The drilling points are determined visually by drilling approximate uniformly across the length of the corresponding end wall. Deviation of the drilling points can be 15 to 20 mm without affecting the quality of the slat installation. To fix the reference slat on the window opening up to two meters long, it is necessary to have 2 or 3 the claimed devices  for finishing and construction works, and  preferably  3  such devices.

     The dowel 12 is driven inside the drilled through-hole in concrete wall and a pin (fastener 2)  is screwed in. The holder  1 with the released  clamping elements 3,4  (the eye-bolts, each equipped with a disk 131) , is installed on the rod 5 of  the pin, for example  the I-shaped holder 1  is set through a cylindrical through-hole 10  and pressed down with a nut  11 to the desired depth . Next, the slat is set under one of the clamping elements arranged as  the eye-bolt with disc 131 and  then the slat is levelled off . The second clamping element, arranged as  the other eye-bolt with disc 131,  is set beard  against the wall surface, and  - holding the slat - the clamping elements are steadily and uniformly pulled thus adjusting their position.

     The second and third slats are installed  similarly. Perfect accuracy of fixing the levelled off reference slats is achieved by the claimed device, which, due to its design, allows for multiple and multiple-step adjustment of fixed slat. What is important, there is no need to choose a drilling point and drill the through-hole directly under the slat to mount the fastener.  Besides, clamping elements and fixed slat are independent of each other and the rod of the device does not interfere with the installation and adjustment of the slat.

     Reference slats installed at the same level as the esconson with high quality and precision allow achieving accuracy of plastering the planes next to and around the openings. This, in turn, is a guarantee of high quality and precise geometry of future esconsons (control quality point at the interim stage). After plastering walls around the window opening, the references slats are easily and safely disassembled by releasing the clamping elements, unscrewing fastener nut and the device’s fastening element for installation, adjustment and fixation of tools and contrivances.



Example 2.


     Using the device of the invention, type “L”, during finishing and construction works associated with plastering of esconsons.

     Fig. 8 shows the use of the device 17 of the invention (type “L”) for fixing screed board 18 as a screed.

     By the time of finishing the esconsons the walls should be plastered and scoured. The required angle of esconson is set by using an angle  staff. Based on the value of this angle, the reference level of the esconson outer boundary is determined on the plastered wall by installing and fixing a screed board or a reference slat with a claimed device similar to the  described above in Example 1.

     In this case, the esconsons are trimmed after finishing the walls. To prevent the damage of  the wall decor which is  bordered  with  the area of future finishing work at the external angle of esconson, the proposed device of L-shaped form  or I-shaped form  can be used  for finishing and construction works.

     The drilling place for the rod part of the fastening element is selected in the area of plastered esconson. At some distance from the outer boundary of the esconson a well is drilled, a dowel is inserted in the well and a pin is screwed in a dowel. The holder with released  pressure screws of device 17 is installed on the pin; the L-shaped holder is set through a through-hole for fastening element, and the holder is installed. The holder is mounted in such a manner that the clamping element - the screw at the end of a holder with an angular area - is located above the surface of the plastered wall where the screed  is to be fixed.

     The screed board 18 is used as a screed. The holder of device 17 is pressed with a fastener nut to the desired depth. Further, it is recommended to install the screed board 18 under the screw of the clamping element located at the end of holder 1 with an angular area and bring the screed board 18 in line with level parameters. At the same time, another clamping element is beard against the wall 21 of esconson, and - holding the screed board 18 - steadily and uniformly pressed down and fixed with the clamping element’s screw to the wall plane in place where the external angle of the esconson is to be fitted.

     The role of the second screed  during plastering of window apertures (esconsons) is played by the window frame 30 levelled off set in accordance with the standards.

     The redundant amount of bonding plaster is applied to the  surface of wall  21 for the esconson 29 to be plastered. Using two reference points: window frame 30 and screed board 18 fixed on the outer edge of the esconson – the device 28  for plastering the windows and door esconsons  in configuration as shown on Fig.8 may be installed.

     The redundant plaster is removed and the plaster mass is levelled by linear displacement of device 28 for plastering the window and door esconsons according to the reference devices located along the plane of the esconson. After plaster is dried, the reference – a screed board 18 mounted on the outer edge of the esconson – is removed. The reference device is removed by releasing the clamping elements and unscrewing the lock of a fastener for finishing and construction works, after which the surface of the finished esconson 29 is scoured.

     Using the claimed device of the invention and the tools for plastering makes the esconson plastering process faster, more efficient, and raises its quality and safety.

     The device  according to the invention can also be used for plastering outside corners of columns, bay windows, ceiling beams, wall ledges and for installing  perforated painting  angle irons on the  external plastered corners of structures.



Example 3.



     Using the device of the invention upon  installation of painting steel perforated (slotted) angle irons on the outer corners of structures (Fig. 9 and Fig. 10) during finishing works.

     Problems associated with installation of painting angle irons and sometimes impossibility of their installing are caused by the fact that the painting angle irons are made of tough elastic material and are  strongly shaped during their manufacture. Normally, the internal angle of painting angle irons is slightly less than 90? and the angles of structures during finishing works in most cases are right or flat. Therefore, painting angle irons should be properly installed on the outer corner of the structure during finishing works and their outer angles properly secured in a perfectly straight line for the entire period until the adhesive hardens.

     To install the painting steel slotted angle iron by using the device 17 of the invention, the putty adhesive is applied into the inner corner of the painting angle iron 19, after which the angle iron is installed on the outside of the finished corner and its setting parameters are maintained. Next, the excess of putty adhesive is carefully removed with a spatula. The  perforated angle iron 19 is fixed with the screed board 18, which is at least as long as the painting angle iron 19.

     Complete fixation of the screed board 18 by using the device 17, as it was described above (Fig. 9 shows the device of type “I” and Fig. 10 shows the device of type “L”), is carried out after perfectly levelling off the outside corner of the painting angle iron 19 with the edge of screed board 18 according to the set parameters. The fixed screed board 18 remains in this position until the putty adhesive hardens. Due to the claimed device 17 the screed board 18 and the painting angle iron 19 are securely and properly fixed in a perfectly straight line with the outside corner of the angle iron 19 for the entire period of adhesive hardening.

     If the claimed device is used during finishing and construction works a variety of contrivances such as screed board can be applied to result in  enhancing quality, speed, reliability and manufacturability of installing painting angles on different  structures during finishing works. Consequently it also results  in a   dramatic reduction of deficiencies and excessive consumption of materials. The production profitability margins increase.


Example 4.


     Using the claimed device  for laying ceramic tiles, marble and other cladding material on vertical structures during finishing works (Fig. 11).

     One of the main quality criteria applicable to paving of facing tiles can be met only if the horizon level and other installation parameters are strictly observed. In particular, it is essential that the supporting slotted angle irons for the first reference tile row are precisely and reliably secured. This row is fundamental to the  high quality of horizontal joints, and represents a supportive and preventive measure to avoid the subsequent rows of glued tiles from sliding until the adhesive is hardened.

     The device of the invention, both type “I” and type “L”,  ensures fixation of slotted angle irons supporting the first reference row of tiles for the entire period of the adhesive hardening. Simultaneously with the reliable and long-lasting fixation of supporting slotted angle irons it provides for the  safety of surface, tools, contrivances   and the  device itself  , which results in their continued and multiple operation.

     Fig. 11 shows, in particular, the  claimed  device 17 of type “I” used to fix the supporting slotted angle irons with a screed board 18, as an example. The pin screw is driven in the drilled ( through-hole on the vertical surface of wall 21  of the finished structure) with a  dowel placed below the screed board 18. If this is a drywall surface, the base flange  (plate) 14 is additionally used.

     The screed board 18 is installed and accurately fixed by the device 17 along the traced line by adjusting the  clamping elements. Accuracy, reliability and speed of fixing is achieved due to the ability of easily and freely moving the screed board 18 below clamping screws in the range of 15 to 20 mm.

     Therefore  the claimed device allows to use  a screed board or another smooth perforated metal strip of the required length as a support,  and due to this fact it allows  to ensure high-quality, fast, accurate and reliable paving of ceramic tile, marble, and other cladding material on the vertical surface of finished structures. In addition, it is desirable  to use the claimed device during installation of window sills, assembly of in-built safes and cabinets.



Example 5.



     Using the device of the invention, type “I” to install and assemble a safe or a cabinet in a wall niche (Fig. 12).

     Installing a cabinet or a safe in the niche wall is performed after levelling off the wall plane by plastering, for example. First, a niche for the future cabinet or safe is made at the specified location of the wall, with boundaries that are on average 15-30 mm larger than the corresponding cabinet or safe, so that the object can be easily placed in a niche (Fig. 12).

     Parallel to the sides of the niche 25 the required number of the claimed devices 17 of type “I” are installed, by pairs, so that one end of the holder, and a clamping element inside it can be placed in front of the niche 25. Additionally, two planks  23 are used; they should be longer than niche 25, where a safe 24 or a cabinet are installed. The glue of required thickness is applied to the niche 25; its amount should be excessive and squeezed out by the bottom of  safe 24 or cabinet  when it is mounted. After having placed the safe 24 or cabinet, the planks  23 are installed on each side of the niche 25 with the cabinet or safe inside the niche, so that the ends of each plank are located below the niche 25 on the one side, and above it on the other.

     Then each of the planks  are placed under the relevant clamping elements  of devices 17 and then used to gently press the safe 24 or the cabinet into the niche 25 of the wall 21 until the safe or cabinet are installed flush with the wall plane. Vertical level of safe or cabinet 24 of cabinet is achieved by additional wedges 27 that can be installed either at the bottom or on the sides of safe 24 or cabinet. After the glue solidifies the clamps are released , planks  23 are removed; devices 17 are disassembled, and side cracks along the safe 24 perimeter are plastered off. Using  the claimed devices  17 allows to  install  a safe or a cabinet with high precision flush with the wall plane and fixing them firmly and securely. The safe or cabinet cannot move in the niche until the glue hardens.

     The claimed device enhances the quality of finishing works by improving correctness of installation and fixation of tools and contrivances. At the same time, it ensures safety and precision of tools and contrivances’ fixation, provides the possibility of multiple and multi-stage smooth adjustment. Consequently, installation and removal of tools and contrivances is simplified and their damage is avoided, which contributes to their multiple operation. Profitability margins, safety are increased and duration of decorating and finishing works is reduced.
