Description

The invention relates to techniques for construction finishing work, and more particularly to tools and devices for laying floor tiles.

A device for laying tiles (see patent for invention RU 2312958, MKI E04F 21/22, publ. 12/20/2007), including horizontal guides made in the form of I-beams, a metal support rail having the ability to move along horizontal guides, and equipped with a device for leveling the surface of the defective floor with a preliminary screed.

A conductor for laying floor tiles is also known (see USSR author's certificate, No. 183359, IPC E04f, publ. 06/17/1966), made in the form of an enclosing frame with a slider installed with the ability to move around the frame, leveling the solution to a given thickness.

A common disadvantage of these devices is the insufficiently high quality of the resulting tile floor. When operating it under alternating loads and stresses caused by thermal deformations, it is possible to peel tiles from the underlying layer. This is due to the fact that these devices do not provide the formation of an optimal surface relief of the adhesive layer on which the tile is laid. With an arbitrary shape of the relief of the surface of the layer, which is created by these devices, closed air cavities can occur under the tiles during their laying, in which there is no adhesion of the tile to the adhesive layer.

A conductor for tiled floors is also known, selected as a prototype (see patent for invention SU 1694816, MKI E04F 21/22, publ. 30.11.1991), containing two tubular guides with adjusting elements, a movable template with position locks and rollers made with gutters repeating the shape of the guides. Adjusting elements in the form of screws with bushings are attached to the bottom of the guides, and holes for latches having the shape of an ellipse are formed on top, the large axis of which is perpendicular to the axis of the guides.

The movable template (shaper of the adhesive layer) includes front and rear corners, bolted together. The horizontal shelves of the corners are directed in different directions from the longitudinal axis of the template, while the horizontal shelf of the front corner is pointed. The front and back corners of the template are the shaper of the adhesive layer. A strip of mortar is placed in front of the pointed horizontal shelf of the front corner. The movable template begins to move along the guides, while the front corner cuts off the excess solution, and the lower planes of the horizontal shelves of both corners smooth the remaining layer of the solution, forming the thickness of the layer and the relief of its surface, the irregularities of which are distributed arbitrarily.

Thus, this conductor has the same drawback as the devices discussed above, namely, the insufficiently high quality of the resulting tile floor. In addition, it has a rather complicated design.

The objectives of the invention are to improve the quality of tiled flooring and simplify the design of technical means.

The tasks are solved in that in a device for laying floor tiles containing two horizontal guides and a mobile shaper of the adhesive layer with N pairs of rollers mounted on it in pairs so that the axis of rotation lie in one vertical plane perpendicular to the longitudinal axis of the shaper of the adhesive layer, moreover, N pairs of rollers are made with the possibility of moving them and fixing vertically on the side walls of the shaper of the adhesive layer, and the horizontal guides are made of a metal profile, for example gauge, pipes of rectangular cross section and in the process of laying tiles are in contact with the rollers of the mobile shaper of the adhesive layer, the latter is made of the front and two side flat walls bonded to it, forming two straight dihedral angles from the front, and a replaceable plate is installed on the bottom of the front wall , the lower edge of which is made in the form of a comb. The profile of the teeth of the comb of the interchangeable plate has a rectangular or triangular, or trapezoidal, or wavy shape.

When laying the first row of tiles, the first and second horizontal guides are mounted parallel to each other on the floor screed, one of the removable plates with a rectangular, triangular, trapezoidal, or wave-like comb teeth is installed on the front wall of the adhesive layer, and the shaper rollers are in contact with the first and the second horizontal guides between which the laid tile is located.

When laying the second and subsequent rows, the second horizontal guide is installed parallel to the edge of the tiles of the previously laid row, on the front wall of the adhesive layer former one of the removable plates with a rectangular, or triangular, or trapezoidal, or wave-like shape of the teeth, rollers mounted on the first side wall the shaper of the adhesive layer in contact with the second horizontal guide, and the rollers mounted on the second side wall of the shaper, with the front surface of the tiles earlier a laid row, the lower part of the outer surface of the second side wall being in contact with the end surface of the tiles of the previously laid row.

Horizontal guides are made of rectangular pipes or channels, which gives them the necessary rigidity and lack of deflection.

The distance between the outer surfaces of the side walls of the adhesive former is chosen equal to the width of the tile.

The invention is illustrated graphically.

In FIG. 1 shows a view of the shaper of the adhesive layer from the front wall in the position when laying the second and subsequent rows of tiles in the embodiment with one pair of rollers (N = 1). In FIG. 2 is a plan view, and FIG. 3 - sections aa. FIG. 4 illustrates a surface profile of an adhesive layer created by a former and a plan view.

In FIG. 1 shows: former 1 of the adhesive layer, its front wall 2 with a removable plate 3 mounted on it, the lower part of which is made in the form of a rectangular comb, rollers 4, a horizontal guide 5 made of a rectangular pipe, fixing screws 6, tile 7, adhesive layer 8, screed 9. One of the rollers 4 is in contact with the horizontal guide 5, and the second is in contact with the front surface of the tiles 7 of the previously laid row.

In FIG. 2 shows: the first 10 and second 11 side walls of the former 1 of the adhesive layer fastened to the front wall 2 and forming two straight dihedral angles with it, the lower part of the outer surface of the second 11 side walls is in contact with the end surface of the tile 7.

In FIG. 3 depicts a clamping screw 12, a mounting plate 13, an axis 14, nuts 15, 16 of the washer 17, 18 of the groove 19.

The rollers 4 are mounted on the side walls 10; 11 with the possibility of moving along the vertical through grooves 19 and fixing at the desired height using the clamping screws 12 and nuts 15. The axis 14 of the rollers lie in one vertical plane and are perpendicular to the longitudinal axis of the former 1 of the adhesive layer. Axes 14 are fastened with straps 13 by threaded connections. On the axes 14, rollers 4 are mounted, fixed by nuts 16 and washers 17 of antifriction material, for example, fluoroplastic. The rollers 4 are expediently made of a polymer material, for example, of caprolactam. The ends of the axes 14 are included in the grooves 19, which eliminates the rotation of the mounting plates 13 with the rollers 4 relative to the axis of the fixing screws 12.

In FIG. 4 shows a transverse profile of the surface of the adhesive layer 8 created by the former 1 of the adhesive layer after its movement and a top view of the surface of the layer with channels oriented along the direction of movement.

The procedure for working with the proposed set of elements for the device of tiled floors is as follows. Before laying, the tile (if necessary) is cleaned of dust and other impurities and putty solution is applied to its wrong side. Putty tiles are removed and served for laying.

The laying of the first row of tiles is also carried out using two horizontal guides - the first and second, installed parallel to each other on the floor screed at a distance slightly exceeding the width of the laid tiles. On the front wall 2 of the shaper 1 of the adhesive layer (see Fig. 1), the one selected from the set of interchangeable plates is installed, the comb shape of which is optimal for the type of glue used, its consistency, viscosity, and the thickness of the required layer. By adjusting the position of the rollers 4 vertically, the necessary clearance is established between the teeth of the comb of the removable plate 3 and the upper point of the relief of the floor screed, after which the rollers 4 are fixed in this position. The former 1 of the adhesive layer is installed in the place of the beginning of laying at the ends of the horizontal guides, laid out between the side walls 10; 11 (see Fig. 2) of the shaper 1 adhesive solution, then move the shaper 1 in the direction of the adhesive solution along the first and second horizontal guides. Behind the shaper 1 of the adhesive solution, a layer of adhesive solution of the desired thickness is formed with the surface profile shown in FIG. 4. A tile is laid on this layer, recessing it into it, with the horizontal surface of the tiles and the thickness of the seams between them being controlled.

The arrangement of the elements of the kit when laying the second and subsequent rows of tiles is shown in FIG. 1 and FIG. 2. In this case, use one horizontal guide 5, placed parallel to the edge of the previously laid row of tiles 7. Another supporting surface for the rollers 4 of the former 1 of the adhesive layer is the front side of the previously laid tiles.

If the surface of the floor screed is close to "ideal", then the tile can be laid without using horizontal guides.

Vertical movement of the rollers 4 of the former 1 set the desired gap between the teeth of the combs of the removable plate 3 and the upper relief point of the screed 9 of the floor and fix the position of the rollers 4 with clamping screws 12 (see Fig. 3).

The shaper 1 of the adhesive layer along the supporting surfaces (horizontal guide 5 and tile 7) is moved simultaneously with the outer surface of the side wall 11 of the shaper 1 pressed to the ends of the previously laid tile 7. On the formed adhesive layer 8 with the surface profile shown in FIG. 4, lay the tile so that its surface is flush with the surface of the previously laid tile.

Due to the formation of an optimal profile of the surface of the adhesive layer (Fig. 4), during the laying of the tile when it is recessed into the solution layer, air is squeezed out from under the tile through the formed channels communicating with the atmosphere, which prevents the formation of air cavities under the tile and ensures reliable adhesion of the tile to the adhesive layer.

Thus, the proposed device significantly improves the quality of tile floors and their service life under conditions of alternating loads and the presence of thermal stresses.

The advantage is also the simplicity of the design.
