Description

The invention relates to construction, and in particular to devices for leveling solid floor and wall cladding materials when glued to a surface to be clad.

When gluing solid facing materials, in particular ceramic tiles, to obtain an aesthetic result, it is necessary that all the tiles lie in the same plane without any differences at the joints, forming a flat surface with even connecting joints between the tiles.

A device for laying tiles, consisting of horizontal rails and vertical racks, connected elements, cone inserts and a pattern for the depth of laying of tiles (patent RU 2230863, IPC E04F 21/22, publication 2003).

This device allows you to quickly and accurately produce sticker tiles of various shapes and sizes, while maintaining a given depth of laying tiles. However, this device is expensive and bulky, and its use is justified only for large volumes of finishing work.

There are several devices known for leveling ceramic tiles in the plane, the designs of which and their principle of use are similar to each other. These devices usually consist of two parts. The first part is a plastic holder having a flat vertical rod, in the lower part of which there is a support platform, and the upper part has a shape adapted to interact with the second part. The second part is a plastic working fluid having a base on which it rests on the tiles from above, and a structure that allows it to interact with the upper part of the stem of the first part. When they interact, the lower supporting platform of the first part moves towards the base of the working fluid of the second part and a clamping force is created between them (patents: US 08429878, IPC Е04В 1/00, E04G 21/00, publication 2013; WO 2011121476, IPC E04F 15 / 02, publication 2011; WO 2008118418, IPC E04F 21/00, publication 2008; US07954300, IPC E04F 21/18, publication 2011; US 20110011031, IPC E04F 21/18, publication 2011 and others. )

To use the devices described above, the first part is placed with the lower support under the tiles at their joints, the second part is located on top of the tiles with its base, and when the working fluid interacts with the stem, a clamping force is created between them, due to which the tiles are aligned. After the adhesive solution has dried, the devices are knocked down with a hammer, during which the first part is destroyed.

The design flaw of these devices is as follows: they can only be used when laying tiles with smooth edges; 2 devices are required on each side of the tile; the first part has a complex shape and is destroyed during the dismantling of the device; the second part is also subjected to shock loads during the dismantling of the device and, after several uses, is also destroyed; Some of the above devices require the use of additional devices to create the necessary clamping force.

The technical result of the proposed invention is to simplify the design, as well as reduce or eliminate all of the above disadvantages.

The technical result is achieved in that the vertical rod of the claimed device is a round rod, on the upper end of which there are holders for fingers, which allow to hold the entire device in a vertical position and rotate the rod itself around its own axis, which in its upper part is approximately equal to 1 / 3-1 / 2 of its height, also has a thread with an outer diameter greater than the diameter of the cross section of the rod itself, through which the rod is placed with the possibility of longitudinal of movement, a working fluid having a flat base and a through hole with a thread corresponding to the size of the thread in the upper part of the rod, at the lower end of which there is still a small section of thread with an outer diameter equal to or smaller than the diameter of the cross section of the rod, through which to its lower end a small flat washer is wound.

The round rod may be metal or made of some other durable material.

The diameter of the rod may be equal to or less than the desired thickness of the inter-tile seam.

Circular protruding ribs can be made on the flat base of the working fluid to reduce the coefficient of friction between the base of the working fluid and the surface of the tiles.

The support washer on top may have ribs that will define and help align the thickness of the tile joints. This can be four ribs located radially at an angle of 90 degrees relative to each other, to install the device at the intersection of the tile joints of four tiles, or there can be three ribs, two of which are radially at an angle of 180 degrees relative to each other, and the third rib is located to perpendicularly to install the device at the junction of three tiles.

The claimed tile alignment device is shown in the drawings, where in FIG. 1 device is presented frontally, assembled, in the working position, the working fluid and the supporting washer are made in section; in FIG. 2 shows possible versions of the support washer, top view; in FIG. Figure 3 shows the possible placement options for devices in the inter-plate joints, top view.

The claimed device for leveling tiles consists of three parts interconnected by means of threaded connections. The first part is a round rod 1, at the lower end of which there is a small section with a thread 2, the outer diameter of which is equal to the diameter of the rod. In the upper part of the shaft there is also a thread 3, occupying approximately 1 / 3-1 / 2 of its height and the outer diameter of which is larger than the diameter of the shaft, and the rod ends at the top with finger holders 4, with which the device can be held vertically and rotated around it own axis. The second part is a working fluid 5, which has a round flat base 6, outer ribs 7 and a through threaded hole 8, the dimensions of which correspond to the size of the thread 3 located in the upper part of the rod 1. The third part is a flat washer 9, having a threaded in the center hole 10, the dimensions of which coincide with the thread 2 in the lower part of the rod 1.

The claimed device for leveling tiles is used as follows. On the rod 1 is first put on from the bottom up, and then the working fluid 5 is screwed on, and on the lower end of the rod 1 a thrust washer 9 is fastened by means of a threaded connection. Next, the device is assembled inserted between the tiles 11 so that the thrust washer 9 is under, and the working body 5 over the edges of adjacent tiles. Then, holding the device vertically with one hand using the holders 4 available on the rod, with the other hand rotate the working fluid 5 on the rod 1, lowering it down until the pressing force with the base 6 of the working fluid aligns the edges of adjacent tiles 11 in one plane . After the adhesive composition has hardened, the working fluid 5 is screwed back up the rod 1, weakening the clamping force, after which the rod 1 is twisted and pulled out by the holders 4 in its upper part, leaving the supporting washer 9 under the tile.

In FIG. 2 shows three main of the possible embodiments of the support washer 9, a top view, and in FIG. 3 shows three main options for the location of the device in the tile joints, each of which is determined by the version of the used washer 9.

The washer 9A is universal and can be used when installing the device anywhere on the tile joints. In order for the washer from below to better press the edges of the tiles, additional through holes can be made in it to better squeeze out the adhesive solution that got on top of the washer or spring-up notches protruding upwards can be made, which will make it possible to align tiles with a difference in thickness. With this washer, the device can be installed in all three options G, D and E (Fig. 3). With option D, the thickness of the seam will be equal to the diameter of the metal rod, and for options D and E, additional (but inexpensive) devices may be needed to align the tile joints (you can use sticks with the same cross section, crosses stuck vertically, etc.).

The supporting washer 9B has on its upper surface 4 ribs located radially at an angle of 90 degrees relative to each other. A device with such a washer is installed according to option D (Fig. 3), at the corners of four tiles (at the intersection of the tile joints), and in this case the thickness of the ribs on the plate will set the width of the tile joints.

The support washer 9B has 3 ribs on its upper surface. Two of them are located radially at an angle of 180 relative to each other, and the third rib adjoins them perpendicularly. A device with such a washer is installed according to option E (Fig. 3), when joining three tiles, when during their laying one row of tiles is offset relative to the other row. The thickness of the ribs on the washer will also determine the width of the tile joints.

The claimed device for leveling tiles has the following advantages:

- installation and dismantling of the device does not require much effort and special skills;

- installation and dismantling of the device does not require auxiliary devices;

- when dismantling the device does not need to destroy anything and use brute force;

- the consumable is only a support washer, which is small, easy to manufacture and can be made of inexpensive materials (cheap plastic, polyethylene, thick cardboard, etc.);

- a supporting washer with ribs can provide different thicknesses of tile joints;

- the device has three installation options;

- the device can be used at the corners of the connecting tiles, which halves the required number of devices used, in contrast to the case when the devices are installed at the edges of the tiles (two devices per side);

- the device can be used when laying tiles with uneven edges.
