(54) STRING LIGHT FOR FINISHING WORKS

I

The invention relates to the field of construction of industrial and civil structures and can be applied to individual works in construction when processing both vertical and horizontal surfaces.

Known inventory for plastering, made in the form of slats, made of metal raznobokogo angle, the edges of the shelves to the surface.

The rail has at its ends lugs for fastening screws or pins that have threads on the protruding part for fastening them in the nose. The mounting screws or pins are equipped with a ring-bore nut or welded double-breasted washers with faces for a standard wrench 1.

The closest technical solution to the invention is a string maker for finishing work, which includes a tensioning device, a string, tail rods, adjusting screws, clamping and support rollers, and clamping nuts 2.

The disadvantage of both poppies is the inconvenience of operation and the low quality of surface finish.

The aim of the invention is to improve the quality of surface finish.

This goal is achieved by the fact that in the string canister for finishing work, which includes a tension device, a string, cable holders, adjusting screws, clamping and support rollers and clamping nuts, the tension device is equipped with a lock made with guide rods on which clamping rollers with clamping nuts, and each 10 tailpiece is made in the form of a square, at the ends of which the adjusting screws are mounted, and in the center of intersection of the axes of the square a rigid rod is mounted on which is mounted porn roller, and the lock is fitted with a rigidly fixed on it

15 body adjusting pores.

FIG. 1 shows the installation scheme of string string; in fig. 2 - tailpiece; in fig. 3- section A-.L fng. 2; in fig. 4 - lock with tension device; in fig. 5 is a section BB of FIG. four; in fig. 6 20 section EG of FIG. four.

Claims (2)

String .ma k consists of tailpieces 1, string 2, lock 3 and tensioner 4. (The tailpiece includes case 5, made in the form of a square, at the ends of which adjustment screws 6 are mounted, and in the center of the cross section of the second square is fixed rod 7 the supporting roller 8 put on it. The string 2, the bend supporting rollers 8, passes through the clamping rollers 9 of the lock 3, which are loosely mounted on the ends of the rods 10 protruding above the solid surface of the housing 11 of the lock 3. In this case one 1. The lock 2, after tensioning the tension device 4, is secured in the lock with clamping nuts 12. To secure the tension attachment 4 in the lock housing 11, a protrusion 13 is fastened, on which the counterpart of the detachable connection of the tensioner is attached. made in the form of a hand winch, in the drive of which the limiting moment coupling is installed, prevented. 1. Iush, and the string breaks at the time of its tension. When the string enters the first clamping roller 9, the adjusting support 14 is rigidly fastened on the housing 11, which serves to prevent the stringer holder from breaking away from the surface to be treated, which occurs because the string is clamped in the lock and is located at a greater distance from the surface due to the thickness Corus, than the string, the passage through the tailpiece. The adjusting support 14 consists of a screw 15 and a hinged support 16. Installation of the string is made as follows. The surface to be machined is divided into conditional axial ones with a schus, determined by the size of the tool with which the surface will be machined. At the ends of the conventional axes, holes are drilled in the machined surface, into which the rods 7 of the cable holders 1 are inserted so that the roller 8 contacts the machined surface. At the end of the chain, holes are drilled to install the rods 10 of the lock 3. On the ledge 13 of the lock housing 11, a tension device is attached. The end of the string 2 is rigidly fixed on the first tailpiece I, and then the zigzag-likely is placed on the rollers 8 intermediate tailpiece, the free end of the string 2 is passed through the gland rollers 9 of the lock 3 and secured it to the drum of the tensioning device 4. The tailored housing 5 is turned Thus, the tension forces acting on the string are evenly distributed on the adjusting screws 6 located at the ends of the housings 5. At the same time, by the tension device 4, the string is tensioned. The clamp nuts 12 secure the string in the lock 3. The end of the string is disconnected from the tensioning drum and the latter is removed. Tensioning fixture. Can be used on another area of my surface. When installing tail rods 1, their adjustment screws must be turned out. With the help of the adjusting screws 6 of the string bearers, mounted on the boundaries of the surface to be machined, it is set to the required distance from the surface, i.e. at a distance equal to the thickness of the applied layer. Control of correct installation is controlled by a plumb or level. Over the established sections, the strings pull the cord along which they align all the intermediate sections of the string. To prevent the string from deflecting and creating a rigid base working surface, the string is frozen with a solution at certain intervals. After that, a solution is applied to the treated surface and the surface is leveled with a known device. After covering the applied and leveled layer of mortar, the lock is opened and the lock is removed. To facilitate the removal of the cable holders and the lock, they are lubricated with a water-repellent compound before installation. Claims for finishing work, including tensioning device, string, tail rods, adjusting screws, clamping and support rollers, and clamping nuts, characterized in that, in order to increase the quality of surface finish, the tensioning device is provided with a lock made with guide rods, on which the clamping rollers with clamping nuts are mounted, and each tailpiece is made in the form of a square, at the ends of which the adjusting screws are mounted, and in the center of the intersection of the axes nick rigidly fixed shaft on which the bearing roller is mounted. 2. String box for finishing works according to claim 1, characterized in that the lock is provided with an adjustment support rigidly attached to its body.
