Description

The proposed technical solution relates to construction and can be used to perform the leveling screed floors.

According to the well-known technology in construction, in the manufacture of the leveling screed before pouring mortar, beacons (guiding level marks) are set up, using various metal profiles. The fastening of such “guide rails” to the base can also be different: with the help of solutions or metal structures. The disadvantages of such beacons are as follows:

- surface roughness of the finished screed due to the final stiffness of the guide rail;

- high complexity associated with the need for dismantling and cleaning rails.

In the patent literature there were no technical solutions aimed specifically at improving structures for the manufacture of beacons, only general for finishing work or leveling surfaces, and surfaces are understood to mean vertically located planes of walls, panels, etc.

For example, a device is known for implementing a method for performing construction and finishing works in interior decoration. This device contains two guide rails, each of which has a hollow stand of rectangular cross section with open ends, on the lateral faces of which there are longitudinal risks and holes with the possibility of installing a finger in them to accommodate a plumb line, and on the back face of the hollow stand there is a strap having a supporting plane and guide planes protruding beyond the ribs of the rear edge of the rack, two removable flanges, each of which is arranged to be placed and secured to the hollow rack from the side of the open ends there is a plate located perpendicular to the hollow rack, in which the latches are installed in the holes with the possibility of adjusting the height of their part protruding above the surface of the plate, removable gaskets made with the possibility of their installation on the side of the protruding part of the clamps, and a rack spatula having a working surface and working edges made with the possibility of its placement between the side faces of the installed and fixed guide rails with the provision of its movement along the guide planes of the planks I direct their slats perpendicularly guide rails, or the working surface of at least one sealing lip in the level plane. (See p. Of Russia No. 21623287, publ. 02.20.01., Cl. E 04 F 21/04)

The disadvantages of this technical solution are that it is not intended for the manufacture of beacons when pouring and screed floors, especially when using quick-drying cements. It would be unprofitable to use it for the above purpose: too many auxiliary operations and time are required to prepare the device for work and conduct the work itself. In addition, as with well-known methods, this technical solution has a high complexity associated with the need to dismantle and clean the rails, as well as the roughness of the surface of the finished screed due to the finite stiffness of the guide rail.

The technical solution proposed below will avoid these drawbacks. The technical result of the utility model is to increase the speed of work in the manufacture of beacons for leveling floor screed, as well as reducing the cost and complexity of these works.

The achievement of this technical result was due to the fact that the device for the manufacture of beacons with leveling screed floors includes a forming device and a cutting device. The forming device is made in the form of a box-shaped case having at least one open end and consisting of an upper part, in the form of a hopper intended for filling the solution, and a lower part intended for molding a beacon. The cutting device is equipped with a retaining wall and a bed having guides on both sides, between which a knife is mounted with the possibility of its vertical movement on carriages moving along the guides in the horizontal direction. In this case, the cutting device is equipped on both sides with a level and an adjusting screw, which ensure the horizontal position of the bed, as well as screws that regulate the vertical movement of the knife.

This device is convenient in operation and provides fast and high-quality manufacture of beacons by forces of two to four people, while the manufactured beacons are absolutely resistant to all mechanical stresses that arise when laying the main screed solution.

Figure 1 shows a device for the manufacture of beacons, General view.

Figure 3 - cutting device

A device for the manufacture of beacons with leveling screed floors contains a forming device 1 and a cutting device 2. The forming device is made in the form of a box-shaped case 1 without a bottom with one blind 3 and the other 4 open end. The upper part of the molding device 1 is made in the form of a hopper 5, designed to fill the solution, and the lower part 6 is designed to form a beacon.

The cutting device 2 is provided with a retaining wall 7 and comprises a frame 8, on which box guides 9, bubble levels 10 and adjusting screws 11 are provided on both opposite sides, ensuring the horizontal position of the frame 8.

Inside the guides 9 there are moving elements 12 on which the carriages 13 are mounted. Between the carriages 13, a knife 14 is arranged with the possibility of vertical movement, made in the form of a plate reinforced with stiffeners. The knife 14 at any level has a power reserve sufficient to abut the retaining wall 7 in one direction and in the other direction, so that a molded strip of mortar passes between the retaining wall 7 and the knife 14. The movement of the knife 14 is vertically controlled using screws 15 and fixed with screws 16 in a predetermined position after determining the vertical mark of the cutting height of the lighthouse and, accordingly, the height of the leveling screed floors.

The device operates as follows. Lighthouses are made of quick-drying solutions in the form of strips with a width of 12 to 16 cm and any length specified by the dimensions of the room. Along the marking line of the location of the lighthouses, a forming device 1 is installed, in the hopper 5 of which the solution is poured and rammed at a level obviously higher than necessary for the lighthouse.

After removing the forming device 1 on the molded solution, a cutting device 2 is installed with a retaining wall 7 close to the molded solution. On the bubble levels 10 with two screws 11 provide a strictly horizontal position of the frame 8 and, accordingly, the guides 9, so that the cross section of the beacon is horizontal. Then, after determining the vertical mark of the cutting height of the lighthouse using screws 15, the knife 14 is set to the required level and fixed in position with the screws 16.

After performing the installation operations, the top of the molded solution is cut off by manually moving the knife 14 across to the retaining wall 7. The cutting device 2 is moved to a new beacon, and the cut-off part of the solution is poured out again into the forming device 1, which is installed to make the next beacon or to continue the previous one. If the beacons are no longer required, the cut off solution is used to fill the screed on previously exposed beacons. After cutting, the surface of the lighthouse is wiped with a manual metal grater, the edges are cut vertically. After the solution has hardened, after 8-10 hours, the beacons are ready to fill the screed.
