Description

The utility model relates to the field of construction, in particular to the device of concrete floors.

A device for the formation of level beacons is known, patent for the invention No. 2166041. With the help of level beacons, the installation horizon is aligned during the installation of elements of prefabricated building structures, equipment and other objects. The technical result is the creation of a structurally simple device for the formation of level beacons from a mortar, convenient and reliable in operation and providing high quality manufacturing of beacons. The device is equipped with a guide element, which is installed inside the guide pipe. The geodetic rail is located inside the guide element. On the side surface of the guide element, on a part of its length, diametrically arranged vertical grooves are made. The geodetic rail is rigidly connected by screws with a thrust holder. The screws are placed in vertical grooves, and the stopper is interfaced with the guide element, a level is set on the top of the geodetic rail.

A disadvantage of the beacons thus obtained is the lack of direction for the leveling tool, which leads to significant errors when leveling the floor.

It is known to align surfaces under the lining, the Internet address http://www.remontiruem.ru/story/10457.html which includes the installation of lighthouse guide rails to ensure the correct level and evenness of the surface of the screed. The guide can be made of scraps of water pipes, wooden blocks, a special profile or plaster. Guides are laid in 1-2 meters. The level of the top of the guides should correspond to the required height of the surface of the screed. This is achieved by laying under the guide wedges. Then, a long level checks the correct location of the guides on the plane and slope. To protect the guides from shear and subsidence when pouring screeds, they are fixed every 20-40 cm with gypsum or alabaster. After making the screed, the pipes or bars are removed and the resulting recesses are closed with a solution. Gypsum rails are more laborious to install. Before installing them, plaster beacons are installed every 1-2 meters throughout the room. The height of the beacons should correspond to the required thickness of the screed in this place. Lighthouses are checked by level. Then, between the two neighboring beacons, a gypsum mixture is poured and pressed down with a leveling tool mounted on two neighboring beacons. The spatula removes excess gypsum from the sides of the leveling tool, and it is carefully removed. Thus, all the beacons are connected, forming a guide.

The disadvantage is the high complexity associated with the complexity of vertical adjustment and fixation of the guides, the low accuracy of the installation of the guides in one plane, the lack of monolithic concrete slab, since it is divided along the entire length in the places of installation of the guides by seams formed after filling the voids left after the removal of the guides, causing cracks along the seam.

The closest in technical essence and the achieved effect is a device for leveling the floor (RF patent No. 2293164, IPC E04F 15/00, publ. 02/10/2007) including beacons made in the form of guides that are level and fixed from movement, and from two of the sides in each guide is made through an opening in which the adjusting sleeve with a shoulder abutting against the side surface of the guide and a hole offset from its outer diameter through which the axis passes renewed with the possibility of vertical movement in a groove made in a corner fixed on the surface to be leveled, the axis being made with an annular protrusion included in the groove of the adjusting sleeve, and nuts were installed on both sides of the axis, one of which fixes the vertical position of the axis, pressing it with the ring the protrusion to the corner, and the other presses the adjusting sleeve and the guide to it.

The disadvantage of this invention is the complexity and laboriousness of the installation of the device, which leads to large time costs in preparing the device for operation, as well as the fact that at least 2 such devices are required for operation.

The task of creating a utility model is:

- reducing the complexity and simplifying installation of the device.

The technical result consists in increasing the speed of leveling the floor, increasing the quality of the leveled surface.

The technical result is achieved in that in the device for leveling the surface of the floor, including the guide rail and a screw adjustable device, the guide rail is made with a support base located perpendicular to its axis, while they are interconnected by corners fixed at one end to the guide rail, the other on a support base , the guide rail is mounted on four vertical supports with the possibility of its free movement, to the left and to the right of the guide rail, between two verticals lnymi supports are spaced two transverse support impaled on them and secured with screws, screw adjustable devices are installed in the middle of the transverse supports of the rack guide shaft and connected to the supporting foundation via z-shaped profile, wherein the ends of the guide rail mounted laser receivers.

The essence of the utility model is illustrated in the drawing:

figure 1 shows a device for leveling the surface of the floor.

Device for leveling the floor surface, figure 1, consists

1. The vertical support of the guide rail;

2. The fixing screw of the transverse support;

3. Cross support;

4. L-shaped profile of the fastener of the base of the guide rail connected to a screw adjustable device;

5. Guide rail;

6. The supporting basis of a directing lath;

7. Corner for fastening the supporting base of the guide rail;

8. Screw adjustable device;

9. Handle screw adjustable device;

10. The fastener plate of the supporting base;

11. A bolt of fixture of the supporting basis.

12. Laser receiver

When constructing high-precision concrete floors, the entire total floor area is divided into maps (a smaller area compared to the total area that can be prepared, filled with concrete mix and wiped one team at a time). In the construction estimate, the level of the concrete floor screed is established, i.e. how many millimeters should the thickness of the concrete slab be. During the reception of concrete mixture, a device is installed in a given map for leveling the floor surface with two workers. With the help of laser receivers (level is set) and a screw adjustable device (height adjustable), the guide rail of the device for leveling the floor is set to a predetermined level of the concrete floor screed. A device for smoothing a concrete surface (vibrorail) is installed at one end perpendicular to the guide rail of the device for leveling the floor surface. With the passage of the device for smoothing the concrete surface along the entire length of the guide rail of the device for leveling the floor, the concrete mix is aligned along the entire length of the guide rail of the device. Then, the device for leveling the floor is transferred to the next part of the card.

The guide rail 5 is located on four vertical supports 1, which allows it to be installed at the time of receiving the concrete mixture, in contrast to the prototype in which it is mounted in advance.

The vertical supports 1 of the guide rail 5 allow it to make free movement, i.e. for the device and leveling the surface of the floor, only one guide rail is required, in contrast to the prototype in which at least 2 pieces are required for operation.

The vertical supports of the guide rail do not require a separate fixation, in contrast to what is required when installing the prototype.

The mounting screws of the transverse support and the screw adjustable device allow you to set the floor level to 500 mm.

The rigidity of the guide rail is achieved due to the support base, in contrast to the L-shaped corners.

Unlike the bubble level installed in the prototype, the guide rail is set to a predetermined floor level using laser receivers located on it, which increases the accuracy, ease of installation, and reduces the time spent on preparation for work.

Application of the utility model allowed:

- significantly reduce the time for preparatory work on leveling the floor,

- reduce the complexity of adjusting and fixing the guides in a given position

- improve the quality of the leveled surface.
