Description

The utility model relates to the field of construction, in particular, to the construction of a plaster beacon made in the form of a profile from a polymer material.

From the description of the international application WO 2017/093995 A1, IPC E04F 21/05, publ. 06/08/2017, the known design of a plaster beacon made of flexible sheet metal and including the first and second shelves, provided with holes and connected by a V-shaped protrusion.

For attaching the lighthouse to the wall, a special holder is provided, which is made of metal or polymer material.

The presence of the holder increases the labor intensity of installing the plaster beacon, the range of parts used in the construction and the cost of plastering.

In practice, as described in the description of WO 2017/093995 A1, the plaster beacon is usually glued to the wall with a small amount of plaster or glue.

The disadvantage of the widely spread method of fixing the plaster beacon with plaster mortar or glue is the possibility of sliding the plaster beacon over the plaster or glue until it dries, which causes the plaster beacon to shift and reduce the accuracy of plastering.

For the closest analogue, the design of the plaster beacon is adopted, known from the description of the patent US 7757450 B2, IPC E04B 1/68, publ. 20.07.2010

The structure of the closest analogue is made of polymeric material and includes the first and second shelves provided with rows of holes, and a V-shaped protrusion between them.

The disadvantages of the stucco beacon known from US Pat. No. 7,757,450 B2 are:

- unsatisfactory rigidity of the base, which negatively affects the quality of the plaster surface and the complexity of the work;

- insufficient reliability of fixing the lighthouse on the plaster or adhesive layer;

- the possibility of displacement of the beacon due to insufficient adhesion.

The objective of the claimed utility model is to improve the design of the plaster beacon known from the patent US 7757450 B2, by eliminating the existing drawbacks.

The technical results to be achieved by the utility model consist in increasing the profile rigidity, eliminating the displacement of the beacon in the process of gluing and increasing the accuracy of the work performed.

The above technical results are achieved in a plaster beacon made of polymer material and including the first and second shelves provided with holes, and a protrusion of a V-shaped cross-section located between the shelves and connecting the shelves to each other.

The technical results are achieved by the fact that longitudinal projections are made on the rear surface of the shelves.

In this case, in the embodiment of the plaster beacon, the projections can be made, for example, of a triangular cross-section.

Moreover, in the best version of the utility model, the shelves can be connected by a partition.

The utility model is illustrated by the following pictures.

FIG. 1 shows a cross-section of a plaster beacon taken as the closest analogue;

FIG. 2 shows a cross-section of a plaster beacon;

FIG. 3 shows a plaster beacon in an inverted position;

the protrusion of the V-shaped cross-section is directed downward.

Positions in the images indicate:

1 - plaster beacon; 2 - the first shelf of the lighthouse; 3 - second shelf of the lighthouse;

4 - protrusion of the V-shaped cross-section; 5 - holes in the shelves;

6 - protrusions on the rear surface of the first shelf;

7 - protrusions on the rear surface of the second shelf;

8 - partition between shelves.

The utility model can be implemented in the construction of a plaster beacon 1, made of polymer material and including (see Fig. 2, 3): the first shelf 2 and the second shelf 3, in which the rows of holes 5 are made, and the protrusion 4 of the V-shaped cross-section, located between the shelves 2, 3 and connecting the indicated shelves 2, 3.

To implement the utility model, the following changes are made in the design of the plaster beacon.

Longitudinal projections 6, 7 are formed on the rear surface of the shelves 2, 3. In an embodiment of the plaster beacon, the projections 6, 7 can be made, for example, of a triangular cross-section. Those skilled in the art can envision protrusions of a different cross-section, such as rectangular, semicircular, etc.

The proposed technical solution allows you to simply and effectively increase the rigidity of the profile, eliminate the displacement of the beacon during the gluing process and improve the accuracy of the work performed.

The protrusions 6, 7, in fact, are stiffening ribs that increase the rigidity of the profile flanges.

The protrusions 6, 7 prevent the beacon from displacement in the transverse direction during the gluing of the beacon with plaster or glue.

The protrusions 6, 7 objectively increase the area of interaction of the profile with plaster or glue and increase the adhesion of the profile to the plaster or glue.

The number and location of the protrusions 6, 7 are selected based on the achievement of the optimal value of the rigidity of the parts of the plaster profile.

In the best version of the utility model, the shelves 2, 3 can be interconnected by the partition 8. The partition 8 effectively increases the rigidity of the profile 1.

The applicant has formed by extrusion from PVC and tested a plaster beacon with the following geometric dimensions:

- profile width 20 mm;

- the height of the protrusion of the V-shaped cross-section is 10 mm;

- wall thickness of the projection of the V-shaped cross-section 0.7 mm;

- partition thickness 0.7 mm;

- maximum shelf thickness 1 mm;

- the diameter of the holes in the shelves is 5 mm;

- the height of the protrusions on the back side of the shelves is 0.3 mm;

- number of projections 4.

The plaster beacon is used in a traditional way.

Lighthouses at a distance less than the length of the rule, through holes 5 in the shelves 2, 3 in a vertical position, are glued to the wall surface with plaster or glue.

Then plaster mortar is thrown onto the surface of the wall between adjacent beacons.

After that, a rule is applied to the tops of the protrusions of the beacons and carried out with a rule with a slight pressure to smooth out the plaster solution and remove its excess.

Plaster beacons do not separate from the wall after use; they also serve as reinforcement for the plaster layer.

The plaster beacon of the proposed design can also be successfully used for floor screed.

In the course of the conducted patent research, the world novelty of the proposed technical solution was established.

The production and operation of the prototype of the plaster beacon confirmed the industrial applicability of the utility model and its compliance with the stated technical results.
