Description

The utility model relates to the field of construction, in particular to the construction of a plaster beacon.

Plaster construction beacons are a guide profile, a long element in the form of a figured profile, which is designed for quick, high-quality, rough leveling of the base of brick, concrete, gas-block straight sections of walls or floor screed, to create a flat surface of the plaster thickness specified by the project from 6 mm to 10 mm or more, using cement or gypsum plaster mortars, manually or mechanically. Plaster beacons are manufactured industrially from various materials: aluminum, galvanized steel, polymeric materials.

Galvanized lighthouses have gained wide popularity among craftsmen, but they have a number of disadvantages. Galvanized beacons (in a pack) are heavy, they can bend during transportation, rust during storage, lift and erase during use, over time, a building rule, leave metal microparticles in plaster solutions, which later appear as rust through the finishing layer. A galvanized beacon is problematic to dispose of.

The main requirements for plaster beacons are clear geometry and rigidity. Significant errors in the geometry of the profile entail an increased consumption of expensive plaster mixture, which will subsequently lead to an overspending of expensive finishing putty masses, increase the time spent on this section, and also increase the total time for the completion of the object.

The closest analogue of the claimed plaster beacon is a device (utility model patent RU 181233 U1 (F16B 13/00, 11/27/2017). A well-known device for leveling the plaster layer consists of two elements: a plaster beacon and a beacon fastening. in the form of an inverted T-shaped profile product in cross-section and includes a vertical post, as well as a base provided with holes on both sides of the vertical post.

The disadvantages of the closest analogue are

unsatisfactory rigidity and strength of the entire profile, including the rack itself and the connection with the figured shelf (head), which may affect the safety and quality of this profile during transportation, unloading and delivery to points of sale and to objects;

complication of installation and loss of time when using the fastening system, as well as the difficulty to ensure the presence of such fastening, since it is sold separately, and fastening consumption cannot always be predicted;

uneven distribution of the load that occurs under the action of the rule when distributing the plaster mix between the beacons (the figured shelf at the point of junction with the rack is subjected to increased load in the form of torsion; due to the fact that the figured shelf protrudes to the right and left for a certain distance, tangential stresses arise);

insufficient rigidity of the wall, base and profile as a whole, subject to torsion;

the complexity and duration of installing the profile using a level or plumb line and, as a result, the loss of time at the stage of installing beacons;

The objective of the claimed utility model is to improve the characteristics of the plaster beacon by changing its structural part, as well as to create a profile with greater stability and low price. Reducing the total time at the stage of installation of plaster beacons. For the proposed solution, several main tasks can be distinguished:

increasing the rigidity of the lighthouse design itself, which will improve the quality of the plaster surface and reduce material overruns;

speeding up the installation of beacons, increasing the productivity of plastering at the stage of leveling walls or screeds (reducing the cost, which means increasing competitiveness or additional profit by reducing the presence at the facility);

improving the quality of plastering work due to the geometrically correct installation of beacons;

reduction and minimization of losses for defects during the transportation of products to distributors and to objects from points of sale;

reducing the influence of weather factors, including temperature fluctuations on the geometry of a plastic product;

introduction of professional installation of beacons using modern laser levels or levels that affect the accuracy and speed of installation of beacons.

The technical result, which the utility model is aimed at, is to obtain the most even plaster layer at minimum economic costs (minimizing the overspending of plaster solutions, reducing the time for installing and leveling the plaster layer, ease of use), which is achieved due to the accuracy of the installation of the plaster beacon, including use of laser levels.

The technical result is achieved by the fact that the plaster beacon is made of a polymeric material in the form of a profile product in the form of an inverted brand and includes a central post, as well as a base, according to the proposal, the central post in the upper part in cross section has the shape of a round head, and in the middle part it contains shelves in the form of a herringbone, located diametrically opposite each other and protruding relative to the vertical axis of the central pillar at the same distance, equal to no more than 1/4 of the width of the base. Polyvinyl chloride is used as a polymeric material. The lighthouse is made by extrusion. The base is provided with round holes on both sides of the upright. The base is provided with square holes on either side of the upright. The surface of the base, in contact with the solution for fixing the plaster beacon, is made ribbed with zigzag ledges. The base on both sides in a cross section contains at the ends of the sides.

The utility model is illustrated by the following drawings.

In FIG. 1 shows a general view of the claimed plaster beacon.

In FIG. 2 shows a cross section of a plaster beacon.

In FIG. 3 shows a diagram of the installation of a plaster beacon on the wall (side view).

In FIG. 4 shows a diagram of the installation of a plaster beacon on the wall (top view).

The plaster beacon is made in the form of a profile product in the form of an inverted brand (Fig. 1, Fig. 2) and includes a base 1 and a central (vertical) post 2 located perpendicular to the base and dividing it into two equal halves. The base 1 is provided with holes 3 (∅ 4-6 mm) along the entire length of the profile, on both sides of the vertical post (Fig. 1). The central post in the upper part 4 in cross section has the shape of a round head with a diameter of d=2-3 mm. This form is more stable (not subject to deformation), because. the load arising under the action of the rule when distributing the plaster mixture between the beacons is evenly distributed along the axis. The execution of the cross section of the upper part of the rack in the form of a round head allows you to stabilize the load from the action of the rule, because. it is distributed from the center of the circle along the axis of the column, minimizing shear stresses, torsion and destruction of the profile at the junction of the head and column.

In the middle part, the vertical post contains shelves (shoulders) in the shape of a herringbone 5, located diametrically opposite each other and protruding relative to the vertical axis of the post 2 at a distance L1 equal to no more than 1/4 of the width of the base L (preferably, L1=1/4L±0 ,1L, where L is the width of the base). It has been experimentally established that this size of shelves 5 is the most convenient when installing a plaster beacon using laser levels.

The base of the beacon 1, from below, at the junction (attachment) to the mounting solution in the cross section contains zigzag protrusions 6 across the entire width of the profile for additional strength and better adhesion to the mounting solution. Small, zigzag ledges 6 are made symmetrical with corners at tops and bottoms of 90°. The base 1 on both sides in the cross section has rectangular or rounded sides 7 (thickening) at the ends to give the beacon additional strength and clear geometry.

Shelves 5 can be both horizontal and inclined from 35° to 90° (angle α in Fig. 2) to the vertical stand. One beam of the laser level is directed to the middle part (approximately the middle) of one shelf 5, and the other is directed to the outer edge of the opposite shelf 5. The upper part 4 of the lighthouse stand is a laser beam separator.

The base can be provided with round (Fig. 1-3) (Fig. 4) holes on both sides of the vertical post

The plaster beacon is made of a polymeric material, in particular, it is made of PVC (polyvinyl chloride) or fiberglass reinforced PVC. Products from conventional PVC are used in the temperature range from -15°C to +66°C. The PVC stucco beacon is made by extrusion, which makes it possible to increase its rigidity and improve its geometry.

The plaster beacon is used as follows.

With the help of a tape measure and construction chalk, the installation sites of the beacons are marked on the wall or on the floor. As a rule, for convenience and high performance, the distance is set to the same. The distance between the beacons depends on the width of the plaster rule, on the experience of the master and the area of plastering work (the average step of the guide beacons is set less than the length of the plaster rule by 20 cm. Most often it is 80 cm. The location of the extreme plaster beacons from the inner corners is from 10 cm to 30 They retreat from door or window openings at up to 15 cm. The beacon on the base 1 is attached vertically to the horizon using a mounting solution in the form of small blotches applied along the installation line of the beacon, and can also be fastened with self-tapping screws installed in holes 3, or with special fasteners for a beacon.The beacon is applied by its base 1, the surface of which is ribbed with zigzag protrusions 6, adjusted for the required gap specified by the project and fixed in solution. accurately set beacons, which positively affects the quality of the plaster surface and reduces the time for subsequent elimination of defects. The installation can be carried out both with one laser level and with the help of two levels at the same time. On one or two shelves 5 in the form of a herringbone, a vertical beam is directed from a laser placed along the wall (base). The lighthouse is exposed with the necessary clearance equal to the thickness of the plaster layer (6 mm or 10 mm, or more at the request of the project). The protruding, inclined shelf of the beacon 5 must be aligned with the vertical laser beam. At the same time, opposite the wall and the installation site of the lobe profile, another laser level is installed (Fig. 3-Fig. 4), (which ensures the vertical installation of the poppy profile), the beam of which is set strictly horizontally to the given floor level and is directed to the second shelf in the form of a Christmas tree, which must match this beam. The beams of these laser devices do not intersect, since between the shelves there is a rack horizontal to the base of the beacon. After installing the beacon, when the required “plaster gap” is set, and the beacon is well fixed to the base of the wall by drying the mounting layer, you can start filling the inter-beacon space with plaster. The solution is thrown onto the wall with a trowel until it is completely filled and the required thickness is set by beacon profiles. By the rule of the bar, the solution is pulled from the bottom up in zigzag movements, along the beacons, as if along guides, while excess solution is removed and filled with it again where there is not enough solution. The operation is performed until the plaster surface is completely leveled. Then you can move on to the next part of the wall. Further, depending on the required strength of the under-dried plaster layer, PVC beacons can be pulled out or left in the wall. In the simplest version, after incomplete drying, the beacons are removed from the plaster, and the grooves from the beacon are sealed with the same solution, best of all with the remains of the mortar that was used for plastering.

To speed up the production of plastering work and the subsequent ones, in certain design solutions, you can not remove the plastic beacons from the plaster. This method attracts many craftsmen, as it speeds up the preparation of walls for subsequent finishing. PVC beacons are left in the plaster layer, but on top of the plaster they are covered with a layer of putty reinforced with a masking glass mesh or painting fiberglass. In our design, the herringbone-shaped side shelves and zigzag ledges on the base allow the beacon to adhere much more firmly to the plaster layer and avoid delamination of the profile in the matrix of plaster compositions, as a result of which thread-like cracks can appear.

Example 1

The width of the base of the plaster beacon is 18 mm ± 5%, the height of the vertical stand is 6 mm ± 5%. The diameter of the round head of the central pillar in the cross section of the upper part is 2-3 mm. The base is provided with holes with a diameter of 5 mm with a distance between them of 10 mm, on both sides of the vertical post and contains zigzag protrusions on the lower surface in contact with the mortar for fixing the plaster beacon. Wall thickness (base and vertical pillar S) - 0.5-1 mm. Shelves in the shape of a herringbone are located opposite each other at the same level and protrude relative to the head of the rack at a distance L1 = 5 mm ± 5%

A plaster beacon is installed using two laser levels at the same time. The lighthouse is exposed with the necessary plastering, working gap equal to the thickness of the plaster layer of 6 mm planned by the project, it can be attached to the wall using self-tapping screws installed in the holes with plastic dowels, installed previously along the lighthouse mounting line at a distance of approximately 30 cm each. One beam of the laser level is directed to the middle part (approximately the middle) of one shelf 5, and the other is directed to the outer edge of the opposite shelf 5. The beacon stand 2 is a separator of laser beams. With the help of self-tapping screws installed in the holes of the beacons, and then in the sockets of the dowels, the beacon is fixed on the wall according to the exposed beams of the laser levels. Further, the finished plaster mortar is thrown onto the wall with a trowel and leveled with the rule, as described earlier. After the plaster layer has dried, the beacons are pulled out.

Example 2

The width of the base of the plaster beacon is 20 mm, the height of the vertical stand is 10 mm ± 5%. The diameter of the round head of the central pillar in the cross section of the upper part is 2-3 mm. Shelves in the shape of a herringbone protrude relative to the head of the rack at a distance L1=5 mm±5%. The base is provided with holes with a diameter of 5-6 mm with a distance between them of 10 mm ± 5%, on both sides of the vertical post and contains zigzag protrusions on the lower surface in contact with the mortar for fixing the plaster beacon. Wall thickness (base and vertical pillar S) - 5-1 mm ± 5%. A plaster beacon is installed using two levels at the same time. The laser level, located along the wall in the extreme right or extreme left side, inserts a vertical gap specified by the project documentation or adopted for applying the layer thickness necessary to level the wall. The layer thickness can be any from 6 mm to 10 mm or more. The installation of beacons starts from the opposite side of the laser level, so that subsequent beacons do not block the installation beam. Next, the first beacon profile is installed, which is installed strictly vertically to the laser beam directed frontally to the wall at the installation site of the first beacon. The lateral inclined shelf in the form of a herringbone should coincide with the vertical laser beam, which will ensure the vertical installation of the beacon itself. The choice of the guide bar for the beam depends on the location of the side laser, if the side laser is on the right, then the bar on the left is selected, if the side laser is on the left, then the bar on the right is selected.

After the vertical installation of the beacon on the frontal laser device, we combine the opposite side of the inclined bar with the beam running along the wall, which sets the most important amount of the plaster layer. After the laser beam is aligned with the beacon bar along the entire length, the beacon installation is considered completed. We move the frontal level to the width of the plaster grip of about 800 mm and repeat the installation procedure. To simplify the processes, or if laser levels are not available, the verticality of the plaster beacon can be achieved using a level or plumb line, and the marking and preparation of the wall for plastering can be achieved using the marking method known to plasterers. The beacon is attached to the wall using a mounting solution, with a clearance necessary for leveling equal to a layer thickness of 6 mm. Next, the solution is thrown onto the wall with a trowel and leveled with a rule, as described earlier. After the plaster layer has dried, the beacons remain.

The presented examples confirm that the claimed plaster beacon allows performing plastering works in accordance with the requirements of the project, SNIP approvals and other documentation.
