Description

The invention relates to the field of ground construction, in particular to equipment and decoration of buildings, the essence of which lies in the method of installing metal beacons of the type PM6 or PM10 (hereinafter PM) for high-quality plastering of surfaces (wall, ceiling) and for floor screeding devices.

A known traditional method of manufacturing beacons from mortar, including the following operations:

- hanging the plane before plastering;

- device of beacon marks from quick-hardening materials;

- the device of beacons from the solution, which are based on manufactured brands.

(Shepelev A.M. Stuccoing. High school, 1970).

With the advent of metal plaster PM, it became possible to replace mortar beacons with them.

Common disadvantages of this method are low productivity, high complexity and fairly high requirements for the professional skill of the performer. In addition, mortar beacons are fragile, their surface is rapidly deformed and erased when pulled along them with a plaster rule, and when installing metal PMs, it is difficult to provide a predetermined position due to the fluidity of the solution.

Also known is the technology that uses reusable metal inventory plaster beacons (Shepelev A.M. Stuccoing. High school, 1970). The process of installation and regulation of such beacons differs from the mortar described above in the simplicity, speed and reliability of installation. But they also have their drawbacks. For example, metal beacons are made from precisely aligned corners with a cross section of 25 × 25, 30 × 30, 35 × 35 mm, which limits the minimum thickness of the plaster layer. They have a large metal consumption and dimensions, and also limit the height of plastering due to fasteners. According to this technology, in addition, it is necessary to seal with a solution those places where the lighthouses stood, which leads to additional work and costs.

An object of the invention was the development of such a method of installing a plaster beacon, which would eliminate the disadvantages of known technologies and ensure simplicity, reliability and accuracy of installation.

To solve the problem (achieve the above technical result), a device was proposed consisting of the following parts:

- template support (standard trapezoidal rule with holes for attaching the PM to it with a cable clamp, then the template);

- two original brackets (the bracket is a wooden block of square section (1) with a cavity for placement inside the bar of the fastening and adjusting element [self-tapping screw (2) with washers (3) and springs (4)] and a viewing hole; the cavity has a longitudinal axial through a cylindrical shape of variable cross-section; an auxiliary mark (5) is applied on the bar, showing the extreme position of the template with PM with a minimum layer of plaster). See Figure 1;

- wedges (for adjusting the position of the brackets).

The proposed method of installing beacons in practice can be described by the following algorithm (for example, the wall):

- places are marked for future lighthouses (extreme, 20-30 cm away from the corners, and intermediate with a step of 1.3-1.7 m) by beating vertical lines with a construction plummet with paint;

- holes for the dowel are drilled at a distance of approximately 60 cm from the floor and ceiling and the brackets (6) are installed so that the working surface of the bracket coincides with the drawn vertical line;

- the laser plane builder (BOB) is set in the corner of the wall so that the beam plane fights off the minimum possible thickness of the plaster layer, taking into account the width of the template, focusing on the auxiliary marks (7) on the brackets. Additionally, the passability of the installation of the template with PM between the plane of the beam and the surface is checked;

- the perpendicularity of the working surface of the bracket relative to the plane of the beam is checked by the joiner's square. If necessary, using the adjusting wedge (8), the bracket is set to the required position, i.e. perpendicular to the plane of the future plastered surface;

- marked on the working surface of the bracket in the middle of the beam marks (e) for installing the template with a beacon;

- small portions of quick-hardening mortar (11) are applied along a vertical line on the wall (10) in 15–20 cm increments. Then the template (12) with PM (13) is pressed into the solution and fixed according to the marks on the brackets with self-tapping screws and washers (14);

- cable clamps (15) are cut after the solution has solidified, self-tapping screws are unscrewed and the template and brackets are removed; See Figure 2.

Thus, it is proposed to consider:

- The method of installing the beacon, which consists in using a laser plotter and fixture, which includes the following interconnected parts: a support template, two original brackets and adjusting wedges, and is characterized by the fact that it allows you to fix the specified position of the beacon profile (PM) in the process installation on quick-hardening solution.

- A method of installing a beacon, characterized in that a standard trapezoidal rule with holes for attaching the PM to it with a cable clamp is used as a support template.

- A method of installing a beacon, characterized in that it is possible to manufacture a solution beacon instead of PM.

- A method of installing a lighthouse, characterized in that the original bracket is a wooden block of square cross section with a cavity for placement inside the bar of a fastening and adjusting element (self-tapping screw with washers and springs) and a viewing hole; the cavity has a longitudinal axial through cylindrical shape of variable cross section; an auxiliary mark is applied on the bar, showing the extreme position of the PM template with a minimum layer of plaster.

- A method of installing a beacon, characterized in that when installing the bracket in a predetermined position, an adjusting wedge is used.

- A method of installing a beacon, characterized in that the use of a spring and a viewing hole in the bracket provide the convenience and speed of its adjustment.

- A method of installing a beacon, characterized in that the original brackets are not only a support, but also perform the function of determining the position of the template support relative to the marked surface using a laser plane builder.

- A method of installing a beacon, characterized in that the fastening and adjustment of the brackets, as well as the installation of support templates with beacons on them, can be carried out both on vertical and horizontal surfaces.

Advantages of the above method of installing a beacon:

- the proposed method allows for more accurate installation of the beacon and thereby obtain high-quality surface finish;

- the use of the device can significantly simplify and speed up the installation of the beacon;

- a standard trapezoidal rule is used as a template;

- a metal galvanized PM is used as a beacon, which is convenient in operation and is widely available for sale;

- the proposed method also allows you to make a mortar beacon;

- with the specified method of installing the lighthouse, it is possible to attract lower-skilled performers.
