RU156024U1 - BRACKET FOR INSTALLING A PLASTER BEACON PROFILE HOLDER - Google Patents

Abstract

An arm for mounting a holder of a stucco beacon profile made of a rectangular wooden block of square cross section, characterized in that it has a longitudinal axial through cavity of a cylindrical shape of variable cross section for placement of a fastening and adjusting element in this cavity, consisting of a self-tapping screw with washers and a spring, and a side viewing hole, also on the bar marked with auxiliary marks showing the extreme position of the holder with a minimum layer of plaster.

Description

The utility model relates to devices for installing stucco beacon profiles of type PM6 or PM10 both in the vertical and horizontal plane.

In practice, the traditional method of installing such profiles is widely used, including the following operations:

- hanging the plane before plastering;

- device of beacon marks from quick-hardening materials;

- pressing the profile into the applied mortar cakes taking into account the lighthouse marks.

The disadvantages of this method are the high complexity and fairly high requirements for the professional skill of the performer. Also, with such an installation, it is difficult to provide a predetermined position of the beacon profile due to the fluidity of the solution.

A device is known under the name “Lighthouse profile mounting device for plastering walls, ceiling and floor screed” (described in the patent for utility model RU 131824 U1, class F16B 13/00 (2006.01). This fixing device consists of a rectangular platform with two antennae located at the edges, dowels and self-tapping screws.The principle of operation is as follows:

- hanging the plane before plastering;

- beating of vertical lines with a plumb line with dyed thread;

- drilling holes along the line with a step of 30-40 cm and inserting a dowel into them;

- installation using a self-tapping screw of this mounting device in the dowel;

- adjustment of the thickness of the plaster layer with a self-tapping screw using a building level or a laser plane builder.

A similar principle for securing the beacon profile is also represented by the following devices:

1) “Device for fastening the beacon under the plaster (options)”

(Patent for utility model RU 88083 U1, class F16B 13/00 (2006.01));

2) "Device for mounting a beacon"

(Patent for utility model RU 131825 U1, class F16B 13/00 (2006.01)).

Common disadvantages of such point-mounting devices are the high complexity and low accuracy (a large number of supports) in the adjustment and installation of plaster beacons. Therefore, the authors set themselves the task of creating such a device that would provide at a new professional level an increase in productivity and manufacturability of installation work and would be distinguished by its simplicity of design, low cost and availability of materials.

To solve this problem, a bracket was proposed in the form of a rectangular bar (1) of square cross section made of wood with a cavity for placement of a fastening and adjusting element inside the bar (self-tapping screw (2) with washer (3) and spring (4)) and a viewing hole; the cavity has a longitudinal axial through cylindrical shape of variable cross section; auxiliary marks (5) are marked on the bar (marks indicate the minimum possible thickness of the plaster layer, taking into account the width of the holder). See FIG. one

Advantages of the above bracket design:

- a standard wooden block with a cross section of 50 × 50 mm is used, which is simple to manufacture and convenient to use;

- the design of the bracket allows you to establish cheap mass industrial production;

- As part of the fastening and adjusting element, standard components are also used, such as a self-tapping screw, washer and spring, which are widely available on sale.

The scheme of work on the example of the wall with the proposed bracket can be described in the following way (apply only in pairs):

- places for future lighthouses are marked (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 about 60 cm from the floor and ceiling, and the brackets (1) are installed so that the working surface of the bracket coincides with the drawn vertical line;

- the laser plotter is set, focusing on the auxiliary marks (2) on the brackets, so that the beam plane strikes off the minimum possible thickness of the plaster layer taking into account the width of the holder (a standard trapezoidal rule with holes for fastening with a cable tie of a beacon profile is used as a holder). Additionally, check the template (holder + profile) patency between the beam plane and the wall surface;

- the perpendicularity of the working surface of each bracket relative to the plane of the beam is checked by a joiner's square. If necessary, using the adjusting wedge (3), the bracket is set to the desired position, i.e. perpendicular to the plane of the future plastered surface;

- marks (4) are marked on the working surface of the bracket in the middle of the beam for mounting the holder with a profile;

- are applied along a vertical line on the wall (5) in increments of 15-20 cm of quick-hardening mortar cake (6). Then the holder (7) with the profile (8) is pressed into the solution and fixed according to the marks on the brackets with self-tapping screws and washers (9);

- after the solution has hardened, the cable clamps (10) are cut, the screws are unscrewed and the holder and brackets are removed. See FIG. 2
