RU187378U1 - Device for plastering a building wall - Google Patents

Abstract

The device relates to the field of construction and can be used for plastering the vertical surfaces of the walls of a building, for example, for external insulation with a monolithic light insulation based on foam glass granules or other similar material. The device comprises flat boards with supporting elements and fastening elements in the form of anchor control devices, including an anchor threaded pin and a pressure cap and a nut placed on it. Anchor control devices are installed directly above the shield, and supporting elements made in the form of Z-shaped profiles are placed under the shield from below and are attached to the plastered wall through the anchor device. To control the position of the shields and their deviation from the vertical, transparent pallets with a polar coordinate grid are additionally mounted on the shields. The device allows performing work not only on internal but also on external walls with quality control of plaster production due to control and timely elimination of deviations of shields from vertical using high-precision geodetic instruments of vertical optical and laser sighting. These processes can be carried out without preliminary installation and subsequent dismantling of steel beacon profiles.

Description

The device relates to the field of construction and can be used for plastering the outer vertical surfaces of the walls of a building, for example, for external insulation with a monolithic light insulation based on granules of foam glass or other similar material.

Known devices for plastering internal walls, containing flat panels attached to the structures of floors and floors using vertical load-bearing elements and intermediate connections [USSR Author's Certificate No. 1308737. The formwork panel is mainly for plastering walls. IPC: E04G 11/20, published on 05/07/1987].

The device involves the supply of a stucco mixture by forcing it into the cavity between the wall and the flat shield through the holes in this shield. The disadvantage of this device is the necessity of feeding the mortar mixture through the aforementioned openings in the boards, which determines the subsequent sealing of the locations of the holes after curing and dismantling of the formwork panels. In addition, this design is not suitable for the installation of monolithic plaster on the outer walls.

Closest to the proposed device is a device for plastering a wall of a building [RF Patent No. 2268344. A method of plastering a wall of a building and a device for its implementation. IPC: E04F 21/02, E04G 11/20, publication: 01/20/2006], adopted as a prototype. A device for plastering a building wall according to the prototype includes flat panels interconnected by fastening elements and supporting elements, the latter being made in the form of an anchor adjusting device, including an anchor threaded pin and an alignment element mounted on it, a pressure cap and a nut. In this case, the flat boards are equipped with couplings with holes and plugs for supplying the solution.

The prototype device is intended for internal plastering and it is difficult to apply it to perform monolithic plastering on the external walls, since it is pre-installed and then dismantled steel beacons, which significantly complicates the complex technological process. In addition, the prototype does not provide a modern system for checking deviations from the vertical when installing and aligning panels before plastering, which affects the quality of the resulting plastering surfaces.

The proposed utility model is based on the task of improving the device for plastering a building wall in such a way as to enable the plastering of external walls by fixing the device to the wall without first installing and aligning the plaster beacons from steel. In addition, it is proposed to improve the control system for deviations from verticality by using for this purpose additionally mounted on flat panels elements of geodetic measurements associated with regulating elements of the position of the panels.

The technical result of the utility model is the simplification and acceleration of an integrated process and improving the quality of work performed by improving the control system.

The device for plastering the wall of the building contains flat panels with supporting elements and fastening elements in the form of anchor adjusting devices, including an anchor threaded pin and a clamping cap and nut placed on it, while anchor adjusting devices are installed directly above the shield, and supporting elements made in the form Z-shaped profiles are placed under the shield below and attached to the plastered wall through an anchor device. To control the position of the shields and their deviation from the vertical, transparent pallets with a polar coordinate grid are additionally mounted on the shields.

The device is represented by graphic materials, where a sectional view shows a wall with a device for plastering it, the same figure shows:

node "A" - anchor adjusting device;

node "B" - installation of anchor fastenings of boards on a support;

knot "B" - fastening a transparent palette on flat boards.

The device for plastering the outer wall 1 of the building includes a flat shield 2 with a supporting element 3 located under the shield 2 and fastening elements in the form of an anchor adjusting device, including an anchor threaded pin 4, adjusting nuts 5, and pressure caps 6, and the adjusting device is placed above the shield 2, and below the shield 2, a support element 3 is fixed in the form of a Z-shaped profile, which is attached to the plastered wall 1 through the anchor device 7. The shield 2 can be fixed in the profile 3, for example, by a wedge 8. In the upper part of the cabbage This 2 is secured with a screw clamp 9 to a transparent palette 10 made of glass in a frame 11 with a polar coordinate grid 12 applied to the glass.

Any intermediate, shown in the drawing, the stage of use of the proposed device is as follows. In the wall 1, through a previously made and hardened lower part of the plaster, a hole is drilled and the anchor device 7 is fixed, a Z-profile 3 is attached to it with a nut 3. Such fasteners 7 need at least two on each shield 2. Above the future position of the shield 2, in to the wall 1, a hole is drilled and the anchor threaded pin 4 is fixed. The bottom of the shield 2 is inserted into the gap between the wall 1 and the Z-shaped profile 3 and fixed with a wedge 8, as shown on node B; and the upper part of the shield 2 is installed between the nuts 5 and the clamping caps 6 on the anchor threaded pin 4, as shown on the node A. Several are also needed on one shield 2 of the upper adjustable fasteners 4 shown.

Between the indicated upper mounts 4, a transparent palette 10 made of glass in a frame 11 with a polar coordinate grid previously deposited on the glass 12 is secured to the shield 2 by a screw clamp 9 on the glass 10. A laser or light vertical beam from a vertical sighting and verified geodesic device is incident on this glass 10 shown in the drawing by a dash-dot line. By rotating the nuts 5 with the clamping caps 6, a state is achieved so that the beam of sight is in the center of the concentric rings of the grid 12 of the palette 10 in the frame 11. This means that the required vertical position of the shield 2 is achieved. The same measurements and adjustments are made several times along the shield 2. and the calibrated cavity between the wall 1 and the shield 2 serves the plaster mixture, it is compacted and maintained until the necessary stripping strength is achieved. After that, the shield 2 is removed, loosening the fastening with nuts 5 and knocking out the wedges 8, and then the anchor pins 4 and 7 are also removed. After that, the plastering process is repeated at a higher level.

Thus, the proposed device for plastering the external walls of the building allows such work not only on the internal but also on the external walls to control the quality of the plaster production due to the control and timely elimination of deviations of the shields from the vertical using high-precision geodetic instruments for vertical optical and laser sighting. Moreover, these processes can be carried out without preliminary installation and subsequent dismantling of steel beacon profiles, which simplifies and accelerates the complex technological process.
