Description

Device and method for plastering walls

Technical field

The invention relates to the field of construction and is intended for plastering walls in order to obtain a flat or textured surface.

State of the art

A known method and device (Patent 2083782. Cherny A.G., METHOD FOR PLASTERING A BUILDING WALL AND FORMWORK PANEL FOR ITS IMPLEMENTATION, November 25, 1992), according to which the panels are mounted in the panel, attaching it to the pillars of the supporting elements via lanyards. On the deck of the panel, decorative parts, replaceable matrices with decorative molding cells are fixed, which, if necessary, are filled with decorative mortar and covered with plates or ribbons, as well as removable matrices and punches. The windows in the shields with matrices overlap with ribbons with a longitudinal section. Boxes are inserted into openings, in a working position, with molding gaps, and spatial frames and a grid are attached to the wall via rods. Some frames are fixed after the panel is put into operation when the rods are passed through cuts in the tapes. After that, boxes and detachable dies are attached to the deck, blocking the windows. Then molding fill the new cavity with plaster mortar. Plates, tapes and fasteners are removed from the molding cavity and, after hardening of the plaster mortars, the relief surface of the wall is removed. There is also known a method and device (Patent Zh2268344, Verstov V.V. Khaikovich D.M. Budanov B.A., METHOD FOR PLASTERING A BUILDING WALL AND DEVICE FOR ITS IMPLEMENTATION, 11.10.2004), which can be used for plastering external and internal surfaces of walls when used in combination with mortar-mixing modular plaster pumps. The essence of the invention lies in the fact that in the method of plastering the walls of a building, including the installation of panels and their connection between the fastening elements, a vertical molding cavity is created between the panels and the wall surface into which the stucco mortar is injected. Before installing the shields on the wall surface, anchor control devices are installed at predetermined points and inventory beacons at the edges of the molding cavity. The position of the mounted panels is regulated in a plane perpendicular to the plane of the wall. The solution is injected into the molding cavity of the mortar pump through couplings with removable plugs placed on the working surface of the panels. After hardening the solution, the panels are dismantled, and the anchor devices are removed.

A device is also known (Patent ЖУ52609, Tambiev XM, DEVICE FOR APPLICATION AND LEVELING OF BUILDING SOLUTION 05.11.1993 - the closest analogue), which contains a guide frame and a working body mounted on the frame with the ability to move in a plane perpendicular to the plane of the frame, and along it. The working body has a drive and is made in the form of a U-shaped composite shield. The side walls of the shield are spring-loaded relative to its base. On the outer surface of the side walls a calibration scale is made.

DETAILED DESCRIPTION AND EMBODIMENTS OF THE INVENTION With a detailed description of the claimed invention, it is not advisable to dwell in detail on its known design and technological features. It is necessary to describe in detail only its distinctive features, in particular, a device containing a body in the form of a metal frame consisting of two parts: a fixed frame 1 (Fig. 1) and a retractable frame 2 with the possibility of its extension to a predetermined height, which also ensure a strictly even parallel to the wall stroke of the movable mechanism. The casing is structurally and functionally interconnected with the movable plaster feed mechanism with the possibility of its translational-reciprocal movement by sliding along the guide bearings.

The sliding frame 2 is mounted with the possibility of sliding along the guide bearings and extending all the way to the ceiling, thereby forming, with the help of mounted screw braces, of a rigid and fixed device structure. The frame is equipped with protrusions with their stops in an interconnected the theme of lighthouse strips and thereby the formation of a predetermined plastering surface and the trajectory of the movable stucco feeder, which is interconnected with a node installed on the body in the form of a manual or electric winch to drive the stucco feeder in a direction from floor to ceiling.

The support frame-beacons 4 and the stops of the beacons 3, as well as screw extensions with a clamping screw 17, which ensure the structural immobility during operation, are also installed on the metal frame. In addition, a winch 14 is installed with a cable and a manual or electric drive, a roller 15, which provides tension to the cable going from the winch 14 to the movable mechanism, clamping bars 16, which ensure the holding of the forming tape, and a drive chain 9, which rotates the rollers 7 conveyor.

The movable mechanism of the device is composed of long cylindrical rollers 7 of the conveyor, providing a circular run of the conveyor belt with respect to the wall, of the conveyor belt 5, ensuring the transfer of the stucco mixture from the hopper to the wall. The moving mechanism also includes a hopper 12 for the mixture of plaster, roller sprocket 8, providing sequential rotation from the chain 9 to the conveyor roller 7, a leveling bar 11, which provides clamping and leveling of the surface of the plaster mixture on the wall, bearings 13, providing a smooth and even course the entire movable structure, and the nest 18, in which the roll of the forming tape 6 is installed. Forming tape used if necessary to obtain a textured surface of the wall.

The proposed design allows you to fix the device in a pre-adjusted position on the beacons, to provide pouring the mixture into the hopper and its further movement along the conveyor belt from the hopper to the wall. As a result of rotation of the conveyor belt and simultaneous lifting of the mechanism along the wall surface from floor to ceiling, uniform application of the mixture and its alignment along the wall are achieved. The speed of the conveyor belt is equal to the speed of movement of the movable mechanism along the wall along the guides of the frame structure. Thus, the claimed invention allows to obtain a plastered smooth or textured wall under the lighthouse, ensuring the achievement of the specified technical result. The proposed device allows you to ultimately carry out the technological sequence of the claimed method of plastering walls, which produce preliminary preparation of the wall for plastering and lay the plaster mixture relative to the outer side of the wall. At the same time, the space between the wall and the adjacent points of the cylinder-shaped rollers and the leveling bar of the movable plaster feeding mechanism, which are moved from the lower part of the wall to the upper one, resting them on guides of device frames installed in one plane. As a result of morning the plaster mix laid in this way is made and the flat or textured form of the plastered surface is made with a leveling strip or forming tape

In more detail, the operation of the device and the set of operations of the method of plastering the walls, it is advisable to characterize the following way. In the beginning, beacon strips 4 are installed on the floor and ceiling along the length of the wall, they are leveled with levels and then the apparatus is brought into working condition. If it is necessary to obtain a textured surface, a forming tape 6 is attached to the clamping strips 16 (smooth or textured) and is passed through the leveling bar 11 along the conveyor belt 5 under the hopper, where the roll of tape is placed in socket 18 (if you need to plaster the wall with the result of obtaining a smooth surface , then installation of the forming tape is optional). The device is brought in and rests, with extended parts on the frame - stops of beacons 3, to beams-beacons 4 and with the help of screw extensions (clamping screws 17) is brought to the desired height and tightened.

Next, the movable mechanism is lowered to the lower position and the solution is poured into the hopper 12. Using a manual or electric winch 14, the winch cable thrown over the roller 15 pulls the movable mechanism upward along the wall. The movement of the movable mechanism causes the sprocket of the roller 8 to rotate, since a fixed chain 9 is rolled through the sprocket of the roller 8 and the pressure rollers 10. The speed of the conveyor belt 5 is equal to the speed of the movable mechanism along the guides of the frame, which is achieved by matching the diameters of the sprockets a roller 8 with a diameter of the conveyor roller 7. The sprocket of the roller 8 and the conveyor roller 7 are fixed to each other. The movement of the sprocket of the roller 8 rotates the rollers of the conveyor 7 and drives the conveyor belt 5 from the hopper 12 to the wall. Thus, the mixture is transferred in the required amount and the space between the wall and the leveling strip 11 is poured. The stucco mixture is pressed into the space between the wall and the leveling strip 11 by moving the conveyor belt 5, and the leveling strip 11 creates pressure and at the same time glides up the plaster mixture. The pressure in the lower part (at the leveling bar) is higher than in the upper part and therefore the excess mixture is pushed up. Thus, the mixture is returned to the hopper and is used for subsequent use.

After plastering one strip, the screw extensions 17 are loosened, the lower part of the forming tape 6 is released from the pressure strips 16, the whole mechanism (see Fig. 1) is moved away from the wall, leaving the forming tape on the plastered wall, after a few minutes the forming tape can be removed and applied repeatedly. To speed up the process, several tapes are used. Next, the device is rearranged end-to-end with the left or right edge (depending on which direction you need to continue plastering) to the border of the already plastered wall, and the process is repeated again. Industrial applicability and achievement of a technical result.

As follows from the above, the achievement of the technical result can be achieved only inextricably interconnected set of all the essential features of the claimed device and method, as reflected in the claims. The claimed significant distinguishing features were created on the basis of processing the results of experimental studies, analyzing and summarizing them and known from published data sources, interrelated with the conditions for achieving the technical result indicated in the application, as well as using creative intuition. Distinctive features of the claimed objects give reason to conclude that the technical solution is new, and the totality of the claimed claims in connection with their inevitability is about its inventive step, which is also proved by their detailed description above.

Compliance with the criterion of industrial applicability)) of the proposed method devices is proved both by their specific implementation, their detailed description, and the absence in the claimed claims of any features that are practically difficult to realize on an industrial scale.

In conclusion, it is advisable to note that when realizing the invention, the problem was solved to implement a method of plastering walls using mechanization of hard physical labor, which gives an increase in productivity with a significant reduction in time and financial costs. Among the main consumer goods It is advisable to note the achievement of the following results:

• Obtaining immediately a smooth plastered wall under the lighthouse, excluding intermediate operations, such as: installing beacons, applying the plaster manually or by machine, removing excess mixture, smoothing the bumps and filling cavities, applying a second leveling layer.
