Description

The invention relates to construction, namely to the creation of construction equipment and can be used for an automated process of plastering and puttying walls.

The well-known "Method of plastering the walls of a building and a device for its implementation", including the installation of anchor, regulating the position of the panels, devices at predetermined points of the wall, the subsequent installation of the panels and their connection between the fastening elements with the formation between the panels and the wall surface of the vertical molding cavity into which the solution is pumped with a mortar pump through couplings with removable plugs placed on the working surface of the boards, and the subsequent dismantling of the boards after hardening the solution and removing anchor devices operatio ns.

A device that implements the proposed method includes flat and L-shaped shields connected to each other by means of fasteners to which couplings with removable plugs are attached, having fasteners for the discharge hose of the mortar pump, and anchor control devices (RF patent No. 2268344, publ. 01/20/2006, IPC E04F 21/02, E04G 11/20).

The disadvantages of this device are: low productivity, additional labor and loss of time for installation and installation of panels, and after hardening of the mixture - the operation to dismantle the panels.

All of the above ultimately significantly increases the cost of work.

Also known is the "Method of applying the stucco mixture to the walls of the building and a device for its implementation" (RF patent No. 2377375, publ. 12/27/2009, IPC E04F 21/00), including the installation of supporting telescopic racks, individual flat panels, their connection between fastening elements, with the formation of a vertical cavity between the shields and the wall surface, into which a highly mobile mixture is pumped, the subsequent dismantling of the shields and racks after the mixture has hardened. In this case, before mounting the supporting telescopic racks on the surface of the floor and ceiling of the room, linear markings are made at a certain distance from the wall surface.

A device for applying stucco mixture to walls includes supporting telescopic racks, individual flat panels having a working surface on which couplings with an opening for supplying stucco mixture are installed. The device has fastening elements for adjacent shields placed around the perimeter of the shield, in the form of L-shaped rods with handles made of durable nylon.

The disadvantages of this device are also low productivity, additional costs and loss of time for linear marking before mounting telescopic racks, installing and installing shields, and after hardening the mixture, dismantling operations for racks and shields. All of the above ultimately significantly increases the cost of work.

The problem to which the invention is directed is to automate the process of continuous plastering (puttying), with a significant increase in productivity, reduction of labor costs and time saving, reduction in the cost of work.

Plaster (putty) machines and stations of such German companies as Putzmeister, PFT, M-Tes are known, which are a tank for preparing the working mixture, an electric drive, a compressor and a hose with a gun for manually applying the plaster (putty) mixture to the wall, we accepted as a prototype. The technology of plastering (puttying) using the above units is as follows.

After preparing the working mixture in the unit, the latter is applied to the surface to be treated by means of a mortar gun held manually, and it is necessary to ensure that each subsequent line of the applied solution overlaps the previous half. Immediately after applying the mortar, the formed surface is brought to the required forms manually by the rule ("Technology for plastering and puttying, using plastering (puttying) machines (stations) of German firms Putzmeicter, PTF, M-Tec", www.masterstroy.net.).

The disadvantage of all these units is that the application of the working mixture on the surface of the wall and the further refinement of the coating still remain completely manual operations. This requires additional time and additional labor, and the quality of coverage depends on the qualifications of the workers. The result is low productivity and a significant increase in the cost of work.

The objective of the proposed technical solution is to eliminate the above disadvantages.

The proposed technical solution, like the prototype, includes a machine for preparing a working mixture, equipped with a tank for supplying a solution, an electric drive, a compressor, a control panel, hoses for supplying water and a finished mixture and an electric cable mounted on a platform with wheels.

The technical essence of the invention lies in the fact that the end of the hose for supplying the working mixture is connected to the nozzle of the hollow rocker to distribute the solution, from the cavity of which a number of nozzles depart, the second ends of which are aligned and rigidly connected to the holes on the brackets mounted on the horizontal axis by means of bushings, this rule is attached to the brackets in the horizontal plane, and bushings with other brackets are mounted movably on the same axis, on which a restrictive rubber strip is fixed, a throat with a rule in the horizontal plane for spreading and pressing the mortar to the wall, and this whole structure has the ability to move in a vertical plane parallel to the wall by means of screw pairs connected to the axis, equipped with an electric drive and limit switches, mounted, in turn, on racks supported on self-aligning wheels, spacers for fixing on the wall, through bushings with anchors.

The device of the plaster-putty automated unit is illustrated by drawings, where Fig. 1 shows a diagram of the plaster-putty automated unit - side view; figure 2 presents the plastering and filler automatic unit, top view; figure 3 presents the site of applying the working mixture to the wall in section.

The stucco-filler automated unit includes a machine for preparing a working mixture mounted on a platform 1 (Fig. 1) with wheels, equipped with a tank 2 having a neck 3, for filling the tank 2 with mixture components, an electric motor 4, a compressor 5, a control panel 6, a hose water supply 7, with a valve 8, a hose 9 for supplying the finished mixture and an electric cable 10.

The end of the hose 9 (figure 2, 3) is connected to a mechanism equipped with a pipe 11 of the pressure distribution hollow beam 12, from the cavity of which a number of pipes 13 extend, the second ends of which are aligned and rigidly connected to the holes 14 (figure 3), in the brackets 15 connected to the sleeves 16, mounted on the axis 17. At the same time, the rule 19 is attached to the brackets 15, with the help of the fasteners 18, in the horizontal plane. On the same axis 17, the sleeves 21 are installed (FIG. 2), with the brackets 22 (FIG. 3 ), on which, using fasteners 23, a restrictive rubber strip of 24. I this design has the ability to move in a vertical plane parallel to the wall 25, through the bushings of the screw 26 (Fig.3), on the screws 27, pivotally mounted on a support 28 mounted on racks 29, supported by self-locking wheels 30. Racks 29 are fixed to the wall and to the floor with spacers 31 (FIG. 1), using screws 32, shims 33 and anchors 34.

Screw pairs 26 and 27 (figure 3) have the ability to contact with the limit switches 35 (figure 2), controlling the gear motors 36 (figure 1), through the cable 37. The working mixture 38 is applied to the wall 25, a layer 39, pumped compressed air compressor 5.

The process of plastering and filler automated unit is implemented as follows. Before starting work, the posts 29 are fixed in the wall 25 being processed (Fig. 1) using anchors 34 and adjusting washers 33. The spacer mechanism 31, using screws 32, presses the posts 29 against the wall with one end, and is fixed by the anchor 34 and the adjusting washer 33 with the other on the floor. Next, the pressure distribution hollow beam 12 (Fig.2, 3), by means of screw pairs 26 and 27 connected to the axis 17 and pivotally mounted on the lower supports 28, is transferred to the lowermost position, since the process of applying the stucco (putty) mixture 39 starts from the bottom . Further, in the neck 3 (FIG. 1) of the tank 2, for preparing and supplying the mixture, the required number of components of the stucco (putty) mixture is filled. The required amount of water is supplied through the hose 7 through the valve 8, using the control panel 6, the electric motor 4, the compressor 5, the process of preparing the plaster (putty) mixture is started. The finished mixture 38 through the hose 9, through the connecting pipe 11, enters the pressure distribution hollow beam 12 (figure 2). Further, through the nozzles 13, extending from the cavity of the rocker arm 12 through the holes 14 in the brackets 15, the mixture is pumped by compressed air by the compressor 5 and enters the neck formed between rule 19 and the restrictive rubber strip 24. The speed of the rule is selected taking into account the time of adherence of the mixture to the wall. The process of applying a plaster (putty) mixture 39 (figure 3) on the surface of the wall 25 starts from the bottom. The working mixture 38 entering the neck, formed between rule 19 and the restrictive rubber strip 24, moving from bottom to top, begins to lie on the wall 25 with an even layer 39. When the pressure distribution hollow beam 12 (figure 1) reaches a certain position, the limit switches 35, shutting off the flow of the mixture. Next, the compressor squeezes the rest of the mixture from the cavities of the hose, all nozzles and the neck, after which the mechanism is automatically turned off.

Using spacers 31 and 32, racks 29 are freed. The stucco-filler automated unit is brought to another wall and the process is repeated. Remaining untreated edges up to 10-12 cm around the perimeter of the wall are processed manually.

The positive aspects of the proposed technical solution are characterized by the following distinctive features.

- The sign "... the end of the hose for supplying the finished mixture, connected to the nozzle of the distribution hollow rocker arm, from the cavity of which a number of nozzles depart, the second ends of which are aligned and rigidly connected to the holes on the brackets mounted on the horizontal axis by bushings, while to the brackets in the horizontal a rule is attached to the plane, and bushings with other brackets are mounted on the same axis, on which a restrictive rubber strip is fixed, forming with the rule in the horizontal plane the throat inu for the distribution and pressing of the working mixture to the wall, and this whole structure has the ability to move in a vertical plane parallel to the wall by means of screw pairs connected to the axis, mounted, in turn, on racks ... ”, ensures accurate and high-quality application of the working mixture uniformly layer on the surface to be covered in one pass, in automatic mode, the surface of the putty layer, in comparison with the prototype, does not require re-processing. The technological process is carried out during the movement from the lowest point to the ceiling in automatic mode without human intervention, in comparison with the known advanced techniques 2.5-3.0 times faster.

- The sign "... racks based on self-mounted wheels, spacer mechanisms for fixing in the floor and on the wall through thrust washers with anchors" allows you to quickly mount and dismantle the mechanism and move it to another wall (or room). The time spent in comparison with known mechanisms is 4-5 times lower.

Thus, the proposed technical solution solves the technical problem.

The organization of the production of stucco-filler automated units does not present technical difficulties. The unit is equipped with a commercially available electric drive, compressor, control panel. The remaining components of the structure are manufactured on standard equipment and can be completed in any mechanical assembly unit.

Thus, the technical task posed is successful. The proposed stucco-filler automated unit, in comparison with the prototype and other technical solutions for a similar purpose, provides a high-quality monolithic smooth coating in one pass, with a productivity of 2.5-3.0 times faster, with minimal involvement of manual labor. And also the unit significantly accelerates the processes of installation, movement and dismantling during operation.
