Description

Thin plastering construction device for building block wall surface

Technical Field

The utility model relates to the technical field of decoration construction, in particular to a thin plastering construction device for a wall surface of a building block.

Background

In recent years, along with the application of high-precision aerated concrete blocks in the field of buildings, the precision of a main structure of the building is higher and higher, and the high-precision aerated concrete blocks have great influence on the indoor fine decoration of the building. As a matching process, the high-precision aerated concrete block wall surface thin plastering technology can effectively overcome the problems of long plastering construction time and multiple consumables in the traditional plastering, and has the advantages of high flatness of a wall surface plastering layer and difficult pulverization and falling. The existing technical system for high-precision masonry thin plastering construction mainly comprises six processes of construction preparation, mortar preparation, elastic line drawing, dotting and rib punching, layered plastering and repeated surface collecting. After the dotting and punching operation is carried out, the ribs provide specific reference parameters for the thin plastering operation, and the plastering between the ribs can ensure that the whole plaster layer reaches certain verticality and flatness. However, layered plastering still requires larger workload of operators, and manual errors are inevitably generated in the operation, so that problems are brought to subsequent surface collecting operation, and the labor intensity of the workers is increased.

The effect of layered plastering directly influences the verticality and flatness of the plastering wall surface, and the quality of the layered plastering wall surface can obviously influence the quality of the surface collecting work. CN216142348U describes a portable plastering device, which realizes plastering at different heights through a movable storage cavity, and designs an opening in the storage cavity and cooperates with a putty knife to realize plastering operation in the moving process. However, in actual operation, the hand wheel is manually rotated to lift the height of the storage box, and because the storage box is directly contacted with the cross beam, when the storage box is horizontally moved each time, larger resistance is required to be overcome, so that the physical consumption and the labor intensity of workers are increased intangibly. In addition, when the thin plastering operation is performed on the high-precision block wall, because the thickness of the rib punching strips is not neglected, plastering is performed between the two rib punching strips, and the space left by the rib punching strips at the yin and yang angle positions is narrower, the device is blocked and cannot be completely attached to the wall, so that the flexibility of a thin plastering device is ensured, the quality is ensured, and the work efficiency is improved.
