Technical Field
The utility model belongs to the technical field of the building construction equipment, concretely relates to cement patching machine suitable for construction of building interior outer wall.
Background
At present, the traditional mixed mortar plastering construction process is adopted for the rough decoration surface layer of the inner walls of most residential buildings all over the country, and although the traditional construction process is mature, the quality problems of hollowing, cracking and the like of the plastering surface layer are caused by construction management, construction operation, materials, worker construction level and other aspects in the construction process. At present, the wall surface in the building field is mostly filled and built by aerated bricks, and the aerated bricks become energy-saving, environment-friendly and wall bodies of the buildings in China due to the advantages of energy conservation, land conservation, little pollution and the like, and are widely used on civil high-rise buildings and industrial plants. However, the raw materials of the aerated brick mainly comprise cement, lime, sand, fly ash and the like, and the aerated brick has the characteristics of large water-cement ratio, more cementing materials, high water absorption rate, high shrinkage deformation and the like, is easy to absorb a large amount of water during plastering due to high water absorption performance of the aerated brick, easily causes hollowing, cracking and the like on the plastered wall surface, and seriously affects the wall surface quality. Some techniques are improved aiming at the traditional process, for example, an externally hung wall surface mortar dauber with the publication number of CN 108343218A, a crane tower system function drives a crane boom function system, an electric spiral shotcrete machine is arranged in the crane boom, concrete sprayed by the spiral shotcrete machine is coated on the wall surface, and a spring dauber carried by the shotcrete machine is used for daubing cement mortar on the wall surface, which is an improvement technique of the traditional plastering process.
The existing improved plastering process is a construction process for directly spraying mortar to an operation surface by adopting an automatic mortar spraying machine or a semi-automatic mortar spraying machine, and the concrete spraying technology has the characteristics of saving cement and sand, saving labor, improving construction efficiency, reducing engineering cost and the like, and has a very wide application prospect. However, the existing spray construction mode is usually operated by manually holding a spray gun, and although the spray construction forms a certain industrial standard, the adhesion of the slurry on a base layer is difficult to ensure by the existing slurry and construction method, and the engineering quality of the spray construction is seriously influenced. Because the construction management, the construction operation, the construction level of workers and the like need to be controlled or improved in the construction process, manual guniting is time-consuming and labor-consuming, the construction cost is increased, meanwhile, the construction period can be delayed, and the construction period is contrary to the original intention of guniting construction. For example, a construction method for one-step molding of gypsum mortar spraying and plastering of an indoor wall surface machine with publication number CN107035085A is that firstly, grid cloth is pasted at the joint of different materials according to requirements, plaster cakes and screeds are constructed by using gypsum mortar, and corner protection construction is carried out on external corner parts of doors, window frames and the like by using cement mortar or mixed mortar; and then, using a shotcrete machine to rapidly move gypsum mortar back and forth along the horizontal direction at a constant speed, directly spraying the gypsum mortar on the structural wall from top to bottom, immediately troweling the gypsum mortar from bottom to top along the mark ribs by using an aluminum alloy scraper after spraying, and when the gypsum mortar is slightly solidified, checking the flatness of the wall by using a guiding rule, and repairing the high and low positions. The problems that the mobility is poor when the spray gun is adjusted, the guniting is not uniform, the mortar falling is serious, the material receiving needs to be carried out through plastic cloth, the guniting pressure is insufficient due to the large angle of the spray gun, the compactness and the homogeneity performance of the guniting cannot be kept consistent and the like exist.
