Description

Technical Field

[0001] The utility model relates to a plastering device for house construction, in particular to a plastering device for house construction, and belongs to the technical field of house plastering. Background Art

[0002] House wall plastering is an important project in building decoration. It is not only related to the beautiful appearance of the building, but also involves the protection and functionality of the building. It refers to the application of cement mortar, mixed mortar, and lime mortar surface on the wall. Indoor and outdoor wall plastering is a work after the completion of the building structure construction. Scientific plastering work can play the role of moisture-proof, weathering-proof, and heat-insulating, and prevent the walls of the building from being eroded by wind, rain, snow, etc. Plastering devices are usually used to plaster the walls of the house.

[0003] A plastering device for house construction is disclosed in the Chinese patent application publication specification CN220203309U. The cylinder of the device drives a support plate to move downward. When the rubber plate contacts the ground, it protects the support plate. The guide rod guides the support plate when it moves. This solves the technical problem in the prior art that when the stirring device in the device is used, the device vibrates, affecting the plastering effect.

[0004] However, during the implementation of the technical solution of the above patent, it is not possible to perform reciprocating smearing on the wall when plastering. Most of the existing plastering devices plaster the wall by simply moving the plastering board, and it is not possible to move the plastering board and perform reciprocating smearing on the wall while plastering. In wall plastering, reciprocating smearing is a key step. Compared with reciprocating smearing, simple smearing can make the mortar and the base layer in closer contact, and effectively remove the air in the mortar, reduce the generation of voids and bubbles, and thus improve the bonding effect. Therefore, the simple smearing method of the plastering device cannot guarantee the bonding effect between the mortar and the base layer. Utility Model Content
