Adjustable Serrated Wing Outside Corner Guards for Plastering Process

Abstract

The invention relates to an auxiliary tool for building construction, in particular to an adjustable sawtooth wing external corner guard plate used in the plastering process, including guard plate I and guard plate II; the overall shape of guard plate I and guard plate II is rectangular, wherein One long side is linear, and the other long side is serrated to form a sawtooth wing. The long side of the rectangle is not less than 2000mm, and the distance from the tooth bottom of the sawtooth wing to the straight long side is not less than 50mm; guard plate I and guard plate The straight long sides of II are fixed together, and the included angle between guard plate I and guard plate II is the same as the male angle; both guard plate I and guard plate II are provided with several installation holes. The side of the guard plate I and the guard plate II facing the wall is also provided with a number of gaskets I and II parallel to the guard plate I and the guard II and attached to the corresponding wall, and the gasket I and the gasket II It is connected with guard plate I and guard plate II through elastic members. The invention is convenient to use, can effectively prevent the external corner from being plastered by mistake, improves the construction quality and reduces the construction cost.

Description

technical field [0001] The invention relates to an auxiliary tool for building construction, in particular to an adjustable sawtooth wing external corner guard plate used in the plastering process. Background technique [0002] In the process of building construction, the external corners of the walls or pillars in the building need to be plastered with sand ash. The requirements for the sand ash used in the external corners are higher than those of the walls, so as to ensure that in the later operation process, the operator can reduce the amount of time spent on handling. When materials, equipment and other items collide with external corners, it may cause missing edges and corners, and avoid the impact on interior wall putty and paint construction, that is, possible multiple rework. The weight ratio of cement to coarse sand in sand ash for external corners required by relevant standards should be 1:2. The current method is to use the sand ash used on the wall first, that ...

Problems solved by technology

This method takes a long time and wastes raw materials

[0003] In actual operation, there are usually three problems. First, according to the above method, it is necessary to shovel off the plastered sand and ash, which wastes raw materials; The sand ash used for surface plastering is applied to the external corners, and the sand ash that does not meet the standard requirements at the external corners is no longer eradicated, resulting in the strength of the external corner sand ash not meeting the requirements of the relevant standards; The proportion of sand and gray in the male corner is not consistent, resulting in a loose combination of the two, which is prone to deformation and cracking
