External corner guard board with adjustable sawtooth wings and used for plastering process

Abstract

The invention relates to an auxiliary tool for building construction, in particular to an external corner guard board with adjustable sawtooth wings and used for a plastering process. The guard board comprises a guard board body I and a guard board body II. The guard board body I and the guard board body II are integrally rectangular. One long edge of each guard board body is in a linear shape, and the other long edge of each guar board body is in a sawtooth shape and forms the corresponding sawtooth wing. The long edge of each rectangle is larger than or equal to 2000 mm, and the distance between the tooth bottoms of the sawtooth wings and the linear long edges is larger than or equal to 50 mm. The linear long edges of the guard board body I and the guard board body II are fixed together. The inclined angle between the guard board body I and the guard board body II is equal to the external corner. Both the guard board body I and the guard board body II are provided with a plurality of mounting holes. The sides, facing walls, of the guard board body I and the guard board body II are further provided with a plurality of spacers I and spacers II, wherein the spacers I and the spacers II are parallel to the guard board body I and the guard board body II and attached to the corresponding walls. The spaces I and the spacers II are connected with the guard board body I and the guard board body II through elastic components. The external corner guard board is convenient to use and capable of preventing the external corner from being plastered by accident effectively, improving construction quality and lowering 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, tha...

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
