Sawtoothed wing external corner protective plate for plastering during construction

Abstract

The invention relates to an auxiliary tool for construction, in particular to a sawtoothed wing external corner protective plate for plastering during construction. The sawtoothed wing external corner protective plate is characterized by comprising a protective plate body I and a protective plate body II, wherein the protective plate body I and the protective plate body II are rectangular on the whole, one long side of each protective plate body is linear, the other long side of each protective plate body is sawtooth-shaped and forms a sawtoothed wing, the long sides of the rectangular protective plate bodies are not shorter than 2,000 mm, and the distance between the bottom of each tooth of the sawtoothed wing of each protective plate body and the linear long side is not shorter than 50mm; the linear long sides of the protective plate body I and the protective plate body II are fixed together, and an included angle formed by the protective plate body I and the protective plate body II is equal to an external corner of a building; a plurality of mounting holes are formed in each of the protective plate body I and the protective plate body II and used for connecting the protective plate bodies with a wall. The sawtoothed wing external corner protective plate has the advantages of convenience in use, capability of effectively preventing the external corner from being plastered mistakenly, improvement of construction quality and reduction of construction costs.

Description

technical field [0001] The invention relates to an auxiliary tool for building construction, in particular to a sawtooth wing external corner guard plate used in the plastering process of building construction. 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 wa...

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
