A step-by-step construction method for the base layer of stadium stand tread decoration

Abstract

The invention relates to stand construction methods, particularly to a stepwise construction method of decorative base layers of a stadium stand tread. The method mainly comprises the following steps of painting a layer of adhesion agent on the base layers on side surfaces and external corners, plastering the side surfaces and the external corners and beveling the external corners twice; maintaining the side surfaces and the external corners; surface-processing the stadium stand tread and applying a layer of adhesion agent on the stadium stand tread; plastering the stadium stand tread with fine stone concrete and meanwhile sloping the stadium stand tread; maintaining the stadium stand tread. According to the stepwise construction method of the decorative base layers of the stadium stand tread, dropping and hollowing of the fine stone concrete leveling layer of the stadium stand tread and the mortar leveling layer of the side surfaces can be effectively avoided, and meanwhile, the problem of cracking of the external corners due to different contractility and hydroscopicity of mortar and concrete can be solved.

Description

technical field [0001] The invention relates to a construction method of a stand, in particular to a step-by-step construction method for a tread decoration base layer of a stadium stand. Background technique [0002] The stand design of the stadium is very important, and the plane shape of the stadium has an important relationship with the combination of the stands. For example, the handover between the outer wall of a circular gymnasium and the stands will result in a lot of waste of space, which requires a coordinated handling of the handover relationship between the stands and the outer walls. Generally speaking, small and medium-sized gymnasiums do not adopt circular schemes in terms of sight, acoustics and other functional requirements, but use polygons and ellipses instead, so that the stands will be more advantageous in terms of plane processing. like figure 1 As shown, it is a plan view of an elliptical stand 10, and the stands 10 around it all have a certain arc....

AI Technical Summary

Problems solved by technology

With the above-mentioned stand structure, the fine stone concrete leveling layer on the tread 101 and the mortar leveling layer on the side 102 are prone to fall off and hollowing

Because the side 102 mortar leveling layer and the tread 101 fine stone leveling layer are poured successively, the shrinkage and water absorption of the two materials are different, and shrinkage cracks are likely to appear at the junction, resulting in cracking problems
