Prefabricated coal gangue thermal insulation concrete shear wall plate

Abstract

A prefabricated coal gangue heat preservation concrete shear wall plate is formed by pouring coal gangue concrete, longitudinal steel bars and stirrups, and square holes are formed in the shear wall in the height direction. The axes of the square holes in the coal gangue concrete hollow shear wall plate are consistent with the height direction, and the square holes are evenly distributed in the width direction. The square holes are filled with the heat preservation cotton, and the heat preservation effect can be achieved. The coal gangue concrete is adopted to replace common concrete, waste of coal gangue resources can be avoided, harm to the environment due to random stacking of coal gangue can be relieved, huge economic benefits and environmental benefits are created, and meanwhile the coal gangue concrete has great practical significance in resource recycling and environmental protection. And unified development of resource saving and environment friendliness is realized. According to the prefabricated coal gangue heat preservation concrete shear wall plate, a building heat preservation system and a structure have the same service life, the secondary heat preservation decoration cost of the structure is saved, the total cost is reduced, and good application prospects and economic values are achieved.

Description

technical field [0001] The invention relates to the technical field of coal gangue concrete shear wall panels, in particular to a prefabricated coal gangue thermal insulation concrete shear wall panel. Background technique [0002] Coal gangue is a dark gray rock with lower carbon content and harder than coal. It is a solid waste produced in the process of coal mining and coal washing. Coal gangue, which is an industrial waste, is often piled up into coal gangue mountains, which not only occupies a large amount of agricultural land, but also pollutes the environment, and even produces harmful gases when spontaneously igniting, endangering human health. For this reason, coal gangue is developed to replace ordinary sand and gravel Coarse aggregates are made into concrete, which promotes the resource utilization of coal-based solid waste. Compared with the frame structure, the shear wall structure has high rigidity and small lateral movement. Compared with the frame structure,...
