Abstract

A composite concrete wall slab is composed of bar-mat reinforcement, concrete layer, and sound-isolating heat-insulating plate in said concrete layer. Said bar-mat reinforcement with rectangular cross-section consists of primary reinforcing mat and steel grids arranged at intervals. Its advantages are light weight, high strength, high resistance to fire and water, and high sound and heat insulation.

Description

technical field [0001] The present invention relates to a building element, in particular to a prefabricated concrete building element. Background technique [0002] In order to protect the environment and land resources, the use of clay bricks is gradually banned, and the demand for new wall materials is very urgent. The development trend of building wall materials is from block to plate, from heavy to light, and from single material to composite material. Existing prefabricated wall panels have certain weaknesses in various indicators such as weight, strength, stability, shrinkage rate, sound insulation, and thermal insulation, and it is difficult to meet the multifunctional and high performance requirements of modern buildings for wall materials. Contents of the invention [0003] The object of the present invention is to overcome the shortcomings of the above various structural systems, and provide a concrete composite wallboard with light weight, high strength, water...
