Fabricated bidirectional composite wall board provided with keyway-shaped grooves and construction method of fabricated bidirectional composite wall board

Abstract

A fabricated bidirectional composite wall board provided with keyway-shaped grooves comprises an inner layer wall board and an outer layer wall board. The inner layer wall board is mainly composed ofconcrete lattices and autoclaved aerated concrete building blocks, and the concrete lattices are filled with the autoclaved aerated concrete building blocks; the outer layer wall board is mainly composed of a concrete protective layer on the outer side and an XPS thermal insulation board on the inner side; and the inner layer wall board and the outer layer wall board are connected through thermomass MS / MC connecting pieces. The fabricated bidirectional composite wall board provided with the keyway-shaped grooves is characterized in that the keyway-shaped grooves are formed in the side faces ofthe inner layer wall board and the outer layer wall board at equal intervals and used for injecting of cast-in-place concrete when the adjacent wall boards are connected, the keyway-shaped grooves are each of a trapezoid table structure, and the bottom surface of each keyway-shaped groove is an opening end. The invention further provides a construction method of the fabricated bidirectional composite wall board provided with the keyway-shaped grooves. The fabricated bidirectional composite wall board is environmentally friendly and good in shock resistance, and not only can the production efficiency be improved, but also the production and construction cost of components is further reduced.

Description

technical field [0001] The invention belongs to the field of building technology, and relates to an assembled composite wallboard integrating heat preservation and load bearing, in particular to an assembled bidirectional composite wallboard with a keyway-shaped groove and a construction method thereof. Background technique [0002] my country is still in the period of large-scale capital construction. New construction and demolition of old buildings have produced a large amount of construction waste. At present, the disposal methods of construction waste are mainly landfill and stacking. The rate of resource recycling is very low, and a large amount of construction waste is filled. Burying and stacking not only invade and destroy the land, but also seriously pollute the environment. A large number of old buildings in urban and rural areas in my country are mainly masonry structures or mixed structures, and waste bricks account for a large proportion of construction waste, bu...

[0004] At present, most prefabricated wall panels are made of concrete products. Not only is the structure heavy, it is not convenient for transportation and hoisting, but also a large amount of concrete is used, which requires a large amount of excavation of sand and gravel resources, pollutes the environment, and does not really achieve green environmental protection of prefabricated buildings.

[0006] At the same time, some existing composite walls cannot achieve the integration of heat preservation and load bearing

In addition, the concrete compactness of the post-cast connecting columns between the wall panels is not good, and the side connections of the wall panels are not tight, which affects the overall stability and earthquake resistance
