Cast-in-place foam concrete wall

Abstract

The invention belongs to the technical field of building walls, and particularly relates to a cast-in-place foam concrete wall. The cast-in-place foam concrete wall comprises a lightgage steel joist,steel nets and connecting clamping parts. The lightgage steel joist comprises a keel side plate and a keel back plate, and inward side plate flange is arranged at the end, away from the keel back plate, of the keel side plate. Reinforcing ribs are arranged on the steel nets. Each connecting clamping part comprises a V-shaped clamping part main plate, a first clamping sheet, a second clamping sheetand a steel net clamping opening. The length of the connecting clamping parts is larger than the width of the lightgage steel joist, and the ends of the steel net clamping openings are provided withanti-falling hooks turned inwards. The first clamping sheets and the second clamping sheets are closely attached to the inner side of the side plate flanges, therefore, the connecting clamping sheetsare fixed to the lightgage steel joist, the steel net clamping openings are clamped outside the reinforcing ribs, and meanwhile the anti-falling hooks penetrate through meshes of the steel nets. According to the cast-in-place foam concrete wall, the steel nets are externally hung on the connecting clamping parts and are not directly in contact with the lightgage steel joist, a cold bridge and a heat bridge are prevented from being formed between the metal components, and the heat insulation, sound insulation, earthquake resisting and seepage resisting effects are good.

Description

technical field [0001] The invention belongs to the technical field of building wall structures, in particular to building walls with heat insulation, sound insulation, shock resistance and impermeability, and in particular to a cast-in-place foam concrete wall. Background technique [0002] Most of the existing walls in our country are still brick-concrete structures, which have poor thermal insulation, sound insulation and earthquake resistance, and the labor cost required for construction is high. With the rise of steel structure walls, polystyrene foam is filled in the walls Organic thermal insulation materials such as boards can play a certain role in thermal insulation and sound insulation, but their fire performance is poor, and they have fire safety hazards and are not resistant to aging. The cast-in-place foam concrete has good fire performance, fast construction of the wall, and low labor cost, but there is still a lot of room for improvement in the existing cast-i...
