Assembly type cast-in-place concrete exterior thermal insulation wall steel skeleton framework system and connecting piece

Abstract

The invention provides an assembly type cast-in-place concrete exterior thermal insulation wall steel skeleton framework system and a connecting piece. The system comprises a thermal insulation layer, a thin layer plastering protective layer, connecting bolts, trusses, horizontal steel bars and door and window frames. Thermal insulation plates are subjected to mutual tongue-and-groove inserted connection to form the thermal insulation layer and fixed to one side of the rigid trusses through connecting pieces. Construction parts can be assembled and formed on the ground and integrally hoisted, and the trusses can take the place of a part of bearing wall steel bars. The other sides of the trusses are connected through the horizontal steel bars which are connected with pre-cast vertical steel bars on the wall. Free-disassembly cement boards are then fixed to the trusses to form the system, and concrete of the bearing wall is poured in cavities of the system so that the system and the concrete of the bearing wall can be integrated to form an exterior thermal insulation concrete composite wall. According to the assembly type cast-in-place concrete exterior thermal insulation wall steel skeleton framework system and the connecting piece, the overall construction speed of an energy-saving building can be greatly improved, the construction safety risk is reduced, construction accuracy is effectively improved, the project quality is ensured, and meanwhile, a technical support is provided for building industrialization.

Description

technical field [0001] The invention relates to building materials, in particular to a complete set of technology for building energy-saving buildings that combines thermal insulation materials, wall structures and construction techniques. Background technique [0002] Insulation modules (boards) have been widely used in the insulation of building walls. The usual way of use is to paste the insulation modules (boards) on the outer surface of the wall that has been constructed to form an insulation layer, or to use insulation modules (boards) ) to form a formwork, and then pour concrete, so that the thermal insulation module (board) and concrete are integrated to form an external thermal insulation wall. However, the thermal insulation modules (boards) have to be spliced ​​on site, and the on-site construction material loss is large, and the ease of construction is poor, resulting in low overall construction speed of energy-saving buildings, long construction period, and high...

Problems solved by technology

However, the thermal insulation modules (boards) must be spliced ​​on site, and the on-site construction material loss is large, and the ease of construction is poor, resulting in low overall construction speed of energy-saving buildings, long construction period, and high construction costs.

[0003] During the 13th Five-Year Plan period, the country vigorously promoted prefabricated buildings, but there were very few prefabricated component production bases supplying prefabricated buildings. Compared with developed countries, the technical strength and level were still in the initial stage, and they were far from being able to fully enter the construction market. needs
