Reinforced concrete passive thermal insulation wall with fixing pieces

Abstract

A reinforced concrete passive thermal insulation wall body with fixing pieces comprises a reinforced concrete wall body internally provided with steel wire meshes in advance, a thermal insulation layer, a concrete protection layer internally provided with double-layer steel wire meshes in advance, thermal insulation connecting pieces and structural connecting pieces. The sub-connecting piece comprises a connecting cylinder and a net limiting plate which is convexly arranged at one end of the connecting cylinder; the locking plate comprises a locking hole and a plurality of locking claws which are obliquely arranged; after the connecting cylinder sequentially penetrates through the double-layer steel wire mesh and the heat preservation layer from outside to inside, the mesh limiting plate makes contact with the anti-cracking mesh in the double-layer steel wire mesh, and the clamping plate is fixedly arranged at the other end, protruding out of the heat preservation layer, of the connecting cylinder and makes contact with the inner surface of the heat preservation layer at the same time. After the structural connecting piece sequentially penetrates through the steel wire mesh, the cavity and the lock hole from inside to outside, the movable end of the lock claw abuts against the outer wall, protruding out of the lock hole, of the structural connecting piece to limit the structural connecting piece in the direction from outside to inside, integrated connection of the structural wall body, the heat preservation layer and the concrete protection layer is achieved, and the falling-off phenomenon is avoided.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation of building exterior walls, and in particular relates to a reinforced concrete passive thermal insulation wall with fixing parts. Background technique [0002] As we all know, China has a vast territory and a significant monsoon climate. It has the characteristics of high temperature and rain in summer, cold and little rain in winter, and the high temperature period is consistent with the rainy period. Due to the cold climate in winter and high temperature in summer, most buildings generally require thermal insulation structures outside the walls. , to achieve thermal insulation inside the building in winter and cool inside the building in summer. The usual way of installing the thermal insulation structure is to use glue to connect the thermal insulation layer with the outer wall of the building. For different buildings and different insulation grade requirements, the thickness of the...
