FRP connecting piece of prefabricated heat preservation wall body

Abstract

The invention belongs to the technical field of civil engineering, and concretely relates to an FRP connecting piece of a prefabricated heat preservation wall body. The connecting piece consists of an FRP connection board and a plastic socket ring and is characterized in that the FRP connection board is fabricated by a pultrusion technique, a fiber layering is compositely laid by adopting unidirectional coarse roving, continuous fibrofelt and positive / negative degree multiple axial directional cloth. After pultrusion, the FRP connection board is cut by fixed length to fabricate an FRP connection board single piece, and mechanical processing equipment is used for cutting one or more than one anchoring rabbet at the end part of the connection board, and finally the melt ABS plastic is cast around the FRP connection board by a casting technique to obtain the finished product of the FRP connecting piece of the prefabricated heat preservation wall body; wherein, the connection board component in the connecting piece is used for connecting the concrete wall pieces at the two sides of a heat preservation board, while the ABS plastic socket ring is used for fixing the position of the connecting piece during concrete casting. The invention realizes a novel connecting system with an integral structural function, has the advantages of low heat conductivity coefficient, good corrosive nature, simple and convenient construction and the like, and has relatively extensive application prospect in the field of civil engineering.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a prefabricated thermal insulation wall FRP (fiber reinforced plastic) connector. Background technique [0002] my country's traditional wall materials are mainly small block materials such as clay bricks and hollow blocks, which have many shortcomings such as excessive structural weight, slow construction speed, low work efficiency, and unstable construction quality. The energy consumption of buildings built with traditional wall materials is about three times that of developed countries with similar climates. In recent years, my country has gradually begun to adopt building insulation systems with organic foam materials as insulation components in buildings. In this system, organic foam materials are mostly attached to the enclosure wall, the construction is more complicated, and the fire performance is poor. It is not conducive to the sustainable d...

Problems solved by technology

Most of the existing prefabricated thermal insulation walls (such as EVG-3D wall panels developed by Austrian EVG company) are connected by metal lattice bars, which are prone to thermal bridges at the joints, and may cause potential safety hazards due to corrosion of the joints
