Abstract

A prefabricated concrete sandwich insulation wall board connecting piece and a connecting method belong to the technical field of construction engineering. The connecting piece of the invention is simple to process and manufacture, and the production cost is low. The fiber tube has good thermal resistance, which is favorable for thermal insulation of a wall body. The connecting piece with tubularsection has high flexural rigidity, and strength of the fiber tube is high. The outer and inner holes of the connecting piece help increase the embedding ability of the connecting piece in the concrete, and an outer acanthus-leaf connection reinforcement and an inner acanthus-leaf connection reinforcement are arranged to better enhance the embedding ability of the connecting piece in the concrete.Through the connecting piece for connecting outer and inner walls of the prefabricated concrete sandwich insulation wall board, the connection strength and rigidity of the outer and inner walls of the prefabricated concrete sandwich insulation wall board are good, and connection reliability and construction quality can be ensured. The connecting method is simple to operate and convenient to implement, can help improve production efficiency and reduce production cost so as to reduce the cost of building construction.

Description

technical field [0001] The invention belongs to the technical field of construction engineering and relates to a prefabricated concrete building, in particular to a prefabricated concrete sandwich insulation wall panel connector and a connecting method. Background technique [0002] At present, the connectors of precast concrete sandwich insulation wall panels are mainly fiber plastic (FRP) connectors. The fiber plastic (FRP) connector is a key component connecting the inner and outer concrete slabs of the precast concrete sandwich insulation wall, and it mainly bears the pull-out load and the shear load in the wall. According to different structural forms, FRP connectors can be divided into three types: plate type, rod type and lattice type. As early as the end of the 1980s, the United States, Australia and other countries have carried out the research and development and application of FRP connectors. CGS Corporation of Australia, Aslan Corporation of the United States, ...
