Fabricated sandwich heat preservation T-shaped composite wall with energy dissipation and seismic reduction keys and construction method

Abstract

The invention discloses a fabricated sandwiched heat preservation T-shaped composite wall with energy dissipation and seismic reduction keys and a construction method and belongs to the technical field of building energy saving and seismic resistance. The lead pipe-coarse sand energy dissipation and seismic reduction keys are adopted to be fabricated in circular holes of circular pipe fixing pieces with wings in upper and lower composite wallboards when the upper and lower composite wallboards are assembled. The circular pipe fixing pieces with the wings which are arranged in the composite wallboards and used for fabricating the lead pipe-coarse sand energy dissipation and seismic reduction keys are simultaneously connected with sandwich EPS heat preservation modules and recycled concrete wallboard bodies on the two sides. The T-shaped composite wall is provided with two seismic resistance defensive lines and has good energy dissipation and seismic reduction functions. The defect of the poor seismic resistance capacity of a fabricated concrete wall is overcome. A lead pipe-coarse sand seismic reduction control device and the novel constructed fabricated composite wall are combined organically to form the seismic resistance, energy saving and fireproofing integrated wall. Meanwhile, according to the composite wall, recycled concrete materials are utilized, thus recycling development of building garbage is facilitated, and environmental benefits are obvious.

Description

technical field [0001] The invention relates to an assembled sandwich thermal insulation T-shaped composite wall with energy-dissipating and shock-absorbing keys and a method thereof. The energy-dissipating and shock-absorbing keys are a structure composed of lead pipes and coarse sand, and belong to the technical field of energy-saving and earthquake-resistant buildings. Background technique [0002] (1) my country has a vast territory and a large population. Most of the buildings are located in the earthquake zone, and some of them are mainly self-built. Due to the lack of knowledge about earthquake resistance, the construction technology cannot meet the basic requirements for earthquake resistance, and the earthquake resistance is very weak. The Tangshan, Wenchuan, Yushu, and Ya'an earthquakes caused severe house damage and collapse. Research and development of low-cost, easy-to-operate, and practical assembled anti-seismic and energy-saving integrated structures meet the...
