A T-shaped composite wall with external thermal insulation and a key for energy dissipation and shock absorption with lead pipe and coarse sand and its method

Abstract

The invention discloses an external heat preservation T-shaped composite wall with lead pipe-coarse sand energy dissipation and seismic reduction keys and a construction method and belongs to the technical filed of building energy saving and seismic resistance. T-shaped composite wallboards are mainly composed of recycled concrete wallboard bodies, EPS heat preservation modules, PVC pipes and the lead pipe-coarse sand energy dissipation and seismic reduction keys. The lead pipe-coarse sand energy dissipation and seismic reduction keys are adopted to be fabricated in the PVC pipes of reserved holes in the upper and lower composite wallboards when the upper and lower composite wallboards are assembled. The T-shaped composite wall is provided with two seismic resistance defensive lines and has the good energy dissipation and seismic reduction functions. The disadvantage of the poor heat preservation property of a common concrete wall is changed, and meanwhile 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 external thermal insulation T-shaped composite wall with lead pipe-coarse sand energy-dissipating and shock-absorbing keys and a method thereof, belonging to the technical field of building energy-saving and anti-seismic technology. 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 major needs of national development. [0003] (2) The thermal insulation performance of t...
