Z-shaped composite wall with sandwich insulation function and damping key and construction method

Abstract

The invention discloses a Z-shaped composite wall with a sandwich insulation function and a damping key and a construction method, and belongs to the technical field of building energy conservation and seismic resistance. According to the Z-shaped composite wall and the construction method, the lead tube-coarse sand energy dissipation and vibration reduction key is adopted for being assembled in a circular hole of a winged circular tube fixing piece in an upper composite wall panel and a lower composite wall panel when the upper composite wall panel and the lower composite wall panel are assembled, and meanwhile the winged circular tube fixing piece which is arranged on the composite panels and used for assembling the lead tube-coarse sand energy dissipation and vibration reduction key is connected with a sandwich EPS insulation module and recycled concrete wall panels on the two sides. The Z-shaped composite wall is provided with two seismic fortification lines and has the good energy dissipation and vibration reduction properties. Accordingly, the defect that a concrete wall is poor in insulation is changed, the defect that an assembly type concrete wall is poor in seismic capacity is overcome, a lead tube-coarse sand energy dissipation and vibration reduction control device and the newly constructed assembly type composite wall are organically combined, and an anti-seismic, energy-saving and fireproofing integrated wall is formed. Meanwhile, the composite wall utilizes recycled concrete materials, building waste resource development is promoted, and the environmental benefit is obvious.

Description

technical field [0001] The invention relates to a Z-shaped composite wall with sandwich insulation and shock-absorbing keys. The shock-absorbing key is a lead pipe-coarse sand energy-dissipating and shock-absorbing key. In particular, it also relates to an assembled sandwich insulation Z-shaped composite wall and its method. The utility model belongs to the technical field of building energy saving and earthquake resistance. 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-s...
