Sandwiched heat preservation L-shaped composite wall body with lead pipe-coarse sand energy-dissipation damping keys and construction method

Abstract

The invention discloses a sandwiched heat preservation L-shaped composite wall body with lead pipe-coarse sand energy-dissipation damping keys and a construction method and belongs to the technical field of building energy saving and earthquake resistance. According to the sandwiched heat preservation L-shaped composite wall body with the lead pipe-coarse sand energy-dissipation damping keys and the construction method, the lead pipe-coarse sand energy-dissipation damping keys are adopted and assembled in circular holes of winged circular pipe fixing pieces in an upper composite wall plate and a lower composite wall plate when the upper composite wall plate and the lower composite wall plate are spliced, and the winged circular pipe fixing pieces arranged on the composite wall plates and used for assembling the lead pipe-coarse sand energy-dissipation damping keys are simultaneously connected with a sandwiched EPS heat preservation module and reclaimed concrete wall plates on the two sides. The L-shaped composite wall body is provided with two earthquake fortification lines and thus has good energy-dissipation damping performance. The disadvantage that an ordinary concrete wall body is poor in heat preservation is changed, and meanwhile the defect that a fabricated concrete wall body is poor in earthquake resistance is overcome. A lead pipe-coarse sand damping control device and a fabricated composite wall body are organically combined, and thus the earthquake-resistance, energy conversation and fireproofness integrated wall body is formed. Meanwhile, the composite wall body utilizes a reclaimed concrete material, development of building garbage recycling is facilitated, and environmental benefits are obvious.

Description

technical field [0001] The invention relates to a sandwich heat-preservation L-shaped composite wall with lead pipe-coarse sand energy-dissipating and shock-absorbing keys and a method thereof, belonging to the field of building energy-saving and earthquake-resistant technologies. Background technique [0002] my country has a vast territory and a large population. Most of the buildings are located in the earthquake zone, some of which are mainly self-built. Due to the lack of knowledge about earthquake resistance, the construction technology cannot meet the basic requirements of 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] The insulation performance of the walls of the house ...
