Abstract

The invention discloses an external-heat-preservation type cross-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. The cross-shaped composite wall body is mainly composed of reclaimed concrete wall plates, an EPS heat preservation module, PVC pipes and the lead pipe-coarse sand energy-dissipation damping keys. According to the external-heat-preservation type cross-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 the PVC pipes of reserved holes 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. The cross-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 of a novel structure 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 cross-shaped composite wall with an external thermal insulation type and lead pipe-coarse sand energy dissipation and shock absorption keys and a method thereof, and belongs to the technical field of building energy conservation 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-seismic and energy-saving integrated structures meet the major needs of national development. [0003] (2) The thermal insul...
