Fabricated external heat preservation L-shaped composite wall body with energy-dissipation damping keys and construction method thereof

Abstract

The invention discloses a fabricated external heat preservation L-shaped composite wall body with energy-dissipation damping keys and a construction method thereof and belongs to the technical field of building energy saving and earthquake resistance. According to the fabricated external heat preservation L-shaped composite wall body with the energy-dissipation damping keys and the construction method thereof, the lead pipe-coarse sand energy-dissipation damping keys are adopted and assembled in PVC pipes of reserved holes in upper composite wall plates and lower composite wall plates when the upper composite wall plates and the lower composite wall plates are spliced. Two earthquake fortification lines are arranged on the L-shaped composite wall body, and good energy-dissipation damping performance is achieved. 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 capacity 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-saving and fireproof integrated wall body is formed. Meanwhile, according to the composite wall body, reclaimed concrete materials are utilized, thus building garbage reclamation development is facilitated, and environmental benefits are obvious.

Description

technical field [0001] The invention relates to an assembled external thermal insulation L-shaped composite wall with energy-dissipating and shock-absorbing keys and a method thereof, belonging to the technical field of building energy-saving and shock-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 insulation performance of the house wall is po...
