Prefabricated external thermal-insulation Z-shaped composite wall provided with lead pipe-coarse sand energy-dissipation and damping keys and manufacturing method

Abstract

The invention discloses a prefabricated external thermal-insulation Z-shaped composite wall provided with lead pipe-coarse sand energy-dissipation and damping keys and a manufacturing method, and belongs to the technical field of energy conservation and earthquake resistance of buildings. The Z-shaped composite wall is mainly composed of a recycled concrete wall board, an EPS thermal-insulation module, PVC pipes and the lead pipe-coarse sand energy-dissipation and damping keys. The lead pipe-coarse sand energy-dissipation and damping keys are adopted and assembled into the PVC pipes in holes reserved in the upper and lower composite wall boards when the upper and lower composite wall board are spliced. The Z-shaped composite wall is provided with two defense lines for earthquake resistance and has good energy-dissipation and damping performance. By adoption of the composite wall and the manufacturing method, the defect that the thermal insulation performance of an ordinary concrete wall is poor is overcome, and the shortcoming that the earthquake resistance of a prefabricated concrete wall is poor is overcome at the same time; and lead pipe-coarse sand damping control devices and the prefabricated composite wall of a novel structure are organically combined, and the earthquake-resisting, energy-saving and fireproof integrated wall is formed. Meanwhile, the composite wall adopts a recycled concrete material, building waste recycling development is facilitated, and the environment benefits are obvious.

Description

technical field [0001] The invention relates to an assembled external thermal insulation Z-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 perfor...
