A cross-shaped sandwich thermal insulation composite wall with energy dissipation and shock absorption keys and its method

Abstract

The invention discloses a cross-shaped sandwich heat-preservation 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. The present invention adopts the lead pipe-coarse sand energy-dissipating and shock-absorbing key, which is assembled in the round hole of the winged circular tube fixing part in the composite wallboard when the upper and lower composite wallboards are assembled, and the composite wallboard is provided for assembling lead The winged round tube fixings of the tube-coarse sand energy dissipation and shock-absorbing key are simultaneously connected to the sandwich EPS insulation module and recycled concrete wall panels on both sides. The invention changes the shortcoming of poor thermal insulation of ordinary concrete walls, and at the same time overcomes the deficiency of poor anti-seismic ability of prefabricated concrete walls, and organically combines the invented lead pipe-coarse sand shock-absorbing control device with a newly constructed prefabricated composite wall , forming an integrated wall of earthquake resistance, energy saving and fire prevention. At the same time, the composite wall body uses recycled concrete materials, which is conducive to the development of construction waste resources and has obvious environmental benefits.

Description

technical field [0001] The invention relates to a cross-shaped sandwich heat-preservation composite wall with energy-dissipating and shock-absorbing keys. The energy-dissipating and shock-absorbing keys are composed of lead pipes and coarse sand, and belong to the technical field of energy-saving and earthquake-resistant buildings. 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. ...
