Sandwich heat insulation l-shaped composite wall body with lead pipe-coarse sand energy dissipation and shock absorption keys and manufacturing method thereof

Abstract

The invention discloses a sandwich heat insulation l-shaped composite wall body with lead pipe-coarse sand energy dissipation and shock absorption reduction keys and a manufacturing method thereof, and belongs to the technical field of building energy saving and earthquake resistance. An l-shaped composite wall board mainly consists of l-shaped recycled concrete wall boards positioned at the two sides, a middle part sandwich EPS heat insulation module, round pipe fixing element with wings, the lead pipe-coarse sand energy dissipation and shock absorption reduction keys, lead pipes, coarse sand, zinc-plating thin steel plate cover plates and screw bolts. The lead pipe-coarse sand energy dissipation and shock absorption reduction keys are used, and are assembled in round holes of the round pipe fixing elements with the wings in upper and lower composite wall boards when the upper and lower composite wall boards are spliced; and the round pipe fixing elements with the wings which are arranged on the composite wall boards and are used for assembling the lead pipe-coarse sand energy dissipation and shock absorption reduction keys are simultaneously connected with the sandwich EPS heat insulation module and the recycled concrete wall boards positioned at the two sides. The sandwich heat insulation l-shaped composite wall body provided by the invention has the advantages that the defect of poor earthquake-resistant capability of the assembled concrete wall body is overcome; and an invented lead pipe-coarse sand shock absorption control device is organically combined with the novel structure assembled composite wall body, and the earthquake-resistant energy-saving and fireproof integral wall body is formed.

Description

technical field [0001] The invention relates to a sandwich thermal insulation inline 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] (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 ...
