Cross-shaped sandwich thermal-insulating composite wall provided with energy-dissipation and damping keys and manufacturing method

Abstract

The invention discloses a cross-shaped sandwich thermal-insulating composite wall provided with energy-dissipation and damping keys and a manufacturing method, and belongs to the technical field of energy conservation and earthquake resistance of buildings. The lead pipe-coarse sand energy-dissipation and damping keys are adopted and assembled in round holes in winged round pipe fixing pieces in composite wall boards during splicing of the upper and lower composite wall boards. The winged round pipe fixing pieces, used for assembling the lead pipe-coarse sand energy-dissipation and damping keys, of the composite wall boards are simultaneously connected with a sandwich EPS thermal-insulating module and the recycled concrete wall boards on the two sides. 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 a cross-shaped sandwich thermal insulation composite wall with energy dissipation and shock absorption keys. The energy dissipation and shock absorption keys are composed of lead pipes and coarse sand, and belong to the technical field of energy-saving and seismic-resistant buildings. Background technique [0002] (1) my country has a vast territory and a large population. Most of the buildings are in earthquake areas. Some of them are self-built. Due to the lack of earthquake resistance knowledge, the construction technology cannot meet the basic requirements of earthquake resistance, and the earthquake resistance capacity is very weak. The earthquakes in Tangshan, Wenchuan, Yushu, and Ya'an caused severe damage and collapse of houses. Research and develop low-cost, easy-to-operate, and practical assembly-type seismic and energy-saving integrated structures to meet the major needs of national development. [0003] (2) The thermal in...
