A panel structure prefabricated house using corner connections for force transmission and energy dissipation

Abstract

The present invention provides a prefabricated house with panel structure utilizing corner connections for force transmission and energy consumption, which includes wall panels and floor panels, and the upper and lower layer wall panels and floor panels are connected by corner cover panels; the wall panels An energy-dissipating and shock-absorbing device is provided between the corner and the corner of the floor; the energy-dissipating and shock-absorbing device passes through the upper wall, the floor and the lower wall through connectors; the wall is a sandwich insulation board, and the The internal stress frame of the sandwich insulation board includes reinforced concrete columns and channel-steel-concrete composite beams; the floor is a sandwich floor. Adopting the technical solution of the present invention, the force transmission of the same-layer wallboards connected at the corners is reliable, and the joints are safe; and the functions of shock absorption and connection of the upper and lower wallboards and floor slabs are realized through the energy dissipation and shock-absorbing device, which is safe, economical, energy-saving, and energy-saving. Shock, easy to install and disassemble.

Description

technical field [0001] The invention belongs to the technical field of building structure engineering, and in particular relates to a plate-structure assembled house using corner connections for force transmission and energy consumption. Background technique [0002] At present, in the field of industrial and civil construction, prefabricated houses with panel structures have broad development prospects because of their rapid installation and disassembly. [0003] Existing technology constantly has research result to release to prefabricated house. As introduced in the patent CN 107989172 A, the corner fittings in the light-weight plate-structure house are composed of a perforated backing plate, a positioning pin, and a perforated end plate at the end of the column, and the frame welded with steel components is used as the The light body wall panels of the steel skeleton are assembled into a panel structure house, that is, a light body panel structure house is formed. Thre...

AI Technical Summary

Problems solved by technology

The corner fittings are connected by full bolts, etc., and the bolts are easy to loosen under the action of an earthquake, causing hidden dangers in the structure

[0006] (2) Most of the prefabricated corner fittings are connected by steel components, which has obvious cold and heat bridge effect; and due to the assembly, there are gaps between each plate structure, resulting in poor thermal insulation performance of prefabricated house nodes, which is not conducive to environmental protection and energy saving

[0007] (3) The effect of energy dissipation and shock absorption measures for most container module buildings is not significant, and there is still a head-on phenomenon between the double pyramid and the corner pieces, and there are still sudden impact consequences when the displacement reaches a certain level under the earthquake

However, these energy-consuming devices are not only complex in structure, but also uneconomical for prefabricated house structures
