Plate-structure fabricated building achieving force transmission and energy consumption by means of corner connection

Abstract

The invention provides a plate-structure fabricated building achieving force transmission and energy consumption by means of corner connection. The plate-structure fabricated building comprises wallboards and a floor slab, and upper-layer and lower-layer wallboards and the floor slab are connected through corner cover plates; energy consumption and shock absorption devices are arranged between thecorners of each wallboard and the corners of the floor slab, and the energy consumption and shock absorption devices penetrate through the upper-layer wallboards, the floor slab and the lower-layer wallboards through connecting parts; the wallboards are sandwich insulation boards, and an internal stress framework of each sandwich insulation board comprises reinforced concrete columns and steel-channel concrete superposed beams; and the floor slab is a sandwich floor slab. By means of the technical scheme, the same-layer wallboards which are connected at the corners are reliable in force transmission and safe in joint; the effects of shock absorption and connection of the upper-layer and lower-layer wallboards and the floor slab are achieved through the energy consumption and shock absorption devices, and the plate-structure fabricated building is safe, economical, energy-saving, capable of achieving shock absorption and convenient to assemble 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.

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
