Folding modular house

Abstract

The invention discloses a folding type modular house which comprises a house top plate, a house bottom plate, a longitudinal wall system, a transverse wall system and a flexible rotating mechanism. The longitudinal wall system sequentially comprises an upper fixed frame, a plurality of longitudinal wall rotating frames and a lower fixed frame from top to bottom; the transverse wall system is sequentially provided with top sealing angle steel, a transverse wall rotating frame and a transverse wall fixing frame from top to bottom; the frame is a rectangular closed steel frame body composed of a plurality of cross beams and a plurality of longitudinal columns, and the longitudinal columns are double-rectangular cold-bending steel pipes with gaps. Flexible rotating mechanisms are arranged between the adjacent cross beams of the two frames at the upper and lower positions and are fixedly connected with the two ends of the flexible rotating mechanisms respectively; when the house is assembled, T-shaped steel is inserted between the adjacent longitudinal columns of the two frames located at the upper position and the lower position, and the longitudinal columns are fixedly connected with the T-shaped steel. The house can be folded, the folding position is not prone to breakage when the house is assembled, and stability of the house is guaranteed.

Description

technical field [0001] The invention relates to the field of building houses, in particular to a foldable modular house. Background technique [0002] Folding houses are the living, living and working places of construction personnel, field survey personnel and scientific research personnel. They have the requirements of convenient construction, light weight, easy transportation and multiple turnover. The existing folding houses are not designed by structural engineering professionals, and there are the following safety problems in practice: [0003] (1) if figure 1 As shown, the existing folding houses rely on the hinges to realize the folding of the longitudinal walls, and the hinges bear the weight of the upper housing units during the use stage. In the metalworking design, the hinges are non-stressed components and are prone to damage after bearing the upper transfer load. Unable to achieve true turnover reuse, limited product life. [0004] (2) if figure 2 As shown...

AI Technical Summary

Problems solved by technology

[0003] (1) if figure 1 As shown, the existing folding houses rely on the hinges to realize the folding of the longitudinal walls, and the hinges bear the weight of the upper housing units during the use stage. In the metalworking design, the hinges are non-stressed components and are prone to damage after bearing the upper transfer load. Cannot achieve true turnaround reuse, limited product life

[0004] (2) if figure 2 As shown, due to the processing precision, there is a gap between the horizontal wall and the vertical wall or filled with waterproof rubber material, which cannot be completely fitted and connected reliably. The horizontal wall cannot support and restrain the vertical wall, and the vertical wall will fail when it is stressed. Stable, relying on the rotation of hinges, the stability of the structure will be destroyed

[0005] (3) The movable hinge of the longitudinal wall does not have the rotational bearing capacity in the closing direction of the hinge, and the hinge cannot resist the wall bending moment generated by the earthquake under the action of an earthquake, and will break, such as image 3 , Figure 4 As shown, causing the structure to collapse, that is, it does not have the level of seismic fortification
