Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building engineering, especially relates to a folding building structure framework. BACKGROUND

[0002] The building structure framework, as an indispensable part of building engineering, bears the weight of wallboard, roof and floor, and needs to cope with the influence of wind load, earthquake and other natural forces, and its performance is directly related to the actual use efficiency of the house. However, in the current design and application of building structure framework, there are still a series of problems to be solved:

[0003] Traditional building framework components are fragmented, complex and long in construction, high in technical requirements for equipment and construction personnel, and often cannot be reused after construction. In comparison, the prefabricated building structure framework adopts a fixed integrated mode, which significantly shortens the on-site construction time. However, this mode also brings limitations: the internal space of the building is usually small, the later expansion is poor, and it can only be customized for specific scenarios, and it is difficult to adjust the layout flexibly after leaving the factory. In addition, the highly integrated prefabricated building occupies a large space during transportation, making the corresponding building space smaller for the same loading space, thereby increasing the consumption of transportation resources.

[0004] Therefore, it is of great significance to develop a foldable building framework. SUMMARY

[0005] The utility model aims at providing a foldable building structure framework, characterized by: comprising a plurality of combined folding structure unit B, the folding structure unit B is composed of a lower rectangular frame structure, two vertical folding structure, an upper rectangular frame structure. The reserved space in the framework can pre-integrate the floor and roof panel.

[0006] The vertical folding structure includes an upper connecting beam, a lower connecting beam and a loose-leaf hinge mechanism. The two upper connecting beams and the two lower connecting beams are hinged through the loose-leaf hinge mechanism to form a V-shaped opening and closing frame structure.

[0007] The lower rectangular frame structure is a frame structure composed of two longitudinal beams i and two connecting beams i.

[0008] The upper rectangular frame structure is a frame structure composed of two longitudinal beams ii and two connecting beams ii.

[0009] The vertical folding structure is located between the lower rectangular frame structure and the upper rectangular frame structure. The end of the upper connecting beam not connected with the loose-leaf hinge mechanism is hinged with the upper rectangular frame structure, and the end of the lower connecting beam not connected with the loose-leaf hinge mechanism is hinged with the lower rectangular frame structure.

[0010] When folded, the upper connecting beams and the lower connecting beams are in a horizontal state. When unfolded, the upper connecting beams and the lower connecting beams are in a vertical state.

[0011] Further, in the lower rectangular frame structure, the connecting position of the longitudinal beam i and the connecting beam i is a column foot i. The upper and lower ends of the column foot i are connected with an upper support connecting plate i and a lower support connecting plate i respectively.

[0012] Further, in the upper rectangular frame structure, the connecting position of the longitudinal beam ii and the connecting beam ii is an angle foot i. The lower end of the angle foot i is connected with a support connecting plate i, or the lower end of the angle foot i is connected with a support connecting plate i and the upper end is connected with a support connecting plate ii.

[0013] Further, in the vertical folding structure, the upper and lower ends of the upper connecting beam are an upper connecting end plate i and a lower connecting end plate i respectively.

[0014] Further, the upper and lower ends of the lower connecting beam are an upper connecting end plate ii and a lower connecting end plate ii respectively.

[0015] Further, the hinge mechanism includes two hinge plates and a plurality of flat hinge leaves. The lower connecting end plates i of the two upper connecting beams are connected to the same hinge plate, and the lower connecting end plates ii of the two lower connecting beams are connected to the same hinge plate. The two hinge plates are connected together through a plurality of flat hinge leaves.

[0016] Further, the upper connecting beam is hinged with the upper rectangular frame structure through the flat hinge leaf ii, which hingingly connects the upper connecting beam with the angle foot i.

[0017] Further, the lower connecting beam is hinged with the lower rectangular frame structure through the flat hinge leaf i, which hingingly connects the column foot i with the lower connecting beam.

[0018] The technical effects brought by the utility model are obvious:

[0019] 1. Efficient use of space: through ingenious design and compact layout, the structural components are arranged in order, thereby realizing the maximization of transportation efficiency while occupying the minimum space.

[0020] 2. Broad area after building unfolding: with the aid of innovative folding and unfolding technology, the originally compact structural components can be rapidly and substantially unfolded to form a wide building space, meeting diversified use requirements.

[0021] 3. Shortening of construction period: the combination of prefabricated structural components and efficient assembly mode greatly simplifies the cumbersome construction steps, thereby effectively shortening the overall construction time and improving engineering efficiency.

[0022] 4. Reduction of dependence on heavy equipment: Compared with traditional construction modes, the utility model reduces the dependence on large equipment through lightweight and standardized design of structural components. This means that lightweight hoisting equipment and manual assistance can be used more in the construction process, achieving flexible and efficient construction. BRIEF DESCRIPTION OF DRAWINGS
