Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building engineering, in particular to a foldable building structure framework. BACKGROUND

[0002] The building structure framework is an important component of building engineering, which bears the weight of wallboard, roof, floor, and is affected by wind load, earthquake, etc., and is directly related to the use function of the house. However, the existing building structure framework has many deficiencies:

[0003] The traditional building structure framework usually has scattered components, complex construction process, long construction period, high requirement for on-site construction equipment, and high technical requirement for construction personnel. Most of the structure frameworks cannot be repeatedly disassembled and used after being built.

[0004] Most of the existing prefabricated building structure frameworks adopt a fixed integrated mode, which reduces the on-site construction time, but at the same time increases the limitation of the building, for example, the internal use space of the created building is usually small, and the later expansion is not strong. It can only be customized for specific use scenarios, and the product cannot be flexibly adjusted after leaving the factory according to the actual use scenario. The prefabricated building with high integration consumes more space during transportation, and the corresponding built building space is smaller with the same loading space, which consumes more transportation resources.

[0005] Therefore, it is of great significance to develop a scalable / foldable building framework. SUMMARY

[0006] The purpose of the present application is to provide a scalable and foldable building structure framework, characterized by: a plurality of foldable structural unit A combined together, the foldable structural unit A is composed of a lower rectangular frame structure, a lower C-shaped structure, a vertical foldable structure, an upper rectangular frame structure, and an upper C-shaped structure.

[0007] The vertical foldable 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.

[0008] The lower rectangular frame structure is a frame structure composed of two longitudinal sliding rail beams I and two connecting beams I.

[0009] The lower C-shaped structure is connected by two longitudinal sliding rails I and one connecting beam II.

[0010] The lower rectangular frame structure is equipped with a lower C-shaped structure at each end.

[0011] The upper rectangular frame structure is a frame structure composed of two longitudinal slide rail beams II and two connecting beams II.

[0012] The upper C-shaped structure is connected by two longitudinal slide rails II and a connecting beam III.

[0013] The upper rectangular frame structure is equipped with an upper C-shaped structure at each end. The two longitudinal slide rail beams II of the upper C-shaped structure are connected to the longitudinal slide rail beams II of the upper rectangular frame structure, so that the upper rectangular frame structure and the two upper C-shaped structures form a frame structure, which is referred to as a lower frame structure.

[0014] One upper frame structure and one lower frame structure are equipped with two vertical folding structures. The vertical folding structures are located between the upper frame structure and the lower frame structure. The end of the upper connecting beam not connected to the loose-leaf hinge mechanism is hinged to the upper C-shaped structure of the upper frame structure, and the end of the lower connecting beam not connected to the loose-leaf hinge mechanism is hinged to the lower C-shaped structure of the lower frame structure.

[0015] When folded, the upper connecting beam and the lower connecting beam are in a horizontal state. When unfolded, the upper connecting beam and the lower connecting beam are in a vertical state.

[0016] Further, in the lower rectangular frame structure, the lower end of the longitudinal slide rail beam I is connected to four support connecting plates I.

[0017] Further, in the lower C-shaped structure, the connecting beam II is connected to two longitudinal slide rails I at the connecting beam II. The upper and lower ends of the column foot are connected to the upper and lower support connecting plates, respectively.

[0018] Further, in the upper rectangular frame structure, the lower end of the longitudinal slide rail beam II is connected to four support connecting plates II.

[0019] Further, in the upper C-shaped structure, the connecting beam III is connected to two longitudinal slide rails II at the connecting beam III. The lower end of the corner foot is connected to the support connecting plate.

[0020] Further, in the vertical folding structure, the upper and lower ends of the upper connecting beam are respectively the upper and lower connecting end plates I.

[0021] Further, the upper and lower ends of the lower connecting beam are respectively the upper and lower connecting end plates II.

[0022] Further, the loose-leaf hinge mechanism includes two hinge plates and several flat-leaf loose-leaf hinges. 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 several flat-leaf loose-leaf hinges.

[0023] Further, the upper connecting beam is hinged with the upper C-shaped structural member, and the upper connecting beam is hinged with the corner foot through the flat-leaf loose-leaf hinge II.

[0024] Further, the lower connecting beam is hinged with the lower C-shaped structural member, and the column foot is hinged with the lower connecting beam through the flat-leaf loose-leaf hinge I.

[0025] The technical effects of the present application are self-evident:

[0026] 1. Efficient space utilization: various structural components are compactly and orderly arranged to achieve maximum transportation efficiency with minimum space occupation.

[0027] 2. High building area after structure expansion: through the innovative folding and unfolding mechanism, the originally compact structural components can be rapidly expanded into spacious building space in a short time.

[0028] 3. Shortening of construction time: during construction, the prefabricated structural components and efficient assembly method greatly simplify the construction process and significantly shorten the construction time.

[0029] 4. Reducing dependence on large equipment: compared with traditional construction methods, this technology reduces the dependence on large equipment during construction. Due to the lightweight and standardized design of the structural components, they can be completed by lighter lifting equipment and manual assistance. BRIEF DESCRIPTION OF DRAWINGS
