Description

Technical Field

[0001] The invention relates to the technical field of steel structure assembly buildings, in particular to a modular steel structure house and an assembly process. Background Art

[0002] Traditional concrete structure house construction requires a lot of on-site pouring and long-term high-altitude work. Compared with concrete, steel structure has better tensile and earthquake resistance and short construction period. Modular prefabricated building system has great potential for factory and mechanization.

[0003] In the related technology, modular steel structure smart house is a movable and reusable building product, also known as modular house or container house. Steel structure modular smart house refers to the house body adopting steel frame structure system. The steel frame structure system is composed of frame beams and columns to resist vertical and horizontal loads. By dividing the components of the house into different functional modules, modular, standardized and universal production is used to achieve factory manufacturing. The house can be assembled on site anytime and anywhere, and the whole assembly process is more convenient and quick. With the advancement of technology and the increase in people's demand for modular houses, modular houses themselves are also developing, and modular houses with various functional designs have appeared on the market.

[0004] The existing modular houses have complex connection node structures and cumbersome construction procedures. In addition, the assembly accuracy of the steel structure skeleton is affected by the construction accuracy at the assembly site, which increases the difficulty of on-site construction and limits the large-scale application of modular houses. Therefore, most of the existing modular houses are single structures. The design of modular houses is generally a single room or only one floor. This type of modular house is difficult to accommodate a large number of people, so it also limits the development and application scenarios of modular houses. Summary of the invention

[0005] The object of the present invention is to provide a modular steel structure house and an assembly process to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solution: a modular steel structure house, comprising a plurality of modules A, wherein the modules A are arranged in a plurality of numbers, and the upper, lower, left and right adjacent modules A are assembled through nodes I and II;

[0007] Module B, wherein the module B is assembled with the module A via nodes I and II;

[0008] Module C, wherein the module C is assembled with the module A and the module B via the node I and the node II;

[0009] Module D, wherein the module D is assembled with the module C via nodes I and II;

[0010] The modules A, B, C and D are monomer frames of modular steel structure houses. The modules A, B, C and D are assembled horizontally and vertically based on nodes I and II to form modular steel structure houses, or the modules A, B, C and D are used separately. The modules are flexible and convenient to use and can meet different building requirements.

[0011] Furthermore, the modules A, B, C, and D are all assembled from a plurality of first steel components and second steel components. The steel has good plasticity and toughness and can absorb a large amount of energy, so that the modules A, B, C, and D exhibit good seismic performance. The steel structure has high strength and light weight, is easy to transport and install, and is suitable for large-span, high-height, and heavy-load-bearing structural buildings.

[0012] Furthermore, the module A is optionally equipped with a fence, and whether to use the fence can be determined based on demand. If the top space of the module A needs to be utilized, it is safer to stand on the module A.

[0013] Furthermore, a ladder frame is fixedly connected inside the module B. When the modules A, B, C and D are assembled into a multi-story building, the built-in ladder frame can be used to go upstairs without building stairs, and the building assembly speed is fast.

[0014] Furthermore, the node I includes a T-shaped plate, a first upper vertical plate, and a first lower vertical plate, and the first upper vertical plate and the first lower vertical plate are respectively fixedly connected to the upper and lower surfaces of the T-shaped plate, and the surfaces of the T-shaped plate, the first upper vertical plate, and the first lower vertical plate are all provided with a first elliptical bolt hole.

[0015] The node II includes a cross plate, a second upper vertical plate, and a second lower vertical plate, and the second upper vertical plate and the second lower vertical plate are respectively fixedly connected to the upper and lower surfaces of the cross plate, and the surfaces of the cross plate, the second upper vertical plate, and the second lower vertical plate are all provided with second elliptical bolt holes.

[0016] A first reinforcing rib is fixedly connected between the first upper vertical plate and the first lower vertical plate and the T-shaped plate, and a second reinforcing rib is fixedly connected between the second upper vertical plate and the second lower vertical plate and the cross plate;

[0017] By fixedly connecting the first upper vertical plate and the first lower vertical plate to the T-shaped plate, and fixedly connecting the second upper vertical plate and the second lower vertical plate to the cross plate, the stability of the node and the rigidity of the overall structure are enhanced. The provision of the first reinforcing rib and the second reinforcing rib can significantly improve the bearing capacity of the node, especially when subjected to shear force and bending moment. The design of the first elliptical bolt hole and the second elliptical bolt hole allows the bolt to adjust its position within a certain range, which helps to align the hole position during installation and improve the reliability and flexibility of the connection. The provision of the reinforcing rib helps to disperse stress and reduce local stress concentration, thereby improving the durability and service life of the steel structure house.

[0018] An assembly process for a modular steel structure house comprises the following steps:

[0019] Step 1, planning drawings: prepare the first steel member, second steel member, node I and node II that meet the requirements;

[0020] Step 2: prefabrication: select a number of first steel members, second steel members, nodes I and II and prefabricate them into a number of modules A, modules B, modules C and modules D;

[0021] Step 3, transportation: transport the spare first steel member, the second steel member, node I, node II, module A, module B, module C, and module D to the assembly site;

[0022] Step 4: Foundation treatment: Place modules A, B, C and D on a solid and level foundation and level them;

[0023] Step 5: Assembly: Based on step 1, several modules A, B, C, and D are assembled horizontally and vertically into a building.

[0024] When prefabricating module A, module B, module C, and module D based on the planning drawings, the bottom surface of module A or module C or module D assembled above module B is an open structure; the fence is fixedly connected to the surface of prefabricated module A based on the needs;

[0025] Prefabricated modules can be manufactured in advance in a factory environment, reducing on-site construction time and improving construction efficiency. Since most of the work is completed in the factory, the workload on site is reduced, thereby reducing the risk and complexity of on-site construction.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] (1) The building is divided into several modules A, B, C, and D according to different functions, allowing the building to change flexibly according to usage needs and adapt to different spatial needs and functional requirements.

[0028] (2) Modules A, B, C, and D can be freely combined horizontally and vertically, providing more design options, meeting diverse architectural forms, and flexibly adapting to a variety of space requirements.

[0029] (3) Assembling the building based on module A, module B, module C, and module D reduces the number of single components, can reduce material costs and manufacturing costs, and improve the efficiency of building assembly. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Example:

[0040] See also Figure 1-7 The present invention provides a technical solution: a modular steel structure house, including a module A100, wherein a plurality of modules A100 are provided, and the upper, lower, left, and right adjacent modules A100 are assembled through nodes I600 and II700, and the modules A100 can be used as a single building or connected to each other to meet the living requirements and storage needs of different numbers of people;

[0041] Module B200, the module B200 is assembled with module A100 through node I 600 and node II 700, and a ladder frame 201 is fixedly connected inside the module B200. When the whole building has more than two floors, the ladder frame 201 of the module B200 can be used to go up to the second floor. The modular ladder frame 201 reduces the workload of on-site construction because the ladder frame 201 as a part of the module B200 has been prefabricated in the factory, which speeds up the completion of the whole building;

[0042] Module C300, the module C300 is assembled with module A100 and module B200 via node I 600 and node II 700;

[0044] The modules A100, B200, C300 and D400 are monomer frames of modular steel structure houses. The modules A100, B200, C300 and D400 are assembled horizontally and vertically into modular steel structure houses based on nodes I600 and II700, or the modules A100, B200, C300 and D400 are used independently. The independent use is for single rooms, which is convenient for single use of the space inside the modules A100, B200, C300 and D400.
