Description

Technical Field

[0001] The invention relates to the technical field of steel structure assembled buildings, and in particular to a Chinese-shaped modular steel structure house and a construction method thereof. Background Art

[0002] Modular buildings are a construction method that produces prefabricated modules in factories and transports them to the construction site to be assembled into the final building. Compared with traditional construction methods, modular buildings move most of the construction process to the factory, including the prefabrication of building modules such as wall panels and floors. Modular buildings achieve a high degree of standardization and automation by prefabricating building modules in the factory, greatly shortening the on-site construction time. The module manufacturing in the factory is carried out in a controlled environment, unaffected by external factors such as weather, ensuring stable quality and high efficiency. At the same time, factory and on-site construction can be carried out in parallel, and the modules only need to be assembled after being transported to the construction site, which greatly reduces the labor demand and construction time on site, thereby speeding up the entire construction process and improving construction efficiency. Modular buildings have begun to be used in various construction projects such as residential, office buildings, schools, hospitals and hotels, especially those that need to be built quickly.

[0003] The modular method of steel structure is widely used in single- and multi-story smart houses, cultural and tourism cabins and other buildings. From the characteristics of modular buildings, it can be seen that each module unit is a complete structural system composed of top beams, bottom beams and columns. Adjacent modules transfer loads and coordinate deformation through corresponding connection nodes, so that multiple units form an overall structure of a certain scale.

[0004] After the above installation is completed to form a single cabin, it is often necessary to combine multiple cabins according to actual requirements due to the use function and other requirements to adapt to different scenarios. The conventional combination method is to weld, bolt, connect connectors, etc. at the relevant positions of the modules. The above methods have the disadvantages of complex installation process of connectors, high risk factor of welding and hoisting collaborative work, large workload, difficult dismantling, complex dismantling without reusability, and installation and dismantling affecting the facilities used in the cabin. Summary of the invention

[0005] The object of the present invention is to provide a modular steel structure house in the shape of a triangle and a construction method thereof, so as to solve the problems raised in the above-mentioned background technology.

[0012] Furthermore, a control hole is provided on the surface of the concave block, and a control member is installed on the convex block. The control member is placed in the control hole, and the control member controls the telescopic member to separate from the bayonet. The control member includes a connecting rod and a toggle block. The connecting rod is fixedly connected to the telescopic member. When splitting, the toggle block controls the telescopic member to separate from the bayonet, and the operation of splitting the cabin is simple.

[0013] A construction method of a Chinese-shaped modular steel structure house comprises the following steps:

[0014] Step 1: Planning: Select a flat and solid site and plan the placement, quantity and number of cabins on the ground;

[0015] Step 2: assembling: based on the floor height of the cabin, the upper connecting piece is installed to the assembly part of the upper cabin, the lower connecting piece is installed to the assembly part of the lower cabin, the tenon and the tenon groove are slidably plugged, and the tenon limit block is connected to the cabin with bolts;

[0016] Step 3: Assemble. After the cabins are transported to the site, they are positioned and placed. The upper connecting piece of the upper cabin is connected to the lower connecting piece of the lower cabin to complete the three cabins in a herringbone shape. The protrusion is installed in the concave block, and the concave block pushes the telescopic piece to move toward the fixed piece.

The Chinese-shaped layout enhances the stability of the overall structure, and the octagonal structure design makes the cabin 1 more evenly stressed and can withstand a larger load. The modular design makes the house components easy to transport, and only simple assembly is required on site, the construction period is short, and the construction site can be quickly changed;

[0035] An upper connecting member 2, which is triangular in shape and has a protrusion 24, and is connected to two corners below the upper cabin 1;

[0036] The lower connecting member 3 is triangular and has a concave block 34. The lower connecting member 3 is connected to the corner above the lower cabin 1. The lower connecting member 3 and the upper connecting member 2 are detachably connected, which facilitates the separation of the upper and lower cabins 1, thereby improving the flexibility and reusability of the modular cabin 1;

The spring 243 is connected to a telescopic part 241, and the telescopic part 241 has an inclined surface and passes through the upper connecting part 2. The inner wall of the concave block 34 is provided with a bayonet 38 corresponding to the telescopic part 241, which can lock and position the upper and lower cabins 1, ensuring that the connection between the cabins 1 is stable and reliable, and the integrity of the structure can be maintained even when subjected to external forces. Due to the design of the spring 243 and the telescopic part 241, the telescopic part 241 has good elasticity and reset ability. When the cabin 1 needs to be disassembled, the locking state can be released with a simple operation.

[0038] In this embodiment, if Figure 4 As shown, the assembly part of the cabin body 1 is provided with an assembly part, the upper connecting part 2 and the lower connecting part 3 are provided with a clamping part, the upper connecting part 2 and the lower connecting part 3 are connected to the cabin body 1 through the clamping part and the assembly part, the assembly part includes a mortise groove 11, the end of the mortise groove 11 is provided with a limiting groove 12 and a first bolt hole 13, the clamping part includes a tenon 21, one end of the tenon 21 is provided with a limiting block and a second bolt hole 23, two bolts are used to fix the tenon 21 and the cabin body 1, so as to enhance the anti-falling ability of the connection.
