Description

Technical Field

[0001] This invention relates to the field of steel structure prefabricated building technology, specifically to a triangular modular steel structure house and its construction method. Background Technology

[0002] Modular construction is a building method that involves manufacturing prefabricated modules in a factory and then transporting these modules to the construction site for assembly into the final building. Compared to traditional construction methods, modular construction moves most of the construction process to the factory, including the prefabrication of building modules such as wall panels and floors. By prefabricating building modules in the factory, modular construction achieves a high degree of standardization and automation, significantly reducing on-site construction time. Module manufacturing in the factory takes place in a controlled environment, unaffected by external factors such as weather, ensuring consistent quality and high efficiency. Furthermore, factory and on-site construction can proceed concurrently; once the modules arrive at the site, only assembly is required, greatly reducing on-site labor needs and construction time, thereby accelerating the entire construction process and improving efficiency. Modular construction has begun to be applied to various building projects, including residential buildings, office buildings, schools, hospitals, and hotels, and is particularly suitable for projects requiring rapid construction.

[0003] Modular steel structure methods are widely used in single- and multi-story smart houses, cultural tourism cabins, and other buildings. As is characteristic of modular buildings, each module unit is a complete structural system composed of top beams, bottom beams, and columns. Adjacent modules transfer loads and coordinate deformations through corresponding connection nodes, allowing multiple units to form an integrated structure of a certain scale.

[0004] After the above installations form individual compartments, multiple compartments often need to be combined according to actual requirements to adapt to different scenarios due to functional needs. Conventional combination methods involve welding, bolting, and connecting with connectors at relevant locations on the modules. These methods have drawbacks, including complex connector installation, high risk of welding and hoisting coordination, large workload, difficult dismantling, lack of reusability after dismantling, and impact on usable facilities within the compartment during installation and dismantling. Summary of the Invention

[0005] The purpose of this invention is to provide a modular steel structure house with a triangular shape and its construction method, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a modular steel structure house in a triangular shape, comprising a cabin, wherein several cabins are arranged and assembled in a triangular shape, which is flexible and can be combined and adjusted as needed. The cabins can also be disassembled and reassembled, so that the cabins can be reused in different locations, thereby improving the sustainability of the cabins. The four corners of the cabins are equipped with assembly parts to make the cabins have an octagonal structure, thereby improving the stability of the cabin assembly.

[0007] The upper connector is triangular in shape and has protrusions. The upper connector is connected to two corners below the upper cabin.

[0008] The lower connector is triangular in shape and has a recess. The lower connector is connected to the corner above the lower compartment. The lower connector and the upper connector are detachable and connected.

[0009] Both the upper and lower connectors adopt a triangular design, which provides stability and can withstand greater pressure and tension, ensuring a stable connection.

[0010] The protrusion has a fixing component inside, and a spring is installed in the fixing component. The spring is connected to a telescopic component, and the telescopic component has an inclined surface that passes through the upper connecting component. The inner wall of the concave block has a slot corresponding to the telescopic component. The cooperation between the protrusion and the concave block can achieve precise positioning, ensuring that the upper and lower compartments can be accurately aligned when connected, thereby improving the accuracy and efficiency of the connection.

[0011] Furthermore, the assembly part of the cabin is provided with fittings. The upper and lower connectors are equipped with snap-fit ​​parts. The upper and lower connectors are connected to the cabin through snap-fit ​​parts and fittings. The fittings include tenons, the end of which is provided with a limiting groove and a first bolt hole. The snap-fit ​​parts include tenons, one end of which is provided with a limiting block and a second bolt hole. The design of the tenons and tenons makes it easy for the connectors to be aligned and connected with the fittings. The mortise and tenon connection structure has good stability and will not loosen due to the relative movement between the components.

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

[0013] A construction method for a modular steel structure house in a triangular shape includes the following steps:

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

[0015] Step 2, assembly: Based on the height of the cabin, install the upper connector to the assembly part of the upper cabin and the lower connector to the assembly part of the lower cabin. The tenon and the tenon slot are slidably connected. Use bolts to connect the tenon limiting block to the cabin.

[0016] Step 3: Assembly. After the cabins are transported to the site, they are positioned and placed. The upper connecting parts of the upper cabin are connected to the lower connecting parts of the lower cabin to complete the triangular assembly of the three cabins. The protrusions are installed into the concave blocks, and the concave blocks push the telescopic parts to move into the fixed parts. After the protrusions and concave blocks are inserted into place, the spring pushes the telescopic parts to lock into the slots so that the upper and lower cabins are locked together.

[0017] Step 4: Reinforcement. Use bolts to secure the upper and lower connectors.

[0018] It can be flexibly combined and expanded according to actual needs. Whether it is increasing the number of cabins or changing the layout, it can be done quickly to meet different usage scenarios and functional requirements.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] (1) After the upper and lower connecting parts are aligned and installed, the upper and lower compartments can be pre-fixed by the telescopic block. No lifting equipment is required for subsequent construction, which ensures the safety of construction operations to the greatest extent.

[0021] (2) The upper and lower connecting parts are connected to the cabin body through tenon grooves and bolts. The upper and lower connecting parts are connected to each other through expansion blocks and bolts. No welding is required throughout the process, which realizes rapid installation and disassembly. The parts can be reused and the installation and disassembly process has no impact on the cabin body and internal facilities.

[0022] (3) The three-character combination is stacked in space. The lower hollow part can be used as a garage and outdoor activity area, and the upper roof platform can be used as a viewing balcony, which enriches the use function of the cabin. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example:

[0034] Please see Figure 1-6 The present invention provides a technical solution: a modular steel structure house in a triangular shape, including a cabin 1, wherein several cabins 1 are arranged in a triangular shape and assembled. The four corners of the cabin 1 are equipped with assembly parts so that the cabin 1 has an octagonal structure. The triangular layout enhances the stability of the overall structure. The octagonal structure design makes the cabin 1 more evenly stressed and able to withstand a larger load. The modular design makes the house components easy to transport, only requires simple assembly on site, has a short construction cycle, and can quickly change construction sites.

[0035] Upper connector 2, which is triangular in shape and has protrusions 24, is connected to two corners below the upper cabin 1;

[0036] The lower connector 3 is triangular in shape and has a recess 34. The lower connector 3 is connected to the corner above the lower compartment 1. The lower connector 3 and the upper connector 2 are detachably connected, which facilitates the disassembly of the upper and lower compartments 1 and improves the flexibility and reusability of the modular compartment 1.

[0037] The protrusion 24 has a fixing member 242 inside, and a spring 243 is installed in the fixing member 242. The spring 243 is connected to a telescopic member 241, and the telescopic member 241 has an inclined surface and passes through the upper connecting member 2. The inner wall of the concave block 34 has a latch 38 corresponding to the telescopic member 241, which can lock and position the upper and lower compartments 1, ensuring that the connection between the compartments 1 is stable and reliable, and maintaining the integrity of the structure even when subjected to external forces. Due to the design of the spring 243 and the telescopic member 241, the telescopic member 241 has good elasticity and restoring ability. When it is necessary to disassemble the compartment 1, the locking state can be released with a simple operation.

[0038] In this embodiment, as Figure 4 As shown, the assembly part of the cabin 1 is equipped with an assembly fitting. The upper connector 2 and the lower connector 3 are equipped with snap-fit ​​fittings. The upper connector 2 and the lower connector 3 are connected to the cabin 1 through snap-fit ​​fittings and the assembly fitting. The assembly fitting includes a tenon groove 11. The end of the tenon groove 11 is provided with a limiting groove 12 and a first bolt hole 13. The snap-fit ​​fitting 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 1 to enhance the connection's ability to prevent it from falling off.

[0039] In this embodiment, as Figure 5 As shown, the surfaces of the protrusion 24 and the concave block 34 are respectively provided with three third bolt holes 25 and four bolt holes 35, as well as three first threaded holes 244 and two threaded holes 37. The protrusion 24 and the concave block 34 can be reinforced with six bolts to improve the assembly stability of the upper connector 2 and the lower connector 3 and ensure that the triangular-shaped cabin 1 will not loosen.

[0040] In this embodiment, as Figure 5 and Figure 6 As shown, the surface of the concave block 34 is provided with a control hole 36, and a control component is installed on the protrusion 24. The control component is placed in the control hole 36. The control component controls the telescopic component 241 to separate from the bayonet 38. When disassembling the cabin 1, the control component can easily separate the telescopic component 241 from the bayonet 38, thereby separating the upper connecting component 2 and the lower connecting component 3.

[0041] In this embodiment, as Figure 6 As shown, the control component includes a connecting rod 245 and a toggle block 246. The connecting rod 245 is fixedly connected to the telescopic component 241. When the toggle block 246 is moved, the toggle block 246 controls the telescopic component 241 to retract into the fixed component 242 through the connecting rod 245, making the operation simple.

[0042] A construction method for a modular steel structure house in a triangular shape includes the following steps:

[0043] Step 1: Planning. Select a flat and solid site and plan the placement, quantity, and number of layers of the cabin 1 on the ground.

[0044] Step 2, assembly: Based on the floor height of the cabin 1, install the upper connector 2 to the assembly part of the upper cabin 1, and install the lower connector 3 to the assembly part of the lower cabin 1. The tenon 21 and the tenon groove 11 are slidably inserted into each other, and the tenon limiting block 22 is connected to the cabin 1 using bolts.

[0045] Step 3: Assembly. After the cabin 1 is transported to the site, it is positioned and placed. The upper connecting piece 2 of the upper cabin 1 is connected to the lower connecting piece 3 of the lower cabin 1 to complete the triangular assembly of the three cabins 1. The protrusion 24 is installed into the concave block 34. The concave block 34 pushes the telescopic piece 241 to move into the fixing piece 242. After the protrusion 24 and the concave block 34 are inserted into place, the spring 243 pushes the telescopic piece 241 to lock into the slot 38 so that the upper cabin 1 and the lower cabin 1 are locked together. Bolts are used to reinforce the concave block 34 and the protrusion 24.

[0046] When it is necessary to disassemble the cabin 1, first unscrew the bolts fixing the concave block 34 and the protruding block 24, then connect the crane to the cabin 1, then reach into the control hole 36 to move the toggle block 246. After the toggle block 246 controls the telescopic component 241 to separate from the bayonet 38, the crane lifts the cabin 1 and successfully disassembles the upper cabin 1, completing the disassembly of the triangular cabin 1.

[0047] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
