Description

Technical Field

[0001] The present application relates to the field of building construction engineering, and in particular to a modular low-rise assembled special-shaped column steel structure house system. Background Art

[0002] While traditional cast-in-place concrete construction remains dominant in the construction industry, it is increasingly facing limitations due to issues such as long construction periods and severe environmental pollution. With the widespread adoption of green building concepts and technological advancements, prefabricated buildings, with their advantages of rapid construction, high quality control, environmental protection, and energy conservation, are becoming a new trend in the construction industry. Prefabricated steel structures are particularly popular in the low-rise building market due to their excellent seismic resistance, high strength, and lightweight construction.

[0003] Traditional steel structure houses require the assembly of various special-shaped steels at the construction site. After the special-shaped steel columns are processed in the factory according to the design requirements, they are transported to the construction site. Then the construction workers assemble the special-shaped steel columns one by one to complete the assembly of the entire steel structure. However, due to the large number of special-shaped steel columns required for the house, it still takes a long time to assemble at the construction site. In addition, the construction time is further affected in rainy and snowy weather, resulting in limited assembly efficiency of traditional steel structure houses, which needs to be further improved. Summary of the Invention

[0004] In order to alleviate the problem of long assembly time of traditional steel structure houses, the present application provides a modular low-rise assembled special-shaped column steel structure house system.

[0005] This application provides a modular low-rise assembled special-shaped column steel structure house system, which adopts the following technical solutions:

[0006] A modular low-rise assembled special-shaped column steel structure house system, including

[0007] The base structure is laid on the foundation and is used to be fixedly connected to the ground;

[0008] The main load-bearing structure includes a plurality of I-shaped top beams, each of which is hinged with a supporting steel column at both ends. Each of the supporting steel columns can be rotated toward the direction close to the I-shaped top beam. The supporting steel column can be rotated to be perpendicular to the I-shaped top beam to support the I-shaped top beam, and two adjacent I-shaped top beams are abutted and fixed;

[0009] The wall panel structure is arranged outside a plurality of supporting steel columns;

[0010] The floor panel structure is arranged on the upper parts of the plurality of I-shaped top beams.

[0011] By adopting the above technical solution, before assembling the house, the I-shaped top beam and the supporting steel columns are prefabricated and assembled into one in the factory, and then the two supporting steel columns are rotated so that the two supporting steel columns are in contact with the I-shaped top beam and remain parallel to the length direction of the I-shaped top beam, thereby facilitating the transportation of the I-shaped top beam; after being transported to the construction site, the supporting steel columns are rotated to be perpendicular to the I-shaped top beam, and then the two supporting steel columns support the I-shaped top beam. After fixing the two adjacent I-shaped top beams according to the design requirements, the assembly of the main load-bearing structure of the house can be completed quickly, thereby improving the efficiency of house assembly on the construction site while facilitating transportation.

[0012] Preferably, the foundation structure includes two base support beams, which are arranged parallel to the length direction of the house to be built. The bottom of each base support beam is fixedly connected to a plurality of foundation columns buried in the foundation. Each base support beam is provided with a placement groove, which is opened along the base support beam, and the supporting steel column can slide in the placement groove.

[0013] By adopting the above technical solution and utilizing the placement grooves on the base support beam, when assembling the main load-bearing structure at the construction site, the I-shaped top beam is hoisted so that the two support steel columns hinged on the I-shaped top beam are respectively inserted into the two placement grooves to keep the I-shaped top beam stable. The I-shaped top beam can be pushed to slide along the two placement grooves to the predetermined position, thereby further improving the convenience of assembling the house.

[0014] Preferably, each of the base support beams is provided with a plurality of positioning grooves, which are opened along the length direction of the base support beam, and each of the positioning grooves is opened on the bottom surface of the placement groove. A supporting assembly is provided in each of the positioning grooves, and the supporting assembly is used to support the supporting steel column that is slidably connected in the placement groove. When the supporting steel column moves to the plug-in position, the positioning groove at the corresponding position releases the supporting steel column.

[0015] By adopting the above technical solution, the setting of the positioning groove can ensure that the supporting steel column can move to the preset position. At the same time, in order to prevent other positioning grooves from blocking the sliding of the supporting steel column, the top support assembly can temporarily support the supporting steel column through other positioning grooves.

[0016] Preferably, each group of the support assemblies includes a screw and a support plate, the screw is passed through the side of the base beam, the screw is threadedly connected to the base beam, the support plate is slidably connected in the positioning groove, and the screw is rotatably connected to the support plate to drive the support plate to slide.

[0017] By adopting the above technical solution, the top support plate can be driven to move by rotating the screw. When temporary support is required for the supporting steel column, the screw is rotated to push the top support plate to the middle of the positioning groove, so as to provide temporary support for the sliding of the supporting steel column. When the supporting steel column needs to be clamped and positioned, the screw is rotated to drive the top support plate to one side of the positioning groove, so that the supporting steel column can be clamped into its corresponding positioning groove, and then the screw is rotated again to push the top support plate to press the supporting steel column tightly.

[0018] Preferably, each of the I-shaped top beams is provided with a locking assembly, and the locking assembly includes a lifting rod and two plug-in rods. The lifting rod is passed through the I-shaped top beam, and the lifting rod is slidably connected to the I-shaped top beam. The two plug-in rods are fixedly connected to the lifting rod. Plug-in holes are provided on the two supporting steel columns connected to the I-shaped top beam. The two plug-in rods are arranged in a one-to-one correspondence with the two plug-in holes, and the plug-in rods are used to be inserted into the corresponding plug-in holes.

[0019] By adopting the above technical solution, before transporting the I-shaped top beam, the two supporting steel columns are rotated to retract the two supporting steel columns, and the lifting rod is pushed to insert the two connecting rods into the locking holes on the two supporting steel columns respectively, so that the two supporting steel columns can be locked to ensure the stability of the supporting steel columns during transportation.

[0020] Preferably, a spring is provided between the lifting rod and the I-shaped top beam, and the spring applies a pulling force to the lifting rod so that the plug rod is inserted into the plug hole.

[0021] By adopting the above technical solution, the tension of the spring is used to ensure the stability of the plug-in rod after insertion, thereby preventing it from falling off during transportation.

[0022] Preferably, two connecting pipes are provided on the I-shaped top beam, and the two connecting pipes are respectively arranged in one-to-one correspondence with the two supporting steel columns connected to the I-shaped top beam. The two connecting pipes pass through the I-shaped top beam and are inserted into the corresponding supporting steel columns.

[0023] By adopting the above technical solution, after the supporting steel column is unfolded, the connecting pipe is pushed into the supporting steel column, so that the supporting steel column and the I-shaped top beam can be locked and fixed, ensuring the supporting strength of the supporting steel column to the I-shaped top beam.

[0024] Preferably, the I-shaped top beam includes a solid part located in the middle and hollow parts located on both sides, a drainage hole is opened on the top of the solid part, the drainage hole is connected with the hollow part, and the hollow part is connected with the interior of the supporting steel column through the connecting hole opened by the connecting pipe; the lifting rod is passed through the solid part, the lifting rod is slidably connected to the solid part, and a blocking plate is fixedly connected to the top of the lifting rod, and the spring applies tension to the blocking plate so that the blocking plate blocks the drainage hole.

[0025] By adopting the above technical solution, after the floor panel structure is laid on multiple I-shaped top beams, due to the overall steel frame structure, the drainage performance of the floor panel is poor. By utilizing the setting of the drainage holes, when water is accidentally spilled or cleaned on the floor panel of the house, the sealing plate can be pulled upwards to open the drainage holes. Then the water can flow along the drainage holes into the hollow part of the I-shaped top beam, and then into the supporting steel column, and then discharged through the placement groove.

[0026] Preferably, the connecting pipes located in the same row are commonly connected with two-layer base support beams, and the two-layer base support beams are used to support the I-shaped top beams of the next layer.

[0027] By adopting the above technical solution, multiple connecting pipes are used to support and fix the second-floor base support beam, which not only maintains the plug-in stability of the connecting pipes, but also ensures the connection strength between the second-floor base support beam and the first-floor I-shaped top beam.

[0028] In summary, this application has at least the following beneficial technical effects:

[0029] 1. By hingedly connecting the I-shaped top beam and the supporting steel columns, the two supporting steel columns can be aligned with the I-shaped top beam and kept parallel to the length of the I-shaped top beam when transporting it. This facilitates the transportation of the I-shaped top beam. After transporting it to the construction site, the supporting steel columns are rotated to be perpendicular to the I-shaped top beam, and then the two supporting steel columns support the I-shaped top beam. After fixing the two adjacent I-shaped top beams according to the design requirements, the main load-bearing structure of the house can be quickly assembled, improving the efficiency of house assembly on the construction site while facilitating transportation.

[0030] 2. By utilizing the placement slots on the base support beam, when assembling the main load-bearing structure at the construction site, the two hinged support steel columns on the I-shaped top beam are inserted into the two placement slots respectively to keep the I-shaped top beam stable. The I-shaped top beam can then be pushed to slide along the two placement slots to the predetermined position, further improving the convenience of house assembly.

[0031] 3. By utilizing the hollow part of the I-shaped steel beam, when the floor panel of the house is accidentally spilled or cleaned, the blocking plate can be pulled upwards to open the drainage hole. Then the water can flow along the drainage hole into the hollow part of the I-shaped top beam, and then into the supporting steel column, and then be discharged through the placement groove.

DETAILED DESCRIPTION

[0042] The following is combined with Figure 1-9 This application is described in further detail.

[0043] The embodiments of the present application disclose a modular low-rise assembled special-shaped column steel structure house system.

[0044] Reference Figure 1 and Figure 2A modular low-rise prefabricated steel structure with special-shaped columns includes a foundation structure 100, a main load-bearing structure 200, a wall panel structure 300, and a floor panel structure 400. The foundation structure 100 is laid on the ground layer and serves as the foundation of the entire steel structure house, responsible for connecting and fixing it to the ground. The main load-bearing structure 200, composed of special-shaped steel columns, serves as the main load-bearing structure of the house, bearing the main load of the entire house. The wall structure serves as the wall panel of the house, and the floor panel structure 400 supports the floor of the house. The entire house system is assembled and constructed by assembling multiple modules separately.

[0045] Reference Figure 2 and Figure 3 The foundation structure 100 includes a plurality of foundation columns 110 buried in the foundation. The plurality of foundation columns 110 are divided into two groups. The two groups of foundation columns 110 are arranged in parallel along the length direction of the house to be built. The plurality of foundation columns 110 in the same group are arranged at intervals along the length direction of the house to be built. The plurality of foundation columns 110 in the same group are fixedly connected with a base support beam 120. The base support beam 120 is fixedly connected to each foundation column 110 by bolts. The base support beam 120 can be buried in the foundation. The base support beam 120 is used to support the main load-bearing structure 200, and the main load-bearing structure 200 is fixed on the base support beam 120.

[0046] Reference Figure 3 and Figure 4 The main load-bearing structure 200 includes multiple I-shaped top beams 210. Each I-shaped top beam 210 is hingedly connected to a support steel column 220 at both ends in the longitudinal direction. Both support steel columns 220 can be folded inward to be parallel to the longitudinal direction of the I-shaped top beam 210. A placement slot 130 is defined on the top surface of each base support beam 120. The placement slot 130 extends along the longitudinal direction of the base support beam 120. The free end of the support steel column 220 can be inserted into the placement slot 130 and can slide along the longitudinal direction of the placement slot 130.

[0047] Reference Figure 3 、 Figure 4 and Figure 5 Each base joist 120 is provided with a plurality of positioning slots 140, which are spaced apart along the length of the placement slot 130. The positioning slots 140 are used to clamp and position the support steel columns 220 sliding in the placement slot 130. To ensure that the support steel columns 220 are not affected by the positioning slots 140 and can slide smoothly in the placement slot 130, the base joist 120 is provided with a plurality of supporting assemblies 150. The plurality of supporting assemblies 150 on the same base joist 120 are arranged in a one-to-one correspondence with the plurality of positioning slots 140.

[0048] Each group of supporting components 150 includes a screw 151 passed through the side of the base supporting beam 120, and the screw 151 is threadedly connected to the base supporting beam 120. A supporting plate 152 is slidably connected in each positioning groove 140. The supporting plate 152 is vertically arranged, and the top surface of the supporting plate 152 is flush with the bottom surface of the placement groove 130. One end of the screw 151 passed through the inside of the base supporting beam 120 is rotatably connected to the supporting plate 152. By rotating the screw 151, the top support plate 152 can be pushed to move, so that the top support plate 152 moves to a position close to the middle of the positioning groove 140. When the supporting steel column 220 slides in the placement groove 130, the top support plate 152 can smoothly pass over the positioning groove 140 and then enter the positioning groove 140 where it needs to be clamped. When the positioning groove 140 needs to position and clamp the supporting steel column 220, the screw 151 drives the top support plate 152 to move back to one side of the positioning groove 140, so that the supporting steel column 220 can fall into the positioning groove 140, thereby realizing the positioning of a group of supporting steel columns 220. Then, by rotating the screw 151 again, the top support plate 152 can be pushed to tighten the supporting steel column 220, and then the support steel column 220 can be fixed to the base beam 120 with bolts.

[0049] Reference Figure 6 and Figure 7 There are two connecting ports on the top of each I-shaped top beam 210. The two connecting ports are respectively located near the two ends of the I-shaped top beam 210 and are arranged one by one with the two supporting steel columns 220. A connecting pipe 230 is inserted into each connecting port. The connecting pipe 230 passes through the I-shaped top beam 210 and is inserted into its corresponding supporting steel column 220 to lock the supporting steel column 220, thereby fixing the supporting steel column 220 to the I-shaped top beam 210.

[0050] Reference Figure 6 and Figure 7 The two plugging rods 242 are parallel to the lifting rod 241, and the two supporting steel columns 220 to which each I-shaped top beam 210 is hinged are provided with a plugging hole 243. The two plugging holes 243 are arranged in a one-to-one correspondence with the two plugging rods 242. The plugging rods 242 can be inserted into their corresponding plugging holes 243 as the lifting rod 241 slides, thereby locking the two supporting steel columns 220.

[0051] At the same time, in order to improve the stability of the two supporting steel columns 220 after locking, a blocking plate 245 is fixedly connected to the top of the lifting rod 241, and a spring 244 is sleeved on the outer side of the lifting rod 241. One end of the spring 244 is fixedly connected to the blocking plate 245, and the other end of the spring 244 is fixedly connected to the I-shaped top beam 210. The spring 244 applies a downward pulling force to the lifting rod 241 to allow the two connecting rods 242 to be inserted into the connecting holes 243 opened in the two supporting steel columns 220.

[0052] Reference Figure 7 and Figure 8 The I-shaped top beam 210 includes a solid portion 211 located in the middle position and hollow portions 212 located on both sides of the solid portion 211. The lifting rod 241 and the two connecting rods 242 are slidably connected to the solid portion 211. A drainage hole 213 is provided on the solid portion 211. In this embodiment, two drainage holes 213 are provided. In other embodiments, three, four or more drainage holes 213 can be provided. Each drainage hole 213 is provided at the top of the I-shaped top beam 210. The ends of the two drainage holes 213 are respectively connected to the two hollow portions 212 of the I-shaped top beam 210. Each connecting pipe 230 is provided with a connecting hole 231. The hollow portion 212 is connected to the interior of the supporting steel column 220 adjacent to it through its corresponding connecting hole 231.

[0053] When the supporting steel column 220 is inserted into its corresponding positioning groove 140 , the insertion hole 243 formed on the supporting steel column 220 is flush with the bottom surface of the placement groove 130 .

[0054] After the building construction is completed and the floor panel structure 400 is laid on multiple I-shaped top beams 210, the factory building needs to be cleaned regularly. Since the overall structure is a steel frame, the floor panel 410 has poor drainage performance. By using the setting of the drainage hole 213, when water is accidentally spilled or cleaned on the building floor panel 410, the sealing plate 245 is pulled upward to open the drainage hole 213. Then the water can flow along the drainage hole 213 into the hollow part 212 of the I-shaped top beam 210, and then enter the supporting steel column 220, and then be discharged through the placement groove 130, thereby improving the drainage performance of the factory building.

[0055] Reference Figure 1 and Figure 2 In other embodiments, to enhance the mounting strength between two adjacent I-shaped top beams 210, a U-shaped plate can be secured between the two adjacent I-shaped top beams 210. The U-shaped plate has two sets of reinforcement holes. Reinforcement bolts pass through the reinforcement holes and the I-shaped top beams 210 and are then threaded into nuts. The U-shaped plate and bolts work together to secure the two adjacent I-shaped top beams 210, maintaining the connection strength between them.

[0056] Reference Figure 1The wall panel structure 300 includes several wall panels 310, which are prefabricated in the factory and located between two adjacent supporting steel columns 220 on one side. The supporting rods can be connected by bolts. The wall panels 310 are connected to the supporting steel columns 220 and the supporting rods by rivets, etc. to complete the assembly of the wall panel structure 300.

[0057] The floor panel structure 400 includes several floor panels 410, which are prefabricated in the factory. After the main load-bearing structure 200 is assembled, the floor panels 410 are laid on multiple I-shaped top beams 210. The floor panels 410 are fixed by fasteners such as bolts or rivets, and the floor panels 410 are made flush with the blocking panels 245.

[0058] Reference Figure 1 and Figure 2 The tops of the multiple connecting pipes 230 in the same row are fixedly connected with the second-layer base support beams 500. The second-layer base support beams 500 have the same structure as the base support beams 120 at the bottom. The construction workers can assemble the I-shaped steel beams of the next layer after assembling the second-layer base support beams 500. Similarly, the construction workers can build multi-layer structures according to the design requirements and lay waterproof roof panels on the I-shaped top beams 210 on the top layer.

[0059] The implementation principle of a modular low-rise assembled special-shaped column steel structure house system in the embodiment of the present application is as follows: first, according to the design requirements of the house, the basic structure 100, the I-shaped top beam 210, and the supporting steel columns 220 are prefabricated in the factory according to the design requirements, and the supporting steel columns 220 are assembled with the I-shaped top beam 210. After the supporting steel columns 220 are folded to a position close to the I-shaped top beam 210, the supporting steel columns 220 are locked by plugging the plug rods 242 into the plug holes 243 on the supporting steel columns 220, and then the house can be transported;

[0060] After transporting the various structural modules of the house system to the construction site, first fix the base support beam 120 to the ground, then hoist the I-shaped top beam 210, and release the lock of the supporting steel columns 220 on both sides of the I-shaped top beam 210, so that the supporting steel columns 220 are rotated until the I-shaped top beam 210 is vertical, and the connecting pipe 230 fixes the I-shaped top beam 210 and the supporting steel columns 220, then place the supporting steel columns 220 into the placement groove 130 of the base support beam 120, and then push the I-shaped top beam 210 to move so that the supporting steel columns 220 are inserted into their corresponding positioning grooves 140, and then use the top support plate 152 to tighten and use bolts to reinforce, so as to realize the assembly of the main load-bearing structure 200 of the house, and then assemble the wall panels 310 and floor panels 410. At the same time, the overall structural module can be strengthened by bolt connection.

[0061] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
