[0002] In the field of construction engineering, although traditional cast-in-place concrete buildings dominate, they are increasingly restricted due to their long construction period and serious environmental pollution. With the popularization of green building concepts and technological advances, prefabricated buildings have gradually become a new trend in the construction industry with their advantages of fast construction speed, strong quality controllability, environmental protection and energy saving. Especially in the low-rise building market, prefabricated steel structures are highly favored due to their excellent seismic performance, high strength and light weight.

[0003] Traditional steel structure house structures 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 overall steel structure. However, due to the large number of special-shaped steel columns required for the house, it still takes a lot of assembly time at the construction site, and 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

When the supporting steel column needs to be temporarily supported, the screw rod 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 rod 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 rod is rotated again to push the top support plate to press the supporting steel column tightly.

DETAILED DESCRIPTION

[0026] The following is combined with Figure 1-9 This application is described in further detail.

[0027] The embodiment of the present application discloses a modular low-rise assembled special-shaped column steel structure house system.

[0028] Reference Figure 1 and Figure 2A modular low-rise assembled special-shaped column steel structure house system 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, serving as the foundation of the overall steel structure house and responsible for connecting and fixing with the ground; the main load-bearing structure 200 is composed of special-shaped steel columns, serving as the main force support of the house, supporting the main load of the entire house, the wall structure is used as the wall panel of the house, and the floor panel structure 400 is used as the floor support of the house. The assembly and construction of the entire house system is realized by assembling multiple modules separately.

[0029] Reference Figure 2 and Figure 3 The basic 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 all 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. The main load-bearing structure 200 is fixed on the base support beam 120.

[0030] Reference Figure 3 and Figure 4 The main load-bearing structure 200 includes a plurality of I-shaped top beams 210, each of which is hinged with a support steel column 220 at both ends in the length direction. Both support steel columns 220 can be folded inward to be parallel to the length direction of the I-shaped top beam 210. A placement groove 130 is provided on the top surface of each base support beam 120, and the placement groove 130 is provided along the length direction of the base support beam 120. The free end of the support steel column 220 can be inserted into the placement groove 130 and can slide along the length direction of the placement groove 130.

[0031] Reference Figure 3 , Figure 4 and Figure 5 Each base support beam 120 is provided with a plurality of positioning grooves 140, which are arranged at intervals along the length direction of the placement groove 130, and the positioning grooves 140 are used to clamp and position the support steel column 220 sliding in the placement groove 130. In order to ensure that the support steel column 220 is not affected by the positioning groove 140 and can slide smoothly in the placement groove 130, a plurality of top support assemblies 150 are arranged on the base support beam 120, and the plurality of top support assemblies 150 located on the same base support beam 120 are arranged one by one corresponding to the plurality of positioning grooves 140.

[0032] Each group of supporting assemblies 150 includes a screw rod 151 passing through the side of the base supporting beam 120, the screw rod 151 is threadedly connected to the base supporting beam 120, and 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 rod 151 passing 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 above 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 supporting steel column 220 can be fixed to the base beam 120 with bolts.

[0033] Reference Figure 6 and Figure 7 Two connection ports are provided on the top of each I-shaped top beam 210. The two connection 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 connection port. The connecting pipe 230 passes through the I-shaped top beam 210 and is inserted into the corresponding supporting steel column 220 to lock the supporting steel column 220, thereby fixing the supporting steel column 220 and the I-shaped top beam 210.

[0034] Reference Figure 6 and Figure 7 In order to ensure the stability of the I-shaped top beam 210 and the supporting steel column 220 during folding and transportation, a locking assembly 240 is provided on each I-shaped top beam 210, and the locking assembly 240 is located near the middle of the I-shaped top beam 210. The locking assembly 240 includes a lifting rod 241 that passes through the middle of the I-shaped top beam 210, and the lifting rod 241 is slidably connected to the I-shaped top beam 210. Two plug-in rods 242 are fixedly connected to the bottom end of the lifting rod 241, and the two plug-in rods 242 are parallel to the lifting rod 241. Plug-in holes 243 are opened on the two supporting steel columns 220 hinged to each I-shaped top beam 210, and the two plug-in holes 243 are arranged one by one with the two plug-in rods 242. The plug-in rod 242 can be inserted into its corresponding plug-in hole 243 as the lifting rod 241 slides, thereby locking the two supporting steel columns 220.

[0035] 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 plug-in rods 242 to be inserted into the plug-in holes 243 opened in the two supporting steel columns 220.

[0036] 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 plug-in 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.

[0037] When the supporting steel column 220 is inserted into the corresponding positioning groove 140 , the inserting hole 243 formed on the supporting steel column 220 is flush with the bottom surface of the placement groove 130 .

[0038] 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 the building floor panel 410 is accidentally spilled or cleaned, the sealing plate 245 is pulled upward to open the drainage hole 213, and 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.

[0039] Reference Figure 1 and Figure 2 In other embodiments, in order to improve the installation strength between two adjacent I-shaped top beams 210, a U-shaped plate can be clamped between the two adjacent I-shaped top beams 210. The U-shaped plate has two sets of reinforcement holes. The reinforcement bolts pass through the reinforcement holes and the I-shaped top beams 210 and are threadedly connected with nuts. By using the cooperation of the U-shaped plate and the bolts, the two adjacent I-shaped top beams 210 can be fixed and the connection strength between the two adjacent I-shaped top beams 210 can be maintained.

[0040] Reference Figure 1The wall panel structure 300 includes a plurality of wall panels 310, which are prefabricated in a factory and are located between two adjacent support steel columns 220 on one side and can be connected to support rods by bolts. The wall panels 310 are connected to the support steel columns 220 and the support rods by rivets, etc., to complete the assembly of the wall panel structure 300.

[0041] The floor panel structure 400 includes a plurality of floor panels 410, which are prefabricated in a factory. After the main load-bearing structure 200 is assembled, the floor panels 410 are laid on a plurality of 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 plates 245.

[0042] Reference Figure 1 and Figure 2 The tops of the multiple connecting pipes 230 located in the same row are fixedly connected with the second-layer base support beam 500. The second-layer base support beam 500 has the same structure as the base support beam 120 located at the bottom. The construction personnel only need to assemble the I-shaped steel beams of the next layer of the second-layer base support beam 500 assembly. By analogy, the construction personnel can build a multi-layer structure according to the design requirements and lay the waterproof roof panel on the top-layer I-shaped top beam 210.

[0043] 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: according to the design requirements of the house, firstly, the basic structure 100, the I-shaped top beam 210 and the supporting steel column 220 are prefabricated in the factory according to the design requirements, and the supporting steel column 220 is assembled with the I-shaped top beam 210, and after the supporting steel column 220 is folded to a position close to the I-shaped top beam 210, the supporting steel column 220 is locked by plugging the plug rod 242 with the plug hole 243 on the supporting steel column 220, and then the transportation can be carried out; 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, and then put 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 the 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 the floor panels 410. At the same time, the overall structural module can be strengthened by bolt connection.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
