Description

Technical Field

[0001] The present invention relates to the technical field of steel structure buildings, and particularly relates to a prefabricated steel structure building. Background Art

[0002] A prefabricated steel structure building is a new type of building technology, which is characterized by using prefabricated components and assemblies to complete the assembly of the building through on-site assembly. This building technology has the advantages of being fast, efficient, and environmentally friendly, and is increasingly favored by people. The prefabricated steel structure building also has the advantage of being reusable, because steel can be recycled and reused, and it can also be disassembled and recycled when the building is abandoned, reducing waste.

[0003] Existing prefabricated steel structure buildings have many advantages. They are fast and efficient during installation, and the steel can be recycled and reused. Therefore, prefabricated steel structure buildings are more environmentally friendly than traditional buildings, and have advantages such as high durability and antioxidant ability. The existing patent (Publication No.: CN 216075494 U) discloses a prefabricated steel structure building system, which relates to a building system, and particularly to a prefabricated building system. It includes a prefabricated steel structure skeleton system, a prefabricated steel structure floor system, a prefabricated steel structure exterior wall system, and a prefabricated steel structure interior wall system. However, this assembly structure has the following disadvantages: During installation, connection structures such as welding nails and bolts are still required, and the construction is relatively complex, requiring professional personnel and professional equipment for operation. At the same time, on-site assembly is required, so the requirements for the construction site are relatively high; This prefabricated steel structure building has a large number of components, and there are relatively complex connection structures at the steel beams, steel columns, and connection plates, etc. Therefore, the design and processing of each structure and each component are relatively complex, and these steel materials are pre-designed and pulled to the site for installation. It is very easy to have problems during installation due to inaccurate design or processing. If reprocessing and design are required because it cannot be installed, it will cost again and is relatively wasteful of resources; Although the steel structure has high durability and antioxidant ability, damage may still occur during long-term use, especially at the connection parts. Therefore, regular inspections and repairs are required. However, the disassembly, decoration, and repair of existing prefabricated steel structure buildings are all relatively troublesome and waste energy. Summary of the Invention

[0004] The main purpose of the present invention is to provide a prefabricated steel structure building, which can effectively solve the problems in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0006] A prefabricated steel structure building, characterized in that: it includes columns, a base is installed at the lower end of the columns, tenon shoulders are installed on the upper and lower parts of the columns respectively, sliding grooves are arranged around the columns on four sides, an extension bin is arranged at the top of the columns, a steel bar groove is arranged inside the columns, the columns are connected to cross beams at the tenon shoulders, tenon tongues are arranged at both ends of the cross beams, fixing holes are arranged through the tenon tongues, a locking mechanism is arranged in the middle part of the cross beams, sliding grooves are arranged around the cross beams, a movable wall is installed between the cross beams, protruding sliding platforms are arranged in three directions of the movable wall, and fixing anchor holes are arranged at the upper, middle and lower parts of the movable wall.

[0007] Preferably, the tenon tongues arranged at both ends of the cross beam have different structures.

[0008] Preferably, the tenon shoulders arranged on the columns are connected to the tenon tongues at both ends of the cross beam through a mortise and tenon structure.

[0009] Preferably, the locking mechanism arranged in the middle of the cross beam is designed with a movable spring and can be pressed down when needed.

[0010] Preferably, the steel bar groove arranged inside the column corresponds to the fixing hole after the tenon tongue is installed on the tenon shoulder.

[0011] Preferably, protruding sliding platforms are arranged in three directions of the movable wall, and a concave sliding groove is arranged in the other direction.

[0012] Preferably, after the columns and cross beams are connected through the tenon shoulders and tenon tongues, fixing steel bars can be inserted into the steel bar grooves, and the fixing steel bars will pass through the fixing holes arranged on the tenon tongues for reinforcement.

[0013] Preferably, the tenon shoulder is a detachable movable part and can be installed in the extension bin of the column.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The prefabricated steel structure building adopted in the present invention as a whole draws on the traditional Chinese mortise and tenon structure and traditional building methods. First, the overall load-bearing columns and beams are fixed as the load-bearing framework, and the overall framework connection method adopts the mortise and tenon structure. During the installation process, the connection can be ensured to be safe and reliable without the need to rely on screws or welding. After the framework is installed, only modular movable walls need to be installed at the wall to complete the construction; the load-bearing columns and beams are respectively designed in a unified structural style, which is more unified in overall processing, reduces waste of resources, and is easier to install; modular design is adopted, and each structure is a separate component, and only the corresponding materials need to be purchased according to the site and needs, which is more convenient. Moreover, for steel structure buildings, regular inspection and maintenance are required, and the installation and disassembly of modular components are more convenient.

[0028] Embodiment

[0029] Please refer to Figure 1-8 , the present invention provides a technical solution:

[0030] An assembled steel structure building, characterized in that: it includes a column 1, a base 101 is installed at the lower end of the column 1, tenon shoulders 102 are installed on the upper half and the lower half of the column 1 respectively, sliding grooves 103 are provided around the four sides of the column 1, an extension bin 104 is provided at the top of the column 1, a steel bar groove 105 is provided inside the column 1, the column 1 is connected to a cross beam 2 at the tenon shoulder 102, tenon tongues 201 are provided at both ends of the cross beam 2, through holes 203 are provided on the tenon tongues 201, a snap lock 202 is provided in the middle part of the cross beam 2, sliding grooves 103 are provided around the cross beam 2, a movable wall 3 is installed between the cross beams 2, protruding sliding platforms 301 are provided in three directions of the movable wall 3, and fixed anchor holes 302 are provided at the upper, middle and lower parts of the movable wall 3.

[0031] The tenon tongues 201 provided at both ends of the cross beam 2 have different structures.

[0032] The tenon shoulders 102 provided on the column 1 are connected to the tenon tongues 201 at both ends of the cross beam 2 through a tenon and mortise structure.

[0033] The latch 202 provided in the middle of the crossbeam 2 is designed with a movable spring, and the latch 202 can be pressed down when needed.

[0034] The steel bar groove 105 provided inside the column 1 corresponds to the fixing hole 203 after the tongue 201 is installed on the tenon shoulder 102.

[0035] The movable wall 3 is provided with protruding sliding platforms 301 in three directions, and a recessed sliding groove 103 is provided in the other direction.

[0036] After the column 1 and the crossbeam 2 are connected through the tenon shoulder 102 and the tongue 201, a fixing steel bar 4 can be inserted into the steel bar groove 105, and the fixing steel bar 4 will pass through the fixing hole 203 provided on the tongue 201 for reinforcement.

[0037] The tenon shoulder 102 is a detachable movable component and can be installed in the extension bin 104 of the column 1.

[0038] In this embodiment, when installing the overall prefabricated steel structure building, it is first necessary to determine the installation area, and then determine the installation location of the columns in the determined installation area. The base of the column is buried 60 to 80 centimeters deep underground, and the depth of burial is determined according to the bearing capacity of the land. The deeper it is buried, the more firm it is. Then, generally, one column is installed every 3 to 4 meters in the installation area to ensure the bearing capacity of the column. After the columns are installed, the crossbeams are installed. Generally, two circles of crossbeams are installed at the load-bearing positions on the ground plane and the roof. The crossbeams are fixed in a circle by inserting the tongues into the tenon shoulders. After fixing a circle of crossbeams, the connection part of the tenon shoulders is inserted into the extension bin of the column to ensure that the crossbeams can be fixed on the columns. After the crossbeams and columns are both installed, steel bars are inserted into the steel bar grooves of the columns. The steel bars can pass through the fixing holes provided on the tongues to fix the connection structure of the entire building frame. At the same time, concrete can be poured into the steel bar grooves after inserting the steel bars to reinforce the gaps at the joints.

[0039] In this embodiment, after installing the columns and crossbeams of the building frame, sliding grooves are provided in the middle of the columns and crossbeams. These sliding grooves are used to fix the movable wall. The movable wall is provided with convex platforms in three directions, and the convex platforms on the movable wall correspond to the sliding grooves. When installing the movable wall, the latch on the crossbeam is pressed in, and the movable wall can be installed into the sliding groove through the notch of the latch. The width of a single installed movable wall is about 30 centimeters. When installing the movable wall into the sliding groove, the fixed anchor holes on the adjacent walls can be connected by using steel plates or screws to fix the entire wall surface.

[0040] In this embodiment, the individual columns, beams, and movable wall structures are all the same and can be uniformly processed according to a single template during processing. At the same time, since the building structure is modularly designed, the corresponding length and width can be designed according to actual needs. After the frame and walls are installed, gypsum boards and wooden boards can be installed on both sides of the wall according to the fixed anchor holes on the movable wall to achieve better heat insulation, heat preservation, and other effects. The columns and beams play a role of a load-bearing frame in the entire prefabricated building to maintain the stability of the walls and the entire structure, and the movable wall can fix wallboards of different materials on the fixed pores according to needs to achieve a better living experience.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only to illustrate the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and all these changes and improvements fall within the scope of the present invention claimed.
