Description

Technical Field

[0001] This utility model relates to the field of steel structure building technology, specifically a prefabricated building structure. Background Technology

[0002] In today's construction industry, steel structure buildings, with their significant advantages such as high strength, light weight, and short construction period, are widely used in various industrial plants, commercial buildings, public facilities, and high-rise residential projects. Traditional steel structure construction mainly employs a combination of on-site welding and bolting. While welding plays a crucial role in the integrity and stability of the structure, as the primary means of connecting key components such as vertical and horizontal beams, it has revealed many problems that urgently need to be addressed during actual construction.

[0003] Welding operations generate a large amount of welding fumes, which are complex in composition and contain various harmful substances such as metal oxides, fluorides, and nitrogen oxides. For example, in manual arc welding, approximately 5-8 grams of welding fumes are produced per kilogram of welding rod; the amount of welding fumes generated in gas shielded welding is also considerable. Long-term exposure to high concentrations of welding fumes can seriously harm the health of construction workers, causing occupational diseases such as pneumoconiosis, respiratory diseases, and metal fume fever, severely impacting their work capacity and quality of life.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 A prefabricated building structure includes multiple sets of support units 20, multiple outer wall panels 30, and a roof panel 40. The bottom ends of the multiple sets of support units 20 are fixed to the ground foundation 10, the multiple outer wall panels 30 are installed and fixed to the outside of the multiple sets of support units 20, the multiple roof panels 40 are installed and fixed to the top of the multiple sets of support units 20, and a door panel is installed on at least one side of the building via hinges, thus forming a complete steel structure building.

[0025] See Figure 2 The support unit 20 includes several vertical beam assemblies and several horizontal support beams 24. The vertical beam assemblies in the support unit 20 are spaced apart in the same row or column, and the tops of every two adjacent support units 20 are connected and fixed to both ends of a horizontal support beam 24 using fasteners. Furthermore, the vertical beam assembly in this embodiment is composed of a positioning seat 21, several vertical support beams 22, and several connecting parts 23. The bottom of the positioning seat 21 is embedded in the ground foundation 10 and is used to position the vertical beam assembly. The several vertical support beams 22 are stacked vertically, and the lowest vertical support beam 22 is connected and fixed to the positioning seat 21 using fasteners. A connecting part 23 is fitted at the joint of every two adjacent vertical support beams 22, and the connecting part 23 is connected and fixed to the two adjacent vertical support beams 22 using fasteners, so that the several vertical support beams 22 together form a vertical support of the required height.

[0026] See Figure 3The positioning seat 21 includes a ground embedding part 211 and at least two threaded rods 212. The ground embedding part 211 is embedded in the ground foundation 10, and at least two threaded rods 212 are fixedly connected to the top of the ground embedding part 211. The top ends of the threaded rods 212 extend above the ground foundation 10. The threaded rods 212 are used to cooperate with the positioning and fixing of the vertical support beam 22.

[0027] See Figure 3 The vertical support beam 22 includes a rectangular steel beam 221 and two connecting pieces 222. The rectangular steel beam 221 has a hollow inner cavity and multiple openings formed on the outer walls at both ends, allowing it to be connected to the connecting part 23 using fasteners. The two connecting pieces 222 are respectively formed at both ends of the rectangular steel beam 221, and each rectangular steel beam 221 has four grooves 223 distributed on different surfaces on its outer wall. The grooves 223 are used for positioning when the connecting part 23 is connected. In addition, the rectangular steel beam 221 near the positioning seat 21 has a through hole formed on its bottom connecting piece 222 through which a threaded rod 212 passes, allowing the rectangular steel beam 221 near the positioning seat 21 to be positioned above the positioning seat 21. Then, a nut threadedly connected to the threaded rod 212 is fitted onto it and tightened, which limits and fixes the vertical support beam 22 near the positioning seat 21.

[0028] See Figure 3 The connecting part 23 includes four I-shaped plates 231 and two L-shaped plates 232. The four I-shaped plates 231 are positioned and inserted into the outer sides of two adjacent vertical support beams 22 using grooves 223 on the adjacent sides of the connecting piece 222. The two L-shaped plates 232 are symmetrically arranged on the outer sides of the four L-shaped plates 232. When connecting two adjacent vertical support beams 22, fasteners can be inserted through the L-shaped plates 232, the adjacent I-shaped plates 231, and connected to the rectangular steel beam 221.

[0029] See Figure 4 The transverse support beam 24 includes a horizontal steel beam 241 whose length is adapted to the spacing between two adjacent sets of vertical beam assemblies. At both ends of the horizontal steel beam 241, a fitting step portion 242 is formed. The fitting step portion 242, when engaged with an adjacent groove 223, allows the transverse support beam 24 to be positioned between two adjacent vertical support beams 22. The fitting step portion 242 is connected to the adjacent rectangular steel beam 221 by fasteners, thus fixing the transverse support beam 24 to the adjacent vertical support beam 22. A reinforcing rib 243, with a length adapted to the length of the horizontal steel beam 241, is also formed at the bottom of the horizontal steel beam 241. The reinforcing rib 243 is used to reduce deformation of the horizontal steel beam 241 under load.

[0030] See Figure 5 and Figure 6The outer wall panel 30 has a covering bend 31 at one end near the connecting piece 222, and the covering bend 31 covers the connecting piece 222 inside it, so that the support unit 20 can be covered inside after the outer wall panel 30 and the rectangular steel beam 221 are connected and fixed by fasteners. The two ends of the top plate 40 are bent downwards, and the bent parts at both ends of the top plate 40 are inserted into the covering bend 31 formed at the top of the adjacent outer wall panel 30. The top plate 40 and the adjacent outer wall panel 30 are connected and fixed by fasteners.
