Description

Technical Field

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

[0002] Prefabricated steel structure buildings offer flexible spatial layouts, enabling industrialized and standardized housing construction with short construction periods and no on-site casting nodes. Installation is faster than prefabricated concrete structures. Furthermore, steel is a ductile material, making it lighter and more earthquake-resistant than brick-concrete or concrete structures. While steel walls are typically assembled through welding by workers, current prefabricated steel structure wall assembly technology suffers from lower strength, longer construction times, difficulty in ensuring horizontal or vertical alignment of walls, and poor assembly precision.

[0003] Utility model CN217299355U discloses a prefabricated steel structure wall component, comprising two sets of walls and a channel-shaped component disposed on the top of the outer surface of the walls. The front of each wall has a rectangular notch. Multiple sets of hinge plates are fixedly connected to the inner side of the channel-shaped component. The hinge plates on the left and right sides are rotatably connected via hinge shafts. Four sets of sliding rods are slidably inserted into the front and back of the channel-shaped component. This prefabricated steel structure wall component, through the cooperation of the channel-shaped component, hinge shafts, T-shaped plates, positioning holes, and positioning bolts, allows the channel-shaped component to fix the wall. The positioning holes and positioning bolts fix the two sets of channel-shaped components. There are two assembly modes between the two sets of walls: parallel assembly and perpendicular assembly, which further facilitates the parallel and perpendicular assembly work of the two sets of walls and improves the assembly accuracy between the two sets of walls.

[0004] However, the above-mentioned existing technology still has the following shortcomings when used: 1. When splicing, the channel-shaped component is in an overall exposed state, which can easily cause interference during the later construction of the wall; 2. The channel-shaped component is an integral movable connection structure, that is, it does not have a disassembly function. During installation, it is necessary to first ensure that the two walls are in a precise docking position before the channel-shaped component can be installed. This setting increases the labor intensity of the wall assembly operation.

[0005] Therefore, this utility model provides a prefabricated steel structure wall component. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a prefabricated steel structure wall component to solve the problems mentioned in the background technology. The connection mechanism of this utility model for connecting wall one and wall two has the function of being hidden after installation, eliminating the potential interference of later construction operations, and has the advantages of labor-saving fastening connection of wall one and wall two.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a prefabricated steel structure wall component, including wall one and wall two, the upper and lower ends of wall one and wall two are fixedly connected by a connecting mechanism, rectangular notches are provided at the corners of wall one and wall two near the connecting mechanism, and grooves are provided on the upper and lower sides of wall one and wall two. The connecting mechanism includes a positioning plate and a positioning disc, one end of the positioning plate is located in the groove and the two are connected by bolts, a coaxial limiting post is fixedly connected to the surface of the positioning disc, and a number of limiting pins evenly distributed around the limiting post are also fixedly connected to the surface of the positioning disc, and a locking hole is provided on the positioning plate to engage with the limiting pin, and one end of the positioning plate engages with the limiting post.

[0008] Furthermore, at least two threaded holes are provided at the bottom of the groove, and a positioning hole opposite to the threaded holes is provided on one side of the positioning plate.

[0009] Furthermore, two positioning pins are welded to one side of the positioning plate, and a slot is provided at the bottom of the groove to engage with the positioning pins.

[0010] Furthermore, the limiting pile is a round bar structure, and the other end of the positioning plate has an inner arc surface that abuts against the outer peripheral wall of the limiting pile. The width of the positioning plate is smaller than the outer diameter of the limiting pile.

[0011] Furthermore, the diameter of the circle corresponding to the arc on the inner arc surface is equal to the outer diameter of the limiting pile.

[0012] Furthermore, a locking nut is screwed onto the limiting stake.

[0013] Furthermore, one end of the groove is connected to the rectangular notch.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. In this utility model, grooves are opened on the upper and lower sides of both wall one and wall two. The connecting mechanism includes a positioning plate that is connected to the groove by bolts. Rectangular notches are opened at the corners of wall one and wall two. The positioning plate on the connecting mechanism is located in the rectangular notch. This arrangement makes the entire connecting mechanism hidden after installation, which has the advantage of eliminating the risk of interference in later construction compared with the prior art.

[0016] In this invention, the positioning plate and positioning disc are detachable structures. When in use, the positioning plate is first installed in the grooves on wall one and wall two, and then the positioning plates on wall one and wall two are fixedly connected by plugging them into the positioning disc. Compared with the prior art, this structure greatly reduces the labor intensity of assembly operations. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1 to 3 This utility model provides a technical solution: a prefabricated steel structure wall component, including wall 1 and wall 2. The upper and lower ends of wall 1 and wall 2 are fixedly connected by a connecting mechanism 3. Rectangular notches 5 are provided on the corners of wall 1 and wall 2 near the connecting mechanism 3. The rectangular notches 5 make way for part of the structure on the connecting mechanism 3.

[0023] Furthermore, grooves 4 are provided on the upper and lower sides of wall 1 and wall 2. The connecting mechanism 3 includes a positioning plate 31 and a positioning disc 32. The positioning plate 31 and positioning disc 32 are detachable structures. One end of the positioning plate 31 is located in the groove 4 and the two are connected by bolts. In a preferred embodiment, at least two threaded holes 41 are provided at the bottom of the groove 4, and a positioning hole 311 opposite to the threaded hole 41 is provided on one side of the positioning plate 31. In use, the positioning hole 311 on the positioning plate 31 is connected to the threaded hole 41 by bolts. In use, one positioning plate 31 is connected to each of wall 1 and wall 2. That is, before fastening the connection between wall 1 and wall 2, the positioning plate 31 can be installed on wall 1 and wall 2 first, and then two adjacent positioning plates 31 on wall 1 and wall 2 can be fixedly connected by the positioning disc 32. The rectangular notch 5 is used to make way for the positioning disc 32.

[0024] Specifically, a coaxial limiting post 321 is fixedly connected to the surface of the positioning plate 32. Several limiting pins 322, evenly distributed around the limiting post 321, are also fixedly connected to the surface of the positioning plate 32. The number of limiting pins 322 is determined according to the included angle after the connection of wall 1 and wall 2. For example, when wall 1 and wall 2 need to be connected vertically and coplanarly, the number of limiting pins 322 is four. The positioning plate 31 has a locking hole 314 that engages with the limiting pin 322, and one end of the locking hole 314 engages with the limiting post 321. When the locking hole 314 and the limiting pin 322 are engaged, the positioning plate 31 and the positioning plate 32 are in a connected and rotatable state. Moreover, the engagement between the positioning plate 31 and the limiting post 321 directly locks the connection between the positioning plate 31 and the positioning plate 32.

[0025] In summary, the method of first connecting a positioning plate 31 to wall 1 and wall 2 respectively, and then fixing the two positioning plates 31 together with a positioning disc 32 can greatly reduce the labor intensity of assembly and connection.

[0026] Furthermore, the limiting pile 321 is a round bar structure, and the other end of the positioning plate 31 is provided with an inner arc surface 313 that abuts against the outer peripheral wall of the limiting pile 321. The limiting pile 321 uses the inner arc surface 313 to limit the positioning plate 31. The width of the positioning plate 31 is smaller than the outer diameter of the limiting pile 321. The positioning plate 32 and the two positioning plates 31 are kept parallel. Then, the positioning plate 32 is controlled to move closer to the positioning plate 31, so that the limiting pile 321 is aligned with the inner arc surface 313 and the limiting pin 322 is aligned with the locking hole 314. Then, they are directly inserted. After insertion, the positioning plates 31 on wall 1 and wall 2 are fixedly connected through the positioning plate 32. This setting makes the docking operation of the positioning plate 32 and the positioning plate 31 more convenient.

[0027] The diameter of the circle corresponding to the arc on the inner arc surface 313 is equal to the outer diameter of the limiting post 321. This arrangement ensures that there will be no shaking when the inner arc surface 313 of the positioning plate 31 and the limiting post 321 are in contact, making the connection more secure.

[0028] In this embodiment, a locking nut 3211 is screwed onto the limiting post 321, that is, the limiting post 321 has threads. When the locking nut 3211 is tightened, it can effectively prevent the positioning disc 32 and the positioning plate 31 from separating, and at the same time, it can clamp the positioning disc 32 and the positioning plate 31.

[0029] In this embodiment, two positioning pins 312 are welded to one side of the positioning plate 31, and a slot 42 is provided at the bottom of the groove 4 to engage with the positioning pins 312. This arrangement can improve the connection strength between the positioning plate 31 and the groove 4.

[0030] Working principle: When it is necessary to connect wall 1 and wall 2 coplanarly, firstly, connect a positioning plate 31 to the groove 4 on wall 1 and wall 2 respectively by bolts. Then, put the opposite surfaces of the two walls 1 and wall 2 together. Taking the connecting mechanism 3 at the top of wall 1 and wall 2 as an example, the positioning plate 32 moves from top to bottom, so that the limiting post 321 on it is inserted between the inner arc surface 313 on the two positioning plates 31. At the same time, the limiting pin 322 and the locking hole 314 are aligned. When the positioning plate 32 and the two positioning plates 31 are put together, the locking nut 3211 is installed on the limiting post 321. At this time, wall 1 and wall 2 are tightly connected.

[0031] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
