Description

Technical Field

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

[0002] Steel structure beams are load-bearing components in building structures, mainly made of steel. They are characterized by high strength, light weight, and convenient construction, and are widely used in industrial plants, high-rise buildings, and other projects. Among them, steel structure beam splicing and installation refers to the process of connecting and fixing prefabricated steel beams on the construction site according to the design drawings. Common splicing methods include welding and bolting, and it is necessary to ensure that the strength of the joints meets the structural requirements.

[0003] However, when existing steel structure beams are spliced ​​with vertical steel columns, the beams are only fixed to the vertical steel columns by bolting or welding at the ends. This still results in insufficient structural stability and weak bending resistance. Although welding provides high connection strength, it is complex to construct, has high environmental requirements, and is not suitable for rapid on-site assembly. Traditional bolted connections, if relying solely on end butt joint plates and lacking lateral or upper and lower auxiliary structures, are prone to loosening or bending under stress, affecting the overall load-bearing capacity and long-term safety of the steel structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a steel structure beam splicing device, comprising I-shaped steel columns and steel beams;

A first bolt is passed through the U-shaped buckle, and one end of the first bolt passes through the outer wall of the connecting plate and the I-shaped steel column respectively. The top and bottom of the connecting plate are provided with bent portions.

[0008] Preferably, each of the two U-shaped buckle plates has a protrusion on an adjacent side, and a third bolt passes through the two protrusions.

[0009] Preferably, both the first bolt and the second bolt have nuts threaded onto their ends.

[0019] 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.

[0020] Please see Figure 1 An embodiment of this utility model provides a steel structure beam splicing device, including: an I-shaped steel column 1 and a steel beam 2.

[0021] Among them, such as Figure 1 and Figure 2 As shown, a connecting plate 3 is fixedly connected to the end of the steel beam 2. The outer wall of the I-shaped steel column 1 has several threaded holes 10 arranged at equal intervals along the vertical direction. Several second bolts 11 penetrate the outer wall of the connecting plate 3 along the vertical direction. The second bolts 11 are threaded into the inside of the threaded holes 10. By connecting the connecting plate 3 at the end of the steel beam 2 to the threaded holes 10 on the outer wall of the I-shaped steel column 1, the steel beam 2 and the steel column are firmly spliced. The connecting plate 3 is threaded into the threaded holes 10 by the second bolts 11 to ensure vertical fixation.

[0022] Furthermore, the top and bottom of the steel beam 2 are provided with reinforcing ribs 9. One side of the reinforcing rib 9 is welded to the outer wall of the connecting plate 3. The reinforcing rib 9 can improve the overall rigidity and load-bearing capacity of the steel beam 2 and achieve structural integration by welding it to the connecting plate 3.

[0023] In this embodiment, as Figures 1-4 As shown, the outer walls of the connecting plate 3 and the I-shaped steel column 1 are symmetrically provided with two U-shaped buckle plates 4. A first bolt 5 passes through the U-shaped buckle plate 4, and one end of the first bolt 5 passes through the outer walls of the connecting plate 3 and the I-shaped steel column 1 respectively. The top and bottom of the connecting plate 3 are provided with bending parts 7, and the U-shaped buckle plate 4 is a steel plate.

[0024] In use, U-shaped buckle plates 4 are symmetrically arranged on both sides of the connecting plate 3 and the I-shaped steel column 1. The first bolt 5 on the U-shaped buckle plate 4 passes through the outer wall of the connecting plate 3 and the I-shaped steel column 1 in sequence, thereby fixing the U-shaped buckle plate 4 and further enhancing the structural stability after the steel beam 2 and the I-shaped steel column 1 are spliced. In addition, the bending parts 7 at the top and bottom of the connecting plate 3 can prevent the U-shaped buckle plate 4 from sliding up and down and causing it to detach from the connecting plate 3 and the I-shaped steel column 1.

[0025] Furthermore, each of the two U-shaped buckle plates 4 has a protrusion 8 on an adjacent side, and a third bolt 12 passes through the two protrusions 8. Through the connection between the protrusions 8 and the third bolt 12, the two U-shaped buckle plates 4 can form a clamping and fixing structure when clamped, thereby enhancing their fixing strength and preventing loosening.

[0026] like Figure 1 and Figure 2 As shown, the ends of the first bolt 5 and the second bolt 11 are both threaded with nuts 6. Nuts 6 are used to provide axial tightening force to ensure that the connected parts are subjected to uniform force and facilitate disassembly and maintenance.

[0027] Specifically, refer to Figure 4 The inner wall of the U-shaped buckle plate 4 is fitted with a damping pad 13, which provides cushioning and anti-slip functions. During the process of the connecting plate 3 fitting the I-shaped steel column 1, it absorbs part of the impact force, reduces structural wear, and improves assembly stability.

[0028] Based on the above technical solution, the working steps of this solution are summarized as follows: In this embodiment, by connecting the connecting plate 3 at the end of the steel beam 2 to the threaded hole 10 on the outer wall of the I-shaped steel column 1, the steel beam 2 and the steel column are firmly spliced ​​together. The connecting plate 3 is threaded into the threaded hole 10 by the second bolt 11 to ensure vertical fixation.

[0029] Among them, U-shaped buckle plates 4 are symmetrically arranged on both sides of the connecting plate 3 and the I-shaped steel column 1. The first bolt 5 on the U-shaped buckle plate 4 passes through the outer wall of the connecting plate 3 and the I-shaped steel column 1 in sequence, thereby fixing the U-shaped buckle plate 4, further enhancing the structural stability of the steel beam 2 and the I-shaped steel column 1 after splicing, improving the overall bending resistance, and the device has a compact structure and is easy to install. In addition, the bending parts 7 at the top and bottom of the connecting plate 3 can prevent the U-shaped buckle plate 4 from sliding up and down and causing it to detach from the connecting plate 3 and the I-shaped steel column 1.

[0030] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
