Description

Technical Field

[0001] The present invention relates to steel structure technology, in particular to a stable steel structure. Background Art

[0002] Steel structures are structures made of steel and are one of the main types of building structures. They primarily consist of components such as beams, columns, and trusses, made from sections and plates. Rust removal and prevention processes include silanization, pure manganese phosphating, water washing and drying, and galvanizing. Components are typically connected using welds, bolts, or rivets. Due to its light weight and simple construction, it is widely used in large factories, stadiums, and high-rise buildings.

[0003] When installing existing steel structures, it is necessary to align the mounting holes on the two steel beams and then fix them with bolts. However, when the steel structure is lifted by a crane, it is easy to shake in the air. In addition, its steel beam structure is heavy and difficult to swing a small distance, making it difficult to align the mounting holes.

[0004] CN217557185U discloses a steel structure beam-column connection assembly structure. Although the steel beam body can be fixed on the wall by the assembly structure, during installation, the assembly structure is provided with a docking interface in the direction of the horizontal plane, and the distance between the two walls is certain, so it is difficult to ensure the smooth installation of the steel beam body during installation. Summary of the Invention

[0005] In order to solve the above-mentioned defects in the prior art, the present invention proposes a stable steel structure.

[0006] The technical solution of the present invention is achieved as follows:

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0031] like Figures 1 to 10 As shown, the stable steel structure of the present invention includes a vertical beam 1 and a transverse beam 2. The vertical beam 1 is an I-shaped steel beam, while the vertical beam 2 is a U-shaped steel beam. The vertical beam 1 is installed first, ensuring that the distance between the two vertical beams 1 is the same as the length of the transverse beam 2. Then, the transverse beam 2 can be installed through the positioning member 3 and the fixing member 4. The vertical beam 1 and the transverse beam 2 are connected by the positioning member 3 and the fixing member 4. The positioning member 3 is set on the vertical beam 1, and the fixing member 4 is set on the transverse beam 2.

[0032] A beam hole 5 is provided in the middle of the transverse beam 2, and the fixing part 4 is arranged in the beam hole 5. The mounting end 6 cooperates with the beam hole 5, and the area of ​​the mounting end 6 cooperates with the area of ​​the beam hole 5 to fix the mounting end 6 in the beam hole 5, and then install it on the transverse beam 2 through the first bolt 7.

[0033] A symmetrically arranged fixing portion 8 is provided on the transverse beam 2 . The cross section of the vertical beam 1 is in an I-shape. The transverse beam 2 is connected to the fixing portion 8 and the vertical beam 1 by a second bolt 9 .

[0034] By providing a fixing portion 8 on the transverse beam 2, the fixing portion 8 is arranged vertically on the transverse beam 2 to maintain its connection with the I-shaped vertical beam 1. Since the vertical beam 1 is an I-shaped steel beam with a steel structure in the middle and parallel steel structures at both ends, the fixing portion 8 can be connected to the vertical beam 1 via the second bolt 9.

[0035] When the positioning member 3 is installed and fixed, it is fixed on the positioning member 3 by the positioning column 10, and then connected to the vertical beam 1 by welding, so that the positioning member 3 can be stably set on the vertical beam 1.

[0036] Of course, in practice, the positioning member 3 can also be fixed to the vertical beam 1 by means of bolts, and welding operations are not required.

[0037] The positioning member 3 is in a U-shaped structure. The installation chamber 11 in the middle is also in a U-shaped structure, which can facilitate the insertion of the fixing member 4 into the fixing chamber for positioning.

[0038] The positioning member 3 defines a mounting chamber 11 in the center, with symmetrically positioned positioning arms 12 formed on either side of the mounting chamber 11. Positioning arms 12 are provided with guides 13 and locking portions 14 extending into the mounting chamber 11. The locking portions 14 are perpendicular to the guides 13, and symmetrically positioned positioning slots 15 are formed on either side of the locking portion 14. The positioning slots 15 are located at the lower end of the guides 13.

[0039] Multiple locating posts 10 are located on the vertical beam 1. Positioning holes are provided on the positioning member 3, which is connected to the vertical beam 1 via welding. Two of the locating posts 10 are located in the upper middle portion of the positioning arm 12, while the other two are located at the lower end. The locating posts 10 in the upper middle portion stabilize the positioning arm 12, preventing it from deforming due to the thrust of the fixing member 4.

[0040] The fixing member 4 consists of a mounting end 6 and a fixed end 16, which are connected by a connecting section 17. The upper end of the fixed end 16 is provided with symmetrically arranged extension arms 18, which are provided with deformable arms 19 that cooperate with the positioning groove 15. The deformable arms 19 are symmetrically arranged and have a locking groove 20 in the middle for the locking portion 14. The lower end of the fixed end 16 is provided with an arcuate portion 21 that cooperates with the mounting chamber 11.

[0041] The guide portion 13 is provided with an inclined guide surface 22 , which can guide the extension arm 18 and the deformation arm 19 on the fixing member 4 to deform toward the middle, thereby keeping them from passing the guide portion 13 and entering the locking groove 20 .

[0042] The lower ridgeline 23 of the guide surface 22, the matching surface 24 on the locking portion 14 and the vertical surface 25 in the installation chamber 11 are located on the same vertical plane, which facilitates the insertion of the fixing member 4 into the installation chamber 11.

[0043] A limiting hole 26 is provided in the middle of the arc-shaped portion 21, and a limiting protrusion 27 is provided in the installation chamber 11 to cooperate with the limiting hole 26. The limiting protrusion 27 can cooperate with the locking portion 14 to limit the position of the fixing member 4.

[0044] like Figure 5 As shown, the limiting protrusion 27 and the locking portion 14 can limit the movement of the fixing member 4 in the X direction, the positioning arm 12 can limit the movement of the fixing member 4 in the Y direction, and the guide portion 13 can limit the movement of the fixing member 4 in the Z direction. When the fixing member 4 is inserted into the installation chamber 11, the positioning member 3 can easily limit the position of the fixing member 4, thereby facilitating the installation of the transverse beam 2 between the two vertical beams 1. As a result, the mounting holes 28 on the fixing portion 8 can correspond to the mounting holes 28 on the vertical beams 1, and the second bolts 9 can connect the transverse beam 2 to the vertical beams 1.

[0045] A contraction region 29 is formed between the deformable arms 19 , and the deformable arms 19 are deformed toward the contraction region 29 due to the resistance of the guide portion 13 .

[0046] like Figure 9 and Figure 10As shown, when installing the transverse beam 2, the fixing part 4 can be placed in the installation chamber 11 first. At this time, the extension arm 18 is at the upper end of the guide part 13, and the lower end of the fixing part 4 is directly located in the middle of the installation chamber 11. The distance between the bottom surface inside the beam hole 5 and the bottom surface of the positioning part 3 is H1. The distance H1 can be set to be smaller to facilitate the installation of the fixing part 4. After the fixing part 4 is placed in the installation chamber 11, the transverse beam 2 is then moved downward so that the deformable arm 19 passes over the guide part 13. The outer wall of the deformable arm 19 is guided by the guide surface 22, causing it to shrink and deform into the contraction area 2, so that the locking part 14 enters the locking groove 20, and the limiting protrusion enters the limiting hole 26, thereby limiting the position of the fixing part 4 through the positioning part 3.

[0047] When the fixing member 4 is completely inserted into the installation chamber 11, the distance between the bottom surface of the beam hole 5 and the bottom surface of the positioning member 3 is H2, and then the second bolt 9 is used to connect the fixing portion 8 to the vertical beam 1. This can facilitate the alignment between the horizontal beam 2 and the vertical beam 1, and facilitate installation, improving installation efficiency.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
