Technical Field

[0001] This utility model relates to the field of steel structure installation technology, specifically a self-locking steel structure splicing device for building engineering. Background Technology

[0002] Steel structures in building construction are structural systems that use steel as the main load-bearing component. They possess advantages such as lightweight and high strength, good seismic performance, short construction period, and flexible design, and are widely used in large factories, stadiums, and high-rise buildings. Currently, most steel structures are fixed using bolts or welding during installation. When connecting steel structures, especially for larger steel beams, cranes are typically used to lift the beams, align them in the installation position, and tighten the bolts using wrenches and other tools. Due to the significant weight of the steel beams, positional adjustments are inconvenient during installation, and the need for crane lifting throughout this process consumes time and manpower, impacting normal work efficiency. Therefore, a self-locking splicing device needs to be designed to facilitate the connection between steel beams and columns. Utility Model Content

[0003] To address the aforementioned shortcomings, this utility model provides a self-locking steel structure splicing device for building engineering, which enables rapid and stable connection between steel beams and columns, has a self-locking function, facilitates installation, and improves construction efficiency.

[0004] To achieve the above objectives, the technical solution provided by this utility model is a self-locking steel structure splicing device for building engineering, comprising a first fixing plate and a second fixing plate, both of which are vertically arranged. A groove is provided in the middle of the second fixing plate, and a guide limiting block is fixedly connected to the surface of the groove. A clamping device is fixedly connected to the top of the guide limiting block. A support plate perpendicular to the first fixing plate is fixedly connected to one side of the first fixing plate, and a limiting seat is provided on one side of the top of the support plate. After the guide limiting block is vertically inserted into the limiting seat, the clamping device engages with the limiting seat.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] Example 1: Please refer to Figure 1-6 This utility model provides a technical solution: a self-locking steel structure splicing device for building engineering, including a first fixing plate 1 and a second fixing plate 2. The first fixing plate 1 and the second fixing plate 2 are both vertically arranged. One side of the first fixing plate 1 and the second fixing plate 2 is located in the same vertical plane. The surfaces of the first fixing plate 1 and the second fixing plate 2 are provided with fixing holes, and the first fixing plate 1 and the second fixing plate 2 are fixed to one side of the column through the fixing holes on the surface.

[0020] The second fixing plate 2 has a groove 3 in the middle. A guide limiting block 4 is fixedly connected to the surface of the groove 3. The two sides of the guide limiting block 4 and the position near the bottom are set as slopes. A clamping device 5 is fixedly connected to the top of the guide limiting block 4. A support plate 6 perpendicular to the first fixing plate 1 is fixedly connected to one side of the first fixing plate 1. A rib plate 9 is fixedly connected between one side of the first fixing plate 1 and the bottom of the support plate 6 to improve the stability of the support plate 6. The support plate 6 and the rib plate 9 are fixed by welding.

[0021] A connecting wing plate 8 is fixedly connected to one side of the second fixing plate 2. The surface of the connecting wing plate 8 is provided with mounting holes. There is a pair of connecting wing plates 8 arranged symmetrically. The steel beam is installed between the two connecting wing plates 8 and fixed with bolts, so that the second fixing plate 2 is fixed to one side of the steel beam. During installation, a notch that matches the groove 3 needs to be cut at one end of the steel beam to ensure that one side of the second fixing plate 2 is close to one end of the steel beam.

[0022] A limiting seat 7 is provided on one side of the top of the support plate 6. After the guide limiting block 4 is inserted vertically downward into the limiting seat 7, the clamping device 5 engages with the limiting seat 7. The engagement of the clamping device 5 with the limiting seat 7 restricts the longitudinal movement of the first fixing plate 1, thereby achieving the fixation of the steel beam.

[0023] The limiting seat 7 includes a rectangular block 71. The surface of the rectangular block 71 is provided with a first connecting groove 72 and a second connecting groove 73. The top two sides of the first connecting groove 72 are connected to the bottom of the second connecting groove 73 through inclined surfaces. The two sides of the second connecting groove 73 are also provided with guide grooves 74, and the bottom of the guide grooves 74 is provided with a locking hole 75.

[0024] The clamping device 5 includes a housing 51, inside which a cavity 52 is provided. Slider 53 is symmetrically arranged on both sides of the cavity 52. ​​A slide rod 56 is fixedly connected to one side of the slider 53. One end of the slide rod 56 extends to the outside of the housing 51 and is fixedly connected to a locking block 57. The bottom sides of the locking block 57 are set as inclined surfaces. A connecting plate 54 is fixedly connected to the middle of the bottom of the cavity 52. ​​Guide rods 55 are fixedly connected to both sides of the connecting plate 54. The slider 53 is slidably connected to the inner wall of the cavity 52 and the surface of the guide rods 55. A return spring 58 is provided between one side of the connecting plate 54 and the slider 53.

[0025] During installation, the guide limit block 4 first enters the second connecting groove 73. Through the inclined surface of the guide limit block 4 and the inclined surfaces on both sides of the top of the first connecting groove 72, the guide limit block 4 continues to enter the first connecting groove 72. At this time, the locking block 57 enters the guide groove 74. Through the action of the guide groove 74, the locking block 57 moves along the length direction of the guide rod 55 towards the cavity 52. ​​The return spring 58 is compressed. As the steel beam continues to descend, the guide limit block 4 falls into the bottom of the first connecting groove 72. At this time, the locking block 57 enters the locking hole 75 under the action of the spring 58, realizing the locking.
