Description

Technical Field

[0001] The utility model relates to the technical field of bridge steel structures, in particular to a bridge steel structure connecting fastener. Background Art

[0002] The connection fasteners of bridge steel structures are key components in bridge construction. Their main function is to firmly connect the various steel structure components of the bridge to ensure the overall stability and bearing capacity of the bridge. Traditional bridge steel structure connection fasteners are usually connected by welding or bolts. Although these methods have certain reliability, they have some shortcomings in practical applications.

[0003] Although the bolt connection method has good disassembly performance, it is often necessary to fine-tune the connection position in complex construction sites due to terrain restrictions and construction accuracy requirements. The traditional bolt connection method is cumbersome during the fine-tuning process and often requires disassembly and reinstallation, which is not only time-consuming and labor-intensive, but may also affect the construction progress and project quality. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a bridge steel structure connection fastener.

[0005] The utility model is implemented by the following technical scheme: a bridge steel structure connecting fastener, including a mounting base plate, the upper surface of the mounting base plate is provided with a sliding groove, the interior of the sliding groove is slidably connected with a sliding block, the upper surface of the sliding block is fixedly connected with a supporting steel beam, the upper surface of the mounting base plate is fixedly connected with a side clamping plate, and the outer surface of the side clamping plate is provided with a plurality of positioning holes.

[0006] Through the above technical solution, the design of the sliding groove and the sliding block allows the sliding block to move in the sliding groove, so that the position of the supporting steel beam can be adjusted to adapt to different construction requirements and fine-tune the alignment. The side clamp is fixed to the first pin through the positioning hole, which increases the stability of the overall structure. The design of the positioning hole allows the first pin to pass through to ensure that the position of the supporting steel beam will not move relative to each other.

[0007] As a further improvement of the above solution, the support steel beam is slidably connected to the upper surface of the mounting base plate via a sliding block, and a connecting sleeve is fixedly connected to the upper surface of the support steel beam.

[0008] Through the above technical solution, by the free sliding of the sliding block in the sliding groove, the construction workers can accurately adjust the position of the supporting steel beam to ensure that the supporting steel beam can be accurately aligned and adapt to various construction conditions and requirements. In addition, this adjustability greatly reduces the need to disassemble and reinstall the steel beam due to installation errors, significantly improving construction efficiency and reducing labor intensity.

[0009] As a further improvement of the above solution, a circular hole is opened inside the connecting sleeve, a first latch is inserted into the circular hole, and the first latch passes through the positioning hole on the surface of the side card plate.

[0010] Through the above technical solution, the latch connection provides good disassembly performance, and the first latch can be easily removed when necessary, thereby separating the side card plate and the supporting steel beam, making it convenient for structural adjustment or component replacement.

[0011] As a further improvement of the above solution, an assembly hole is provided on the outer surface of the supporting steel beam, and a second latch is inserted into the interior of the assembly hole.

[0012] Through the above technical solution, after the second pin is inserted into the assembly hole, it can effectively fix the relative positions of the two supporting steel beams to ensure that they will not move relative to each other. When position adjustment is required, the two supporting steel beams can be easily separated by simply pulling out the second pin, and then the positions of the supporting steel beams can be adjusted, thereby simplifying the work flow.

[0013] As a further improvement of the above solution, both ends of the first latch and the second latch are threadedly connected with hexagonal bolts.

[0014] As a further improvement of the above solution, a bottom reinforcement block is fixedly connected to the surface of the mounting base plate.

[0015] Through the above technical solution, the bottom reinforcement block can significantly enhance the structural strength of the mounting base plate, prevent it from deformation or cracking under load, and help disperse the stress concentration on the mounting base plate, especially in areas with greater stress, effectively extending its service life.

[0016] As a further improvement of the above solution, the number of the mounting base plate and the side clamping plate is set to two, which are respectively located on both sides of the bottom reinforcement block.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model sets an installation base plate, and through the cooperation of the sliding block and the sliding groove, the supporting steel beam can be fine-tuned on the installation base plate according to actual needs to ensure its precise alignment with the bridge design requirements. The fine-tuning function makes it possible to flexibly adapt to the needs of bridge construction under different terrain conditions in complex and changeable construction environments, without the need for time-consuming and labor-intensive disassembly and reinstallation due to slight errors in initial positioning, thereby improving the efficiency and quality of bridge construction. In addition, through the dual fixing mechanism of the first pin and the second pin, and the reinforcement effect of the bottom reinforcement block, the tensile and compressive properties of the connecting fasteners are further improved, thereby ensuring the long-term stability and service life of the bridge steel structure.

After the supporting steel beams 4 are aligned, for the two supporting steel beams 4 that need to be connected, insert the second pin 10 into the assembly hole 9 on the outer surface thereof. The second pin 10 should pass through the assembly holes 9 of the two supporting steel beams 4.

Subsequently, the first pin 8 is inserted into the positioning hole 6 and the circular hole inside the connecting sleeve 7 using the positioning hole 6 on the side clamp 5. The first pin 8 passes through the positioning holes 6 on the side clamps 5 on both sides. The two ends of the first pin 8 are fastened using hexagonal bolts to enhance the fixing effect of the first pin 8 and ensure the stable connection between the supporting steel beam 4 and the side clamp 5. The bottom reinforcement block 11 is usually made of high-strength material and is firmly connected to the mounting base plate 1 by welding or other fastening methods, thereby improving the rigidity and strength of the overall structure.
