Description

Technical Field

[0001] This utility model relates to the field of bridge deck clamping technology, and in particular to a retractable bridge deck clamping fixing structure. Background Technology

[0002] In bridge steel structure construction, the connection and fixing between the bridge deck and the main joists is a crucial step in ensuring the structural integrity and load-bearing capacity. Traditional fixing methods often use high-strength bolts for direct connection or on-site welding. While these methods can achieve basic connection functions, they reveal significant shortcomings when facing complex working conditions, frequent disassembly and assembly, or rapid construction requirements. Especially in segmental assembled bridges or projects requiring later maintenance and replacement of bridge decks, how to achieve rapid positioning, reliable clamping, and efficient locking of the bridge decks has become a core issue restricting construction efficiency and structural adaptability. Utility Model Content

[0003] This invention provides a retractable bridge deck clamp fixing structure, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A retractable bridge deck clamp fixing structure includes: Both channel steels have mounting holes, and pins are installed in the mounting holes of both channel steels. The connecting rod is placed in the gap between two channel steels and is rotatably connected to the channel steels through a through-hole pin. The slider is placed on the upper end of the channel steel, and the slider is rotatably connected to the end of the connecting rod away from the pin. Nuts are installed in the edge gap between the two channel steels; The main keel has its lower flange connected to the wedge-shaped surface on the slider, and moves downward along the wedge-shaped surface to push the slider to separate to both sides. The surface of the lower flange of the main keel is provided with anti-slip texture. The locking block is fixed to the side of the slider near the main keel. The locking block moves with the slider, and the main keel is fixed to the locking block and the studs. A connecting steel plate is attached to the side of the slider away from the channel steel, and the connecting steel plate is provided with holes that match the bolt holes of the slider; The screw passes through the bolt hole connecting the steel plate and the slider, and is threadedly connected to the nut.

[0005] Furthermore, a guide groove is provided at the bottom of the slider, which is adapted to the contour of the upper surface of the channel steel. The slider slides along the upper surface of the channel steel through the guide groove, and a wear-resistant coating is applied to the wedge-shaped surface of the slider.

[0006] Furthermore, the connecting rod is a telescopic elastic rod.

[0007] Furthermore, a reinforcing rib is welded between the nut and the channel steel. The reinforcing rib is triangular, and its two right-angled sides are fixedly connected to the outer wall of the nut and the side wall of the channel steel, respectively.

[0008] Furthermore, a fastener is threaded onto the end of the screw away from the nut, and the fastener is in contact with the side of the connecting steel plate away from the slider.

[0009] Furthermore, a positioning hole is provided at one end of the pin, and a positioning pin is inserted into the positioning hole. The length of the positioning pin is greater than the diameter of the pin.

[0010] Furthermore, a damping sleeve is fitted at the sliding connection of the connecting rod.

[0011] Furthermore, the holes on the connecting steel plate are oblong holes, and the length direction of the oblong holes is consistent with the sliding direction of the slider.

[0012] The following technical effects can be achieved through the technical solution of this utility model: Two channel steels provide a stable installation base, and pins in the mounting holes enable flexible rotational connection between the connecting rod and the channel steel, ensuring smooth linkage between the connecting rod and the slider. The connecting rod is placed in the gap between the two channel steels and rotates with the slider. In conjunction with the downward movement of the lower flange of the main keel along the wedge-shaped surface of the slider, it automatically pushes the slider to separate to both sides, improving installation convenience. The anti-slip texture on the surface of the lower flange of the main keel effectively increases the contact friction between the main keel and the wedge-shaped surface of the slider, ensuring the safety of installation operations. The locking block is fixed to the side of the slider near the main keel and moves synchronously with the slider. During the movement of the slider, it achieves clamping and positioning of the corresponding components, ensuring the positioning accuracy of the fixed structure. The connecting steel plate is attached to the side of the slider away from the channel steel, and its hole, which matches the bolt hole of the slider, ensures smooth insertion of the screw. After the screw is inserted, it is threadedly connected to the nut installed in the gap between the edges of the two channel steels, quickly completing the stable locking between the slider, the connecting steel plate, and the channel steel, reducing the space occupied by the fixed structure, and improving the overall structural stability after the bridge deck is fixed.

[0017] This application provides a retractable bridge deck clamp fixing structure, including: Two channel steels 1 are provided with mounting holes, and pins 2 are installed in the mounting holes of the two channel steels 1. The connecting rod 3 is placed in the gap between the two channel steels 1, and the connecting rod 3 is rotatably connected to the channel steel 1 through the through pin 2; Slider 4 is placed on the upper end of channel steel 1, and slider 4 is rotatably connected to the end of connecting rod 3 away from pin 2; Nut 5 is installed in the edge gap between the two channel steels 1; The lower flange of the main keel 6 is connected to the wedge-shaped surface on the slider 4, and moves downward along the wedge-shaped surface to push the slider 4 to separate to both sides. The surface of the lower flange of the main keel 6 is provided with anti-slip texture. The locking block 7 is fixed to the side of the slider 4 near the main keel 6. The locking block 7 moves with the slider 4, and the main keel 6, the locking block 7, and the studs are fixed together. The connecting steel plate 8 is attached to the side of the slider 4 away from the channel steel 1, and the connecting steel plate 8 is provided with holes that match the bolt holes of the slider 4; Screw 9 passes through the bolt hole connecting steel plate 8 and slider 4, and is threadedly connected to nut 5: The technical solution of this utility model provides a stable installation foundation through two channel steels 1. The pins 2 within the mounting holes enable flexible rotational connection between the connecting rod 3 and the channel steels 1, ensuring smooth linkage between the connecting rod 3 and the slider 4. The connecting rod 3 is placed in the gap between the two channel steels 1 and rotatably connected to the slider 4. In conjunction with the downward movement of the lower flange of the main keel 6 along the wedge-shaped surface of the slider 4, it automatically pushes the slider 4 to separate to both sides, improving installation convenience. The anti-slip texture on the surface of the lower flange of the main keel 6 effectively increases the contact friction between the main keel 6 and the wedge-shaped surface of the slider 4, ensuring the safety of installation operations. The locking block 7 is fixed to the side of the slider 4 near the main keel 6 and moves synchronously with the slider 4. During the movement of the slider 4, it achieves the locking and positioning of the corresponding parts, ensuring the positioning accuracy of the fixed structure. The connecting steel plate 8 is attached to the side of the slider 4 away from the channel steel 1. Its hole, which matches the bolt hole of the slider 4, ensures that the screw 9 can be smoothly inserted. After the screw 9 is inserted, it is threadedly connected to the nut 5 installed in the gap between the edges of the two channel steels 1, quickly completing the stable locking between the slider 4, the connecting steel plate 8 and the channel steel 1, reducing the space occupied by the fixed structure and improving the overall structural stability after the bridge deck is fixed.

[0018] During use, a guide groove is provided at the bottom of the slider 4. The guide groove is adapted to the contour of the upper surface of the channel steel 1. The slider 4 slides along the upper surface of the channel steel 1 through the guide groove. A wear-resistant coating is applied to the wedge-shaped surface of the slider 4. Through the technical solution of this utility model, the contour adaptation enables the slider 4 to form a precise guiding constraint when sliding along the upper surface of the channel steel 1 through the guide groove, effectively preventing the slider 4 from shifting laterally during the sliding process, ensuring that the rotational connection between the slider 4 and the connecting rod 3 away from the pin 2 remains smooth, thereby ensuring that the locking block 7 can accurately correspond to the part to be locked when it moves with the slider 4, improving the positioning accuracy of the fixed structure. The wear-resistant coating applied to the wedge-shaped surface of the slider 4 significantly enhances the wear resistance of the wedge-shaped surface.

[0019] In the above embodiment, the connecting rod 3 is a telescopic elastic rod; A damping sleeve is fitted at the sliding connection of link 3; Through the technical solution of this utility model, the connecting rod 3 is set as a telescopic elastic rod. When the lower flange of the main keel 6 pushes the slider 4 to separate to both sides, it adaptively adjusts its length through its own telescopic characteristics to ensure that the slider 4 slides smoothly along the upper surface of the channel steel 1, thereby ensuring that the locking block 7 can accurately move with the slider 4 to achieve locking and positioning of the corresponding parts. The elastic characteristics of the telescopic elastic rod provide auxiliary elastic force during the reset process of the slider 4, helping the slider 4 to quickly return to the initial position.

[0020] As a preferred embodiment of the above embodiment, a reinforcing rib 10 is welded between the nut 5 and the channel steel 1. The reinforcing rib 10 is triangular, and the two right-angled sides of the reinforcing rib 10 are fixedly connected to the outer wall of the nut 5 and the side wall of the channel steel 1, respectively. Through the technical solution of this utility model, the reinforcing rib 10 is structurally designed to be fixedly connected to the outer wall of the nut 5 and the side wall of the channel steel 1 by its two right-angled sides respectively. By utilizing the inherent structural stability of the triangle, the connection strength between the nut 5 and the channel steel 1 is enhanced. This avoids the problem of the nut 5 cracking or falling off at the weld due to the tightening force transmitted by the screw 9 when the screw 9 passes through the bolt hole of the connecting steel plate 8 and the slider 4 and is threadedly connected and locked to the nut 5. The triangular reinforcing rib 10 evenly distributes the force on the nut 5 to the side wall of the channel steel 1, reduces the local stress concentration at the connection between the nut 5 and the channel steel 1, and prevents the side wall of the channel steel 1 from deforming due to excessive local stress.

[0021] During use, the end of the screw 9 away from the nut 5 is threaded with a fastener 11, and the fastener 11 is in contact with the side of the connecting steel plate 8 away from the slider 4. Through the technical solution of this utility model, the fastener 11 is fitted to the side of the connecting steel plate 8 away from the slider 4. Based on the bolt hole of the screw 9 passing through the connecting steel plate 8 and the slider 4 and being threadedly connected to the nut 5, a two-way locking structure is formed. This prevents the screw 9 from loosening due to vibration and load changes during long-term use of the bridge deck, thus preventing threaded connection failure. After the fastener 11 is fitted to the connecting steel plate 8, the clamping force of the screw 9 on the connecting steel plate 8 is increased, making the connecting steel plate 8 fit the slider 4 more tightly, thereby enhancing the connection stability between the slider 4 and the channel steel 1.

[0022] In the above embodiment, a positioning hole is provided at one end of the pin 2, and a positioning pin 12 is inserted into the positioning hole. The length of the positioning pin 12 is greater than the diameter of the pin 2. Through the technical solution of this utility model, the structural design of the positioning pin 12 protruding from both sides of the pin 2 forms a reliable axial limiting constraint on the pin 2, preventing the pin 2 from moving axially in the mounting holes of the two channel steels 1, which would cause misalignment in the rotational connection between the connecting rod 3 and the channel steel 1. This structure avoids the pin 2 from falling out of the mounting holes of the two channel steels 1 due to vibration and load impact during long-term use of the bridge deck.

[0023] During use, the holes on the connecting steel plate 8 are oblong holes, and the length direction of the oblong holes is consistent with the sliding direction of the slider 4; Through the technical solution of this utility model, the length direction of the elongated hole is consistent with the sliding direction of the slider 4, which effectively compensates for the slight displacement of the bolt hole position during the sliding of the slider 4 along the upper surface of the channel steel 1, avoids the problem of the screw 9 being difficult to pass through due to the misalignment of the hole position after the installation position deviation of the slider 4 in the traditional round hole, and significantly improves the installation efficiency.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
