Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, specifically to a steel structure connector for road and bridge construction. Background Technology

[0002] Currently, in the process of road and bridge construction, it is often necessary to use steel structure connectors to assemble and connect steel columns and steel pipes. Specifically, the steel columns are set vertically, while the steel pipes are distributed horizontally. Then, during construction, when the end of the steel pipe close to the steel column is connected to the steel column through the steel structure connector, the steel pipe can be assembled onto the steel column.

[0003] In existing technology, a ring-shaped clamp is used to wrap the steel pipe and bolts are used to fix it to the outer wall of the steel pipe. At the same time, the bottom of the clamp is fixed to the outer wall of the steel column with a vertical plate, thereby fixing the steel pipe and the steel column together and making them stable during use.

[0004] However, in actual use, due to the high strength of the supports between bridges, deformation of the connectors can occur under long-term support, making it inconvenient to disassemble and replace the connectors and reducing work efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a steel structure connector for road and bridge construction, which solves the problem that in actual use, due to the high support strength between bridges, the connectors may deform under long-term support, making disassembly and replacement inconvenient and reducing work efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a steel structure connector for road and bridge construction, comprising a fixed frame, a connecting plate fixedly connected to the top of the fixed frame, a clamping plate fixedly connected to the top of the connecting plate, a protrusion fixedly connected to the inner wall of the clamping plate, an installation block fixedly connected to the top of the clamping plate, an installation groove formed on the top of the installation block, a threaded rod inserted into the inner wall of the installation groove, a locking block fixedly connected to one end of the threaded rod extending outside the installation groove, the outer wall of the locking block abutting against the outer wall of the installation block, and an adjustment device installed on the outer wall of the threaded rod.

[0007] Preferably, the adjusting device includes a fixed cylinder, the inner wall of which is threadedly connected to the outer wall of the threaded rod, and a rhomboid block is fixedly connected to the outer wall of the fixed cylinder.

[0008] Preferably, a stop bar is provided above the threaded rod, the outer wall of the stop bar is slidably engaged with the top of the mounting block, a slot is provided on the inner wall of the threaded rod, a plug is inserted into the inner wall of the slot, and the outer wall of the plug is fixedly connected to the inner wall of the threaded rod.

[0009] Preferably, a fixing block is fixedly connected to one side of the outer wall of the fixing frame, a plug rod is fixedly connected to the outer wall of the fixing block, a limit block is sleeved on the outer wall of the plug rod, and the outer wall of the limit block is fixedly connected to the other side of the outer wall of the fixing frame.

[0010] Preferably, a screw is inserted into the inner wall of the fixing frame, and an arc-shaped block is fixedly connected to the inner wall of the fixing frame.

[0011] Beneficial effects

[0012] This utility model provides a steel structure connector for road and bridge construction. It has the following advantages: This steel structure connector for road and bridge construction, through the cooperation of clamping plates, threaded rods, and mounting grooves, utilizes the snap-fit ​​property between the threaded rods and mounting grooves to facilitate disassembly of the fixing device. Furthermore, under the action of the adjustment device, it ensures the overall structural fixation of the bridge. This solves the problem that when the support strength between bridge sections is high, deformation of the connectors can occur under prolonged support, leading to inconvenience in disassembly and replacement and reduced work efficiency.

[0013] By using the combination of the fixed frame, the insert rod, and the fixed block, the insert rod is inserted into the limit block when installing the fixed frame, ensuring the stability of the fixed frame during installation. This makes it convenient to fix the support device to the column and beam, and solves the problem that the fixed frame needs to be carefully adjusted when installing the connector, which leads to unstable support of the connector to the column and beam.

[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] In actual use, due to the high strength of the supports between bridges, deformation of the connectors can occur under long-term support, making it inconvenient to disassemble and replace the connectors and reducing work efficiency.

[0021] In view of this, the present invention provides a steel structure connector for road and bridge construction, which solves the problem that in actual use, due to the large support strength between bridges, the connectors will deform under long-term support, which will make it inconvenient to disassemble and replace the connectors and reduce work efficiency.

[0022] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0023] Example 1: By Figure 1-4 It is known that a steel structure connector for road and bridge construction includes a fixed frame 1, a connecting plate 3 fixedly connected to the top of the fixed frame 1, a clamping plate 2 fixedly connected to the top of the connecting plate 3, a protrusion 10 fixedly connected to the inner wall of the clamping plate 2, an installation block 4 fixedly connected to the top of the clamping plate 2, an installation groove 13 opened on the top of the installation block 4, a threaded rod 8 inserted into the inner wall of the installation groove 13, a locking block 14 fixedly connected to one end of the threaded rod 8 extending to the outside of the installation groove 13, the outer wall of the locking block 14 abutting against the outer wall of the installation block 4, and an adjustment device installed on the outer wall of the threaded rod 8.

[0024] In the specific implementation process, it is worth noting that the fixing frame 1 is set to be symmetrical on both sides and the two are fixed together by bolts, so that the connecting component fixes the crossbeam and the column together. Moreover, the clamping plate 2 is set to be a semi-circular plate that is symmetrical on both sides, so that the crossbeam can be clamped and the crossbeam and the column can be connected together. When using the clamping plate 2 to fix the crossbeam, the threaded rod 8 is inserted into the mounting groove 13 on the top of the mounting block 4, and under the action of the two side clamping blocks 14, the two clamping plates 2 are fixed to the crossbeam. This ensures that the connecting component fixes the crossbeam and the column. The clamping plate 2 and the fixing frame 1 are made of steel to ensure that the connecting component fixes the column and the crossbeam. Under the action of the adjustment device, the clamping force of the clamping plate 2 on the crossbeam can be adjusted. At the same time, even if the connecting component is deformed, the threaded rod 8 can be pulled out from the mounting groove 13, which makes disassembly more convenient.

[0025] Furthermore, the adjusting device includes a fixed cylinder 9, the inner wall of which is threadedly connected to the outer wall of the threaded rod 8, and a rhomboid block 11 is fixedly connected to the outer wall of the fixed cylinder 9;

[0026] In the specific implementation process, it is worth noting that the threaded rod 8 is set as a column with a semi-circular cross-section and has threads on its outer arc surface. When the rectangular cross-sections of the two threaded rods 8 come into contact, they will form a complete cylinder, and the threads on the outer walls of the two can be connected together. The inner wall of the fixed cylinder 9 has a corresponding internal thread. When the fixed cylinder 9 rotates, the two threaded rods 8 will move in opposite directions on the inner wall of the fixed cylinder 9, thereby causing the threaded rod 8 to drive the clamping block 14 to press against the outer wall of the mounting block 4, so that the clamping plate 2 is fixed on the crossbeam.

[0027] Furthermore, a stop bar 12 is provided above the threaded rod 8. The outer wall of the stop bar 12 is slidably engaged with the top of the mounting block 4. A slot 18 is provided on the inner wall of the threaded rod 8. A plug 17 is inserted into the inner wall of the slot 18. The outer wall of the plug 17 is fixedly connected to the inner wall of the threaded rod 8.

[0028] In the specific implementation process, it is worth noting that a sliding groove is provided on the top of the mounting block 4, which allows the stop bar 12 to be inserted into the top of the mounting block 4, so that the threaded rod 8 is stable inside the slot 18. When the threaded rod 8 moves, the insert block 17 will move in the slot 18 opened on the inner wall of the threaded rod 8. This ensures that the threaded rod 8 is stable when it moves and ensures that the threaded rod 8 will not deviate when it moves when the fixed cylinder 9 rotates.

[0029] Example 2: From Figure 1-4 It can be seen that a fixing block 5 is fixedly connected to one side of the outer wall of the fixing frame 1, a plug rod 16 is fixedly connected to the outer wall of the fixing block 5, a limit block 6 is sleeved on the outer wall of the plug rod 16, and the outer wall of the limit block 6 is fixedly connected to the other side of the outer wall of the fixing frame 1.

[0030] In the specific implementation process, it is worth noting that when the shape of the insertion rod 16 is a rectangular column, the insertion rod 16 will be inserted into the inner wall of the limiting block 6 when the fixing frame 1 is installed, so that the fixing frame 1 is aligned during installation and the connector is stable when fixing the beam and the column.

[0031] Furthermore, a screw 7 is inserted into the inner wall of the fixed frame 1, and an arc-shaped block 15 is fixedly connected to the inner wall of the fixed frame 1;

[0032] In the specific implementation process, it is worth noting that when installing the connector, the screw 7 is inserted into the inside of the fixed frame 1 and passes through the column. This makes the fixed frame 1 stable when it is fixed to the outer wall of the column. At the same time, the arc-shaped block 15 set on the inner wall of the fixed frame 1 can increase the friction between the fixed frame 1 and the column, thereby making the connector stable when fixing the column and the beam.

[0033] Although embodiments of the present invention 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 the present invention, the scope of which is defined by the appended claims and their equivalents.
