Description

Technical Field

[0001] This utility model relates to the field of railway construction technology, specifically to a reinforced fixing structure for railway steel mesh. Background Technology

[0002] Railway tracks, tunnels, roadbeds and other structures need to withstand train loads, natural environmental erosion and geological changes for a long time, which places extremely high demands on structural stability and durability. As an important reinforcing material for railway concrete structures, the fixing effect of steel mesh directly affects the overall performance of the structure.

[0003] A search revealed a utility model patent with Chinese patent publication number CN215519508U, which discloses a fixing device for steel mesh, including a support frame, a fixing structure fixedly connected to the support frame, and the fixing structure for clamping the nodes of the steel mesh.

[0004] The aforementioned device uses two clips to secure the steel mesh. However, after the mesh is placed, it is necessary to use clips to connect the two. To ensure the stability of the connection, the clips need to have sufficient elasticity. In actual use, this consumes a lot of the operator's physical strength, and there is room for improvement. Utility Model Content

[0005] The purpose of this utility model is to provide a reinforced fixing structure for steel mesh used in railways, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a reinforced fixing structure for railway steel mesh, comprising a support structure and a heightening structure. The support structure is located at the top of the heightening structure. The support structure includes two bottom support parts and a top receiving part. The receiving part is located on top of the two support parts. Two fixing components are installed on the top of the receiving part. Each fixing component includes a connecting sleeve fixedly fitted on the top of the receiving part. A vertically arranged receiving clip is fixedly connected to the top of the connecting sleeve. Both ends of the top of the receiving clip are threaded with an inclined fixing bolt, and the two fixing bolts are symmetrically arranged. The steel mesh body is placed inside the receiving clip. The ends of the two fixing bolts that are close to each other are provided with round heads, and both round heads are in contact with the steel mesh body.

[0007] As a further preferred embodiment of this technical solution, a clearance portion is provided at the middle position of the receiving part, and the transverse reinforcement portion of the steel mesh body is located exactly inside the clearance portion.

[0008] This method achieves rapid fixation of the reinforcing mesh while ensuring sufficient stability of both the mesh and the supporting structure. The operation requires minimal physical exertion, indirectly improving work efficiency. After placing the reinforcing mesh, turn the knob on the fixing bolt. The bolt rotates along the receiving clip towards the mesh body, and the bolt tip will then adhere to the outer wall of the transverse reinforcement of the mesh. Further turning the bolt compresses the transverse reinforcement against the inner wall of the receiving clip, restricting upward movement of the mesh. The mesh and supporting structure are then firmly fixed together. The operation is convenient and quick, requiring minimal physical exertion.

[0009] As a further preferred embodiment of this technical solution, the height-increasing structure includes a bottom support portion two and two top receiving portions two. Both receiving portions two are disposed on the top of the support portion two. Both top of the support portion two are provided with two receiving portions. The bottom of the support portion two is provided with four sleeve portions two that are adapted to the four receiving portions. The bottom of both support portions one is provided with two sleeve portions one that are adapted to the receiving portions.

[0010] If the height of the support structure is insufficient, a heightening structure can be placed at the bottom of the support structure beforehand. Then, the fitting part at the bottom of the support structure can be fitted onto the receiving part at the top of the heightening structure. With the receiving part and the fitting part restricting each other, the positions of the support structure and the heightening structure will not move relative to each other at will. If the height is still insufficient, another heightening structure can be placed at the bottom of the heightening structure. The fitting part of the upper heightening structure can be fitted onto the outside of the receiving part of the lower heightening structure. With the cooperation of the receiving part and the fitting part, the positions of the two heightening structures can also be kept relatively fixed.

[0011] As a further preferred embodiment of this technical solution, the two ends of the receiving part are vertically arranged and contact the two top walls of the supporting part.

[0012] As a further preferred embodiment of this technical solution, each end of the two supporting structures is provided with a receiving ring, and the two receiving rings are slidably inserted into the same reinforcing rod.

[0013] As a further preferred embodiment of this technical solution, the fixing bolt is a self-locking bolt.

[0014] As a further preferred embodiment of this technical solution, both the support structure and the heightening structure are made of Q steel.

[0015] This utility model provides a reinforced fixing structure for steel mesh used in railways, which has the following beneficial effects:

[0016] (1) By setting a fixing component, this utility model can achieve the purpose of quickly fixing the steel mesh while ensuring that the state of the steel mesh and the fixing structure is stable enough. Moreover, the operation process does not require too much physical strength, thereby indirectly improving work efficiency. After the steel mesh body is placed, turn the knob end of the fixing bolt. The fixing bolt rotates and moves closer to the steel mesh body along the receiving clip. Then the end of the fixing bolt will fit against the outer wall of the horizontal bar of the steel mesh body. When the fixing bolt is turned further, the fixing bolt can squeeze the horizontal bar of the steel mesh body tightly against the inner wall of the receiving clip. The fixing bolt can also restrict the upward movement of the steel mesh body. The steel mesh body and the supporting structure will be firmly fixed together. The operation process is convenient and quick, without requiring too much physical strength.

[0017] (2) By setting up a height-increasing structure, if the height of the support structure is insufficient, a height-increasing structure can be placed at the bottom of the support structure in advance. Then, the sleeve part at the bottom of the support structure is placed on the receiving part at the top of the height-increasing structure. With the receiving part and the sleeve part restricting each other, the positions of the support structure and the height-increasing structure will not move relative to each other at will. If the height is still insufficient, another height-increasing structure can be placed at the bottom of the height-increasing structure. The sleeve part of the upper height-increasing structure can be placed outside the receiving part of the lower height-increasing structure. With the cooperation of the receiving part and the sleeve part, the positions of the two height-increasing structures can also be kept relatively fixed. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figure 2 and Figure 4 As shown, in this embodiment, the reinforced fixing structure of the railway steel mesh includes a support structure 1 and a heightening structure 2. The support structure 1 is located on top of the heightening structure 2. The support structure 1 includes two bottom support parts 101 and a top receiving part 102. The receiving part 102 is located on top of the two support parts 101. Two fixing components 6 are installed on the top of the receiving part 102. The fixing component 6 includes a connecting sleeve 601 fixedly sleeved on the top of the receiving part 102. A vertically arranged receiving clip 602 is fixedly connected to the top of the connecting sleeve 601. Both ends of the top of the receiving clip 602 are threaded with an inclined fixing bolt 603, and the two fixing bolts 603 are symmetrically arranged. The steel mesh body 3 is placed inside the receiving clip 602. The ends of the two fixing bolts 603 that are close to each other are provided with round heads 604, and both round heads 604 are in contact with the steel mesh body 3.

[0025] A clearance part 103 is provided in the middle of the receiving part 102. The horizontal bar part of the steel mesh body 3 is located inside the clearance part 103. Since there is a clearance part 103 at the top of the receiving part 102, the horizontal bar of the steel mesh body 3 can enter it, which can prevent the horizontal bar from affecting the normal placement of the steel mesh body 3. In addition, the clearance part 103 can prevent the steel mesh body 3 from moving left and right.

[0026] After placing the steel mesh body 3, turn the knob of the fixing bolt 603. The fixing bolt 603 rotates and moves closer to the steel mesh body 3 along the receiving clip 602. Then, the end of the fixing bolt 603 will fit against the outer wall of the horizontal bar of the steel mesh body 3. When the fixing bolt 603 is turned further, the fixing bolt 603 can squeeze the horizontal bar of the steel mesh body 3 tightly against the inner wall of the receiving clip 602. The fixing bolt 603 can also restrict the upward movement of the steel mesh body 3. The steel mesh body 3 and the supporting structure 1 will be firmly fixed together. The operation process is convenient and quick, without consuming too much physical strength.

[0027] like Figure 2 and Figure 3 As shown, the heightening structure 2 includes a bottom support part 201 and two top receiving parts 202. The two receiving parts 202 are both located on the top of the support part 201. The top of each of the two receiving parts 202 is provided with two receiving parts 203. The bottom of the support part 201 is provided with four sleeve parts 204 that are adapted to the four receiving parts 203. The bottom of each of the two support parts 101 is provided with two sleeve parts 104 that are adapted to the receiving parts 203.

[0028] The end of the receiving part 202 is vertically positioned and contacts the top wall of the supporting part 201, so that the supporting part 201 can provide support for the receiving part 202 and prevent the receiving part 202 from bending.

[0029] If the height of the support structure 1 is insufficient, a heightening structure 2 can be placed at the bottom of the support structure 1 beforehand. Then, the fitting part 104 at the bottom of the support structure 1 is fitted onto the receiving part 203 at the top of the heightening structure 2. With the receiving part 203 and the fitting part 104 mutually restricting each other, the positions of the support structure 1 and the heightening structure 2 will not move relative to each other at will. If the height is still insufficient, another heightening structure 2 can be placed at the bottom of the heightening structure 2. The fitting part 204 of the upper heightening structure 2 can be fitted onto the outside of the receiving part 203 of the lower heightening structure 2. With the cooperation of the receiving part 203 and the fitting part 204, the positions of the two heightening structures 2 can also be relatively fixed. When using the device, only the heightening structure 2 with the same height as required needs to be added. There is no need to customize a support structure 1 of other lengths, which is beneficial to improving the adaptability of the device.

[0030] like Figure 1 and Figure 2 As shown, each end of the two support structures 1 is provided with a receiving ring 4, and the two receiving rings 4 are slidably inserted with the same reinforcing rod 5, which can connect the adjacent support structures 1 and further increase the stability of the fixed structure.

[0031] like Figure 4 As shown, the fixing bolt 603 is a self-locking bolt, which can prevent the fixing bolt 603 from coming off the receiving clip 602 due to external force.

[0032] like Figure 1 and Figure 2 As shown, both the support structure 1 and the heightening structure 2 are made of Q345 steel, which has a yield strength of about 345MPa, much greater than that of Q235 steel. This allows the device to withstand greater loads and provides more reliable support for the steel reinforcement cage.

[0033] This utility model provides a reinforced fixing structure for steel mesh used in railways, and its specific working principle is as follows:

[0034] When the device is in operation, the longitudinal bars of the steel mesh body 3 are placed into the receiving clip 602. Under the restriction of the receiving clip 602, the steel mesh body 3 cannot move forward or backward. Because the top of the receiving part 102 has a clearance part 103, the transverse bars of the steel mesh body 3 can enter it, preventing the transverse bars from affecting the normal placement of the steel mesh body 3. Furthermore, the clearance part 103 prevents the steel mesh body 3 from moving left or right, thus ensuring that the steel mesh body 3 will not move horizontally. After the steel mesh body 3 is placed, the fixing... The knob end of the fixing bolt 603 rotates along the receiving clip 602 towards the steel mesh body 3. Then, the end of the fixing bolt 603 will fit against the outer wall of the transverse reinforcement of the steel mesh body 3. When the fixing bolt 603 is turned further, it can squeeze the transverse reinforcement of the steel mesh body 3 tightly against the inner wall of the receiving clip 602. The fixing bolt 603 can also restrict the upward movement of the steel mesh body 3. The steel mesh body 3 and the supporting structure 1 will be firmly fixed together. The operation process is convenient and quick, without consuming too much physical strength. If the height of the support structure 1 is insufficient, a heightening structure 2 can be placed at the bottom of the support structure 1 beforehand. Then, the fitting part 104 at the bottom of the support structure 1 is fitted onto the receiving part 203 at the top of the heightening structure 2. With the receiving part 203 and the fitting part 104 mutually restricting each other, the positions of the support structure 1 and the heightening structure 2 will not move relative to each other at will. If the height is still insufficient, another heightening structure 2 can be placed at the bottom of the heightening structure 2. The fitting part 204 of the upper heightening structure 2 can be fitted onto the outside of the receiving part 203 of the lower heightening structure 2. With the cooperation of the receiving part 203 and the fitting part 204, the positions of the two heightening structures 2 can also be relatively fixed. When using the device, only the heightening structure 2 with the same height as required needs to be added. There is no need to customize a support structure 1 of other lengths, which is beneficial to improving the adaptability of the device.

[0035] 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.
