Description

Technical Field

[0001] This utility model relates to the technical field of lead screws, and more specifically, to a tie rod that also serves as an internal support structure for the side formwork of a culvert. Background Technology

[0002] Applications of Screw Rods: Screw rods are common engineering components with a wide range of uses, serving functions such as tensile strength, fixation, and connection depending on the application scenario. Side formwork internal supports are key structures used to fix the formwork on both sides and resist the lateral pressure of concrete pouring, especially widely used in culverts, bridge piers, retaining walls, and other projects. The core function of screw rods is to withstand tensile forces and, through proper design, achieve structural fixation, load transfer, or system support. Their materials (steel, aluminum alloy, carbon fiber, etc.) and forms (bolts, steel strands, anchor cables, etc.) vary depending on the application, but all must meet the requirements of strength, stiffness, and durability. In engineering projects, it is necessary to select the appropriate type of screw rod based on the load conditions and environmental conditions, and ensure safety and reliability through calculations.

[0003] The side formwork reinforcement of culverts often combines threaded rods with materials such as steel pipes and timber. After safety calculations, a support system is erected. However, the construction environment of culverts is relatively small. The side formwork support near the outside often cannot be installed strictly according to the technical plan requirements due to site conditions, and the construction efficiency is low.

[0004] Therefore, a tie rod that also serves as an internal support structure for the culvert side formwork is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a tie rod that also serves as an internal support structure for the culvert side formwork, 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 tie rod that also serves as an internal support structure for the side formwork of a culvert, comprising a template, a secondary keel installed on one side of the template, a main keel installed on the side of the secondary keel away from the template, and an adjustment mechanism installed at the overlap of the main keel and the secondary keel, a keel installed on one side of the template, and a fixing mechanism installed at both ends of the keel.

[0007] Preferably, the adjusting mechanism includes a rotating block, a first stop block, a locking block, and a first isolation block. The locking block has a C-shaped structure, and an isolation block is installed on one side of the locking block groove, while the first stop block is installed on the side of the locking block away from the isolation block.

[0008] Preferably, the isolation block has main keels installed on both sides and installed separately by the isolation block, and the groove of the locking block partially surrounds one side of the two main keels.

[0009] Preferably, the fixing mechanism includes a fixing block, a second stop block, a second isolation block, and a fixing plate. The fixing plate is installed on one side of the template, the second isolation block is installed on the side of the fixing plate away from the template, the fixing block is installed on one side of the second isolation block, and the second stop block is installed on the side of the fixing block away from the second isolation block.

[0010] Preferably, the fixing block and the fixing plate are provided with slots at corresponding positions, and the size of the slots matches the cross-sectional size of the narrow side of the keel.

[0011] Preferably, a lead screw is installed on one side of the rotating block. The lead screw passes through the rotating block, the first stop block, the locking block, the first isolation block inside the adjusting mechanism, the fixing block, the second stop block, the second isolation block, the fixing plate, and the template inside the fixing mechanism in sequence. The lead screw is threadedly connected to the rotating block, the first stop block, the locking block, the first isolation block inside the adjusting mechanism, and the fixing block, the second stop block, the second isolation block, and the fixing plate inside the fixing mechanism.

[0012] Preferably, the portion of the lead screw that overlaps with the template has a smooth shaft.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] Compared with existing technologies, this tie rod also serves as an internal support structure for the culvert side formwork. By changing the way the formwork is reinforced on the outside of the culvert and using a combination of fasteners and single keels, the required operating space is reduced, making it applicable to construction in narrow environments.

[0015] Compared with existing technologies, this tie rod also serves as an internal support structure for the culvert side formwork.

[0022] Example

[0023] As attached Figures 1 to 4 The tie rod shown serves as an internal support structure for the side formwork of a culvert. It includes a template 1, a secondary keel 2 installed on one side of the template 1, a main keel 3 installed on the side of the secondary keel 2 away from the template 1, and an adjustment mechanism 4 installed at the overlap of the main keel 3 and the secondary keel 2. A keel 5 is installed on one side of the template 1, and a fixing mechanism 6 is installed at both ends of the keel 5. The template 1 is fixed on one side of the side formwork by the combination of the main keel 3 and the secondary keel 2, and the template 1 is fixed on the other side of the side formwork by the combination of the fixing mechanism 6 and the keel 5.

[0024] The adjustment mechanism 4 includes a rotating block 401, a first stop block 402, a locking block 403, and a first isolation block 404. The locking block 403 has a C-shaped structure, and the isolation block 404 is installed on one side of the groove of the locking block 403. The first stop block 402 is installed on the side of the locking block 403 away from the isolation block 404. The main keel 3 is installed on both sides of the isolation block 404 and is installed separately by the isolation block 404. The groove of the locking block 403 partially surrounds one side of the two main keels 3. When the first stop block 402 and the isolation block 404 are rotated, the rotation of the first stop block 402 drives the locking block 403 to move along the rod of the screw 7. The movement of the locking block 403 makes the main keel 3 and the secondary keel 2 close to the template 1, so that the template is subjected to pressure from the main keel 3 and the secondary keel 2, thus fixing the template. At the same time, the isolation block 404 ensures that the lateral displacement of the main keel 3 is reduced and prevents the main keel 3 from shifting.

[0025] The fixing mechanism 6 includes a fixing block 601, a second stop block 602, a second isolation block 603, and a fixing plate 604. The fixing plate 604 is installed on one side of the template 1. The second isolation block 603 is installed on the side of the fixing plate 604 away from the template 1. The fixing block 601 is installed on one side of the second isolation block 603. The second stop block 602 is installed on the side of the fixing block 601 away from the second isolation block 603. The fixing block 601 and the fixing plate 604 are provided with corresponding slots, and the size of the slots matches the cross-sectional size of the narrow side of the keel 5. When the second stop block 602 is rotated, the second stop block 602 rotates and drives the fixing block 601 to move along the rod of the screw 7, squeezing the keel 5 to move towards the side of the template 1, thereby fixing the template 1. At the same time, the slots provided on the fixing block 601 and the fixing plate 604, which are the same as the cross-sectional size of the narrow side of the keel 5, fix the two sides of the keel 5 so that it does not shift.

[0026] A lead screw 7 is installed on one side of the rotating block 401. The lead screw 7 passes through the rotating block 401, the first stop block 402, the locking block 403, the first isolation block 404 inside the adjusting mechanism 4, and the fixing block 601, the second stop block 602, the second isolation block 603, the fixing plate 604 and the template 1 inside the fixing mechanism 6 in sequence. The lead screw 7 is threadedly connected to the rotating block 401, the first stop block 402, the locking block 403, the first isolation block 404 inside the adjusting mechanism 4 and the fixing block 601, the second stop block 602, the second isolation block 603 and the fixing plate 604 inside the fixing mechanism 6. Rotating the rotating block 401 causes the lead screw 7 to pass through the interior of the adjusting mechanism 4, the template 1 and the fixing mechanism 6 in sequence, so that the pull rod forms a whole. Rotating the rotating block 401 in the opposite direction can disengage the lead screw 7 from the adjusting mechanism 4, the template 1 and the fixing mechanism 6, and quickly remove each component.

[0027] Among them, the part of the lead screw 7 that overlaps with the template 1 has a smooth shaft, which makes it easier to pass through the template 1 and also makes disassembly more convenient.

[0028] The working process of this utility model is as follows: When in use, firstly, rotate the rotating block 401 so that the lead screw 7 passes through the interior of the adjusting mechanism 4, the template 1 and the fixing mechanism 6 in sequence, so that the pull rod forms a whole.

[0029] Then, by simultaneously rotating the first stop block 402 and the isolation block 404, the rotation of the first stop block 402 drives the locking block 403 to move along the shaft of the lead screw 7. The movement of the locking block 403 brings the main keel 3 and the secondary keel 2 closer to the template 1, so that the template is subjected to pressure from the main keel 3 and the secondary keel 2, thus fixing the template. At the same time, the isolation block 404 ensures that the lateral displacement of the main keel 3 is reduced, preventing the main keel 3 from shifting.

[0030] Next, rotate the second stop 602. The rotation of the second stop 602 drives the fixing block 601 to move along the rod of the screw 7, squeezing the keel 5 to move toward the side of the template 1, thereby fixing the template 1. At the same time, the fixing block 601 and the fixing plate 604 are provided with slots with the same cross-sectional size as the narrow side of the keel 5 to fix the two sides of the keel 5 so that it does not shift.

[0031] Finally, by simultaneously applying the adjusting mechanism 4 and the fixing mechanism 6 to both sides of the template 1 to fix the template 1, and rotating the rotating block 401 in the opposite direction, the lead screw 7 can be disengaged from the adjusting mechanism 4, the template 1 and the fixing mechanism 6, allowing for quick disassembly of each component and improving efficiency.
