Description

Technical Field

[0001] This utility model relates to the field of bridge column technology, and in particular to steel formwork for bridge columns. Background Technology

[0002] Bridge columns play a crucial role in bridge structures and are mainly divided into two types: piers and abutments. Piers are located in the middle of the bridge and support the bridge's span structure; while abutments are located at both ends of the bridge or near the riverbank, mainly supporting the connection between the bridge and the riverbank. Steel formwork is typically used during the pouring of concrete for bridge columns.

[0003] During the installation and assembly of steel formwork for bridge piers, sometimes the joints between the formwork panels are not secure enough, resulting in insufficient sealing of the joints. This can lead to grout leakage during concrete pouring, affecting the quality of the bridge pier construction. Furthermore, insufficient support of the steel formwork can cause it to shift during pouring, leading to problems in the pier construction. Therefore, effectively sealing the joints of the bridge pier formwork and ensuring the overall stability of the steel formwork support are crucial issues that need to be addressed in the design of bridge pier steel formwork. Utility Model Content

[0004] This utility model provides a steel formwork for bridge columns to solve the problems of insufficient tightness of the splicing joints between formworks and insufficient sturdiness of the steel formwork support for bridge columns.

[0005] This utility model solves the above-mentioned technical problems through the following technical solutions:

[0006] This utility model provides a steel formwork for bridge columns, including a bridge column formwork, and further comprising:

[0007] A supporting structure, which is installed on the bridge column formwork;

[0008] A fixed connection structure is provided at both ends of the bridge column formwork, and the connection structure provides a fixed connection between the bridge column formworks.

[0009] A clamping structure is provided on the connecting structure.

[0010] Preferably, the bridge column template has a "∟" shaped structure, and there are four bridge column templates, which are connected end to end to form a square structure.

[0011] In this technical solution, the spliced ​​bridge column formwork can be used for the casting of square bridge columns.

[0012] Preferably, the side wall of the bridge column template is provided with protruding horizontal ribs, which are evenly spaced along the vertical direction of the bridge column template. The side wall of the bridge column template is also provided with protruding vertical ribs, which are perpendicular to the horizontal ribs.

[0013] In this technical solution, the horizontal and vertical ribs of the bridge column formwork can effectively increase the strength, anti-slip properties, and load-bearing capacity of the steel formwork.

[0014] Preferably, the fixed connection structure includes a connector, a fixing screw, a fixing nut, and a circular through groove. The connector is fixedly installed at both ends of the side wall of the bridge column template. Circular through grooves are equally spaced on the side wall of the connector. The fixing screw is threaded into the circular through groove, and the fixing nut is threaded into both ends of the fixing screw.

[0015] In this technical solution, tightening the fixing nut can secure the two connectors together tightly, thereby firmly fixing the four bridge column formwork together to form a square column formwork.

[0016] Preferably, the side wall of the connector connected to the bridge column template is provided with a snap-fit ​​groove, the length of the snap-fit ​​groove is consistent with the length of the connector, and the side walls on both sides of the snap-fit ​​groove are provided with sliding grooves, the sliding grooves and the snap-fit ​​grooves are interconnected.

[0017] Preferably, a sealing plate is snapped into the snap-fit ​​groove.

[0018] In this technical solution, the sealing plate can effectively seal the joint between the two bridge column formworks, preventing grout leakage when the formwork joint is not tight enough.

[0019] Preferably, the clamping structure includes a fixing cap, a threaded rod, a connecting sleeve, a connecting block, and a clamping frame. The threaded rod is threadedly connected to the side wall of the connector. One end of the threaded rod is fixedly connected to the fixing cap, and the other end of the threaded rod extends into the sliding groove and is fixedly connected to the connecting block. The connecting block is rotatably connected to the connecting sleeve. An "L"-shaped clamping frame is fixedly connected to the side wall of the connecting sleeve. The end side wall of the clamping frame is inclined, and the clamping frame is slidably connected in the sliding groove.

[0020] In this technical solution, the fixing cap is turned, which causes the threaded rod to rotate. The threaded rod rotates and moves, which causes the connecting block to move. The connecting block pushes the clamping frame to move, so that the clamping frame extends out of the sliding groove and inserts into the side wall between the sealing plate and the snap-fit ​​groove.

[0021] Preferably, the fixing cap is configured as a hexagonal structure.

[0022] In this technical solution, it is convenient to use tools to twist the fixing cap.

[0023] Preferably, the sum of the thicknesses of the clamping frame and the sealing plate is consistent with the width of the locking groove.

[0024] In this technical solution, the sealing plate can be pushed tightly against the side wall of the bridge column formwork as the clamping frame is inserted.

[0025] Preferably, the support structure includes a support frame and support rods. The top side wall of the support frame is fixedly connected to the top side wall of the vertical rib of the template. The vertical rod of the support frame is inclined outward. Support rods are fixedly connected at equal intervals on the side wall of the support frame. The other end of the support rod is fixedly connected to the side wall of the bridge column template. The positions of the support rod and the horizontal rib of the template are staggered.

[0026] In this technical solution, the support frame is supported on the ground, expanding the support range at the bottom of the bridge column formwork, so that the bridge column formwork is stably supported on the ground. The support rod is supported on the side wall of the bridge column formwork, which makes good use of the support frame to support the side wall of the bridge column formwork, further ensuring the stability of the side wall of the bridge column formwork.

[0027] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0028] The positive and progressive effects of this utility model are as follows:

[0029] 1. By inserting the sealing plate into the snap-fit ​​groove between the two connectors, and turning the fixing cap, the fixing cap rotates, causing the threaded rod to rotate. The rotation of the threaded rod pushes the clamping frame to move, so that the clamping frame extends out of the sliding groove and inserts into the side wall between the sealing plate and the snap-fit ​​groove. As the clamping frame is inserted, the sealing plate is pushed tightly against the side wall of the bridge column formwork, sealing the joint between the two bridge column formworks. This facilitates better sealing of the joint of the bridge column formwork and avoids grout leakage due to insufficient tightness of the formwork joint.

[0030] 2. By supporting the bridge column formwork on the ground with a support frame, the support range at the bottom of the formwork is expanded, ensuring that the formwork is stably supported on the ground. The support rods support the side walls of the formwork, making better use of the support frame to support the side walls of the formwork, further ensuring the stability of the side walls of the formwork. This facilitates a more stable support for the entire bridge column formwork and prevents movement during concrete pouring, which could lead to problems in the column pouring process.

[0037] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0038] like Figure 1-4 As shown, the bridge column steel formwork includes bridge column formwork 1, and also includes:

[0039] Support structure 3 is installed on bridge column formwork 1;

[0040] Fixed connection structure 4 is provided at both ends of the bridge column template 1, and the connection structure provides a fixed connection between the bridge column templates 1.

[0041] A clamping structure 6 is provided on the connecting structure.

[0042] The bridge column template 1 has a "∟" shaped structure, and there are four bridge column templates 1. The four bridge column templates 1 are connected end to end to form a square structure.

[0043] This allows the assembled bridge column formwork to be used for casting square bridge columns.

[0044] The side wall of the bridge column template 1 is provided with a protruding template horizontal rib 2, which is equidistant from the vertical direction of the bridge column template 1. The side wall of the bridge column template 1 is provided with a protruding template vertical rib 5, which is perpendicular to the template horizontal rib 2.

[0045] The horizontal ribs 2 and vertical ribs 5 on the bridge column formwork 1 can effectively increase the strength, anti-slip properties, and load-bearing capacity of the steel formwork.

[0046] The fixed connection structure 4 includes a connector 401, a fixing screw 402, a fixing nut 403, and a circular through groove 404. The connector 401 is fixedly installed at both ends of the side wall of the bridge column template 1. Circular through grooves 404 are equally spaced on the side wall of the connector 401. The fixing screw 402 is threaded into the circular through groove 404. The fixing nuts 403 are threaded into both ends of the fixing screw 402.

[0047] Tightening the fixing nut 403 will make the two connectors 401 tightly fixed together, thereby making the four bridge column templates 1 firmly fixed together to form a square column template.

[0048] The connector 401 has a snap-fit ​​groove 411 on its side wall that connects to the bridge column template 1. The length of the snap-fit ​​groove 411 is the same as the length of the connector 401. Sliding grooves 412 are provided on the side walls on both sides of the snap-fit ​​groove 411. The sliding grooves 412 and the snap-fit ​​groove 411 are interconnected.

[0049] A sealing plate 7 is snapped into the slot 411.

[0050] The sealing plate 7 can effectively seal the joint between the two bridge column formwork 1, preventing grout leakage when the formwork joint is not tight enough.

[0051] The clamping structure 6 includes a fixing cap 601, a threaded rod 602, a connecting sleeve 603, a connecting block 604, and a clamping frame 605. The threaded rod 602 is threadedly connected to the side wall of the connector 401. One end of the threaded rod 602 is fixedly connected to the fixing cap 601, and the other end of the threaded rod 602 extends into the sliding groove 412 and is fixedly connected to the connecting block 604. The connecting sleeve 603 is rotatably connected to the connecting block 604. An "L"-shaped clamping frame 605 is fixedly connected to the side wall of the connecting sleeve 603. The end side wall of the clamping frame 605 is inclined, and the clamping frame 605 is slidably connected in the sliding groove 412.

[0052] Tighten the fixing cap 601. The rotation of the fixing cap 601 causes the threaded rod 602 to rotate. The rotation of the threaded rod 602 causes it to move. The movement of the threaded rod 602 causes the connecting block 604 to move. The connecting block 604 pushes the clamping frame 605 to move, so that the clamping frame 605 extends out of the sliding groove 412 and inserts into the side wall between the sealing plate 7 and the snap-fit ​​groove 411.

[0053] The fixing cap 601 is configured as a hexagonal structure.

[0054] The cap 601 can be easily turned with the aid of tools.

[0055] The sum of the thicknesses of the clamping frame 605 and the sealing plate 7 is consistent with the width of the snap-fit ​​groove 411.

[0056] With the insertion of the clamping frame 605, the sealing plate can be pushed tightly against the side wall of the bridge column template 1.

[0057] The support structure 3 includes a support frame 301 and a support rod 302. The top side wall of the support frame 301 is fixedly connected to the top side wall of the vertical rib of the template 5. The vertical rod of the support frame 301 is inclined outward. Support rods 302 are fixedly connected at equal intervals on the side wall of the support frame 301. The other end of the support rod 302 is fixedly connected to the side wall of the bridge column template 1. The positions of the support rod 302 and the horizontal rib of the template are staggered.

[0058] The support frame 301 is supported on the ground, expanding the support range at the bottom of the bridge column formwork 1, so that the bridge column formwork 1 is stably supported on the ground. The support rod 302 is supported on the side wall of the bridge column formwork 1, making good use of the support frame 301 to support the side wall of the bridge column formwork 1, further ensuring the stability of the side wall of the bridge column formwork 1.

[0059] In use, the bridge column template 1 is assembled by connecting the four bridge column templates 1 end to end. The fixing screw 402 is threaded into the circular through groove 404 on the two connecting parts 401 that are connected to each other. The fixing nut 403 is then threaded into both ends of the fixing screw 402 and tightened so that the four bridge column templates 1 are fixedly connected together end to end.

[0060] Next, insert the sealing plate 7 into the snap-fit ​​groove 411 between the two connectors 401, and then turn the fixing cap 601. The rotation of the fixing cap 601 drives the threaded rod 602 to rotate. The threaded rod 602 rotates and moves. The movement of the threaded rod 602 drives the connecting block 604 to move. The connecting block 604 pushes the clamping frame 605 to move, so that the clamping frame 605 extends out of the sliding groove 412 and inserts into the side wall between the sealing plate 7 and the snap-fit ​​groove 411. As the clamping frame 605 is inserted, the sealing plate is pushed tightly against the side wall of the bridge column formwork 1, sealing the joint of the two bridge column formwork 1. This facilitates better sealing of the joint of the bridge column formwork 1 and avoids grout leakage due to insufficient tightness of the formwork joint.

[0061] After the entire bridge column formwork 1 is assembled, it is hoisted and fitted onto the outside of the tied bridge column reinforcement. After being lowered, the support frame 301 supports it on the ground, expanding the support range at the bottom of the bridge column formwork 1, so that the bridge column formwork 1 is stably supported on the ground. The support rod 302 supports the side wall of the bridge column formwork 1, making good use of the support frame 301 to support the side wall of the bridge column formwork 1, further ensuring the stability of the side wall of the bridge column formwork 1, making it easier to make the entire bridge column formwork 1 more stable, and avoiding movement during the concrete pouring process, which could cause problems in the column pouring.

The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
