Bridge cap beam construction support

Abstract

This utility model discloses a bridge cap beam construction support, relating to the technical field of cap beam construction support. The utility model includes a steel pipe column, with a longitudinal beam installed on the top of the column. The longitudinal beam is H-shaped, and crossbeam plates are installed on the longitudinal beam in a cross-shaped arrangement. A first groove is formed at the middle of both ends of the lower surface of the crossbeam plate. A symmetrically arranged movable plate is located at both ends of the first groove on the lower surface of the crossbeam plate. A corresponding positioning block is fixed to the side of the movable plate facing the longitudinal beam. For a large number of crossbeam plates, traditional installation requires aligning and fixing them one by one, a cumbersome and time-consuming process. This structure, however, uses a movable plate inserted into the longitudinal beam and a rotating wheel to drive a slider to engage the positioning block in the longitudinal beam. This allows for rapid initial positioning of the crossbeam plate and the longitudinal beam, eliminating the need for repeated precise alignment. This allows workers to quickly lay multiple crossbeam plates sequentially on the longitudinal beam, significantly shortening the installation time for a large number of crossbeam plates.

Description

Technical Field

[0001] This utility model relates to the field of bridge cap beam construction support technology, specifically a bridge cap beam construction support. Background Technology

[0002] A cap beam is a horizontal beam installed on top of a pier in a bridge structure to support, distribute, and transfer the load of the superstructure. Its main function is to support the superstructure and transfer all loads to the substructure. During the construction of bridge cap beams, temporary supports are required, and a working area must be provided for construction workers. Figure 4 As shown, when initially setting up the support for bridge cap beam construction, two longitudinal beams symmetrically positioned around the column pier are erected on top of the steel pipe columns. Subsequently, multiple equally spaced transverse beams are installed on top of these beams, and the remaining work area is then built on the foundation of the transverse beams. However, when installing the transverse beams, they are currently fixed to the longitudinal beams using corresponding fixing bolts. In this process, the transverse beams must first be aligned, and then each transverse beam is installed one by one. For a large number of transverse beams, this process is slow and the operation steps are quite complicated. Utility Model Content

[0003] In order to solve the above problems, the purpose of this utility model is to provide a bridge cap beam construction support.

[0004] To solve the above technical problems, the present invention adopts the following technical solution: a bridge cap beam construction support, including a steel pipe column, a longitudinal beam installed on the top of the steel pipe column, the longitudinal beam being distributed in an H-shape, a cross beam plate installed on the longitudinal beam, a first sliding groove being formed at the middle of both ends of the lower surface of the cross beam plate, a symmetrically arranged movable plate being provided at both ends of the lower surface of the cross beam plate at the first sliding groove, a positioning block being fixedly provided on the side of the movable plate facing the longitudinal beam, a screw rod with opposite threads at both ends being rotatably installed in the first sliding groove, a slider being slidably installed at both ends of the first sliding groove, and the bottom of the slider being fixedly installed on the corresponding movable plate, the two sliders located in the first sliding groove being threaded into the two ends of the screw rod respectively.

[0005] Preferably, one end of the lead screw near the end of the crossbeam plate passes through the crossbeam plate and is fixedly equipped with a wheel.

[0006] Preferably, the lower surfaces at both ends of the crossbeam plate are provided with second grooves on both sides of the first groove, and movable blocks are slidably provided in the second grooves. The bottom of the movable blocks is fixedly mounted on the adjacent movable plates. A support rod is fixedly provided in the second groove, and the movable blocks located in the second groove are movably inserted into the support rod.

[0007] Preferably, the bottom of the movable plate is fixedly provided with a horizontally arranged stop block, which can be inserted into the lower part of the longitudinal beam along with the movable plate. The bottom of the stop block is threaded with a fixing bolt, and the bottom of the positioning block is provided with a threaded groove corresponding to the fixing bolt.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] For a large number of crossbeams, traditional installation requires aligning each one individually before fixing them, which is cumbersome and time-consuming. This structure, however, uses a moving plate inserted into the longitudinal beam and a rotating wheel to drive the slider to engage the positioning block in the longitudinal beam. This allows for quick initial positioning of the crossbeams and longitudinal beams, eliminating the need for repeated precise alignment. This enables workers to quickly lay multiple crossbeams on the longitudinal beams in sequence, significantly reducing the installation time for a large number of crossbeams.

[0016] 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.

[0017] Example: Figure 1-4 As shown, this utility model provides a bridge cap beam construction support, including a steel pipe column 1. A longitudinal beam 11 is installed on the top of the steel pipe column 1. The longitudinal beam 11 is H-shaped. A crossbeam plate 12 is installed on the longitudinal beam 11 in a cross-shaped arrangement. A first sliding groove 13 is opened at the middle of both ends of the lower surface of the crossbeam plate 12. A symmetrically arranged movable plate 15 is provided on the lower surface of the crossbeam plate 12 at both ends of the first sliding groove 13. A positioning block 16 is fixedly provided on the side of the movable plate 15 facing the longitudinal beam 11. A screw rod 18 with opposite threads at both ends is rotatably installed in the first sliding groove 13. A slider 14 is slidably installed at both ends of the first sliding groove 13, and the bottom of the slider 14 is fixedly installed on the corresponding movable plate 15. The two sliders 14 located in the first sliding groove 13 are respectively threaded into the two ends of the screw rod 18.

[0018] One end of the lead screw 18 near the end of the crossbeam plate 12 passes through the crossbeam plate 12 and is fixedly equipped with a rotating wheel 19. The rotating wheel 19 can help the operator to quickly drive the lead screw 18 to rotate, improving the convenience of operation.

[0019] The lower surfaces of both ends of the crossbeam plate 12 are provided with second slide grooves 2 on both sides of the first slide groove 13. Movable blocks 21 are slidably provided in the second slide grooves 2. The bottom of the movable blocks 21 is fixedly set on the adjacent movable plate 15. The movable blocks 21 are set at both ends of the movable plate 15 so that when the subsequent slider 14 drives the movable plate 15 to move, it can be stably translated and deviated.

[0020] A support rod 22 is fixedly installed in the second slide groove 2. The movable block 21 located in the second slide groove 2 is movably inserted on the support rod 22. The support rod 22 helps to stably drive the movable block 21 to move the moving plate 15 horizontally.

[0021] The bottom of the movable plate 15 is fixedly provided with a horizontally arranged stop block 3. The stop block 3 can be inserted into the lower part of the longitudinal beam 11 along with the movable plate. The bottom of the stop block 3 is threaded with a fixing bolt 31. The bottom of the positioning block 16 is provided with a threaded groove corresponding to the fixing bolt 31. By inserting the fixing bolt 31 into the positioning block 16, the final fixed connection between the crossbeam plate 12 and the longitudinal beam 11 can be completed.

[0022] Working principle: During use, when installing the crossbeam plate 12 above the longitudinal beam 11, the operator can directly place the crossbeam plate 12 on two adjacent longitudinal beams 11. The two symmetrically arranged movable plates 15 at both ends of the crossbeam plate 12 will be inserted into the longitudinal beam 11. Then, the operator can directly rotate the rotating wheels 19 at both ends, which can directly drive the lead screw 18 to rotate. Since the threads at both ends of the lead screw 18 are opposite, the sliders 14 at both ends of the lead screw 18 will move towards each other simultaneously. At this time, the sliders 14 will drive the movable plates 15 fixed at the bottom to move towards the longitudinal beam 11. At this time, the movable plates 15 on both sides of the adjacent longitudinal beam 11 will move towards each other simultaneously, causing the positioning blocks 16 to be engaged into the longitudinal beam 11. At this time, the crossbeam plate 12 and the longitudinal beam 11 will quickly move towards each other. After the positioning is completed, the subsequent workers can mainly place multiple crossbeam plates 12 on the longitudinal beams 11 in sequence. After the installation is completed, the subsequent workers can insert the fixing bolts 31 into the threaded grooves in the positioning block 16 through the stop block 3 at the bottom of the moving plate 15. During this process, the fixing bolts 31 can be used to make the moving plate 15, the positioning block 16 and the crossbeam plates 12 finally fixed and installed through the stop plate. Through the above operation, the initial positioning operation between the crossbeam plates 12 and the longitudinal beams 11 can be completed quickly. For a large number of crossbeam plates 12 that need to be installed, the above operation can greatly reduce the operation and installation steps, and at the same time, the crossbeam plates 12 can be quickly laid on the longitudinal beams 11, which helps the workers to quickly complete the construction operation on the bracket.
