[0001] This utility model relates to the field of bridge precast slab support technology, and in particular to a bridge precast slab support device for bridge construction. Background Technology

[0002] A support device is a specialized device used during bridge construction to support and secure precast slabs. Its core function is to provide stable support for the precast slabs during transportation, installation, and construction, ensuring construction safety and quality.

[0003] However, in existing technologies, some bridge precast slab support devices have fixed structures, making it difficult to flexibly adjust the support height and angle according to precast slabs of different specifications and shapes, resulting in poor applicability of the devices. Some support devices also lack support stability, and are prone to swaying and deformation when subjected to the weight of the precast slabs and external forces during construction, affecting the quality and safety of bridge construction. In addition, some support devices are complicated to operate, inconvenient to assemble and disassemble, increasing the workload of construction personnel, reducing construction efficiency, and having high maintenance costs. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of fixed structure, inconvenient adjustment, difficulty in adapting to different specifications of precast slabs, poor support stability, easy shaking and deformation during construction, and complicated operation of the existing support device. Therefore, a bridge precast slab support device for bridge construction is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a bridge precast slab support device for bridge construction, comprising a base, a support mechanism fixedly connected to the top of the base, the support mechanism comprising a base plate, a first bonding plate and a second bonding plate, fixing blocks fixed to the upper surface of the base plate and the lower surface of the first bonding plate, a first support rod rotatably connected to both ends of the fixing block, a second support rod rotatably connected to the other end of the first support rod, the other end of the second support rod rotatably connected to the inner side of the fixing block on the lower surface of the first bonding plate, connecting pieces fixedly installed on both sides of the first bonding plate, one end of the second bonding plate rotatably connected to the connecting piece, and the second bonding plate and the first bonding plate being located on the same horizontal plane.

[0006] Preferably, a recess is provided at the junction of the second bonding plate and the connecting piece.

[0008] Preferably, a side rod is rotatably connected to the inner side of the connector.

[0009] Preferably, the angle between the vertical plane of the side rod and the vertical plane of the first support rod is ninety degrees.

[0010] Preferably, a sleeve is rotatably connected to the lower surface of the second bonding plate, and the sleeve is slidably connected to the side rod.

[0011] Preferably, a handle is fixedly installed on the outer wall of the sleeve.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the support area is adjusted by rotating the second bonding plate to adapt to precast slabs of different shapes, thereby achieving support for bridge precast slabs. The support mechanism is adjustable and can flexibly adjust the support height and angle according to construction needs, enhancing the applicability of the device, expanding the support area, and better supporting bridge precast slabs of different specifications. This improves the stability and reliability of the support, effectively ensuring the safety and stability of bridge precast slabs during the support process, and improving the efficiency and quality of bridge construction.

[0022] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a bridge precast slab support device for bridge construction, including a base 1. A support mechanism 2 is fixedly connected to the top of the base 1. The support mechanism 2 includes a base plate 21, a first bonding plate 22, and a second bonding plate 29. Fixing blocks 23 are fixed on the upper surface of the base plate 21 and the lower surface of the first bonding plate 22. A first support rod 24 is rotatably connected to both ends of the fixing block 23. A second support rod 25 is rotatably connected to the other end of the first support rod 24. The other end of the second support rod 25 is rotatably connected to the inner side of the fixing block 23 on the lower surface of the first bonding plate 22. Connecting pieces 211 are fixedly installed on both sides of the first bonding plate 22. One end of the second bonding plate 29 is rotatably connected to the connecting piece 211. The second bonding plate 29 and the first bonding plate 22 are located on the same horizontal plane.

[0023] The specific setup and function of this embodiment are described below. A support mechanism 2 is fixed to the top of the base 1. The base 1 is used to connect with other lifting mechanisms and is positioned below the precast bridge slab. The first bonding plate 22 and the second bonding plate 29 in the support mechanism 2 are bonded to the lower surface of the precast bridge slab. Fixing blocks 23 are fixed to the bottom plate 21 and the lower surface of the first bonding plate 22 in the support mechanism 2. The two ends of the fixing blocks 23 are rotatably connected to the first support rod 24, and the other end of the first support rod 24 is rotatably connected to the second support rod 25. The other end of the second support rod 25 is rotatably connected to the inner side of the fixing block 23 on the lower surface of the first bonding plate 22. The rotatable support structure is formed by the rotatable connection of the first support rod 24 and the second support rod 25. This structure can be flexibly adjusted when the support height or angle needs to be adjusted. Connecting pieces 211 are fixed to both sides of the first bonding plate 22. One end of the second bonding plate 29 is rotatably connected to the connecting piece 211 and is located on the same horizontal plane as the first bonding plate 22. The support area can be adjusted by rotating the second bonding plate 29 to adapt to precast slabs of different shapes, thereby supporting the bridge precast slabs. The rotatable connection design of the first support rod 24 and the second support rod 25 makes the support mechanism 2 adjustable, which can flexibly adjust the support height and angle according to construction needs, enhancing the applicability of the device. The first bonding plate 22 and the second bonding plate 29 are rotatably connected by the connecting piece 211, which can expand the support area and better support bridge precast slabs of different specifications, improving the stability and reliability of the support. The components are tightly connected and flexible, which is convenient for installation and use in bridge construction, effectively ensuring the safety and stability of the bridge precast slab support process and improving the efficiency and quality of bridge construction.

[0024] Example 2: Figure 1 and Figure 2 As shown, a recessed portion 210 is provided at the junction of the second bonding plate 29 and the connecting piece 211. A connecting head 212 is rotatably mounted on the upper surface of the base plate 21. A side rod 26 is rotatably connected to the inner side of the connecting head 212. The angle between the vertical plane of the side rod 26 and the vertical plane where the first support rod 24 is located is ninety degrees. A sleeve 27 is rotatably connected to the lower surface of the second bonding plate 29. The sleeve 27 is slidably connected to the side rod 26. A handle 28 is fixedly installed on the outer wall of the sleeve 27.

[0025] The overall effect of this embodiment is that the recess 210 at the junction of the second bonding plate 29 and the connecting piece 211 can be used for positioning or accommodating components; the connecting head 212 on the base plate 21 is rotatable, allowing adjustment of the angle between the side rod 26 and the first support rod 24, thereby adapting to changes in the angle of the second bonding plate 29; the side rod 26 provides the most stable support when it forms a 90-degree angle with the vertical plane of the first support rod 24, ensuring overall structural stability; the sleeve 27, rotatably connected to the lower surface of the second bonding plate 29, is slidably connected to the side rod 26, ensuring stable support for the second bonding plate 29. The handle 28 facilitates the handling of the device by construction personnel and reduces the difficulty of assembly. The recessed part 210 enhances the structural stability or positioning accuracy at the junction. The rotating and sliding connection design of the connector 212, side rod 26, and sleeve 27 allows the device to achieve flexible multi-angle adjustment. The handle 28 facilitates manual operation and improves the ease of use. It achieves the technical effect of flexible operation, convenient adjustment, and stable structure. The recessed part 210 optimizes the connection structure between the second bonding plate 29 and the connecting piece 211, ensuring that the two form a stable and flexible joint point at the junction.

[0026] The usage and working principle of this device are as follows: When using this bridge precast slab support device for bridge construction, first place the base 1 on a flat and stable construction ground. According to the specifications of the bridge precast slab and the support requirements, rotate the first support rod 24 and the second support rod 25 at both ends of the fixing block 23 on the lower surface of the base plate 21 and the first bonding plate 22 to adjust the support height and angle, forming a stable support structure. If it is necessary to expand the support area or adapt to precast slabs of different shapes, rotate the second bonding plate 29 to rotate it around the connecting piece 211 to a suitable position. During this process, the connecting head 212 will rotate synchronously to adjust the angle between the side rod 26 and the first support rod 24, so that the side rod 26 is in a stable support state with a 90-degree angle to the vertical plane where the first support rod 24 is located. Then, by sliding the sleeve 27 through the handle 28, the second bonding plate 29 is driven to rotate around its connection with the connecting piece 211 to adjust to a suitable angle. The recessed part 210 is used to achieve precise positioning and stable connection, completing the support operation for the bridge precast slab.
