Description

Technical Field

[0001] This utility model relates to the field of bridge engineering construction technology, and in particular to a side formwork support device for an extra-large No. 0 block of a bridge. Background Technology

[0002] During the segmental construction of the main girder of the bridge, each segment is called a "block". Among them, block 0, as the first block to be poured in the main girder, is located at the pier and is the starting point for the subsequent segmental construction of the main girder. Therefore, its construction is one of the key links in the segmental construction of the main girder of the bridge.

[0003] As the scale of bridges increases, especially for the No. 0 block of ultra-large bridges, the construction difficulty also increases significantly. One key issue is that the huge amount of concrete poured will exert a significant squeezing effect on the side formwork of the No. 0 block, which can easily lead to deformation of the side formwork and even the risk of it being crushed by the concrete.

[0004] To address this issue, existing methods for limiting the side formwork of block 0 mainly involve tensioning steel wire ropes or steel bundles on the inner side of the corresponding side formwork. However, this method is cumbersome to implement and only provides effective limiting for localized positions of the tensioning ropes on the side formwork.

[0005] For extra-large No. 0 blocks, the larger volume of concrete poured results in more severe compression of the side formwork, making displacement issues more prominent. Therefore, the conventional method of tensioning ropes inside the side formwork is insufficient to effectively address the limitation problem of the side formwork for extra-large No. 0 blocks. Utility Model Content

[0006] To address the aforementioned issues, this utility model aims to propose a side template support device for an extra-large No. 0 block of a bridge. It uses an L-shaped support mechanism in conjunction with an adjustment mechanism for adaptive adjustment. When the adjustment is in place, the side template of the No. 0 block is fixed by anchoring the L-shaped support mechanism.

[0007] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0008] A support device for the side formwork of a large bridge block 0 includes at least one L-shaped support mechanism and an adjustment mechanism. The long end of the L-shaped support mechanism is installed on the side formwork of the block 0 through the adjustment mechanism. When the position of the L-shaped support mechanism is adjusted to the correct position through the adjustment mechanism, the L-shaped support mechanism is anchored to the ground to form a limiting support for the side formwork of the block 0.

[0009] Furthermore, the L-shaped support mechanism is composed of several square components, which are formed by welding several perforated angle steels. The square components have several vertical and horizontal reserved holes. The several square components are spliced ​​together to form the L-shaped support mechanism by installing tapered bolts through the vertical reserved holes and tie bolts through the horizontal reserved holes.

[0010] Furthermore, one end of the tapered bolt and both ends of the tie bolt are fixed and limited by washers and bolt caps.

[0011] Furthermore, the adjustment mechanism includes an H-beam, a slide groove, and a slider. The slide groove is fixed to the L-shaped support mechanism by the tie bolts. The slider is installed in the slide groove, and the distance is adjusted by the slider. One side of the H-beam is assembled with the slider, and the other side is fixed to the side template of block 0 with bolts.

[0012] Furthermore, one side of the H-beam is fixed to the side mold by bolts.

[0013] Furthermore, the slide is placed vertically on one side of the long end of the L-shaped support mechanism and fixed by tie bolts. The slider includes a horizontal bayonet and a vertical bayonet. The horizontal bayonet is matched with the other side of the H-beam and the vertical bayonet is matched with the slide.

[0014] Beneficial Effects: This invention allows for adjustment of the L-shaped support mechanism's position on the side formwork of block 0 via an adjustment mechanism. Once adjusted to the correct position, anchoring can be performed. When concrete is poured into the block formwork, this device effectively resists the compressive force of the concrete on the side formwork of the main beam, ensuring the safety of the side formwork. This device is simple in structure, easy to operate, effective, low in cost, and highly safe, and has broad application prospects in pouring concrete for bridge main beams.

[0020] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] Example 1

[0022] See Figure 1-4 A support device for the side template of a large bridge block 0 includes at least one L-shaped support mechanism and an adjustment mechanism. The long end of the L-shaped support mechanism is installed on the side template 4 of the block 0 through the adjustment mechanism. When the position of the L-shaped support mechanism is adjusted to the correct position through the adjustment mechanism, the L-shaped support mechanism is anchored to the ground to form a limiting support for the side template 4 of the block 0.

[0023] This embodiment allows for adjustment of the L-shaped support mechanism's position on the side formwork of block 0 via an adjustment mechanism. Once adjusted to the correct position, anchoring can be performed. When concrete is poured into the formwork of block 0, this device effectively resists the compressive force of the concrete on the side formwork of the main beam, ensuring the safety of the side formwork. This device is simple in structure, easy to operate, effective, low in cost, and highly safe, and has broad application prospects in pouring concrete for bridge main beams.

[0024] In a specific example, the L-shaped support mechanism is composed of several square components 1 spliced ​​together. The square components 1 are several perforated angle steels welded together. The square components 1 are provided with several vertical reserved holes and horizontal reserved holes. The several square components 1 are spliced ​​together to form the L-shaped support mechanism by installing tapered bolts 8 through the vertical reserved holes and tie bolts 9 through the horizontal reserved holes.

[0025] The L-shaped support mechanism of this embodiment is formed by welding and splicing several perforated angle steels with tapered bolts and tie bolts. The splicing cost is low and the structural strength is high. The tapered bolts of this embodiment can pass through the vertical reserved holes of the cube component in the vertical direction and finally be anchored in the ground, thereby realizing the final support and fixation limit of the L-shaped support mechanism.

[0026] In a specific example, one end of the tapered bolt 8 and both ends of the tie bolt 9 are fixed and limited by the washer 3 and the bolt cap 2.

[0027] This embodiment improves the stability of the fixed installation of tapered bolts and tie bolts by using shims and bolt caps.

[0028] In a specific example, the adjustment mechanism includes an H-beam 5, a slide 7, and a slider 6. The slide 7 is fixed to the L-shaped support mechanism by the tie bolts 9. The slider 6 is installed in the slide 7 and the distance is adjusted by the slider 6. One side of the H-beam 5 is assembled with the slider 6, and the other side is fixed to the side template 4 of block 0 with bolts.

[0029] In this embodiment, the distance adjustment of the L-shaped support mechanism is achieved through the cooperation of the slider and the groove.

[0030] In a specific example, one side of the H-beam 5 is fixed to the side mold 4 by bolts.

[0031] In a specific example, the slide 7 is placed vertically on one side of the long end of the L-shaped support mechanism and fixed by the tie bolt 9. The slider 6 includes a horizontal bayonet and a vertical bayonet. The horizontal bayonet is matched with the other side of the H-beam 5 and the vertical bayonet is matched with the slide 7.

[0032] This embodiment enables the horizontal displacement adjustment and vertical position adjustment of the L-shaped support mechanism through the horizontal and vertical locking slots of the slider, thereby improving the adaptability of the L-shaped support mechanism.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
