Abstract
Description
Technical Field
[0001] This utility model relates to the field of bridge construction technology, specifically to a simple temporary formwork support. Background Technology
[0002] During bridge construction, when constructing large concrete structures such as box girders and abutments in open areas, due to the limitations of the construction site, sand buckets are typically installed on top of the piers after the pier construction is completed as temporary supports to support the formwork of large concrete structures such as box girders and abutments. These temporary sand bucket supports are used to support the formwork for pouring. When other construction procedures are completed and the box girders and abutments need to be lowered onto permanent bridge supports, fine sand is released from the sand buckets through openings on the side, lowering pistons or pads on the sand and allowing the box girders and abutments to fall. However, using sand buckets as temporary supports makes it difficult to control the formwork elevation and flatness, and adjusting the amount of sand in the buckets is cumbersome, easily leading to waste of construction costs, including labor and time. Therefore, a temporary support system that allows for easy adjustment of the formwork elevation of large concrete structures such as box girders and abutments during open-air construction is needed to increase construction efficiency. Utility Model Content
[0003] One of the objectives of this utility model is to provide a simple temporary formwork support to solve the problem that the formwork elevation of large concrete structures under construction in open terrain is not simple and quick enough in the existing technology.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A simple temporary formwork support for installation on the top of a bridge pier and supporting bridge formwork includes: a lower support member, an upper support member, and multiple adjusting components. The lower support member is installed on the top of the bridge pier. The upper support member is located on the side of the lower support member away from the top of the bridge pier and is used to support the bridge formwork. The adjusting components connect the lower support member and the upper support member and are configured to allow the upper support member to move away from or closer to the lower support member to adjust the top elevation of the upper support member. A limiting component is located between the lower support member and the upper support member and abuts against the lower support member and the upper support member respectively to lock the relative positions of the lower support member and the upper support member, so that the lower support member and the upper support member can be stably supported between the top of the bridge pier and the bridge formwork.
[0006] Based on the aforementioned technical means, the adjustment component can repeatedly adjust the upper support to move away from or closer to the lower support, precisely adjusting the top elevation of the upper support to adapt to support scenarios with different height and spacing requirements. It has a fast and convenient effect, which not only improves the accuracy of the bridge formwork support position, but also improves the construction efficiency of large concrete structures. The limiting component can lock the relative distance between the upper and lower support, improving the stability of the temporary support.
[0007] Furthermore, each of the adjustment components includes a support rod, a lower fixing member, and an upper fixing member. The lower fixing member is installed on the lower support member, and the upper fixing member is installed on the upper support member. One end of the support rod passes through the lower fixing member and abuts against the top of the bridge pier, while the other end is movably installed on the upper fixing member.
[0008] According to the above technical means, by connecting the lower support and the upper support through the support rod, the lower fixing part and the upper fixing part, the stability of the lower support and the upper support can be ensured during the adjustment process; the other end of the support rod is movably installed on the upper fixing part, which can provide a limit for the movement of the upper support and prevent the upper support from deviating during the movement.
[0009] Furthermore, each of the adjustment components also includes a positioning nut and a first locking nut. The support rod has threads, and both the positioning nut and the first locking nut are threadedly connected to the support rod. The positioning nut is located below the upper fixing member and is used to adjust the position of the upper fixing member on the support rod. The first locking nut is located above the upper fixing member and is used to lock the upper fixing member.
[0010] According to the above technical means, the positioning nut can adjust the position of the upper fixing member on the support rod, and then the first locking nut is used to lock the upper fixing member, further fixing the position of the upper support member and increasing the support reliability of the upper support member.
[0011] Furthermore, a first limiting hole is formed on the lower fixing member, and a second limiting hole is formed on the upper fixing member, with both ends of the support rod passing through the first limiting hole and the second limiting hole, respectively.
[0012] Based on the above technical means, the first limiting hole and the second limiting hole can restrict the installation position of the support rod, thereby improving the accuracy of the support rod installation position.
[0013] Furthermore, a support plate is formed at one end of the support rod that abuts against the top of the bridge pier to increase the contact area between the support rod and the top of the bridge pier.
[0014] Based on the above-mentioned technical means, the support plate can reduce the local pressure of the support rod on the top of the bridge pier and increase the stability of the support rod supporting the top of the bridge pier.
[0015] Furthermore, the adjustment components are provided in four groups and are symmetrically distributed on the outside of the lower support and the upper support.
[0016] Based on the above-mentioned technical means, the four sets of symmetrically distributed adjustment components can work together to prevent the temporary support from tilting or swaying due to uneven force distribution, thereby enhancing the structural stability of the temporary support.
[0017] Furthermore, the limiting component includes a locking member and two limiting blocks, the two limiting blocks being symmetrically arranged between the lower support member and the upper support member, and the opposite sides of each limiting block respectively abutting against the lower support member and the upper support member; the locking member is used to connect the two limiting blocks and is configured to allow the two limiting blocks to move closer or further apart from each other, so that the two limiting blocks abut against or release from abutting against the lower support member and the upper support member.
[0018] According to the above technical means, the locking component is used to bring the two limiting blocks closer together to tightly hold the lower support and the upper support, further locking the distance between the lower support and the upper support, while also providing support force for the upper support, strengthening the structural strength of the temporary support, and giving the temporary support support stability.
[0019] Furthermore, the locking component includes a locking screw and at least two second locking nuts. The two ends of the locking screw pass through the two limiting blocks respectively and are threadedly connected to the second locking nuts, so that when the locking nuts are screwed onto the locking screw, the two limiting blocks can be brought closer to each other.
[0020] Based on the above technical means, during construction, the two limit blocks can be brought closer to each other simply by turning the second locking nut on the locking screw. The operation is simple and convenient, and precise adjustment can be achieved, which improves construction efficiency.
[0021] Furthermore, the two sides of each of the limiting blocks that abut against the lower support and the upper support are not parallel, so that when the second locking nut pushes the two limiting blocks closer to each other, the lower support and the upper support can move away from each other.
[0022] According to the above technical means, when the two limiting blocks approach each other, a component force perpendicular to the moving direction of the limiting blocks can be generated, which acts on the lower support and the upper support respectively, further enabling the lower support and the upper support to move away from each other.
[0023] Furthermore, each of the limiting blocks has a through hole, and the two ends of the locking screw pass through the through holes of the two limiting blocks respectively and are threadedly connected to the second locking nut.
[0024] According to the above technical means, the locking screw passes through the through hole on the limiting block, which can easily connect the two limiting blocks. The through hole provides a positioning function for the installation of the locking screw, making the installation of the locking screw simple and quick and reducing the assembly difficulty.
[0025] The beneficial effects of this utility model are as follows:
[0026] The adjustment component can repeatedly adjust the upper support to move away from or closer to the lower support, precisely adjusting the top elevation of the upper support to adapt to support scenarios with different height and spacing requirements. It has a quick and easy effect, which not only improves the accuracy of the bridge formwork support position, but also improves the construction efficiency of large concrete structures. The limiting component can lock the relative distance between the upper and lower support, improving the stability of the temporary support. Attached Figure Description

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation.

For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium.

[0037] Example 1
[0038] This embodiment provides, as follows: Figures 1 to 3A simple temporary formwork support is shown for installation on the top of a bridge pier and to support bridge formwork. It includes: a lower support 100, an upper support 200, and multiple adjusting components. The lower support 100 is installed on the top of the bridge pier. The upper support 200 is located on the side of the lower support 100 away from the top of the bridge pier and is used to support the bridge formwork. The adjusting components connect the lower support 100 and the upper support 200 and are configured to allow the upper support 200 to move away from or closer to the lower support 100 to adjust the top elevation of the upper support 200. A limiting component 400 is located between the lower support 100 and the upper support 200 and abuts against both components to lock their relative positions, ensuring stable support between the bridge pier top and the bridge formwork.
[0039] When temporary supports are needed for concrete structures such as box girders and abutments that require construction in open areas during bridge construction, the temporary supports of this embodiment are pre-assembled and placed in pre-defined support positions. Then, the upper support member 200 is adjusted using the adjustment component to ensure its top reaches a preset support height and level. Finally, the limiting component 400 is adjusted to fix the distance between the lower support member 100 and the upper support member 200. After the temporary supports are adjusted, the bridge formwork is fixed to the upper support member 200, allowing for subsequent pouring construction. After the box girder and abutment construction is completed and the bridge formwork is removed, the temporary supports can be removed by reverse adjustment of the limiting component 400 and the adjustment component. Compared to sand bucket supports, this method is simpler and faster, and allows for precise control of the top elevation of the upper support member 200. It eliminates the need for additional construction materials such as fine sand, thus improving convenience.
[0040] The adjustment component can repeatedly adjust the upper support 200 to move away from or closer to the lower support 100, precisely adjusting the top elevation of the upper support 200 to adapt to support scenarios with different height and spacing requirements. It has a quick and convenient effect, which not only improves the accuracy of the bridge formwork support position, but also improves the construction efficiency of large concrete structures. The limiting component 400 can lock the relative distance between the upper support 200 and the lower support 100, improving the stability of the temporary support. Moreover, the temporary support in this embodiment can be reused, which is economical.
[0041] like Figure 1As shown, in this embodiment, each adjustment component includes a support rod 310, a lower fixing member 320, and an upper fixing member 330. The lower fixing member 320 is mounted on the lower support member 100, and the upper fixing member 330 is mounted on the upper support member 200. One end of the support rod 310 passes through the lower fixing member 320 and abuts against the top of the bridge pier, while the other end is movably mounted on the upper fixing member 330. Connecting the lower support member 100 and the upper support member 200 through the support rod 310, the lower fixing member 320, and the upper fixing member 330 ensures the stability of the lower support member 100 and the upper support member 200 during the adjustment process. The movable mounting of the other end of the support rod 310 on the upper fixing member 330 provides a limit for the movement of the upper support member 200, preventing the upper support member 200 from shifting during movement.
[0042] In this embodiment, both the lower fixing member 320 and the upper fixing member 330 are fixed steel plates, and are fixed to the lower support member 100 and the upper support member 200 respectively by welding.
[0043] like Figure 1 As shown, in this embodiment, each adjusting component further includes a positioning nut 340 and a first locking nut 350. The support rod 310 has threads, and both the positioning nut 340 and the first locking nut 350 are threadedly connected to the support rod 310. The positioning nut 340 is located below the upper fixing member 330 and is used to adjust the position of the upper fixing member 330 on the support rod 310. The first locking nut 350 is located above the upper fixing member 330 and is used to lock the upper fixing member 330. The positioning nut 340 can adjust the position of the upper fixing member 330 on the support rod 310, and then the first locking nut 350 is used to lock the upper fixing member 330, further fixing the position of the upper support member 200 and increasing the support reliability of the upper support member 200.
[0044] When temporary support is needed for concrete structures such as box girders and abutments that require construction in open spaces, use a wrench or other tools to tighten the positioning nut 340 to move the upper support 200 upwards and adjust the top elevation and level of the upper support 200 to the predetermined elevation (the level of the upper support 200 is adjusted here because the entire bridge beam is not level during bridge construction; therefore, to meet design requirements, the level of the upper support 200 needs to be adjusted so that it can fit the bridge formwork for support to the greatest extent). Then, tighten the first locking nut 350 to limit the upper fixing part 330 on the upper support 200 to the support rod 310, preventing the upper support 200 from shifting position when the limiting component 400 is adjusted later. Finally, use the limiting component 400 to limit the distance between the lower support 100 and the upper support 200.
[0045] like Figure 2As shown, in this embodiment, a first limiting hole is formed on the lower fixing member 320, and a second limiting hole 331 is formed on the upper fixing member 330. The two ends of the support rod 310 pass through the first limiting hole and the second limiting hole 331, respectively. The first limiting hole and the second limiting hole 331 can restrict the installation position of the support rod 310, thereby improving the accuracy of the installation position of the support rod 310.
[0046] like Figure 1 As shown, in this embodiment, a support plate 311 is formed at one end of the support rod 310 that abuts against the top of the bridge pier to increase the contact area between the support rod 310 and the top of the bridge pier. The support plate 311 can reduce the local pressure of the support rod 310 on the top of the bridge pier and increase the stability of the support rod 310 supporting the top of the bridge pier. In order to adapt to uneven bridge pier tops, one end of the support rod 310 that abuts against the top of the bridge pier can movably pass through the lower fixing member 320, and the end is not fixed to the lower support member 100. When the bridge pier top is uneven, the end of the support rod 310 that abuts against the top of the bridge pier can be on a different plane from the bottom of the lower support member 100.
[0047] Of course, in order to make the support rod 310 and the lower support member 100 have better integrity, in other embodiments, the support plate 311 on the support rod 310 can be fixed on the lower support member 100, and the support rod 310 can also be fixed to the lower fixing member 320 at the same time to strengthen the structural strength between the support rod 310 and the lower support member 100 and make it have integrity.
[0048] like Figure 2 As shown, in this embodiment, four sets of adjustment components are provided, symmetrically distributed on the outer sides of the lower support 100 and the upper support 200. The four symmetrically distributed sets of adjustment components can work together to prevent the temporary support from tilting or swaying due to uneven force distribution, thereby enhancing the structural stability of the temporary support.
[0049] To make the temporary support more stable, four or more sets of adjustment components can be installed.
[0050] like Figure 1As shown, in this embodiment, the limiting component 400 includes a locking member 410 and two limiting blocks 420. The two limiting blocks 420 are symmetrically arranged between the lower support member 100 and the upper support member 200, and the opposite sides of each limiting block 420 abut against the lower support member 100 and the upper support member 200 respectively. The locking member 410 is used to connect the two limiting blocks 420 and is configured to allow the two limiting blocks 420 to move closer or further apart, so that the two limiting blocks 420 abut against or release the abutment against the lower support member 100 and the upper support member 200. The locking member 410 is used to bring the two limiting blocks 420 closer together to tightly abut against the lower support member 100 and the upper support member 200, further locking the distance between the lower support member 100 and the upper support member 200, and at the same time providing support force for the upper support member 200, strengthening the structural strength of the temporary support, and giving the temporary support support stability.
[0051] like Figure 1 As shown, in this embodiment, the locking component 410 includes a locking screw 411 and at least two second locking nuts 412. The locking screw 411 passes through two limiting blocks 420 at both ends and is threadedly connected to the second locking nuts 412, so that when the locking nuts are screwed onto the locking screw 411, the two limiting blocks 420 can be brought closer together. During construction, the two limiting blocks 420 can be brought closer together simply by screwing the second locking nuts 412 onto the locking screw 411. The operation is simple and convenient, and precise adjustment can be achieved, improving construction efficiency.
[0052] After adjusting the position of the upper support member 200, when using the limiting component 400 to limit the distance between the lower support member 100 and the upper support member 200, one or two second locking nuts 412 on the locking screw 411 are turned to push the two limiting blocks 420 closer together, so that the limiting blocks 420 press against the lower support member 100 and the upper support member 200, thereby limiting the distance between the lower support member 100 and the upper support member 200. Furthermore, the limiting blocks 420 can also increase the strength of the temporary support for the bridge formwork in this embodiment, preventing the temporary support from being crushed or damaged due to insufficient strength during construction, ensuring the normal progress of bridge construction. When removing the temporary support, the second locking nut 412 is turned in the opposite direction while the positioning nut 340 is turned downwards, causing the upper support member 200 to move downwards under its own weight. Alternatively, construction personnel can manually or use tools to move the two limiting blocks 420 apart so that the upper support member 200 can move downwards to remove the temporary support in this embodiment.
[0053] like Figure 1As shown, in this embodiment, the sides of each limiting block 420 that abut against the lower support 100 and the upper support 200 are not parallel, so that when the second locking nut 412 pushes the two limiting blocks 420 closer together, the lower support 100 and the upper support 200 can move away from each other. When the two limiting blocks 420 approach each other, a component force perpendicular to the moving direction of the limiting blocks 420 is generated, which acts on the lower support 100 and the upper support 200 respectively, further enabling the lower support 100 and the upper support 200 to move away from each other. Figure 1 As shown, the frontal projection of each limiting block 420 is trapezoidal. In order to match the trapezoidal limiting block 420, the two planes of the lower support member 100 and the upper support member 200 that contact the limiting block 420 are also not parallel.
[0054] To simplify and facilitate processing, both the lower support 100 and the upper support 200 are made of steel plates that are cut and welded together, allowing the lower support 100, the upper support 200, and the two limiting blocks 420 to be assembled to form a rectangular outer contour. This processing method is simple, low-cost, and economical.
[0055] like Figure 3 As shown, in this embodiment, each limiting block 420 has a through hole 421. The two ends of the locking screw 411 pass through the through holes 421 of the two limiting blocks 420 respectively and are threadedly connected to the second locking nut 412. The locking screw 411 passes through the through holes 421 on the limiting blocks 420, which can easily connect the two limiting blocks 420. The through holes 421 provide a positioning function for the installation of the locking screw 411, making the installation of the locking screw 411 simple and quick, and reducing the assembly difficulty.
[0056] To reduce the processing cost of the limiting block 420, steel plates can be cut and welded to form a limiting block 420 with a trapezoidal shape when viewed from the front. In this case, the limiting block 420 is a box with a through hole 421 formed on the box wall so that the locking screw 411 can pass through the box.
[0057] Example 2
[0058] This embodiment is another installation method for the temporary support in Embodiment 1, the difference being:
[0059] In this embodiment, when temporary support is needed for concrete structures such as box girders and abutments that require construction in open areas during bridge construction, the temporary supports are pre-assembled and placed in the pre-set support positions. Then, the second locking nut 412 in the limiting component 400 is adjusted to push the two limiting blocks 420 closer together. Under the pushing force of the limiting blocks 420, the lower support 100 and the upper support 200 move away from each other. After the top elevation of the upper support 200 is adjusted to the predetermined height, the upper fixing member 330 on the upper support 200 is fixed to the support rod 310 using the positioning nut 340 and the first locking nut 350. This installation sequence can also install the temporary supports in place.
[0060] It should be noted that the structural components in this embodiment are the same as those in Embodiment 1. The only difference between this embodiment and Embodiment 1 is the installation sequence of some structures in the temporary support.
[0061] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.

A simplified temporary formwork support according to claim 8, characterized in that, Each of the limiting blocks (420) abuts against the two sides of the lower support (100) and the upper support (200) respectively, which are not parallel, so that when the second locking nut (412) pushes the two limiting blocks (420) closer to each other, the lower support (100) and the upper support (200) can move away from each other.
10. A simplified temporary formwork support according to claim 8 or 9, characterized in that, Each of the limiting blocks (420) has a through hole (421), and the two ends of the locking screw (411) pass through the through holes (421) of the two limiting blocks (420) respectively and are threadedly connected to the second locking nut (412).
