[0002] In bridge engineering, the support structure is an important facility to ensure the smooth progress of bridge construction. Traditional bridge support structures mostly use wooden or steel scaffolding, which is cumbersome to set up and dismantle, and the support effect is unstable, posing safety hazards. Therefore, developing a bridge support structure and its supporting facilities with stable structure, convenient installation, good support effect, is of great significance to improving the efficiency and quality of bridge construction.

[0003] At present, there are some new bridge support structures on the market. In order to achieve stable support, the overall structure is relatively complex, which affects the subsequent disassembly and assembly process of temporary supports. Therefore, it is necessary to improve and innovate the existing bridge support structure to meet the actual needs of bridge engineering. Utility Model Content

[0004] In order to facilitate the disassembly and assembly of a temporary fixed support for a bridge, the present application provides a temporary fixed support for a bridge that is easy to disassemble and assemble.

[0005] The temporary fixed support for bridges provided in this application is convenient for disassembly and assembly and adopts the following technical solution:

[0006] A temporary fixed support for bridges that is easy to disassemble and assemble, includes a base, a plurality of brackets are connected to the upper side of the base, a distribution beam is provided on the upper side of the plurality of brackets, a plurality of distribution beams are provided on the upper side of the plurality of brackets, a plurality of sand boxes are provided on the upper side of the plurality of distribution beams, the plurality of sand boxes are arranged in one-to-one correspondence with the plurality of brackets, and each of the sand boxes is arranged on the upper side of the corresponding bracket.

[0007] By adopting the above technical solution, by setting up multiple brackets, setting a distribution beam on the upper side of the bracket, and setting a sandbox on the upper side of the distribution beam, on the one hand, it is possible to achieve stable support for the bridge from the bottom of the bridge, and on the other hand, when disassembly is required, the sandbox, distribution beam and bracket are removed in turn, which facilitates the disassembly process of the temporary fixed support and reduces the trouble of assembling and disassembling the fixed support.

[0008] Optionally, the bracket includes a plurality of connecting tubes arranged along the same vertical direction, the upper and lower ends of each connecting tube are fixedly connected with a flange, and two adjacent flanges are connected by a connecting piece.

[0013] By adopting the above technical solution, when a sandbox is needed to support a bridge, sand is poured into the interior of multiple bottom connecting plates according to the required support height, and then the top pressure plate is abutted against the sand inside the multiple bottom connecting plates, so that the top plate can abut against the required supporting bridge position while the bottom plate abuts against the distribution beam, thereby achieving support for the required supporting bridge position through the sandbox.

[0014] Optionally, a plurality of the bottom connecting plates are each provided with a sand outlet hole, and a blocking component for simultaneously blocking the plurality of the sand outlet holes is provided at the plurality of the sand outlet holes.

[0015] By adopting the above technical solution, by setting up sand outlet holes and sealing the sand outlet holes with sealing pieces, on the one hand, in the process of supporting the bridge, the position of sand inside multiple bottom connecting plates can be restricted by the sealing pieces, so that the sandbox can stably support the bridge; on the other hand, by opening the sealing pieces, the sand can flow out from the sand outlet holes, which facilitates the process of disassembling the sandbox.

DETAILED DESCRIPTION

[0032] Example 1

[0033] This embodiment discloses a temporary fixed support for a bridge that is convenient for disassembly and assembly: Figure 1 , including a base 1, and a reinforcement is arranged inside the base 1 to increase the bearing capacity of the base 1. The upper surface of the base 1 is horizontally arranged and connected with a plurality of brackets 2. In this embodiment, the number of brackets 2 is four, and the four brackets 2 are located on the upper side of the base 1 and are evenly distributed in a square shape.

[0034] Two groups of horizontally arranged distribution beams 3 are provided on the upper side of the bracket 2, and each group of distribution beams 3 is provided corresponding to two adjacent brackets 2, and each group of distribution beams 3 is located on the upper side of the corresponding two brackets 2. Each group of distribution beams 3 is provided with two oppositely arranged I-beams, and the lower side of each I-beam is fixedly connected to the upper end of the corresponding bracket 2.

[0035] Two oppositely arranged sand boxes 4 are arranged on the upper side of each group of distribution beams 3, and the four sand boxes 4 are arranged one by one with the four brackets 2, and each sand box 4 is arranged above the corresponding bracket 2. Each sand box 4 can be adjusted in height as needed.

[0036] A plurality of parallel transverse connecting plates 5 and an oblique connecting plate 6 capable of connecting two adjacent transverse connecting plates 5 are connected between two adjacent brackets 2 .

[0037] When temporary support of the bridge is required, the base 1 is placed on the lower side of the required support position, and then the bracket 2 is placed on the upper side of the base 1, and the distribution beam 3 and the sand box 4 are set. By adjusting the height of the sand box 4, the upper end of the sand box 4 can support the lower side of the bridge.

[0038] When the bracket 2 needs to be removed, the sandbox 4, the distribution beam 3 and the bracket 2 are removed and separated in sequence to realize the removal process of the entire fixed support, thereby facilitating the process of the staff removing the fixed support.

[0039] The bracket 2 includes a plurality of connecting tubes 21 arranged along the same vertical direction. The heights of the connecting tubes 21 are different. Connecting tubes 21 of different sizes such as 4.0m, 2.0m, 1.0m, 0.5m, 0.3m, 0.2m, and 0.1m can be selected as needed. The upper and lower ends of each connecting tube 21 are fixedly connected with flanges 22, and each flange 22 is arranged perpendicular to the length direction of the connecting tube 21. Two adjacent flanges 22 are connected by a connector 7. Each flange 22 is close to one side of the connected connecting tube 21 and is fixedly connected to the outer wall of the connected connecting tube 21 with a plurality of stiffening plates 23. The plurality of stiffening plates 23 connected to each flange 22 are evenly distributed around the outer wall of the connected connecting tube 21.

[0040] Reference Figure 2 In this embodiment, the connecting member 7 is a connecting bolt 71 , and the connecting bolt 71 is capable of simultaneously penetrating two adjacent flanges 22 and connecting with the two flanges 22 .

[0041] By arranging the bracket 2 to be composed of a plurality of connecting tubes 21, and the connecting tubes 21 being connected by flanges 22 and connectors 7, the bracket 2 can stably support the bridge while facilitating the subsequent disassembly and assembly process of the bracket 2, thereby facilitating the overall disassembly and assembly process of the bracket 2.

[0042] The flange 22 at the bottom is connected to the base 1 via chemical anchors.

[0043] Reference Figure 3 The sandbox 4 includes a horizontally arranged top plate 41, and a plurality of top vertical pipes 42 are fixedly connected to the lower surface of the top plate 41, and each top vertical pipe 42 is arranged vertically to the top plate 41. In this embodiment, four top vertical pipes 42 are arranged, and the four top vertical pipes 42 are evenly distributed in a square shape at the lower side of the top plate 41. A top connecting plate 43 for blocking the gap between two adjacent top vertical pipes 42 is fixedly connected between two adjacent top vertical pipes 42. A horizontally arranged top pressure plate 44 is fixedly connected to the side of the four top vertical pipes 42 away from the connected top plate 41.

[0044] A bottom plate 45 is provided on the side of the top pressure plate 44 away from the top plate 41, and a plurality of bottom vertical pipes 46 are fixedly connected to the side of the bottom plate 45 close to the top pressure plate 44. In this embodiment, four bottom vertical pipes 46 are provided, and the four bottom vertical pipes 46 are evenly distributed in a square shape and surround the top pressure plate 44. A bottom connecting plate 47 is fixedly connected between two adjacent bottom vertical pipes 46. Each bottom connecting plate 47 can block the gap between two adjacent bottom vertical pipes 46, and the lower side wall of each bottom connecting plate 47 is fixedly connected to the bottom plate 45.

[0045] When needed, sand is poured onto the upper side of the bottom plate 45 so that the top pressure plate 44 can be located inside the bottom connecting plates 47 and abut against the sand, thereby adjusting the position of the top plate 41 so that the top plate 41 can abut against the bridge.

[0046] The implementation principle of Example 1 of the present application is: according to the required height of the supported bridge, a connecting tube 21 of suitable size is selected and spliced ​​into four brackets 2 of equal height.

[0047] The base 1 is placed at the lower side of the required supporting bridge position, and then the bracket 2 and the base 1 are connected by chemical anchors, and then the distribution beam 3 is set on the upper side of the bracket 2. According to the support requirements, sand is placed inside the multiple bottom connecting plates 47, so that the top pressure plate 44 abuts against the sand inside the bottom connecting plate 47, and the upper side of the top plate 41 abuts against the required supporting bridge, so as to realize the supporting process of the bridge.

[0048] When dismantling is required, it is only necessary to release the sand inside the multiple bottom connecting plates 47 so that there is a gap between the top plate 41 and the bridge it abuts against, and then dismantle the sandbox 4, distribution beam 3 and bracket 2 in turn to complete the dismantling process of the fixed support.

[0049] Example 2

[0050] Reference Figure 4

[0051] The difference of this embodiment is that the connecting member 7 includes a connecting screw 72, which is fixedly connected to the flange 22 located at the lower side of the two adjacent flanges 22, and each connecting screw 72 is vertically arranged upward and penetrates the upper adjacent flange 22. The upper surface of the flange 22 located at the upper side of the adjacent two flanges 22 is rotatably connected with a connecting ratchet 73 corresponding to the adjacent connecting screw 72. Each connecting screw 72 penetrates the corresponding connecting ratchet 73 and is threadedly connected to the connecting ratchet 73. A connecting pawl 74 capable of being engaged with the adjacent connecting ratchet 73 is provided on one side of each connecting ratchet 73.

[0052] When it is necessary to connect the two connecting tubes 21, first fix the position of the connecting tube 21 on the lower side, then set the connecting tube 21 on the upper side relative to the connecting tube 21 on the lower side and make the flanges 22 at the end docked. During the docking of the two flanges 22, the connecting screw 72 passes through the flange 22 on the upper side and the connecting ratchet 73 and drives the connecting ratchet 73 to rotate. At this time, the connecting ratchet 73 is not engaged with the connecting pawl 74. In the subsequent support process, when the relative position between the two connecting tubes 21 becomes larger, the connecting pawl 74 is engaged with the connecting ratchet 73, making it difficult for the connecting ratchet 73 to rotate, and then making it difficult for the connecting screw 72 to move, thereby fixing the positions of the two adjacent flanges 22 and then limiting the relative position between the two connecting tubes 21.

[0053] Reference Figure 5 The bottom of each bottom connecting plate 47 is provided with a sand outlet hole 471 penetrating the bottom connecting plate 47. The plurality of sand outlet holes 471 are connected with a plugging assembly 8 for plugging the plurality of sand outlet holes 471.

[0054] By setting up the sand outlet hole 471 and the sealing assembly 8, it is convenient for the workers to discharge the sand inside the sand box 4 out of the multiple bottom connecting plates 47 during the process of dismantling the sand box 4, thereby creating a gap between the top plate 41 and the bridge it abuts against, thereby facilitating the workers to dismantle the fixed support.

[0055] The plugging assembly 8 includes a plugging block 81 plugged into the inside of a plurality of sand outlet holes 471, and the plugging block 81 is used to plug the sand outlet holes 471 to prevent fine sand from flowing out. Each plugging block 81 is fixedly connected to a vertically arranged plugging rod 82 at one end away from the bottom connecting plate 47. The upper ends of the plurality of plugging rods 82 are connected to the same plugging ring 83, which is arranged horizontally and made of rubber or other materials that can produce flexible deformation, and the setting of the plugging ring 83 enables the plurality of plugging rods 82 to move synchronously, thereby achieving simultaneous plugging or release of the plurality of sand outlet holes 471. An abutting ring 84 is arranged on the upper side of the plugging ring 83, and the outer side wall of the abutting ring 84 is gradually inclined from top to bottom toward the side close to the adjacent bottom connecting plate 47. This structural design enables the abutting ring 84 to be more easily inserted into the gap between the bottom connecting plate 47 and the plugging ring 83, thereby improving the sealing performance of the plugging assembly 8.

[0056] When the sand inside the multiple bottom connecting plates 47 needs to be released, the abutment ring 84 is moved downward, and the abutment ring 84 drives the sealing ring 83 and the multiple sealing rods 82 connected to the sealing ring 83 to move away from the adjacent bottom connecting plates 47. During the movement, the sealing rods 82 drive the connected sealing blocks 81 to move out from the sand outlet holes 471, so that the sand inside the bottom connecting plates 47 can flow out from the sand outlet holes 471, causing the top plate 41 to move downward.

[0057] Alternative solutions for filling inside the sandbox 4. In addition to fine sand, the sandbox 4 can also be filled with other fluid materials, such as crushed stone, gravel, etc. These alternative fillers can also adjust the height of the sandbox 4 by adjusting the filling amount, but factors such as fluidity and carrying capacity need to be considered when selecting.

[0058] The implementation principle of Example 2 of the present application is as follows: when it is necessary to connect two adjacent connecting tubes 21, first fix the position of the lower connecting tube 21, and then dock the upper connecting tube 21 with the lower connecting tube 21, so that the connecting screw 72 can be inserted into the connecting ratchet 73 and the position of the connecting ratchet 73 and the connecting screw 72 is restricted by the connecting pawl 74. When it is necessary to disassemble the two adjacent connecting tubes 21, move the connecting pawl 74 so that the connecting pawl 74 is no longer engaged with the connecting ratchet 73, and then pull the upper connecting tube 21 upward to realize the separation process of the two upper and lower adjacent connecting tubes 21.

[0059] During the process of disassembling the sandbox 4, the abutment ring 84 is moved downward so that the abutment ring 84 can drive multiple blocking blocks 81 to move out from the sand outlet hole 471, so that the sand inside the sandbox 4 flows out from the sand outlet hole 471, thereby causing a gap to appear between the top plate 41 and the abutted bridge, so that the sandbox 4 can be taken out from the bottom side of the bridge.

[0060] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
