Description

Technical Field

[0001] This invention relates to the field of bridge construction technology, and in particular to a bridge bracket system. Background Technology

[0002] Bridge construction typically employs a temporary support system. This involves first supporting the bridge's crossbeams with the support system, then installing and fixing the crossbeams before dismantling the support system to complete the crossbeam installation. Traditional support systems involve pre-embedding large steel plates within the bridge piers, welding the support system together under the bridge, and then hoisting individual support systems above the steel plates and welding them to the pre-embedded plates. However, this traditional installation process involves high-altitude vertical welding, making it difficult to guarantee weld quality and posing safety hazards. High-altitude welding is also labor-intensive and time-consuming. Furthermore, dismantling the support system requires gas welding to cut it from the pre-embedded steel plates, which is difficult and leaves the system severely damaged, making it unusable multiple times. Additionally, existing support systems lack dedicated standing space for construction workers, usually requiring the temporary construction of a platform. This temporary platform has limited area, causing inconvenience for workers. Summary of the Invention

[0003] The main objective of this invention is to provide a bridge bracket system that addresses the technical problems of existing bracket systems, such as safety hazards, long installation periods, difficult dismantling, and the lack of dedicated space for construction workers to stand, which causes inconvenience to construction workers.

[0004] To achieve the above objectives, the present invention proposes a bridge bracket system, wherein the bridge includes crossbeams, and the bracket system comprises:

[0005] A supporting chassis is provided with two walkways on the top of the supporting chassis. The two walkways are arranged laterally at intervals and are located near both ends of the supporting chassis, respectively.

[0006] A connecting assembly is located between the two walkways and includes a connecting column, a first connecting member, and a second connecting member. The connecting column is mounted on the supporting chassis. The first connecting member includes a first connecting rod and a hook. The lower end of the first connecting rod is detachably connected to the connecting column, and the hook is connected to the upper end of the first connecting rod. The crossbeam has a hook hole, and the hook engages with the hook hole to position the crossbeam laterally and longitudinally. The second connecting member includes a second connecting rod and a limiting rod that are interconnected. The second connecting rod is connected to the first connecting rod, and the crossbeam also has a limiting hole. The limiting rod extends into the limiting hole to position the crossbeam vertically and laterally.

[0007] Optionally, each walkway is a wooden board laid flat on the supporting chassis, and each walkway is provided with a guardrail on the side away from the other walkway, and a toe board is provided on the bottom of the guardrail facing the other guardrail.

[0008] Optionally, the first connecting rod is vertically arranged and located on one side of the crossbeam, the hook bends downward from the upper end of the first connecting rod, and the hook and the first connecting rod form a placement space, the second connecting rod is vertically arranged and extends into the placement space, and one side of the second connecting rod is connected to the first connecting rod, the limiting rod is longitudinally arranged, and the limiting rod is connected to the side of the second connecting rod away from the first connecting rod.

[0009] Optionally, the first connecting rod and the hook are integrally formed; and / or, the second connecting rod and the limiting rod are integrally formed.

[0010] Optionally, the supporting chassis includes multiple supporting layers stacked one on top of the other, and the connecting column runs through and is installed on at least one of the supporting layers from top to bottom; each of the walkways is located on the top of any one of the supporting layers, and the connecting column is located between two of the walkways.

[0011] Optionally, the number of support layers is three, namely a first support layer, a second support layer, and a third support layer stacked sequentially from top to bottom. The first support layer and the second support layer each have two interconnected threaded holes. The connecting post is a threaded post that passes through the two threaded holes in sequence and is threaded into each of the threaded holes. The bracket system also includes a nut, which is threadedly connected to the connecting rod and abuts against the bottom of the third support layer. Both walkways are located on the top of the third support layer.

[0012] Optionally, the upper end of the threaded column extends out of the first support layer, and an external thread is provided on the first connecting rod near its lower end. The lower end of the first connecting rod is connected to the upper end of the threaded column through a sleeve threaded with an internal thread.

[0013] Optionally, the third support layer is an I-beam layer, the second support layer is a square timber layer, and the first support layer is a bamboo plywood layer.

[0014] Optionally, the I-beam layer includes multiple I-beams spaced laterally, and each I-beam extends longitudinally; the square timber layer includes multiple square timbers spaced longitudinally, and each square timber extends laterally; and the bamboo plywood layer is a bamboo plywood laid flat on the side of the multiple square timbers facing away from the I-beams.

[0015] Optionally, there are multiple connecting components, which are spaced apart and arranged in a horizontal and vertical array between the two walkways.

[0016] In use, the bridge bracket system of this invention involves installing a support chassis at a designated location and mounting connecting columns on the support chassis. A first and second connecting member are used to connect to the crossbeam. The crossbeam has hook holes and limiting holes. The hook of the first connecting member engages with the hook holes to position the crossbeam laterally and longitudinally; the limiting rod of the second connecting member extends into the limiting holes to position the crossbeam vertically and laterally. The first and second connecting members, connected to the crossbeam, are connected to the connecting columns via the lower end of the first connecting member, thus mounting the crossbeam onto the bracket system. After use, the connecting columns are disconnected from the first connecting member, and the support chassis and connecting columns are removed, completing the dismantling of the bracket system. The first connecting member and connecting column of the bridge bracket system of this invention are detachably connected, avoiding the need for high-altitude welding operations and eliminating the safety hazards of unreliable weld quality. The detachable connection method offers the advantage of convenient installation, thereby reducing labor intensity and shortening the construction period. Furthermore, the construction process does not damage the supporting chassis during the use of the bracket system, allowing the chassis to be reused and thus saving on bridge construction costs. Additionally, walkways are provided on both sides of the connecting components, allowing construction workers to move freely and facilitating construction, thereby improving the flexibility of the bracket system.

[0027] This invention proposes a bridge bracket system.

[0028] In one embodiment, such as Figure 1 and Figure 2As shown, the bridge includes a crossbeam 200, and the bracket system includes a support chassis 10 and a connecting assembly 20. Two walkways 50 are provided on the top of the support chassis 10, spaced laterally and located near both ends of the support chassis 10. The connecting assembly 20 is located between the two walkways 50 and includes a connecting column 21, a first connector 22, and a second connector 23. The connecting column 21 is installed on the support chassis 10, and the first connector 22 includes a first connecting rod 221 and a hook 222. The lower end of the first connecting rod 221 is detachably connected to the connecting column 21. The hook 222 is connected to the upper end of the first connecting rod 221. The crossbeam 200 has a hook hole. The hook 222 hooks into the hook hole and positions the crossbeam 200 laterally and longitudinally. The second connecting member 23 includes a second connecting rod 231 and a limiting rod 232 that are connected to each other. The second connecting rod 231 is connected to the first connecting rod 221. The crossbeam 200 also has a limiting hole. The limiting rod 232 extends into the limiting hole and positions the crossbeam 200 vertically and laterally.

[0029] In use, the bridge bracket system of this invention involves installing a support base 10 at a designated position and mounting a connecting column 21 on the support base 10. A first connecting member 22 and a second connecting member 23 are used to connect the system to a crossbeam 200. The crossbeam 200 has hook holes and limiting holes. The hook 222 of the first connecting member 22 engages with the hook holes to position the crossbeam 200 laterally and longitudinally. The limiting rod 232 of the second connecting member 23 extends into the limiting holes to position the crossbeam 200 vertically and laterally. The first connecting member 22 and the second connecting member 23, which are connected to the crossbeam 200, are connected to the connecting column 21 via the lower end of the first connecting member 22, thus mounting the crossbeam 200 onto the bracket system. After use, the connecting column 21 is disconnected from the first connecting member 22, and the support base 10 and connecting column 21 are removed, completing the dismantling of the bracket system.

[0030] The first connecting member 22 and the connecting column 21 of the bridge bracket system of this invention are detachably connected, avoiding the need for high-altitude welding operations and eliminating the safety hazards of unreliable weld quality. The detachable connection method offers the advantage of convenient installation, thereby reducing labor intensity and shortening the construction cycle. Furthermore, the construction process does not damage the supporting chassis 10 during the use of the bracket system, allowing the supporting chassis 10 to be reused, thus saving on bridge construction costs. In addition, walkways 50 are provided on both sides of the connecting component 20, allowing construction personnel to move freely and facilitating construction work, thereby improving the flexibility of the bracket system.

[0031] In one embodiment, such as Figure 1As shown, each walkway 50 consists of wooden planks 52 laid flat on the supporting base 10, and each walkway 50 has a guardrail 51 on the side away from the other walkway 50. A toe board 511 is provided on the bottom side of the guardrail 51 facing the other guardrail 51. By setting up guardrails 51 and toe boards 511, the construction workers are prevented from falling from the walkways 50, thereby improving the safety and reliability of the bracket system.

[0032] In one embodiment, a first connecting rod 221 is vertically positioned on one side of the crossbeam 200. A hook 222 bends downward from the upper end of the first connecting rod 221, forming a placement space 223 between the hook 222 and the first connecting rod 221. A second connecting rod 231 is vertically positioned and extends into the placement space 223, with one side of the second connecting rod 231 connected to the first connecting rod 221. A limiting rod 232 is longitudinally positioned and connected to the side of the second connecting rod 231 opposite to the first connecting rod 221. The vertical positioning and extension of the second connecting rod 231 into the placement space 223 increases the contact area between the first connecting rod 221 and the second connecting rod 231, thereby improving the connection strength between the first connecting rod 221 and the second connecting rod 231, and thus improving the reliability of the bracket system. Furthermore, the second connecting rod 231 is welded to the first connecting rod 221, realizing the connection between the first connecting rod 221 and the second connecting rod 231, and welding has the advantage of reliable connection.

[0033] In one embodiment, the first connecting rod 221 and the hook 222 are integrally formed, which improves the strength of the first connecting member 22 and thus improves the reliability of the bracket system.

[0034] In one embodiment, the second connecting rod 231 and the limiting rod 232 are integrally formed, which improves the strength of the second connecting member 23 and thus improves the reliability of the bracket system.

[0035] In one embodiment, such as Figure 1 and Figure 2 As shown, the support chassis 10 includes multiple support layers stacked vertically. A connecting column 21 runs through and is installed in at least one support layer from top to bottom. Each walkway is located at the top of any one support layer, and the connecting column is located between two walkways. By setting multiple support layers, the load-bearing capacity of the support chassis 10 is improved, thereby enhancing the reliability of the bracket system.

[0036] Furthermore, the support system comprises three layers: a first support layer 11, a second support layer 12, and a third support layer 13, stacked sequentially from top to bottom. The first support layer 11 and the second support layer 12 each have two interconnected threaded holes. The connecting post 21 is a threaded post 21a, which passes through the two threaded holes and engages with them threadedly. The bracket system also includes a nut 30, which is threadedly connected to the connecting rod and abuts against the bottom of the third support layer 13. Both walkways 50 are located at the top of the third support layer 13. This three-layer support system effectively supports the connecting assembly 20 and the crossbeam 200, resulting in a rational structural design. Moreover, the two interconnected threaded holes in the first and second support layers 11, along with the threaded post 21a, facilitate the installation of the connecting post 21, further enhancing the structural design. Additionally, the nut 30, abutting against the bottom of the third support layer 13, prevents the connecting post 21 from wobbling, improving the reliability of the bracket system.

[0037] Furthermore, the upper end of the threaded post 21a extends out of the first support layer 11, and the first connecting rod 221 has an external thread near its lower end. The lower end of the first connecting rod 221 is threadedly connected to the upper end of the threaded post 21a through a sleeve 40 with an internal thread. When installing the sleeve 40, it can be first installed on the upper end of the threaded post 21a or the external thread of the first connecting rod 221. After splicing the upper end of the threaded post 21a with the lower end of the first connecting rod 221, the sleeve 40 is rotated until it is simultaneously threadedly connected to the external threads of both the upper end of the threaded post 21a and the lower end of the first connecting rod 221, thus connecting the threaded post 21a and the first connecting rod 221. Conversely, when disassembling, the threaded sleeve 40 is rotated until it is only threadedly connected to the external threads of either the upper end of the threaded post 21a or the lower end of the first connecting rod 221, thus disassembling the first connecting rod 221 and the threaded post 21a. This enables the detachable connection between the threaded column 21a and the first connecting rod 221, as well as the installation and disassembly of the bracket system. The structural design is ingenious and reasonable.

[0038] In one embodiment, the third support layer 13 is an I-beam 131 layer 13a, the second support layer 12 is a square timber 121 layer 12a, and the first support layer 11 is a bamboo plywood 111 layer 11a. Specifically, the bamboo plywood 111 has the advantages of high hardness, bending resistance, and compression resistance. The square timber 121 has the advantages of high stability and good nail-holding ability. The I-beam 131 has the advantages of low cost and high strength.

[0039] Furthermore, the I-beam 131 layer 13a includes multiple I-beams 131 spaced laterally, with each I-beam 131 extending longitudinally; the square timber 121 layer 12a includes multiple square timbers 121 spaced longitudinally, with each square timber 121 extending laterally; and the bamboo plywood 111 layer 11a consists of bamboo plywood 111 laid flat on the side of the multiple square timbers 121 facing away from the I-beams 131. By arranging multiple I-beams 131 and multiple square timbers 121 in a crisscross pattern, and laying bamboo plywood 111 on top of the square timbers 121, support for the crossbeam 200 is achieved, resulting in a more rational structural design.

[0040] In one embodiment, there are multiple connecting components 20, which are spaced apart and arranged in a horizontal and vertical array between two aisles 50. Two horizontally arranged connecting components 20 are used to jointly support a crossbeam 200, improving the connection effect with the crossbeam 200 and ensuring stable support of the crossbeam 200, thereby improving the reliability of the bracket system. Multiple vertically arranged connecting components 20 can be used to support the same crossbeam 200, further improving the reliability of the bracket system, or they can be used to support different crossbeams 200, improving the applicability and flexibility of the bracket system.

[0041] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made under the concept of the present invention using the description and drawings of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
