Description

Technical Field

[0001] This utility model relates to the field of bridge deck construction technology, and in particular to a support device suitable for the flange of a steel-concrete composite beam. Background Technology

[0002] Steel-concrete composite beams are composite structural beams made of steel and concrete materials through specific construction and construction processes. Usually, after the precast bridge deck is installed, some concrete is poured. In order to avoid local buckling or deformation of the composite beam flange during concrete pouring, a support device is usually installed at the bottom of the composite beam flange.

[0003] The existing structures supporting the bridge deck and flanges of steel-concrete composite beam bridges are usually scaffolded, but the construction and dismantling of scaffolding is cumbersome and inconvenient. Furthermore, traditional scaffolding lacks sufficient support stiffness and elevation adjustment precision, which can easily lead to deformation or settlement of the bridge deck or flange formwork during concrete pouring, thereby reducing the forming quality of the bridge deck and flanges and compromising the integrity and durability of the bridge structure.

[0004] Therefore, there is an urgent need to propose a support device suitable for the flange of steel-concrete composite beams to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a support device suitable for the flange of a steel-concrete composite beam, which can reduce the difficulty of disassembly and assembly, improve reusability, enhance the support stability of the flange of the steel-concrete composite beam, and ensure the construction and building quality of the steel-concrete composite beam.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] This utility model proposes a support device suitable for the flange of a steel-concrete composite beam, comprising: at least two support structures, which are spaced apart and connected to each other along a first horizontal direction. Each support structure includes a support platform and at least two support components. The support platform extends along a second horizontal direction, which is perpendicular to the first horizontal direction. At least two support components are spaced apart along the second horizontal direction. Each support component includes a first support member and a second support member. The first support member is detachably disposed at the bottom of the second support member and is used to support the second support member. The top of the second support member is fixedly connected to the support platform, and the support platform can support the flange of the steel-concrete composite beam. A locking mechanism is disposed between adjacent support components within the same support structure. The locking mechanism includes a connector and an elastic buckle. The connector extends along the second horizontal direction and has elastic buckles at both ends along its length. The first end of the elastic buckle in the vertical direction can pass through the first support member and abut against the inner wall of the first support member, and the second end can pass through the second support member and abut against the inner wall of the second support member, so as to lock the first support member and the second support member.

[0008] Specifically, the elastic latch includes an elastic opening, a first bent portion, and a second bent portion. The first bent portion and the second bent portion are disposed on opposite sides of the elastic opening in the vertical direction. The elastic opening is connected to the connector and the opening faces away from the connector. Supporting the elastic opening in the second horizontal direction can increase the opening area of ​​the elastic opening, so as to drive the first bent portion to abut against the inner wall surface of the first support member, and drive the second bent portion to abut against the inner wall surface of the second support member.

[0009] More specifically, both the first and second bends are U-shaped and their openings are opposite to the openings of the elastic opening. The inner wall of the first support member is provided with a first limiting part, and the inner wall of the second support member is provided with a second limiting part. The support member abuts against the elastic opening in the second horizontal direction, which can drive the end of the first bend away from the elastic opening to abut against the first limiting part, and drive the end of the second bend away from the elastic opening to abut against the second limiting part.

[0010] Optionally, the locking mechanism further includes a supporting auxiliary component, which includes a sliding member, a limiting member, and a locking member. The connecting member has sliding members slidably disposed at both ends along its length direction. The limiting member is fixedly connected to the sliding members and disposed on the opening side of the elastic opening. The limiting member abuts against the elastic opening at both ends along the vertical direction. The sliding member can slide along the second horizontal direction to drive the limiting member to abut against the elastic opening. The locking member is used to lock the position of the sliding member relative to the connecting member.

[0011] Specifically, a strip hole is provided at one end of the connector near the elastic latch. The strip hole extends along the second horizontal direction and penetrates the height direction of the connector, and the sliding member can slide and engage with the strip hole.

[0012] Optionally, the support device further includes a connecting assembly, which includes a first connecting sleeve, a second connecting sleeve, a first threaded component, and a second threaded component. The first connecting sleeve is rotatably provided on the side of the first support component in the adjacent support structure that is close to each other, and the second connecting sleeve is rotatably provided on the side of the second support component in the adjacent support structure that is close to each other. The two ends of the first threaded component along its own axial direction are threadedly locked to the first connecting sleeve of the adjacent first support component, and the two ends of the second threaded component along its own axial direction are threadedly locked to the second connecting sleeve of the adjacent second support component.

[0013] For example, the support assembly also includes a connector, and both the first support and the second support are provided with a connector groove on their adjacent sides, and the connector can be inserted into the connector groove to connect the first support and the second support.

[0014] Specifically, the support platform, the first support component, and the second support component are all made of steel.

[0015] The beneficial effects of this utility model are:

[0016] This utility model proposes a support device suitable for the flange of a steel-concrete composite beam. A first support member is detachably mounted at the bottom of a second support member. This detachable connection reduces the difficulty of assembling and disassembling the support assembly, improving its efficiency. Adjacent support components within the same support structure are provided with elastic latches. When the elastic latch deforms elastically, its first end along the vertical direction abuts against the inner wall of the first support member, and its second end abuts against the inner wall of the second support member. A single elastic latch can lock the first and second support components of the same support assembly, improving the connection strength between them. Elastic latches are provided at both ends of the connector along its length. The connector and the elastic latches at both ends enable a stable connection between adjacent support components within the same support structure, improving the installation and positioning accuracy of the support structure in the second horizontal direction. The top of the second support member is fixedly connected to a support platform. Since the support platform supports the steel-concrete composite beam flange, a locking mechanism is provided to enhance the stability of the support platform's support for the steel-concrete composite beam flange. Furthermore, the stable connection of adjacent support components can be achieved through the elastic deformation of the elastic latches, significantly reducing the disassembly and assembly requirements for construction personnel, simplifying the overall disassembly and assembly process of the support structure, and enhancing the reusability of the support structure. Adjacent support components within a single support structure can be locked together by a locking mechanism, and the interconnection between adjacent support structures ensures the self-stability of the support device along the first and second horizontal directions, improving the overall support effect of the support platform on the flange of the steel-concrete composite beam, thereby ensuring the construction and building quality of the steel-concrete composite beam.

[0028] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] like Figures 1-4 As shown, this embodiment proposes a support device suitable for the flange of a steel-concrete composite beam, including at least two support structures 1 and a locking mechanism 2. The at least two support structures 1 are spaced apart and connected to each other along a first horizontal direction. Each support structure 1 includes a support platform 11 and at least two support components 12. The support platform 11 extends along a second horizontal direction, which is perpendicular to the first horizontal direction. The at least two support components 12 are spaced apart along the second horizontal direction. Each support component 12 includes a first support member 121 and a second support member 122. The first support member 121 is detachably disposed at the bottom of the second support member 122 and is used to support the second support member 122. The top of the second support member 122 is fixedly connected to the support platform 11, which can support the steel-concrete composite beam flange. The locking mechanism 2 is disposed between adjacent support components 12 within the same support structure 1. The locking mechanism 2 includes a connector 21 and an elastic buckle 22. The connector 21 extends along the second horizontal direction and is provided with elastic buckles 22 at both ends along its own length direction. The first end of the elastic buckle 22 in the vertical direction can pass through the first support member 121 and abut against the inner wall surface of the first support member 121, and the second end can pass through the second support member 122 and abut against the inner wall surface of the second support member 122, so as to lock the first support member 121 and the second support member 122.

[0030] In this embodiment, the first support member 121 is detachably disposed at the bottom of the second support member 122. The detachable connection between the two reduces the difficulty of disassembling and assembling the support assembly 12 and improves the efficiency of disassembly and assembly of the support assembly 12. An elastic latch 22 is provided between adjacent support assemblies 12 within the same support structure 1. When the elastic latch 22 elastically deforms, its first end along the vertical direction can abut against the inner wall surface of the first support member 121, and its second end can abut against the inner wall surface of the second support member 122. A single elastic latch 22 can lock the first support member 121 and the second support member 122 of the same support assembly 12, improving the connection strength between the first support member 121 and the second support member 122. Both ends of the connector 21 along its length direction are provided with elastic latches 22. With the help of the connector 21 and the elastic latches 22 at both ends of the connector 21, a stable connection between adjacent support assemblies 12 within the same support structure 1 can be achieved, improving the support stability and installation positioning accuracy of the support structure 1 in the second horizontal direction. The top of the second support member 122 is fixedly connected to the support platform 11, which supports the flange of the steel-concrete composite beam. Therefore, the locking mechanism 2 enhances the stability of the support platform 11 in supporting the flange of the steel-concrete composite beam. Furthermore, the stable connection between adjacent support components 12 can be achieved through the elastic deformation of the elastic buckle 22, significantly reducing the disassembly and assembly requirements for construction personnel, simplifying the overall disassembly and assembly process of the support structure 1, and enhancing the reusability of the support structure 1. Adjacent support components 12 within a single support structure 1 can be locked together by the locking mechanism 2, and adjacent support structures 1 are interconnected, ensuring the self-stability of the support device along the first and second horizontal directions, improving the overall support effect of the support platform 11 on the flange of the steel-concrete composite beam, and thus ensuring the construction and building quality of the steel-concrete composite beam.

[0031] Specifically, such as Figures 1-3As shown, the elastic latch 22 includes an elastic opening 221, a first bent portion 222, and a second bent portion 223. The first bent portion 222 and the second bent portion 223 are disposed on opposite sides of the elastic opening 221 in the vertical direction. The elastic opening 221 is connected to the connector 21 and its opening faces away from the connector 21. Supporting the elastic opening 221 in the second horizontal direction can increase the opening area of ​​the elastic opening 221, so that the first bent portion 222 abuts against the inner wall surface of the first support member 121, and the second bent portion 223 abuts against the inner wall surface of the second support member 122. When installing the elastic buckle 22, the construction personnel can manually push against the elastic opening 221 along the second horizontal direction, so that the elastic opening 221 will undergo elastic deformation due to the force, causing the first bending part 222 to abut against the inner wall surface of the first support member 121 and the second bending part 223 to abut against the inner wall surface of the second support member 122, so as to ensure that the elastic buckle 22 locks the first support member 121 and the second support member 122 of the same support component 12, and works with the connector 21 to achieve the connection effect of adjacent support components 12.

[0032] The first bending portion 222 and the second bending portion 223 can both be in the shape of an "I" or an "L". The ends of both near the elastic opening portion 221 are fixedly connected to the elastic opening portion 221. The "I" or "L" shape of the first bending portion 222 and the second bending portion 223 can increase the contact area with the support component 12 and enhance the connection stability between the elastic lock 22 and the support component 12.

[0033] The first bend 222 and the second bend 223 can both be U-shaped, and their openings are opposite to the opening of the elastic opening 221. A first limiting part 1211 is provided on the inner wall of the first support member 121, and a second limiting part 1221 is provided on the inner wall of the second support member 122. The support part 222, which is supported by the elastic opening 221 in the second horizontal direction, can drive the end of the first bend 222 away from the elastic opening 221 to abut against the first limiting part 1211, and drive the end of the second bend 223 away from the elastic opening 221 to abut against the second limiting part 1221. The U-shaped design of the first bend 222 and the second bend 223, combined with the structural design of the first limiting part 1211 and the second limiting part 1221, reduces the risk of the elastic lock 22 disengaging from the support assembly 12, ensures the connection strength of adjacent support assemblies 12 within the same support structure 1, and thus enhances the support stability of the support platform 11 on the steel-concrete composite beam flange.

[0034] In this embodiment, as Figures 1-3As shown, the locking mechanism 2 also includes a supporting auxiliary component 23, which includes a sliding member 231, a limiting member 232, and a locking member 233. The connecting member 21 has sliding members 231 slidably mounted at both ends along its length. The limiting member 232 is fixedly connected to the sliding members 231 and positioned on the opening side of the elastic opening 221. Both ends of the limiting member 232 abut against the elastic opening 221 in the vertical direction. The sliding member 231 can slide along the second horizontal direction to drive the limiting member 232 to abut against the elastic opening 221. The locking member 233 is used to lock the position of the sliding member 231 relative to the connecting member 21. After the supporting auxiliary component 23 is installed, the construction personnel can manually drive the sliding member 231 to slide along the second horizontal direction to achieve the limiting member 232 abutting against the elastic opening 221, thereby locking the elastic latch 22 against the first support member 121 and the second support member 122. Compared to manually supporting the elastic opening 221 to increase its opening area, the supporting auxiliary component 23 proposed in this embodiment significantly improves the supporting operation of the elastic opening 221 by construction personnel, reduces the difficulty of supporting, and improves the efficiency of the supporting operation. In addition, the locking member 233 is used to lock the position of the sliding member 231 relative to the connecting member 21 in the second horizontal direction, so that the limiting member 232 fixedly connected to the sliding member 231 can continuously and stably support the elastic opening 221 and maintain the opening area of ​​the elastic opening 221, avoiding the connection failure between adjacent support components 12 arranged in the second horizontal direction due to the elastic reset of the elastic opening 221.

[0035] In some embodiments, a slide rail along a second horizontal direction is provided on the surface of the connector 21, and the slider 231 can slide along the slide rail to improve sliding accuracy.

[0036] In some other embodiments, the connector 21 is provided with a strip hole 211 at one end near the elastic latch 22. The strip hole 211 extends along the second horizontal direction and penetrates the height direction of the connector 21. The slider 231 can slide and engage with the strip hole 211 to reduce the sliding cost of the slider 231 and the processing difficulty of the connector 21.

[0037] Specifically, the sliding member 231 may have a guide rod protruding along its height direction. The guide rod can slide and engage with the slotted hole 211, thereby enabling the sliding member 231 to slide along the second horizontal direction. The locking member 233 may be a nut that is threaded into the guide rod. Turning the nut can lock the guide rod to the connecting member 21. The locking member 233 may also be a locking block that can be placed in the slotted hole 211. The locking block occupies the sliding space of the guide rod, thereby restricting the sliding member 231 as a whole from sliding along the second horizontal direction.

[0038] Optionally, the support device further includes a connecting assembly 3, which includes a first connecting sleeve 31, a second connecting sleeve 32, a first threaded component 33, and a second threaded component 34. The first connecting sleeve 31 is rotatably mounted on the side of each adjacent first support member 121 in the adjacent support structure 1, and the second connecting sleeve 32 is rotatably mounted on the side of each adjacent second support member 122 in the adjacent support structure 1. The two ends of the first threaded component 33 along its own axial direction are threadedly locked to the first connecting sleeve 31 of the adjacent first support member 121, and the two ends of the second threaded component 34 along its own axial direction are threadedly locked to the second connecting sleeve 32 of the adjacent second support member 122. The threaded locking effect between the first threaded component 33 and the first connecting sleeve 31, and the threaded locking effect between the second threaded component 34 and the second connecting sleeve 32, improves the connection reliability of the adjacent support structures 1, reduces the overall assembly and disassembly difficulty of the support device, and also enables flexible adjustment of the spacing between adjacent support structures 1. It should be noted that the first connecting sleeve 31 will not detach from the first support member 121 when it rotates, and the second connecting sleeve 32 will not detach from the second support member 122 when it rotates.

[0039] Specifically, the connecting assembly 3 includes multiple first threaded parts 33 and multiple second threaded parts 34. Correspondingly, the first support member 121 is provided with multiple first connecting sleeves 31 spaced apart in the vertical direction, and the second support member 122 is provided with multiple second connecting sleeves 32 spaced apart in the vertical direction. The two ends of the first threaded parts 33 can connect to any first connecting sleeve 31 on the adjacent first support member 121, and the two ends of the second threaded parts 34 can connect to any second connecting sleeve 32 on the adjacent second support member 122. The multiple first threaded parts 33 and second threaded parts 34 further enhance the connection strength of adjacent support structures 1, thereby improving the overall load-bearing capacity of the support device. It is understood that a single first connecting sleeve 31 and a single second connecting sleeve 32 can be connected to at most one first threaded part 33. In this embodiment, the connecting assembly 3 includes two each of the first threaded parts 33, first connecting sleeves 31, second threaded parts 34, and second connecting sleeves 32. Figure 1 and Figure 4 As shown, the two first threaded parts 33 can be arranged in a cross configuration.

[0040] The first support member 121 and the second support member 122 can be connected by threaded locking. For example, both ends of the two members that are close to each other can be threaded, and rotating the second support member 122 can lock them together. Alternatively, the second support member 122 can be partially installed inside the first support member 121, and screws or bolts can be inserted into the overlapping parts of the two members, thereby improving the connection strength between the first support member 121 and the second support member 122. In this embodiment, the support assembly 12 also includes a connector 123. Both the first support member 121 and the second support member 122 have a connector groove on their close sides. The connector 123 can be inserted into the connector groove to connect the first support member 121 and the second support member 122. The connector 123 reduces the difficulty of connecting the first support member 121 and the second support member 122, and also improves the structural strength of the connection between the first support member 121 and the second support member 122, avoiding the risk of stress concentration at the connection.

[0041] For example, the support platform 11, the first support member 121 and the second support member 122 are all made of steel to improve the support strength of the support structure 1 and enhance the support stability of the support device on the steel-concrete composite beam flange.

[0042] Specifically, the installation process of the support device applicable to the flange of the steel-concrete composite beam is as follows: Fix the first support member 121 below the flange to be supported; insert the connector 123 into the top of the first support member 121 and insert the second support member 122 into the top of the connector 123; connect the first support member 121 and the second support member 122, so that the support platform 11 above the second support member 122 abuts against the flange; insert at least a portion of the elastic latch 22 into the first support member 121 and the second support member 122; operate the sliding member 231 to slide along the second horizontal direction; and limit the movement of the locking member 23. The first bending portion 222 abuts against the elastic opening 221, causing the second bending portion 223 to abut against the inner wall of the first support member 121, and the second bending portion 223 to abut against the inner wall of the second support member 122. The locking member 233 locks the position of the sliding member 231 to stably lock the adjacent support components 12 under the same support structure 1. The first connecting sleeve 31 is rotated until it is threadedly locked to the first threaded member 33, and the second connecting sleeve 32 is rotated until it is threadedly locked to the second threaded member 34 to install and fix the first threaded member 33 and the second threaded member 34, thereby realizing the connection between adjacent support structures 1. Compared with the prior art, which uses multiple threaded fasteners to connect the above components in sequence, the assembly process of the support device proposed in this embodiment is simplified, and the difficulty of disassembly and assembly is greatly reduced.

[0043] 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.
