Description

Technical Field

[0001] This utility model relates to the field of foundation pit support technology, and in particular to a steel waler wing plate connecting device. Background Technology

[0002] In foundation pit or cofferdam engineering, steel walers are widely used as a key support component to ensure the stability of the pit or cofferdam sidewalls and prevent collapse during soil excavation. Steel walers possess high rigidity and strength, providing reliable rigid support for the sidewalls of the foundation pit or cofferdam, effectively resisting lateral soil pressure and ensuring safety during construction. Simultaneously, they connect with retaining piles, diaphragm walls, and other retaining structures to form a complete support system. This system transfers the soil pressure, water pressure, and other loads borne by the retaining structure to the internal support system or other stable support structures within the foundation pit, dispersing the load on the retaining structure, reducing its stress, and improving its safety. The use of steel walers offers advantages such as being environmentally friendly, reusable, having minimal impact on the surrounding environment, and being economical.

[0003] However, traditional waler connections primarily rely on welding, which has numerous drawbacks. Firstly, weld quality often fails to meet design requirements, resulting in insufficient stability and potential safety hazards under stress. Secondly, welding processes easily lead to material waste and low construction efficiency. Therefore, a new type of connector is urgently needed that ensures connection quality while allowing for reuse, thereby improving the construction quality and efficiency of foundation pit or cofferdam projects. Utility Model Content

[0030] Example 1

[0031] like Figures 1 to 4 As shown, an embodiment of a steel waler wing plate connecting device is provided. This wing plate connecting device includes a connecting plate 200 that abuts against the sidewalls of wing plates 100 on one or both sides of the steel waler structure. One end of the connecting plate 200 has a first engaging portion 300, and the other end has a second engaging portion 400. The first engaging portion 300 and the second engaging portion 400 are arranged opposite to each other. Both the first engaging portion 300 and the second engaging portion 400 are engaged with the wing plates at the steel waler joint. Specifically, the first engaging portion 300 is engaged at one end of the wing plate 100 in the vertical direction, and the second engaging portion 400 is engaged at the other end of the wing plate 100 in the vertical direction, used to withstand the combined effects of radial force, axial force, and shear force. In this embodiment, the structures of the first engaging portion 300 and the second engaging portion 400 can be the same or different; this is not limited, and those skilled in the art can determine the structure based on the thickness of the upper and lower edges of the wing plates. In this embodiment, the first snap-fit ​​part 300 and the second snap-fit ​​part 400 preferably have the same structure. It should be noted that the wing plate connecting device in this embodiment is provided on one or both sides of the steel waler, which can be determined according to the actual working conditions on site.

[0032] In this embodiment, both the first snap-fit ​​portion 300 and the second snap-fit ​​portion 400 are fixedly connected to the connecting plate 200, or they can be integrally formed. The first snap-fit ​​portion 300, the second snap-fit ​​portion 400, and the connecting plate 200 are preferably made of steel plate.

[0033] In use, before the two steel walers are joined, the first locking part 300 and the second locking part 400 need to be engaged with the wing plate of one of the steel walers. The connecting plate 200 is then moved to move the first locking part 300 and the second locking part 400 away from the joint of the steel walers. Then, the two steel walers are joined together, and the web plates at the joint are fixedly connected by the web plate connecting plate. Finally, the connecting plate 200 is moved to the joint of the wing plates of the two steel walers to complete the assembly. It should be noted that in this embodiment, the steel walers are joined under balanced forces during the process, and only the installation of the wing plate connecting device composed of the connecting plate 200, the first locking part 300, and the second locking part 400 is considered.

[0034] When disassembly is required, the web plate connecting plate is removed to separate the two mating steel walers. The moving connecting plate 200 drives the first locking part 300 and the second locking part 400 to move along the joint of the steel walers, so that the connecting plate 200, the first locking part 300 and the second locking part 400 are disengaged from the steel walers.

[0035] Furthermore, the first engaging portion 300 is provided with a first slot 310 capable of accommodating the edge of the wingplate, and the second engaging portion 400 is provided with a second slot 410 capable of accommodating the edge of the wingplate. The opening directions of the first slot 310 and the second slot 410 are arranged opposite to each other. Figure 4 As shown, when the first slot 310 and the second slot 410 are engaged with the edge of the wing plate, the inner wall of the connecting plate 200 is in contact with the outer wall of the wing plate, and a gap is left between the first slot 310 and the second slot 410 and the inner wall of the wing plate, so that the connecting plate 200, the first engaging part 300 and the second engaging part 400 can be pushed to move along the axial direction of the wing plate during installation, so as to achieve position adjustment.

[0036] In actual working conditions, taking the 2H700 type steel waler as an example, by connecting the steel waler wing plates to be connected using this embodiment, the welding length is reduced by 1700mm. Compared to the original 30-minute welding time for the steel waler wing plate connecting plate, this embodiment only requires 5 minutes to connect the steel waler wing plates to be connected, improving efficiency by 600%. After disassembly, this embodiment can be reused. Compared to the original wing plate connecting plate where materials are used only once, this embodiment can be reused more than 10 times.

[0037] Example 2

[0038] This embodiment is largely the same as Embodiment 1, except that, as Figures 5 to 10As shown, the first snap-fit ​​portion 300 is fixedly connected to the connecting plate or integrally formed. The connecting plate 200 has at least one second snap-fit ​​portion 400 at the end furthest from the first snap-fit ​​portion, and this second snap-fit ​​portion 400 is adjustable. By adjusting the second snap-fit ​​portion 400, the distance between the first snap-fit ​​portion 300 and the second snap-fit ​​portion 400 is adjusted, ensuring that the first snap-fit ​​portion 300 and the second snap-fit ​​portion 400 are securely snapped onto the wing plate at the steel waler joint. In this embodiment, two, three, or more second snap-fit ​​portions 400 can be selected, depending on the actual working conditions. If three or more second snap-fit ​​portions 400 are selected, the second snap-fit ​​portions 400 are linearly arrayed along the axial direction, ensuring stable force distribution on the connecting plate 200 during snap-fit. It should be noted that the first snap-fit ​​portion 300 and the multiple second snap-fit ​​portions 400 are arranged opposite to each other, and the length of the first snap-fit ​​portion 300 is greater than or equal to the length between the ends of the multiple snap-fit ​​portions 400, ensuring stable force distribution during snap-fit. For easy adjustment, multiple locking parts 400 can be connected in series to form a whole, making it easy to adjust at the same time.

[0039] In use, the first slot 310 on the first snap-fit ​​part 300 is snapped onto the upper edge of the wing plate 100, and the second snap-fit ​​part 400 is adjusted so that the second slot 410 is snapped onto the lower edge of the wing plate 100 and fixed, so that the connecting plate 200 is fixed and attached to the wing plate.

[0040] Furthermore, such as Figure 6 and Figure 7 As shown, the second latching portion 400 includes a latching member 420 and a locking assembly 430. The locking assembly 430 is vertically disposed on the first sliding groove 210 of the connecting plate 200. The second latching groove 410 is disposed on the latching member 420, and the second latching groove 410 can also be formed between the latching member 420 and the connecting plate 200. The latching member 420 is disposed on the top of the locking assembly 430, and the locking assembly 430 drives the latching member to move vertically. The first sliding groove 210 corresponds one-to-one with the second latching portion 400. The latching member 420 is L-shaped and can move up and down along the first sliding groove 210 to adjust the distance between the second latching groove 410 and the first latching groove 410.

[0041] In use, the first locking part 300 is engaged with the upper edge of the wing plate at the steel waler joint. The locking assembly 430 is then unlocked, and the locking assembly 430 is pushed to move the locking member 420 upwards until the locking member 420 is flush with the lower edge of the wing plate at the steel waler joint, locking the locking assembly 430 in place. At this point, the locking assembly 430 is fixed to the connecting plate 200, providing support for the wing plate 100.

[0042] Furthermore, the locking assembly 430 includes a first clamping member 431, a second clamping member 432, and a locking member 433. The locking member 433 is detachably connected to the first clamping member 431, the second clamping member 432, and the connecting plate 200, such that the first clamping member 431 and the second clamping member 432 are clamped on the inner and outer sides of the connecting plate, and the first clamping member 431 and the second clamping member 432 abut against the bottom of the snap-fit ​​member. In this embodiment, the locking member 433 can preferably be connected by a bolt and nut assembly. The first clamping member 431 and the locking member 433 can be integrally set or separately set. When set separately, the first clamping member 431 has a countersunk hole, and the locking member 433 passes axially through the first sliding groove 210 and the second clamping member 432, and is locked by a threaded connection.

[0043] Furthermore, such as Figures 8 to 10 As shown, the first clamping member 431 and the second clamping member 432 are slidably disposed on the snap-fit ​​member 420 along the direction perpendicular to the connecting plate. The first clamping member 431 and the second clamping member 432 move toward each other until the first clamping member 431 is in contact with the outer side of the wing plate and the second clamping member 432 is in contact with the inner side of the wing plate. The locking member 433 locks them in place to achieve fixation.

[0044] Furthermore, the snap-fit ​​member 420 is provided with a second sliding groove 421 along the direction perpendicular to the connecting plate, and the top of the first clamping member 431 and the second clamping member 432 is provided with a slider 434, which is slidably disposed within the second sliding groove 421. In this embodiment, the second sliding groove 421 includes, but is not limited to, a T-shaped groove, and the slider 434 matches the second sliding groove 421, improving the ease of installation.

[0045] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
