Description

Technical Field

[0001] This utility model relates to the technical field of tunnel engineering construction equipment, and in particular to a longitudinal waterstop positioning clamp. Background Technology

[0002] Currently, the invert arch is a crucial structural component at the tunnel bottom, playing a vital role in distributing the load from the superstructure and enhancing the overall stability of the tunnel. Simultaneously, installing waterstops within the invert arch presents a significant challenge in tunnel waterproofing and drainage construction. The invert arch and waterstop work together to ensure both the tunnel's safety and waterproofing performance.

[0003] In tunnel construction, the first step is to tie the reinforcing steel bars and install the formwork for the invert arch. When installing the formwork, the installation position of the waterstop is reserved at the joint between the invert arch and other lining structures. Then, before the invert arch concrete is poured, the waterstop is placed in the reserved position and fixed with positioning clamps to ensure that the waterstop is laid evenly along the joint without twisting or shifting.

[0004] However, the existing positioning clamps are complex in structure, do not securely fix the waterstop, and are inconvenient to disassemble. This makes it difficult to control the exposed height of the waterstop during the pouring process, and it is prone to folding and deformation. As a result, the waterstop cannot play its role in fixing and shaping during the pouring and compaction of concrete, which ultimately seriously reduces the quality of waterproofing construction. Utility Model Content

To this end, this utility model proposes a longitudinal waterstop positioning clamp to optimize the structure of the positioning clamp, facilitate adjustment of the exposed height of the waterstop, and prevent deformation of the waterstop.

[0015] The locking fastener is configured as a threaded screw with a threaded outer peripheral wall. The locking fastener passes through the through hole and can be used to control the contraction or release of the opening of the clamping plate.

[0016] According to the present invention, a longitudinal waterstop positioning clamp is provided, wherein the locking fastener has a butterfly-shaped cantilever for manual operation at one end of the screw, forming a T-shaped structure.

[0033] In tunnel construction, the invert arch and the waterstop are two crucial components that work together to ensure the tunnel's structural stability and waterproofing performance. Furthermore, installing the waterstop within the invert arch is both a key focus and a challenging aspect of tunnel waterproofing and drainage construction.

[0034] An invert is a structural component at the bottom of a tunnel, typically located at the bottom of the tunnel lining. The invert connects the sidewalls on both sides of the tunnel, forming a closed ring structure. The invert effectively distributes the load from above (such as rock pressure and vehicle loads) to the surrounding rock, thereby reducing the burden on the tunnel lining, enhancing the overall stability of the tunnel, and preventing deformation or collapse.

[0035] Meanwhile, the waterstop has a certain degree of elasticity, which can adapt to the slight deformation of the tunnel lining caused by temperature changes, foundation settlement and other reasons. Through the elasticity and sealing performance of the waterstop itself, it prevents groundwater from seeping into the tunnel from the lining joints and keeps the tunnel dry.

[0036] In tunnel construction, the first step is to tie the reinforcing steel bars and install the formwork for the invert arch. When installing the formwork, the installation position of the waterstop is reserved at the joint between the invert arch and other lining structures. Then, before the invert arch concrete is poured, the waterstop is placed in the reserved position and fixed with positioning clamps to ensure that the waterstop is laid evenly along the joint without twisting or shifting.

[0037] However, the existing positioning clamps are complex in structure, do not securely fix the waterstop, and are inconvenient to disassemble. This makes it difficult to control the exposed height of the waterstop during the pouring process, and it is prone to folding and deformation. As a result, the waterstop cannot play its role in fixing and shaping during the pouring and compaction of concrete, which ultimately seriously reduces the quality of waterproofing construction.

[0038] To address the aforementioned problems, an embodiment of this utility model introduces a longitudinal waterstop positioning clamp.

[0039] like Figure 1 As shown, the positioning fixture includes a first frame 100, a second frame 200, and a clamping assembly 230 for clamping the waterstop 300.

[0040] Specifically, the first frame 100 has a seat rod 110 extending in a straight line to provide support. The second frame 200 has a plurality of parallel and spaced-apart support plates 210. One end of each support plate 210 is rotatably connected to the seat rod 110. The second frame 200 also has a support rod 220 fixedly connected to the other end of each support plate 210, and the support rod 220 is parallel to the seat rod 110.

[0041] The support rod 220 is provided with a clamping assembly 230 for holding the waterstop 300. The rotation of the support rod 220 relative to the first frame 100 can cause the waterstop 300 to change position.

[0042] Furthermore, the main body of the positioning fixture is made of high-strength steel or aluminum alloy, which has good pressure resistance and corrosion resistance.

[0043] In this embodiment, the positioning clamp is configured such that the second frame 200 is rotatably connected to the first frame 100, and multiple clamping components 230 are fixed together by the support rod 220 to form an integrated support system. This not only enhances the stability and reliability of the positioning clamp, but also allows for convenient and stable adjustment of the height of the waterstop 300 by rotating the second frame 200 relative to the first frame 100, facilitating disassembly, assembly, and maintenance.

[0044] Based on the above embodiments, another embodiment of this utility model introduces a longitudinal waterstop positioning clamp.

[0045] like Figure 1 As shown, the clamping assembly 230 includes a clamping plate 231, which is formed by folding a plate to create an open structure in which a first clamping piece 232 and a second clamping piece 233 are connected at one end and separated at the other end.

[0046] The clamping plate 231 is fixed to the support rod 220. Furthermore, the opening size of the clamping plate 231 gradually increases from the farthest point to the nearth of the support rod 220.

[0047] In this embodiment, the clamping plate 231 is designed with an adjustable opening size, which can accommodate waterstops 300 of different widths and ensure their stable installation.

[0048] Based on the above embodiments, another embodiment of this utility model introduces a longitudinal waterstop positioning clamp.

[0049] The clamping assembly 230 also includes a locking fastener 235 connected to the clamping plate 231. The locking fastener 235 is installed near the open end of the clamping plate 231 to enhance the clamping force on the waterstop 300.

[0050] Based on the above embodiments, another embodiment of this utility model introduces a longitudinal waterstop positioning clamp.

[0051] A through hole 234 is provided on the clamping plate 231. The through hole 234 passes through the first clamping piece 232 and the second clamping piece 233.

[0052] The locking fastener 235 is configured as a threaded screw with a threaded outer peripheral wall. The locking fastener 235 passes through the through hole 234 and can be used to control the contraction or release of the opening of the clamping plate 231.

[0053] Furthermore, the locking fastener 235 has a butterfly-shaped cantilever for manual operation at one end of the screw, forming a T-shaped structure.

[0054] Based on the above embodiments, another embodiment of this utility model introduces a longitudinal waterstop positioning clamp.

[0055] The through hole 234 is threaded at the first clamping piece 232. Alternatively, the first clamping piece 232 is provided with a nut whose central axis coincides with that of the through hole 234, for engaging the locking fastener 235.

[0056] Furthermore, a plurality of clamping assemblies 230 are provided along the extension direction of the support rod 220 to distribute the supporting force evenly along the extension direction of the positioning clamp, thereby preventing the waterstop 300 from deforming.

[0057] Based on the above embodiments, another embodiment of this utility model introduces a longitudinal waterstop positioning clamp.

[0058] A rib plate 120 is provided on the seat rod 110. The rib plate 120 protrudes from the top of the seat rod 110 and extends vertically upward, and the support plate 210 is rotatably connected to the rib plate 120.

[0059] Furthermore, the support plate 210 and the rib plate 120 are respectively provided with pin holes 130, and the support plate 210 and the rib plate 120 are rotatably connected through the pin holes 130.

[0060] Preferably, the support plate 210 is arranged perpendicular to the support rod 220.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it.
