Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, specifically to a waterstop clamp for a tunnel invert arch. Background Technology

[0002] During tunnel construction, due to reasons such as the inability to pour continuously, foundation deformation, or thermal expansion and contraction of concrete components caused by temperature changes, construction joints, settlement joints, and deformation joints need to be left. Water control strips must be installed at these joints to prevent water leakage.

[0003] When fixing existing waterstops, due to the different placement positions of the waterstops and the different heights of the waterstops above the concrete layer, corresponding clamps need to be installed to fix the waterstops. This not only increases the workload, but also makes disassembly and assembly inconvenient and prevents reuse. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a tunnel invert arch waterstop clamp that can clamp waterstops of different extension heights in a centered manner. At the same time, the clamping position can be adjusted according to the position of the waterstop. It can be reused, which greatly improves the convenience of use and can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tunnel invert arch waterstop clamp, comprising:

[0006] The bottom block is fixed to the upper end of the invert arch formwork;

[0007] A vertical cylinder is fixed to the upper end of the base block;

[0008] A vertical adjustment rod is installed inside the vertical cylinder and its height position can be adjusted within the vertical cylinder;

[0009] A horizontal adjusting rod is disposed at the upper end of the vertical adjusting rod and is perpendicular to the vertical adjusting rod; the horizontal adjusting rod can move in the horizontal direction.

[0010] There are two clamps, both of which are fitted onto the outer side of the horizontal adjusting rod to clamp the waterstop.

[0011] As a preferred embodiment of this utility model, the vertical cylinder is provided with an internal thread, the outer side of the vertical adjusting rod is provided with an external thread, and the vertical adjusting rod is threadedly connected inside the vertical cylinder.

[0012] As a preferred embodiment of this utility model, the outer side of the vertical adjusting rod is threaded with an adjusting nut for fixing the position of the vertical adjusting rod.

[0013] As a preferred embodiment of this utility model, a fixing nut is welded to the upper end of the vertical adjusting rod, an external thread is provided on the outer side of the horizontal adjusting rod, and one end of the horizontal adjusting rod is threaded into the fixing nut.

[0014] As a preferred embodiment of this utility model, the outer side of the horizontal adjusting rod is threaded with two locking nuts, which are respectively disposed on one side of the two clamping plates for fastening the clamping plates.

[0015] As a preferred technical solution of this utility model, the bottom block is provided with an elongated oval countersunk hole, and is connected to the inverted arch template by a fixing bolt passing through the elongated oval countersunk hole.

[0016] As a preferred embodiment of this utility model, the clamping plate is made of steel.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: The tunnel invert arch waterstop clamp is reasonably designed and ingeniously conceived. By setting a vertical adjustment rod, the height position of the clamp plate can be adjusted, and the waterstops extending from different heights of the concrete layer can be clamped in the center. By setting a horizontal adjustment rod, it is convenient to quickly install the horizontal adjustment rod on the upper end of the vertical adjustment rod. By fitting the clamp plate 9 onto the horizontal adjustment rod, the horizontal position of the clamp plate can be adjusted, and the clamp can be clamped and fixed according to the distance of the waterstop from the side of the tunnel. This greatly improves the convenience of use, is easy to install, can be reused, and reduces the workload of workers. Attached Figure Description

[0022] Please see Figure 1-2This utility model provides a technical solution: a tunnel invert arch waterstop clamp, including a bottom block 3, a vertical cylinder 4, a vertical adjusting rod 5, a horizontal adjusting rod 6, and a clamping plate 9;

[0023] The bottom block 3 is fixed to the upper end of the invert arch formwork 1, and the vertical cylinder 4 is fixed to the upper end of the bottom block 3. The vertical cylinder 4 has internal threads, and the outer side of the vertical adjusting rod 5 has external threads. The vertical adjusting rod 5 is threaded into the vertical cylinder 4. By rotating the vertical adjusting rod 5, the height position of the clamping plate 9 can be adjusted to center and clamp the waterstop plate extending from the concrete layer. The upper end of the vertical adjusting rod 5 is welded with a fixing nut 7. The outer side of the horizontal adjusting rod 6 has external threads, and one end of the horizontal adjusting rod 6 is threaded into the fixing nut 7. The other end of the horizontal adjusting rod 6 is fitted with two clamping plates 9. By rotating the horizontal adjusting rod 6 and moving the position of the clamping plates 9, the waterstop 2 at different positions from the tunnel side can be clamped and fixed. To ensure clamping strength, the clamping plates 9 are made of steel.

[0024] Furthermore, in order to facilitate fixing the position of the vertical adjustment rod 5, an adjusting nut 10 is threadedly connected to the outer side of the vertical adjustment rod 5.

[0025] Furthermore, in order to ensure the clamping ability of the clamping plate 9 on the waterstop 2, two locking nuts 8 are threadedly connected to the outer side of the horizontal adjusting rod 6. The two locking nuts 8 are respectively set on one side of the two clamping plates 9, and the clamping plates 9 clamp and fix the waterstop 2 through the locking nuts 8.

[0026] To facilitate the installation of this fixture, an oblong countersunk hole 11 is provided on the bottom block 3. The fixture is connected to the arch template 1 by fixing bolts passing through the oblong countersunk hole 11, thereby improving the ease of installation.

[0027] In use: Fix multiple clamps to the upper end of the arch template 1 with bolts, screw the vertical adjusting rod 5 into the vertical cylinder 4, then screw the horizontal adjusting rod 6 into the fixing nut 7 at the upper end of the vertical adjusting rod 5, put two clamping plates 9 on the horizontal adjusting rod 6 and screw in two locking nuts 8, and adjust the screwing depth of the vertical adjusting rod 5 into the vertical cylinder 4 to ensure that the clamping plates 9 clamp the waterstop 2 in the center, and then tighten the two locking nuts 8 to complete the fastening of the waterstop 2.

[0028] The present invention uses a threaded connection to facilitate the quick installation of the fixture, reducing the workload of workers. At the same time, the thread adjustment can achieve the centering and clamping of the waterstop 2 at different positions, improving its versatility.
