Description

A waterstop positioning and straightening clamp Technical Field

[0001] This utility model relates to the field of tunnel arch construction technology, and in particular to a waterstop positioning and straightening clamp. Background Technology

[0002] In tunnel construction quality, tunnel waterproofing and drainage are key and challenging aspects, and the installation of tunnel waterstops is a crucial part of the tunnel waterproofing and drainage system. Currently, the conventional practice for installing tunnel waterstops is to weld opposing reinforcing bars to both sides of the waterstop for fixation. However, during concrete pouring and tamping, this can lead to the waterstop becoming serpentine, off-center, or uneven, or even embedded outside the invert arch and secondary lining concrete, failing to provide waterproofing for construction joints. If seepage or leakage occurs, it will significantly impact the tunnel's durability and usability.

[0003] Existing patent CN107130984A discloses a positioning clamp for a tunnel invert waterstop, including a U-shaped clamp for clamping the waterstop. The U-shaped clamp includes a fixed end and a clamping end, which are hinged together by a pin. The clamping end can rotate around the pin. Holes are provided at the upper part of both the fixed end and the clamping end, and hinge bolts are inserted into the two holes. The ends of the hinge bolts are threaded to the fixed end, and the fixed end and the clamping end are fastened together by the hinge bolts. A connecting part extending towards the inside of the invert is provided on the fixed end. The connecting part includes a first connecting rod connected to the fixed end and a second connecting rod fixedly connected to the invert forming mold. The first connecting rod and the second connecting rod are hinged together. A support plate is provided on the body of the second connecting rod, and an adjusting bolt is provided on the support plate. The end of the adjusting bolt is threaded to the body of the first connecting rod.

[0004] However, because the clamp does not have a straightening mechanism at the two ends of the waterstop, the waterstop cannot be fixed and may be bent or deformed. Utility Model Content

Detailed Implementation

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0022] First embodiment:

[0023] Please refer to Figures 1 to 3, where Figure 1 is a front view of the first embodiment of the present invention, Figure 2 is a cross-sectional view along line AA in Figure 1 of the present invention, and Figure 3 is a partial enlarged view of point B in Figure 2 of the present invention.

[0024] This utility model provides a waterstop positioning and straightening clamp, including a waterstop body 101, two clamping plates 102, an arch template 103, and multiple straightening mechanisms. The straightening mechanism includes multiple bolts 108 and straightening plates 109. The aforementioned solution solves the technical problem that the waterstop cannot be fixed properly because the clamp does not have straightening mechanisms at both ends, and the waterstop will also bend and deform.

[0025] In this specific embodiment, a column base 104 is provided on the arch template 103, a column body 105 is longitudinally provided on the column base 104, and a threaded rod 106 is transversely provided on the column body 105. Two locking nuts 107 are provided at the end of the threaded rod 106 away from the column body 105. The waterstop body 101 abuts against the corresponding clamp plate 102 and is located between the two clamp plates 102. The two clamp plates 102 are slidably connected to the threaded rod 106 and are sleeved on the threaded rod 106. The two locking nuts 107 abut against the waterstop body 101 and are located at both ends of the waterstop body 101. The two locking nuts 107 facilitate the abutment of the two clamp plates 102, thereby shortening the distance between the two clamp plates 102 and clamping and fixing the waterstop body 101.

[0026] The straightening mechanisms are symmetrically arranged in pairs on both sides of the clamping plate 102. One end of the straightening plate 109 has a groove 110. Both sides of the clamping plate 102 have slots 111. Each slot 111 has two sliders 112. Multiple bolts 108 are threadedly connected to the corresponding clamping plate 102 and are located in the slots 111, and also penetrate the waterstop body 101. The straightening plate 109 is slidably connected to the corresponding clamping plate 102 and is located in the corresponding slot 111. The sliders 112 are located in the grooves 110. The straightening plate 109 also abuts against the waterstop and is located on one side of the waterstop. The straightening plate 109 positions the waterstop body 101 in a linear direction, thereby ensuring the straightness and stability of the waterstop body 101 during construction and avoiding bending and deformation.

[0027] Secondly, a washer 113 is provided on the bolt 108, and the washer 113 abuts between the bolt 108 and the clamp plate 102. The washer 113 can improve the tightness of the connection between the bolt 108 and the clamp plate 102.

[0028] Furthermore, a rubber pad 114 is provided on the end face of the straightening plate 109, and the rubber pad 114 abuts against the straightening plate 109 and the waterstop. The rubber pad 114 can increase the friction between the rubber pad and the waterstop body 101, thereby preventing the waterstop body 101 from detaching from the straightening plate 109.

[0029] When straightening the waterstop body 101 using this utility model, the straightening plate 109 is inserted into the clamp plate 102, and then the bolt 108 is connected to the clamp plate 102 and passes through the straightening plate 109 using the special tool, thereby fixing the straightening plate 109. At the same time, the straightening plate 109 abuts against one side of the waterstop body 101, so that the waterstop body 101 is located between multiple straightening plates 109, thereby ensuring the straightness and stability of the waterstop body 101 during construction and avoiding bending and deformation. It should be noted that the straightening plate 109 in this design is made of steel, and its specific length is consistent with the waterstop body 101 used. This method solves the technical problem that the waterstop cannot be fixed due to the lack of a straightening mechanism at both ends of the clamp, and also causes the waterstop to bend and deform.

[0030] The second embodiment is as follows:

[0031] Based on the first embodiment, please refer to Figures 4 to 6, where Figure 4 is a front view of the second embodiment of the present invention, Figure 5 is a cross-sectional view along line CC in Figure 4 of the present invention, and Figure 6 is a partial enlarged view of point D in Figure 5 of the present invention.

[0032] This utility model provides a waterstop positioning and straightening clamp, which also includes a retaining ring 201 and multiple limiting components, the limiting components including a spring 202, a limiting rod 203 and a pulling block 204.

[0033] In this specific embodiment, the abutment ring 201 is slidably connected to the threaded rod 106 and sleeved on the threaded rod 106, and is also located between the two clamping plates 102. The abutment ring 201 can prevent the two clamping plates 102 from directly contacting each other, and at the same time ensure the balance of the two clamping plates 102, thereby better clamping and fixing the waterstop body 101.

[0034] The plurality of limiting members are symmetrically arranged in pairs on both sides of the clamp plate 102, and the plurality of limiting members are also inserted into the corresponding straightening plate 109 and located within the straightening plate 109.

[0035] Secondly, the spring 202 is welded to the pulling block 204 and located below the pulling block 204. The spring 202 is also welded to the corresponding clamp plate 102 and located on one side of the clamp plate 102. The spring 202 is sleeved on the limiting rod 203. The limiting rod 203 is inserted into the corresponding straightening plate 109 and located inside the straightening plate 109, and also passes through the corresponding clamp plate 102. By pulling the pulling block 204, the limiting rod 203 is pulled out of the slot 111. At this time, the straightening plate 109 is put into the slot 111. Finally, the pulling block 204 is released. Under the action of the pulling block 204 and the spring 202, the limiting rod 203 is inserted into the straightening plate 109 for initial fixation, which facilitates the subsequent installation of the bolt 108.

[0036] Using a waterstop positioning and straightening clamp according to this embodiment, the abutment ring 201 facilitates the two clamping plates 102 to avoid direct contact, while also ensuring the balance of the two clamping plates 102. This allows for better clamping and fixing of the waterstop body 101. Pulling the pulling block 204 causes the limiting rod 203 to be pulled out of the slot 111. Then, the straightening plate 109 is placed into the slot 111. Finally, the pulling block 204 is released, and the limiting rod 203, under the action of the pulling block 204 and the spring 202, initially fixes the straightening plate 109, thus facilitating the subsequent installation of the bolt 108.

[0037] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
