Abstract
Description
Technical Field
[0001] This utility model relates to the field of waterstop laying technology, and more specifically, to a waterstop laying device. Background Technology
[0002] In building engineering, especially underground structures, hydraulic structures and tunnel engineering, waterstops are one of the key materials to prevent water penetration. Their function is to seal structural joints and ensure the waterproof performance of the structure. Back-adhesive waterstops are widely used because they are easy to construct and have high bonding strength.
[0003] However, in actual construction, the installation of waterstops often faces technical challenges: the problem of delamination caused by poor adhesion between the waterstop and the waterproof membrane during installation. This may be due to insufficient cleanliness of the concrete surface, excessive humidity, or uneven pressure during adhesion, affecting the overall waterproofing effect of the project. Therefore, we have made improvements and proposed a waterstop installation device. Utility Model Content

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0024] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0026] Example 1, please refer to Figures 1-4 A waterstop laying device includes a first threaded pipe 1, a fixing structure 2 on the first threaded pipe 1, the fixing structure 2 being used to fix the first threaded pipe 1 to a steel bar or column near the waterstop, a threaded rod 101 being threadedly connected to the inner wall of the first threaded pipe 1, a pressure plate 102 being provided at one end of the threaded rod 101, the pressure plate 102 being used to press the waterstop under the action of the threaded rod 101 and the first threaded pipe 1;
[0027] This application uses a fixing structure 2 to fix the first threaded pipe 1 to a steel bar or column near the waterstop, thereby fixing the first threaded pipe 1. The threaded rod 101, the first threaded pipe 1, and the pressure plate 102 work together to press down on the waterstop during the laying process, so that the back-adhesive waterstop and the waterproof membrane are effectively and tightly bonded, making it less prone to delamination, thus ensuring the laying quality of the waterstop.
[0028] Example 2 further optimizes the waterstop laying device provided in Example 1. Specifically, one end of the threaded rod 101 is rotatably connected to the pressure plate 102 through a bearing. This arrangement allows the pressure plate 102 and the threaded rod 101 to rotate, thereby enabling the horizontal and vertical adjustment of the pressure plate 102.
[0029] Example 3 further optimizes the waterstop laying device provided in Example 1. Specifically, one end of the threaded rod 101 is fixedly connected to the pressure plate 102, and the fixed connection has high strength and good stability.
[0030] Example 4 further optimizes the waterstop laying device provided in the above embodiments. Specifically, a first nut 103 is fixedly sleeved on the outer surface of the threaded rod 101, and the side of the first nut 103 contacts the pressure plate 102; a second nut 104 is fixedly sleeved on the outer surface of the first threaded tube 1 near the pressure plate 102; the first nut 103 is used to cooperate with a wrench to rotate the threaded rod 101, and the second nut 104 is used to cooperate with a wrench to fix the first threaded tube 1 during the rotation of the threaded rod 101. That is, two wrenches are used, one wrench holds the second nut 104 and does not rotate, while the other wrench rotates the first nut 103 to drive the threaded rod 101 to rotate. When the threaded rod 101 rotates, the pressure plate 102 moves closer to or away from the first threaded tube 1.
[0031] Furthermore, there are two fixing structures 2, which cooperate with each other to clamp onto the steel bars or columns near the waterstop, thereby fixing the first threaded pipe 1. The distance between the two fixing structures 2 and the position of the two fixing structures 2 can be adjusted to improve the applicability of this application.
[0032] Furthermore, the fixing structure 2 includes a second threaded tube 201 threadedly connected to the outer surface of the first threaded tube 1. A clamping plate 203 is rotatably sleeved on the outer surface of the second threaded tube 201. The threaded connection between the second threaded tube 201 and the first threaded tube 1 allows the second threaded tube 201 to move on the first threaded tube 1 when it rotates.
[0033] Furthermore, the inner side of the clamping plate 203 is provided with a slot 204. The slot 204 is designed to facilitate engagement with the shape of the reinforcing bar and the circular column to improve stability during fixing.
[0034] Furthermore, two third nuts 202 are fixedly sleeved on the outer surface of the second threaded tube 201. The two third nuts 202 are located on both sides of the clamping plate 203. The setting of the third nuts 202 makes it convenient to rotate the second threaded tube 201 with a wrench.
[0035] The process of using the waterstop laying device provided by this utility model is as follows:
[0036] For ease of understanding, this application uses A to represent the reinforcing bar or column near the waterstop. In use, a wrench is used to rotate the second threaded tube 201 through the third nut 202 to adjust the position of the second threaded tube 201 on the first threaded tube 1 and the distance between the two second threaded tubes 201 according to the actual situation. The two clamping plates 203 are placed on both sides of the reinforcing bar or column near the waterstop. Then, the third nut 202 is rotated to make the second threaded tube 201 rotate so that the clamping plates 203 move toward the reinforcing bar or column and clamp onto the reinforcing bar or column. Two wrenches are used. One wrench holds the second nut 104 and does not rotate, while the other wrench rotates the first nut 103 to drive the threaded rod 101 to rotate. When the threaded rod 101 rotates, the pressure plate 102 moves toward the waterstop to press the waterstop against the waterproof board.
