Technical Field

[0001] This utility model relates to the field of hydraulic structure construction technology, specifically to a centrally embedded rubber waterstop end fixing device. Background Technology

[0002] During the construction of hydraulic structures, the waterproof connection between construction joints is extremely important because they operate in water. The traditional connection method is to use steel bars for fixing (positioning bars) and wooden molds for fixing the formwork. However, when pouring concrete, the embedded rubber waterstop will move, affecting the construction quality and waterproofing quality. Utility Model Content

[0003] The purpose of this utility model is to provide a centrally embedded rubber waterstop end fixing device, which solves the positioning and fixing problems between the waterstop and the reinforcing bars and formwork, improves construction efficiency, and further solves the leakage phenomenon between construction joints.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a device for fixing the end of an embedded rubber waterstop, comprising an L-shaped steel template and a fixing clamp. One end of the L-shaped steel template is fixed to the rubber waterstop, and the other end of the L-shaped steel template is connected to a template. The connection between the L-shaped steel template and the rubber waterstop is L-shaped, and the two L-shaped steel templates clamp and fix the embedded rubber waterstop. After fixing, the end of the L-shaped steel template is further reinforced by the fixing clamp. The contact position between the fixing clamp and the L-shaped steel template has a pre-drilled long screw hole, and the clamp is fixedly connected to the L-shaped steel template by a long screw and a nut for clamping the rubber waterstop.

[0005] Preferably, the L-shaped steel formwork is 1.2m long and 0.45m wide, and can be adjusted according to the width of the building. Reinforcing ribs are provided on the side of the L-shaped steel formwork.

[0018] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5This embodiment provides a recessed rubber waterstop end fixing device, including an L-shaped steel template 1 and a fixing clamp 2. The L-shaped steel template 1 is 1.2m long and 0.45m wide, and can be adjusted according to the width of the building. Reinforcing ribs 6 are provided on the side of the L-shaped steel template 1. One end of the L-shaped steel template 1 is fixed to the rubber waterstop 3. Tie rods 7 are provided at the front and rear of the rubber waterstop 3, and a waterstop plate 8 is provided in the middle of the tie rods 7. The other end of the L-shaped steel template 1 is connected to a template 4, which can be a wooden or steel template. When the L-shaped steel template 1 is connected to the wooden template, the end is extended outward by 2cm, increasing the length by 10cm. The wooden template is embedded 110cm into the L-shaped steel template 1 to enhance the connection effect. The connection between the template 1 and the rubber waterstop 3 is set in an L-shape. Two L-shaped steel templates 1 clamp and fix the embedded rubber waterstop 3. The rubber waterstop 3 is bent at 90°. After fixing, the end of the L-shaped steel template 1 is further reinforced by the fixing clamp 2. The fixing clamp 2 is U-shaped with dimensions of 0.55m long * 0.36m wide * 0.05m thick. The contact position between the fixing clamp 2 and the L-shaped steel template 1 is reserved with long screw holes, and is fixedly connected to the L-shaped steel template 1 by long screws 5 and nuts to clamp the rubber waterstop 3 and prevent movement. A tie rod 7 is reserved in the middle position of the fixing clamp 2, and forms a two-way force structure with the tie rod 7 on the L-shaped steel template 1.

[0020] In practical use, firstly, L-shaped steel formwork 1 is customized according to the width of the wall and the width of the rubber waterstop 3. The dimensions of this L-shaped steel formwork 1 are generally 1.2m long and 0.45m wide, and it is equipped with reinforcing ribs 6 to improve overall rigidity. One end of the L-shaped steel formwork 1 is fixed to the rubber waterstop 3, and the other end is connected to the formwork 4, as follows. Figure 2 As shown; subsequently, L-shaped steel formwork 1 is installed starting 1.2m from the end of the rubber waterstop 3. Wooden or steel formwork can be installed beyond 1.2m, depending on the actual situation. After installing the L-shaped steel formwork 1, the rubber waterstop 3 is clamped. Long screws 5, pre-drilled holes, and matching nuts are installed inside the fixing clamp 2. Tie rods 7 are also installed inside the fixing clamp 2 for reinforcement, as shown below. Figure 3 As shown.

[0021] Unlike traditional rubber waterstops 3, which rely on positioning ribs and formwork for fixation and are prone to movement and damage during concrete pouring or other construction, this device utilizes L-shaped steel formwork 1 and fixing clamps 2 to greatly improve construction efficiency and quality while significantly reducing construction costs. Calculations show that traditional fixing methods require manual fabrication of positioning ribs, wooden formwork, and filling gaps with expanding foam, costing approximately 1200 yuan per end of the rubber waterstop 3. Using this device requires a one-time investment of approximately 2000 yuan and can be used to install all the rubber waterstops 3 in this project. When the number of waterstops in a project exceeds two, this device can be customized for installation.

[0022] In summary, this utility model solves the problems in the construction of rubber waterstops, completes the construction task quickly, safely, and with high quality, saves construction costs, further improves the quality of waterstop construction, greatly reduces the quality problems of pile head breaking, improves the stability and anti-leakage quality of rubber waterstops, and accelerates the construction progress.
