Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of construction engineering, in particular to a T-shaped fin-shaped concrete construction wooden template leak-proof sealing strip. Background Art
[0002] During cast-in-place concrete construction in the construction industry, wooden formwork is often used to maintain the concrete's shape. During the concrete pouring process, concrete leakage is common with traditional wooden formwork during vibration compaction, impacting the quality of the finished concrete structure. Existing processes often use foam sponge strips to adhere to the joints between wooden formwork to prevent leakage. However, this is ineffective in preventing leakage in practice, and the strips are difficult to clean after use, resulting in wasted work time. Utility Model Content
[0003] The purpose of the utility model is to provide a T-shaped fin-shaped concrete construction wooden formwork leak-proof seal to solve the problems raised in the above background technology.
[0004] To achieve the above objectives, the present invention provides the following technical solutions:
[0005] A T-shaped fin-shaped concrete construction wood formwork leak-proof seal has a T-shaped structure and includes a seal body, a clamping strip and a fin-shaped fixing strip; the seal body is fixedly connected to the clamping strip, and the fin-shaped fixing strip is fixedly connected to the clamping strip; the seal body covers the connection gap of the wood formwork, and the clamping strip and the fin-shaped fixing strip fill the connection gap of the wood formwork.
[0006] As a further solution of the present invention: the sealing strip body, the clamping strip and the fin-shaped fixing strip are all made of flexible waterproof material.
[0007] Compared with the existing technology, the beneficial effects of the utility model are: preventing leakage of concrete between concrete wooden formworks, treating it from the source, and the entire gap is free of slurry; achieving the fixed and non-displacement of the leak-proof seal during concrete pouring; achieving the recyclable use of the leak-proof seal; achieving the machinability of the leak-proof seal, and achieving the ability to be cut to suit different formwork lengths.

[0013] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0014] See also Figure 1-4 The utility model provides a T-shaped fin-shaped leak-proof seal for wooden formwork for concrete construction, the structure of which includes a seal body 1, a clamping strip 2, and a fin-shaped fixing strip 3; the seal body 1 is fixedly connected to the clamping strip 2, and the fin-shaped fixing strip 3 is fixedly connected to the clamping strip 2. The seal body 1 covers the connection gap between the wooden formwork 4, and the clamping strip 2 and the fin-shaped fixing strip 3 fill the connection gap between the wooden formwork 4; the leak-proof seal is T-shaped. Preferably, the seal body 1 is made of a flexible waterproof material, such as rubber, and can be cut according to actual construction needs. The seal body 1 completely covers and fits tightly against the gap between the wooden formwork 4, and has a certain width to prevent the slurry from leaking along the gap between the wooden formwork 4 during concrete pouring operations.
[0015] Preferably, the clamping strip 2 is made of a flexible waterproof material, such as rubber, and can be cut according to actual construction needs.
[0016] Preferably, the fin-shaped fixing strip 3 is made of a flexible, waterproof material, such as rubber, and can be cut to fit the actual construction requirements. The fin-shaped fixing strip 3 has a high coefficient of friction with the wood material, and the compressed wood formwork 4 can cause the fin-shaped fixing strip 3 to deform, clinging to the gaps in the wood formwork 4. When the leak-proof seal is pulled, the fin-shaped fixing strip 3 generates friction to prevent the seal from falling off, thus securing the leak-proof seal. The deformed fin-shaped fixing strip 3 generates an inward pulling force, forcing the seal body 1 of the leak-proof seal to cling to the casting surface of the wood formwork 4.
[0017] Usage: This product is used to prevent concrete leakage from wooden formwork 4 during concrete pouring in construction projects. During the installation of the wooden formwork 4 for pouring concrete, after the first wooden formwork 4 is installed and fixed, the leak-proof seal is cut to the same length according to the height of the wooden formwork 4 and laid along the edge of the wooden formwork 4. The second formwork is then installed so that the gap between the two wooden formworks 4 is completely covered by the seal body 1. The gap between the two wooden formworks 4 is squeezed tightly, causing the fin-shaped fixing strips 3 to deform and cling to the edges of the wooden formworks 4 on both sides. The clamping strips 2 and the fin-shaped fixing strips 3 fill the gap between the wooden formworks 4. Simultaneously, the deformation of the fin-shaped fixing strips 3 causes the leak-proof seal to shift inward, and the seal body 1 clings to the concrete pouring surface of the adjacent wooden formworks 4, forming a smooth concrete pouring surface. Continue with the above steps to install all the wooden formworks 4 for pouring concrete. Before pouring concrete, if the leak-proof seal is affected by external tension or its own weight, which may cause it to fall off, the friction generated by the pressure on the fin-shaped fixing strips 3 can ensure the leak-proof seal is fixed. During the concrete pouring operation, the gaps between the wooden templates 4 are covered by the sealing strip body 1, thereby preventing the concrete slurry from leaking along the gaps.
[0018] The preferred embodiments of the present application are described in detail above, but the present application is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in this field without departing from the purpose of the present application.
