Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a tool for preventing welding slag from damaging pre-laid reverse-adhesive waterproof membrane. Background Technology

[0002] In construction engineering, raft foundations are often constructed using pre-laid reverse-adhesive polymer waterproof membranes. This is a common construction method. However, during the construction of steel reinforcement on the raft foundation, welding work is carried out on lightning protection, grounding, reinforcement bars, and galvanized steel pipes for wiring. Since there is no concrete protective layer after the pre-laid reverse-adhesive waterproof membrane is completed, welding slag will fall directly onto the surface of the waterproof membrane during the welding work, resulting in large-area damage to the waterproof membrane.

[0003] The vertical distance between the reinforcing bars on the raft slab and the waterproof membrane is typically 70cm, and approximately 140cm in the elevator shaft area. The raft slab reinforcing bars are double-layered and bidirectional, with a typical mesh size of 20cm x 20cm. In some areas with denser reinforcement, the mesh size is 5cm x 5cm. Due to the small mesh size, collection tools shaped like basins, sieves, or funnels are generally too large and made of rigid materials to be easily reshaped. This makes it impossible to install and fix these tools through the mesh in the denser areas for use during welding. Furthermore, the high spacing between the upper and lower layers of reinforcing bars means that if collection tools are placed on the lower layers before the upper layers are installed to collect welding slag, the tools and slag will be impossible to remove after the reinforcement work is completed.

[0004] Currently, when welding is performed on the raft foundation, water is sprayed underneath the welding area to prevent the welding slag from damaging the waterproof membrane. However, the welding slag temperature is too high, and this method cannot completely guarantee that the waterproof membrane will not be damaged. This ultimately leads to potential leaks in the basement, and the welding slag cannot be removed, causing slag inclusions in the concrete after pouring, which seriously affects the quality of the raft foundation concrete. Utility Model Content

[0005] This utility model provides a tool to prevent welding slag from damaging pre-laid reverse-adhesive waterproof membrane, which has the technical effect of preventing welding slag from damaging the waterproof membrane.

[0006] On the one hand, this utility model provides a tool to prevent welding slag from damaging pre-laid reverse-adhesive waterproof membrane, adopting the following technical solution:

[0007] A tool for preventing welding slag from damaging pre-laid reverse-adhesive waterproof membrane includes a fireproof cloth above the waterproof membrane, a raft foundation under steel reinforcement mesh above the waterproof membrane, the fireproof cloth above the raft foundation under steel reinforcement mesh, a raft foundation under steel reinforcement mesh above the fireproof cloth, hooks connected to the four corners of the fireproof cloth, the hooks hooking onto the raft foundation under steel reinforcement mesh, and the fireproof cloth being directly below the welding operation, with water sprayed onto the surface of the fireproof cloth.

[0008] Furthermore, the hook is an S-shaped hook.

[0009] Compared with the prior art, the present invention has the following technical effects:

[0010] 1. It directly prevents welding slag from contacting the waterproof membrane, thus protecting the membrane and reducing the risk of basement leaks. 2. It allows for easy collection and removal of welding slag, preventing it from forming slag inclusions in the concrete after pouring and improving the overall quality of the concrete. 3. The material size can be selected according to the construction environment. When the welding area is large, the fireproof cloth can be extended in all four directions to increase the coverage area. S-shaped hooks at each of the four corners ensure stability during use. 4. It can be installed in locations with rebar mesh of different sizes. Because the material is flexible, its shape can be changed according to the site conditions, completely unaffected by the size of the rebar mesh or the construction environment, avoiding installation or removal difficulties due to small mesh sizes. 5. This method is simple to construct, uses readily available materials, is easy to make, has low cost, and is reusable. 6. It speeds up construction progress, saves manpower, and avoids unnecessary losses from later repairs. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and descriptions of this utility model are used to explain the present utility model, but are not intended to limit the present utility model.

[0016] A tool for preventing welding slag from damaging pre-laid reverse-adhesive waterproof membrane includes a fireproof cloth 2, with hooks 1 fixedly connected to each of the four corners of the fireproof cloth 2. The hooks 1 are S-shaped hooks. The waterproof membrane 5 is located below the steel mesh 4 under the raft foundation, and the fireproof cloth 2 is located between the steel mesh 4 under the raft foundation and the steel mesh 3 on the raft foundation.

[0017] The size of the fireproof cloth 2 should be selected according to the scope of each welding operation. The mesh size of the reinforcing steel is usually 20cm*20cm, but for safety, the size of the fireproof cloth 22 can be increased to 40cm*40cm. If the welding area is large, a larger fireproof cloth 2 can be selected to increase the coverage area.

[0018] When encountering areas with denser rebar, where the mesh size is typically 5cm x 5cm, the fireproof cloth 2 and hook 1 can be rolled into a ball or thin strip for easy installation and disassembly.

[0019] Hook 1 is attached to the steel mesh 3 on the raft slab surrounding the welding operation area, causing the fireproof cloth 2 to hang directly below the welding operation. Water is poured onto the surface of the fireproof cloth 2 to keep it moist before the welding operation is carried out.

[0020] The working principle of this utility model for a tool to prevent welding slag from damaging pre-laid reverse-adhesive waterproof membrane is as follows:

[0021] S1. Before welding lightning protection, grounding, reinforcement bars, and galvanized steel pipes on the steel reinforcement bars on the raft slab, select the size of fireproof cloth 2 according to the scope of each welding operation. The mesh size of the steel reinforcement is usually 20cm*20cm. For safety, the size of fireproof cloth 2 can be increased to 40cm*40cm.

[0022] S2. Using hook 1, connect one end of the S-shaped hook 1 to the four corners of the fireproof cloth 2 to form a whole;

[0023] S3. Before the welding operation, hang the end of the hook 1 away from the fireproof cloth 2 on the steel mesh 3 of the raft plate around the welding operation, so that the entire fireproof cloth 2 is in a hanging state directly below the welding operation.

[0024] S4. Water is poured on the surface of the fireproof cloth 2 to keep it moist before welding can be carried out directly above it, so that the welding slag falls onto the surface of the fireproof cloth 2, thereby protecting the waterproof membrane 5.

[0025] S5. After the welding operation, the fireproof cloth 2 is removed from the steel mesh 3 on the raft slab to remove the welding slag.

[0026] S6 and fireproof cloth 2 are reused for the next welding operation.

[0027] The advantages of this utility model compared with the prior art are as follows: 1. It can directly prevent welding slag from contacting the waterproof membrane 5, thereby protecting the waterproof membrane 5 and reducing the risk of basement leakage. 2. It can collect and remove all welding slag, preventing the formation of concrete inclusions after concrete pouring and improving the quality of the concrete. 3. The material size can be selected according to the construction environment. When the welding construction area is large, the fireproof cloth 2 can be extended infinitely in four directions to increase the coverage area, and S-shaped hooks are provided at the four corners, making it very stable and not shaking during use. 4. It can be installed and used in steel mesh locations of different sizes. Because its material is flexible, its shape can be changed according to the on-site construction environment, completely unaffected by the size of the steel mesh and the construction environment, avoiding the inability to install or remove due to the mesh being too small. 5. This method is simple to construct, uses readily available materials, is easy to manufacture, has a low cost, and can be reused. 6. It speeds up the construction progress, saves manpower, and avoids unnecessary losses caused by later repairs.

[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the scope of protection of this utility model.
