Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of waterproof coiled materials, in particular to an SBS modified asphalt waterproof coiled material. Background Art
[0002] SBS modified asphalt waterproofing membrane is made of polymer SBS modified asphalt as the main component, mixed with fillers, reinforcing materials, etc. It is commonly used as waterproofing material for building roofs, basements, tunnels and other projects.
[0003] The joint treatment of waterproof membranes is a very critical link in waterproofing projects. When using waterproof membranes, two or more groups of membranes are generally spliced together to achieve the purpose of adapting to the scene, and then the adjacent membranes are melted and compacted by hot melting to achieve the purpose of joint treatment. However, when the membranes are hot melted, some smoke such as carbon monoxide and sulfur dioxide will be produced. These gases are harmful to human health. Construction workers exposed to these gases for a long time will cause dizziness, nausea, eye irritation and other symptoms, and in severe cases will affect the heart and respiratory system functions; and when the membranes are laid on the roof of a bungalow, they will be exposed to direct ultraviolet rays. Long-term ultraviolet exposure will accelerate the aging of the material, resulting in cracks, hardening, color changes and other phenomena on the surface of the membrane, reducing the service life of the membrane.
[0004] In summary, the current SBS modified asphalt waterproofing membrane still has the following defects during use:
[0005] (1) Using hot melt to splice the coiled materials will have an impact on the health of the construction workers;
[0006] (2) Direct ultraviolet rays will reduce the service life of the coil. Utility Model Content

Example 1
[0033] Reference Figure 1-4 , which is the first embodiment of the utility model, provides an SBS modified asphalt waterproofing membrane, the SBS modified asphalt waterproofing membrane comprises a membrane body 1, connecting pieces are installed on both sides of the membrane body 1, and a protective piece is arranged inside the membrane body 1;
[0034] The connecting piece includes a connecting block A2 fixed at one end of the coil body 1, a clamping block A3 is fixedly connected to one end of the coil body 1 and located on one side of the connecting block A2, a clamping block B5 is fixedly connected to the other end of the coil body 1 and away from the connecting block A2, and a connecting block B7 is fixedly connected to the other end of the coil body 1 and located on one side of the clamping block B5. The clamping blocks A3, B5, connecting blocks A2 and connecting blocks B7 can connect two or more groups of coil bodies 1, thereby solving the joint problem, and the operation is simple and can prevent smoke from causing physical harm to construction workers.
[0035] Glue layers 4 are installed on the inner side of the connecting block A2 and on both sides of the card block A3. The connecting block A2 is rectangular and the card block A3 is trapezoidal. One side of the connecting block A2 is horizontally consistent with the side surface of the coil body 1, so that there will be no difference in the use of the coil body 1. The trapezoidal card block A3 can be connected with the card block B5.
[0036] Scraper strips 6 are installed on the inner side of the connecting block B7 and on both sides of the clamping block B5. The connecting block B7 is rectangular, and the clamping block B5 and the scraper strip 6 are both trapezoidal. One side of the connecting block B7 is horizontally consistent with the side of the coil body 1, which can prevent the coil body 1 from being laid inconsistently during laying. The clamping block B5 is clamped with the clamping block A3, and the scraper strip 6 is located on one side of the glue layer 4. The trapezoidal scraper strip 6 can scratch the glue layer 4 to make the glue inside the glue layer 4 overflow to achieve the purpose of adhesion.
[0037] The clamping blocks A3 and the clamping blocks B5 are arranged equidistantly and are clamped together. The clamping of the clamping blocks A3 and B5 can make it more convenient to connect two or more groups of coil bodies 1.
[0038] During use, one group of coil body 1 is laid, and then the block B5 on one side of the coil body 1 of the second group is inserted into the gap in the block A3 on one side of the coil body 1 of the first group, so that the block B5 is connected with the block A3. At the same time, when the block B5 moves to the inside of the block A3, the scraper strips 6 on both sides of the block B5 and the scraper strips 6 inside the connecting block B7 will contact the glue layer 4 on the inner side of the block A3 and the connecting block A2, and because the scraper strips 6 are trapezoidal, they will scratch the glue layer 4 while contacting the glue layer 4, and the glue inside will slowly overflow until the block B5 and the connecting block B7 are firmly adhered to complete the splicing operation. When performing multiple groups of splicing, just repeat the above operation. This method is simple and easy to use, and solves the problem of using hot melt method to splice the coil body 1, which will produce smoke and cause physical harm to construction workers. Example 2
