Description
Technical Field
[0001] The present application relates to the technical field of waterproofing for construction projects, and in particular to a construction process for terminating a waterproofing coil at a water dispersion location and a waterproofing structure. Background Art
[0002] Waterproof membranes are mainly used in building roofs, basements, walls, balconies, bathrooms and other parts that require waterproofing. They are the first barrier to waterproofing the entire construction project. Their function is to form a continuous waterproof barrier to prevent moisture penetration, protect the building structure from moisture and water damage, extend the service life of the building, and provide a dry and comfortable environment for residents.
[0003] In the related art, there are generally two ways to finish the basement waterproofing membrane at the location of the water dispersion. One is that when the main structure concrete of the first floor is constructed, the non-removal insulation integrated board is laid upward from the first floor elevation -100mm. When the basement is subsequently waterproofed, the non-removal insulation integrated board at the first floor elevation -100 to +200mm is cut, and then the waterproofing membrane is laid inside and fixed to the wall with cement nails, and finally the non-removal insulation integrated board is re-laid. Another way is that when the main structure concrete of the first floor is constructed, the non-removal insulation integrated board is laid upward from the first floor elevation +200mm. The first floor elevation -100 to +200mm is supported by formwork. After the subsequent formwork is demolded, the waterproofing membrane is laid inside and fixed to the wall with cement nails, and finally the non-removal insulation integrated board is re-laid.
[0004] With regard to the above-mentioned related technologies, leakage is easily generated at the edges where the waterproof membrane abuts against the wall or at the places where the waterproof membrane is penetrated by cement nails, thereby reducing the waterproof performance of the waterproof membrane.

Use a broom, brush or other tools to thoroughly remove the dust and debris on the inner side of the non-disassembly insulation integrated panel 3 to ensure that the surface is clean, flat and free of impurities. If there is moisture on the surface, wait for it to dry naturally or use drying equipment to dry it to ensure that the surface is dry before construction.

The coating thickness is about 0.5 to 1 mm, and the coating height is 485 mm above the root of the non-disassembly thermal insulation integrated panel 3.
[0034] The adhesive in step 2 may also be cement mortar, and the brushing height of the adhesive may be adjusted according to the height at which the waterproof membrane 1 needs to be laid.
[0035] Step three, lay the waterproof membrane 1 from 500mm above the root of the non-disassembly insulation integrated panel 3 downward on the inner side of the non-disassembly insulation integrated panel 3, so that a 15mm unbonded part is reserved at the top of the waterproof membrane 1, and the other end of the waterproof membrane 1 extends 1000-1500mm out of the root of the non-disassembly insulation integrated panel 3, so as to facilitate the subsequent connection with the outer waterproof membrane laid after the main structure 100; the waterproof membrane 1 uses SBS waterproof membrane with a width of 1200mm. When laying the waterproof membrane 1, it is slowly laid to the entire inner side of the non-disassembly insulation integrated panel 3, and a special roller is used to roll the waterproof membrane 1 along the edge and middle of the waterproof membrane 1 for multiple times to ensure that the waterproof membrane 1 is fully bonded to the inner side of the non-disassembly insulation integrated panel 3 without bubbles inside; overlap adjacent waterproof membranes 1, the width of the overlap joint is not less than 100mm, and the overlap joints are flame-baked and welded with adjacent waterproof membranes 1.
[0036] The waterproof membrane 1 in step 3 can be TPZ waterproof membrane, and adjacent membranes are bonded with cement mortar. The unbonded portion reserved at the top of the waterproof membrane 1 can also be 10 mm or 20 mm.

One end of the top form rod 5 is in contact with the waterproof membrane 1, and the other end is in contact with the formwork 4.
