Embodiment Construction
[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings, but not as any limitation to the present invention.
[0021] A kind of processing method of roof waterproof flashing closure of the present invention, such as figure 1 and figure 2 As shown, the method is to lay a waterproof layer 3 on the roof 1 with a waterproof coiled material during the roof waterproofing construction. Open a long groove with a width of 30-40mm and a depth of 20-30mm at a height of 600mm, and then cut the waterproof membrane at the groove 4, and fix the edge of the waterproof membrane on the bottom of the groove with nails or hot melt adhesive; Fill up the groove with ointment 5 again, and then construct a protective layer 6 on the surface of the waterproof coiled material. After the strength of the protective layer reaches the requirements, seal the groove with a groove seal 7. The waterproof layer 2 is directly pasted on the orig...

The invention discloses a sealing method and structure for roof waterproof flashing. The method comprises the steps that during roof waterproof construction, a waterproof layer (3) made of a waterproof roll is laid on a roof (1), the waterproof roll is upturned at the position where the roof and a parapet (2) are connected and continues to be attached to the parapet, and a full-length groove with the width ranging from 30 mm to 40 mm and the depth ranging from 20 mm to 30 mm is formed at the position, 600 mm away from the roof, of the parapet; the waterproof roll is cut off at the position of the groove (4), and the edge of the waterproof roll is fixed to the bottom face of the groove with fasteners or hot melt adhesive; the groove is filled with grease (5); a protective layer (6) is constructed on the surface of the waterproof roll, after the protective layer meets the strength requirement, and the groove is sealed through groove strip seal (7). According to the sealing method and structure for roof waterproof flashing, multiple waterproof measures are taken to seal the flashing, the input cost is low, the problem of leakage of roof flashing can be solved in a one-off mode, the appearance is attractive, the waterproof effect is excellent, the excellence creating condition is provided, and a good foundation is laid for engineer excellence creation.
Description
technical field [0001] The invention relates to a treatment method and structure of a roof waterproof flashing closure, belonging to the technical field of roof waterproofing in construction projects. Background technique [0002] With the current popularization of high-rise buildings, the roof waterproof level is generally high. For high-rise buildings with high roof design waterproof level, the quality of roof construction is very important. There are many procedures and high requirements for roof flooding, and it is the part where more common quality problems occur. Especially the roof flashing closing part is the key part of the roofing project. In the current project example, the ointment caulking is simply used for sealing. Due to the thermal expansion and cold contraction of the ointment, it is very easy to have a hidden danger of leakage at the flashing closing part, which seriously affects the later use. And the scope of this method construction, construction is a...
