As for whether the overlap between the coiled material and the coiled material is effective, the domestic coiled material product standard generally adopts the "test method of seam peel strength" (asphalt waterproof membrane see GB 18242-2008 "Elastomer Modified Bitumen Waterproofing "Coiled Material" and other standards, see GB 12952-2011 "Polyvinyl Chloride (PVC) Waterproof Membrane" for polymer waterproof membranes), this method can only reflect the adhesive performance of the lap joints of the coils, but cannot reflect the lap joints water penetration resistance

Embodiment Construction
[0025] In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be interpreted as indicating or implying relative importance or implicitly specifying the quantity of indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include at least one of these features. In the description of the present application, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.
[0026] In this application, terms such as "installation", "connection", "connection" and "fixation" should be interpreted in a broad sense, for example, it can be a fixed connection or a detachable connection, unless otherwise clearly specified and limited. , or integrated; it may be mechanically connected or electrically connected; it may be directly connected or indirectly connected through an intermediary, and it may be the internal communication of two components or the interactio...

Abstract
The invention relates to a method for detecting watertightness of the seam of a waterproof roll. The method comprises the following steps of: S1, manufacturing a sample; S2, mounting the sample; and S3, detecting the sample. According to the invention, on the premise that the waterproof performance of a lap seam can be detected, the lap seam is covered by a slot driller, and the pressure is further concentrated to the seam corresponding to the slot driller, so that the pressure on a roll at the lap seam to be detected is uniform, and the accuracy of the detection result is improved; and meanwhile, a sample with the height difference after lap joint eliminated is formed, an anti-sinking bracket or a cushion block is used for supporting, so that a test piece is flatly positioned, and the accuracy of the detection result is further improved.
Description
technical field [0001] The invention belongs to the field of detection of waterproof coiled materials, and in particular relates to a method for detecting the water impermeability of seams of waterproof coiled materials. Background technique [0002] As we all know, waterproof membranes are different from waterproof coatings. In actual use, a complete waterproof layer can be formed on a plane by lapping one by one between the membranes and the membranes, thereby protecting the main body of the building from external water. . [0003] Then, the overlapping parts of the coiled material and the coiled material are also the parts with high incidence of leakage. As for whether the overlap between the coiled material and the coiled material is effective, the domestic coiled material product standard generally adopts the "test method of seam peel strength" (asphalt waterproof membrane see GB 18242-2008 "Elastomer Modified Bitumen Waterproofing "Coiled Material" and other standard...
