Description

When the two waterproof coiled materials are connected, the other waterproof coiled material is inserted into the lower accommodating cavity from the right end of the third connecting component 3 to form the lower waterproof coiled material 5 at the connection position of the two waterproof coiled materials. In the whole edge sealing connection structure formed by the first connecting component 1, the second connecting component 2 and the third connecting component 3 after splicing, the two waterproof coiled materials are arranged in the middle accommodating cavity of the second connecting component 2 in an up-down manner. The first middle plate 13 of the first connecting component 1 extends into the second connecting component 2 and abuts against the left end of the second middle plate 23 of the second connecting component 2.

[0064] When the two waterproof coiled materials are connected, one of the waterproof coiled materials is inserted from the left end of the first connecting component 1 into the upper accommodating cavity to form the upper waterproof coiled material 4 at the connection of the two waterproof coiled materials. The other waterproof coiled material is inserted from the right end of the third connecting component 3 into the lower accommodating cavity to form the lower waterproof coiled material 5 at the connection of the two waterproof coiled materials.

[0065] In the whole sealing edge connecting structure formed by the first connecting component 1, the second connecting component 2 and the third connecting component 3 after splicing, the two waterproof coiled materials are distributed in the middle accommodating cavity of the second connecting component 2, the first middle plate 13 of the first connecting component 1 extends into the second connecting component 2, and the left end of the second middle plate 23 of the second connecting component 2 abuts against, at this time, the upper waterproof coiled material 4 is located above the first middle plate 13, below the first upper plate 12 and the second upper plate 22, the lower waterproof coiled material 5 is located below the first middle plate 13, the second middle plate 23 and the third middle plate 33, and above the second lower plate 24 and the third lower plate 34, thereby forming the waterproof coiled material sealing edge connecting structure in which the upper waterproof coiled material 4 and the lower waterproof coiled material 5 are overlapped and arranged, and further ensuring the waterproof effect at the connecting position of the two waterproof coiled materials.
