[0019] The utility model embodiment provides a non-perforated waterproof coiled material fixing structure, such as Figure 1-3 As shown, it includes a base layer 1, a vapor barrier layer 2, a thermal insulation layer 3, a roll waterproof layer 4 and a screw 6. The vapor barrier layer 2 is fixedly mounted on the outer surface of the base layer 1, the thermal insulation layer 3 is fixedly bonded to the outer surface of the vapor barrier layer 2, and the tail end of the screw 6 pierces the thermal insulation layer 3 and the vapor barrier layer 2 from the outside to the inside in sequence, and is screwed into the base layer 1. The roll waterproof layer 4 is fixedly bonded to the outside of the thermal insulation layer 3, and the roll waterproof layer 4 is used to cover the screw 6.

[0020] It also includes a nail sleeve 7, which is pre-buried in the vapor isolation layer 2. The screw 6 passes through the nail sleeve 7. A rubber layer 72 is fixedly installed on the inner wall of the nail sleeve 7. The rubber layer 72 surrounds it in a circle. The shaft of the screw 6 is provided with a raised portion 61. The screw 6 and the raised portion 61 are integrally formed. The raised portion 61 enters the nail sleeve 7 to squeeze the rubber layer 72.

[0021] A plurality of pricking needles 71 are provided at the bottom of the nail sleeve 7, and the nail sleeve 7 and the pricking needles 71 are integrally formed. The plurality of pricking needles 71 are arranged at equal distances, and the lower ends of the pricking needles 71 pierce into the base layer 1.

[0022] The thermal insulation layer 3 is composed of rock wool, which has the advantages of light weight, low thermal conductivity, good elasticity, non-flammability, no moth-eaten, no rot, good chemical stability, and also has excellent sound insulation performance.

[0023] When the tail end of the screw 6 penetrates into the base layer 1 , a depression 41 is generated. A gasket 5 is placed in the depression 41 . The shaft of the screw 6 passes through the gasket 5 , and the head end of the screw 6 contacts the gasket 5 .

[0024] The inner diameter of the nail sleeve 7 gradually decreases from top to bottom, so as to prevent the raised area of ​​the screw 6 from escaping from the nail sleeve 7.

[0025] When the raised portion 61 enters the rubber layer 2 , the closer it is to the lower end of the needle sleeve 6 , the more difficult it is for the screw 6 to go deeper.

[0026] In summary, the non-perforated waterproof coiled material fixing structure is composed of a base layer 1, a vapor barrier layer 2, a thermal insulation layer 3, and a coiled material waterproof layer 4. The screw 6 penetrates the vapor barrier layer 2 and the thermal insulation layer 3 and is inserted into the base layer 1, and then passes through the coiled material waterproof layer to cover the screw 6, so as to achieve the purpose of hiding the screw 6 and make the screw 6 embedded in the entire waterproof coiled material. A needle cover 7 is provided, which cooperates with the rubber layer 72 and the raised portion 61 to play a role of obstruction and reminder, thereby avoiding multiple perforations during the installation of the waterproof coiled material. The screw 6 is prevented from continuing to penetrate the waterproof coiled material, and when the screw 6 has difficulty in penetrating, it reminds the user that the screw has reached the said depth. Avoid piercing the waterproof coiled material.
