DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0028] Embodiment 1:

[0029] See also Figure 1-8 The present invention provides a technical solution: a roof waterproof layer anti-cracking structure and a use method, comprising a protective net 1 and a connecting net 2, a connecting mechanism is arranged between the protective net 1 and the connecting net 2, the connecting mechanism is used to connect adjacent protective nets 1 through the connecting net 2, anchor rods 7 are arranged in an evenly spaced array on the upper side of the protective net 1 and the connecting net 2, and positioning cones 8 are arranged in an evenly spaced array on the lower side of the protective net 1 and the connecting net 2, the anchor rods 7 are anchored in the cement slurry of the upper layer, and the positioning cones 8 are inserted into the asphalt waterproof layer of the lower layer.

[0030] In this way, in the specific construction of the waterproof layer, a waterproof membrane layer 103 can be laid on the roof first. The waterproof membrane can specifically be a modified asphalt waterproof membrane. Then, a protective net 1 and a connecting net 2 are laid on the top of the waterproof membrane layer to form a protective net layer 102. Since the lower end surfaces of the protective net 1 and the connecting net 2 are connected with positioning cones 8 in an array, the waterproof membrane layer 103 below can be pierced by the positioning cones 8, so that the waterproof membrane layer 103 can be fastened and fixed in place, thereby effectively avoiding cracking of the waterproof membrane layer 103 during subsequent use.

[0031] By setting the anchor rod 7, after the protective mesh layer 102 is laid, when the cement slurry layer 101 is laid, the anchor rod 7 can be embedded in the cement slurry layer 101, thereby forming a stable connection relationship between the cement slurry layer 101, the protective mesh layer 102 and the waterproof membrane layer 103, thereby improving stability and avoiding cracking after long-term use, thereby reducing the waterproof effect.

[0032] However, it is necessary to ensure that the length of the positioning cone 8 is limited so that when the positioning cone 8 punctures the upper surface of the waterproof membrane layer 103 , the puncture depth does not exceed 1 / 4 of the thickness of the waterproof membrane layer 103 .

[0033] The connecting mechanism includes protective net edge strips 3 and connecting net edge strips 4. The protective net edge strips 3 are arranged at equal intervals on the sides of the protective net 1, and the connecting net edge strips 4 are arranged at equal intervals on the sides of the connecting net 2. The protective net edge strips 3 and the connecting net edge strips 4 are arranged correspondingly, and the protective net edge strips 3 are arranged above the connecting net edge strips 4.

[0034] When constructing the protective net layer 102, multiple pieces of protective nets 1 are laid, and adjacent protective nets 1 are connected by connecting nets 2. Specifically, the protective net edge strips 3 on the protective net 1 are aligned with the connecting net edge strips 4 on the connecting net 2. The protective net 1, the connecting net 2, the protective net edge strips 3, and the connecting net edge strips 4 can all be made of PV material, which makes it convenient to bind and connect them through rivets, or to perform hot-melt connection through a hot-melt machine.

[0035] Cement slurry circulation holes 9 are opened on the edge strips of the protective net 1 and the connecting net 2, so that when the cement slurry layer 101 is constructed, the cement slurry can be densely filled in various places of the waterproof net layer 102 through the cement slurry circulation holes 9, thereby ensuring the effect of cement slurry laying and filling.

[0036] Embodiment 2:

[0037] See also Figure 1-8The present invention provides a technical solution: the connecting mechanism also includes a bolt hole 5, a countersunk hole 6, a bolt 10, and a nut 11. The bolt hole 5 is opened on the protective net side strip 3 and the connecting net side strip 4. The countersunk hole 6 is opened at the upper end of the bolt hole 5 on the protective net side strip 3 or the lower end of the bolt hole 5 on the connecting net side strip 4. A bolt 10 is installed between the bolt hole 5 on the protective net side strip 3 and the bolt hole 5 on the connecting net side strip 4. The upper end of the bolt 10 is threadedly connected with a nut 11, and the lower end of the bolt 10 and the nut 11 are correspondingly arranged in the countersunk hole 6.

[0038] When constructing the protective net layer 102, the connection between the protective net 1 and the connecting net 2 can also be achieved by aligning the protective net edge strip 3 on the protective net 1 with the connecting net edge strip 4 on the connecting net 2, and aligning the bolt holes 5 opened on the protective net edge strip 3 and the connecting net edge strip 4, and then installing the bolt 10 in the bolt hole 5, connecting the protective net edge strip 3 and the connecting net edge strip 4 through the bolt 10, and at the same time ensuring that the lower end of the bolt 10 is in the countersunk hole 6 below the connecting net edge strip 4, and the nut 11 is in the countersunk hole 6 above the protective net edge strip 3 to thread the bolt 10, and ensuring that there are no protrusions above the protective net edge strip 3 and below the connecting net edge strip 4, so as to ensure smooth laying.
