DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of the present application.

[0028] Embodiment one:

[0029] Please refer to Figures 1-8 The present application 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 for connecting adjacent protective nets 1 through the connecting net 2, anchor rods 7 are arranged on the upper side of the protective net 1 and the connecting net 2 at equal intervals, positioning cones 8 are arranged on the lower side of the protective net 1 and the connecting net 2 at equal intervals, the anchor rods 7 are anchored in the upper layer of cement paste, and the positioning cones 8 are inserted into the lower layer of asphalt waterproof layer.

[0030] In the specific waterproof layer construction, the waterproof coiled material layer 103 can be laid on the roof first, and the waterproof coiled material can be modified asphalt waterproof coiled material, then the protective net 1 and the connecting net 2 are laid above the waterproof coiled material layer to form the protective net layer 102. Since the lower end surfaces of the protective net 1 and the connecting net 2 are both arrayed with the positioning cone 8, the waterproof coiled material layer 103 below can be pierced by the positioning cone 8 to fasten and fix the waterproof coiled material layer 103, effectively avoiding the cracking of the waterproof coiled material layer 103 in the subsequent use process.

[0031] Through the setting of the anchor rod 7, when the cement slurry layer 101 is laid after the laying of the protective net layer 102, the anchor rod 7 can be embedded into the cement slurry layer 101 to form a stable connection relationship between the cement slurry layer 101, the protective net layer 102 and the waterproof coiled material layer 103, improve the stability, avoid cracking after long-term use, and reduce the problem of waterproof effect.

[0032] However, it is necessary to ensure that the length of the positioning cone 8 is limited, so that the piercing depth of the positioning cone 8 on the upper surface of the waterproof coiled material layer 103 will not exceed 1 / 4 of the thickness of the waterproof coiled material layer 103.

[0033] The connecting mechanism includes the protective net edge strip 3 and the connecting net edge strip 4. The protective net edge strip 3 is arranged at the side edges of the protective net 1 at equal intervals, and the connecting net edge strip 4 is arranged at the side edges of the connecting net 2 at equal intervals. The protective net edge strip 3 is arranged above the connecting net edge strip 4 in correspondence.

[0034] So that in the construction of the protective net layer 102, multiple protective nets 1 are laid, and the adjacent protective nets 1 are connected by the connecting net 2. Specifically, the protective net edge strip 3 on the protective net 1 is aligned with the connecting net edge strip 4 on the connecting net 2. The protective net 1, the connecting net 2, the protective net edge strip 3 and the connecting net edge strip 4 can all be made of PV material, so as to be conveniently connected by rivets or hot melt connection by a hot melt machine.

[0035] The cement slurry flow-through holes 9 are arranged on the edge strips of the protective net 1 and the connecting net 2. In this way, when the cement slurry layer 101 is constructed, the cement slurry can be densely filled in various parts of the protective net layer 102 through the cement slurry flow-through holes 9, so as to ensure the effect of cement slurry laying and filling.

[0036] Example two:

[0037] Please refer to Figures 1-8The application provides a technical scheme: the connecting mechanism further comprises a bolt hole 5, a counterbore 6, a bolt 10 and a nut 11; the bolt hole 5 is arranged on the protective net edge strip 3 and the connecting net edge strip 4; the counterbore 6 is arranged on the upper end of the bolt hole 5 of the protective net edge strip 3 or the lower end of the bolt hole 5 of the connecting net edge strip 4; the bolt 10 is sleeved between the bolt hole 5 of the protective net edge strip 3 and the bolt hole 5 of the connecting net edge strip 4; the upper end of the bolt 10 is threadedly connected with the nut 11; and the lower end of the bolt 10 and the nut 11 are both arranged in the counterbore 6.

[0038] Therefore, when the construction of the protective net layer 102 is performed, the connection between the protective net 1 and the connecting net 2 can also be performed 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, aligning the bolt holes 5 arranged on the protective net edge strip 3 and the connecting net edge strip 4, 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, ensuring that the lower end of the bolt 10 is arranged in the counterbore 6 below the connecting net edge strip 4, the nut 11 is arranged in the counterbore 6 above the protective net edge strip 3 and is threadedly connected with the bolt 10, and no protrusion is arranged above the protective net edge strip 3 and below the connecting net edge strip 4, so that the laying is flat.
