[0002] The roof waterproofing layer is one of the topmost external protective components of a building. Its main purpose is to prevent rainwater, snow water, etc. from penetrating into the interior of the building, to resist the influence of adverse factors such as rain, snow, wind, frost, etc. in nature, and to ensure that the interior of the building is dry and comfortable.

[0003] Roof waterproofing projects generally include roofing membrane waterproofing, roofing membrane waterproofing, roofing rigid waterproofing, tile roofing waterproofing, and roofing joint sealing waterproofing. With the development of technology, most existing roofs are cast in concrete, so roofing membrane waterproofing is also widely used. Usually a layer of foam concrete is laid on top of the roofing membrane waterproofing as a filler. However, during long-term use, the waterproofing membrane layer may be affected by thermal expansion and contraction and deform, which will also affect the foam concrete filled and laid above it, causing cracking of the foam concrete layer, further affecting the waterproofing membrane layer below it, and causing the overall waterproofing preservation layer to crack and fail. At present, such cracking is also a common problem of existing roof waterproofing protective layers and cannot be effectively solved. Therefore, a crack-resistant reinforcement structure for the roof waterproofing protective layer is proposed. ‌‌‌‌ Utility Model Content

[0020] 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.

[0021] Example 1:

[0022] See also Figure 1-6 The utility model provides a technical solution: a roof waterproof protective layer anti-cracking reinforcement structure, including an arc angle piece 2 and a reinforcement net 8. A countersunk hole 3 is opened on the arc angle piece 2, and a screw 4 is arranged in the countersunk hole 3. The arc angle piece 2 is installed at the corner of the parapet 1 through the screw 4.

[0023] like Figure 1 As shown, the head of the bolt 4 can be completely embedded in the countersunk hole 3, so that when the arc angle piece 2 is installed to the corner of the parapet 1, the screw 4 will not protrude from the arc surface of the arc angle piece 2, and therefore will not affect the subsequent laying of the waterproof membrane and the laying of the reinforcement net 8. In addition, countersunk holes 3 are provided on both side frames of the arc angle piece 2, so that the arc angle piece 2 can be firmly connected to the side of the roof and the parapet 1 with screws 4, thereby improving the stability of the installation.

[0024] The side of the arc angle piece 2 close to the parapet 1 is a right angle surface, while the side away from the parapet 1 is an arc surface. Countersunk holes 3 are provided on both side frames of the arc angle piece 2.

[0025] The waterproof roll material layer 7 is laid above the arc surface of the arc corner piece 2, and the reinforcement net 8 is laid above the waterproof roll material layer 7. The waterproof roll material layer 7 and the reinforcement net 8 both extend to the arc corner piece 2 on the side of the parapet 1 and are located between the arc corner piece 2 and the rotating plate 6.

[0026] A plurality of partitions 5 are connected to the top of the arc angle member 2 at equal intervals, and a rotating plate 6 is rotatably connected to the upper end of the arc angle member 2. A waterproof membrane layer 7 and a reinforcement net 8 are arranged between the rotating plate 6 and the surface of the arc angle member 2. A bolt 9 is connected through a thread on the rotating plate 6. The bolt 9 passes through the rotating plate 6, the waterproof membrane layer 7 and the reinforcement net 8, and is connected to the parapet 1.

[0027] like Figure 1 As described above, the setting of the turning plate 6 is convenient for reversing it, so that when laying the waterproof membrane and the reinforcement net 8, the turning plate 6 can be flipped upwards without affecting the paving construction on the arc surface of the arc angle piece 2. After the paving is completed, it is rotated and dropped, and then the bolts 9 are installed, so that the side edges of the waterproof membrane layer formed by the paving of the waterproof membrane and the reinforcement net layer formed by the paving of the reinforcement net 8 can be firmly connected to the side of the parapet 1 through the arc angle piece 2.

[0028] The provision of the partitions 5 facilitates the stable filling of the foam concrete between the partitions 5 when filling the foam concrete after the waterproof membrane layer and the reinforcement mesh layer are laid, thereby achieving stable covering and filling of the arc angle pieces 2.

[0029] The side edges of the reinforcement mesh 8 are integrally provided with a frame 10, and the upper side of the reinforcement mesh 8 is also connected with a plurality of reinforcement rods 11 in an array. When the foam concrete is filled on top of the laid reinforcement mesh 8, the foam concrete will not be completely in contact with the waterproof membrane, but will be excessively affected by its thermal expansion and contraction, so that the thermal expansion and contraction of the waterproof membrane will act more on the reinforcement mesh 8, so as to reduce the possibility of subsequent cracking of the foam concrete. At the same time, the setting of the reinforcement rods 11 allows it to be embedded in the foam concrete. When the foam concrete is deformed and cracked, the reinforcement rods 11 can also play a role of pulling and reinforcing to a certain extent, thereby further reducing the possibility of cracking of the foam concrete and improving the protection of the waterproof membrane layer below it.

[0030] A card strip 12 is connected to the frame 10, and a card plate 13 is provided between the card strips 12 of adjacent reinforcement nets 8, and a card slot 15 is connected to the card plate 13. The card slot 15 cooperates with the card plate 13 to form a card sleeve. In this way, when laying the reinforcement net 8, it is convenient to connect the adjacent reinforcement nets 8, and the paving is convenient. It can also improve the stability between the reinforcement nets 8 after the subsequent filling of foam concrete, thereby improving the overall stability.

[0031] The clamping plate 13 is provided with an opening 14 , and the provision of the opening 14 helps the foam concrete to flow through the opening 14 to between adjacent reinforcement meshes 8 , thereby improving the density of the foam concrete filling.
