The water vapor trapped in the insulation board for a long time also breeds mold, affecting the indoor air quality.
[0003] In the actual roofing, workers dig grooves on the insulation board as exhaust channels during construction, and this method not only damages the structure of the insulation board, but also cannot guarantee the quality and arrangement of the grooves to effectively remove water vapor, so the exhaust effect is generally poor and needs to be improved.

[0026] As Figure 1 shown, the present embodiment provides a thermal and waterproof structure for roofing, mainly used for steel roofing, especially for lightweight roofing laying, but the present application is not limited thereto.
[0027] The thermal and waterproof structure comprises a thermal layer 1, a ventilation and drainage layer 2 and a waterproof layer 3, the ventilation and drainage layer 2 is located above the thermal layer 1, and the waterproof layer 3 is located above the ventilation and drainage layer 2.
[0028] The top surface of the thermal layer 1 is provided with an adhesive layer 4, the ventilation and drainage layer 2 is fixedly connected with the thermal layer 1 through the adhesive layer 4, and the bottom surface of the waterproof layer 3 is fixedly connected with the ventilation and drainage layer 2 through pasting or melting, so as to connect the thermal layer 1, the ventilation and drainage layer 2 and the waterproof layer 3 into an integrated body for prefabricated production.
[0029] Among them, the thermal layer 1 is a thermal insulation board, which can adopt XPS board (extruded polystyrene foam board), EPS board (expanded polystyrene board) or PIR board (polyisocyanurate board) and the like.
[0030] The ventilation and drainage layer 2 is a three-dimensional net structure woven by flexible wires 21, which is hollow, providing space and channels for the water vapor in the thermal layer 1 or the water vapor permeated from the waterproof layer 3 to escape and disperse. The three-dimensional net structure is formed by a planar net downwardly tapered to form a plurality of support grooves 22, and the ventilation and drainage layer 2 is integrally woven by the flexible wires 21 in a random manner, so that the wires generate random directional tension between each other, improving the buffering capacity of the ventilation and drainage layer 2, and thus better maintaining the three-dimensional shape.
[0031] Among them, the taper of the support groove 22 is preferably between 2 / 3-1, so as to ensure that the support groove 22 has a better supporting force. The opening diameter of the support groove 22 is preferably 1-1.5 cm.
[0032] More specifically, the plurality of support grooves 22 are divided into a plurality of rows, each row uniformly spaced a plurality of support grooves 22, and the support grooves 22 of adjacent rows are distributed in a staggered manner to improve the support strength of the ventilation and drainage layer 2.
[0033] In addition, as shown in Figure 2 , the ventilation and drainage layer 2 further comprises a plurality of warp wires 23 and a plurality of weft wires 24, which are both wave-shaped, the warp wires 23 extend along the horizontal direction, and the wave shape is vertical bending, and the weft wires 24 extend along the horizontal direction, and the wave shape is also vertical bending, and the wave peaks of the warp wires 23 and the wave peaks of the weft wires 24 are cross-connected with each other, and the wave valleys of the warp wires 23 and the wave valleys of the weft wires 24 are cross-connected with each other, that is, the wave peak of one warp wire 23 and the wave peak of one weft wire 24 are cross-connected, and the wave valleys on both sides of the wave peak of the warp wire 23 are cross-connected with the wave valleys of the other two adjacent weft wires 24, and the same arrangement is made between the plurality of warp wires 23 and the plurality of weft wires 24, forming an array net connection.
[0034] The valley part formed by the intersection of the warp yarn 23 and the weft yarn 24 forms the framework of the support groove 22, and the tenacity yarn 21 is woven around the valley part formed by the intersection of the warp yarn 23 and the weft yarn 24 to form the support groove 22.
[0035] The present embodiment strengthens the overall structural strength and support strength of the ventilation and drainage layer 2 by the arrangement of the warp yarn 23 and the weft yarn 24, and provides a shape basis for the weaving of the tenacity yarn 21.
[0036] Further, the yarn body of the warp yarn 23 and the weft yarn 24 is bent with a plurality of small wave segments, and the wave shape of the small wave segments is smaller than the wave shape of the support groove 22 formed by the warp yarn 23 and the weft yarn 24. The small wave segments are used to improve the anti-skid ability of the warp yarn 23 and the weft yarn 24, and prevent the tenacity yarn 21 wound on the warp yarn 23 and the weft yarn 24 from sliding.
[0037] In addition, in order to further improve the connection degree of the tenacity yarn 21 and the warp yarn 23 and the weft yarn 24, the yarn body of the warp yarn 23 and the weft yarn 24 corresponding to the support groove 22 is further bent with a ring-shaped ear 25, the tenacity yarn 21 passes through the ring-shaped ear 25, and the tenacity yarn 21 and the warp yarn 23 and the weft yarn 24 are stably connected through the ring-shaped ear 25, thereby improving the connection stability of the overall structure of the ventilation and drainage layer 2.
[0038] In the present embodiment, the warp yarn 23 and the weft yarn 24 are thick yarns, the diameter of which is 1.5-2 times the diameter of the tenacity yarn 21, and the diameter of the tenacity yarn 21 is preferably 1-1.5mm.
[0039] The tenacity yarn 21, the warp yarn 23 and the weft yarn 24 can all be made of polypropylene, polyester fiber or nylon material.
[0040] The waterproof layer 3 can be made of a roll of high polymer waterproof material such as EVA, PVC, EPDM or TPO.
[0041] In addition, a fire-retardant layer 5 can also be fixed above the waterproof layer 3, and the fire-retardant layer 5 can be made of a board material such as a silicate board or a rock wool board.
[0042] The roof waterproof and heat-insulating structure provided by the present application has the advantages that the three-dimensional net-like design of the ventilation and drainage layer 2 not only provides a channel for the evaporation and escape of water vapor in the heat-insulating layer 1, but also facilitates the flow of air, thereby further improving the water vapor emission effect, and in addition, the slow air heat conduction property of the ventilation and drainage layer 2 is combined with the heat-insulating layer 1 to improve the heat-insulating effect.
[0043] In addition, in the present application, the heat-insulating layer 1, the ventilation and drainage layer 2 and the waterproof layer 3 are prefabricated into an integrated whole, which can be directly used during roof paving without the need for on-site processing during construction, thereby not only saving the process and improving the paving efficiency, but also ensuring the ventilation and drainage effect of the roof.
