In the building construction requirements, the waterproof capability of the roof is higher. If the roof leaks, accumulated water may seep into the wall body, which may adversely affect the service life and the structural safety of the building. And ponding infiltration indoor back still can reduce indoor user's use experience degree. Therefore, the waterproof and moistureproof functions of the roof are very important. The metal roof 100 provided by the embodiment has good waterproof and moisture-proof performance.

The metal roof 100 mainly includes an outer shell layer 110, an insulation layer 150, a support layer 170 and an acoustic insulation layer 190.

The outer shell 110 can have a primary waterproof effect, and reduce the influence of external rain and other factors on the internal structure and the building of the metal roof 100. Meanwhile, the outer shell layer 110 can also protect the metal roof 100 and provide initial protection for the metal roof 100.

Referring to fig. 1, fig. 2 and fig. 3, fig. 2 is a schematic structural view of a roof panel 112, and fig. 3 is a schematic structural view of a connection structure of a first connection portion 114 and a second connection portion 116. The outer shell 110 generally includes a plurality of roof panels 112, and the plurality of roof panels 112 are collectively joined to form the outer shell 110. Therefore, the maintenance and the replacement of the outer shell layer 110 are more convenient, and the installation flexibility is higher; meanwhile, the roof panel 112 also enables the outer shell 110 to adopt different adaptive contour according to different installation building shapes, and the aesthetic property of the outer shell 110 is enhanced.

Any two adjacent roof panels 112 are clamped, so that any one roof panel 112 can be freely detached, and maintenance and replacement are convenient. And the joint of two adjacent roof panels 112 forms a ventilation channel 111, and air flow in the ventilation channel 111 can take away water vapor when flowing, so that the phenomenon that dew is condensed on the surface of the roof panel 112 due to overlarge moisture concentration to corrode the roof panel 112 and influence the structural strength and the service life of the roof panel 112 is avoided.

In this embodiment, a shielding member 113 is further disposed outside the ventilation channel 111. The shielding member 113 can shield external rainwater and the like, so that the external rainwater is better prevented from entering the ventilation channel 111, and the moisture-proof and waterproof capabilities of the metal roof 100 are enhanced.

The first connection portion 114 is preferably arc-shaped, the second connection portion 116 is provided with a plurality of arc-shaped protrusions, and the second connection portion 116 is surrounded by the first connection portion 114. The second connecting portion 116 is not shaped to match the first connecting portion 114, so that a gap is formed between the two portions after connection, which is beneficial to ventilation. Any two adjacent roof panels 112 are clamped by matching the adjacent first connecting part 114 and the second connecting part 116, so that any two adjacent rib plates 115 together form the ventilation channel 111. Therefore, the ventilation channel 111 does not need to be additionally arranged, and the construction strength is low.

Further, the second connecting portion 116 is further provided with a groove 117, and the groove 117 is located on a side of the second connecting portion 116 close to the free end of the first connecting portion 114 (as shown in fig. 3). Due to the small gap between the second connection portion 116 and the first connection portion 114, external water may flow into the gap between the second connection portion 116 and the first connection portion 114 due to capillary phenomenon, and finally pass through the gap to break through the sealing of the outer shell 110, enter the metal roof 100, and pose a corrosion threat to the internal structure of the metal roof 100. And the setting of recess 117 can increase the distance between second connecting portion 116 and the first connecting portion 114, destroys the condition that capillary phenomenon produced to better avoiding capillary phenomenon's production, isolated outside metal roofing 100 with external moisture as far as possible, reinforcing metal roofing 100's dampproofing and waterproofing performance.

Referring to fig. 1 and 4, fig. 4 is an enlarged schematic view of a portion iv in fig. 1. Further, a waterproof and breathable film 120 is disposed between the outer shell 110 and the insulating layer 150.

Moreover, the roof panel 112 with complete appearance and no damage is more beautiful and more ornamental, thereby improving the visual effect of the metal roof 100.

Referring to fig. 1 and 5, fig. 5 is a schematic structural diagram of the fixing member 130. Further, one end of the fixing member 130 near the support layer 170 is provided with a bridge cut insulation pad 132. There is hot bridge (cold bridge) in the building, for the radiating part of ordinary maintenance structure more easily, for example the utility model provides a mounting 130 etc. consequently near mounting 130 very easily because the reason of the difference in temperature produces the steam condensation and forms the drop of water, easily causes the corruption to the structure of metal roofing 100, influences structural strength and life. And through the setting of bridge cut-off heat insulating mattress 132, can reduce thermal transmission better, not only can reach and reduce heat and scatter and disappear in winter or reduce heat and get into indoor purpose in summer, but also can avoid mounting 130 annex to produce steam better, guarantee mounting 130 operational environment's drying, the indirect life who prolongs mounting 130.

Please refer to fig. 1 again. The heat insulating layer 150 can preferably prevent heat conduction between the interior of the building and the outer shell 110, thereby suppressing temperature variation in the interior of the building, and enabling the interior of the building to be maintained at a stable temperature. In this embodiment, heat preservation 150 can adopt heat preservation soundproof glass cotton to set up the three-dimensional double-layered muscle heat reflection function aluminium foil, thereby guarantee that the thermal-insulated respond well that keeps warm.

The supporting layer 170 can support and fix the metal roof 100, and can increase the distance between the outer shell 110 and the building, thereby increasing the difficulty of heat exchange between the outer shell 110 and the building, better avoiding the phenomenon that the water vapor is more condensed due to the larger temperature difference between the outer shell 110 and the building, reducing the water vapor concentration inside the metal roof 100 as much as possible, keeping the drying inside the metal roof 100, and providing a good working environment for the parts inside the metal roof 100. In this embodiment, the support layer 170 may adopt an inner support system mainly composed of lining purlins 172 and lining purlin seats 174, and the support effect is good.

In this embodiment, the sound insulation layer 190 can be made of sound-absorbing glass wool and sound-absorbing non-woven fabric, so as to comprehensively reduce noise.

The working principle of the metal roof 100 is as follows:

when the outside rains, the outer shell 110 first plays a role of water-proofing, and isolates the outside rainwater outside the metal roof 100. Meanwhile, the shielding member 113 can block external rainwater from directly entering the gap between the first connecting portion 114 and the second connecting portion 116.

Because the fixing piece 130 is located in the ventilation channel 111, structural damage to the roof panel 112 is avoided, and a damaged leak of the roof panel 112 is avoided, so that external moisture is prevented from entering the metal roof 100 from a damaged position, and the waterproof and moistureproof performance of the metal roof 100 is enhanced.

When external rainwater enters the gap between the first connection portion 114 and the second connection portion 116 due to capillary phenomenon, the groove 117 on the second connection portion 116 can prevent rainwater from entering the ventilation channel 111 through capillary phenomenon.

When the air current in ventilation channel 111 flows, can take away the steam in the air together, and then reduce steam concentration, avoid moisture concentration too big, lead to condensing at roof boarding 112's internal surface and produce the dew to reinforcing metal roofing 100's humidity resistance.

When the water is accumulated in the outer shell 110, the waterproof breathable film 120 can exert a waterproof effect, so that the water is prevented from continuously permeating into a building, and the waterproof and moistureproof effects are exerted.

The arrangement of the heat insulating layer 150 can reduce the temperature difference between the inside and the outside of the outer shell layer 110, thereby reducing the possibility of condensation of water drops on the surface of the outer shell layer 110 due to the temperature difference, and further enhancing the waterproof and moisture-proof performance of the metal roof 100.

The setting of bridge cut-off heat insulating mattress 132 can reduce the difference in temperature of mounting 130 and external world to reduce the mounting 130 surface because the difference in temperature produces the possibility that the drop of water condenses, make the inside drier environment that keeps of metal roofing 100, both strengthened metal roofing 100's humidity resistance, provide a dry operational environment for metal roofing 100's inside components and parts again, indirectly prolonged metal roofing 100's life.
