Description

Roofing System Technical Field

[0001] This application pertains to building roof structures, specifically roof systems. Background Technology

[0002] Existing explosion-proof roofs primarily provide explosion protection for single-layer or sandwich panel systems. They rely on a single chain to pull the single-layer or sandwich panel to prevent components from flying off the roof and injuring people during an explosion. For roofs with double-layer structures, currently only a single chain can be used to pull the bottom panel. Typically, only the bottom panel is lifted during an explosion, but the possibility of the top panel being lifted due to excessive explosion energy cannot be ruled out, thus the risk of the top panel flying off the roof remains. Summary of the Invention

[0003] In view of at least one of the above-mentioned defects or deficiencies in the prior art, this application provides a roofing system that can effectively and stably traction the double-layer structure of the roof, thereby improving safety during explosion venting.

[0004] To achieve the above objectives, this application provides a roofing system comprising:

[0005] A first waterproofing membrane and a second waterproofing membrane are arranged alternately, one above the other, and are laid on the purlins of the roof. The second waterproofing membrane has through holes in its body.

[0006] A first chain and a second chain, wherein the two ends of the first chain are respectively formed as a first anchoring end and a first traction end, the first traction end is connected to the first waterproof membrane, and the first anchoring end is connected to the purlin through the through hole of the membrane; the two ends of the second chain are respectively formed as a second anchoring end and a second traction end, the second traction end is connected to the second waterproof membrane, and the second anchoring end is connected to the purlin.

[0007] In some embodiments, the roofing system includes a transition connector that partially passes through a through-hole in the panel to be securely connected to the purlin, and the first anchoring end is connected to the transition connector.

[0008] In some embodiments, the transition connector includes, along the axial direction, a threaded portion for threading the purlin and a connecting portion extending from the through hole in the plate, the connecting portion forming a threaded connection with the first anchoring end.

[0009] In some embodiments, the connection portion is provided with an axially penetrating internal threaded hole, and the roofing system includes a first bolt that sequentially connects the first anchoring end and the internal threaded hole.

[0010] In some embodiments, the second waterproof membrane includes a second waterproof roll and a second plate body stacked sequentially on top of each other, and the transition connector includes an overlapping skirt extending radially along the joint, the overlapping skirt overlapping the second waterproof roll to cover the gap between the joint and the through hole of the plate body.

[0011] In some embodiments, the bottom of the connecting part is provided with a positioning disk that extends radially, the outer diameter of the positioning disk being larger than the outer diameter of the screw part and used to abut against the surface of the purlin.

[0012] In some embodiments, the first waterproof membrane includes a first plate body, a waterproof and breathable membrane, and a thermal insulation layer stacked sequentially, and the first traction end passes through the thermal insulation layer and the waterproof and breathable membrane in sequence to connect to the first plate body.

[0013] In some embodiments, the first waterproof membrane further includes a first waterproof membrane covering the first membrane body, and the roofing system includes a first covering and a second bolt sequentially passing through the first waterproof membrane, the first membrane body and the first traction end, the first covering covering the nut of the second bolt and the gap between the second bolt and the first waterproof membrane.

[0014] In some embodiments, the second waterproof membrane includes a second waterproof membrane and a second plate body stacked sequentially on top of each other, and the roofing system includes a second membrane and a third bolt that sequentially connects the second waterproof membrane, the second plate body and the second traction end, wherein the second membrane covers the nut of the third bolt and the gap between the third bolt and the second waterproof membrane.

[0015] In some embodiments, the roofing system includes an intermediate support member disposed between the first and second waterproofing sheets to support the first waterproofing sheet.

[0016] Through the above technical solution, the roof system of this application can effectively pull the first and second waterproof panels using the first and second chains respectively. When the roof is lifted due to explosion venting, the second waterproof panel can avoid the first chain through its own through-hole, thus not interfering with the effective lifting and explosion venting of the second waterproof panel. When the explosion energy is too large and simultaneously blows away the first and second waterproof panels, under the traction of the first and second chains, neither the first nor the second waterproof panel will be blown away, thus effectively protecting the safety of personnel on the ground.

[0036] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0037] The present application will now be described in detail with reference to the accompanying drawings and exemplary embodiments.

[0038] As shown in Figures 1 and 2, a first exemplary embodiment of this application provides a roofing system, which includes a first waterproofing membrane 1, a second waterproofing membrane 2, a first chain 3, and a second chain 4. The first waterproofing membrane 1 and the second waterproofing membrane 2 are arranged sequentially at intervals and are laid on purlins 5 of the roof. The second waterproofing membrane 2 has a through hole 201. The two ends of the first chain 3 are respectively formed as a first anchoring end and a first traction end. The first traction end is connected to the first waterproofing membrane 1, and the first anchoring end is connected to the purlin 5 through the through hole 201. The two ends of the second chain 4 are respectively formed as a second anchoring end and a second traction end. The second traction end is connected to the second waterproofing membrane 2, and the second anchoring end is connected to the purlin 5.

[0039] Therefore, the roof system of this exemplary embodiment adopts a double-layer roof structure. The second waterproofing board 2, as the inner layer of the roof, provides good aesthetics and thermal insulation, while the first waterproofing board 1, as the outer layer, meets the aesthetic requirements of the roof exterior. Furthermore, even if water seeps down from the first waterproofing board 1, the second waterproofing board 2 effectively prevents water from penetrating the interior and allows it to drain away from its surface, improving the roof's waterproofing effect. The first chain 3 and the second chain 4 effectively traction the first and second waterproofing boards 1 and 2 respectively. When the roof experiences a burst and lifts the second waterproofing board 2, the second waterproofing board 2 can avoid the first chain 3 through its through-hole 201, ensuring that the first chain 3 does not interfere with the lifting action of the second waterproofing board 2, thus achieving effective burst venting. Simultaneously, if the burst force is too great and blows the second waterproofing board 2 away, the second chain 4 can promptly catch it, preventing it from falling off the roof. Similarly, when the explosion venting force further increases and blows away the first waterproof panel 1, the first chain 3 can promptly hold the first waterproof panel 1, preventing it from falling off the roof and thus effectively protecting the safety of personnel on the ground. Overall, the roofing system of this application has good explosion-proof performance and is suitable for use on roofs with double-layer panel structures. While meeting the roof design requirements, it can ensure the safety of roof explosion venting.

[0040] In one embodiment, the roofing system includes a transition connector 6, through which the first chain 3 is indirectly connected to the purlin 5. Specifically, the transition connector 6 partially passes through the panel through-hole 201 to be fixedly connected to the purlin 5, and the first anchoring end of the first chain 3 is connected to the transition connector 6. When the second waterproof membrane 2 is lifted due to a burst, the second waterproof membrane 2 can pass through the panel through-hole 201 sequentially through the transition connector 6 and the first chain 3, thus not affecting the lifting of the second waterproof membrane 2. Crucially, before laying the second waterproof membrane 2, the transition connector 6 can be pre-installed on the purlin 5. When laying the second waterproof membrane 2, simply aligning the panel through-hole 201 with the transition connector 6 completes the installation. The transition connector 6 provides a more stable anchor point for the fixed connection of the first chain 3, facilitating the installation and removal of the first chain 3.

[0041] In one embodiment, the transition connector 6 can be screwed to the purlin 5 for easy assembly and disassembly. Specifically, the transition connector 6 includes a screw portion 601 and a connecting portion 602 along the axial direction. The screw portion 601 is used to screw into the purlin 5 to ensure its anchoring force on the purlin 5. The connecting portion 602 extends out from the plate through hole 201 and can form a threaded connection with the first anchoring end, thereby facilitating the installation of the first chain 3.

[0042] Furthermore, the connecting part 602 may be provided with an axially penetrating internal threaded hole 6021, and the roof system includes a first bolt 7 that sequentially connects the first anchoring end and the internal threaded hole 6021. The first bolt 7, the first anchoring end, and the internal threaded hole 6021 can lock the first chain 3 and the transition connector 6.

[0043] In one embodiment, as shown in Figures 3 and 4, the second waterproof membrane 2 includes a second waterproof roll 202 and a second panel 203 stacked sequentially. The transition connector 6 includes an overlapping skirt 603 extending radially along the joint 602. The overlapping skirt 603 overlaps the second waterproof roll 202 to cover the gap between the joint 602 and the through hole 201 in the panel. Specifically, the overlapping skirt 603 can be welded to the second waterproof roll 202. When the roof is vented and the second waterproof membrane 2 is lifted, the overlapping skirt 603 can be disconnected from the second waterproof roll 202 to facilitate the lifting of the second waterproof roll 202. Of course, when no venting is performed, the overlapping skirt 603 can completely seal the through hole 201 in the panel to prevent roof leakage.

[0044] In one embodiment, as shown in FIG3, the bottom of the connecting part 602 is provided with a positioning disk 604 extending radially. The outer diameter of the positioning disk 604 is larger than the outer diameter of the screw part 601 and is used to abut against the surface of the purlin 5. Thus, when the screw part 601 is inserted into the purlin 5, the positioning disk 604 can abut against the purlin 5, making the installation of the transition connector 6 more stable.

[0045] In one embodiment, the first waterproof panel 1 is a composite panel with an internal waterproof layer design. Specifically, the first waterproof panel 1 includes a first panel 101, a waterproof and breathable membrane 102, and an insulation layer 103 stacked sequentially. The first panel 101 can be made of aluminum-magnesium-manganese steel or other special decorative materials, which can accommodate aesthetics, corrosion resistance, and installation of external auxiliary systems. The waterproof and breathable membrane 102 is located inside the first panel 101 and can be laminated with the first panel 101 during production, such as forming a laminated plastic steel tile. The waterproof and breathable membrane 102 uses a membrane material that is difficult for water to pass through directly but allows water vapor to pass through directly. On the one hand, it can prevent water leaking from the first panel 101 from entering the insulation layer 103; on the other hand, the moisture absorbed by the insulation layer 103 can also evaporate as water vapor and be released from the waterproof and breathable membrane 102, and evaporate from the gaps in the first panel 101, avoiding the problems of condensation inside the insulation layer 103 and water not being able to drain.

[0046] When the first waterproof membrane 1 has the aforementioned multi-layer structure, to ensure a stable connection between the first chain 3 and the first waterproof membrane 1, the first traction end of the first chain 3 can sequentially pass through the insulation layer 103 and the waterproof breathable membrane 102 to connect to the first plate body 101. Since the first plate body 101 is relatively rigid, this helps improve the connection stability with the first chain 3. Although the first chain 3 will form a through hole after passing through the insulation layer 103 and the waterproof breathable membrane 102, the waterproof effect of the first waterproof membrane 1 can be guaranteed by sealing the through hole with the waterproof tape 12 shown in Figure 1. In this embodiment, the waterproof tape 12 can be made of materials such as aluminum foil tape or butyl tape; this application does not limit the application to this material.

[0047] To ensure traction stability, the first traction end can be fastened to the first plate 101 using a bolt and nut assembly, as shown in Figure 1. The roofing system is equipped with a second bolt 8, which passes through the first plate 101, the first traction end, and the nut in sequence, thereby locking the first traction end to the first plate 101. The second bolt 8 can be used in conjunction with a metal washer made of waterproof material such as rubber on the back. This metal washer is placed between the nut of the second bolt 8 and the first plate 101, effectively sealing the perforation of the first plate 101. Furthermore, depending on the actual situation, the perforation of the second bolt 8 can be sealed with adhesive to ensure that the waterproof effect of the first waterproofing plate 1 is not compromised.

[0048] In one embodiment, the first waterproof membrane 1 is a composite panel with an external waterproof layer. Specifically, the first waterproof membrane 1 further includes a first waterproof membrane (not shown in the figures) covering the first panel 101, such as a TPO waterproof membrane. By covering the first panel 101 with the first waterproof membrane, the waterproof effect of the first waterproof membrane 1 can be improved. When the first traction end is fastened using the second bolt 8, the second bolt 8 needs to be sequentially connected through the first waterproof membrane, the first panel 101, and the first traction end. To avoid damaging the waterproof effect of the first waterproof membrane due to the second bolt 8, a first covering film (not shown in the figures) can be added. The first covering film covers the nut of the second bolt 8 and the gap between the second bolt 8 and the first waterproof membrane. Preferably, the first covering film can be made of the same material as the first waterproof membrane, so that the two can be welded together to prevent leakage at the connection point of the second bolt 8 on the first waterproof membrane 1.

[0049] In addition, the first waterproof board 1 also includes a purlin disposed in the insulation layer 103, which can serve as a support to support some irregularly shaped first board bodies 101, while ensuring that the insulation performance of the first waterproof board 1 will not be reduced.

[0050] In one embodiment, the second waterproof membrane 2 includes a second waterproof roll 202 and a second plate 203 stacked sequentially. The second waterproof roll 202 can be a TPO waterproof roll, and the second plate 203 is a metal plate such as a color-coated steel plate or a galvanized plate. The first waterproof membrane 1 and the second waterproof membrane 2 together can form a double waterproof and heat-insulating effect. The roofing system also includes a second membrane 9 and a third bolt 10 that sequentially connects the second waterproof roll 202, the second plate 203, and the second traction end. The second membrane 9 covers the nut of the third bolt 10 and the gap between the third bolt 10 and the second waterproof roll 202. Preferably, the second membrane 9 can be made of the same material as the second waterproof roll 202, so that the two can be welded together to prevent leakage at the connection point of the third bolt 10 on the second waterproof membrane 2.

[0051] In one embodiment, the roofing system includes an intermediate support 11 disposed between a first waterproofing liner 1 and a second waterproofing liner 2 to support the first waterproofing liner 1, thereby spacing the first waterproofing liner 1 from the second waterproofing liner 2. As shown in FIG1, the intermediate support 11 can be installed on a purlin 5 to provide stable support for the first waterproofing liner 1.
