[0050] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.
[0051] The roofing system 100 according to the present application will be described below with reference to the accompanying drawings.
[0052] like Figure 1 and Figure 2 As shown, a specific embodiment of the present application provides a roofing system 100, including a plurality of roof panels 3, wherein the panel edges of any two adjacent roof panels 3 are used as curling edges to form a multiple curling edge structure 1 that is interlocked and connected with each other, the roof panels 3 include a base layer 31 and a rolled waterproof layer 32 covering the base layer 31, and the bite seam 2 of the multiple curling edge structure 1 is provided with a waterproof sealing structure.
[0053] The house roof structure includes a main roof structure and a roof waterproof structure laid on the main roof layer. A roof system 100 formed by a plurality of roof panels 3 is installed on the top of the house structure to form the house roof structure, wherein the base layer 31 is used to form the main roof structure, and the roll waterproof layer 32 is used to form the roof waterproof structure. In the present application, the construction of the house roof structure is completed by the roof panel 3 having a concrete layer and a waterproof roll layer, thereby realizing the simultaneous construction of the main roof structure and the roof waterproof structure, thereby shortening the construction period of the house roof structure.
[0054] Specifically, the base layer 31 and the waterproofing roll 32 in the prior art are separated and constructed successively, wherein the waterproofing roll 32 is constructed after the base layer 31 is constructed. Multiple waterproofing rolls 32 are spliced with each other by hot-melt connection to form a closed roof waterproof structure. The waterproofness of the roof waterproof structure depends on the airtightness of the lap joints of adjacent waterproofing rolls 32, and the airtightness of the lap joints depends on the quality of the hot-melt connection operation of the operator. Therefore, the waterproofness of the roof waterproof structure cannot be guaranteed, resulting in water leakage. In addition, the hot-melt connection operation has a complex process and a long construction time.
[0055] In the present application, the roof panels 3 are connected by using the edge of the roof panel 3 as a curling edge to form a multiple curling edge structure 1 that is interlocked and connected to each other, thereby simplifying the connection process of the roll waterproofing layer 32, thereby shortening the construction period of the roof structure of the house and ensuring the waterproofness of the roof waterproof structure.
[0056] It should be noted that in the specific embodiment of the present application, unless otherwise stated, the waterproofing roll layer 32 and the base layer 31 are stacked in the up and down direction, wherein the waterproofing roll layer 32 is located above the base layer 31; the roof panels 3 are spliced with each other in the left and right direction.
[0057] Those skilled in the art can understand that a multiple curling structure refers to a tightly overlapping structure formed by two plate edges being adhered to each other and subjected to multiple bending deformations. The number of curling layers in a multiple curling structure refers to the number of overlapping plates after the multiple curling structure is radially cut open. A multiple curling structure is one in which the number of curling layers exceeds two. Common ones include a double curling structure and a triple curling structure. The double curling structure includes five overlapping curling layers, and the triple curling structure includes seven overlapping curling layers.
[0058] like Figures 3 to 6 As shown, in some embodiments, the roof panel 3 includes a main body 4 and two panel edges, and the two panel edges are respectively a first panel edge 5 and a second panel edge 6, the first panel edge 5 is located on the left side of the main body 4, and the second panel edge 6 is located on the right side of the main body 4.
[0059] Preferably, the multiple curling structure 1 formed by the first plate edge 5 and the second plate edge 6 is a double curling structure, the double curling structure includes five layers of curling arranged in a stacked manner, and the seam wall surface of the bite seam 2 is a flat structure. The construction process of connecting the roof panels 3 by using the double curling structure is relatively simple, and the seam wall surface is a flat structure, which can make the seam wall surfaces of the bite seam 2 highly fit each other, thereby reducing the size of the bite seam 2 to improve the waterproofness of the roofing system 100.
[0060] Specifically, the first board edge portion 5 includes a first vertical section 51, a first horizontal section 52, and a third vertical section 53 connected in sequence. The first vertical section 51 and the third vertical section 53 both extend in the up-down direction, the first horizontal section 52 extends in the left-right direction, the lower end of the first vertical section 51 is connected to the left end of the main body 4, the right end of the first horizontal section 52 is connected to the upper end of the first vertical end, and the upper end of the third vertical section 53 is connected to the left end of the first horizontal section 52. The second board edge portion 6 includes a second vertical section 62 and a second horizontal section 61 connected in sequence. The second vertical section 62 extends in the up-down direction, the second horizontal section 61 extends in the left-right direction, the lower end of the second vertical section 62 is connected to the right end of the main body 4, and the left end of the second horizontal section 61 is connected to the upper end of the second vertical section 62.
[0061] like Figures 7 to 11 As shown, the specific bending and curling construction process is as follows:
[0062] The first step is to buckle the second plate edge 6 with the first plate edge 5, specifically, to fit the right side of the second vertical section 62 with the left side of the first vertical section 51, and to fit the upper side of the second horizontal section 61 with the lower side of the first horizontal section 52, and the second horizontal section 61 is located between the first vertical section 51 and the third vertical section 53;
[0063] Step 2: bend the third vertical section 53 to the right to form a first plugging groove 7 with the first horizontal section 52 to be plugged with the second horizontal section 61;
[0064] Step 3: bend the second horizontal section 61, the first horizontal section 52 and the third vertical section 53 downward, so that the second horizontal section 61 and the second vertical section 62 form a second plugging groove 8 that is plugged and matched with the third vertical section 53;
[0065] The notch of the first plug-in slot 7 faces upward, the notch of the second plug-in slot 8 faces downward, and a bite seam 2 is formed between the third vertical section 53 and the second vertical section 62 .
[0066] The double curling structure formed by the above bending and curling construction includes a first curling and a second curling, wherein the first curling includes a first layer curling 14, a third layer curling 16 and a fifth layer curling 18 that are curled from the outside to the inside and connected in sequence, a first transition section is connected between the first layer curling 14 and the third layer curling 16, and a third transition section is connected between the third layer curling 16 and the fifth layer curling 18; the second curling includes a second layer curling 15 and a fourth layer curling 17 that are curled from the outside to the inside and connected in sequence, and a second transition section is connected between the second layer curling 15 and the fourth layer curling 17; the third layer curling 16, the fifth layer curling 18 and the third transition section form a first plug-in groove 7 that is plug-matched with the fourth layer curling 17, the second layer curling 15, the fourth layer curling 17 and the second transition section form a second plug-in groove 8 that is plug-matched with the fifth layer curling 18, and a bite seam 2 is formed between the fifth layer curling 18 and the second layer curling 15.
[0067] In fact, after the first step of bending and curling construction, the first vertical section 51 forms the first layer of curling 14, and the second vertical section 62 forms the second layer of curling 15; after the second step of bending and curling construction, the third vertical section 53 forms the fifth layer of curling 18 and the third transition section; after the third step of bending and curling construction, the first horizontal section 52 forms the third layer of curling 16 and the first transition section, and the second horizontal section 61 forms the fourth layer of curling 17 and the second transition section.
[0068] Preferably, the rolled waterproof layers 32 on the seam wall surfaces on both sides of the bite seam 2 are heat-melt welded to each other to form a waterproof sealing structure, and the bite seam 2 is sealed by the waterproof sealing structure, thereby preventing excessive water accumulation on the house roof structure from entering the gap between the roof panels 3 through the bite seam 2, thereby enhancing the waterproofness of the roofing system 100, and the connection of the seam wall surfaces of the bite seam 2 is strengthened by heat-melt welding the rolled waterproof layers 32 to strengthen the strength of the multiple curling structure 1, thereby strengthening the mutual connection between the multiple roof panels 3.
[0069] Specifically, after the double curling structure is formed by the bending and curling construction, the third vertical section 53 and the second vertical section 62 are respectively used as the seam wall surface of the bite seam 2. After the second step of the bending and curling construction, the hot melting operation is performed, and the hot melting area 12 is formed on the third vertical section 53 and the second vertical section 62 respectively; after the third step of the bending and curling construction is performed, the welding operation is performed, and the welding area 13 is formed between the third vertical section 53 and the second vertical section 62, that is, the roll waterproof layer 32 on the seam wall surface of the bite seam 2 is hot-melted and welded to each other. Since the roll waterproof layer 32 is solid and non-viscous at room temperature, it liquefies and becomes viscous after being heated to the melting point. Therefore, after the hot melting operation, the third vertical section 53 needs to be bent as soon as possible to bond with the roll waterproof layer 32 on the second vertical section 62, so that the roll waterproof layer 32 on the third vertical section 53 and the roll waterproof layer 32 on the second vertical section 62 can be combined with each other to form a waterproof sealing structure after cooling.
[0070] Preferably, the roofing system 100 further comprises a sealing member 11 capable of being heat-meltedly connected to the waterproof roll material layer 32 , and the sealing member 11 is heat-meltedly welded to the waterproof roll material layer 32 on the seam wall surfaces on both sides of the bite seam 2 to form a waterproof sealing structure.
[0071] Specifically, after the double curling structure is formed by bending and curling construction, the seal 11 is arranged at the lower open end of the bite seam 2 and seals the entire bite seam 2, thereby preventing excessive water accumulation on the roof structure of the house from entering the gap between the roof panels 3 through the bite seam 2, thereby enhancing the waterproofness of the roof system 100.
[0072] Furthermore, the third vertical section 53 is located above the main body 4, and the seal 11 not only seals the bite seam 2 but also fills between the third vertical section 53 and the main body 4 and is connected to the second vertical section 62. In the rainy season, water on the roofing system 100 for a long time will corrode the roll waterproofing layer 32 on the second vertical section 62. The seal 11 is filled between the third vertical section 53 and the main body 4, thereby protecting the roll waterproofing layer 32 on the second vertical section 62, thereby extending the service life of the roofing system 100.
[0073] Preferably, the sealing member 11 and the waterproof roll layer 32 are made of the same material, and the sealing member 11 and the waterproof roll layer 32 are connected by hot-melt welding. The sealing member 11 may be made of welding rope or the like.
[0074] It should be noted that the process steps and construction tools for bending and curling construction and hot melt welding operations are well known to technical personnel in this field and do not belong to the core improvement part of this application, so they will not be repeated here.
[0075] Those skilled in the art can understand that the present application is not limited to the above-mentioned double curling structure, but can also be a triple curling structure. The triple curling structure includes seven layers of curling arranged in a stacked manner, so as to achieve a tight connection of the roof panel 3. The multiple curling structure 1 including multiple layers of curling arranged in a stacked manner should fall within the protection scope of the present application.
[0076] In some embodiments, the roofing system 100 is installed on the main structure of the house, and the roofing system 100 also includes a support frame 9, the top of the support frame 9 extends upward and is limitedly matched with the multiple curling structure 1, and the bottom of the support frame 9 is connected to the main structure of the house.
[0077] Specifically, the main body 4 includes a middle section 41, a first inclined section 42, a second inclined section 43, a first edge section 44 and a second edge section 45, wherein the first inclined section 42 is connected to the left end of the middle section 41, the first edge section 44 is connected to the left end of the first inclined section 42, the second inclined section 43 is connected to the right end of the middle section 41, the second edge section 45 is connected to the right end of the second inclined section 43, the first plate edge section 5 is connected to the left end of the first edge section 44, the second plate edge section 6 is connected to the right end of the second edge section 45, the angle between the inclined section and the middle section 41 is an obtuse angle, and the first edge section 44 and the second edge section 45 both extend in the left-right direction.
[0078] Furthermore, after the adjacent roof panels 3 are connected, a trapezoidal installation groove 10 is formed at the connection. The groove of the trapezoidal installation groove 10 faces downward and is used to install the support frame 9, thereby reducing the distance between the bottom surface of the roof panel 3 and the main structure of the house, thereby preventing the roof system 100 from being blown away due to external force. Specifically, the first edge section 44 of one roof panel 3 and the second edge section 45 of another roof panel 3 are located in the same horizontal plane and serve as the bottom of the trapezoidal installation groove 10; the first inclined section 42 of one roof panel 3 and the second inclined section 43 of another roof panel 3 serve as the groove wall of the trapezoidal installation groove 10; the top of the support frame 9 extends into the multiple curling structure 1 for limited fit, and the bottom of the support frame 9 is fixedly connected to the main structure of the house.
[0079] In some embodiments, the support frame 9 includes a support portion 92 and an ear portion 91 arranged at the upper end of the support portion 92. After the ear portion 91 is connected to the double curling structure, the ear portion 91 is consistent with the bending shape of the second board edge portion 6 and is embedded between the first board edge portion 5 and the second board edge portion 6.
[0080] Specifically, the top surface of the main structure of the house is provided with a plurality of purlins 200, and the lower end of the support frame 9 is connected to the purlins 200, thereby realizing the connection between the roof system 100 and the main structure of the house.
[0081] Two types of roof panels 3 are provided in the present application. The rolled waterproof layer 32 of the first embodiment covers the entire main body 4, the first panel edge 5 and the second panel edge 6, so that the formed multi-layer rolled edges are all covered with the rolled waterproof layer 32; the second embodiment covers the entire main body 4, the first panel edge 5 and the second vertical section 62 of the second panel edge 6, but does not cover the second horizontal section 61 of the second panel edge 6, so that the formed fourth-layer rolled edge 17 is only provided with the base layer 31.
[0082] Among them, the roof system 100 formed by the roof panels 3 of the first embodiment is used for the roof structure of houses in inland areas with less wind, and the overall watertight performance of this roof system 100 is better; the roof system 100 formed by the roof panels 3 of the second embodiment is used for the roof structure of houses in coastal areas with stronger winds, and the multiple rolled edge structure 1 of this roof system 100 has higher strength.
[0083] Specifically, the waterproofing layer 32 of the fourth curling edge 17 formed by the second horizontal section 61 in the first embodiment is bonded to the base layer 31 of the fifth curling edge 18 formed by the third vertical section 53, thereby ensuring that the contact area of the waterproofing layer 32 is increased without exposing the base layer 31, thereby enhancing the waterproofing of the roofing system 100. The base layer 31 of the fourth curling edge 17 formed by the second horizontal section 61 in the second embodiment is bonded to the base layer 31 of the fifth curling edge 18 formed by the third vertical section 53, thereby ensuring that the multiple curling edge structure 1 is more compact without exposing the base layer 31, thereby enhancing the bonding strength of the multiple curling edge structure 1, and at the same time, welding ropes can be optionally added to seal the bite seam 2, thereby enhancing the airtightness of the multiple curling edge structure 1.
[0084] In some embodiments, the base layer 31 is a steel plate; and / or the waterproof roll layer 32 is a thermoplastic polyolefin (TPO) waterproof roll.
[0085] It should be noted that the base layer 31 can be made of other hard materials, such as PVC board, etc.; the waterproof roll layer 32 can be made of other waterproof roll materials, such as SBS polymer roll materials, etc., and other material parts also fall within the protection scope of this application.
[0086] In the present application, the roof system 100 is laid on the top surface of the main structure of the house to form the house roof structure, wherein the folded edges of multiple roof panels 3 are interlocked and connected as curling edges to form a multiple curling edge structure 1, and the multiple curling edge structure 1 is connected to the purlin 200 on the top surface of the main structure of the house through a support frame 9, thereby realizing the connection between the roof system 100 and the main structure of the house. The roof panel 3 includes a base layer 31 and a roll waterproof layer 32 covering the base layer 31. By laying the roof panel 3, the main roof structure and the roof waterproof structure are constructed simultaneously, thereby shortening the construction period of the house roof structure.
