Description
Technical Field
[0001] This utility model belongs to the technical field of thermal insulation roofing, and more specifically, relates to a novel thermal insulation metal roofing structure system. Background Technology
[0002] Currently, traditional metal roofs use purlins to connect supports, and then the roof panels are fixed to the supports. Therefore, there are multiple load-bearing layers. At the same time, the insulation layer is divided and interrupted by the long purlins. The construction of metal roofs involves many layers, and load transmission requires multiple transfers. Therefore, the construction is complicated, the load-bearing layers are not simple enough, and the roof instability increases the risk. Utility Model Content
[0003] In view of this, in order to solve the above-mentioned problems of the existing technology, the purpose of this utility model is to provide a new type of thermal insulation metal roof structure system, which aims to enhance the stability of roof load transmission, improve the safety of the roof, and at the same time has the advantages of simple construction and shortened construction period.
[0004] The technical solution adopted in this utility model is as follows:
[0005] A novel thermal insulation metal roofing structure system includes: a number of purlins, a base plate, a vapor barrier, a thermal insulation layer, a waterproof layer, a heat insulation layer, and a roof panel connected sequentially from bottom to top;
[0006] It also includes several brackets and several supports; the bottom of several brackets passes through the insulation layer and is connected to several purlins to press the base plate and vapor barrier membrane together; the bottom of the supports is connected to the top of the brackets to press the waterproof layer together.
[0007] In a further technical solution, the top of the bracket is flush with the insulation layer.
[0008] In a further technical solution, a plurality of heat insulation pads are also included, wherein the plurality of heat insulation pads are respectively disposed between the bracket and the support.
[0009] In a further technical solution, the top of the support has a first interlocking edge that passes through the insulation layer; the roof panel has a second interlocking edge, and the first interlocking edge and the second interlocking edge are fitted together.
[0010] In a further technical solution, the bracket is connected to the purlin via self-tapping screws; the support is connected to the bracket via self-tapping screws.
[0011] In a further technical solution, the bracket is a high-profile steel bracket, and the support is an aluminum alloy support.
[0012] In a further technical solution, the purlin is a rigid secondary purlin.
[0013] In a further technical solution, the insulation layer is made of hydrophobic rock wool.
[0014] In a further technical solution, the heat insulation layer is made of glass wool.
[0015] In a further technical solution, the waterproof layer is made of thermoplastic polyolefins.
[0016] The working principle and beneficial effects of this utility model are as follows:
[0017] The supports are directly connected to the brackets, allowing external roof loads and the roof's own loads to be directly transferred to the brackets, then to the purlins, and finally to the main building structure, forming a stable force transmission guide. This eliminates the need for purlin transitions, reducing the number of layers in the force transmission structure and improving the stability of the roof structure. Furthermore, the absence of traditional purlins simplifies the roof's structural layers, preventing the insulation layer from being interrupted and improving overall insulation continuity. The connection between the supports and brackets eliminates the need for purlin transitions, simplifying construction, shortening the construction period, and facilitating project management.

[0029] Example 1
[0030] Please refer to Figures 1-4 A novel thermal insulation metal roofing structure system includes several purlins 1, several brackets 2, several supports 10, several thermal insulation pads 11, a base plate 4, a vapor barrier 5, a thermal insulation layer 6, a waterproof layer 7, a thermal insulation layer 8, and a roof panel 9.
[0031] like Figures 1-4 As shown, several purlins 1, base plate 4, vapor barrier 5, insulation layer 6, waterproof layer 7, heat insulation layer 8 and roof panel 9 are connected sequentially from bottom to top. The base plate 4 supports the multiple layers of materials on top of it. The bottom of several brackets 2 passes through the insulation layer 6 and is connected to several purlins 1 by self-tapping screws 3, pressing the base plate 4 and vapor barrier 5 tightly onto the purlins 1. The top of the brackets 2 is flush with the top of the insulation layer 6.
[0032] The roof panel 9 prevents water from seeping into the building, serving as the first layer of waterproofing; the insulation layer 8 blocks heat transfer and eliminates adverse effects such as adhesion, mechanical bonding, and chemical reactions between adjacent materials, namely the waterproof layer below the insulation layer and the roof panel above it; the waterproof layer 7 prevents water from seeping into the building, serving as the second layer of waterproofing; the thermal insulation layer 6 reduces heat exchange and provides insulation; the vapor barrier 5 prevents indoor water vapor from penetrating into the thermal insulation layer 6.
[0033] The bottom of several supports 10 is connected to the top of the bracket 2 by self-drilling screws 3, thereby pressing the waterproof layer 7 onto the top of the insulation layer 6; the top of several supports 10 has a first interlocking edge 10a, which extends through the insulation layer 8 to the outside, and the roof panel 9 has a second interlocking edge 9a. The roof panel 9 is laid on the top of the insulation layer 8 and is tightly attached to the first interlocking edge 10a of the top of the supports 10 through the second interlocking edge 9a.
[0034] The support 10 is connected to the bracket 2 via stainless steel self-tapping screws 3, eliminating the need for traditional purlins 1 and simplifying the number of layers in the insulated metal roof structure; simultaneously, the support 10 and the bracket 2 are connected via self-tapping screws 3.
[0035] The external load and its own load of the roof are directly transmitted to the support 2. Similarly, the support 2 transmits the upper load and its own load directly to the purlin 1 through the stainless steel self-tapping screws 3, and then to the main structure of the building, forming a stable force transmission guide. Without the conversion of the purlin 1, the force transmission structure system is reduced by one layer, and the stability of the roof structure system is improved.
[0036] The support 10 and bracket 2 are directly connected without the need for the conversion of the purlin 1. The insulation layer 6 is not interrupted, resulting in better overall insulation continuity. Furthermore, the absence of the purlin 1 conversion simplifies construction, shortens the construction period, and facilitates project management.
[0037] like Figure 3 As shown, several heat insulation pads 11 are respectively disposed between the bracket 2 and the support 10; the heat insulation pads 11 can reduce the transfer of outdoor solar radiation heat to the bracket 2 through the support 10, and at the same time block the electrochemical corrosion between the support 10 and the bracket 2.
[0038] In this embodiment, the frame is a high-profile steel support frame 2.
[0039] In this embodiment, the support 10 is an aluminum alloy support 10.
[0040] In this embodiment, purlin 1 is a secondary purlin 1.
[0041] In this embodiment, the insulation layer 6 is made of hydrophobic rock wool.
[0042] In this embodiment, the heat insulation layer 8 is made of glass wool.
[0043] In this embodiment, the waterproof layer 7 is made of thermoplastic polyolefin.
[0044] In this embodiment, the base plate 4 is a profiled roof steel base plate 4.
[0045] In this embodiment, the heat insulation pad 11 is made of rubber.
[0046] In this embodiment, the roof panel 9 is an aluminum-magnesium-manganese roof panel 9.
[0047] In this embodiment, the self-tapping and self-drilling screw 3 is made of stainless steel.
[0048] In this embodiment, the vapor barrier 5 is made of polypropylene plastic. This invention is not limited to the above-described optional embodiments; anyone inspired by this invention can derive various other forms of the product. However, regardless of any changes in shape or structure, any technical solution falling within the scope of the claims of this invention is protected by this invention.
