Abstract
Description
Technical Field
[0001] This application relates to the field of roof structure technology, specifically to a lightweight, thermally insulated planar roof structure. Background Technology
[0002] In winter, outdoor temperatures are low, and ordinary concrete roofs have a high thermal conductivity, which makes them ineffective at blocking heat exchange, resulting in a lower indoor temperature as well.
[0003] For flat roof insulation, lightweight, porous insulation materials with low thermal conductivity should generally be selected. Flat roof insulation typically involves laying multiple layers on the roof structure, including a leveling layer, a waterproof layer, an insulation layer, an isolation layer, and a protective layer. This results in a heavy insulated roof that is difficult to maintain. Utility Model Content
[0004] Given that the common method of achieving thermal insulation on flat roofs involves laying multiple layers on the roof structure, which results in a heavy insulated roof that is difficult to maintain, this application proposes the following technical solution.
[0005] A lightweight, insulated planar roof structure includes a structural layer, an insulation layer, and a water-conducting layer.
[0006] The insulation layer is laid on the structural layer and does not cover a set of opposite side areas of the structural layer.
[0007] A drainage outlet is provided on each pair of opposite sides of the structural layer that are not covered by the insulation layer.
[0008] The water-guiding layer is laid on the insulation layer and on a set of opposite side areas of the structural layer not covered by the insulation layer, and the water-guiding layer is configured to direct water flow to the drain outlet.
[0009] By adopting the above technical solution, the lightweight insulated flat roof structure only lays an insulation layer and a water-conducting layer on the roof structure layer, so that the roof is insulated. The roof is lightweight and easy to construct and maintain.
[0010] A preferred embodiment of this lightweight, insulated planar roof structure is that the insulation layer comprises multiple strips of insulation cotton, arranged parallel to each other and aligned at both ends. A set of opposite side areas of the structural layer not covered by the multiple strips of insulation cotton are rectangular slots. The drainage outlet is located at the bottom of these slots.
[0011] By adopting the above technical solutions, the insulation cotton is lightweight and has good insulation effect, and is easy to lay, construct and maintain.
[0012] A preferred embodiment of this lightweight, insulated planar roof structure includes a water-guiding layer comprising multiple unit panels and two drainage boxes. Each unit panel comprises a first vertical panel, a lower horizontal panel, a second vertical panel, an upper shield, and a third vertical panel, all arranged longitudinally. The first vertical panel, the lower horizontal panel, the second vertical panel, the upper shield, and the third vertical panel are sequentially and seamlessly connected laterally. The first vertical panel, the lower horizontal panel, and the second vertical panel form an upward-opening water collection trough. The second vertical panel, the upper shield, and the third vertical panel form a downward-opening rain-shielding mechanism. Except for the last unit panel, the rain-shielding mechanism of each unit panel is fitted onto the first vertical panel of the adjacent unit panel.
[0013] The multiple unit panels are mounted on the insulation layer. Two drainage boxes are installed in the two empty slots. The two drainage boxes close the two ports of each rainproof mechanism and connect to the two ports of each water collection tank. The drainage boxes are connected to the drain outlet.
[0014] By adopting the above technical solution, the unit panels are horizontally and continuously spliced, with complete coverage from above, making it difficult for rainwater to penetrate into the insulation layer from above. The drainage boxes on both sides cover the two ends of the insulation layer, preventing rainwater from penetrating the insulation layer from the sides. The connected and spliced unit panels collect rainwater and guide it to the two drainage boxes, which then direct the water to the drain outlet for discharge.
[0015] In a preferred embodiment of the lightweight insulated planar roof structure, each of the unit panels and each of the drainage boxes is made of resin.
[0016] By adopting the above technical solution, the resin material is lightweight, has good waterproof effect, and is easy to construct and maintain. This makes the water-conducting layer composed of unit boards and drainage boxes lightweight and easy to install and maintain.
[0017] A preferred embodiment of this lightweight, insulated planar roof structure is that the inner side of the drainage box has a main vertical plate and multiple upright plates on the same vertical plane. The multiple upright plates are integrally formed on the upper edge of the main vertical plate.
[0018] Each of the vertical panels seals over one port of the rain-shielding mechanism. The main vertical panel seamlessly fits the end face of each of the lower horizontal panels and seals over the end face of the insulation layer. The upper edge of the main vertical panel is flush with the upper surface of the lower horizontal panel.
[0019] By adopting the above technical solution, the drainage box not only seals the non-drainage openings at the high position on the side of the sequentially connected unit plates, but also effectively receives the water flowing out from the drainage openings at the low position on the side of the unit plates and discharges it outward.
[0020] In a preferred embodiment of this lightweight, insulated planar roof structure, the upper cover is a flat panel. The vertical panels are rectangular strips, adapted to fit the end faces of the second vertical panel, the upper cover, and the third vertical panel.
[0021] By adopting the above technical solution, each upright plate fits and seals the side opening of a rain shelter mechanism, providing good sealing and effectively preventing rainwater from seeping into the interior of the rain shelter mechanism.
[0022] In a preferred embodiment of this lightweight, insulated planar roof structure, the lower surface of the third vertical plate of one unit panel is attached to the lower horizontal plate of the adjacent unit panel. The lower horizontal plates of each unit panel are horizontally aligned.
[0023] By adopting the above technical solution, adjacent unit panels can be connected flush, with small gaps at the connection. Multiple unit panels can be connected to form a waterproof structure of equal height and flush, which can effectively prevent rainwater from splashing into the insulation layer after falling.
[0024] A preferred embodiment of the lightweight, insulated planar roof structure is that the first vertical plate, the lower horizontal plate, the second vertical plate, the upper shielding plate, and the third vertical plate are integrally formed.
[0025] By adopting the above technical solution, the unit panel is integrally molded, which is easy to manufacture and has a better effect in preventing rainwater leakage.
[0026] A preferred embodiment of the lightweight insulated flat roof structure includes a parapet wall, which is arranged around the upper surface of the structural layer. The first vertical plate of the first unit panel seamlessly fits the inner wall of the parapet wall, and the third vertical plate of the last unit panel seamlessly fits the inner wall of the parapet wall. The outer side of each drainage box seamlessly fits the inner wall of the parapet wall. Both end faces of each drainage box seamlessly fit the inner wall of the parapet wall, one end face of each drainage box seamlessly connects to the first vertical plate of the first unit panel, and the other end face of each drainage box seamlessly connects to the third vertical plate of the last unit panel.
[0027] By adopting the above technical solution, the top of the structural layer is completely seamlessly covered, and rainwater is not easy to penetrate into the insulation layer and structural layer. Rainwater can be collected by the water-conducting layer and directed to the drainage outlet to be discharged from the roof.
[0028] In a preferred embodiment of this lightweight, insulated planar roof structure, the first vertical plate of the first unit panel, the third vertical plate of the last unit panel, and the outer and end faces of each drainage box are seamlessly attached to the parapet wall using waterproof adhesive. One end face of each drainage box is seamlessly joined to the first vertical plate of the first unit panel using waterproof adhesive, and the other end face of each drainage box is seamlessly joined to the third vertical plate of the last unit panel using waterproof adhesive.
[0029] By adopting the above technical solution, the waterproof adhesive can effectively prevent rainwater leakage, allowing the water-conducting layer to effectively prevent rainwater from seeping downwards and to the sides, thus effectively protecting the insulation layer and structural layer.
[0030] In summary, the lightweight insulated flat roof structure of this application has the following beneficial effects: by laying insulation cotton and water-conducting layer only on the structural layer, the overall weight of the roof is reduced, achieving lightweight insulated roof, reducing the load pressure on the main building structure, and the flat roof structure is easy to construct and maintain.

[0038] The technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the following embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0039] like Figure 1 A lightweight, insulated planar roof structure includes a structural layer 1 and an insulation layer 2 on top of the structural layer 1. A drainage outlet 11 is provided on each side of the structural layer. The insulation layer 2 does not cover two opposite sides of the structural layer 1, leaving rectangular grooves 12 on each of the two opposite sides. The drainage outlet 11 is located at the bottom of one end of the groove 12.
[0040] The insulation layer 2 is composed of multiple parallel strips of insulation cotton 21, with the two ends of each strip aligned, thus leaving slots 12 on two opposite sides of the structural layer 1. The insulation cotton 21 can be a roll material, which unfolds into a rectangular strip.
[0041] The lightweight insulated flat roof structure also includes a parapet wall 4, which stands upright around the upper surface of the structural layer 1. The insulation layer 2 is located inside the parapet wall 4.
[0042] like Figure 2 The lightweight insulated flat roof structure also includes a water-guiding layer 3. This water-guiding layer 3 comprises multiple unit panels 31 and two drainage boxes 32. Both the unit panels 31 and the drainage boxes 32 are made of resin, which is lightweight, has good waterproofing properties, and is easy to install and maintain. Multiple unit panels 31 cover the insulation layer 2. The length of the unit panels 31 is equal to the length of the insulation cotton 21, while their widths may be equal or unequal. The two drainage boxes 32 are installed in two empty slots 12. The drainage boxes 32 connect to the drainage outlets 11 below. This water-guiding layer 3 is located inside the parapet wall 4.
[0043] like Figure 3 Each unit plate 31 includes a first vertical plate 311, a lower horizontal plate 312, a second vertical plate 313, an upper cover plate 314, and a third vertical plate 315, all arranged longitudinally. The first vertical plate 311, the lower horizontal plate 312, the second vertical plate 313, the upper cover plate 314, and the third vertical plate 315 are sequentially connected laterally and integrally formed. The unit plate 31 can be made of resin material, and in some embodiments, the unit plate 31 can also be made of sheet metal, etc.
[0044] The first vertical plate 311, the lower horizontal plate 312, and the second vertical plate 313 form an upward-opening water collection trough 316, used to collect and collect rainwater, which is then directed from both ends to the drainage box 32, and then from the drainage box 32 to the drain outlet 11 for discharge. The second vertical plate 313, the upper cover plate 314, and the third vertical plate 315 form a downward-opening rain-proof mechanism 317, used to cover the first vertical plate 311 of adjacent unit plates 31. In this way, multiple unit plates 31 are horizontally continuous, and there are no gaps on the upper surface for rainwater to seep in. Rainwater falling on the rain-proof mechanism 317 is directed to both sides to the two water collection troughs 316. The rainwater collected in each water collection trough 316 flows out from both ends into the drainage box 32, and finally flows to the drain outlet 11 to be discharged from the roof. The above structure effectively prevents rainwater from contaminating the insulation layer 2.
[0045] like Figure 4 Generally, the splicing method of adjacent unit panels 31 is as follows: the rain-shielding mechanism 317 of the left unit panel 31 covers the first vertical plate 311 of the right unit panel 31. Preferably, it is a shape-adaptive cover. For example, the second vertical plate 313 is parallel to the third vertical plate 315, and the distance between the second vertical plate 313 and the third vertical plate 315 is equal to the thickness of the first vertical plate 311. The upper cover 314 is a flat plate, and the upper cover 314 is attached to the upper surface of the first vertical plate 311. The lower surface of the third vertical plate 315 on the left side is attached to the upper surface of the lower horizontal plate 312 on the right side, thus completing the adaptation and coverage of the rain-shielding mechanism 317 of the left unit panel 31 to the first vertical plate 311 of the right unit panel 31. After this adaptation and coverage, rainwater is less likely to splash into the rain-shielding mechanism 317 and infiltrate the insulation cotton 21.
[0046] The above describes the splicing method of adjacent unit panels 31. However, since there is no unit panel 31 on the right side of the last unit panel 31, the rainproof mechanism 317 of the last unit panel 31 is attached to the inner wall of the parapet wall, that is, the third vertical panel 315 is attached to the inner wall of the parapet wall. Waterproof adhesive can be used to attach them to prevent rainwater from seeping into the insulation layer 2 and the structural layer 1.
[0047] The above lightweight insulated flat roof structure only lays an insulation layer 2 and a water-conducting layer 3 on the roof structure layer 1. It has good insulation effect, light weight, and is easy to construct and maintain.
[0048] To prevent rainwater from seeping into structural layer 1 and insulation layer 2, in addition to the above-mentioned design that the various parts of the water-guiding layer 3 can prevent rainwater leakage after being spliced together, the four sides of the water-guiding layer 3 must also be designed to completely fit the inner wall of the parapet wall 4 to prevent rainwater leakage. For example, the first unit panel 31, i.e., from... Figure 2 See, for the leftmost unit panel 31, the first vertical plate 311 of this first unit panel 31 seamlessly fits the longitudinal inner wall of the parapet wall 4, and the third vertical plate 315 of the last unit panel 31 seamlessly fits the longitudinal inner wall of the parapet wall 4 on the opposite side. (Reference) Figure 5Each drainage box 32 has its outer surface 322 seamlessly attached to the transverse inner wall of the parapet wall 4. The two end faces of each drainage box 32 are also seamlessly attached to the longitudinal inner wall of the parapet wall 4: on the left side, one end face of each drainage box 32 is seamlessly spliced to both sides of the first vertical plate 311 of the first unit panel 31; on the right side, the other end face of each drainage box 32 is seamlessly spliced to both sides of the third vertical plate 315 of the last unit panel 31. After these attachments and splices, all unit panels 31 and drainage boxes 32 form a seamlessly closed water-guiding layer 3, and the four outer perimeters of this water-guiding layer are seamlessly attached to the four inner walls of the parapet wall 4, making the water-guiding layer essentially gapless downwards, preventing rainwater from seeping downwards. This provides good waterproof protection for the underlying insulation layer 2 and structural layer 1.
[0049] To achieve seamless splicing of unit panels 31 and drainage boxes 32, and seamless bonding of the water-conducting layer 3 and parapet wall 4, one construction method is as follows: the first vertical plate 311 of the first unit panel 31, the third vertical plate 315 of the last unit panel 31, the outer side 322 and both end faces of each drainage box 32 are seamlessly bonded to the parapet wall 4 using waterproof adhesive. One end face of the two drainage boxes 32 is seamlessly spliced to the first vertical plate 311 of the first unit panel 31 using waterproof adhesive, and the other end face of the two drainage boxes 32 is seamlessly spliced to the third vertical plate 315 of the last unit panel 31 using waterproof adhesive. The waterproof adhesive has good water immersion resistance and can still effectively prevent rainwater leakage even after long-term use.
[0050] It should be noted that the end face mentioned in the embodiments generally refers to the two ends of a long strip-shaped object, and the port generally refers to the two ends of the long strip-shaped groove.
[0051] Continue to refer Figure 5 For the drainage box 32, it should be able to seal the port of the rainproof mechanism 317 and smoothly receive the water flowing out of the water collection tank 316. Therefore, the inner side 321 of the drainage box 32 is designed to have a vertical main plate 3211 and multiple upright plates 3212 on the same side. The multiple upright plates 3212 are integrally formed on the upper edge of the vertical main plate 3211. The height of the outer side 322 of the drainage box 32 can be greater than the sum of the heights of the vertical main plate 3211 and the upright plates 3212. The heights of the front end face 323 and the rear end face 324 of the drainage box 32 can be equal to the height of the outer side 322. The bottom surface of the drainage box 32 is seamlessly connected to the inner side 321, the outer side 322, the front end face 323, and the rear end face 324.
[0052] like Figure 6Each vertical panel 3212 is sealed to cover one port of a rain shelter mechanism 317. The main vertical panel 3211 seamlessly fits the end face of each lower horizontal panel 312 and seals to cover the end face of the insulation layer 2. The upper edge of the main vertical panel 3211 is flush with the upper surface of the lower horizontal panel 312. The drainage box 32 of this structure not only seals the non-drainage openings at the high position on the side of the sequentially connected unit panels 31, but also smoothly receives water flowing out of the openings at the low position on the side of the unit panels 31, and guides the water to the drain outlet 11 to be discharged from the roof.
[0053] In the aforementioned embodiment, the upper shield 314 is designed as a flat plate. In order to make the spliced water-guiding layer 3 flat and firm, the following embodiment is designed as a square strip for the vertical plate 3212, which fits the end face of the second vertical plate 313, the end face of the upper shield 314 and the end face of the third vertical plate 315. That is, each vertical plate 3212 closes one port of a rain shelter mechanism 317 to prevent rainwater from seeping into the interior of the rain shelter mechanism 317.
[0054] In addition to being a flat plate, the upper cover 314 can also be an arc plate, which connects the second vertical plate 313 and the third vertical plate 315. The top of the vertical plate 3212 is also arc-shaped, and the vertical plate 3212 can fit snugly against the end face of the upper cover 314 to prevent rainwater from seeping into the port of the rain shelter mechanism 317.
[0055] The lightweight insulated flat roof structure in the above embodiment only lays insulation cotton 21 and water-conducting layer 3 on the structural layer 1, which reduces the overall weight of the insulated roof and reduces the load pressure on the main building structure. At the same time, the structure is also easy to construct and maintain.
[0056] Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
