Description

Technical Field

[0001] This utility model relates to an energy-saving and waterproof metal roof, belonging to the field of building construction technology. Background Technology

[0002] With the continuous development of the construction industry and the increasing energy consumption of buildings, the problem of building energy consumption is becoming more and more prominent. In view of the shortcomings of traditional materials and technologies in building energy conservation and waterproofing, seeking new materials, technologies and application systems has become an important aspect of building energy conservation research.

[0003] Metal roofs are a common building structure type in public and industrial buildings. However, the heat transfer coefficient of certain parts of a metal roof is significantly higher than that of other parts, causing heat to be concentrated and rapidly transferred from these areas, resulting in severe thermal bridging. Thermal bridging significantly increases building energy consumption, can lead to condensation, and causes corrosion and damage, severely disrupting normal production and daily life within the building.

[0004] Secondly, in traditional roof waterproofing solutions, the problem of perforations in the waterproof membrane is addressed by applying sealant. However, this method does not fundamentally solve the problem. If the sealant is not applied properly during construction, leaks will still occur. Furthermore, over time, as the adhesive ages, the gaps around the screw holes widen, significantly reducing the waterproofing effectiveness. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide an energy-saving and waterproof metal roof that solves the common leakage problem of traditional metal roofs, reduces the thermal bridging effect of the roof, extends the service life of the roof, and reduces the later maintenance cost.

[0006] The present invention discloses an energy-saving and waterproof metal roof, comprising several purlins installed on a steel structure building, a profiled steel sheet laid on top of the purlins, a vapor barrier membrane laid on the profiled steel sheet, insulation cotton laid on top of the vapor barrier membrane, a waterproof membrane installed on top of the insulation cotton, several roof panels laid on top of the waterproof membrane, supports set between adjacent roof panels, anti-cold bridge supports set inside the insulation cotton, and the bottom of the anti-cold bridge supports connected to the profiled steel sheet by self-tapping screws; an integrated waterproof disc is set between the anti-cold bridge supports and the roof panels, and the integrated waterproof disc and the waterproof membrane are located on the same layer;

[0007] The waterproof integrated disc includes a flange with self-tapping bolts at the bottom. The flange is connected to the top of the anti-cold bridge support via the self-tapping bolts, and machine thread bolts are installed at the top of the flange.

[0008] The flange is made of steel as the base material, wrapped with a polymer material. The polymer material and steel are tightly bonded together. A waterproof skirt is provided around the outer perimeter of the flange, and the waterproof skirt is welded to the waterproof membrane using hot air welding. The lower end of the integrated waterproof disc is fixed to the anti-cold bridge support. The integrated polymer flange is tightly bonded to the waterproof membrane by hot air welding or self-adhesion, effectively preventing leakage caused by nail holes and ensuring the sealing and consistency of the roof waterproofing.

[0009] The flange is made of steel plate, and two machine-threaded screws are placed at the top of the flange. Steel plate possesses high strength, high toughness, and good corrosion resistance, enabling it to withstand significant mechanical stress and environmental impacts. As the material for the flange, steel plate effectively ensures the firmness and stability of the connection, extending its service life. The two machine-threaded screws at the top of the flange provide a more reliable fixing effect compared to a single-screw connection. The two screws distribute the force, reducing the load on a single screw and thus minimizing the risk of connection failure due to screw loosening or breakage.

[0010] A support riser is installed on the flange, and the support riser is locked to the flange by machine bolts. The support riser usually has a circular cross-section, which has high bending and torsional resistance in terms of mechanical properties, and can effectively bear the weight of the roof panel and external loads, such as wind loads and snow loads, thereby providing stable support for the roof system.

[0011] The height of the aforementioned anti-cold bridge support is 50mm-150mm. Through insulation materials and a reasonable structural design, the anti-cold bridge support can effectively block heat conduction within the building structure. Within a height range of 50mm-150mm, the support can effectively isolate the thermal bridging effect, reduce heat loss, and lower energy consumption.

[0012] The thickness of the waterproof membrane is 1mm-5mm. Waterproof membranes with a thickness in the range of 1mm-5mm, especially thicker membranes, have stronger puncture resistance, abrasion resistance, and aging resistance. This allows the membrane to better resist the erosion of the natural environment during long-term use, extending its service life.

[0013] The insulation layer includes glass wool, rock wool, foam glass, and graphite polystyrene board. Glass wool is a fibrous insulation material with low thermal conductivity, good sound absorption, and high chemical stability. Its fibrous structure effectively blocks heat transfer while absorbing noise, improving the building's sound insulation. Rock wool board, also known as rock wool insulation decorative board, is an inorganic fiber board made primarily from basalt through high-temperature melting. Rock wool is lightweight, has low thermal conductivity, absorbs heat, and is non-combustible. Foam glass is an inorganic insulation material with low thermal conductivity, and features non-combustibility, low water absorption, and strong weather resistance. Its closed-cell structure effectively prevents moisture penetration, making it suitable for humid environments. Graphite polystyrene board is a modified polystyrene foam plastic with a closed-cell structure, low thermal conductivity, and good fire resistance, classifying it as a B1-grade flame-retardant material. Its graphite particles reflect heat radiation, further enhancing the insulation effect.

[0014] A U-shaped connector is installed between the vapor barrier and the insulation cotton, corresponding to the purlins. The bottom of the anti-cold bridge support is fixed to the U-shaped connector using self-tapping screws. The anti-cold bridge support includes an upper connector, a heat insulation component, and a lower connector, with the heat insulation component positioned between the upper and lower connectors. The heat insulation component effectively blocks heat conduction between the upper and lower connectors, thereby reducing the cold bridge effect and heat loss. This structural design facilitates installation and maintenance, while the heat insulation component effectively isolates heat conduction. Another type of anti-cold bridge support structure involves covering the middle of the U-shaped steel plate with heat insulation material, and the steel plate at the heat insulation material covering position has a through-hole structure.

[0015] The insulation component is made of polymer material, while the upper and lower connectors are made of metal. Polymer materials have low thermal conductivity, effectively blocking heat conduction and reducing heat transfer through the connectors, thus mitigating the cold bridging effect. This design significantly improves the building's insulation performance and reduces heat loss. The upper and lower connectors are made of metal, possessing high strength and good mechanical properties, capable of withstanding significant loads and external impacts. This design ensures the stability and reliability of the support during use.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] By sequentially laying vapor barrier membrane, thermal insulation cotton, and waterproof membrane on profiled steel sheets, and installing supports between the roof panels, a multi-layered sealed structure is formed, effectively preventing moisture penetration and solving the common leakage problems of traditional metal roofs. This roofing system, through the rational design of the thermal insulation cotton and vapor barrier membrane, effectively reduces heat transfer and lowers the building's energy consumption. The anti-cold bridge support works in conjunction with the integrated waterproof disc; during installation, the contact point between the support and the purlin changes from metal-to-metal to non-metal-to-metal, effectively reducing the heat conduction rate, indirectly increasing thermal resistance, and reducing the thermal bridging effect on the roof. The anti-cold bridge support is fixed to the roof with self-tapping screws and Z-shaped connectors, while the integrated waterproof disc is connected to the anti-cold bridge support and the support frame with self-tapping bolts and machine thread bolts respectively. This structural design enhances the overall stability of the roof. Through multi-layered protection and sealing design, the erosion of the roof structure by the external environment is reduced, thereby extending the roof's service life and reducing later maintenance costs.

[0024] The present invention will be further described below with reference to embodiments:

[0025] Example 1

[0026] like Figure 1 and Figure 3As shown, the energy-saving and waterproof metal roof of this utility model includes several purlins 1 installed on the building. A profiled steel sheet 2 is laid on the top of the purlins 1. A vapor barrier membrane is laid on the profiled steel sheet 2. Insulation cotton 3 is laid on the top of the vapor barrier membrane. A waterproof membrane 4 is installed on the top of the insulation cotton 3. Several roof panels 5 are laid on the top of the waterproof membrane 4. A bracket 6 is set between adjacent roof panels 5. The bracket 6 is slidably connected to the roof panel 5. A Z-shaped connector 9 is set between the vapor barrier membrane and the insulation cotton 3 corresponding to the purlins 1. A cold bridge support 8 is set on the top of the Z-shaped connector 9 inside the insulation cotton 3. The bottom of the cold bridge support 8 is fixed to the Z-shaped connector 9 by self-tapping screws. A waterproof integrated disc 7 is set between the cold bridge support 8 and the roof panel 5.

[0027] The integrated waterproof disc 7 includes a flange 72, with self-tapping bolts at its bottom. The flange 72 is connected to the top of the anti-cold bridge support 8 via these bolts. A machine-threaded bolt 71 is installed at the top of the flange 72, connecting it to the riser via the machine-threaded bolt 71. The flange 72 is made of polymer material and is hot-air welded to the waterproof membrane 4. The height of the anti-cold bridge support 8 is 50mm, 100mm, or 150mm. The thickness of the waterproof membrane 4 is 1mm, 2.5mm, or 5mm. The insulation layer includes glass wool, foam glass, and graphite polystyrene board. The anti-cold bridge support 8 includes an upper connector 81, a thermal insulation component 82, and a lower connector 83, with the thermal insulation component 82 positioned between the upper connector 81 and the lower connector 83. The thermal insulation component 82 is made of polymer material, while the upper connector 81 and the lower connector 83 are made of metal. The anti-cold bridge support 8, used in conjunction with the insulation cotton 3, effectively isolates the heat transfer between the purlin 1 and the roof panel 5, reducing roof energy consumption. The insulation component 82 is made of polymer material, which also plays a role in noise reduction. Combined with the waterproof integrated disc 7 above, it solves the problem of nail leakage, giving the building a green, energy-saving, emission-reducing, seepage-proof, and noise-reducing effect, and improving the practicality of the system.

[0028] Example 2

[0029] The difference from Embodiment 1 is that bracket 6 is an aluminum T-bracket, which is used to fit the standing seam roof panel, such as... Figure 2 As shown.

[0030] Example 3

[0031] The difference from Embodiment 1 is that a bracket 6 is installed on the anti-cold bridge support 8, allowing photovoltaic panels 11 to be installed on the roof. The photovoltaic panels 11 are connected to the roof panel 5 via wind-resistant clips, effectively solving the thermal bridging problem on the roof. Figure 4 As shown.

[0032] Example 4

[0033] The difference from Embodiment 1 is that the base material of flange 72 is steel plate, and the number of machine threaded bolts at the top of flange 72 is two. A support vertical pipe is installed on flange 72, and the support vertical pipe is locked to flange 72 by machine threaded bolts 71. Replacing the traditional method of extending through the roof columns, this not only saves building space and construction costs, but also effectively solves the problems of thermal bridging and nail hole leakage in the roof.
