Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a double-layer roof connection structure. Background Technology

[0002] With the high-quality development of the national construction industry, double-layer metal roofing systems are widely used in light steel structure public buildings due to their aesthetic appeal and waterproofing properties. A double-layer metal roofing system typically consists of an inner metal roof and an outer curtain wall attached to the outside of the inner metal roof, with a waterproof membrane installed between the inner metal roof and the outer curtain wall.

[0003] During the installation of the double-layer metal roofing system on the steel structure, the outer curtain wall usually needs to be connected to the steel structure through steel columns welded to the purlins of the inner metal roof. The connection nodes between the steel columns and the steel structure will pass through the inner metal roof, damaging the original complete waterproof structure of the double-layer metal roofing system and making it impossible to guarantee the overall waterproof performance of the roof. Utility Model Content

The third clamp is used to clamp the upper end of the stainless steel plate sleeve to the outer circumference of the steel pipe column. The fourth clamp is sleeved on the lower middle part of the stainless steel plate sleeve. The fourth clamp is used to tighten the stainless steel plate sleeve, the upper waterproof membrane sleeve and the lower waterproof membrane sleeve together onto the steel pipe column.

[0013] According to the present invention, a double-layer roof connection structure is provided, wherein the lower end of the lower waterproof membrane sleeve is welded to the roof waterproof membrane.

[0014] According to the present invention, a double-layer roof connection structure is provided, wherein the lower end of the upper waterproof membrane sleeve is welded to the roof waterproof membrane, and the weld formed by the lower end of the lower waterproof membrane sleeve and the roof waterproof membrane is staggered from the weld formed by the lower end of the upper waterproof membrane sleeve and the roof waterproof membrane.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0031] The following is combined with Figure 1The double-layer roof connection structure provided by the present invention will be described in detail through specific embodiments and application scenarios.

[0032] In this embodiment of the utility model, the double-layer roof connection structure 1 includes a steel pipe column 10, a lower waterproof membrane sleeve 20, an upper waterproof membrane sleeve 30, and a stainless steel plate sleeve 40. The steel pipe column 10 is connected between the bottom steel plate and the outer decorative panel. The lower waterproof membrane sleeve 20 is fitted onto the steel pipe column 10, and the lower end of the lower waterproof membrane sleeve 20 covers the opening end of the upper roof waterproof membrane 2 on the bottom steel plate corresponding to the steel pipe column 10. The upper waterproof membrane sleeve 30 is fitted onto the outside of the lower waterproof membrane sleeve 20, and the upper and lower ends of the upper waterproof membrane sleeve 30 cover the upper and lower ends of the lower waterproof membrane sleeve 20 inside it. The stainless steel plate sleeve 40 is fitted onto the outside of the upper waterproof membrane sleeve 30, and the upper and lower ends of the stainless steel plate sleeve 40 cover the upper and lower ends of the upper waterproof membrane sleeve 30 inside it.

[0033] The steel pipe column 10 serves as the basic support structure for the connection structure, providing solid support for the installation of the entire outer decorative panel onto the underlying steel plate. Optionally, the cross-section of the steel pipe column 10 can be any one of circular, square, prismatic, or triangular shapes, etc., without any special limitation.

[0034] The lower end of the lower waterproof membrane sleeve 20 is fitted inside the open end of the roof waterproof membrane 2 corresponding to the steel pipe column 10, and a sealed connection is established with the roof waterproof membrane 2. This design effectively prevents rainwater from seeping into the roof from the junction of the steel pipe column 10 and the roof waterproof membrane 2, ensuring the integrity of the roof waterproofing system. The sealed connection creates a tight seal between the lower waterproof membrane sleeve 20 and the roof waterproof membrane 2, enhancing the waterproofing effect.

[0035] The upper waterproof membrane sleeve 30 and the lower waterproof membrane sleeve 20 work together to form a multi-layered waterproof barrier, further enhancing the waterproof performance.

[0036] Stainless steel sleeve 40 serves as the outermost protective layer, covering the outside of all waterproof sleeves. Its main function is to protect the inner waterproof membrane sleeves from mechanical damage. On steeply pitched roofs, the waterproof layer is susceptible to physical damage due to construction, maintenance, or external factors (such as hail, human impact, etc.). Stainless steel, with its excellent impact resistance and abrasion resistance, provides a robust barrier for the waterproof layer.

[0037] This application employs a double-layer waterproofing protection system using a lower waterproof membrane sleeve 20 and an upper waterproof membrane sleeve 30. Both layers are prefabricated and welded with staggered joints. The upward tilt of the facade termination is also staggered, creating multiple tight waterproof layers at the openings of the roof waterproof membrane 2 corresponding to the steel pipe columns 10. Simultaneously, a stainless steel sleeve 40 serves as the outermost protective layer, covering all the waterproof membrane sleeves to protect the inner waterproof membrane sleeves from mechanical damage. This prevents physical damage to the waterproof layer due to construction, maintenance, or external factors (such as hail or human impact), providing a robust barrier for the waterproof layer. Thus, the use of multiple layers of waterproof membrane and a stainless steel protective layer significantly improves the waterproofing performance and reliability of the entire roof system.

[0038] Reference Figure 1 According to the double-layer roof connection structure 1 provided by this utility model, it also includes a first clamp 50, which is used to clamp the upper end of the lower waterproof membrane sleeve 20 to the outer circumference of the steel pipe column 10.

[0039] Understandably, the primary function of the first clamp 50 is to securely fasten the upper end of the lower waterproof membrane sleeve 20 to the outer circumference of the steel pipe column 10. This prevents displacement or loosening of the lower waterproof membrane sleeve 20 during construction and use. Through the tightening action of the first clamp 50, the lower waterproof membrane sleeve 20 can fit tightly against the steel pipe column 10, ensuring its stability within the entire roofing system and providing a solid foundation for subsequent waterproofing layer installation. Simultaneously, by tightening the clamp, the first clamp 50 ensures a tight fit between the contact surfaces of the lower waterproof membrane sleeve 20 and the steel pipe column 10, thereby reducing the possibility of rainwater penetration and further enhancing the waterproofing performance of the entire roofing system.

[0040] Reference Figure 1 According to the present invention, a double-layer roof connection structure 1 is provided, which also includes a second clamp 60. The second clamp 60 is used to clamp the upper end of the upper waterproof membrane sleeve 30 to the outer circumference of the steel pipe column 10.

[0041] Understandably, the main function of the second clamp 60 is to firmly fasten the upper end of the upper waterproof membrane sleeve 30 to the outer circumference of the steel pipe column 10. This prevents the upper waterproof membrane sleeve 30 from shifting or loosening during construction and use. Through the tightening action of the second clamp 60, the upper waterproof membrane sleeve 30 can fit tightly against the steel pipe column 10, ensuring its stability in the entire roof system, thus providing a reliable guarantee for the waterproof performance of the entire roof system. At the same time, the second clamp 60 not only plays a fixing role, but also forms a sealed connection between the upper waterproof membrane sleeve 30 and the steel pipe column 10. This sealed connection can effectively prevent rainwater from seeping into the roof interior through the gaps between the upper waterproof membrane sleeve 30 and the steel pipe column 10.

[0042] Reference Figure 1 According to the double-layer roof connection structure 1 provided by this utility model, it further includes a third clamp 70 and a fourth clamp 80. The third clamp 70 is used to clamp the upper end of the stainless steel plate sleeve 40 to the outer circumference of the steel pipe column 10. The fourth clamp 80 is sleeved on the middle and lower part of the stainless steel plate sleeve 40. The fourth clamp 80 is used to tighten the stainless steel plate sleeve 40, the upper waterproof membrane sleeve 30 and the lower waterproof membrane sleeve 20 together onto the steel pipe column 10.

[0043] Understandably, the stainless steel sleeve 40, as the outermost protective layer, needs to be securely installed on the steel pipe column 10 to prevent displacement or loosening during use. The third clamp 70 tightens the upper end of the stainless steel sleeve 40 onto the outer circumference of the steel pipe column 10. The clamping force ensures a tight fit between the sleeve and the column, guaranteeing the stable position of the stainless steel sleeve 40 on the column and providing a reliable outer protective foundation for the entire roof connection structure.

[0044] The third clamp 70 secures the upper end of the stainless steel sleeve 40, ensuring a tight seal between the stainless steel sleeve 40 and the steel pipe column 10. This effectively prevents rainwater from seeping into the roof through the gap between the stainless steel sleeve 40 and the steel pipe column 10.

[0045] The fourth clamp 80 is fitted over the lower middle part of the stainless steel plate sleeve 40, and together tightens the stainless steel plate sleeve 40, the upper waterproof membrane sleeve 30, and the lower waterproof membrane sleeve 20 onto the steel pipe column 10. This design creates a tight whole between the sleeves and between the sleeves and the steel pipe column 10, enhancing the connection strength between the layers, preventing relative displacement or loosening between the layers, and improving the overall integrity and stability of the entire double-layer roof connection structure 1.

[0046] Reference Figure 1 According to the present invention, a double-layer roof connection structure 1 is provided, wherein the lower end of the lower waterproof membrane sleeve 20 is welded to the roof waterproof membrane 2.

[0047] Understandably, by welding the lower end of the lower waterproof membrane sleeve 20 to the roof waterproof membrane 2, a continuous and seamless waterproof whole is formed between the two. This continuous waterproof layer can better prevent rainwater penetration, thereby significantly enhancing the waterproof performance of the entire roof system.

[0048] Reference Figure 1 According to the present invention, a double-layer roof connection structure 1 is provided, wherein the lower end of the upper waterproof membrane sleeve 30 is welded to the roof waterproof membrane 2.

[0049] Understandably, by welding the lower end of the upper waterproof membrane sleeve 30 to the roof waterproof membrane 2, the two are tightly bonded together to form a continuous, seamless waterproof whole. Simultaneously, welding creates a strong chemical bond between the upper waterproof membrane sleeve 30 and the roof waterproof membrane 2, enabling it to withstand greater external forces, such as wind, snow loads, and thermal expansion and contraction due to temperature changes, thus reducing the risk of structural damage caused by loosening or detachment.

[0050] In some embodiments, the lower end of the upper waterproof membrane sleeve 30 and the roof waterproof membrane 2, as well as the lower end of the lower waterproof membrane sleeve 20 and the roof waterproof membrane 2, can be welded using hot air welding, without any special limitation.

[0051] Furthermore, the weld 90 formed between the lower end of the lower waterproof membrane sleeve 20 and the roof waterproof membrane 2 is staggered from the weld 90 formed between the lower end of the upper waterproof membrane sleeve 30 and the roof waterproof membrane 2. This staggered welding provides multiple layers of waterproofing and improves the welding reliability at the joints.

[0052] Reference Figure 1 According to the double-layer roof connection structure 1 provided by this utility model, the openings at the upper and lower ends of the stainless steel plate sleeve 40 are respectively sealed and connected to the steel pipe column 10 and the roof waterproof membrane 2 layers by weather-resistant sealant 100.

[0053] Understandably, the openings at the top and bottom of the stainless steel sleeve 40 directly contact the steel pipe column 10 and the second layer of roof waterproofing membrane. These areas are critical points where rainwater may penetrate. By using weather-resistant sealant 100 to seal the connection, the tiny gaps at these openings can be effectively filled, preventing rainwater from seeping into the roof from these areas. Weather-resistant sealant 100 has excellent waterproof performance and can maintain its seal during long-term use, effectively preventing rainwater penetration even under complex climatic conditions (such as high temperature, low temperature, humidity, and ultraviolet radiation).

[0054] Reference Figure 1According to the present invention, a double-layer roof connection structure 1 is provided, wherein the upper end of the upper waterproof membrane sleeve 30 is sealed to the steel pipe column 10 by weather-resistant sealant 100.

[0055] Understandably, by using weather-resistant sealant 100 to seal the upper end of the upper waterproof membrane sleeve 30 to the steel pipe column 10, the tiny gaps between them can be effectively filled, preventing rainwater from seeping into the structure from these parts, and further improving the waterproof performance of the entire roof system.

[0056] Reference Figure 1 According to the present invention, a double-layer roof connection structure 1 is provided, wherein the upper end of the lower waterproof membrane sleeve 20 is sealed and connected to the steel pipe column 10 by weather-resistant sealant 100.

[0057] Understandably, the lower waterproof membrane sleeve 20 is sealed to the steel pipe column 10 via weather-resistant sealant 100, forming a multi-layered waterproof barrier together with the upper waterproof membrane sleeve 30. This multi-layered waterproof design significantly enhances the waterproof performance of the entire roof system, ensuring that rainwater cannot seep into the roof interior through any gaps.

[0058] Reference Figure 1 According to the double-layer roof connection structure 1 provided by this utility model, it further includes a butyl sealant layer 110, which is arranged in a ring between the outer wall surface of the steel pipe column 10 and the opening end of the roof waterproof membrane 2 corresponding to the steel pipe column 10.

[0059] Understandably, there are often tiny gaps at the connection between the roof waterproofing membrane 2 and the steel pipe column 10. These gaps can easily become channels for rainwater to seep in during rainfall, leading to roof leaks. The butyl sealant layer 110 has good flexibility and adhesion, and can tightly fill the gap between the outer wall of the steel pipe column 10 and the open end of the roof waterproofing membrane 2, forming a reliable waterproof barrier that effectively prevents rainwater intrusion and ensures the waterproofing effect of the roof.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
