Description

Technical Field

[0001] This application relates to the technical field of building engineering, and in particular to a novel metal roof expansion joint structure device. Background Technology

[0002] In the construction industry, metal roofing is widely used in various industrial and civil buildings due to its advantages such as high strength, light weight, and convenient construction. With the continuous development of the construction industry, the performance requirements for metal roofing are becoming increasingly stringent, especially in terms of coping with different environmental conditions and changes in building structure.

[0003] In the treatment of metal roof expansion joints in related technologies, some methods involve using an overlapping method at the expansion joint, where adjacent roof panels overlap by a certain length. The expansion pressure is relieved by the relative movement of the overlapping parts. This is achieved by setting support columns and cover plates on the roof. The cover plates have grooves that are set along the width of the expansion joint, and the support columns slide in the grooves.

[0004] Although the sliding cover structure has the ability to adapt to expansion and contraction, dust and debris tend to accumulate in the sliding parts during long-term operation, which seriously affects its sliding performance and reduces the expansion and contraction adjustment ability of the expansion joint.

Other embodiments obtained by those skilled in the art in conjunction with the embodiments of this utility model without creative effort are also within the protection scope of this utility model.

[0030] Roofs are generally composed of a single unit. To mitigate stress changes caused by thermal expansion and contraction or earthquakes, roof expansion joints are installed to ensure the stability and safety of the building. The installation of expansion joints must pay attention to sealing and waterproofing. The roof expansion joint construction device of this application is particularly suitable for metal roofs, with good waterproofing and sealing effects, as well as certain thermal insulation and sound insulation effects.

[0031] refer to Figure 1 This application provides a novel metal roof expansion joint construction device, including a roof 1, a support structure 2, and a waterproof panel 3. The support structure 2 is fixed on the roof 1, and the waterproof panel 3 is laid on the support structure 2.

[0032] refer to Figure 1 and Figure 2 Specifically, roof 1 includes a first roof panel 100 and a second roof panel 101, with a roof gap 102 formed between them. The first roof panel 100 and the second roof panel 101 are typically made of metal, such as aluminum alloy or stainless steel. These metals have good strength and corrosion resistance, and can withstand certain external forces and environmental erosion. Of course, other metal materials with similar properties can also be used depending on actual needs. During installation, the first roof panel 100 and the second roof panel 101 need to ensure a certain degree of flatness and spacing to form a suitable roof gap 102.

[0033] refer to Figures 1-3The supporting structure 2 includes supporting columns 21 fixedly connected to the first roof panel 100, supporting beams 22 fixedly connected to the supporting columns 21, and roof support assembly 23. Specifically, multiple supporting columns 21 are arranged perpendicularly to the first roof panel 100 and spaced parallel to each other.

Cold-formed galvanized purlins 51 can be used. The purlins 52 are fixed to the purlins 51 in the same way. Cold-formed galvanized Z-shaped purlins 52 can be used. The supports 231 are fixedly installed on the purlins 52, and bolting can be used for easy installation and disassembly.

[0038] refer to Figure 2 and Figure 3A sealing layer 6 is laid between the roof support assembly 23 and the purlin 52, forming an insulation layer 7 between the sealing layer 6 and the roof 1. The sealing layer 6 is wavy at the location of the roof gap 102, allowing for expansion and contraction. The sealing layer 6 can expand or compress with changes in the roof gap 102. The sealing layer 6 can be made of high-polymer waterproof membrane, preferably TPO waterproof membrane (thermoplastic polyolefin). These sealing layers 6 have good sealing performance and can prevent the penetration of air and moisture. The insulation layer 7 can be filled with insulation materials such as glass wool and rock wool. These materials have good insulation performance, reducing heat transfer and improving the roof's insulation effect. In other embodiments, sound insulation materials such as sound insulation cotton can also be filled to provide sound insulation. The end face of the sealing layer 6 near the roof gap 102 is fixed to the support column 21 by a clamp 8. The clamp 8 is generally made of metal, and the sealing layer 6 is fixed to the support column 21 by tightening bolts, ensuring the stability and sealing performance of the sealing layer 6.
