Description

Technical Field

[0001] The present application relates to the field of roof technology, and in particular to a continuously welded color-coated stainless steel roof panel structure. Background Art

[0002] With the vigorous promotion of the continuous welded stainless steel roofing system in China, especially in coastal areas, it is widely used. The continuous welded stainless steel roofing system has the characteristics of high corrosion resistance, strong waterproof performance and high wind pressure resistance.

[0003] The continuous welded stainless steel roof system uses high-frequency resistance pressure welding, which generates instantaneous high temperature at the contact point of the two roof panels, and cooperates with a mechanical pressure roller to bond the molten parts of the two roof panels together. The welding surface is required to be smooth and uncoated, otherwise the roof panel will be directly perforated due to uneven conductivity. This strict requirement has led to the continuous welded stainless steel roof systems on the market being of a uniform stainless steel color, which is completely unable to meet the requirements of personnel for building colors.

[0004] Therefore, for color-coated stainless steel roof systems, most of them adopt the snap-on or hook-on connection methods. The snap-on method means that the small ribs of the roof panel are buckled on the plum blossom head of the support, and the large ribs of the adjacent roof panel are buckled on the small ribs, and locked by mechanical locking. The hook-on method means that the roof panel falls on the support with its shoulder folded, and the small ribs are embedded in the hooks of the support and locked, and the large ribs of the adjacent roof panel fall on the small ribs, and locked by mechanical locking.

[0005] Whether it is snap-on or hook-on, there is no seal between adjacent roof panels, and leakage is easy to occur between adjacent roof panels in rainy weather. In addition, under the action of strong wind loads, the bite of adjacent roof panels is easy to deform and disengage, causing the roof panels to fly away, creating secondary safety risks.

[0006] At present, extreme climates frequently occur around the world. There are media reports that when strong typhoons pass through, building roofs leak, indoor spaces become water curtain caves and waterfalls, and building roof panels are damaged or blown away. Therefore, strengthening the wind resistance and waterproofness of roof panels has become a top priority.

[0007] In view of the defects existing in the above-mentioned related technologies, the present application proposes a continuous welded color-coated stainless steel roof structure and process. Utility Model Content

[0008] In order to improve the problem of low stability and poor sealing when adjacent panels are connected together by mechanical locking, the present application provides a continuous welded color-coated stainless steel roof panel structure and process.

[0009] In the first aspect, the present application provides a continuously welded color-coated stainless steel roof panel structure adopts the following technical solution:

[0010] A continuously welded color-coated stainless steel roof panel structure comprises: panels which are successively arranged on the roof, the panels comprising a bottom plate and vertical plates arranged on both sides of the bottom plate, the bottom plate is used to abut against the roof, adjacent vertical plates are used to abut together, the bottom plate is provided with a coating, the vertical plates are not provided with a coating, and welds are provided between adjacent vertical plates.

[0011] By adopting the above technical solution, there is no coating on the vertical plate to meet the requirements of continuous welding. Adjacent panels are connected together by continuous welding, which is firmly fixed and has good sealing, thereby improving waterproofness and wind resistance.

Under the action of the restoring force of the spring plates, the two pressure plates abut against the side of the adjacent vertical plates that are far away from each other, and the buckle strips are fixed on the adjacent vertical plates. The operation is convenient and the construction efficiency is improved.

[0026] In a second aspect, the present application provides a continuous welding process for color-coated stainless steel roof panels, comprising the following steps:

[0027] Processing the panel into shape;

[0031] Temporarily positioning the bracket and the adjacent vertical plate together by spot welding;

[0032] Welding the bracket to the adjacent vertical plate by continuous welding;
