Description

Technical Field

[0001] The utility model relates to a connection structure of metal plates, in particular to a connection node for roof profiled metal plates. Background Art

[0002] With advances in architectural metal materials, processing, and coating technologies, metal roof panels, represented by color-coated steel plates, have become widely adopted in industrial buildings. Compared to conventional reinforced concrete roof panels, color-coated steel plates offer advantages such as light weight, high strength, aesthetics, durability, ease of construction, excellent thermal insulation, and waterproofing. Furthermore, due to their low deadweight, color-coated steel plate roofs reduce seismic effects, resulting in improved seismic performance.

[0003] The connection of metal roof panels is divided into lap profiled panels, bite profiled panels and snap-on profiled panels according to the connection method of the profiled panels:

[0004] ①Roof overlap profiled sheet: connected by self-tapping screws or bolts, such as W-600 roof panel, YX35-125-750 (V125) roof panel;

[0005] ② Roof bite-type corrugated sheets or snap-on corrugated sheets: including full bite connection, such as various types of vertical lock-seam single-wave sheets; full snap-on connection, such as wide concealed snap-on sheets, or a connection method with bite edges and middle snap-on at the board joints (i.e., snap-on + bite edge connection), such as YX114-300-600 / YX114-333-666 (Jiaochi III-A / B) roof panels.

[0006] Metallurgical industrial plants are usually tall, long, and have multiple spans. Figure 1 and 2 These are two common roof panel types used in metallurgical plants. The longest single-slope length can reach 100m. W-600 and Jiaochi III-A / B roof panels each have their own unique characteristics:

[0007] Figure 1 The following is a structural diagram of a roof panel type commonly used in metallurgical plants. The W-600 panel type features simple construction, good wind resistance, and easy maintenance and replacement. The roof panel and mounting brackets are connected using self-tapping screws or bolts. This connection method is susceptible to thermal expansion and contraction, and the resulting thermal stress can cause localized buckling, bulging, and wear of the roof panel. Therefore, it is not suitable for multi-span, single-slope roofs with excessive length. The maximum single-slope roof length is generally controlled at around 50 meters, which is extremely unsuitable for multi-span roofs.

[0008] Figure 2This is a structural diagram of another type of roof panel commonly used in metallurgical plants. ② The Jiaochi III-A / B type roof panel is connected to the fixed bracket by a bite + snap method, which is a fully concealed connection with good waterproof performance. However, for metallurgical plant projects that are being renovated and expanded, as well as for roof panels that are locally corroded, it is necessary to take measures to partially replace the roof panels. For the Jiaochi III-A / B type panels, the connection structure between the panels and the panels and the brackets adopts a bite connection method using an electric locking machine. Therefore, when replacing the roof panels, it is not possible to replace them by partially removing the roof panels. In current actual projects, it is often necessary to remove all roof panels within the entire slope length of the renovation area. This not only increases the workload, but also affects the normal operation of production due to the removal of the roof panels.

[0009] Therefore, in actual projects, for long single-slope roofs, the longitudinal overlap structure of the roof panels often adopts the method of raising the local roof height to form a high-low span roof form. Figure 3 This is a schematic diagram of a known method for partially raising the roof height to create a high-low span roof structure. The typical elevation is 2.0 to 2.5 meters. This solves the drainage problem of multi-span roofs and the overlap of extra-long roof panels. This structural design increases the number of structural components, exterior wall panels, roof gutters, and rainwater drainage pipes, increasing the project workload and construction cost.

[0010] Therefore, there is an urgent need to develop a reliable connection node for metal roof panels to effectively solve the longitudinal connection structure of ultra-long roof panels. Utility Model Content
