Description

Technical Field

[0001] This utility model relates to the field of building exterior decoration, and more specifically to a welded profiled stainless steel sheet and a connecting device. Background Technology

[0002] Metal roofing panels often use metal seam panels as a waterproofing layer and are widely used in the roofs of many public and industrial buildings. Currently, the connection between metal roofing panels and steel purlins is mostly a mechanical connection with fixed supports. While mechanical connections can ensure the waterproofing and load-bearing functions of most metal roofs, with the occurrence of extreme weather, strong winds and heavy rains can cause rainwater to overflow the seam of the metal seam panels and enter the interior through the cavities between the roof panels that are not completely sealed, posing a threat to the building's waterproofing. Furthermore, the metal seam panels rely on the seam force between the roof panels and supports to resist wind suction, which has limited resistance, and is particularly vulnerable to wind uplift in coastal areas with strong winds. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a welded profiled stainless steel sheet and connecting device, which has strong wind resistance and waterproof performance.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a welded profiled stainless steel plate and a connecting device, comprising a fixed base, a support plate connected to the fixed base, a C-shaped fastening piece on the upper part of the support plate, profiled stainless steel plates on both sides of the support plate, a left vertical edge and a right vertical edge adapted to the C-shaped fastening piece at both ends of the profiled stainless steel plate, interlocking parts at the ends of the left vertical edge and the right vertical edge, a first reinforcing structure between the left vertical edge and the right vertical edge, and a second reinforcing structure with several intervals between the left vertical edge, the right vertical edge and the C-shaped fastening piece.

[0005] Furthermore, both reinforcement structure one and reinforcement structure two are connected by welding. Reinforcement structure one is a continuous weld between adjacent profiled stainless steel plates, and reinforcement structure two is an intermittent weld between the left and right vertical sides and the C-shaped fastening piece.

[0006] Furthermore, the fixed base is Z-shaped and includes an upper plate and a lower plate. The upper plate is provided with an elongated hole for connecting with the support plate, and the lower plate is provided with several connecting holes for connecting with the structure. The lower plate is provided with several stamped protrusions to enhance the bending resistance of the lower plate.

[0007] Furthermore, the support piece includes a C-shaped fastening piece, a vertical support plate, and a bent plate formed sequentially, and is arranged in a zigzag shape. The bent plate is connected to the upper plate of the fixed base.

[0008] Furthermore, the C-shaped fastening piece has a rectangular open cross-section and includes an upper support plate, a lower support plate, and a vertical plate.

[0009] Furthermore, the profiled stainless steel sheet is U-shaped, and the interlocking parts of the profiled stainless steel sheet are pre-bent parts that bend inward by 90 degrees at both ends and a 7-shaped buckle plate. The horizontal length of the 7-shaped buckle plate is slightly longer than the length of the pre-bent parts, and the 7-shaped buckle plate can be fastened on the pre-bent parts during installation.

[0010] Furthermore, the profiled stainless steel sheet is composed of a left vertical side, a right vertical side, and a base plate, with a left transition connecting plate and a right transition connecting plate formed at a 135° angle to the base plate at the lower part of the left and right vertical sides, respectively.

[0011] Furthermore, the left and right vertical edges are nested on the outer and inner sides of the C-shaped fastening piece, respectively. The upper part of the left transition connecting plate / right transition connecting plate is bent to form a horizontal first bending platform. The first bending platform is bent upward at 90 degrees to form a first vertical edge. The first vertical edge is bent inward at 90 degrees to form a second bending platform. The second bending platform is bent upward at 90 degrees to form a second vertical edge. The second vertical edge is bent outward at 90 degrees to form a third bending platform. The third bending platform continues to bend upward at 90 degrees to form a third vertical edge. The third vertical edge is bent inward to form a pre-bent part / 7-shaped fastening plate.

[0012] Furthermore, the horizontal length of the third bending platform should ensure that the third vertical edge is perpendicularly aligned with the first vertical edge.

[0013] Furthermore, several continuous stiffening ribs are pressed into the middle of the base plate to improve its rigidity.

[0014] In summary, this utility model achieves waterproofing and wind resistance through two welding processes between adjacent profiled stainless steel sheets. The first weld uses a continuous welding process to connect the stainless steel sheets into a seamless whole, preventing rainwater from entering the room. The second weld uses an intermittent welding process to weld the stainless steel sheets to the connecting supports, which can resist strong wind suction. Furthermore, because the roof panel material is stainless steel, it has excellent weldability, and no rust will form at the weld, improving the durability of the roof panel. Specifically, it has the following beneficial effects:

[0015] 1. This utility model adopts continuous welding and 360° interlocking roof panels to form two waterproof barriers, effectively ensuring that the roof panels do not leak;

[0016] 2. This utility model uses a two-stage welding method to connect the profiled stainless steel plate and the fixing base, which greatly improves the wind resistance of the roof panel.

[0017] 3. The fixed base and support plate of this utility model can slide relative to each other, which can meet the expansion and contraction caused by the thermal expansion and contraction of the roof panel, avoid fatigue damage caused by long-term friction between the profiled stainless steel plate and the connecting and fixing device, and enhance the ability of the stainless steel roof panel to adapt to the environment.

[0018] 4. The fixing base, support plate and profiled stainless steel plate of this utility model are all made of stainless steel, which greatly improves the overall durability of the roof. Attached Figure Description

Detailed Implementation

[0027] Reference Figures 1 to 7 The specific implementation method of the welded profiled stainless steel plate and connecting device of this utility model will be further described.

[0028] A welded profiled stainless steel sheet and its connecting device include a fixed base 1, a support plate 2, and a profiled stainless steel sheet 3. The fixed base 1 is Z-shaped and includes an upper plate 11 and a lower plate 12.

[0029] The upper plate 11 is provided with an elongated hole 111, and the lower plate 12 is provided with a plurality of connecting holes 121 for connecting with the structure. The lower plate 12 is provided with a plurality of stamped protrusions 122, which can enhance the bending resistance of the lower plate 12.

[0030] The support piece 2 is made of stainless steel and is formed in sequence with a C-shaped fastening piece 21, a vertical support plate 22 and a bent plate 23, and is in the shape of a 90° zigzag line.

[0031] The C-shaped fastening piece 21 has a rectangular open section and includes an upper support plate 211, a lower support plate 212, and a vertical plate 213.

[0032] The bending plate 23 has a bolt hole 231 in the middle. The fixed base 1 and the support plate 2 are connected by bolts through the elongated hole 111 and the bolt hole 231. The support plate 2 can slide relative to the fixed base 1 to release the thermal expansion and contraction deformation of the roof panel.

[0033] The profiled stainless steel sheet 3 is U-shaped and consists of a left vertical side 31, a right vertical side 32, and a base plate 33.

[0034] The left vertical edge 31 and the right vertical edge 32 are formed by rolling stainless steel sheet through a forming equipment.

[0035] The lower part of the left vertical edge 31 forms a left transition connecting plate 310 at a 135° angle to the bottom plate 33.

[0036] The upper part of the left transition connecting plate 310 is bent to form a left first bending platform 311, and the left first bending platform 311 is horizontal.

[0037] The left first bending platform 311 is bent upward at 90° to form the left first vertical edge 312.

[0038] The left first vertical edge 312 is bent inward at 90° to form the left second bending platform 313.

[0039] The left second bending platform 313 is bent upward at 90° to form the left second vertical edge 314.

[0040] The second left vertical edge 314 is bent outward at a 90° angle to form the third left bending platform 315, and the third left bending platform 315 is further bent upward at a 90° angle to form the third left vertical edge 316. The horizontal length of the third left bending platform 315 should ensure that the third left vertical edge 316 is vertically aligned with the first left vertical edge 312.

[0041] The left third vertical edge 316 is bent inward at 90° to form a pre-bent part 317, which serves to strengthen the end.

[0042] The lower part of the right vertical edge 32 forms a right transition connecting plate 320 at a 135° angle to the bottom plate 33.

[0043] The upper part of the right transition connecting plate 320 is bent to form a right first bending platform 321, and the right first bending platform 321 is horizontal.

[0044] The right first bending platform 321 is bent upward at 90° to form the right first vertical edge 322.

[0045] The right first vertical edge 322 is bent inward at 90° to form the right second bending platform 323.

[0046] The right second bending platform 323 is bent upward at 90° to form the right second vertical edge 324.

[0047] The right second vertical edge 324 is bent outward at a 90° angle to form the right third bending platform 325, and the right third bending platform 325 is further bent upward at a 90° angle to form the right third vertical edge 326. The horizontal length of the left third bending platform 325 should ensure that the right third vertical edge 326 is vertically aligned with the right first vertical edge 322.

[0048] The top of the right vertical side 32 is a 7-shaped buckle plate 327. The horizontal section of the 7-shaped buckle plate 327 is slightly longer than the length of the pre-bent part 317, and the 7-shaped buckle plate 327 can be fastened on the pre-bent part 317 during installation.

[0049] The angle formed by the left first upright edge 312, the left second bending platform 313, the left second upright edge 314, and the left third bending platform 315 is nested outside the C-shaped fastening piece 21 and fits its shape. After the left upright edge 31 is installed on the support piece 2, the left third bending platform 315 can be supported on the upper support plate 211.

[0050] The angle formed by the right first upright edge 322, the right second bending platform 323, the right second upright edge 324, and the right third bending platform 325 is nested outside the C-shaped fastening piece 21 and fits its shape. After the right upright edge 32 is installed on the support piece 2, the right third bending platform 325 can be supported on the lower support plate 212.

[0051] The base plate 33 has several long stiffening ribs 331 pressed in the middle to improve its rigidity.

[0052] The fixed base 1 and the support plate 2 are assembled in the factory to form a whole. On site, they are first installed in place, and then the left vertical side 31 is installed so that it is supported on the upper support plate 211; then the adjacent stainless steel roof panel 3 is installed, so that the right second bending platform 323 of its right vertical side 32 is supported on the lower support plate 212, and at the same time, its 7-shaped buckle plate 327 is fastened on the pre-bent part 317.

[0053] After the adjacent profiled stainless steel sheet 3 is installed, the first step is to use a special metal roof panel automatic edge locking machine to lock the edges, so that the 7-shaped buckle 327 and the pre-bent part 317 interlock to form a 360° interlocking part 317 327, forming the first waterproof barrier of the roof panel.

[0054] The second step involves using an automatic welding machine to continuously weld the adjacent left third vertical edge 316 and right third vertical edge 326 of the adjacent profiled stainless steel sheet 3, forming a continuous weld seam 316326, which forms the second waterproof barrier of the roof panel.

[0055] The third step involves using an automatic welding machine to weld the adjacent left first vertical edge 312 and right first vertical edge 322 of the adjacent profiled stainless steel plates 3 to the vertical support plate 22 of the support piece 2, forming the first wind-resistant weld 312322. This weld is an intermittent weld according to the spacing of the support pieces 2.

[0056] The fourth step involves using an automatic welding machine to weld the adjacent left second vertical edge 314 and right second vertical edge 324 of the adjacent profiled stainless steel sheet 3 to the vertical plate 213 of the support piece 2, forming a second wind-resistant weld 314-324, thus creating an intermittent weld. This weld is intermittent based on the spacing of the support pieces 2. This further improves the wind uplift resistance of the entire roof panel.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
