Description

Technical Field

[0001] This utility model relates to the field of building construction, and specifically refers to a stainless steel roof panel installation structure. Background Technology

[0002] In existing standing seam metal roofing systems, metal roof panels are generally arranged longitudinally along their entire length. The standard length of a roof panel is typically 20 to 50 meters. However, the length of roof panels in many public buildings in China exceeds 50 meters, and even reaches 100 meters, which are unconventional ultra-long roof panels. Due to the large temperature difference in the environment where metal roofs are used, the roof panels need to maintain free expansion and contraction in the longitudinal direction under the effect of thermal expansion and contraction to ensure the release of temperature stress. The longer the roof panel, the greater the longitudinal expansion and contraction, and the greater the temperature stress. The roof panels are connected to the roof supports by welding, interlocking, or rolling seams. Therefore, the connection and expansion and contraction between the roof panels and the roof supports are key technologies and construction points for roof waterproofing and wind resistance.

[0003] Existing standing seam metal roofing systems use fixed supports to address the issue of roof panel expansion and contraction. The fixed supports rely on rigid frictional expansion and contraction between the upper end of the support and the locking joint of the roof panel to eliminate the temperature stress of the roof panel. However, long-term friction between the two can easily lead to loosening of the locking joint of the metal roof panel or wear and damage to the ribs, causing the roof's waterproofing and wind resistance functions to fail. Currently, there is a lack of effective technical solutions and construction and installation standards for ultra-long roof panel metal roofing systems. Utility Model Content

[0004] The purpose of this utility model is to overcome the defects of the prior art and provide a stainless steel roof panel installation structure to solve the problem that the existing technology of using fixed supports for roof panel installation is prone to damage after long-term use.

[0005] To achieve the above objectives, this utility model provides a stainless steel roof panel installation structure for installing stainless steel roof panels on roof purlins. The installation structure includes a fixed support and a sliding support.

[0006] The stainless steel roof panel located in the high slope area is fixedly connected to the roof purlin via the fixed support along its edge.

[0007] The stainless steel roof panel located in the low-slope area is slidably connected to the roof purlins at its bottom via the sliding support;

[0008] The sliding direction provided by the sliding support is the same as the tilt direction of the stainless steel roof panel.

[0009] By adopting this technical solution, fixed supports are set to fix the stainless steel roof panel to the roof purlins in the high slope area, while sliding supports are set to allow the stainless steel roof panel outside the high slope area to slide and connect to the roof purlins. The sliding of the stainless steel roof panel relative to the roof purlins adapts to the longitudinal expansion and contraction caused by the release of temperature stress, thereby avoiding wear on the stainless steel roof panel and increasing its service life.

[0010] Furthermore, the stainless steel roof panel is composed of several panel units connected in sequence, and the panel unit includes a base plate, a first rib, a second rib, and a U-shaped groove.

[0011] The first plate rib and the second plate rib are respectively formed by continuously bending the two sides of the substrate upwards;

[0012] The middle part of the first plate rib and the second plate rib is recessed towards the substrate to form a U-shaped groove;

[0013] Adjacent panel units are connected by overlapping and welding the tops of the first and second ribs.

[0014] By adopting this technical solution, the first and second plate ribs are combined to form a composite plate rib, which combines the stainless steel roof panels formed by connecting several panel units into a whole. The position of the composite plate rib is the main stress point, thereby transferring the force to the sliding support connected to that position. The sliding action of the sliding support adapts to the thermal expansion and contraction of the stainless steel roof panel. The U-shaped groove provides the prerequisite for the cooperation and connection with the sliding support.

[0015] Furthermore, the fixed support includes an L-shaped connector, a first base plate, and a first insulating pad;

[0016] The L-shaped connector is inverted, with its top transverse plate extending into the U-shaped groove on the first or second rib of the stainless steel roof panel. Its bottom is fixed to the first base plate, which presses the first insulating pad onto the roof purlin and fixes it to the roof purlin with screws.

[0017] By adopting this technical solution, after the L-shaped connector is connected to the first base plate, the whole assembly can be fixed to the roof purlin through the cooperation of the first base plate, the first insulating pad and screws. The top part of the L-shaped connector is exactly matched with the U-shaped groove on the first or second rib on the edge of the stainless steel roof panel edge panel unit. Then, the connection is completed by welding, thereby fixing the edge of the high slope area of ​​the stainless steel roof panel to the roof purlin.

[0018] Furthermore, the sliding support includes a second insulating pad, a second base plate, a sliding groove, a notch, a T-shaped sliding joint, and an elastic positioning block;

[0019] The second base plate presses the second insulating pad onto the roof purlin and is fixed to the roof purlin with screws;

[0020] The sliding groove runs horizontally through the second bottom plate and connects upward to the outside through the notch;

[0021] The bottom end of the T-shaped sliding member is inserted into the interior of the sliding groove through the notch;

[0022] The elastic positioning block is disposed between the side end face of the T-shaped sliding member and the inner end face of the sliding groove;

[0023] The top two ends of the T-shaped sliding member extend into the interior of the U-shaped grooves on the first and second plate ribs between adjacent panel units, respectively.

[0024] By adopting this technical solution, after the T-shaped sliding joint and the second base plate are connected to the stainless steel roof panel and the roof purlin respectively, the thermal expansion and contraction of the stainless steel roof panel will be transferred to the T-shaped sliding joint. When the T-shaped sliding joint is under force, its bottom will move along the sliding groove on the second base plate, thereby offsetting the interaction force between the stainless steel roof panel and the roof purlin, avoiding wear on the stainless steel roof panel, and playing a role in protecting the stainless steel roof panel. The second insulating pad can increase the stability of the connection between the second base plate and the roof purlin, and at the same time play a role in heat insulation, insulation and anti-electrochemical corrosion, ensuring the service life of the structure.

[0025] Furthermore, the sliding support also includes a slider and a fixing hole;

[0026] The slide bar is connected to the bottom end of the T-shaped sliding member and is slidably disposed inside the sliding groove;

[0027] The fixing holes are formed on the second insulating pad and the second base plate.

[0028] By adopting this technical solution, the bottom end of the T-shaped sliding joint is limited and slidably connected inside the sliding groove by means of a sliding strip; and the difficulty of fixing the second base plate and the second insulating pad to the roof purlin by using screws is reduced by setting a fixing block.

[0029] Furthermore, several sliding supports are evenly distributed between the connection points of adjacent panel units and the roof purlins.

[0030] By adopting this technical solution, the elasticity of the stainless steel roof panels is ensured, and the stability of their support is guaranteed.

[0031] Compared with the prior art, this utility model has the following advantages:

[0032] Fixed supports are installed to secure the stainless steel roof panel to the roof purlins in the high-slope areas, while sliding supports are installed to allow the stainless steel roof panel to slide and connect to the roof purlins outside the high-slope areas. By sliding the stainless steel roof panel relative to the roof purlins, it can accommodate the longitudinal expansion and contraction caused by the release of temperature stress, thereby avoiding wear on the stainless steel roof panel and increasing its service life.

By sliding the stainless steel roof panel 1 relative to the roof purlin 4, it adapts to the longitudinal expansion and contraction caused by the release of temperature stress, thereby avoiding wear on the stainless steel roof panel 1 and increasing its service life.

[0040] For further details, please refer to the appendix. Figure 1-2 The stainless steel roof panel 1 is composed of several panel units connected sequentially. Each panel unit includes a base plate 11, a first rib 12, a second rib 13, and a U-shaped groove 14. The first rib 12 and the second rib 13 are formed by continuously bending the two sides of the base plate 11 upwards. The middle of the first rib 12 and the second rib 13 are recessed towards the base plate 11 to form the U-shaped groove 14. Adjacent panel units are connected by overlapping and welding the tops of the first rib 12 and the second rib 13. The first rib 12 and the second rib 13 are combined to form a composite rib, which integrates the stainless steel roof panel 1 formed by connecting several panel units into a whole. The composite rib is the main stress point, thereby transferring the force to the sliding support 3 connected to that position. The sliding action of the sliding support 3 adapts to the thermal expansion and contraction of the stainless steel roof panel 1. The U-shaped groove 14 provides the preconditions for the cooperation and connection with the sliding support 3.

The bottom end of the T-shaped sliding member 35 is inserted into the sliding groove 33 through the notch 34. The elastic positioning block 36 is disposed between the side end face of the T-shaped sliding member 35 and the inner end face of the sliding groove 33. The top two ends of the T-shaped sliding member 35 extend to the first rib 12 and the second rib between adjacent panel units, respectively. Inside the U-shaped groove 14 on the 13; after the T-shaped sliding member 35 and the second base plate 32 are connected to the stainless steel roof panel 1 and the roof purlin 4 respectively, the thermal expansion and contraction of the stainless steel roof panel 1 will be transferred to the T-shaped sliding member 35. After the T-shaped sliding member 35 is subjected to force, its bottom will move along the sliding groove 33 on the second base plate 32, thereby offsetting the interaction force between the stainless steel roof panel 1 and the roof purlin 4, avoiding wear on the stainless steel roof panel 1, and playing a role in protecting the stainless steel roof panel 1; the second insulating pad 31 can increase the stability of the connection between the second base plate 32 and the roof purlin 4, and at the same time play a role in heat insulation, insulation and anti-electrochemical corrosion, ensuring the service life of the structure.

[0044] Furthermore, the sliding support 3 also includes a slide bar 37 and a fixing hole 38; the slide bar 37 is connected to the bottom end of the T-shaped sliding member 35 and is slidably disposed inside the sliding groove 33; the slide bar 37 enables the bottom end of the T-shaped sliding member 35 to be limited and slidably connected inside the sliding groove 33; the fixing hole 38 is opened on the second insulating pad 31 and the second base plate 32; by setting the fixing block 38, the difficulty of fixing the second base plate 32 and the second insulating pad 31 to the roof purlin 4 using screws is reduced.
