Abstract
Description
Technical Field
[0001] This utility model relates to the field of building roofing technology, specifically to an energy-dissipating support structure for a metal roofing system. Background Technology
[0002] With the continuous development of science and technology, the application of profiled metal roofing panels in building envelopes has brought tremendous development opportunities. Metal roofing boasts advantages such as easy processing and forming, lightweight yet high strength, and aesthetic appeal, and has been widely used in various landmark structures in my country, such as airports, stadiums, and grand theaters—large-span structures. However, as a lightweight building envelope system, metal roofing is susceptible to failure in the connections between components under strong winds and significant temperature differences, leading to the roof being lifted and blown off by strong winds, posing significant safety hazards and property losses to the public. Investigations and analyses of damaged roofing systems reveal that the main points of failure occur at the supports. Screw pull-out and breakage frequently occur at the connection nodes between supports and purlins, resulting in localized failure of the roofing system's wind uplift resistance and affecting its normal use. Therefore, the support connection is a weak point in the metal roofing system, and a novel support structure requires further research.
[0003] In related technologies, the reinforcement of supports is often used to improve the wind uplift resistance of roof systems. However, these reinforcement methods are relatively complex in structure, costly, and difficult to implement. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide an energy-dissipating support structure for a metal roofing system.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0006] An energy-dissipating support structure for a metal roofing system includes multiple roof panels and supports for supporting the roof panels;
[0007] Its features are:
[0008] The support is an L-shaped component consisting of a support part and a base part, and the support part is provided with a spring structure whose extension direction is perpendicular to the base part.
[0009] The joints between the roof panels are welded to the top of the support, preferably by an electric welding machine.
[0010] Therefore, when the metal roofing system is subjected to external wind loads, the roof panels generate significant internal forces and deformations due to the pressure difference between the top and bottom of the roof panels. The support parts of the supports are subjected to extremely strong vertical stress perpendicular to the base. Since the support parts and the base are connected in an L-shape, they are easily damaged under the action of vertical stress. However, the support parts with spring structures have elastic contraction characteristics, which reduces the vertical stress and deformation, reduces the load transmitted to the base and self-tapping screws, and protects the supports. This enhances the wind resistance of the roofing system and reduces the damage caused by strong winds to the entire structure.
[0011] The term "load" should be interpreted broadly, for example, it can refer to pressure, tension, or other vertical forces.
[0012] Therefore, this utility model uses an L-shaped component consisting of a support part and a base part as a support, which can more stably support the entire metal roofing system. Furthermore, by setting a spring structure in the support part with the extension direction perpendicular to the base part, the damage of external loads to the support and the fasteners between the support and the purlin can be reduced, thereby improving the wind uplift resistance of the support structure and reducing the damage caused by strong winds to the entire structure.
[0013] Preferred: See Figure 1 and Figure 2 The spring structure is a folded spring structure extending in the vertical direction. This spring structure can be set at any position of the support to play an elastic contraction role to consume external wind load.
[0014] Preferably, the spring structure is located at the connection between the support and the base.
[0015] Preferred: See Figure 3 The support portion includes an upper support portion and a lower support portion that are staggered in the horizontal direction. The spring structure is connected between the lower end of the upper support portion and the upper end of the lower support portion, and the spring structure is a folded spring structure that extends in the horizontal direction.
[0016] Preferred: See Figure 4 The support portion includes an upper support portion and a lower support portion that are staggered in the horizontal direction. The spring structure is connected between the lower end of the upper support portion and the upper end of the lower support portion, and the spring structure is a wave-shaped structure extending in the horizontal direction.
[0017] Preferably, the support portion and the base portion are perpendicular to each other.
[0018] Preferably, the roof panels consist of two pieces, with the top of the support sandwiched between the edges of the two roof panels and welded together to form a straight weld. Preferably, the straight weld is made of a waterproof material with the same strength as the roof panels.
[0019] Preferably, the energy-dissipating support structure of the metal roofing system further includes a purlin, the base of which is tightly attached to the top surface of the purlin, and the base is connected to the purlin by at least one self-tapping screw. The self-tapping screw preferably has a drill tip, but it can also be replaced with other screws or nails.
[0020] Preferably, the purlins are arranged horizontally.
[0021] Preferably, the purlin is a square steel pipe.
[0022] Preferably, the roof panels, supports, and purlins are made of stainless steel, carbon steel, or aluminum alloy, and the self-tapping screws are made of stainless steel or carbon steel.
[0023] Compared with the prior art, the present invention has the following beneficial effects:
[0024] First, this utility model uses an L-shaped component consisting of a support part 2-1 and a base part 2-2 as a support 2, which can more stably support the entire metal roofing system. Furthermore, by setting a spring structure 2-1-1 with an extension direction perpendicular to the base part 2-2 in the support part 2-1, the damage of external loads to the support 2 and the fasteners between the support 2 and the purlin 4 can be reduced, thereby improving the wind uplift resistance of the support structure and reducing the damage caused by strong winds to the entire structure.
[0025] Secondly, by adopting a folded spring structure extending in the horizontal direction, or a folded spring structure extending in the horizontal direction, or a wave-shaped structure extending in the horizontal direction as the spring structure 2-1-1, this utility model can improve the buffer energy dissipation capacity of the support 2, thereby further improving the wind uplift resistance of the support structure.

[0030] Figure 4 This is a structural schematic diagram of Embodiment 4 of the present utility model. Detailed Implementation
[0031] The present invention will now be described in detail with reference to the embodiments and accompanying drawings to help those skilled in the art better understand the inventive concept of the present invention. However, the scope of protection of the claims of the present invention is not limited to the following embodiments. For those skilled in the art, all other embodiments obtained without creative effort without departing from the inventive concept of the present invention are within the scope of protection of the present invention.
[0032] Example 1
[0033] like Figures 1 to 4 As shown, the present invention discloses an energy-dissipating support structure for a metal roofing system, including multiple roof panels 1 and supports 2 for supporting the roof panels 1.
[0034] The support 2 is an L-shaped component consisting of a support part 2-1 and a base part 2-2, and the support part 2-1 is provided with a spring structure 2-1-1 whose extension direction is perpendicular to the base part 2-2;
[0035] The joints between each roof panel 1 are welded to the top of the support 2-1, preferably by means of an electric welding machine.
[0036] Therefore, when the metal roofing system is subjected to external wind loads, due to the pressure difference between the top and bottom of the roof panel 1, the roof panel 1 generates significant internal forces and deformations. The support part 2-1 of the support 2 is subjected to extremely strong vertical stress perpendicular to the base part 2-2. Since the support part 2-1 and the base part 2-2 are connected in an L-shape, the support part 2-1 and the base part 2-2 are easily damaged under the action of vertical stress. However, the support part 2-1 with the spring structure 2-1-1 has its own elastic contraction characteristics, which reduces the vertical stress and deformation, reduces the load transmitted to the base part 2-2 and the self-tapping screws, and plays a role in protecting the support 2, thereby enhancing the wind resistance of the roofing system and reducing the damage caused by strong winds to the entire structure.
[0037] The term "load" should be interpreted broadly, for example, it can refer to pressure, tension, or other vertical forces.
[0038] Therefore, this utility model uses an L-shaped component consisting of a support part 2-1 and a base part 2-2 as the support 2, which can more stably support the entire metal roofing system. Furthermore, by setting a spring structure 2-1-1 with an extension direction perpendicular to the base part 2-2 in the support part 2-1, the damage of external loads to the support 2 and the fasteners between the support 2 and the purlin 4 can be reduced, thereby improving the wind uplift resistance of the support structure and reducing the damage caused by strong winds to the entire structure.
[0039] The above is the basic implementation method of this embodiment one, and further optimizations, improvements and limitations can be made based on this basic implementation method:
[0040] Preferably, the support portion 2-1 and the base portion 2-2 are perpendicular to each other.

[0042] Preferably, the energy-dissipating support structure of the metal roofing system further includes a purlin 4, and the base portion 2-2 of the support 2 is tightly attached to the top surface of the purlin 4, and the base portion 2-2 is connected to the purlin 4 by at least one self-tapping screw 5. Preferably, the self-tapping screw 5 has a drill tip, but it can also be replaced with other screws or nails.
[0043] Preferably, the purlins 4 are arranged horizontally.
[0044] Preferably, the purlin 4 is a square steel pipe.
[0045] Preferably, the roof panel 1, support 2 and purlin 4 are made of stainless steel, carbon steel or aluminum alloy, and the self-tapping screw 5 is made of stainless steel or carbon steel.

[0049] The above is the basic implementation method of this embodiment two, and further optimizations, improvements and limitations can be made based on this basic implementation method:
[0050] Preferably, the spring structure 2-1-1 is located at the connection between the support part 2-1 and the base part 2-2.
[0051] Example 3
[0052] Based on the above embodiment one, this embodiment three also adopts the following preferred implementation method:
[0053] See Figure 3The support portion 2-1 includes an upper support portion 2-1A and a lower support portion 2-1B that are staggered in the horizontal direction. The spring structure 2-1-1 is connected between the lower end of the upper support portion 2-1A and the upper end of the lower support portion 2-1B, and the spring structure 2-1-1 is a folded spring structure that extends in the horizontal direction.
