Description

Technical Field

[0001] This invention relates to the field of building engineering technology, and in particular to a wind-resistant reinforcement structure for metal roofs. Background Technology

[0002] In coastal areas, typhoons frequently cause damage to building structures. For most steel-framed buildings, wind damage primarily involves the collapse of the building envelope, particularly the uplift of metal roof panels, resulting in significant economic losses. Conventional measures to strengthen the wind resistance of metal roof panels include adding wind-resistant clips and wind-resistant strips.

[0003] See Figure 1 , Figure 1 The diagram illustrates the application of a prior art wind-resistant clamp to a metal roof panel. The wind-resistant clamp 102 consists of two independent clamping plates connected by bolts. A fastening bolt assembly is connected to the upper part of the clamping plates. The wind-resistant clamp clamps the rolled edge portion 101a of the two metal roof panels 101 to lock the edge. However, when the metal roof panel is deformed by wind, the metal roof panels on both sides of the wind-resistant clamp bulge upwards, causing the bottom of the wind-resistant clamp to tend to open outwards, thus losing the effect of restraining the rolled edge.

[0004] See Figure 2 , Figure 2 The illustration shows the application of existing wind-resistant strips to a metal roof panel. The wind-resistant strips are applied to the middle of the metal roof panel. Although the wind-resistant strips have a good effect on improving the wind resistance of the metal roof panel, it is necessary to drive screws into the metal roof panel 101 to fix the wind-resistant strip 103. Drilling holes in the metal roof panel 101 can easily lead to the risk of roof leakage.

[0005] As mentioned above, existing wind-resistant clamps and wind-resistant strips are not very reliable and pose a risk of leakage. Therefore, a reliable and quick-to-implement method is needed to effectively improve the wind resistance of metal roofs. Summary of the Invention

[0006] In order to solve the above problems, the present invention provides a wind-resistant reinforced structure for metal roofs.

[0007] The technical problem to be solved by the present invention is achieved through the following technical solution:

[0008] This invention provides a wind-resistant reinforcement structure for metal roofs, characterized in that it includes horizontal braces and supports. The supports are disposed at the connection of two overlapping metal roof panels. The upper end of the support metal plate is sandwiched between the two overlapping metal roof panels and together with the two metal roof panels forms a rolled edge structure. The rolled edge structure is sandwiched between the lower ends of a first clip and a second clip. There are two horizontal braces, which are respectively fixed to the outer side of the lower end of the first clip and the outer side of the lower end of the second clip. The two horizontal braces are symmetrically arranged, and the height of the horizontal braces is greater than the height of the rolled edge structure.

[0009] As a preferred embodiment, the wind-resistant reinforcement structure for metal roofs provided by the present invention also has the following feature: the cross braces are angle steel.

[0010] As a preferred embodiment, the wind-resistant reinforcement structure for metal roofs provided by the present invention also has the following feature: the cross bracing is a T-shaped steel.

[0011] As a preferred embodiment, the wind-resistant reinforcement structure for metal roofs provided by the present invention also has the following feature: the cross brace is welded to the first clip and the second clip.

[0012] As a preferred embodiment, the wind-resistant reinforcement structure for metal roofs provided by the present invention also has the following feature: in the axial direction of the cross brace, when there are multiple wind-resistant clamps, the two ends of the cross brace located between two wind-resistant clamps are respectively fixed to the wind-resistant clamps on both sides.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In the wind-resistant reinforcement structure for metal roofs of this invention, the horizontal bracing rods symmetrically arranged on the outside of the wind-resistant clamps can counteract the outward tension generated at the lower end of the clamps by their own axial bearing capacity, thereby minimizing the loosening and deformation of the rolled edges and improving the wind resistance of the metal roof. Furthermore, the presence of the horizontal bracing rods prevents the metal roof panels from being easily blown over by the wind. Simultaneously, the wind-resistant reinforcement structure of this invention eliminates the need for nailing the metal roof panels, avoiding the risk of drilling and leakage, making installation convenient and suitable for rapid reinforcement of metal roofs during typhoons. Secondly, the supports and the edges of the metal roof panels together form a rolled edge structure, with the supports providing support and improving overall stability. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the following embodiments, in conjunction with the accompanying drawings, will specifically illustrate the technical solution of this invention.

[0022] See Figure 3 This embodiment provides a wind-resistant reinforcement structure for a metal roof, including a wind-resistant clamp 1, a cross brace 2, and a support 3.

[0023] See Figure 3 and Figure 4 In this embodiment, the wind-resistant clamp 1 adopts the existing wind-resistant clamp 1, which is composed of a first clamping piece 1a, a second clamping piece 1b and a fastening bolt assembly.

[0024] Support 3 is a commercially available product; see [link / reference]. Figure 6 The support 3 consists of a metal support body 31 and a metal sheet 32. The metal support body 31 is provided with a slot hole 31a. The lower end of the metal sheet 32 ​​is installed in the slot hole 31a. As a commercially available product, the support body 31 and the metal sheet 32 ​​are installed as one unit before leaving the factory. The metal sheet 32 ​​can be bent and rolled by the user.

[0025] See Figure 3 Support 3 is installed at the connection point of two overlapping metal roof panels 4. The bottom of support 3 is fixed to the roof structure, which refers to the concrete roof of the building itself or the roof structure (such as a steel frame). In practice, conventional methods such as casting, welding, and bolting can be used to fix support 3 to the roof structure to improve stability.

[0026] See Figure 3 and Figure 4 The upper end of the support 3 (i.e., the upper end of the metal sheet 32) is sandwiched between two overlapping metal roof panels, and the user manually bends the upper end of the metal sheet 32 ​​together with the two metal roof panels to form a rolled edge structure (e.g., Figure 4 (As shown in B).

[0027] See Figure 3 and Figure 4 There are two horizontal support rods 2, which are fixed to the outer side of the lower end of the first clamping piece 1a and the outer side of the lower end of the second clamping piece 1b of the wind-resistant clamp 1, respectively, and the two horizontal support rods 2 are symmetrically arranged. The height of the horizontal support rods 2 is greater than the height of the rolled edge structure, thus ensuring that the rolled edge structure is located between the two horizontal support rods, and the effective range of the horizontal support rods covers the rolled edge structure.

[0028] The cross brace 2 is made of angle steel or T-shaped steel, and the cross brace is fixed to the first clamp and the second clamp by spot welding.

[0029] In some embodiments, multiple wind-resistant clamps 1 may be installed on a metal roof. For example... Figure 5 As shown, in the axial direction of the cross brace 2, when there are multiple wind-resistant clamps 1, the two ends of the cross brace 2 located between two wind-resistant clamps are fixed to the wind-resistant clamps 2 on both sides respectively.

[0030] The working principle of the wind-resistant reinforcement structure for the metal roof in this embodiment is as follows: Under the action of wind suction, the metal roof panels on both sides of the crest undergo upward bending deformation, generating outward tension at the lower opening of the wind-resistant clamp 1. Due to the presence of symmetrically arranged horizontal braces 2, the horizontal braces 2 offset this outward tension with their own axial bearing capacity, thereby ensuring that the lower opening of the wind-resistant clamp 1 always tightly clamps the rolled edge of the metal roof panel, preventing the rolled edge from loosening and deforming prematurely, thus improving the wind resistance of the metal roof. Secondly, the supports play a supporting role, and the supports together with the edge of the metal roof panel form a rolled edge structure, improving the overall stability.

[0031] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention are included within the scope of protection of the present invention.
