Description

Technical Field

[0001] The present utility model relates to the technical field of steel structure building roofing engineering, and more specifically, relates to a wind-resistant fixture matched with a snap-lock profiled plate and a roofing system having the same. Background Art

[0002] In steel structure buildings, metal profiled plates are widely used as roofing enclosure systems due to their advantages such as light weight, high strength, and convenient installation. The traditional connection method usually fixes the profiled plate to the underlying structure through independent metal supports, and then uses self-tapping screws or seaming equipment for fastening. However, this connection method has obvious limitations: the force points are concentrated, and the connection between the support and the plate surface mainly relies on the shear resistance of the fasteners, failing to fully utilize the structural strength of the profiled plate itself. Under the action of strong wind, especially wind suction, the roof panel is prone to upward deformation and vibration, leading to fatigue or brittle failure of the connection parts, and eventually causing local or even overall roof wind uplift. In addition, the exposed supports and fasteners also affect the integrity and aesthetics of the building appearance. Therefore, there is an urgent need in the art for a wind-resistant reinforced connection member that can work in coordination with the own structure of the profiled plate, has reasonable stress, is convenient to install, and has a simple and reliable appearance. Contents of the Utility Model

The fixture has a reasonable structural design and convenient installation, can closely fit with the specific contour of the snap-lock profiled plate and bear force in coordination, thereby greatly improving the overall wind uplift resistance of the roofing system, while maintaining the aesthetics of the building facade.

[0004] To achieve the above purpose, the present utility model adopts the following technical solution: a wind-resistant fixture matched with a snap-lock profiled plate, comprising an upper pressing cover, a left connecting base and a right connecting base, wherein the left connecting base and the right connecting base are symmetrically buckled on both sides of the standing seam of the metal profiled plate, and the upper pressing cover is arranged across the top of the standing seam and connected with the left connecting base and the right connecting base through fasteners.

[0005] Further, the upper pressing cover is arranged in a zigzag shape, comprising an inverted U-shaped vertical section and a pair of horizontal connecting sections extending horizontally outward from both sides of the vertical section.

[0006] Further, the bent portion of the inverted U-shaped vertical section is a rounded chamfer or a right-angle chamfer, and the width of the inverted U-shaped vertical section is adapted to the width of the standing seam.

[0007] Further, a plurality of upper connecting holes are formed in the horizontal connecting section of the upper pressing cover, for allowing fasteners to pass through to connect the left connecting base / the right connecting base.

[0008] Further, the left connecting base / right connecting base conforms to the shape of the vertical edge of the metal profiled plate, and comprises an upper connecting fastening section, a middle clamping section and a bottom supporting section which are sequentially arranged from top to bottom.

[0009] Further, the upper connecting fastening section is in a "┑" shape, and a plurality of lower connecting holes are formed in the middle part, for connecting with the upper pressing cover.

[0010] Further, the cross section of the middle clamping part is in a "匚" shape, and the shape of the opening side thereof matches the outline of the clamped part on the metal profiled plate.

[0011] Further, the bottom supporting section is in a "」" shape, and the lower horizontal end is supported on the metal profiled plate.

[0012] Further, the upper pressing cover, the left connecting base and the right connecting base are all made of metal plates by cold bending forming, and the material thereof is selected from one of stainless steel, galvanized carbon steel or aluminum alloy.

[0020] The following is in conjunction with the appendix Figures 1-7 The present invention provides a detailed description of the specific implementation of a wind-resistant clamp for a locking type profiled sheet and a roofing system thereof.

[0021] The present invention provides a wind-resistant clamp for locking type metal profiled sheets, which mainly consists of three core components: upper pressure cover 1, left connecting base 2 and right connecting base 3.

[0022] The upper pressing cover 1 is cold-bent from a metal plate into a "几" shape, and its core part consists of an inverted U-shaped vertical section 11 and a pair of horizontal connecting sections 12 formed by bending from both sides of the top of the vertical section 11. Circular upper connecting holes 13 are stamped on the horizontal connecting sections 12. The inner cavity width of the inverted U-shaped vertical section 11 is precisely designed to match the outer width of the standing seam lock 43 at the top of the target snap-lock metal profiled plate 4, so that the vertical section can be tightly fitted over the outside of the standing seam lock 43 during installation.

[0023] The left connecting base 2 and the right connecting base 3 are mirror-symmetric, which are integrally formed special-shaped metal parts with contours designed according to the shape of the standing edge of the profiled plate, and include three sections: the uppermost part is an upper connecting fastening section 23 in a "┑" shape, and the upper horizontal end 231 thereof is provided with a lower connecting hole 232, whose position corresponds to the upper connecting hole 13 of the horizontal connecting section 12 of the upper pressing cover 1; the middle part is a middle clamping portion 22 with a "匚"-shaped cross section, and the inner contour of this section is completely consistent with the outer contour of the full-length hollow groove 411 protruding on the standing edge of the profiled plate; the lowermost part is a bottom support section 21 in a "」" shape, and the lower horizontal end 211 thereof forms a flat support plane.

[0024] The applicable snap-lock metal profiled plate 4 has a characteristic structure at its standing edge portion: the top is a standing seam lock 43 for interlocking adjacent plates; a recessed full-length hollow groove 411 is arranged below the seam lock, and this groove forms a first step 41 which serves as a reinforcing structure for the plate rib; a horizontal second step 42 extends below the hollow groove to act as a bearing surface.

[0025] During installation, first align the left connecting base 2 and the right connecting base 3 with the standing edge of the metal profiled plate 4 from both sides. Make the middle clamping portions 22 of the left connecting base 2 and the right connecting base 3, that is, their "匚"-shaped parts, accurately snap into the full-length hollow groove 411 of the profiled plate, and at the same time ensure that the lower horizontal ends 211 of the bottom support sections 21 of the left connecting base 2 and the right connecting base 3 are stably seated on the second step 42 of the profiled plate. Subsequently, the inverted U-shaped vertical section 11 of the upper pressing cover 1 is inserted into the standing seam lock 43 of the metal profiled plate 4 from top to bottom. At this time, the horizontal connecting sections 12 on the left and right sides of the upper pressing cover 1 naturally rest on the upper horizontal ends 231 of the upper connecting fastening sections 23 of the left and right connecting bases, and the upper connecting holes 13 are aligned with the lower connecting holes 232. Finally, fasteners such as bolts or rivets are sequentially passed through the upper connecting holes 13 of the upper pressing cover 1 and the lower connecting holes 232 of the left connecting base / right connecting base, and tightened with nuts, thus completing the installation of a wind-resistant node.

[0026] In this way, the wind-resistant clamps and the profiled sheet form an organic whole. When the roof is subjected to wind suction, the force attempting to lift the profiled sheet is transmitted and decomposed: the upward force is transmitted to the left / right connecting base through the upper cover 1 and bolts; the left / right connecting base converts the force into a clamping force on the profiled sheet's continuous hollow groove 411 through its central clamping part 22, i.e., a horizontal constraint, and provides a reaction force through the support of the bottom support section 21 and the second step 42. This force transmission makes full use of the structural strength of the profiled sheet's own reinforcing ribs, i.e., the first step 41, avoiding stress concentration, thereby achieving excellent wind uplift resistance.

[0027] The components of this invention can be manufactured using materials with strong weather resistance, such as 304 or 316 stainless steel, hot-dip galvanized steel sheet, or 6063 aluminum alloy, to adapt to different environments and durability requirements. Their dimensions can be serialized according to different types of profiled sheets.

[0028] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. 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.
