Description

Technical Field

[0001] The utility model relates to the field of building exterior decoration, and more specifically to a support system for a buckle-lock type curled edge roof panel. Background Art

[0002] Metal lock edge plates are often used as waterproof layers for building metal roof panels, which are widely used in the roofs of many public buildings and industrial buildings. Currently, the connection methods between metal roof panels and supports usually include snap connection, lock seam connection, and curled edge connection, etc. In actual projects, due to the sensitivity of building roofs to external wind forces, in the vast majority of cases, the uplift force (wind suction force) is the main force. And these connection methods mainly rely on the friction force or biting force between the metal roof panel and the support to resist the external wind suction force. On the one hand, the friction coefficient between metals is small, and on the other hand, due to the small curled edge radius, the thickness of the support connection piece is limited, and neither can effectively improve the wind resistance bearing capacity of the roof panel. For areas with relatively large wind loads, especially the occurrence of extremely bad weather, these connection methods weaken the wind uplift resistance of the metal roof panel. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a support system for a buckle-lock type curled edge roof panel. The support system is connected to the metal roof panel by a two-way buckling method. The buckling force can provide a large tensile force, and at the same time, the buckling connection form is stable and will not cause the buckling force to decrease due to construction reasons, ensuring the reliable overall wind resistance performance of the metal roof.

[0004] To achieve the above object, the utility model provides the following technical solution: A support system for a buckle-lock type curled edge roof panel, including a fixed base, a tensile buckling plate, and metal roof panels on both sides. A mutually matching installation chute structure is provided between the upper part of the fixed base and the bottom of the tensile buckling plate. An arc-shaped panel buckling piece that cooperates with the metal roof panel is provided at the upper end of the tensile buckling plate, and panel support structures are also provided on both sides of the tensile buckling plate.

[0005] Further, the fixed base is L-shaped, including a horizontal section and a vertical section. The horizontal section is a fixed plane. The vertical section is sequentially bent 90° to form a first bending part and 180° to form a second bending part. An upper chute is formed between the first bending part and the second bending part. A lower chute adapted to the upper chute is provided at the lower part of the tensile buckling plate.

[0006] Furthermore, a sliding limit structure is provided between the tensile buckle pressing plate and the fixed base. The sliding limit structure includes sliding limit pieces arranged at both ends of the fixed base and limit openings arranged at both ends of the tensile buckle pressing plate. The sliding limit pieces are cut open at both ends of the second bending part, and the cut plates are bent outward by 90°.

[0007] Furthermore, the tensile buckle pressing plate is successively formed with an arc-shaped panel buckling piece, a vertical support plate, and a bending plate. The bending plate is bent 180° from the lower part of the vertical support plate, and a lower chute is formed between the bending plate and the vertical support plate.

[0008] Furthermore, the arc-shaped panel buckling piece is divided into left and right parts, which are bent in opposite directions with equal widths. Its radian matches the profile of the metal roof panel to ensure that it can reliably buckle the metal roof panel. The width of the arc-shaped panel buckling piece is equal to or greater than that of the vertical support plate.

[0009] Furthermore, the panel support structure includes a panel support plate. A long strip perforation for installing the panel support plate is provided in the middle of the vertical support plate. The vertical distance between the long strip perforation and the arc-shaped panel buckling piece is determined according to the profile of the metal roof panel. The panel support plate is bent from a metal flat plate and is divided into a left support plate and a right support plate.

[0010] Furthermore, the panel support plate is welded to the vertical support plate. The width of the left support plate is consistent with the length of the long strip perforation to ensure that the left support plate can just be inserted into it. The width of the right support plate is slightly larger than the length of the long strip perforation so that it can be clamped by the long strip perforation, and then a clamping weld is used to weld the left support plate to the vertical support plate.

[0011] Furthermore, the panel support plate is bent and clamped to the vertical support plate. At the junction of the left support plate and the right support plate, both ends are cut open to form bending cards. After the left support plate is inserted into the long strip perforation, the bending cards are bent downward by a certain angle, and the panel support plate is clamped at the long strip perforation.

[0012] Furthermore, the end part of the right support plate is locally bent downward in an arc to form a guiding plate piece to guide the installation of the metal roof panel in place.

[0013] Furthermore, the fixed base, the tensile buckle pressing piece, and the panel support structure are made of stainless steel or carbon steel. If they are all made of stainless steel with the metal roof panel, they are welded to the metal roof panel at the vertical support to form a support weld to improve the overall wind resistance performance of the metal roof panel.

[0014] In summary, the support system of the present utility model is connected to the metal roof panel by a two-way clamping method. The clamping force can provide a large tensile force, and at the same time, the clamping connection form is stable and the clamping force will not be reduced due to construction reasons, ensuring the reliable overall wind resistance performance of the metal roof. At the same time, if the material of the metal roof panel is stainless steel, the support system can correspondingly adopt stainless steel, and the connection form of welding the roof panel and the support can be realized, further improving the overall wind resistance performance of the metal roof. Compared with the prior art, the present utility model has the following beneficial effects:

[0015] The support system of the present utility model is connected to the metal roof panel by a clamping and additional welding method, improving the stability of the connection and enhancing the wind resistance performance of the roof panel;

[0016] The fixed base and the tensile clamping piece of the present utility model can produce relative sliding, which can meet the expansion and contraction amount generated by the thermal expansion and contraction of the roof panel, avoiding fatigue damage caused by long-term friction between the metal roof panel and the support system, and enhancing the ability of the metal roof panel to adapt to the environment;

[0017] The fixed base, the tensile clamping piece, the panel support plate and the metal roof panel of the present utility model can adopt stainless steel materials, greatly improving the overall durability of the roof. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Refer to Figures 1 to 12 The specific implementation mode of a support system for a cooperating buckle-type crimped roof panel of the utility model is further described.

[0032] A support system for a cooperating buckle-type crimped roof panel includes a fixed base 1, a tensile buckle pressing piece 2, and a panel support plate 3.

[0033] The fixed base 1 is L-shaped, the horizontal section is the fixed plane 11, and the vertical section is successively bent at 90° to form the first bending part 12 and bent at 180° to form the second bending part 13. An upper sliding groove 14 is formed between the first bending part 12 and the second bending part 13.

[0034] The fixed plane 11 is provided with a plurality of connection holes 15 connected to the structure.

[0035] An in-situ hole A16 is arranged in the middle of the first bending part 12.

[0036] The width of the fixed base 1 is greater than the width of the tensile buckle pressing piece 2, and its width is determined according to the thermal expansion and contraction amount of the metal roof panel.

[0037] A plurality of stamped ribs 17 are arranged on the fixed plane 11, which can enhance the bending resistance of the fixed plane 11.

[0038] Both ends of the second bending part 13 are cut open, and the cut-open plate is bent outward at 90° to form a sliding limit piece 18.

[0039] The tensile buckle pressing piece 2 is made of stainless steel or carbon steel, and is successively formed with an arc-shaped panel buckle piece 21, a vertical support plate 22 and a bent plate 23.

[0040] The arc-shaped panel buckle piece 21 is divided into left and right parts, which are bent in opposite directions, have equal widths, and the radian thereof conforms to the plate type of the metal roof panel 5, ensuring that it can reliably buckle the metal roof panel 5.

[0041] The width of the arc-shaped panel buckle piece 21 can be equal to that of the vertical support plate 22; to increase its tensile bearing capacity, the width of the arc-shaped panel buckle piece 21 can be widened to become the enhanced arc-shaped panel buckle piece 21b.

[0042] The lower part of the tensile buckle pressing piece 2 is bent 180° to form a bent plate 23, and a sliding groove 24 is formed between the bent plate 23 and the vertical support plate 22.

[0043] The fixed base 1 and the tensile buckle pressing piece 2 are combined and hooked through the upper sliding groove 14 and the lower sliding groove 24, and the tensile buckle pressing piece 2 can slide relative to the fixed base 1 to release the thermal expansion and contraction deformation of the roof panel.

[0044] Rectangular limiting openings 25 are punched at both ends of the lower part of the vertical support plate 22, and the width of the notch is slightly larger than the plate thickness of the fixed base 1, ensuring that when the tensile buckle pressing piece 2 slides to the end of the fixed base 1, the sliding limiting piece 18 is clamped into the rectangular limiting opening 25 to limit the tensile buckle pressing piece 2 from sliding out of the fixed base 1.

[0045] An in-situ hole B26 is arranged in the middle of the bent plate 23, and its size is the same as that of the in-situ hole A16. After the tensile buckle pressing piece 2 and the fixed base 1 are combined, its position is in the middle of the fixed base 1, and the in-situ hole B26 and the in-situ hole A16 are mutually penetrated, and an in-situ stud 4 is arranged at the penetrated place, which is made of an organic polymer material, ensuring that the original position of the tensile buckle pressing piece 2 is in the middle position of the fixed base 1. After the metal roof panel 5 is installed, the metal roof panel 5 drives the tensile buckle pressing piece 2 to slide due to thermal expansion and contraction, and cuts off the in-situ stud 4 to slide relative to the fixed base 1.

[0046] The middle part of the tensile buckle pressing piece 2 is the vertical support plate 22, and a long strip perforation 27 is punched and formed in the middle thereof, and the height of the long strip perforation 27 is consistent with the thickness of the panel support plate 3.

[0047] The vertical distance L between the long strip perforation 27 and the arc-shaped panel buckle piece 21 is determined according to the plate type of the metal roof panel 5.

[0048] The panel support plate 3 is bent from a metal flat plate and is divided into a left support plate 31 and a right support plate 32.

[0049] The width of the left support plate 31 is the same as the length of the long strip perforation 27, ensuring that the left support plate 31 can be just inserted therein. The width of the right support plate 32 is slightly larger than the length of the long strip perforation 27, so that it can be clamped by the long strip perforation 27, and then a clamping weld 33 is used to weld the left support plate 31 and the vertical support plate 22, completing the connection between the panel support plate 3 and the tensile buckle pressing piece 2.

[0050] The left support plate 31 can also be connected to the vertical support plate 22 by bending. That is, at the junction of the left support plate 31 and the right support plate 32, at a distance equal to the thickness of the tensile buckle pressing piece 2, about 5 mm in length is cut at both ends to form the bending card 311. After the left support plate 31 is inserted into the long strip perforation 27, the bending card 311 is bent downward by a certain angle, so that the panel support plate 3 is clamped at the long strip perforation 27.

[0051] The end of the right support plate 32 is locally bent into an arc downward to form a guiding plate piece 321, which can guide the installation of the metal roof panel 5 in place.

[0052] The fixed base 1, the tensile buckle pressing piece 2 and the panel support plate 3 can be made of stainless steel or carbon steel. When made of stainless steel, if the metal roof panel 5 is also made of stainless steel, a welding method can be further adopted at the vertical support plate 22 to weld it to the metal roof panel 5 to form a support weld 244, so as to improve the overall wind resistance performance of the metal roof panel 5.

[0053] The metal roof panel 5 described in the present utility model is a snap-lock type 360° crimped weldable metal roof panel, which is used in cooperation with the support system of the present utility model.

[0054] The above are only the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the idea of the present utility model belong to the protection scope of the present utility model. It should be pointed out that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as the protection scope of the present utility model.
