Description

Technical Field

[0001] This utility model relates to the field of building metal roofing technology, and in particular to a metal roofing conversion connection clamp. Background Technology

[0002] In metal roofing systems, to meet diverse functional requirements, various additional facilities or devices often need to be installed on the existing roof. This typically requires a reliable intermediate connector—a conversion coupling—to securely and firmly fix these facilities to specific roof structures (such as standing seams, purlins, etc.). Traditionally, such couplings mostly adopt a basic form consisting of two main pieces combined on the left and right sides.

[0003] However, traditional designs often have some inherent flaws. For example, to accommodate installation or locking requirements, the cross-sectional shapes of the left and right pieces are often designed to be different. This asymmetrical design brings many inconveniences to actual production, inventory management, and on-site installation: two different parts need to be manufactured separately during production, increasing mold costs and process complexity; inventory management requires distinguishing between left and right parts, which is prone to errors; during on-site installation, construction personnel must identify the left and right pieces in advance and match them correctly. In complex working conditions such as poor lighting or working at heights, misinstallation is very likely to occur, leading to reduced installation efficiency and even potential structural safety hazards due to incorrect installation.

[0004] Furthermore, the connection points between traditional clamps and the superstructure (such as keel supports) are usually fixed or have a very limited adjustment range. This makes the positioning accuracy requirements for the superstructure extremely high during installation, lacking the necessary on-site adjustment tolerance. When it is necessary to adapt to additional facilities of different specifications or to make fine-tuning of the position, traditional clamps often prove inadequate and lack flexibility, sometimes even requiring the customization of different models, increasing costs and management difficulties. Clearly, existing technology still needs improvement and enhancement. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a metal roof conversion connection clamp to solve one or more problems existing in the prior art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a metal roof conversion connection clamp, comprising a pair of symmetrically arranged clamping bodies, each clamping body comprising a clamping part, a clamping part, a connecting arm, and a fixing plate; the clamping part is connected to the bottom end of the clamping part for clamping and fixing the roof structure; the connecting arm is L-shaped, with one end connected to the top end of the clamping part and the other end connected to the fixing plate; the connecting arm and the fixing plate form an installation notch, and the installation notches of the two clamping bodies are joined together to form a T-shaped groove; the T-shaped groove is used to accommodate the head of the bolt connecting the two clamping bodies, allowing the bolt to slide and adjust its position within the groove.

[0007] In one embodiment of the present invention, the inner wall of the clamping part is provided with anti-slip teeth, which extend along the clamping direction.

[0008] In one embodiment of this utility model, the thickness of the clamping part gradually decreases from the connecting end connected to the clamping part toward the free end, forming a wedge-shaped structure.

[0009] In one embodiment of the present invention, the clamping part is provided with at least one fastening screw hole.

[0010] In one embodiment of the present invention, an anti-detachment block is also included. The anti-detachment block is integrally formed at the bottom edge of the fixing plate. The anti-detachment block is set perpendicular to the fixing plate, and the anti-detachment blocks of the two clamping bodies are arranged opposite to each other and located at the two sides of the T-slot, forming a limiting structure for the bolt head.

[0011] In one embodiment of the present invention, the top surface of the fixing plate is provided with serrated anti-slip texture, which extends along the length direction of the fixing plate.

[0012] As described above, the metal roof conversion connection clamp of this utility model has the following beneficial effects: By adopting a pair of symmetrically arranged clamping bodies, structural balance and stability are achieved, effectively improving the uniformity of force distribution during installation. Each clamping body integrates a clamping part, a clamping clamp, a connecting arm, and a fixing plate. The clamping clamp fits tightly against the roof structure to ensure a firm fixation. The L-shaped connecting arm cleverly connects the top of the clamping part to the fixing plate, not only enhancing overall rigidity but also providing flexible sliding space for the bolts. The T-shaped groove formed by the relative splicing of the installation notches of the two clamping bodies is specifically designed to accommodate and guide the bolt head, allowing the bolt to slide freely within the groove and easily adjust its position, greatly improving installation efficiency and adaptability. The above design simplifies the installation steps, reduces construction difficulty, and ensures the stable connection of additional equipment (such as decorative components, photovoltaic systems, etc.) on the metal roof, promoting the diversification and intelligent development of building functions. It represents a significant advancement in metal roof connection technology in the modern building field. Attached Figure Description

[0022] This utility model provides a metal roof conversion connection clamp. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. In the description of this utility model, it should be understood that the terms "up, down, left, right," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and should not be construed as limiting this utility model; in addition, the terms "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] Please see Figures 1 to 6This utility model provides a metal roof conversion connection clamp, including a pair of symmetrically arranged clamping bodies. Each clamping body includes a clamping part 1, a clamping part 2, a connecting arm 3, and a fixing plate 4. The clamping part 2 is connected to the bottom end of the clamping part 1 and is used to clamp and fix the roof structure. The connecting arm 3 is L-shaped, with one end connected to the top end of the clamping part 1 and the other end connected to the fixing plate 4. The connecting arm 3 and the fixing plate 4 form an installation notch, and the installation notches of the two clamping bodies are joined together to form a T-shaped groove 5. The T-shaped groove 5 is used to accommodate the head of the bolt connecting the two clamping bodies, so that the bolt can slide and adjust its position within the groove. That is, when the two clamping bodies are placed opposite each other, their installation notches are joined together to form a continuous T-shaped groove 5. The cross-section of the T-shaped groove 5 is inverted T-shaped with the groove opening facing inward, used to accommodate the head of the T-bolt connecting the two clamping bodies. The bolt head can slide freely along the length of the T-slot 5, thereby enabling continuous adjustment of the relative position of the two clamping bodies. Once the position is determined, the bolt is locked in place by tightening the nut.

[0024] The inner wall of the clamping part 2 is provided with anti-slip teeth 6, which extend along the clamping direction. Optionally, the cross-section of the anti-slip teeth 6 can be triangular, trapezoidal, or wavy, and can be manufactured by stamping, milling, or directly forming in a mold. When the clamping part 2 is tightened, the anti-slip teeth 6 bite into the surface of the roof structure, increasing the static friction of the contact surface and effectively preventing the clamp from sliding longitudinally or laterally along the roof structure.

[0025] The thickness of the clamping part 2 gradually decreases from its connecting end to the clamping part 1 towards the free end, forming a wedge-shaped structure. The thickness of the clamping part 2 is designed to be gradually varied, and it can be integrally formed during casting or stamping through mold design. When a fastening force is applied, the wedge-shaped structure makes the clamping part 2 more prone to elastic deformation, thereby tightly fitting the roof structure surface, improving the uniformity of clamping and the reliability of fastening.

[0026] Optionally, the clamping part 1 has at least one fastening screw hole. Specifically, the screw hole can be made by drilling and tapping or by using self-tapping threading technology. The fastening screw hole is used to screw in bolts or screws to tighten the roof structure from the side, thereby enhancing the clamping force, or to install other auxiliary fasteners. Multiple fastening screw holes can be provided as needed, arranged along the height direction of the clamping part 1.

[0027] Specifically, it also includes an anti-detachment block 7, which is integrally formed at the bottom edge of the fixing plate 4. The anti-detachment block 7 is set perpendicular to the fixing plate 4, and the anti-detachment blocks 7 of the two clamping bodies are arranged opposite each other and located at the two sides of the T-slot opening, forming a limiting structure for the bolt head. It can be understood that when the two clamping bodies are assembled, their anti-detachment blocks 7 are arranged opposite each other and located at the two sides of the T-slot opening edge, forming a pair of blocking structures. The height of the anti-detachment block 7 is slightly higher than the thickness of the bolt head, allowing the bolt head to slide in the slot, but preventing it from accidentally coming out vertically from the slot opening, thus enhancing safety.

[0028] The top surface of the fixing plate 4 is provided with serrated anti-slip texture 8, which extends along the length of the fixing plate 4. In this embodiment, the anti-slip texture 8 can be made by knurling, milling, or stamping processes, and the texture cross-section is sharp or smooth serrated. This anti-slip texture 8 can significantly increase the coefficient of friction between the fixing plate 4 and the upper component base, prevent relative slippage under vibration or load, and ensure connection stability.

[0029] Please see Figure 4 This image demonstrates how the coupling clamp is secured to a standing seam metal roof. The metal roof consists of a series of parallel metal panels, each connected to the other by a seam technique. As shown in the image, the coupling clamp is mounted on the metal panels using specific fasteners, ensuring a secure connection between the clamp and the roof. The coupling clamp allows for installation without damaging the seam structure of the metal panels and without harming the original roof structure.

[0030] Please see Figure 5 Connecting clamps are used to secure the external decorative joists. The joists are the frame structure used to support decorative panels or other covering materials. The diagram shows multiple connecting clamps installed along the length of the joists. Each clamp is connected to the metal roof via fasteners, ensuring the stability and strength of the joists while also facilitating the installation and adjustment of the decorative panels. In situations where decorative covering materials are added to metal roofs, such as the facade cladding of commercial buildings, this not only provides structural support but also helps enhance the building's aesthetics and functionality.

[0031] Please see Figure 6 This image demonstrates how connecting clamps are used to secure lifeline systems, safety devices designed to prevent falls while working at heights. As shown, the connecting clamps are mounted on a metal roof using specific fasteners and connected to the lifeline system, ensuring the stability and reliability of the lifeline and providing essential safety for workers at heights. In situations requiring work at heights, such as construction, maintenance, or cleaning, they provide a safe working platform, reducing the risks associated with working at heights.

[0032] In summary, this utility model of a metal roof conversion connection clamp, through its completely symmetrical double-clamping main body design, fundamentally solves the drawbacks of traditional asymmetrical clamps that require separate production, inventory, and installation of left and right parts. A single set of molds and processes can achieve mass production, significantly reducing production costs and improving processing efficiency. During on-site construction, any two main bodies can be quickly paired and assembled without the need to identify directions, greatly simplifying the installation process and reducing construction errors. The T-groove 5 structure formed by the L-shaped connecting arm 3 and the fixing plate 4 allows the bolt head to be embedded in the groove and slide freely longitudinally, achieving continuous stepless adjustment of the connection position and completely eliminating the need for... The limitations of traditional fixed hole positions on installation accuracy can be flexibly adapted to the spacing requirements of different external facilities and on-site construction deviations, greatly enhancing the versatility and compatibility of the clamp. Meanwhile, the concealed bolt design effectively avoids spatial interference and safety hazards caused by exposed bolt heads, making the overall structure more compact and rational. The clamping part 2's interlocking fixation with the roof structure ensures the clamp's fit to the roof and the uniformity of load transfer. Combined with the force balance characteristics brought by the symmetrical structure, it significantly improves clamping stability and long-term safety and reliability, truly achieving an organic unity of standardized manufacturing, convenient installation, flexible adjustment, and stable performance. Therefore, this utility model effectively overcomes the various shortcomings of existing technologies and has high industrial application value.

[0033] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of this utility model.
