Abstract
Description
Technical Field
[0001] This utility model relates to the field of waterproofing technology for color steel plates, specifically to a steel structure color steel plate connection structure. Background Technology
[0002] Color steel sheets are widely used as roofing waterproofing structures. By laying color steel sheets, the roof can be fully covered, achieving purposes such as sun and rain protection. When laying color steel sheets, several small sheets are spliced together to form a continuous laying structure, achieving large-area coverage. Currently, common connection methods for connecting two color steel sheets include mechanical fastening, concealed fastening, interlocking connection, and the use of specific splicing structures.
[0003] In practical applications, simply using mechanical fastening connection structures can lead to problems such as screw corrosion and rust, and aging of rubber rings reducing sealing performance. Simply using snap-on or interlocking connections can reduce the exposure of screws, but requires precision machining of the color steel plate, which is costly, and is prone to gaps caused by minor deformation during installation, affecting the waterproof effect. On the other hand, some solutions using specific splicing structures cannot be widely used due to their limited application scenarios, high production costs, and complex construction processes.
[0004] It is evident that current color steel plate connection and laying schemes still have room for improvement. Optimization is needed to enhance the stability and reliability of the connection structure, while avoiding complex construction processes and increased operating costs. Efforts should be made to maximize construction convenience and efficiency. Therefore, a more reasonable technical solution is required to address the existing technical problems. Utility Model Content
[0005] To overcome at least one of the defects mentioned above, this utility model proposes a steel structure color steel plate connection structure. By improving the connection structure, the stability, reliability, and sealing effect of the color steel plate are enhanced, while reducing the complexity of construction, ensuring the stability and reliability of the structure, enabling convenient and rapid construction, and meeting construction requirements.
[0006] To achieve the above objectives, the connection structure disclosed in this utility model can adopt the following technical solution:
[0007] A steel structure color steel plate connection structure includes a support structure on which color steel plates are installed. The connecting edges of the color steel plates form an upwardly arched arc-shaped overlapping surface. The arc-shaped overlapping surfaces of two adjacent color steel plates overlap each other, and a sealing element is filled between the two arc-shaped overlapping surfaces. A fixed bracket is installed below the arc-shaped overlapping surface. The width of the fixed bracket is greater than the width of the arc-shaped overlapping surface. Several fasteners are installed on the color steel plates. The fasteners pass through the sealing element and the fixed bracket and are connected to the support structure.
[0008] The aforementioned color steel plate connection structure, by forming an upward-arched arc-shaped overlapping surface, can quickly guide rainwater from the overlapping surface to both sides, preventing water accumulation at the overlapping surface; the sealing of the arc-shaped overlapping surface is maintained by sealing components and fixed brackets, ensuring waterproof performance; at the same time, in conjunction with the fastener connection support structure, the overall stability and reliability of the color steel plate can be maintained.
[0009] Furthermore, the seal is used to fill the gap at the arc-shaped overlapping surface to prevent water leakage. Its structure is not uniquely limited; optimization is proposed here, and one feasible option is: the seal has an arc-shaped structure that fits the arc-shaped overlapping surface. When using the above solution, the thickness of the arc-shaped seal can be uniform; in some solutions, the thickness in the middle of the arc-shaped seal can be greater than the thickness at the edges.
[0010] Furthermore, to improve waterproofing, the wider the coverage area of the sealant, the better the waterproofing effect. Here, we propose an optimization and one feasible option: the width of the extended sealant is greater than or equal to the width of the arc-shaped overlap surface. When using the above solution, the sealant can be made of a flexible material.
[0011] Furthermore, the seal can be made of various materials and is not limited to one specific material. Here, we optimize the design and propose one feasible option: the seal is made of butyl rubber, or the surface of the seal is provided with a butyl rubber layer. When using the above solution, the surface of the seal has a waterproof structure, achieving a waterproof seal after filling.
[0012] Furthermore, the fixing bracket can be constructed in various forms, and its structure is not limited to a single one. Here, we optimize and propose one feasible option: the middle part of the fixing bracket arches upward and fits against the arc-shaped overlapping surface, and the edge of the fixing bracket extends to the supporting structure and cooperates with the supporting structure. When adopting the above scheme, the middle part of the fixing bracket can support the color steel plate to maintain the sealing of the arc-shaped overlapping surface, while the edge part of the fixing bracket can support the color steel plate to maintain the connection and cooperation with the supporting structure.
[0013] Furthermore, the fasteners used to connect and fix the color steel plate can be installed at multiple points. Here, we optimize the process and propose one feasible option: the fasteners pass sequentially through the color steel plate and the fixing bracket from the upper surface of the color steel plate, extending to connect to the supporting structure. When using this solution, the color steel plate and the fixing bracket are directly connected to the purlin.
[0014] Furthermore, the fasteners can be installed in even more locations. Here, we optimize the design and propose one feasible option: the fastener extends from the upper surface of the color steel plate, passing sequentially through the arc-shaped lap surface, the seal, the arc-shaped lap surface again, and the fixing bracket, connecting to the supporting structure. When using this solution, the fastener connects and fixes the arc-shaped lap surface, the seal, and the fixing bracket, ensuring stable connection and reliable sealing at the lap surface.
[0015] Furthermore, the support structure can adopt various schemes, and its structure is not limited to a single one. Here, we optimize and propose one feasible option: the support structure includes a support frame for laying the color steel plate. When adopting the above scheme, the support frame is erected over the entire area where the color steel plate is laid. Laying the color steel plate on the support frame can help improve the stability and reliability of the laid structure.
[0016] Furthermore, there are multiple options for the support frame structure, and its structure is not limited to a single one. Here, we optimize and propose one feasible option: the support frame includes several purlins, and the fasteners are connected to the purlins. When adopting the above solution, the purlins can be made of wood.
[0017] Furthermore, the purlins, when assembled, form a support frame. The purlins can extend in various directions, and their structure is not uniquely limited. Here, we propose one feasible option: the purlins extend along the width of the color steel plate, and the fasteners above the same purlin maintain a constant distance in the width direction after connecting to the purlin. With this solution, the purlins extend in the same direction as the width of the fixed bracket and the seal. When the middle and side edges of the fixed bracket are connected, the spacing between these connection points remains fixed, thus maintaining greater structural stability.
[0018] Compared with the prior art, some of the beneficial effects of the technical solution disclosed in this utility model include:
[0019] This invention adjusts the connection structure of the color steel plates, making the connected color steel plates form a more stable and reliable whole, improving their sun protection and waterproof performance. At the same time, it does not require specific design and treatment of the color steel plate structure, saving costs. In the actual construction process, it is simple to operate, efficient to construct, and can meet the needs of practical applications. Attached Figure Description
