Description

Technical Field

[0001] This utility model belongs to the field of roof waterproofing technology, and relates to a locking structure, particularly a roof vertical locking structure. Background Technology

[0002] The roof is not a single piece during construction; it has expansion joints. These joints allow adjacent roof panels to move relative to each other to accommodate misalignment caused by thermal expansion and contraction or ground settlement. After the roof is fixed, roof panels are laid to effectively prevent rainwater erosion. At the expansion joints, adjacent panels are connected, typically using a deformable cover plate. Waterproofing is required between the cover plate and the roof panels on either side, usually achieved through a base of supports. The roof panels are fixed to the supports, and angle steel is fixed to the supports to secure the cover plate. The outer edge of the cover plate covers the outer edge of the roof panels, creating a barrier. Simultaneously, sealants such as silicone and polyurethane, along with foam plugs, are used to seal the bolted areas on the supports and cover plate to enhance waterproofing performance.

[0003] This type of joint sealing waterproofing method has several problems during long-term use: 1. The sealing material is prone to aging and failure, leading to the risk of leakage at the joints. The expansion joint is the weakest link in roof waterproofing. Commonly used sealants such as silicone and polyurethane, as well as foam plugs, are prone to hardening and cracking under ultraviolet light and temperature cycling, resulting in waterproofing failure. 2. The design is complex and the cost is relatively high. The design nodes are relatively complex and the construction is cumbersome. The cost of two continuous support angle steels is relatively high. The cost of a standing seam roof expansion joint system can reach more than twice the cost of a regular roof. 3. Sudden changes in local stiffness can easily cause fatigue damage. According to the existing standing seam roof expansion joint nodes, there are two continuous support angle steels at the expansion joint. The stiffness at this point is relatively high, and the connection between the roof expansion cover and the support angle steel is rigidly fixed. It cannot expand and contract synchronously with the roof panel. Repeated temperature deformation can cause the seam connector to loosen or fatigue break. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a standing seam roofing structure. It solves the technical problem of improving the waterproofing performance of existing standing seam structures while reducing costs.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A standing seam roof structure is disclosed, wherein the roof has an expansion joint, and there are separate roof panels on both sides of the expansion joint. The standing seam structure includes a roof panel located above the expansion joint. Both sides of the roof panel have upwardly raised bends, which are respectively bent and sealed with the outer edges of the roof panels to form a seam. The height of the seam in the vertical direction is higher than the height of the top of the roof panel.

[0007] The standing seam structure of this application uses a large roof panel to directly cover the expansion joint. The outer edge of the roof panel is designed with a bend that is raised to a certain height. At the raised position, a bend and pressing treatment is performed between the bend and the outer edge of the roof panel to form a seam. The seam forms an integral whole between the roof panel and the roof panel to achieve a sealing effect. This achieves a seal with minimal material. Since the bend is raised, the height of the seam is at the highest point of the entire roof panel. When rainwater falls, it is directly drained away by the roof panel or roof panel. Even if there is accumulated rainwater, it will not be able to reach the seam. This is equivalent to the roof panel and the roof panel forming an integrated structure, and rainwater cannot penetrate through the seam. This design improves the sealing and waterproofing performance while reducing material costs.

[0008] In the above-mentioned type of roof standing seam structure, the roof panel has a drainage groove located near the seam.

[0009] The roof panel of this application is also designed with a drainage channel near the seam. The sunken design of the drainage channel further reduces the surface height on one side of the seam, which improves the water accumulation depth and drainage performance. This design makes it even more difficult for water to reach the seam, thus further improving the overall waterproof performance.

[0010] In the above-mentioned type of roof standing seam structure, the roof panel has a drainage slope at the seam.

[0011] Similarly, a drainage slope is designed on the other side of the lock seam on the roof panel. After passing through the drainage slope, rainwater is directly guided to overflow onto the roof panel, and there will be no water accumulation on one side of the roof panel, so the overall waterproof performance is guaranteed.

[0012] In the above-mentioned roof standing seam structure, the roof is fixed with roof supports on both sides of the expansion joint. The outer edge and the bent part of the roof panel extend above the roof supports and bend above the roof supports to form the aforementioned seam. The outer edge and part of the bent part of the roof panel are adapted to the roof supports.

[0013] This application fixes roof supports on the roof near both sides of the expansion joint. The roof supports can effectively support the expansion joint, effectively prevent the expansion joint from collapsing and deforming, and greatly improve the overall service life. At the same time, the roof supports have a certain height to ensure the protrusion height of the lock joint, ensuring that it will not come into contact with rainwater and improving waterproof performance.

[0014] In the above-mentioned roof standing seam structure, a supporting sheet metal part is fixed on the roof support. The upper end of the supporting sheet metal part is sandwiched between the outer edge of the roof panel and the bending part, and the above three are bent and seamed by a seam locking machine.

[0015] The roof support of this application has a fixed supporting sheet metal component. The supporting sheet metal component is directly embedded and bent into the roof panel and roof plate to form an integral part. It is directly integrated into the lock joint to support the lock joint. This can improve the strength of the lock joint and ensure the overall service life.

[0016] In the above-mentioned roof standing seam structure, the seam portion has a first bend and a second bend. The second bend is located outside the first bend. At the second bend, the protruding lengths of the outer edge of the bend portion, the outer edge of the supporting sheet metal, and the edge of the roof panel increase sequentially. The supporting sheet metal covers the outer edge of the bend portion, and the edge of the roof panel covers both the supporting sheet metal and the outer edge of the bend portion.

[0017] The seam has two bends, bend one and bend two. Bend one is the first bend, closer to the inside, and bend two is the second bend, closer to the outside. The second bend is designed so that the outer edge of the sheet metal protrudes outside the bend and covers it. The roof panel protrudes further than the supporting sheet metal and covers it. This design provides a double seal at the seam, eliminating any exposed gaps. This effectively prevents rainwater from entering directly and significantly improves the overall waterproof performance.

[0018] In the above-mentioned roof standing seam structure, the roof panel includes a roof expansion joint and two drainage joints. The two drainage joints are located on both sides of the roof expansion joint and are integrally formed with the roof expansion joint. The outer edge of the drainage joint extends upward to form the above-mentioned bending part. The bending part, the drainage part and the side of the roof expansion joint surround to form the above-mentioned drainage groove.

[0019] The roof panel is divided into an expansion joint and a drainage section. The expansion joint can expand and contract to accommodate the changes in the expansion joint. Drainage sections are set on both sides of the expansion joint. Rainwater coming down from the expansion joint can enter the drainage section and be discharged directly. This design is different from the old-fashioned method of diverting rainwater to the roof panel. The advantage of this design is that the water flow will not pass through the joint, so there is no risk of leakage, thus improving the overall waterproof performance.

[0020] In the above-mentioned type of roof standing seam structure, the roof expansion joint includes two symmetrically inclined top surfaces that are adjacent to each other.

[0021] The roof expansion joint is designed with a symmetrical and sloping top structure, similar to a roof structure, which can directly guide water to the drainage section and drain it away, with good water-draining performance.

[0022] In the above-mentioned roof standing seam structure, the width of the roof expansion joint is greater than the width of the expansion joint.

[0023] The roof expansion joint is wider than the expansion joint, allowing it to deform more effectively to accommodate the changes in the expansion joint.

[0024] In the above-mentioned roof standing seam structure, the roof panel is spaced apart from the roof surface.

[0025] The integral roof panel only contacts the roof panel and supporting sheet metal parts through the locking joint. There are no contact points between the roof panel and the roof surface. This design can effectively reduce the contact between the roof panel and the roof surface, reduce friction and wear, and at the same time, the roof panel can better adapt to the roof surface when the relative position changes, without causing unnecessary wear and deformation. This results in high connection strength and good durability.

[0026] The beneficial effects of this utility model are as follows: This upright locking structure uses a large roof panel to directly cover the expansion joint. The roof panel and the roof panel are bent and pressed to form a locking joint for sealing. The locking joint is raised to the highest point of the entire roof panel, so rainwater cannot penetrate through the locking joint. This design greatly reduces the amount of material used while improving the sealing and waterproofing performance. Attached Figure Description

[0030] like Figures 1-2The roof 1 shown has an expansion joint 11. Each roof 1 on both sides of the expansion joint 11 is covered with an independent roof panel 2. The roof 1 includes a roof panel 3, which is located above the expansion joint 11. Both sides of the roof panel 3 have upwardly raised bends 31. The bends 31 on both sides are bent and sealed with the outer edges of the roof panels 2 on both sides to form a locking part 4. The height of the locking part 4 in the vertical direction is higher than the height of the top of the roof panel 3. The vertical locking structure of this application uses a large roof panel 3 to directly cover the expansion joint 11. The outer edge of the roof panel 3 is designed with a bend 31, which is raised to a certain height. At the raised position, it is bent and pressed between the roof panel 2 and the outer edge to form a locking part 4. The locking part 4 forms an integral seal between the roof panel 2 and the roof panel 3, thus achieving a seal with minimal material. Since the bend 31 is raised, the height of the locking part 4 is at the highest point of the entire roof panel 3. When rainwater falls, it is directly drained away through the roof panel 3 or the roof panel 2. Even if there is accumulated rainwater, it cannot reach the locking part 4. This is equivalent to the roof panel 3 and the roof panel 2 forming an integral structure, and rainwater cannot penetrate through the locking part 4. This design improves the sealing and waterproofing performance while reducing material costs.

[0031] Furthermore, the roof panel 3 has a recessed drainage channel 32 near the seam 4. The roof panel 3 of this application also features a drainage channel 32 near the seam 4. The recessed design of the drainage channel 32 further reduces the surface height on one side of the seam 4, improving both water depth and drainage performance. This design prevents water from reaching the seam 4, further enhancing the overall waterproofing performance. Furthermore, the roof panel 2 forms a drainage slope 21 at the seam 4. Similarly, a drainage slope 21 is designed on the other side of the seam 4 on the roof panel 2. Rainwater, after passing through the drainage slope 21, is directly guided towards the roof panel 2 to overflow, preventing water accumulation on one side of the roof panel 2, thus ensuring overall waterproofing performance. The specific structure of the roof panel 3 is as follows: The roof panel 3 includes a roof expansion joint 33 and two drainage joints 34. The two drainage joints 34 are located on both sides of the roof expansion joint 33 and are integrally formed with the roof expansion joint 33. The outer edge of the drainage joint 34 extends upward to form the aforementioned bending part 31. The bending part 31, the drainage part 34, and the side of the roof expansion joint 33 surround to form the aforementioned drainage groove 32. The roof panel 3 is divided into the roof expansion joint 33 and the drainage joints 34. The roof expansion joint 33 can expand and contract to adapt to the changes in the expansion joint 11. Drainage joints 34 are provided on both sides of the roof expansion joint 33. Rainwater coming down from the roof expansion joint 33 can enter the drainage joints 34 and be directly discharged. This design, which differs from the old method of diverting rainwater to the roof panel 2, has the advantage that the water flow will not pass through the locking joint 4, thus eliminating the risk of leakage and improving the overall waterproof performance. The roof expansion joint 33 includes two symmetrically inclined top surfaces that are adjacent to each other. The roof expansion joint 33 is designed with a symmetrical, sloping top surface structure, similar to a roof structure, which can directly guide water to the drainage section 34 for discharge, providing good drainage performance. Preferably, the width of the roof expansion joint 33 is greater than the width of the expansion joint 11. The overall width of the roof expansion joint 33 is large, greater than the width of the expansion joint 11, so the wide roof expansion joint 33 can better deform to adapt to the changes in the expansion joint 11.

[0032] Furthermore, the roof panel 3 is spaced apart from the roof surface 1. The roof panel 3 only contacts the roof panel 2 and the supporting sheet metal 6 through the locking joint 4. There are no contact points between the roof panel 3 and the roof surface 1. This design effectively reduces the contact between the roof panel 3 and the roof surface 1, reducing friction and wear. At the same time, when the relative position of the roof surface 1 changes, the roof panel 3 can better adapt to it without unnecessary wear and deformation. This results in high connection strength and good durability.

[0033] Furthermore, roof supports 5 are fixed on both sides of the roof 1 near the expansion joint 11. The outer edge and bending portion 31 of the roof panel 2 extend above the roof supports 5 and bend above the roof supports 5 to form the aforementioned locking portion 4. The outer edge and partial outline of the bending portion 31 of the roof panel 2 are adapted to the roof supports 5. In this application, roof supports 5 are fixed on the roof 1 near both sides of the expansion joint 11. The roof supports 5 can effectively support the expansion joint 11, effectively preventing the expansion joint 11 from collapsing and deforming, and can significantly improve the overall service life. At the same time, the roof supports 5 have a certain height, which can ensure the protrusion height of the locking portion 4, ensuring that it will not come into contact with rainwater, thus improving the waterproof performance.

[0034] Furthermore, a supporting sheet metal part 6 is fixed on the roof support 5. The upper end of the supporting sheet metal part 6 is sandwiched between the outer edge of the roof panel 2 and the bending part 31, and the above three are bent and locked 360° by a locking machine, resulting in a good sealing effect. The supporting sheet metal part 6 is fixed on the roof support 5 of this application. The supporting sheet metal part 6 is directly embedded and bent into the roof panel 2 and roof plate 3 to form an integral part, directly integrating into the locking part 4 to support the locking part 4. This improves the strength of the locking part 4 and ensures the overall service life. The locking machine is a mature existing technology and will not be elaborated on further here.

[0035] Furthermore, the locking part 4 has a first bend 41 and a second bend 42. The second bend 42 is located outside the first bend 41. At the second bend 42, the protruding lengths of the outer edge of the bend 31, the outer edge of the supporting sheet metal 6, and the edge of the roof panel 2 increase sequentially. The supporting sheet metal 6 covers the outer edge of the bend 31, and the edge of the roof panel 2 covers the supporting sheet metal 6 and the outer edge of the bend 31. The four seam sections have two bends, namely bend 1 (41) and bend 2 (42). Bend 1 (41) is the first bend near the inside, and bend 2 (42) is the second bend near the outside. The second bend is designed so that the outer edge of the sheet metal part protrudes outside the bend section 31 and covers the bend section 31. The roof panel 2 protrudes further than the supporting sheet metal part 6 and covers the supporting sheet metal part 6. This design can provide double sealing at the gaps and eliminate exposed gaps, which can effectively prevent rainwater from entering directly and effectively improve the overall waterproof performance.
