Abstract
Description
Technical Field
[0001] This utility model relates to the field of building roofing engineering technology, and in particular to a roof panel with a diversion function. Background Technology
[0002] In the field of building roofing engineering, the traditional method for waterproofing and drainage of structures protruding from the roof (such as skylights on the roof, hereinafter referred to as protruding structures) is to use drainage channels on the roof panels on both sides of the protruding structure to collect and drain rainwater from the top of the protruding structure, preventing rainwater from accumulating on both sides of the protruding structure and reducing the risk of leakage between the protruding structure and the roof panels.
[0003] However, when the span of the protruding structure (i.e. the horizontal width of the top of the protruding structure) is large or the rainfall is heavy, the rainwater at the top of the protruding structure will flow to the roof panels on both sides because the drainage channels of the adjacent roof panels are not connected. The two roof panels next to the protruding structure alone are not enough to divert the large amount of water from the multiple roof panels at the top of the protruding structure in a timely and effective manner, resulting in the rainwater in the drainage channels of the roof panels at the top of the protruding structure and on both sides of the protruding structure remaining at a high level.
[0004] Over time, a large amount of water accumulates at the top of the protruding structure, causing continuous soaking and pressure on the roof's waterproofing layer, accelerating its aging and damage. It can also seep through tiny cracks and holes in the waterproofing layer to the area beneath the roof, leading to leaks. These leaks not only damage the building's interior finishes and equipment, affecting its normal functionality, but in severe cases, can even endanger the building's structural safety, causing significant economic losses and inconvenience to the owner. Therefore, there is an urgent need to develop a more effective waterproofing and drainage solution for the top of protruding structures to address these complex and serious engineering problems. Utility Model Content
[0005] This invention addresses the shortcomings of existing technologies by providing a roof panel with a diversion function that reduces the likelihood of excessive water accumulation at the top and sides of the protruding structure.
[0006] To achieve the above objectives, this utility model first proposes a roof panel with a drainage function, including a roof panel body, a water-blocking patch, and drainage accessories. The roof panel body includes a base plate and fixing fasteners located on the left and right sides of the base plate and protruding from the base plate. The fixing fasteners on both sides and the base plate enclose a drainage channel. Each fixing fastener of an adjacent roof panel body has at least one matching reserved opening. The water-blocking patch and drainage accessories are matched to the size of the reserved openings. In the assembled state, adjacent roof panel bodies are connected to each other through the fixing fasteners, and the reserved openings of adjacent roof panel bodies are interconnected. After assembly, the roof panel body has a water-blocking patch or drainage accessory sealed at the reserved opening. When the water-blocking patch is installed on the reserved opening, the water-blocking patch closes the reserved opening, and the drainage channels of adjacent roof panel bodies are not connected. When the drainage accessory is installed on the reserved opening, the drainage accessory opens the drainage channels of adjacent roof panel bodies.
[0007] In this embodiment, the roof panel body includes a roof panel body with a reserved opening only on the left side fixing fastener, a roof panel body with a reserved opening only on the right side fixing fastener, and a roof panel body with reserved openings on both sides fixing fasteners.
[0008] In this embodiment, the fixing fastener includes a retaining edge and a first buckle fixed to the top of the retaining edge. The length of the retaining edge matches the length of the base plate, and the first buckles on both retaining edges are mating snap fasteners.
[0009] In this embodiment, both the retaining edge and the first buckle are provided with openings to form reserved openings.
[0010] In this embodiment, the water-blocking patch includes a right half-panel and a left half-panel. The top of both the right and left half-panels is provided with a second buckle that matches the first buckle. The second buckles on the right and left half-panels can be snapped onto the first buckle. The second buckles on the right and left half-panels are mutually matching male-female snaps. The right and left half-panels are interlocked by the second buckles, forming a water-blocking patch after assembly. The shape of the water-blocking patch matches the shape of the pre-reserved opening, and the water-blocking patch is larger than the pre-reserved opening, so that the portion of the water-blocking patch edge larger than the pre-reserved opening forms a ring of adhesive. The water-blocking patch has a sealing waterproof adhesive layer on the adhesive area. In the assembled state, while the right and left half-panels are interlocked by the second buckles, the two sides of the second buckles are snapped onto the first buckles on both sides of the pre-reserved opening. The water-blocking patch is sealed and fixedly connected to the edge of the pre-reserved opening by the sealing waterproof adhesive layer on the adhesive area.
[0011] In this embodiment, the diversion accessory includes a sealing plate and a guide block. The sealing plate includes a top plate and guide plates welded to the left and right sides of the top plate. The shape of the sealing plate matches the shape of the reserved opening. The sealing plate is larger than the reserved opening, so that the part of the edge of the sealing plate larger than the reserved opening forms a ring of adhesive. The sealing plate has a sealing and waterproof adhesive layer on the adhesive area. Guide blocks are fixed on both the front and rear sides of the top plate. A gap is provided between the two guide blocks to form a guide groove. The guide block has a second slot on the side facing the baffle that matches the baffle. The width of the second slot matches the thickness of the two baffles. In the assembled state, the diversion accessory is inserted into the baffles on both sides of the reserved opening through the second slots on the two guide blocks. The sealing plate is sealed and fixedly connected to the edge of the reserved opening through the sealing and waterproof adhesive layer on the adhesive area.
[0012] With the above structure, this utility model has the following advantages:
[0013] 1. This device has pre-reserved openings on the fixing fasteners on both sides of the roof panel body. The openings can be closed by installing water-blocking patches to prevent the drainage channels of adjacent roof panels from being connected; or diversion accessories can be installed to connect the drainage channels of adjacent roof panels. Through the above structure, the drainage connectivity between roof panels can be flexibly adjusted according to actual needs. Thus, the drainage channels of adjacent roof panels can be connected by installing diversion accessories as needed, increasing the drainage volume of the roof panels on both sides of the protruding structure, thereby reducing the probability of large amounts of water accumulating at the top and sides of the protruding structure, and reducing the risk of water seepage in weak parts of the waterproof layer due to water accumulation.
[0014] 2. The water-blocking patch and diversion fittings are all sealed to the reserved openings with a waterproof sealant layer. After installation, a waterproof sealant layer can be laid at the joints to effectively prevent rainwater from seeping through the gaps and ensure the waterproof effect of the roof.
[0015] 3. The roof panel body of this device is designed in various models and can be prefabricated in the factory. After being transported to the site, the appropriate model can be selected for installation according to the actual situation. This facilitates the flexible selection of the appropriate model for installation based on the location of the protruding structure on the roof and drainage requirements, thereby improving the convenience of construction and the rationality of the drainage system.
[0016] In summary, this device has a simple structure and low cost, increases the drainage of the roof panels on both sides of the protruding structure, reduces the probability of large water accumulation at the top and sides of the protruding structure, and reduces the risk of water seepage in weak parts of the waterproof layer due to water accumulation.

[0027] like Figures 1 to 5 As shown, a roof panel with diversion function includes a roof panel body 1. The roof panel body 1 includes a base plate 12 and fixing fasteners 11 disposed on both sides of the base plate 12 and protruding from the base plate 12. The fixing fasteners 11 on both sides and the base plate 12 enclose a drainage channel. The fixing fasteners 11 include a retaining edge and a first buckle fixed to the top of the retaining edge. The length of the retaining edge matches the length of the base plate 12. The first buckle is formed by bending the top of the retaining edge. The first buckles on both retaining edges are mating snap fasteners.
[0028] like Figure 2 , 3As shown, each adjacent roof panel body 1 has at least one matching reserved opening 13 on its corresponding fixing fastener 11. The reserved opening 13 includes an opening on the edge and an opening on the first buckle. In the assembled state, the adjacent roof panel bodies 1 are connected to each other through the fixing fastener 11, and the reserved openings 13 of the adjacent roof panel bodies 1 are interconnected. After assembly, the roof panel body 1 has a water-blocking patch 2 or a diversion accessory 3 sealed at the reserved opening 13. When the water-blocking patch 2 is installed on the reserved opening 13, the water-blocking patch 2 closes the reserved opening 13, and the drainage channels of the adjacent roof panel bodies 1 are not connected. When the diversion accessory 3 is installed on the reserved opening 13, the diversion accessory 3 opens the drainage channels of the adjacent roof panel bodies 1.
[0029] like Figure 4 , 5 As shown, the water-blocking patch 2 includes a right half-blocking patch 22 and a left half-blocking patch 23. The top of both the right half-blocking patch 22 and the left half-blocking patch 23 is provided with a second buckle 21 that matches the first buckle. The second buckles 21 on the right half-blocking patch 22 and the left half-blocking patch 23 are mating male and female buckles. The right half-blocking patch 22 and the left half-blocking patch 23 are snapped together by the second buckles 21. The right half-blocking patch 22 and the left half-blocking patch 23 are also snapped onto the first buckle by the second buckles 21. After the right half-blocking patch 22 and the left half-blocking patch 23 are snapped together, they form the water-blocking patch 2.
[0030] The shape of the water-blocking patch 2 matches the shape of the reserved opening 13, and the water-blocking patch 2 is larger than the reserved opening 13, so that the part of the edge of the water-blocking patch 2 that is larger than the reserved opening 13 forms a ring of glue application area. The water-blocking patch 2 has a sealing waterproof adhesive layer on the glue application area. In the assembled state, the right half of the patch and the left half of the patch are fastened to the first buckles on both sides of the reserved opening 13 by the second buckle. The water-blocking patch 2 is sealed and fixedly connected to the edge of the reserved opening 13 by the sealing waterproof adhesive layer on the glue application area.
[0031] like Figure 6 As shown, the diversion accessory 3 includes a sealing plate and a guide block 32. The sealing plate includes a top plate 34 and water guide plates 31 welded to the left and right sides of the top plate 34. The shape of the sealing plate matches the shape of the reserved opening 13. The sealing plate is larger than the reserved opening 13, so that the part of the edge of the sealing plate larger than the reserved opening 13 forms a ring of glue application area. The sealing plate has a sealing and waterproof glue layer on the glue application area. The sealing plate has guide blocks 32 fixed on both the front and rear sides of the top plate 34. A gap is provided between the two guide blocks 32 to form a guide groove. The guide block 32 has a second slot 33 that matches the baffle on the side facing the baffle. The width of the second slot 33 matches the thickness of the two baffles. In the assembled state, the diversion accessory 3 is inserted into the baffles on both sides of the reserved opening 13 through the second slots 33 on the two guide blocks 32. The sealing plate is sealed and fixedly connected to the edge of the reserved opening 13 through the sealing and waterproof glue layer on the glue application area.
[0032] like Figure 7 As shown, the roof panel body 1 of this application includes various models, specifically including a roof panel with a reserved opening 13 only on the left fixing fastener 11, a roof panel with a reserved opening 13 only on the right fixing fastener 11, and a roof panel with reserved openings 13 on both fixing fasteners 11.
[0033] The water-blocking patch 2 and the diversion accessory 3 are sealed to the reserved opening 13 by a sealing waterproof adhesive layer to prevent rainwater from leaking out of the gap.
[0034] Using the above structure, the construction process of this device is as follows:
[0035] First, prefabricate the normal roof panels and the roof panels with reserved openings 13 of this device in the factory. This device has multiple models, including roof panels with reserved openings 13 only on the left side, roof panels with reserved openings 13 only on the right side, and roof panels with reserved openings 13 on both sides. Then transport them to the site. During on-site construction, select the two sides of the protruding structure 4 on the roof for installation according to the position of the protruding structure 4. During installation, first determine the number of drainage channels that need to be interconnected in the horizontal direction of the roof panels. Determine the number of this device required based on the number of interconnected drainage channels. Then select different models of this device for installation. During installation, first connect the adjacent roof panel bodies 1 to each other with fixing fasteners 11 so that the reserved openings 13 of the adjacent roof panel bodies 1 are interconnected. Then, according to the design, install the water-blocking patch 2 or diversion accessory 3 at the position of the reserved opening 13. After installation, a sealing and waterproof layer can be laid at the joint where the water-blocking patch 2 is connected to the roof panel body 1 or the diversion accessory 3 is connected to the roof panel body 1 to improve the sealing effect.
[0036] When the span of the protruding structure is large or the rainfall is heavy, the rainwater at the top of the protruding structure will first flow towards the roof panels on both sides of the protruding structure. This causes the water level in the drainage channels near the roof panels on both sides of the protruding structure to rise rapidly. At this time, the water will flow from the high-water-level drainage channel to the low-water-level drainage channel through the diversion channel, achieving the effect of rapid diversion through multiple channels. This quickly diverts the water at the top and sides of the protruding structure, reducing the chance of water accumulation at the top and sides of the protruding structure, and reducing the risk of seepage from weak points such as tiny cracks and holes in the waterproof layer.
[0037] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
