Description

Technical Field

[0001] The utility model relates to the technical field of roof ridge waterproofing, in particular to a roof ridge waterproofing and anti-leakage structure, in particular to a roof ridge waterproofing and anti-leakage structure in severe cold areas. Background Art

[0002] Metal roofing system is a common roofing structure. Although metal roofing is easy to make, install and has high strength, metal plates are greatly affected by temperature. When the temperature is low in cold areas, they are prone to expansion and contraction deformation, which leads to cracking and deformation of the interface, forming leakage hazards. Unreasonable early design of nodes such as height differences, joints between concrete structures and steel structures, and deformation joints can also easily lead to cracking and leakage at the nodes. Leakage of metal roofs will lead to corrosion of the main structure, a decrease in the structural bearing capacity, and a significant increase in the possibility of structural instability.

[0003] The ridge is an important structure on the roof. There are many joints and gaps at the ridge. The ridge is also the first structure to face rainwater. The ridge of the metal roof is also the area where water seepage mainly occurs. The existing technology mainly forms a waterproof structure at the ridge through a cover plate or waterproof membrane, which has a certain effect in the short term. However, after long-term use, there is still a great risk of water seepage and leakage, and the stability and integrity are poor. Summary of the invention

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as "middle", "upper", "lower", "left", "right", "inside" and "outside" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0026] like Figure 1 to Figure 4 As shown, a ridge waterproof and anti-leakage structure includes a roof and a ridge arranged on the roof, the roof is paved with a vertical lock-edge roof panel 1, and the ridge is provided with a shedding board 2 extending to both sides of the ridge, and the shedding board 2 blocks the gap at the top of the ridge; the shedding board 2 is also provided with a support plate 3 and a cover plate 4 extending to both sides of the ridge, the extension length of the support plate 3 is greater than the extension length of the shedding board 2, the shedding board 2 and the support plate 3 are respectively connected to the vertical edges 101 of the vertical lock-edge roof panel 1 through a plurality of clips, and a backflow block 5 is also provided between the vertical edges 101 arranged at intervals, the support plate 3 extends to the backflow block 5, the cover plate 4 extends beyond the position of the backflow block 5, and the cover plate 4 and the support plate 3 are also connected to the backflow block 5 through a connector 6.

[0027] The waterproof and anti-leakage structure of the roof ridge can greatly improve the waterproof performance of the roof ridge by arranging a shedding board 2, a support board 3 and a cover board 4 extending to both sides from the inside to the outside at the roof ridge, thereby preventing rainwater from penetrating downward from the gap at the roof ridge and enhancing the supporting strength and structural stability of the roof ridge.

[0028] The cover plate 4 serves as the first waterproof layer, allowing rainwater to flow directly onto the roof panels on both sides. The shedding board 2 arranged under the cover plate 4 can directly guide the water leaking from the shedding board to flow onto the roof panels; the support plate 3 is arranged between the two, has a supporting function, and can improve the connection support strength there.

[0029] The standing seam roof panel 1 has good installation performance and a good overall shape after assembly. It does not need to be fixed by perforating or gluing, and is only fixed on the support by the bite between the standing edges to form a closed waterproof whole.

[0030] The area between a pair of upright edges of the upright lock-seam roof panel 1 is a good drainage ditch, which is conducive to the downward flow of rainwater. However, the shedding board, support board and cover board cannot be directly laid on the bottom surface of the upright lock-seam roof panel, but can only be arranged along its upright edges. In order to facilitate the installation of the shedding board 2 and the support board 3 on the upright edge 101, the clamping piece is provided, which can allow the clamping piece to be directly clamped on the assembled upright edge 101, so as to connect the shedding board or the support board, and also clamp the adjacent upright edges.

[0031] In order to prevent rainwater from flowing back when the amount of rainwater is large, a backflow block 5 is added under the cover plate, that is, it is arranged between a pair of upright edges of the upright lock-edge roof panel; the arrangement of the backflow block 5 can also play a supporting role to support the support plate and the cover plate, and connect the three through a connecting piece to form a more stable structure.

[0032] The backflow block 5 does not completely seal the area when preventing rainwater from flowing back, but only blocks the backflow when the amount of water is large. Some water discharged by the sheathing board can be discharged downward through some gaps between the backflow block and the roof panel.

[0033] The large-angle obtuse structure of the roof ridge has symmetrical slopes on both sides, and the structures of the cover plate, the support plate and the shedding plate extending on both sides can also be laid on the roof ridge well without falling off.

[0034] Furthermore, the distance that the sheathing board 2 extends to the side of the ridge does not exceed 150 mm, and the distance that the cover board 4 extends to the side of the ridge is 300-400 mm, preferably around 350 mm. This size arrangement can achieve better waterproofing effect and better control costs.

[0035] Furthermore, the sheathing plate 2 is a hot-dip galvanized steel plate with a thickness of 1 mm, which has good corrosion resistance, and the support plate 3 is a stainless steel plate with a thickness of 3 mm. The cover plate 4 is made of the same material as the standing seam roof panel 1, both of which are aluminum-magnesium-manganese structural plates.

[0036] In the process of selecting metal roofing materials, commonly used metal alloy materials are aluminum-magnesium or aluminum-manganese. Among them, aluminum-manganese alloy cannot be strengthened by heat treatment. At the same time, as a deoxidizer, the increase in manganese content helps to improve the strength of the alloy without affecting the plasticity of the alloy. Magnesium can effectively improve the tensile properties of aluminum. For every 1% increase in magnesium content, the tensile strength of the alloy can be increased by about 34MPa. However, at the same time, too high magnesium content will affect the performance of the alloy. If it is at room temperature for a long time, softening and hot brittleness will occur, affecting the strength of the roof. Based on the actual local conditions in cold areas and the characteristics of wind pressure, aluminum-manganese-magnesium alloys with appropriately reduced magnesium content and appropriately increased manganese content are selected.

[0037] Furthermore, the clamping member includes a pair of elastic arms 7, and the elastic arms 7 have an arc-shaped clamping portion 701, a vertical clamping portion 702 and a guide portion 703 that are connected as one. The clamping members are distributed at intervals below the support plate or the water-shedding plate.

[0038] A pair of the elastic arms 7 can be clamped on the locked upright edges and can be connected to the shedding board or the support plate. The arc-shaped clamping portion 701 can be wrapped and clamped on the locking edge structure. The vertical clamping portion 702 can be clamped on the vertical part of the upright edge. The guide portion 703 is in the shape of a trumpet, which is convenient for plugging into the upright edge from above, or prying the elastic arms apart to both sides.

[0039] Furthermore, the elastic arm 7 is a metal spring sheet with good flexibility and strength. The metal spring sheet is welded to the support plate or under the water-shedding plate. The metal spring sheet is covered with a rubber sleeve, which can avoid pinching the upright edge and increase friction and clamping force.

[0040] In some embodiments, the elastic arm 7 may be a rubber arm, and a plurality of elastic metal wires are compounded in the rubber arm.

[0041] Furthermore, an arc-shaped locking edge 102 is provided above the vertical edge 101 on one side of the vertical lock-seam roof panel 1, and a locking head 103 is provided on the vertical edge on the other side. When the two vertical edges are fitted together, the locking head 103 is accommodated in the locking edge 102, and the connection is completed by locking the locking head 103 through the locking edge 102.

[0042] Further, such as Figure 5As shown, the roof includes a corrugated steel plate 9 arranged on the roof beam 8, the corrugated steel plate 9 is connected to the secondary purlin 11 through a support 10, the secondary purlin 11 is provided with a fixing seat 12, the upright lock seam roof panel 1 is arranged on the secondary purlin 11 and connected to the fixing seat 12, and the fixing seat 12 is inserted between adjacent upright edges 101; an insulation layer 13 with a thickness of 200 mm is also provided between the upright lock seam roof panel 1 and the corrugated steel plate 9.

[0043] This form can optimize the connection and installation structure of the roof, reduce the connection methods such as perforation and gluing, and improve the integrity. The fixing seat 12 is installed on the secondary purlin 11 to provide a fixing point for the vertical lock seam roof panel 1; the setting of the insulation layer 13 plays a role in heat insulation, and the secondary purlin 11 is located on the roof beam 8, and the roof beam is used to form a stable support structure.

[0044] Furthermore, the insulation layer 13 is rock wool, and a non-woven fabric layer is provided between the insulation layer 13 and the corrugated steel plate 9. A 1.5 mm TPO is provided on the insulation layer 13, which can drain rainwater into the gutter, further improving the waterproof and anti-seepage ability of the entire roof.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
