Description

Technical Field

[0001] The invention relates to the technical field of roof flashing connection structures, and particularly proposes a connection structure for roof flashing arc-shaped components. Background Art

[0002] Roof flashing is an important structural measure in building waterproofing projects. It refers to the waterproof structure between the roof waterproof layer and the protruding components, that is, at the intersection of the roof and the vertical wall (such as parapet, chimney, pipe shaft, etc.), in order to prevent rainwater from leaking into the building along the intersection, a waterproof treatment method is adopted. By turning the waterproof layer up to a certain height along the vertical wall, a waterproof transition area is formed. This area is called roof flashing. Taking the flashing treatment of the parapet as an example, the roof is usually first poured with concrete at the connection position of the parapet and the roof. The flashing membrane is then laid on the entire roof and laid along the curved component to the parapet.

[0003] When laying waterproof membranes, gaps are likely to appear when the waterproof membranes are folded and laid on the edge of the parapet, causing water penetration. Therefore, metal strips are usually required to mechanically fix them, which can make the edges of the membranes fit more closely with the base layer and reduce the generation of gaps. Metal strips are usually driven directly into the parapet by screws. Due to long-term use, the deformation and corrosion of the metal strips and the edge of the flashing membrane will cause water leakage at the parapet and the roof. Therefore, it is difficult for users to judge under what circumstances the flashing function of the metal strips and the waterproof membrane will have problems. In addition, each replacement and installation of the metal strips requires multiple removal and insertion of screws, which greatly damages the overall structure of the parapet.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] A connection structure for arc-shaped roof flashing components, comprising a wall and a roof. Figure 1 It is a schematic diagram of the three-dimensional structure in which the arc-shaped components are installed between the wall and the roof.

[0030] like Figure 1-Figure 3 As shown, an arc-shaped concrete waterproofing member 1 is cast at the connection position of the wall and the roof, and the wall and the roof are just tangent to the arc edge of the waterproofing member 1. The waterproofing membrane 2 is laid on the wall, the waterproofing member 1 and the roof surface, so that the waterproofing membrane 2 completely covers the roof. The waterproofing membrane 2 is attached to and extends to the height of the wall of not less than 250mm. Horizontal grooves 3 are opened on the inner sides of both walls, and the height of the horizontal grooves 3 is higher than the top height of the waterproofing membrane 2.

[0031] The waterproofing of walls and roofs is divided into two areas: the waterproofing area between the vertical wall and the roof, and the waterproofing area between two adjacent walls and roofs.

[0032] For waterproofing between the vertical wall and the roof, it includes a sealing component 1 and a sealing component 2 that are arranged at intervals. Both the sealing component 1 and the sealing component 2 can be metal parts with deformation ability.

[0033] like Figure 7 As shown, the sealing component 1 includes an integrally formed extrusion portion 4, an inclined portion 5, an extension portion 9 and a guide portion 10. The inclined portion 5 is arranged at the upper end of the extrusion portion 4, the extension portion 9 is horizontally arranged and also located at the upper end of the inclined portion 5, the guide portion 10 and the inclined portion 5 are respectively located on both sides of the extension portion 9, and the side of the extrusion portion 4 is also provided with an integrally formed reinforcement portion 16.

[0034] like Figure 6 As shown, the sealing component 2 includes an integrally formed drainage portion 7, a protective portion 8 and a bending portion 11. The drainage portion 7 is tilted and the top is against the wall. The bending portion 11 is arranged at the lower end of the drainage portion 7, and is bent toward the side close to the upper end. The protective portion 8 is arranged at the lower end of the bending portion 11. The lower half of the protective portion 8 is tilted, and the distance between its lowest end and the wall is greater than the distance between the upper end and the wall. The side of the protective portion 8 is also provided with a plurality of integrally formed pressure plates 15 arranged at equal distances.

[0035] like Figure 2-Figure 4 As shown, a transverse groove 3 and a mounting groove 12 are opened on the side of the wall. The mounting groove 12 is located below the transverse groove 3. A sideways U-shaped mounting frame 13 is assembled inside the mounting groove 12. A plurality of equidistant fixing plates 14 with threaded holes on the surface are welded inside the mounting frame 13.

[0036] When installing and using sealing component 1 and sealing component 2, the reinforcement part 16 is placed inside the mounting frame 13, so that the connection position of the extension part 9 and the inclined part 5 is placed inside the transverse groove 3, and then the pressure plate 15 is placed at the same horizontal height as the reinforcement part 16. At this time, the top of the drainage part 7 will be against the wall, and the bolt 17 is installed at the position of the protective part 8, so that the bolt 17 passes through the sealing component 2, the pressure plate 15, the sealing component 1 and the reinforcement part 16 in sequence until it is installed inside the fixed plate 14. Before installation, the operator can make holes in the corresponding positions on the surfaces of the pressure plate 15, the reinforcement part 16, the sealing component 1 and the sealing component 2 in advance.

[0037] When the bolt 17 rotates, it will drive the sealing component 1 and the sealing component 2 to gradually approach the wall. During this process, the edge of the bottom wall of the transverse groove 3 will squeeze the inclined portion 5, causing the inclined portion 5 to rotate close to the top of the inner wall of the transverse groove 3. The sealing strip 6 is bonded to the top of the extension portion 9, and the sealing strip 6 will rest against the top of the inner wall of the transverse groove 3, and become tighter and tighter to ensure the tightness of the overall seal. Similarly, the drainage portion 7 will also rest against the wall more and more tightly, and a curable sealant is applied between the drainage portion 7 and the wall to further ensure the sealing.

[0038] When the entire connection structure is in normal use, rainwater will fall from the surface of the drainage portion 7 to protect the waterproof membrane 2.

[0039] The pressure plate 15 forms a gap between the sealing component 1 and the sealing component 2. When the sealant ages and debonds over time, rainwater will flow down from between the drainage part 7 and the wall, and then fall on the surface of the guide part 10, forming a second layer of protection. Finally, it flows out from between the sealing component 1 and the sealing component 2. Therefore, the user can judge whether the sealant position is debonding and aging by the discharge position of the water flow, and then remove the old sealant and re-seal it.

[0040] An elastic extrusion strip 18 is bonded to the side of the extrusion portion 4, and an indentation is set in the middle of the extrusion strip 18. A plurality of grooves 19 are provided at the upper and lower ends of the extrusion strip 18 to ensure that the extrusion strip 18 has more space when deformed to avoid violent damage caused by excessive deformation pressure. The extrusion strip 18 is against the surface of the waterproof membrane 2. When the extrusion strip 18 is squeezed and fitted to the surface of the waterproof membrane 2, its elastic pressure can ensure that the top of the waterproof membrane 2 is more tightly connected to the wall.

[0041] For waterproofing between two adjacent walls and a roof, a sealing component three is included, which is also a metal part with deformation capability.

[0042] like Figure 4 and Figure 5 As shown, the sealing component three includes an L-shaped sealing component one and a fan-shaped sealing component two. The sealing strip 6 is L-shaped, and the sealing component one can completely fit in the corner of the wall. Similarly, the shape of the extrusion strip 18 is set to be L-shaped, completely fitting in the position of the wall, forming a covering extrusion on the waterproof membrane 2. The two sides of the sealing component one and the sealing component two are fixedly connected by the connecting plate 20. At this time, the sealing component one and the sealing component two are two integrated parts. Two limiting plates 21 are set on the surface of the connecting plate 20. The two limiting plates 21 are respectively against the top and bottom of the reinforcement part 16 to prevent the sealing component three from shifting during the installation process.

[0043] When installing sealing component three, first pre-install sealing component one and sealing component two on one side of the wall. The bolts 17 do not need to be tightened. At this time, place sealing component three in the corresponding position so that the two limit plates 21 are stuck above and below the reinforcement part 16. Then pre-install sealing component one and sealing component two on the adjacent wall. The operation is the same as before. Then gradually tighten each bolt 17. With the installation of sealing component one and sealing component two on both sides, sealing component three is also installed, and the sealing strip 6 at this position can also ensure sealing. It should be noted that the drainage part 7 on the sealing component three extends outward to contact the wall, and the extension surface is an inclined surface. The position in contact with the wall also needs to be applied with sealant.

[0044] In order to facilitate the staff to accurately judge whether the sealant is aging and peeling, a detection component is set between the sealing component one and the sealing component two.

[0045] like Figure 2 、 Figure 6 and Figure 7 The detection component includes a water-containing frame 23 symmetrically and obliquely arranged on both sides. The water-containing frame 23 is made of flexible material. The bottom of the extrusion part 4 and the protective part 8 are both provided with an integrally formed inner folding part 22. The two sides of the water-containing frame 23 are respectively against the opposite sides of the two inner folding parts 22. During normal use, the water-containing frame 23 is not placed between the sealing component 1 and the sealing component 2. When a water leakage detection is required, the water-containing frame 23 is pinched and placed between the two inner folding parts 22 so that the two sides are against the inner wall of the inner folding part 22. At this time, a large amount of water is poured at the position of the sealant. If the sealant is aged and debonded, the water will flow into the inside of the water-containing frame 23 and accumulate. Due to the characteristics of its flexible material, when the water weight reaches a certain level, the water-containing frame 23 will fall off, and the sealant needs to be reapplied at this time.
