Description

Technical Field

[0001] The invention relates to the technical field of roof flashing connection structures, and specifically 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 chimneys, pipe wells, 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 cast 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 the waterproof membrane, gaps are likely to appear when the waterproof membrane is folded and laid on the edge of the parapet, causing water penetration. Therefore, metal strips are usually required to mechanically fix it, which can make the edge of the membrane fit more closely with the base layer and reduce the generation of gaps. The metal strips are usually driven directly into the parapet with 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 between 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 the screws to be removed and driven in many times, which greatly damages the overall structure of the parapet.

[0004] To this end, the present invention provides a connection structure for arc-shaped roof flashing components. Summary of the invention

Specific embodiments

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

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

[0029] A connection structure for a roofing flashing arc member includes a wall and a roof, Figure 1 It is a three-dimensional structure diagram of the arc member installed between the wall and the roof.

[0030] As Figures 1-3 shown, an arc-shaped concrete waterproof part 1 is poured at the connection position between the wall and the roof. The wall and the roof are just tangent to the arc edge of the waterproof part 1. A waterproof coiled material 2 is laid on the surfaces of the wall, the waterproof part 1 and the roof, so that the waterproof coiled material 2 completely covers the roof. The height at which the waterproof coiled material 2 fits and extends to the wall is not less than 250 mm. 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 waterproof coiled material 2.

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

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

[0033] As Figure 7 shown, the first sealing component includes an integrally formed extrusion part 4, an inclined part 5, an extension part 9 and a diversion part 10. The inclined part 5 is arranged at the upper end of the extrusion part 4. The extension part 9 is horizontally arranged and is also located at the upper end of the inclined part 5. The diversion part 10 and the inclined part 5 are respectively located on both sides of the extension part 9. A reinforcing part 16 is integrally formed on the side surface of the extrusion part 4.

[0034] As Figure 6 shown, the second sealing component includes an integrally formed drainage part 7, a protection part 8 and a bending part 11. The drainage part 7 is inclined and its top abuts against the wall. The bending part 11 is arranged at the lower end of the drainage part 7 and bends towards the side close to the upper end. The protection part 8 is arranged at the lower end of the bending part 11. The lower half of the protection part 8 is inclined, and the distance from its lowest end to the wall is greater than the distance from its upper end to the wall. A plurality of equally spaced bearing plates 15 are integrally formed on the side surface of the protection part 8.

[0035] As Figures 2-4 shown, a horizontal groove 3 and a mounting groove 12 are formed on the side surface of the wall. The mounting groove 12 is located below the horizontal groove 3. A U-shaped mounting bracket 13 placed sideways is assembled inside the mounting groove 12. A plurality of equally spaced fixing plates 14 with threaded holes on their surfaces are welded inside the mounting bracket 13.

[0036] When installing and using the first sealing component and the second sealing component, place the reinforcing part 16 inside the mounting bracket 13 so that the connection position of the extension part 9 and the inclined part 5 is placed inside the horizontal groove 3. Then, press the bearing plate 15 against the same horizontal height as the reinforcing part 16. At this time, the top end of the drainage part 7 will abut against the wall. Install a bolt 17 at the position of the protection part 8 so that the bolt 17 passes through the second sealing component, the bearing plate 15, the first sealing component and the reinforcing part 16 in sequence until it is installed inside the fixing plate 14. Before installation, the operator can pre-drill holes at the corresponding positions on the surfaces of the bearing plate 15, the reinforcing part 16, the first sealing component and the second sealing component.

[0037] When the bolt 17 rotates, it will drive the first sealing component and the second sealing component to gradually approach the wall. During this process, the edge of the bottom wall of the transverse groove 3 will squeeze the inclined part 5, causing the inclined part 5 to rotate and approach the top inner wall of the transverse groove 3. A sealing strip 6 is adhered above the extension part 9, and the sealing strip 6 will abut against the top inner wall of the transverse groove 3 and become tighter and tighter, ensuring the tightness of the overall seal. Similarly, the drainage part 7 will also abut against the wall more and more tightly. Apply a curable sealant between the drainage part 7 and the wall surface to further ensure the sealing performance.

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

[0039] The bearing plate 15 forms a gap between the first sealing component and the second sealing component. When the sealant ages and debonds over time, rainwater will flow down between the drainage part 7 and the wall, and then fall on the surface of the diversion part 10. At this time, a second layer of protection is formed, and finally it flows out between the first sealing component and the second sealing component. Therefore, the user can judge whether the sealant is debonded and aged by the drainage position of the water flow, and then remove the old sealant and reapply the sealant for sealing.

[0040] Adhere an elastic extrusion strip 18 to the side of the extrusion part 4. The middle of the extrusion strip 18 is recessed, and a plurality of grooves 19 are opened at the upper and lower ends of the extrusion strip 18 to ensure that the extrusion strip 18 has more space during deformation and avoid violent damage caused by excessive deformation pressure. The extrusion strip 18 abuts against the surface of the waterproof coiled material 2. When the extrusion strip 18 is squeezed and fitted on the surface of the waterproof coiled material 2, its elastic pressure can ensure that the top of the waterproof coiled material 2 is more tightly connected to the wall.

[0041] For the waterproofing between two adjacent walls and the roof, it includes a third sealing component, and the third sealing component is also a metal part with deformation ability.

[0042] As Figure 4 and Figure 5 shown, the third sealing component includes an L-shaped first sealing component and a fan-shaped second sealing component. The sealing strip 6 is L-shaped. The first sealing component can completely fit at the corner of the wall. Similarly, the shape of the extrusion strip 18 is set to L-shaped and completely fits at the position of the wall to form a covering extrusion on the waterproof coiled material 2. The two sides of the first sealing component and the second sealing component are fixedly connected by a connecting plate 20. At this time, the first sealing component and the second sealing component are integrated. Two limiting plates 21 are arranged on the surface of the connecting plate 20, and the two limiting plates 21 respectively abut against the top and bottom of the reinforcing part 16 to prevent the third sealing component from shifting during the installation process.

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

[0044] In order to facilitate the staff to accurately judge whether the sealant at the position is aged and unsealed, a detection component is arranged between the first and second sealing components.

[0045] Such as Figure 2 、 Figure 6 And Figure 7 , the detection component includes water receiving frames 23 symmetrically and obliquely arranged on both sides. The water receiving frames 23 are made of flexible materials. Inner folding parts 22 are integrally formed at the bottoms of the extrusion part 4 and the protection part 8. The two sides of the water receiving frames 23 respectively abut against the opposite sides of the two inner folding parts 22. During normal use, the water receiving frames 23 are not placed between the first and second sealing components. When leakage detection is required, pinch up the water receiving frames 23 and place them between the two inner folding parts 22 so that both sides abut against the inner walls of the inner folding parts 22. At this time, pour a large amount of water at the position of the sealant. If the sealant is aged and unsealed, the water will flow into the interior of the water receiving frames 23 and accumulate. Due to the characteristics of its flexible material, when the weight of the water reaches a certain level, the water receiving frames 23 will fall off. At this time, the sealant needs to be reapplied.
