Description

[0002] Roof casing is the casing installed on the roof. The traditional anti-leakage plugging scheme is generally asphalt hemp plugging. However, in the implementation of construction, the traditional scheme has two shortcomings: First, due to the deviation of construction operation, the roof-penetrating pipe is inconsistent with the center line of the embedded casing after installation. The gap between the roof-penetrating pipe and the embedded casing is uneven. If it is too large, the plugging cannot be guaranteed to be dense, and if it is too small, it is difficult to operate; second, the roof construction method commonly includes structural floor, slope leveling, waterproof layer, insulation layer, surface layer and other structures. The vertical thickness is relatively large (greater than 300mm thick). It is difficult to achieve a long and dense degree of traditional asphalt hemp plugging, which is labor-intensive on site.

[0044] See also Figure 1 to Figure 2 As shown;

[0045] This embodiment discloses a roof casing waterproof plugging device, which is integrated in the roof casing, and the device includes:

[0046] Funnel structure 2; and

[0047] A water-shedding plate 3 located above the funnel structure 2;

[0048] The roof sleeve includes a pre-buried sleeve 101 and a roof sleeve 102 extending axially along the pre-buried sleeve 101 and passing through the pre-buried sleeve 101;

[0049] The funnel structure 2 is installed at the connection between the embedded sleeve 101 and the roof sleeve 102, and the lower end portion of the funnel structure 2 is embedded in the space between the embedded sleeve 101 and the roof sleeve 102 to inject anti-leakage plugging material into the space between the embedded sleeve 101 and the roof sleeve 102;

[0050] The upper end of the water-shedding plate 3 is fixedly connected to the outer wall of the roof casing 102 , and the outer contour projection area of ​​the water-shedding plate 3 is larger than the outer contour projection area of ​​the lower funnel structure 2 .

[0051] Specifically, the present embodiment discloses a waterproof plugging device for a roof sleeve, which is integrated on the roof sleeve. The roof sleeve involved in the present embodiment includes a pre-embedded sleeve 101 and a roof sleeve 102; the plugging device of the present embodiment includes a funnel structure 2 and a water drop board 3; wherein the funnel structure 2 is arranged at the connection between the pre-embedded sleeve 101 and the roof sleeve 102, and is used to pour anti-leakage plugging materials into the space between the pre-embedded sleeve 101 and the roof sleeve 102; the present embodiment arranges a water drop board 3 above the funnel structure 2. The water drop board 3 of the present embodiment is an "umbrella" structure covered above the funnel structure 2, and its outer contour projection area is larger than the outer contour projection area of ​​the lower funnel structure 2, and mainly plays the role of receiving rainwater and evacuating it; the lower funnel structure 2 is mainly used for anti-leakage plugging, and the sealing plugging material can be smoothly poured into the corresponding space in the form of a funnel.

[0052] Preferably, the embedded sleeve 101 of this embodiment is partially embedded in the roof building foundation, and the outer wall of the lower part of the embedded sleeve 101 protrudes toward the outer peripheral side to form a water stop wing ring 103;

[0053] A hanging mold 104 is provided at a position where the roof building foundation cooperates with the lower end of the embedded sleeve 101, and the hanging mold 104 supports the embedded sleeve 101;

[0054] The lower portion of the roof sleeve 102 passes through the hanging formwork mold 104 .

[0055] First, this embodiment defines the structure of the embedded sleeve 101 and the roof sleeve 102, and a hanging mold 104 is provided at the lower end of the embedded sleeve 101 to support the embedded sleeve 101 and connect the embedded sleeve 101 with the roof building foundation, and a water stop wing ring 103 is provided on the outer part of the lower part of the embedded sleeve 101. Finally, the roof sleeve 102 can be installed.

[0056] Preferably, the funnel structure 2 of this embodiment includes:

[0057] Cone portion 201; and

[0058] An embedded cylinder portion 202 formed at the lower end of the conical cylinder portion 201;

[0059] The embedded cylinder portion 202 is embedded in the space between the embedded sleeve 101 and the roof sleeve 102, and the conical cylinder portion 201 is located at the upper end of the embedded sleeve 101;

[0060] The conical cylinder portion 201 is configured as a structure in which the cross-sectional size gradually decreases from top to bottom;

[0061] The anti-leakage plugging material is poured into the space between the embedded sleeve 101 and the roof sleeve 102 , and into the cone portion 201 through the funnel structure 2 .

[0062] Among them, the anti-leakage plugging materials poured through the funnel structure 2 of this embodiment are divided into:

[0063] Grouting material 401 poured into the space between the embedded sleeve 101 and the roof sleeve 102; and

[0064] The non-curing rubber asphalt waterproof coating 402 is poured into the cone portion 201 .

[0065] Preferably, the water-shedding plate 3 of this embodiment is configured as a structure with a cross-sectional size gradually increasing from top to bottom;

[0066] The middle part of the water-shedding plate 3 is a cone-shaped structure, the upper end of the water-shedding plate 3 has a connecting portion 301, and the lower end of the water-shedding plate 3 has a vertical portion 302;

[0067] The connection portion 301 of the water-shedding plate 3 is connected to the roof sleeve 102 through the mounting structure 5 .

[0068] The mounting structure 5 of this embodiment includes:

[0069] Clamp 502 and expansion ring 501;

[0070] An expansion ring 501 is provided between the connection portion 301 of the sheathing plate 3 and the roof sleeve 102 , and the connection portion 301 is fixed to the roof sleeve 102 via a clamp 501 .

[0071] As an expanded implementation method, in order to improve the water-guiding effect of the water-shedding plate 3, the lower part of the conical structure of the water-shedding plate 3 of this embodiment overlaps the edge of the upper end of the funnel structure 2, and the elevation of the vertical part 302 is lower than the elevation of the upper end of the funnel structure 2.

[0072] In this embodiment, the "drainage" effect is fully exerted by the upper water-shedding plate 3. When rainwater flows vertically down along the outer wall of the roof pipe 102, the inner expansion ring 501 of the upper water-shedding plate 3 expands after encountering water, effectively blocking the fixed contact portion between the upper water-shedding plate 3 and the roof pipe 102; when rainwater falls directly onto the water-shedding plate 3, the upper water-shedding plate 3 takes the shape of an "umbrella", effectively evacuating the rainwater flowing onto it. Since the projection area of ​​its outer contour is larger than the projection area of ​​the outer contour of the lower funnel structure 2, it can ensure that rainwater will not be evacuated into the gap between the lower roof pipe 102 and the embedded sleeve 101. In addition, the anti-leakage sealing method in the lower funnel structure 2 achieves a waterproof effect.

[0073] In addition, this embodiment can fully play the role of "prevention" through the lower funnel structure 2. The funnel structure 2 is first sealed to the top of the embedded casing 101 with grouting material 401, and then asphalt waterproof coating is sealed 402 to the top of the funnel structure 2, which reduces the construction difficulty and can seal densely.

[0074] Finally, the material of the water-shedding plate 3 involved in this embodiment is preferably aluminum.

[0075] In the above technical scheme, the utility model provides a roof casing waterproof plugging device, which has the following beneficial effects:

[0076] The waterproof sealing device of the utility model adopts the means of upper dredging and lower waterproofing, and adopts a structure combining a water-shedding plate 3 and a funnel structure 2. The materials are selected from common building materials, the cost is controllable, the existing components work together, and there are no negligible elements. The overall device is easy to construct, has a good anti-leakage effect, and has a high success rate.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
