Description

Technical Field

[0001] The utility model belongs to the field of building construction, and particularly relates to a roof assembled flue cap. Background Art

[0002] A roof flue is the top outlet of a flue for heating, ventilation, and smoke exhaust systems, typically located on a building's roof or ceiling. To prevent rainwater and debris from entering the flue and ensure smooth exhaust, a roof flue cap is installed on top of the flue. Currently, roof flue caps are typically constructed using brickwork or a single-step concrete pour. This involves complex construction processes, is time-consuming, and produces subpar results.

[0003] To address the above issues, patent document CN215331209U discloses a prefabricated roof flue for buildings. This method uses multiple flue sidewalls with an open upper portion to assemble the flue, and then adds a top cover plate on top to quickly construct the entire roof flue structure, effectively improving construction efficiency. However, this solution has some problems during its implementation: the flue structure has poor smoke exhaust performance, and rainwater, debris, etc. can easily enter the flue through the open upper portion of the flue sidewall; the flue structure has many assembly steps, and construction efficiency is slightly slow. Utility Model Content

[0004] The purpose of the utility model is to overcome the problem of low construction efficiency of existing roof flue caps and to provide a roof assembled flue cap with high construction efficiency and good smoke exhaust effect.

[0005] The utility model solves the technical problem by adopting the following technical solution: a roof-assembled flue cap, comprising a hollow base, a cylinder and a cover plate; the base is fixed to the roof, the base is located above the roof flue opening, the cylinder and the base are sleeved, the sleeve depth of the cylinder is 8-15 cm, the cylinder and the base are glued, the cover plate closes the upper end of the cylinder, the cover plate and the cylinder are fixed by a connecting piece, a wind hood is provided on the cover plate, and the wind hood is connected to the roof flue opening.

[0006] Optionally, the cylinder and cover plate are made of steel fiber foam concrete.

[0007] Optionally, the base is cast on the roof, the longitudinal section of the base wall is "L"-shaped, the outer wall of the base forms a horizontal step, the lower end face of the cylinder is placed on the horizontal step, the gap between the cylinder and the base is filled with epoxy resin, and the cylinder and the base are fixed by epoxy resin.

[0008] Optionally, an outwardly extending water guide plate is provided at the lower end of the cylinder, and a drip line is provided on the water guide plate.

[0009] The usage and principle of the present invention: The base of the present invention is cast together with the roof when the roof is cast, the outer wall of the base is smoothed with cement mortar, and the cylinder and cover are centrally processed into prefabricated components in the factory. During installation, the cylinder is sleeved with the base and fixed with epoxy resin or other bonding agents, the cover is placed on the upper end of the cylinder, the upper end of the cylinder is sealed, and then the cover is fixed to the cylinder with a connector, and the roof flue cap is installed. The entire implementation process is simple and fast, and the construction efficiency is very high; after the construction of the roof flue cap is completed, when the hood rotates, the smoke can enter the hollow base through the roof flue port, and then pass through the cylinder and be quickly discharged through the hood, with a better exhaust effect; in addition, due to the use of pre-assembled components, the structure is consistent, and the roof viewing angle is very regular.

[0010] Compared with the prior art, the present invention has at least the following beneficial effects: the present invention has high construction efficiency and good smoke exhaust effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 This is a schematic diagram of the longitudinal section structure of the utility model;

[0012] The components in the accompanying drawings are marked as follows: base 1 , cylinder 2 , cover plate 3 , hood 4 , horizontal step 5 , and water guide plate 6 . DETAILED DESCRIPTION

[0013] Example 1, below combined Figure 1 To further illustrate the utility model, the roof-assembled flue cap includes a hollow base 1, a cylinder 2 and a cover plate 3. The base is a cube, the cylinder is a square cylinder, and the cover plate is square. The cylinder and the cover plate are made of steel fiber foam concrete. The base is fixed to the roof, and the base is located above the roof flue outlet. The cylinder and the base are socketed, and the sleeve depth of the cylinder is 8-15 cm. The cylinder and the base are glued together, and the cover plate closes the upper end of the cylinder. The cover plate and the cylinder are fixed by a connecting piece, and the connecting piece is an L-shaped plate, which connects the cover plate and the cylinder respectively and is fixed by bolts. A hood 4 is installed on the cover plate, and the installation position of the hood and the cover plate is sealed, and the hood is connected to the roof flue outlet.

[0014] In order to improve the connection stability between the cylinder and the base and improve the overall waterproof ability, the base is cast on the roof. The longitudinal section of the base wall is "L"-shaped. A horizontal step 5 is formed on the outer wall of the base. The horizontal step is leveled with cement mortar. The lower end face of the cylinder is placed on the horizontal step. The gap between the cylinder and the base is filled with epoxy resin. The cylinder and the base are fixed by epoxy resin. An extended water guide plate 6 is provided at the lower end of the cylinder, and a drip line is provided on the water guide plate.

[0015] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
