Background

The discharge flue in a building is a vertical duct work used to remove kitchen fumes or toilet exhaust gases. The combined type discharge flue in the existing building is mostly assembled into a vertical pipeline by four side plates, most of the pipelines are rectangular, and smoke is discharged into the pipeline and then upwards discharged from the pipeline.

In order to facilitate the installation of an inner exhaust flue of a building, the edges of four side plates are adhered together by using inorganic cement, then the vertical pipelines are butted and installed, the butted and installed positions are generally located at floors of upper and lower floors, and concrete is poured outside the butted position of the walls of exhaust flues after the two pipelines are butted and installed.

Because the temperature of the smoke discharged by a kitchen is higher, and the bonding area of the side plates is smaller, the bonding part of the side plates is easy to crack in the using process, and smoke leakage of a flue is caused.

When the upper and lower two exhaust ducts are in vertical butt joint, the edges of the upper and lower two ducts are usually bonded together by using inorganic cement paste, and then cement is poured, but when a gap appears at the bonding position of the vertical butt joint, although the outer side can be used for pouring concrete to wrap the exhaust duct, one side or two sides close to the wall body cannot be wrapped by pouring concrete, and smoke leakage still exists.

Prior patent 200920044078.8 discloses a high strength flue gas flue, and this patent is in order to improve the intensity and the bearing capacity of flue gas flue, is equipped with the strengthening rib at the inboard four corners of flue gas flue, connects adjacent curb plate. However, although the stability of the four side plates of the flue gas duct is enhanced by the method, the tightness of no leakage of flue gas of the four side plates of the flue gas duct is not ensured, the problem of smoke leakage at the joint of the upper and lower pipelines cannot be solved, and the manufacturing and installation processes are complex and inconvenient to manufacture and install.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the technical problem that needs to solve provides a kitchen guarding's discharge flue is prevented leaking to concatenation formula, and increase curb plate bonding area has strengthened the tightness that prevents the flue gas leakage of four sides curb plate, also can prevent simultaneously that two flues butt joint department from leaking the cigarette, can also improve flue preparation installation effectiveness.

In order to solve the technical problem, the utility model adopts the following technical proposal.

A spliced leakage-proof kitchen and toilet discharge flue comprises four side plates which are mutually enclosed and adjacent side edges of the four side plates are fixedly connected into a vertical pipeline; the vertical edges of two sides of the inner end face of one group of the opposite side plates are respectively provided with a step groove, and the other two opposite side plates are embedded in the step grooves.

According to the spliced leakage-proof kitchen and toilet discharge flue, the inner wall of the top end of the side plate is provided with the socket piece which is used for connecting the upper pipeline and the lower pipeline and preventing smoke from overflowing and leaking from the joint of the upper pipeline and the lower pipeline.

Above-mentioned kitchen guarding's discharge flue is prevented leaking by concatenation formula, the socket joint spare is two and sets up, is the bearing and inserting board of L type structure along two adjacent curb plates directions of discharge flue.

Above-mentioned kitchen guarding's discharge flue is prevented leaking by concatenation formula, the socket joint spare is three and splices into the socket joint board of U type structure.

Above-mentioned kitchen guarding's discharge flue is prevented leaking by concatenation formula, the socket joint spare is the socket plate of four block combination rectangle structures.

Above-mentioned concatenation formula is prevented leaking kitchen guarding discharge flue, the width of one of them limit of ladder groove is the same with the thickness of side plate.

Due to the adoption of the technical scheme, the utility model has the following technical progress.

The side plates of the patent technology of the utility model are connected in a stepped way, so that the bonding area of the side plates is increased, the connecting strength of the side plates is increased, and the smoke leakage between the adjacent side plates of a single pipeline can be effectively prevented; the upper pipeline and the lower pipeline are connected through the socket piece, so that a gap between the upper pipeline and the lower pipeline is avoided, the connecting strength between the pipelines is improved, and the smoke leakage problem between the upper pipeline and the lower pipeline is further avoided; thereby realizing the leakage-free smoke discharge of the discharge flue.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

A spliced anti-leakage kitchen and toilet discharge flue is structurally shown in figures 1-2 and comprises four side plates 1, wherein the four side plates 1 are arranged, the four side plates 1 are mutually enclosed, and adjacent sides are fixedly connected into a vertical pipeline. The vertical edges of two sides of the end face of the inner side of one group of the oppositely arranged side plates are respectively provided with a step groove 3, and the other two opposite side plates 1 are embedded in the step grooves 3.

The width of ladder groove 3 is the same with the thickness of curb plate 1, and the curb plate can be complete inlay the dress in the ladder groove like this, can not appear the gap when the concatenation.

When the concatenation flue, use inorganic mucilage to bond four blocks of curb plates together, because the connection of adjacent curb plate is connected through ladder groove 3, increased the area of contact that adjacent curb plate bonded, at the in-process of using, the junction is difficult to the fracture, even receive the influence of high temperature flue gas, there is the fracture in the inner in ladder groove, the outer end in ladder groove also can be with the flue gas separation in the pipeline, the condition of leaking cigarette can not appear.
