Problems solved by technology

[0003] The above-mentioned prefabricated flue has the following problems: (1) When installing the flue in a narrow environment such as kitchen and bathroom, sufficient installation space is required. Therefore, holes are generally reserved on the floor to be 50mm larger than the size of the flue. During the flue installation process, steel bars need to be placed at the lower part to share the load of each flue on the floor, but there is a hidden danger of corrosion of the steel bars
(2) After the flue is installed, the sealing quality of the hole position seriously affects the waterproof ability of the kitchen and bathroom, and because the flue and exhaust duct are often arranged near the corners, the quality of sealing on both sides of the wall cannot be guaranteed, which is harmful to the waterproofing of the kitchen and bathroom. (3) It is very difficult to deal with the gaps after the flue is assembled, and it is easy to cause quality problems such as smoke and oil flow, and there are many quality control points in the installation process

Abstract

The invention discloses an assembly type flue convenient to mount. The flue comprises multiple flue standard sections which are arranged up and down and provided with hollow middles, every two adjacent flue standard sections are connected through a middle connecting part, the flue standard section of each flue bottom section is sleeved with a bottom connecting part, each middle connecting part comprises a rectangular sleeve, a supporting plate with the middle provided with a smoke passing hole is arranged in each rectangular sleeve, each bottom connecting part comprises a rectangular outer cylinder, a rectangular supporting frame is arranged in the middle of each rectangular outer cylinder, and is transversely arranged, the outer edges of the four sides are arranged outside the rectangularouter cylinders, the inner walls are located in the rectangular outer cylinders, and an inner bearing part and an outer bearing part are formed in the inner side and the outer side of each rectangular outer cylinder correspondingly. The assembly type flue convenient to mount is convenient to assemble, the assembling efficiency can be effectively improved, and the flue smoke leakage can be prevented.

Description

technical field [0001] The invention relates to a building flue, in particular to an assembled flue which is easy to install. Background technique [0002] Existing high-rise buildings, especially the kitchens of residential buildings, will have flues installed. Generally speaking, the flue is in the shape of a rectangular column and is installed at the corner of the two walls. Traditional flues are all handmade by workers, but their wall thickness and strength cannot meet the requirements, and the quality is poor. With the continuous research and development of later personnel, most of the flues used by construction companies are connected by multi-section prefabricated flues. The flues made by this method have the advantages of good quality and high production efficiency. [0003] The above-mentioned prefabricated flue has the following problems: (1) When installing the flue in a narrow environment such as kitchen and bathroom, sufficient installation space is required. ...
