Embodiment 1

[0023] Refer to attached figure 1 , 2 , this embodiment is a single-hole flue gas channel, using more than two flue gas channel plates, which are matched and combined with each other to form a complete flue gas channel. There is space between the strips, and the strips are set on the surface of the flue gas duct plate to ensure the strength of the flue gas duct plate. There is space between the strips, which saves raw materials and reduces weight; The thickness of the flue gas channel plate can be reduced by arranging several strips on the top, and the thickness of the entire flue gas channel wall is the sum of the thickness of the flue gas channel plate and the plate strip. The section of the strip is rectangular, and a plurality of strips are arranged horizontally and parallelly on the flue gas duct plate.

Embodiment 2

[0025] Refer to attached image 3 , 4 , the present embodiment is a two-hole flue gas channel, and the plate strips 2 on the corresponding two flue gas channel plates 1 are provided with corresponding longitudinal through grooves 4, and are also provided with longitudinal inner hole partitions 5, longitudinally The inner hole partition is inserted into two corresponding longitudinal through grooves, which divides the space in the flue gas channel into two to form a two-hole flue gas channel. The section of the strip is rectangular, and a plurality of strips are arranged horizontally and parallelly on the flue gas duct plate.

Embodiment 3

[0027] Refer to attached Figure 5 , in this embodiment, a flue gas duct liner 3 is arranged outside the strip 2, and the strip 2 is clamped between the flue gas duct plate 1 and the flue gas duct lining 3; between the strip and the flue gas duct plate , The fixed connection between the strip and the flue liner.

Abstract

The invention relates to a combined flue, and belongs to the technical field of buildings. The technical scheme is that: more than two flue sheets are mutually matched and combined to form a complete flue; and the surface of each flue sheet (1) is provided with a plurality of belts (2), and spaces are reserved among the belts. The surface of the flue sheet is provided with the belts so as to ensure the strength of the flue sheet; and the spaces are reserved among the belts so as to save raw materials and reduce weight. The surface of the flue sheet is provided with the plurality of belts, so the thickness of the flue sheet can be reduced; and the thickness of the whole flue wall is the sum of the thicknesses of the flue sheet and the belts. The surface of the flue sheet is provided with the plurality of belts and the spaces are reserved among the belts, so the thickness of the flue sheet and the weight of the whole flue can be reduced, the raw materials can be saved, the weight and the cost can be reduced, and the production, transportation and installation of the flue sheet is facilitated.

Description

Technical field: [0001] The invention relates to a combined flue gas duct, which belongs to the technical field of building construction. Background technique: [0002] The flue gas duct is also called exhaust duct, exhaust duct, smoke exhaust duct, flue, etc. It is one of the important parts of the kitchen and bathroom in residential buildings. At present, the exhaust ducts of buildings commonly used by people are integral. Generally, templates are used and made of cement mixture, that is, single-section air ducts, cuboid and cylindrical. Due to the surface flatness and verticality of the air ducts, it is difficult to meet the quality requirements, and the exposed parts of the air ducts need to be plastered during installation. Handling: In the process of handling and installation, the single-section exhaust duct is not only inconvenient to transport, but also easy to be bumped and damaged, resulting in breakage and corner drop, resulting in waste. In order to solve this p...
