Problems solved by technology

The problem of this kind of combined flue gas channel is: because the flue gas channel panels are fixed together by glue and rivets, there is no structural hooking, locking, and corner seams at the joints, so the firmness Not good, the strength is not high, the structural integrity is poor, and the connection parts between the flue gas channel plates are easy to crack and separate, which affects the quality of the project

Embodiment 1

[0033] Embodiment one, with reference to the attached figure 1 , 2 , 3. The fire-proof combined flue gas channel adopts more than two flue gas channel plates 1, which are matched and combined with each other to form a complete flue gas channel. The sides of the two contacting flue gas channel plates are slopes that match each other. 2 shape, and there is a longitudinally penetrating groove on the slope 3, the two grooves contacting the flue gas channel plate are combined to form a columnar space, and the columnar space is filled with reinforcements, through which the flue gas channel plate connected together to form an integral structure. In this embodiment, the cross-sectional shape of the columnar space formed by the combination of two contacting flue gas channels is triangular; It is also triangular, directly inserted into the columnar space, and two adjacent flue gas duct panels are hooked together structurally and locked. In order to further improve the connection stre...

Embodiment 2

[0034] Embodiment two, referring to the attached Figure 4 , 5 6. In this embodiment, the cross-sectional shape of the columnar space formed by the combination of two contacting flue gas ducts is a combination of two geometric shapes, a combination of triangle and trapezoid, which further strengthens the integrity of the structure; the columnar space is filled with The reinforced body is a prefabricated reinforced cylinder 4, whose shape matches the columnar space, and is also a combination of triangle and trapezoid. It is directly inserted into the columnar space and connects the two adjacent flue gas duct panels structurally. , and lock it.

Embodiment 3

[0035] Embodiment three, with reference to the attached Figure 7 , in this embodiment, the four flue gas channel plates 1 are matched with each other to form a complete rectangular flue gas channel. There are longitudinal through grooves, and the grooves of two contacting flue gas duct plates are combined to form a columnar space, and cement mixture is poured into the columnar space as a reinforcement, and two adjacent flue gas duct plates are fixed on the Together, they become a whole; in order to improve the strength, the steel bar 7 is first set in the columnar space, and then the cement mixture is poured. Traditional methods such as bonding and rivet connection are also used between the flue gas duct plates to increase the strength.

Abstract

The invention relates to a fireproof combined gas flue which belongs to the technical field of buildings. The invention adopts the technical scheme that more than two gas flue plates are adopted, mutually matched and combined as well as assembled together to form the complete gas flue, longitudinal grooves are arranged at the mutually contacted parts of the two adjacent gas flue plates, and the length direction of the longitudinal groove is consistent with the cavity body direction of the gas flue; the grooves of the two adjacent gas flue plates are assembled together to form a columnar space, a reinforcing body is arranged in the columnar space, and the gas flue plates are hooked together by the reinforcing body to form an integrated structure. The invention has the advantages that the gas flue plates are structurally hooked through the reinforcing body to form into a whole and are locked, so that the gas flue plates are firmly connected and have high strength and good structural integration, the connected part between the gas flue plates can not crack or be separated, and the engineering quality is improved.

Description

Technical field: [0001] The invention relates to a fireproof 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 so...
