The utility model also adopts the structure matching design of the bulge and the groove, when the assembly is carried out, the embedding between the bulge and the groove is utilized, the connection hole is combined, the grouting can be inwards carried out, and the integral sealing effect can be further improved.
Description
Technical Field
The utility model relates to the technical field of flues, in particular to a high-strength forming flue.
Background
The smoke exhaust air flue is mainly used for collecting oil smoke generated in kitchen operation of each room in a residential building so as to be processed and discharged uniformly, and accords with the modern life concept of green and environmental protection. With the development of city construction, residential district construction is increasing day by day, so the demand of smoke exhaust air flue on the market is also increasing.
At present, two kinds of flues are mainly used, one is a prefabricated flue which is integrally formed by adopting cement prefabrication, the wall thickness of a cement prefabricated flue is generally 1.5cm, and the vertical bearing capacity and the flexible impact resistance of the cement prefabricated flue are poor; the other type is a flue formed by splicing fireproof plates, and the flue is unstable in connection, weak in structure, short in service life and poor in heat preservation effect and is in a phase of elimination at present.
The strength of the existing prefabricated flue is not high due to the limitation of the wall thickness of the existing prefabricated flue, so that the service life of the existing prefabricated flue is seriously limited, and in order to increase the strength and the sealing performance of the existing prefabricated flue, secondary plastering is usually needed, so that the construction cost of the existing prefabricated flue is increased.
