Abstract

The invention relates to an integrated fireproof exhaust pipeline for kitchen and bathroom. The exhaust pipeline has an integrated pipeline structure of which the section is square and which is manufactured on a special mold, wherein the length of the pipeline is 2,500 to 3,500mm; the side length A or side width B of the square section of the pipeline is 250 to 800mm; the wall thickness of the pipeline is 5 to 15mm; and four interior angles of the cross section of the pipeline are arc-shaped, and 45-degree chamfers or right angles. The exhaust pipeline is made of a magnesite material or low-alkalinity cement, vitrified micro bubbles or ceramsite sand, short fiber, a mesh fabric or steel wire mesh, a flame retardant, a modifier, fly ash, waste paper pulp and sawdust. A method for manufacturing the exhaust pipeline comprises the following steps of: laying the mesh fabric or steel wire mesh between an internal mold and an external mold of the special mold which is horizontally arranged on a vibration machine; uniformly stirring ingredients and injecting the mixture into a mold cavity under vibrating to ensure that the ingredients are uniformly distributed and filled in a gap; and drying the exhaust pipeline in the mold, molding and demoulding to obtain the integrated fireproof exhaust pipeline for the kitchen and bathroom.

Description

technical field [0001] The invention relates to an integrated kitchen and bathroom fireproof exhaust duct and a preparation method thereof, belonging to the technical field of construction. Background technique [0002] Existing residential kitchen and bathroom flue gas discharge pipes are generally prefabricated with concrete, and the wall thickness of the concrete pipe is generally 1cm. Due to the high temperature of the exhaust gas in the kitchen, this kind of pipe often cracks during use. It will cause the collapse of the pipeline, block the pipeline of the residents on the ground floor, and do not meet the existing national standards, affecting the life and safety of residents' houses. [0003] Publication No. CN201531107U discloses a combined internal mode kitchen and bathroom fireproof exhaust duct. The patent is based on the internal mold, the outer frame long board is pasted outside the inner mold, and the triangle is pasted at the corner of the two outer frame long...
