Installation method of fireproof plate at curved surface position of air pipe

Abstract

The invention discloses an installation method of a fireproof plate at a curved surface position of an air pipe. The fireproof plate is usually installed at an elbow, a climbing position and a curved surface air pipe position in a broken-line-shaped mode, the method is poor in attractiveness, high in space occupancy, unfavorable for arrangement of multi-specialty comprehensive pipelines and capable of causing collision, and plates can be wasted. In order to overcome the defects, a method of breaking up the whole into parts is adopted for the whole curved surface position of an air pipe by utilizing a calculus principle, the fireproof plate is cut into a narrow strip shape, the section is polished into an oblique angle, the fireproof plate is tightly connected during splicing, the curved surface is broken up the whole into the parts and is divided into a plurality of straight line segments, and the straight line segments are used for fitting an arc; the purposes of attractive appearance, low space occupancy rate and plate saving are achieved.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a method for installing a fire prevention board at a position on a curved surface of an air duct. Background technique [0002] In super high-rise buildings or large commercial complex buildings, due to fire prevention requirements, it is necessary to wrap the smoke and exhaust ducts with fireproof boards of corresponding fire resistance grades to meet the requirements of fire resistance limit. However, if the conventional fireproof board construction process is used, not only Complicated, takes up a lot of space, high cost, and poor aesthetics, and the traditional fireproof board is often installed in a zigzag shape at the elbow, elevation, and curved air duct. This method not only has poor aesthetics, but also has a high space occupation rate. , it is unfavorable for the arrangement of multi-specialty integrated pipelines, which will cause collision problems and waste b...

[0002] In super high-rise buildings or large commercial complex buildings, due to fire prevention requirements, it is necessary to wrap the smoke and exhaust ducts with fireproof boards of corresponding fire resistance grades to meet the requirements of fire resistance limit. However, if the conventional fireproof board construction process is used, not only Complicated, takes up a lot of space, high cost, and poor aesthetics, and the traditional fireproof board is often installed in a zigzag shape at the elbow, elevation, and curved air duct. This method not only has poor aesthetics, but also has a high space occupation rate. , it is unfavorable for the arrangement of multi-specialty integrated pipelines, which will cause collision problems and cause waste of boards. In order to overcome these shortcomings, a method of installing fireproof boards at the position of the curved surface of the air duct is proposed
