Problems solved by technology
Large-scale fire-resistant air ducts are not only difficult to process, connect, and install, but also difficult to control the installation quality of bracket manufacturing and fire-proof board encapsulation, or the control is unstable, and require galvanized steel air ducts to be outsourced with fire-proof boards
The fireproof board is a fireproof board containing asbestos fiber. Asbestos board aging will release asbestos fiber, which is harmful to the human respiratory system.

Embodiment Construction
[0081] Such as Figure 1 to Figure 18 As shown, the modular assembly method of the low-noise non-asbestos calcium silicate board fireproof air duct of the present invention comprises the following steps:
[0082] Step 1. Determine the structure of the basic pipe joints: determine the structure of the basic pipe joints, the basic pipe joints include the air duct four-way pipe 8, the air duct three-way pipe 3, the air duct steering pipe 4, the air duct changing pipe 5, the straight air pipe Pipe segment 1, the air outlet pipe 9 is reserved on the straight air pipe segment 1;
[0083] The straight air pipe section 1 is a rectangular pipe type straight air pipe section, and the rectangular pipe type straight air pipe section includes a straight air pipe section first fireproof board 11-1 and a straight air pipe section arranged in parallel The second fireproof board 11-2 of the section, the third fireproof board 11-3 of the straight air pipe section and the fourth fireproof board...

The invention discloses a modular assembly method of a low-noise asbestos-free calcium silicate board fireproof air pipe. The modular assembly method comprises the steps that 1, a basic pipe joint structure is determined; 2, a topological structure of the low-noise asbestos-free calcium silicate board fireproof air pipe is determined; and 3, modular assembly is carried out on the low-noise asbestos-free calcium silicate board fireproof air pipe. The method is simple in step, the fireproof air pipe with any topological structure is formed by assembling an asbestos-free calcium silicate flat plate, a flange and a fireproof plate connecting piece, assembling is easy, fast and stable, the dead weight is low, an asbestos-free calcium silicate flat board has a certain thickness and cannot shake under the action of wind power, noise is low, an internal supporting piece, the flange and the fireproof plate connecting piece can be repeatedly used, a asbestos-free calcium silicate board is used for replacing an asbestos board under the condition that the strength is guaranteed, and therefore asbestos fibers can be prevented from being released when the asbestos plate is aged, and health and environmental protection are achieved.
Description
technical field [0001] The invention belongs to the technical field of fireproof air duct structure and assembly, and in particular relates to a modular assembly method for a fireproof air duct of a low-noise non-asbestos calcium silicate board. Background technique [0002] In building mechanical and electrical engineering, the fireproof board air duct is mainly used for the protection of the basement smoke exhaust system or exhaust and smoke exhaust system, air conditioning ventilation system and the air duct passing through the fire compartment. Especially for air ducts where the system air pressure is above medium pressure or has cleaning requirements. Generally, due to the large air volume and relatively large air duct size, processing and installation are also relatively difficult. Large-scale fire-resistant air ducts are not only particularly difficult to process, connect, and install, but also difficult to control the installation quality of bracket manufacturing an...
