Technical Field
The invention relates to the technical field of vertical air ducts and air ducts, in particular to a multi-section air duct structure in a narrow vertical air duct.
Background
Buildings such as high-rise houses and the like are required to introduce and exhaust smoke, and an air shaft is often arranged to intensively deal with the indoor smoke emission problem. Generally, the air shaft is used as an air duct, and a corresponding air pipe is arranged in the air duct to remove smoke. Because the height of the building is larger, the air pipes are generally manufactured into a plurality of sections of air pipes with smaller lengths, and the air pipes are spliced and assembled to form a complete air duct during construction.
The existing air pipes are generally made of section steel, the main body is covered on the surface of the main body through color steel, iron sheets and the like to form a complete air pipe structure, and the multi-section air pipes are fastened and connected through bolts to complete splicing. Because the distance between the air pipe and the wall of the air shaft is only 50-100 mm when the air pipe is installed, the installation of bolts in narrow gaps is very difficult in the splicing process, and the efficiency is low; and generally need set up a plurality of bolts in the edge of tuber pipe interface and can realize connecting, need consume very big manpower and material resources. Even so, after the installation of tuber pipe is accomplished, because the clearance is narrow and small, the bolt is numerous, if need carry out maintenance very difficult.
Therefore, the structure of the lining air pipe arranged in the existing air duct still has a space needing to be improved, and mainly solves the problems of inconvenient construction and difficult maintenance in a narrow space and low efficiency. The air pipe structure should be optimized and improved or be suitable for a more applicable structure, so a more reasonable technical scheme needs to be provided, and the defects in the prior art are overcome.
