Mounting method of metal air pipe with super-large cross section in vertical shaft

Abstract

The invention provides a mounting method of a metal air pipe with a super-large cross section in a vertical shaft, relates to the technical field about the mounting method of the metal air pipe in thevertical shaft and solves the technical problem that a mounting method cannot be applied to mounting of the metal air pipe with the super-large cross section in the prior art. The mounting method atleast comprises following steps: prefabricated metal air pipe standard sections are transferred into the vertical shaft from the top of the vertical shaft in sequence with a forward erection method; every two adjacent metal air pipe standard sections are subjected to built-in reinforcement treatment; a fixing bracket combination for fixing the metal air pipe standard sections and the inner wall ofthe vertical shaft is fixed in advance on the inner wall of the vertical shaft and the metal air pipe standard sections, and the metal air pipe standard sections and the inner wall of the vertical shaft are fixedly connected through the fixing bracket combination. With the adoption of the mounting method, the problem about mounting of the metal air pipe with the super-large cross section in the vertical shaft is effectively solved, and stability and firmness of the mounted metal air pipe with the super-large cross section in the vertical shaft can be guaranteed. The construction is simple andconvenient.

Description

technical field [0001] The invention relates to the technical field of installation methods for metal air ducts in shafts, in particular to an installation method for super-large-section metal air ducts in shafts. Background technique [0002] Metal air ducts include steel plate air ducts, stainless steel plate air ducts, aluminum plate air ducts and plastic composite steel plate air ducts. Air duct refers to brick and concrete air duct. At present, the air ducts used in the installation of air conditioning systems are generally fixedly connected outside the air ducts through the air duct flanges. Install the metal air duct into the air duct under the condition of no sundries. However, with the acceleration of the pace of urban modernization, the economic value of buildings has increased rapidly, leading to a rapid expansion of the optimization requirements for the available space areas in buildings under the premise of satisfying the functions of various systems.
