Installing device and method for spiral air hoses in ultra high and large space truss

Abstract

The invention discloses an installing device and method for spiral air hoses in an ultra high and large space truss and relates to the technical field of ventilation and air conditioner engineering in order to solve the problems that when existing spiral air hoses in the ultra high and large space truss are installed, installing efficiency is low, the danger degree is high and air hose positioning and leveling are difficult. The installing device comprises a plurality of hanging type lifting platforms and a plurality of branch hanging frames, each hanging type lifting platform comprises a steel platform system and a hanging and lifting system, the hanging type lifting platforms are hung on purlines of the truss, and the branch hanging frames are installed on the truss. The construction method includes the steps that scaffolds are erected on the two sides of the truss, a header branch hanging frame is fixed to an upper chord frame of the truss, and the single-segment spiral air hoses are hoisted into the truss and spliced; second, an air hose header is hoisted to the designed elevation along with the truss as a whole and is installed; third, an electric hoist is fixed to the purlines of the truss, and an air hose main pipe, branch pipes and air ports are hoisted and installed through the electric hoist and the hanging type lifting platforms.

Description

technical field [0001] The invention relates to the technical field of ventilation and air conditioning engineering, in particular to a device and method for installing a spiral air duct in a super-high large-space truss. Background technique [0002] With the development of society and economy, my country will build more and more large-scale stadiums, hangars, large-scale exhibition venues, etc. These venues have the characteristics of large space, large span, and high headroom. The installation of such a large-diameter spiral air duct in a large space usually uses a winch or an electric hoist, and the installation height is usually not more than 20m. Scaffolding can be used to lay bamboo fences as an installation and operation platform, which has a long construction period and low efficiency. However, there are often the following difficulties in the installation of large-diameter double-layer spiral thermal insulation ducts with an installation height of about 40m and a d...

AI Technical Summary

Problems solved by technology

[0008] Aiming at the problems of low efficiency, high risk, and difficulty in positioning and leveling the air duct in the existing installation of the spiral thermal insulation air duct in the super-high and large space truss at high altitude, the purpose of the present invention is to provide a The device and method for installing the spiral thermal insulation air duct in the space truss use the suspended lifting platform as the operating platform for the construction personnel, and at the same time as the transportation platform for the pipe components such as air duct branches and air outlets, and as the transportation platform for other construction materials. The group suspended lifting platform also has the functions of vertical lifting, vertical and horizontal movement, block segmentation and connection as a whole according to needs, which can not only meet the efficient hoisting and installation of air duct components, but also save the construction period and construction cost
