Tall and big space ultra-large air duct assembling device and construction method

Abstract

The invention provides a tall and big space ultra-large air duct assembling device and a construction method. The assembling device comprises a hoisting bracket and an assembling platform; the hoisting bracket comprises a transverse beam and two bottom beams, the two ends of the transverse beam are connected with the two ends of the two bottom beams through longitudinal beams, stiffening beams arearranged between the two bottom beams, a lifting device is arranged on the transverse beam and used for lifting air ducts, the two ends of the bottom beams are provided with traveling wheels, and profile projections of the longitudinal beams, the bottom beams and the stiffening beams form a triangle; the assembling platform is composed of standard joints of a box frame structure, and the standardjoints are used for allowing the air ducts to be placed; the hoisting bracket cooperates with the lifting device, and the inner space of a venue is utilized to the greatest extent; according to the length of the assembled air ducts, after the multiple standard joints are selected to be assembled, the air ducts are placed on the standard joints, the flexibility is high, the hoisting bracket has the air duct transferring function, and the multiple air ducts can be hoisted and installed at a time; and the high altitude construction time is shortened, the high altitude construction risk is reduced, the structure is simple, and manufacturing is easy and quick.

Description

technical field [0001] The invention belongs to the technical field of ventilation duct installation, and in particular relates to an assembly device and a construction method for a super-large air duct in a tall space. Background technique [0002] With the development of the national economy, there are more and more venues with tall spaces, and there are more and more super-large air ducts in the tall spaces. The overall size of the air ducts can reach 5 meters x 3 meters, and the installation height is about 20 meters. , with the implementation of the new anti-smoke exhaust duct specification, the weight of the anti-smoke exhaust duct will reach about 600kg per meter. Due to the large volume, heavy weight and weak strength of this kind of air duct, how to ensure the convenience of air duct assembly and the safety of hoisting is the difficulty of construction when assembling and hoisting on the ground. The purlins are all installed in place, there is no room for a crane. ...

Problems solved by technology

Due to the large volume, heavy weight, and weak strength of this kind of air duct, how to ensure the convenience of air duct assembly and the safety of hoisting is a difficult point in construction during ground assembly and hoisting. The purlins are all installed in place, there is no room for a crane. The conventional installation method of the air duct is to use a scissor lift car to lift the air duct to the installation position and then fix it. This method is not suitable for the installation of super large air ducts. The type lift car can only lift one section of air duct at a time, which is inefficient, long working hours, high cost and high risk
