Air relay type hoisting method of roofing colored plate of food refrigeration house

Abstract

The invention relates to an air relay type hoisting method of a roofing colored plate of a food refrigeration house. The air relay type hoisting method comprises the steps that 1) a scaffolding platform is built on one side of the food refrigeration house; 2) steel wire rope guide rails are arranged; 3) a hoisting and swinging device consists of a winch, a hoisting steel pipe, a hoisting steel wire rope and a bracket; 4) the roofing colored plate is entirely hoisted onto the bracket, the bottom of the roofing colored plate is supported by a supporting plate, the upper part of the roofing colored plate abuts against the hoisting steel wire rope, after the roofing colored plate is placed stably the roofing colored plate and the bracket are bound firmly, then the winch is started, hoisting force is applied through the hoisting steel pipe uniformly, and the roofing colored plate is entirely and steadily moved upwards till arriving at the scaffolding platform; and 5) through manual assistance, the roofing colored plate is transversely moved along the second section of the steel wire rope guide rail, and the step 4) is repeated. The air hoisting problem of the overlong roofing colored plate is solved, the roofing colored plate is free from damage in the hoisting process, and the air relay type hoisting method is convenient to implement, high in efficiency and good in economy and has popularization value.

Description

technical field [0001] The invention relates to the field of construction technology in the construction industry, in particular to an aerial relay hoisting method for colored panels on the roof of a food cold storage. Background technique [0002] Food cold storage is a building used for food freezing and cold storage. It uses artificial refrigeration to keep a certain low temperature in the storage. In order to ensure the good appearance and architectural effect and thermal insulation performance of the cold storage, the roof color board needs to be installed with the whole board. [0003] Most of the roof color panels are pressed and formed by the on-site press machine. When the length of the veneer is too long (more than 40m), there is no difficulty in the installation of the roof color panels, but the key technical problem that needs to be solved is how to smoothly install the super long roof panels When transported to the roof, the normal hoisting is to use a crane to...

Problems solved by technology

[0003] Most of the roof color panels are pressed and formed by the on-site press machine. When the length of the veneer is too long (more than 40m), there is no difficulty in the installation of the roof color panels, but the key technical problem that needs to be solved is how to smoothly install the super long roof panels When transported to the roof, the normal hoisting is to use a crane to lift directly; but for super long roof color panels, the normal hoisting method is not feasible at all, at least 2 cranes are needed to cooperate with lifting; even so, because the roof color panels are generally only a few millimeters Thickness, it is easy to produce deflection during the hoisting process, thus damaging the plate body
