Description

A kind of high-altitude component hoisting construction method

technical field

The invention relates to a new type of high-altitude component hoisting construction method, more specifically, a kind of suggested and feasible component hoisting project used in high-rise building projects when vertical equipment cannot be used for component hoisting and installation. Construction method of lifting and installation in place.

Background technique

With the development of modern construction technology, there are more and more high-rise buildings, and there are more and more construction designs for hoisting high-altitude components, and the superiority of steel structure construction is becoming more and more important. Because the vertical transportation equipment used in the construction of the original structure, such as the tower crane, has been removed How to make the construction operation of steel components safer, more convenient and more efficient when installed in the sky has become an important part of the construction of the skylight.

Existing construction technology: It is necessary to use the vertical transportation equipment in the construction of the original structure, such as tower cranes. If it has been dismantled, the later construction cannot be carried out, because the construction project of the skylight is generally not too large. If the original vertical transportation equipment is used to ensure the steel structure construction of the skylight Equipment retention will add significant construction costs.

Contents of the invention

The present invention provides a new type of high-altitude component lifting construction method in order to avoid the shortcomings of the above-mentioned prior art, so as to facilitate component hoisting operations in high-altitude conditions, improve operational safety, reduce labor intensity, and effectively improve hoisting efficiency. The work efficiency is high, and the lifting equipment can be recycled.

The present invention solves technical problem and adopts following technical scheme:

A construction method for hoisting high-altitude components, comprising the following steps:

a. The triangular steel frame with the hoisting beam is fixedly connected with the steel frame of the movable chassis. A manual hoist is installed on the hoisting beam, and the components to be hoisted are fixed by the manual hoist cable, and the installation is carried out through the movement of the triangular steel frame and the manual hoist. , The components in place form the lifting equipment as Bagan crane;

b. Move the dry crane to one end of the component to be lifted, and then adjust the counterweight of the dry crane according to the weight of the component to be lifted to form a stable lifting system;

c. When lifting the components, fix the two ends of the components to be lifted on the manual hoist cables of two different cranes and keep the lifting points at the same height, and move the lifting components to the installation site by manually moving the cranes;

d. After the component is hoisted to the designated place, the lifting component is first connected with the installed component by welding or bolting, and the hook is dropped when the force of the temporary fixing point of the lifting component can meet the force of the component itself.

The movable chassis has rollers.

Compared with the prior art, the beneficial effects of the present invention are as follows:

1. Self-made lifting equipment, which can be used repeatedly, and is convenient for lifting and positioning of lifting components;

2. The construction operation method of the lifting equipment can be used at high altitudes where the original vertical transportation equipment or existing lifting equipment cannot be used. It is simple to manufacture and low in cost. The lifting range is enlarged by installing movable wheels to meet the construction needs.

The invention is simple and practical, does not need to retain the original vertical transport equipment, improves the safety of construction personnel, reduces the labor intensity of workers to a certain extent, effectively improves the efficiency of component hoisting, and increases the turnover times of hoisting equipment.

detailed description

A construction method for hoisting high-altitude components, comprising the following steps:

a. The triangular steel frame 1 with the hoisting beam is fixedly connected with the steel frame of the movable chassis 2. The movable chassis 2 has rollers, and a manual hoist 4 is installed on the hoisting beam 3, and the components to be hoisted are fixed by the manual hoist 4 steel cable 5. Through the movement of the triangle steel frame 1 and the lifting of the manual hoist 4 to install and place the components, the lifting equipment is formed as a Bagan crane;

b. Move the dry crane to the end of the component to be lifted, and then adjust the counterweight of the dry crane according to the weight of the component to be lifted to form a stable lifting system;

c. When lifting the components, fix the two ends of the components to be lifted on the manual hoist cables of two different cranes and keep the lifting points at the same height, and move the lifting components to the installation site by manually moving the cranes;

d. After the component is hoisted to the designated place, the lifting component is first connected with the installed component by welding or bolting, and the hook is dropped when the force of the temporary fixing point of the lifting component can meet the force of the component itself.

Claims (2)

1. a high-altitude component hoisting construction method, is characterized in that, include following steps:
