Accurate building component hoisting construction method

Abstract

The invention discloses an accurate building component hoisting construction method. The method comprises the steps that after being hoisted to an installation floor through a ground crane, a structural component is transferred to an installation position through a crane on the floor to be installed. Hydraulic transmission is adopted for installing components of the floor crane, the components can be accurately in place, and the defects that in the existing construction technology, when a ground crane adopts a sling to hoist the components, the components swing indefinitely and are difficult to accurately install in place are overcome.

Description

Technical Field

[0001] The invention relates to a hoisting construction method for assembled building components. The innovation of the method is that the swinging phenomenon during component hoisting in the existing process is eliminated, and the components can be installed accurately and stably. Background Art

[0002] In prefabricated building construction, components are installed using cranes parked on the ground. Because the crane's slings are flexible, the components are constantly oscillating due to the lifting motion and wind forces. This makes it difficult to precisely position the components, and can even cause collisions. In severe cases, this can impact the workers, leading to chipped components and even accidents. Summary of the Invention

[0003] In order to solve the above problems in hoisting construction, the present invention provides a hoisting method, which uses two cranes located on the ground and the floor to work together, which can accurately position the components and avoid accidents such as component collisions or even collisions with people.

[0004] The technical solution adopted by the present invention to solve its technical problems is: during the hoisting operation of the assembled components, a crane is added to the component installation floor. After the components are hoisted to the installation floor by the ground crane, the components are transferred to the floor crane. The floor crane directly holds the components with its lifting arm (or lifting platform), horizontally transports the components on the floor to the installation position, and uses hydraulic transmission to accurately install the components at the designed position.

[0005] The beneficial effect of this invention is that it changes the positioning process of hoisted components from swinging to smooth positioning, improving installation accuracy and eliminating the possibility of component collisions and even collisions with people caused by swinging. Furthermore, the floor crane can also perform horizontal transportation between floors, which not only reduces the lifting range requirements of the ground crane, but also eliminates the need for the crane to be moved during the lifting process, thereby improving lifting efficiency. BRIEF DESCRIPTION OF THE DRAWINGS The present invention will be further described below with reference to the accompanying drawings and examples. Figure 1 This is an example diagram of floor slab hoisting.
