Description

Steel framework hoisting process, hoisting equipment and auxiliary device

Technical Field

The application relates to the field of building construction, in particular to a steel framework hoisting process, hoisting equipment and an auxiliary device.

Background

The steel framework is also called a steel structure framework, is a structure commonly used in the building field, and when building personnel are constructed, the steel framework is often required to be hoisted in a building structure from the ground, and in the process, the steel framework is required to be lifted to a certain height by bypassing some barriers of construction sites such as external structures of the building.

In the related art, a constructor usually lifts a steel frame directly using a crane, moves to a designated height and position, and then lifts the steel frame to an installation position by the crane.

In view of the above related art, the inventor believes that some steel frames are too heavy and long, and if the whole steel frame is hoisted, a large-tonnage crane is required to be purchased or called for, and some steel frames with long lengths are not convenient to directly hoist integrally.

Disclosure of Invention

In order to facilitate hoisting of a steel framework, the application provides a steel framework hoisting process, hoisting equipment and an auxiliary device.

In a first aspect, the application provides a steel frame hoisting process, which adopts the following technical scheme:

a steel frame hoisting process comprises the following steps:

s1, cutting a steel frame: cutting the steel framework into a plurality of sections of partial frameworks;

s2, assembling a steel framework:

s21, lifting a section of local framework, and installing the local framework on lifting equipment, wherein the lifting equipment is positioned in a region where the steel framework is to be installed;

s22, lifting the rest partial frameworks, and splicing and connecting the rest partial frameworks with the partial frameworks on the lifting equipment until all the partial frameworks are spliced into a complete steel framework;

S3, hoisting a steel frame: and adjusting the position of the steel framework, and hoisting the steel framework at the installation position.

In S22, two methods are included:

in the first mode, in the rest partial frameworks, more than two sections of partial frameworks are hoisted at the same time, then the hoisted partial frameworks are moved to hoisting equipment, and the partial frameworks on the hoisting equipment and a plurality of sections of newly hoisted partial frameworks are spliced and connected at the same time;

in the second mode, the partial frameworks of the other sections are lifted one by one, then the single partial framework lifted each time is moved to the lifting equipment, and the newly lifted single partial framework is spliced and connected with the partial frameworks on the lifting equipment.

Through adopting above-mentioned technical scheme, when the steel framework that needs to hoist is long and heavy, can cut the steel framework, divide into the local framework of multistage length weak point, install lifting device on the structural layer of waiting to install the steel framework, then hoist one of them section local framework, according to the height and the position of structural layer, the lifting is with removing the local framework that hoist, because single local framework weight is lighter and the length is shorter, use the crane commonly used of small-tonnage, can hoist single local framework, constructor need not additionally purchase or call the crane of bigger tonnage any more, save economic cost, also be convenient for the mobilization and the selection of on-the-spot construction equipment, the construction operation of staff provides convenience.

After the first local framework is hoisted and moved to the installation area, the local framework is connected to hoisting equipment, then other local frameworks are hoisted to be connected with the local frameworks on the hoisting equipment, and the hoisting and the movement of the rest multi-section local frameworks are completed through the process of the application, and the hoisting and the movement can be realized by using a conventional crane on the construction area; in addition, the construction operation is carried out on the single-section local framework, so that the lifting and moving processes are more stable, the possibility of unbalanced inclination of the steel framework in the lifting and hanging process is reduced, and the potential safety hazard is reduced; meanwhile, the workers move the longer steel framework to the installation area in a segmented mode through cutting and then assembling, so that the possibility that the overlong steel framework collides with the surrounding building structure during direct hoisting is reduced.

When all the partial frameworks are assembled in the installation area, the assembled integral steel framework is positioned on the hoisting equipment, the hoisting equipment is positioned on a structural layer of the steel framework to be installed, the hoisting equipment can directly support the steel framework on the structural layer, and at the moment, the stress point of the pressure born by the hoisting equipment is positioned near the gravity center of the hoisting equipment; if the crane is used, the crane can not directly open the upper structural layer basically, the crane positioned far away needs to extend the suspension arm in the inclined direction, the steel framework is conveyed to a position which is far away and higher than the installation position through the suspension arm, the gravity center position of the crane is far away from the pressure point of the steel framework, and if the crane is insufficient in weight, the risk of side turning can occur; therefore, compared with the process of directly lifting by a crane, the lifting device adopted by the process disclosed by the application is more stable in operation in the lifting process.

Because the construction site condition is complex, and the structural layer of the steel framework to be installed can be positioned at a high-rise structure, the hoisting condition of the steel framework can not be observed through eyes; when the steel frame is positioned on the hoisting equipment, the hoisting equipment and constructors are positioned on the same structural layer, and the constructors can adjust the position and the height of the steel frame by controlling the hoisting equipment to hoist the assembled steel frame; because the station of constructors can directly observe the whole hoisting process by naked eyes, the hoisting can be more accurately carried out, compared with the hoisting from the ground upwards directly, the possibility of position deviation of the steel framework in the hoisting process is reduced, the process of the application does not need repeated reworking, and the construction efficiency is improved.

In the process, a constructor can select which construction mode to use according to site construction conditions, and when a plurality of cranes can bear hoisting operation at the same time on a construction site, a first mode is used for installing a plurality of sections of local frameworks at the same time, so that the construction time is shortened; when the field device does not allow the multi-section local framework to be assembled synchronously, the second mode is used for lifting, moving and assembling one by one, more cranes and staff can be saved by using the mode, the saved equipment and staff can be used for construction elsewhere, more equipment and staff can be allocated during construction on a construction site, different schemes are provided for different construction conditions, and more constructors can select.

In conclusion, the process is convenient for constructors to hoist the steel framework.
