Device and method for overall inverted construction of steel structure between multi-storey concrete bent frame columns

Abstract

The invention discloses an integrated inverted construction device and method for a steel structure between multilayer concrete bent frame columns and belongs to the technical field of building construction. Each layer of the concrete bent frame columns is provided with embedded parts. The embedded parts on the top-layer concrete bent frame columns are fixedly connected with top-layer steel structure pieces in a welded mode. A plurality of lifting devices are arranged on the op-layer steel structure pieces. The interior of each hanging plate is of a cuboid structure with one open end. The hanging plates are used for being clamped on the outer portions of the corresponding top-layer steel structure pieces. An opening of the lower end of each hanging plate is sealed through an anti-drop baffle. The two joints between each hanging plate and the corresponding anti-drop baffle are fixed through a plug pin and a bolt respectively. The lower end of each electric chain block is connected with a steel structure piece to be hoisted. All the lifting devices are electrically connected with a synchronous control cabinet through electric chain block power lines. According to the integrated inverted construction device and method, the inverted construction principle is utilized, construction is conducted from the top layer to the bottom layer by layer, the labor intensity of workers is lowered, the mounting space is saved, and the steel structure between the multilayer concrete bent frame columns can be mounted quickly, efficiently and safely.

[0002] With the progress of society, there are more and more large-scale petroleum, chemical, energy and environmental protection projects, and the number of steel structure design layers between concrete bent columns is increasing, and the height is getting higher and higher. The current manufacturing and installation methods of steel structures Including factory prefabricated on-site installation and on-site prefabricated on-site installation. The traditional steel structure installation between concrete bent columns is installed one by one with a single beam by crane. The construction efficiency is low and the safety risk is relatively high. The structural assembly is installed by crane. Although the work efficiency has been improved, the safety risk is increased. The installation progress will be greatly affected by the slight deviation in the size of the steel structure assembly. With the widespread application of large cranes, prefabricated installations are generally carried out by cranes. However, when the steel structure between the multi-layer concrete bent columns is installed by a crane, it is difficult to control the adjustment direction and position of the steel structure. It is extremely troublesome to connect and fix the multi-layer concrete bent columns, and the effect of precise operation cannot be achieved. Moreover, the cost is high, and the daily rental of a crane and the oil cost a lot of money. The most important thing is that when the steel structure between the multi-layer concrete bent columns is installed by a crane, there is a great safety risk. The rope and hook construction between the crane arm and the steel structure is prone to safety accidents, and the construction progress is slow. In this case, it is necessary to continuously innovate construction methods to reduce costs, so as to be safe, stable, high-quality and on schedule. In order to solve the construction work efficiency and reduce the safety risk of the installation work of the steel structure of the first floor, the installation direction of the steel structure between the concrete bent columns will adopt the overall lifting and inversion construction method in the future, which can not only improve the work efficiency and ensure the installation accuracy requirements, but also reduce the safety risk.
