Device for hoisting prefabricated reinforced concrete column on site and walking technology thereof

Abstract

The invention relates to the field of building operations, in particular to a device for hoisting prefabricated reinforced concrete column on site and a walking technology thereof. The purpose of the invention lies in providing a simple yet effect walking technology for hoisting prefabricated reinforced concrete column on site and the device for realizing the technology; the design is simple and the operation is effective. To achieve the purpose, the invention provides the following technical proposal: the device of the invention is composed of a wheeled supporting plate, steel sheets and braking angle iron and has the following characteristics: the supporting plate is a right-angle structure, the top of the right angle is provided with deflectable rolling-over wheels, the two ends of the supporting plate far away from the top of the right angle are respectively provided with deflectable wheels, rotary connecting rods are arranged on a deflectable wheel seat. With the device of the invention adopted, mechanical efficiency can be effectively improved, construction productivity can also be enhanced, thus accelerating construction progress and enjoying extremely noticeable economic benefits and comprehensive benefits.

Description

Technical field: [0001] The invention relates to the field of building construction, in particular to a device for hoisting a prefabricated reinforced concrete column on site and a walking technology. technical background: [0002] At present, in my country's industrial plants, especially in heavy industrial plants, a large number of prefabricated reinforced concrete columns are used. According to the regulations of the existing building construction manual, the existing technical solution is to set pallets and rollers at the foot of the columns, and lay taxiways. At that time, the practices of various construction units were not uniform. Generally speaking, the pallets were made of steel plates, and the rollers were made of logs or steel pipes. It is very irregular, and a set of repeated facilities needs to be made for each cup foundation.

Problems solved by technology

[0002] At present, in my country's industrial plants, especially in heavy industrial plants, a large number of prefabricated reinforced concrete columns are used. According to the regulations of the existing building construction manual, the existing technical solution is to set pallets and rollers at the foot of the columns, and lay taxiways. At that time, the practices of various construction units were not uniform. Generally speaking, the pallets were made of steel plates, and the rollers were made of logs or steel pipes. It is very irregular, and a set of repeated facilities needs to be made for each cup foundation. The working method is very primitive, which not only wastes manpower and materials, but also has high work intensity and low efficiency. The sliding speed of the prefabricated columns is slow, which greatly increases the lifting equipment. Occupancy time, increase the cost of using a lot of hoisting equipment

[0003] At the same time, in the lifting stage of the installation process of these prefabricated columns, according to the self-weight of the prefabricated columns, the usual hoisting methods are single-machine hoisting (rotation method or sliding method) or double-machine hoisting (sliding method or delivery method). However, these general Both methods and methods have some disadvantages: the rotation method is not suitable for the situation where the prefabricated columns are stacked far away from the foundation of the cup; , the friction between the prefabricated column and the taxiway is large, which is equivalent to increasing the lifting capacity of the hoisting, and the walking speed is slow; the sliding method or the delivery method of the double-machine hoisting not only has the above-mentioned shortcomings, but also requires the two cranes to cooperate tacitly, otherwise, it is easy It will lead to the weightlessness of a single crane and overload the other one; during the lifting and righting stage, the column feet are prone to slip and generate dynamic loads, which will cause the crane to shake or even overload, and may even be dangerous
