Description

Parts splitting method and application suitable for intelligent construction of railway prefabricated beam steel frame

technical field

The invention belongs to the technical field of intelligent manufacturing of steel skeletons for railway prefabricated beams in civil engineering, and in particular relates to a method for disassembling parts, computer equipment and information data processing terminals suitable for intelligent building of steel skeletons for railway prefabricated beams.

Background technique

Prefabricated beams are widely used in my country, especially in railways. The construction of prefabricated beam reinforcement skeleton is the current control process of the beam yard, including reinforcement processing, transportation, laying and binding, etc., and multiple steel reinforcements are manually built into steel reinforcement skeletons. In the traditional manufacturing method of prefabricated beam steel skeleton, a single steel bar is mainly bent and processed, and after assembly, it is bound at the intersection to form a steel skeleton.

Rebar laying workload is large. For example, 32m simply supported box girder bars of high-speed railway need to be laid in total of 10,000 bars, totaling about 60t. Among them, bar laying is the most time-consuming in the whole steel bar frame manufacturing process. Reinforcing bar binding workload is large, and the simply supported box girder bars need to be bound at about 100,000 points, accounting for about 15% of the entire process of the reinforcement cage.

The overall efficiency of prefabricated beam steel skeleton construction is low. Generally, nearly a hundred people are required to work together, and one beam can be produced in one day; manual binding/welding, the laying accuracy of steel bars is not high, the positioning is not accurate, and the order of laying and binding steel bars will also be wrong. At the same time, there are missing bindings in binding and virtual welding in welding, which will have adverse effects on the quality of the bridge; the steel frame manufacturing workers are in a 30-meter * 15-meter area of the steel frame pedestal to carry out the binding and welding of steel bars. Welding, and there are gantry cranes over the area to transport steel bars, so there is a great safety hazard. Therefore, it is necessary to consider improving the construction technology of steel frame from the design, improve the automation and refinement of construction, closely link design and construction, and finally improve the automation level of steel frame construction.

Through the above analysis, the existing problems and defects in the prior art are: in the traditional manufacturing method of prefabricated beam steel skeleton, the steel bar laying workload is large, time-consuming, inefficient, the steel bar laying accuracy is not high, the positioning is inaccurate, the steel bar laying and The lashing sequence will be wrong; at the same time, the missing lashing phenomenon in lashing and the virtual welding phenomenon in welding will have a negative impact on the quality of the bridge, and there is a great potential safety hazard.

The difficulty of solving the above problems and defects is: the design and construction of structural parts has been a hot research topic in recent years. By splitting the steel frame into independent parts, the automatic processing of parts has been the focus of civil engineering structure research in recent years. Efficient disassembly of steel skeleton parts can provide a new idea for the intelligent construction of steel skeleton.

The significance of solving the above problems and defects is: by splitting the steel skeleton into steel parts that can realize automatic processing, optimizing from the design source provides a theoretical basis for the subsequent equipment processing.
