What is the operation of drilling on steel structure engineering?

Steel structure engineering is widely used in daily life. In welding structure, it is inevitable that steel welding shrinkage and deformation will occur. Therefore, in the production process, grasp when the opening can greatly affect the accuracy of the overall material. So, how much do you know about the hole-making process in steel structure engineering processing? Let's take a look.

In the case of column structure and beam structure construction in steel structure engineering, the dimensional accuracy of holes in steel connection parts can directly affect the accuracy of steel structure engineering installation. Timing the opening is very important. The staff at one end of the component first drilling processing, to be assembled, welding and deformation correction completed, and then on the other end of the drilling processing. In the steel structure engineering processing of the member processing on the hole in advance, to be assembled, welding and deformation correction completed, and then marking confirmation of drilling processing.

Wait until the steel deformation correction, we need to finish the end of the steel, and then to finish the surface as a benchmark, marking, drilling. In marking, taking into account the welding shrinkage, deformation allowance, tolerance and so on, directly drilling. Mechanical drilling with electric drill and pneumatic drill, vertical drilling machine, radial drilling machine, truss radial drilling machine, multi-axis drilling machine, NC hole.

Sometimes steel needs to be perforated with gas. The easiest method we use is to install a simple accessory device on the gas cutting nozzle of the equipment, which can punch holes of φ30. Drill die and plate sleeve drill holes. This is a kind of steel structure engineering hole making method is not popular in China at present, the application of fixture fixed, drilling sleeve should be used carbon steel or alloy steel. The upper and lower planes of the drilling template shall be parallel, and the deviation shall not be more than 0.2mm. The center of the drilling sleeve shall be vertical to the plane of the drilling template, and the deviation shall not be more than 0.15mm. The allowable deviation of the overall drilling template production shall conform to relevant regulations.

Through the analysis of the content of the article, we can generally understand the steel structure engineering processing in the hole making process. All parts of the processing and production are very important, if you want to get good steel structure engineering processing quality, it is necessary to control its hole making process. I hope the introduction is helpful to you.
