Description

Shape steels used in construction and an apparatus therefor}

The present invention relates to an apparatus for manufacturing lightweight steel, which is used to support various equipment and its accessories during building and construction work.

Generally, the 'steel', 'H' steel, and 'I' steel are used to support various facilities and their accessories during construction and construction.

Most of these sections are supported by larger steel frames or concrete structures, and are used as posts and skeletons or frames supporting various pipes forming pipe lines, various panels attached to ceilings and walls, and ducts.

In addition, since the steel, mechanical, physical, and chemical properties are different depending on the shape and shape of the steel frame is selected according to the load and support location of the supporting equipment and conditions in the workplace.

By the way, since 'A', 'H' and 'I' steels, which have been used so far, are manufactured after being manufactured as a single unit in a manufacturing plant, they cannot be changed in shape, and it is difficult to select a suitable one. There was a downside.

In other words, the conventional section steel is made of integrally shaped section steel having a cross-section of 'A' type, 'H' type, and 'I' type in a manufacturing plant such as a steel mill, so it is quite suitable to select this in the work site for various facilities. It was limited.

In addition, this section steel is a single piece of internal and external steel, material loss is heavy, heavy, difficult to accurately fix the equipment in the desired position, localized changes due to welding, etc. It was often caused.

For example, in the field of mechanical equipment, welding, cutting, surface treatment, etc. are required when preheating a machine room, a joint tool, a plurality of pipes, or using a rack of a warehouse. Due to the heat generated, the material of the section steel is locally changed, and the strength is lowered.

Therefore, in the case of the fluid transfer pipe, the vibration caused by the speed of the fluid cannot be absorbed properly, and this vibration is adversely transmitted to the structure of the building, and during construction, many processes such as welding, cutting, and surface treatment are necessary. Manpower inputs such as welders, cutting workers, iron workers, auxiliary workers, and painters cause excessive labor costs, and additional costs such as increased construction costs due to material loss and indirect costs due to air delays weaken competitiveness. There was a problem.

The present invention has been devised to solve these problems, and the technical problem is to form a profile steel for use in building and construction as a lightweight profile, which is purely assembled, easy to manufacture, material saving and insulation and It is to provide an apparatus for manufacturing a section steel with excellent buffering effect.
