Description

Composite joint structure of steel pipe and H-beam The present invention relates to a composite joint structure using a steel pipe and an H-shaped steel, and more specifically, to a composite joint structure of a steel pipe and an H-shaped steel that improves upon the problems that may occur in existing field welding or pin joining methods through a structure in which the steel pipe and the H-shaped steel are composited. In structures such as buildings, bridges, and tunnels, the connection between steel beams or between steel beams and steel columns is considered a critical matter by those skilled in the art to ensure structural stability and durability; as such, welding and pin joint methods are representative technologies used for this structural connection. Here, welding is the most widely used method for joining steel pipes, offering high bond strength and a semi-permanent connection; however, it relies on skilled personnel for on-site work, and structural defects may occur depending on the welding quality. Additionally, welding is time-consuming, and construction can be delayed due to environmental factors such as weather. Thermal deformation at the welded joints is also a risk factor that can lead to structural deformation. Furthermore, while the pin joint method has the advantage of avoiding field welding, it has the disadvantage of lower structural strength and inability to evenly distribute loads due to the fact that it allows for pin rotation. Particularly in the case of large structures, the pin joint method has limitations in supporting high loads and faces the problem of being difficult to apply to members of various specifications. For these reasons, the pin joint method is used restrictively in structures requiring high strength. Since the current joining method involves connecting steel pipes of a predetermined length during the design phase, errors occur during the on-site construction phase. Consequently, on-site workers overcome these errors using unsafe methods, such as forcibly fitting heavy steel pipes when the lengths do not match or forcibly filling the gaps between steel pipes to make up for the short length. At this time, by introducing and connecting H-beams, or H-shaped steel, between the steel pipes, it is possible to efficiently support and transmit loads according to the unique structure of the H-shaped steel, which consists of a flange and a web, while also enabling strong fastening of connecting members in a planar configuration. In addition, due to the structure that allows for strong fastening, the connection points can be connected at a certain distance apart, enabling on-site construction without welding. Furthermore, by allowing a slight margin in the length of the steel pipe during the design phase, adverse effects caused by errors in the length of the steel pipe can be eliminated. This is because it is more efficient to manufacture new connecting members or change the specifications rather than manufacturing new steel pipes. Therefore, there is a growing need for composite joint structures of steel pipes and H-shaped steel that can enhance on-site construction ease and assembly safety, and reduce construction time.
