The present invention relates to a hinge point portion of a steel pipe truss structure, a steel pipe truss structure manufactured using the same, and a construction method thereof. More specifically, the present invention relates to a hinge point portion between a slant member connected to an upper and a lower portion of a truss structure using a steel pipe, and a steel pipe truss structure A hinge point portion, a steel pipe truss structure manufactured using the same, and a construction method thereof.

As a result, it can be seen that the pointed portion of the truss structure can be formed by a hinge structure. However, it can be seen that most of the truss structures are formed by welding or sandwiching the connecting plate and the gusset plate formed on the end surface of the inclined material. When a truss structure is fabricated with such a structure, assembly work of the upper and lower beams becomes complicated, and therefore, the workability of the truss structure is inevitably lowered due to on-site assembly.
Accordingly, it is possible to form a hinge structure, which is a connecting portion between the current upper and lower ends of the steel pipe truss structure and the slope member, by simplifying the assembling work of the slant member and the upper and lower members. The present invention provides a hinge point portion of a steel pipe truss structure and a steel pipe truss structure manufactured using the same.
In order to solve the above problems,
Preferably, the arc-shaped connecting plate is integrally formed on the upper surface of the lower surface of the two-gusset connecting plates inserted into the slot groove formed in the inclined steel pipe so as to extend in the longitudinal direction so as to cover the upper surfaces of the present-side steel pipe and the lower steel pipe. And a rear reinforcement plate in the form of a vertical plate formed in the back surface of the arc-shaped connection plate in the direction of extension of the arc-shaped connection plate.
Also,
Two phase steel pipes are separated from each other and connected to each other by using upper horizontal bracing. Two bottom steel pipes are separated from each other and connected to each other by using a horizontal horizontal bracing to form a flat member; And a slant member connected between the upper and lower current steel pipes and the lower steel pipe upper and lower by the hinge point gap portion (A), respectively.
Also preferably,
(a) Two horizontal pipes are separated from each other, and upper horizontal bracing is used to connect them to each other. The upper horizontal pipe and the two horizontal pipes are separated from each other by a horizontal horizontal bracing A slant member including a hinge point portion (A) connected between a bottom current generated by a flat member and a top and bottom current steel pipe and a bottom steel pipe connected to each other;
(b) bringing the rear reinforcing plate of the hinge point dividing point portion (A) into the slot connecting groove formed on the upper surface of the lower current portion in the longitudinal direction of the downstream steel pipe, Inserting the arc-shaped connecting plate into the formed slot connecting groove and fixing the arc-shaped connecting plate to the surface from the outside of the presenting steel pipe and the downstream steel pipe; (c) inserting the rear reinforcing plate of the hinge point dividing point portion (A) into the slot connecting groove formed in the longitudinally extending bottom surface on the upper surface of the upper current surface of the inclined material fixed at the lower end, To the surface of the steel pipe; And a step (d) of mounting a steel pipe truss structure fabricated by including the hinge point portion (A) on the bridge substructure, Thereby providing a method of constructing a steel pipe truss structure manufactured by using a point portion.
According to the present invention, it is possible to manufacture the steel pipe truss structure more quickly and economically by separately manufacturing the upper, lower, and lower sloping parts of the steel pipe truss structure and assembling by simple welding of the collar portions at the site.
In addition, a stiffener for supporting the steel pipe truss structure can be formed by forming a stiffener at the bottom end of the steel pipe truss structure so that it can be easily mounted on the insert plate of the permanent bridge support.
