Abstract
The present invention relates to a truss structure member having an assembly hole with a tapered extension portion and a structure using same, and provides a truss structure member and a structure, the truss structure member being capable of enabling a truss structure member and a truss structure member or a truss structure member and a connection member to be firmly fastened to each other without clearance even when a gap is generated between a fastening tool and the assembly hole.
Claims7
A truss structure member having an assembly hole with a tapered extension portion, the truss structure member comprising:
- a flange portion (111);
- an assembly hole (112);
- and
- a tapered extension portion (113),
- wherein the truss structure members are formed in bar shapes so as to be coupled to each other to form a truss structure having a predetermined form, the flange portion (111) having a flat structure is formed in at least one of opposite ends of the truss structure member, the assembly hole (112) through which a fastening tool (140) passes is formed in the flange portion (111), and the tapered extension portion (113) is formed around the assembly hole (112),
- wherein the tapered extension portion (113) has a ring structure extending around the assembly hole (112), and has a sectional surface shaped to protrude with an inclination from vicinity of the assembly hole (112) toward an inside of the assembly hole (112) so as to be an overall conical shape, in which an inclined outer surface (113a) of the tapered extension portion (113) comes in close contact with an inclined inner surface (113b) of a tapered extension portion (113) formed on another truss structure member (110), so that the truss structure members (110) are coupled to each other in a structure without clearance while the tapered extension portions (113) of the truss structure members (110) coupled to each other are overlapped with each other to form a truss structure.
3 more elements
A structure comprising:
- a plurality of truss structure members,
- wherein each of the plurality of truss structure members comprises:
- a flange portion (111);
- an assembly hole (112);
- and
- a tapered extension portion (113),
- wherein the truss structure members are formed in bar shapes so as to be coupled to each other to form a truss structure having a predetermined form, the flange portion (111) having a flat structure is formed in at least one of opposite ends of the truss structure member, the assembly hole (112) through which a fastening tool (140) passes is formed in the flange portion (111), and the tapered extension portion (113) is formed around the assembly hole (112),
- wherein the tapered extension portion (113) has a ring structure extending around the assembly hole (112), and has a sectional surface shaped to protrude with an inclination from vicinity of the assembly hole (112) toward an inside of the assembly hole (112) so as to be an overall conical shape, in which an inclined outer surface (113a) of the tapered extension portion (113) comes in close contact with an inclined inner surface (113b) of a tapered extension portion (113) formed on another truss structure member (110), so that the truss structure members (110) are coupled to each other in a structure without clearance while the tapered extension portions (113) of the truss structure members (110) coupled to each other are overlapped with each other to form a truss structure,
- wherein the plurality of truss structure members are coupled to each other to form a predetermined shape.
