2. Description of the Related Art Beams and columns of the above-mentioned pedestrian deck and the like are generally made of H-shaped steel, I-shaped steel, square steel pipe, steel pipe or other iron-based materials as structural materials, and aluminum-based ones.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION Longitudinal caulking portions are provided at both ends of an upper and lower member having a predetermined width, which is flexible and can be plastically worked, such as an aluminum alloy profile, and positions of upper and lower ends of left and right side plate members. The deformed structural member can be formed by engaging the upper and lower ends of the left and right side plate members in a form to follow the change, and intermittently caulking at a predetermined interval to fix. That is, unlike a conventional structural member that linearly extends in the longitudinal direction with the same cross section, the cross-sectional shape is rectangular, but at least one of the upper end and the lower end is linear or curved in side view. By continuously changing the height, and by further changing the vertical height dimension interval, that is, the vertical width dimension,
It is possible to obtain a deformed structural material in which the shape of the side surface is changed.

This deformed structural material has a large bending rigidity because it is integrally formed in a rectangular shape with the vertical member and the horizontal member.
Depending on the bending moment, the vertical width can be changed to obtain the required bending rigidity, and the vertical height, that is, the beam width, increases from the center to both ends. Beam material, arch-shaped beam material in which the beam width increases from the central part toward both ends to form an arched side surface shape, arch-shaped beam material in which both the upper and lower ends are arched and the beam width does not change between the central part and both ends, Alternatively, it can be used as a cantilever type beam material in which the beam strain becomes smaller from one end side to the other end side, or in addition to a deformed structural material such as a column material having an upper part formed in a curved portion, the design of a building or a structure. Can also be diversified.

Then, the upper and lower members are preliminarily extruded into a bending process after being extruded or directly extruded in a bent state so as to be stretched at any angle or curvature in either the left or right direction in a top view. The upper and lower ends of the left and right side plate members are successively engaged with the caulking portions provided at both ends of the upper and lower members, and the caulking process is performed to fix the members to form a deformed structural material. Further, by changing the height or the vertical width dimension of the upper and lower ends of the left and right side surface plate members in a straight line or curved line, it is possible to obtain a deformed structural member having a changed shape in a side view.

According to the deformed structural material which is bent and changed in an arbitrary direction in the top view, the deformed shape such as the corner portion of the structural material, the corner portion of the balustrade, the frame corner portion of the transfer facility, the corner portion of the balcony handrail, etc. Can handle various requests. Further, by previously bending the upper and lower members individually at an arbitrary angle or curvature,
It is easier to prevent wrinkles from occurring because the entire surface of the bent material can be held during bending, as compared to bending the hollow structural material that is assembled after forming the upper and lower members in a straight line using a core. Therefore, since the left and right side plate members are connected after bending, the plate thickness of the left and right side plate members is not affected. Also,
Since the processing mold is compact, it is inexpensive, and further,
Since the bending material has a small section modulus, there is an advantage that it can be processed with a small processing force.

The upper and lower members having continuous caulking portions can be easily manufactured from a metal material obtained by extrusion-molding an aluminum alloy material or rolling-molding a plate-shaped material such as an aluminum alloy material or an iron plate by roll forming. The left and right side plate materials can also be easily manufactured by rolling or molding metal materials such as aluminum alloys or extrusion molding of aluminum alloy materials, and fixing the upper and lower members and the left and right side plate materials by intermittent caulking is a relatively simple facility. Can be done easily and efficiently. By forming the caulking portion of the upper and lower members into a thin portion and a caulking receiving piece formed into a thick portion facing each other having a receiving groove in the caulking piece,
By crimping from one side with a punch or the like caulking blade, caulking into the receiving grooves of the left and right side plate materials can be performed more easily and reliably.

By positioning the caulking portion in a vertically protruding state outside the hollow space formed by the upper and lower members and the left and right side plate members, the constitution of the caulking means is simplified, and this structural material is also suitable for a duct or the like which uses the internal space. Available for Also,
The structure in which the caulking portion is positioned outside the hollow space in a non-protruding state inside has a good finished appearance of this structural material, and since there is no protruding portion, convenience in mounting can be improved.

By forming the caulking piece on the outside and caulking it from the outside with a caulking blade such as a punch, the caulking can be performed relatively easily, the stability after the caulking is large, and the caulking piece is Those formed on the inner side and pressed by the caulking blade from the inner side have good appearance and finish. Furthermore, by using corrugated plates as the left and right side plate members, it is possible to further improve the strength including the bending rigidity of the deformed structural member. The shape of the upper and lower members made of extruded aluminum alloy can be freely designed and can be made lighter. Furthermore, the left and right side plate materials can be made of rolled aluminum alloy to further improve the design. Liberalization and weight reduction can be promoted.
