このことは前述のように、モーメントの低い両端近傍で
は、部材断面が過剰寸法になっていることを意味する。2. Description of the Related Art Generally, a beam of a structure has a function of supporting both ends in a horizontal state and supporting a vertical load.
At this time, when a heavy object is put on the center, as shown in FIG. 3, the bending moment 3 applied to the beam 1 becomes maximum in the center cross section, and becomes zero at both ends 2, 2 'in the case of simple support. Therefore, in the case of beams, the central part is subjected to a particularly large load. Therefore, general members are designed according to the dimensions that can withstand the load in the central part, and the shape members having a uniform cross section are used as they are. Is the most.
This means that the cross section of the member is excessively large near both ends where the moment is low, as described above.

の多数の工程を経なければならない。[0003] As a result, the structure has an unnecessary weight, and not only the members are wasted, but also all the members supporting the members are large and the cost is high. On the other hand, in order to provide the minimum necessary cross section, a shape as shown in FIG.
It is known to combine 4 'and web 5 by cutting a plate and welding. However, in order to produce such a profile, a number of processes such as cutting, beveling for welding, welding, and shape correction must be performed.

To achieve this by expanding the height of the web. That is, the present invention has a plurality of slits periodically arranged parallel to the longitudinal direction of the web in a web having an I-shaped or C-shaped cross section, and the slits expand in the height direction of the web. The expanded metal material has a shape in which the height of the web has a gradient in the longitudinal direction.

(C) shows the case where the cross section is C type. The slits 6 are periodically arranged in the web 5 and are most widened at the center of the member, so that the two flanges 4, 4 'are formed.
The interval between them is the largest. In order to manufacture a shaped material having such a shape, for example, a slit is formed while attaching a large number of blades to upper and lower rolls and pressing the web, and immediately thereafter, a process of widening the flange interval is performed.

In FIG. 1, the upper surface of the flange 4 is a flat surface, but may be a convex surface like the lower surface of the flange 4 '. Further, if the present invention is applied to a structure in which the divided portion is joined at the center portion D and the divided portion is joined to another member, it is effective as a cantilever.

The present invention can be effectively used for parts that are subjected to external bending force, such as ordinary building beams, undercarriages of automobiles and door reinforcements, around the wings of aircraft, and bridge girder of bridges aiming to reduce weight in the civil engineering field. . As for the material, steel is often used for the purpose, but aluminum, titanium,
The same effect can be obtained by using other alloy materials.
