It is crushed at the bent portion 112,
The original strength of the corrugated sheet is considerably reduced. Moreover, in order to obtain the bent portion 112 having the S-shaped cross section, a dedicated bending device is required, and the cost is increased. On the other hand, the inventors fit a corrugated plate having a vertically corrugated cross section between a pair of upper and lower profiles facing each other, into concave grooves provided on both sides of the facing surface of each profile, There has been proposed a hollow structure in which the fitting portion is connected and fixed at equal intervals by a punch from the side (Japanese Patent Application No. 8-10544). However, the connection by the above-mentioned crimping is remarkable when the corrugated plate is deformed at the crimping portion, particularly in the case of a large structure. Such deformation may also impair the strength of the corrugated sheet in the corrugated uneven cross section direction. Moreover, between the caulked portions, the corrugated sheet is free within the concave groove of each profile, and there is a gap between the concave groove of the profile and the corrugated plate, except for the caulked portion and the convex portion of the corrugated plate. Exists. Rainwater, dust, and the like enter these gaps, and are apt to be stained in the vicinity.

る変形抵抗をも高めることが可能になる。The beam 60 shown in FIG. 4C uses an extruded profile having a hollow portion in the upper and lower profiles 62. Each profile 62
An extruded member is used in which a pair of ribs 66 are vertically provided at both ends of a surface facing each other of a rectangular hollow portion 64 and a concave groove 68 is formed between them in the entire length. The corrugated plate 10 is fixed between the concave grooves 68 by the bolts 30 via the corrugated spacers 20. Such a beam 60 includes upper and lower profiles 6.
Since the hollow portion 64 has the entire length of the hollow portion 2, deformation resistance against a load in the vertical direction can be further increased. The beam 70 shown in FIG. 3D uses an extruded profile in which a hollow portion 74 and a horizontal flange 75 are provided in the upper and lower profiles 72. Each of the profile members 72 has a flange 75 extending horizontally at the upper corner or the lower corner of both sides of the rectangular hollow portion 74. Incidentally, reference numeral 76 denotes a pair of ribs, and a concave groove 78 therebetween. Then, similarly to the above, the corrugated sheet 10 is fixed between the two by the bolt 30 via the corrugated spacer 20. The beam 70 has a hollow portion 7 above and below.
4 and the flanges 75 extend to the respective corners, so that the deformation resistance to a torsional stress as well as the deformation resistance to a load in the vertical direction can be increased.

容易に組立を行うこともできる。According to the hollow structural member of the present invention described above, the corrugated plate fixed on both sides between the pair of profiles is fixed without being deformed by the presence of the corrugated spacer, and the corrugated plate is originally formed. It is possible to provide a lightweight structural material having the strength in the cross-sectional direction of the corrugated unevenness. Further, the size and strength of the structural material can be freely designed by changing the dimensions of the shape member and the corrugated sheet. Furthermore, profiles, corrugated sheets,
In addition, hollow beams and columns can be obtained by simple processing such as drilling, bolting, and screwing in the corrugated spacer, or simply by applying an adhesive. In addition, since no special equipment or jigs and tools are required, and no space is required, assembly can be easily performed even on the site.

きる。Furthermore, since the gap between the concave groove of the profile and the corrugated plate is filled with the corrugated spacer, the intrusion of rainwater and dust can be prevented, and the corrosion and dirt of the hollow structural member can be suppressed.
In addition, since the corrugated plate is inserted into the concave groove of the profile through the corrugated spacer, a relatively large width may be used. This is advantageous particularly when an extruded profile is used. In addition, when an aluminum alloy material is used for the shape portion, a free and complicated cross-sectional shape can be obtained by employing the extruded shape material. In addition, when used as a structural material such as a beam, various functions can be imparted by devising the shape of the shape portion.
