[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hollow structure used for a beam or a pillar of a building such as a house, or a beam or a pillar of a carport, a building in a bus stop or a station, an outdoor tower or the like.

2. Description of the Related Art As a hollow structure used for a beam or the like, a structure described in U.S. Pat. No. 4,713,924 is known. This structure is composed of a pair of profiles facing each other along the upper and lower sides in the longitudinal direction, and a corrugated plate fixed to both sides of these profiles by sandwiching bent portions along the upper and lower edges. The corrugated sheet is disposed so as to be continuous in the longitudinal direction along each of the above-mentioned shaped members. However, when manufacturing a structure such as a long beam, the shape member can correspond to the length of the structure, but a corrugated or flat plate material is used.
In some cases, it is not possible to cope with the situation and it is necessary to arrange a plurality of plate members in the longitudinal direction. For example, when the thickness of the plate material is 4 mm or more, it may be difficult to use a long material such as a coil when performing surface treatment such as painting on the plate material.

However, when a plurality of corrugated plates or flat plates are arranged in the longitudinal direction of a beam or the like, there is a problem that the strength of the beam or the like is reduced at the connection portion simply by making the corrugated plates or the flat plates adjacent to each other. Occurs. For this reason, it is conceivable to use a bolt or the like to fix a connection plate straddling the edges of both corrugated sheets or between flat plates, but no connection is made between the vertically adjacent shapes. There is a disadvantage that the strength of the beams and the like cannot be sufficiently compensated. In addition, the work of fixing the connection plate requires that the corrugated plates or the flat plates be adjacent to each other in advance, which requires a space, and the work of assembling and fixing each of the upper and lower sections becomes large-scale and complicated. There was also a problem.
