【産業上の利用分野】本発明は、中空角材およびこれを
含む構造体に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hollow square bar and a structure including the same.
【0002】[0002]
【従来の技術】住宅の窓等の外側には、防犯等のため

固定したものである。2. Description of the Related Art A surface lattice is installed outside a house window or the like for crime prevention. This surface lattice is formed by arranging a plurality of hollow square members having a rectangular cross section in the vertical direction and the horizontal direction, and fixing the hollow square members with a fixture such as a screw (a screw) or a bolt.
【0003】しかしながら、このような面格子では、ね
じ等の固定具の端部が外表面に露出しているため、美的
外観を損なうという問題がある。However, such a surface lattice has a problem in that the end portion of a fixture such as a screw is exposed on the outer surface, which impairs the aesthetic appearance.
【0004】そこで、ねじ等の固定具を中空角材の内側
から固定し得るように、面格子の組立時に、一対の条材
(長尺部材)を結合して中空角材とする方法が提案され
ている。この場合、図9に示すように、一対のコ字状の
条材(長尺部材)101、102の縁部同士をつき合わ
せ、これらを接着して中空角材100を構成する方法
や、図10に示すように、一方のコ字状の条材104を
他方のコ字状の条材105の内側に挿入し、これらを接
着して中空角材103を構成する方法が考えられる。Therefore, a method has been proposed in which a pair of strips (long members) are joined to form a hollow square bar during the assembly of the surface lattice so that a fixture such as a screw can be fixed from the inside of the hollow square bar. There is. In this case, as shown in FIG. 9, a pair of U-shaped strips (long members) 101, 102 are abutted with each other at their edges, and these are bonded together to form the hollow square bar 100, and FIG. As shown in FIG. 5, a method of inserting one U-shaped strip 104 inside the other U-shaped strip 105 and adhering these to form the hollow square bar 103 can be considered.

こともある。However, in the former method, since the boundary line 34 between the strips 101 and 102 appears on the outer surface of the hollow square bar 100, the aesthetic appearance is also impaired, and in the latter method, the end face of the outer strip 105 ( Machining accuracy is poor) 106
Are exposed and impair the aesthetic appearance as well. Further, these methods also have a problem in that it is difficult to align the strips when they are joined to each other, and a positional shift easily occurs. When the strips are misaligned with each other, their boundaries are conspicuous, which further impairs the aesthetic appearance and may give anxiety to the product.
