物に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a columnar structure composed of a plurality of cylindrical members joined together, such as a lightning rod, an antenna, a flagpole, a microwave tower, or an electricity tower. , relates to a columnar structure in which one end of a second cylindrical member having an outer shape that is approximately the same diameter or smaller than the first cylindrical member is fitted and joined to one end of the first cylindrical member.

大幅に重量が増大する欠点が有つた。 In this type of structure, in order to increase the rigidity of the cylindrical member without increasing the weight, it is conceivable to provide radial ribs inside the cylindrical member. Such radial ribs can be provided in the joint of the large-diameter cylindrical member in the small-diameter cylindrical member, but it is difficult to provide them at the joint of the large-diameter cylindrical member. It was hot. For this reason, since the rigidity of the large side cylindrical member at the joint part is weak, there is a risk that damage may easily occur at the joint part. Alternatively, it is necessary to lengthen the fitting length, which has the drawback of significantly increasing the weight at the joint.
本発明は、筒状部材の剛性を、その小径側でも
大径側でも、リブの有効利用によつて顕著に高め

である。 In order to achieve this object, the present invention provides a columnar structure in which one end of a second cylindrical member having a diameter substantially the same as or smaller than the inner diameter of the first cylindrical member is fitted and joined to one end of the first cylindrical member. [B] Ribs of the first cylindrical member, or A first notch is formed at the joining side end of the rib of the second cylindrical member and at the center in the radial direction to allow the end of the rib of the other cylindrical member to fit into it [C] A second notch is formed at the joining side end of the outer circumference of the second cylindrical member to allow the end of the rib of the first cylindrical member to fit thereinto. It has the configuration described.

合長さを長くする必要はなくなつた。 By configuring in this way, a rib can also be provided at the joint of the large-diameter cylindrical member, and
By setting the ribs on the large diameter cylindrical member side and the ribs on the small diameter cylindrical member in an engaged state in which they overlap in the cylinder axis direction, a strong reinforcing effect can be obtained by the cooperation of both ribs. Therefore, the rigidity of both members at the joint is increased, and the risk of damage at the joint is reduced, so it is no longer necessary to increase the wall thickness or lengthen the fitting length.
つまり、全体として軽量で、かつ、剛性の高い
柱状構造物が得られるようになつた。 In other words, it has become possible to obtain a columnar structure that is lightweight as a whole and has high rigidity.
