Description
【考案の詳細な説明】 本考案は鉄塔用ステツプボルトに係わる。[Detailed explanation of the idea] The present invention relates to a step bolt for a steel tower.
鉄塔組立に際して、鉄塔主柱材に孔明けし、ス
テツプボルトを固定して組立作業の便をはかつて
いるが、鉄塔組立後は昇降脚となるもの以外は抜
いている場合が多い。 When assembling a steel tower, holes are drilled in the main pillar material of the steel tower and step bolts are fixed to facilitate assembly work, but after the tower is assembled, everything except the legs that will serve as the elevating legs are often removed.
このように従来の鉄塔組立においては、ステツ
プボルトを固定するため、鉄塔の主柱材に孔明け
を要し、それだけ工数が増加し、一方組立時以外
不要となる箇所に多くの孔明けすることは、それ
だけ鉄塔強度が低下することにもなる。また組立
後不要となつたステツプボルトを残しておけば、
人が鉄塔にのぼる恐れも生じる。 In this way, in conventional steel tower assembly, holes are required to be drilled in the main pillar material of the steel tower in order to fix the step bolts, which increases the number of man-hours accordingly, and also requires drilling many holes in locations that are unnecessary except during assembly. This will also reduce the strength of the steel tower. Also, if you leave the step bolts that are no longer needed after assembly,
There is also a risk that people will climb onto the steel tower.
そこで、本考案はステツプボルトを鉄塔主柱材
である支持体、例えば山形鋼に着脱できるように
し、支持体に孔を明けることなく、取付け、取り
はずしできる鉄塔組立用ステツプボルトを提供す
るものである。 Therefore, the present invention provides a step bolt for assembling a steel tower that can be attached to and removed from a support that is the main pillar material of a steel tower, such as angle iron, and that can be installed and removed without drilling holes in the support. .
以下図面に示す実施例について説明する。 The embodiments shown in the drawings will be described below.
第１図は本考案の一実施例の上面図であり、第
２図は第１図実施例の側面図である。 FIG. 1 is a top view of one embodiment of the present invention, and FIG. 2 is a side view of the embodiment of FIG.

れた構成となつている。 The step bolt 1 has a step portion up to an intermediate position, and the remaining portion is threaded to form a support portion. The eyebolt 2 has a hole at one end and is threaded at the other end.

平のステツプボルトを固定することができる。 The nut 5 is screwed onto the threaded step bolt 1, and the step bolt 1, which has a step portion and a support portion, is fitted into the hole of the eye bolt 2 from the side of the support portion, resulting in an assembly that has a T-shape. along both sides of the angle iron indicated by 6, each has an insertion hole into which the step bolt 1 and the eye bolt 2 are fitted, and a stopper 3 having an engaging part 7 for the edge of the angle iron 6 is attached to the support part of the step bolt 1. By inserting the eye bolt 2 from the other end side, engaging it with the edge of the angle iron 6, and tightening each with the nuts 4, a horizontal step bolt can be formed using the angle iron, which is the main pillar material of the steel tower, as a support. can be fixed.

所に固定することができる。また以上の説明から
理解されるように取りはずしも簡単にできる。 Such step bolts 1 and eye bolts 2 may be prepared in different sizes depending on the cross-sectional size of the angle iron, and can be fixed at necessary locations in assembling the steel tower. Furthermore, as can be understood from the above explanation, it can be easily removed.
更に、ナツト５は螺合によりステツプボルト１

テツプ部の長さを調整することができる。 Furthermore, the nut 5 is screwed into the step bolt 1.
Since an arbitrary position can be taken and maintained on the threaded support part of the step bolt 1, if the length of the support part of the step bolt 1 is made large, the length of the step part can be adjusted by adjusting the position of the nut 5.
