本考案は、吊橋ケーブル架設用のキヤツトウオ
ークの手摺支柱に関する。[Detailed Description of the Invention] The present invention relates to a handrail support for a catwalk for installing suspension bridge cables.
第１図で示す如く対岸の橋台１，２間に主塔３
が構築された吊橋を構成する場合、ケーブル架設
用足場としてキヤツトウオーク４が設けられる。 As shown in Figure 1, the main tower 3 is located between the abutments 1 and 2 on the opposite bank.
When a suspension bridge is constructed, a cat walk 4 is provided as a scaffold for installing cables.
該キヤツトウオーク４は第２図、第３図で示す
如く床組５と安全対策としての手摺装置６とから
主構成され、床組５上に小物落下防止対策として
合繊ネツトを敷設している。 As shown in FIGS. 2 and 3, the catwalk 4 mainly consists of a floor assembly 5 and a handrail device 6 as a safety measure, and a synthetic fiber net is laid on the floor assembly 5 to prevent small objects from falling. .

とする。 Therefore, the present invention was devised to solve the problems of the conventional example, and the handrail ropes 18 are erected at predetermined intervals in the bridge axis direction on both sides of the suspension bridge cable erection cat walks. In a handrail post 14 of a catwalk to which a rope support rod 15 for supporting and connecting is fixed, the rope support rod 15 is attached to the handrail support 14 only on one end side.
The handrail support rod 14 has a free end that can be engaged with a tool 20 for winding and grasping the rope support rod 15 around the handrail rope 18 at the other end that protrudes to the outside of one side of the handrail support rod 14. In order to allow the handrail rope 18 to be temporarily placed between the rope support rod 15 and the handrail support 14, a bending fulcrum portion 17 is formed in the middle of the rope support rod 15 in the longitudinal direction and in the outer area of one side of the handrail support 14. It is characterized by
以下、第５図乃至第７図を参照して本考案の実
施例を詳述する。 Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 5 to 7.
第５図、第６図は第１実施例を示し、１４は手
摺支柱であり、キヤツトウオークの両側、即ち、
床組の両側に橋軸方向所定間隔ごとに立設固定さ
れ、本例では手摺支柱１４はアングル材でしめし
ているがその断面形状は円形、箱形、平板形等任
意である。 5 and 6 show the first embodiment, 14 is a handrail support, which is placed on both sides of the catwalk, i.e.
They are erected and fixed on both sides of the floor assembly at predetermined intervals in the axial direction of the bridge, and in this example, the handrail supports 14 are made of angle material, but their cross-sectional shape may be arbitrary, such as circular, box-shaped, flat plate, etc.
１５はロープ支持棒であり、その一端側が手摺

には屈曲支点部１７が形成され、第５図の第１実
施例では屈曲支点部１７は90°とされ、棒他端側
が支柱長手方向上向として延設されている。 The rope support rods 15 are fixed in the longitudinal direction of the handrail support column 14 in, for example, three stages, but at the middle of each rope support rod 15 in the longitudinal direction, there is an outer area on one side of the handrail support column 14 (both on the floor assembly side and on the cross-floor assembly side). )
A bending fulcrum portion 17 is formed in the rod, and in the first embodiment shown in FIG. 5, the bending fulcrum portion 17 is at 90°, and the other end of the rod extends upward in the longitudinal direction of the support.
又、第７図の第２実施例では屈曲支点部１７は
130°程度とされ、棒他端部が上向に延設されてい
る。 In addition, in the second embodiment shown in FIG. 7, the bending fulcrum portion 17 is
The angle is approximately 130°, and the other end of the rod extends upward.
即ち、要はロープ支持棒１５上の屈曲支点部１
７と支柱１４間に手摺ロープ１８を仮置きできる
形状であればよい。 That is, the point is that the bending fulcrum part 1 on the rope support rod 15
Any shape is acceptable as long as it allows the handrail rope 18 to be temporarily placed between the support 7 and the support 14.
ここで、仮置とは、手摺ロープ１８の中間を屈
曲支点部１７に対して上方から挿入させたとき、
該ロープ１８が手摺支柱１４から離反するのを防
止することを意味している。 Here, temporary placement means that when the middle of the handrail rope 18 is inserted into the bending fulcrum part 17 from above,
This is meant to prevent the rope 18 from separating from the handrail post 14.

８を掴持すべく第６図に示す如く折曲させること
により、巻回部２１を介して支柱１４に固定され
るのである。 Therefore, the handrail rope 18 temporarily placed on the rope support rod 15 is connected to the other end of the rope support rod 15 by a worker on the floor assembly of the catwalk with the tool 20 attached via the string 19. Insert it as shown in the figure,
The handrail rope 1 is bent around the bending fulcrum part 17 in the direction of the arrow.
8 is fixed to the support column 14 via the winding portion 21 by bending it as shown in FIG.

利用できる。 At this time, the bending fulcrum portion 17 may be made of any material that can withstand at least two or more bends of the handrail rope, such as gripping and releasing, and can be plastically deformed. A flat metal bar etc. can be used.
なお、ロープ支持棒１５の折曲角度は図示の
130°や90°の他、45°等のような折曲角度であつて
もよい。 Note that the bending angle of the rope support rod 15 is as shown in the figure.
In addition to 130° or 90°, the bending angle may be 45° or the like.
本考案は以上の通りであり、手摺支柱１４にロ
ープ支持棒１５の一端側が固着されているので、
これは工事現場でその都度固着するものに比べ、
製作費、作業コストが大巾に節減できる利点があ

支持棒１５の落下は一切なく危害を与える心配も
ない。 The present invention is as described above, and since one end of the rope support rod 15 is fixed to the handrail post 14,
This is compared to something that sticks each time at a construction site.
It has the advantage of greatly reducing production costs and work costs, and since it is a factory-produced type, there is no possibility that the rope support rod 15 will fall at the construction site, and there is no risk of harm.

た上での施工工期の短縮化を図ることができる。 Further, according to the present invention, the bending fulcrum portion 17 is formed midway in the longitudinal direction of the rope support rod 15,
The handrail rope 18 can be gripped by temporarily placing the handrail rope 18 on the rope support rod 15 and wrapping the free end of the rope support rod 15 around the handrail rope 18 once using the tool 20. So,
Even if the cross-sectional diameter of the handrail rope 18 is slightly different, the handrail rope 18 can be securely wound and gripped, and the handrail rope 18 can be attached so as to prevent the rope 18 from sliding against each handrail post 14 in the longitudinal direction. The installation work can be carried out more quickly and safely than in the past without causing any small objects to fall, and as a result, the construction period can be shortened while ensuring safety.
