Description
【発明の詳細な説明】 （産業上の利用分野） 本発明は切梁の長さ調整構造に関するものである。TECHNICAL FIELD The present invention relates to a length adjusting structure for a beam.
（従来の技術） 従来において山留支保工の切梁は現場の土留壁間隔にそ
の寸法を一致させねばならないことから長さの微調整が
必要となりこのためジャッキ及び補助ピースを介装する
等の方法が用いられていた。(Prior Art) In the past, the beam of the Yamadome shoring has to be sized to match the space between the soil retaining walls at the site, so it is necessary to make fine adjustments to the length. For this reason, jacks and auxiliary pieces must be inserted. The method was used.
（発明が解決しようとする課題） 本発明は以上の従来の課題を解決し切梁の長さの微調整
を容易にする切梁の長さ調整構造の提供を目的とする。(Problems to be Solved by the Invention) An object of the present invention is to provide a cut beam length adjusting structure that solves the above conventional problems and facilitates fine adjustment of the cut beam length.
（課題を解決するための手段） 本発明は以上の目的達成のために 1.外筒体内に伸縮可能に装着された内筒体と、前記外筒
体内において内筒体と反対側に装着されたジャッキと、
スペーサーを出し入れする外筒体の開口とからなるジャ
ッキブロックを切梁の間に介装した切梁の長さ調整構造 を提案するものである。MEANS FOR SOLVING THE PROBLEMS The present invention is to achieve the above objects. 1. An inner cylinder body that is extendably and retractably mounted in an outer cylinder body, and is mounted on the opposite side of the inner cylinder body in the outer cylinder body With a jack,
We propose a structure for adjusting the length of a cutting beam, in which a jack block consisting of an opening of an outer cylinder for inserting and removing a spacer is interposed between the cutting beams.
（作用） （１）本発明の調整構造は特にジャッキが備えられてい
るため切梁の長さの微調整は容易である。(Operation) (1) Since the adjusting structure of the present invention is particularly provided with the jack, the fine adjustment of the length of the cutting beam is easy.
（２）本発明の調整構造は特に外筒体にスペーサーを出
し入れする開口が設けられるためジャッキのストローク
がわずかでも大きな寸法調整が出来従来のような補助ピ
ースが不要となる。(2) Since the adjustment structure of the present invention is provided with the opening for inserting and removing the spacer in the outer cylinder body, a large size adjustment can be performed even with a slight stroke of the jack, and the conventional auxiliary piece is unnecessary.
（実施例） 以下本発明の切梁の長さ調整構造を図面に示すに実施例
に従い説明する。(Embodiment) A length adjusting structure for a beam according to the present invention will be described below with reference to an embodiment shown in the drawings.
第１図及び第２図は本発明の切梁の長さ調整構造を示
し、該調整構造は切梁（３）の間に介装されたジャッキ
ブロック（４）を有する。FIGS. 1 and 2 show a length adjusting structure for a truss of the present invention, which has a jack block (4) interposed between the trusses (3).
該ジャッキブロック（４）は外筒体（５）内に伸縮可能
に装着された内筒体（６）を有する。The jack block (4) has an inner cylinder body (6) mounted in an outer cylinder body (5) so as to be capable of expanding and contracting.
更に前記外筒体（５）内には内筒体（６）と反対側にジ
ャッキ（７）が装着される。Further, a jack (7) is mounted inside the outer cylinder (5) on the side opposite to the inner cylinder (6).
次に前記内筒体（６）とジャッキ（７）の間には外筒体
（５）に開口（5a）が設けられてスペーサー（８）の外
筒体（５）内への出し入れを可能にしている。Next, an opening (5a) is provided in the outer tubular body (5) between the inner tubular body (6) and the jack (7) to allow the spacer (8) to be taken in and out of the outer tubular body (5). I have to.
以上の実施例に示した本発明の切梁の長さ調整構造の起
能は次の通り。The functions of the length adjusting structure for a truss of the present invention shown in the above embodiment are as follows.
すなわち切梁（３）の間にジャッキブロック（４）が介
装されるが調整すべき切梁（３）の長さに近くなる様に
スペーサー（８）を外筒体（５）内に入れる。That is, the jack block (4) is interposed between the cutting beams (3), but the spacer (8) is inserted into the outer cylindrical body (5) so that it is close to the length of the cutting beams (3) to be adjusted. .
これにより内筒体（６）はスペーサー（８）の寸法だけ
外筒体（５）から突出する。As a result, the inner cylinder (6) projects from the outer cylinder (5) by the size of the spacer (8).
次にジャッキ（７）を駆動して内筒体（６）を押し出し
切梁（３）の長さの微調整を行うのである。Next, the jack (7) is driven to push out the inner cylindrical body (6) to finely adjust the length of the cross beam (3).
（発明の効果） 本発明の切梁の長さ調整構造の実施例は以上の通りであ
りその効果を次に列記する。（１）本発明の調整構造は
特にジャッキが備えられているため切梁の長さの微調整
は容易である。(Effects of the Invention) The embodiments of the beam length adjusting structure of the present invention are as described above, and the effects thereof are listed below. (1) Since the adjusting structure of the present invention is equipped with a jack, it is easy to finely adjust the length of the cross beam.
（２）本発明の調整構造は特に外筒体にスペーサーを出
し入れする開口が設けられるためジャッキのストローク
がわずかでも大きな寸法調整が出来従来のような補助ピ
ースが不要となる。(2) Since the adjustment structure of the present invention is provided with the opening for inserting and removing the spacer in the outer cylinder body, a large size adjustment can be performed even with a slight stroke of the jack, and the conventional auxiliary piece is unnecessary.
