掛け渡すようになっている。2. Description of the Related Art As shown in FIG. 2, in a frame scaffold A, pins C and C are horizontally provided above and below the building site of a building frame B, and the adjacent building frames B and B are adjacent to each other using the pins. The braces D and D are laid between them.

く、次回の使用に不都合を来すことになる。However, the pin holes formed at the ends of the braces D and D are caused by a slight deviation between the intervals between the adjacent building frames B and B and the lengths of the braces D and D. It may be difficult to fit the pins C and C, and in this case, it is the actual situation that the pins are hammered in and forcibly delivered. Therefore, the pins C, C, etc. are bent, making them unsafe, and disassembling becomes more difficult, as well as making it inconvenient for the next use.

a, 3bを付設したことを特徴とする。According to the present invention, there is provided a threaded cylinder 1 in which one half is formed into a left-hand thread and the other half is formed into a right-hand thread, and a half-threaded threaded rod 2a is formed in one half of the threaded cylinder. A screw bar 2b having a right-hand thread formed on the other half is screwed to form a telescopic bar X into which both screw rods 2a and 2b move in and out by rotation of the screw cylinder 1 to one side or the other.

合よい状態にまで建枠Ｂ，Ｂ相互間の間隔を調整する。With the above construction, when the braces D and D are attached to and detached from the pins C and C, as shown in FIG. 2, the engaging frames 3a and 3b at both ends of the adjacent building frames B and B are mutually attached. Are engaged with each other to extend and contract the expansion bar X, and the screw cylinder 1 is appropriately rotated to one side or the other side to expand or contract the expansion bar X, and the building frames B and B are mutually connected to a state convenient for attaching and detaching the braces D and D. Adjust the spacing between.

先端部に固定した係合金物である。In the figure, 1 is a steel threaded cylinder in which one half is formed as a left-hand thread and the other half is formed as a right-hand thread, and 2a and 2b are steel threads formed in a left-hand thread that is screwed into one half of the threaded cylinder. And a steel threaded rod formed with a right-hand thread that is screwed into the other half, and these constitute a telescopic bar X into which both threaded rods move in and out when the threaded barrel rotates to one side or the other. is doing. Reference numerals 3a and 3b are engagement metal members fixed to the respective tip portions of the two screw rods 2a and 2b.
【０００９】螺筒１には、中央に横孔11を穿設し、鋼棒
