作業も頗るスムースになし得る。Effects of the invention As mentioned above, the formwork shoring according to the invention has a structure in which a horizontal pipe is provided protruding from the top and bottom of one side of the hollow prism, and a screw rod is screwed into this horizontal pipe. The support spacing can be set arbitrarily by advancing and retracting the support. Moreover, since the pad provided at the tip of the screw rod is rotatably attached to the screw rod, it is not affected by the rotation of the screw rod. Therefore, according to the formwork shoring of the present invention, the support spacing can be freely adjusted according to the position of the sheet piles, so one type of shoring is sufficient, and the work of adjusting the support spacing is also easy. It can be done smoothly.
また、本考案における水平管を、第１図に図示
したように中空角柱内に入り込むように設ければ
水平管の突出長さをそれだけ小さくでき、よりコ
ンパクトに構成できるという利点もある。 Furthermore, if the horizontal tube of the present invention is provided so as to fit inside the hollow prism as shown in FIG. 1, the protruding length of the horizontal tube can be reduced accordingly, which has the advantage of making the structure more compact.
殊に、本考案の型枠支保工においては、水平管

である。 In particular, in the formwork support of the present invention, a grease injection hole is provided in the horizontal pipe, so if grease is injected through this injection hole, the threaded rod will not only rotate smoothly during use but also during storage. Effective in preventing rust.
更には、中空角柱の下端には水抜き孔を設けた
から、使用中に水侵入があつても使用後に中空角
柱の上端に設けたフツクを引つ掛け支持させてお
けば完全に水抜きでき（この場合、水平管に設け
たグリス注入孔が水抜きの補助をするから、型枠
支保工を振り回して水抜きする必要はない）、錆
化を充分防止することができ保管上有利である。
従つて、本考案の型枠支保工は長期間の使用・保
管によく耐え経済的でもある。 Furthermore, since a drainage hole is provided at the bottom end of the hollow prismatic column, even if water gets in during use, the water can be completely drained by hooking the hook provided at the top end of the hollow prismatic column to support it after use. In this case, since the grease injection hole provided in the horizontal pipe assists in draining water, there is no need to swing the form support to drain water), and rusting can be sufficiently prevented, which is advantageous in terms of storage.
Therefore, the formwork support of the present invention can withstand long-term use and storage, and is also economical.
