摘要： PROBLEM TO BE SOLVED: To smoothly let the air out of an form when concrete is placed in the segment form using a steel shell segment. SOLUTION: An air vent pipe 26 is mounted to the upper part of the inside of a steel shell segment 21. One end of the air vent pipe 26 is located to a position near to the inside of an upper surface wall 24 of the steel shell segment 21 and is made to down from that position, and the other end passes under an inward flange 25. A front form 30 having a hole 32 for the front end of the lower side of the air vent pipe 26 to face thereto is mounted to the front of the steel shell segment 21, and an outside exhaust pipe is connected to the front end of the lower side of the air vent pipe 26. Concrete is placed from a concrete inlet 31. When concrete is placed. air in the form is exhausted to the outside from the air vent pipe 26 and outside exhaust pipe. Even if the steel shell segment 21 is provided with the inward flange 25 to the circumferential edge of the front opening, air is surely exhausted without being prevented from the inward flange 25, and a vertical casting system for casting concrete can be adpted by making the steel shell segment 21 as the vertical.

摘要： PROBLEM TO BE SOLVED: To make the construction work easier in a narrow space when clamping from the outer periphery for reinforcing a rectangular column formworks. SOLUTION: A formwork clamp device comprises two lateral joists 11 facing each other around the rectangular column formwork 8 and two lateral joists 12 facing each other is the direction perpendicular to the joints 11. Each lateral joist 11 or 12 comprises a lever member 15 or 18 contacted to the outer surface of the column formwork 8 and a truss 17 or 20 fixed to the outer side surface of the lever member 15 or 18 in a detachable manner. Connections of these members are performed with bolts and nuts for example. The lateral joists 11 and 12 have trusses 17 or 20 in construction so that a sufficient strength can be obtained with a light weight. Also, the trusses 17 and 20 can be separated from the lever members 15 and 17, so that individual member can be made to a small size and a light weight. Therefore, even tough a working area is narrow as in the case where scaffolding for frameworks is located around it, the members can be carried in easily and the work can be performed easily. If the trusses 17 and 18 are made of a plurality of truss pieces 16 and 19 in construction, then individual member can be made much lighter.
