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.

摘要： PURPOSE: To maintain a form at a specific interval by means of a separator and a form fastener in order to execute cast-in-place concrete. CONSTITUTION: A nut 2 screwing the end 10 of a separator 1 therein is held to one end of a holder 3 in a state to stop turning. A sleeve 4 is provided with sufficient strength necessary for bearing a form 8 and, at the same time, it is formed of synthetic resin with less adhesion to concrete 70. The inside end of the sleeve 4 is concentrically placed to the nut 2 and is held to the other end of the holder 3. The axial center 5 inserted in the sleeve 4 and connecting one end 50 thereof to the nut 2 with a screw is projected from the form 8, the outside end 41 of the sleeve 4 is brought into contact with the form 8, and a form fastener 7 is fastened to the projected end 51 of the axialcenter 5. A form anchorage device is a simple construction without requiring any plate-nut, concentricity and air-tightness between members are maintained to surely hold the form, and the sleeve and axial-center are simply drawn out after the stripping.
