(17) is a tightening rod, which is provided with a screw hole (18) at the center of the base end face thereof, and a screw is formed at the tip end (not shown).
(23) is a synthetic resin bottomed cylindrical stopper that is driven into the sleeve (19) of the connector (a) after the mold is disassembled, and (C) is a concrete wall.

Next, the operation will be described. As shown in FIG. 6, the screw (8) of the separator (7) was screwed to the stopper (9) inside the female screw cylinder (6), and the screw (11) of the shaft foot (10) was screwed into the outside. After that, insert the shaft foot (10) into the through hole (14) and insert the plate-like protruding piece (20) of the connecting tool (a) into the heat insulating material (12).
The sleeve (19) is pushed into the inside of the heat insulating material (12) of the through hole (14), and the tip of the sleeve (19) is placed on the weir plate (13) and the lower surface of the seat plate (1). Apply each to the heat insulating material (12).

As in the conventional case shown in the figure, the nail (15) is inserted from the through hole seat (3) of the pedestal ( 21 ) into the heat insulating material (12) and driven into the weir plate (13) to insulate the connector (a). It may be temporarily fixed to the barrier plate (13) with the material (12).

(Effects of the Invention) The connector for concrete form clamping member of the present invention has the following remarkable effects.

(1) A sleeve is provided on the lower surface of the seat plate of the connector, the tip of the sleeve is applied to the dam plate of the form, and the seat plate is applied to the heat insulating material inside the dam plate to tighten the form. Therefore, (a) the thickness of the heat insulating material is held by the sleeve, and the wall thickness dimension can be accurately held because the coupling tool is less likely to be penetrated into the heat insulating material by overtightening the dam plate.

(B) The heat insulating material is not damaged by the connector, and the heat insulating performance of the heat insulating material is not impaired.

(2) Since several plate-like projecting pieces are provided radially on the outer peripheral surface of the sleeve below the seat plate of the connecting tool, when the connecting tool is attached, the radial plate-like projecting pieces dig into the heat insulating material. Therefore, (a) Since the radial plate-like projecting pieces of the connecting tool exert the effect of temporarily fixing the connecting tool without using the temporary fixing nail in the connecting tool, the temporary fixing nail is driven. And the workability is good because there is no need for the processing after dismantling the formwork.

(B) When tightening the weir plate by screwing the screw hole of the tightening rod into the screw of the shaft foot, the connector does not rotate together due to the contact resistance between the radial plate-like protruding piece of the connector and the heat insulating material. The plate can be tightened quickly and accurately.

(C) Since the projecting piece of the connecting tool is plate-shaped, the contact resistance of the projecting piece with respect to the heat insulating material is large, and co-rotation of the connecting tool can be reliably prevented.

(D) Since several plate-like projecting pieces of the connecting tool are provided radially, the contact resistance of the plate-like projecting pieces with respect to the heat insulating material acts evenly around the connecting tool, and the stability of the connecting tool is good.

(E) Since the plate-shaped projecting piece of the connector is integrally provided on the outer peripheral surface along the axial direction of the sleeve, even if it is thin, it has high strength and is difficult to break.

(F) Since the projecting piece of the connector is plate-shaped in the axial direction of the sleeve, the projecting piece can easily be embedded in the heat insulating material to facilitate the assembly of the mold.

(3) The post-treatment after disassembling the mold can be simply performed because the stopper is simply driven into the sleeve of the connector.

(4) It has a simple structure and can be manufactured easily and inexpensively.
