。By the way, among the above-mentioned specific assembly members, a coupling tool as shown in FIG. 6 is known. This connector is a member used to connect each support rod that supports the formwork from the inside and outside. This connector has a truncated conical shape with a male screw protruding from the bottom and a female screw carved into the top. Insert the male screw side into the hole drilled in the formwork, let the tip side of the male screw protrude to the outside of the formwork, screw the external support rod onto the protruding male screw, and connect the internal support rod to the outside. The support rods were connected.

もあった。However, conventional connectors have the disadvantage that when the external support rod is screwed into the male screw of the connector that protrudes to the outside of the formwork, it spins idly, making it impossible to screw the external support rod. Therefore, it was necessary to hold the coupling device by hand to prevent it from spinning idly. However, because the side for attaching the coupler and the side for attaching the external support rod were completely separated by the formwork, the same person could hold the coupler with one hand while holding the external support rod with the other hand. It was not possible to perform the work of threading the male screw, and as a result, there was an inconvenience that the above work could not be carried out without at least two people. In addition, the connectors that protruded to the outside of the formwork sometimes fell out of the formwork, and for this reason, workers sometimes had to support the connectors attached to the formwork to prevent them from falling out. .
本発明は、上記のような問題点に鑑み、その問題点を一

１７側に突設させる構成でもよい。The screw member 16 inserted and fixed from the top surface 17 to the bottom surface 18 of the outer peripheral member 15 of the connector 11 has a female screw 16a.
and a female screw 16b are respectively formed. 1j1 screw 1
6a is formed on the tip side of a screw member I6 that vertically passes through the bottom surface 18 of the connector 11 and projects to the outside of the connector 11. That is, the male screw 16a is formed on the bottom surface 18 side. On the other hand, the female screw 16b is carved perpendicularly to the top surface 17 on the base end side of the screw member 16, that is, on the top surface 17 side of the connector 11. The male screw 16a is inserted through a hole 20 drilled in the formwork 12 and screwed into the external support rod 14 attached to the outside of the formwork 12 to connect with the external support rod 14. Therefore, the amount of protrusion of the screw member 16, on which the female screw 16a is formed, from the bottom surface 18 of the connector 11 is greater than the thickness of the formwork 12. Further, an internal support rod 13 attached to the inside side of the formwork 12, that is, the side into which concrete will be poured in the future, is screwed into the female screw 16b and connected to the internal support rod 13. As shown in FIG. 5, a male screw may be provided protruding from the top surface 17 of the connector 11 instead of the female screw 16b.
次に、上記実施例の構成に基づく連結具を使用して、型
枠を組み立てる場合にについて以下説明する。Next, the case where a formwork is assembled using the connector based on the configuration of the above embodiment will be described below.

するために他の作業者がこれを支持する必要もない。Normally, the connectors 11 are screwed onto both ends of the internal support rod 13 in advance, so when driving the nails 19 of the connector 11 into the formwork 12, the nails 19 attached to the ends of the internal support rods 13 on the opposite side need to be screwed together. The connector 11 is fixed to the formwork 12 by hitting the tip of the male screw 16a of the connector 11 with a hammer. The above-mentioned attachment method is to horizontally attach the internal support rods 13 to one of the formworks 12 via the connectors 11. Since the connecting tool 11 is fixed to the formwork 12 by the nails 19, the male screw of the connecting tool does not get used to coming out of the hole 20 as in the conventional case. There is no need for other workers to support this to prevent it from slipping out.
その後に、内部支持棒１３の先端に螺合されている他の
連結具１１に他の型枠１２を取り付ける。After that, another formwork 12 is attached to another connector 11 screwed onto the tip of the internal support rod 13.

１２を組み付けて立てる。For installation, the other formwork 12 to be installed is brought close to the tip of the internal support rod 13 that has already been horizontally attached to one formwork 12, and the formwork 12 is pre-drilled at a predetermined position. The female screw 16a of the connector 11 screwed onto the tip of the internal support rod 13 is inserted into the provided hole 20, and then the area around the hole 20 is tapped from the outside of the formwork 12 to complete the connection. A nail 19 protruding from the bottom surface 18 of the tool 11 is driven into another formwork 12, and the other formwork 12 is assembled to the tip of the internal support rod 13 and erected.

3 and an external support rod 14 are connected via a connecting tool 11. When the external support rod 14 is screwed onto the male screw 16a of the connector 11, the connector 11 is fixed to the formwork 12, so the connector 11 does not rotate idly, and therefore, unlike the conventional case, other There is no need for the operator to be inside the formwork 12 and hold down the connector 11 with his/her hands. Thereafter, the external support rod 14 connected to the internal support rod 13 is assembled to the shoring horizontally or vertically assembled outside the formwork I2, and is fixed to the shoring by tightening with nuts. In this way, the formwork 12 is assembled while being supported by shoring via the internal support rods 13 and external support rods 14 that support the formwork 12 from the inside and outside.
型枠１２の解体は次のようにして行われる。The formwork 12 is dismantled as follows.
外部支持棒１４を支保工に固定していたナンドを取り外

の軽減に寄与している。The removal work is performed by turning the external support rod 14 in the opposite direction to the screwing direction, and the external support rod 14 is attached to the male screw 16.
It comes off easily from a. Connect all the external support rods 14 to the connector 1
After removing the male screw 16a from No. 1, the formwork 12 is removed. At this time, if the adhesion force of the concrete is stronger than the adhesion force of the nails 19 driven into the formwork 12, the connector 11, which was fixed to the formwork 12 by the nails 19, will come off the formwork 12 and the hardened concrete surface. It remains embedded in the Conversely, if the adhesion force of the nail 19 driven into the formwork 12 is stronger than the adhesion force of concrete, the connector 11 is attached to the formwork 1.
It comes off from the concrete surface while being fixed to 2. If the connector 11 remains embedded in the concrete surface, the connector 11 can be rotated using a predetermined tool and removed from the concrete surface. In this way, the disassembled connector 11 is used many times, contributing to a reduction in construction costs.
