BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment in which a wall is constructed using a connecting tool of a formwork panel according to the present invention will be described with reference to the drawings. 1 is a perspective view showing an embodiment of a connecting tool of the present invention, FIG. 2 is a perspective view showing a construction method of a wall using the connecting tool, FIG. 3 is an enlarged view of a main part of FIG. 2, and FIG. It is a top view of FIG. In each of the above drawings, the connector 1 is for connecting the stacked form panel 10 and the adjacent form panels 10 to each other at the corners of the rectangular form panel 10. That is, the connecting tool 1 is composed of two panel supporting portions 2 and 2 and a connecting portion 4 connecting the panel supporting portions 2 and 2. The panel supporting portions 2 and 2 are formed by forming four L-shaped receiving portions 3 between two diamond-shaped flat plates, and the corner portions of the formwork panel 10 are housed in the respective receiving portions 3 and 3.
Therefore, the width of the receiving portion 3 is designed according to the thickness of the formwork panel 10.

The connecting portion 4 connects the panel supporting portions 2 and 2 at an interval between the form panel panels 10 and 10 installed facing each other, and the width W1 of the connecting portion has a width W1 of the form panel 1.
It is designed according to the distance W2 between inner walls of 0 (FIG. 2). Therefore, the respective panel supporting portions 2 and 2 correspond to the positions of the formwork panels 10 and 10 arranged to face each other and can receive the corner portions thereof. When constructing a wall, a large number of standing streaks 12 rising from the wall installation surface are arranged along the wall surface between the formwork panels 10 and 10, and
A plurality of lateral reinforcing bars (hereinafter, lateral bars 11) are arranged in the height direction so as to intersect with the rising bars 12 and concrete is poured.

The connecting tool 1 according to the present invention has a connecting portion 4 thereof.
In addition, the horizontal muscle 11 and the rising muscle 12 are fitted with fitting portions (hereinafter, the horizontal muscle fitting portion 5 and the rising muscle fitting portion 6). The horizontal streak fitting portion 5 is composed of three semicircular recesses formed on the upper surface and the lower surface of the connecting portion 4, and the horizontal streak 11 can be inserted into the recesses. A protrusion 5a extending toward the opposite side is formed on the opening side of the horizontal streak fitting portion 5,
As a result, the opening width D1 is formed to be slightly smaller than the diameter of the horizontal stripe 11. Therefore, the horizontal streak 11 is inserted while deforming the protruding portion 5a by pushing the lateral streak fitting portion 5 apart.

Two rising muscle inserting portions 6 are formed on one side surface side of the connecting portion 4, and like the transverse muscle inserting portion 5, the rising muscle inserting portion 6 can be inserted into the semicircular recess. A protrusion 6a extending toward the opposite side is formed on the opening side of the rising muscle fitting portion 6, so that the opening width D2 is formed to be slightly smaller than the diameter of the rising muscle 12.
Therefore, the standing-up muscle 12 is fitted into the standing-up muscle fitting portion 6 while pushing the protrusion 6a wide and deforming it. Normally, the horizontal muscles 11 and the rising muscles 12 are made of the same reinforcing bars, so that the lateral muscle fitting portions 5 and the rising muscle fitting portions 6 can have the same size and dimension. Further, the rising muscle fitting portion 6 may be formed in an annular shape as shown in FIG. 6, instead of the one having one side opened as in this example. In this case, it is necessary to insert the rising muscle fitting portion 6 from the upper end portion of the rising muscle 12, but the rising muscle 12 once inserted will not come off even if it receives a lateral impact.

The rising muscle fitting portion 6 is detachably attached to the connecting portion 4. As shown in FIG. 5, the rising muscle fitting portion 6 has a bottom portion configured as an insertion piece 6b with respect to the mounting hole 4a of the connecting portion 4, and the insertion hole 6b is elastically deformed inward while the insertion hole 6a is elastically deformed. 4a is inserted and fitted. Various other existing structures can be adopted as the attachment structure of the rising muscle fitting portion 6, and the connecting portion 4
It may be molded integrally with and not removable. It is also possible to form a plurality of insertion holes 4a on the side of the connecting portion 4 and attach the rising muscle fitting portion 6 to any of the insertion holes 4a in accordance with the position of the rising muscle 12. The connector 1 is preferably made of synthetic resin with some flexibility, but may be made of metal such as aluminum.

A procedure for constructing a wall using the connecting tool 1 having the above-mentioned structure will be described below. First, the formwork panels 10 and 10 facing each other with a certain interval are continuously installed and fixed in the wall surface direction on the base surface of the place where the wall is formed, and the connecting tool 1 is adjacent to the formwork panel 10. At the corners, the corners 10a at the tops of the adjacent formwork panels 10, 10,
10a is inserted and installed so as to be housed in the lower receiving portions 3 and 3 (see A portion in FIG. 2 and FIG. 3). In this state,
