DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting structure of a wall panel in which one wall panel is formed in an arc shape.
The present invention relates to a technique for easily increasing the connection strength and connection accuracy of an arc-shaped wall panel while simplifying a connection operation and simplifying a configuration of a connection fitting.

[0002]

2. Description of the Related Art Conventionally, a connection structure of a fence panel in which a buried portion 2 formed below a ground portion is buried in the ground and the buried portions 2 and 2 are connected to each other is shown in FIG. As shown in the drawing, the metal J is applied to the outer surfaces of the buried portions 2 and 2 of the two wall panels Aa and Ba, and the bolt 9 is inserted through the hole of the metal J.
Are screwed into the connection holes 6 of the wall panels Aa, Ba and connected, and then concrete is poured so as to fill the buried portions 2 and 2.

[0003]

However, in such a configuration, in the wall panel Aa in which the ground portion is formed in the arc-shaped portion 3, the buried portion 2 is also formed in an arc shape. In order to make the abutment J come into contact with the arc-shaped buried portion 2, the abutment J is formed flat, and the bolt 9 inserted into the through-hole is fenced so that the abutment J follows the arc. The screw must be screwed into the nut buried on the panel Aa side carefully, and the work requires careful consideration, and the screwing amount of the bolt 9 is unpredictable. When a gap is formed, the wall panel Aa unexpectedly moves by that much, and it becomes difficult to temporarily fix the position of the wall panel A having the arc-shaped portion 3a in a predetermined state. Such a movement of the wall panel Aa may be induced even when the concrete is poured, and there is a problem that it is difficult to connect the wall panel Aa having the arc-shaped portion 3a. Therefore, it is conceivable to bend the contact metal J side in an arc shape in advance so as to favorably follow the circular arc shape. In such a case, however, the shape of the metal contact J must be a special shape. There is a problem that the number of parts of the backing J and the cost thereof also increase.

The present invention has been made in view of such a problem, and an object of the present invention is to simplify the connection work and simplify the structure of the connection fitting, while improving the connection strength and strength of the arc-shaped fence panel. It is an object of the present invention to provide a wall panel connection structure that can sufficiently increase connection accuracy.

[0005]

A quadrangular prismatic connection square body 4 is formed, connection surfaces 4a, 4b, and 4c are formed on three outer peripheral surfaces of the connection square body 4, and both ends of the buried portion 2 of the other wall panel B are faced. Connection receiving surfaces 5a, 5b, 5c are formed on the three surfaces of the back surface and the end surface, respectively, and the connection surfaces 4a, 4b, 4c and the connection receiving surfaces 5a, 5c are formed.
A connection hole 6 is formed in each of the connection surfaces 4b and 5c, and the connection surface 4b and the connection receiving surface 5c selected at the time of connection are brought into surface contact with each other, and the other connection surfaces 4 which become substantially flush in this surface contact state
a and the connection receiving surface 5b are in contact with the connection pieces 8, 8
