The jointer 7 penetrates the hole 6 of the rubber packing 4, extends on both sides, and is inserted into the recess 3 of the main body 1. Then, the connecting pin 10 is inserted from the connecting pin insertion hole 8 formed on the upper surface of the end of the main body 1 into the vertical hole 9 of the jointer 7, and is driven until the tip of the connecting pin 10 reaches the lower surface of the main body 1, 1. It has a structure to connect.

られている。FIG. 2 is a vertical sectional view showing details of the connecting portion. As shown in the figure, on the inner surface of the vertical hole 9 of the jointer 7,
A guide 11 is formed for inclining the tip end direction of the connecting pin 10 toward the outer side of the main body 1 when the connecting pin 10 is inserted from the connecting pin insertion hole 8 of the main body 1. In the example shown in the figure, a mountain-shaped protrusion having a center protruding outward of the main body 1 (the direction in which the rubber packing 4 is located) is provided as the guide 11 so that it can be used even when the jointer 7 is turned upside down. There is.

A slope 13 is formed on the inner surface of the hole 12 as shown in the figure. The slope 13 has the tip 10a of the connecting pin 10 inserted by the guide 11 of the jointer 7 in a state in which the tip is inclined toward the outside of the main body 1 inward of the main body 1 (away from the rubber packing 4). It is meant to guide you. In this example, the connecting pin insertion hole 8 on the upper surface and this hole 12 have the same shape, and can be used even when the main body 1 is turned upside down.

10はほぼ垂直に打ち込むことができる。Next, a method of connecting the electric wire common groove will be described. First, the main bodies 1 and 1 are temporarily placed at the construction site, and the rubber packing 4 is applied to the end surface of one main body 1 and the rubber packing 4
The joint 6 is inserted into the concave portion 3 of the one main body 1 by penetrating the hole 6 of FIG. Then, as shown in the right side of FIG. 2, the connecting pin 10 is inserted from the upper surface of the main body 1 (here, the main body 1 on the right side), and the vertical hole 9 of the jointer 7 is passed through to connect the connecting pin 10.
The tip 10a of 10 is driven in until it reaches the hole 12 on the lower surface. At this time, since the jointer 7 is in a state in which the force due to the elasticity of the rubber packing 4 is not applied, the connecting pin
10 can be driven almost vertically.

を打ち込んでもよい。Next, the opposite side of the jointer 7 is inserted into the recess 3 of the other main body 1 (here, the main body 1 on the left side), and similarly, the connecting pin 10 is inserted into the connecting pin insertion hole 8 on the upper surface of the main body 1. At this time, the left side main body 1 may be pushed to the left side a little due to the elasticity of the rubber packing 4, and the tip of the inserted connecting pin 10 is guided along the guide 11 of the vertical hole 9 of the jointer 7 of the main body 1. It is inserted with being inclined outward. The tip 10a of the connecting pin 10 is the main body 1
When the connecting pin 10 is further driven from the state of reaching the hole 12 on the lower surface of the, the tip 10a of the connecting pin 10 is guided by the inclined surface 13 toward the inside of the main body 1. As a result, the connecting pin 10 is shown in FIG.
Attempting to change from the state shown in to the vertical state, the point A of the jointer 7 is pushed inward toward the inside of the main body 1 with a strong force. At the same time, the main bodies 1 and 1 on both sides are strongly drawn, and a strong connection is made in a state where the rubber packing 4 is compressed. The vertical holes 9 of the jointer 7 and the holes 12 on the lower surface of the main body 1 are not provided with guides or slopes, and the pair of main bodies 1 and 1 are pressed from both sides to compress the rubber packing 4, and the connecting pin 10

Can be done easily. Further, since it suffices to drive the connecting pin 10 from the upper surface, each member can be temporarily placed in advance at the construction site, and the efficiency of the connection work can be improved also from this surface.
