Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a connecting device for connecting members, for example, a connecting device used for connecting adjacent concrete products or the like.

[0002]

[Prior art]

 For example, when laying concrete U-shaped grooves or concrete fume pipes that are quite heavy and weigh several tons per unit by connecting them in the longitudinal direction, the connection work of the concrete products is extremely important. Had to work. Conventionally, in this connection operation, as understood from FIG. 1, a concrete product to be connected is lifted by a crane and transferred to a position to be connected.

[0003] However, since it cannot be transported to a position to be connected accurately, accurate positioning and final fine adjustment are performed by using a bar or the like by a number of workers by using a bar or the like. This was done by pressing (see FIG. 2). Also, as shown in Fig. 4, when connecting concrete products 1 and 1 in the excavated trench, when attaching the connecting plate to the side surface, the excavation must be made with a clearance large enough to allow various metal fittings to be operated. I had to.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of a member connecting device according to the present invention will be described with reference to the drawings. In the drawing, reference numeral 1 indicates a concrete product to be connected. The concrete products 1 are connected to form a sewer, a water culvert or a U-shaped groove.

Here, concrete products are heavy, and each of them weighs many tons. Therefore, these connecting operations are also difficult operations. First, as shown in FIG. 1, a concrete product 1 to be connected is lifted by a crane 2 or the like and transported to a location to be connected.

Then, after lowering at a predetermined position, accurate positioning and fine adjustment are performed. At that time, the connecting device of the present invention is used. First, a first embodiment of the present invention will be described. Here, reference numeral 3 denotes a locking portion provided at the side end of the concrete product 1 (for example, see FIG. 13).

However, the locking portion 3 may be a locking hole or a locking projection. In this embodiment, the locking portion 3 is formed as a locking hole (for example, see FIG. 5). The locking portions 3 are provided at both ends of the concrete product 1 (see FIGS. 5 to 10).

Next, reference numeral 4 denotes a connecting member. The connecting member 4 includes an operating plate 5 having a substantially rectangular plate shape and a disk-shaped rotating plate 6. The working plate 5 is formed at one end thereof with a projecting engaging portion 7 to be inserted into the engaging portion 3 of the concrete product 1 (for example, see FIG. 14 in another embodiment).

Further, the other end of the operation plate 5 is connected to the rotation plate 6 with a pin, and the rotation plate 6 is rotatable around the pin connection portion 8 as a fulcrum. Further, a notch 9 for locking is provided on a side surface of the operation plate 5 near the pin connection portion 8. The use state of the connecting tool 4 will be described above. As shown in FIGS. 5 to 10, one side of the locking parts 3, 3 provided at the side end parts of the adjacent concrete products 1, 1. The engaging portion 7 of the operating plate 5 is fitted, and the projecting engaging portion 10 provided at the center of the rotating plate 6 is fitted on the other side.

In this state, the rotating plate 6 is rotated counterclockwise as viewed in the figure, and a projection-shaped engaging portion 10 provided at the center of the rotating plate 6 is used for locking the operation plate 5. Fit into notch 9. A series of movements is shown in FIGS. As a result, the adjacent concrete products 1, 1 are accurately positioned and connected.

Next, FIGS. 11 to 23 show a second embodiment of the present invention. The connecting tool of this embodiment includes a pair of operating plates 6 and 6 and a rotating plate 5 (see FIGS. 13 and 14). At one end of the pair of operation plates 6, 6, projection-like engaging portions 7, 7 are provided similarly to the operation plate 6. Further, the other end of the pair of operating plates 6 and 6 is pin-connected to the rotating plate 5, and the pair of operating plates 6 and 6 and the rotating plate 5 are rotatable around the pin connection portions 8 as fulcrums. By rotating the rotating plate 5, the pair of operating plates 6 and 6 can be pulled and pushed out.

Further, FIGS. 13, 14 and 15 are views showing a side portion of the rotating plate 5, and a hollow portion 11 is formed on the side portion of the rotating plate 5 as described above. An operating rod 12 can be inserted into 11 (see FIGS. 11 and 12). By rotating the operating rod 12, the rotating plate 5 can be smoothly rotated even with a small force.

In the above, the use state of this embodiment will be described. As can be understood from FIG. 13, first, the locking portions 3, 3 provided at the side end portions of the adjacent concrete products 1, 1 are attached. The projecting engagement portions 7, 7 of the pair of operation plates 5, 5 of the connecting tool 4 according to the present embodiment are inserted. From this state, the operating rod 12 fitted and attached to the side of the rotating plate 6 is rotated in the direction of the arrow shown in FIG.

Then, the pair of operating plates 5 and 5 are drawn, and thereby the adjacent concrete products 1 and 1 are also drawn. Finally, as shown in FIGS. 12 and 22, the concrete products 1, 1 to be connected are accurately positioned and connected. Next, a third embodiment of the present invention will be described.

The third embodiment of the present invention is characterized by the connection between the rotating plate 6 and the pair of operating plates 5 and 5. That is, a long hole 13 is formed in the rotating plate 6 as shown in FIGS. 24 to 28, and protruding pins 14, 14 from a pair of operation plates 5, 5 are formed in the long hole 13. It is slidably mounted in the inner longitudinal direction. Therefore, the other configuration is the same as that of the second embodiment, and the usage state is the same as that of the second embodiment.

FIG. 29 shows another embodiment of the operating rod 12 of the present invention. For example, when the locking portions 3 and 3 are provided on the front and back surfaces of the U-shaped groove, respectively, both the locking portions 3 and 3 are provided. It is also possible to adopt a configuration in which a connecting tool is fitted into the connecting rod, two operating rods 12, 12 are attached, and the two operating rods 12, 12 are integrated and connected by a connecting rod 15. According to such a configuration, positioning and connection can be performed quickly and accurately with a smaller force.

[0021]

[Effect of the invention]

 Thus, the present invention has the above configuration. With the member connecting device according to the present invention, it is possible to easily perform fine adjustment or accurate positioning of a concrete product to be connected, and to provide a member connecting device with extremely low product cost.

Further, it is possible to provide a connecting device that does not require excavation of a large area when connecting concrete products in the excavated groove.
