Description

[Detailed description of the invention]

[0001]

The present invention is mainly used for connecting and supporting a formwork for forming a concrete casting space between the omnia board and the reinforcing steel bar of an omnia board which also serves as a wall formwork. , A joint between a reinforcing bar and a formwork.

[0002]

2. Description of the Related Art When an omnia board and a general formwork are used to form a concrete casting space for building a concrete wall, a reinforcing steel bar for an anchor projecting inside the omnia board is used. The formwork must be connected and supported. In this case, a fastener that can be fitted and locked to the rebar is used together, and one end of the separator is screwed into a screw hole provided in the fastener, and the other end of the separator is screwed. The formwork is joined to the part in a conventionally known manner.

A connecting member of this type is provided with a spring member for pressing the reinforcing bar, and the connecting member is fixed to the reinforcing bar by the pressing force of the spring member against the reinforcing bar. However, since the thin spring wire is used, the fixing force to the reinforcing bar is weak, and there is a possibility that the coupling tool may drop unexpectedly before connecting the mold and the coupling tool via the separator. Also, the installation of the spring wire was not easy.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIG. 1, reference numeral 1 denotes a gate-shaped main body, and both side plate portions 3a and 3b and a ceiling plate portion 6 are provided. The side plates 3a and 3b are formed in a U-shape in a side view by concave portions 4a and 4b cut from front sides thereof. Further, the recessed portions 4a and 4b of the both side plate portions 3a and 3b are formed with a reinforcing bar fitting concave portion 5 at the lower end of the lower side, and the ceiling plate portion 6 is formed with the reinforcing bar fitting concave portion 5 in a side view. A through screw hole 7 for coupling the separator is provided directly above.

Reference numeral 2 denotes a leaf spring, which connects the front end of the main body ceiling plate 6 between horizontal plate portions 8a and 8b abutting on the inner front and rear ends of the main body ceiling plate 6 and the front horizontal plate 8a. A folded plate portion 9 sandwiched from above and below, a rising portion 10 for retaining which is bent upward from the rear horizontal portion 8b, and a bent portion 5 which is bent and projected downward between the two horizontal plate portions 8a and 8b.
And a horizontal pressing portion 11 located immediately above the horizontal pressing portion.

The leaf spring 2 is provided with a rising portion 10 for retaining.
Moves under the ceiling plate 6 so that the ceiling plate 9 moves.
Of the main body ceiling plate portion 6 between the front horizontal plate portion 8a and the folded plate portion 9 by press-fitting the front end portion of the main body ceiling plate portion 6 from the front end side of the front plate portion 3a, 3b.
0 protrudes outside the rear end of the main body ceiling plate 6. The leaf spring 2 attached to the main body 1 in this manner is not pressed and moved along the main body ceiling plate portion 6 in a state opposite to that at the time of mounting along the main body ceiling plate portion 6 in a state where the retaining rising portion 10 is pressed down against elasticity. As long as it does not come off from the main body 1 unexpectedly.

[0008] The coupler configured as described above can be used as follows. That is, as shown in FIG. 2, a predetermined length of the separator 1 is inserted into the through screw hole 7 of the main body 1.
2, the main body 1 in a state where the one end screw portion 12a is screwed and connected.
Both side plate portions 3 are provided at predetermined positions of anchor reinforcing bars 15 projecting from the inside of the omnia board 13 via supporting reinforcing bars 14.
The rebar 15 is fitted so as to fit into the recessed portions 4a, 4b of the a, 3b. At this time, the horizontal pressing portion 11 of the leaf spring 2 is pressed toward the main body ceiling plate portion 6 by the reinforcing bar 15 to be elastically deformed, and the reinforcing bar 15 is fitted into the reinforcing bar fitting recess 5 of the both side plate portions 3a, 3b. Will forgive. Thus, the reinforcing bar 15 fitted into the reinforcing bar fitting recess 5 is pressed by the horizontal pressing portion 11 toward the reinforcing bar fitting recess 5 by the elastic return force of the leaf spring 2, and as a result, the main body 1 is Will be fixed.

When the fastener is mounted on the reinforcing bar 15, the separator 12 is rotated so that the interval between the form receiving plate spring 16 mounted on the separator 12 and the omnia plate 13 becomes a predetermined value. Then, the separator 12 is moved in and out of the main body 1 in the axial direction. Next, the separator 1 is inserted into the separator through hole 18 provided in the mold 17.
2 is inserted through the other end screw shaft portion 12b of the separator 12 and the other end screw shaft portion 12b of the separator 12 protruding outside the formwork 17 is screwed and connected with the formwork fastening body 19, and the formwork fastening body Using the main body 19, the mold 17 is fixed by a conventionally known method.

[0010]

[Operation and effect of the present invention] As described above, the coupling device of the present invention can be easily mounted simply by fitting the main body to the reinforcing steel bar of the omnia board, and the through-screw for the separator coupling provided in the main body. It is possible to connect and support the formwork to the rebar through a separator connected using holes, but in particular, according to the coupler of the present invention, the main body is fixed to the rebar by the pressing force of a leaf spring. The horizontal pressing portion between the horizontal plate portions at both ends of the leaf spring which is in contact with the inner side surface of the main body ceiling plate portion presses against the rebar. The rebar can be strongly and stably pressed and fixed by the portion (horizontal pressing portion).

Further, the leaf spring can be easily and easily attached to a predetermined position of the main body only by being fitted along the ceiling plate of the main body, so that the cost can be reduced.
