DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a beam concrete jointing formwork in a building having a reinforced concrete structure.

[0002]

2. Description of the Related Art When beam concrete is spliced, it is necessary to partition the beam formwork at this splicing portion, and conventionally plywood or the like has been used as a partition plate.

[0003]

As is well known in the beam form, since a beam main bar is provided in the beam length direction, the partition plate also has a through hole through which the beam main bar is passed.

Since it is impossible to set this partition plate after arranging the reinforcing bars, at the same time when the reinforcing bars are assembled, the reinforcing bars are penetrated through the partition plates, and the reinforcing bars are arranged in the mold together with the reinforcing bars. This is an extremely troublesome task.

The object of the present invention is to eliminate the disadvantages of the above-mentioned conventional example, to enable the partition for concrete splicing to be formed easily and quickly even after the re-arrangement, and to easily remove the mold. The purpose is to provide an economical beam concrete connection formwork that can be diverted.

[0006]

In order to achieve the above-mentioned object, the present invention firstly introduces a metal plate having a notch into which a rebar is inserted into a side portion thereof into the notch, and , A plurality of plate bodies are arranged so as to sandwich the reinforcing bars between the plate bodies to partition the inside of the beam form, and the metal plate body is provided with a bar, and the protruding portion of the bar above is used as a handle. Or, in addition to this structure, a reinforcing bone extending laterally from the bar is provided. Second, a metal plate body having a notch for inserting the reinforcing bar on the side is provided in the notch of the reinforcing bar. This is a flexible packing with a plurality of plates arranged side by side so as to sandwich the reinforcing bars between the plates and partitioning the inside of the beam form, and a reinforcing bar insertion hole and a cutting line from this insertion hole to the outer edge. Place the body along the one side of the sandwiched part of the reinforcing bar between the plates. The one in which the subject matter of the present invention.

[0007]

According to the first aspect of the present invention, the partition for concrete splicing is formed by arranging a plurality of plates, and the plates are inserted between the formwork and the reinforcing bars and between the reinforcing bars to cut the reinforcing bars. It suffices if the reinforcing bars are inserted into the notches and the reinforcing bars are sandwiched between the plates, so that the partition can be easily formed in the mold even after the reinforcing bars are arranged.

Since the bar serves as a reinforcing member and the protruding portion upward is used as a handle, the bar is inserted between the plate form frame and the reinforcing bars and between the reinforcing bars, and rotated to rotate the reinforcing bars into the notches. The reinforcing bars can be inserted and the reinforcing bars can be sandwiched between the plates.

According to the second aspect of the present invention, in addition to the above-mentioned action, by providing a reinforcing bone in addition to the bar, vertical and horizontal reinforcement can be obtained, and even if the notch for adjustment has a large horizontal length. As a plate, it does not lose its robustness.

According to the third aspect of the present invention, when the reinforcing bars are sandwiched between the plate bodies, there is a spillage of concrete or the like, but there is a spillage of concrete. Can be prevented.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a front view showing an embodiment of a beam concrete splicing formwork of the present invention, FIG. 2 is a plan view of the same, and FIG.

Explaining the member construction first, the beam concrete connecting frame of the present invention is a plate body made of steel plates as many as between the beam frame 1 and the beam main bar 2 or the beam main bars 2 arranged side by side. Consists of. In this embodiment, there are five plates 3a to 3e.

The plates 3a and 3e, 3b and 3d are bilaterally symmetrical, and although the plates 3e and 3d are not shown in FIG. 4, the plates 3a are attached to the form 1 and the beam main bar 2. As an arrangement, a relatively short notch 4a into which the main beam 2 of the beam is inserted is formed on one side only in the upper and lower steps. Plate 3e
The same is true for

The plate body 3b is arranged between the beam main bars 2 and has a relatively long notch 4b on one side, which corresponds to the notch 4a of the plate body 3a, into which the beam main bar 2 is inserted. Then, a short notch 4a is formed on the other side in the upper and lower stages. The same applies to the plate body 3d.

The plate body 3c is also disposed between the beam main bars 2 and has a relatively short notch 4 into which the beam main bars 2 are inserted.
a was formed in the upper and lower stages on the side.

In each of these plate bodies 3a to 3e, a bar 5 made of an angle member is arranged in the vertical direction to serve as a reinforcing member, and a protruding portion of the bar 5 above serves as a handle 6. Further, a grip portion 6a, which is also made of an angle member, is provided at the upper end of the handle 6 in the orthogonal direction to form a T-shape as a whole.

The plate members 3b, 3d and the plate member 3c are also provided with reinforcing members by angle members in the orthogonal direction at the lower end of the bar 5, but in the plate members 3b, 3d, the angle member is provided near the relatively long notch 4b. Due to this, a reinforcing bone 7 extending laterally from the bar 5 is provided.

The plates 3a to 3e have the bar 5 as described above.
Although the surface on which the reinforcement bone 7 is not provided is a joint surface with the cast concrete, a striped steel plate or the like may be used to make the joint surface side a rough surface having irregularities, although not shown.

In the illustrated example, the beam main bar 2 is a screw bar reinforcement, and the nut 8 and the coupler 13 are screwed together for connection. However, the plate bodies 3a to 3e are individually formed in the beam form frame 1, It is inserted between the beam formwork 1 and the beam main bar 2 or between the beam main bars 2.

In this case, the plate bodies 3a to 3e are preferably inserted by holding the grips 6 in a direction parallel to the main beam 2 of the beam, and by rotating this, the main bar 2 of the beam is inserted into the notches 4a and 4b. In particular, the long cutouts 4b of the plates 3b and 3d are for adjusting the position with respect to the main beam 2 of the beam, and by changing the degree to which the plate 3b and the adjacent plate overlap, the five plates 3a-
3e are arranged in a line to partition the main beam 2 of the beam.

FIG. 5 shows a flexible packing body 9 made of a rubber plate or the like. A reinforcing bar insertion hole 10 is provided at the center, and a cutting line 11 extending from the insertion hole 10 to the outer edge is provided.

While opening the insertion hole 10 from the cutting line 11, the beam main reinforcement 2 is taken into the insertion hole 10 and the packing body 9 is applied to the beam main reinforcement 2 between the plate bodies 3a to 3e.
Place it along one side of the sandwiched part.

The plate bodies 3a to 3e are arranged so that the nut 8 is arranged on the side opposite to the concrete pouring side and the nut 8 is pressed by the nut 8.

When the concrete 12 is placed in the beam form 1 in this way, the concrete 12 is converted into the plates 3a to 3a.
Also, the packing body 9 stops the leakage of concrete from the notches 4a and 4b.

After the concrete 12 is hardened, the plate bodies 3a to 3e and the packing body 9 are removed and the concrete is spliced to the other parts.
When a striped steel plate or the like is used for a to 3e and the joint surface side of the concrete is roughened with irregularities, the joint surface also becomes irregular, and the joint state between the concrete is improved.

[0026]

As described above, the beam concrete connecting frame of the present invention can easily and quickly form the partition for concrete connecting even after the bar arrangement.
Moreover, it is economical because it can be easily removed from the mold and can be diverted.
