[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sealing material for holding a refractory material filled between an outer curtain wall and a floor slab.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 3 and 4, in order to fill a gap between an outer wall curtain wall 1 and a floor slab 2 with a refractory filler 3 and to close the outer wall curtain wall 1 after placing slab concrete. Attach and support metal 4
(Wires, rebars, etc.) are drilled in the upper part of the concrete slab, or the support metal 4a (iron plate) is nailed to the concrete slab, and then the refractory material 5
(A lath, an iron plate, or the like) is engaged with the support metal 4 and attached, and then the refractory filler 3 is filled.

[0003]

However, the mounting of the support hardware 4 involves operations such as making holes in the concrete and welding, and the work efficiency is extremely low, which is troublesome. In addition, it is troublesome to cut and attach a lath, an iron plate, or the like, and the refractory filler 3
However, there is a problem that there is a risk of falling due to vibration or the like.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a plugging material which can easily arrange a support material of a refractory filler filled between an outer wall curtain wall and a floor slab. Aim.

[0005]

Means for Solving the Problems To solve the above problems of the present invention.
Means for making a concrete stopper plate provided as a side disposal mold at the outer peripheral end of the floor slab with a required gap with the outer wall of the building, and a taper with the gap with the outer wall narrowed at the lower part And bend it to the outer wall side after casting concrete under the concrete stopper plate.
It is formed by providing a cutting line for the bent piece for support .

[0006]

According to the present invention, the refractory filler filled in the gap between the outer wall by the curtain wall and the outer peripheral end of the floor slab by the sealing material between the outer walls on the floor surface has a taper formed by bending at a required angle. The concrete stopper plate is provided so that the taper is tapered as it goes downward, so that it does not fall.

Further , the concrete stopper plate is located on the side of the floor slab.
Supports separately prepared because it is also used as a discarded formwork for the surface
Eliminates the complexity of attaching cover material with hardware etc.
In addition to the production cost, as a sealing material between outer walls
Is also reduced. Since the supporting bent pieces have a required width and are provided at required intervals along the longitudinal direction of the concrete stopper plate, the refractory filler is reliably supported.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing one embodiment of a sealing material between outer walls on a floor surface according to the present invention.

Here, the structure of the sealing material between the outer walls on the floor surface is such that the metal concrete stopper plate 6 is provided with a taper having an acute angle θ so that the gap with the outer wall curtain wall 1 becomes narrower as going downward. Bend to

At the lower part of the concrete stopper plate 6, supporting bent pieces having a required width which are cut and raised on the outer wall curtain wall 1 side at a required interval along the longitudinal direction and bent substantially horizontally. 7 is provided.

As shown in FIG. 1, the support folding piece 7 is cut into a horseshoe-shaped cutting line 8 at the lower part of the concrete retaining plate 6 in advance at a factory, and as shown in FIG. After the concrete is cast, it is cut and raised along a fold line 9 (shown by a broken line in FIG. 1) toward the outer wall curtain wall 1 and further bent substantially horizontally.

[0012] To explain the use of the concrete stop plate 6 thus formed, the gap between the outer wall curtain wall 1 to the outer edge of the floor slab 2 so as to become narrower toward downward, said concrete retaining Plate 6 on floor
It is provided as a disposal mold for the side of the lab 2.

That is, a concrete stopper plate 6 is fixed to the end of the deck plate 10 as shown in FIG. 2, and concrete is cast on the deck plate 10 by casting in place.
The floor slab 2 provided with the concrete stopper plate 6 at the end is constructed.

Then, the outer wall curtain wall 1 is attached to the beam of the S building by bolting with high tension bolts or the like via a fastener and an insert or the like, and the outer wall curtain wall 1 is attached.

Next, the supporting bent pieces 7 of the concrete stopper plate 6 are cut and raised, and are bent substantially horizontally along the fold lines 9 to form supporting hardware.

As shown in FIG. 2, between the outer wall curtain wall 1 and the concrete stopper 6, the supporting bent piece 7 bent substantially horizontally is provided with a refractory receiving material such as a strip-shaped lath. 5 is placed and supported, and the refractory filler 3
And fill the required quantity.

In this way, the refractory filler 3 is supported by the supporting bent pieces 7 arranged at the required intervals, and the tapered portion of the concrete stopper plate 6 may drop due to vibration or the like. Absent.

The structure of the sealing material between the outer walls on the floor surface according to the present invention is as described above. However, the shape and width of the supporting bent piece 7 and the pitch of the interval are appropriately determined according to design reasons. It is set.

Further, as another embodiment, the deck plate 1
The concrete end plate 6 as an outer wall closing material may be formed integrally with the deck plate 10 by bending the end of the zero.

The bending angle θ of the concrete stopper plate 6
The present invention is not particularly limited and is a matter of design. Of course, not only when the floor slab is formed of the deck plate but also when it is formed of the half PC floor plate, the sealing material between the outer walls on the floor according to the present invention can be applied. It is.

[0021]

As described above, the sealing material between the outer walls on the floor surface according to the present invention is disposed as a side disposal form at the outer peripheral end of the floor slab with a required gap from the outer wall of the building. The concrete stopper plate is bent in a tapered shape in which the gap between the outer wall and the outer wall is narrowed at the lower portion, and is cut and raised on the outer wall side after concrete is poured into the lower portion of the concrete stopper plate.
Since the cutting line for the formed supporting bending piece was provided and formed, the concrete stopper plate was used as a discarding formwork for the side of the floor slab.
Bending pieces for support after casting concrete
Just bend it approximately horizontally to form the support material of the refractory filler.
After that, remove the plugging material with a separately prepared support hardware, etc.
The work complexity of attaching is eliminated, and work efficiency is improved.
Not only shortens the construction period, but also
This also reduces manufacturing costs.

Further, since the concrete stopper plate is bent in a tapered shape, a gap between the concrete stopper plate and the outer curtain wall is narrowed downward, so that the refractory filler does not drop due to the vibration of the building, and the reliability is improved. It has an excellent effect of improving.
