DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage structure provided with a grating and formed between two frames facing each other with a gap therebetween.

[0002]

2. Description of the Related Art A building is sometimes provided with an edge cut off in the middle of the building for the purpose of extension or seismic design. Between adjacent buildings with cut edges, skeletons face each other with a gap.
It is conventional to provide a grating or a drain in such a gap. However, in the known structure, since the drainage channel is configured by using the gap itself, when the relative displacement occurs between the frames due to an earthquake or the like, the gap is fluctuated and the drainage channel is likely to fail. There was a risk of drainage leakage. Also, the structure itself was complicated.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a drainage structure between skeletons which is less likely to fail even when relative displacement occurs between the skeletons and has a simple structure.

[0004]

According to the present invention, there is provided a drainage structure between skeletons, wherein the drainage structure is formed between the first and second frames facing each other with a gap therebetween. A drain groove is formed along the gap, and the grating is placed over the gap and the drain groove and over both frames. In the second frame, a draining material is fixed below the grating. The drainer has an inclined plate portion which is inclined to be lower toward the first frame side below the grating and extends to above the drain groove. It is characterized by being slidably supported by the first frame.

[0005]

The drainage such as rainwater that has fallen through the grating falls directly into the drain, or falls on the inclined plate of the drainer, flows on the inclined plate, and falls into the drain. When relative displacement occurs between the frames, the inclined plate portion moves relative to the first frame, the displacement is absorbed, and no failure occurs.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a longitudinal sectional view showing a drainage structure of the present invention. 2
The two skeletons 1a and 1b face each other with a gap 2 therebetween. The skeletons 1a and 1b are formed by stacking base layers 12a and 12b made of cinders and the like, lower layers 13a and 13b made of concrete, and surface layers 14a and 14b made of tiles and stones on main bodies 11a and 11b made of slabs. ing.

A drain groove 3 is formed along the gap 2 at the edge of the base layer 12a of the frame 1a on the gap 2 side. The drain 3 communicates with a drain pipe (not shown). The drainage groove 3 is formed of a three-layered vertical cross-section concave wall including a steel rim 31a, a waterproof layer 32a, and a mortar layer 33a. 3
4a is an asphalt caulking layer. The rim member 31a is fixed to the main body 11a with an anchor bolt 35a.

A mortar layer 33b is provided at an edge of the base layer 12b of the frame 1b on the gap 2 side, separated by a waterproof layer 32b. 34b is an asphalt caulking layer. In the portion of the mortar layer 33b facing the gap 2, an edge material 3 is provided.
1b is provided fixed to the angle 36b. The angle 36b is fixed to the main body 11b with an anchor bolt 35b. The rim member 31b includes a vertical plate portion 311b and a horizontal plate portion 312b.

At the end of the lower layer 13a above the mortar layer 33a of the drain groove 3, a frame 4a is provided fixed to an angle 36a. The frame 4a has a vertical plate portion 41a.
And a horizontal plate portion 42a. On the other hand, above the horizontal plate portion 312b of the edge material 31b of the frame 1b,
Is provided. The drainer 4b includes a vertical plate portion 41b and an inclined plate portion 42b. Then, the grating 5 has one edge portion of the horizontal plate portion 42a of the frame 4a.
It is placed on the inclined plate portion 42b of the drainer 4b via the plate-like elastic body 6b, and is placed on the frame 1a, 1b. It is provided to pass. That is, the grating 5 is provided between the frames 1a and 1b so as to cover the gap 2 and the drain groove 3. Packings 7a and 7b are sandwiched between the grating 5 and the vertical plate portion 41a of the frame 4a, and between the grating 5 and the vertical plate portion 41b of the drainer 4b, respectively.

The draining member 4b is provided on the horizontal plate portion 3 of the edge member 31b.
The sloping plate portion 42b is fixed to the upper surface of the steel tubular body 8 having a rectangular vertical section fixed to the upper surface of the rim member 31b.
Consequently, it is fixed to the frame 1b. The cylindrical body 8 is configured by fitting a U-shaped frame from above and below.

The inclined plate portion 42b of the drainer 4b is
a, and gradually lowers toward
And extends to above the drain ditch 3. Inclined plate 42
b is an edge material 31 facing the gap 2 on the side of the frame 1a.
cylindrical packing 9 fixed to upper end horizontal portion 311a
Is slidably supported from below. Inclined plate part 42b
Has a downward extension 421b at its tip. Also, the inclined plate portion 42b has reinforcing ribs 422b extending at right angles at appropriate intervals.

According to the drainage structure having the above-mentioned structure, drainage such as rainwater that has fallen through the grating 5 directly falls into the drain groove 3 or falls onto the inclined plate portion 42b of the drainer 4b to be inclined. After flowing on the portion 42b, it flows down the lower edge 421b and falls into the drain groove 3. That is, the drainage does not fall into the gap 2 at all.

When a relative displacement occurs between the frames 1a and 1b due to an earthquake or the like, the inclined plate 42b is slidably supported by the packing 9, so that the inclined plate 42b moves relative to the frame 1a. Only the relative movement is performed as indicated by the arrow in the figure, and the above-described drainage is performed without any trouble. That is,
Even if a relative displacement occurs between the skeletons 1a and 1b, the drainage structure having the above configuration does not break down.

Further, the drainage structure having the above-described structure is characterized in that the inclined plate portion 4
Since only the draining member 4b having 2b and the drain groove 3 are used as main components, the structure is simple, and from this point, a failure is unlikely to occur.

[0015]

As described above, the drainage structure between frames according to the present invention has the following effects. (1) Drainage such as rainwater that has passed through the grating 5 can be directly collected into the drain groove 3 or drained along the inclined plate portion 42b of the drainer 4b and transmitted along the lower edge portion 421b. It can be dropped into the groove 3 and collected. That is, the drainage can be collected and drained in the drainage groove 3 without flowing into the gap 2 at all.

(2) Since the inclined plate portion 42b of the drainer 4b is slidably supported by the packing 9, even if a relative displacement occurs between the frames 1a and 1b, the inclined plate portion 42b
Can be moved relative to the frame 1a to absorb the displacement,
Drainage can be reliably performed without causing a failure.

(3) Drainer 4 having inclined plate portion 42b
b and the drain 3 are the only main components,
The structure is simple, and failure is unlikely to occur from this point as well.
