[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an expansion joint structure provided between both frames of a high-rise building and a low-rise building.

[0002]

2. Description of the Related Art Hitherto, there has been no suitable expansion joint structure provided between a high-rise building and a low-rise building.

[0003]

Therefore, in the past, when a high-rise building and a low-rise building relatively vibrated due to an earthquake or a typhoon, the connecting portion of the building might be destroyed.

[0004] The rain water that falls along the outer wall of the high-rise building is bad, especially at the above-mentioned connecting portion with the low-rise building, and water may enter the inside of the building body. was there.

Therefore, the present invention solves the above-mentioned conventional problems and can smoothly adapt to the change between the frames of both buildings.
It is an object of the present invention to provide an expansion joint structure that improves the rain water falling down the outer wall of a high-rise building.

[0006]

In order to achieve the above object, the present invention provides a lower end surface of a vertical PC board attached to a first body and an inclined draining board attached to a second body. In the expansion joint structure, which is interposed between the PC board and the lower end surface of the PC board, an interposition member made of a metal shape member having a plurality of vacant spaces is attached to the back surface side of the PC board. It is held between the draining plate and the sealing member between the interposing member and the lower end surface, and a horizontal plane is relatively provided between the interposing member and the draining plate. It is provided with a sealing material that allows the inside to move.

[0007]

In the expansion joint structure constructed as described above, the interposing member and the draining plate are relatively movable in the horizontal plane by interposing the sealing material between the interposing member and the draining plate.

Further, even if rainwater falls along the outer wall of the vertical PC board, the sealing material can prevent the infiltration of the rainwater, and even if the water invades from the sealing material due to heavy rain such as a typhoon. The force of rainwater entering can be weakened by the plurality of vacant spaces.

As shown in FIG. 2, the expansion joint structure is divided into vacant chambers 75 and 76 by the vertical PC plate 1, the interposition member 3, the draining plate 2 and the like.

Next, as shown in FIG. 5, in the space D between the two bodies A and B, a thin water stop plate 70 made of plastic or the like,
A refractory zone 71 is interposed to block the gap D to form a refractory structure.

On the edge member 49 attached to the second body B, the side edges of the water stop plate 70 and the fireproof zone 71 are integrally attached by rivets or the like, and are provided on the first body A. Metal wall material
Only the water stop plate 70 is attached to the edge member 72 fixed to the 74 with rivets or the like, and the fireproof zone 71 is attached to the wall member 74 together with the edge member 73 in a state separated from the water stop plate 70. .

This water stop plate 70 has a length of an appropriate interval,
It is formed so as to have a gradient in the longitudinal direction, and when connecting the water blocking plates 70 in the longitudinal direction, the ends of each water blocking plate 70 are overlapped and connected, and the gap is sealed with putty or the like.

As described above, in order to improve workability when connecting the water blocking plate 70, the water blocking plate 70 and the fireproof zone 71 are separately attached to the wall material 74 in a separated state. .

Therefore, in the expansion joint structure constructed as described above, as shown in FIG. 2, the seal members 7a and 7b are interposed between the interposing member 3 and the draining plate 2 so that the arrow E As described above, the interposition member 3 and the draining plate 2 are relatively movable in the horizontal plane.

Even if the interposition member 3 and the draining plate 2 move relative to each other in the horizontal plane, the elastic contact portions 45, 65 of the seal members 7a, 7b move to the draining plate 2 and the horizontal contact piece 23. While keeping the contact state, it is possible to follow the fluctuation by elastic deformation and prevent the intrusion of rainwater.

Further, even if the two bodies A and B are relatively displaced in the vertical direction, the sealing material 6 interposed between the lower end surface 5 of the vertical PC board 1 and the interposing member 3, and the above-mentioned seal. By material 7,
Rainwater can be prevented from invading by following the fluctuation in the contact state.

Further, even if rainwater falls along the outer wall of the vertical PC board 1, the seal materials 6a and 7a can prevent the rainwater from entering, and the rainwater can be prevented by the heavy rain such as a typhoon. Even if it intrudes into the inside, the force of rainwater infiltration can be weakened by the plurality of vacant chamber portions 76, 32, 26, 75, and rainwater does not easily infiltrate between the two bodies A and B.

Then, when it enters the inside of each vacant chamber 76, 32,
The water collected in 26 and 75 passes through the drain holes 44 and 64, and the sealing material 7
The water can be drained from between a and the draining plate 2, and the water falling along the groove 13 (see FIG. 3) of the vertical PC plate 1 can also be drained similarly.

The present invention is not limited to the above-mentioned embodiment, and the design can be freely changed without departing from the gist of the present invention.

For example, the number of drainage holes 44 and 64 can be increased or decreased and the positions can be changed freely.

Further, as the sealing material 6, two sealing materials 6a and 6b are illustrated in the illustrated example, but the number may be three or more, and the sealing material 7 may be three in the illustrated example. Although the individual sealing materials 7a, 7b, 7b are used, it is also possible to use two or four sealing materials.

[0055]

Since the present invention is constructed as described above, it has the following great effects.

When the clearance between the two bodies A and B changes due to an earthquake or the like, it is possible to adapt smoothly.

Further, the rain water falling down from the outer wall of the vertical PC board 1 can be well treated.
