が増えつつある。As shown in FIG. 7, a lateral slit 85 is formed between the lower side of the outer wall 80 and the upper surface of the beam 90 (the concrete top 91: the upper surface of the floor slab). A vertical slit 87 is formed over the entire area between the outer wall 80 and the columns 70, 70. The upper side of the outer wall 80 is joined to a beam 90 on the upper floor. In recent years, demand has been increasing as a non-bearing wall which is a hanging wall having slits formed on three sides of the outer wall 80 as viewed from the front and does not affect the structural skeleton.

A horizontal slit height S10, which is a relatively large gap, is formed between the upper surface of the beam 90 and the flat portion 82 opposed thereto,
This height S10 substantially matches the height of the protruding portion 83.
Usually, the width T13 of the protrusion 83 is about 20 mm and the height is 2

るかといった施工上の問題等を生じる。In the above-described conventional horizontal slit structure of the outer wall 80, a projecting portion 83 downward from the flat portion 82 is formed at the bottom of the outer wall 80 at the end on the outdoor side. The width T13 of the portion 83 may be about 20 mm and the height may be about 25 mm, and thus there is a problem that a defective portion of the concrete or breakage is likely to occur.
That is, as shown in FIG. 9, since the protruding portion 83 is vulnerable to external force such as a horizontal force, cracks or defects are likely to occur at the corners between the protruding portion 83 and the flat surface 82 (see FIG. 9). Damage assumed surface is displayed). There is a possibility that the tile of the exterior material may fall off due to the loss or crack of the protruding portion 83. In addition, the horizontal slit 85 becomes a linear indoor / outdoor communication path having a large gap, causing intrusion of rainwater and outside air, lowering indoor / outdoor insulation, and deteriorating indoor habitability.
If the projection 83 is not provided, there is no problem such as breakage, but it is difficult to secure water stoppage, and there are problems in construction such as where to place the joint bar.

保持し易い。The slit height S2 below the intermediate step 12 is:
In consideration of the performance, material and thickness of the slit holding material, make sure that the outer wall 10 does not restrict the deformation of the rigid frame to the behavior of the building during the earthquake and adversely affect the behavior of the building and the type of failure. It is set to a size that can be handled. The slit height S2 is determined by the distance between the intermediate step 12 and the beam 2 at the time of placing concrete (at the time of construction), at the time of a normal vertical load, and at the time of an earthquake.
0 vertical deformation (shrinkage), material of slit holding material,
Set in consideration of strength. For example, the slit height S2
Is about 2 to 10 mm, preferably about 6 mm, but is not limited to this. Although the slit height S2 is smaller than the slit height S of the inner step portion 11, it is general that the slit height S2 is large enough to prevent the vertical force from being transmitted from the intermediate step portion 12 to the beam 20 via the slit holding member. . However, the slit height S2 may be reduced to allow a slight vertical force to be transmitted from the intermediate step 12 to the beam 20 via the slit holding member. Even when the upper surface of the beam 20 receives a vertical force, the pressure receiving area of the intermediate step portion 12 is small.
The frictional force acting between the upper surface of the beam 20 and the intermediate step 12 is small. Therefore, it is easy to maintain a slit function (sliding ability) between the beam 20 and the outer wall 10 against an in-plane horizontal force.

It is divided by the bottom of the outer wall 10 in which the intermediate step 12 and the outer step 13 are formed in a stepwise manner, and the upper side of a straight beam 20 in which a concave portion 21 is cut out at a corner on the outdoor side. I have. The shape of the outer wall of the lateral slit 30 in the thickness direction has the following characteristics. Slit height (S
2) is smaller than the slit height (S) of the inner step portion 11 and the slit height (height of the concave portion 21) of the outer step portion 13 to form a narrow gap (S2). A communication path connecting the inside and the outside passing through the center of the height of the horizontal slit 30 is bent and formed in a three-step shape.

In addition, rainwater, noise, outside air, and the like hardly enter the indoors from the outdoor side, thereby increasing the indoor habitability. That is, the insulation between indoors and outdoors is significantly improved.

Nevertheless, the length of the outer step 13 projecting downward can be greatly reduced. That is, as shown in FIG. 3, an intermediate step 12 facing the upper surface of the beam 20 is provided between the inner step 11 and the outer step 13 at the bottom of the outer wall 10 to form a three-step structure. The stress burden on the outer step 13 is greatly reduced, and it is possible to prevent the corner formed by the outer step 13 and the intermediate step 12 from cracking or chipping.

Since it is formed, the communication path inside and outside the room is narrowed, the water stoppage is improved, and water leakage can be prevented. Also, the sound insulation performance is improved.

ことができる。Next, the steady rest member 40 will be described (see FIG. 4). The steadying member 40 has both ends embedded in the outer wall 10 and the beam 20, respectively.
Connect with 0. The anti-sway member 40 is attached to the outer wall 1 during an earthquake.
0 and the beam 20 have a soft rigidity that follows the displacement of the horizontal deformation in the in-plane direction between the outer wall 10 and the outer wall 10 against the horizontal force (seismic force, wind pressure) acting in the out-of-plane direction of the outer wall 10. The movement (run-out) of the out-of-plane direction 10 is regulated to some extent.
In this example, the steady member 40 having the entire length R has a lower side 40 b embedded and fixed inside the beam 20 and an upper side 40 b.
a is embedded and fixed inside the outer wall 10, and inside the outer wall 10, a flexible region R having a predetermined length from the bottom surface of the outer wall 10.
2 and a fixed region R1 connected to this and reaching the upper end. Therefore, as shown in FIG. 4, when a horizontal force in an out-of-plane direction is received from outside, the steady rest member 40 can be bent in the flexible region R2. Thereby, even if the slit height S2 is small, the horizontal slit 30 can follow the movement of the outer wall 10 during an earthquake in the in-plane direction, suppresses excessive horizontal deformation in the out-of-plane direction, and damage the outer wall 10. Can be prevented.

The flexible region is formed by positioning a hollow tube in which a space is formed around the steady rest member 40, or by positioning a flexible member (tube or the like) such as a synthetic resin foam around the steady rest member 40. R2 can be formed. The material of the steady rest member 40 is not particularly limited, but, for example, a steel bar subjected to a rust-proof treatment is preferably used. It may be made of metal (iron, aluminum, stainless steel, etc.) excellent in rust prevention, synthetic resin, or the like. The flexible region of the steady rest member 40 can also be provided inside the beam 20. The flexible region may be provided only inside the beam 20.

所設置されている。A horizontal slit 30 is formed between the lower side of the outer wall 10 and the upper surface of the beam 20 (concrete top: the upper surface of the floor slab 25). A vertical slit 87 is formed over the entire area between the vertical slits 70 and 70. The upper side of the outer wall 10 is integrally joined to the beam 20 on the upper floor. Since slits are formed on three sides of the outer wall 10 when viewed from the front, the outer wall 10 is a hanging wall (non-bearing wall) suspended from the beam 20 on the upper floor. Therefore, since the rigid frame composed of columns and beams and the outer wall which is a non-bearing wall are structurally separated, the outer wall 10 does not restrict horizontal deformation of the rigid frame during an earthquake. The vertical slit 87 may have a horizontal planar shape formed in a straight line having a predetermined horizontal width (Bs), similarly to the related art. The width (Bs) of the vertical slit 87 is set so that the column does not contact the outer wall during an earthquake (for example, the horizontal deformation angle is 1/100). A plurality of steady rest members 40 are provided at appropriate intervals in the span direction of the beam 20.
