BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a non-bearing wall made of reinforced concrete, which is constructed by cast-in-place reinforced concrete construction and mainly constitutes an outer wall such as a curtain wall.

[0002]

[Problems to be solved by the invention] When a finishing material such as a stone or a tile is used for decorating an outer wall of a building such as a panel of a curtain wall, the finishing material should be attached to a precast concrete slab with a fastener or mortar sandwiched between them. However, this precast concrete slab with a finishing material has a problem that the manufacturing cost is high.

Further, in the case of a precast concrete slab, it will be built in order from the lower floor side, but in general, the construction will often proceed without the detailed design of the first floor being decided, and the details have been built. It is necessary to consider it later.

The present invention was made by paying attention to the problems encountered when a finishing material is used for the outer wall surface, and is intended to newly propose a non-bearing wall having a structure that solves the problem.

[0005]

According to the present invention, the main body of the outer wall panel in the case of a curtain wall is composed of a non-bearing wall made of reinforced concrete, and the finishing material for decoration of the wall is separated from the non-bearing wall. It reduces the cost of integrating the finishing material with the wall and panelizing it, while eliminating the need to re-examine details after the precast concrete slab is built.

The non-bearing wall is made of cast-in-place reinforced concrete, and is cut up and down in the middle of its height to provide the same level of absorption of interlayer displacement as precast concrete slabs. The finishing material is simply supported by being separated from the non-bearing wall and attached to the outer peripheral side of the finishing material later.

The non-bearing wall is composed of a hanging wall which is connected to a beam on the upper floor and hangs down, and a standing wall which is separated from the floor of the lower floor and stands up with a gap provided between the hanging wall and the hanging wall. And a connecting plate spanned between the side surfaces of the connecting plate and a bolt that penetrates the connecting plate and is fixed to the hanging wall and the standing wall.

Either one of the bolt holes on the hanging wall side or the standing wall side of the connecting plate is opened in the shape of a long hole in the horizontal direction, both of which are movable relative to each other in the horizontal direction in the plane, and the standing wall is between layers. At the time of displacement, it moves relative to the drooping wall while being connected to the floor on the lower floor, just like a normal precast concrete slab.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings showing an embodiment.

The non-bearing wall W of the present invention is constructed by a cast-in-place reinforced concrete structure and constitutes an outer wall that does not bear a vertical load. As shown in FIGS.
A hanging wall W ₁ extending downward to connect to consist upright wall W ₂ Metropolitan rising disconnected from the floor S to the bottom floor, and connected both W _1, W ₂ and a relatively movable in a horizontal direction in a plane mutually It is a thing.

As shown in FIG. 1, the standing wall W ₂ is structurally separated from the floor S of the lower floor by being spliced at the lower end, but as shown in FIG. The connecting rebar 1 is embedded in the floor S on the lower floor so as to straddle the floor S, and the connecting rebar 1 is connected to the floor S on the lower floor in a state in which the movement is restricted. The joint material on the floor S side and the jointing surface of the standing wall W ₂ is filled with the sealing material 9.

The standing wall W ₂ is also insulated from the hanging wall W ₁ by a gap provided between the upper end of the standing wall W ₂ and the lower end of the hanging wall W ₁ , but with the hanging wall W ₁ its side surface as shown in FIG. They are connected by a connecting plate 2 spanned between them and supported by the hanging wall W ₁ . A cushioning material (10) such as polystyrene is inserted in the gap between the hanging wall (W ₁₎ and the standing wall (W ₂₎ in order to avoid collision during vertical displacement due to relative horizontal movement. Both sides of the cushioning material 10 are also filled with the sealing material 9.

As shown in FIG. 3, the standing wall W ₂ is divided into a length that allows relative movement with the hanging wall W ₁ during interlayer displacement, and has a size similar to that of the precast concrete slab. Therefore, each independent standing wall W ₂ is supported from the hanging wall W ₁ by an appropriate number of connecting plates 2.

[0014] coupling plate 2 therethrough as shown, to connect the hanging wall W ₁ and upstanding wall W ₂ by bolts 3 to be fixed to the respective hanging wall W ₁ and upright wall W _2. The connecting plate 2 is provided with ribs 2a, 2a on both sides for the purpose of stiffening the non-bearing wall W during interlayer displacement in the out-of-plane direction.

FIG. 4 is a partially enlarged view of FIG. 1 on each side surface of the hanging wall W ₁ and the standing wall W ₂ on the side where the connecting plate 2 is installed.
Bolts 3 buried plate 4 ₁ to the insert nut 5 is joined to is screwed, 4 ₂ are respectively embedded in the striking設時concrete as shown in. Each insert nut 5
Anchor bolt 6 is screwed and welded to the opposite side of bolt 3.

Bolt hole 2b on the side of the hanging wall W ₁ of the connecting plate 2
One of the bolt holes 2c on the upright wall W ₂ side is opened in the shape of a long hole that is long in the horizontal direction as shown in FIG. 5 showing the side surface of FIG.

Between the embedding plate 4 ₁ and the connecting plate 2 on the side of the bolt hole which is a long hole, in the case of the embodiment, on the side of the hanging wall W ₁ side of the bolt hole 2b, and between the connecting plate 2 and the washer 7 of the bolt 3. Low friction materials 8, 8 made of, for example, a stainless steel plate coated with graphite are sandwiched between and to reduce resistance during interlayer displacement.

In the case of the embodiment, since the washer 7 of the bolt 3 on the standing wall W ₂ side is welded to the connecting plate 2 so that the connecting plate 2 is fixed to the standing wall W ₂ , the non-bearing wall W.
At the time of interlayer displacement in the plane, the bolt 3 penetrating the bolt hole 2b on the side of the hanging wall W ₁ reciprocates along the bolt hole 2b, whereby the hanging wall W ₁ and the standing wall W ₂ relatively move in the horizontal direction. Then
Follow the displacement.

[0019] When pasting the stone on the outer surface wall as finishing material P non-bearing wall W, finishing material P is placed at a distance from the wall surface of the non-bearing wall W as shown in FIG. 1, the upright wall W ₂
And independently supported on the hanging wall W ₁ by fasteners 11,
Mortar 12 is filled between the non-bearing wall W.

Also in the case of tiles, the finishing material P is attached to the standing wall W ₂ and the hanging wall W ₁ independently by the mortar 12 as shown in FIG. When no gap is created between the non-bearing wall W and the non-bearing wall W, the connecting plate 2 is arranged on the opposite side of the finishing material P.

[0021]

The present invention is as described above. The non-bearing wall is made of cast-in-place reinforced concrete, and is insulated from the hanging wall and the standing wall in the middle of its height, precast concrete plate on the standing wall. It has the same level of absorption of inter-layer displacement, and when a finishing material is used, it can be supported by simply sticking it to this non-bearing wall, so the finishing material and precast concrete slab can be The manufacturing cost when integrated into a panel is reduced.

Further, in the case of the conventional precast concrete slab, although the construction usually proceeds from the lower floor side in spite of the progress of construction without the detailed design of the first floor being decided, in the present invention, the finishing material is Separated from non-bearing walls,
Since it is attached later, details can be dealt with later in the process.
