Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an interior wall which stands independently of a column or wall supporting a load in a building, and is particularly suitably used for a building having a large interlayer deformation. TECHNICAL FIELD The present invention relates to an interior wall body and a support metal fitting thereof.

[0002]

2. Description of the Related Art In a building such as a steel frame structure or a steel reinforced concrete structure, a structural body is often constructed of steel or concrete, and an exterior member made of concrete, a metal plate, or the like is often attached to the outside thereof. On the other hand, a panel-like wall is formed on the inner side, and this is fixed to a structural skeleton to provide an interior. In addition, most of the partition walls have a panel-like wall body that is similarly erected, and upper and lower ends thereof are fixed to a structural frame.

The above-mentioned panel-like interior wall is often formed by forming a frame from wood or lightweight steel and attaching an interior member such as decorative plywood or gypsum board. The body is generally fixed to the structural body at the upper and lower ends.
That is, it is firmly supported at the upper and lower ends so that the wall surface on the indoor side does not easily shake.

[0004]

However, the above-mentioned interior wall has the following problems. In multi-story buildings such as steel structures, to improve earthquake resistance,
A structure allowing a large interlayer deformation is often adopted. That is, even when a large earthquake occurs as a so-called flexible structure, a large shear force in the horizontal direction does not act on the structural skeleton. Also, in middle- and low-rise houses, etc., the demand for seismic resistance is high, so the relative displacement in the horizontal direction between the upper floor and the lower floor or the relative displacement between the floor and the roof structure The adoption of a structure that allows a large displacement is also increasing.

[0005] In a building that allows such large interlayer deformation, an interior wall having upper and lower ends fixed to the structural frame despite the fact that the structural frame maintains sufficient safety during an earthquake or the like. The body may not be able to follow the large interlayer deformation and may be damaged. In other words, the panel-like interior wall is hardly deformed in a direction parallel to the wall surface, and when interlayer deformation of the structural body occurs in this direction, the horizontal wall formed between the upper end and the lower end is not deformed. It is destroyed by shearing force. Further, in a portion where the partition wall or the like is joined at a right angle, the joined portion is easily broken.

The present invention has been made in view of the above problems, and has as its object to provide an interior wall body which is not damaged even when a large interlayer deformation occurs in a structural frame. I do.

[0007]

In order to solve the above-mentioned problems, an invention according to claim 1 is an interior wall body that is erected independently of a column or wall body that supports a load. It is an object of the present invention to provide an interior wall body in which a top is joined to a floor structure or a roof structure of an upper floor and a support metal that allows relative displacement at least in a horizontal direction parallel to a wall surface of the interior wall body.

[0008] The support fitting used in the interior wall is:
Various forms such as those having a locking portion slidable in the horizontal direction parallel to the wall or those deformable in the horizontal direction parallel to the wall can be adopted.
It is desirable to use one having a structure as described in (1). That is, it has a vertical plate portion which is made of a thin metal plate and is substantially vertical and is set up substantially perpendicularly to the wall surface of the interior wall.

According to a third aspect of the present invention, the vertical plate portion of the support fitting has a laterally protruding portion formed by being bent along a horizontal line. Things are desirable. The shape of this protrusion is triangular in cross section,
Various shapes such as an arc, a rectangle, or a combination thereof can be employed. Further, the number of protrusions is not limited to one, and a plurality of protrusions may be provided.

In the interior wall having the above-described structure, a relative displacement in the horizontal direction parallel to the wall of the wall is allowed between the top and the floor structure or the roof structure of the upper floor. Therefore, even if a large interlayer deformation occurs in the structural frame such as columns and walls supporting the load, no large deformation occurs in the interior wall, and the generation of a large force in the direction of the wall is avoided. The wall is prevented from being damaged. In the direction perpendicular to the wall surface, even if a relatively large deformation occurs in the wall body, the wall body is relatively easily deformed and is hardly damaged.

[0011] Further, as in the interior wall according to the second aspect, a vertical plate portion made of a thin metal plate is provided at the junction between the top of the interior wall and the floor structure or the roof structure of the upper floor. By using a support fitting in which the vertical plate portion is substantially perpendicular to the wall surface, the vertical plate portion is deformed, thereby permitting relative displacement in the horizontal direction. Further, the vertical plate portion has a large rigidity in a direction parallel to the vertical plane, and is not easily deformed. Therefore, the top of the interior wall body is firmly supported in a direction perpendicular to the wall surface, and the wall body does not easily shake even if some force acts from the living room.

Further, the above-mentioned vertical plate portion is formed with a laterally protruding portion bent along a horizontal line, so that deformation of this portion allows the interior wall and the structural skeleton to be formed. Large relative deformation is allowed during

The invention described in claim 4 is the same as the claim 2.
Alternatively, in the interior wall body according to claim 3, the support bracket is provided with a long hole having a major axis in a direction substantially perpendicular to the wall surface of the interior wall body at an upper portion thereof, and is inserted through the long hole. It is assumed that it is connected to the floor structure or the roof structure of the upper floor by bolts.

Such an interior wall has an elongated hole in a direction perpendicular to the wall surface, that is, in a direction parallel to the vertical plane of the vertical plate portion, and the supporting bracket is not easily deformed in this direction. However, it is possible to easily adjust and join the position of the support bracket and the structural skeleton by using the elongated holes. Further, when a large force acts in the long axis direction of the long hole, the position of the bolt is shifted within the range of the long hole, so that relative displacement in the direction perpendicular to the wall surface can be allowed.
Thereby, in a portion where the wall body cannot be deformed in a direction perpendicular to the wall surface, such as a portion where the interior wall is joined at a right angle, the horizontal phase displacement between the interior wall and the structural skeleton is reduced. It can be tolerated and prevent damage to the wall.

The invention according to claim 5 is used for joining the top of an interior wall erected independently of a pillar or wall supporting a load and a floor structure or a roof structure of an upper floor. An interior wall support bracket that is made of a thin metal plate, is set up almost vertically, and has a side projection formed by bending along a horizontal line. A vertical plate portion, a lower mounting portion which is continuous with a lower end of the vertical plate portion and is fixed to a main body portion of the interior wall, and which is continuous with an upper end of the vertical plate portion and which is substantially vertical to the vertical plate portion; The present invention provides an interior wall support bracket having a long hole having a long axis parallel to a flat surface, and having an upper mounting portion joined to the floor structure or the roof structure by a bolt inserted into the long hole. is there.

[0016] In such an interior wall support bracket, at the top of the interior wall standing upright independently of the structural skeleton,
A simple structure allows relative horizontal displacement with the structural body, and can be joined so as not to be easily shaken in a direction perpendicular to the interior wall.

On the floor surface, the main body 2 is erected independently of the pillars 11 and the exterior members 13, and is connected to the steel beams 12 supporting the upper floors via the support fittings 3. The lower end of the main body 2 is also fixed so as not to be displaced with respect to the floor slab 14.

As shown in FIG. 2, the main body 2 of the interior wall forms a frame with a plurality of studs 4 made of wood and a cross member 5 connecting the upper and lower ends thereof. An interior material such as decorative plywood (not shown) is attached to the inner surface.

The support bracket 3 is shown in FIG.
FIG. 4] and a side view [(b)], and FIG. 4 is a perspective view, which is manufactured by bending a steel plate material and is arranged substantially vertically when used. It has an upper mounting portion 32 formed by bending the upper portion at a substantially right angle, and a lower mounting portion 33 having a lower portion of the vertical plate portion 31 bent at a substantially right angle in a direction opposite to the upper mounting portion 32. ing. The vertical plate portion 31 has a protruding portion 31a formed so as to protrude laterally by being bent along three horizontal lines.

The support 3 is attached to the lower mounting portion 33.

Although the interior wall 1 shown in FIG. 1 is installed upright inside the exterior member 13 to provide interior, the partition wall 6 shown in FIG. 2 can have the same structure. The ceiling 15 is suspended from the steel beam 12 by a suspension member 16.

In such an interior wall, the support fitting 3 for connecting the top of the main body 2 to the steel beam 12 is formed by bending a steel plate material, and the vertical surface of the vertical plate portion 31 is formed. It is difficult to deform in the direction parallel to
The displacement in the direction perpendicular to the wall surface of the top portion of the main body 2 can be restrained, and it is supported so that it does not easily shake or tilt against a horizontal load from the indoor side.

Also, when a large interlayer deformation occurs during an earthquake, the main body 2 is hardly deformed in a direction parallel to the wall surface, and follows a large relative displacement between the lower floor and the upper floor. However, in the direction parallel to the wall surface, the vertical plate portion 31 of the support fitting 3 is easily deformed to absorb the relative displacement of the upper and lower floors. Therefore, a large force does not act on the panel-shaped main body 2, and the interior wall 1 is prevented from being damaged. On the other hand, when the upper and lower floors are displaced relative to each other in the direction perpendicular to the wall surface, the support fitting 3 is hardly deformed, but the wall body is not easily broken even if deformed in the direction perpendicular to the wall surface. .

However, at a portion where the two interior wall members are joined at a right angle, such as a joint portion between the interior wall member 1 and the partition wall 6 provided along the outer wall surface, the portion is perpendicular to the wall surface. The wall is not easily deformed in the direction. However, when a large force equal to or more than a predetermined value acts between the support member 3 and the steel beam 12 in such a portion, the position of the support member 3 is shifted within the range of the long hole 32a, and the wall of the interior wall is damaged. Damage can be reduced.
