Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an interior wall that stands independently from a pillar or wall that supports a load in a building, and is particularly suitable for an interior wall that can be suitably used for a building having a large interlayer deformation. It is related with a body and its support metal fittings.
[0002]
[Prior art]
In a building such as a steel structure or a steel reinforced concrete structure, a structural frame 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. On the other hand, a panel-like wall body is formed on the inner side, and this is fixed to the structural housing to provide the interior. Further, many of the partition walls are similarly constructed by standing panel-like wall bodies and fixing the upper and lower ends to the structural housing.
[0003]
The panel-shaped interior wall body is formed of a frame body made of wood or lightweight steel frame, and is often used with an interior member such as a decorative plywood or gypsum board attached. Generally, it is fixed to the structural frame at the upper and lower ends. That is, it is firmly supported at the upper and lower ends so as not to easily shake as the wall surface on the indoor side.
[0004]
[Problems to be solved by the invention]
However, the wall for interior as described above has the following problems.
In multilayer buildings such as steel structures, in order to improve earthquake resistance, structures that allow large interlayer deformation are often employed. That is, even when a large earthquake occurs as a so-called flexible structure, a large horizontal shearing force does not act on the structural frame. In addition, the demand for seismic resistance is increasing in middle- and low-rise houses, etc., so the relative displacement in the horizontal direction between the upper floor and the lower floor or the relative relationship between the floor and the roof structure. The use of structures that allow a large amount of displacement is also increasing.
[0005]
In a building that allows such large inter-story deformation, the interior wall with the upper and lower ends fixed to the structural housing is large, even though the structural housing maintains sufficient safety during an earthquake. It is impossible to follow the interlayer deformation, resulting in damage. In other words, the panel-like interior wall body is less likely to be deformed in the direction parallel to the wall surface, and when the interlayer deformation of the structural housing occurs in this direction, the horizontal wall generated between the upper and lower ends It is destroyed by the shearing force. Further, at the portion where the partition walls and the like are joined at a right angle, the joined portion is easily broken.
[0006]
The present invention has been made in view of the above-described problems, and an object of the present invention is to provide an interior wall body that is not damaged even if a large interlayer deformation occurs in the structural housing.
[0007]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the invention according to claim 1 is an interior wall body standing upright independently of a pillar or wall body for supporting a load, wherein the top portion is a floor structure of an upper floor or Joined by a roof structure and a support metal fitting, the support metal fitting is made of a thin metal plate material, has a vertical plate portion that is substantially vertical and is erected substantially perpendicular to the wall surface of the interior wall body, and its lower end portion is The upper wall is fixed to the top of the main body forming the wall of the interior wall, and the upper end is fixed to the floor structure or roof structure of the upper floor, and the floor structure of the upper floor or It is an object of the present invention to provide an interior wall body in which relative displacement is allowed in a horizontal direction parallel to the wall surface of the interior wall body with respect to the roof structure .
[0008]
In addition, as described in claim 2, it is desirable that the vertical plate portion of the support bracket has a lateral protrusion formed by bending along a horizontal line. .
As the shape of the protruding portion, various shapes such as a triangular shape, an arc shape, a rectangular shape, or a shape obtained by combining these shapes can be adopted. Further, the number of protrusions is not limited to one, and a plurality of protrusions may be provided.
[0009]
In the interior wall body configured as described above, the relative displacement in the horizontal direction parallel to the wall surface of the wall body is allowed between the top portion and the floor structure or the roof structure of the upper floor. Even if a large inter-layer deformation occurs in the structural frame such as a column or wall that supports the load, the interior wall does not undergo a large deformation, and generation of a large force in the wall surface direction is avoided. Damage is prevented. In addition, even if a relatively large deformation occurs in the wall body in a direction perpendicular to the wall surface, the wall body is relatively easily deformed and is hardly damaged.
[0010]
The behavior of the interior wall body as described above has a vertical plate portion made of a metal thin plate material at the junction between the top portion of the interior wall body and the floor structure or the roof structure of the upper floor. This is realized by using a support fitting that is substantially perpendicular to the wall surface . That is, when the vertical plate portion is deformed, relative displacement in the horizontal direction can be allowed. Moreover, the said vertical board part has big rigidity in the direction parallel to the perpendicular | vertical surface, and does not deform | transform easily. Therefore, the top portion of the interior wall body is firmly supported in the direction perpendicular to the wall surface, and the wall body does not easily shake even if some force is applied from the living room.
[0011]
Further, the vertical plate portion is formed with a side protrusion that is bent along a horizontal line, so that the deformation of this portion causes the space between the interior wall body and the structural housing. Large relative deformation is allowed.
[0012]
The invention according to claim 3 is the interior wall body according to claim 1 or 2 , wherein the support metal fitting has a long axis in a direction substantially perpendicular to the wall surface of the interior wall body. It is assumed that a long hole is provided and is joined to the floor structure or roof structure of the upper floor by a bolt inserted through the long hole.
[0013]
In such an interior wall body, it has a long hole in a direction perpendicular to the wall surface, that is, in a direction parallel to the vertical surface of the vertical plate portion, and the support fitting is less likely to be deformed in this direction. With this long hole, the positions of the support fitting and the structural housing can be easily adjusted and joined.
Further, when a large force acts in the long axis direction of the long hole, it is possible to allow the relative displacement in the direction perpendicular to the wall surface by shifting the position of the bolt within the range of the long hole. As a result, in a portion where the wall 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 displacement between the interior wall and the structural frame is reduced. It is possible to prevent the wall body from being damaged.
[0014]
The invention according to claim 4 is an interior wall used for joining a top portion of an interior wall body standing independently of a column or wall body supporting a load and a floor structure or a roof structure of an upper floor. This is a body support bracket, which is made of a thin metal plate material, and is provided with a protruding part to the side formed by bending along a horizontal line while being erected substantially vertically And a lower attachment portion that is continuous with the lower end of the vertical plate portion and is fixed to the main body portion of the interior wall body, and a substantially vertical surface of the vertical plate portion that is continuous with the upper end of the vertical plate portion. The present invention provides an interior wall support metal fitting having a long hole having a parallel long axis and having an upper mounting portion joined to the floor structure or the roof structure by a bolt inserted into the long hole.
[0015]
Such an interior wall support bracket allows a relative horizontal displacement of the interior wall body with a simple structure at the top of the interior wall body standing independently from the structure body, It can be joined so that it does not shake easily in the direction perpendicular to the wall.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the invention according to the present application will be described with reference to the drawings.
FIG. 1 is a schematic cross-sectional view showing a configuration of an interior wall body according to an embodiment of the invention described in claim 1, claim 2, or claim 3 . Moreover, FIG. 2 is an arrow line view in the AA line shown in FIG.
The interior wall 1 is provided for interior decoration in a steel structure multi-layered building.
[0017]
The structural frame of the multi-layer building has a main part composed of a column 11 made of steel and a steel beam 12 having an H-shaped cross section, and an exterior member made of lightweight concrete on the outer surface of the structural frame. 13 is attached and constitutes an outer wall surface. Further, a floor slab 14 made of lightweight concrete is formed on the steel beam 12, and this upper surface is a floor surface of each floor.
[0018]
The interior wall body 1 which is an embodiment of the present invention is a steel in which the main body 2 is erected on the floor surface independently of the pillar 11 and the exterior member 13 and supports the upper floor via the support fitting 3. It is connected to the beam 12. Further, the lower end of the main body 2 is also fixed so as not to be displaced with respect to the floor slab 14.
[0019]
As shown in FIG. 2, the main body 2 of the interior wall body forms a frame body with a plurality of studs 4 made of wood and a cross member 5 that connects these upper and lower ends, and a decorative body is formed on the inner surface thereof. An interior material (not shown) such as plywood is pasted.
[0020]
FIG. 3 shows a front view [(a)] and a side view [(b)], and FIG. 4 shows a perspective view. The support fitting 3 is manufactured by bending a steel plate. The vertical plate portion 31 that is arranged substantially vertically during use, the upper mounting portion 32 formed by bending the upper portion at a substantially right angle, and the lower portion of the vertical plate portion 31 in the opposite direction to the upper mounting portion 32. And a lower mounting portion 33 that is bent substantially at a right angle. The vertical plate portion 31 is provided with a protruding portion 31a formed so as to protrude sideways by being bent along three horizontal lines.
[0021]
In the support fitting 3, a plurality of screw holes 33 a are provided in the lower attachment portion 33, and the main body portion 2 is arranged in a direction in which the vertical plate portion 31 is perpendicular to the wall surface of the interior wall 1. The cross member 5 is fixed with screws 34. The upper mounting portion 32 is provided with two long holes 32a having a long axis in series in a direction parallel to the vertical plane of the vertical plate portion, and the steel beam 12 is provided by a bolt 35 inserted into the long hole 32a. It is connected with the flange 12a.
In addition, although the wall 1 for interior shown in FIG. 1 stands up inside the exterior member 13, and provides interior, the partition wall 6 shown in FIG. 2 can also be made into the completely same structure.
The ceiling 15 is suspended and supported from the steel beam 12 by a suspension member 16.
[0022]
In such an interior wall body, the support fitting 3 that connects the top portion of the main body portion 2 to the steel beam 12 is formed by bending a steel plate material, and is parallel to the vertical surface of the vertical plate portion 31. Since it is difficult to deform in the direction, the displacement in the direction perpendicular to the wall surface of the top of the main body 2 can be restrained, and it can be easily shaken even with a horizontal load from the indoor side. Or supported so as not to tilt.
[0023]
Further, when a large interlayer deformation occurs during an earthquake, the main body 2 is not easily deformed in a direction parallel to the wall surface, and cannot follow a large relative displacement between the lower floor and the upper floor. 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 damage to the interior wall 1 is prevented. On the other hand, when the relative displacement of the upper and lower floors occurs 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. .
[0024]
However, in a portion where two interior wall bodies are joined at right angles, such as a joint portion between the interior wall body 1 and the partition wall 6 provided along the outer wall surface, the direction perpendicular to the wall surface can also be used. The wall is hard to deform. However, in such a portion, when a large force of a predetermined value or more acts between the support fitting 3 and the steel beam 12, the position of the support fitting 3 is shifted within the long hole 32a, and the interior wall body Damage can be reduced.
[0025]
The embodiment of the present invention described above is an interior wall in a steel structure building. However, the structure of the building is not limited to a steel structure, but a steel reinforced concrete structure, a reinforced concrete structure, or a wooden structure. Etc., or a composite structure of these.
Further, in this embodiment, the main body 2 of the interior wall 1 has a frame made of wood, but a light steel frame, an aluminum mold, or the like may be used.
[0026]
On the other hand, the support bracket is not limited to the shape shown in FIG. 3 and FIG. 4, and can have various forms as long as it has a similar function, and is particularly provided in the vertical plate portion 31. The shape of the protruding portion 31a may be an arc shape in cross section as shown in FIG. 5A or a rectangular shape as shown in FIG. 5B. Moreover, as shown in FIG.5 (c), what combined said shape may be used, and as shown in FIG.5 (d), the several protrusion part may be provided up and down.
