[0008]

[Action]

 (According to claim 1) When the abutment fixing member sways in the horizontal direction together with the floor surface due to the lateral movement of the earthquake, the abutment fixing member is placed in a posture parallel to the floor surface due to the swing of the second spherical bearing portion. While being held, the swinging movement of the first spherical bearing portion causes the support rod for fixing the moving wall to swing around the first spherical bearing portion. For this reason, the moving wall body and the floor surface are relatively swaying independently, and the moving wall body is not damaged.

(According to the second aspect) Normally, since the first spherical bearing portion is in a state in which it cannot swing, the moving wall body can be fixed to the floor surface, and the moving wall body does not wobble. When an earthquake occurs, the rolling motion of the floor surface is transmitted to the second spherical bearing, and the force that rotates the inner and outer joints acts on each other, so that the screw member is the boundary between the inner and outer joints. Shear and fracture at the surface, and the support rod for fixing the moving wall can swing freely. For this reason, the moving wall body and the floor surface can freely roll sideways, and the moving wall body is not damaged.

(According to claim 3) Since there are many small spheres between the outer connecting portion and the inner connecting portion of the second spherical bearing portion, a large vertical compressive force is exerted on the second spherical bearing portion. Even if it works, you can surely swing. Therefore, in the event of an earthquake, the abutment fixing member and the support rod for fixing the moving wall are not damaged, and the support rod for fixing the moving wall surely swings.

It should be noted that the screw hole 18 may be provided only at one place and the screw member 20 may be provided at only one.

Further, in the suspension member 2, when a bending force due to an earthquake is applied to the swing joint portion 7, the screw member 20 causes the boundary surface between the inner connecting portion 4 and the outer connecting portion 6 (a phantom line in FIG. 3). It is configured so that the swing joint portion 7 can swing freely.

In the illustrated example, the angle θ at which the moving wall body 3 can swing with respect to the axis of the upper rod portion 12 of the suspension member 2 is set to 30 ° (see FIG. 11). However, other than 30 °, it may be changed within a range of about 20 ° to 60 °.

Next, as shown in FIGS. 4, 5, and 6, the weight supporting portion 9 includes a mounting member 22 having a plurality of spherical recesses 24 ... Opening upward, and a spherical shape of the mounting member 22. Rolling balls 21 that are fitted into the recesses 24, and a number of small balls 25 that are laid on the inner surface of the spherical recesses 24 of the mounting member 22 and that receive the rolling balls 21 rotatably. , Consists of. That is, the weight supporting portion 9 has a plurality of rolling balls 21 ...

As a result, the rolling balls 21 ... Can roll smoothly even if the weight of the heavy moving wall body 3 is received.

The mounting member 22 is composed of a main body portion 22a having a rectangular shape in plan view, and retaining portions 22b, 22b which are screwed to both ends in the longitudinal direction thereof to prevent the rolling balls 21 ... from coming off. The main body portion 22a has a through hole 27 in the center. Then, the threaded portion 23 formed at the lower end portion of the slide rod portion 10 is inserted into the through hole 27 from above, and the nut member 26 is screwed into the threaded portion 23 from below, whereby the main body portion is formed. 22a is fixed to the slide rod 10.

(Returning to FIG. 2) The moving wall body 3 has an insertion hole 28 in the shape of an upper opening into which the suspension member 2 is inserted. Exterior plates 34, 34 are fixedly provided on both front and rear surfaces of the moving wall body 3. Thus, the moving wall body 3 is formed with a receiving surface 29 on which the rolling balls 21 of the weight supporting portion 9 are rotatably abutted from below.

That is, as shown in FIGS. 2 and 4, in the insertion hole 28 of the moving wall body 3, a locking member 31 having a through hole 30 for inserting the slide rod portion 10 of the hanging member 2 is fixed. The lower surface of the locking member 31 serves as the receiving surface 29.

Further, as shown in FIGS. 4 and 7, the weight support portion 9 abuts on the receiving surface 29 with left and right allowances U, which are movable horizontally along the receiving surface 29. That is, the rolling balls 21 ... Abut on the receiving surface 29 with a left and right margin allowances U, which can move in the horizontal left-right direction along the receiving surface 29 of the moving wall body 3.

Specifically, the receiving surface 29 of the locking member 31 is elongated in the left-right direction with a margin, and the through hole 30 of the locking member 31 is a long hole in the left-right direction. (See Figure 7). As a result, the hanging member 2 is slidable with respect to the moving wall body 3 in the horizontal left-right direction by a predetermined dimension W 1.

Further, the weight support portion 9 is attached to the slide rod portion 10 with a vertical allowance V that can be moved downward to separate it from the contact state (see FIG. 2). Specifically, a stepped portion 32 that faces downward is formed on the upper portion of the slide rod 10, and a stopper that faces the stepped portion 32 is provided at a position near the upper surface of the contact member 31 of the moving wall body 3. Form surface 33.

As a result, the slide rod portion 10 (that is, the suspension member 2) moves up and down between the stepped portion 32 and the stopper surface 33 when the rolling balls 21 of the weight support portion 9 are in contact with the receiving surface 29. Only the dimension H can be slid downward with respect to the moving wall body 3.

As shown in FIG. 10, the moving wall body 3 is suspended by two suspension members 2 and 2 on the left and right. Then, one suspension member 2a is slidable in the left-right direction as described above and is movable downward.

As shown in FIG. 8, the other suspension member 2b is configured to be movable downward with respect to the moving wall body 3, but not movable in the left-right direction.

That is, as shown in FIG. 9, the through hole 30 of the contact member 31 through which the slide rod 10 is inserted is a circular hole having an inner diameter slightly larger than the outer diameter of the slide rod 10. It On the other hand, the weight supporting portion 9 is composed only of a small plate piece having a rectangular shape in plan view, and does not have the rolling ball 21 and the small spherical body 25 shown in FIGS. Note that the other configurations are similar to those shown in FIGS. 2 and 3.

Due to the above-mentioned configuration, normally, as shown in FIG. 1, the moving wall fixing leg portion 35 is fixed and held in the vertical state at the lower portion of the moving wall body 3. Moreover, as shown in FIGS. 2 and 12, the suspension member 2 is held vertically and the weight support portion 9 is in contact with the receiving surface 29 of the moving wall body 2.

Then, when an earthquake occurs and the building structure shakes violently, the upper rod portion 12 of the hanging member 2 is moved upward by the horizontal shaking (horizontal shaking), as shown in FIG. As it sways in the horizontal direction as indicated by the arrow J with the suspension vehicle, rail, ceiling, etc., the screw member 20 breaks at the boundary surface between the inner connecting portion 4 and the outer connecting portion 6, and the swing joint portion 7 swings. Be free.

That is, since a bending force is applied to the swing joint portion 7 and a large shearing force acts on the tip end portion of the screw member 20, the tip end portion of the screw member 20 is broken, and the small concave portion of the inner connecting portion 4 is broken. The inner connecting portion 4 rotates with respect to the outer connecting portion 6 with the fragments 20a at the tip of the screw member 20 remaining inside the place 19.

Then, the moving wall main body 3 is made swingable around the lower portion or the vicinity thereof as shown by an arrow K, and seismic energy in the horizontal direction is absorbed. That is, since the suspension member 2 forms a joint in the swing joint portion 7 and swings, the internal stress generated in the suspension member 2 is reduced, and the suspension member 2 can be prevented from being cut. Therefore, the moving wall body 3 can be held in a suspended state on the ceiling, and the moving wall body 3 does not fall.

In addition, due to the horizontal shaking, vertical bending (hereinafter also referred to as structural secondary bending) and horizontal bending occur in the reinforcing bars and the like that form the building structure. In addition, vertical shaking (up and down) of an earthquake causes vertical bending (hereinafter sometimes referred to as seismic stress bending) in the reinforcing bars that form the building structure.

When the suspension member 2 is pushed down relative to the moving wall body 3 due to the secondary bending of the structure and the seismic stress deflection, as shown in FIGS. 13 and 14, the suspension member 2 is moved to the moving wall body 3. 3, the weight supporting portion 9 is separated downward with respect to the receiving surface 29.

With this, it is possible to absorb the bending in the vertical direction. That is, since the vertical compression force does not act on the moving wall body 3 and the hanging member 2, the hanging member 2 can be prevented from being cut and the moving wall body 3 can be prevented from being damaged. Moreover, the moving wall body 3 cannot fall.

The suspension member 2 has a vertical dimension from the normal state of FIG. 12 until the stepped portion 32 of the suspension member 2 contacts the stopper surface 33 of the moving wall body 3 as shown in FIG. Only H can be lowered relative to the moving wall body 3. Therefore, if this vertical dimension H is set to be equal to or larger than the sum of the dimension of the structural secondary deflection and the dimension of the seismic stress deflection, it is possible to absorb all the upward and downward deflections. is there.

Further, as shown in FIG. 15, the abutment fixing member 37 of the moving wall fixing leg portion 35 shifts in the horizontal direction together with the floor below it as shown by an arrow M due to the horizontal shaking, The screw member 45 of the first spherical bearing portion 38 breaks at the boundary surface between the inner connecting portion 40 and the outer connecting portion 42, and the first spherical bearing portion 38 becomes swingable.

That is, since the second spherical bearing portion 39 is always swingable, the bending force is applied to the first spherical bearing portion 38 via the moving wall fixing support rod 36, and the tip end of the screw member 45 is loaded. A large shearing force acts on the part. As a result, the tip portion of the screw member 45 is broken, and the fragment 45a at the tip of the screw member 45 remains in the small recess 44 of the inner connecting portion 40. The part 40 rotates.

Then, the leg portion 35 becomes swingable around the upper end portion. Therefore, the moving wall main body 3 and the floor surface 50 can be relatively laterally swung, although the suspension member 2 is restricted. Moreover, damage to the moving wall body 3 can be prevented.

When the first motion of the earthquake is the push-up motion of the floor surface 50, the entire moving wall is pushed up via the moving-wall fixing legs 35, and therefore, as shown in FIGS. 13 and 14. In addition, the moving wall body 3 can be raised relative to the suspension member 2 to absorb the thrust force.

Therefore, it is possible to prevent the suspension member 2, the moving wall body 3, and the leg portion 35 from being damaged, and to prevent the moving wall body 3 from falling.

Moreover, there is an advantage that the safety is high (because the moving wall body 3 does not fall down). Particularly, it has excellent earthquake resistance against rolling.

According to the seismic resistant moving wall structure of the second aspect, the same effect as that of the first aspect of the invention can be obtained, and normally, the moving wall body 3 can be held vertically fixed at a predetermined position. . Further, when an earthquake occurs, the lower end portion of the moving wall body 3 and the floor surface are allowed to sway each other, and damage to the moving wall body and damage to the floor surface can be prevented.

According to the seismic resistant moving wall structure of the third aspect, the same effect as that of the first aspect of the present invention is obtained, and in the event of an earthquake, the lower end portion of the moving wall main body 3 and the floor surface are surely in mutual contact. Since it can be rolled sideways, damage to the moving wall body and damage to the floor surface can be prevented more reliably.
