Description

TECHNICAL FIELD The present invention relates to a structure for preventing overturning of furniture arranged on a double floor having a plurality of floor panels laid on the floor via panel supports. Furniture such as cabinets and shelves (racks) are typical examples of fixtures, but there are also electric (electronic) products such as multifunction machines and refrigerators, display devices for products, and works of art. Exhibit equipment, personal computer servers, distribution boards, etc., which are placed on the floor and are likely to topple over in an earthquake.

Many proposals have been made for means for preventing overturning of cabinets in the event of an earthquake. There are two ways to prevent overturning: one is to allow cabinets to sway while mitigating the degree of it, and the other is to prevent cabinets from moving independently even in an earthquake (because the building will move during an earthquake, the cabinets will not move). The idea is that even though the hull will sway with respect to the ground, it will not move relative to the building.)

As an example of the former method, there is a seismic isolation device for moving cabinets relative to the floor, as disclosed in Patent Document 1. On the other hand, as a means for preventing the cabinets from moving independently, as disclosed in Patent Document 2, the top surface of the cabinets is connected to the wall of the building with brackets, or as disclosed in Patent Document 3. , it has been proposed to dispose an anti-toppling plate on which cabinets are placed and fixed inside the OA floor.

Japanese Patent Application Laid-Open No. 2007-037990 JP 2016-002420 A Japanese Patent No. 3541362

The means of Patent Document 1 is understood to be excellent in theory, but has the problem of being significantly complicated in structure. On the other hand, the means of Patent Document 2 has a simple structure, but cannot be applied to a layout in which the cabinet is placed away from the wall of the building (so-called island placement), or if the height of the cabinet is high, brackets and the like cannot be attached. is troublesome. Moreover, the means of Patent Document 3 has the problem that it takes a lot of time and effort to install the overturn prevention plate in the access floor, and the problem that it is not applicable to floors other than access floors and is inferior in versatility.

In addition, the most common and simple overturn prevention means is a means for fixing directly to the floor or the wall. However, when the fixtures are fixed to the floor panel of the OA floor, there is a risk that the floor panel to which the fixtures are fixed may be lifted when the fixtures tilt due to the shaking of the floor due to an earthquake or the like, and the fixtures may topple over together with the floor panel. There is also a type of OA floor provided with a panel pressing member that presses and fixes the four corners of the floor panel from above. However, even with such a type, there is a risk that the panel holding member will be damaged when the furniture is tilted, and the furniture will topple along with the floor panel.

The present invention was made in response to such a situation, and aims to prevent the overturning of fixtures fixed to the floor panels of a double floor.

<Overview of First Embodiment>
Next, embodiments of the present invention will be described based on the drawings. First, an embodiment shown in FIGS. 1 to 11 will be described. This embodiment is applied to prevent overturning of a steel cabinet 1 formed in a horizontally long rectangular shape in plan view.

As shown in FIGS. 1 to 4, the cabinet 1 is placed on a floor F of a double floor structure having a plurality of floor panels 53 laid on a floor slab 51 (floor surface) via panel supports 70. be done. The cabinet 1 includes a cabinet body 2 opening forward, a horizontally rotatable double door 3 for opening and closing the opening, and a steel plate base 4 on which the cabinet body 2 is placed. Since the depth of the cabinet 1 is much smaller than the height, it is likely to fall forward or backward during an earthquake. Therefore, the overturn prevention device 6 is used in this embodiment.

As shown in FIGS. 1, 4, and 7 to 11, a fixing screw 10 (an example of a fixture) for fixing the cabinet 1 to a fixture fixing floor panel 53A selected from a plurality of floor panels 53 and a fixture A panel restricting member 60 is provided to prevent the fixed floor panel 53A from being lifted. As shown in FIGS. 7 and 8, the cabinet 1 is placed on the floor F across two furniture-fixing floor panels 53A. Four panel restricting members 60 are arranged at locations corresponding to the four corners of the cabinet 1 . 7 and 8, illustration of the floor finishing material 54 is omitted.

The panel supporter 70 has a support pedestal 72 that laterally protrudes from the upper part of the support leg 71 erected on the floor slab 51 and supports the edge 53 a of the floor panel 53 . The panel regulating member 60 includes an insertion portion 61 that vertically passes through a gap S between the furniture fixed floor panel 53A and the adjacent floor panel 53B, and a portion extending from the upper end of the insertion portion 61 toward the furniture fixed floor panel 53A. It has an upper locking portion 62 that extends and a lower locking portion 63 that extends downward from the lower end of the insertion portion 61 toward the bottom of the support seat portion 72 . The panel regulation member 60 is made of a metal plate.

As shown in FIGS. 1 and 4, the overturn prevention device 6 is installed between the floor F and the cabinet 1 to prevent the cabinet 1 from overturning. In this embodiment, a pair of left and right overturn prevention devices 6 are provided below the cabinet 1 . The left and right overturn prevention devices 6 have the same shape, and are configured by elastic metal (steel plate) plates placed on the floor F below the cabinet 1 .

The overturn prevention device 6 includes a plate-shaped base 7 in contact with the floor F, a pair of front and rear connecting portions 8 provided at the front and rear ends of the base 7, and the base 7 at a position between the front and rear connecting portions 8 in a plan view. It has a fixing part 9 provided in. The connecting portion 8 is connected to the base 4 of the cabinet 1 by a screw-type adjuster member 23, while the fixing portion 9 is fixed to the floor F (furniture fixing floor panel 53A) by the fixing screw 10, so that the cabinet 1 is It is fixed to the floor F (furniture fixed floor panel 53A) via the overturn prevention device 6 .

It should be noted that the fixture for fixing the overturn prevention device 6 to the fixture fixed floor panel 53A is not limited to the fixing screw 10. FIG. For example, a scissors-fixed anchor member 11 (see FIG. 13) such as an IT hanger may be used to fix the overturn prevention device 6 (cabinet 1) to the furniture fixed floor panel 53A.

In this embodiment, even if the furniture fixing floor panel 53A tries to be lifted when the floor F shakes due to an earthquake or the like, the lower locking portion 63 of the panel restricting member 60 is attached to the support pedestal portion 72 of the panel support 70. The furniture fixed floor panel 53A is prevented from being lifted by being caught. Thereby, overturning of the cabinet 1 can be prevented. In addition, the panel control member 60 can be realized with a simple structure formed by bending a sheet metal, for example, and can be attached to an existing double floor structure without additional work, etc., so that this embodiment is low cost and A simple operation can prevent furniture from falling over.

In addition, in this embodiment, by fixing the cabinet 1 to the fixture fixing floor panel 53A of the floor F via the overturn prevention device 6, overturning of the cabinet 1 due to an earthquake or the like can be prevented. In addition, when the cabinet 1 rocks due to an earthquake or the like, the base portion 7 of the overturn prevention device 6 is elastically bent and deformed, thereby reducing the force applied to the fixed portion 9, and the overturn prevention device 6 from the floor F. Peeling can be suppressed.

In addition, in this embodiment, the overturn prevention device 6 and the cabinet 1 are connected at two front and rear locations using the front and rear connection portions 8 with the fixing portion 9 interposed therebetween. As a result, the overturning of the cabinet 1 can be prevented while suppressing the separation of the overturning prevention device 6 from the floor F against shaking in two directions (forward and backward).

<Floor configuration>
As shown in FIGS. 4 and 7 to 11, in this embodiment, the floor F has a double floor structure called an OA floor. Specifically, the floor F consists of a floor panel 53 that is supported on a floor slab 51 such as a concrete slab with a space provided between it and the floor slab 51 by support legs 71, and a floor panel 53 that is laid on the floor panel 53. and a floor covering 54, such as a torched carpet. The floor panel 53 is made of metal or concrete, for example.

As shown in FIG. 9 , the panel support 70 includes support legs 71 erected on the floor slab 51 , support pedestals 72 projecting laterally from the tops of the support legs 71 , and positioning plates attached to the upper surfaces of the support pedestals 72 . It has a member 73 and a holding member 74 attached to the top of the positioning member 73 . The support leg 71 has a height adjusting function, and a flange portion 71a provided at the bottom of the support leg 71 is fixed to the floor slab 51 with an adhesive, a bolt, or the like (not shown). The support pedestal 72 is donut-shaped and disk-shaped, and is fixed to the upper end of the support leg 71 by welding or the like. Four radially extending pedestal projections 72a are provided on the upper surface of the support pedestal portion 72 at regular intervals in the circumferential direction. The support legs 71 and the support base portion 72 are made of metal.

The positioning member 73 is made of resin and has four positioning ribs 73c extending in all directions from the side surface of a cylindrical portion 73b projecting from the center of the upper surface of a disk-shaped base portion 73a. The base portion 73a and the rib portion 73c are provided with recesses into which the support base portion 72 and the base projections 72a are fitted. By fitting the positioning member 73 into the support pedestal portion 72 from above, the engaging claws (not shown) provided on the peripheral edge rib portion of the base portion 73a are engaged with the peripheral edge portion lower surface of the support pedestal portion 72, thereby forming the support pedestal. The portion 72 and the positioning member 73 are connected so as not to come off.

As also shown in FIG. 7, the floor panel 53 has a substantially square shape in a plan view, and cutout portions 53b are formed at four corner portions 53e (also edge portions 53a). The upper surface of the corner 53e is formed with a substantially quarter-circular recess 53c into which a pressing member 74, which will be described later, is fitted. A buffer member 53d made of an elastic material such as rubber is provided on the lower surface of the corner 53e.

As shown in FIGS. 7 and 9, a large number of panel supports 70 are erected on the floor slab 51 in a grid pattern at regular intervals. Corner portions 53 e of four floor panels 53 are arranged on the support pedestal portion 72 of each panel support 70 . That is, each floor panel 53 is supported by four panel supports 70 . Adjacent floor panels 53 are arranged close to each other. Between the adjacent floor panels 53, the rib portion 73c of the positioning member 73 is interposed in the vicinity of the corner portion 53e, while a gap S is formed at a position not overlapping the panel support 70 in plan view.

As shown in FIG. 9 and the like, a pressing member 74 is detachably attached to the upper end of the cylindrical portion 73b of the positioning member 73. As shown in FIG. The pressing member 74 is made of resin and has a threaded portion 74b hanging down from the center of the lower surface of a disc-shaped pressing portion 74a that fits into the concave portions 53c of the four floor panels 53 placed on the support base portion 72 . By screwing the threaded portion 74b of the pressing member 74 into a female thread (not shown) cut in the inner wall of the cylindrical portion 73b of the positioning member 73, the pressing member 74 is connected to the positioning member 73 so as not to come off, and the pressing portion 74a is attached to the positioning member 73. It fits into the recess 53c of the floor panel 53 and faces the upper surface of the corner 53e. As a result, lifting of the floor panel 53 is suppressed.

Instead of the pressing member 74, a metal disk-shaped cap member having a screw insertion hole in the center may be used, and the cap member may be connected to the support leg 71 with a screw member. In this case, a screw hole is provided on the upper end side of the support leg 71, and the screw hole is exposed on the upper surface side of the support base portion 72, and the screw member inserted from above into the screw insertion hole of the cap member is used as the positioning member. 73 is screwed into the screw hole of the support leg 71 via the cylindrical portion 73b. As a result, the cap member is directly connected to the support leg 71, so that lifting of the floor panel 53 can be suppressed more firmly.

In this manner, the floor panel 53 is prevented from rising by the pressing member 74 . However, with respect to the furniture fixed floor panel 53A to which the cabinet 1 is fixed, when the cabinet 1 tilts due to shaking of the floor F due to an earthquake or the like, a force acts in the direction in which the furniture fixed floor panel 53A is lifted, and the holding member 74 is damaged. It could not be said that it was a sufficient fall prevention measure. Therefore, in this embodiment, a panel restricting member 60 is attached to the floor F of the double structure to prevent the furniture fixed floor panel 53A from rising.

<Structure of Panel Regulating Member>
As shown in FIGS. 4, 10 to 12, and the like, the plate-like upper engaging portion 62 of the panel restricting member 60 has a substantially quadrangular shape in plan view. A plate-shaped insertion portion 61 along the one side hangs down. A plate-shaped lower engaging portion 63 extending along the one side of the upper engaging portion 62 in plan view extends from the lower end portion of the insertion portion 61 . The insertion portion 61 and the lower locking portion 63 are in an inverted T shape when viewed from the side.

A pair of tilt suppressing portions 64 that sandwich the base end portion of the insertion portion 61 extends from both edge portions of the one side of the upper locking portion 62 . The insertion portion 61 and the pair of tilt suppressing portions 64 are concave in plan view. Both edges of the lower engaging portion 63 in the direction along the one side are positioned below the tilt suppressing portion 64 .

<Installation of panel control members>
As shown in FIGS. 10 to 12, the thickness of the insertion portion 61 and the lower locking portion 63 is set smaller than the gap S. As shown in FIG. The insertion portion 61 and the lower locking portion 63 are inserted into the gap S from above before the floor finishing material 54 is laid or after the floor finishing material 54 has been removed (see the upper diagram of FIG. 10).

The panel restricting member 60 is inserted into the gap S with the upper engaging portion 62 positioned above the fixture fixed floor panel 53A. The upper engaging portion 62 abuts on the upper surface of the furniture fixed floor panel 53A, and the tilt suppressing portion 64 abuts on the upper surface of the adjacent floor panel 53B, thereby maintaining the vertical posture of the insertion portion 61 and the lower engaging portion 63 (middle of FIG. 10). (Refer to the figure and the middle diagram of FIG. 11).

Next, the panel regulating member 60 is slid along the gap S to dispose the lower engaging portion 63 below the support seat portion 72 (see the bottom diagram of FIG. 10 and the bottom diagram of FIG. 11). For example, the panel restricting member 60 is slid until the end of the lower engaging portion 63 contacts the support leg 71 .

When a force is applied in the direction in which the furniture fixed floor panel 53A is lifted up, the lower engaging portion 63 of the panel restricting member 60 contacts the lower surface of the support pedestal portion 72 (positioning member 73), and the upper engaging portion 62 It restricts the upward movement of the fixed floor panel 53A. Thereby, the panel restricting member 60 can prevent the furniture fixed floor panel 53A from rising. Also, the panel regulation member 60 can be installed without peeling off the floor panel 53, so workability is good.

Even if the panel support body 70 is not provided with the pressing member 74, by positioning the lower locking portion 63 of the panel restricting member 60 below the support pedestal portion 72, the fixture fixed floor panel 53A can be secured. It can prevent floating.
