Abstract

PURPOSE: To prevent an easy collapse regardless of an unbalanced load, and improve strength by passing a bolt through a movable base made of a base with standing pieces from both sides of a horizontal piece and suspended pieces from top plate ends engaged to each other, and a top plate respectively from a lower position, and supporting the bolt on the horizontal piece. CONSTITUTION: A vertical load is supported on a bolt 7 held with a horizontal piece 8, and a horizontal load is supported on both of a suspended piece 13 and a standing piece 9. In addition, the standing piece 9 and the suspended piece 13 are connected to the periphery of the horizontal piece 8 and a top plate 12 integrally to prevent the occurrence of buckling. Inclination due to an unbalanced is thereby restrained, and strength is increased. In addition, directionality for a horizontal load is kept free, so as to be pertinent for the pillar of a freely accessible floor. At the same time, the horizontal piece 8 is secured to a floor rail 2 to reinforce the strength thereof. The collapse of the rail 2, a base board 3 and a height adjusting tool 1 is thereby prevented. According to this construction, a mounting pitch for providing the tool 1 is enlarged, and cost is reduced. In addition, the rail 2 is made lightweight and manpower can be saved for a construction work.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a height adjuster applied to movable partitions, columns for free access floors, etc., and a skirting board mounting device applied to movable partitions.

[0002]

2. Description of the Related Art A conventional example of a movable partition is shown in FIGS. That is, FIG. 11 is a perspective view of the appearance of the movable partition, and FIG. 12 is an exploded perspective view of the height adjuster, and FIG.
3 shows a sectional view of the height adjuster. The movable partition includes a ceiling rail 70 attached to the ceiling surface, a floor rail 71 attached to the floor surface 84 directly below the ceiling rail 70 with screws 78 (FIG. 12), and a height adjusting tool placed in the floor rail 71. 7
2 (FIG. 12) and a height adjuster 72 fitted to the floor rail 70.
Skirting board 73 placed on the ceiling rail 70 and skirting board 7
It has a stud 74 built between the three, and a panel 76 whose lower end is supported by the skirting board 73 and locked in the hole 77 of the stud 74 by the stopper 75.

The height adjuster 72 is an inverted U-shaped base 80.
And a bolt 81 that has a support portion 83 in the middle and is screwed into the center of the base 80, and a movable base 82 that has an inverted U shape and that fits into the base 80 and is inserted into the bolt 81. . The height adjuster 72 is inserted into the floor rail 70, the bolt 81 is passed through the long hole 86 of the skirting board 73, and the skirting board 73 is attached to the movable base 82 by the nut 84.

Conventional examples of columns for a free access floor are shown in FIGS. 14 to 17. That is, FIG. 14 is an overall configuration diagram of the free access floor, and FIGS. 15 to 17 are half-sectional side views of the height adjuster. In order to use the underfloor as a wiring space for electric wiring, a pillar-shaped height adjuster 90 is fixed on the surface of the building slab for each set dimension, and a panel 91 is placed above it. The height adjuster 90 of FIGS. 15 and 16 includes a fixed column 93, a movable column 94 having a threaded portion 95 fitted to the fixed column 93, and a fixed column 93 supported by the threaded portion 95. Has a nut 96,
By rotating the nut 96, the movable column 94 can be raised and lowered. The height adjuster 90 of FIG. 17 slides the screw portion 95 upward and rotates the nut 96 to adjust the level. There are many types of height adjusters as shown in FIGS. 15 to 17 depending on the difference in seismic load (horizontal load) and load (vertical load).

[0005]

However, in the case of the movable partition, since the total load of the panel 76 is applied to the skirting board 73, the height adjusting tool 72 and the floor rail 70, the panel 7 is not supported.
When only one side of 6 is installed, an eccentric load is applied to the skirting board 73, the height adjusting tool 72, and the floor rail 70, and a slight fall like an imaginary line occurs. Once a fall occurs, even if another panel 76 'is placed on the opposite side, it does not completely return to its original state, and the space between the ceiling rail 70 and the stud 74 and the upper portion of the panels 76, 76'.
Due to friction between the ceiling rails 70, between the skirting board 73 and the floor rail 71, and between the height adjuster 72 and the floor rail 71, the front and back panels 76 and 76 'appear as a step difference. As a countermeasure, it is necessary to strengthen the floor rail 71 so that the floor rail 71 can withstand an unbalanced load.

The height adjuster applied to the support pillar for the free access floor is generally an elongated column member, which is strong against a vertical load but weak against a horizontal load and easily buckles. Therefore, when designing the column, it is necessary to determine the dimension of the outer diameter of the elongated column member in accordance with the magnitude of the horizontal load. When the column is thickened, it is strong against horizontal load but excessively designed against vertical load. Further, when an eccentric load occurs, the panel receiving portion on the upper part of the support column tilts (falls down) and a step is formed between adjacent panels.

Therefore, an object of the present invention is to provide a height adjuster and a skirting board attaching device which are hard to fall against an unbalanced load and whose strength can be increased.
