Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a floor unit, and more specifically, to a floor unit for halls, offices, etc.

[Conventional technology]

Up to now, in order to assemble a floor in an office computer room, etc., a plurality of floor posts 10 have been installed to a certain standard on the installation surface, that is, a concrete floor surface, as shown in FIGS. 4 and 5, for example. Therefore, the arrangement is fixed, and the floor beams 14 are stretched between the respective floor posts 10.
There is one in which a floor board 15 made of aluminum or the like of a certain standard is mounted on the floor beam 14 without any gaps.

In such a floor unit, the floor post 10 has a base portion 11 that is affixed or nailed to the floor surface, and a lower end that fits into a bolt hole provided at the center of the base portion 11. The insertion bolt 12 serves as an intermediate joint, and its lower end female threaded portion (not shown) is screwed into the reverse threaded bolt portion at the upper end of this insertion bolt 12, making it possible to adjust the height within a certain range. It consists of a turnbuckle-shaped beam receiving block 13. This beam receiving block 1
A plurality of locking protrusions are provided on the upper surface of the floor beam 14 to lock with interlocking grooves (not shown) formed in the lower surface of the floor beam 14, so as to prevent the floor beam 14 from wobbling laterally. It is common that the

In such a floor unit, when performing electrical wiring, it is common to cut out a portion of the floorboard 15 and fit a joint box from below.

[Problem that the invention attempts to solve]

By the way, in conventional floor units, the cost is not only high because the floor post consists of a base part, an insertion bolt, and a beam receiving block, and because a floor beam is used.
It is difficult to reduce the size beyond a certain limit, and the height of the floor unit above the floor surface is usually at least 10% of the floor height in general buildings. Also, because the unit has many parts, its assembly is quite complex. Furthermore, for grounding and electrical wiring work, it is necessary to avoid the floor posts, cut out the floorboard separately, and fit joint boxes etc. from below in the required places, and also to install electrical wiring or piping separately. Therefore, piping work, design changes or relocation of halls, offices, etc. are extremely complicated and expensive.

This idea was developed against the background of the above-mentioned circumstances, and by adopting a hollow cylindrical post member with a bottom, a floor unit with a simple structure, easy to assemble, and a significant reduction in cost was created. is intended to provide.

[Means for solving problems]

In order to solve the above-mentioned problems, this idea involves integrally molding the bottom of the post member and the hollow supporting part in the floor unit, and changing the structure of the hollow supporting part to a hollow cylindrical shape with a plurality of semicircular arches. By forming the post member with a notched opening, the hollow part of the post member can be used as a joint box for electrical wiring, etc., and at the same time, a board is screwed into the upper end of the post member. A post member is composed of a supporting adjustment ring and a cylindrical flat cap that is screwed onto the inner peripheral surface of this adjustment ring, and the four corners of the board mounted on the upper surface of the adjustment ring of the post member also contact the outer peripheral part of the flat cap. It is characterized in that a notch is formed so as to make contact with each other.

[Effect]

This idea was developed to connect the earth wire and electrical wiring to the post member of the floor unit, which is supported floating above the installation surface by placing the notches at the four corners of the board on the top end surface of the adjustment ring and abutting against the outer peripheral surface of the flat cap. A bottom part with fixing bolts planted on the surface, and a hollow cylindrical hollow support integrally formed with the bottom part and having a plurality of semicircular arch-cut openings at the bottom and a female thread on the inner peripheral surface of its upper end. A base body is constituted by the hollow cylindrical shape, and an adjustment ring having a thread on the outer circumferential surface of the lower end and a female thread on the inner circumferential surface of the upper end is attached to the female thread on the inner circumferential surface of the upper end of the hollow support. By rotatably screwing the cap to adjust the floor height of this floor unit, and by providing a screw on the outer circumferential surface of the lower end of the flat cap and screwing it into the female thread on the inner circumferential surface of the upper end of the adjustment ring. Adjust the protruding height of the flat cap depending on the thickness of the board or the situation.

〔Example〕

Next, one embodiment of this invention will be described in detail based on the accompanying drawings.

FIG. 1A is an exploded perspective view of a post member according to an embodiment of this invention, and FIG. 2 is a side sectional view including a portion of the board.

1 and 2, the floor unit according to this embodiment has a flat cap 2,
It is composed of an adjustment ring 1, a base body 3, and a board 4.

The adjustment ring 1 has a somewhat thick hollow cylindrical shape, and has a female thread 11 on the inner circumferential surface of the upper end and a thread 12 on the outer circumferential surface of the lower end.

The flat cap 2 has a cylindrical shape with a flat top end surface, and its diameter matches the inner diameter of the adjustment ring 1.
A male thread 211 is provided which is screwed into the female thread 11 on the inner peripheral surface of the upper end of the adjustment ring 1. This flat cap is a flat cap with a hole 2 which has an opening on the top end surface and has one or more through holes 21 that serve as embedding seats for connectors, sockets, etc. in order to connect power distribution lines.
It is convenient to have at least two types available for selection: 0 (see FIG. 1B) and a blind flat cap 2 having no holes.

The base body 3 includes a disk-shaped bottom portion 32 and a hollow support portion 31 integrally formed on the upper surface of the bottom portion 32. The hollow support portion 31 has four semicircular arch-shaped notched openings, and is provided with a female thread on the inner circumferential surface of its upper end that engages with the male thread 12 on the outer circumferential surface of the adjustment ring. Four nuts 331 are installed near the periphery of the bottom 32 of the base body 3 at positions facing the center of the semicircular arch opening to lock ground wires, power distribution lines, etc., or A wiring bolt 33 for fixing saddles and clips for electrical piping can be screwed on.

This wiring bolt 33 has a screw in the lower part 332 and a bolt head in the upper part.
Locking holes 3 that intersect vertically and horizontally to hold electric wires
33,334 will be provided. This wiring bolt 33
It is possible to fix electrical wiring saddles or clips, and if no piping is used,
It is also possible to lock the electric wires by passing cable ties or the like directly through the locking holes 333 and 334. Further, this wiring bolt 33 can also be used as a ground terminal.

The board 4 may be a board made of any known material, and as shown in FIG. 3, it is cut into a substantially square shape, and at each of the four corners, a flat cap 2 or a board is placed with the sides of the adjacent board abutting each other. A quadrant-shaped notch 41 is in contact with 20.
is formed. The board 4 is supported by the upper end surface of the adjustment ring 1 at the peripheral edge of the notch 41.

[Effect of idea]

As mentioned above, this invention eliminates the need to use floor beams in the floor unit and adopts the structure of the post member that also serves as an electrical box. Since additional processing such as cutting out the board placed on the top of the unit is not required, it is possible to provide a floor unit with a simpler structure and simple assembly work that can be completed in a short time, reducing both cost and time. It has industrial value.
