Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention is a construction method of laying a border floor at a so-called border portion such as a wall of a room with a floor base and an appropriate vertical gap (border). Floor manufacturing method).

[Conventional technology]

As a prior art for supporting the height of the border panel in the so-called border portion, for example, in Japanese Utility Model Laid-Open No. 62-14039, a board for contacting a floor base is screwed with a bolt for height adjustment. There is disclosed a configuration in which a border panel is supported by a support metal fitting made of a horizontal upper plate that fits.

And, in the so-called border part which is a corner part or one side part of the room, since there is only a halfway gap shorter than the width or length of the floor panel for the free access floor formed in a predetermined size in advance, Like the border panel in the prior art, a wooden plate material is separately cut and aligned according to the gap size of the border portion, and this border panel is laid.

On the other hand, as a structure of a floor panel, a corrugated sheet made of so-called thin steel plate, which is formed by continuously forming rib portions having a trapezoidal cross section, as in Japanese Utility Model Publication No. 63-20763 is well known.

[Problems to be Solved by the Invention]

In general, furniture such as cabinets is often placed along the wall surface at the border part, so it is said that the border panel is made of a wooden board, although the rigidity of the border floor must be increased. However, the rigidity cannot be increased unless the plate thickness is increased.

Further, the work of cutting and aligning these border panels and floor panels in accordance with the above-mentioned gap size is a so-called actual work performed at the construction site, and there is a problem that it is troublesome to align the sizes exactly.

In particular, when there is a pillar part in the middle of the wall surface or the border part is not a rectangular shape in plan view but a trapezoidal shape in plan view, the direction from the floor panel side for the free access floor to the wall surface ( If the width (width of the border) is different depending on the location, it is extremely difficult to cut the border panel into a trapezoidal shape in plan view, or to cut a so-called corrugated plate so as to cross the corrugated groove. There was a problem that was troublesome.

The present invention aims to solve these problems.

[Means for solving the problem]

To achieve this object, the present invention provides a plurality of joist members or legs whose height can be adjusted on the floor base of a room, and among the joist members, a plurality of joist members or legs on the side close to the room wall surface. On the body, a lower panel having upward reinforcing ribs extending at a constant interval so as to intersect the chamber wall surface in plan view is placed such that the end faces of the upward reinforcing ribs are close to the chamber wall surface,
On the lower panel, a top panel is placed on the side closer to the wall surface of the room, while the upper panel placed on the lower panel is provided with longitudinal downward reinforcing ribs protruding from the upper panel at regular intervals. In the state of being positioned between the upward reinforcing ribs in the above, the construction is adopted in which the reinforcing ribs are displaced in the longitudinal direction and arranged adjacent to the top panel.

[Functions and effects of the invention]

According to the construction method of the present invention, since the upward reinforcing ribs projecting on the lower panel and the downward reinforcing ribs projecting on the upper panel both extend in the intersecting direction such as orthogonal to the wall surface in plan view, When the upper panel is displaced from the lower panel along the longitudinal direction of the reinforcing ribs while the reinforcing ribs mesh with each other, the width direction between the lower panel and the upper panel (longitudinal direction of the reinforcing ribs) In accordance with the change in the overlapping size, the width of the size from the outer edge of the lower panel to the outer edge of the upper panel (so-called border floor) can be changed arbitrarily and steplessly.

Therefore, when the lower panel joist member or leg is placed on the side closer to the wall surface in the border portion, and the upper panel is placed on the side farther from the wall surface on the lower panel, the side end of the upper panel and the wall surface So that the top panel fits in the gap between
By simply cutting the upper plate portion of the top panel and placing the top panel on the lower panel, the upper surface of the top panel and the upper surface of the upper panel are located at the same height, and the top panel and the upper panel are It is possible to completely close the border portion without causing a step between the two.

Further, since it is not necessary to take troublesome work such as cutting the reinforcing ribs on the upper panel and / or the lower panel, and only the upper plate (which is a flat plate) of the top panel is cut, the construction method is extremely simple. .

Further, since the reinforcing ribs are provided on both the upper panel and the lower panel, high rigidity can be obtained similarly to the corrugated panel, and sufficient strength can be given to the border floor.

Further, even if the interval (pitch) between the upward reinforcing ribs provided on the lower panel and the interval (pitch) between the downward reinforcing ribs provided on the upper panel are the same, the downward direction is smaller than the width dimension of the upward reinforcing ribs in the pitch direction. If both reinforcing ribs are formed so that the width of the reinforcing ribs in the same direction is short and there is a gap between the sides of both reinforcing ribs, the downward reinforcing ribs of the upper panel will be placed between the adjacent upward reinforcing ribs of the lower panel. As a result of being able to position not diagonally in plan view but diagonally, as described above, even in non-parallel places where the width dimension of the border part changes continuously from the long position to the short position, The effect is that the border floor can be easily constructed simply by cutting the plate into a predetermined width shape.

〔Example〕

Next, an embodiment of the present invention will be described with reference to the drawings.
In the figure, reference numeral 1 indicates a floor panel having a rectangular shape in plan view for a free access floor, which is vertically and horizontally aligned on a floor base A, and each floor panel 1 includes a thin box-shaped support frame and a metal plate upper plate. A lightweight and high-rigidity reinforcing member such as a honeycomb member made of a non-combustible material is sandwiched between the two, and the upper plate has four side edges bent downward.

Further, each floor panel 1 is supported by a long joist member (not shown) with an adjuster border so that its height can be adjusted.

Reference numeral B shown in FIG. 1 and FIG. 2 is a space gap between the floor panels 1 of which a large number have been laid and whose side faces face the room wall surface C, and is referred to as a border portion B.

Further, reference numeral D is a pillar protruding from the floor base A in the middle of the room wall surface C.

Reference numeral 2 shown in the drawing is an elongated joist member arranged on the floor base A along the room wall surface C of the border portion B or the side surface of the pillar body D. The adjuster bolts 3 are screwed at appropriate intervals so as to be vertically movable, and the base body 4 is attached to the lower ends of the adjuster bolts 3.

The border floor laid on the border portion B is a lower panel 5 placed on a plurality of joist members 2 on the side of the joist member 2 closer to the chamber wall surface C, and an upper part that can be placed on the bottom panel 5 while being offset from each other. It consists of a panel 6 and a top panel 7.

As shown in FIGS. 1 and 5, the lower panel 5 includes a bottom plate 8 made of a thin metal plate and an upward reinforcing rib 9 fixed to the upper surface of the bottom plate 8 by spot welding or the like. As shown in FIG. 5, the first embodiment of No. 9 has a substantially trapezoidal cross section or a rectangular shape (height dimension H1, width dimension W1) that extends so as to intersect with the chamber wall surface C in a plan view and is continuously spaced at regular intervals. It is formed by bending at (P1).

On the other hand, the upper panel 6 is one in which downward reinforcing ribs 11 are provided on the lower surface of a top plate 10 made of a thin metal plate at the same fixed interval (P1) as described above, and as shown in FIG. 5 in the first embodiment. In the same manner as the upward reinforcing rib 9, a substantially trapezoidal or rectangular cross section (height dimension H2, width dimension W2) that extends so as to intersect with the chamber wall surface C in a plan view is continuously arranged at regular intervals (P1). Formed by bending.

When the upper panel 6 is placed on the lower panel 5,
Height dimension (H2 <H
It is set so as to be 1), and is formed so that a gap of an appropriate size (e) exists between the side faces of the upward reinforcing rib 9 and the downward reinforcing rib 11.

Further, as shown in FIG. 1 and the like, the top panel 7 includes an upper plate 12 and an edge piece 13 whose one side is bent downward,
The plate thickness dimension (to) of the upper plate 12 is the top plate of the upper panel 6.
The sum of the plate thickness dimension (t1) of 10 and the plate thickness dimension (t1) of the downward reinforcing rib 11 (t0 = t1 + t2).

Then, the lower panel 5 is arranged so that the end face of the upward reinforcing rib 9 is close to the chamber wall surface C (in other words, the longitudinal direction of the upward reinforcing rib 9 intersects the chamber wall surface C at a right angle and the like in plan view). ) Is placed on joist members 2, 2, and on this lower panel 5, the top panel 7 is placed on the side closer to the chamber wall surface C, while the upper panel 6 is placed on the far side. The lower surface of one side of 6 is placed on another joist member 2 (may be shared with the support of the floor panel 1). At this time, the longitudinal downward reinforcing ribs 11 projecting from the upper panel 6 at a constant interval are arranged while being displaced in the longitudinal direction while being positioned between the upward reinforcing ribs 9 of the lower panel 5, The one end face is brought close to or abutted with the side end face of the floor panel 1.

By doing so, the width dimension (H3) of the border portion B shown in FIG. 2 and the width dimensions of the upper and lower panels 5 and 6 are H4 and H4 '.
(H4 'is narrower than H3), and when the width dimension H4 is narrower than the width dimension H3 of the border portion B, the difference dimension H5 = H3
-H4 only has a gap between the chamber wall surface C and the other side edge of the upper panel 6, so the top panel 7 should be filled to fill this gap.
Cut off the upper plate 12 along the cutting line 14 indicated by the alternate long and short dash line,
The top panel 7 is placed on the lower panel 5, and the downward edge pieces 13 of the top panel 7 are attached to the chamber wall surface C and the lower panel 5.
Insert it in the gap with the side end surface of.

As a result, the top panel 7 and the upper panel 6 can be disposed on the lower panel 5 so as to be adjacent to each other without a gap, and the upper plate 12 and the upper panel 6 in the top panel 7 can be arranged.
Since the top plate 10 and the top plate 10 have the same height, no step is formed.

Even when the width dimension (H3) in the border portion B changes along the longitudinal direction of both the upper and lower panels 6 and 5, the upper panel 6 and the both reinforcing ribs are flat with respect to the lower panel 5. By arranging the upper panel 6 slightly obliquely instead of in parallel, the one end surface of the upper panel 6 can be arranged without a gap with the side end surface of the floor panel 1, while the chamber wall surface C and the other side edge of the upper panel 6 are arranged. The upper plate 12 of the top panel 7 may be cut and fitted into the gap between them in a predetermined shape.

As a second embodiment in which the upper panel 6 can be arranged so as to be slanted with respect to the lower panel 5 as described above, as shown in FIG. , 15 projecting in a comb-teeth shape at a constant interval (P1), downward reinforcing ribs 16 projecting in a comb-teeth shape on the upper panel 6 at the same interval (P1), and the pair of upward reinforcing ribs 15 The downward reinforcing rib 16 may be arranged so as to be displaced in the gap (W3) between the first and the second positions.

Further, as a third embodiment, as shown in FIG. 7, both reinforcing ribs 17 and 18 in the upper panel 6 and the lower panel 5 may be formed in a curved continuous wave shape.

Further, when there is a columnar body D having a projecting depth (H6) and a length (L) in the middle portion of the room wall surface C in the border portion B, the construction method is as shown in FIG. The front end portion or the rear end portion of the above is cut along the cutting line 19 by substantially the same length (L), and the end portion 5'is along the front surface of the columnar body D on the joist members 2,2. Put them on the slide, and the upper panel 6
It may be placed across the lower panel 5 and the end 5 ',
If the cutting line 19 of the lower panel 5 is a flat plate portion that does not traverse the bent portion of the upward reinforcing rib 9, the cutting operation becomes easier.

In addition, the upper panel 6 has the same upward reinforcing ribs 9 projecting from the lower panel 5 and the end portion 5 '.
It does not become an obstacle when the downward reinforcing rib 11 is vertically displaced.

On the other hand, the top panel 7 is also cut at its front end portion or rear end portion in the longitudinal direction along the cutting line 20 by approximately the same length (L), and the width dimension (H7) of the upper plate 12 of the end portion 7 '. ),
Cut along the cutting line 21 so as to be set to be equal to the size of the gap between the front surface of the pillar body D and the other end of the upper panel 6, and make the end portion 7 ′ of the pillar body D along the front surface to the end portion. It should be placed on 5 '.

Whichever construction method is used, it is possible to eliminate the work of cutting the upper panel and the work of cutting across the upward reinforcing ribs of the lower panel, and the work of cutting the flat top panel is sufficient. Very easy to use.

The top panel 7 does not have to include the edge piece only with the upper plate. In this case, it may be arranged so that the side end surface of the lower panel 5 is brought into contact with the chamber wall surface C.

Further, the lower panel 5 may be fixed to the joist member 2 by screwing or the like to prevent the displacement.

In the present invention, instead of the long joist member, an independent leg that supports the lower panel and the upper panel at appropriate lower surface portions may be used.

The upper and lower panels 5 and 6 and the top panel 7 may be made of a metal plate such as a duralumin plate, a steel plate, or a steel plate having vibration resistance, and a phenol resin, an epoxy resin, or a polyacetal having relatively large mechanical strength. A resin, a polycarbonate resin, an ABS resin, a polyamide resin, a polyester resin, or a glass fiber reinforced plastic in which these resins contain short glass fibers may be used.

Reference numeral 22 is a carpet laid over the upper surfaces of the floor panel 1, the upper panel 6 and the top panel 7.
