Description

  The present invention relates to a free access floor laid inside a room such as a clean room or an office room, and more particularly to a border portion structure thereof.

  15 and 16 are a plan view and a side sectional view showing the conventional border member 6 and the border portion structure 1 when the conventional border member 6 is installed. As shown in FIG. 16, the border member 6 is installed on the base floor surface 10 of the room where the free access floor 2 is laid, and between the standard panel 3 of the free access floor 2 and the wall 4 of the room. However, the border member 6 is installed not only in such a place but also in various places not shown in order to form a floor surface continuous with the standard panel 3.

  That is, the border member 6 cannot be provided with the standard panel 3 that is a fixed member, and is halfway formed on the side of the wall 4 or around a pillar (not shown) at a location away from the wall 4 in the room. It is installed to form a floor surface continuous with the standard panel 3 in a space.

  In the following description, a floor surface continuous to the standard panel 3 is formed by arranging a member other than the standard panel 3 such as the border member 6 around the wall 4 or around a pillar (not shown). The space is called a border part (see FIG. 16). The state in which the border member 6 is disposed adjacent to the standard panel 3 in the border portion is referred to as a border portion structure 1.

  The border member 6 is made of metal, has a thickness (dimension t in FIG. 16) in a direction substantially perpendicular to the base floor surface 10, and has a length and a width in a direction substantially parallel to the base floor surface 10. And a vertical plate portion 28 that is continuously bent and bent vertically from one end of the horizontal plate portion 26 on the wall 4 side to the base floor surface 10 side.

  In the border member 6, the horizontal plate portion 26 covers the base floor surface 10 above the border portion, and the end portion 26 a of the horizontal plate portion 26 opposite to the vertical plate portion 28 is the closest to the wall 4 of the standard panel 3. While being placed on the upper surface, the vertical plate portion 28 is disposed so as to protrude substantially vertically on the base floor surface 10.

  Due to the border member 6, the border portion has a large step in the height direction between the standard panel 3 and the base floor surface 10 (the dimension obtained by adding the thickness of the standard panel 3 to the height of the standard support legs 8. The floor surface of the free access floor 2 of the room is formed so as to extend from the standard panel 3 to the wall 4.

  On the other hand, the free access floor 2 has a structure in which the standard panel 3 is supported by the standard support legs 8. The standard support leg 8 includes a metal pipe member 12, and an upper cap 14 and a lower cap 16 made of synthetic resin for closing the upper end and the lower end of the pipe member 12. The upper cap 14 is formed with an upper end surface 18 that is substantially parallel to the base floor surface 10.

  FIG. 17 is a plan view of the standard support leg 8 showing only the standard support leg 8 shown in FIGS. As shown in the figure, the standard support leg 8 is formed so as to open on the upper end surface 18 of the upper cap 14 and can be engaged with four bent side plate portions 24 of the standard panel 3 described later. A groove 20 is provided.

  The four groove portions 20 of the standard support leg 8 are arranged in parallel with each other at regular intervals so that two of the four grooves 20 extend in one direction on the upper end surface 18, and are perpendicular to the two. The other two are arranged in parallel with each other at regular intervals so as to intersect. In each of these four groove portions 20, two combinations arranged in parallel with each other intersect each other at substantially the center in the length direction of each other. In the length direction of each groove portion 20, the length dimension from the intersecting position with the other groove portion 20 extending in the direction perpendicular to the length direction to the circumferential surface tangent of the upper cap 14 parallel to the length direction is defined. In FIG. 17, it is represented by L.

  FIG. 18 is a plan view of the standard panel 3 showing only the standard panel 3 in FIGS. The standard panel 3 is a fixed member, and as shown in the figure, the top plate portion 22 having a substantially square planar shape and the base floor surface 10 side (in FIG. 18, And a side plate portion 24 that is bent so as to have a certain height on the back side in the direction perpendicular to the paper surface.

  As shown in FIG. 15, the standard panel 3 is arranged in alignment in the vertical direction and the horizontal direction on the horizontal plane. The standard support legs 8 are provided at the corners of the four standard panels 3 except for those used to support the corners on the border part side of the standard panel 3 arranged adjacent to the border part. Are arranged at a position where they are gathered in one place, and each corner of the four standard panels 3 is supported from below.

Hereinafter, the best mode for carrying out the border structure according to the present invention will be specifically described with reference to the drawings.
FIGS. 1 to 5 are diagrams referred to for explaining the border part structure 32 according to the first embodiment of the present invention. The same parts as those in the prior art will be described using the same reference numerals, and overlapping description of the same configurations as those in the past will be omitted.

  As shown in FIGS. 1 and 2, the border portion structure 32 according to the present embodiment has a first border member 40, instead of the border member 6 according to the conventional border portion structure 1 (see FIGS. 15 and 16). 8A of border part support legs, the 2nd border member 36, the edge part member 34, and the sheet | seat member 41 are provided, and these have a structure installed in a border part.

  As shown in FIG. 3A, the border portion where the border portion structure 32 according to the present embodiment is installed has the standard support legs 8 at the side of the wall 4 before the border portion structure 32 is installed. As shown in FIG. 3B, a halfway space formed due to the fact that both the standard support legs 8 and the standard panel 3 cannot be arranged at the wall 4 as shown in FIG. ) And (b), the dimension M), and the space after removing the first standard panel 3 from such a halfway space side (the dimension S in FIGS. 3A and 3B). Is formed to a length that is added together.

  Further, as shown in FIG. 4, since the length M of the halfway space formed near the wall 4 is short, the groove 20 in the standard support leg 8 closest to the wall 4 from such a length M. When the length N obtained by subtracting the length p sandwiched between them is shorter than the length (b + f) obtained by adding the lengths b and f in FIG. As described above, the border portion is obtained by adding the halfway space of the length M and the space (dimension 2S in FIG. 4) from which the second standard panel 3 is removed from the halfway space side. It is formed to a length.

  As shown in FIGS. 1 and 2, the support legs 8 </ b> A in the border part of the border part structure 32 are arranged on the base floor surface 10 in the border part at regular intervals in the vertical direction in FIG. 1 of the border part. Is.

  The border-inner support legs 8A have the same structure as the standard support legs 8, but do not support the standard panel 3. From this point of view, the standard support legs 8 that support the standard panel 3 are supported. It will be distinguished from. Further, as shown in FIG. 2, the support legs arranged on the boundary line K between the border portion and the area where the standard panel 3 is arranged are distinguished from the other support legs 8 and 8A, particularly on the boundary line. It will be called the leg 8B.

  Further, as shown in FIG. 2, the end member 34 is bent substantially vertically from the one end portion of the floor plate portion 44 to the base floor surface 10 side and is continuously bent. And an end member hooking portion 48 formed by bending substantially vertically from the end of the floor plate portion 44 opposite to the hanging plate portion 46 to the base floor surface 10 side. is doing.

  As shown in FIG. 1, the end member 34 has a length that is almost twice the length of one side of the standard panel 3. 2, the floor plate portion 44 is placed on the upper end surface 18 of each border portion supporting leg 8A, and the end member latching portion 48 is a groove portion on the left side in FIG. 2 in each border portion supporting leg 8A. By being hooked by 20, it is supported by each border portion support leg 8A.

  Next, as shown in FIG. 2, the first border member 40 of the border portion structure 32 includes a first horizontal plate portion 54 provided substantially parallel to the base floor surface 10, and one of the first horizontal plate portions 54. The first vertical plate portion 56 that is continuously formed by bending vertically downward from the end portion, and whose front end portion is grounded to the base floor surface 10, and the first vertical plate portion 56 in the first horizontal plate portion 54 It has the 1st border latching | locking part 58 formed by bending substantially perpendicularly from the edge part on the opposite side to the base floor surface 10 side.

  As shown in FIGS. 1 and 2, the first border member 40 is configured such that both corners of the first horizontal plate portion 54 on the first border latching portion 58 side correspond to the upper end surfaces of the corresponding boundary support legs 8B. As shown in FIG. 2, the first border latching portion 58 is latched in the groove portion 20 on the left side in FIG.

  Further, a step 60 is formed in the first horizontal plate portion 54 of the first border member 40 at a midway position in the left-right direction in FIG. The step 60 is such that the first vertical plate portion 56 side is lower than the first border latching portion 58 side by the same height as the thickness of the second horizontal plate portion 50 in the second border member 36 described later. Is formed.

  As shown in FIG. 2, the second border member 36 includes a second horizontal plate portion 50 provided substantially parallel to the base floor surface 10, and one end portion of the second horizontal plate portion 50 from the base floor surface 10 side. The second border hooking portion 52 is formed by being bent substantially perpendicularly to each other.

  As shown in FIGS. 1 and 2, the second border member 36 is configured such that each of the corners on the second border latching portion 52 side of the second horizontal plate portion 50 has an upper end surface of the corresponding border portion supporting leg 8 </ b> A. As shown in FIG. 2, the second border latching portion 52 is latched in the groove portion 20 on the right side in FIG. It is supported by the leg 8A.

  Further, the second border member 36 has an end portion 50 a opposite to the second border latching portion 52 in the second horizontal plate portion 50 placed on the first horizontal plate portion 54 in the first border member 40. Thus, it can slide within the length range on the first vertical plate portion 56 side relative to the step 60.

  That is, in the border portion structure 32, as shown in FIG. 5A, the end portion 50a of the second horizontal plate portion 50 in the second border member 36 is different from the step difference of the first horizontal plate portion 54 in the first border member 40. As shown in FIG. 5 (b), the second border member 36 is integrated with the end portion member 34 and the border portion supporting legs 8A, and moves away from the step 60 (see FIG. 5B). It is possible to slide in the left direction in FIG.

As shown in FIG. 5C, the second border member 36 is a distance between the end portion 50 a of the second horizontal plate portion 50 and the step 60 of the first horizontal plate portion 54 in the first border member 40. d is slidable within the range from “0” to the same length as the arrangement interval S of the standard panel 3 (see FIG. 3). Thereby, as shown in FIGS. 5A to 5C, the border structure 32 has an overall length W ₁ within a range from the minimum length C ₁ to the maximum length (C ₁ + S). It can be adjusted.

The length of the entire adjustment range of the length W ₁ of the border portion structure 32, which are set to the same length as the length of the arrangement interval S of the standard panel 3, as shown in FIG. 5 (a), the border portion minimum length C ₁ of the structure 32, together is configured to include a slide length S of the second border member 36, in addition to, the end member 34 and the border portion in the supporting legs of such sliding length S It is configured to include a length b necessary for arranging 8A and the like, and a length f of the right side portion in the figure from the step 60. Therefore, the minimum length C ₁ of the border part structure 32 can be expressed as (C ₁ = b + S + f).

On the other hand, the minimum length C ₁ of this border section structure 32, FIG. 3 (a) and between the length M shown in (b), such a length M standard support legs 8 and the standard because it is halfway space can not be placed panels 3, always M <(S + b) <relationship C ₁ is established.

  For this reason, the border part structure 32 cannot be installed in such a halfway space indicated by the length M. However, by removing one standard panel 3 to form a border part, such a border part structure 32 cannot be installed. The border part structure 32 can be placed on the border part. Then, by adjusting the length of the border portion structure 32, a new floor surface can be formed over the entire length of the border portion (see FIG. 2).

Further, as shown in FIG. 4, since the length M is too short, the length M obtained by subtracting the length p sandwiched between the grooves 20 in the standard support leg 8 closest to the wall 4 from the length M. When the length N is shorter than the length (b + f) obtained by adding b and f shown in FIG. 5 (a), one sheet of the standard panel 3 with respect to the length N shown in FIG. The length (N + S) obtained by adding the length S of the arrangement interval of the minute is shorter than the minimum length C ₁ = (b + S + f) of the border portion structure 32. Therefore, the border can be obtained only by removing one standard panel 3. The partial structure 32 cannot be installed.

  However, in such a case, the border portion structure 32 can be placed by removing two standard panels 3 and forming a border portion. Although not shown, when the border part structure 32 is placed on the border part formed by removing two standard panels 3 as shown in FIG. 4, the border part structure 32 placed in this way is shown in FIG. By performing the length adjustment as shown in 5 (a) to (c), a new floor surface can be formed over the entire length of the border portion.

Further, by adjusting the length of the border portion structure 32, as shown in FIG. 5 (c), even if the length W _{1 is set} to the maximum length (C ₁ + S), the border Even if there is a case where the length of the part is too long and a new floor surface cannot be formed over the entire length of the border part, in such a case, the border part structure The length W _{1 of} 32 is temporarily shortened by the same length as the arrangement interval S of the standard panel 3 to return to the state shown in FIG. By arranging one standard panel 3 instead of shortening, the border portion can be newly shortened.

  Therefore, if the border portion is shortened by installing one standard panel 3, the length of the border portion structure 32 can be adjusted again for such a new border portion shortened. A new floor surface can be formed over the entire length of the new border portion thus shortened.

  Thus, the length of the adjustment range of the entire length of the border part structure 32 is the same as the length of the arrangement interval S of the standard panel 3, and the length of the border part is equal to the border part structure. In view of the fact that the length can be adjusted for each arrangement interval S of the standard panel 3 by removing or installing the standard panel 3 before the 32 is installed, the border part structure 32 has a border part of any length. It can be said that it is possible to cope with.

  In addition, as shown in FIGS. 1 and 2, the border portion structure 32 is installed by adjusting the overall length in the left-right direction in the drawing so as to correspond to the length in the same direction of the border portion. A synthetic resin sheet member 41 is placed between the step 60 in the first horizontal plate portion 54 of the first border member 40 and the second horizontal plate portion 50 of the second border member 36.

  The sheet member 41 is obtained by using a simple cutting tool such as a cutter knife from a material of a large sheet member 41 that has been previously prepared with a thickness substantially the same as the thickness of the second horizontal plate portion 50 of the second border member 36. It can be formed by cutting. The sheet member 41 may be attached to the first horizontal plate portion 54 with a double-sided tape or the like.

  According to the border part structure 32 according to the present embodiment, the overall length of the border part structure 32 is reduced by the slide adjustment of the second border member 36 with respect to the first horizontal plate part 54 of the first border member 40. Since it is possible to adjust the border portion structure 32, the border portion structure 32 can be installed in the border portion without cutting the horizontal plate portion of the metal border member as in the prior art. It can prevent that the efficiency of 32 installation work falls.

  Further, according to the border portion structure 32 according to the present embodiment, the sheet member 41 includes the step 60 in the first horizontal plate portion 54 of the first border member 40 and the second horizontal plate portion 50 of the second border member 36. It is possible to prevent two steps forming a recess on the floor formed by the first border member 40 and the second border member 36 from being placed between the first border member 40 and the second border member 36. .

  Further, according to the border part structure 32 according to the present embodiment, the first horizontal plate part 54 of the first border member 40 is not placed on the standard panel 3, so that it is on the floor surface of the free access floor 2. It is possible to prevent the step from being formed, and to prevent the arrangement shelf or the library placed on the step from being inclined.

  Further, according to the border part structure 32 according to the present embodiment, the adjustment range of the length is the same as the arrangement interval S of the standard panel 3 as shown in FIG. As shown in FIG. 5, regardless of the length of the border portion from the wall 4, a floor surface continuous to the standard panel 3 can be formed in the border portion without any gap.

Next, FIG. 6 to FIG. 14 are diagrams which are referred to for explaining the border section structure 62 according to the second embodiment of the present invention.
