Description
~3~33Z~
This invention relates to a readjustable floor system which, in a so-called intelligent building inherently and essentially necessitating freely readjustable distribu-tion of power, communication and transmission cables for connection to office-automating machines and tools and telephones, for example, permits amply free distribution of such cables.
In recent years, various office-automating machines and tools which are intended to i~prove o~fice work and data transmission work in operational efficiency have been ~inding their way into an increasing number of officesO This t.rend has been urging the desirability of enabling power, communication and transmission cables of various sorts for connection to such office-automating machines and tools to be Preely distributed in a perfectly concealed condition instead of being randomly laid out conspicuously on the floor.
Under these circumstances, the floor duct method which consists in burying d~cts under office floors and the ~lat cable method which comprises preparing cables of ~lattened cross sections and distributing these cables under ordinary tile carpets have been proposed.
In the case of the floor duct method, because ~he lines of distribution and the volume of cables for distribution are predetermined by the positions of buried ducts and the diameters of cables selected to be laid out, it naturally follows that the freedom of dis-tribution of cables has its own limit. The most serious one o~ the problems encountered by this method resides in the fact that this method is incapable of flexibly coping with expansion and relocation of the office-automating machines and tools already installed.
The flat cable method is capable of flexiblY coping ~ith the e~pansion and relocation of already distributed cables as compared with the floor duct method. It ne~ertheless poses as a new problem the disadvantage that the cables to be used are required to be specially molded in flattened cross sections and, .
~ 3~ ~ 3~
whenever the already distributed cables are increased or r010cated, the tile carpets already placed are required to be peeled off the floor bed and then replaced.
One object of this invention is to provide a readjustable floor system which enables cables o-f various sorts -to be freely distributed ~ith an extremely simple structure.
Another object of this invention is to provide a readJustable floor sYstem which is capable o-f very flexibly coping with expansion and relocation of already distribu-ted cables of various sorts with a very simple structure.
To accomplish the objects described above, according to this invention, there is provided a readiustable ~loor system comprising unit members of an approximately U-shaped cross section each composed of a pair o~ ~loor member-supporting ioists disposed parallelly on a floor surface in an opposed relation -to each other across a fixed interval and a bottom plate laid to interconnect the lower parts of the pair of floor me~ber-supporting joists, the unit members definin~ -therein a space for distribution of cables and pipes, a plurality of antistatic sheets each having opposite ends fastened to the pair of floor member-supporting joists for vertically partitioning the space, and unit floor boards detachably mounted one each on top of the unit members~
According to -this invention, there is also provided a readjustable floor system comprising unit members of an approximately U-shaped cross section each composed of a pair of floor member-supportin~ joists disposed parallelly on a floor surface in an opposed relation to each other across a fi~ed interval and a bottom plate laid to interconnect the lower parts of the pair of floor member-supporting ioists, the unit members defining therein a space for distribution of cables and pipes, a plurality of antistatic sheets each having oposite ends fastened to the pair of floor member-supporting joists for vertically partitioning the space, each of the antistatic sheets ~L3~3~
concurrently serving as a heat-transfer sheet and having a groove-shaped receptacle, unit floor boards detachably mounted one each on top of the unit members, and a plurality of -thermal medium-circulating pipes each distributed across the groove-shaped receptacle of the heat-transfer sheet.
In either o~ the constructions mentioned above, this invention contemplates additionally having dewproofing members, one of which is interposed between the bottom plates of the uni-t members and the floor surface.
The above and other obiects, characteristic features and advantages of the present invention will become more apparent to those skilled in the art as the disclosure is made in the following description o-f preferred embodiments of the invention, as illustra-ted in the accompanying drawings, in ~hich:-Figure 1 is a perspective view illustrating in a separatedstate a unit member and a unit floor board used for an embodiment of this inventionr Figure 2 is a plan vie~ of the essential part illustrating the unit me~bers in a ioined state.

This invention contemplates a readjustable floor system ~hich is produced by forming unit members of an appro~i~atelY
U-shaped cross section each composed of a pair of floor member-supportin~ joists disposed parallellY on a ~loor surface in a opposed relation to each other across a ~i~ed interval and a bottom plate laid to interconnec-t the lower parts of the pair of ~3~3~
_4-floor member-supporting joists, defining a space for distribution of cables and pipes inside the unit members, vertically partitioning the space through antistatic sheets, and de-tachably mounting unit floor boards one each on top of the unit members.
This invention further contemplates a floor system ~hich is produced by forming unit members of an approximately U-shaPed cross section each composed of a pair of floor member-supporting joists disposed parallelly on a floor surface in an opposed relation to each other across a fi~ed interval and a bottom plate laid to interconnect the lower parts of the pair of floor member-supporting ioists, defining a space for distribution of cables and pipes inside the unit members, vertically partitioning the space through heat-transfer sheets concurrently serving as antistatic sheets, distributing thermal medium-circulating pipes across groove-shaped receptacles formed in the heat-transfer sheetsS and detachably mounting unit floor boards one each on top of the unit members.
In either of the constructions embodyin~ this invention as mentioned above, the present invention contemplates addi-tionally having dewproofing members, one of which is interposed bet~een the bottom plates of the unit members and the floor surface.
In the present invention, ~hen a dewproofing sheet is stretched out on the floor surface and the unit members are laid end to end and side by side on the dewproofing sheet, the spaces for distribution of cables and pipes which are defined inside the individual unit members are joined continuously so as to form desired lines for distribution of cables and piPeS. Then, the cables and pipes of various sorts for connection to the office automating machines and tools can be freely distributed through the continued ducts formed of ioined spaces. Thereafter, the unit floor boards are mounted one each directly above the pairs of floor member-supporting ioists joined end to end and side by side. Thus7 a f~oor structure having the cables of various sorts easily and freely distributed therein can be assembled ~ith ease.
~3tP3~
Particularly in the case where high-voltage cables and lo~-vol-tage cables are distributed together, generation of noise poses itself as a problem. Th~s invention precludes this problem by adopting the construction in which the spaces are partitioned ~ith the antistatic sheets so that the high-voltage cables and the low-voltage cables may be distributed in a separated fashion via the antistatic sheets.
Moreover, in the construction of a floor structure in accordance with this invention, when the sPaces -for distribution of cables and pipes are vertically partitioned with heat-transfer sheets serving concurrently as antistatic sheets and th0rmal medium-circulating pipes are distributed across the groove-shaped receptacles formed in the heat-transfer shee-ts, continuous ducts formed of the joined spaces can be utiliæed for ready installation of a floor-warming unit. An ideal floor warming can be attained by circulating a suitable thermal medium such as hot water -through the thermal medium-circulating pipes.
The possible occurrence of dew by the temperature difference causable in floor ~armin~ can be effectively prevented by the interposition of a dewproofing shee-t between the bottom plates of the unit members and the floor surface~
Now, the present invention will be described in detail below with reference to the embodiments illustrated in the accompanying drawings.
The basic structure of the readiustable floor system according to the present invention is obtained, as illustrated in Figures 1 and 2, by forming uni-t members 3 of an appro~imately U-~haped cross section each composed of a pair of floor member-supporting joists 1 disposed parallelly on a concrete floor surface of an intelligent building in an opposed relation to each other across a fixed interval and a bottom plate 2 laid to interconnect the lower parts of the pair of floor me~ber-supporting joists 1, thereby enabling the unit members 3 to be laid continuously end to end and side by side on -the concrete ~34~3~
floor surface, and detachablY mounting uni-t floor boards 6 on0 each on top o~ the floor member-supportin~ joists 1, thereby defining spaces 4 for distribution of cables and pipes inside the unit members 3~
When the unit members 3 of the U-shaped cross section are continuously laid end to end and side by side on the concrete floor surface, the spaces 4 defined for distribution of cables and pipes inside the individual unit members 3 are naturally continued in the longitudinal direction. A plurality of depressed through parts 5 are formed in each of the supportin~
ioists 1 as illustrated in Figure 1 or Fi~ure 2. The spaces 4, therefore, are also continued in the lateral direction across the through parts 5.
The pair of floor member-supporting ioists 1 each have a plurality of holes 7 with a lateral opening and an upper opening du~ symmetically in the portions thereof not occupied by the depressed through parts 5. When the unit members 3 are continuously laid end to end and side by side, therefore, connecting members 8 can be fitted into abutting holes 7 in -the adjoining supporting ioists 1 for the purpose of mutually fastening the unit members 3 with ample fastness particularly in the lateral direction.
Desirably, the floor member-suPporting ioists 1 are long rectan~ular pieces of wood, eoncrete, synthetic resin or metallic substance prepared in various lengths. Depending on the area9 shape, etc. of the concrete floor surface given to be covered with the floor system, therefore, the unit members 3 of the optimum length may be offered.
The unit floor boards 6 are made of stratiform wood such a~
plywood, stone, concrete panel having core ~ires buried -therein, synthetic resin panel or metallic plate. TheY are invariably prepared in a si~e suitable for them to be continuouslY laid one each on the uPper surfaces of the pair of supporting ioists 1.
It is necessary that they be produced in size and ~eight iust :~3~33~L
proper for them to be easily removed from the upper surfaces of the supporting Joists 1 ~ith the aid of a known suction means or a handle formed at a suitable position -thereo-f (not sho~n specifically). It is likewise necessary that the unit floor boards 6, when mounted in such a manner that the lateral parts thereof ride directlY on the supporting joists 1, ~anifest strength large enough to ~ithstand normal load exerted upon the central part thereof.
In the present embodiment~ the floor produced bY assemblin~
the floor system acquires a structure fit concurrently for a floor~warming mechanism. To be specific, the floor system of this invention permits the floor of a given room to be ~arm by disposing inside the spaces 4 combination antis-tatic and heat-transfer sheets 9 of coper each having the central part thereof depressed and the opposite lateral ends 9a thereof fastened to the upper surfaces of the pair of floor member-supporting joists 1, and disposing thermal medium-circulating pipes 11 one each in grooved-shaped receptacles 10 formed in the central part of the hea-t-transfer sheets 9 as illustrated in FIG. 3 and FIG. 4, and effecting forced circulatlon of a suitable thermal medium such as hot ~ater through the pipes ll. In Figure 4, reference numeral 12 designates a heat insulator suitably packed between the heat-transfer sheets 9 and the bottom plates 2.
Furthermore, in the present embodi~ent, dewproofing sheets 14a and 14b are respectivelY interposed betw~en the bottom plates 2 laid continuously side by side and the surface of a concrete floor 13 and between the heat insulators 12 and the heat-transfer sheets 9 as illustrated in Fi~ures 3 and 4 so as to effectiYely prevent the occurrence of dew due to the temperature difference ascribable to the floor warming. This preclusion of dew formation keeps the cables C distributed in the floor from other~ise possible adverse effects of ~ater condensateO
In producing a floor structure in an intelligent building by copiously using the unit members 3 and the unit floor boards 6 J33~
constructed as described above, first the surface 13 of a concrete floor is entirely covered with the dewproofing sheet 14a and -then a multiplicity of uni-t members 3 are laid on the dewproo~ing sheet 14a continuously end to end and side by side.
As a result, the spaces 4 defined for distribution of cables and pipes inside the indi~idual unit me~bers 3 are continued in the longitudinal direction and, at the same ti~e, they are con-tinued in the lateral direction across the through parts 5 so as to give birth to a multiplicity o~ continuous distribution lines.
After the assembly has proceeded to this point, the heat-transfer plates 9 are set in place with the opposite lat~ral ends 9a thereof fastened to the upper sur~aces of the floor ~ember-supporting ioists 1 of the unit members 3 and the heat medium-circulating pipes 11 are laid one each in the groov~-shaped receptacles 10 formed in the heat-transfer plates 9. Thus, the floor-warming mechanism can be easily incorporated in the floor structure by making effective use of the continuous spaces 4~
The floor warming of a room can be accomplished by completing the floor structure as described above and then circulating a suitable thermal medium such as hot water supplied from a boiler etc. through the heat medium-circulating pipes 11.
When the spaces 4 ~hich have been continued longitudinally and laterally and made to incorPOrate therein a floor-~arming mechanism are sui-tably selected, they permit connection of cables C of various sor-ts to various office-automatin~ machines and tools to be freely distributed in the longitudinal and lateral directions. After the free distribution by the use of these continued spaces 4 has been completed, the floor structure aimed at can be immediately completed by moun-ting the unit floor boards ~ sequentiallY and continuously in such a manner that they will ride one each directly on the supporting joists 1 ~hich have the opposite lateral ends 9a of the heat-transfer plates 9 fastened thereto.
GenerallY in the distribution of cables C of various sorts, ~3~
g thare is a possibilitY of noise being generated ~here hi~h-vol-tage cables and lo~-volta~e cables are laid out clo5ely to~ether. In the light of this possibility, the present invention contemplates vertically partitioning the spaces 4 with the combination antis-tatic and heat-transfer sheets 9 of copper as described above, thereby allowing high-voltage cables and lo~-voltage cables to be distributed separately above and belou the heat-transfer plates 9. Thus, the present invention is perfectly free from such perennial problems as inevitable generation of noise.
Moreover, in the present embodiment, there is employed a structure for ef-fectively precluding the ~ormation of de~
ascribable to the temperature difference inherent in floor warming by interposing the dewproofing sheets 14a and 14b respectively between the bottom plates 2 and the surface of the concrete floor 13 and between the heat insulators 12 and the heat-transfer plates 9. This embodiment, therefore, completely precludes the possibility of water condensate înflic-ting adverse effects on the cables C.
When the cables C which have been freely distributed as described above are obliged to be redistributed on account of expansion or relocation of office-automatin~ machines and tools and telephones, for e~ample, the required redis-tribution of the cables C can be very flexiblY and easily accomplished ~ithout requiring any repair work by re~oving pertinent unit floor boards 6 from the upper ~urfaces of the supporting joists 1 to expose the continued spaces 4 and then redistributin~ the cables C by again utilizin~ the continued spaces 40 While in this embodiment each of the supportlng jois-ts 1 of the unit member 3 is a long rectangular piece havin~ the through parts 5 inserted in the lateral sides thereof and also having the holes 7, this is by no means limitative. OptionallY, each of the supporting ioists 1 may comprise a pluralitY of short pieces la provided with holes 7 and spaced at fixed intervals. In this :3L3~i~3~
case, cables C can also be distributed and branched in the longitudinal and lateral directions as illustrated in Figure ~.
The embodiment has been also described as causing the uni-t members 3 to be laid out on the surface of the concrete floor 13.
Optionally, this èmbodiment maY be modified to produce a resilient floor structure bY causing shoc~-absorbing means 15 such as springs or rubber members to underlay the supporting joists 1 o~ the unit members 3. Even in this modification, it is per~issible to have a dewproofing sheet 14a interposed between the surface of the concrete floor 13 and the shock-absorbing means 15 and another dewproofing sheet 14b interposed similarl~
on the upper side of the bottom plates 2.
Furthermore, the embodiment has been described as having the thermal medium-circulating pipes 11 for ~loor warming distributed throu~h the heat-transfer plates 9. This particular setup is not critical to this invention. Op-tionally, pipes of the sorts suitable for connection to facilities for supply and discharge of water and facilities for fire prevention maY be distributed in the floor structure of this embodiment.
In accordance with the readiustable floor system contemplated by the present invention, desired lines for distribution of cables and pipes are formed by covering the floor surface with the dewproofing sheet and laying the unit members continuously end to end and side by side on the dewproofin~ sheet, thereby allowin~ the spaces defined for distribution o~ cables and pipes inside the individual unit members -to continue into one another. Thereafter, the cables and pipes freely distribu-ted along the aforementioned lines can be completely concealed by mounting the unit floor boards sequentially and continuously on the pairs of floor member-supportin~ ioists.
Particularly in the distribution of cables, the spaces are partitioned with antistatic sheets so that high-voltage cables and low-voltage cables may be separately dis-tributed through the antistatic sheets. Thus, noise which is possibly generated ~here ` ~ 3~3 ~ ~ ~
high-vol-tage cables and lo~-voltage cables are distrîbuted closely together can be precluded infalllibly.
Where expansion or relocation of the existing office-automating machines and tools necessitates redistribution of the existing cables, the floor structure of the present embodiment can flexibly cope with the redistribution. Thus, the floor system contemplated by the present invention is highly e-ffective in furnishing an intelligent building wi-th an updated floor.
In accordance with this invention, the floor structure can incorporate therein a floor-warming mechanism by vertically partitioning the spaces for the distribution of cables and pipes with the combination antistatic and heat-transfer sheets and distributing the thermal medium-circulating pipes in the groove-shaped receptacles formed in the heat-transfer sheets by makin~
effective use of the continued spaces. Also from this point of view, this invention enjoys very high economic utility.
Moreover, since the dewproofing sheet is interposed bvetween the bottom plates of the unit members and the floor surface9 the formation of dew ascribable to the tempera-ture difference ~hich is inherent in floor warmin~ can be effectively precluded.
This invention relates to a readjustable floor system which, in a so-called intelligent building inherently and essentially necessitating freely readjustable distribu-tion of power, communication and transmission cables for connection to office-automating machines and tools and telephones, for example, permits amply free distribution of such cables.

Now, the present invention will be described in detail below with reference to the embodiments illustrated in the accompanying drawings.
The basic structure of the readiustable floor system according to the present invention is obtained, as illustrated in Figures 1 and 2, by forming uni-t members 3 of an appro~imately U-~haped cross section each composed of a pair of floor member-supporting joists 1 disposed parallelly on a concrete floor surface of an intelligent building in an opposed relation to each other across a fixed interval and a bottom plate 2 laid to interconnect the lower parts of the pair of floor me~ber-supporting joists 1, thereby enabling the unit members 3 to be laid continuously end to end and side by side on -the concrete ~34~3~
floor surface, and detachablY mounting uni-t floor boards 6 on0 each on top o~ the floor member-supportin~ joists 1, thereby defining spaces 4 for distribution of cables and pipes inside the unit members 3~
When the unit members 3 of the U-shaped cross section are continuously laid end to end and side by side on the concrete floor surface, the spaces 4 defined for distribution of cables and pipes inside the individual unit members 3 are naturally continued in the longitudinal direction. A plurality of depressed through parts 5 are formed in each of the supportin~

The pair of floor member-supporting ioists 1 each have a plurality of holes 7 with a lateral opening and an upper opening du~ symmetically in the portions thereof not occupied by the depressed through parts 5.

In producing a floor structure in an intelligent building by copiously using the unit members 3 and the unit floor boards 6 J33~
constructed as described above, first the surface 13 of a concrete floor is entirely covered with the dewproofing sheet 14a and -then a multiplicity of uni-t members 3 are laid on the dewproo~ing sheet 14a continuously end to end and side by side.
As a result, the spaces 4 defined for distribution of cables and pipes inside the indi~idual unit me~bers 3 are continued in the longitudinal direction and, at the same ti~e, they are con-tinued in the lateral direction across the through parts 5 so as to give birth to a multiplicity o~ continuous distribution lines.
After the assembly has proceeded to this point, the heat-transfer plates 9 are set in place with the opposite lat~ral ends 9a thereof fastened to the upper sur~aces of the floor ~ember-supporting ioists 1 of the unit members 3 and the heat medium-circulating pipes 11 are laid one each in the groov~-shaped receptacles 10 formed in the heat-transfer plates 9. Thus, the floor-warming mechanism can be easily incorporated in the floor structure by making effective use of the continuous spaces 4~
The floor warming of a room can be accomplished by completing the floor structure as described above and then circulating a suitable thermal medium such as hot water supplied from a boiler etc. through the heat medium-circulating pipes 11.
When the spaces 4 ~hich have been continued longitudinally and laterally and made to incorPOrate therein a floor-~arming mechanism are sui-tably selected, they permit connection of cables C of various sor-ts to various office-automatin~ machines and tools to be freely distributed in the longitudinal and lateral directions. After the free distribution by the use of these continued spaces 4 has been completed, the floor structure aimed at can be immediately completed by moun-ting the unit floor boards ~ sequentiallY and continuously in such a manner that they will ride one each directly on the supporting joists 1 ~hich have the opposite lateral ends 9a of the heat-transfer plates 9 fastened thereto.
GenerallY in the distribution of cables C of various sorts, ~3~
g thare is a possibilitY of noise being generated ~here hi~h-vol-tage cables and lo~-volta~e cables are laid out clo5ely to~ether. In the light of this possibility, the present invention contemplates vertically partitioning the spaces 4 with the combination antis-tatic and heat-transfer sheets 9 of copper as described above, thereby allowing high-voltage cables and lo~-voltage cables to be distributed separately above and belou the heat-transfer plates 9. Thus, the present invention is perfectly free from such perennial problems as inevitable generation of noise.
Moreover, in the present embodiment, there is employed a structure for ef-fectively precluding the ~ormation of de~
ascribable to the temperature difference inherent in floor warming by interposing the dewproofing sheets 14a and 14b respectively between the bottom plates 2 and the surface of the concrete floor 13 and between the heat insulators 12 and the heat-transfer plates 9. This embodiment, therefore, completely precludes the possibility of water condensate înflic-ting adverse effects on the cables C.
When the cables C which have been freely distributed as described above are obliged to be redistributed on account of expansion or relocation of office-automatin~ machines and tools and telephones, for e~ample, the required redis-tribution of the cables C can be very flexiblY and easily accomplished ~ithout requiring any repair work by re~oving pertinent unit floor boards 6 from the upper ~urfaces of the supporting joists 1 to expose the continued spaces 4 and then redistributin~ the cables C by again utilizin~ the continued spaces 40 While in this embodiment each of the supportlng jois-ts 1 of the unit member 3 is a long rectangular piece havin~ the through parts 5 inserted in the lateral sides thereof and also having the holes 7, this is by no means limitative. OptionallY, each of the supporting ioists 1 may comprise a pluralitY of short pieces la provided with holes 7 and spaced at fixed intervals. In this :3L3~i~3~
case, cables C can also be distributed and branched in the longitudinal and lateral directions as illustrated in Figure ~.
The embodiment has been also described as causing the uni-t members 3 to be laid out on the surface of the concrete floor 13.
Optionally, this èmbodiment maY be modified to produce a resilient floor structure bY causing shoc~-absorbing means 15 such as springs or rubber members to underlay the supporting joists 1 o~ the unit members 3. Even in this modification, it is per~issible to have a dewproofing sheet 14a interposed between the surface of the concrete floor 13 and the shock-absorbing means 15 and another dewproofing sheet 14b interposed similarl~
on the upper side of the bottom plates 2.
Furthermore, the embodiment has been described as having the thermal medium-circulating pipes 11 for ~loor warming distributed throu~h the heat-transfer plates 9. This particular setup is not critical to this invention. Op-tionally, pipes of the sorts suitable for connection to facilities for supply and discharge of water and facilities for fire prevention maY be distributed in the floor structure of this embodiment.
In accordance with the readiustable floor system contemplated by the present invention, desired lines for distribution of cables and pipes are formed by covering the floor surface with the dewproofing sheet and laying the unit members continuously end to end and side by side on the dewproofin~ sheet, thereby allowin~ the spaces defined for distribution o~ cables and pipes inside the individual unit members -to continue into one another. Thereafter, the cables and pipes freely distribu-ted along the aforementioned lines can be completely concealed by mounting the unit floor boards sequentially and continuously on the pairs of floor member-supportin~ ioists.
Particularly in the distribution of cables, the spaces are partitioned with antistatic sheets so that high-voltage cables and low-voltage cables may be separately dis-tributed through the antistatic sheets. Thus, noise which is possibly generated ~here ` ~ 3~3 ~ ~ ~
high-vol-tage cables and lo~-voltage cables are distrîbuted closely together can be precluded infalllibly.
Where expansion or relocation of the existing office-automating machines and tools necessitates redistribution of the existing cables, the floor structure of the present embodiment can flexibly cope with the redistribution. Thus, the floor system contemplated by the present invention is highly e-ffective in furnishing an intelligent building wi-th an updated floor.
In accordance with this invention, the floor structure can incorporate therein a floor-warming mechanism by vertically partitioning the spaces for the distribution of cables and pipes with the combination antistatic and heat-transfer sheets and distributing the thermal medium-circulating pipes in the groove-shaped receptacles formed in the heat-transfer sheets by makin~
effective use of the continued spaces. Also from this point of view, this invention enjoys very high economic utility.
Moreover, since the dewproofing sheet is interposed bvetween the bottom plates of the unit members and the floor surface9 the formation of dew ascribable to the tempera-ture difference ~hich is inherent in floor warmin~ can be effectively precluded.
