Definitions

  • the embodiment discussed herein is related to a method of forming a floor structure and an underfloor space and, more particularly, to a technique of partitioning the underfloor space.
  • a free access floor (also referred to as “raised floor” or “free access”) formed by laying floor panels (free access panels) in a bridged manner over supporting legs regularly arranged in a raised manner on a base floor face.
  • a floor structure in which the underfloor space of the free access floor is partitioned by arranging a partition plate between two supporting legs (refer to, e.g., the following Patent Document 1).
  • the upper section of the partition plate is fixed onto a pedestal for placing a panel in a support leg, and the lower section of the partition plate is fastened onto an L-shaped angle material fixed and mounted onto a base floor face or the base plate of the support leg.
  • a plate supporter is set up to the L-shaped angle material in a height adjustable manner and the lower section of the partition plate is fixed onto the plate supporter.
  • the structure for fixing the partitioning plate is complicated.
  • the complicated structure in the above mentioned prior art makes it difficult to change the direction of the flow of air such as cooling air flowing in the underfloor space. Therefore, a heat problem causing a system to be unstable, such as heat accumulation (hot spot generated in an area, such as air intake faces of the IT devices, where the temperature should be kept low), easily occurs.
  • a free access floor formed by free access panels arranged above a base floor includes a specific panel that is one of the free access panels and has a slit, and a partitioning plate inserted into the slit, so as to hang down from a surface of the specific panel and orient airflow in a space between the base floor and the free access panels.
  • a free access floor according to the embodiment can be applied to a floor of a data center where the number or layout of racks accommodating servers and the like is frequently changed.
  • FIG. 1 is a plan view illustrating a part of the free access floor
  • FIG. 2 is a side view illustrating the part of the free access floor of FIG. 1 .
  • a plurality of free access panels 1 a are arranged in a plane to form a free access floor 1.
  • the free access floor 1 is supported by a plurality of pillars 3 raised on a base floor 2.
  • a space is formed between the free access floor 1 and the base floor 2.
  • the free access panels 1 a each have a rectangular shape, and the pillars 3 each support the area where the vertexes of the four free access panels 1 a contact each other.
  • the pillars 3 each support the vertexes of the free access panels 1 a at substantially the center of its support surface.
  • Some free access panels (specific panels) among the plurality of free access panels 1 a have a slit 5.
  • the slit 5 is formed in any one or plurality of free access panels (specific panels) 1a among the plurality of free access panels 1a.
  • FIG. 3 is a cross-sectional side view taken along the II-II line of FIG. 1 in a state where a partitioning plate is set in a free access panel.
  • a partitioning plate 6 that orients airflow in the space between the base floor 2 and free access floor 1 is inserted into a given slit 5 among the plurality of slits 5, as illustrated in FIG. 3 .
  • the partitioning plate 6 determines the direction of the flow of air flowing in the space.
  • the partitioning plate 6 is detachably provided so as to hang down from the surface of the free access panel 1 a.
  • the slit 5 is, in the free access panel 1 a in which the slit 5 is formed, formed to extend between the pillars 3 that support the free access panels 1a on the base floor 2. Insertion of the partitioning plate 6 into the slit 5 allows the space in one direction of the free access panel 1 a to be partitioned by the pillars 3 and the partitioning plate 6.
  • FIG. 4 is a cross-sectional side view taken along the II-II line of FIG. 1 in a state where the partitioning plate is not set in the free access panel.
  • a closing plate 7 is fitted so as to close the slit 5. More specifically, a step 5a is formed on the upper surface side of the free access panel 1 a, and the closing plate 7 is fitted to the step 5a to thereby close the slit 5 while making the surfaces of the free access panel 1 a constituting the free access floor 1 flush with each other.
  • a support portion 6a formed at the upper edge of the partitioning plate 6 is stopped by the step portion 5a, whereby the partitioning plate 6 is supported by the free access panel 1 a.
  • the partitioning plate 6 illustrated in FIG. 3 is a plate member made of e.g., wood or plastic and is formed integrally with the supporting portion 6a.
  • one slit 5 is formed in one free access panel 1a.
  • a plurality of slits 5 may be formed in one free access panel 1a for receiving the insertion of the partitioning plate 6.
  • the plurality of slits 5 are formed so as to extend along the respective sides of the rectangular free access panel 1 a perpendicularly or in parallel to each other.
  • a partitioning plate 16 illustrated in FIG. 6 is formed of a flexible member.
  • the partitioning plate 16 of FIG. 6 has a configuration in which a partitioning portion 16b formed of a flexible member such as a flexible fabric having a sufficient size and shape to partition the space under the panel is fixed to a support portion 16a, and a plurality of weights 16c are fitted to the lower edge of the partitioning portion 16b.
  • the plurality of weights 16c are attached to a lower edge of the partitioning portion 16b.
  • the fabric may be a chemical fiber (nylon, polyester, etc.) or vinyl chloride sheet.
  • the weight 16c may be a metal material (iron, etc.) or a plastic resin material.
  • a flexible partitioning plate 16 allows the hanging amount (length of the partitioning portion 16 in the height direction) of the partitioning plate 16 to be adjusted so as to, e.g., prevent the upper end portion (support portion 16a) of the partitioning plate 16 from protruding from the free access floor 1 even when an obstacle 9 exists on the base floor 2, thereby easily partitioning the underfloor space. Further, even when the level of the base floor 2 is raised as illustrated in FIG. 7B , the use of the flexible partitioning plate 16 allows easy partitioning of the underfloor space.
  • the partitioning plate may be fixed to the support portion as follows. That is, the upper edge 16d of the flexible member 16b constituting the partitioning portion 16b is adhered to the support portion by adhesives as illustrated in FIG. 8 or the upper edge 16d of the flexible member 16b is mechanically fixed to the support portion by tacks, pins, or screws 11 as illustrated in FIG. 9 .
  • FIG. 10 illustrates an example of the free access floor 1 according to the present embodiment.
  • the plurality of free access panels 1 a each in which the partitioning plate 6 (or partitioning plate 16) is provided are combined to form a flow path R of cooling air in the underfloor space. Accordingly, the cooling air emitted from an air conditioner 20 is not made to flow in a location where cooling is unnecessary but is made to effectively flow only in the flow path R formed by the partitioning plates 6, thereby reducing power consumption required for air conditioning. Further, the configuration of the flow path R can easily be changed by selecting whether to set or not the partitioning plate 6 to the slit of the free access panel 1 a or selecting an appropriate slit to which the partitioning plate 6 is set in terms of its extending direction.
  • the partitioning plate 6 orients airflow in the space between the base floor 2 and the free access panels 1 a. Accordingly, a partitioning method is provided.
  • the partitioning method includes inserting the partitioning plate 6 into the slit 5, so that the partitioning plate 6 hangs down from a surface of the free access panel 1 a, and orienting airflow in the space by the partitioning plate 6.
  • the cooling air toward an area where cooling is unnecessary can easily be blocked during, e.g., the initial phase of the system operation in a data center, enabling a reduction of power cost of an air conditioner.
  • the free access floor 1 can easily be partitioned in accordance with an analysis area that is cut out from the free access floor 1 for modeling of air-condition simulation, increasing accuracy of analysis made by the air-condition simulation.
