  As shown in FIGS. 5 to 7, the covering portion 21 includes an upper plate portion 21a (see FIG. 4) having a substantially rectangular flat upper surface, and three sides of the upper plate portion 21a (up and down direction in FIG. 6). 6 is provided with a side plate portion 21b formed so as to extend in a substantially vertical downward direction (a lower side direction in FIG. 7) from three side portions excluding one side portion on the left side in FIG.

  As shown in FIG. 7, the two side plate portions 21b extending in the left-right direction in FIG. 6 are each formed with two notches 21d that open downward in FIG. 7 and have a rectangular opening shape. ing.

  The two notches 21 d are along the outer peripheral surface of the side plate portion 4 b (see FIG. 4) that forms the side surface of the rail member 4 and the outer peripheral surface of the upper plate portion 4 c (see FIG. 4) that forms the upper surface of the rail member 4. Each is formed in such a shape (see FIG. 3).

  Thus, since the notch 21d which fits the rail member 4 is formed in the two side plate portions 21b orthogonal to the rail member 4 extending in the vertical direction in FIG. 2, the lower end surface of the cover member 20 is the floor panel 3. The cover member 20 can be covered on the rail member 4 so as to be in contact with the upper surface 3a (see FIG. 3).

  Moreover, as shown in FIG. 7, between the two notch parts 21d in the side-plate part 21b, it has the width | variety substantially the same as the opening width of the opening part of the rail member 4 (length dimension of the left-right direction in FIG. 7). The insertion part 21c (protrusion part) is formed (refer FIG. 3).

  As shown in FIG. 3, the insertion portion 21 c is inserted into the rail through the opening of the rail member 4 when the cover member 20 is put on the rail member 4, and the lower end thereof is the bottom plate of the rail member 4. It is formed so as to contact the upper surface of the portion 4a (see FIG. 4).

  The length dimension of the insertion part 21c in the vertical direction in FIG. 7 is greater than the length dimension in the vertical direction in FIG. 7 of the other part of the side plate part 21b (the part where the insertion part 21c and the notch part 21d are not formed). Also, it is formed shorter by the height of the bottom plate portion 4a (see FIG. 4) of the rail member 4.

  As described above, the length of the insertion portion 21c in the vertical direction in FIG. 7 is formed to be shorter by the height of the bottom plate portion 4a (see FIG. 4) of the rail member 4, so that the lower end surface of the cover member 20 is formed. The cover member 20 can be covered on the rail member 4 so as to be in contact with the upper surface 3a of the floor panel 3 (see FIG. 3).

  Moreover, as shown in FIG. 8, the insertion part 21c is arrange | positioned in the back | inner side for a while in the up-down direction in the figure rather than the side-plate part 21b which forms the outer peripheral surface of the cover member 20. As shown in FIG. That is, the upper insertion portion 21c in the drawing is formed slightly lower in the drawing than the upper side plate portion 21b in the drawing, and the lower insertion portion 21c in the drawing is the lower side plate portion 21b in the drawing. It is formed slightly above the figure (see FIG. 9).

  As described above, the insertion portion 21c is disposed slightly deeper in the vertical direction in FIG. 8 than the side plate portion 21b, so that the upper plate portion is removed when the cover member 20 is removed from the upper side (see FIG. 11). A finger can be hooked on a portion of the lower surface of 21a on the outer side in the vertical direction in FIG. 8 with respect to the insertion portion 21c (see FIG. 9).

  Moreover, the coating | coated part 21 is provided with the some rib 21e integrally formed in the back surface side of the upper-plate part 21a, as shown in FIG.8, FIG.9. As shown in FIG. 10, the rib 21e protrudes from the back surface side of the upper plate portion 21a in the lower floor direction (lower direction in FIG. 10) and has a length in both vertical and horizontal directions (up and down direction and left and right direction in FIG. 8). It is formed in a lattice shape so as to extend.

  The covering portion 21 is formed with such a plurality of ribs 21e, so that the strength thereof is improved and can withstand the load of equipment such as the server rack 10 (see FIG. 12).

  However, as shown in FIG. 8, the rib 21e is not formed in the position corresponding to the notch part 21d of the left-right direction in FIG. 8 in the back surface of the upper board part 21a (refer FIG. 10).

  Thus, when the rail member 4 is fitted into the notch 21d, the rib 21e that collides with the rail member 4 is not formed, so that the lower end surface of the cover member 20 contacts the upper surface 3a of the floor panel 3. As described above, the cover member 20 can be covered with the rail member 4.

  Moreover, as shown in FIG. 10, the rib 21e formed in the position corresponding to the insertion part 21c of the left-right direction in FIG. 8 in the back surface of the upper board part 21a is more than the rib 21e formed in the other position. The length in the vertical direction in FIG. 10 is shortened by the height of the bottom plate portion 4a (see FIG. 4) of the rail member 4.

  As described above, the length in the vertical direction in FIG. 10 of the rib 21e (see FIG. 4) inserted into the rail of the rail member 4 is the length in the vertical direction in FIG. 10 of the rib 21e formed at another position. The cover member 20 is shorter than the height dimension by the height of the bottom plate portion 4a (see FIG. 4) of the rail member 4, so that the lower end surface of the cover member 20 contacts the upper surface 3a of the floor panel 3. Can be put on the rail member 4 (see FIG. 3).

A side plate portion 22b extending substantially vertically downward from one side portion and having a substantially triangular (see FIG. 7) side surface is provided.

  As shown in FIG. 10, the upper plate portion 22 a of the inclined portion 22 is gently inclined diagonally downward to the left in FIG. 10 from the left end portion in FIG. 10 of the upper plate portion 21 a of the covering portion 21 by the height of the cover member 20. It is formed to be inclined.

  As described above, the inclined portion 22 is formed so as to fill a step between the rail member 4 and the upper surface 3a of the floor panel 3 so as to be a gently inclined surface (see FIG. 3).

  In addition, as shown in FIGS. 8 and 9, the inclined portion 22 includes a plurality of ribs 22e formed integrally on the back surface side of the upper plate portion 22a. The ribs 22e protrude from the back surface side of the upper plate portion 22a in the down-floor direction (lower direction in FIG. 10) and are formed in a lattice shape so that the length extends in both the vertical and horizontal directions (vertical direction and horizontal direction in FIG. 8). Has been.

  By forming such a plurality of ribs 22e, the inclined portion 22 is improved in strength and can withstand the load of equipment such as the server rack 10 (see FIG. 12).

  Here, the floor panel 3 in which the cover member 20 according to the present embodiment is used will be described. As shown in FIG. 4, the floor panel 3 includes a panel main body portion 16, a tile 17 attached to the upper surface of the panel body portion 16, and a rail member 4 fixed to the upper surface of the tile 17.

  The panel body 16 is a die-cast product using an aluminum alloy as its material, and includes a flat plate portion 16a that forms the upper surface thereof, and a plurality of ribs 16b that are integrally formed on the back surface side of the flat plate portion 16a. (See FIG. 4).

  Each of the plurality of ribs 16b of the panel body 16 protrudes from the back surface side of the flat plate portion 16a in the lower floor direction (the lower side direction in FIG. 4) and extends in both the vertical and horizontal directions along the horizontal plane of the flat plate portion 16a. Thus, it is formed in a lattice shape. The panel main body 16 is formed with such a plurality of ribs 16b so that the strength thereof is improved.

  Further, a tile 17 such as a vinyl chloride P tile or an HPL (High Pressure Laminate) tile is attached to the upper surface side of the flat plate portion 16 a of the panel main body portion 16.

  The rail member 4 is made of steel or the like, for example, aluminum extruded material, and has a C-shaped cross section perpendicular to the length direction (see FIG. 4). It is fixed to the upper surface of the tile 17 with the opening facing upward (upper side in the figure) (a state where the C-shape is rotated 90 degrees counterclockwise).

  As shown in FIG. 4, the bottom plate portion 4a on the opposite side of the opening in the rail member 4 penetrates in the plate thickness direction, and its opening area becomes smaller as it goes downward in FIG. A plurality of through-holes 4d formed with inclined inner peripheral surfaces are formed at predetermined intervals in the length direction of the rail member 4 (vertical direction in FIG. 2).

  Then, as shown in FIG. 4, the male screw portion 19b of the flat bolt 19 is inserted into the through hole 4d of the bottom plate portion 4a, and the upper surface of the head 19a of the flat bolt 19 is higher than the upper surface of the bottom plate portion 4a. So as not to protrude into the through hole 4d of the bottom plate portion 4a.

  Further, as shown in FIG. 3, among the plurality of ribs 16b of the panel body 16, the rib 16b having the largest length projecting from the back surface side of the flat plate portion 16a in the down floor direction (downward direction in FIG. 3). A plate member 15 having an inverted U-shaped cross section perpendicular to the length direction is arranged at the tip portion so that the upper plate portion 15a (see FIG. 4) on the opposite side to the opening portion is in contact.

  Since the plate member 15 has an inverted U-shaped cross section perpendicular to the length direction (see FIG. 4), the upper plate portion 15a is located upward as compared with the case where the plate member 15 is formed in a flat plate shape. Strength when pulled is improved.

  The plate member 15 is formed so as to have substantially the same length as the rail member 4, and the length direction of the rail member 4 (see FIG. 2) on the lower side in the vertical direction of the rail member 4 (see FIG. 4). (Middle up and down direction).

  Further, as shown in FIG. 4, the upper plate portion 15 a of the plate member 15 penetrates in the plate thickness direction (vertical direction in the drawing) at a position corresponding to the through hole 4 d of the bottom plate portion 4 a of the rail member 4. A female screw hole 15b is formed.

  Further, the flat plate portion 16 a of the panel main body portion 16 and the tile 17 are each formed with a through hole that communicates with the through hole 4 d of the bottom plate portion 4 a of the rail member 4. And as shown in FIG. 4, the male screw of the countersunk | bolt bolt 19 which has penetrated the through-hole 4d of the baseplate part 4a of the rail member 4, each through-hole of the flat plate part 16a, and the tile 17, and protrudes below in the figure. The tip of the portion 19 b is screwed into the female screw hole 15 b of the plate member 15.

  Therefore, when the rail member 4 tries to float upward, the inclined inner peripheral surface of the through hole 4d of the bottom plate portion 4a of the rail member 4 engages with the lower surface of the head portion 19a of the countersunk bolt 19. The upper surface of the upper plate portion 15a of the plate member 15 screwed to the tip of the male screw portion 19b of the countersunk bolt 19 is engaged with the lower surface of the rib 16b of the panel main body portion 16. For this reason, the rail member 4 is being fixed to the panel main-body part 16 so that it may not float up.

  As described above, since the upper plate portion 21a of the covering portion 21 of the cover member 20 covers the opening portion that opens above the rail member 4 (see FIGS. 3 and 4), the server rack 10 (see FIG. 12), the caster of the server rack 10 and the wheel of the carriage carrying the server rack 10 can be prevented from being loosely fitted into the opening of the rail member 4.

  Further, since the inclined portion 22 of the cover member 20 fills the step between the rail member 4 and the upper surface 3a of the floor panel 3 to form an inclined surface (see FIGS. 3 and 4), the server in the data center 1 is provided. When carrying in the rack 10 (refer FIG. 12), the caster of the server rack 10 and the wheel of the trolley | bogie which carries the server rack 10 can get over the rail member 4 smoothly.

  In addition, as shown in FIG. 2, the two cover members 20 adjacent in the left-right direction in the drawing are arranged so that the respective covering portions 21 are in contact with each other to form a continuous upper surface. For this reason, the caster of the server rack 10 and the wheel of the carriage carrying the server rack 10 can smoothly pass between the two rail members 4.

  Therefore, when the cover member 20 according to the present embodiment is used, the rail member 4 fixed to the floor panel 3 can be prevented from becoming an obstacle when equipment is carried into the data center 1.

  When using the rail member 4, as shown in FIG. 11, the cover member 20 is removed from the rail member 4, and then the slide member 7 is arranged in the rail of the rail member 4 as shown in FIG. 14. As described above, the server rack 10 and the floor panel 3 are connected via the fixing bolts 6.

  In addition, this invention is not limited only to the said embodiment, If it is in the range which can achieve the objective of this invention, a various change of a cover member is possible.

  For example, in the cover member 20 according to the embodiment, as shown in FIG. 7, the insertion portion 21 c is formed in the side plate portion 21 b of the covering portion 21, but the opening portion of the rail member 4 is the upper plate portion 21 a. If it is covered with (refer FIG. 4), the insertion part 21c does not need to be formed.

  Further, in the cover member 20 according to the embodiment, as shown in FIG. 10, ribs 21 e are formed on the back surface side of the upper plate portion 21 a of the covering portion 21, and on the back surface side of the upper plate portion 22 a of the inclined portion 22. Although the rib 22e is formed, the ribs 21e and 22e may not be formed.

  Further, as shown in FIG. 1, the cover member 20 according to the embodiment covers the opening of the rail member 4 fixed to the floor panel 3, and includes the rail member 4 and the upper surface 3 a of the floor panel 3. Although it was used to fill the steps between them, it need not be limited to the floor panel 3.

  Therefore, even if the cover member 20 is used to cover the opening of the rail member 4 fixed to the gantry (double floor member) and to fill the step between the rail member 4 and the upper surface of the gantry. Good.
