[Technical field]

[0001] The present invention relates to a floor structure. [Background technology]

[0002] A known structure for installing a rack on a floor involves laying rails on the floor and fixing the rack to the rails (see, for example, Patent Document 1). The floor structure in Patent Document 1 has a height adjustment bolt provided at the bottom of the rail for fixing the rack, and the bottom of the height adjustment bolt is placed on the floor surface. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2001-255 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the floor structure of Patent Document 1, the load of the rack and rail is supported via height adjustment bolts, so there is a problem that the load of the rack and rail is locally concentrated on the floor slab. In particular, when the load of the rack is large, the concentrated load acting on the floor slab becomes large.

[0005] The present invention was invented in consideration of such problems, and has an object to provide a floor structure that supports loads such as racks and that can support the load by distributing it across the floor slab. [Means for solving the problem]

[0006] The present invention for solving the above problem provides a floor structure including a beam frame for supporting a load, a beam support member for supporting the beam frame, and an anchor member for fixing the beam support member to a floor slab. The beam support member includes an upper plate portion and side plate portions respectively hanging down from both ends of the upper plate portion in the width direction, and the side plate portions function as load support portions for transmitting the load of the load and the beam frame to the floor slab. According to the floor structure of the present invention, the load of the load object and the beam frame is transmitted to the floor slab via the side plate portion, so that the load can be distributed across the floor slab and local concentration of load on the floor slab can be suppressed.

[0007] In the floor structure of the present invention, the beam support is preferably made of an extruded material made of aluminum or an aluminum alloy. With this configuration, even if the beam support has a complex shape, it can be easily formed with high accuracy. Furthermore, the strength of the beam support can be ensured.

[0008] In the floor structure of the present invention, it is preferable that the lower end of the side plate has a lip portion extending horizontally. With such a configuration, the installation area of ​​the beam support material on the floor slab is increased, and the load can be further distributed.

[0009] In the floor structure of the present invention, it is preferable that the anchor member includes a support part connected to the upper plate part of the beam support member and a bottom plate part provided at the lower end of the support part, and the bottom plate part is placed and fixed on the floor slab. With this configuration, the anchor member can be fixed to the floor slab, and when a part of the load of the rack and rail is transmitted to the floor slab via the anchor member, it can be dispersed by the bottom plate part. In addition, when multiple anchor bolts are fixed to the bottom plate part, the stress acting on the anchor bolts is transmitted to the beam support member as a total holding force via the support part, so that it is possible to prevent the load from concentrating on a specific anchor bolt.

[0010] In the floor structure of the present invention, it is preferable that a plurality of anchor insertion holes are formed in the bottom plate portion. With such a configuration, anchor bolts for fixing the bottom plate portion to the floor slab can be installed while avoiding the positions of the reinforcing bars of the floor slab.

[0011] In the floor structure of the present invention, it is preferable that a beam cover material is provided on the side of the beam frame to cover the side surface of the beam frame. With such a configuration, the aesthetic appearance of the floor structure can be improved and the strength of the beam frame can be increased. Effect of the Invention

[0012] The floor structure of the present invention has the excellent effect of being able to distribute and support the load on the floor slab. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] A floor structure according to an embodiment of the present invention will be described in detail with reference to the attached drawings. As shown in Fig. 3, a floor structure 1 according to this embodiment is installed on a floor slab 2 and supports a load 3. The load 3 is, for example, a heavy item such as a server rack. In the following description, the front-rear, left-right, top-bottom directions are set for the convenience of explaining the floor structure according to this embodiment, and do not limit the configuration or usage state of the floor structure.

[0015] As shown in FIGS. 1 and 2, the floor structure 1 includes a beam frame 10, a beam support member 30, and an anchor member 50.

[0016] The beam frame 10 is a portion that supports the load 3 (see FIG. 3) and is made of an extruded profile material made of aluminum or an aluminum alloy. The extruded profile material has an extrusion direction in the front-to-rear direction. The beam frame 10 is a long member that extends in the front-to-rear direction. The beam frame 10 is a beam-shaped member that is supported by beam supports 30, 30... that are arranged at a predetermined interval in the front-to-rear direction. The beam frame 10 has a rectangular cross-section and includes an upper plate 11, a bottom plate 12, and side plates 13.

[0017] As shown in Figs. 5 to 8, an upper fixing groove 14 is formed in the upper plate 11. A rack fixing bracket 70 is fixed to the upper fixing groove 14. The upper fixing groove 14 is formed with a U-shaped cross section that opens upward and extends in the front-rear direction. On both sides in the width direction (left-right direction) of the upper end of the upper fixing groove 14, a locking portion 15 that protrudes inward is formed. A nut N1 is inserted into the upper fixing groove 14 (see Fig. 6). The two-face width of the nut N1 is smaller than the width dimension of the upper fixing groove 14, and the diagonal distance is larger than the width dimension of the upper fixing groove 14. The rack fixing bracket 70 is fixed to the beam frame 10 by tightening the bolt B1 extending from the rack fixing bracket 70 to the nut N1 and pulling and locking the nut N1 against the lower surfaces of the locking portions 15, 15. The upper fixing grooves 14 are formed in three rows, for example, and are arranged at both the left and right ends of the upper plate 11 and at the middle portion thereof. The rack fixing bracket 70 is disposed across two adjacent rows of upper fixing grooves 14, 14. This makes it possible to select either the left or right side of the upper plate 11 as the position where the rack fixing bracket 70 is disposed.

[0018] As shown in FIG. 4, the rack fixing bracket 70 is a member having a rectangular shape in a plan view. The upper surface of the rack fixing bracket 70 becomes the mounting surface of the server rack. Recesses 71 for installing bolts B1 are formed at the four corners of the rack fixing bracket 70. The heads of the bolts B1 are housed in the recesses 71 so that the bolts B1 do not protrude from the upper surface of the rack fixing bracket 70. The rack fixing bracket 70 is formed with grooves 72 extending in the left-right direction. The grooves 72 are provided with gripping parts 73 for gripping the legs of the server rack so that their positions can be adjusted in the left-right direction. The rack fixing bracket 70 is installed at positions corresponding to the four corners of the bottom surface of the server rack.

[0019] As shown in Figs. 6 and 7, the bottom plate 12 is formed with a lower fixing groove 16 for fixing the beam support member 30. The lower fixing groove 16 is formed with a gate-shaped cross section that opens downward. On both sides of the lower end of the lower fixing groove 16 in the width direction, a locking portion 17 that protrudes inward is formed. The head of a bolt B2 for fixing the beam support member 30 is inserted into the lower fixing groove 16. The bolt B2 is a hexagonal socket bolt, and a washer W is provided on the shaft side end of the head of the bolt B2 so as to be relatively rotatable. A jig insertion hole 21 (see Fig. 6) for inserting a jig for rotating the bolt B2 is formed in the bottom (upper part) of the lower fixing groove 16 above the installation position of the bolt B2 and in the upper plate 11 above it. The washer W has a rectangular shape, and its width in the left-right direction is smaller than the width dimension of the lower fixing groove 16, and its diagonal distance is larger than the width dimension of the lower fixing groove 16. The washer W is engaged with the upper surfaces of the engaging portions 17, 17. The shaft portion of the bolt B2 extends downward through between the engaging portions 17, 17, and extends further downward through a first bolt insertion hole 33 of the beam support member 30 described below. A jig is inserted through the jig insertion hole 21, and the bolt B2 is rotated to screw a nut N2 fixed to the beam support member 30 onto the lower end portion of the shaft portion. This fixes the beam support member 30 to the beam frame 10. The lower fixing grooves 16 are formed in, for example, two rows, and each row is disposed at a middle position of the upper fixing groove 14. The heads of the bolts B2 are inserted into the left and right lower fixing grooves 16, 16, respectively.

[0020] The side plate 13 is a portion that connects the widthwise end of the top plate 11 and the widthwise end of the bottom plate 12, and is formed like a wall that extends vertically. An engagement groove 18 is formed at the upper end of the side plate 13. The engagement groove 18 is formed with a U-shaped cross section that opens sideways toward the outside. An engagement portion 19 that protrudes inward is formed on both the upper and lower sides of the tip of the engagement groove 18. A hook portion 83 at the upper end of a beam cover material 80 described below is inserted into the engagement groove 18, and the hook portion 83 abuts against the inside of the upper engagement portion 19, thereby engaging the upper end of the beam cover material 80 to the beam frame 10.

[0021] A reinforcing diagonal member 20 is provided inside the beam frame 10. The diagonal member 20 is formed to span the upper fixing groove 14 and the lower fixing groove 16 that are adjacent to each other diagonally in the left-right direction.

[0022] As shown in Figs. 1 and 2, the beam support material 30 is a member that supports the beam frame 10, and is made of an extruded shape material made of aluminum or an aluminum alloy. The extruded shape material has a left-right direction as an extrusion direction, and the beam support material 30 extends in the left-right direction. The length of the beam support material 30 in the longitudinal direction (left-right direction) is greater than the length of the beam frame 10 in the width direction (left-right direction), and both left and right ends of the beam support material 30 protrude outward beyond both ends of the beam frame 10 in the width direction (see Fig. 1). The beam support material 30 is provided below the beam frame 10, and is arranged at a predetermined interval in the front-rear direction. The beam support material 30 has a gate-shaped cross section, and includes an upper plate portion 31 and a side plate portion 32.

[0023] The upper plate portion 31 is formed with a first bolt insertion hole 33, a second bolt insertion hole 34, and a third bolt insertion hole 35 (see FIG. 2(a)). The shaft portion of a bolt B2 for fixing the beam support material 30 to the beam frame 10 is inserted into the first bolt insertion hole 33. A plurality of first bolt insertion holes 33 (four in this embodiment) are provided at intervals in the front-to-rear direction and arranged in a line. Two linear rows of the first bolt insertion holes 33 are provided, and each is arranged at a position corresponding to the lower fixing groove 16 of the beam frame 10.

[0024] A bolt B3 constituting a support portion 51 of the anchor member 50 described later is inserted into the second bolt insertion hole 34. The second bolt insertion holes 34 are provided on both the left and right sides, and are formed outside the beam frame 10 in the left-right direction.

[0025] The third bolt insertion hole 35 is a bottomed hole. A shaft portion of a bolt B4 for fixing a beam cover material 80 described later to the beam support material 30 is inserted into the third bolt insertion hole 35. An internal thread is formed on the inner peripheral surface of the third bolt insertion hole 35. A plurality of third bolt insertion holes 35 (two in this embodiment) are formed at each of the left and right ends of the upper plate portion 31 at intervals in the front-rear direction.

[0026] 8 and 9, a downwardly protruding rib 36 is formed on the lower surface of upper plate portion 31. Rib ribs 36 extend in the left-right direction and are formed in two rows spaced apart in the front-rear direction. Rib ribs 36 are formed at positions that do not interfere with any of first bolt insertion hole 33, second bolt insertion hole 34, and third bolt insertion hole 35.

[0027] A nut holder 37 is attached to the lower surface of the upper plate portion 31 (see FIG. 8(b) and FIG. 9). The nut holder 37 is a member that holds the nut N2 into which the shaft portion of the bolt B2 is screwed, and is fixed to the inner surface of the beam support material 30. The nut holder 37 has a plurality of polygonal (hexagonal) holes 38 into which the nuts N2 can be fitted. A washer W2 is integrally formed on the upper portion of the nut N2. The nut N2 is inserted into the hole 38 from above the nut holder 37, and the washer W2 is engaged with the upper surface of the nut holder 37, so that the nut N2 is held in the nut holder 37 in an unrotatable state. The nut holder 37 is disposed below the first bolt insertion hole 33, and the first bolt insertion hole 33 and the hole 38 are disposed coaxially. The nut holder 37 is screwed to the protrusion 36 from below. A gap of the same height as the height of the protrusion 36 is created between the upper surface of the upper plate portion 31 excluding the protrusion 36 and the nut holder 37, and a washer W2 integrated with the nut N2 is placed in this gap.

[0028] As also shown in Figure 2, the side plate portions 32 are continuous with both ends of the upper plate portion 31 in the front-rear direction (width direction) and hang down downward. The side plate portions 32 are placed on the floor slab 2 and serve as load supporting portions that transmit the load of the load object 3 and the beam frame 10 to the floor slab. The side plate portions 32 are formed continuously over the entire length of the beam support material 30 in the extrusion direction. A lip portion 39 that extends horizontally is formed at the lower end of the side plate portion 32. The lip portion 39 protrudes toward the inside of the beam support material 30. The lower surface of the lip portion 39 abuts against the upper surface of the floor slab 2.

[0029] As shown in FIG. 2(a) and FIG. 6, the anchor member 50 is a member for fixing the beam support member 30 to the floor slab 2. The anchor member 50 includes a support portion 51 and a bottom plate portion 52. The support portion 51 is constituted by a bolt B3, and is erected at the center of gravity of the bottom plate portion 52. The bolt B3 is a fully threaded bolt. The upper end portion of the bolt B3 is inserted into the second bolt insertion hole 34 and protrudes above the upper plate portion 31. A nut N3 is attached to the base end portion (lower end portion) of the bolt B3, and a nut N3 and a washer are attached to the upper end portion of the bolt B3. The lower nut N3 is disposed at a height at which it abuts against the lower surface of the upper plate portion 31 of the beam support member 30, and the upper nut N3 and the washer are disposed above the upper plate portion 31. The anchor member 50 is fixed to the beam support material 30 by clamping the upper plate portion 31 of the beam support material 30 between the lower nut N3 and the upper nut N3.

[0030] The bottom plate portion 52 is a member placed on the floor slab 2 and is attached to the lower end of the support portion 51. As shown in FIG. 10, the bottom plate portion 52 is formed of a flat plate having a hexagonal shape in a plan view, and a plurality of anchor insertion holes 53 are formed. The anchor insertion holes 53 are arranged symmetrically around the fixing position of the support portion 51. For example, the center of the support portion 51 is one of the corners of a square, and the anchor insertion holes 53 are formed at the other three corners. The three anchor insertion holes 53 are also formed on the opposite side of the support portion 51. When fixing such a bottom plate portion 52, at least two anchor bolts B5 are inserted into the anchor insertion holes 53 and driven into the floor slab 2. The anchor insertion holes 53 are selected at positions that avoid the reinforcing bars of the floor slab 2. Basically, as shown in (a) to (c) of FIG. 11, the anchor insertion holes 53 are selected at positions symmetrical around the mounting position of the support portion 51. If the rebar cannot be avoided using anchor insertion holes 53 at symmetrical positions, two anchor insertion holes 53 that are not at symmetrical positions may be selected as shown in (d) and (e) of Fig. 11. In this case, one anchor insertion hole 53 is selected from each of the anchor insertion holes 53 on either side of the support portion 51. The bottom plate portion 52 is disposed outside the nut holder 37 in a bottom view (see Fig. 10). Since the bottom plate portion 52 is located lower than the nut holder 37, the bottom plate portion 52 may be rotated and disposed at a position overlapping the nut holder 37.

[0031] With the anchor member 50, beam support material 30, and beam frame 10 configured as above assembled, a beam cover material 80 is provided on the side of the beam frame 10. As shown in Fig. 1 and Fig. 6, the beam cover material 80 is a member that covers the side of the beam frame 10 and both ends of the beam support material 30 protruding to the left and right from the beam frame 10. As also shown in Fig. 7, the beam cover material 80 is made of an extruded material made of aluminum or an aluminum alloy, and includes a beam frame cover portion 81 and a beam support material cover portion 82.

[0032] The beam frame cover portion 81 is a portion that covers the side surface of the beam frame 10, and is inclined so as to become lower from the upper end of the side plate 13 toward the outside. The upper end of the support portion 51 of the anchor member 50 that protrudes from the upper surface of the beam support material 30 is accommodated inside the beam frame cover portion 81. A hook portion 83 and a locking protrusion 84 are formed at the tip of the beam frame cover portion 81. The hook portion 83 is a portion that is inserted into the locking groove 18 of the side plate 13, and is formed rising upward from the tip of the beam frame cover portion 81. The locking protrusion 84 is a portion that abuts against the outside of the locking portion 19 of the locking groove 18, and is formed adjacent to the hook portion 83 and protruding downward. The hook portion 83 abuts against the upper locking portion 19 from the inside of the locking groove 18, and the locking protrusion 84 abuts against the lower locking portion 19 from the outside, thereby locking the beam cover material 80 to the beam frame 10. A screw fastening portion 85 for fixing the lid body 90 described below is formed on the inside (lower surface side) of the beam frame cover portion 81. The screw fastening portion 85 is formed in two places, at the upper end and lower end of the beam frame cover portion 81, and is screwed into by the shank of a screw V driven from the lid body 90 side.

[0033] The beam support cover portion 82 is a portion that covers the end of the beam support material 30, and is integrally molded continuously with the outer side of the beam frame cover portion 81. The beam support cover portion 82 includes a planar portion 86 and a wall portion 87. The planar portion 86 is a portion that is placed on the end of the upper plate portion 31 of the beam support material 30, and spreads horizontally. The planar portion 86 is formed with a bolt insertion hole 88 through which a bolt B4 for fixing the beam cover material 80 to the beam support material 30 is inserted. The bolt insertion hole 88 is formed coaxially with the third bolt insertion hole 35 of the beam support material 30. The bolt B4 is inserted from above into the bolt insertion hole 88 and attached to the third bolt insertion hole 35, thereby fixing the beam cover material 80 to the beam support material 30.

[0034] As shown in Fig. 1, a lid 90 is provided at both the front and rear ends of the beam frame 10 and the beam cover material 80 to cover the end faces. The lid 90 has an upper edge shape that follows the upper surface of the beam frame 10 and the beam cover material 80 on both the left and right sides, and its bottom edge is formed in a straight line. The lid 90 has a screw hole 91 formed in a position corresponding to the screw fastening portion 85 of the beam cover material 80. By attaching the lid 90, the aesthetic appearance of the floor structure 1 can be improved and dirt and dust can be prevented from entering the interior of the beam frame 10.

[0035] According to the floor structure 1 of this embodiment, the load of the load object 3 and the beam frame 10 is transmitted to the floor slab 2 via the side plate portion 32 of the beam support material 30, so that the load can be distributed to the floor slab 2 and localized concentration of the load on the floor slab 2 can be suppressed. Furthermore, since a lip portion 39 is formed at the lower end of the side plate portion 32, the contact area of ​​the beam support material 30 with the floor slab 2 becomes larger, and the load can be further distributed.

[0036] Incidentally, in the case of an earthquake, the load in the vertical direction is the weight of the server rack added to the load in the downward direction. In contrast, the load in the upward direction is smaller because the load in the earthquake is offset by the weight of the server rack. In the floor structure 1 of this embodiment, when a large downward load is applied, the side plate portion 32 of the beam support material 30 contacts the floor slab 2 to transmit the load, so that the beam support material 30 is not subjected to a bending force, and the thickness can be minimized to increase the strength rationally. In addition, when a load is applied in the upward direction, the beam support material 30 moves away from the floor slab 2 and pulls only the anchor member 50, so that the beam support material 30 can be given a holding force that is the sum of the pull-out resistance of the multiple anchor bolts B5 fixed to the anchor member 50 and cast into the floor slab 2. This makes it possible to reduce the number and strength of the anchor bolts B5.

[0037] Since the beam frame 10 and the beam support member 30 are made of extruded aluminum or aluminum alloy material, they can be easily formed with high precision even if the beam frame 10 and the beam support member 30 have complex shapes. Furthermore, the strength of the beam frame 10 and the beam support member 30 can be ensured.

[0038] In addition, since the anchor member 50 comprises a support portion 51 and a bottom plate portion 52, and the bottom plate portion 52 is placed on and fixed to the floor slab 2, the anchor member 50 can be easily fixed to the floor slab 2, and when part of the load of the load object 3 and the beam frame 10 is transmitted to the floor slab 2 via the anchor member 50, the load can be distributed by the bottom plate portion 52. Incidentally, as a configuration for fixing a rail to a concrete slab, a conventional technique is known in which a reinforcing plate is laid perpendicularly to the underside of the rail and fixed to the concrete slab via multiple anchor bolts (see JP 2021-59905 A (hereinafter referred to as the "Reference Document")). In the fixing structure of this Reference Document, the anchor bolts are fixed directly to the reinforcing plate, so there is a problem that the load is concentrated on a specific anchor bolt close to the rail. According to the anchor member 50 of this embodiment, the stress acting on the multiple anchor bolts B5 fixed to the bottom plate portion 52 is transmitted to the beam support material 30 as a total holding force via the support portion 51, so that it is possible to prevent the load from being concentrated on a specific anchor bolt.

[0039] Furthermore, since a plurality of anchor insertion holes 53 are formed in the bottom plate portion 52, the anchor bolts B5 can be installed while avoiding the positions of the reinforcing bars of the floor slab 2.

[0040] The beam cover material 80 is provided on the side of the beam frame 10, which improves the aesthetic appearance of the floor structure 1 and increases the strength of the beam frame 10. In addition, the beam cover material 80 also covers both the left and right ends of the beam support material 30, which prevents dirt and dust from entering the inside of the beam support material 30.

[0041] Although the embodiment for carrying out the present invention has been described above, the present invention is not limited to the above embodiment, and appropriate design changes are possible within the scope of the present invention. For example, in the above embodiment, the bottom plate portion 52 of the anchor member 50 is hexagonal in shape, but this is not limited thereto. As shown in FIG. 12, the bottom plate portion 52a of the anchor member 50a may be square in plan view. In this case, it is preferable that the anchor insertion holes 53 are formed at the four corners and the middle portions of each side of the square. The other configurations are the same as those of the above embodiment, so the same reference numerals are used and the description is omitted.

[0042] With the bottom plate portion 52a configured in this way, the anchor bolts can be positioned in a well-balanced manner around the support portion 51 while avoiding the reinforcing bars of the floor slab. In addition, as shown in Fig. 12(b), by rotating the bottom plate portion 52a, the options for the installation position of the anchor bolts can be increased. Note that the bottom plate portion 52a is located lower than the nut holder 37, so that it will not interfere with the nut holder 37 even if the bottom plate portion 52 is rotated.

[0043] In the above embodiment, the lip portion 39 at the lower end of the side plate portion 32 is formed so as to extend inward, but this is not limited to this. The lip portion may be formed so as to extend outward from the side plate portion 32, or may be formed so as to extend both inward and outward. [Explanation of symbols]
