Description

[Technical Field]

[0001] The present invention relates to a floor structure for fixing equipment such as a computer on a floor. [Background technology]

[0002] Because computers and other equipment are sensitive to dust and vibrations and generate a lot of heat, they are often installed together in air-conditioned computer rooms or clean rooms. In such cases, each piece of equipment must be securely fixed to the floor or other surface to prevent it from falling over in the event of an earthquake or other disaster.

[0003] To accommodate the large amount of wiring and air conditioning required in these equipment rooms, a free access floor is typically installed at a specified height above the slab floor. The floor panels that make up the free access floor are placed on supports fixed to the slab floor, leaving space below the floor panels. This space is used to route wiring and allow air to circulate.

[0004] Various methods for fixing devices on such free access floors have been proposed (for example, Patent Documents 1 and 2). [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 54-80619 [Patent Document 2] Japanese Patent Application Laid-Open No. 2005-42411 Summary of the Invention [Problem to be solved by the invention]

[0006] However, securing space above the slab floor, as with conventional free access floors, requires installing free access panels throughout the room, resulting in a lot of waste. On the other hand, it is sometimes possible to route wiring along the walls and ceiling. In such cases, a lower-floor installation method for equipment is required, rather than installing it on the free access floor as in the past.

[0007] However, with the method of fixing the equipment directly to the slab floor, it is necessary to carry in and install the equipment before carrying out work such as driving anchors for fixing it in. As mentioned above, because the equipment is vulnerable to vibration and dust, it is not desirable to carry out work such as driving anchors into the slab floor after the equipment has been carried in.

[0008] Furthermore, even if the anchor positions are measured in advance and the equipment can be brought in after the anchors have been installed, if only some of the equipment is subsequently replaced, the anchors must be re-installed according to the size of the new equipment, which raises concerns about the impact on other equipment.

[0009] The present invention has been made in view of the above problems, and has an object to provide an equipment fixing floor structure that allows equipment to be installed on a low floor. [Means for solving the problem]

[0010] In order to achieve the above-mentioned object, the present invention provides a floor structure for fixing equipment to which equipment can be fixed, in which a rail member to which the equipment can be fixed is fixed to the upper surface of a floor, and another rail member is also fixed to the upper surface of the floor in a direction perpendicular to the longitudinal direction of the rail member, and the rail member has a pair of locking claws protruding upward and a bottom portion formed on the lower end side of the locking claws and connecting the pair of locking claws, and the bottom portion has portions protruding on both sides of the locking claws. The rail member is installed in a recess formed in the floor, concrete is poured around the rail member in the recess, and the upper surface of the rail member, the upper surface of the concrete poured around the rail member, and the upper surface of the floor other than the recess are approximately flush with each other. The floor structure for fixing equipment is characterized by the above.

[0011] The rail members may be arranged in parallel rows.

[0013] According to the present invention, rail members to which equipment can be fixed are fixed to the upper surface of the floor, allowing equipment to be installed at a low position. Furthermore, since rail members and the like only need to be placed in the area in the room where the equipment will be installed, there is less wasted space compared to placing support members or panels to secure space on the floor. Furthermore, since rail members to which equipment can be fixed are used, the fixing position can be easily changed depending on the size of the equipment. [Effects of the Invention]

[0015] According to the present invention, it is possible to provide an equipment fixing floor structure that allows equipment to be installed on a low floor. [Brief explanation of the drawings]

[0017] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

[0018] (First embodiment) Fig. 1 is a perspective view showing an equipment fixing floor structure 1 according to a first embodiment of the present invention. Fig. 2 is a plan view of the equipment fixing floor structure 1. Fig. 3(a) is a cross-sectional view taken along line AA in Fig. 2, and Fig. 3(b) is an enlarged view of part B in Fig. 3(a).

[0019] The equipment fixing floor structure 1 is mainly composed of rail members 3, plate-like members 5, anchor bolts 7, etc. The equipment fixing floor structure 1 is installed on a floor 9 such as a slab floor, and equipment (not shown) is installed and fixed above it.

[0020] 1 and 2, the plate-like member 5 is a substantially rectangular member. The plate-like member 5 is fixed to the upper surface of the floor 9 by, for example, anchor bolts 7 installed at the four corners.

[0021] It is not necessary to place anchor bolts 7 at all four corners of the plate-shaped member 5. For example, it is sufficient that the vicinity of two or more of the four corners of the plate-shaped member 5 are fixed with anchor bolts 7. The plate-shaped member 5 may also be fixed to the floor 9 by adhesive. The fixing method is selected depending on the construction conditions, etc.

[0022] The rail members 3 are capable of fixing devices to the rail members 3, and are fixed to the upper surface of the plate-shaped member 5. In this embodiment, the rail members 3 are arranged in two parallel rows. Each row is made up of three rail members 3. The rail members 3 are also arranged parallel to the long side direction of the plate-shaped member 5.

[0023] The rail members 3 may be arranged in three or more rows. Each row may be made up of one or more rail members 3. Furthermore, the rail members 3 do not have to be arranged only in parallel directions, but additional rail members 3 may be arranged in perpendicular directions. The arrangement of the rail members 3 is determined appropriately depending on the dimensions of the equipment to be fixed, etc.

[0024] As shown in FIG. 3(b), the rail member 3 has a pair of locking claws 4a that protrude upward, and a bottom portion 4b that is formed on the lower end side of the locking claws 4a and connects the pair of locking claws 4a. A bolt 11 is installed in the bottom portion 4b of the rail member 3. A hole 10 is formed in the plate-shaped member 5 at a position corresponding to the bolt 11. The rail member 3 is fixed to the upper surface of the plate-shaped member 5 by fixing the bolt 11 in the hole 10. The bolts 11 are installed at least near both ends of each rail member 3.

[0025] As described above, in the equipment fixing floor structure 1, the plate-like member 5, on whose upper surface the rail member 3 capable of fixing equipment is fixed, is fixed to the upper surface of the floor 9 via the plate-like member 5.

[0026] Next, a method for installing equipment using the equipment fixing floor structure 1 will be described. First, the rail member 3 is fixed to the upper surface of the plate-like member 5. As described above, the rail member 3 is fixed to the plate-like member 5 by fastening the bolts 11 into the female-threaded holes 10. The work of fixing the rail member 3 to the plate-like member 5 may be performed in the room where the equipment will be installed, or may be performed in advance at another location such as a factory. If the rail member 3 is fixed to the plate-like member 5 in advance, the amount of work done indoors can be reduced.

[0027] Next, the plate-like member 5 is placed in a predetermined position on the upper surface of the indoor floor 9. Then, anchor bolts 7 are driven into the four corners of the plate-like member 5 to fix the plate-like member 5 to the floor 9. Alternatively, the plate-like member 5 is fixed by adhesive bonding to the floor 9. In this way, the equipment fixing floor structure 1 is constructed.

[0028] After the equipment fixing floor structure 1 is constructed, the equipment is carried in and fixed onto the rail members 3. The equipment can be fixed to the rail members 3 with bolts or the like. This completes the installation of the equipment.

[0029] As described above, according to the first embodiment, unlike conventional free access floors, no space needs to be secured on the floor, and the equipment can be installed at a height from the floor 9 that is approximately the sum of the thickness of the plate-like members 5 and the height of the rail members 3. This allows the equipment to be installed on a low floor.

[0030] Furthermore, when installing equipment, the equipment can be fixed to the rail member 3 with bolts or the like, eliminating the need to drive anchors each time the equipment is installed. This makes installation easy and does not generate dust during installation. Furthermore, when replacing equipment, the rail member 3 can be adapted to equipment of different sizes within the installation range. Note that by forming holes 10 in advance at predetermined positions in the plate-like member 5, the position of the rail member 3 can also be changed. For example, holes 10 can be formed in multiple rows in advance so that the spacing between the rail members 3 can be changed, and the arrangement of the rail members 3 can be changed depending on the size of the equipment.

[0031] In the first embodiment, the plate-shaped member 5 to which the rail members 3 are fixed is fixed to the floor 9, so the positions of the multiple rail members 3 are determined simultaneously by determining the position of the plate-shaped member 5 relative to the floor 9. Therefore, compared to when the rail members 3 are fixed directly to the floor 9 without using the plate-shaped member 5, the rail members 3 can be easily fixed in accurate positions.

[0032] In the first embodiment, the rail member 3 and the plate-shaped member 5 are fixed together by the bolts 11, but the fixing method is not limited to this. Fig. 4(a) is a diagram showing another fixing method for the rail member 3. In the example shown in Fig. 4(a), the rail member 3 and the plate-shaped member 5 are fixed together by a welded portion 13. The welded portion 13 is formed between the side surface of the locking claw 4a of the rail member 3 and the upper surface of the plate-shaped member 5. The welded portion 13 is formed over the entire length of the rail member 3.

[0033] Furthermore, the configuration of the rail member 3 is not limited to the one described above. Figures 4(b) and (c) are diagrams showing another rail member 3a. The rail member 3a differs in configuration from the rail member 3 in that the bottom portion 4b connecting the pair of locking claws 4a protrudes on both sides of the locking claws 4a. The rail member 3a can be fixed to the plate-like member 5 using the protruding portions of the bottom portion 4b.

[0034] In the example shown in FIG. 4(b), the rail member 3a and the plate-shaped member 5 are fixed together by a weld 13. The weld 13 is formed between the side surface of the bottom 4b of the rail member 3a and the upper surface of the plate-shaped member 5. The weld 13 is formed over the entire length of the rail member 3a. As shown in FIG. 4(b), forming the weld 13 on the protruding portion of the bottom 4b improves workability and also reduces the effect of welding heat on the locking claws 4a.

[0035] In the example shown in FIG. 4(c), bolts 11a are installed in the portions of the bottom 4b of the rail member 3a that protrude on both sides of the locking claws 4a. Holes 10a are formed in the plate-shaped member 5 at positions corresponding to the bolts 11a. The rail member 3a is fixed to the upper surface of the plate-shaped member 5 by fastening the bolts 11a in the holes 10a. By installing the bolts 11a in the protruding portions of the bottom 4b as shown in FIG. 4(c), it is not necessary to insert a tool or the like into the narrow space between the pair of locking claws 4a, and therefore the rail member 3a can be easily fixed to the plate-shaped member 5.

[0036] (Second embodiment) Fig. 5(a) is a diagram showing a vertical cross section of an equipment fixing floor structure 1a according to a second embodiment of the present invention. Fig. 5(b) is an enlarged view of part C in Fig. 5(a), and Fig. 5(c) is a cross section taken along line DD in Fig. 5(b). In the following description, components that perform the same functions as those in the equipment fixing floor structure 1 are given the same reference numerals as in Figs. 1 to 3, and redundant description will be omitted.

[0037] The equipment fixing floor structure 1a shown in Figure 5(a) differs in configuration from the equipment fixing floor structure 1 of the first embodiment mainly in that rail members 3 are installed in recesses 15 formed in the floor 9. In the following description, the rail members 3 and 3a are assumed to be interchangeable.

[0038] The equipment fixing floor structure 1a is mainly composed of rail members 3, plate-like members 5, anchor bolts 7, concrete 17, etc. The equipment fixing floor structure 1a is installed using recesses 15 formed on the upper surface of a floor 9, such as a slab floor, and equipment (not shown) is installed and fixed above it.

[0039] The recess 15 is formed on the upper surface side of the floor 9. The recess 15 is sized to include the area where the rail member 3 is to be installed when the floor 9 is viewed from above, and to allow the plate-like member 5 to which the rail member 3 is fixed to be laid on the bottom surface.

[0040] The plate-like member 5 is placed on the bottom surface of the recess 15. The plate-like member 5 is fixed to the bottom surface of the recess 15 by anchor bolts 7 or by adhesive. The bottom surface of the recess 15 is the upper surface of the floor 9 at the location where the recess 15 is formed. In the equipment fixing floor structure 1a, the rail member 3 to which the equipment can be fixed is fixed via the plate-like member 5 to the upper surface of the floor 9 at the location where the recess 15 is formed.

[0041] Here, the upper surface of the floor 9 in the area where the recess 15 is formed is lower than the upper surface of the floor 9 in areas other than the recess 15 by the sum of the thickness of the plate-like member 5 and the height of the rail member 3. Therefore, in the equipment fixing floor structure 1a, the upper surface of the rail member 3 and the upper surface of the floor 9 in areas other than the recess 15 are substantially flush with each other.

[0042] 5(c), sealing members 19 are arranged on both end surfaces of the rail member 3 so as to cover the entire end surfaces. Concrete 17 is poured around the rail member 3 in the recess 15.

[0043] Next, a method for installing equipment using the equipment fixing floor structure 1a will be described. First, in the room or other location where the equipment will be installed, the rail member 3 is fixed to the upper surface of the plate-like member 5. Then, a recess 15 is formed at a predetermined position on the upper surface of the floor 9 inside the room.

[0044] Next, the plate-like member 5 is placed in the recess 15, and the plate-like member 5 is fixed to the upper surface of the floor 9 in the area where the recess 15 is formed. Then, concrete 17 is poured around the rail member 3 inside the recess 15. The concrete 17 is poured so that the upper surface of the concrete 17, the upper surface of the rail member 3, and the upper surface of the floor 9 in areas other than the recess 15 are approximately flush with each other. In other words, the plate-like member 5 and the rail member 3 are embedded in the concrete 17, and only the upper surface of the rail member 3 (locking claws 4a) is exposed on the upper surface of the concrete 17.

[0045] A sealing member 19 is placed on the end face of the rail member 3 at an appropriate time before pouring the concrete 17. The sealing member 19 prevents the concrete 17 from flowing into the interior of the rail member 3 (between the pair of locking claws 4a). This completes the construction of the equipment fixing floor structure 1a. When pouring the concrete, the opening above the rail member 3 may also be blocked with another sealing member, which may then be removed after pouring the concrete.

[0046] After the equipment fixing floor structure 1a is constructed, the equipment is carried in and fixed onto the rail members 3. The equipment can be fixed to the rail members 3 with bolts or the like. This completes the installation of the equipment.

[0047] As described above, according to the second embodiment, the rail member 3 is installed in the recess 15 formed in the floor 9, and the upper surface of the rail member 3 and the upper surface of the floor 9 in areas other than the recess 15 are made approximately flush with each other, so that the equipment can be installed at approximately the same height as the floor 9.

[0048] In the second embodiment, concrete 17 is poured around the rail member 3, and the upper surface of the concrete 17, the upper surface of the rail member 3, and the upper surface of the floor 9 in areas other than the recessed portion 15 are all substantially flush with each other, so no unevenness is formed on the upper surface of the floor 9 in the area where the equipment is to be installed. This results in a good appearance, and there is no risk of dust accumulating in the recessed portion or tripping over the edges of the rail member 3 or recessed portion 15 during the installation work of the equipment.

[0049] Furthermore, since the seal member 19 is disposed on the end face of the rail member 3, the concrete 17 will not flow into the inside of the rail member 3 and harden, thereby preventing the fixing of the equipment.

[0050] In the second embodiment, as in the first embodiment, when installing equipment, the equipment is fixed to the rail member 3 with bolts or the like, eliminating the need to drive anchors each time the equipment is installed. This makes installation easy and does not generate dust during installation. Furthermore, when replacing equipment, the installation range of the rail member 3 can be adapted to equipment of different sizes.

[0051] In the first and second embodiments, the rail member 3 is fixed to the upper surface of the floor 9 via the plate-like member 5, but the plate-like member 5 is not essential. The rail members 3, 3a may be fixed directly to the upper surface of the floor 9 without the plate-like member 5.

[0052] 6(a) to 6(c) are diagrams showing an example in which the plate-like member 5 is not used. In the example shown in Fig. 6(a), the rail member 3a is fixed to the upper surface of the floor 9 by bolts 11a installed in the portions of the bottom 4b that protrude on both sides of the locking claws 4a.

[0053] In the example shown in Figure 6(b), the rail member 3a is fixed to the upper surface of the floor 9 by adhesive 21. It is desirable that the adhesive 21 be filled entirely between the upper surface of the floor 9 and the lower surface of the bottom portion 4b of the rail member 3a.

[0054] As shown in FIGS. 6(a) and 6(b), if the rail member 3a is fixed directly to the upper surface of the floor 9, the equipment can be installed at a height of the rail member 3 relative to the floor 9, or at a height of the rail member 3 plus the thickness of the adhesive 21. This allows the equipment to be installed at a lower location compared to the case where a plate-like member 5 is used as in the first embodiment. In this case, the bottom 4b extends on both sides of the locking claws 4a, which increases the adhesive area and allows for bolt fixation. Therefore, it is preferable to use the rail member 3a rather than the rail member 3.

[0055] In the example shown in Figure 6(c), rail member 3a is fixed to the bottom surface of recess 15, i.e., the upper surface of floor 9 in the area where recess 15 is formed, with adhesive 21. The upper surface of floor 9 in the area where recess 15 is formed is lower than the upper surface of floor 9 in areas other than recess 15 by the height of rail member 3a plus the thickness of adhesive 21. This makes it possible to make the upper surface of rail member 3a, the upper surface of concrete 17 poured around rail member 3a, and the upper surface of floor 9 in areas other than recess 15 approximately flush with each other.

[0056] 6(c), recesses 15 are formed on the upper surface of floor 9 so as to include an area in which rail members 3a are to be installed. Recesses 15 may be formed so that multiple rows of rail members 3a are installed in one recess 15, or so that one row of rail members 3a is installed in one recess 15.

[0057] Although the embodiments of the present invention have been described above with reference to the accompanying drawings, the technical scope of the present invention is not limited to the above-described embodiments. It is clear that those skilled in the art can conceive of various modifications and alterations within the scope of the technical ideas described in the claims, and it is understood that these modifications and alterations also fall within the technical scope of the present invention.

[0058] For example, it goes without saying that the above-mentioned configurations can be combined with each other. Furthermore, when constructing the equipment fixing floor structure 1, 1a, the rail member 3 may be fixed to the upper surface of the plate-like member 5 after the plate-like member 5 is fixed to the upper surface of the floor 9.
