Description

Technical Field

[0001] This utility model relates to a support device, and more particularly to a support device for supporting raised floors. Background Technology

[0002] In current anti-static computer rooms and cleanrooms in various technology industries, raised floor systems have become standard equipment for constructing these controlled spaces. To support the increasing number and size of the equipment in these spaces, existing raised floors are mostly made of aluminum alloy through processes such as mold making, aluminum melting, die casting, shaping, and trimming.

[0003] However, when installing a raised floor system, the limited flatness of the underlying building surface can result in an uneven surface after the system is installed. Furthermore, sufficient space must be provided beneath the raised floor for equipment and utility lines to be laid and pass through; therefore, a support system with adjustment mechanisms is necessary to elevate and support the raised floor. In addition, the increasing size and / or centralization of equipment means that the load per unit area of ​​the raised floor is constantly increasing. To support these increasing loads, the structure of the raised floor and support system must be strengthened, and the support systems must be connected in a matrix using trusses to enhance the overall structural strength; otherwise, they cannot stably support these large and centrally located equipment. On the other hand, these raised floors and support systems must also be easy to assemble and install; otherwise, it will delay equipment installation and / or plant construction.

[0004] like Figure 1 As shown, in order to correctly position and fix the raised floor (not shown), the existing support device 1 for raised floors has multiple protruding structures, such as positioning protrusions 111, on its top bearing plate 11. Even if the individual dimensional tolerances of the bearing plate 11 and / or the raised floor installed on it are within the acceptable range, the cumulative tolerances of multiple adjacent raised floors may still cause one or more raised floors to fail to align correctly with the positioning protrusions 111 below. This hinders the assembly and installation work, or even requires on-site grinding and other finishing processes, which seriously affects the assembly and installation work. In order to connect the truss (not shown) to other adjacent support devices (not shown), a support 12 for erecting the truss is provided below the bearing plate 11. However, the existing support usually only has longitudinal and transverse legs 121 to form a cross-shaped structure, but lacks diagonal legs to set the truss. This makes it impossible for the support device 1 to connect with other adjacent support devices diagonally upward, resulting in an unstable overall structure of the final support device array or raised floor system.

[0005] Therefore, overcoming the problems of the existing technology has become an urgent issue that needs to be addressed. Utility Model Content

[0006] In view of the various defects of the prior art, the present invention provides a support device for supporting raised floors. The support device includes: a base; a column fixedly mounted on the base; a rod located on the axis of the column and having a threaded portion, with one end of the rod inserted into the column and the other end extending out of the column; a support seat fixed to the top of the rod and having a flat plate for multiple raised floors to be supported on its top surface at one corner; and a support frame having four mutually perpendicular main legs, wherein the width of the inner end of each main leg is greater than or equal to the width of its outer end. The width of the side end; and a lifting assembly, disposed at the top of the column, the lifting assembly including an anti-lift nut, at least one limiting screw and a rotating member; wherein, the anti-lift nut includes a support top plate through which the rod passes and which is slidably engaged with the top of the column by its bottom periphery, and a circular tube portion connected to the bottom surface of the support top plate and rotatably accommodated in the column; the at least one limiting screw passes through the wall of the column, and one end of the limiting screw extends into and abuts against the circular tube portion of the anti-lift nut after passing through the wall of the column; the rotating member is rotatably engaged with the threaded portion of the rod.

[0007] In the aforementioned support device, the support base is welded and fixed to the top of the rod.

[0008] In the aforementioned support device, the support frame is welded and fixed to the rod body below the support base.

[0009] In the aforementioned support device, the lifting assembly has two limiting screws, and the two limiting screws are symmetrically arranged on both sides of the column with respect to the axis of the column.

[0010] In the aforementioned support device, each of the limiting screws has a driving part at one end exposed outside the column. By rotating the driving part, the limiting screw is rotated to extend into and press against the outer wall of the lifting nut to fix the lifting nut, thereby stopping and tightening the rod. At least one first fixing nut and one second fixing nut are provided at the insertion point of the limiting screw. The first fixing nut is fixed on the surface of the column, and by rotating the second fixing nut, it presses against the first fixing nut, so that the limiting screw is fixed by the first fixing nut and the second fixing nut together.

[0011] In the aforementioned support device, the limiting screw abuts against a recess on the outer wall of the cylindrical portion of the lifting nut.

[0012] In the aforementioned support device, the recess is a groove formed around the outer wall of the circular tube.

[0013] In the aforementioned support device, the support frame is sleeved under the support base and includes oblique legs that extend obliquely between two adjacent main legs, and the width of the inner end of each oblique leg is greater than or equal to the width of its outer end.

[0014] In the aforementioned support device, a truss beam is respectively mounted on the main support leg and the inclined support leg for connecting the support device to another adjacent support device.

[0015] In the aforementioned support device, the outer sides of each inclined support leg are recessed to form a stop at the connection between the outer and inner ends of each inclined support leg, thereby stopping and positioning the truss beam mounted on the inclined support leg.

[0016] In the aforementioned support device, each of the main support legs and each of the inclined support legs has a locking hole formed on its outer end for locking the truss beam mounted on the main support leg or the inclined support leg.

[0017] In the aforementioned support device, the lifting assembly contains three of these limiting screws.

[0018] As can be seen from the above, the support device of this utility model mainly uses the top surface of the flat plate of the support base to prevent the raised floor from being affected by the cumulative tolerance of multiple adjacent raised floors when it is erected on it, thus greatly simplifying the assembly and erection of the raised floor. In addition, by adding diagonal legs between the main legs of the support frame, each support device can add trusses to connect with other diagonally adjacent support devices, greatly improving the overall structural strength and stability of the support device array composed of multiple support devices.

[0061] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0062] It should be understood that the structures, proportions, sizes, etc., shown in the accompanying drawings are only for illustrative purposes to aid those skilled in the art and to facilitate understanding and reading of the disclosed content. They are not intended to limit the implementation conditions of this utility model and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to the size, without affecting the effects and objectives achieved by this utility model, should still fall within the scope of the disclosed technical content. Furthermore, the terms such as "upper," "lower," "left," "right," "front," "rear," "first," "second," and "a" used in this specification are merely for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of implementation of this utility model.

[0063] Please see Figures 2A to 2C These are schematic diagrams related to an embodiment of the support device of this utility model; Figure 3A , Figure 3B and Figure 3C This is a schematic diagram of an embodiment of a support device array using the support device of this utility model. In this embodiment, the support device 2 defines the direction of the truss beam as the left and right directions (e.g., Figure 2A , Figure 2B and Figure 2C The arrow direction (X) and the forward and backward directions (e.g.) Figure 2A and Figure 2B The arrow direction is Y), while the direction along the height of the support device 2 is defined as the up and down directions (e.g., the arrow direction is Y). Figure 2A , Figure 2B and Figure 2C (The arrow in the diagram points to the direction Z). It should be understood that this orientation is used to illustrate the configuration of this embodiment and is not particularly limiting.

[0064] like Figure 2A , Figure 2B and Figure 2C As shown, the support device 2 provided in this embodiment includes: a base 21, a column 20, a rod 22, a support seat 24, a support frame 23, and a lifting assembly 2a.

[0065] The base 21 is a rectangular plate that is fixed to the ground by means of fasteners (not shown) such as bolts or expansion screws passing through multiple through holes 210. For example, the multiple through holes 210 are arranged at the four corners of the base 21.

[0066] The column 20 is typically a hollow cylindrical metal column, such as steel or alloy, and this embodiment does not have any particular limitations in this regard. Its bottom end is fixed to the center of the base 21, while the rod 22 is inserted into the top of the column 20.

[0067] The rod 22 is located on the axis of the column 20 and is coaxially arranged with the column 20. One end of the rod is inserted into the column 20, and the other end extends from the top of the column 20. The outer peripheral surface of the rod 22 includes a threaded portion 22a. The threaded portion 22a may only cover a partial range along the length of the outer peripheral surface of the rod 22, but in this embodiment, the threaded portion 22a extends to cover the entire outer peripheral surface of the rod 22. That is to say, the rod 22 in this embodiment is a screw.

[0068] Please also refer to Figure 3A In this embodiment, the support base 24 is a metal plate with an approximately square outer contour and a flat plate body for four raised floor panels 4 to be respectively mounted on the top surface of the support base 24 at one corner. The support base 24 and the support frame 23 are separately arranged, which not only increases the load-bearing area of ​​the support base 24, but also allows the support base 24 to use a thicker steel plate, thus enabling it to bear a larger load. However, the support base 24 and the support frame 23 can also be made by stamping to increase the thickness of the steel plate of the support base 24. Therefore, as... Figure 3A As shown, each support base 24 can simultaneously support up to four raised floor panels 4, each with one corner mounted on the support base 24. Since the top surface of the support base 24 is flat, no special attention is needed for precise alignment when placing the raised floor panels 4 on the support base 24. Alignment and positioning can be completed simply by having any two adjacent raised floor panels 4 abut against each other. This greatly simplifies the work of erecting the raised floor panels 4 and speeds up the entire erection process.

[0069] Preferably, a first fixing hole 241 is formed at each of the four corners of the support base 24, and a fixing hole 40 corresponding to the first fixing hole 241 is formed at each corner of the raised floor 4, so that a fixing screw (not shown) can pass through the fixing hole 40 of each raised floor 4 and be locked in the corresponding first fixing hole 241, thereby fixing the raised floor 4 to the top surface of the support base 24.

[0070] In this embodiment, the support base 24 is provided and fixedly joined to the top of the rod 22 by means of welding, thereby providing better structural strength. However, in other variations, a snap-fit ​​structure (not shown) may be provided or formed at the bottom of the support base 24 and the top of the rod 22 to engage or fasten the support base 24 to the rod 22, or corresponding threads (not shown) may be formed on the support base 24 and the rod 22 to screw the support base 24 to the rod 22. This embodiment does not have any particular limitations in this regard.

[0071] Please also refer to Figure 3B and Figure 3C The support frame 23 is a metal plate fixedly sleeved on the rod 22 below the support base 24, and has four main support legs 231 extending perpendicularly to each other in the arrow directions X and Y, and four oblique support legs 232 extending obliquely between two adjacent main support legs 231, and the width of the inner end of each main support leg 231 and each oblique support leg 232 is greater than or equal to the width of its outer end. And as... Figure 3A , Figure 3B and Figure 3C As shown, a truss beam 3 is respectively mounted on the main support leg 231 or the inclined support leg 232 to connect the support device 2 with another adjacent support device 2, so as to form a support device array 2S of multiple support devices 2, thereby improving the overall structural strength and stability of the support device array 2S.

[0072] Preferably, each main support leg 231 and each diagonal support leg 232 has a locking hole 233 near its outer end, and each truss 3 has a second fixing hole 30 near its end, so that a screw 31 can pass through the second fixing hole 30 and be locked in the locking hole 233, thereby fixing the end of each truss 3 to the corresponding main support leg 231 or diagonal support leg 232.

[0073] Similar to the support base 24, the support frame 23 can also be fixed to the rod 22 below the support base 24 by welding. Alternatively, in other variations, the support frame 23 can be screwed onto the rod 22 below the support base 24 by forming corresponding threads (not shown) together with the rod 22. This embodiment does not impose any limitations on this.

[0074] Furthermore, the outer ends of each inclined support 232 can be recessed on both sides to form a stop 232s at the junction of the outer and inner ends of each inclined support 232, thereby stopping and positioning the truss 3 mounted on the inclined support 232. At the same time, because the outer ends of the inclined support 232 are recessed on both sides, the sides of the truss 3 will not protrude excessively toward the main supports 231 after being mounted on the inclined support 232, thus preventing interference with the truss 3 mounted on the main supports 231.

[0075] The lifting assembly 2a is located at the top of the column 20 and includes an anti-lift nut 25, at least one limiting screw 26, a first fixing nut 261, a second fixing nut 262 and a rotating component 27.

[0076] The lifting nut 25 is used for the rod body 22 to pass through. For example... Figure 2C As shown, the lifting nut 25 includes a supporting top plate 251 and a circular tube portion 252. The supporting top plate 251 is a metal plate, and the rod 22 is movably inserted through the center of the supporting top plate 251. As described above, the rod 22 has a threaded portion 22a, so a threaded hole can be formed in the center of the lifting nut 25 for the rod 22 to pass through and engage with the threaded portion 22a, so that the rod 22 and the lifting nut 25 can be rotatably engaged, and the rod 22 can move up and down by rotating relative to the lifting nut 25.

[0077] The circular tube portion 252 is fixedly attached to the bottom of the support top plate 251, and the circular tube portion 252 is rotatably accommodated within the column 20. The periphery of the support top plate 251 protrudes from the upper outer side of the circular tube portion 252 and the outer wall of the column 20, allowing the support top plate 251 to be slidably supported on the top of the column 20 by its bottom periphery. Preferably, the support top plate 251 can be hexagonal with symmetrical opposite sides, and a tool can be used to apply force to at least two opposite sides of the hexagon to rotate the support top plate 251, thereby causing the lifting nut 25 to rotate as a whole.

[0078] At least one limiting screw 26 passes through the wall of the column 20, and one end of the limiting screw 26 extends into and abuts against the round tube portion 252 of the lifting nut 25 after passing through the wall of the column 20. The rotating member 27 may be a nut, such as the hexagonal nut shown in this embodiment, which is rotatably screwed onto the threaded portion 22a of the rod 22 between the lifting nut 25 and the support frame 23.

[0079] The four corners of the raised floor 4 are respectively fixed to the support device 2, for example... Figure 3A and Figure 3BBefore the support base 24 of the support device 2, multiple support devices 2 are first fixed on the ground, and multiple trusses 3 are respectively erected on the support frames 23 of the multiple support devices 2 to form a mesh structure. Since in this embodiment, in addition to the trusses 3 erected along the horizontal and vertical directions, the multiple support devices 2 also have trusses 3 erected and fixed along the diagonal direction on the diagonal support legs 232 of two adjacent support devices 2 along the diagonal direction, the resulting support device array 2S is more stable and has higher overall structural strength than the existing support device array which only has trusses 3 erected along the horizontal and vertical directions.

[0080] After the raised floor 4 is fixed to the support base 24 of each support device 2, rotating the anti-lift nut 25 will cause the rod 22 to move vertically, that is, the rod 22 will move upward or downward relative to the column 20 and the support device 2 as a whole (i.e., along the line). Figure 2C The arrow in the middle points Z (as it moves up and down) to adjust the level of the raised floor 4. After adjustment, rotate the rotating part 27 to lock it with the anti-lift nut 25, so that the rod 22 is fixed at the correct height by the rotating part 27 and the anti-lift nut 25.

[0081] Please refer to the following: Figure 2C The limiting screw 26 passes through the wall of the column 20, and one end of the limiting screw 26 extends into and abuts against the wall surface of a recess in the lifting nut 25 after passing through the wall of the column 20. In this embodiment, the recess is a channel 253 formed around the outer wall surface of the circular tube portion 252. The limiting screw 26 abuts against the channel 253 to fix the lifting nut 25. Since the rod 22 adjusts its length extending out of the column 20 by rotating relative to the lifting nut 25, fixing the lifting nut 25 and the rotating member 27 also stops and tightens the rod 22.

[0082] In a specific embodiment, the lifting assembly 2a includes at least one limiting screw 26. And as... Figure 2C As shown, this embodiment uses two limiting screws 26 symmetrically arranged on the periphery of the column 20 relative to its axis as an example. However, multiple screws, such as three or four, can be used as needed, and this embodiment does not impose any restrictions on this. Tests showed that the tensile strength of three limiting screws 26 was 3418 kg, the tensile strength of two limiting screws 26 was 2197 kg, and the tensile strength of one limiting screw 26 was 986 kg. It can be seen that the tensile strength of three limiting screws 26 is more than three times that of one limiting screw 26, and the tensile strength of three limiting screws 26 is 1.6 times that of two limiting screws 26. Therefore, using three limiting screws 26 can significantly increase the tensile strength of the tripod.

[0083] The end of the limiting screw 26 exposed outside the column 20 has a driving portion 260. The driving portion 260 can be polygonal, such as a hexagonal block, that is, the limiting screw 26 can be a hexagonal screw. Alternatively, the driving portion 260 can be a block with triangular, square, hexagonal, star-shaped, or star-shaped recesses, that is, the limiting screw 26 can be an internal triangular, internal square, internal hexagonal, or star-shaped or star-shaped screw. By rotating the driving portion 260 with a tool corresponding to its configuration, the limiting screw 26 is rotated and inserted into the column 20 and pressed against the groove 253 of the lifting nut 25. In this embodiment, two internal hexagonal screws are used as examples of the limiting screw 26.

[0084] Additionally, a first fixing nut 261 may be provided at each insertion point of the limiting screw 26 on the column 20, so that the limiting screw 26 passes through the wall of the column 20 after being screwed into the first fixing nut 261. In some embodiments, the first fixing nut 261 may be fixed to the surface of the column 20 by welding or other means. In other variations, a second fixing nut 262 is further connected between the driving part 260 of each limiting screw 26 and the first fixing nut 261, and the limiting screw 26 is fixed by the first fixing nut 261 and the second fixing nut 262 by rotating the second fixing nut 262 to press against the first fixing nut 261.

[0085] Thus, the support device 2 provided in this embodiment is used to erect... Figure 3A In the elevated floor system, firstly, multiple support devices 2 are installed on the ground. Then, multiple trusses 3 are respectively erected on the support frames 23 of the multiple support devices 2 to form a support device array 2S with a mesh support structure. Then, the extension length of the rods 22 is adjusted by the lifting assembly 2a to adjust the height of each support seat 24. Afterwards, multiple rectangular elevated floor panels 4 can be arranged on the multiple support devices 2 in the support device array 2S, and... Figure 3A Screws (not shown) are inserted into the fixing holes 40 at each corner of each raised floor 4 to fix the four corners of each raised floor 4 to a support device 2, thereby forming a structure. Figure 3A The raised floor system shown.

[0086] In summary, the support device of this utility model, through the top surface of its flat plate, prevents the raised floor from being affected by the cumulative tolerances of multiple adjacent raised floors when it is erected on it, thus greatly simplifying the assembly and erection of the raised floor. Furthermore, by adding diagonal supports between the main legs of the support frame, each support device can have additional trusses connecting to other diagonally adjacent support devices, significantly improving the overall structural strength and stability of the support device array composed of multiple support devices.

[0087] The above embodiments are illustrative of the principles and effects of this utility model, and are not intended to limit this utility model. Those skilled in the art can modify the above embodiments without departing from the spirit and scope of this utility model. Therefore, the scope of protection of this utility model should be as set forth in the claims.
