Description

Heavy type elevated floor

Technical Field

The present invention relates to a floor, and more particularly, to a heavy type raised floor having a rib structure.

Background

At present, the semiconductor factory is equipped with a raised floor with a plurality of micro-perforations to clean the air quality of the environment and ensure the specification of the clean room.

At present, the elevated floor is manufactured by adopting a die casting mode. In the molding process, a desired product is usually manufactured by a mold, and before the molding operation, a releasing layer is coated in the mold to facilitate the subsequent demolding operation.

However, the structural strength of the conventional raised floor is often insufficient, so that the raised floor is easily broken when heavy equipment in a semiconductor process is carried on the raised floor. On the other hand, there is a problem that the raised floor is too heavy, which not only wastes materials but also increases the manufacturing cost.

Therefore, how to overcome the above problems in the prior art has become a problem to be overcome in the industry.

SUMMERY OF THE UTILITY MODEL

In view of the above-mentioned defects of the prior art, the present invention is directed to a heavy raised floor, which can avoid the problem of cracking.

The utility model discloses a heavy elevated floor, include: an antenna panel having opposite ground and honeycomb sides; and a rib structure provided on the honeycomb side of the antenna panel to form a plurality of recesses, wherein the rib structure is defined by a first rib, a second rib, a third rib, a fourth rib, a fifth rib, a sixth rib, and a seventh rib in sequence from the edge to the middle of the antenna panel, and the first to seventh ribs are used as main ribs, and the height of the main ribs relative to the honeycomb side is at least 25 mm.

In the above-mentioned heavy raised floor, the plurality of concave portions are arranged in an array to form a honeycomb structure on the honeycomb side.

In the above-mentioned heavy raised floor, the first rib is formed at the edge of the ceiling to become a side rib of the heavy raised floor, so as to serve as a frame of the heavy raised floor for fixedly connecting the foot seat.

In the aforementioned heavy elevated floor, the sum of the heights of the first rib and the top plate is 51 mm to 62 mm, and the thickness of the top plate is 2.7 mm to 4.8 mm.

In the aforementioned heavy elevated floor, the width of the first rib is 8.3 to 9.8 mm.

In the aforementioned heavy raised floor, the height of the second to seventh ribs with respect to the honeycomb side is 25 to 56.5 mm.

In the aforementioned heavy type raised floor, the widths of the second to seventh ribs are 3.0 to 9.4 mm.

In the aforementioned heavy elevated floor, the rib structure further includes a plurality of auxiliary ribs with a height less than 25 mm, and the plurality of auxiliary ribs are correspondingly formed in each of the recesses, so that the plurality of auxiliary ribs are disposed in a single recess. For example, the plurality of auxiliary ribs extend in a single direction without being staggered with each other. Alternatively, the height of the auxiliary ribs relative to the honeycomb side is at least 6 mm and the width thereof is at least 2.5 mm.

In an embodiment, the top plate has a plurality of through holes formed thereon to communicate the ground side and the honeycomb side, and the through holes are located corresponding to the plurality of concave portions, and the auxiliary rib is disposed between three adjacent through holes.

In the above-mentioned heavy elevated floor, the rib structure forms a # -shaped rib with two seventh ribs in the longitudinal direction and the transverse direction, so as to divide the heavy elevated floor into four regions, 25 sub-regions are formed between the adjacent second, third, fourth, fifth and sixth ribs in the four regions, each sub-region has a concave portion, the first to sixth ribs are symmetrically distributed with the # -shaped rib as a reference, and another rib concave portion is formed at the central part of the # -shaped rib formed by the seventh rib, the thickness of the concave portion is larger than that of the raised floor, a cross shape is arranged in the concave portion, and a wing plate is formed around the raised floor, so that the height of the cross-shaped rib and the thickness of the wing plate are both larger than that of the raised floor, so as to improve the strength of the heavy elevated floor at the middle. For example, 21 other sub-regions are formed in the # -shaped rib by the second, third, fourth, fifth and sixth ribs, and each of the sub-regions has nine through holes, but the through holes are not formed in the sub-region at the central portion of the # -shaped rib.

Therefore, in the heavy raised floor of the present invention, the height of the main rib of the rib structure relative to the honeycomb side is at least 25 mm, so as to improve the structural strength of the heavy raised floor (e.g. at least being able to bear 1500 kg of machine equipment), so as to be able to bear heavier machine equipment in the semiconductor process, thereby avoiding the occurrence of cracking problem in the use of the heavy raised floor.

Fig. 1A, 1B, 1C and 1D are schematic views of a heavy type raised floor 1 according to a first embodiment of the present invention. The heavy elevated floor 1 of the present embodiment is used to carry a heavy load, which carries about 1500 kg.

The heavy type elevated floor 1 has a ceiling 10 and a rib structure 1a provided on the ceiling 10.

The antenna panel 10 has a ground side 10a and a honeycomb side 10b opposite to each other, and the honeycomb side 10b is provided with the rib structures 1a in the longitudinal and transverse directions, respectively, to form a plurality of recesses S between the longitudinal and transverse rib structures 1a, wherein fig. 1C shows only the longitudinal rib structures 1a, and the transverse rib structures 1a are the same as the longitudinal rib structures 1a, so that the cross-section of the transverse rib structures 1a is omitted.

In the present embodiment, the top plate 10 is substantially rectangular, such as a square plate, the length L of the top plate is 600 mm and the thickness t0 of the top plate is 3 mm, a wing plate 1d (the thickness t1 of the wing plate is 6 mm and is greater than the thickness t0 of the top plate 10) is formed around the top plate 10, and foot seats 1b are formed at four corners of the top plate 10, and the bottom of the top plate is in a mouth-shaped convex shape (or a mouth-shaped concave shape) for fixing a support stand (not shown). For example, the foot seats 1b are used to adjust the total height H of the heavy elevated floor 1 so that a plurality of heavy elevated floors 1 are located at the same level.

Furthermore, the ground side 10a is a flat surface and the plurality of recesses S are arranged in an array to form a honeycomb structure having a plurality of pin locations 1c (approximately at the corners of a square area formed by every four recesses S) on the honeycomb side 10 b.

In the rib structure 1a, a first rib 11, a second rib 12, a third rib 13, a fourth rib 14, a fifth rib 15, a sixth rib 16, and a seventh rib 17 are sequentially defined from the edge of the top plate 10 to the middle (or in the left-right lateral direction as shown in fig. 1B and fig. 1C), and heights h1 to h7 of the first to seventh ribs 11 to 17 relative to the honeycomb side 10B are all at least 25 millimeters (mm), so that the first to seventh ribs 11 to 17 serve as main ribs, wherein the first to sixth ribs 11 to 16 are distributed in a left-right symmetrical manner (or in an up-down symmetrical manner as shown in fig. 1B) based on the seventh rib 17 (i.e., a cross-shaped rib) so that a spacing distance w between the second rib 12, the third rib 13, the fourth rib 14, the fifth rib 15, the sixth rib 16, and the seventh rib 17 is 48 mm.

In the embodiment, the first rib 11 is formed at the edge of the top plate 10 to become a side rib of the heavy raised floor 1, so as to serve as a frame of the heavy raised floor 1 for fixedly connecting the foot seat 1b. For example, the height H1 of the first rib 11 relative to the honeycomb side 10b is 50 mm (equal to the heights H2, H7 of the second and seventh ribs 12,17 relative to the honeycomb side 10 b) which is greater than the heights H3-H7 of the third to sixth ribs 13-16 relative to the honeycomb side 10b, the height sum T of the first rib 11 and the ceiling 10 (i.e., the height of the first rib 11 relative to the ground side 10 a) is 53 mm (i.e., T = H1+ T0), and the total height H of the pedestal 1b, the first rib 11 and the ceiling 10 (i.e., the height of the heavy-duty raised floor 1) is 55 mm.

Furthermore, the heights h2 to h7 of the second to seventh ribs of the rib structure 1a may be the same or different according to requirements, and the arrangement of the main ribs (i.e., the second to seventh ribs 12 to 17) between the first rib 11 and the concave portion S at the middle is arranged symmetrically according to height, as shown in fig. 1C. For example, the height h2 of the second rib 12 relative to the honeycomb side 10b is 50 mm, the height h3 of the third rib 13 relative to the honeycomb side 10b is 25 mm, the height h4 of the fourth rib 14 relative to the honeycomb side 10b is 38 mm, the height h5 of the fifth rib 15 relative to the honeycomb side 10b is 38 mm, the height h6 of the sixth rib 16 relative to the honeycomb side 10b is 25 mm, and the height h7 of the seventh rib 17 relative to the honeycomb side 10b is 50 mm, wherein the two longitudinal and transverse seventh ribs 17 form a rib pattern to divide the heavy raised floor 1 into four regions, 25 sub-regions are formed between the adjacent second rib 12, third rib 13, fourth rib 14, fifth rib 15, and sixth rib 16 for each sub-region, each sub-region has a recess S, and another type recess R is formed at the central portion of the rib pattern. Further, the thickness of the top board 10 in the concave portion R may be greater than the thickness t0 of the top board 20 at other positions (i.e., the thickness of the top board 20 at the concave portion R is thickened to 6 mm) or the same as the thickness t0 of the top board 10 as required, and the concave portion R is configured with the cross-shaped rib 17a, and the height h0 of the cross-shaped rib relative to the honeycomb side 10b is 14 mm (greater than the thickness t0 of the top board 10), so as to improve the compressive strength of the heavy type elevated floor 1 at the middle position.

In addition, the widths d1 to d7 of the ribs may be the same or different as required, as shown in fig. 1C, and the widths d2 to d7 of the ribs between the first rib 11 and the middle recess R are designed in a symmetrical manner. For example, the width d1 of the first rib 11 is 8.5 mm, the width d2 of the second rib 12 is 5 mm, the width d3 of the third rib 13 is 3.5 mm, the width d4 of the fourth rib 14 is 3.2 mm, the width d5 of the fifth rib 15 is 3.2 mm, the width d6 of the sixth rib 16 is 3.5 mm, and the width d7 of the seventh rib 17 is 5 mm.

In addition, a plurality of auxiliary ribs 18 with a volume much smaller than that of the main rib may be additionally arranged on the rib structure 1a as required, as shown in fig. 1C, a height h8 (e.g., at least 8 mm) of the auxiliary ribs relative to the honeycomb side 10b is lower than heights h1 to h7 of the main rib relative to the honeycomb side 20b, and a width d8 of the auxiliary ribs is at least 2.5 mm. For example, a plurality of the auxiliary ribs 18 are formed in each of the recesses S, and extend in a single direction without being staggered with respect to each other, and two parallel auxiliary ribs 18 are arranged in a single recess S as shown in fig. 1C.

As can be seen from the above, the thickness t0 of the top plate 10 of the heavy-duty raised floor 1 is small, which is beneficial to saving materials and reducing weight.

Fig. 2A, 2B and 2C are schematic views of a heavy raised floor 2 according to a second embodiment of the present invention. The heavy raised floor 2 of this embodiment is also used for carrying heavy loads, which carry loads exceeding 3000 kg, and the difference from the first embodiment lies in the change of the local height of the rib structure 2a, so the same will not be described in detail below.

In this embodiment, the thickness T0 of the antenna board 20 is 4.5 mm, the height H1 of the first rib 21 relative to the honeycomb side 20B is at least 48.5 mm, the height sum T of the first rib 21 and the antenna board 20 (i.e., the height of the first rib 21 relative to the ground side 20 a) is at least 53 mm, and the total height H of the base 2B, the first rib 21 and the antenna board 20 is at least 55 mm, wherein the thickness T1 of the wing plate 2d is at least 6 mm, the first rib 21 is formed at the edge of the antenna board 20 to become a side rib of the high-rise floor 2, so as to serve as a frame of the high-rise floor 2, and the first to sixth ribs 21 to 26 are distributed in a left-right symmetrical manner (or in a vertical symmetrical manner as shown in fig. 2B) based on the seventh rib 27.

Moreover, the heights h2 to h7 of the second to seventh ribs 22 to 27 relative to the honeycomb side 20b are all at least 48.5 mm, that is, the heights of the first to seventh ribs 21 to 27 are equal to each other. On the other hand, the thickness of the top board 20 at the concave portion R is increased to at least 7.5 mm (i.e. greater than the thickness t0 of the top board 20 at other positions), and the cross-shaped ribs 27a are disposed in the concave portion R, and the height h0 of the cross-shaped ribs relative to the honeycomb side 20b is at least 15 mm (greater than the thickness t0 of the top board 20), so as to improve the compressive strength of the heavy-duty raised floor 2 at the middle position.

In addition, the widths d 1-d 7 of the ribs may be the same or different as required, as shown in FIG. 2C. For example, the width d1 of the first rib 21 is 9.5 mm, the width d2 of the second rib 22 is 8.5 mm, the widths d3 to d6 of the third to sixth ribs 23 to 26 are all 4 mm, and the width d7 of the seventh rib 27 is 6 mm.

In addition, the height h8 of the auxiliary rib 28 with respect to the honeycomb side 20b is at least 6 mm, and the width d8 thereof is at least 2.5 mm.

As can be seen from the above, the heights h1 to h7 of the rib structures 2a are substantially equal to each other, so as to balance the weight distribution.

Fig. 3A, 3B and 3C are schematic views of a heavy raised floor 3 according to a third embodiment of the present invention. The heavy raised floor 3 of the present embodiment is also used for carrying a heavy load, the load carried by the heavy raised floor exceeds 3000 kg, and the difference from the second embodiment is the change of the local height of the rib structure 3a, so the same parts will not be described again.

In this embodiment, the thickness T0 of the antenna board 30 is 4.5 mm, the height H1 of the first rib 31 relative to the honeycomb side 30B is 55.5 mm, the height sum T of the first rib 31 and the antenna board 30 (i.e., the height of the first rib 31 relative to the ground side 30 a) is 60 mm, and the total height H of the base 3B, the first rib 31 and the antenna board 30 is 62 mm, wherein the thickness T1 of the wing plate 3d is 6 mm, the first rib 31 is formed at the edge of the antenna board 30 to serve as a frame of the high-rise heavy floor 3, and the first to sixth ribs 31 to 36 are distributed in left-right symmetry (or in vertical symmetry as shown in fig. 3B) with the seventh rib 37 as a reference.

In the rib structure 3a, as shown in fig. 3C, the height h2 of the second ribs 32 relative to the honeycomb side 30b is 55.5 mm, and the heights h3 to h7 of the third to seventh ribs 33 to 37 relative to the honeycomb side 30b are all 51 mm. On the other hand, the thickness of the top board 30 at the concave portion R is increased to 7.5 mm (i.e. greater than the thickness t0 of the top board 30 at other positions), and the cross-shaped ribs 37a are disposed in the concave portion R, and the height h0 of the cross-shaped ribs relative to the honeycomb side 30b is 15 mm (greater than the thickness t0 of the top board 30), so as to improve the middle compressive strength of the heavy-duty raised floor 3.

In addition, the widths d 1-d 7 of the ribs can be the same or different according to requirements, as shown in FIG. 3C. For example, the width d1 of the first rib 31 is 9.5 mm, the width d2 of the second rib 32 is 9 mm, the widths d3 to d6 of the third to sixth ribs 33 to 36 are all 3.5 mm, and the width d7 of the seventh rib 37 is 5 mm.

In addition, the height h8 of the auxiliary rib 38 with respect to the honeycomb side 10b is at least 6 mm, and the width d8 thereof is 2.5 mm.

As can be seen from the above, the heights h3 to h7 of the rib structures 3a are substantially equal to each other, so as to balance the weight distribution.

Fig. 4A, 4B, 4C and 4D are schematic views illustrating a fourth embodiment of the heavy type raised floor 4 according to the present invention. The difference between this embodiment and the above embodiments is that a through hole is added, so the same parts will not be described in detail.

As shown in fig. 4A, 4B, 4C and 4D, according to the first embodiment, the heavy-duty raised floor 4 forms a plurality of through holes 40 communicating the ground side 10a and the honeycomb side 10B on the top plate 10, and divides the honeycomb side 10B into four regions by the seventh rib 17 (a rib in a matrix shape), each of which forms 25 sub-regions (the recess S), and the rib in a matrix shape is partitioned into 21 other sub-regions (the recesses R, S) by a plurality of the ribs (the second rib 12, the third rib 13, the fourth rib 14, the fifth rib 15 and the sixth rib 16) so that each sub-region has nine through holes 40, and a unidirectional auxiliary rib 18 is provided between adjacent three through holes 40 in each sub-region to reinforce the strength of the top plate 10 between the through holes 40, and it is easier to fabricate a recess hole during die casting, but the through hole 40 is not formed in the sub-region (the recess R) in the central portion of the rib.

In the present embodiment, the positions of the through holes 40 are configured corresponding to the recesses S. For example, nine through holes 40 are formed in each recess S, and the nine through holes 40 are arranged in an array, such that each row has three through holes 40.

Therefore, the through hole 40 may not be formed in the recess R at the central portion of the seventh rib 17 (the cross rib), and the height h0 of the inner cross rib 17a relative to the honeycomb side 10b is greater than the thickness t0 of the top plate 10, so as to improve the strength of the heavy type raised floor 4.

It should be understood that the heavy type raised floors 2,3 of the second and third embodiments may also have a plurality of through holes 40 formed in the recess S thereof.

To sum up, the height h 1-h 7 of the rib structure 1a,2a,3a of the heavy elevated floor 1,2,3,4 of the present invention relative to the honeycomb side 10b,20b,30b is at least 25 mm, so as to enhance the structural strength of the heavy elevated floor 1,2,3,4, and therefore the heavy elevated floor 1,2,3,4 can bear heavier equipment in the semiconductor process, so as to avoid the problem of the heavy elevated floor 1,2,3,4 cracking in use. Furthermore, the height h 1-h 7 and the width d 1-d 7 of the ribs are adjusted according to the load bearing capacity of the heavy elevated floors 1,2,3,4, thereby saving the materials of the heavy elevated floors 1,2,3,4 and reducing the weight.

Furthermore, the structural strength of the heavy-duty raised floor 1,2,3,4 can be further improved by the design of the auxiliary ribs 18,28, 38.

The above embodiments are provided merely for illustrative purposes and not for limiting the scope of the present invention. Any person skilled in the art can modify the above embodiments without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention should be as set forth in the claims.
