Description

Heavy type elevated floor

Technical Field

The present invention relates to a floor structure, and more particularly, to a heavy 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 release 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 difficult problem to be overcome in the present 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 of the antenna panel to the middle, and the first to fifth and seventh ribs have a height of at least 25 mm with respect to the honeycomb side to serve as main ribs, and the sixth rib has a height of less than 25 mm with respect to the honeycomb side to serve as middle ribs.

In the above-mentioned heavy-duty 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 raised floor, the height of the first rib relative to the honeycomb side is greater than the height of the second to seventh ribs relative to the honeycomb side, and the sum of the heights of the first rib and the top plate is at least 57.5 mm, and the thickness of the top plate is at least 2.5 mm.

In the aforementioned heavy elevated floor, the width of the first rib is at least 8.5 mm.

In the aforementioned heavy raised floor, the heights of the second to fifth ribs and the seventh rib with respect to the honeycomb side are 25 to 53 mm.

In the aforementioned heavy elevated floor, the widths of the second to fifth ribs and the seventh rib are 2.3 mm to 5.0 mm.

In the aforementioned heavy elevated floor, the height of the sixth rib relative to the honeycomb side is at least 20 mm.

In the aforementioned heavy elevated floor, the width of the sixth rib is at least 2.5 mm.

In the aforementioned heavy raised floor, the rib structure further includes a plurality of auxiliary ribs having a height lower than the middle rib, 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 secondary ribs relative to the honeycomb side is at least 4 mm and the width thereof is at least 2.5 mm.

In the aforementioned heavy raised floor, the top plate is formed with a plurality of through holes communicating the ground side and the honeycomb side, and the through holes are located corresponding to the plurality of recesses, and the auxiliary rib is disposed between three adjacent through holes.

In the aforementioned heavy elevated floor, the rib structure forms a # -shaped rib with two seventh ribs in the longitudinal direction and the transverse direction 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 recess, and another recess is formed in the center of the # -shaped rib formed by the seventh rib, a cross rib is disposed in the recess, the thickness of the recess is increased more than that of the ceiling, and a wing plate is formed around the ceiling, so that the height of the cross rib and the thickness of the wing plate are both increased more than that of the ceiling, thereby increasing the strength of the heavy elevated floor in the middle. For example, the first to sixth ribs are symmetrically distributed with respect to the # -shaped rib, and the # -shaped rib forms an inclined plane at a position where the first rib is connected, so as to reduce the weight of the heavy-duty raised floor. Or, 21 other sub-regions are formed in the # -shaped rib by the second rib, the third rib, the fourth rib, the fifth rib and the sixth rib at intervals, and each sub-region is provided with nine through holes, but the through holes are not formed in the sub-region at the central part 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 illustrating a first embodiment of a heavy type raised floor 1 according to 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, the thickness t0 of the top plate is at least 2.5 mm, a wing plate 1d (the thickness t1 of the wing plate is 6 mm, which 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 L-shaped convex (or L-shaped concave) for fixing a support foot 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.

The rib structure 1a is formed by sequentially defining 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 from the edge of the top plate 10 to the middle (or in the left-right direction as shown in fig. 1B and 1C), wherein the heights h1 to h5 and h7 of the first to fifth and seventh ribs 11 to 15,17 relative to the honeycomb side 10B are at least 25 millimeters (mm), and the height h6 of the sixth rib 16 relative to the honeycomb side 10B is less than 25 mm, so that the first to fifth and seventh ribs 11 to 15,17 are used as main ribs, and the sixth rib 16 is used as a middle rib, wherein the first to sixth ribs 11 to 16 are distributed symmetrically left and right (or symmetrically up and down as shown in fig. 1B) based on the seventh rib 17 (mm), so that the distance between the second, third, fourth, fifth and sixth ribs 12, 15 and 16 is w.

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 at least 55 mm, which is greater than the heights H2 to H7 of the second to seventh ribs 12 to 17 relative to the honeycomb side 10b, the heights T of the first rib 11 and the antenna board 10 (i.e., the height of the first rib 11 relative to the ground side 10 a) are 57.5 mm (i.e., T = H1+ T0), and the total height H of the base 1b, the first rib 11 and the antenna board 10 (i.e., the height of the heavy elevated floor 1) is at least 60 mm.

Furthermore, the heights h2 to h7 of the second to seventh ribs 12 to 17 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 fifth ribs 12 to 15 and the seventh rib 17, excluding the sixth rib 16) between the first rib 11 and the concave portion S at the middle is arranged symmetrically according to the 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 35 mm, the height h5 of the fifth rib 15 relative to the honeycomb side 10b is 25 mm, the height h7 of the seventh rib 17 relative to the honeycomb side 10b is 50 mm, and the height h6 of the sixth rib 16 relative to the honeycomb side 10b is 20 mm, wherein the two longitudinal and transverse seventh ribs 17 form a well-shaped rib, so that the high shelf floor 1 is divided 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 in each region, each sub-region has a recess S, and another type of recess R is formed at the central portion of the seventh rib 17. Further, the thickness of the top board 10 at the concave portion R is increased by at least 5.5 mm (i.e. greater than the thickness t0 of the top board 10 at other positions), and the cross-shaped ribs 17a are disposed in the concave portion R, and the height h0 of the cross-shaped ribs relative to the honeycomb side 10b is 10 mm (greater than the thickness t0 of the top board 20), so as to improve the compressive strength of the heavy-duty raised floor 1 at the middle.

In addition, the widths d 1-d 7 of the ribs may be the same or different as required, as shown in FIG. 1C. For example, the width d1 of the first rib 11 is 8.5 mm, the width d2 of the second rib 12 is 4 mm, the width d3 of the third rib 13 is 2.5 mm, the width d4 of the fourth rib 14 is 3 mm, the width d5 of the fifth rib 15 is 2.5 mm, the width d6 of the sixth rib 16 is 2.5 mm, and the width d7 of the seventh rib 17 is 4.8 mm.

In addition, a plurality of auxiliary ribs 18 having a volume much smaller than that of the other ribs may be additionally provided to the rib structure 1a as required, wherein a height h8 (e.g., at least 4 mm) of the auxiliary ribs relative to the honeycomb side 10b is lower than a height h6 of the middle rib relative to the honeycomb side 10b, 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. 1B.

As can be seen from the above, the thickness t0 of the top board 10 of the heavy elevated floor 1 is smaller, and the height h6 of the rib structure 1a is also smaller, i.e. the height h6 of the middle rib (the sixth rib 16) is much smaller than the heights h 1-h 5, h7 of the main ribs (the first to fifth and seventh ribs 11-15, 17), so as to save material and reduce weight.

Furthermore, the cross-shaped rib formed by the seventh rib 17 forms an inclined plane at the position where the first rib 11 is connected, so as to reduce the weight of the heavy elevated floor 1.

Fig. 2A, 2B, 2C and 2D are schematic views of a heavy raised floor 2 according to a second embodiment of the present invention. The difference between this embodiment and the above embodiments is that a new perforation is added, so the same parts will not be described in detail below.

As shown in fig. 2A, 2B, 2C and 2D, the heavy-duty raised floor 2 is formed with a plurality of through holes 20 communicating the ground side 10a and the honeycomb side 10B on the top plate 10, and the honeycomb side 10B is divided into four regions by the seventh rib 17 (cross rib), each of which is further formed with 25 sub-regions (the recess S), the cross rib is formed with 21 other sub-regions (the recesses R, S) spaced by 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 20, and a unidirectional auxiliary rib 18 is provided between adjacent three through holes 20 in each sub-region to reinforce the strength of the top plate 10 between the through holes 20, and it is easier to make a concave hole in the die casting process, but the through hole 20 is not formed in the sub-region (the recess R) at the central portion of the cross rib.

In the present embodiment, the positions of the through holes 20 are arranged corresponding to the recesses S. For example, nine through holes 20 are formed in each recess S, and the nine through holes 20 are arranged in an array, such that each row has three through holes 20.

Therefore, the through hole 20 may not be provided in the recess R at the central portion of the seventh rib 17 (i.e., the # -shaped rib), and the height h0 (e.g., 10 mm) of the inner cross-shaped 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-duty raised floor 2.

To sum up, the height h 1-h 5, h7 of the main rib of the rib structure 1a relative to the honeycomb side 10b is at least 25 mm for the heavy type raised floor 1,2 of the present invention, so as to enhance the structural strength of the heavy type raised floor 1,2, and the heavy type raised floor 1,2 can bear the heavy machine equipment in the semiconductor process, so as to avoid the problem that the heavy type raised floor 1,2 is cracked 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 floor 1,2, that is, the height h 1-h 7 and the width d 1-d 7 of the ribs are smaller when the load bearing capacity is small, so as to save the material of the heavy elevated floor 1,2 and reduce the weight.

Furthermore, the structural strength of the heavy raised floors 1,2 can be further improved by the design of the auxiliary ribs 18.

The above embodiments are merely illustrative of the principles and effects of the present invention, and are not to be construed as limiting the invention. Those 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.
