Description

Standard elevated floor

Technical Field

The invention relates to a floor structure, in particular to a standard raised floor with a rib structure.

Background

In the existing semiconductor factory building, a raised floor with a plurality of micro-holes is configured to clean the air quality of the environment and ensure the specification of the clean room.

At present, raised floors are manufactured in a die casting mode. In the die casting process, a die is used to manufacture a desired product, and before the die casting operation is performed, a release layer is coated in the die to facilitate the subsequent demolding operation.

However, the structural strength of the existing raised floor is often insufficient, so that when the raised floor is used for carrying heavy equipment in the semiconductor process, the raised floor is easy to crack. On the other hand, there is also a problem that the raised floor is excessively heavy, not only wastes materials, but also increases manufacturing costs.

Therefore, how to overcome the above-mentioned problems in the prior art has become a major challenge in the industry.

Disclosure of Invention

In view of the above-mentioned drawbacks of the prior art, an object of the present invention is to provide a standard raised floor, which can avoid the problem of chipping.

The invention provides a standard elevated floor, comprising: a ceiling having opposite ground and honeycomb sides; and a rib structure disposed on the honeycomb side of the antenna plate to form a plurality of recesses, wherein the rib structure is defined with 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 plate to the middle, the heights of the first rib, the third rib and the seventh rib relative to the honeycomb side are at least 25 mm to serve as main ribs, and the heights of the second rib, the fourth rib, the fifth rib and the sixth rib relative to the honeycomb side are lower than 25 mm to serve as middle ribs.

In the standard raised floor, the plurality of recesses are arranged in an array to form a honeycomb structure on the honeycomb side.

In the standard raised floor, the first rib is formed at the edge of the ceiling to form a side rib of the standard raised floor, so as to serve as a frame of the standard raised floor for fixedly connecting the foot stand.

In the standard raised floor, the height of the first rib relative to the honeycomb side is greater than the height of the second rib to the seventh rib relative to the honeycomb side, the sum of the heights of the first rib and the ceiling plate is 47 mm, and the thickness of the ceiling plate is 3 mm.

In the standard raised floor, the width of the first rib is 7 mm.

In the standard raised floor, the third and seventh ribs have a height of 34.5 mm relative to the honeycomb side.

In the standard raised floor, the third and seventh ribs have a width of 3 to 4 mm.

In the standard raised floor, the heights of the second rib, the fourth rib, the fifth rib and the sixth rib are 6 to 19 mm relative to the honeycomb side.

In the standard raised floor, the widths of the second rib, the fourth rib, the fifth rib and the sixth rib are 3.2 mm.

In the standard raised floor, the rib structure further comprises a plurality of auxiliary ribs having a height lower than that of the middle rib, and the plurality of auxiliary ribs are correspondingly formed in each of the recesses, so that a plurality of the auxiliary ribs are disposed in a single recess. For example, the plurality of auxiliary ribs extend in multiple directions to be staggered with each other. Alternatively, the auxiliary rib has a height of 2 mm and a width of 3 mm with respect to the honeycomb side.

In the standard raised floor, a plurality of through holes are formed in the ceiling plate to communicate the floor side and the honeycomb side, and the positions of the through holes correspond to the plurality of concave parts.

In the standard raised floor, the rib structure forms a cross rib with two seventh ribs in the longitudinal direction and the transverse direction so as to divide the standard raised floor into four areas, 25 subregions are formed among the adjacent second ribs, third ribs, fourth ribs, fifth ribs and sixth ribs in the four areas, each subregion is provided with a concave part, another concave part is formed at the central part of the cross rib formed by the seventh ribs, a cross rib is configured in the concave part, and a wing plate is formed around the ceiling plate, so that the height of the cross rib and the thickness of the wing plate are both larger than the thickness of the ceiling plate, and the strength of the standard raised floor at the middle position is improved. For example, the first rib to the sixth rib are symmetrically distributed with the groined rib as a reference, and the groined rib forms an inclined plane at the position connecting the first rib, so as to reduce the weight of the standard raised floor. Or 21 other subregions are separated from each other by the second rib, the third rib, the fourth rib, the fifth rib and the sixth rib in the cross rib, and nine through holes are formed in each subregion, but the through holes are not formed in the subregion of the central part of the cross rib.

As can be seen from the above, in the standard raised floor of the present invention, the main rib of the rib structure has a height of at least 25 mm relative to the honeycomb side, so as to improve the structural strength of the standard raised floor (e.g. at least the machine equipment with a weight of 700 kg), so that the standard raised floor can bear the heavier machine equipment in the semiconductor process, compared with the prior art, so as to avoid the problem of cracking of the standard raised floor in use.

It should be understood that the structures, proportions, sizes, etc. shown in the drawings attached hereto are for the purpose of understanding and reading only and are not intended to limit the scope of the invention, which is defined by the appended claims, but rather by the appended claims. Also, the terms such as "upper", "lower", "left", "right" and "a" and the like are used in the present specification for convenience of description, but are not intended to limit the scope of the present invention, and the relative changes or modifications thereof are considered to be within the scope of the present invention without substantial modification of the technical content.

Fig. 1A, 1B, 1C, 1D and 1E are schematic views of a first embodiment of a standard raised floor 1 according to the present invention. The standard raised floor 1 of the present embodiment is used to carry a light load, which carries a load of about 700 kg.

The standard raised floor 1 has a ceiling 10 and a rib structure 1a provided on the ceiling 10.

The antenna board 10 has opposite ground sides 10a and honeycomb sides 10b, and the honeycomb sides 10b are respectively provided with the rib structures 1a in the longitudinal direction and the transverse direction to form a plurality of recesses S between the longitudinal and the transverse rib structures 1a, wherein fig. 1C shows the transverse rib structures 1a, and fig. 1D shows the longitudinal rib structures 1a.

In the present embodiment, the top board 10 is a rectangular body, such as a square board, with a length L of 600 mm and a thickness t0 of 3.0 mm, and a wing board 1d (with a thickness t1 of 6.25 mm, greater than the thickness t0 of the top board 10) is formed around the top board 10, and the four corners of the top board 10 are formed with feet 1b, the bottoms of which are shaped like a mouth (or concave) for fixing a supporting foot stand (not shown). For example, the footstand 1b is used to adjust the overall height H of the standard raised floor 1 such that a plurality of standard raised floors 1 are located at the same horizontal plane.

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

The rib structure 1a is defined with 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 sequentially from the edge of the ceiling 10 to the middle (or from the top to bottom to the middle as shown in fig. 1B), the first, third and seventh ribs 11,13,17 are at least 25 mm (mm) relative to the height h1, h3, h7 of the honeycomb side 10B, and the second, fourth to sixth ribs 12,14,15,16 are below 25 mm relative to the height h2, h4, h5, h6 of the honeycomb side 10B, so that the first, third and seventh ribs 11,13,17 are used as main ribs, and the second, fourth to sixth ribs 12,14,15,16 are used as middle ribs, wherein the first to sixth ribs 11 to 16 are laterally symmetrical (or from top to bottom as shown in fig. 1B) relative to the seventh ribs 17 (or from the cross ribs) and the seventh ribs 17 are symmetrically distributed, and the distances between the second, third and fourth ribs 11,13,17 are equal to the fifth ribs 12,14,15,16 and the seventh ribs 48 are respectively.

In this embodiment, the first rib 11 is formed at the edge of the ceiling board 10 to form a side rib of the standard raised floor 1, so as to serve as a frame of the standard raised floor 1 for fixedly connecting the foot stand 1b. For example, the height H1 of the first rib 11 relative to the honeycomb side 10b is 44 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 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 47 mm (i.e., t=h1+t0), and the total height H of the footstand 1b, the first rib 11 and the ceiling 10 (i.e., the foot height of the standard raised floor 1) is 55 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 as required, as shown in fig. 1C. For example, the height h3 of the third rib 13 relative to the honeycomb side 10b is 34.5 mm, the height h7 of the seventh rib 17 relative to the honeycomb side 10b is 34.5 mm, the height h2 of the second rib 12 relative to the honeycomb side 10b is 19 mm, the height h4 of the fourth rib 14 relative to the honeycomb side 10b is 6 mm, the height h5 of the fifth rib 15 relative to the honeycomb side 10b is 19 mm, and the height h6 of the sixth rib 16 relative to the honeycomb side 10b is 6 mm, wherein the two seventh ribs 17 in the longitudinal and transverse directions form a groined rib to divide the standard raised floor 1 into four areas, 25 sub-areas are formed among the second rib 12, the third rib 13, the fourth rib 14, the fifth rib 15 and the sixth rib 16 adjacent to each other, each sub-area has a recess S, and another recess R is formed at the center of the well of the seventh rib 17. Further, the thickness of the top board 10 at the recess R is the same as the thickness t0 at other places (or the recess R may be thickened, for example, about 1-3 mm greater than the thickness t0 of the top board 10 at other places), and the cross-shaped ribs 17a are disposed in the recess R, which have a height h0 of 8 mm (greater than the thickness t0 of the top board 10) relative to the honeycomb side 10b, so as to improve the compressive strength of the standard raised floor 1 at the middle.

In addition, the widths d 1-d 7 of the ribs may be the same or different as desired, as shown in FIG. 1C. For example, the width d1 of the first rib 11 is 7 mm, the width d2 of the second rib 12 is 3.2 mm, the width d3 of the third rib 13 is 3 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 3.2 mm, and the width d7 of the seventh rib 17 is 4 mm.

In addition, the rib structure 1a may be additionally provided with a plurality of auxiliary ribs 18 with a volume far smaller than that of other ribs according to requirements, the height h8 (e.g. 2 mm) of the auxiliary ribs relative to the honeycomb side 10b is lower than the heights h2, h4, h5, h6 of the middle ribs relative to the honeycomb side 10b, and the width d8 is 3 mm. For example, the plurality of auxiliary ribs 18 are formed in the plurality of recesses S so as to extend in both directions and to intersect each other, and two intersecting auxiliary ribs 18 are arranged in a single recess S as shown in fig. 1B.

Further, the heights h4 to h6 of the fourth to sixth ribs 14 to 16 of the standard raised floor 1 are sequentially low/high/low, so that the heights h4 to h6 of the fourth to sixth ribs 14a to 16a can be adjusted by designing the rib structure 1a in the other direction (the left-right direction as shown in fig. 1B) as shown in fig. 1D, except that the fourth to sixth ribs 14a to 16a are different, and the other ribs are all the same size. For example, the height h4 of the fourth rib 14a relative to the honeycomb side 10b is 19 mm, the height h5 of the fifth rib 15a relative to the honeycomb side 10b is 34.5 mm, and the height h6 of the sixth rib 16a relative to the honeycomb side 10b is 19 mm, so that the heights h4 to h6 of the fourth to sixth ribs 14a to 16a are still arranged in order of low/high/low, but the fifth rib 15a becomes the main rib, and the width d5 of the fifth rib is 3 mm.

As can be seen from the above, the thickness t0 of the ceiling 10 of the standard raised floor 1 is smaller, and the heights h2, h4, h5, h6 of the majority of the rib structures 1a are also smaller, i.e. the heights h2, h4, h5, h6 of the middle ribs (the second, fourth, fifth and sixth ribs 12,14,15, 16) are much smaller than the heights h1, h3, h7 of the main ribs (the first rib 11, the third rib 13 and the seventh rib 17), so as to facilitate saving materials and reducing weight.

Furthermore, the cross rib formed by the seventh rib 17 is inclined at the position where the first rib 11 is connected to reduce the weight of the standard raised floor 1.

Fig. 2A, 2B, 2C and 2D are schematic views of a second embodiment of a standard raised floor 2 according to the present invention. The difference between the present embodiment and the above embodiment is that the perforation is newly added, so the same parts will not be repeated hereinafter.

As shown in fig. 2A, 2B, 2C and 2D, the standard raised floor 2 forms a plurality of through holes 20 on the ceiling 10, which are connected to the ground side 10a and the honeycomb side 10B, and divides the honeycomb side 10B into four areas by the seventh rib 17 (the "cross" rib), each area forms 25 sub-areas (the "recess S"), and 21 other sub-areas (the "recess R, S") are spaced apart from each other by a plurality of ribs (the second rib 12, the third rib 13, the fourth rib 14, the fifth rib 15 and the sixth rib 16) in the "cross" rib, so that each sub-area has nine through holes 20, but the sub-areas (the "recess R") in the central portion of the "cross" rib do not form the through holes 20.

In the present embodiment, the positions of the plurality of through holes 20 are arranged corresponding to the plurality of 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, and the through holes 20 of each row are symmetrically arranged with respect to the cross-shaped auxiliary rib 18.

In summary, the heights h1, h3, h7 of the main ribs of the rib structure 1a relative to the honeycomb side 10b are at least 25 mm, so that the structural strength of the standard raised floor 1,2 is improved, and the standard raised floor 1,2 can bear heavier equipment in the semiconductor process, so as to avoid the problem of cracking of the standard raised floor 1,2 in use. Further, the heights h1 to h7 and the widths d1 to d7 of the ribs are adjusted according to the load-bearing sizes of the standard raised floors 1 and 2, that is, the heights h1 to h7 and the widths d1 to d7 of the ribs are smaller when the load-bearing sizes are smaller, so that the materials and the weight of the standard raised floors 1 and 2 are saved.

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

The above embodiments are merely illustrative of the principles of the present invention and its effectiveness, and are not intended to limit the invention. Modifications to the above would be obvious to those of ordinary skill in the art, without departing from the spirit and scope of the present invention. The scope of the invention is therefore intended to be indicated by the appended claims.
