Description

Standard elevated floor

Technical Field

The invention relates to a floor, 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 standard raised floor of the invention comprises: 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 sequentially defined with a first rib, a second rib, a third rib, a fourth rib, a fifth rib, a sixth rib and a seventh rib from the edge of the antenna plate to the middle, and the first, second, third, fifth and seventh ribs are used as main ribs with a height of at least 25 mm relative to the honeycomb side, and the fourth and sixth ribs are used as middle ribs with a height of less than 25 mm relative to the honeycomb side.

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 is 38 to 58 mm, and the thickness of the ceiling is 2.5 mm.

In the standard raised floor, the heights of the second rib, the third rib, the fifth rib and the seventh rib are 25 to 45 mm relative to the honeycomb side.

In the standard raised floor, the height of the fourth and sixth ribs is 12 to 18 mm with respect to the honeycomb side.

In the standard raised floor, the width of the first rib is 7.5 mm.

In the standard raised floor, the widths of the second rib, the third rib, the fifth rib and the seventh rib are 2.5 to 5.3 mm.

In the standard raised floor, the width of the fourth and sixth ribs is 2.5 to 3 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 a single direction without being staggered with each other. Alternatively, the auxiliary rib has a height of 3 to 5 mm with respect to the honeycomb side and a width of 2.5 to 3 mm.

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 is formed with two ribs in longitudinal and transverse directions to divide the standard raised floor into four regions, 25 subregions are formed between the adjacent second ribs, third ribs, fourth ribs, fifth ribs and sixth ribs in the four regions, each subregion is provided with a concave part, the first ribs to the sixth ribs are symmetrically distributed based on the ribs in the shape of the Chinese character jing, the other concave part is formed at the central part of the ribs in the shape of the Chinese character jing formed by the seventh ribs, an auxiliary rib or a cross rib is arranged in the concave part, and a wing plate is formed around the ceiling, so that the height of the auxiliary rib or the height of the cross rib and the thickness of the wing plate are larger than the thickness of the ceiling, and the strength of the standard raised floor at the middle part is improved. For example, 21 other sub-regions are separated from each other by the second rib, the third rib, the fourth rib, the fifth rib and the sixth rib, and nine through holes are formed in each sub-region, but the through holes are not formed in the sub-region at the central portion of the cross rib.

Therefore, in the standard 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 that the structural strength of the standard raised floor is improved, and compared with the prior art, the standard raised floor can bear heavier machine equipment in the semiconductor process, 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 and 1D 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 relatively heavy load, which carries a load of about 1000 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 only shows the longitudinal rib structures 1a, and the transverse rib structures 1a are identical to the longitudinal rib structures 1a, so the cross section of the transverse rib structures 1a is omitted.

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 2.5 mm, and a wing board 1d (with a thickness t1 of 6 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 with an L-shaped convex (or L-shaped concave) bottom 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 from the edge of the ceiling 10 to the middle (or from the left to the right to the middle as shown in fig. 1B and 1C), wherein the heights h1 to h3, h5, h7 of the first to third ribs 11 to 13,15,17 relative to the honeycomb side 10B are at least 25 mm (mm), and the heights h4, h6 of the fourth and sixth ribs 14,16 relative to the honeycomb side 10B are lower than 25 mm, so that the first to third ribs 11 to 13,15,17 are used as main ribs, and the fourth and sixth ribs 14,16 are used as middle ribs, wherein the first to sixth ribs 11 to 16 are symmetrically distributed in a left-right direction (or from the upper to lower direction as shown in fig. 1B) with respect to the seventh ribs 17 (cross ribs) and the distances between the fourth ribs 14,16 and the fourth ribs 14,16 are at least 48 w, 15, 17.

In this embodiment, the first rib 11 and the second rib 12 are formed at the edge of the top plate 10 to serve as a frame for fixing the base 1b. For example, the first rib 11 and the second rib 12 are equal in height, the sum of the heights of the first rib 11 and the ceiling board 10 (i.e., the height of the first rib 11 relative to the ground side 10 a) is 38 mm, and the total height H of the footstand 1b, the first rib 11 and the ceiling board 10 is 40 mm, and the first rib 11 is formed at the edge of the ceiling board 10 to form a side rib of the standard type raised floor 1, so as to serve as a frame of the standard type raised floor 1 for fixedly connecting the footstand 1b. For example, the height H1 of the first rib 11 relative to the honeycomb side 10b is 35.5 mm 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 38 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 40 mm.

Furthermore, the heights h2 to h7 of the second to seventh ribs of the rib structure 1a may be the same or different as required, as shown in fig. 1C. For example, the height h2 of the second rib 12 relative to the honeycomb side 10b is 35 mm, the height h3 of the third rib 13 relative to the honeycomb side 10b is 35 mm, the height h5 of the fifth rib 15 relative to the honeycomb side 10b is 35 mm, the height h7 of the seventh rib 17 relative to the honeycomb side 10b is 35 mm, and the heights h4, h6 of the fourth and sixth ribs 14,16 relative to the honeycomb side 10b are 18 mm, wherein the two seventh ribs 17 in the longitudinal and transverse directions form a cross rib to divide the standard raised floor 1 into four regions, 25 sub-regions are formed between 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-region has a recess S, and the recess R of another embodiment is formed at the center of the cross rib. Further, the thickness of the top board 10 in the recess R may be larger than the thickness t0 of the top board 10 at other positions or the same as the thickness t0 of the top board 10 according to the requirement, and two parallel auxiliary ribs 17a are disposed in the recess R to increase the compressive strength of the standard raised floor 1 at the middle position.

In addition, the widths d 1-d 7 of the ribs may be the same (e.g., the second-sixth ribs 12-16) or different, as shown in FIG. 1C. For example, the width d1 of the first rib 11 is 7.5 mm, the width d2 of the second rib 12 is 3 mm, the width d3 of the third rib 13 is 3 mm, the width d4 of the fourth rib 14 is 3 mm, the width d5 of the fifth rib 15 is 3 mm, the width d6 of the sixth rib 16 is 3 mm, and the width d7 of the seventh rib 17 is 4.8 mm.

In addition, the rib structure 1a may be additionally provided with a plurality of auxiliary ribs 17a,18 with a volume far smaller than that of other ribs, as shown in fig. 1C, wherein the height h0, h8 (e.g. 6 mm) of the auxiliary ribs relative to the honeycomb side 10b is lower than the heights h4, h6 of the middle ribs relative to the honeycomb side 10b, and the width d8 is 3 mm. For example, a plurality of auxiliary ribs 17a,18 are formed in each of the recesses R, S so as to extend in a single direction without being staggered with each other, and two parallel auxiliary ribs 17a,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 ceiling 10 of the standard raised floor 1 is smaller, and the partial heights h4, h6 of the rib structures 1a are also smaller, i.e. the heights h4, h6 of the middle ribs (the fourth and sixth ribs 14, 16) are much smaller than the heights h1, h2, h3, h5, h7 of the main ribs (the first, second, third, fifth and seventh ribs 11,12,13,15,17), so as to facilitate saving materials and reducing weight.

Fig. 2A, 2B and 2C are schematic views of a second embodiment of a standard raised floor 2 according to the present invention. The standard raised floor 2 of the present embodiment is also used for carrying a heavier load, which carries about 1000 kg, and is different from the first embodiment in that the local height of the rib structure 2a is changed, so the description thereof will not be repeated.

In the present embodiment, the thickness T0 of the ceiling 20 is 2.5 mm, the height H1 of the first rib 21 relative to the honeycomb side 20B is 55.5 mm, the height sum T of the first rib 21 and the ceiling 20 (i.e., the height of the first rib 21 relative to the ground side 20 a) is 58 mm, and the total height H of the foot stand 2B, the first rib 21 and the ceiling 20 is 60 mm, wherein the thickness T1 of the wing plate 2d is 6 mm, the first rib 21 is formed at the edge of the ceiling 20 to be a side rib of the standard raised floor 2 as a frame of the standard raised floor 2, and the first to sixth ribs 21 to 26 are symmetrically distributed on the left and right (or vertically as shown in fig. 2B) with the seventh rib 27 as a reference.

In the rib structure 2a, as shown in fig. 2C, the height h2 of the second rib 22 relative to the honeycomb side 20b is 25 mm, the height h3 of the third rib 23 relative to the honeycomb side 20b is 25 mm, the height h5 of the fifth rib 25 relative to the honeycomb side 20b is 32 mm, the height h7 of the seventh rib 27 relative to the honeycomb side 20b is 45 mm, and the heights h4, h6 of the fourth and sixth ribs 24,26 relative to the honeycomb side 20b are 12 mm. On the other hand, the thickness of the ceiling board 20 at the recess R is increased by 5.5 mm (i.e., greater than the thickness t0 of the ceiling board 20 at other locations), and the cross-shaped ribs 27a are disposed in the recess R, and the height h0 of the cross-shaped ribs relative to the honeycomb side 20b is 13 mm (greater than the thickness t0 of the ceiling board 20) to increase the compressive strength of the standard raised floor 2 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. 2C. For example, the width d1 of the first rib 21 is 7.5 mm, the width d2 of the second rib 22 is 3 mm, the width d3 of the third rib 23 is 2.5 mm, the width d4 of the fourth rib 24 is 2.5 mm, the width d5 of the fifth rib 25 is 3 mm, the width d6 of the sixth rib 26 is 2.5 mm, and the width d7 of the seventh rib 27 is 5.3 mm.

The height h8 of the auxiliary rib 28 with respect to the honeycomb side 20b is 3 mm, and the width d8 thereof is 2.5 mm.

As can be seen from the above, the partial heights h4, h6 of the rib structure 2a are also smaller, i.e. the heights h4, h6 of the middle ribs (the fourth and sixth ribs 24, 26) are much smaller than the heights h1, h2, h3, h5, h7 of the main ribs (the first, second, third, fifth and seventh ribs 21,22,23,25,27), so as to facilitate saving materials and reducing weight.

Fig. 3A, 3B, 3C and 3D are schematic views of a third embodiment of a standard raised floor 3 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. 3A, 3B, 3C and 3D, according to the first embodiment, the standard raised floor 3 forms a plurality of through holes 30 on the ceiling 10, which are connected to the ground side 10a and the honeycomb side 10B, and the seventh rib 17 (the "cross" rib) divides the honeycomb side 10B into four areas, each of which forms 25 sub-areas (the recess S), and 21 other sub-areas (the recesses 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) such that each sub-area has nine through holes 30, but the sub-areas (the recesses R) at the central portion of the "cross" rib do not form the through holes 30.

In the present embodiment, the positions of the plurality of through holes 30 are arranged corresponding to the plurality of recesses S. For example, nine through holes 30 are formed in each recess S, and the nine through holes 30 are arranged in an array, and the auxiliary ribs 18 separate the through holes 30 in each row so that each row has three through holes 30.

Therefore, the recess R of the central portion of the seventh rib 17 (the # -shaped rib) may not be provided with the through hole 30, and the height h0 of the inner auxiliary rib 17a or the cross-shaped rib 27a with respect to the honeycomb side 10b is greater than the thickness t0 of the ceiling plate 10, so as to enhance the strength of the standard raised floor 3.

It should be understood that the standard raised floor 2 of the second embodiment may also have a plurality of through holes 30 formed in the recess S thereof.

In summary, the heights h1, h2, h3, h5, h7 of the main ribs of the rib structures 1a,2a relative to the honeycomb sides 10b,20b are at least 25 mm, so that the structural strength of the standard raised floor 1,2,3 is improved, and the standard raised floor 1,2,3 can bear heavier machine equipment in the semiconductor process, so as to avoid the problem of cracking of the standard raised floor 1,2,3 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 1,2 and 3, so that the materials and the weight of the standard raised floors 1,2 and 3 are saved.

Furthermore, by means of the design of the auxiliary ribs 18,28, the structural strength of the standard raised floor 1,2,3 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.
