Technical Field

The utility model 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 utility model is to provide a standard raised floor, which can avoid chipping.

The standard raised floor of the utility model 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, fourth, fifth and seventh ribs are used as main ribs with a height of at least 25 mm relative to the honeycomb side, and the third 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 third rib to the seventh rib relative to the honeycomb side, the sum of the heights of the first rib and the ceiling is 50 to 52 mm, and the thickness of the ceiling is 3 to 3.6 mm.

In the standard raised floor, the heights of the second rib, the fourth rib, the fifth rib and the seventh rib relative to the honeycomb side are 32 to 48.4 mm.

In the standard raised floor, the third and sixth ribs have a height of 17.5 to 18 mm relative to the honeycomb side.

In the standard raised floor, the width of the first rib is 7 to 8 mm.

In the standard raised floor, the widths of the second rib, the fourth rib, the fifth rib and the seventh rib are 3.2 to 5.5 mm.

In the standard raised floor, the width of the third and sixth ribs is 2.8 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 8 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.

Further advantages and effects of the present utility model will become apparent to those skilled in the art from the disclosure of the present utility model by the following specific examples.

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 utility model, which is defined by the appended claims, but rather by the appended claims. Also, the terms such as "upper", "left", "right" and "a" and the like are used in the present specification for convenience of description only, and are not intended to limit the scope of the present utility model, but rather to limit the relative changes or modifications thereof, without substantially changing the technical content, as the scope of the present utility model may be considered.

Fig. 1A, 1B, 1C and 1D are schematic views of a first embodiment of a standard raised floor 1 according to the present utility model. The standard raised floor 1 of the present embodiment is used to carry a heavy load, which carries a load of about 1200 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 3 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 sequentially 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 first, second, fourth, fifth and seventh ribs 11,12,14,15,17 are at least 25 mm (mm) relative to the height h1, h2, h4, h5, h7 of the honeycomb side 10B, and the third and sixth ribs 13,16 are lower than 25 mm relative to the height h3, h6 of the honeycomb side 10B, so that the first, second, fourth, fifth and seventh ribs 11,12,14,15,17 are main ribs, and the third and sixth ribs 13,16 are middle ribs, and the first to sixth ribs 11 to 16 are symmetrically distributed (or from the top to bottom as shown in fig. 1B) with respect to the seventh rib 17 (i.e. rib) and the fourth ribs 11,12,14,15,17 are symmetrically distributed between the fourth, fifth and seventh ribs 13,16 and the fifth ribs 13,16 are spaced by the fifth and seventh ribs 17 w, and the fifth ribs 17 are spaced apart by the fifth and the fifth ribs 17.

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 47 mm (equal to the height H2 of the second rib 12 relative to the honeycomb side 10 b) greater than the heights H3 to H7 of the third to seventh ribs 13 to 17 relative to the honeycomb side 10b, and 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 50 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 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 47 mm, the height h4 of the fourth rib 14 relative to the honeycomb side 10b is 32 mm, the height h5 of the fifth rib 15 relative to the honeycomb side 10b is 32 mm, the height h7 of the seventh rib 17 relative to the honeycomb side 10b is 44 mm, and the heights h3, h6 of the third and sixth ribs 13,16 relative to the honeycomb side 10b are 17.5 mm, wherein the two seventh ribs 17 in the longitudinal direction and the transverse direction 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 a recess R of another embodiment is formed at the central portion of the cross rib. Further, the thickness of the top board 10 in the recess 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 recess R is increased to 6 mm or the same as the thickness t0 of the top board 10, and the cross-shaped ribs 17a are disposed in the recess R, which have a height h0 of 13 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 7.5 mm, the width d2 of the second rib 12 is 4.5 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 mm, and the width d7 of the seventh rib 17 is 5.5 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 partial height h3, h6 of the rib structure 1a is also smaller, i.e. the height h3, h6 of the middle rib (third and sixth ribs 13, 16) is much smaller than the heights h1, h2, h4, h5, h7 of the main ribs (first, second, fourth, fifth and seventh ribs 11,12,14,15,17), 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 utility model. The standard raised floor 2 of the present embodiment is also used for carrying a heavier load, which carries about 1200 kg, and the difference from the first embodiment is that the rib structure 2a is additionally provided with the auxiliary ribs 28, so the same parts will not be described in detail below.

As shown in fig. 2A, 2B and 2C, the rib structure 2A is additionally provided with a plurality of auxiliary ribs 28 with a volume much smaller than that of other ribs, the height h8 (e.g. 3 mm) of the auxiliary ribs relative to the honeycomb side 20B is lower than the heights h3, h6 of the middle ribs relative to the honeycomb side 20B, and the width d8 is 3 mm. For example, a plurality of auxiliary ribs 28 are formed in each of the recesses S so as to extend in a single direction without being staggered with each other, and two parallel auxiliary ribs 28 are arranged in a single recess S as shown in fig. 2B.

In the present embodiment, the thickness T0 of the ceiling 20 is 3 mm, the height H1 of the first rib 21 relative to the honeycomb side 20B is 48 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 51 mm, and the total height H of the footstand 2B, the first rib 21 and the ceiling 20 is 56.5 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 48 mm, the height h4 of the fourth rib 24 relative to the honeycomb side 20b is 34.5 mm, the height h5 of the fifth rib 25 relative to the honeycomb side 20b is 34.5 mm, the height h7 of the seventh rib 27 relative to the honeycomb side 20b is 47 mm, and the heights h3, h6 of the third and sixth ribs 23,26 relative to the honeycomb side 20b are 17.5 mm. It should be appreciated that the heights h3, h6 of the remaining ribs h1, h2, h4, h5, h7 are increased except for the heights h3, h6 of the third and sixth ribs 23,26, which are the same as those of the first embodiment. On the other hand, the thickness of the ceiling board 20 at the recess R is increased to 6 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 11 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 mm, the width d2 of the second rib 22 is 4.2 mm, the width d3 of the third rib 23 is 3 mm, the width d4 of the fourth rib 24 is 3.2 mm, the width d5 of the fifth rib 25 is 3.2 mm, the width d6 of the sixth rib 26 is 3 mm, and the width d7 of the seventh rib 27 is 4.5 mm.

As can be seen from the above, the heights h3, h6 of the rib structure 2a are also smaller, i.e. the heights h3, h6 of the middle ribs (the third and sixth ribs 23, 26) are much smaller than the heights h1, h2, h4, h5, h7 of the main ribs (the first, second, fourth, fifth and seventh ribs 21,22,24,25,27), and the thickness t0 of the antenna plate 20 is 3 mm and the length L is 600 mm, and the thickness t1 of the wing plate 2d is 6 mm, which are the same as those of the first embodiment, even the specifications of the footstand 2b are the same, so as to facilitate saving materials and reducing weight.

Fig. 3A, 3B and 3C are schematic views of a third embodiment of a standard raised floor 3 according to the present utility model. The standard raised floor 3 of the present embodiment is also used for carrying a heavier load, which carries about 1200 kg, and the difference from the second embodiment is the local height change of the rib structure 3a, so the same parts will not be described in detail.

In the present embodiment, the thickness T0 of the ceiling 30 is 3.6 mm, the height H1 of the first rib 31 relative to the honeycomb side 30B is 48.4 mm, the height sum T of the first rib 31 and the ceiling 30 (i.e., the height of the first rib 31 relative to the ground side 30 a) is 52 mm, and the total height H of the foot rest 3B, the first rib 31 and the ceiling 30 is 55 mm, wherein the thickness T1 of the wing 3d is 6 mm, the first rib 31 is formed at the edge of the ceiling 30 to form a side rib of the standard raised floor 3 as a frame of the standard raised floor 3, and the first to sixth ribs 31 to 36 are symmetrically distributed on the left and right (or vertically as shown in fig. 3B) with respect to the seventh rib 37.

In the rib structure 3a, as shown in fig. 3C, the height h2 of the second rib 32 relative to the honeycomb side 30b is 48.4 mm, the height h4 of the fourth rib 34 relative to the honeycomb side 30b is 46.5 mm, the height h5 of the fifth rib 35 relative to the honeycomb side 30b is 46.5 mm, the height h7 of the seventh rib 37 relative to the honeycomb side 30b is 48 mm, and the heights h3, h6 of the third and sixth ribs 33,36 relative to the honeycomb side 30b are 18 mm. On the other hand, the thickness of the ceiling board 30 at the recess R is increased to 6.6 mm (i.e., greater than the thickness t0 of the ceiling board 30 at other locations), and the cross-shaped ribs 37a are disposed in the recess R, which have a height h0 of 10 mm (greater than the thickness t0 of the ceiling board 30) with respect to the honeycomb side 30b, so as to enhance the compressive strength of the standard raised floor 3 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. 3C. For example, the width d1 of the first rib 31 is 8 mm, the width d2 of the second rib 32 is 6 mm, the width d3 of the third rib 33 is 2.8 mm, the width d4 of the fourth rib 34 is 3.2 mm, the width d5 of the fifth rib 35 is 3.2 mm, the width d6 of the sixth rib 36 is 2.8 mm, and the width d7 of the seventh rib 37 is 4.2 mm.

The height h8 of the auxiliary rib 38 with respect to the honeycomb side 30b is 8 mm, and the width d8 thereof is 2.5 mm.

As can be seen from the above, the partial heights h3, h6 of the rib structures 3a are also smaller, i.e. the heights h3, h6 of the middle ribs (the third and sixth ribs 33, 36) are much smaller than the heights h1, h2, h4, h5, h7 of the main ribs (the first, second, fourth, fifth and seventh ribs 31,32,34,35,37), so as to facilitate saving materials and reducing weight.

Fig. 4A, 4B and 4C are schematic views of a fourth embodiment of a standard raised floor 4 according to the present utility model. The standard raised floor 4 of the present embodiment is also used for carrying a heavier load, which carries about 1500 kg, and the difference from the third embodiment is the local height change of the rib structure 4a, so the same parts will not be described in detail.

In the present embodiment, the thickness T0 of the ceiling plate 40 is 3 mm, the height H1 of the first rib 41 relative to the honeycomb side 40B is 48 mm, the height sum T of the first rib 41 and the ceiling plate 40 (i.e., the height of the first rib 41 relative to the ground side 40 a) is 51 mm, and the total height H of the footstand 4B, the first rib 41 and the ceiling plate 40 is 55 mm, wherein the thickness T1 of the wing plate 4d is 6 mm, the first rib 41 is formed at the edge of the ceiling plate 40 to be a side rib of the standard raised floor 4 to be a frame of the standard raised floor 4, and the first to sixth ribs 41 to 46 are distributed symmetrically (or vertically symmetrically as shown in fig. 4B) with respect to the seventh rib 47.

In the rib structure 4a, as shown in fig. 4C, the height h2 of the second rib 42 relative to the honeycomb side 40b is 47 mm, the height h4 of the fourth rib 44 relative to the honeycomb side 40b is 34.5 mm, the height h5 of the fifth rib 45 relative to the honeycomb side 40b is 34.5 mm, the height h7 of the seventh rib 47 relative to the honeycomb side 40b is 47 mm, and the heights h3, h6 of the third and sixth ribs 43,46 relative to the honeycomb side 40b are 17.5 mm. On the other hand, the thickness of the ceiling board 40 at the recess R is 6 mm (greater than the thickness t0 at other places), and the cross-shaped ribs 47a are disposed in the recess R, the height h0 of which with respect to the honeycomb side 40b is 11 mm (greater than the thickness t0 of the ceiling board 40), so as to improve the compressive strength of the standard raised floor 4 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. 4C. For example, the width d1 of the first rib 41 is 7 mm, the width d2 of the second rib 42 is 4 mm, the width d3 of the third rib 43 is 3 mm, the width d4 of the fourth rib 44 is 3.5 mm, the width d5 of the fifth rib 45 is 3.5 mm, the width d6 of the sixth rib 46 is 3 mm, and the width d7 of the seventh rib 47 is 4.5 mm.

The height h8 of the auxiliary rib 48 with respect to the honeycomb side 40b is 3 mm, and the width d8 thereof is 3 mm.

As can be seen from the above, the partial heights h3, h6 of the rib structures 4a are also smaller, i.e. the heights h3, h6 of the middle ribs (third and sixth ribs 43, 46) are much smaller than the heights h1, h2, h4, h5, h7 of the main ribs (first, second, fourth, fifth and seventh ribs 41,42,44,45,47), so as to facilitate saving materials and reducing weight.

Fig. 5A, 5B and 5C are schematic views of a fifth embodiment of a standard raised floor 5 according to the present utility model. 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. 5A and 5C, according to the first embodiment, the standard raised floor 5 forms a plurality of through holes 50 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 "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 50, but the sub-areas (the "recess R") in the central portion of the "cross" rib do not form the through holes 50.

In the present embodiment, the positions of the plurality of through holes 50 are arranged corresponding to the plurality of recesses S. For example, nine through holes 50 are formed in each recess S, and the nine through holes 50 are arranged in an array such that each row has three through holes 50.

Therefore, the recess R of the central portion of the seventh rib 17 (the # -shaped rib) may not be provided with the through hole 50, and the height h0 of the inner cross rib 17a with respect to the honeycomb side 10b is greater than the thickness t0 of the ceiling 10, so as to enhance the strength of the standard raised floor 5.

It should be appreciated that the standard raised floors 2,3,4 of the second through fourth embodiments may also have a plurality of perforations 50 formed in the recesses S thereof. For example, based on the second embodiment, the rows of perforations 50 are spaced apart by the auxiliary rib 28 such that each row has three perforations 50, as shown in fig. 5B.

In summary, the heights h1, h2, h4, h5, h7 of the main ribs of the rib structures 1a,2a,3a,4a relative to the honeycomb sides 10b,20b,30b,40b are at least 25 mm, so that the structural strength of the standard raised floor 1,2,3,4,5 is improved, and the standard raised floor 1,2,3,4,5 can bear heavier machine equipment in the semiconductor process, so as to avoid the problem of cracking of the standard raised floor 1,2,3,4,5 in use. Further, the heights h 1-h 7 and the widths d 1-d 7 of the ribs are adjusted according to the bearing loads of the standard raised floors 1,2,3,4,5, so that the materials of the standard raised floors 1,2,3,4,5 are saved, and the weight is reduced.

Furthermore, by means of the design of the auxiliary ribs 28,38,48, the structural strength of the standard raised floor 2,3,4 can be further improved.

The above embodiments are merely illustrative of the principles of the present utility model and its effectiveness, and are not intended to limit the utility model. 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 utility model. The scope of the utility model is therefore intended to be indicated by the appended claims.
