Description
- Pursuant to 35 U.S.C. § 119(a), this application claims the benefit of earlier filing date and right of priority to Korean Application No. 2005-69402, filed on Jul. 29, 2005, the contents of which is hereby incorporated by reference herein in its entirety.
- The present invention relates to a high-strength panel for use as flooring in a clean facility, such as a semiconductor clean room.
- As is well known to those skilled in the art, a clean room in which a variety of special experimental and production equipment are mounted, utilizes a double flooring system. Examples of such clean rooms include a production room for highly integrated circuits such as semiconductors and a genetic engineering laboratory. The double flooring system is constructed with a predetermined height in order to uniformly distribute the load of the variety of special equipment while effectively absorbing and removing exterior dust particles, fine particulates, and the like to thereby prevent the generation of cracks or depressions in the floor even when the load is concentrated on a specific location of the double flooring system.
- When the double flooring system is used at certain locations where permeation of cold air into the flooring system, or overheating of the flooring system caused by heat produced from special machinery must be prevented, or at places requiring an adjustment in the temperature and humidity of the room and an absorption and removal of dust particles, fine particulates and the like, the double flooring system may include a porous panel possessing a number of fine pores. An underside of the porous panel forms a floor having a supporting structure. Due to a variety of exhaust devices and cable equipment being mounted underneath the floor, the floor, being the bottom surface of a semiconductor clean room, must be spaced apart from the ground by a certain constant height. Considering the size of the exhaust devices and cable equipment and other various conditions, the installation height of the floor must have variability.

rim ribs 316, which formrim portions 302 of a high-strength panel 30 (as shown inFIGS. 3 and 6 ), have increased thickness as compared to a conventional panel. Eachrim rib 316 further has a tapered surface. - Furthermore, the
rim ribs 316 of therim portions 302, which support four corners of thepanel 30, are reinforced in consideration of a higher height of the ribs. Accordingly, resistance against initial deformation is increased. Moreover, because of a thicker thickness of the ribs, critical strength to sustain a breaking load is enhanced. Also, the presence of the tapered surface allows therim ribs 316 to achieve a uniform initial deformation value and breaking strength at any location thereof. - In one aspect of the present invention, a plurality of auxiliary reinforcing
ribs 307 as shown inFIGS. 3, 4 , 6 and 8, are arranged in respective lattice sections defined by a main reinforcingrib 306. Preferably, theauxiliary reinforcing ribs 307 have half the height of the main reinforcingrib 306, and are arranged to divide a respective one of the lattice sections into 4 rows and 4 columns. That is, each lattice section defined by the main reinforcingrib 306 is divided into sixteen sub-sections by theauxiliary reinforcing ribs 307. - Preferably, each sub-section, defined by the
auxiliary reinforcing ribs 307, is formed at a lower surface thereof withcircular recesses 308 in a 2×2 array. Thecircular recesses 308 are diagonally aligned to minimize the area of a recess defined therebetween. Also, acircular rib 314 surrounds eachcircular recess 308, as shown inFIGS. 4, 7 and 8. With this configuration, a supporting force of thepanel 30 resistant to the vertical load and eccentric load is enhanced, and a degradation of the supporting force at a specific location of thepanel 30 is prevented. - Therefore, by virtue of the
rim ribs 316 and the auxiliary reinforcingribs 307 inside the main reinforcingrib 306, thepanel 30 of the present invention achieves an enhanced supporting force resistant to the vertical and eccentric loads and prevents a degradation of the supporting force at a specific location thereof. - Referring to
FIGS. 4, 7 and 8, the plurality ofcircular recesses 308, which are surrounded by the respectivecircular ribs 314, are formed at abottom layer 310 of each sub-section defined by the respectiveauxiliary reinforcing ribs 307. - As shown in
FIG. 6 , the height of the auxiliary reinforcingribs 307 is preferably approximately ½ to ⅓ the height of the main reinforcingrib 306. - Such a height of the auxiliary reinforcing
ribs 307 is determined in consideration of the material costs of the entire panel as well as a panel supporting force effective to resist the vertical and eccentric loads. Thus, an excessively high height of the auxiliary reinforcingribs 307 beyond the above range is economically undesirable because it results in an increase in the price of products. - Meanwhile, with respect to the
circular recesses 308 in accordance with the present invention, the thicker the thickness of thecircular rib 314 that encloses a respective one of thecircular recesses 308, the supporting force resistant to the vertical and eccentric loads is increased. - As shown in
FIG. 7 , thecircular recesses 308, formed at the lower surface of the high-strength panel 30, are diagonally spaced apart, rather than being vertically and horizontally spaced apart, from one another. In this case, the respective adjacent fourcircular recesses 308 in a 2×2 array define a diamond-shaped supportingrecess 312 in the center thereof. The diamond-shaped supportingrecess 312 is better at enhancing the supporting force while keeping the original shape of thecircular recesses 308. Preferably, a diagonal length of the diamond-shapedrecess 312 is shorter than a diameter of thecircular recess 308. - In the present invention, the
rim portions 302 of the supportingpanel 30 are centrally formed with a predetermined number ofrim lattice sections 303, as shown inFIGS. 3 and 6 . Each of therim lattice sections 303 contains theauxiliary reinforcing ribs 307 which divide thelattice section 303 into four sub-sections. - As is apparent from the above description, the high-strength panel of the present invention is configured such that rim ribs are formed along the rim of the panel and a plurality of auxiliary reinforcing ribs are arranged in a respective one of lattice sections defined by a main reinforcing rib so as to provide the entirety of the panel with a supporting force for effectively increasing the strength of the panel resistant to a concentrated load. Further, according to the present invention, since a plurality of circular recesses is formed at a lower surface of the panel and is surrounded by circular ribs, respectively, it is possible to effectively support vertical and eccentric loads applied to the entirety of the panel while preventing the downwardly applied load from being concentrated at a specific location of the panel by distributing the load throughout the panel.
- Although the bottom supporting panel according to the preferred embodiment of the present invention has been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications of the present invention, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
