Description
DECK PLATE FOR SLABS
Technical Field
[1] The present invention relates to a deck plate for slabs of various buildings, and more particular, to a deck plate for slabs which is capable of withstanding a bending force or a deflection stress of the slabs after curing concrete, while functioning as a concrete framework when manufacturing slabs of a building, and which is constructed such that it comprises a plurality of grooves each whose cross-section is formed in a hexagonal shape so as to be opened downwardly at a lower side thereof, the grooves being arranged in the lengthwise direction of the deck plate, so that noise can be irregularly reflected or absorbed by the plurality of grooves, thereby blocking noises generated in a room so as to reduce an interlay er propagation of noises. Background Art
[2] Generally, when manufacturing a concrete framework of slabs for various buildings, especially for steel structures, conventional deck plates have had bottom surfaces of various shapes so as to serve a framework of the slabs and withstand a bending force or a deflection stress of the slabs after curing concrete, to thereby reinforce the steel structures.
[3] As shown in FlG. 7, a slab 4 has been completed using conventional deck plate 1 having a concavo-convex part 2' whose cross-section is formed in a trapezoidal shape, the concavo-convex part 2' being formed on the deck plate 1 in the lengthwise direction thereof. Thereafter, a fixed rod 6a is coupled to an anchor 5 inwardly fixed on the deck plate so as to allow a ceiling board 6 to be fixed to the deck plate 1, or otherwise, a free end of the fixed rod 6a is directly welded and fixed to the deck plate 1. However, in case of a fixing method using the anchor 5, the anchor 5 has to be fixed to the deck plate 1 one by one through a welding operation and the like when manufacturing the framework of the slab, thereby causing troublesomeness in the operation as well as taking considerable time for the operation. In case of a welding and fixing method, a worker has to perform a welding operation one by one watching the ceiling, thereby creating a danger of an accident during the welding operation and taking considerable time for the operation as well as causing troublesomeness in the operation. Further, in case where a separate ceiling board is not installed, there occurs a shortcoming in that the ceiling(bottom surface of the slabs) looks like untidy due to the concavo-convex parts 2', to thereby the external appearance to be deteriorated.
[4] Further, although noises are irregularly reflected by the deck plate 1 to thereby allow the interlayer propagation of noises to be partially blocked when noise is generated in a room, the reflected noises are kept remained in a room and the remaining noises are raised up again to the ceiling, to thereby permit the noise to pass through the slabs 4 and to be propagated, thus failing in a fundamental blocking and absorbing of noise.
[5] In addition, the shape of the conventional deck plate 1 is formed such that the deck plate 1 includes a concavo-convex part 2' whose cross-section is formed in a trapezoidal shape described above, a "D" shape or the like so as to enhance a combining force with concrete as well as enhance a strength of the deck plate 1, or formed such that protrusions or reinforcing ribs are mounted on the concavo-convex part 2' in such a manner as to be spaced apart by a predetermined interval from each other, but there occur problems in that manufacturing cost and time are considerably increased due to the technical sophistication of the manufacturing device for the conventional deck plate 1 as well as additional molding processes. Thus, the need exists for the deck plate enable to improve the above problems. Disclosure of Invention Technical Problem
[6] Accordingly, the present invention has been made to solve the above problems occurring in the prior art, and it is an object of the present invention to provide a deck plate for slabs obtained by positively improving a typical deck plate which has a concavo-convex part formed thereon in the lengthwise direction thereof, wherein the improvement comprises: a plurality of grooves each whose cross-section is formed in a hexagonal shape so as to be opened downwardly at a lower side thereof, the groove being arranged in the lengthwise direction of the deck plate in such a manner as to be spaced part by a predetermined interval from each other; and a plurality of double-row grooves each arranged between adjacent two grooves, each double-row groove being formed such that two grooves are placed on top each other to form a double-row pattern, so that a strength of the deck plate can be maximized, noises generated in a room can be irregularly reflected and simultaneously absorbed by the plural grooves to thereby execute the fundamental blocking of the noise, and installation of a ceiling board can be facilitated. Technical Solution
[7] To accomplish the above object, according to the present invention, there is provided a deck plate for slabs which has a concavo-convex part of various shapes formed thereon in the lengthwise direction thereof, wherein the improvement comprises: a plurality of grooves arranged transversely thereon along the lengthwise direction of the deck plate, each groove whose cross-section is formed in a hexagonal shape to have an opening opened downwardly at a lower side thereof and an expanded part formed over the opening in such a manner that its width is larger than that of the opening; and a plurality of double-row grooves each arranged between adjacent two grooves, each double-row groove being formed such that two grooves are placed on top each other to form a double-row pattern so as to communicate therewith via a connection opening, wherein the grooves and the double-row grooves are alternatively arranged thereon at equal intervals. Advantageous Effects
[8] According to the present invention, the deck plate for slabs of the invention comprises a plurality of grooves each whose cross-section is formed in a hexagonal shape to have an opening opened downwardly at a lower side thereof and an expanded part formed over the opening; and a plurality of double-row grooves each arranged between adjacent two grooves, each double-row groove being formed such that two grooves are placed on top each other to form a double-row pattern, so that the plural grooves and double-row grooves are alternatively mounted on the deck plate at equal intervals in the lengthwise direction thereof, thereby maximizing the strength of the deck plate against bending or deflection stress of the slabs, as well as irregularly reflecting and absorbing an indoor noise by means of the hexagonal shaped-grooves and double-row grooves. In this regard, when the ceiling board, electric wires, fire- extinguishing piping and the like are supported by the deck plate, the deck plate may facilitate their execution, enhance a supporting force against them, and have its excellent external appearance. Brief Description of the Drawings

[15]
Mode for the Invention
[16] FIGs. 1 and 2 are a perspective view of a preferred embodiment of the present invention and a bottom perspective view of the present invention, respectively. Figs. 3 and 4 are cross-sectional configuration views of an embodiment in which the present invention is applied to slabs. Figs. 5 and 6 are magnified cross-sectional views showing an exemplary main part of the present invention and another exemplary main part of the present.
[17] Hereinafter, a preferred embodiment of the invention will be explained in detail with reference to the appended drawings. In the drawings, the same reference numerals are used to designate the same components of the conventional art.
[18] The present invention is featured in that it is obtained by improving a typical deck plate 1 having a concavo-convex part of various shapes formed thereon in the lengthwise direction thereof, wherein the improvement comprises a plurality of grooves 2 arranged transversely thereon along the lengthwise direction of the deck plate 1.
[19] The plurality of grooves 2 are constructed such that their cross-section is formed in a hexagonal shape to have an opening 2a opened downwardly at a lower side thereof and an expanded part 2b formed over the opening 2a in such a manner that its width is larger than that of the opening 2a.
[20] A plurality of double-row grooves 3 are formed such that two grooves 2 are placed on top each other to form a double-row pattern and each double-row groove 3 is arranged between adjacent two grooves 2. At this time, as shown in Fig. 5, an above groove 2 and a below groove 2 of the double-row groove 3 are basically constructed such that they communicates with each other via a connection opening 3a, or constructed such that both side walls of the connection opening 3a are joined to each other to thereby be welded and fixed, as shown in Fig. 6.
[21] Of course, the cross-section of each groove 2 may be designed and modified to be formed in various shapes so as to have an opening 2a and an expanded part 2b, although it is formed in a hexagonal shape according to the invention.
[22] Further, a girder is fixed on the bottom portion of the deck plate 1, so that the deck plate 1 is imaginably fixed to an upper and lower steel bars 4a, 4b of a slab 4. Here, a separate drawing or description for the girder is omitted, since a typical girder disclosed and widely used is employed.
[23] Reference numeral 6b and 7 of the drawings which have not been described denote a supporting frame to which a ceiling board 6 is installed and a fixing clip for coupling a fixing rod 6a for fixing the ceiling board 6 to the deck plate 1, respectively.
[24] The deck plate of the present invention having the construction described above is integrally adhered on a bottom surface of a slab 4 of various buildings, as shown in Figs. 3 and 4. When manufacturing a framework for molding the slab 4, the deck plate is fixed to the upper and lower steel bars 4a, 4b by means of the girder, and is fixed to the ceiling board 6 after pouring and curing concrete, if necessary. Another free end of the fixing rod 6a fixed to the supporting frame 6b, to which the ceiling board 6 is installed, is positioned inside of the expanded part 2b of the groove 2 or the double- row groove 3 and mounted by means of the fixing clip 7 caught by the opening 2a.
[25] The plural grooves 2 and double-row grooves 3 may allow the strength of the deck plate 1 against bending or deflection stress of slabs to be maximized. Further, the grooves 2 arranged in the lengthwise direction thereof are formed such that their cross- section is formed in a hexagonal shape, so that when the noise generated in a room is propagated to the inside of the grooves 2 via the opening 2a, an irregular reflection of the noise occurs inside of the expanded part 2b, thereby preventing the propagation of the noise, thus allowing the noise to be absorbed. The plural double-row grooves 3 also have the identical effects as in the grooves 2 and the noise absorption is achieved in double manner via the above and below grooves.
[26] Further, the grooves 2 and the double-row grooves 3 are alternately formed at equal intervals on the deck plate 1 of the invention, thus the deck plate 1 is excellent in terms of its structural performance in comparison with that of the conventional deck plate 1 having a typical concavo-convex part arranged thereon. Also, when the ceiling board 6, the supporting frame 6b, electric wires, fire-extinguishing piping and the like are supported by means of the grooves of the invention, they are readily and securely supported using the fixing clip 7 without the need for the anchor 5 or any welding operation, to thereby facilitate their execution and enhance a supporting force against them.
[27] In addition, in case where a separate ceiling board 6 is not installed, the deck plate 1 of the invention is excellent in its external appearance in comparison with that of the conventional deck plate 1, since only the openings formed at equal intervals 2a are shown when looking up a ceiling in a room.
[28] The deck plate 1 may be diversely used for the slabs 4 of steel structures and reinforced concrete structures such as high-rise buildings, factories, or warehouses and the like, and an iron plate galvanized on its surface may be preferably employed as a deck plate. Industrial Applicability
[29] As described above, the deck plate 1 for slabs 4 of the invention comprises a plurality of grooves 2 each whose cross-section is formed in a hexagonal shape to have an opening 2a opened downwardly at a lower side thereof and an expanded part 2b formed over the opening 2a; and a plurality of double-row grooves 3 each arranged between adjacent two grooves 2, each double-row groove being formed such that two grooves 2 are placed on top each other to form a double-row pattern, so that the plural grooves 2 and double-row grooves 3 are alternatively mounted on the deck plate 1 at equal intervals in the lengthwise direction thereof, thereby maximizing the strength of the deck plate against bending or deflection stress of the slabs 4, as well as irregularly reflecting and absorbing an indoor noise by means of the hexagonal shaped-grooves 2 and double-row grooves 3. In this regard, when the ceiling board 6a, electric wires, fire-extinguishing piping and the like are supported by the deck plate 1, the deck plate 1 may facilitate their execution, enhance a supporting force against them, and have its excellent external appearance.
[30] While the present invention has been described with reference to the particular illustrative embodiments, it is not to be restricted by the embodiments but only by the appended claims. It is to be appreciated that those skilled in the art can change or modify the embodiments without departing from the scope and spirit of the present invention.
