Description
STRUCTURE FOR REINFORCING A CORRUGATED STEEL
PLATE
Technical Field
[1] The present invention relates to a corrugated steel plate that is typically used in construction work, and more particularly, to a structure for reinforcing a corrugated steel plate, including a plurality of connection means that are provided to one side of the corrugated steel plate and a plurality of bolts that are alternatively connected to the connection means for enhancing the bonding force between the corrugated steel plate and concrete. Background Art
[2] Typically, a corrugated steel plate is a structure for construction work in which a steel plate of thickness of 3.2 mm to 7 mm is corrugated to enhance rigidity thereof.
[3] A method of fabricating a structure for construction work using this type of corrugated steel plate has been disclosed in the Korean laid-open publication No.2000-16602(publishing date: March 25, 2000).
[4] In the following, a description of a structure for construction work using the corrugated steel plate will be made referring to the drawings.
[5] FIG. 7 is a sectional view showing a corrugated steel plate in a state of use according to the prior art.
[6] As shown in FIG. 7, a conventional reinforcing structure of a corrugated steel plate is configured to enhance the bonding force between a corrugated steel plate 120 and concrete 140, wherein a stud 150 is connected to the corrugated steel plate 120. Here, when a stud 150 made of metal is connected to one side of the corrugated steel plate 120 and then a predetermined current is applied thereto, an arc is produced on a connection part, thereby producing predetermined heat to a surface thereof. As a result, an end of the stud 150 is melted down to be welded to the one side of the corrugated steel plate 120. Accordingly, the lower end of the stud 150 is welded to a surface of the corrugated steel plate 120 and thus the stud 150 is configured to be stand on a surface of the corrugated steel plate 120. In this state, the corrugated steel plate 120 is subject to plating and drying processes for preventing corrosion. At this time, in case the corrugated steel plate 120 is subject to plating and then the stud 150 is welded thereto, the stud 150 is not welded smoothly to the corrugated steel plate 120 due to the plating film. In addition, though after the stud 150 is welded to the corrugated steel plate 120, the plating film on the welding part may bread off and corrosion thereto may occur. Accordingly, after welding the stud 150 to the corrugated steel plate 120, a plating
process has to be performed.
[7] Meanwhile, referring to fabricating a structure for construction work 100 using a conventional corrugated steel plate 120 as described above, a predetermined amount of concrete is poured onto the outside of the corrugated steel plate 120. At this time, the stud 150 is placed between the concrete 140 poured and the corrugated steel plate 120 and then the concrete 140 gradually becomes rigid, thereby bonding securely the stud 150 to the concrete 140. Therefore, the structure for construction work 100 including the corrugated steel plate 120 and the concrete 140 can be kept in a state that it is configured securely.
[8] However, referring to a conventional corrugated steel plate 120, since the stud 150 is welded, and then plating and drying processes are performed, a structure for construction work is transferred or stored in a state in which the stud 150 and the corrugated steel plate 120 stand. As a result, the following problems from the configuration arise.
[9] First, when the corrugated steel plate 120 is stacked and transferred for the relevant process, the corrugated steel plate 120 has to be spaced during stacking and transportation due to the long stud 150, which makes it unstable. In addition, the corrugated steel plate 120 is deformed due to bending, etc., and thus it has been difficult to transport the corrugated steel plate that is stacked.
[10] Second, there has to be provided a wide space for storing the corrugated steel plate
120.
[11] Third, in transporting the corrugated steel plate 120 to construction site, there has to be provided a predetermined space for stacking it on a transportation means, and thus it increases distribution cost. Disclosure of Invention Technical Problem
[12] A object of the present invention to solve the above-described problems is to provide a structure for reinforcing a corrugated steel plate for enhancing the bonding force between the corrugated steel plate and concrete and reducing the space for stacking and storing a large quantity of the corrugated steel plate. Technical Solution
[13] In order to achieve the above object, the present invention provides a structure for reinforcing a corrugated steel plate comprising: a plurality of connection means that are provided to one side of the corrugated steel plate and a plurality of bolts that are alternatively connected to the connection means for enhancing the bonding force between the corrugated steel plate and concrete.
[14] Preferably, the connection means is a nut that is welded to the one side of the
corrugated steel plate. [15] In addition, preferably, the connection means is a thread hole that is formed through the corrugated steel plate. [16] Additionally, preferably, the connection means is a fitting hole that is formed on one side of the corrugated steel plate such that the diameter thereof is smaller than that of the bolt body for an interference fit, and the diameter thereof increases gradually toward the other side of the corrugated steel plate. [17] Furthermore, a jaw is formed on the end of the bolt.
Advantageous Effects
[18] As described above, according to the present invention, the stacking and storing of a large quantity of the corrugated steel plate can be made easily without deforming thereof and thus transportation costs can be reduced significantly.
Brief Description of the Drawings [19] FIG. 1 is a perspective view showing a corrugated steel plate and a reinforcing structure thereof according to a first preferred embodiment of the present invention; [20] FIG. 2 is a cross sectional view showing the corrugated steel plate that is stacked, as shown in FIG. 1 ; [21] FIGs. 3 and 4 are views showing the corrugated steel plate in a state of use, as shown in FIG. 1 ; [22] FIG. 5 is a cross sectional view showing a corrugated steel plate and a reinforcing structure thereof according to a second preferred embodiment of the present invention; [23] FIG. 6 is a cross sectional view showing a corrugated steel plate and a reinforcing structure thereof according to a third preferred embodiment of the present invention; and [24] FIG. 7 is a cross sectional view showing a corrugated steel plate in a state of use according to the prior art.

Mode for the Invention [29] In the following, a structure for reinforcing a corrugated steel plate according to the present invention will be described in detail referring to the accompanying drawings. [30] FIG. 1 is a perspective view showing a corrugated steel plate and a reinforcing structure thereof according to a first preferred embodiment of the present invention,
FIG. 2 is a cross sectional view showing the corrugated steel plate that is stacked, as shown in FIG. 1, and FIGs. 3 and 4 are views showing the corrugated steel plate in a
state of use, as shown in FIG. 1.
[31] As shown in FIGs. 1 to 4, the structure for reinforcing a corrugated steel plate 12 according to the first preferred embodiment includes a nut 21 that is welded to the corrugated steel plate 12 and a bolt 50 that is fastened alternatively to the nut 21.
[32] That is, a plurality of nuts 21 are welded to one side of the corrugated steel plate 12 and then corresponding bolts 50 are fastened to the nuts 21. At this time, the corrugated steel plate 12 is subject to a plating process in a state that the nut 21 and bolt 50 are connected to each other such that corrosion to a connecting part can be prevented.
[33] Meanwhile, referring to an operation of the structure for reinforcing a corrugated steel plate as configured above, as shown in FIG. 2, a plurality of the corrugated steel plates 12 can be stacked and stored in a state that the nuts 21 are connected thereto. The height of the nut 21 that is welded to the corrugated steel plates 12 is not so high that when a plurality of the corrugated steel plate 12 are stacked, a stacking space therefor need not to be wide. Accordingly, a plurality of the corrugated steel plates 12 with nut 21 welded thereto can be efficiently stored without a wide space. In addition, in case a plurality of the corrugated steel plates 12 is stacked, a deformation of the corrugated steel plate 12 is not made.
[34] As described above, since a plurality of the corrugated steel plates 12 can be stacked without a wide space, transportation thereof can be made easily. Further, a stack- volume of the corrugated steel plate 12 can be decreased as compared with the prior art and thus a large quantity of the corrugated steel plates 12 can be transported in a limited space.
[35] Meanwhile, a stacked-corrugated steel plate 12 is transported to a construction site and then is used for construction work. As shown in FIG. 4, a bolt 50 is fastened respectively to a nut 21 that is welded to a corrugated steel plate 12 for use in construction work. Here, after fastening the bolt 50 to the nut 21, they are kept to be perpendicular to each other. Subsequently, in a state that the bolt 50 is fastened to the corrugated steel plate 12, the concrete 14 is poured to the outside of the corrugated steel plate 12 as shown in FIG. 5. After a predetermined period of time elapses, the concrete 14 is bonded securely to the bolt 50, and thus the reinforcing structure 10 that is constituted of the concrete 14 and corrugate steel plate 12 is fabricated securely.
[36] FIG. 5 is a cross sectional view showing a corrugated steel plate and a reinforcing structure thereof according to a second preferred embodiment of the present invention, wherein the configuration of a reinforcing structure is the same as the first embodiment except that the connection means is a thread hole 31 that is formed in the corrugated steel plate 12.
[37] As shown in FIG. 5, any structures are connected to the corrugated steel plate 12
and thus a deformation thereon is not made in stacking, thereby making storing and transport of a large quantity of the reinforcing structure efficient.
[38] In addition, the bolt 50 that is fastened to the thread hole 31 formed in the corrugated steel plate 12 may be connected to the nuts 51 of the other side of the corrugated steel plate 12. As a result, the bolt 50 can be fastened securely to the corrugated plate 12.
[39] FIG. 6 is a cross sectional view showing a corrugated steel plate and a reinforcing structure thereof according to a third preferred embodiment of the present invention, wherein a configuration of a reinforcing structure is the same as the first embodiment except that a connection means is a fitting hole that is formed in the corrugated steel plate 12.
[40] As shown in FIG. 6, the fitting hole 41 is tapered from one side of the corrugated steel plate 12 to the other side thereof such that the bolt 50 is fitted forcibly through the fitting hole 41 from one side of the corrugated steel plate 12 to the other side thereof.
[41] In addition, a jaw may be formed on an end of the bolt 50 to prevent the bolt 50 from being departed from the fitting hole 41.
[42] In fabricating the reinforcing structure as described above to the corrugated steel plate 12, the bolt 50 can be fitted into the fitting hole 41 with strikes by a tool such as a hammer, etc.
[43] As described above, the corrugated steel plate 12 includes a connection means such as a nut 21, a thread hole 31, a fitting hole 41 and a bolt 50 can be fastened directly to the connection means at a construction site, and therefore the stacking and storing of the corrugated steel plate 12 can be made easily.
[44] It will be apparent to those skilled in the art that various modifications and variations can be made to the structure for reinforcing a corrugated steel plate of the present invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided that they come within the scope of the appended claims and their equivalents.
