The present disclosure relates to a deck panel for construction including a coupling member for coupling the deck panels.
Recently, reinforced concrete structures are most widely used for construction process methods because the reinforced concrete structure has excellent rigidity, durability, fire resistance, earthquake resistance, and soundproof performance.
In the case of a mold process method in the related art, which is used to construct a building with the reinforced concrete structure, a process is complicated, it is difficult to dismantle arranged bars and molds, and a large number of wastes are produced, and as a result, recently, a process method using a deck panel is used to construct floor or ceiling slabs.
Here, the deck panel broadly includes a deck plate and a truss girder.
The deck plate serves as not only a mold, but also a surface of a concrete structure after construction, and the deck plate may be made of a galvanized steel plate in order to prevent corrosion caused by the concrete. The plurality of deck plates is connected to form a floor surface or a ceiling surface of a building.
The truss girder includes a lattice unit which has a predetermined corrugated shape, and a fixing unit which securely fixes the lattice unit, and the lattice unit and the fixing unit are formed as steel reinforcements and may be fastened onto the deck plate.
The deck panel is manufactured at a predetermined place, transported to a construction site, and then disposed on a floor or a ceiling of a building, and then concrete is poured and cured for a predetermined period of time, such that a structure of the building is constructed.
However, the deck panel in the related art has a problem in that a use of the deck panel is limited only to floor or ceiling slabs of a building, and has a drawback in that an overall period for construction of a building is long.
In addition, because the deck plate and the truss girder are fastened and assembled by welding, the time required to assemble the deck plate and the truss girder is somewhat long, and an assembly tolerance may be incurred.
In addition, a construction method using the deck panel in the related art involves an in-situ process of arranging bars in order to connect the respective deck panels. Therefore, there is a problem in that an overall construction period is increased due to a process of welding at a construction site or a separate reinforcement process of arranging bars, which causes an increase in personnel expenses and material costs and affects quality of construction in accordance with skill of in-situ technicians.
The present disclosure has been made in an effort to solve the aforementioned problems, and an object of the present disclosure is to provide an environmentally-friendly deck panel for construction, in which a structure of the deck panel is improved and modularized, thereby reducing a period for construction of a reinforced concrete building, reducing construction costs, improving stability and construction quality, and minimizing construction wastes.
In addition, another object of the present disclosure is to provide a deck panel for construction which implements a deck panel structure in which the deck panels, which are disposed on a partitioned building, may be coupled, such that construction of a high-rise building may be simply and quickly performed.

In addition, each of the lateral side truss girder of the two lateral side deck panel includes a pair of lattices which is formed in a predetermined corrugated shape; an upper chord member which is coupled to upper pitches of the pair of lattices and fixes upper portions of the pair of lattices; and a pair of lower chord members which is disposed in parallel with each other at a lower side of the pair of lattices
In addition, the coupling member includes plurality of hook members disposed at an equal interval the upper chord members to seat on the other side of the lateral side deck panel.
In addition, each of the lateral side deck panel further includes a lateral side reinforcement part which is coupled to the lateral side deck plate or the lateral side truss girder.
In addition, the lateral side reinforcement part includes a fifth lateral side reinforcement member which is coupled to the free end of the lateral side fastening portion and has both ends coupled to the pair of lower chord members; a second lateral side reinforcement member which is coupled to the upper chord member, the free end of the lateral side fastening portion, and the fifth lateral side reinforcement member; a plurality of first lateral side reinforcement member which has one end coupled to an inner side at one end of any one pair of lattices among the multiple pairs of lattices, and the other end coupled to an inner side at the other end of another pair of lattices; and a pair of third lateral side reinforcement members which is coupled to inner sides of the lateral side deck plate and lower surfaces of the pair of lower chord members, is disposed perpendicular to the pair of lower chord members.
In addition, the hook member is seated on the third lateral side reinforcement member disposed on the lateral side deck panel.
The present disclosure may provide the deck panel having excellent structural rigidity which may be disposed not only at an upper side of the partitioned building, but also at a lateral side of the partitioned building.
In addition, the present disclosure may provide the deck panel capable of reducing a construction period, and reducing the amount of construction wastes.

A central portion of the fifth upper side reinforcement member 135 may be coupled to the free end of the upper side fastening portion 122a, and both ends of the fifth upper side reinforcement member 135 may be coupled to the pair of lower chord members 123, respectively.
That is, the deck panel 100 of the present disclosure, which includes the upper side reinforcement part 130 according to the exemplary embodiment of the present disclosure, may reduce a vacant space between the truss girders 120, implement excellent durability of a building in comparison with the related art, reduce the amount of concrete to be poured, reduce construction costs and a concrete curing period, and consequently reduce construction costs.
Here, the lattice 121, the upper chord member 122, or the lower chord member 123 may be elongated in parallel with a long side of the upper side deck plate 110.
In addition, the third upper side reinforcement member 133, the fourth upper side reinforcement member 134, or the fifth upper side reinforcement member 135 may be formed in parallel with a short side of the upper side deck plate 110.
In addition, the constituent elements may be coupled by means of welding or separate coupling members, but may be coupled by the electric pressure welding method.
Hereinafter, the lateral side deck panel according to the exemplary embodiment of the present disclosure will be described.
A lateral side deck panel 200 according to the exemplary embodiment of the present disclosure broadly includes a lateral side deck plate 210, lateral side truss girders 220, and lateral side reinforcement parts 230.
In addition, the lateral side deck plate 210 may be formed as a galvanized steel plate or a metallic plate, which is plated with zinc, in order to prevent corrosion caused by concrete which is poured after the upper side deck plate 110 is disposed on a building.
The lateral side truss girder 220 may include a pair of lattices 221, upper chord members 222, or lower chord members 223.
Specifically, two or more pairs of lattices 221 may be disposed in parallel on the lateral side deck plate 210, and as illustrated, a total of two pairs of lattices 221 may be disposed on the single lateral side deck plate 210.
Meanwhile, the lateral side truss girder 220 may include the upper chord member 222 which is coupled to upper pitches of the pair of lattices 221 and fixes upper portions of the pair of lattices 221.
The upper chord member 222 is a steel reinforcement having a long straight shape, and may be coupled between the upper pitches of the pair of lattices 221, and the coupling method may be implemented by an electric pressure welding method.
In addition, the upper chord member 222 may further include a lateral side fastening portion 222a which protrudes to the outside of the lateral side deck plate 210 and is formed in a ⊏ shape, such that a free end of the lateral side fastening portion 222a is formed to be disposed to be spaced apart from an upper side of the lateral side deck plate 210.

Meanwhile, the lateral side truss girder 220 may include the pair of lower chord members 223 which are disposed at lower sides of the pair of lattices 221, respectively, and disposed in parallel so as to be spaced apart from the lateral side deck plate 210 at a predetermined interval.
Therefore, first lateral side reinforcement members 231 and third lateral side reinforcement members 233, which will be described below, may be disposed between the lower chord members 223 spaced apart from the lateral side deck plate 210, and this structural feature may further improve mechanical strength of the lateral side deck panel 200 of the present disclosure.
In addition, each of the lower chord members 223 is a steel reinforcement having a long straight shape, and the lower chord members 223 may be coupled to lower pitches of the pair of lattices 221, respectively, and the coupling method may be implemented by the electric pressure welding method.
Meanwhile, the construction method in the related art does not use a process of pouring concrete by using the deck panel at a lateral side of a building. The reason is that a load of the poured concrete is more greatly applied to the lateral side than the upper side, and thus the deck panel of the related art does not permit the load of the concrete.
However, because the lateral side deck panel 200 of the present disclosure has excellent mechanical strength, the lateral side deck panel 200 may also be applied to a lateral side of a building, which may reduce a construction period and efficiently ensure an internal space.
In addition, since the lateral side deck panel 200 may be implemented, the partitioned buildings, which have the upper side deck panel 100 and the lateral side deck panel 200 disposed thereon, may be significantly easily coupled, such that a construction period is greatly reduced, and therefore, construction costs may be reduced, and a rigid lateral side may be formed.
Specifically, the lateral side reinforcement part 230 is coupled to the lateral side deck plate 210 and/or the lateral side truss girder 220, thereby improving strength of the deck panel 200, and the lateral side reinforcement part 230 may include the first lateral side reinforcement members 231, second lateral side reinforcement members 232, the third lateral side reinforcement members 233, fourth lateral side reinforcement members 234, or fifth lateral side reinforcement members 235.

That is, straight shapes of one end and the other end of the first lateral side reinforcement member 231 may be coupled to the two pairs of lattices 221 disposed at outermost sides of the single lateral side deck plate 210, and an intermediate portion of the first lateral side reinforcement member 231 may be formed to have a diagonal shape that connects one end and the other end of the first lateral side reinforcement member 231.
In addition, the first lateral side reinforcement member 231 may be disposed, one for each pitch of a corrugated shape of the lattice 221, and the plurality of first lateral side reinforcement members 231 may be disposed to correspond to the adjacent first lateral side reinforcement member 231 or in the same direction.
The second lateral side reinforcement member 232 may be coupled to the upper chord member 222, the free end of the lateral side fastening portion 222a, and the fifth lateral side reinforcement member 235 to be described below, and the second lateral side reinforcement member 232 may be formed in a shape which is bent twice approximately at a right angle.
In addition, the third lateral side reinforcement member 233 may be disposed as a pair of third lateral side reinforcement members 233 which is coupled to inner sides of the pair of lattices 221 and lower surfaces of the pair of lower chord members 223, and disposed perpendicular to the pair of lower chord members 223.
The third lateral side reinforcement members 233 may be disposed at an equal interval on the upper side deck plate 210 which is disposed at an entire upper side of a building, or the third lateral side reinforcement members 233 may be disposed only at an edge of the upper side deck plate 210, but in consideration of a load of concrete, the plurality of third lateral side reinforcement members 233 may be disposed at an equal interval as illustrated.
In addition, the third lateral side reinforcement member 233 may include a ⊏-shaped first coupling portion 233a outside the lateral side deck plate 210. The first coupling portion 233a crosses a second coupling portion 234a of the fourth lateral side reinforcement member 234 to be described below at a side adjacent to the first coupling portion 233a, thereby improving mechanical strength of the deck panel 200.
The fourth lateral side reinforcement members 234 may be disposed as a pair of fourth lateral side reinforcement members 234 disposed in parallel with each other, in which one fourth lateral side reinforcement member 234 is perpendicularly coupled to an upper side of the upper chord member 222, and the other fourth lateral side reinforcement member 234 is perpendicularly coupled to the pair of lower chord members 223.
In addition, the fourth lateral side reinforcement member 234 may include a ⊏-shaped second coupling portion 234a outside the lateral side deck plate 210. The second coupling portion 234a crosses the first coupling portion 233a at a side adjacent to the second coupling portion 234a or crosses the second coupling portion 234a at a side adjacent to the second coupling portion 234a, thereby improving mechanical strength of the deck panel 200.
Meanwhile, referring to
In addition, auxiliary reinforcement members 233b and 234b having a truss structure may be disposed between the pair of third lateral side reinforcement members 233 or the pair of fourth lateral side reinforcement members 234 in order to improve mechanical strength.
The fifth lateral side reinforcement member 235 may be coupled to the free end of the lateral side fastening portion 222a, and both ends of the fifth lateral side reinforcement member 235 may be coupled to the pair of lower chord members 223, respectively.
That is, the lateral side deck panel 200 of the present disclosure, which includes the lateral side reinforcement part 230 according to the exemplary embodiment of the present disclosure, may reduce a vacant space between the truss girders 220, implement excellent durability of a building in comparison with the related art, reduce the amount of concrete to be poured, reduce construction costs and a concrete curing period, and consequently reduce construction costs.
Here, the lattice 221, the upper chord member 222, or the lower chord member 223 may be elongated in parallel with a long side of the lateral side deck plate 210.
In addition, the third lateral side reinforcement member 233, the fourth lateral side reinforcement member 234, or the fifth lateral side reinforcement member 235 may be formed in parallel with a short side of the lateral side deck plate 210.
In addition, the constituent elements may be coupled by means of welding or separate coupling members, but may be coupled by the electric pressure welding method.
As illustrated in
As described above, the disposition on the sidewall may improve strength of the sidewall, may significantly reduce a construction period and construction costs because no mold is required, and may make it easy to couple the respective partitioned buildings.
Therefore, the present disclosure may include coupling members 300 in order to couple or fix the upper side deck panels 100 and/or the lateral side deck panels 200.
The coupling members 300 broadly include hook members 340, a horizontal coupling member 310, a vertical coupling member 320, or an auxiliary horizontal coupling member 330.

Referring to
The hook member 340 may be seated on the third lateral side reinforcement member 233 disposed on the lateral side deck panel 200 of another partitioned building, and as a result, the partitioned buildings may be disposed at a constant interval, and it is possible to provide force that withstands a load when concrete is poured between the two facing lateral side deck panels 200.
In addition, as illustrated, the hook members 340 are disposed on one lateral side deck panel 200 at an equal interval so as to be opened upward, and the hook members 340 may be disposed on the other lateral side deck panel 200 at an equal interval so as to be opened downward.
That is, the hook members 340 may be provided to couple the partitioned buildings, or maintain an interval with the other lateral side deck panel 200 for forming the sidewall, and increase strength.
Referring to
The horizontal coupling member 310 may be disposed to securely support respective sides of the single partitioned building or securely and constantly maintain connection between the partitioned buildings. Specifically, referring to
To form a rigid structure, the horizontal coupling member 310 may be formed in a rectangular shape, and may be disposed to correspond to a quadrangular space formed by the upper side fastening portion 122a and the lateral side fastening portion 222a or the vertical coupling member 320.
Therefore, the horizontal coupling member 310 may include four bars 311 which define respective sides of a rectangular shape, and connecting portions 312a and 312b which connect the adjacent bars, and in consideration of a stress concentration direction caused by the partitioned building or a load of concrete, the connecting portions 312b may be formed in a corrugated shape having a predetermined pitch with respect to the facing surfaces perpendicular to the ground surface as illustrated.
Referring to
The vertical coupling member 320 may be disposed to securely support respective sides of the single partitioned building or securely and constantly maintain a connection between the partitioned buildings. Specifically, the vertical coupling member 320 may be disposed in a space formed as the first coupling portions 234a of the adjacent partitioned buildings cross each other or a space formed as the first coupling portion 233a and the first coupling portion 234a cross each other on the same partitioned building.

Therefore, the vertical coupling member 320 may include four bars 321 which define respective sides of the rectangular shape, and connecting portions 321a and 321b which connect the bars, and in consideration of a stress concentration direction caused by the partitioned building or a load of concrete, the connecting portions 321b may be formed in a corrugated shape having a predetermined pitch with respect to at least one facing surface perpendicular to the ground surface as illustrated.
In addition, in the present disclosure, the vertical coupling member 320 may include the extension portion 323 which is formed in a ⊏ shape and has a free end that connects the two adjacent bars in order to implement the technical spirit in which the partitioned building may be coupled at the top side.
In addition, a pair of extension portions 323 may be formed at an end of the vertical coupling member 320 so as to face each other.
The extension portion 323 enables a lower end of another vertical coupling member 320 provided on the partitioned building disposed at the top side to be securely and stably disposed.
Therefore, a distance between facing surfaces of the pair of extension portions 323 may be longer than a distance between the facing bars.
Referring to
The auxiliary horizontal coupling member 330 may be disposed to securely and constantly maintain connection between the partitioned buildings in a case in which a separate partitioned building is additionally constructed at an upper side of the partitioned building. Specifically, the auxiliary horizontal coupling member 330 may be disposed in a space formed as the vertical coupling members 320, which are disposed on the same line on the partitioned buildings adjacent in an up and down direction, cross each other.
The auxiliary horizontal coupling member 330 may include four bars 331 which define respective sides of the rectangular shape, and connecting portions 332a and 332b which connect the bars, and in consideration of a stress concentration direction caused by the partitioned building or a load of concrete, the connecting portion 332b, which is perpendicular to the ground surface, may be formed in a corrugated shape having a predetermined pitch as illustrated.
In summary, the present disclosure may provide the deck panels 100 and 200 including the coupling member 300 in order to reinforce strength of an edge of the single partitioned building or constantly, stably, and securely couple the respective partitioned buildings.
From the foregoing, it can be understood by those skilled in the art that the present disclosure may be variously changed and modified without departing from the technical spirit of the present disclosure, and the technical scope of the present disclosure is not limited by the contents described in the exemplary embodiment, but should be determined by the claims and the equivalents thereto.
