The present invention is in the form of a lattice reinforcement assembly (Lattice Reinforcement) and a corrugated plate (Steel Plate) composed of a steel plate of a bent cross-section. More specifically, a lattice reinforcing bar assembly and a corrugated plate made of a steel plate having a curved cross section are integrally combined to construct a composite deck, and the phase current is moved in the transverse direction by being engaged with a phase string constituting a lattice reinforcement bar assembly. By limiting the lateral buckling preventing clip member to the upper chord, it is possible to effectively suppress the occurrence of buckling in the transverse direction of the upper chord and the entire lattice reinforcing bar assembly when the bending load is applied, and furthermore A state in which the lattice rebar assembly and the corrugated plate are matched with the upward cambers provided to each by simply fixing the floor coupling spacer to be supported on the corrugated plate in advance, and to be easily fastened in the field with the lower chord. When the slab is constructed using a synthetic deck in the field by being able to be combined with, the lattice reinforcing bar assembly-synthetic deck of the corrugated plate with the lateral buckling prevention clip member enables the slab to be constructed in a designed linear manner, and The production method".

In constructing a building such as a building, a “composite deck” having a configuration in which a reinforcing bar assembly is placed on a plate of steel is installed, and concrete is formed in a predetermined thickness on the synthetic deck so that the reinforcing bar assembly is embedded in concrete. A method of constructing a slab by pouring has been proposed. As an example of such a prior art, Korean Patent Application Publication No. 10-2016-0145261 discloses a composite deck having a structure in which a reinforcing portion is disposed in a recessed portion, that is, a concave portion, in a curved steel plate. When viewed in the longitudinal direction, the steel plate has a curved shape in which concave portions are formed, and a plurality of concave portions are formed at a distance in the transverse direction, and an intermediate portion having a flat surface exists between adjacent concave portions. The concave portion and the intermediate portion are elongated throughout the entire steel plate in the longitudinal direction. For convenience, in this specification, a steel plate formed with such a concave portion and a flat intermediate portion is referred to as a "waveform plate".

The reinforcing bar assembly used for the production of the composite deck is composed of a plurality of longitudinal reinforcing bars extending in the longitudinal direction and arranged side by side, and a grid member connecting the longitudinal reinforcing bars in a grid. For convenience, in this specification, the reinforcing bar assembly used for manufacturing such a synthetic deck is referred to as a “lattice reinforcing bar assembly”. In the case of the reinforcing bar assembly disclosed in Korean Patent Publication No. 10-2016-0145261, it has two upper chords, one lower chord, and a lattice member, so that the reinforcing bar assembly has a long extended direction, that is, a cross-section viewed in the longitudinal direction. Although it has the shape of an inverted triangle, on the contrary, the cross section viewed in the longitudinal direction may have the shape of an equilateral triangle because there is one upper chord and two lower chords. At this time, if necessary, vertically overlapping a plurality of upper chords may be arranged to make the overall longitudinal cross-sectional shape to form an equilateral triangle, and furthermore, the upper and lower chords may be provided in a plurality of two or more. Particularly, when the upper and lower strings are provided in plural, the lateral spacing between the plurality of lower strings is larger than the horizontal spacing between the plurality of upper strings, and when viewed in the longitudinal direction, the upper and lower strings are trapezoidal. It may be deployed.

As mentioned above, with all of the lower chords of the lattice reinforcing bar assembly and part of the lattice member located within the recesses of the corrugated plate, the composite deck is produced by pouring concrete into the recesses and above the upper surface of the steel plate to a predetermined thickness. . When a load is applied to the composite deck, a large bending load is applied to the lattice reinforcing bar assembly. At this time, a "lateral buckling" phenomenon in which the phase current of the lattice reinforcing bar assembly is bent in the lateral direction may occur. The lateral buckling phenomenon that occurs in the phase current of the lattice reinforcing bar assembly is a cause of weakening the structural performance of the composite deck.

In the present invention, since the lateral movement of the phase current provided in the lattice reinforcing bar assembly and the curvature in the lateral direction of the phase current accordingly are strongly suppressed by the lateral buckling prevention clip member, the lattice reinforcing bar assembly is applied by the action of an external load. Even when the bending load is applied, it is possible to very effectively prevent the occurrence of lateral buckling in the entire phase and lattice reinforcing bar assembly. Therefore, the synthetic deck according to the present invention and the slab using the same have the advantage of stably exerting the designed structural performance.

As a member to limit the thing, as shown in the drawing, the fastening portion 30 is fastened with the upper chord 11, and extends obliquely on both sides of the fastening portion 30 so that the end is placed on the corrugated plate (2) It is configured to include a leg portion 32. In the case of the embodiment shown in Figures 6 to 8, the fastening portion 30 is formed with a fitting arrangement groove 31 in a concave and recessed shape from top to bottom, so that the upper chord 11 is fitted from the top to the bottom. It is positioned to be fitted in (31), and accordingly, a form in which the fastening part 30 supports the upper chord 11 from the bottom is fastened, and the upper chord 11 cannot be moved in the transverse direction, that is, transverse Directional movement is in a restricted state.

Leg portions 32 made of elongated members are integrally provided on both sides of the fastening portion 30 in the lateral direction. When the lattice reinforcing bar assembly 1 is placed in the concave portion 20 of the corrugated plate 2, the upper chord 11 should be located at a higher position than the middle portion 21 of the corrugated plate 2, To this end, the leg parts 32 may be arranged to be inclined downward. The outer end of the leg portion 32, that is, the end opposite to the portion engaged with the fastening portion 30 is placed on the corrugated plate 2, and if necessary, integrally assembled to the corrugated plate 2 In order to be able to, the coupling plate 320 may be provided at the outer end of the leg portion 32. By combining the coupling plate 320 with the corrugated plate 2 using a fixing material 321 such as a through bolt, the lateral buckling preventing clip member 3 can be fixed to the corrugated plate 2.

The lateral buckling prevention clip member 3 may be installed in a state in which the lower portion of the lattice reinforcing bar assembly 1 is inserted and disposed in the concave portion 20. 9 is a schematic lateral perspective view sequentially showing an example of a process of installing a lateral buckling prevention clip member 3 in a state where the lower chord 12 of the lattice reinforcing bar assembly 1 is located in the recess 20 It is shown. First, as shown by the dotted line (A) in FIG. 9, the lateral buckling prevention clip member 3 is tilted to be inserted below the top chord 11. Subsequently, the lateral buckling prevention clip member 3 is raised in the direction indicated by the arrow ⓐ in FIG. 9 so that the fastening portion 30 of the lateral buckling prevention clip member 3 that is inclined faces the longitudinal direction. ), the ends of both leg portions 32 of the lateral buckling prevention clip member 3 begin to adhere to the corrugated plate 2 in this process. Subsequently, when the lateral buckling prevention clip member 3 is rotated in the direction of the arrow ⓑ to be positioned so that the fastening portion 30 is orthogonal to the longitudinal direction, the upper chord 11 of the lattice reinforcing bar assembly 1 is a fastening portion ( 30) is inserted into the fitting arrangement groove 31, both ends of the leg portion 32 of the lateral buckling prevention clip member 3 is in close contact with the corrugated plate 2, the lateral buckling prevention clip member 3 is shown in FIG. It is installed at a position orthogonal to the longitudinal direction in the form shown by a solid line. The above description with respect to FIG. 9 is only an example of a method of coupling and installing the lateral buckling prevention clip member 3 to the lattice reinforcing bar assembly 1, but is not limited thereto.

In the present invention, the lateral buckling prevention clip member 3 may be provided with a plurality of spaced apart spaces over the entire length of the lattice reinforcing bar assembly 1 in the longitudinal direction, and when the floor coupling spacer 4 described above is provided, It may be provided in the same position as the bottom coupling spacer (4). Of course, in some cases, as described above, the lateral buckling prevention clip member 3 is not installed in the state where the lower chord 12 of the lattice reinforcing bar assembly 1 is located in the recess 20, but the lateral buckling prevention clip The fastening part 30 of the member 3 and the upper chord 11 are fastened by a method such as binding with a binding line, so that the lateral buckling prevention clip member 3 is previously coupled to the lattice reinforcing bar assembly 1 In, the lower portion of the lattice reinforcing bar assembly 1 may be disposed in the recess 20 so that the end of the leg portion 32 of the lateral buckling prevention clip member 3 is in close contact with the corrugated plate 2.

In the state in which the lateral buckling prevention clip member 3 is installed according to the present invention, the lateral buckling prevention clip member 3 is positioned while traversing over the concave portion 20 of the corrugated plate 2 in the transverse direction, and Since the legs 32 extended to be inclined on both sides of the direction are supported, and the upper chord 11 of the lattice reinforcing bar assembly 1 is located in the fitting arrangement groove 31 of the lateral buckling prevention clip member 3 , The lateral movement of the top chord 11 is in a very strongly inhibited state.

After the lattice reinforcing bar assembly 1 is installed on the corrugated plate 2 and the synthetic deck is produced, the concrete 210 is installed on the inside of the concave portion 20 and the upper surface of the corrugated plate 2 with the synthetic deck installed on site. When is poured to a predetermined thickness, a slab 200 in the form of a lattice reinforcing bar assembly 1 embedded in concrete is manufactured. 10 is a schematic perspective view showing a state in which the concrete 210 is poured into the composite deck 100 of the present invention to complete the slab 200. In this way, in the slab constructed using the composite deck of the present invention, the lateral movement of the upper chord 11 and the curvature in the lateral direction of the upper chord 11 are strongly suppressed by the transverse buckling prevention clip member 3. Therefore, even if a bending load is applied to the lattice reinforcing bar assembly by the action of an external load, it is possible to very effectively prevent the lateral buckling from occurring in the upper chord 11 and the entire lattice reinforcing bar assembly. Therefore, the slab using the synthetic deck according to the present invention stably exhibits the designed structural performance.

Particularly, in the present invention, the lateral buckling prevention clip member 3 has a very simple structure, and can be installed very easily and very quickly in the field, so it has high utilization in the field and can be used very efficiently. .

On the other hand, as mentioned above, the lateral buckling prevention clip member 3 according to the present invention may be provided with a coupling plate 320 at the outer end of the leg portion 32, and the lateral buckling prevention clip member 3 as above. When placed across the concave portion 20 of the corrugated plate 2, the coupling plate 320 can be fixed by the corrugated plate 2 using a fixing material 321 such as a through bolt. That is, in the state in which the coupling plate 320 is placed on the corrugated plate 2, the fixing plate 321 such as a through bolt is penetrated through the coupling plate 320 and the corrugated plate 2 so that the coupling plate 320 does not move. , It can be fixed to the lateral buckling clip member (3) to the corrugated plate (2). Of course, the bonding plate 320 may be fixed to the corrugated plate 2 by other methods such as welding or adhesion.

In the present invention, the coupling plate 320 does not need to be composed only of a flat plate member as shown in FIG. 8, and may be configured in the form of a bending plate according to the position where the coupling plate 320 is placed on the corrugated plate 2. have. 11 is a schematic perspective view of a lateral buckling preventing clip member 3 according to another embodiment of the present invention in which the coupling plate 320 is formed in a bent plate shape. When the coupling plate 320 is made of a bending plate as shown in FIG. 11, the coupling plate 320 of the leg portion 32 can be easily placed on the corner portion of the corrugated plate 2.

In addition, in forming the fitting arrangement groove 31 to be fastened with the upper chord 11 in the present invention in the fastening portion 30 of the lateral buckling prevention clip member 3, as shown in FIGS. 6 to 10, from top to bottom Although the fitting placement groove 31 may be formed in a concave fine shape, on the contrary, the fitting placement groove 31 may be formed in a concave fine shape from bottom to top. 12 is a schematic perspective view of a lateral buckling prevention clip member 3 according to another embodiment of the present invention in which the fitting arrangement groove 31 in the fastening portion 30 is made in a concavely recessed form from bottom to top. FIG. 13 is a schematic longitudinal front view corresponding to FIG. 7 showing that the lateral buckling clip member 3 shown in FIG. 12 is coupled to the lattice reinforcing bar assembly 1.

In the present invention, the fitting arrangement groove 31 formed in the fastening portion 30 of the lateral buckling prevention clip member 3 may be deformed into a hole shape. 14 is a schematic perspective view of a transverse buckling prevention clip member 3 according to another embodiment in which the fitting arrangement groove 31 of the fastening portion 30 is made into a hole shape, and FIG. 15 is illustrated in FIG. 14. A schematic longitudinal frontal view corresponding to FIG. 7 is shown showing that the illustrated lateral buckling clip member 3 is coupled to the lattice reinforcement rebar assembly 1. 14 and 15, the fitting arrangement groove 31 may be made into a hole shape with an opening formed on the side surface. In this case, the upper chord 11 is formed through a hole-shaped fitting arrangement groove through the opening formed on the side surface. It is inserted into (31) and positioned.

12 and 13, the fitting arrangement groove 31 is made in a concavely recessed form from the bottom to the top, and the upper and lower sides are wrapped by the fastening portion 30 so that the upper side 11 is wrapped in the transverse direction. Although the movement is limited, in the case of the embodiment shown in FIGS. 6 to 11 and the embodiment shown in FIGS. 14 to 15, the upper chord 11 is disposed in the fitting arrangement groove 31 and the upper chord 11 ), and at the same time, the fastening portion 30 supports the lower portion of the upper chord 11. Therefore, in this configuration, by inserting the upper chord 11 into the fitting arrangement groove 31, the lattice reinforcing bar assembly 1 is combined with the lateral buckling prevention clip member 3 to become a hanging form. When the fastening part 30 is used with the bottom coupling spacer 4 described above, the lateral buckling prevention clip member 3 in the form of supporting the lower part of the upper chord 11, the upward of the corrugated plate 2 It will be possible to exert an additional advantageous effect of adjusting the camber to fit the upward camber of the lattice rebar assembly 1.

In general, it is preferable to lengthen the longitudinal span of the composite deck for space utilization of the building, etc., and for this purpose, the longitudinal section of the lattice reinforcing bar assembly (1) goes upward in the longitudinal direction so that it rises upward and gently A convex upward camber is provided to the lattice reinforcing bar assembly 1. An upward camber may also be provided to the corrugated plate 2, but due to an error in manufacturing and processing, an error in transportation and storage, and the like, an upward camber provided to the lattice reinforcing bar assembly 1 and the corrugated plate 2 It is very difficult for the given upward camber to be completely matched. While the lattice rebar assembly 1 has a large flexural stiffness, the corrugated plate 2 has a relatively small flexural stiffness than the lattice reinforcement rebar assembly 1, so the upward camber originally applied in the process of transportation, storage, etc. It is also reduced, and when the lattice reinforcement assembly 1 is installed on the corrugated plate 2, the lattice reinforcement assembly 1 and the corrugated plate 2 show a significant difference in camber. In the case of constructing a composite deck by pouring concrete, although there is an upward camber difference between the lattice reinforcing bar assembly 1 and the corrugated plate 2, the lattice reinforcing bar assembly 1 and the corrugated plate 2 due to the difference in camber ) Intervals may be irregular and irregular. Therefore, in order to prevent such a problem, it is desirable to make the camber coincide with the upward camber of the lattice rebar assembly and the upward camber of the corrugated plate.

In the present invention, the bottom coupling spacer 4 of the above-described configuration may be provided as required. In this case, in the state where the lower chord 12 of the lattice rebar assembly 1 is fastened to the bottom coupling spacer 4, the lateral buckling prevention clip member 3 is disposed and the top of the lattice rebar assembly 1 Positioning the current (11) in the fitting arrangement groove (31) of the lateral buckling prevention clip member (3), such as the embodiment shown in Figures 6 to 11 and the embodiment shown in Figures 14 to 15, the fastening section (30) When supporting the lower portion of the virtual chord 11, the lattice rebar assembly 1 is positioned hanging from the lateral buckling clip 3, while the lower chord 12 of the lattice rebar assembly 1 is a bottom coupling spacer. It is integrated with the corrugated plate 2 through (4). In this process, the corrugated plate 2 is pulled toward the lattice reinforcing bar assembly 1. Since the lattice rebar assembly 1 has a greater rigidity than the corrugated plate 2, the upward camber of the corrugated plate 2 is fitted to the upward camber of the lattice reinforcement rebar assembly 1.

In the state in which the upward camber of the lattice reinforcing bar assembly 1 and the upward camber of the corrugated plate 2 are different, the upward camber of the corrugated plate 2 is in the process of installing the lateral buckling prevention clip member 3 in the manner described above. Adjusted to fit the upward camber of the lattice rebar assembly 1, the effect that the corrugated plate 2 and the lattice rebar assembly 1 have the same upward camber is exhibited. When such an upward camber is made, when concrete is poured onto the upper surface of the corrugated plate 2 after the completed synthetic deck of the present invention is installed in the field, when the slab is constructed, the lower surface of the slab becomes convex downward or uneven. It has the advantage of not being in a shape and being able to stably maintain the shape and linearity originally designed.
