"Lattice reinforcement reinforcement assembly with clip member to prevent lateral buckling, which allows the slab to be constructed in a designed linear shape when the slab is constructed using a synthetic deck on site-a composite deck of corrugated plate and It is related to the production method".

In constructing buildings such as buildings, a "composite deck" consisting of a reinforcing bar assembly arranged on a plate of steel is installed, and concrete at a predetermined thickness is placed on the composite deck so that the reinforcing bar assembly is embedded in the concrete. A method of constructing a slab by pouring has been proposed. As an example of such a prior art, Korean Patent Laid-Open Publication No. 10-2016-0145261 discloses a composite deck having a configuration in which a reinforcing bar assembly is arranged in a concave 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. The concave portions are formed with a plurality of spaces apart in the transverse direction, and there is an intermediate portion made of a flat surface between adjacent concave portions. The concave portion and the intermediate portion are formed to be elongated over the entire steel plate in the longitudinal direction. For convenience, in this specification, a steel plate in which such a concave portion and a flat intermediate portion are formed is referred to as a "corrugated plate".

The reinforcing bar assembly used in the manufacture of the composite deck consists of a plurality of longitudinal reinforcing bars that are elongated in the longitudinal direction and arranged side by side, and a grid member that connects the longitudinal reinforcing bars in a grid form. For convenience, in this specification, the reinforcing bar assembly used in the manufacture of such a composite deck is referred to as "lattice reinforcing bar assembly". In the case of the reinforcing bar assembly disclosed in Korean Laid-Open Patent Publication No. 10-2016-0145261, it has two upper chords, one lower chord, and a grid member, so that the reinforcing bar assembly is viewed in a longitudinal direction, that is, a cross section viewed in the longitudinal direction. Although it has the shape of an inverted triangle, on the contrary, there is one upper chord and two lower chords, so the cross section viewed in the longitudinal direction may have the shape of an equilateral triangle. At this time, if necessary, a plurality of upper chords may be vertically overlapped so that the overall longitudinal cross-sectional shape may form an equilateral triangle, and further, two or more upper chords may be provided. In particular, when a plurality of upper and lower chords are provided, the lateral spacing between the plurality of lower chords is larger than the lateral spacing between the plurality of upper chords, and when viewed in the vertical direction, the upper chord and the lower chord are trapezoidal. It can also be placed.

As mentioned above, a composite deck is produced by pouring concrete to a predetermined thickness inside the recess and on the upper surface of the steel plate while all of the lower chords of the lattice rebar assembly and part of the grid member are located in the recess of the corrugated plate. . When a load is applied to such a composite deck, a large bending load is applied to the lattice reinforcing bar assembly, and at this time, a "lateral buckling" phenomenon may occur in which the upper chord of the lattice reinforcing bar assembly is bent in the transverse direction. The lateral buckling phenomenon occurring in the upper chord of the lattice reinforcing bar assembly is a cause of weakening the structural performance of the composite deck.

The middle part 21 may be formed of a flat surface.

3 is a schematic perspective view showing the installation of the bottom coupling spacer 4 in the concave portion 20 of the corrugated plate 2 according to the present invention, and FIG. 4 is a lattice reinforcement following the state of FIG.

In this way, according to the configuration in which the floor coupling spacer 4 is fixed to the corrugated plate 2 and the lattice reinforcing bar assembly 1 is assembled with the floor coupling spacer 4, the corrugated plate 2 and the lattice are described later. The advantage of being able to easily adjust the upward camber match between the reinforcing bar assemblies 1 is exhibited. However, in a state in which the floor coupling spacer 4 is previously joined to the lattice rebar assembly 1, the lower part of the lattice rebar assembly 1 is lifted and the lower part of the lattice rebar assembly 1 is recessed in the corrugated plate 2 The bottom coupling spacer 4 may be fixed to the bottom surface of the concave portion 20 after inserting and disposing it in (20).

In addition to the function of securing the reinforcing bar cover thickness required between the bottom chord 12 of the lattice reinforcing bar assembly 1 and the bottom surface of the recess 20, the floor coupling spacer 4 having the above configuration is very easy and accurate. As will be described later, a very important function can also be exhibited in matching the upward camber of the lattice reinforcing bar assembly 1 and the upward camber of the corrugated plate 2.

On the other hand, in the present invention, the lattice reinforcing reinforcing bar assembly (1) is coupled to the transverse buckling prevention clip member (3) to prevent lateral buckling of the upper chord (11). 6 is a schematic perspective view showing a state in which the lateral buckling prevention clip member 3 is installed in the lattice reinforcing bar assembly 1 following the state of FIGS. 4 and 5, and FIG. 7 is shown in FIG. A schematic longitudinal front view of the condition is shown. 8 is a schematic perspective view showing the lateral buckling prevention clip member 3 provided in the embodiment of the present invention shown in FIGS. 6 and 7.

The transverse buckling prevention clip member 3 is installed while crossing the concave portion 20 of the corrugated plate 2 in the transverse direction and is fastened with the upper chord 11 so that the upper chord 11 is displaced in the transverse direction. As a member for limiting this, as shown in the drawing, the fastening part 30 fastened to the upper chord 11 and the fastening part 30 are obliquely extended from both sides in the transverse direction 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 Figs. 6 to 8, the fastening portion 30 is formed with a fitting arrangement groove 31 in a shape that is concave from the top to the bottom, so that the upper chord 11 is a fitting arrangement groove from the top to the bottom. It is positioned by being inserted into (31), and accordingly, a form in which the fastening part 30 supports the top chord 11 from the bottom to the top is fastened, and the top chord 11 cannot be moved in the transverse direction, that is, the transverse Directional movement is limited.

Legs 32 made of elongated members are integrally provided on both sides of the fastening portion 30 in the transverse direction. When the lattice reinforcing bar assembly 1 is positioned in the concave portion 20 of the corrugated plate 2, the upper chord 11 must be present at a higher position than the middle portion 21 of the corrugated plate 2, To this end, the leg portions 32 may be disposed to be inclined downward, respectively. The outer end of the leg portion 32, that is, the end opposite to the portion coupled to the fastening portion 30, is placed on the corrugated plate 2, and if necessary, it may be integrally assembled and coupled to the corrugated plate 2 In order to be able to do so, a coupling plate 320 may be provided at an outer end of the leg portion 32. By coupling the coupling plate 320 by the corrugated plate 2 using a fixing member 321 such as a through bolt, the lateral buckling prevention 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 into the concave portion 20. 9 is a schematic lateral perspective view sequentially showing an example of a process of installing the lateral buckling prevention clip member 3 in a state in which the lower chord 12 of the lattice reinforcing bar assembly 1 is located in the recess 20 Is shown. First, as shown by the dotted line (A) in FIG. 9, the transverse buckling prevention clip member 3 is tilted so that it is inserted downward of the upper chord 11. The lateral buckling prevention clip member 3 is raised in the direction indicated by the arrow ⓐ in Fig. 9 so that the fastening part 30 of the lateral buckling prevention clip member 3 that has been inclined subsequently looks in the longitudinal direction, and the dotted line (B) in Fig. 9 ), and in this process, the ends of both legs 32 of the lateral buckling prevention clip member 3 begin to come into close contact with the corrugated plate 2. Subsequently, when the lateral buckling prevention clip member 3 is rotated in the direction of arrow ⓑ so that the fastening part 30 is positioned so as to be perpendicular to the longitudinal direction, the upper chord 11 of the lattice reinforcing bar assembly 1 is the fastening part ( 30) is inserted into the fitting arrangement groove 31, and the ends of both legs 32 of the lateral buckling prevention clip member 3 are in close contact with the corrugated plate 2, so that the lateral buckling prevention clip member 3 is shown in FIG. 9 It is installed in 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 transverse buckling prevention clip member 3 to the lattice reinforcing bar assembly 1 and is not limited thereto.

In the present invention, a plurality of lateral buckling prevention clip members 3 may be provided at intervals 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 at the same position as the bottom coupling spacer 4. Of course, in some cases, as described above, instead of installing the lateral buckling prevention clip member 3 while the lower chord 12 of the lattice reinforcing bar assembly 1 is located in the concave portion 20, the lateral buckling prevention clip A state in which the lateral buckling prevention clip member (3) is connected to the lattice reinforcing bar assembly (1) in advance by fastening the fastening part (30) of the member (3) and the upper chord (11) with a binding line. In, the lower portion of the lattice reinforcing bar assembly 1 may be disposed in the concave portion 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 crossing the concave portion 20 of the corrugated plate 2 in the transverse direction, Legs 32 extending to be inclined are supported on both sides of the direction, and the upper chord 11 of the lattice reinforcing bar assembly 1 is located within the fitting arrangement groove 31 of the lateral buckling prevention clip member 3 , The transverse movement of the upper chord 11 is very strongly suppressed.

After the lattice reinforcing bar assembly (1) is installed on the corrugated plate (2) to produce the composite deck, the concrete (210) on the inside of the recess (20) and the upper surface of the corrugated plate (2) while the composite deck is installed on site. When is poured to a predetermined thickness, the slab 200 in a form in which the lattice reinforcing bar assembly 1 is embedded in concrete is manufactured. 10 is a schematic perspective view showing a state in which the slab 200 is completed by pouring concrete 210 into the composite deck 100 of the present invention. In the slab constructed using the composite deck of the present invention as described above, the lateral movement of the upper chord 11 and the resulting warp in the transverse direction of the upper chord 11 are strongly suppressed by the lateral 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 occurrence of a lateral buckling phenomenon in the upper chord 11 and the entire lattice reinforcing bar assembly. Therefore, the slab using the composite deck according to the present invention stably exhibits the designed structural performance.

In particular, 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, and has the advantage that it is highly utilized 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 is provided as above. In arranging across the concave portion 20 of the corrugated plate 2, the coupling plate 320 may be fixed by the corrugated plate 2 using a fixing member 321 such as a through bolt. That is, in a state in which the coupling plate 320 is placed on the corrugated plate 2, a fixing member 321 such as a through bolt is passed through the coupling plate 320 and the corrugated plate 2 so that the coupling plate 320 does not move. , It is possible to securely fix the lateral buckling prevention clip member (3) to the corrugated plate (2). Of course, the coupling plate 320 may be fixed to the corrugated plate 2 by other methods such as welding or bonding.

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

In addition, in forming the fitting arrangement groove 31 that is 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 It is also possible to form the fitting arrangement groove 31 in a concave shape, but on the contrary, the fitting arrangement groove 31 may be formed in a concave shape from the bottom to the top. 12 is a schematic perspective view of the lateral buckling prevention clip member 3 according to another embodiment of the present invention in which the fitting arrangement groove 31 in the fastening part 30 is made in a concave shape from bottom to top. In addition, FIG. 13 is a schematic longitudinal front view corresponding to FIG. 7 showing that the lateral buckling prevention 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 transformed into a hole shape. 14 is a schematic perspective view of the lateral buckling prevention clip member 3 according to another embodiment in which the fitting arrangement groove 31 of the fastening part 30 is made into a hole shape, and FIG. 15 is shown in FIG. A schematic longitudinal front view corresponding to FIG. 7 showing that the illustrated transverse buckling prevention clip member 3 is coupled to the lattice reinforcing bar assembly 1 is shown. As shown in Figs. 14 and 15, the fitting arrangement groove 31 may be made in the form of a hole formed with an opening on the side. In this case, the upper chord 11 is a hole-shaped fitting arrangement through the opening formed on the side. It is placed in (31).

In the case shown in Figs. 12 and 13, the fitting arrangement groove 31 is made in a concave shape from the bottom to the top so that the upper chord 11 is wrapped by the fastening portion 30 so that the top and the side sides are wrapped in the transverse direction. While 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 so that the upper chord 11 ) Is limited in the transverse direction, 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 coupled with the lateral buckling prevention clip member 3 to be suspended. In this way, when the clip member 3 for preventing lateral buckling in the form of supporting the lower part of the upper chord 11 is used together with the floor coupling spacer 4 described above, the corrugated plate 2 is upwardly It is possible to exert an additional advantageous effect of adjusting the camber to match the upward camber of the lattice reinforcing bar assembly 1.

In general, it is desirable to lengthen the longitudinal span of the composite deck for the use of space in the building, and for this purpose, the longitudinal span of the lattice reinforcing bar assembly (1) rises upward so that the central part of the longitudinal span rises upward gently. An upward camber of a convex shape is provided to the lattice rebar assembly 1. The corrugated plate 2 may also be provided with an upward camber, but due to errors in manufacturing and processing, errors in transportation and storage, the upward camber applied to the lattice reinforcing bar assembly 1 and the corrugated plate 2 It is very difficult for the given upward camber to match completely. The lattice rebar assembly (1) has a large flexural stiffness, whereas the corrugated plate (2) has a relatively smaller flexural stiffness than the lattice rebar assembly (1). It may decrease, and accordingly, when the lattice reinforcing bar assembly 1 is installed on the corrugated plate 2, the lattice reinforcing bar assembly 1 and the corrugated plate 2 show a significant difference in camber. In the case of constructing a composite deck by pouring concrete despite the existence of an upward camber difference between the lattice rebar assembly (1) and the corrugated plate (2), the lattice rebar assembly (1) and the corrugated plate (2) due to the difference in camber ), the spacing between them is not uniform and irregularities may occur. Therefore, in order to prevent such a problem, it is desirable to "camber matching" in which the upward camber of the lattice reinforcing bar assembly and the upward camber of the corrugated plate are identical to each other.

In the present invention, the bottom coupling spacer 4 having the above-described configuration may be provided as needed. In this case, while the lower chord 12 of the lattice reinforcing bar assembly 1 is fastened to the floor coupling spacer 4, the lateral buckling prevention clip member 3 is disposed, and the top of the lattice rebar assembly 1 By placing the current 11 in the fitting arrangement groove 31 of the lateral buckling prevention clip member 3, the fastening portion 30 as in the embodiment shown in FIGS. 6 to 11 and the embodiment shown in FIGS. 14 to 15 When making the lower part of the virtual chord 11 supported, the lattice reinforcing bar assembly 1 is located hanging from the lateral buckling prevention clip 3, while the lower chord 12 of the lattice reinforcing bar assembly 1 is a floor 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 with the upward camber of the lattice rebar assembly 1.

In a state where 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 removed in the process of installing the lateral buckling prevention clip member 3 in the manner described above. It is adjusted according to the upward camber of the lattice reinforcing bar assembly 1, so that the corrugated plate 2 and the lattice reinforcing bar assembly 1 have the same upward camber. When the upward camber is matched, when the slab is constructed by pouring concrete on the upper surface of the corrugated plate 2 after the completed composite deck of the present invention is installed on the site, the lower surface of the slab becomes convex downward or is uneven. It does not become a form, and has the advantage of being able to stably maintain the shape and linearity originally designed.
