A plurality of deck plates 17 fixed to the support beam 13 by means, a wire mesh 19 disposed on the deck plates 17, and a concrete finishing layer 21 formed on the deck plates 17. ) The support beam 13 is covered with a fireproof coating 15 as an H beam.

The deck plate 17 is formed by bending a metal plate having a predetermined thickness, and has a plurality of protrusions 17a and grooves 17b. The bottom of the groove 17b is in contact with the support beam 13 and supports the deck plate 17 horizontally. Reference numeral 17c denotes a raised portion formed from the upper surface of the support beam 13 as a lower space of the protrusion 17a.

2 is a side cross-sectional view illustrating the problem of the slab structure shown in FIG.

As shown, a deck plate 17 is placed on the plurality of support beams 13, and a concrete finishing layer 21 is stacked on the deck plate 17. The concrete finishing layer 21 not only fills the groove 17b but also rises by a predetermined thickness from an upper portion of the protrusion 17a.

Hereinafter, one embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

3 is a view showing a honeycomb beam 31 according to the first embodiment of the present invention, Figure 4 is an exploded perspective view of the honeycomb beam (31). 5 is a side view of the honeycomb beam, and FIG. 6 is a cross-sectional view taken along line V-V of the honeycomb beam shown in FIG.

Basically, the honeycomb beam 31 according to the present embodiment takes the form of a general H beam, but has a structure having a support plate 31e in the middle web portion. The support plate 31e serves as a support for supporting the end of the deck plate as shown in FIG.

The honeycomb beam 31 has a first thickness 31a extending in the longitudinal direction with a predetermined thickness and width, a first web 31b fixed perpendicularly to the first flange 31a, and the first web 31b. A welding plate 31e welded to the web 31b and parallel to the first flange 31a, and fixed to the bottom of the drawing plate 31e and extending in parallel to the first web 31b. It consists of a 2nd web 31d and the 2nd flange 31c integrally with the width direction edge part of the said 2nd web 31d, and parallel to the said 1st flange 31a.

The first web 31b is integrally formed at the central portion in the width direction of the first flange 31a and extends in the longitudinal direction of the first flange 31a, and has a predetermined width and thickness. In particular, a plurality of grooves 31k are formed in the widthwise lower end portion of the first web 31b, that is, the end portion facing the support plate 31e. The groove 31k is a groove that is open to the support plate 31e once, but forms a through hole 31f when the support plate 31e is coupled to the first web 31b.

The support plate 31e is a metal plate having a predetermined width and thickness, and the width direction of the first and second webs 31b and 31d is interposed between the first web 31b and the second web 31d. Welded to the end. Reference numeral w denotes a weld. The support plate 31e is parallel to the first flange 31a and the second flange 31c. The metal material of the support plate 31e is the same as that of the first web 31b.

The second web 31d is symmetrical with the first web 31b with the support plate 31e interposed therebetween, and has a predetermined width and thickness and extends in parallel with the first web 31b.

Further, a plurality of grooves 31k are formed at an end portion of the second web 31d facing the support plate 31e. The groove 31k forms a through hole 31f by welding the second web 31d to the support plate 31e. The through hole 31f will be described later, and is a hole through which various electric wires or communication lines installed in the space 29 of the upper part of the ceiling board 25 can pass. The through hole 31f is symmetrical with the through hole 31f provided in the first web 31b.

The second flange 31c is integral with the second web 31d, has a predetermined thickness and a width, and extends in parallel with the first flange 31a.

7A to 7D are views for explaining a method of manufacturing the honeycomb beam 31 shown in FIG. 3.

In order to manufacture the honeycomb beam 31, a normal H beam 71 is first prepared, and the web 71a of the H beam 71 is cut along the cutting line z shown in FIG. 7A. . The cutting line z includes a plurality of inclined lines z2 and a horizontal line z1 connecting each inclined line z2. In particular, the length of each of the horizontal line (z1) and the slope line (z2) should be constant.

When the web 71a is cut up and down along the cutting line z, as shown in FIGS. 7B and 7C, the upper first flange 31a is lifted upwards, and then horizontally moved in the direction of arrow x. The horizontal lines z1 face each other.

In this state, the support plate 31e is disposed between the first web 31b and the second web 31d, and then the first web 31b is lowered to the second web 31d together with the support plate 31e. Let's do it. Finally, when the first and second webs 31b and 31d are in close contact with the upper and lower surfaces of the support plate 31e, the first and second webs 31b and 31d are welded to the support plate 31e.

Thereafter, as shown in FIG. 7D, the displaced portions at both ends are cut along the cutting line c to finish the process.

8 is a perspective view showing another example of the honeycomb beam according to the first embodiment of the present invention.

Referring to the drawings, it can be seen that the design of the through holes 31f formed in the first and second webs 31b and 31d is different from that in FIG. The design of the through hole 31f may vary depending on the case.

9 is an exploded perspective view of a honeycomb beam according to a second embodiment of the present invention, and FIG. 10 is a longitudinal sectional view of the honeycomb beam shown in FIG. 9.

Hereinafter, the same reference numerals as the above reference numerals denote the same members having the same function.

Referring to the drawings, it can be seen that the first web 31b and the second web 31d are directly welded together. That is, the butt weld is performed in a state where the widthwise lower end portion of the first web 31b and the widthwise upper end portion of the second web 31d are aligned.

In particular, the grooves (31k in FIG. 4) formed in the first and second webs 31b and 31d are aligned up and down to form a hexagonal through hole 31f.

On the other hand, the first support plate 35a and the second support plate 35b are welded to both side surfaces of the second web 31d, respectively. The first and second support plates 35a and 35b are metal plates having a predetermined thickness and a width, and extend in parallel with the second flange 31c. In addition, the heights of the first and second support plates 35a and 35b with respect to the second flange 31c may be the same or different. In some cases, the first and second support plates 35a and 35b may be coupled to the first web 31b.

In FIG. 10, the heights of the first and second support plates 35a and 35b with respect to the second flange 31c are the same, and the first support plate 35a has the second support plate 35b through the through hole 31f. It is exposed to the side. At this time, the first support plate 35a and the second support plate 35b are spaced apart by the thickness of the second web 31d. Therefore, when it is necessary to close the gap between the first support plate 35a and the second support plate 35b, a blocking plate 37 is used.

The blocking plate 37 blocks the gap between the first and second supporting plates 35a and 35b in a state where the blocking plate 37 is fitted into the through hole 31f and is fixed, so that the concrete placed on the upper portion of the second web ( Do not flow down to the 31d) side.

FIG. 11 is a view illustrating a slab structure to which a honeycomb beam shown in FIG. 3 is applied.

Referring to the drawings, the slab structure 41 of the present embodiment is constructed on the upper part of the living spaces 30a and 30b partitioned by the wall 23. The slab structure 41 has a plurality of honeycomb beams 31 arranged in parallel with each other, and both ends thereof across a support plate 31e of a neighboring hicom beam 31 among the plurality of honeycomb beams 31 so as to be horizontal. It is composed of a plurality of deck plates 17 and concrete finish layer 21 is placed on top of the deck plate (17). The lift portions 17c of the deck plates 17 are filled with end caps 18 for blocking the inflow of concrete.

In particular, the periphery of the through hole 31f in the upper portion of the support plate 31e is blocked by the pouring concrete. Therefore, the deck plate 17 is completely blocked with respect to each other, for example, the transmission of noise through the lifting unit 17c does not occur.

On the other hand, the support plate 31e and the second web 31d and the second flange 31c below the support plate 31e are wrapped with a fireproof coating material 15. The fireproof coating material 15 is laminated by spraying, and once blocks the through hole 31f of the second web 31d. The fireproof coating 15 may be perforated if necessary to pass a pipeline, a power line or a communication line through the through hole 31f, for example.

In addition, since the deck plate 17 spans the support plate 31e rather than the first flange 31a, its thickness h2 is thinner than the thickness of the conventional slab structure (h1 in FIG. The height is lowered.

FIG. 12 is a view illustrating a slab structure to which a honeycomb beam shown in FIG. 9 is applied.

The slab structure 41 shown in FIG. 12 includes a plurality of honeycomb beams 35 that are horizontally held across a bearing body (not shown), and a neighboring honeycomb beam 35 of the plurality of honeycomb beams 35. It consists of a deck plate 17 is supported on both ends of the second support plate (35b) to be horizontally supported, and the concrete finishing layer (21) is placed on top of the deck plate (17). Of course, the end cap 18 is fitted to the lift portion 17c of the deck plate.

As in Fig. 11, the through hole 31f formed in the first web 31b is completely sealed by the pouring concrete. Thus, each deck plate 17 is completely blocked off from each other. In particular, since the gap between the first and second support plates 35a and 35b is blocked by the blocking plate 37, there is no fear that the concrete will flow down when the concrete is poured.

In addition, as described above, since the deck plate 17 is supported by the first and second support plates 35a and 35b, the overall thickness h2 of the slab structure 41 is much thinner than in the case of FIG.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
