Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to, for example, a deck plate constituting the bottom of a floor or ceiling, and in particular to an improvement in the end structure thereof.

[Conventional technology]

Fig. 10 is a plan view showing the end of one protrusion of a conventional deck plate, Fig. 11 is a front view of this end, and Fig. 12 is a side view of this end. , 2 is a flat belt-shaped mountain surface forming the top, 4 is a pair of belt-shaped slopes that continue diagonally downward from both side edges of this mountain surface, and 6 is a flat surface that continues laterally from the side edges of this slope. This is a band-shaped valley surface. The mountain portions 2, slope portions 4, and valley portions 6 are formed alternately in this order, and the outer edge of one of the outermost valley portions 6 is provided with a groove as shown in FIGS. 13 and 14. A rising lip 8 that continues upward is formed at the top. The mountain surface portion 2, the slope portion 4, the valley surface portion 6, and the rising lip 8 are integrally formed by bending a single steel plate, and the mountain surface portion 2 and the slope portion 4 have a substantially U-shaped cross section. A protruding portion 10 is formed. Projection part 1
The end 12 of 0 is obliquely crushed toward its longitudinal edge, and the edge has raised lips 8 at both ends.
A flat wave part 16 is formed in the center of the wave part 14 with a height equal to or higher than the height of the ridge part 10. It's being shrunk.

Conventional deck plates are constructed as described above, and are used by laying a plurality of plates together with their ends placed on beams made of H steel or the like. At this time,
The two deck plates adjacent in the width direction are the first
As shown in FIGS. 3 and 14, the rising lip 8 is engaged with the wave portion 14 and wrapped.
Concrete is poured to a predetermined thickness on top of the deck plate to form a floor or ceiling.

[Problems to be solved by the invention] In the conventional deck plate as described above, the height of the wave portion 14 formed at the edge of the end portion 12 of the protrusion portion 10 is high, and the opening area is large. When concrete is poured, there is a problem in that the concrete enters the corrugated portion 14 and leaks downward. In addition, since the height of the above-mentioned corrugated portion 14 is high, when stacking and bundling for transportation etc., the corrugated portion 14 of the lower deck plate will bite into the corrugated portion 14 of the upper deck plate, and the deck plate may be removed at the site. There was a problem in that it was difficult to remove. Furthermore, there was also the problem that they were bulky when stacked and tied.

[Means for solving problems]

The deck plate according to this invention includes a band-shaped mountain surface forming the top, a pair of band-shaped slopes extending downward from both side edges of the slope, and a band-shaped slope continuing laterally from the side edges of the slope. In a deck plate formed by alternately forming troughs and ridges, and pressing obliquely the longitudinal ends of the ridges formed by the ridges and the slopes toward the edges, the ridges are formed alternately. In order to reduce the length of the edge of the end of the ridge to the width of the ridge, the ridges are distributed in a scattering manner so that the height and width of the opening are approximately equal. The edge is terminated by a number of small waves.

[Function] In this invention, since the area and height of the openings in the corrugations are small, concrete will not leak during concrete pouring. In addition, when a large number of deck plates are stacked or tightly tied together, the protrusions engage with each other, but gaps corresponding to the height of the corrugations are formed between the deck plates. The friction area of the rib-like rising edges is narrower than that of conventional examples, and when one deck plate at the top of a stack of deck plates is warped, the protrusions and each rising portion deform evenly. Because it can be easily separated from the ridges of the lower deck plate and each rising part, the overall height when stacked is low and not bulky, and at the same time, each deck plate can be separated from the stacked deck plates one by one. It can be easily peeled off.

〔Example〕

Fig. 1 is a plan view showing the end of one protrusion of a deck plate showing an embodiment of this invention, Fig. 2 is a front view of this end, and Fig. 3 is a side view of this end. 2 to 12 are exactly the same as the conventional deck plates mentioned above. Reference numeral 18 denotes a plurality of low-height corrugated portions formed on the longitudinal edge of the end portion 12 of the protrusion portion 10 . As shown in FIG. 4, a notch 20 is formed at the longitudinal end of the rising lip 8 by partially cutting it out.

In the deck plate configured as described above, the longitudinal end of the rising lip 8 is partially cut out, so the deck plate can be wrapped and spread as shown in FIGS. 4 and 5. In this case, the wave portion 18 and the rising lip 8 will not collide.

In the above embodiment, a plurality of small waves 18 are formed on the edge of the protrusion 10, but as shown in FIGS. 18 may be left and folded. Furthermore, the same effect can be expected even if the longitudinal ends of the rising lip 8 are formed partially flat as shown in FIG.

[Effect of idea]

As explained above, this idea is to disperse the protrusions in a scattering manner so that the length of the edge of the end of the protrusion is reduced to the width of the protrusion, each having a height of approximately Since the edge is terminated by a number of corrugations with equal height and small opening height and width, the area of the corrugation openings can be made small, thus reducing leakage of concrete from the corrugation openings. In addition, it is possible to reduce the mutual digging of the corrugated parts of the deck plates, and it is also possible to reduce the bulk caused by stacking, which improves transportation efficiency, storage efficiency, cargo handling, etc. There is an effect.
