Therefore, the three-dimensional truss and the substrate are fixed by inserting and fastening the engaging pieces of the truss into the accommodating portion of the substrate, whereby welding is unnecessary and a deck plate with a truss in which the three-dimensional truss and the substrate are integrally formed can be configured. have.

An embodiment of the present invention will be described based on the drawings.

First, the configuration of the three-dimensional truss 10 used in the practice of the present invention will be described with reference to FIG.

As shown in Fig. 7, two corrugated bars 4 and 4 are arranged in parallel in an isosceles triangle shape with the upper main reinforcing bar (upper reinforcing bar) 1 as a vertex. The upper main reinforcing bars 1 and the corrugated upper ends 5 and 5 of both corrugated bars 4 are welded to each other. Further, the lower end portions 6 and 6 of the corrugated reinforcing bar 4 are bent substantially horizontally toward the outward direction, and the bent portions are the engaging pieces 7 and 7.

Further, the lower main reinforcing bars (lower reinforcing bars) 8, 8 provided in parallel with the corrugated reinforcing bars 4 are welded and fixed to the outside of the corrugated reinforcing bars 4, 4, respectively. The three-dimensional truss 10 is constituted as described above.

The three-dimensional truss 10 may be elastically deformed so that the lower end 6 side (coupling piece 7) of the corrugated reinforcement (4, 4) is close.

In the present embodiment, the upper main reinforcing bar 1 is a peak, and two corrugated bars 4 and 4 are welded to both sides of the circumferential surface, respectively, but the present invention is not limited thereto, and is shown in FIGS. 8A and 8B. As described above, the corrugated reinforcing bar 4 may be formed along the upper outer circumferential surface of the upper main reinforcing bar 1 and may be formed by welding their contact portions.

Moreover, the board | substrate (deck plate) 17 used for this invention is demonstrated. As shown in Fig. 3 and Fig. 5, connecting tubs 13 and 14 are formed at the edges of the connection side ends of the plate members having a predetermined length corresponding to the lengths of the three-dimensional trusses. In addition, the receiving part 15 corresponding to the engaging piece 7 of the said three-dimensional truss 10 is formed in the substantially center part of a board | plate material. The receiving portion 15 is erected upward from the upper surface of the plate 12 by the diameter portion of the corrugated steel 4 (the height of the joining piece 7), and further bent in the transverse direction toward the inside. It is formed of a jaw-shaped protrusion. As shown in Fig. 3, a predetermined plate is bent to form the substrate 17 so as to have the above shape. The said board | substrate 17 coats at least the lower surface 19 with a predetermined | prescribed color before or after bending of a board | plate material. In addition, the width D and the length L of the substrate are appropriately selected and manufactured according to the use place.

Another embodiment of the present invention for the substrate is shown in FIG.

As shown in the figure, at least one or more reinforcing protrusions 31 are formed on the bottom surface between the connecting tubs 13 and 14, and the housing in which the engaging pieces 7 upper side of the three-dimensional truss 10 comes into contact with each other. The fixed protrusion 32 is formed in the Daeung surface of the part 15. Therefore, the reinforcement protrusion 31 of the substrate 17 can sufficiently withstand the vertical load due to the concrete placing on the deck, and also the coupling piece 7 to the receiving portion 15 by the fixing protrusion 32. When is inserted, the flow can be suppressed as much as possible.

Meanwhile, referring to the process of coupling the coupling piece 7 of the three-dimensional truss 10 to the receiving portion 15 of the substrate 17, the three-dimensional truss 10 is disposed on the upper side of the substrate 17 (FIG. 1A), the lower ends 6 and 6 of the three-dimensional truss 19 are compressed to be close to each other (arrows 21 and 21 directions) and elastically bent (see FIG. 1B), and are mounted on the upper surface of the substrate 17 as it is ( See FIG. 1C). Subsequently, the pressure is released to insert and stop the engaging piece 7 of the three-dimensional truss 7 into the receiving portion 15 of the substrate 17 to fix the three-dimensional truss 10 to the substrate 17. Thus, the deck plate 22 with a truss is comprised. In the deck plate 22 with the truss configured as described above, the end edges 3, 3, 9, and 9 of the upper and lower cast iron bars 1 and 8 of the three-dimensional truss 10 are the end portions of the substrate 17. It protrudes outward from the edges 20 and 20, and the connecting rod 23 for connecting the end edges of the upper and lower cast irons 1 and 8 by beams is fixed. The connecting section 23 is welded to the three-dimensional truss 10 in advance, or welded to the three-dimensional truss at the construction site.

The deck plate 17 to which the truss is attached is the same as a conventional deck plate, when building a concrete floor in a building, as shown in FIG. The substrates 17, which have a predetermined number in parallel to each other and are adjacent to each other, are connected to each other by the connecting tubs 13 and 14 for use. At this time, as shown in Fig. 4, the connecting rods 23 and 23 are fixed to and attached to the flanges 25 of the steel beams.

On the deck plate 22 to which the truss was attached, a floor may be constructed after concrete casting (a support member between lower slabs is unnecessary in principle) by placing a predetermined floor beam. Since the lower surface 18 of the board | substrate 17 of the deck plate 22 with a truss is apply | coated, it is also possible to comprise a ceiling surface as it is.

In the joining process of this embodiment, although the joining work of the joining pieces 7 and 7 of the three-dimensional truss 10 and the receiving portions 15 and 15 of the substrate 17 was performed on both sides at once, the joining piece on one side was used. After connecting the 7 and the receiving portion 15 to each other by pressing the three-dimensional truss 10 to elastically bend (see Fig. 2) by inserting the other engaging piece (7) into the receiving portion 15 to be coupled to each other It is also possible (see Fig. 1D).

In addition, insertion of the coupling piece 7 may connect one coupling piece 7 to all or one or more of each waveform at a time (not shown).

In the above embodiment, the lower cast bars 8 and 8 are fixed to the outside of the corrugated bars 4 and 4, but can also be fixed to the inside (dashed line 8a in Fig. 7C).

In the above embodiment, the connecting rod 23 is used for steel frame beams, but in the case of using a frame for beams, a connecting rod of another conventional structure is used (not shown). It is also possible not to use the connection between the connections if a means for temporarily stopping the other steel beams or beam frame (not shown).

In addition, although the board | substrate 17 was apply | coated in the said Example, it is also possible to superimpose various sheets or finishing boards on the lower surface 18 (not shown).

In addition, in the above embodiment, the substrate 17 is formed by bending a sheet material, but may be configured at best by a receiving portion having the same structure made of a separate member (not shown).

In the above embodiment, the three-dimensional truss 10 is provided close to one side of the substrate 17, but may be provided in the center portion (not shown).

In the above embodiment, the three-dimensional truss 10 is provided on one substrate 17. However, two or three or more three-dimensional trusses 10 may be provided in parallel (not shown).

In the above embodiment, the coupling piece 7 of the three-dimensional truss 10 and the receiving portion 15 of the substrate 17 may have other structures as long as mutual coupling is possible. For example, although the accommodating part 15 of the board | substrate 17 consisted of the cross-section L-shaped protruding tank over the whole length, the protruding part is formed in every position of the engaging pieces 7 and 7 of the three-dimensional truss 10, It may be configured (not shown). In addition, when such a receiving part is comprised, the lower end part 6 of the corrugated steel reinforcement 4 of a three-dimensional truss may be made into the engagement piece as it is, without lowering | bending in substantially horizontal direction (not shown).

The present invention described above is not limited to the above-described embodiment and the accompanying drawings, and various substitutions, modifications, and changes are possible within the scope without departing from the technical spirit of the present invention. It will be apparent to those who have knowledge.

As described above, according to the present invention, since the three-dimensional truss and the substrate are stopped and fixed to form a deck plate with a truss, welding is unnecessary and there is an effect of simplifying the manufacture of the truss-attached deck plate. . In addition, since no welding or metal mounting structure is necessary, the finishing material does not become dirty even when the coating or various finishing materials are provided in advance on the substrate. Moreover, since welding is unnecessary, it is not necessary to limit the material of the finishing material of a board | substrate or a lower surface of a board | substrate to an electrically conductive material, aluminum-type, resin-type, etc. are possible, and the range of material selection can be expanded.

Therefore, the ceiling of a structure can be previously finished by a color steel plate and various finishing materials on the lower surface of a board | substrate. As a result, construction of a scaffold for finishing the ceiling is not necessary, so that construction can be simplified and air can be shortened as a whole.

Moreover, since the accommodating part is formed in a board | substrate, there exists an effect which reinforces a board | substrate.
