3 is a cross-sectional view of the floor panel P cut in a direction orthogonal to the longitudinal direction thereof, FIG. 4 is a partial longitudinal sectional view of the floor panel P cut along the longitudinal direction thereof, and FIG. Floor panel P
FIG. 1 is a perspective view showing a deck plate with a camber 1 as an example of a corrugated plate with a camber that forms the above.

Referring to these figures, the floor panel P is
The surface-side corrugated plate concave portion of the cambered deck plate 1 which is formed by continuously bending a thin iron plate or a thin steel plate into a corrugated shape in the width direction and curving convexly to the surface side along a longitudinal direction orthogonal to the width direction. A rigid rigid frame 4 is fixed to the corrugated concave portion 2a in a state where a linear rigid frame 4 is pushed into the concave plate 2a and the deck plate with camber 1 is forcibly elastically deformed in a horizontal state. Things. In addition, other than the deck plate, a corrugated folded plate used as a roof plate, or a thin iron plate or a thin steel plate for use in building or the like formed in a corrugated shape can be used.

The structure of the floor panel P will be described in more detail. As shown in FIG. 5, the deck plate 1 with a camber before being forcibly elastically deformed to a horizontal state is disposed on the front side along the longitudinal direction as shown in FIG. A camber that is curved in a convex shape is formed, and the height ρ of the camber is, as shown in FIG.
mm, it is about 5 to 15 mm.

This deck plate with camber 1 is
A corrugated plate concave portion 2a and a corrugated plate convex portion 3a are alternately formed in the width direction on the front surface side, and the corrugated plate concave portion 2a and the corrugated plate convex portion 3a on the front surface side are corrugated convex shape on the back surface side. Part 2b and corrugated plate concave part 3b
Is formed. The deck plate 1 is connected to a plurality (two in this case) in the width direction, and one end 1a of one deck plate 1 is related to the other end 1b of the other deck plate 1. It is to be fitted. In each connection end of each deck plate 1, a front surface side forms a concave portion 2a 'having a half width of the corrugated plate concave portion 2a, and a rear surface side forms a convex portion 2b'.

As can be seen from FIGS. 1 to 3, each surface side corrugated plate concave portion 2 a of the deck plate 1 with a camber has:
A rigid bone frame 4 made of a hat-shaped steel is pushed into and closely adhered to its bottom surface, and a rigid bone frame 4 'made of a channel steel is similarly pushed into and tightly fitted to a half-width concave portion 2a'. A rigid holding frame 7 having a U-shaped cross section for holding both ends of the deck plate 1 and both ends of the rigid bone frames 4 and 4 'is fitted to both longitudinal ends of the deck plate 1 with camber. It is stuck together. This rigid holding frame 7 is made of, for example, a channel steel.

The rigid bone frames 4, 4 'are fixed to the bottom surface of the concave portion 2a on the front side by welding in a state where the deck plate 1 with the camber is forcibly elastically deformed in a horizontal state. This welding is performed, for example, by plug (plug) welding, and the welding location is indicated by W in FIG. The fixation of the rigid bone frames 4 and 4 'to the deck plate 1 is not limited to welding as described above, but can be performed by rivets, caulking, or the like. Although not shown, the rigid holding frame 7 is fixed to the deck plate 1 and the rigid frame 4 by, for example, spot welding. A rigid holding frame 7 having a U-shaped cross section is fitted to both ends of the deck plate 1 and the rigid bone frames 4, 4 ', and is fixed by welding or the like, so that the rigid bone frames 4, 4' are decked. The rigid frames 4 and 4 ′ are attached to the corrugated plate concave portions 2 a of the deck plate 1 before the rigid holding frames 7 are fitted and fixed to both ends of the deck plate 1 because the rigid frame frames 4 and 4 ′ are closely attached to the bottom surface of the corrugated plate concave portions 2 a of the plate 1. It is not necessary to fix to 2a by welding or the like.

According to the floor panel P having the above-described structure, the linear rigid frame 4 is pushed into the concave portion 2a on the front side of the deck plate with the camber, forcing the deck plate 1 to a horizontal state. The rigid bone frame 4 is closely attached to the corrugated concave portion 2a in a state where the rigid bone frame 4 is elastically deformed. Of the deck plate 1 with a camber, the stress is generated by the reaction force so as to maintain a continuous shape before deformation. Therefore, when the deck plate 1 is used as a floor panel, the load is applied to the panel by the stress. This offsets the deformation of the panel to a small extent.

Therefore, even if a thin deck plate 1 is used, a floor panel P having a small deformation equivalent to a sufficiently rigid panel can be formed, and the weight of the floor panel P can be reduced. Further, the floor panel P is excellent in so-called vibration damping property for reducing vibration by the elasticity of the deck plate with camber 1 and its corrugated plate structure.

In using the floor panel P,
As shown in FIG. 2 and FIG. 3, for example, when mounting and fixing on a beam H such as an H-section steel, the whole floor panel P is made of metal. It can be easily and firmly fixed to the beam member H by ordinary mounting means such as bolting. In addition, as shown by a virtual line in the figure, an overlay board Q such as a particle board or a structural plywood is placed on the floor panel P.

In the above-described floor panel P, the linear rigid frame 4 is pushed into the concave portion 2a on the front surface side of the deck plate 1 with camber. The plate 1 may be pressed into the corrugated concave portion 3b from the back side of the plate 1 and fixed thereto.
Further, the camber attached to the deck plate 1 may be formed so as to be convexly curved on the back surface side of the deck plate 1.

Next, a method of manufacturing the floor panel P will be described with reference to FIGS.

First, a deck plate 1 with a camber is formed, for example, in which a thin steel plate is continuously bent in a corrugated shape in the width direction, and is convexly curved to the surface side along a longitudinal direction orthogonal to the width direction. In this case, after a thin steel plate is continuously bent into a corrugated plate to form a deck plate, a camber that is curved in a convex shape is attached to the surface side of the deck plate to form the corrugated plate 1 with a camber, or While continuously bending the thin steel sheet into a corrugated sheet, a camber that curves in a convex shape may be attached to the thin steel sheet at that time to form the corrugated sheet 1 with a camber.

As shown in FIGS. 6 and 8, each surface side corrugated plate concave portion 2a of the camber-equipped deck plate 1 having a camber curved convexly on the plate surface side.
Then, each rigid frame 4 made of, for example, a hat-shaped steel is pushed into the deck plate 1 with a camber to be forcibly elastically deformed in a horizontal state.
The two flange portions 4a, 4a are fixed to the bottom surface of each corrugated plate concave portion 2a by plug welding W to obtain a state as shown in FIGS.

The plug welding W is performed at both ends of each rigid frame 4 and a plurality of intermediate portions thereof as shown in FIGS. 7 and 9, but may be performed only at both ends of each rigid frame 4. That is,
In the case of this manufacturing method, as can be seen from FIGS.
Each rigid bone frame 4 is pushed into the corrugated plate concave portion 2a on the convex plate surface side where the camber of the deck plate 1 with a camber is convexly curved. If the rigid bone frame 4 and the corrugated plate concave portion 2a are welded, the corrugated plate concave portion 2a is brought into close contact with the flange portion 2a of the rigid bone frame 4 due to its elastic restoring force at an intermediate portion thereof, so that it is not always necessary to perform welding. Absent. Therefore, welding work can be omitted, and the work can be simplified accordingly.

By the way, each rigid bone frame 4 is pushed into the back side corrugated concave portion 3b (see FIG. 5) of the deck plate 1 with the camber opposite to the convex plate surface side where the camber is convexly curved. In the case where each rigid bone frame 4
The corrugated plate 3 on the back side of the deck plate 1
It is necessary to perform welding with b, and a very long time and labor are required for the welding operation.

The method for fixing the rigid bone frame 4 to the corrugated concave portion 2a (or 3b) of the deck plate 1 is not limited to the above-described welding, but may employ rivets, caulking means, or the like. Can be.

As described above, the rigid bone frame 4 is pushed into the corrugated concave portion 2a of the deck plate 1 with a camber, and the rigid plate 4 is waved while the deck plate 1 is forcibly elastically deformed to a horizontal state. After being fixed to the plate concave portion 2a, a rigid holding frame 7 having a U-shaped cross section for holding both ends of the deck plate 1 and both ends of each rigid bone frame 4 at both ends in the longitudinal direction of the deck plate 1 (see FIG. 1 and FIG. 4) and fixed by welding. Alternatively, the rigid bone frame 4 may be simply fixed to the corrugated plate concave portion 2a by pushing the rigid bone frame 4 into the corrugated plate concave portion 2a of the cambered deck plate 1 and elastically deforming the deck plate 1. By fixing the rigid holding frame 7 to both ends in the longitudinal direction of the deck plate 1 as described above, warpage and deformation of the deck plate 1 in the width direction are prevented, and the floor panel P is always held in a horizontal plate shape. Can be.

In the manufacturing method described above, the rigid bone frame 4 is pushed into the corrugated concave portion 2a of the deck plate 1 with a camber, and the rigid plate 4 is horizontally elastically deformed. After being fixed to the concave portion 2a by welding or the like, a rigid holding frame 7 having a U-shaped cross section for holding both ends of the deck plate 1 and both ends of each rigid bone frame 4 at both ends in the longitudinal direction of the deck plate 1. (See FIG. 1 and FIG. 4). The rigid plate 4 was pressed into the corrugated concave portion 2a of the deck plate 1 to deform the deck plate 1 horizontally and elastically. In this state, the rigid holding frame 7 may be fitted to both ends of the deck plate 1 in the longitudinal direction, and the rigid holding frame 7 may be fixed to the rigid bone frame 4 and the deck plate 1 by welding.

In this case, as indicated by phantom lines in FIG. 8, the rigid holding frames 7 having a substantially U-shaped cross section with a lower flange wider than the upper flange are arranged on both ends of the deck plate 1 with a camber. The rigid bone frame 4 is pushed into the corrugated concave portion 2a of the deck plate 1,
May be elastically deformed to a horizontal state, and at the same time, the rigid bone frame 4 may be plug-welded to the lower flange of the rigid holding frame 7 together with the corrugated concave portion 2a of the deck plate 1. In addition, when the rigid holding frame 7 is fixed, the fixing method is not limited to welding.
Rivets, caulking means, and the like can be employed.

Rigid bone frame 4 used for floor panel P of the present invention
In addition to the hat-shaped steel described above, a channel steel 14, a square steel 24, and an H-shaped steel 34 as shown in FIGS. 10A, 10B, and 10C can be used. In addition, these hat-shaped steel 4, grooved steel 14, square steel 24, and H-shaped steel 3
The rigid frame made of 4 or the like may have a thickness of about three times the thickness of the deck plate 1 with a camber. In the embodiment of the floor panel P of the present invention, the thickness of the deck plate 1 with a camber is about 0.8 to 1.6 m.
m, the thickness of each of the rigid bone frames 4, 14, 24, 34 is about 2.4 to 4.8 mm, and the width of the corrugated concave portions 2a, 3b of the deck plate 1 with camber is about 100.
The depth is about 50 to 100 mm.

[0030]

According to the first and third aspects of the present invention, a thin steel plate or a thin steel plate is continuously bent in a corrugated shape in the width direction, and the surface side is arranged along the longitudinal direction orthogonal to the width direction. Or using a corrugated sheet with a camber that curves convexly on the back side,
A rigid rigid frame is pushed into the concave portion of the corrugated sheet on the front side or the back side of the corrugated sheet with the camber, and the rigid frame is waved in a state where the corrugated sheet with the camber is forcibly elastically deformed to a horizontal state. Since it is designed to be fixed to the concave part of the plate, the reaction force of the same size acts in the opposite direction to the corrugated plate with camber by the pushing force by the rigid bone frame, and the camber is attached by the reaction force. A stress is generated in the entire corrugated sheet so as to maintain a continuous shape before deformation, and when used as a floor panel, this stress cancels out the load applied to the panel, thereby suppressing deformation of the panel to a small extent.

Therefore, even if a thin corrugated sheet is used, a floor panel with a small deformation equivalent to a sufficiently rigid panel can be formed, and the weight of the floor panel can be reduced. In addition, this floor panel is excellent in so-called vibration damping, which reduces vibrations, due to the elasticity of the corrugated plate with camber and its corrugated plate structure.

In using the floor panel,
When this floor panel is mounted and fixed on a beam made of shaped steel, the whole floor panel is made of metal, so it is well-adapted to the beam, and it is attached by ordinary mounting means such as welding or bolting. It can be easily and firmly fixed to the beam, and the construction efficiency can be improved.

As described in the second and fourth aspects, rigid holding frames for holding both ends of the corrugated sheet and both ends of each rigid frame are fixed to both longitudinal ends of the corrugated sheet with camber. By doing so, warpage in the width direction of the corrugated sheet with camber can be prevented, and the floor panel can always be held in a horizontal plate shape.

According to the fifth aspect of the present invention, the rigid bone frame is pushed into the corrugated concave portion on the plate surface side of the corrugated corrugated camber where the camber is convexly curved.
If the rigid bone frame and the corrugated plate concave portion are fixed only at two places at both ends of the rigid bone frame, the corrugated plate concave portion inevitably comes into close contact with the rigid bone frame due to its elastic restoring force at the intermediate portion. Therefore, the fixation at the intermediate portion is not required, and the fixation work is accordingly simplified.
