DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite panel building material made of concrete integrated with a metal outer frame material.

[0002]

2. Description of the Related Art As a structural member such as a floor, an outer wall, a roof or an erected floor of a building, A is obtained by curing and curing cellular concrete.
LC plates are widely used. Since the ALC board made of such cellular concrete has high water absorption and its ends are brittle and easily chipped, a composite panel building material in which the cellular concrete is reinforced by being surrounded by a metal plate is sometimes used.

Conventionally, as such a composite panel building material, concrete is filled up to the protruding height of the side plate inside a metal outer frame material surrounding the periphery of the bottom plate with a side plate protruding to the surface side, and this filling is performed. Some concretes are manufactured by curing hardened concrete (see, for example, Japanese Utility Model Publication No. Hei 3-30489).

[0004]

In the above-mentioned conventional composite panel building material, since there is no means for changing the mounting position with respect to the beam material, it is not possible to immediately respond to a change in the cross-sectional size of the beam material. Installation work was complicated. In view of such circumstances, an object of the present invention is to make it possible to attach a composite panel building material to a beam at various positions, thereby simplifying the attaching work.

[0005]

In order to achieve the above object,
The present invention has taken the following technical measures. That is, the present invention relates to a metal outer frame material surrounding a peripheral edge of a bottom plate with a side plate protruding to the surface side thereof, and a concrete which is filled up to the projecting height of the side plate in this outer frame material and cured and cured. In the composite panel building material provided with: a concave groove that opens to the outside of the outer frame material is formed by recessing the middle part of the bottom plate into the inner side of the outer frame material, and the inner side of the concave groove is a mounting bolt. And the opening side of the concave groove is a narrow portion that can pass through the shaft portion of the mounting bolt but cannot pass through the head portion of the bolt. (Claim 1).

In this case, for the reason described later, a rim portion is formed at the protruding end of the side plate so as to protrude inside the frame of the outer frame material, and the free end inside the rim is embedded in concrete. It is preferable to displace it toward the bottom plate as described above (claim 2). In addition, it is preferable to fix the end of the reinforcing bar embedded in the concrete to the free end of the edging portion for the reason described later (claim 3).

[0007]

According to the present invention, the inner side of the concave groove 12 is attached to the mounting bolt 14.
Since the shaft portion 17 of the mounting bolt 14 can pass through the opening side of the concave groove 12 but the narrow portion 18 cannot pass through the head 15, the mounting bolt 14 is The shaft portion 17 can be slidably housed in the concave groove 12 with the shaft portion 17 protruding from the back surface of the outer casing frame member 2.

On the other hand, according to the second aspect of the present invention, since the free end 11 inside the frame of the edging portion 9 is embedded in the concrete 3, the free end 11 of the edging portion 3 is rolled up upward or the edging portion is formed. 9 can be effectively prevented from bulging upward. According to the third aspect of the present invention, the edge portion 9 also functions as a mounting portion for the reinforcing bar 4, and it is not necessary to newly provide a mounting base for the reinforcing bar 4 in the outer frame 2 or the number thereof is greatly reduced. Can be reduced.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 and 2, a composite panel building material 1 according to the present embodiment has a skin frame material 2 made of a relatively thin steel plate.
And concrete 3 which is filled and hardened in the frame material 2 and a mesh reinforcing bar 4 buried in the concrete 3.

The outer frame member 2 is formed by bending a single steel sheet into a predetermined shape as shown in FIG. 2 by press molding or the like. 2 (upper side in FIG. 2). Each side plate 6 is bent substantially perpendicularly to the bottom plate 5, and the concrete 3 in the outer frame 2 is filled to the full height of each side plate 6.

When the concrete 3 to be cast therein is uncured, it functions as a disposal form, and after the concrete 3 has been cured and hardened,
It functions as a reinforcing member for improving the tensile strength of the concrete 3 and preventing chipping of the end. In particular, when cellular concrete (ALC) is adopted as the concrete 3 to be filled into the outer frame material 2 for weight reduction, the cellular concrete has a high water absorption and its ends are fragile and easily chipped. It is significant that the concrete 3 is covered with the outer frame material 2.

Four side plates 6 forming the periphery of the outer frame member 2
Among them, a fitting ridge 7 having a U-shaped cross section extends along the longitudinal direction at the upper and lower central portions of the widthwise right side plate 6R, and the upper and lower central portions of the widthwise left side plate 6L. A fitting groove 8 into which the fitting ridge 7 is fitted extends in the longitudinal direction. For this reason, as shown in FIG. 1, by fitting the fitting ridge 7 of the other composite panel building material 1 into the fitting groove 8 of the other composite panel building material 1, the composite panels adjacent in the width direction are formed. The building materials 1 and 1 can be joined flush with each other.

As shown in FIG. 4, the side plates 6E at both ends in the longitudinal direction of the outer frame member 2 are formed flush with each other without the ridges 7 and the concave grooves 8. At the protruding end (upper end in FIG. 2) of each side plate 6, a rim portion 9 protruding inside the frame of the outer skin frame member 2 is bent. The edge portion 9 has a root bent substantially perpendicularly to the side plate 6, and a hanging portion 1 having an end inside the frame bent downward toward the bottom plate 5.
0, and the free end 11 of the rim 9 is embedded in the concrete 3 via the hanging portion 10.

As described above, since the edging portion 9 is embedded in the concrete 3 at the portion of the hanging portion 10 inside the frame, even if the edging portion 3 is rubbed when the composite panel building material 1 is transported or the like. In addition, it is possible to prevent the free end 11 of the edging portion 3 from rolling up. In addition, even if the side plate 6 attempts to deform in a direction away from the concrete 3 due to thermal stress or repeated stress after construction, the hanging portion 10
Does not dig into the concrete 3, such deformation does not occur, and therefore, the rim 9 does not bulge upward as a whole.

Further, in the case of the present embodiment, an end portion of the bottom plate 5, the side plate 6, the edging portion 9, and the hanging portion 10 constitute a substantially C-shaped frame sectional structure at the outer peripheral end portion of the outer cover member 2. Therefore, there is also an advantage that the bending strength of the end portion of the composite panel building material 1 is greatly improved. The mesh reinforcing bar 4 is buried in the concrete 3 to improve its tensile strength. The mesh reinforcing bar 4 is formed by framing a steel wire rod in a lattice pattern at a constant pitch. By being welded to the free end 11) of the portion 9, the composite panel building material 1 is arranged slightly above the surface.

Therefore, in this case, the hanging portion 1 of the edging portion 9
0 also functions as a mounting portion for the mesh reinforcing bar 4, so that it is not necessary to provide a new mounting base for the mesh reinforcing bar 4 in the outer casing frame material 2 or the number thereof can be significantly reduced. The labor required for the operation is reduced. As shown in FIGS. 2 and 3, a concave groove 12 is formed in the middle of the bottom plate 5 in the width direction so as to open downward by recessing the bottom plate 5 into the inside of the outer casing frame 2. The concave grooves 12 are formed at three places on the center of the bottom plate 5 in the width direction and on both left and right sides, and each of the concave grooves 12 extends over both longitudinal ends of the outer casing frame member 2.

Further, between the concave grooves 12 in the bottom plate 5, reinforcing ribs 13, which extend in the width direction and swell inwardly of the outer frame member 2, are formed at a constant pitch in the longitudinal direction of the bottom plate 5. Thereby, the bending strength in the width direction of the composite panel building material 1 is improved, and the outer frame material 2 of the concrete 3 is improved.
To prevent lateral displacement. Each of the concave grooves 12 is formed in a substantially T-shape in cross section, and the back side of the concave groove 12 is capable of storing a head 15 of a mounting bolt 14 for mounting the composite panel building material 1 to a beam or the like. Portion 16, and the opening side of the concave groove 12 is attached to the mounting bolt 1.
4 is a narrow portion 18 that can pass through the shaft portion 17 but cannot pass through the head portion 15 of the bolt 14.

The mounting bolt 14 has its head 15 housed in the housing portion 16 of the concave groove 12 so that the shaft portion 17 protrudes from the back surface of the outer casing frame member 2. The frame member 2 is slidably engaged with the concave groove 12 along the longitudinal direction. The shaft 1 of the mounting bolt 14
