Description

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 A is made by curing and curing cellular concrete as a structural member such as a building floor, outer wall, roof or erected floor.
LC plates are widely used. Since an ALC plate made of such a cellular concrete has high water absorption and its edges are brittle and easily chipped, it may be a composite panel building material in which the cellular concrete is reinforced by surrounding the cellular concrete.

Conventionally, as such a composite panel building material, concrete is filled up to the projecting height of the side plate inside a metal outer frame material which surrounds the peripheral edge of the bottom plate with the side plate projecting to the surface side, and this filling is performed. There is one manufactured by curing and curing concrete (for example, see Japanese Utility Model Publication No. 3-30489).

[0004]

In the composite panel building material described in the above publication, since the protruding end of the side plate constituting the outer peripheral edge of the composite plate remains a free end and is not treated at all, the concrete on the protruding end side of the side plate is Reinforcement is still not perfect, and the concrete in the outer frame is often chipped from the protruding end of the side plate.

Therefore, in order to prevent the concrete from chipping from the projecting end side of the side plate, the projecting end of the side plate is provided with an edging portion projecting to the inside of the outer frame member to form the side plate in an inverted L-shape in cross section. It is possible. However, if the side plate is simply formed into the inverted L-shape in cross section to form the edging portion, the free end inside the frame of the edging portion is rolled up due to rubbing during the transportation of the building material, or the edging portion is caused by thermal stress or assembly stress after the construction. May swell overall.

[0006] When such curling or bulging of the edging portion occurs, moisture stays in the gap formed between the edging portion and concrete to deteriorate the concrete or the outer frame material, and In addition to reducing durability, when the composite panel building material is used as a floor board, inconveniences such as catching a foot by the bulging edging portion may occur.

On the other hand, in order to solve this, it is conceivable to make the side plate and the edging portion thick so as to prevent the deformation, but this increases the weight of the composite panel building material and raises the material cost. . In view of such a situation, the present invention is a composite panel building material in which an edge portion is formed on a metal outer frame material, and the outer edge frame material including the side plate and the edge portion is not thickened, and the edge portion is rolled. The purpose is to be able to prevent bulging.

[0008]

In order to achieve the above object,
The present invention has taken the following technical means. That is, the present invention is a metal outer frame member that surrounds the peripheral edge of the bottom plate with a side plate protruding to the surface side, and concrete that is filled and cured to the protruding height of the side plate in the outer frame member. In the composite panel building material including, a edging portion protruding toward the inside of the outer frame material is formed at the protruding end of the side plate, and the edging portion has a free end inside the frame embedded in the concrete. It is displaced to the side of the bottom plate as described above (Claim 1).

In this case, 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 2). In addition, a recessed groove that opens to the outside of the outer frame material is formed by recessing the middle part of the bottom plate toward the inner side of the outer frame material, and the back side of this groove can store the head of the mounting bolt. Further, the opening side of the groove may be a narrow portion through which the shaft portion of the mounting bolt can pass but the head portion of the bolt cannot pass (claim 3).

[0010]

In the present invention, the free end 11 of the edging portion 9 inside the frame is provided.
Since it is embedded in the concrete 3, it is possible to effectively prevent the free end 11 of the edging portion 3 from being rolled up and the edging portion 9 as a whole to be bulged upward. On the other hand, claim 2
In the invention described in (1), the edging portion 9 also functions as a mounting portion for the reinforcing bars 4, and it is not necessary to newly provide a mounting base for the reinforcing bars 4 in the outer frame member 2, or the number thereof can be significantly reduced.

In the invention according to claim 3, the concave groove 1 is provided.
The back side of 2 is used as a housing portion 16 for the head portion 15 of the mounting bolt 14, and the opening side of the concave groove 12 is used for the shaft portion 1 of the mounting bolt 14.
7 is a narrow portion 18 through which the head portion 15 cannot pass, but the mounting bolt 14 is slidably accommodated in the groove 12 with the shaft portion 17 of the mounting bolt 14 protruding from the back surface of the outer frame member 2. it can.

[0012]

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 includes an outer frame member 2 made of a relatively thin steel plate.
And a concrete 3 filled in the frame material 2 and hardened, and a mesh rebar 4 embedded in the concrete 3.

The outer frame member 2 is formed by bending a single steel plate into a predetermined shape as shown in FIG. 2 by press molding or the like, and has a bottom plate 5 having a rectangular shape in plan view and four peripheral edges of the bottom plate 5 on the front surface side ( It has a side plate 6 protruding upward (in FIG. 2). Each side plate 6 is bent substantially perpendicularly to the bottom plate 5, and the concrete 3 in the outer frame member 2 is filled to the maximum of the protruding height of each side plate 6.

The outer frame material 2 functions as a discard form when the concrete 3 cast therein is uncured, and after the cast concrete 3 is cured,
It functions as a reinforcing member for improving the tensile strength of the concrete 3 and preventing chipping of its end. In particular, when aerated concrete (ALC) is used as the concrete 3 to be filled in the outer frame material 2 for weight reduction, the aerated concrete has high water absorbency and the edges are fragile and easily chipped. It is significant to cover the concrete 3 with the outer frame material 2.

Four side plates 6 forming the peripheral edge of the outer frame member 2
Of these, a fitting protrusion 7 having a U-shaped cross section is provided along the longitudinal direction at the upper and lower central portions of the side plate 6R on the right side in the width direction, and on the other hand, a central portion on the upper and lower sides of the side plate 6L on the left side in the width direction is provided. The fitting recessed groove 8 into which the fitting protrusion 7 is fitted is extended along the longitudinal direction. Therefore, as shown in FIG. 1, by fitting the fitting protrusions 7 of the other composite panel building material 1 into the fitting recessed grooves 8 of the one composite panel building material 1, the composite panels adjacent in the width direction are fitted. The building materials 1 and 1 can be joined flush with each other.

As shown in FIG. 4, the side plates 6E at both longitudinal ends of the outer frame member 2 are formed in the same plane without the protrusions 7 and the concave grooves 8. At the projecting end (upper end in FIG. 2) of each side plate 6, an edging portion 9 projecting inside the outer frame member 2 is bent and formed. The edge of the edging portion 9 is bent substantially perpendicularly to the side plate 6, and the end portion inside the frame is bent downward toward the bottom plate 5.
0, and the free end 11 of the edging portion 9 is embedded in the concrete 3 through the hanging portion 10.

As described above, since the edging portion 9 is embedded in the concrete 3 in 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 conveyed. It is possible to prevent the free end 11 of the edging portion 3 from rolling up. Further, even if the side plate 6 is deformed in the direction away from the concrete 3 due to thermal stress or repeated stress after construction, the hanging portion 10 of the edging portion 9
Does not cause such deformation because it bites into the concrete 3, and therefore the edging portion 9 does not bulge upward as a whole.

Further, in the case of this embodiment, the end portion of the bottom plate 5, the side plate 6, the edging portion 9 and the hanging portion 10 thereof constitute a frame cross-section structure having a substantially C-shaped cross section 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 significantly improved. The mesh rebar 4 is embedded in the concrete 3 to improve its tensile strength, and is made of steel wire rods framed in a grid pattern at a constant pitch, the end of which is the lower end of the hanging part 10 (rimming). It is arranged slightly above the surface of the composite panel building material 1 by being welded to the free end 11) of the part 9.

Therefore, in this case, the hanging portion 1 of the edging portion 9
Since 0 also functions as a mounting portion for the mesh rebar 4, it is not necessary to provide a new mounting base for the mesh rebar 4 in the outer frame member 2 or the number thereof can be significantly reduced. The labor required to perform the work is reduced. As shown in FIGS. 2 and 3, a recessed groove 12 that opens downward by recessing the bottom plate 5 toward the inside of the outer frame member 2 is formed in the widthwise middle portion of the bottom plate 5. The recessed grooves 12 are formed at three positions in the center of the bottom plate 5 in the width direction and on both left and right sides, and each of the recessed grooves 12 extends across both ends in the longitudinal direction of the outer frame member 2.

Reinforcing ribs 13 bulging inward of the outer frame member 2 and extending in the width direction are formed between the concave grooves 12 in the bottom plate 5 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 used.
To prevent lateral slippage. Each of the above-mentioned recessed grooves 12 is formed in a substantially T-shape in cross section, and the back side of the recessed grooves 12 is a storage space capable of storing a head portion 15 of a mounting bolt 14 for mounting the composite panel building material 1 on a beam or the like. Part 16 and the opening side of the concave groove 12 has the mounting bolt 1
The shaft portion 17 of No. 4 is a narrow portion 18 through which the head portion 15 of the bolt 14 cannot pass.

The head portion 15 of the mounting bolt 14 is housed in the housing portion 16 of the concave groove 12 so that the shaft portion 17 of the mounting bolt 14 projects from the back surface of the outer frame member 2. The groove 12 is slidably engaged with the groove 12 along the longitudinal direction of the frame member 2. The shaft portion 1 of the mounting bolt 14
7 is inserted into a square washer 19, and this washer 1
9 is accommodated in the accommodating portion 16 together with the head portion 15 to facilitate the sliding of the mounting bolt 14 into the concave groove 12.

5 and 6 show a mounting structure when the composite panel building material 1 having the groove 12 is used as a floor material, both of which are flange portions 21 of a beam material 20 made of H-shaped steel. The longitudinal end portion of the composite panel building material 1 is placed on. Of these, in FIG. 5, the flange portion 21 of the beam member 20 is sandwiched by the mounting stays 22 that are in contact with the lower surface of the longitudinal end portion of the composite panel building material 1, and the shaft portions 17 of the mounting bolts 14 that penetrate the mounting stays 22 are attached to the shaft portions 17. The composite panel building material 1 is fixed to the beam member 20 by tightening the screwed nut 23.

On the other hand, in FIG. 6, the flange portion 2 of the beam member 20 is shown.
The nut 2 is attached to the shaft portion 17 of the mounting bolt 14 penetrating the 1 itself.
Composite panel building material 1 by screwing 3 together and tightening
Are fixed to the beam member 20. In this way, the beam member 20 of the composite panel building material 1 depends on which mounting structure is adopted.
However, in this embodiment, the mounting bolt 14 is slidably housed in the groove 12 with its shaft portion 17 protruding from the back surface of the outer frame member 2, Any mounting structure can be dealt with by simply sliding the bolt 14 along the groove 12.

Further, the concave groove 12 also functions as a reinforcing rib when viewed from the inside of the outer frame member 2, so that the bending strength in the longitudinal direction of the composite panel building material 1 is improved and the outer frame member 2 of the outer frame member 2 is improved. Since it projects to the inside, the amount of concrete 3 to be filled inside is reduced by that amount, and the weight and cost of the building material 1 can be reduced. The present invention is not limited to the above embodiment, and in particular, the edging portion 9
The shape of can be variously changed as shown in FIGS. 7 and 8, for example.

Of these, the edging portion 9 shown in FIG. 7 is curved downward toward the inside of the frame (left side in the figure), and by bending the inside of the edging portion 9 in this manner, the free end 11 is formed. Can also be embedded in concrete. Further, the edging portion 9 shown in FIG. 8 is bent so as to incline downward from the root thereof, and thus even if the base of the edging portion 9 is bent and the free end 11 thereof is embedded in concrete.
