Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building panel which is embedded in a building such as a floor, a wall, a pillar or a beam of a building for heat insulation and noise reduction, and a manufacturing method thereof.

[0002]

2. Description of the Related Art A technique disclosed in Japanese Utility Model Publication No. 53-54407, for example, is known as a technique for embedding a panel for heat insulation and sound deadening in a body made of concrete such as floors, walls, beams and columns of a building. There is. This panel consists of a core plate in which a large number of dovetail grooves are alternately formed on the upper and lower surfaces, a heat insulating material inserted into each core plate, and a reinforcing bar arranged on the upper and lower surfaces of the core plate in a direction orthogonal to the dovetail groove. It is composed. This panel is surrounded by concrete and is insulated and muffled by a heat insulating material.

[0003]

However, the above panel has the following problems. 1) It is difficult to mold the core material because the dovetail grooves that are alternately continuous are formed in advance. 2) It is necessary to separately form the core material, the heat insulating material, and the reinforcing bar for reinforcing bar, and since the reinforcing bar is arranged later, there are many manufacturing processes, and workability and economic efficiency are poor. 3) The heat insulating material may be damaged when it is inserted into the dovetail groove of the core material. Therefore, the present invention provides a building panel having a small number of parts, easy molding, a shortened manufacturing process, and excellent workability, economy, and workability in which members are not damaged during molding, and a manufacturing method thereof. That is.

In order to achieve the above-mentioned object, the structure of the present invention comprises an upper braced bar which is vertically and horizontally reinforced, a lower braided bar which is also vertically and horizontally reinforced, an upper braided bar and a lower braided bar. In a building panel consisting of a plurality of connecting rebars for joining each rebar by opening an arbitrary gap between the rebars and a heat insulating material for foaming in the gaps to cover the connecting rebars, an upper rebar The lower assembled rebar is composed of a plurality of vertical rebars arranged in upper and lower two stages, and a plurality of horizontal rebars arranged in upper and lower two stages orthogonal to the respective longitudinal rebars, and further the above connection It is characterized in that the reinforcing bar is composed of a central inclined part and upper and lower vertical parts, and the upper and lower vertical parts are welded to the upper and lower two-stage vertical reinforcing bars constituting the upper and lower assembled bars, respectively. To do. In this case, it is preferable that the vertical reinforcing bars and the horizontal reinforcing bars are welded at positions where they intersect.

[0005]

[Operation] In the building panel, the upper and lower assembled reinforcing bars, the connecting reinforcing bars and the heat insulating material are integrally assembled, so the floor,
It is embedded in the concrete body such as walls and columns.In this state, the reinforcing bars and connecting reinforcing bars reinforce the concrete, and the heat insulating material blocks cold air and sound from the outside, and heat escapes from the inside to the outside. To prevent.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. The building panel of the present invention comprises an upper braced bar 1 and a longitudinally and horizontally braided bar, and a lower braided bar 2 having a vertical and horizontal bar.
2, a plurality of connecting rebars 3a for connecting each rebar by opening an arbitrary gap between the upper rebars 1 and 1 and the lower rebars 2 and 2, and the connecting rebars 3a formed by foaming in the gaps. And a heat insulating material 4 for covering the. In this case, a plurality of vertical reinforcing bars 5a, 5a, 5b, 5b in which an upper assembled reinforcing bar 1 and a lower assembled reinforcing bar 2 are arranged in two steps in the upper and lower direction and upper and lower two reinforcing bars 5a, 5a orthogonal to the vertical reinforcing bars 5a, 5a, respectively. Composed of a plurality of lateral reinforcing bars 6a, 6a, 6b, 6b arranged in steps,
Further, the connecting rebar 3a is composed of a central inclined portion 19 and upper and lower vertical portions 20 and 21, and the upper and lower vertical portions 20 and 21 are respectively formed in upper and lower two stages forming an upper assembled rebar 1 and a lower assembled rebar 2. It is welded to the longitudinal reinforcing bars 5a, 5a, 5b, 5b. Longitudinal rebars 5a, 5b and lateral rebars 6a,
It is welded at a position intersecting with 6b. The heat insulating material 4 is made of foam material such as urethane foam and styrofoam, and is used for heat insulation and noise reduction. The above building panels are unitized, as shown in FIG. 1, the floor of the building,
It is embedded in a concrete skeleton B such as a wall or a pillar. That is, when a building panel that has been unitized in advance is assembled in a formwork at the time of forming the building body, and concrete C is then placed in this formwork, the building body B is formed in a state in which the building panel is covered with the concrete C. To be done. As for the skeleton B, concrete C is reinforced by the upper and lower assembled rebars 1 and 2 and the connecting rebars 3a like a normal reinforced concrete structure, and the heat insulating material 4 blocks cold air from the outside to the inside and also from the outside to the inside. Insulates the noise and achieves heat insulation and noise reduction. In addition, a heat insulating effect can be obtained which prevents heat from escaping from the inside to the outside of the building. In the embodiment of FIG. 1, the upper assembled rebars 1 and 1 are arranged in two stages above, and the lower assembled rebars 2 and 2 are arranged in two below as well.
In this case, a single reinforcing bar composed of a central inclined portion 19 and upper and lower vertical portions 20, 21 is alternately arranged in a trapezoidal shape. In this case, the central inclined portion 19 is covered with the heat insulating material 4, and the upper and lower vertical portions 20 and 21 are joined to the vertical reinforcing bars 5a, 5a, 5b and 5b by welding or the like. The building panel of FIG. 1 is preferably used when molding a floor or wall skeleton. And when molding the structure of beams and columns, those with the same structure are molded and used,
It can be applied to all structures of buildings.

[0007]

The present invention has the following effects. 1) The building panel of the present invention is formed of only three sets of members, that is, upper and lower assembled reinforcing bars, connecting reinforcing bars, and a heat insulating material. , Excellent in economy. 2) The upper braided bar and the lower braided bar are a plurality of vertical rebars arranged in upper and lower two stages, and a plurality of horizontal rebars arranged in upper and lower two stages orthogonal to each vertical rebar. Since it is composed of, the strength is great. 3) Since the heat insulating material is provided, the heat insulating effect and the sound deadening effect in the reinforced concrete structure can be achieved.
