[Detailed description of the invention]

[0001]

[Industrial applications]

 This invention relates to a perforated reinforced concrete wall material.

[0002]

[Prior art]

 Concrete wall materials have a wide range of uses, from blind walls such as stairs to retaining walls.

[0003]

[Problems to be solved by the device]

 However, in the concrete wall material, reinforcing bars are embedded to maintain its strength. Therefore, it was difficult to change the appearance of the building, and it often formed a closed space. An object of this invention is to provide a perforated reinforced concrete wall material that can maintain its strength while changing its appearance.

[0004]

[Means for Solving the Problems]

 A first invention relates to a perforated reinforced concrete wall material, in which circular or polygonal members formed of iron bars are opposed to each other, and ring-shaped reinforcing bars connected by connecting members are connected in multiple directions, and the It is characterized in that it is embedded in a wall material made of steel and a through hole is formed in a portion of the wall material located inside the ring-shaped reinforcing bar. According to a second invention, in the first invention, the ring-shaped reinforcing bar comprises a pair of opposed polygonal members and a connecting member for connecting the polygonal members, and the ring-shaped reinforcing bars are connected in a honeycomb structure. It is characterized in that, among the sides of a certain ring-shaped reinforcing bar and the ring-shaped reinforcing bar adjacent thereto, the adjacent sides are made common to each other. The third invention is characterized in that, in the first and second inventions, the through-hole has its both opening edges curvedly continuous with the surface of the concrete wall material.

[Embodiment of the invention]

 1 and 2 show a first embodiment of the present invention. As shown in FIG. 1, a circular member 1 is formed of an iron rod, and a pair of circular members 1 are opposed to each other and connected by a connecting member 2. Here, a corrugated iron bar is used as the connecting member 2, and the vertices of the corrugation are connected to the circular member 1 by welding. A pair of these circular members 1 facing each other and a connecting member 2 connecting them together form a ring-shaped reinforcing bar, and they are adjacent to each other, and their contact portions are connected in a row by welding. Further, the ring-shaped reinforcing bar groups A and the ring-shaped reinforcing bar groups B and C, which are also connected in the same row, are arranged out of phase with each other above and below the ring-shaped reinforcing bar group A connected in one row. The contact portion with is connected by welding.

When the ring-shaped reinforcing bars are connected in multiple directions in this way, they are embedded in the concrete wall material 3. Further, as shown in FIG. 2, through holes 4 are formed in the concrete wall material 3 at the portions located inside the ring-shaped reinforcing bar. Then, as shown in FIG. 2 (b), these through-holes 4 smoothly expand in diameter toward both opening ends, and both opening edges are curved on the surface of the concrete wall material 3. Are continuous.

According to the first embodiment, since the through hole 4 is formed in the concrete wall material 3, the appearance can be changed. Then, by using this concrete wall material 3, it is possible to form an open space, which is optimal for installation in a place where people gather, for example. Moreover, since both opening edges of these through holes 4 are curvilinearly continuous with the surface of the concrete wall material 3, it is possible to give a soft and gentle feeling in the cold impression of concrete. . Also, since the ring-shaped reinforcing bars are connected and embedded, it is possible to maintain the same strength as conventional concrete wall materials. Therefore, the length of this wall material can be increased, and the wall material can be installed regardless of its use or place.

In the second embodiment shown in FIG. 3, the circular member 1 is simply changed to a hexagonal member 5, and the same components as those in the first embodiment are designated by the same reference numerals and detailed description thereof will be given. The description is omitted. As shown in FIG. 3, a hexagonal member 5 is formed of an iron rod, and a pair of hexagonal members 5 are opposed to each other and connected by a connecting member 2. In this second embodiment, the connecting member 2 is composed of a rod member 6 connecting the vertices of the hexagonal member 5 and a corrugated member 7 connecting the sides of the hexagonal member 5. A pair of hexagonal members 5 facing each other and a connecting member 2 connecting them together form a ring-shaped reinforcing bar, which is connected in multiple directions in a honeycomb structure. At this time, among the sides of a certain ring-shaped reinforcing bar and the ring-shaped reinforcing bar adjacent to it, the adjacent sides are made common to each other.

When the ring-shaped reinforcing bars are connected in multiple directions in this manner, they are embedded in the concrete wall material 3. Then, forming the through holes 4 in the portions of the concrete wall material 3 located inside the ring-shaped reinforcing bar is the same as in the first embodiment. In the second embodiment, in addition to the function and effect of the first embodiment, the honeycomb structure is adopted, so that higher strength can be maintained. Moreover, among the sides of a certain ring-shaped reinforcing bar and the ring-shaped reinforcing bar adjacent to it, the adjacent sides are made common to each other, so that the cost can be reduced and the weight can be reduced.

Although the hexagonal member 5 is used in the second embodiment, other polygonal members may be used, of course. When a polygonal member is used, the honeycomb structure is adopted as in the second embodiment, and among the sides of a ring-shaped reinforcing bar and a ring-shaped reinforcing bar adjacent thereto, adjacent sides are made common to each other. Ideally, this is done, but of course the edges may be welded together and connected.

[0011]

[Effect of the invention]

 According to the first invention, since the through hole is formed in the concrete wall material, the appearance can be changed. If this concrete wall material is used, an open space can be formed, which is optimal for installation in a place where people gather, for example. Also, since the ring-shaped reinforcing bars are connected and embedded, it is possible to maintain the same strength as conventional concrete wall materials. Therefore, the length of this wall material can be increased, and the wall material can be installed regardless of its use or place.

According to the second invention, since the honeycomb structure is adopted in the first invention, higher strength can be maintained. Moreover, among the sides of a certain ring-shaped reinforcing bar and the ring-shaped reinforcing bar adjacent thereto, the adjacent sides are made common to each other, so that the cost can be reduced and the weight can be reduced. According to the third invention, in the first and second inventions, since both opening edges of the through hole are curvedly continuous with the surface of the concrete wall material, it is possible to avoid the cold impression of concrete. It can give you a soft, gentle feeling.
