In addition, there is a concern that electrolytic corrosion may occur between carbon fiber and steel in the electrolytic solution, and all myocardium to be buried in CFRC must be made of stainless steel. Could not be measured.

As a result of studying to obtain a low-cost, high-strength CFRC exterior wall panel, the flat part was molded with CFRC, and the ribs were molded with ordinary concrete or mortar. The present inventors have found that a low-cost carbon fiber reinforced concrete outer wall panel can be obtained, and arrived at the present invention.

容易に達成される。以下本考案を詳細に説明する。That is, an object of the present invention is to provide a conventional CFRC
CFR that has the same strength as the outer wall panel and is low cost
An object of the present invention is to provide a concrete outer wall panel comprising a flat plate portion and a rib portion protruding from the surface thereof, wherein the flat plate portion is obtained by kneading carbon fiber and concrete. (Hereinafter referred to as CFRC) and the rib portions are formed of non-fiber-reinforced concrete or mortar. Hereinafter, the present invention will be described in detail.

十分でありコストアップにはならない。For the ribs formed of non-fiber reinforced concrete or mortar used in the present invention, concrete or mortar that is usually used can be used, but only a small amount that does not substantially function as reinforcement. May be contained. The concrete outer wall panel of the present invention is composed of the above-mentioned flat plate portion and the rib portion. Generally, the flat plate portion having a large generated stress uses CFRC, and the rib portion where the stress is smaller than the flat plate portion is filled with ordinary concrete or mortar. However, in terms of strength, by using the myocardium to bear the strength, the strength is equivalent to that of the conventional CFRC panel, and the cost is low. The use of concrete or mortar eliminates the need to use stainless steel for the myocardium because there is no concern about electrolytic corrosion and conventional CFR
CFRC panels can be manufactured at lower cost than C panels.
In addition, the amount of myocardium for providing strength at the rib portion is a minimum amount required for manufacturing at the time of panel molding (similar to conventional CFRC), and does not increase the cost.

る。Hereinafter, an example of a method for forming a CFRC plate according to this utility model will be described. First, a guard mesh bar 4 (for example, made of 4φ- ＠ 100 stainless steel) is set near the center of the cross section of the flat plate portion 2, and then a reinforcing bar 5 (for example, 2-D10) is set on the mesh bar 4 and the rib portion 3. , SD3
The stirrups 6 (for example, 4φ ＠ 200 pitch, made of stainless steel) are arranged around the 0). In this case, the sizes and pitches of the mesh bars 4, the reinforcing bars 5, and the stirrups 6 are determined by strength calculation depending on the height shape of the building to which the panel is applied, the location conditions, and the size and shape of the panel. The size and pitch of the mesh streaks 4 are φ = 4-9
(Mm) Pitch ＠ = 100 to 200 (mm) Arranged on the entire flat plate part, reinforcing bar 5 is round steel or deformed steel bar with diameter φ = 9 to 16, and all ribs per rib are 2 to 4 The ribs 6 have a diameter of φ3 to 9 (mm) and are equally spaced over the entire longitudinal direction of the ribs.
(Mm). After the above-described reinforcing arrangement is completed, the uncured CFRC kneaded with a necessary and appropriate mixing and kneading formula is poured into the flat plate portion 2 and sufficiently cast using a rod-shaped vibrator, a high-frequency vibrator or the like. After the completion of the CFRC casting and before the hardening, the ribs 2 are filled with non-fiber reinforced concrete or mortar. The joint between the CFRC and the concrete or mortar to be laminated is structurally completely integrated by the stirrups 6 with the hardening of the cement. After the CFRC is placed, the curing is usually carried out naturally throughout the day and night and, if necessary, the steam curing. Thereby, a carbon fiber reinforced concrete outer wall panel can be manufactured.

る。The outer panel is attached to a building (projectile) in the same manner as a conventional concrete panel, with the mounting hardware (fastener) and the building projectile (column, beam) embedded in the panel first. The outer wall panel mounting hardware (fastener) that has been bonded is usually mounted by bolting. In order to confirm the effect of the present invention, a carbon fiber reinforced concrete laminated outer wall panel of the same type as that of FIG. 1 was manufactured, and a bending test was performed on a laminated portion of the rib and the flat plate, which is a problem in strength, in a straightened state.
