[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carbon fiber reinforced concrete outer wall panel, and more particularly, to a structure in which a main body panel and a reinforcing steel member are structurally integrated via stud bolts with heads. The present invention relates to a carbon fiber reinforced concrete panel having improved strength and weight.

[0002]

2. Description of the Related Art Carbon fiber reinforced concrete (hereinafter referred to as CF)
RC) is widely used as an outer wall panel for high-rise buildings because of its light weight and high strength.

[0003]

However, in the case of the CFRC panel alone, it was necessary to form the CFRC panel to a certain thickness in order to secure the strength, so that the weight and weight could not be reduced sufficiently. or,
In the conventional method of joining a reinforcing steel member with a bolt to an insert nut (mounting hardware) embedded in a main body panel rib portion, structurally sufficient integration between the main body panel and the reinforcing steel member (hereinafter referred to as synthetic) Effect) was not obtained. Therefore, there is a problem that the steel member bears all the strength burden, and the main body panel must adopt a design method that does not contribute to the strength at all, and the excellent bending strength characteristics of CFRC cannot be utilized structurally.

[0004]

Means for Solving the Problems The inventors of the present invention have made intensive studies and conducted various studies in order to solve such a problem. A stud bolt with a head welded to a reinforcing steel member was embedded at the time of molding to form a main body panel. By unifying,
The inventors have found that a high-strength panel utilizing the high flexural strength characteristics of CFRC can be obtained even if it is thinner while retaining the synthetic effect.

[0005] That is, an object of the present invention is to provide a lightweight CFRC outer wall panel which can make use of the strength of carbon fiber as a reinforcing material of CFRC. A stud bolt with a head is welded to an appropriate portion of the steel frame member in an outer wall panel on which a reinforcing steel frame member is laminated along or around a rib portion of a carbon fiber reinforced concrete panel having a rib having a thick structure. The stud bolt is buried in the carbon fiber reinforced concrete panel, and is easily achieved by the carbon fiber reinforced concrete outer wall panel in which the panel body and the steel frame member are structurally integrated.

Hereinafter, the present invention will be described in more detail. One example of the CFRC exterior wall panel of the present invention is shown in FIGS. The CFRC outer wall panel main body 1 to be used in the present invention only needs to have a rib 2 having a thick structure in a peripheral portion, and the rib portion 2 may be provided at a central portion as needed.

The thickness of the outer wall panel general section 1 is usually 50 to 50.
The thickness of the rib portion 2 is, for example, about 1.2 to 4 times the thickness of the panel general portion 1. In the present invention, a stud bolt 4 with a head welded to a reinforcing steel member 3 is buried in the rib portion 2, and the CFRC main body panel 1 and the reinforcing steel member 3 are structurally integrated. The reinforcing steel member 3 is not particularly limited as long as it has a general shape as a normal steel member. Specifically, a U-shape, an H-shape, an I-shape,
A mouth-shaped member can be used. The stud bolt 4 with the head is joined to the reinforcing steel member 3 at the center of the steel flange portion 5 regardless of the shape of the steel member. The bottom portion is firmly joined by stud welding (for example, a cycle arc method, an FS cartridge method). The method of embedding the welded head stud bolt 4 part in the CFRC main body panel 1 is as follows.
It is set at the panel rib portion 2 or at a peripheral position as shown in FIG. 2 if necessary, and embedded by a method of casting a CFRC that has not been solidified yet has been kneaded with a necessary and appropriate compounding and kneading formula. Casting of CFRC is usually a rod-shaped vibrator,
This is performed using a table vibrator or a high-frequency vibrator. After the CFRC is cast, curing is usually performed all day and night, and if necessary, steam curing is performed.

As a result, an integrated product of the CFRC main body panel 1 and the reinforcing steel member 3 can be manufactured. The embedded length of the headed stud bolt 4 is the thickness of the panel rib 2 or C
Normally 40 to 90 for 1 thickness of FRC panel general part
(%) Length. The welding joint of the headed stud bolt 4 to the reinforcing steel member 3 is usually 200 to 400 (m).
m) Perform at pitch and change pitch length as needed.

[0009] A method of attaching the integrated outer wall panel to a building (projectile) is to attach a metal fitting (fastener) to the building to the reinforcing steel member 3 by welding or bolting at least at four or more places. It can be usually carried out by a method of attaching to a fitting (fastener) for attaching an outer wall panel to a building projectile (column or beam) by bolting.

[0010]

According to the present invention, since the main body panel and the reinforcing steel frame are structurally integrated, the strength of the CFRC itself can be used, so that the weight and strength can be easily reduced.
