Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a corner corner panel made of concrete for an outer wall in which an insert nut is embedded.

(Prior Art) A conventional concrete corner corner panel made of concrete is shown in FIG.

The nut main body a had a cylindrical outer shape, and had a flange b at the base end. Reference numeral c is an anchor plate, and the nut body a is inserted into a through hole d formed in the anchor plate c, and the flange b is joined to the anchor plate c to form the insert nut e. By embedding the insert nut e inside the panel body f made of concrete, a corner corner panel is formed.

The panel body f is bent at a right angle so as to be along the projecting corner. In the panel main body f, the mesh-shaped reinforcing bar g bent at a right angle like the panel main body f is deformed reinforcing bar h.
It is supported and arranged by. The position of the insert nut e is fixed by binding the anchor plate c to the deformed bar h or the mesh-shaped bar g with a string or the like.

Reference numeral i in the figure is a mounting bracket for mounting a concrete corner corner panel to a corner post or a frame assembly (not shown), j
Is a mounting bolt, and k is a washer. Further, 1 is the target bottom of the panel body f.

(Problems to be solved by the invention) In the corner corner panel made of concrete thus formed, the nut body a and the anchor plate c are often not sufficiently coupled, and moreover, the outer shape of the nut body a is a cylinder. Therefore, when the mounting bolt j is tightened, there is a problem that the nut body a rotates together with the mounting bolt j and a sufficient tightening force cannot be obtained. Further, in order to solve such a problem, it is conceivable to increase the total length of the nut main body a, but in this case, the mesh-shaped reinforcing bar g is shifted from the central portion of the panel main body f to the outer surface side. , The distance w between the mesh-shaped reinforcing bar g and the outer surface of the panel body f becomes shorter. As a result, the covering thickness of the mesh-shaped reinforcing bar g is reduced, and the strength of the corner corner panel made of concrete is reduced.

(Means for Solving the Problems) A concrete corner corner panel made of concrete of the outer wall of the present invention is provided in a panel body bent at a right angle along the corner of the corner.
A corner corner panel made of concrete in which reinforcing bars are arranged along the panel body, and the outer end of the nut body formed into a prism such as a hexagonal shape is passed through the through hole provided in the anchor plate. The insert nut, which is made upright and is caulked at the base end of the nut body that penetrates through this through hole and is integrally fixed to the nut body and the anchor plate, is used to reinforce the anchor plate at the center of the panel body. It is fastened and is embedded in the panel body so that the tip end surface of the nut body is exposed from the side surface of the concrete panel body.

(Operation) Since the insert nut is securely connected by crimping the nut body and the anchor plate, there is no problem that the anchor plate and the nut body separate and rotate, and the concrete corner corner panel is surely installed in the building. Mounted on the framework. Since the nut body is securely fixed to the anchor plate in this manner, the reinforcing bar can be located in the center of the panel body to form a concrete panel having high strength.

(Embodiment) FIG. 1 is a cross-sectional view of an outer corner corner panel of an outer wall according to the present invention, FIG. 2 is a plan view of an insert nut, and FIGS. Shows the procedure for creating.

The outer corner corner panel of the present invention has an insert nut 3 integrally fixed to an anchor plate 2 at the base end portion of a nut body 1 formed into a prism such as a hexagonal shape, a pentagonal shape, and a square shape. Is embedded in the inside of the panel body 4 so that the front end surface of the is exposed from the side surface of the concrete panel body. The panel body 4 is bent at a right angle so as to be along the projecting corner.

The insert nut 3 is shown in FIGS. 3 (a), (b), (c).
It is created by the procedure shown in. That is, the protrusion 5 is provided in the base end portion of the nut body 1 formed into a prism, and the protrusion 5 is passed through the through hole 6 formed in the anchor plate 2 [see FIG. 3 (a)]. The nut body 1 is set upright on the anchor plate 2 [see FIG. 3 (b)]. The through hole 6 is formed as a tapered hole that widens downward. In this state, the protrusion 5 protruding downward from the lower surface of the anchor plate 2 is squeezed so as to be integrated with each other. The protrusions 5 squeezed and squeezed are filled in the tapered surfaces of the through holes 6 formed in the anchor plate 2, so that the nut body 1 is completely and integrally integrated with the anchor plate 2.

The insert nut 3 thus constructed is attached to the panel body 4
It is buried inside. The reinforcing bars arranged in the center of the concrete panel body 4 are composed of mesh-shaped reinforcing bars 7 and deformed reinforcing bars 8. Like the panel body 4, the mesh-shaped reinforcing bar 7 is bent at a substantially right angle, and
The deformed rebar 8 is supported in the central portion of the.
The anchor plate 2 of the insert nut 3 is fixed to the mesh-shaped reinforcing bar 7 or the deformed reinforcing bar 8 with a wire or a stopper. Concrete is filled in a mold (not shown) set in this state and cured to manufacture a corner projection panel for the outer wall of the concrete. Reference numeral 9 in the figure is the bottom of the joint.

(Effect of the invention) Since the nut body of the insert nut is formed into a hexagonal prism or the like and the nut body is completely integrated and attached to the anchor plate by the caulking means, the bolt is screwed in and tightened tightly. However, there is no problem that the insert nut rotates inside the panel body, or that only the nut body comes out of the panel body and interferes with the mounting of the concrete corner corner panel of the outer wall to the frame or the like.

Since the insert nut is thus completely fixed in the panel body, the total length of the nut body may be short. Therefore, the reinforcing bar for fixing the anchor plate of the insert nut can be arranged in the central portion of the panel body. Therefore, the cover thickness of the rebar is large,
It can be used as a corner corner panel made of concrete with a strong outer wall.
