Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a concrete panel that is attached to the outer wall of a building.

(Prior Art) In conventional concrete panels, reinforcing bars arranged in advance during manufacture were not securely fixed.

(Problems to be solved by this invention) Therefore, there were some problems, such as the reinforcing bars tending to shift during concrete pouring, and it was difficult to manufacture products with high precision.

This idea was devised in view of the above circumstances,
The purpose of the present invention is to provide a concrete panel that has high precision, strength, and is easy to attach to a building frame.

(Means for solving the problem) The configuration that is the gist of this invention is that a reinforcing frame made of shaped steel is attached around the periphery, and this reinforcing frame is formed so as to protrude from the surface of the concrete plate toward the back side. It is characterized in that the reinforcing bars buried in the concrete are fixed by a reinforcing frame.

(Example) The following description will be made based on the illustrated embodiment.

1 shows the panel body 1 of the concrete panel of this invention, and 2 shows the concrete plate portion. Reinforcing bars 3 on concrete plate part 2
is buried there. A reinforcing frame 4 is attached around the four peripheries of this concrete plate portion 2.

The reinforcing frame 4 is made of groove-shaped steel, with one side flange 4a buried in the middle of the side edge 2a of the concrete plate section 2, and attached so that a part of the inner surface of the web 4b is attached to the side edge 2a. be. The other side flange 4a and the remaining portions of the web 4b are formed to protrude in an L-shaped cross section from the concrete plate surface toward the back side. Further, the end portions of reinforcing bars 3 buried inside the concrete plate portion 2 are fixed to a reinforcing frame 4 to form the panel body 1.

As shown in FIG. 1, frame mounting plates 5 are fixed to the left and right corners of the upper end of the panel body 1, respectively. This frame mounting plate 5 is formed by bending the upper end of an elongated rectangular plate into a downward hook shape, and forming a substantially inverted L shape with the bent portion serving as a mounting portion 5a. It is provided with a U-shaped mounting notch 5b that opens at the tip, and the mounting portion 5a is fixed to the base portion 5c in a state protruding from the reinforcing frame 4 of the panel body 1 toward the back side.

Further, to the reinforcing frame 4 attached to the lower end side edge of the panel body 1, frame mounting plates 6 are fixed to the left and right sides of the intermediate portion, respectively. This frame mounting plate 6 is provided with a U-shaped mounting notch 6a at the center of the upper edge of the rectangular flat plate.
It is attached to the reinforcing frame 4 with a facing upward.

FIG. 2 shows a frame mounting plate 7 of another embodiment attached to the left and right upper ends of the panel body 1. This body mounting plate 7 has a middle part formed diagonally from the lower part, a vertical part at the top, and the upper end is bent into a hook shape so that the tip faces downward, and the bent part is attached to the mounting part 7a. This mounting part 7
A panel mounting notch 7b is provided at the tip of panel a, and it is mounted diagonally across the reinforcing frames 4, 4 mounted on the upper edge of the panel main body 1 and the left and right side edges, and the mounting portion 7a is attached to the reinforcing frame 4. It is fixed in a protruding state toward the back side.

When attaching the concrete panel of this invention with the above configuration to the building frame, the first step is to
As shown in Figure 2, on the frame made of H-beam steel,
Rails 10 for panel mounting are fixed in advance to the flange portions of the lower beams 8 and 9. This rail 10 is made of an angle material, and the upper flange portion thereof has U-shaped panel mounting notches 10a at required locations. The upper and lower beam members 8 and 9 are fixed along the outer edges of the upper surfaces of the upper flanges 8a and 9a so that the upper flanges 10a of the rails 10 face inward. Also, the rail 10 fixed to the lower beam 9
There is a notch 11a for panel mounting on the upper edge of the angle.
A panel lower mounting plate 11 provided with a panel is attached in advance.

For mounting the panel, the upper frame mounting plate 5
is hung on the upper panel mounting rail 10, and the mounting notch 5b is connected to the panel mounting notch 10 of the rail 10.
a, and tighten with an outer wall fixing bolt 12 with a washer fixed to the lower end. Next, at the lower end of the panel, the mounting notch 6a of the lower frame mounting plate 6 is aligned with the panel mounting notch 11a of the panel lower mounting plate 11 of the lower panel mounting rail 10 portion, and tightened with the bolt 13. It is then attached to the body.

In addition, especially when installing under a balcony, the panel mounting rail 10 as shown in FIG.
The upper beam 8 is fixed to the upper surface of the lower flange 8a, and the lower beam 9 is fixed to the upper surface of the upper flange 9a. Then, a concrete panel is attached to which a frame mounting plate 7 formed diagonally is fixed to the upper end, and the frame mounting plate 7 is hung from a rail 10 fixed to an upper beam 8, and the mounting notch 7b is fixed. It is aligned with the panel mounting notch 10a of the rail 10 and tightened with the outer wall bolts 12. Next, at the lower end of the panel, align the mounting notch 6a of the lower frame mounting plate 6 with the panel mounting notch 11a of the panel lower mounting plate 11,
It is fastened with bolts 13 and attached to the body.

(Effects of the invention) Since this invention consists of the above configuration, it has the following effects.

(1) During manufacturing, there is no risk of reinforcing bars shifting when concrete is poured, and the reinforcing frame has the effect of a formwork, making it possible to manufacture panels with high precision.

(2) Sufficient strength against external forces such as wind pressure and earthquakes.

(3) Since the reinforcing frame is installed so as to protrude toward the back side, a gap is formed between the concrete plates, so it is difficult to insert your hands into this gap when attaching it to the frame. It is easy to work and can be expected to improve work efficiency.

(4) A hook-shaped upper frame mounting plate is fixed along the upper edge of the back side of the reinforcing frame, protruding from the reinforcing frame toward the back side, and this upper mounting plate portion is attached to the upper beam of the frame. The panel is designed so that it can be hung while holding the rail part, so when installing the panel on the structure, hang the panel from a position where it can be easily installed, and then slide it on the rail and place it in the designated position. This allows for good work efficiency and smooth positioning.Moreover, the upper frame mounting plate is designed not only to be hung, but also to be hung while holding the rail. The work can be carried out safely and reliably without fear of the panels shifting, shaking or falling during work, and the panels are securely fixed even after installation.

(5) Both the upper and lower body mounting plates have mounting notches that open at the tips, so external wall fixing bolts can be inserted into the mounting notches with nuts attached in advance, and tightened. Anyone can easily and quickly install it without requiring any skill.
