Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to reinforced reinforced concrete panels used in constructing walls, floors, etc. of buildings.

Conventional techniques and problems to be solved by the invention Conventionally, in concrete buildings with reinforced reinforcing bars, both sides of the reinforcing bars are surrounded by formwork made of iron plates, plywood, etc.
After filling the concrete with fresh concrete and solidifying it, the formwork is removed to form walls and floors. It takes a long time to remove the frame connecting members, which is an obstacle to shortening the construction period and reducing construction costs.In particular, when installing tiles on a concrete surface, it is necessary to attach them with adhesive on site after assimilating the concrete. Two methods are used: one method is to temporarily attach the tiles face down inside the formwork, fill it with concrete, and after the concrete solidifies, the formwork is removed. The construction method in which the concrete is pasted through construction is expensive, and the method in which the concrete is temporarily attached to the formwork not only requires the cost of removing the formwork. This had the disadvantage of prolonging the construction period as it required work to remove the formwork.

Means for Solving the Problems The concrete panel of the present invention enables a new construction method for concrete buildings that eliminates the drawbacks of the conventional construction method, and it is possible to use a new concrete construction method that eliminates the drawbacks of the conventional construction method. was embedded, and a screw hole for a nut connected to the reinforcing bar was opened on one surface.

Functions and Effects of the Invention The concrete panel of the present invention has the above-mentioned structure, and since the screw holes for the nuts connected to the reinforcing bars are opened on the - side surface, anchor bolts are inserted into these screw holes to form the corresponding formwork. By filling raw concrete between the concrete panels, or by connecting two concrete panels with a connecting member at a distance using the screw holes, filling raw concrete between them and allowing it to harden. A wall or floor, etc., is formed of reinforced reinforced concrete in which the concrete panel of the present invention is used as the surface layer and anchor bolts or connecting members are embedded in the inner layer of concrete, and the nuts are embedded in the concrete. Not only are the anchor bolts or connecting members bonded to the concrete, but they are also bonded to the reinforcing bars, allowing the anchor bolts or connecting members to be firmly bonded to the concrete to form strong walls and floors. Since it becomes the formwork for filling, at least the assembly and removal of the formwork on the side where this panel is used becomes unnecessary, making it possible to reduce construction costs and shorten the construction period. If tiles are tiled in advance, on-site work can be carried out in exactly the same way as when tiles are not tiled, which has the effect of significantly improving construction efficiency.

In addition to the construction methods described above, the concrete panel of the present invention can also be used in a construction method in which it is fixed by bolting to a steel frame using screw holes to form a wall or floor. .

EXAMPLES Hereinafter, examples of concrete panels of the present invention and examples of construction methods using the same will be described based on the accompanying drawings.

The manufacturing method of the concrete panel P1 according to an embodiment of the present invention will be explained based on FIG. Mounting plates 4 having one through hole 5 on the lower surface are welded at appropriate intervals, and a nut 6 is welded or glued to each mounting plate 4 with its screw hole 7 aligned with the through hole 5. After the structure with tape 8 pasted on the top surface of 6 and the screw holes 7 closed is horizontally housed with the mounting plate 4 in close contact with the bottom,
Fresh concrete 9 is filled in the form l, and a large number of ceramic tiles 10 are arranged on top of it with appropriate joint spacing 11 left, and then a holding plate 12 with a vibration exciter 13 attached to the top surface. When the holding plate 12 is vibrated by the vibrator 13, the raw concrete 9 is spread to every corner of the formwork l, except for the screw holes 7 of the nuts 6, which are covered by the tape 8, without any gaps. When the tile 10 is embedded in the concrete 9 to about half its thickness, the vibrator 13 is stopped, the holding plate 12 is removed, and the formwork 1 is removed after the concrete 9 has solidified after being left for a certain period of time. The reinforcing bars 2 are embedded in the solidified concrete 9 and tiles 10 are stretched on the surface of the concrete 9, and the bottom surface of the mounting plate 4 welded to the reinforcing bars 2 is exposed on the back surface and a through hole is formed there. The concrete panel P1 of this example in which the screw holes 7 of the nuts 6 are opened on the back side through the nuts 5 is obtained. Note that a concrete panel P2 without tiles 10 pasted on its surface is also manufactured by the same method.

An example of construction of a wall of a building using the concrete panels P1 and P2 of the present invention described above will be explained with reference to FIGS. 2, 3, and 4. The example in FIG. Anchor bolt a is screwed into screw hole 7 of nut 6 opened on the back side of panel P1 so that the head protrudes, and this concrete panel P1 and formwork made of steel plate or plywood are faced with reinforcing bar C in between. During this time, fresh concrete d is filled and solidified, and then the formwork is removed.

The concrete panel P1 of the present invention on which tiles 10 are pasted forms the surface layer, and the anchor bolts a protruding from the back surface are embedded in the concrete d to form a wall with a strong structure.

Next, in the construction example shown in FIG. 3, a concrete panel P1 of the present invention with tiles 10 pasted on the surface and a concrete panel P2 of the present invention with no tiles 10 pasted on the surface are placed back-to-back with an interval between them. , insert the connecting member e, which is made by bending both ends of an elongated steel plate and forming a mounting hole f in the bent part, between both panels P1.22, aligning the mounting hole f with the screw hole 7 of the nut 6, and tighten the bolt g. The concrete panels P1 and P2 of the present invention are those in which both panels P1 and P2 are joined with a space between them by screwing and tightening, and green concrete d is filled and solidified between them, and the concrete panels P1 and P2 of the present invention
A strong reinforced concrete wall is constructed in which the connecting member e, which forms the surface layer and is embedded in the concrete d, is connected to the reinforcing bars 2 and 2 on both sides of the concrete panel 1 through the mounting plate 4 and nuts 6, and the concrete panel P ,, Since P2 also serves as a formwork, there is no need to remove the formwork, and since the tiles 1O have been pasted on one side in advance, the construction period is significantly shortened.

The construction example shown in Fig. 4 is a concrete panel P of the present invention.
2 is attached to the steel frame by aligning its screw hole 7 with the installation hole k of the steel frame, and fixing it to the steel frame by passing the bolt g through the installation hole k and screwing into the screw hole 7. By attaching a gypsum board to the other side and filling the gap with insulation material, the outer wall of a building can be constructed like the well-known ALC board, and since the reinforcing bars 2 are embedded, it is extremely strong. In addition, since the bolt g is screwed into the nut 6 fixed to the reinforcing bar 2 and fixed to the reinforcing bar k, the joint strength is extremely high.
