Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a PC panel used for an outer wall of a building and a method for manufacturing the PC panel.

[0002]

2. Description of the Related Art Conventionally, in a method of manufacturing a PC panel, a metal plate-like member is assembled to form a frame, and a concrete member is placed in the frame to cure and cure it. At that time, oil or the like is applied to the concrete member placement surface of the metal plate-shaped member (sometimes a veneer plate is used) so that the mold can be easily removed after the concrete member is hardened.

A PC whose surface is covered with tiles
In the case of a panel, tiles are laid on the bottom surface of a bottomed formwork to perform joint treatment, and then concrete members are cast through mortar or the like to form the concrete.

However, in the joints of the tiles that make up the surface of the PC panel, the jointing material filled in the joints during the joint treatment may overflow and adhere to the tile surface, impairing the makeup of the tile surface. Therefore, it is necessary to clean the tile surface, and there is a problem in the manufacturing method peculiar to the wet method that requires a lot of labor and time for the tile cleaning work after the mold is removed.

For this reason, P which has been made up with conventional tiles
Since the C panel may have residual joint material that has fallen off, there is a problem in the cosmetic condition of the surface, and no consideration is given to the heat insulating property.

[0006]

The problem to be solved is that the makeup on the surface of the PC panel has a variation in makeup due to the structure requiring a joint material.
It is a point that we can not expect heat insulation at all, and there is a problem in the manufacturing method that unavoidable joint work that requires a lot of labor and labor and washing off the joint material that adheres to the tile and damages the makeup. There is.

[0007]

In order to achieve the above-mentioned object, the present invention provides a PC panel having a three-layer structure consisting of a tile panel as a surface layer, a heat insulating member as an intermediate layer, and a concrete member as a back surface layer. A connection portion with a PC panel connected to the end portion is formed along the longitudinal direction at the end portion, and the tile panel integrally engages the tile on the front surface side of the panel by a locking element by an appropriate dry method. It is characterized by being worn.

Further, in the PC panel of the present invention, the connecting portions at the upper and lower ends may be formed by the form material itself used for placing the concrete member. The tile is appropriately selected from known members including ceramics, the panel is a hollow or solid extruded member, and the heat insulating member is polyurethane foam.

As a means for manufacturing the above PC panel, a tile panel in which tiles are attached to the panel surface is laid so that the surface side faces downward, and one end of a rod-shaped member is embedded at an appropriate position on the back surface of the tile panel. Stand upright and arrange the formwork along the left and right side surfaces of this tile panel,
A first step of arranging and framing a form material capable of forming a connecting portion at the upper and lower edges thereof, a heat insulating member is arranged on the back surface of the tile panel in the form material via a rod-shaped member. And a second step of placing a concrete member on the heat insulating member and burying the upper end of the rod-shaped member in the concrete member,
After the concrete member is cured and hardened, it is manufactured through a third step of removing at least the right and left side surface side mold material of the tile panel in the mold.

In the manufacturing method of the present invention,
The panel may be a hollow panel, or the concrete member may be placed by forming irregularities on the surface of the heat insulating member on the concrete member side before placing the concrete member.

[0011]

In the PC panel, the tile panel surface is fixed to the panel surface by the dry method, and the tiles are integrated to make up the surface. Excellent and high commercial value. Moreover, since the heat insulating member as the intermediate layer is interposed between the tile panel of the front surface layer and the concrete member of the back surface layer, the external heat insulating property is excellent.

Then, the PC panel is laid so that a tile panel in which tiles are attached to the panel surface faces downward, and one end of a rod-shaped member is embedded in an appropriate position on the back surface of the tile panel to stand upright. After arranging a frame material on the left and right side surfaces of this tile panel and a frame material of a mode capable of forming a connection portion at the upper and lower end edges thereof, respectively After arranging the heat insulating member through the rod-shaped member on the back surface of the tile panel and placing a concrete member on the heat insulating member, the upper end of the rod-shaped member is embedded in the concrete member, and after the concrete member is cured and hardened. ,
Since it is manufactured by removing the mold material on at least the left and right side surfaces of the tile panel in the mold, joint work that requires a great deal of labor and labor and work for cleaning and removing the joint material are unnecessary, and workability is improved. Can be significantly improved.

In the tile panel, the tile is previously attached to the panel by a locking element by an appropriate dry method, so that the work efficiency is high and the tile panel can be easily manufactured.

Further, since the tile panel is utilized as the bottom of the mold material, the amount of members required for manufacturing the mold can be reduced. Further, the work of removing the form material after the curing and hardening of the concrete member can be completed only by removing the form material on the left and right side surfaces of the panel.

By making the panel of the tile panel a hollow panel, the weight of the entire PC panel can be reduced, the handling during manufacturing can be facilitated, and the work load can be reduced.

Since the concavo-convex portion is formed on the surface portion of the heat insulating member on the concrete member side and the concrete member is placed therein, the joint strength between the heat insulating member and the concrete member can be increased to manufacture.
