関するものである。Detailed Description of the Invention (Field of Industrial Application) The present invention relates to the improvement of precast concrete plates (hereinafter referred to as PC plates), and particularly relates to the improvement of precast concrete plates (hereinafter referred to as PC plates). The conventional PC reinforcement is constructed from strip-shaped iron plates having a width in the thickness direction of the PC board, so that it can support the PC board in a distributed manner, and also support it in the thickness direction of the board, and has high strength against bending of the PC board. This is related to a PC board.

願昭６１−８０２１８号に係るＰＣ筋をハニカム状に配
設したプレキャストコンクリート板を出願した。(Prior art) Conventionally, PC boards have been mainly used for concrete boards for partitions or external walls, and reinforcing bars in the form of a lattice that intersect vertically and horizontally are embedded inside the PC board. It has the strength to support the load that acts on the PC board, and the reinforcing bars of the PC board are laid out in a planar manner, crossing the board in the vertical and horizontal directions. Dispersion was only in two directions, and the reinforcing bars placed vertically and horizontally were welded at points at intersections, so there was a problem in terms of strength against bending.In order to increase the strength, the reinforcing bars had to be made thicker. ,
It is necessary to increase the thickness of the PC board, which requires a large amount of raw materials, making it expensive, and increases the weight, making it difficult to handle.
Because of problems such as reduced assemblability, the applicant filed an application for a precast concrete plate having PC bars arranged in a honeycomb shape according to Japanese Patent Application No. 80218/1983.

。(Problem to be solved by the invention) However, the above precast concrete plate with honeycomb-shaped PC bars disperses and supports the load applied to the plate surface in three directions, and has improved strength compared to the conventional one. Since the reinforcing bars are arranged in a planar manner, reinforcement in the thickness direction of the PC board is insufficient, and it has been particularly desired to increase the strength against bending.
