Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a concrete panel forming method that can easily and accurately form dents at predetermined intervals on a concrete panel without damaging the surface condition, and can increase the productivity of grooved concrete panels. Regarding equipment.

[Background technology]

Conventionally, a grooved concrete panel is formed by pouring concrete into a formwork placed on a mounting table to form an uncured concrete panel A, as shown in FIG. 5, for example. By transferring a roll body having a plurality of protrusions B protruding from the circumferential surface C onto the concrete panel A in a state in which the circumferential surface C is brought into direct contact with the concrete panel A, the shape of the protrusions B is changed. It formed a groove. Therefore, the concrete panel A comes into contact with and separates from the peripheral surface C of the roll body due to its transfer, and 111
At the time of ttB, the circumferential surface C lifts the surface of the concrete panel A due to its adhesion, which has the disadvantage of deteriorating the surface condition of the concrete panel A, such as creating unevenness on the surface of the concrete panel 8.

Furthermore, in the conventional type, the groove position is limited to the formation interval of the projections B of the roll body, and the 18-shaped groove is also limited to the formation interval of the projections B of the roll body.
There are also problems in that it is difficult to form only grooves with curved surface shapes such as circular arc cycloids and involute curved surfaces.
