Hole centre rapid marking-positioning device and hole centre bias check method

The invention discloses a hole centre rapid marking-positioning device and a hole centre bias check method, and relates to the technical field of hole centre marking. The hole centre rapid marking-positioning device comprises polyurethane round rods capable of inserting in holes, wherein the outer diameter of each polyurethane round rod is greater than the diameter of the corresponding hole; grooves are formed in the sidewall of each polyurethane round rod; and cross lines with an intersection point which passes through the circle centre of the upper end surface are engraved on the upper end surface of each polyurethane round rod. The invention further discloses a hole centre bias check method, and said hole centre check device is used for check. The hole centre rapid marking-positioning device and the hole centre bias check method, which are disclosed by the invention, are capable of realizing rapid marking-positioning for hole centres, capable of conveniently and rapidly detecting whether the hole centres are biased or not, high in detection accuracy, and suitable for being applied in various construction fields.
