Integrated surveying and mapping device for building construction

The utility model discloses an integrated surveying and mapping device for building construction, which belongs to the technical field of building construction, by pressing down a surveying and mapping instrument main body, when two clamping plates slide to the lower part of a positioning column, two sliding rods respectively drive the two clamping plates to be close to each other under the elastic force action of a spring I, so that the clamping plates limit a mounting cylinder; meanwhile, the bottom of the mounting cylinder is in contact with a pressing plate, namely, the surveying instrument body, the base and the erecting assembly form the surveying device which is integrally designed, when the surveying instrument body is disassembled, the surveying instrument body is pressed downwards, two clamping plates move downwards to the position below a sliding column, then the surveying instrument body is lifted upwards, and the clamping plates drive the sliding column to move upwards and make contact with a pos
