Building concrete drilling and coring device

The utility model relates to a building concrete drilling and coring device, belongs to the technical field of concrete coring, and solves the technical problem that a concrete core is inconvenient to take out after concrete drilling. The concrete drilling and coring device comprises a support, a coring barrel, a driving part and a clamping part, one end of the coring barrel is rotationally installed on the support, and the support pushes the coring barrel to move in the axial direction of the coring barrel so as to drill concrete; the driving piece is mounted in the coring cylinder and is mounted at one end, close to the bracket, of the coring cylinder; the clamping piece is installed on the driving piece in a sliding mode and located in the coring barrel, and the driving piece is used for driving the clamping piece to move so as to clamp the concrete core. Therefore, when the building concrete drilling and coring device is used for coring concrete, the concrete core body can be taken out by clamping the con
