Water heating cloth positioning mechanism for building construction

The utility model belongs to the technical field of buildings, and particularly relates to a water heating cloth positioning mechanism for building construction, which comprises a first horizontal plate, a connecting hole is formed in the top of the first horizontal plate, a positioning ram is mounted at the top of the first horizontal plate, a motor is arranged on one side of the positioning ram,and a transmission shaft is arranged at the output end of the motor. A plurality of connecting holes are formed in the surfaces of the first horizontal plate and the second horizontal plate; a corresponding number of pins are matched through the connecting holes to fix the positioning ram; construction process, the side edges of the positioning ram can be overlapped with the wall edge; the arrangement position is observed, so that the positioning deviation is reduced, secondary rework is prevented, the installation and construction period is shortened, the extension positioning pipe can be installed and detached thro
