Building steel structure deformation detection device

The invention relates to a building steel structure deformation detection device, and relates to the field of engineering detection, the building steel structure deformation detection device comprises a base, a detection table, a laser emitter, a laser receiver and an alarm, the base is used for advancing on the ground through a walking assembly, and the base is provided with a height adjusting assembly for driving the detection table to ascend and descend; the laser transmitter and the laser receiver are oppositely arranged on the detection table, a distance adjusting assembly used for adjusting the distance between the laser transmitter and the laser receiver is arranged on the detection table, the alarm is arranged on the detection table, and communication connection is established between the alarm and the laser receiver. The device has the effect of replacing a worker to climb to a high place to detect the deformation of the steel beam, time and labor are saved, and the detection efficiency is high. 本申请涉
