Embodiment Construction

[0009] The present invention will be further described below in conjunction with accompanying drawing.

[0010] see figure 1 , the figure shows an easy-to-operate measurement method for the deformation of steel structures, including a deformable object M and three radio wave transmitters F1-F3, wherein the three radio wave transmitters F1-F3 are placed in parallel according to the axial direction In the same horizontal plane directly in front of the deformed object.

[0011] The three radio wave transmitters F1-F3 transmit radio waves to the deformable object synchronously, and the first radio wave transmitter F1 waits to receive the radio wave emitted by the first radio wave transmitter F1 reflected by the deformable object, and records the first radio wave transmitter F1 from transmitting radio wave to receiving the time T1 of the radio wave emitted by the first radio wave transmitter F1 of reflection, the second radio wave transmitter F2 waits to receive the radio wave emi...

Abstract

The invention discloses a method which is used for measuring steel structure deformation and easy to operate. The method comprises a deformation object and three radio wave emission devices. According to the method, distance measurement can be achieved through time measurement, so that elastic deformation of a steel structure can be measured, and the method has the advantages of being simple in tool and convenient.

Description

technical field [0001] The invention belongs to the field of mechanical deformation measurement, in particular to a method for measuring deformation of steel structures with simple operation. Background technique [0002] The traditional steel structure deformation measurement method mainly adopts the stretching method to measure the elastic deformation by measuring the distance. The defect of this method is that. The measurement tools and measurement process are relatively complicated, and the time difference caused by the difference in the transmission distance of the deformation to the electromagnetic wave propagation process can be used to measure the distance by measuring the time, thereby measuring the deformation of the steel structure. Contents of the invention [0003] The object of the present invention is to provide a method for measuring the deformation of a steel structure with simple operation. [0004] The technical solution to achieve the above purpose is:...
