[0002] In foundation pit support projects, steel sheet piles are often used to support the foundation pit, and the steel sheet piles are surrounded by H-shaped steel purlins. Affected by external factors, H-shaped steel purlins are prone to longitudinal and lateral displacement, affecting construction safety; therefore, it is extremely important to monitor the deformation of H-shaped steel purlins. The existing technology often fixes the displacement sensor on the H-shaped steel purlin, receives the displacement signal of the displacement sensor through the data acquisition terminal and obtains the displacement data, so as to monitor the deformation of the H-shaped steel purlin; however, this method has the following problems: when the displacement sensor needs to be moved to another place for monitoring, it is necessary to first release the displacement sensor from the H-shaped steel purlin, and then fix it at the position to be monitored; this operation is cumbersome and inefficient.

[0003] Therefore, it is extremely important to propose a deformation monitoring device for an H-shaped steel purlin that can quickly move a displacement sensor and quickly fix the displacement sensor on the H-shaped steel purlin. Utility Model Content

[0006] A first bolt hole is opened at the bottom of the concave block; the displacement sensor is located above the bottom of the concave block and is bolted to the bottom of the concave block through the first bolt hole;

[0007] A third bolt hole is provided on the left side of the concave block; the third bolt hole is used for the bolt to pass through the third bolt hole and abut against the left flange of the H-shaped steel purlin.

[0008] Furthermore, the bottom of the concave block is provided with second bolt holes on the left and right sides of the first bolt hole.

[0009] Furthermore, a horizontal block is connected to the top right side of the concave block, and a level bubble is provided on the upper surface of the horizontal block.

[0010] Furthermore, the right end of the horizontal block is downwardly connected to a vertical block.
