Background Technique

[0002] At present, concrete structures play a dominant role in projects such as construction, municipal engineering, and road and bridge engineering. For construction enterprises and supervision agencies, ensuring that the parameters on the design drawings are accurately realized during actual construction is a key task. To achieve this goal, it is necessary to accurately control and detect the elevation and dimensions of concrete structures, which not only concerns the quality and safety of the project but also directly affects the service life and performance of the project. Therefore, it is crucial to adopt effective measurement and control methods during the construction process.

[0003] However, at the current stage, during the construction of concrete structures in construction, municipal engineering and other projects, the elevation and dimension control mostly adopts the external measurement method. The external measurement method has certain limitations. Due to repeated measurement errors and differences in the operation methods of operators, the control effect of this method is often not satisfactory, resulting in most plate thicknesses and road surface thicknesses exceeding the error range specified by the design dimensions and specifications.

[0097] Before using a plate thickness control detection instrument with the above design structure, it needs to be installed as a standby.

[0098] The specific usage steps are as follows:

[0099] The present utility model is used in the leveling stage after the concrete is poured and vibrated densely.

[0100] During use, the operator first selects a monitoring point at the position of the leveled concrete 6;

[0101] Then, the operator holds the detection instrument and inserts it vertically into the concrete 6;

[0102] Immediately afterwards, the operator holds the handrail 43 and applies a downward pressure, so that the tip of the conical head 44 of the measuring rod 4 contacts the formwork below the concrete 6. At this time, the scale number displayed at the position of the scale 41 of the measuring rod 4 at the upper port of the locking head 31 is the plate thickness from the upper end face of the concrete 6 to the upper end face of the formwork;

[0103] Finally, after measuring this monitoring point, the operator releases the downward pressure on the handrail 43. At this time, under the elastic action of the spring 5, the weak force spring inside will reset the tray 2 and the measuring rod 4; if multiple monitoring points need to be tested, the operator repeats the above operation process to quickly detect the plate thickness of each monitoring point.

[0104] During the above usage process, when the first plate thickness is detected, the operator can lock the position of the scale 41 of the measuring rod 4 at this time through the fastening member 32. Then, the operator can quickly detect whether the thickness of this area of the concrete 6 is consistent through this plate thickness.

[0105] After use, clean and oil the detection instrument for the next cycle of use.

[0106] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model, and it is not a limitation of the present utility model in other forms.
