Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of measuring devices, and in particular relates to a device for measuring the thickness of a protective layer of a pier column steel bar. Background Art
[0002] During the construction of bridge piers, the pier column steel bar protective layer is a crucial link in the construction process, which is related to the overall quality and self-strength of the pier column. If the thickness of the steel bar protective layer does not meet the specification requirements, it will cause quality structure and bearing capacity problems to the pier column itself, and will also affect the durability of the pier column. In the existing technology, before the pier column formwork is completed and the concrete is poured on the pier column, the thickness of the steel bar protective layer needs to be measured. When measuring, the surveyor must go down into the formwork to measure the distance from the outside of the steel bar to the inside of the formwork (the pier column steel bar cage is generally composed of vertical bars and ring bars. What needs to be measured here is the distance between the outside of the ring bar and the inside of the formwork). At present, the existing measurement method generally uses an ordinary steel tape measure for measurement. However, since the steel tape measure is easy to bend and is not easy to be straightened horizontally to contact the inside of the formwork, at the same time, because the spacing between some upper and lower ring bars is narrow, it is difficult for construction workers to pass their arms through the gap between the upper and lower ring bars to help the steel tape measure maintain a stable horizontal state, thereby affecting the convenience of measurement and the accuracy of readings. Utility Model Content

[0008] The beneficial effect of this improvement is that when the splint and the clamp seat move in opposite directions, the splint drives the pull rod to move outward to compress the spring. When the annular rib is located in the gap between the clamp seat and the splint, the force applied to the splint is released, and the pull rod drives the splint to move back and reset under the action of the spring, so that the splint and the clamp seat cooperate to clamp the annular rib, and the position of the measuring mechanism can be fixed.
[0009] In order to facilitate the outward movement of the splint and the holding of the clamping mechanism:
[0010] As a further improvement of the above technical solution: a handle is horizontally provided at the middle of the other end of the clamping plate away from the clamping seat.

[0012] To enhance stability when holding the handle:
[0013] As a further improvement of the above technical solution: an anti-slip portion is provided on the outer wall of the handle.
[0014] The beneficial effect of this improvement is that by providing the anti-slip portion on the outer wall of the handle, the friction coefficient can be increased and the stability when holding the handle can be enhanced.
[0015] In order to facilitate the rotation of the gears, confirm the horizontal state of the measuring mechanism, and clearly view the measured values and horizontal state:
[0016] As a further improvement of the above technical solution: the fixing seat is arranged at the top of the clamping seat, the knob is located in the middle of the front end of the fixing seat, and the level and the lighting lamp are located at the top of the fixing seat.
