Technical Field

[0001] The utility model relates to the technical field of reinforced concrete auxiliary devices, in particular to a device for controlling the thickness of a concrete reinforcement protective layer. Background Art

[0002] In reinforced concrete construction projects, the thickness of the steel bar protective layer is an important technical parameter, and the pass rate of the protective layer directly affects the quality and life of the project entity.

[0003] In the prior art, the thickness of the protective layer is mainly controlled by bundling pads with steel bars, which plays a role in controlling the thickness of the protective layer and protecting the steel bars from rust. However, in actual use, the expected technical effects are often not achieved. In addition, in actual use, the steel bar fixing effect is unstable, resulting in problems such as inaccurate position adjustment in the later stage. At the same time, the weight of the steel bars is too heavy, which causes squeezing and damage to the equipment, thereby reducing the service life of the device. Utility Model Content

[0010] The number of the steel bar limiting grooves is several, and the several steel bar limiting grooves are distributed in a circle on the inner surface of the top buckle compartment, and the connection relationship between the latch groove and the latch limiting plate is a movable snap connection.

[0011] Each steel bar limiting groove is in a concave arc structure.

[0012] A buffer extrusion column is fixedly connected to the bottom end of one side of the top limiting plate, a buffer contraction column is telescopically connected to the bottom end of the buffer extrusion column, and a buffer connection spring is fixedly connected to the bottom end of the buffer extrusion column.

A latch limit plate 12 is installed inside the latch groove 11 for fixation. Multiple groups of steel bars are installed at the bottom end of the bottom limit plate 1, and then the spacing between the top limit plate 8 and the bottom limit plate 1 is adjusted by adjusting the effect of rotating the adjusting screw 4 by adjusting the rotating disk 5, so as to realize the control of the thickness of the protective layer, and finally the steel bar is limited and fixed by the top buckle cabin 9 at the top of the top limit plate 8.
