A steel bar protective layer detector

Abstract

Disclosed is a reinforcing steel bar protection layer detector. The reinforcing steel bar protection layer detector comprises a machine shell and a protection layer detection system arranged in the machine shell; the reinforcing steel bar protection layer detector is characterized in that a marking device which is in linkage with the protection layer detection system is further arranged in the machine shell; the protection layer detection system comprises a thickness detection module, a preset input module, a control module, an alarm module and a marking execution module; and when the thickness of the protection layer is smaller than the preset thickness, the marking execution module drives the marking device to mark the concrete wall body while alarming is performed through the alarm module. Therefore, the problems existing in the concrete pouring process can be conveniently analyzed by workers, so that the same error can be avoided as much as possible in the concrete pouring processof the next step. Meanwhile, the detector only needs to detect the thickness of the concrete, so that the manufacturing cost is lowered and the detector is suitable for use in the construction process.

Description

technical field [0001] The invention relates to a detection device for concrete construction, in particular to a steel bar protective layer detector. Background technique [0002] Rebar cover is the distance from the outer edge of the outermost rebar to the concrete surface. In the durability design, unless otherwise specified, this protective layer shall be the protective layer of the outermost reinforcement. In order to protect steel bars from corrosion and ensure the structural strength of concrete building structures, strict requirements are imposed on the thickness of the protective layer in the prior art. Generally, after the building construction is completed, the thickness of the protective layer will be detected by a third party through the steel protective layer detector. The staff will hold the detector and move along the concrete surface, and realize the detection of the thickness of the protective layer through the detection coil in the detector. . However, b...

Problems solved by technology

However, because the third party generally inspects the protective layer after the construction is completed, on the one hand, when the protective layer is inspected, the concrete building has been constructed according to the construction habits of the construction personnel. Many problems have occurred, requiring construction personnel to carry out large-scale repairs; on the other hand, due to the requirements of the third-party detection range, the function of the steel protection layer detector in the prior art is complicated, not only detecting the thickness of the protection layer, but also It also evaluates other standards of steel bars, such as the diameter of steel bars, etc., which makes the cost of steel bar cover detectors high and is not suitable for large-scale promotion and use.
