Magnetic pneumatic clamping type core picking clamp for engineering quality

Abstract

The invention provides a magnetic pneumatic clamping type core picking clamp for engineering quality, and relates to the technical field of engineering quality. The magnetic pneumatic clamping type core picking clamp for the engineering quality comprises a housing, wherein an electric magnetism generating device is fixedly connected to the inner wall of the housing. According to the magnetic pneumatic clamping type core picking clamp for the engineering quality, the electric magnetism generating device is used in match with a rubber airbag; when concrete is picked from a sampler, the housing is inserted into the sample, then the electric magnetism generating device is electrified, and the magnetism generated by the electric magnetism generating device is the same as the magnetism at the outer side of a movable magnetic block, the electric magnetism generating device repels the movable magnetic block, and thus the movable magnetic block moves toward the inner side; when a propping rod is in contact with the rubber airbag and is clamped to a limiting groove, a clamping rod is extruded out to be clamped to the clamping groove, the position of the movable magnetic block is fixed, and air at the inner side is extruded into the rubber airbag through the movable magnetic block, so that the rubber airbag is expanded to clamp the concrete sample, and as a result, the concrete sample canbe completely picked out, the effect of conveniently picking out the sample is achieved, the completeness of the concrete is ensured, and the detection accuracy is improved.

Description

Technical field [0001] The invention relates to the technical field of engineering quality, in particular to a core clamp for engineering quality clamped by magnetic air pressure. Background technique [0002] Engineering quality is an important criterion for the acceptance of construction projects. The inspection is used to determine whether the quality of the construction project has passed the test, so as to determine whether the building can be put into use. Only buildings with qualified quality can be put into use, ensuring the life safety of users. [0003] One of the current building surveys is concrete testing. Most of the current concrete testing is taken out of the building through a sampler. Most of the removed concrete is left in the sampler, which is not easy to take out. Generally, it is gently removed from the surrounding area with tweezers. Cut out the concrete, but because the concrete is not completely set, it is easy to cause damage to the concrete block, which m...

[0003] One of the current building surveys is concrete testing. Most of the current concrete testing is taken out of the building through a sampler, resulting in most of the taken out concrete being left in the sampler, which is not easy to take out. The concrete is cut out, but because the concrete is not completely condensed, it is easy to cause damage to the concrete block, which makes the detection difficult, the detection result is not accurate enough, and errors are prone to occur, and different concrete blocks have different densities. On the basis of not destroying the structure, The extrusion force that can withstand is also different, it is difficult to guarantee the accuracy of detection
