Building concrete damage detection equipment

Abstract

The invention discloses building concrete damage detection equipment that structurally comprises a handle, a data collector, a reduction gearbox, a protective shell, a supporting rod and a three-jaw chuck; the handle is fixed on the outer surface of the data collector; the data collector is electrically connected with the reduction gearbox; the three-jaw chuck is controlled by a reduction gearbox; the three-jaw chuck is arranged in the protective shell in a matched mode. The supporting rod is fixed in a crack of the protective shell; a rotary sleeve is movably matched at the joint of the reduction gearbox and the three-jaw chuck; a main screw rod is driven by the rotary sleeve; a rotating mechanism formed by mutual meshing of an auxiliary screw rod and the main screw rod is matched with the three-jaw chuck to realize telescopic access; when the three-jaw chuck is not used or after the three-jaw chuck is used, the three-jaw chuck stretches into rod cavities of the main screw rod and the auxiliary screw rod in a spiral mode; the three-jaw chuck can be directly contained in the protective shell without protection of a protective sleeve; the three-jaw chuck is more portable compared with protective sleeve protection, and the problem that the protective sleeve is difficult to find can also be avoided.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a construction concrete damage detection device. Background technique [0002] Concrete is an indispensable material in the construction process of construction projects. At this stage and for a long time in the future, the economy and applicability of concrete materials are incomparable to many other materials. [0003] However, at present, there are many concretes that are often shoddy, and their strength is not satisfactory, especially in some national key construction projects, the requirements for concrete strength standards are very high, so it is necessary and necessary to test the strength of concrete. The commonly used concrete strength testing techniques in my country are divided into non-destructive testing and micro-damage testing. The pull-off method strength testing technology improved by micro-damage testing in the existing technology mainly uses the correlatio...

[0003] However, at present, there are many concretes that are often shoddy, and their strength is not satisfactory, especially in some national key construction projects, the requirements for concrete strength standards are very high, so it is necessary and necessary to test the strength of concrete. The commonly used concrete strength testing techniques in my country are divided into non-destructive testing and micro-damage testing. The pull-off method strength testing technology improved by micro-damage testing in the existing technology mainly uses the correlation between concrete tensile strength and compressive strength to detect, infer The compressive strength of concrete structures or components, the three-jaw chuck, as the main gripping tool, needs to be stored in a dry and dust-free environment after use, while the three-jaw chuck in the prior art is exposed on the outer surface of the protective shell In the storage, the three-jaw chuck needs to be cleaned first and then put on the sheath. For cleaning and maintenance, only a soft dry cloth can be used or the dry cloth should be soaked in clean water and wrung out before removing dust and dirt. Some The groove wall deep inside is difficult to clean, which is not only troublesome but also time-consuming, and the sheath is often difficult to find due to its small size
