Description

Deposit roof beam district precast beam, board bottom plate reinforcing bar protective layer thickness and detect auxiliary device

Technical Field

The utility model relates to a detection device for concrete building specifically is depositing roof beam district precast beam, board bottom plate reinforcing bar protective layer thickness and detecting auxiliary device.

Background

The first project is a solution and an auxiliary device which are provided for how to rapidly and accurately detect the thickness of the protective layer of the precast beam and the slab bottom plate in the process of detecting the thickness of the protective layer of the steel bar of the precast beam and the slab bottom plate in a beam storage area, and hopes that the thickness of the protective layer of the precast beam and the slab bottom plate can be accurately detected by researching and manufacturing the device, so that the overall engineering quality of the precast beam and the slab is improved, and the investment of manpower and material resources is reduced.

Secondly, as is well known, the reinforced concrete protective layer is a concrete layer with a certain thickness wrapped outside the steel bars. The composite material has important functions in the aspects of ensuring the stress performance, the safety and the durability of the structure, the fire resistance of the structure and the like. The steel bar protective layer thickness detection item has also been specified as a key item in the latest edition civil engineering JTG F80/1-2017, namely the first volume of highway engineering quality inspection and assessment standards, so that the importance of the steel bar protective layer thickness can be seen, and higher requirements on the detection frequency and accuracy are provided. The most important engineering quality control is the control in advance and in the process, the thickness quality control of the precast beam and the plate steel bar protective layer is strictly controlled from the processing and installation of the steel bars, and the detection of the precast beam and the plate entity is realized, so that the detection cannot be carried out after the precast beam and the plate are transported to a bridge erected on site, and in case of quality defects, serious progress and cost loss can be caused. Therefore, the detection work can be completed in the beam storage area as much as possible in the thickness detection of the protective layers of the precast beams and the plate steel bars, and unnecessary loss is avoided. The thickness of protective layers of most prefabricated beams and plates is detected by detecting webs (because the webs are positioned at two sides of the prefabricated beams and plates and are all exposed outside (in the open places), the detection is easy to operate by testers, the detection coverage area is also larger, the protective layers of steel bars on the bottom surfaces of the prefabricated beams and plates are not easy to detect, the prefabricated beams and plates are transported to a beam storage area for storage after being poured, the bottom plates are relatively short from the ground, the testers cannot enter the beam to carry out comprehensive detection operation on the prefabricated beams and the concrete protective layers of the bottom plates of the plates, the main body engineering is comprehensively detected in the quality control of the concrete structure main body, so that no dead angle is left for quality monitoring, when a plurality of construction units detect the protective layers of the prefabricated beams and the bottom plates of the prefabricated beams and the plates, the testers need to lift the prefabricated beams and the plates by hoisting machinery and then squat on the site to detect under the beams, and thus great danger, and the elevation angle using instrument is inconvenient to detect, brings a lot of difficulties to the detection of the bottom plate protective layer, and undoubtedly consumes a lot of time. Some are to build two pressure-bearing walls, and establish precast beam, grillage above, and the measurement personnel stand and detect at the bottom, detect like this and both consumed time, consumed financial resources, material resources again, also had certain risk simultaneously.
