A kind of half grout sleeve anchorage length of steel bar detection device
Technical field
The utility model relates to the anchorage length detection field of reinforcing bar, more particularly to a kind of half grout sleeve Bar Anchorage are long
Spend detection device.
Background technique
Grout sleeve is by the assembly for sleeve, mating grouting material and the reinforcing bar assembling specially processed, and the technology of connection is former
Reason is: after connection reinforcing bar insertion sleeve, dedicated grouting material being poured into sleeve, full of the gap between sleeve and reinforcing bar, grouting material
It is tightly engaged after hardening with reinforcing bar cross rib and sleeve lining formation, and the effective force between reinforcing bar and sleeve, i.e., by two steel
Muscle links together.Sleeve grouting connector have many advantages, such as reliable performance, applicability extensively, simple installation.Grout sleeve connects skill
Art is suitable for the engineering fields such as reinforced concrete structure, bridge structure.
Half grout sleeve connects reinforcing bar using straight thread mode at prefabricated components end, and assembled in situ end is connected using grouting way
Reinforcing bar is connect, the connection of vertical member (wall, column) is generally primarily adapted for use in.
Anchorage length of steel bar refers to that suffered power is passed to concrete by the bonding of concrete and rebar by steel bar stress
Required length, if reinforcing steel bar bear cannot effectively pass to anchoring body without enough anchorage lengths, to guarantee reinforcing bar
Power transmission effect should specifically anchor condition to the shadow of adhesion strength according to the stress condition of reinforcing bar, protective layer thickness, reinforcing bar form etc.
It rings, the anchorage length of reinforcing bar is determined by code requirement.
The anchorage length of reinforcing bar is the key point of assembled arthitecutral structure quality control, is directly related to the entirety of building
Structure safety.Based on process control, construction site there is no specific detection method for the detection of anchorage length, lead to not determine
Whether the anchorage length of full grout sleeve reinforcing bar meets code requirement, and the stress of reinforcing bar is effectively passed to anchor to not can guarantee
Solid.
