Technical field
The utility model relates to the anchorage length detection field of reinforcing bar more particularly to a kind of full 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 reinforcing bar is inserted into sleeve, mating grouting material being poured into sleeve, full of the gap between sleeve and reinforcing bar, grouting material hardening
It tightly engages, and the effective force between reinforcing bar and sleeve, i.e., connects two reinforcing bars with reinforcing bar cross rib and sleeve lining formation afterwards
It is connected together.Sleeve grouting connector have many advantages, such as reliable performance, applicability extensively, simple installation.Grout sleeve interconnection technique is suitable
For engineering fields such as reinforced concrete structure, bridge structures.
The both ends of full grout sleeve connector are all made of grouting way connection reinforcing bar, and it is current that full grout sleeve applicability is wide
Most popular one kind sleeve grouting joint form, applies in general to the steel of vertical member (wall, column) and cross member (beam)
Muscle connection.
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.

The length that grouting material 7 contacts is the first anchorage length, and the length that the lower member reinforcing bar 4 is contacted with the grouting material 7 is second
Anchorage length, second anchorage length are the anchorage length to be detected.
After grouting is completed and grouting material reaches some strength, by conducting wire by the first tie point and the second tie point and
Direct-flow double bridge links together.The length of full grout sleeve can measure, and the first anchorage length can be before construction according to specification
It is required that pre-setting.When execute-in-place, when the second anchorage length is the length for meeting code requirement, test connects part
It contacting with lower member reinforcing bar, whole device is a system at this time, and the external direct-flow double bridge can show resistance readings, this
The anchorage length of Shi Yaoqiu detection can be subtracted the anchorage length of upper member reinforcing bar by the length of full grout sleeve, then subtract cavity
It is obtained after length.
The working principle of the utility model is:
The utility model proposes test connect part the inside of full grout sleeve be set, with spring by upper member steel
Muscle is connected together with lower member reinforcing bar, has no effect on grouting quality；The rigidity of spring is enough, guarantees that spring is not in filling process
The position changing of the relative positions or deformation occurs.
After grouting is completed and the grouting material reaches some strength, connected by the first tie point described in conducting wire and second
Point and direct-flow double bridge link together, if upper member reinforcing bar and the anchorage length of lower member reinforcing bar are enough, test
Connecting part can contact with lower member reinforcing bar, and whole device is a system at this time, and external direct-flow double bridge can show electricity
Resistance reading.When direct-flow double bridge shows resistance readings, the circuit for illustrating that the utility model designs is switched on, because of test contact
The rigidity of spring in connector is enough, guarantees that the position changing of the relative positions or deformation do not occur for spring in filling process, circuit connects meaning
Taste the length of cavity at this time be the length set in advance according to code requirement, then the full grout sleeve of measurement can be passed through
Length, then subtract the length of cavity at this time, then subtract the anchorage length of upper member reinforcing bar, so that it may detect lower member steel
Whether the anchorage length of muscle is the anchorage length for meeting code requirement.
What the utility model used is the method that measures indirectly to detect the anchorage length of full grout sleeve reinforcing bar, with this side
Method can determine whether anchorage length of steel bar is enough inside full grout sleeve, build to realize and pour the above assembled of thickness 300mm
Build the on-site test of the full grout sleeve anchorage length of steel bar of connecting elements.
