Description
Technical field:
The utility model relates to construction material performance measurement device technical fields.
Background technique:
In concrete filled steel tubular member loading process, the bonding problem between steel pipe and core concrete is always to study
One of the hot issue of person's concern, in high-rise and super-high building structure, the dead load and live load acted on above fine strain of millet is
Column is passed to by bean column node.If rod structure uses concrete filled steel tube, the shearing of beam-ends is not to be directly passed to core
Concrete, but it is transmitted to the steel pipe of outside first.The strain between steel pipe and concrete is generally assumed that in previous research is
It is totally continuous, and actually their strain and non-fully continuous, there are certain sliding and bondings between steel and concrete
Intensity.Currently, it is more troublesome in relation to adhesion strength measurement between steel pipe and concrete, it is not easy to calculate.
Summary of the invention:
In consideration of it, it is necessary to design a kind of dedicated measuring device, to measure the adhesion strength between steel pipe and concrete
Data.
A kind of concrete filled steel tube bonds force test device, comprising: pedestal, rack, top plate, displacement meter, pallet, hydraulic

Different sizes part to be measured is measured in the case where being changed without top plate, pallet, improves equipment application range.Meanwhile at this
Under design structure, since the actuating mechanism of top plate expansion bracket exists, structural strength is poor with respect to top plate itself, therefore measures coagulation
The deformation of top plate expansion bracket need to be excluded when soil displacement to be influenced, and further, is displaced in respect of two groups, wherein one group of contact and measuring top plate
Expansion bracket tip displacement.
Preferably, Driven by Hydraulic Cylinder mechanism includes fuel tank, driving motor, petroleum pipeline, oil return pipe and purification device, fuel tank with
