As further describing for above-mentioned technical proposal:
The bottom of the second reinforcing bar fixed frame is welded with is clamped the position limiting slide block used with limit sliding chutes.
As further describing for above-mentioned technical proposal:
The height of the first reinforcing bar fixed frame and the second reinforcing bar fixed frame is equal, and the first reinforcing bar fixed frame and the second steel The height of muscle fixed frame fixed steel bars is located on the center line of limit casing.
As further describing for above-mentioned technical proposal:
The output end of the controller and the input terminal of cylinder are electrically connected.
As further describing for above-mentioned technical proposal:
The skid resistance strip direction of first stationary fixture and the second stationary fixture bottom is opposite.
In the utility model, first by being equipped with limit casing, reinforcing bar can be socketed by limit casing, into It when row tension test, flies out when reinforcing bar can be prevented to be broken, staff is damaged, stretched to improve the reinforced steel bar strength Secondly the safety of experimental rig by being equipped with multiple stationary fixtures in chuck body, matches co-clip by multiple stationary fixtures Tool ontology carries out independent multiple spot and fixes, and falls off when to prevent steel bar stretching so that reinforcing bar fixed frame more steps up reinforcing bar fixation Gu.

Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.
Referring to Fig.1-3, reinforced steel bar strength tensile test apparatus, including firm banking 1, top one end spiral of firm banking 1 It is fixed with the first reinforcing bar fixed frame 3, the side that the top of firm banking 1 is located at the first reinforcing bar fixed frame 3 passes through 6 spiral of supporting rack It is fixed with limit casing 5, reinforcing bar 4 is connected on the first reinforcing bar fixed frame 3, and reinforcing bar 4 is through limit casing 5 and firm banking 1 On slidably connect the connection of the second reinforcing bar fixed frame 7, the rear side of the second reinforcing bar fixed frame 7 is connect with hydraulic telescopic rod 8, firm banking The side that 1 top is located at hydraulic telescopic rod 8 is connected with cylinder 9, and one end that firm banking 1 is located at cylinder 9 is fixed with controller 10, Limit sliding chutes 11 are offered on firm banking 1, and fixture sheet is respectively connected on the first reinforcing bar fixed frame 3 and the second reinforcing bar fixed frame 7 Body 12, and chuck body 12 is internally embedded and is connected with the first stationary fixture 13 and the second stationary fixture 14, the front housing of firm banking 1 It is coated with graduated scale 2 at the top of body.
