Resistance to plucking and shear behavior under state ensure the construction quality of concrete rear anchor piece and the safe handling of related building, protect
Demonstrate,prove the construction quality of concrete rear anchor piece and the safe handling of related building, it is necessary to carry out concrete post anchoring part resistance to plucking
With the live sampling Detection of shear behavior.
The existing concrete post anchoring part pullout tests equipment that is directed to is mainly by drawing stent, drawing jack, drawing fixture
It is formed with the drawing displacement sensor drawn by drawing fixture, drawing fixture fixed steel bars are usually all that setting is multiple towards reinforcing bar
Bolt, reinforcing bar is withstood by precession bolt, so as to fulfill the fixation to reinforcing bar.However, this kind of fixed form operation is cumbersome,
Time-consuming and laborious, labor intensity is high.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of rear anchor bars simple in structure, easy to use to resist
Pull-out test displacement sensor fixing device.
Used technical solution to solve above-mentioned technical problem：Anchor bar anti-pulling experiment displacement sensor after a kind of
Fixing device including sleeve and sensor, is respectively arranged on the left side and the right side in the sleeve through through hole, is further included two correspondences and is worn
The mandril through through hole is crossed, two mandrel ends are equipped with the clamping end plate that contact is supported with the reinforcing bar of bushing core, in two institutes
It states and compression spring is set on mandril, the compression both ends of the spring is supported respectively between clamping end plate and sleeve lining,
Connecting screw hole is further respectively had at left and right sides of the sleeve, two connecting screw holes are threaded with the fixation to connect with sensor
Bolt.
Further, it is described to run through through hole with connecting screw hole between the upper and lower every on same straight line.
Further, it is externally provided on the mandril positioned at sleeve and supports baffle, the length for supporting baffle, which is more than, passes through
The diameter of reach through hole.
Further, the clamping end plate and to support baffle be arc-shaped end plate.
Advantageous effect：Hereafter in anchor bar anti-pulling experiment displacement sensor fixing device, two clamping end plates are being pressed
Reinforcing bar to be detected in sleeve is supported in the lower clamping of elastic force effect of contracting spring, when reinforcing bar carries out anti-pulling experiment, the displacement of reinforcing bar
Amount is embodied in by mandril on sleeve, and is reflected on the sensor to connect with fixing bolt, is obtained by the reading on sensor
Go out rear anchor bar anti-pull-out property.
Description of the drawings
The utility model is described further with reference to the accompanying drawings and examples；
Fig. 1 is the structure diagram of the utility model embodiment；

Specific embodiment
Referring to Figures 1 and 2, anchor bar anti-pulling experiment displacement sensor fixing device, bag after the utility model is a kind of
Sleeve 10 and sensor (not shown) are included, is respectively arranged on the left side and the right side in sleeve 10 through through hole 11, two correspondences is further included and wears
The mandril 20 through through hole 11 is crossed, the diameter of mandril is adapted with the diameter through through hole 11, ensures to go out in vertical direction
It now relatively moves, two mandrils, 20 end is equipped with the clamping end plate 21 that contact is supported with the reinforcing bar 30 at 10 center of sleeve, in two mandrils
Compression spring 22 is set on 20,22 both ends of compression spring are supported respectively between clamping 10 inner wall of end plate 21 and sleeve.
In use, pull two mandrils 20 so that two clamp the distance between end plate 21 and are more than 30 diameter of reinforcing bar, are convenient for
The positioning of reinforcing bar 30 unclamps two mandrils 20 between two clamping end plates 21 so that two clamping end plates 21 are in compression spring
Reinforcing bar 30 is clamped under 22 elastic force, so as to which reinforcing bar 30 is connected as one with sleeve 10, the displacement that reinforcing bar 30 generates is embodied in set
On cylinder 10.
Wherein, connecting screw hole 12 is further respectively had in 10 left and right sides of sleeve, through through hole 11 and connecting screw hole about 12
On same straight line, two connecting screw holes 12 are threaded with the fixing bolt (not shown) to connect with sensor at interval, sensing
Device is preferably dial gauge, and when reinforcing bar 30 carries out anti-pulling experiment, the displacement of reinforcing bar 30 is embodied on sleeve 10 namely is embodied in
On fixing bolt, by the displacement of centimeter check fixing bolt, rear anchor bar tension is drawn according to the reading on dial gauge
Pull out performance.
Support baffle 23 preferably, being externally provided on mandril 20 positioned at sleeve 10, support baffle 23 length be more than pass through
The diameter of reach through hole 11 can limit mandril 20 under compression 22 elastic force of spring effect by supporting baffle 23 and to center continue to move
It is dynamic.
Preferably, it is arc-shaped end plate to clamp end plate 21 and support baffle 23.
The embodiment of the utility model is explained in detail above in conjunction with attached drawing, but the utility model is not limited to
Embodiment is stated, in the knowledge possessed in the technical field those of ordinary skill, this practicality can also not departed from
Various changes can be made on the premise of new objective.
