Description
Technical field
This utility model is related to reinforcing bar pull-out test field, more particularly to a kind of reinforcing bar pull-out test test specimen producing device.
Background technology
Reinforced concrete structure referred to structure made by being furnished with the concrete of reinforcing bar, is that most common, application surface is most wide
One class formation.How is cohesive force between reinforcing bar and concrete, and how is bond-slip properties, directly affects reinforced concrete structure
Overall performance and structure safety.Therefore, the cohesive force of reinforcement in concrete and slip property are in reinforced concrete structure theory
One of most important basic problem.
At present, the reinforcing bar adhesion test method being most frequently with is pull-out test, and carrying out pull-out test needs to be produced on coagulation
The test specimen of reinforcing bar is imbedded in native test block.The method for generally making test specimen is to insert reinforcing bar toward on the concrete test block for just having poured.
But on the one hand this method is not easily accomplished the complete vertical centering of reinforcing bar and concrete test block, and this can give follow-up pull-out test
Make a big impact；On the other hand the length of embedment of control reinforcing bar is difficult, so as to cause the deviation of multigroup result of the test.Therefore,
Device to making reinforcing bar pull-out test test specimen is improved, and solves above-mentioned these problems necessary.
Utility model content
Task of the present utility model be to provide a kind of complete vertical centering that can easily realize reinforcing bar and concrete test block with
The reinforcing bar pull-out test test specimen producing device of cohesive force accuracy in pull-out test test is improved to solve the deficiencies in the prior art.
This utility model is achieved through the following technical solutions utility model purpose：
A kind of reinforcing bar pull-out test test specimen producing device, including die trial, die trial top is provided with opening, sleeve, the sleeve
In be arranged with the reinforcing bar coaxially connected with sleeve, the two ends of sleeve are protruded at the two ends of reinforcing bar, thus, are poured into from the opening of die trial
Concrete, further, the lower end edge length sleeve direction of the sleeve offers at least two row's positioning screw holes, and be often ranked a spiral shell
Number of perforations is at least three and is uniformly distributed circumferentially, and the positioning screw hole is provided with the set screw being matched therewith, thus,
Two row's set screws can along its length securely fix sleeve with reinforcing bar, circumferentially disposed at least three positioning screw holes with it is fixed
Position screw can circumferentially securely fix reinforcing bar without rotating, it is ensured that reinforcing bar is hung down completely with the vertical centering of die trial with being obtained
The pull-out experiment of straight centering.
Further, the end that the reinforcing bar stretches into die trial is vertical bar shaped or crotch shape, thus, it is possible to test various reinforcing bars
The cohesive force of end shape and concrete.
Further, described sleeve one end is stretched in the cavity of the die trial, thus, after Cheng Mo between reinforcing bar and concrete
One section of circular space occurred because sleeve is extracted out is had, to avoid the invar muscle insertion when end is tested as crotch shape reinforcing bar
There is the situation that reinforcing bar is surrendered in advance and affects test result deeply very much.
Further, the reinforcing bar is any one in plain bar, Ribbed Bar or twisted bar, can be tested various
Cohesive force between reinforcing bar and concrete.
Further, the die trial is shaped as cube, cuboid or cylinder.
A kind of reinforcing bar pull-out test test specimen producing device that this utility model is provided has advantages below：
（1）Realize reinforcing bar controllable with the vertical centering of concrete test block and length of embedment, improve the examination of pull-out test
Test result；
（2）Whole device simple structure, easy accessibility, moderate cost is especially suitable for the drawing of laboratory and job site
The making of test test specimen；
（3）Die trial size can be adjusted as needed, use bar types variation, widely applicable.
Description of the drawings
Fig. 1 is the structural representation that die trial front is taken apart in this utility model reinforcing bar pull-out test test specimen producing device；
Wherein：1-die trial, 2-opening, 3-base plate, 4-sleeve, 5-reinforcing bar, 6-set screw.
Specific embodiment
Embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of reinforcing bar pull-out test test specimen producing device, including die trial 1, the size of die trial 1 can root
According to needing to be adjusted, the top of die trial 1 is provided with opening 2, and the center of base plate 3 of the cavity of die trial 1 offers circular hole, fixes at circular hole
Be connected with the sleeve 4 vertical with base plate 3, sleeve 4 and die trial 1 adopt steel, and plastic material may also be employed, correspondingly circular hole with
Die trial 1 is adopted and is welded to connect, or is connect in succession by tack adhesive.
Wherein, the reinforcing bar 5 coaxially connected with sleeve 4 is arranged with sleeve 4, the two ends of reinforcing bar 5 protrude the two of sleeve 4
End, for fixes sleeve 4 along its length and reinforcing bar 5, the length direction of lower end edge sleeve 4 of sleeve 4 offers two and is ranked a spiral shell
Hole, or three rows are more multiple rows of, and often arrange positioning screw hole number to three and be uniformly distributed circumferentially with circumference to solid
Determine sleeve 4 and reinforcing bar 5, between three positioning screw holes 120 ° are in, can be configured as four or more positioning screw holes, each
Positioning screw hole is provided with the set screw 6 being matched therewith.
Additionally, the one end of sleeve 4 reinforcing bar 5 occurs in stretching in the cavity of die trial 1 to avoid the too deep insertion concrete of reinforcing bar 5 carrying
Front surrender cannot obtain the situation of test result, and length of the sleeve 4 in die trial 1 can be determined according to practical situation, and sleeve 4 is in examination
Length outside mould 1 will enough with the position of reserved set screw hole 6.
It is vertical bar shaped that reinforcing bar 5 stretches into the end of die trial 1, or crotch shape, hooked angle can for 90 ° or
45 °, reinforcing bar 5 is twisted bar, or plain bar or Ribbed Bar, die trial 1 is shaped as cube, it is also possible to be arranged to
Cuboid or cylinder.
When making reinforcing bar pull-out test test specimen using the device, first the reinforcing bar 5 of required model is penetrated in sleeve 4 and stretched
Enter the certain depth of die trial 1, adjust set screw 6 and realize the vertical centering of reinforcing bar 5 and fix, then, the sleeve 4 in die trial 1
There is annular slot and reinforcing bar 5 between, a certain amount of low-intensity encapsulant is inserted at annular slot（Such as foamed glue）In case
Only concrete is flowed into and affect in sleeve 4 form removal；Subsequently, the base plate side of the device is placed in down on firm supporter；
Then, the concrete being stirred is poured in die trial 1, and fully vibration compacting, finally when concrete reaches strength of mould stripping, enter
Row striking job, the reinforcing bar pull-out test test specimen of the vertical centering of shaping is taken out from die trial 1.
Above-described is only some embodiments of the present utility model.For the person of ordinary skill of the art,
On the premise of design is created without departing from this utility model, some deformations and improvement can also be made, these belong to this practicality
New protection domain.
