Specific embodiment
Many details are explained in the following description in order to fully understand the utility model.But this is practical new
Type can be implemented with the other modes for being much different from this description, and those skilled in the art can be without prejudice to the utility model
Similar popularization is done in the case where intension, therefore the utility model is not limited by the specific embodiments disclosed below.
Embodiment 1
A kind of core sample installs fixture of concrete Intensity of Breaking Tester provided by the utility model, as shown in Figs. 1-2, including under
Pedestal 1, setting is provided with several rollers 9 in groove 8 there are two groove 8 arranged in parallel on lower bottom base 1.It is propped up under two
Support seat 2 is slidably connected by groove 8 with lower bottom base 1, is reduced the resistance of lower support base 2 and lower bottom base 1, is made to adjust lower support base
More laborsaving when 2 position, operation is more smooth, is conducive to the precise positioning of lower support base 2.Between two grooves 8, it is equipped with one
Item is parallel to the corresponding on seam 10, two lower support bases 2 of groove 8 and is equipped with limit screw 11, limit screw through seam 10
11 may pass through and compress lower support base 2 and pedestal through seam 10, it is therefore prevented that two lower support bases 2 are subjected to displacement when test.
It is symmetrical arranged on the opposite face of two lower support bases 2 there are two swingable connecting rod 3, it can be in installation core sample 13
When connecting rod 3 is swung to the position for not influencing core sample 13 and placing.Specifically, connecting rod 3 includes sleeve 301,302 and of solid hopkinson bar
Locating rod 303.One end of sleeve 301 is hinged on lower support base 2, solid hopkinson bar 302 be nested in the other end of sleeve 301 and with
It is flexibly connected, to adjust the extension elongation of solid hopkinson bar 302, to adapt to the core sample 13 of different size and length, locating rod 303
To lock solid hopkinson bar 302 on sleeve 301.3 amplitude of fluctuation of connecting rod is excessive in order to prevent, is also arranged outside sleeve 301 limited
Position frame 7, position-limited rack 7 are connect with lower support base 2, are equipped with the elongate holes swung for sleeve 301.
It is parallel to groove 8 on lower bottom base 1 and is additionally provided with scale 4, therebetween, other scale values are by zero for the zero graduation of scale 4
Scale symmetrically increases to 4 both ends of scale, easily and accurately to read the distance of two lower support bases 2.It is additionally provided with above lower bottom base 1
For installing the upper bed-plate 12 of upper support seat 5.Upper support seat 5 is equipped with the via hole to match with upper bed-plate 12, and upper support seat 5 is logical
Via hole is set in the both ends of upper bed-plate 12.Scale 4 is corresponded on upper support seat 5 equipped with protruding portion 14, measurement portion 6 is set to protruding portion
On 14.Specifically, measurement portion 6 is a laser head, is set on protruding portion 14 downwards, when core sample 13 is installed, laser hair
The laser alignment scale 4 penetrated, the spacing that can be accurately read between upper support seat 5, and then improve the precision of test.
In order to guarantee the accuracy of data, the upper end section of lower support base 2, the lower end section of upper support seat 5 are arc
(preferably semi arch), to realize that core sample 13 and the line of lower support base 2, upper support seat 5 contact.
The core sample installs fixture of concrete Intensity of Breaking Tester provided in this embodiment use process is as follows:
The first step adjusts the spacing of two lower support bases 2 according to 13 length of core sample and test requirements document.The size of spacing is two
A lower support base 2 arrives the sum of the reading of 4 zero graduation of scale respectively.
Second step tightens limit screw 11, and lower support base 2 is fixed, moves during the test to prevent it.
Third step adjusts the spacing of upper support seat 5 according to test requirements document.Range estimation is first passed through, the first of upper support seat 5 is carried out
Then the laser head on upper support seat 5 is opened in step positioning, laser head is launched downwards laser, is radiated on scale 4, reads light
Scale value under line is to be accurately positioned.
Core sample 13 is placed on lower support base 2 by the 4th step.For circular core sample, adjust connecting rod 3 swing angle and
Length, then screwed in place bar 303, makes connecting rod 3 clamp circular core sample, circular core sample can be effectively fixed, to prevent
Circular core sample rolls.For prism core sample, solid hopkinson bar 302 need to be only pressed into sleeve 301, connecting rod 3 just will not be right
Prism core sample has any impact, so as to successfully carry out the test of prism core sample.
Finally, it should be noted that the above is only the preferred embodiment of the utility model, it is not limited to practical
It is novel, although the utility model is described in detail referring to embodiment, for those skilled in the art, according to
It is so possible to modify the technical solutions described in the foregoing embodiments, or part of technical characteristic is equally replaced
It changes, but within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should all include
It is within the protection scope of the utility model.
