The utility model discloses during the use, the reinforcing bar one end of steel bar anchoring board test piece can directly be connected with keeping silent of testing machine, and the pull rod of the device upper end also can be kept silent with another of testing machine and is connected to tensile test can carry out, and, because the ball pivot seat and the pull rod design of taking the hemispheroid, can play angle regulation's effect when having the out of plumb between the anchor board of test piece and the reinforcing bar, make the strong adaptability of device, in addition, unique structural design of base for easy to assemble and the dismantlement of test piece, the operation is safe simple.
Description
Technical field
The utility model relates to building materials testing inspection field, is specially a kind of test unit for detecting Bar Anchorage plate test specimen tensile strength.
Background technology
In People's Republic of China's industry standard " Bar Anchorage plate application technology code " JGJ256-2011, define a kind of Bar Anchorage plate test specimen tensile strength test method, need to use the test for tensile strength of a kind of tension test servicing unit compatibility test machine realization to Bar Anchorage plate test specimen.In fact, Bar Anchorage plate test specimen is one section of reinforcing bar that anchor plate is equipped with in one end, when tension test is carried out to it, to one end of reinforcing bar be clamped in the jaw of testing machine, the anchor plate of the other end is stuck in supporting test unit, and test unit should be provided with shaft, in order to be clamped in another jaw of testing machine, the tensile force of such testing machine just can pass to Bar Anchorage plate test specimen by test unit.
Summary of the invention
The utility model provides a kind of Bar Anchorage plate stretching experiment auxiliary device, in order to by the pull transfer of testing machine to Bar Anchorage plate test specimen, easy to use, safe, the out of plumb of appropriateness to be allowed between anchor plate and reinforcing bar.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of Bar Anchorage plate stretching experiment auxiliary device, comprises base, and the top of base is provided with ball pivot seat, the bottom of ball pivot seat is provided with hemispheric groove, ball pivot seat is also connected with pull bar, and the bottom of pull bar is hemisphere, and hemisphere is connected with groove fit, the upper end of pull bar passes ball pivot seat, described chassis interior hollow, one group of relative sidewall opens wide, and bottom is provided with the opening for installing test specimen to be measured.
One end of described opening is positioned at the center of base bottom, and semicircular in shape; The other end extends to the bottom margin of base, is positioned at the below of unlimited sidewall; Be provided with back up pad in described base, the center of back up pad is provided with the through hole for installing test specimen to be measured; The positioning strip for blocking back up pad is also provided with in described base.
Further, base is cube frame, one group of relative sidewall opens wide, the area of back up pad is less than the area of the bottom of base, during installation, by the through hole of reinforcing bar one end of Bar Anchorage plate test specimen through back up pad center, make the anchor plate part of test specimen be close to the upper surface of back up pad, then back up pad and Bar Anchorage plate are installed in base through opening.The both sides of the edge being positioned at unlimited sidewall in the bottom of base are provided with positioning strip, for back up pad being blocked, prevent test specimen from skidding off from unlimited sidewall, ensure handling safety, conveniently install, and positioning strip, being positioned at opening part disconnection, is only arranged on the both sides of opening.After installation, Bar Anchorage plate test specimen is fixed in base, and reinforcing bar passes from semicircle opening side.
Be connected by screw rod between described base with ball pivot seat; The top of concrete base is provided with screw, and ball pivot seat is also provided with the through hole corresponding with base, and screw rod is connected to screw from the top of ball pivot seat through through hole, realizes removably connecting between base and ball pivot seat.
The utility model is owing to adopting said structure design, and reinforcing bar one end of Bar Anchorage plate test specimen can directly be connected with the jaw of testing machine, and the pull bar of this device upper end also can be connected with another jaw of testing machine, thus can carry out tension test; And, due to ball pivot seat and be with hemispheroidal pull bar to design, play adjusting angle when can there is out of plumb between the anchor plate of test specimen and reinforcing bar, make the strong adaptability of device; In addition, the Unique physical design of base, test specimen is easy for installation and removal, and handling safety is simple.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation after test specimen is newly installed in this practicality.
Embodiment
Further illustrate the utility model below in conjunction with embodiment, but the claimed scope of the utility model is not limited to the scope of embodiment statement.
As Figure 1-Figure 2, a kind of Bar Anchorage plate stretching experiment auxiliary device, comprise base 1, the top of base is provided with ball pivot seat 2, the bottom of ball pivot seat 2 is provided with hemispheric groove 21, ball pivot seat 2 is also connected with pull bar 3, and the bottom of pull bar 3 is hemisphere 31, and hemisphere 31 and groove 21 are connected, the upper end of pull bar passes ball pivot seat 2, described base 1 inner hollow, one group of relative sidewall opens wide, and bottom is provided with the opening 11 for installing test specimen to be measured.
One end of described opening 11 is positioned at the center bottom base 1, and semicircular in shape; The other end extends to the bottom margin of base 1, is positioned at the below of unlimited sidewall.
Be provided with back up pad 12 in described base 1, the center of back up pad 12 is provided with the through hole for installing test specimen to be measured.
The positioning strip 13 for blocking back up pad is also provided with in described base 1.
Described base 1 is connected by screw rod with between ball pivot seat 2.
During use, the upper jaw of testing machine clamps the upper end of pull bar, thus is fixed on testing machine by this device.Take out back up pad again, the lengths of rebar on Bar Anchorage plate test specimen is penetrated in the central through hole of back up pad, and make the anchor plate part 41 on Bar Anchorage plate test specimen 4 be close to the surface of back up pad.Then, back up pad is loaded in base together with the opening of Bar Anchorage plate test specimen through base, makes back up pad steadily be contacted with the upper base surface of base, and be located between the positioning strip of both sides.Adjustment Bar Anchorage plate test specimen, makes it be positioned at the vertical on axis of base as far as possible.Finally, Adjustment Tests machine, is clamped in the lengths of rebar 42 of Bar Anchorage plate test specimen protuberate basic unit bottom in testing machine lower jaw.Like this, test specimen installs, and can implement tension test.After stretching terminates, still take out test specimen from device side.
