Abstract
Concrete is split and is drawn experimental filler strip of using including backing plate, a plurality of supporting shoe and a screw, sets firmly the arch of an arc at the middle part of a backing plate terminal surface, and it is equipped with a plurality of screw holes to distribute in the both sides of backing plate, is equipped with waist shape hole on the supporting shoe, and the supporting shoe passes through waist shape hole and the detachable connection of screw in the both sides of backing plate, the to -be -solved technical problem of the utility model is to provide a concrete is split and is drawn experimental filler strip of using can conveniently be applicable to the test piece of multiple different specification and multiple size to the error that causes is drawn to current the splitting of effective solution among the testing method.
Description
Technical field
The utility model relates to concrete wedge interfere filler strip, belongs to mechanical field.
Background technology
Concrete wedge interfere is one of test method measuring Tensile strength, test method puts one block of filler strip on the test specimen of material between lower support surface and pressure plate of press machine, make test specimen top and bottom form corresponding bar shaped to load, cause test specimen to destroy along the splitting of tangent plane, thus record concrete tensile strength.
As shown in Figure 5, in existing wedge interfere process, filler strip and test specimen contact area are very little, it is very difficult to align between two parties with upper bottom support surface, can produce slippage deviation while preload. When the less ratio of sample dimensions is easier to alignment error, but the bigger deadweight of sample dimensions is relatively big, produces error and is difficult to adjustment, directly affect test-results, be related to the accuracy of experimental study in process of the test.
Summary of the invention
The technical problems to be solved in the utility model is to provide concrete wedge interfere filler strip, it is possible to conveniently be applicable to multiple different size and the test specimen of multiple size, and effectively solves in existing wedge interfere method the error caused.
The technical solution of the utility model is: concrete wedge interfere filler strip, comprise one piece of backing plate, multiple support block and screw, the projection of a circular arc it is installed with at the middle part of backing plate end face, it is distributed with multiple threaded hole in the both sides of backing plate, support block is provided with a waist shaped hole, supports block by the detachable both sides being connected to backing plate of waist shaped hole and screw.
Further, the shape of described support block is " L " shape.
Further, described screw is interior hexagonal screw.
The beneficial effects of the utility model are: support the waist shaped hole energy height up and down on block, first the end face supporting block is adjusted to arc-shaped convex contour, support block is fixed on backing plate by furbuckles, screw is unclamped after concrete test block preload, support block downslide and lose bearing capacity, thus complete wedge interfere and efficiently solve in existing wedge interfere the error problem existed, and complete assembly structure is simple, volume is less, flexibly easy to control, record the more realistic situation of data, meet wedge interfere code requirement.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is the utility model wherein a kind of perspective view implementing mode,
Fig. 2 is another perspective view implementing mode of the utility model,
Fig. 3 is the perspective view that the utility model supports block,
Fig. 4 is the utility model front view in use,
Fig. 5 is the mentioned front view to existing wedge interfere in background technology.
Embodiment
The technical progress being easier to understand the utility model to allow those skilled in the art prior art being made, before the utility model is elaborated, first to mentioned by background technology to existing wedge interfere be described in further detail.
As shown in Figure 5, generally doing wedge interfere can at pressing machine 4 and concrete test block 6 and the filler strip 5 of a long strip shape on pad between concrete test block 6 and operator's console 7, but filler strip 5 compares narrow, and end face is cambered surface, thus very little with concrete test block 6 contact area, relatively more difficult and upper bottom support surface aligns between two parties, and preload can produce slippage deviation simultaneously. When the less ratio of test block 6 size is easier to alignment error, but the bigger deadweight of test block 6 size is relatively big, produces error and is difficult to adjustment, directly affect test-results, be related to the accuracy of experimental study in process of the test.
In order to solve problem existing in above-mentioned prior art, the utility model provides a kind of concrete wedge interfere filler strip, and concrete structure is if Fig. 1 is to shown in 3:
Concrete wedge interfere filler strip, comprise one piece of backing plate 1, multiple support block 2 and screw 3, the projection 11 of a circular arc it is installed with at the middle part of backing plate 1 end face, it is distributed with multiple threaded hole in the both sides of backing plate 1, support block 2 is provided with a waist shaped hole 21, supports block 2 by the detachable both sides being connected to backing plate 1 of waist shaped hole 21 and screw 3.
Further, the shape of described support block 2 is " L " shape.
Further, described screw 3 is interior hexagonal screw 3, because the gap between concrete test block 6 and operator's console 7 is narrow, adopt the words of outer-hexagonal screw 3, common spanner not too conveniently unclamps screw 3, and adopt in hexagonal screw 3 just can well address this problem, it is possible to use the internal hexagonal screw 3 of king-size socket screw hexagon wrench is relaxed.
Using method of the present utility model: as shown in Figure 4, first by the waist shaped hole 21 on support block 2, by support block 2 up-down adjustment to contour with the arc-shaped convex 11 on backing plate 1, and then by fastening for interior hexagonal screw 3, concrete test block 6 is placed on this filler strip, and filler strip is adjusted to the middle position of concrete test block 6.
Re-use aforesaid method, prepare one block of filler strip in addition, be placed on the upper surface of concrete test block 6, and be adjusted to middle position. Concrete test block 6 is carried out preload by this filler strip by final pressure machine 4, after to be loaded, loosen the interior hexagon bolt on upper lower support block 2, supporting block 2 and lose bearing capacity along waist shaped hole 21 downslide, concrete test block 6 is carried out loading and completes wedge interfere by the arc-shaped convex 11 being only on backing plate 1.
