Described anchor clamps comprise that also one is arranged on the jacking block between the clamping part, and described jacking block places on the base plate, and are resisted against the clamping part of arbitrary fixture block, are the processing district between described jacking block and the opposite side clamping part, and described briquetting is arranged on the top of processing district.
Preferably, the two ends of described base plate all are fixed with a bolt, offer groove on each described connecting portion, and described bolt passes groove and is fixed on the base plate, and the diameter of described bolt is greater than the width of described groove, and it is radially movable that each described fixture block is done along slot pitch.
Preferably, described fixture block is provided with screw thread back to setting on the clamping part of at least one fixture block.
The beneficial effects of the utility model are mainly reflected in: install simplely, so that universal testing machine can also can well be used the test with shearing resistance, increased the range of application of testing machine, and good test effect, practical.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Fig. 1: lower clamp structural representation of the present utility model.
Fig. 2: the applicable test of the utility model profile structure synoptic diagram.
Embodiment
The utility model has disclosed a kind of universal testing machine with measuring the shear behavior anchor clamps, comprises lower clamp and upper anchor clamps.
As shown in Figure 1, described lower clamp comprises a base plate 1, and a side center of described base plate 1 is fixedly connected with one and is used for connecting the universal testing machine contiguous block, offers circular hole (meaning not shown in the figures) on the described contiguous block; Described upper anchor clamps are a briquetting, briquetting is a cubic block, and is the same with the fixed form of testing machine with lower clamp, and briquetting one side is provided with the contiguous block of offering circular hole, in concrete fixed form and the prior art on the universal testing machine substitute mode of anchor clamps consistent, do not repeat them here.
The opposite side of described base plate 1 is connected with two fixture blocks, is respectively the first fixture block, the second fixture block.
First, second fixture block is comprised of clamping part and the connecting portion that is vertically connected at clamping part respectively, and fixture block is L-shaped, and described connecting portion is connected on the base plate 1.Two fixture blocks are identical with the connected mode of base plate 1, below concrete fixed form with the second fixture block describe, the two ends of described base plate 1 all are fixed with a bolt 23.Offer groove 22 on the connecting portion 21 of the second fixture block, described bolt 23 passes groove 22 and is fixed on the base plate 1, and the diameter of described bolt 23 is greater than the width of described groove 22.After the location positioning between the fixture block is good, carry out fixing between fixture block and the base plate 1 by bolt 23.
Each described fixture block can be done radially activity by the connecting portion 11 of the first fixture block and the connecting portion 21 of the second fixture block along slot pitch respectively, to adapt to the section bar to be measured of different in width.
Described anchor clamps comprise that also one is arranged on the jacking block 12 between the clamping part, and described jacking block 12 places on the base plate 1, and is resisted against the clamping part of arbitrary fixture block, jacking block 12 is so that section bar is divided into left and right two parts, wherein a part of unsettled, when detecting shear behavior, give section bar enough deformation spaces like this.It is the clamping part that is resisted against the first fixture block shown in the figure.
Be the processing district between described jacking block 12 and the opposite side clamping part, described briquetting is arranged on the top of processing district.Be that described briquetting is that section bar to the opposite side of jacking block 12 presses down all the time.
Described fixture block is back to setting, and in order to increase and the direct friction force of section bar, better fixing section bar is provided with screw thread on the clamping part of at least one fixture block.
The utility model is the performance test for the special-shaped section that is connected and fixed by plastic cement material, is mainly used in testing plastic cement material shear behavior in use.The structural principle of section bar is to be formed by connecting by intermediate 32 by a left side half section bar 31, right half section bar 33 as shown in Figure 2, and the material of intermediate 32 is decided as required.
First anchor clamps are fixed on the universal testing machine, then regulate the distance between anchor clamps, section bar to be measured is fixed on the lower clamp by anchor clamps, the starting characteristics test machine, upper anchor clamps press down, because jacking block 12 is arranged on a side of the below of section bar, form the space between the opposite side below of section bar and the base plate 1, when briquetting presses down, relative motion between left and right half section bar, thus test out the shear behavior of intermediate 32.
The utility model still has multiple concrete embodiment, and all employings are equal to replacement or equivalent transformation and all technical schemes of forming, all drop within the claimed scope of the utility model.
