The splicing assistant fixture comprises a locating base, a sliding block, two splicing blocks and two loading rods, wherein the locating base is in a U-shaped structure; the sliding block is in an L-shaped structure; the sliding block can slide along a through trough and passes through a through hole via a bolt to be cooperated with the through trough to fix the sliding block and the locating base; the side wall of the sliding block is cooperated with the wall surface of the other side wall of the locating base to fix the splicing blocks and composite material laminating thick plate to be tested; the splicing surfaces of the splicing blocks are provided with U-shaped grooves; the size of the groove is the same as that of the end surface of the composite material laminating thick plate to be tested; and a threaded blind hole is formed in the center of the side surface of one side opposite to the splicing surface. The pressure direction of the sliding block in the splicing assistant fixture is vertical to the bonding surface of the splicing blocks and a test sample to ensure that the splicing blocks and the test sample do not twist when being solidified in the locating base. The grooves are formed on the splicing surfaces of the splicing blocks, so that the splicing blocks and the test sample are ensured not to twist in the further solidifying process.
Description
Technical field
The present invention relates to the composite property field tests, be specially a kind of bonding auxiliary clamp that is used for composite laminated slab tensile and compressive property test.
Background technology
At present both at home and abroad when carrying out the test of composite laminated slab thickness direction tensile and compressive property; Adopt high-intensity epoxy glue that layer is closed slab sample coupon end often and the load bar end bonds together; In order to guarantee the accuracy of tensile and compressive property test; Avoid the unrelieved stress of bonding place, in existing technique for sticking, all will the shape the same with the sample coupon end be processed in the load bar end; But at present the time with load bar end and the bonding of sample coupon end; Often only be with range estimation or with ruler in the end than reciprocity method with definite to neutrality, will inevitably cause alignment deviation thus, and small alignment deviation also can influence the degree of accuracy of test result data.In addition, binding solidification process needs 24 hours set time at least, in this process, need load bar and sample coupon be kept fixing under certain pressure.
A kind of anchor clamps are disclosed in application number is 201110107373.5 application for a patent for invention; These anchor clamps are through providing pressure on the bonding direction; Having solved originally with manual work or weight is problems such as the pressure that exists in the main fixed form is inhomogeneous, alignment deviation, but these anchor clamps lack perpendicular to the constraint of binding on the direction, causes in solidification process; Test specimen and bond pad twist easily under pressure, thereby influence the degree of accuracy of test result data; Owing to adopt a small amount of anchor clamps that a large amount of samples are carried out adhesive solidification often in the engineering practical application, need the solidification process of sample be solidified in anchor clamps and have anchor clamps now always, thereby cause the anchor clamps service efficiency low in addition.
Summary of the invention
The technical matters that solves
For solving the problem that exists in the prior art, the present invention proposes a kind of bonding auxiliary clamp that is used for composite laminated slab tensile and compressive property test.
Technical scheme
Technical scheme of the present invention is:
Said a kind of bonding auxiliary clamp that is used for composite laminated slab tensile and compressive property test is characterized in that: comprise positioning base, slide block, two bond pads and two load bars; Positioning base is " U " type structure, on the bottom surface of positioning base, has many parallel perforation chutes, connects the side wall surface of chute direction perpendicular to positioning base; On the side wall surface of positioning base, have a plurality of bolt holes, be used to pass jackscrew slide block is exerted pressure near the perforation chute; Slide block is " L " type structure, has a plurality of through holes on slide block and the bottom surface that positioning base contacts, and slide block can be along connecting that chute slides and passing through hole and connect chute and cooperate slide block and positioning base are fixed through bolt; Slider side wall cooperates with the opposite side wall of positioning base fixes bond pad and composite laminated slab to be measured; Bond pad is a rectangular structure, has " U " type groove on the bonding plane of bond pad, and groove size is identical with composite laminated slab face size to be measured, and the side side center relative with bonding plane has tapped blind hole; There is external thread load bar one end end, is used for being connected with the bond pad tapped blind hole.
Beneficial effect
The pressure direction of slide block has guaranteed can not twist when bond pad and sample solidify in positioning base perpendicular to the bonding direction of bond pad and sample among the present invention; And on the bonding plane of bond pad, have groove, also guaranteed when the process of after positioning base takes out, further solidifying bond pad and sample, can not twist.Further; Because the existence of bonding plane upper groove; Take out after can bond pad and sample being solidified the short period in positioning base; Adopt G shape carpenters' clamp further to apply extruding force, so just shortened the occupied time of positioning base in the single process greatly, improved the service efficiency of anchor clamps.

Embodiment
Below in conjunction with specific embodiment the present invention is described.
Embodiment:
Present embodiment is for carrying out the tensile and compressive property test to the composite laminated slab sample coupon of a kind of waist shape.
With reference to accompanying drawing 1, said bonding auxiliary clamp comprises positioning base 2, slide block 3, two bond pads 4 and two load bars 1.Whole auxiliary clamp is processed by high-strength stainless steel.
With reference to accompanying drawing 1, accompanying drawing 2 and accompanying drawing 4; Positioning base is " U " type structure; Positioning base is used to place style, bond pad and slide block, on the bottom surface of positioning base, has two parallel perforation chutes, connects the side wall surface of chute direction perpendicular to positioning base; Connect chute and be used to limit the direction of motion of slide block, and connect fixedly slide block and positioning base; On the side wall surface of positioning base, have two bolt holes, be used to pass jackscrew slide block is exerted pressure near the perforation chute; Positioning base opposite side wall is used for cooperating with slider side wall and grips style and bond pad.
With reference to accompanying drawing 3, slide block is " L " type structure, the length of slide block length and sidewall height and positioning base groove and degree of depth coupling; On slide block and bottom surface that positioning base contacts, have two through holes, slide block can slide along connecting chute, and passes through hole and connect chute and cooperate slide block and positioning base are fixed through bolt 5; The effect of slide block is to cooperate with the opposite side wall of positioning base through its sidewall bond pad and style are fixed, and the pressure direction of slide block has avoided bond pad and style in binding solidification process, to twist perpendicular to the bonding direction of bond pad and style.
