Background technology
Architecture adhesion agent, as a kind of Reinforcement of Engineering Structure material, has now been widely used in cement concrete constructions, and its performance quality has direct impact to the safety of works, quality, permanance.And the performance of architecture adhesion agent can characterize by cohesive strength.Therefore, to the cohesive strength of architecture adhesion agent, measure significant.For example, Chinese patent (CN102519789A) discloses a kind of mortar surface layer and base body tensile bonding intensity detecting clamp and detection method, it directly clamps mortar surface layer by combined type fastening clips, when extension test, can will between mortar and base material, pull open, thereby obtain the cohesive strength of mortar surface layer and substrate.But when just drawing cohesive strength test, in test specimen adhesion process, unavoidably can produce center line departs from or reverses, make test specimen after on-test, not only bear positive pulling force, also to bear other stress that bias or torsion produce, can not truly reflect that it is just drawing cohesive strength, greatly reduce the degree of accuracy of test figure, bring inconvenience to the experiment testing of related scientific research unit, production unit and unit in charge of construction.
Summary of the invention
For solving the problems of the technologies described above, the utility model provide a kind of eliminate center line depart from or reverse the bonding reinforcing material of dysgenic binding material and base material just draw cohesive strength test fixture.
The bonding reinforcing material of a kind of binding material described in the utility model and base material just draw cohesive strength test fixture, this fixture comprises lower clamp and upper clamp two parts; Described lower clamp comprises steel clamp tool 1, sliding tray 2, strap 3 and slidably reverses stressed pull bar 4, sliding tray 2 is fixed on steel clamp tool 1 bottom, strap 3 with slidably reverse stressed pull bar 4 bottoms and be connected, slidably reversing stressed pull bar 4 tops can free shift and rotation in sliding tray 2; Described upper clamp comprises calibrated bolck 5, sliding tray 7, slidably reverses stressed pull bar 6 and strap 8, sliding tray 7 is fixed on calibrated bolck 5 tops, strap 8 with slidably reverse stressed pull bar 6 tops and be connected, slidably reversing stressed pull bar 6 bottoms can free shift and rotation in sliding tray 7; During use, upper clamp is placed in lower clamp top, base material is fixed in steel clamp tool 1, binding material is by base material top and calibrated bolck 5 bottom adhesive, by adjusting, slidably reverse stressed pull bar 4 and slidably to reverse stress point that stressed pull bar 6 makes base material and calibrated bolck 5 point-blank, finally strap 3 and strap 8 to be fixed on testing machine and to be tested.
Described steel clamp tool 1 is front and back and open-topped four directions cover, and an outstanding crosspiece is respectively established in left and right, top, for fixing substrate.
Each ingredient of described fixture is made by No. 45 carbon steels.
Compared with prior art, the bonding reinforcing material of binding material of the utility model design and the size conforms national standard requirement of just drawing cohesive strength test fixture of base material, it is easy and simple to handle, can eliminate test specimen center line departs from or reverses the harmful effect to test result of the stress that produces, improve test data accuracy, and this fixture is easy to dismounting adjustment, improve test operation convenience.

Embodiment
Below in conjunction with specific embodiment, the bonding reinforcing material of binding material of the utility model design and the cohesive strength test fixture that just draws of base material are described further, but protection domain of the present utility model is not limited to this.
Embodiment 1
As shown in drawings, the bonding reinforcing material of binding material of the utility model design and base material just draw cohesive strength test fixture, this fixture comprises lower clamp and upper clamp two parts; Described lower clamp comprises steel clamp tool 1, sliding tray 2, strap 3 and slidably reverses stressed pull bar 4, sliding tray 2 is fixed on steel clamp tool 1 bottom, strap 3 with slidably reverse stressed pull bar 4 bottoms and be connected, slidably reversing stressed pull bar 4 tops can free shift and rotation in sliding tray 2; Described upper clamp comprises calibrated bolck 5, sliding tray 7, slidably reverses stressed pull bar 6 and strap 8, sliding tray 7 is fixed on calibrated bolck 5 tops, strap 8 with slidably reverse stressed pull bar 6 tops and be connected, slidably reversing stressed pull bar 6 bottoms can free shift and rotation in sliding tray 7; During use, upper clamp is placed in lower clamp top, base material is fixed in steel clamp tool 1, binding material is by base material top and calibrated bolck 5 bottom adhesive, by adjusting, slidably reverse stressed pull bar 4 and slidably to reverse stress point that stressed pull bar 6 makes base material and calibrated bolck 5 point-blank, finally strap 3 and strap 8 to be fixed on testing machine and to be tested; Described base material is concrete test block;
