Abstract
The utility model discloses a shearing resistance testing clamp. The shearing resistance testing clamp comprises a connection arm, a fixed block and limiting blocks, wherein one end of the fixed block is fixedly arranged at the bottom of the connection arm and the limiting blocks are arranged at the other end of the fixed block; the two limiting blocks are fixedly arranged on the two sides of the fixed block. According to the shearing resistance testing clamp disclosed by the utility model, a force is applied along the axis of a pulled steel bar so as to ensure that a test sample and the clamp are on the same axis; a free end of the pulled steel bar can slide along the axial direction and small-range movement can correct the deviation; furthermore, a transverse steel bar of the test sample is properly fixed and the fulcrum distance of the transverse steel bar is small so that oversize bending deformation and rotation can be prevented.
Description
Technical field
The utility model relates to a kind of shearing resistance test fixture, belongs to building materials performance test apparatus technical field.
Background technology
In order to guarantee the physical strength of buildings, need to test to the shearing resistance of welded steel fabric solder joint; The common method of inspection is to randomly draw two to be the integrally welded reinforcing bar sample of decussation, and the transverse ends of fixing reinforcing bar sample, then applies test force to longitudinal end of reinforcing bar sample, to check its shearing resistance.Shearing resistance test fixture of the prior art exists test force easily to depart from tension reinforcement axis direction, is difficult to guarantee that sample and fixture are on same axis; And tension reinforcement free end cannot slide along axis direction, therefore cannot correct the skew of reinforcing bar sample; In test process, reinforcing bar sample easily produces excessive flexural deformation and rotation in addition.
Utility model content
The deficiency that the utility model exists for prior art just, provides a kind of shearing resistance test fixture, and test force is difficult for departing from tension reinforcement axis direction, can guarantee that sample and fixture are on same axis; And tension reinforcement free end can slide along axis direction, so movement among a small circle can be corrected the skew of reinforcing bar sample; In test process, reinforcing bar sample can not produce excessive flexural deformation and rotation in addition.
For addressing the above problem, technical solution adopted in the utility model is as follows:
A kind of shearing resistance test fixture, comprise: linking arm, fixed block, limited block, described fixed block one end is fixedly arranged on the bottom of described linking arm, and the described fixed block other end is provided with described limited block, and described limited block is two and is fixedly arranged on the both sides of described fixed block.
As the improvement of technique scheme, described linking arm, described fixed block, described limited block are cuboid, and described limited block bottom level is consistent with described fixed block bottom level, and described limited block overhead height is consistent with described linking arm overhead height.
As the improvement of technique scheme, described linking arm is fixedly connected with by bolt one with described fixed block, and described bolt one is two, and two described bolts one distribute side by side along the direction of shearing resistance test force.Described structure is easy to processing and assembling, and can guarantee the steadiness of shearing resistance test fixture in test process.
As the improvement of technique scheme, described limited block is fixedly arranged on the both sides of described fixed block by bolt two, and described bolt two is two, and two described bolts two distribute side by side along the direction of shearing resistance test force.Described structure is easy to processing and assembling, and can guarantee the steadiness of shearing resistance test fixture in test process.
Compared with prior art, implementation result of the present utility model is as follows for the utility model:
Shearing resistance test fixture described in the utility model, applies power along tension reinforcement axis, can guarantee that reinforcing bar sample and fixture are on same axis; And tension reinforcement free end can slide along axis direction, its movement among a small circle can be corrected skew; Suitably fixing to sample transverse steel in addition, transverse steel length of support is little, can prevent that it from producing excessive flexural deformation and rotation.In addition, intensity is high, the distortion of the test that do not exert an influence within the scope of a constant load; Temperature, humidity requirement are low, can meet all kinds of experimental enviroments.Through practice, confirm there is the ability of carrying out reliable test under multiple testing machine condition.
