Description

Technical Field

[0001] The utility model relates to the technical field of material test auxiliary tools, in particular to a mortar transverse deformation test workbench. Background Art

[0002] At present, the lateral deformation of construction adhesive refers to the maximum displacement of the hardened strip adhesive specimen when a crack appears in the center of the specimen when it is subjected to three-point bending. This parameter is a technical indicator to measure the quality of adhesives and is also a supplement to the rigidity test of adhesives. Mortar is a bonding material used in construction implementation.

[0003] Before a single experiment, the staff is required to re-determine the preset test position, that is, the staff is required to readjust the center position of the test piece before a single test. Since there is a certain error rate in the manual placement of the test piece, the reproducibility of the test data is affected. In addition, determining the preset test position before each test is time-consuming and labor-intensive, which affects work efficiency.

[0004] Therefore, it is necessary to design a mortar lateral deformation test bench that is practical and can accurately place specimens. Utility Model Content

[0011] Compared with the prior art, the beneficial effects achieved by the utility model are as follows: the utility model is provided with a workbench, and the hydraulic press on the workbench is electrically connected to an external power supply. When the staff starts the hydraulic press, the hydraulic press controls the hydraulic rod to extend, so that the hydraulic rod squeezes the mortar specimen. The fixed frame itself is a circular frame structure. The baffle and the clamping plate can limit the two sides of the mortar specimen respectively. When the staff tightens the clamping bolt, the clamping bolt approaches the baffle and moves into the positioning hole, thereby completing the positioning of the mortar specimen.

The baffle and the clamp are set in the fixed frame to limit the mortar specimen, and the mortar specimen is fixed by the combination of the clamping bolts and the positioning holes, which makes the placement of the mortar specimen more convenient and reduces the error in placing the mortar specimen. By setting a fixed block, when the mortar specimen is subjected to the force applied by the hydraulic rod and undergoes lateral deformation, the fixed block will be pushed to move. The fixed block drives the bottom plate to move through the vertical plate. The distance the bottom plate moves can be observed through the scale line to know the degree of lateral deformation of the mortar specimen.

[0012] The reinforcement rods used can support and fix the fixed frame to prevent the hydraulic rod from pushing the fixed frame when pushing the mortar specimen.

[0013] The sliding groove used is located below the mortar specimen. The mortar specimen will generate debris during the test. When the staff pulls out the sliding plate from one side of the sliding groove, the debris in the fixed frame will fall into the sliding groove and fall onto the collecting plate through the through hole and the discharge hole. The lower surface of the collecting plate is inclined to facilitate the collection of the debris.

[0014] The display pointer and scale bar are located on the same side, making it easier for staff to read.

[0015] The reinforcement plates used can support the vertical plates and prevent them from bending. BRIEF DESCRIPTION OF THE DRAWINGS
