A support shear differential compensation connection device

Abstract

The invention relates to a shearing resistant difference-supplementing connecting device for a support, and belongs to a structure experiment technology. The shearing resistant difference-supplementing connecting device for the support comprises a shearing slide plate 1, propping and fixing bolts 2, anchor plate bolts 3, anchor plates 4, difference-supplementing plates 5, difference-supplementing bolts 6, a dovetail groove 7, and anchor bolt holes 8, wherein the two anchor plates are paved on the shearing slide plate 1 with the uniformly distributed anchor bolt holes 8, and are fixed on the shearing slide plate 1 through the anchor plate bolts 3; each difference-supplementing plate 5 is placed between each anchor plate and the support 9 to be detected; threaded through holes are formed in the anchor plates in the shearing direction; the propping and fixing bolts are screwed inwards through the threaded through holes to be propped against the difference-supplementing plates, so that shearing counter force can be provided for the test of the support 9. According to the invention, the anchor plates and the difference-supplementing plates are placed on the shearing slide plate, so that the repeated processing of a connecting plate can be avoided, further, the test cycle and test cost can be reduced, the safety of the personnel and equipment can be guaranteed, and the accuracy and integrity of the testing result can be ensured.

Description

Technical field: [0001] The invention relates to a support shear differential compensation connection device, which is used for fixing the support in the shear direction in the support shear test and providing the reaction force required by the shear test. Background technique: [0002] In the shear test of the support, it is often connected with the shear slide plate by connecting bolts through the mounting holes of the connecting plate of the support itself. Due to the variety of support types, the diameter and hole position of the mounting holes are even more diverse. For each type of support, a transition connection plate matching the mounting hole must be processed, which greatly lengthens the test cycle and increases the test cost. ; Since the diameter of the connecting bolt is smaller than the diameter of the mounting hole, and the shear force in the test is often greater than the friction between the support and the transition plate, the transition plate and the shea...

Problems solved by technology

Due to the variety of support types, the diameter and hole position of the mounting holes are even more diverse. For each type of support, a transition connection plate matching the mounting hole must be processed, which greatly lengthens the test cycle and increases the test cost. ; Since the diameter of the connecting bolt is smaller than the diameter of the mounting hole, and the shear force in the test is often greater than the friction between the support and the transition plate, the transition plate and the shear slide plate, once the relative slip occurs between the friction surfaces, the connection The impact shear of the bolts is easy to cut the bolts, causing potential safety hazards for equipment and personnel. Second, it affects the test results, causing flaws or even failures in the test results.
