Concrete impact resistance test device

Abstract

The invention discloses a concrete impact resistance test device, which relates to the technical field of building test equipment. The right side wall of the moving plate is connected with the impact head; the right end of the guide column is fixed to the inner wall of the right side of the impact box. The extrusion spring sleeves the outer side of the guide column, the guide block is arranged in a groove in the left side of the moving plate, and the driving mechanism is connected with the guide block; the rotating plate is arranged on the upper side of the bottom plate; the lifting mechanism is arranged between the rotating plate and the adjusting plate; the upper side of the supporting plate is rotationally connected with the front and rear sides of the rotating plate; the rear end of the rotating rod is fixedly connected with an output shaft of the rotating motor; the front and rear ends of the rotating rod are rotationally connected with the upper surface of the bottom plate; the right ends of the rotating sleeves are fixed at the front and rear ends of the left side of the rotating rod outer ring wall; the rotating insertion rod is inserted into the two rotating sleeves, and the two supporting sheets are screwed with the left end of the rotating insertion rod through the bolts, so that the test device can be moved to a construction site, the concrete member does not need to be moved, the detection result is not influenced, and the test accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of construction test equipment, in particular to a concrete impact resistance test device. Background technique [0002] Concrete refers to the collective name of engineering composite materials in which aggregates are cemented into a whole by cementitious materials. When concrete is made into blocks, not only the compressive strength of concrete needs to be tested, but also the impact resistance of concrete needs to be tested. , so as to determine the impact resistance of concrete and determine the scope of use of concrete. At present, most of the impact resistance tests of concrete are realized by drop hammer impact testing machines. As we all know, the overall volume of drop hammer impact testing machines is relatively large. It is very inconvenient to move, so the drop hammer impact testing machine can only be used in a laboratory environment. The current method is to transport the concrete test block to...

[0002] Concrete refers to the collective name of engineering composite materials in which aggregates are cemented into a whole by cementitious materials. When concrete is made into blocks, not only the compressive strength of concrete needs to be tested, but also the impact resistance of concrete needs to be tested. , so as to determine the impact resistance of concrete and determine the scope of use of concrete. At present, most of the impact resistance tests of concrete are realized by drop hammer impact testing machines. As we all know, the overall volume of drop hammer impact testing machines is relatively large. It is very inconvenient to move, so the drop hammer impact testing machine can only be used in a laboratory environment. The current method is to transport the concrete test block to a laboratory with a drop hammer impact testing machine for operation. However, Concrete test blocks are often formed in an ideal environment, and there are often certain differences between them and the concrete components on the construction site, which will affect the test results
