Description

Technical Field

[0001] The utility model relates to the field of wall performance detection, in particular to a portable test device for detecting the impact resistance of a wall. Background Art

[0002] At present, there are two main test methods for the impact resistance of walls, one is the "drop hammer test method" and the other is the "pendulum test method". Among them, the drop hammer test method is the most widely used in the impact resistance test of walls in my country. Due to the simple test principle of the drop hammer test, many laboratories do not have relevant professional test equipment. Usually, the reaction frame already available in the laboratory is used instead for the test. However, the reaction frames already available in the laboratory are generally fixed in position, and are mostly equipped with relevant experimental instruments. In order to meet the conditions for the impact resistance test, the reaction frame must first be modified, and the wall to be tested must be hoisted to the position of the reaction frame. The operation is complicated and cumbersome, time-consuming and labor-intensive. Utility Model Content
