[0002] Plastering mortar is a general term for a type of mortar that is applied to the building base for leveling or protection. Depending on the operation, plastering mortar is divided into on-site mixed mortar and premixed dry powder plastering mortar. Premixed dry powder plastering mortar is a type of commercial mortar. As to whether the plastering mortar meets the use requirements, the pull-out strength is an important property of the plastering mortar. The pull-out strength of the mortar needs to be tested before use.

[0003] The following problems are prone to occur during the use of the mortar pull-out strength measuring device. First, when applying tension in the mortar pull-out strength test, there is no guide device when the connecting rod moves, which makes the connecting rod easy to shake left and right and cause deviations when moving, thereby reducing the accuracy of the test results. Second, at the moment when the test mortar block is separated from the standard block, gravel is easy to fall on the test bench at the connection between the test mortar block and the standard block. Due to the lack of a cleaning device, the test bench cannot be cleaned in time, which affects the next experiment. Therefore, in response to the above problems, we proposed a mortar pull-out strength measuring device. Utility Model Content
