Technical Field

[0001] This utility model belongs to the technical field of building testing equipment, specifically relating to a detachable thermal insulation board and base layer tensile bond strength testing device. Background Technology

[0002] Currently, in the construction industry, electric bonding strength testers are commonly used to test the tensile bond strength between insulation boards and the substrate.

[0003] Existing electric bonding strength testers are usually integrated structures. For example, Chinese utility model patent document CN212255033U discloses an electric bonding strength tester, which includes a box body with two support plates on both sides. During testing, the ends of the support plates abut against the insulation board, and the drive mechanism inside the box body drives the lead screw to move up and down to perform a pull-out strength test on the test block. The support plates and the box body are an integrated structure, and the setting of the support plates makes the device quite tall, requiring a large amount of three-dimensional space when not in use.

[0004] Therefore, it is necessary to design a detachable insulation board and base layer tensile bond strength testing device with detachable branch plates, which can be disassembled to store the box body and the branch plates separately, thereby reducing the three-dimensional space occupation, in order to solve the current technical problems. Summary of the Invention
