[0002] Bonding mortar is a common building material, widely used in exterior wall insulation systems. It not only improves a building's thermal insulation performance but also ensures a reliable connection between the insulation board and the base wall, enhancing the wall's structural stability. Testing the tensile bond strength is a key indicator in exterior wall bonding mortar testing. Before testing, test specimens must be prepared according to standard requirements.

[0003] The current laboratory testing process involves placing a forming frame on the insulation board sample, adding the mixed bonding mortar into the frame, and smoothing the mortar with a spatula. Once the mortar has bonded to the upper surface of the insulation board sample, the forming frame is lifted, completing the preparation of a test sample.

[0047] Reference Figure 4 、 Figure 5 The limiting platform 5 is penetrated by a sample hole 51 for the insulation board sample to pass through, and the sample hole 51 is located directly below the forming hole 31. The upper end surface of the base 1 is provided with a lifting chamber 12 located directly below the sample hole 51. The base 1 is provided with a lifting platform 13 that is vertically slidably connected to the lifting chamber 12. The base 1 is provided with a control component 7 that controls the lifting and lowering of the lifting platform 13. The outer wall of the lifting platform 13 is provided with a limiting hole 131, and the inner wall of the lifting chamber 12 is provided with a locking chamber 14 corresponding to the limiting hole 131. The control component 7 includes a lifting spring 71 that is built into the lifting chamber 12 and forces the lifting platform 13 to rise under normal circumstances, a limiting block 72 that is slidably connected to the locking chamber 14 in a direction close to or away from the limiting hole 131 and is slidably inserted in the limiting hole 131, a limiting spring 74 that is built into the locking chamber 14 and normally forces the limiting block 72 to slide toward the limiting hole 131, and an unlocking rod 73 that is fixedly connected to the limiting block 72 and slides through the outer wall of the base 1.

[0048] The upper end of the lifting spring 71 is fixedly connected to the lower end surface of the lifting platform 13, and the lower end of the lifting spring 71 is fixedly connected to the bottom inner wall of the lifting chamber 12. The limit spring 74 is sleeved on the unlocking rod 73. One end of the limit spring 74 is fixedly connected to the end of the limit block 72 away from the lifting platform 13, and the other end of the limit spring 74 is fixedly connected to the inner wall of the locking chamber 14. The end of the limit block 72 near the lifting platform 13 has a guide surface that is used to force the limit block 72 to retract into the locking chamber 14 when the lower end surface of the lifting platform 13 abuts. The outer end of the unlocking rod 73 is fixedly connected to a force ring 75. In the initial state, the lifting platform 13 descends and retracts into the lifting chamber 12, the limit block 72 is inserted into the limit hole 131, the lifting spring 71 is in a compressed state, and the upper surface of the lifting platform 13 is flush with the upper end surface of the base 1.

[0049] The implementation principle of the embodiment of the present application is: the insulation board sample is passed through the forming hole 31 in the center of the forming platform 3 and the sample hole 51 in the center of the limit platform 5 from top to bottom, so that the insulation board sample is in contact with the upper surface of the lifting platform 13, and the first knob 42 and the second knob 62 are turned to make the upper part of the insulation board sample pass through the forming hole 31, and make the upper end surface of the insulation board sample not protrude from the upper end surface of the forming platform 3, so that a mortar cavity is formed between the upper end surface of the insulation board sample and the inner peripheral wall of the forming hole 31, and then the mixed bonding mortar is poured into the mortar cavity and the bonding mortar is smoothed with a shovel. After the mortar and the upper surface of the insulation board sample are formed, the unlocking rod 73 is pulled by the force ring 75 to drive the limit block When the lifting platform 13 is unlocked, the lifting spring 71 lifts the lifting platform 13, thereby driving the sample upward so that the upper part of the sample protrudes from the upper end surface of the forming platform 3, making it easier for the operator to remove the sample. The lifting platform 13 is then pressed. During the downward movement of the lifting platform 13, the bottom wall of the lifting platform 13 abuts against the guide surface of the limit block 72, forcing the limit block 72 to retract into the locking hole. At this time, the limit spring 74 undergoes elastic deformation and has elastic potential energy. When the position of the limit hole 131 corresponds to the position of the limit block 72, the limit spring 74 forces the limit block 72 to slide and be inserted into the limit hole 131, thereby fixing the lifting platform 13 and placing the next insulation board sample block to apply bonding mortar. In order to facilitate the demolding of the adhesive layer, an anti-sticking agent can be first applied to the inner wall of the forming hole 31.

[0050] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
