The threaded rod 32 is threadedly connected to the inside of one end of the connecting frame 31. The clamping plate 34 is rotatably connected to one end of the threaded rod 32. The rotating handle 33 is fixedly installed at the other end of the threaded rod 32. The pad 35 is fixedly installed at the other end of the connecting frame 31.

[0022] The clamping plate 34 abuts against the side of the steel casing 2, and the pad 35 abuts against the side of the template 1.

[0023] The working principle of the mold for measuring the normal bond strength between a valve-type steel casing and concrete provided by this utility model is as follows: When using the equipment, first insert the anchoring steel bar 12 into the inner side of the through hole 11. Then, place the steel casing 2 on the side of the template 1, with one end of the anchoring steel bar 12 on the inner side of the steel casing 2. Next, set multiple clamps 3 on the outer sides of the steel casing 2 and the template 1, and then rotate the handle 33 to drive the threaded rod 32 to make a threaded connection inside the connecting frame 31. Then, move the clamping plate 34 to one side of the steel casing 2 to clamp and limit the steel casing 2 and the template 1. Then, pour concrete into the mold. After the curing period is reached, remove the template 1 and clamp the steel bar support 21 and the anchoring steel bar 12 into the clamps of the universal testing machine.

[0025] Example 2

[0026] Please refer to the following: Figure 3 and Figure 4 Based on the mold provided in the first embodiment of this application for measuring the normal bond strength between a valve-type steel casing and concrete, the second embodiment of this application proposes another mold for measuring the normal bond strength between a valve-type steel casing and concrete. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0027] Specifically, the difference in the mold for measuring the normal bond strength between the valve-type steel casing and concrete provided in the second embodiment of this application is that the mold for measuring the normal bond strength between the valve-type steel casing and concrete has insertion grooves 4 at both ends of both sides of the template 1.

[0028] The inner side of the insertion slot 4 is fitted with a insertion base 5, and a support frame 51 is fixedly installed on the side of the insertion base 5.

[0029] An adjusting rod 52 is internally threaded at one end of the support frame 51, and a support plate 53 is rotatably connected to the bottom of the adjusting rod 52.

[0030] The outer side of the adjusting rod 52 is threaded, which allows it to be threaded into the interior of the support frame 51 during use.

[0031] The working principle of the mold for measuring the normal bond strength between a valve-type steel casing and concrete provided by this utility model is as follows: After assembling the template 1 and the steel casing 2, the plug-in base 5 can be inserted into the inner side of the plug-in slot 4, thereby installing the four support frames 51 around the template 1 respectively. Then, the user rotates the adjusting rod 52 so that the adjusting rod 52 is threaded into the inside of one end of the support frame 51, and then drives the support plate 53 to move downward and contact the ground, thereby adjusting the level of the template 1 to prevent the template 1 from tilting.

[0032] Compared with related technologies, the mold provided by this utility model for measuring the normal bond strength between a valve-type steel casing and concrete has the following advantages: The interlocking groove 4, interlocking seat 5, support frame 51, adjusting rod 52 and support plate 53 work together to adjust the level of the template 1. When in use, the interlocking seat 5 is inserted into the inner side of the interlocking groove 4 to install the support frame 51. Then the adjusting rod 52 is threaded into the support frame 51. This allows for the adjustment of the template 1 to prevent the template 1 and steel casing 2 from tilting after concrete is poured, which would affect the solidification effect.
