Description

Technical Field

[0001] The utility model relates to the field of tensile bonding strength test of self-leveling mortar, in particular to a clamp used for tensile bonding strength test of self-leveling mortar. Background Art

[0002] Patent No. CN205394785U discloses a detachable building mortar tensile bond strength test molding die. The utility model has a reasonable structural design. Since each component is detachable and replaceable, the use cost is reduced and the service life is extended.

[0003] However, the above-mentioned existing detachable building mortar tensile bond strength test molding mold is connected by clamping the stainless steel strip into the slot of the strip. Since the device is fixed by artificial clamping, when the mortar is poured in during use, it is easy to flow out through the clamping gap, which is not convenient for shaping and fixing the mortar. When the shape changes, it is easy to cause deviations in the test results.

[0004] In order to solve the above problems, the utility model provides a fixture for tensile bonding strength test of self-leveling mortar. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a clamp for tensile bond strength testing of self-leveling mortar to solve the technical problem in the prior art that "a stainless steel strip is connected by being clamped into a slot of a long strip. Since the device is fixed by manual clamping, when the mortar is poured in during use, it is easy to flow out through the clamping gap, which is not convenient for shaping and fixing the mortar. When the shape changes, it is easy to cause deviations in the test results."

[0009] As a preferred technical solution of the utility model, the top end of the spring is fixedly connected to a limiting block, and the surface of the limiting block is slidably connected in the sliding groove and the groove at the same time.

[0010] As a preferred technical solution of the present utility model, one side opposite to the first clamping frame and the second clamping frame is configured in a sawtooth shape.

[0011] As a preferred technical solution of the present utility model, the first clamping frame and the second clamping frame match each other.

At the same time, by setting the sawtooth shape, the first clamping frame and the second clamping frame can fit more completely;

[0014] 2. The bidirectional threaded rod can drive the first clamping frame and the second clamping frame to move at a relative uniform speed. At the same time, the base can be used to place the mortar completely on the base during demolding to avoid deformation of the mortar during demolding. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following is a further detailed description of the implementation of the present utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0022] refer to Figure 1-4 The utility model provides a technical solution: a clamp for tensile bonding strength test of self-leveling mortar, including a workbench 1, the upper end surface of the workbench 1 is symmetrically fixedly connected with a first connecting plate 2 on both sides, and the first connecting plate 2 is rotatably connected with a bidirectional threaded rod 3 on one side opposite to the first connecting plate 2. By setting the bidirectional threaded rod 3, the first clamping frame 7 and the second clamping frame 8 can be driven to move at a relatively uniform speed. The surface of the bidirectional threaded rod 3 passes through the side wall of one of the first connecting plates 2 and is fixedly connected with a handle 4. By setting the handle 4, the bidirectional threaded rod 3 can be conveniently adjusted. The groove rod 3 rotates, and the second connecting plates 12 are symmetrically fixedly connected on both sides of the upper end surface of the workbench 1, and the limiting rod 6 is fixedly connected on the opposite side of the second connecting plate 12. The first clamping frame 7 and the second clamping frame 8 are slidably connected to the upper end surface of the workbench 1. A groove 13 is provided on the upper end surface of the workbench 1, and a base 10 is fixedly connected in the groove 13. Slide grooves 14 are provided on both sides of the base 10, and a spring 15 is fixedly connected in the slide groove 14. By setting the spring 15, the elasticity of the spring 15 can be used to drive the limit block 11 to be squeezed and reset.

[0023] The front sides of the first clamping frame 7 and the second clamping frame 8 are both provided with threaded holes 5 , and the surfaces of the bidirectional threaded rod 3 are threadedly connected with the first clamping frame 7 and the second clamping frame 8 in the two threaded holes 5 .

[0024] The front sides of the first clamping frame 7 and the second clamping frame 8 are both provided with through holes 9 , and the surface of the limiting rod 6 is slidably connected with the first clamping frame 7 and the second clamping frame 8 through the through holes 9 .

[0025] The top end of the spring 15 is fixedly connected to the limiting block 11 , and the surface of the limiting block 11 is slidably connected in the sliding groove 14 and the groove 13 at the same time.

[0026] The opposite side of the first clamping frame 7 and the second clamping frame 8 is configured to be serrated. By configuring the serrated shape, the first clamping frame 7 and the second clamping frame 8 can be more closely fitted together, thereby reducing the generation of gaps.

[0027] The first clamping frame 7 and the second clamping frame 8 match each other.

[0028] The working principle of the utility model is as follows: by rotating the handle 4, the bidirectional threaded rod 3 is driven to rotate, so that the first clamping frame 7 and the second clamping frame 8 are moved toward a relative position. When they move to the limit block 11, the surface of the limit block 11 is squeezed, driving the spring 15 to squeeze, and driving the limit block 11 to move downward. When the first clamping frame 7 and the second clamping frame 8 are in contact, the squeezing of the limit block 11 is cancelled, and the spring 15 drives the limit block 11 to reset, so that the limit block 11 limits the position of the first clamping frame 7 and the second clamping frame 8, so that the first clamping frame 7, the second clamping frame 8 and the base 10 are completely in contact, and then the self-leveling mortar can be poured into the first clamping frame 7 and the second clamping frame 8.

[0029] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and utility model concept of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model.
