Description

Technical Field

[0001] The utility model relates to the field of pull-out force detection fixture equipment, and more specifically, particularly relates to a multifunctional anchor bolt pulling fixture. Background Art

[0002] The stress of the insulation anchor bolts is transmitted longitudinally on the insulation board after anchoring. If the tensile bearing capacity of the insulation anchor bolts does not meet the design requirements, the instability of the relevant nodes of the insulation board will cause the insulation board to fall off. The on-site test of the bearing performance of insulation anchor bolts for exterior wall insulation materials is an important part of the inspection of insulation and energy-saving projects. After the construction is completed, the tensile bearing capacity of the insulation anchor bolts must be randomly selected and re-tested to check whether it meets the requirements.

[0003] There are two main methods for on-site tensile bearing capacity test of thermal insulation anchor bolts. One is that a rivet puller loads the thermal insulation anchor bolts to the designed pre-tension value through a universal joint; the other is to use a bond strength tester in conjunction with a standard block to measure the peak bearing capacity of the anchor bolts. However, the existing fixture usage scenarios are relatively single, and operators need to prepare rivet boxes and standard blocks to switch between different testing equipment. When the number of samples is large, a large number of standard blocks need to be prepared, which is not only inconvenient for testers to carry, resulting in low equipment utilization, but also causing waste of manpower and material resources. Currently, there are no accessories that can adapt to both types of tensile test equipment at the same time. Utility Model Content

[0028] Example

[0029] Figure 1-3 The embodiment of the present application shown provides a multifunctional anchor bolt pulling clamp. In actual application, the anchor bolt pulling clamp is installed on the joint of a rivet puller or a bonding strength tester to measure the peak bearing capacity of the anchor bolt or to detect whether the tensile bearing capacity of the anchor bolt meets the design requirements. The multifunctional anchor bolt pulling clamp includes: a rivet box body 1 and a multifunctional joint 2.

[0030] See also Figure 1 The rivet box body 1 is a rectangular box-shaped structure with an opening on the side, which includes: an upper plate 11, a lower plate 12 and two side plates 13; the design of the side opening is convenient for the test personnel to adjust the position of the anchor bolt before pulling, and the pulling condition of the anchor bolt in the box can also be observed through the opening.

[0031] See also Figure 2 In the above technical solution, a notch 121 is provided at a position on the lower plate 12 corresponding to the multifunctional joint 2; the notch 121 is of a U-shaped structure, which is opened in the middle position of the lower plate 12, and the opening of the notch 121 extends to the edge of the lower plate 12. With this design, the anchor bolt can be conveniently inserted into the notch 121 along the opening when fixing the anchor bolt; it can be understood that the inner surface of the notch 121 is inclined so that the opening width of the upper edge of the notch 121 is greater than the opening width of the lower edge thereof; with this design, the opening of the notch 121 is in a jaw shape, which is adapted to the lower surface of the anchor plate of the thermal insulation anchor bolt, so that the lower plate 12 is more easily inserted into the gap between the anchor bolt and the thermal insulation board.

[0032] As a preferred implementation of this application, please refer to Figure 3 , support plates 131 are respectively provided at the lower ends of the two side plates 13, the two support plates 131 are arranged opposite to each other and parallel to the upper plate 11, and a gap for accommodating the lower plate 12 is formed between the two support plates 131; the two sides of the lower plate 12 are respectively provided with card grooves 122 that match the shape and size of the support plates 131, the lower plate 12 is placed on the support plates 131, and the support plates 131 are card-engaged in the card grooves 122; corresponding threaded holes are respectively provided on the lower plate 12 and the support plates 131, and fastening screws are connected to the threads in the threaded holes, so that the lower plate 12 can be detachably connected to the upper side of the support plate 131 ; After installation, the lower surface of the lower plate 12 is connected to the lower surface of the support plate 131 to form a smooth plane; after the clamp in the prior art has been used for a long time, the contact part between the clamp and the anchor bolt may be worn, resulting in loose clamping, and the existing clamp is an integral structure. After wear occurs, the entire clamp can only be replaced, and the cost of use is high; by adopting the above technical solution, after the clamp is partially worn, only the lower plate 12 needs to be replaced, and the lower plate 12 with slots 121 of different widths can be processed according to actual conditions, so that it is suitable for pull-out tests of anchor bolts of different specifications.

[0033] Furthermore, the multifunctional joint 2 is in the form of a sleeve structure as a whole, which is fixed on the surface of the upper plate 11 and located on the outside of the rivet box 1; the axis of the multifunctional joint 2 and the arc center of the slot 121 are located on the same straight line and are perpendicular to the upper plate 11 and the lower plate 12. With this design, when conducting the test, the direction of applying the pulling force and the anchor bolt are also kept on the same straight line, and the anchor bolt is evenly stressed, which can ensure the accuracy of the test results; the outer surface and inner wall of the multifunctional joint 2 are both provided with threads. With this technical solution, the multifunctional joint 2 can be connected to the rivet puller through the threaded connection on its outer surface to detect the stability of the anchor bolt under the preset tension value, and can also be connected to the bond strength tester through the threaded connection on its inner wall to measure the peak bearing capacity of the anchor bolt; the technical problem of the single usage scenario of the existing clamp is solved, and the utilization rate of the clamp is improved.

[0034] According to JG / T366-2012 Anchor Bolts for External Wall Insulation, the prestress of the tensile bearing capacity of the anchor bolt reaches (0.1kN~6.0kN)NRk1, NRk1 is the tensile bearing capacity, and the anchor bolt pulling fixture is required to be stably fixed on the joint of the pulling equipment, and the sensor force value must meet the requirement before the test can be carried out; in the multifunctional anchor bolt pulling fixture provided by the present application, the lower plate 12 cooperates with the support plate 131 to make the lower surface of the rivet box body 1 a flat plane, which can be attached to the surface of the external wall or the insulation material during detection, so that the pulling force of the pulling equipment is applied in the vertical direction of the anchor bolt, thereby ensuring the accuracy of the test result; the present application reduces the replacement cost of the fixture after damage by adopting a detachable lower plate 12, and can also be used for pulling anchor bolts of different specifications; the design of the multifunctional joint 2 enables the fixture to be installed on different equipment to complete different types of anchor bolt pulling detection tasks, thereby improving the portability and utilization rate of the fixture.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
