Description

Technical Field

[0001] This utility model relates to the technical field of foundation testing equipment, and in particular to a foundation tensile bearing capacity testing device. Background Technology

[0002] Currently, various testing methods are often used during the construction process to test the structural strength of buildings. Among them, the testing of the tensile bearing capacity of the foundation is particularly important, as it is closely related to the overall tensile performance of the building structure.

[0003] A search revealed that the utility model patent with authorization announcement number CN216718007U discloses a foundation pull-out bearing capacity testing device. By having a limiting block of the traction rod pass through a rectangular hole in a fixed column, the traction rod is rotated so that the limiting block intersects with the rectangular hole, thus achieving a detachable connection between the traction rod and the pull plate. By pushing the traction rod downward and rotating it, the traction rod is separated from the pull plate, which facilitates the grinding and removal of the weld points on the traction rod and allows for the reuse of the traction rod.

[0004] Although the above-mentioned device can test the tensile bearing capacity of the foundation, it requires one-by-one operation when disassembling multiple traction rods, which consumes a lot of manpower and time to complete the disassembly of multiple traction rods, making it inconvenient in actual use.

[0005] Therefore, it is necessary to invent a foundation pull-out bearing capacity testing device to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a foundation tensile bearing capacity testing device that can simultaneously complete the disassembly of multiple traction rods, saving manpower and improving disassembly efficiency. It is more convenient in actual use, thus solving the problem mentioned in the background art that when existing equipment disassembles multiple traction rods, it is necessary to operate them one by one, which requires a lot of manpower and time to complete the disassembly of multiple traction rods and is not convenient in actual use.

[0007] According to one aspect of this disclosure, the following technical solution is provided: a foundation tensile bearing capacity testing device, comprising:

[0008] A pulling mechanism for lifting the mounting mechanism;

[0009] The mounting mechanism includes a mounting plate fixedly disposed at the bottom of the column and a rotating plate rotatably sleeved on the outer bottom end of the column via bearings. The mounting plate has multiple evenly spaced limiting channels on its outer side, and the rotating plate has multiple staggered limiting grooves and pushing inclined surfaces on its top. The limiting grooves are semi-circular.

[0010] A traction connection mechanism is used to connect with the reinforcing bars of the cast-in-place pile.

[0011] According to at least one embodiment of the foundation pull-out bearing capacity testing device of the present disclosure, the traction connection mechanism further includes a locking hole opened on the top of the mounting plate and the rotating plate, and a locking pin is inserted into the inner side of the locking hole.

[0012] According to at least one embodiment of the foundation pull-out bearing capacity testing device of the present disclosure, the pull-out mechanism includes a crossbeam, and a plurality of hydraulic cylinders are fixedly disposed on the top of the crossbeam.

[0013] According to at least one embodiment of the foundation pull-out bearing capacity testing device of the present disclosure, a top plate is fixedly provided at the top of the output shaft of a plurality of hydraulic cylinders, a bottom plate is provided below the crossbeam, a plurality of connecting rods are fixedly provided between the top plate and the bottom plate, and a column is fixedly provided at the center of the bottom of the bottom plate.

[0014] According to at least one embodiment of the foundation pull-out bearing capacity testing device of the present disclosure, the traction connection mechanism includes a plurality of traction rods, and any one of the traction rods is slidably disposed in the vertical direction inside the adjacent limiting channel and limiting groove.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] This invention features a mounting mechanism that allows the limiting channels and adjacent limiting grooves to restrict the traction rods during the testing process, preventing them from detaching. When removing multiple traction rods, the welding between the locking pin and the reinforcing bar is first released. Then, the locking pin is pulled upwards from the inside of the locking hole. Next, the rotating disk is rotated clockwise, causing the limiting portion of the traction rod at the top of the mounting disk to gradually move out of the adjacent limiting groove to release the restriction. As the rotating disk continues to rotate, the inclined plane pushes the limiting portions of adjacent traction rods until multiple traction rods simultaneously fall from the inside of multiple limiting channels. Compared to existing technologies, this invention can simultaneously complete the disassembly of multiple traction rods, saving manpower and improving disassembly efficiency, making it more convenient in actual use.

[0017] The accompanying drawings illustrate exemplary embodiments of the present disclosure and, together with the description thereof, serve to explain the principles of the present disclosure. These drawings are included to provide a further understanding of the present disclosure and are incorporated in and constitute a part of this specification.

[0025] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0026] Figure 1 This is a schematic diagram of the overall structure of a foundation tensile bearing capacity testing device according to one embodiment of the present disclosure.

[0027] Figure 2 This is a schematic diagram of the pull-out mechanism 1 of a foundation pull-out bearing capacity testing device according to one embodiment of the present disclosure.

[0028] Figure 3 This is a schematic diagram of the mounting mechanism 2 and the traction connection mechanism 3 of a foundation pull-out bearing capacity testing device according to one embodiment of the present disclosure.

[0029] like Figures 1-3As shown, the foundation pull-out bearing capacity testing device disclosed herein may include components such as a pull-out mechanism 1, a mounting mechanism 2, and a traction connection mechanism 3.

[0030] like Figure 2 As shown in this disclosure, the pulling mechanism 1 includes a crossbeam 11, a plurality of hydraulic cylinders 12 are fixedly installed on the top of the crossbeam 11, a top plate 13 is fixedly installed on the top of the output shaft of the plurality of hydraulic cylinders 12, a bottom plate 14 is installed below the crossbeam 11, a plurality of connecting rods 15 are fixedly installed between the top plate 13 and the bottom plate 14, and a column 16 is fixedly installed at the center of the bottom of the bottom plate 14.

[0031] This allows the two ends of the crossbeam 11 to be raised and form a stable support. Then, the traction connection mechanism 3 is welded and fixed to the reinforcing bar. At this time, the hydraulic cylinder 12 drives the top plate 13 to move upward. When the top plate 13 moves upward, it drives the bottom plate 14 to move upward through the connecting rod 15. When the bottom plate 14 moves upward, it drives the mounting mechanism 2 to move upward through the column 16. Then, the mounting mechanism 2 pulls the reinforcing bar through the traction connection mechanism 3.

[0032] like Figure 3 As shown, in a preferred embodiment, the mounting mechanism 2 includes a mounting plate 21 fixedly disposed at the bottom of the column 16 and a rotating plate 23 rotatably sleeved on the outer bottom end of the column 16 via a bearing. The mounting plate 21 has a plurality of limiting channels 22 evenly distributed on its outer side. The rotating plate 23 has a plurality of limiting grooves 24 and a pushing slope 25 staggeredly distributed on its top. The limiting grooves 24 are semi-circular. The traction connection mechanism 3 also includes a locking hole 26 opened on the top of the mounting plate 21 and the rotating plate 23. A locking pin 27 is inserted into the inner side of the locking hole 26.

[0033] Therefore, during the testing process, the limiting channel 22 and the adjacent limiting groove 24 limit the traction rod 31, preventing it from coming off. When removing multiple traction rods 31, first, the welding between the locking pin 27 and the reinforcing bar is released. Then, the locking pin 27 is pulled upward from the inside of the locking hole 26. Subsequently, the rotating disk 23 is rotated clockwise, causing the limiting part of the traction rod 31 located at the top of the mounting plate 21 to gradually move out from the inside of the adjacent limiting groove 24 to release the limitation. As the rotating disk 23 continues to rotate, the inclined surface 25 pushes the limiting part of the adjacent traction rod 31 until multiple traction rods 31 fall out from the inside of multiple limiting channels 22 at the same time. Compared with the existing technology, the disassembly of multiple traction rods 31 can be completed simultaneously, saving manpower and improving disassembly efficiency, making it more convenient in actual use.

[0034] like Figure 3 As shown in this disclosure, the traction connection mechanism 3 includes a plurality of traction rods 31, and any one of the traction rods 31 is slidably disposed in the vertical direction inside the adjacent limiting channel 22 and the limiting groove 24.

[0035] Therefore, before the test begins, multiple traction rods 31 are welded and fixed to multiple steel bars. When the pulling mechanism 1 drives the mounting mechanism 2 to move upward, the mounting mechanism 2 pulls multiple steel bars through multiple traction rods 31, thereby realizing the pull-out bearing capacity test.

[0036] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0037] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
