Description

Technical Field

[0001] The utility model belongs to the technical field of bearing capacity detection, in particular to an auxiliary tooling for detecting the bearing capacity of oblique rebar planting. Background Art

[0002] Oblique anchoring is a commonly used reinforcement method in reinforced concrete structures. During the construction process, a certain number of steel bars are placed in the concrete components to enhance their bending and shear resistance, thereby improving the stability and bearing capacity of the entire structure. Oblique anchoring refers to burying the steel bars obliquely into the concrete at a certain angle, so that the adhesion between the steel bars and the concrete is stronger, thereby improving the bearing capacity of the concrete. This reinforcement method is usually used on components such as walls, columns, and beams. During the construction process, first of all, it is necessary to reserve the position of the reinforcing steel bars, and ensure that the length and spacing of the steel bars meet the design requirements. Then, the steel bars are inserted obliquely into the concrete at the specified angle, and then the concrete is poured into the construction formwork. When the concrete is vibrated and compacted, the steel bars will be firmly clamped inside the concrete to form a solid structure.

[0003] When performing pull-out tests on oblique embedded rebars, since the oblique embedded rebars have a certain inclination angle, the device cannot provide sufficient support for the testing equipment during installation, which may affect the accuracy and stability of the test results. For example, when the testing equipment cannot fully fit the oblique embedded rebars, the equipment will shake or shift, making it impossible to obtain accurate pull-out force data. At the same time, the inclination angle of the oblique embedded rebars may also affect the use angle and direction of the testing equipment, making the testing process more complicated and difficult.
