Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment technology for anchor bolt pull-out testing, and particularly to anchor bolt pull-out testing connection components, devices, and performance testing systems. Background Technology

[0002] In current methods, the anchor pull-out test, mainly referring to the foundation pit anchor test, is an engineering test that uses a loading device to pull out the anchor and measure the displacement of the anchor head to evaluate its pull-out bearing capacity and anchoring performance reliability. The basic test uses the multi-cycle loading method to determine the ultimate pull-out bearing capacity. It is mainly used to evaluate the pull-out bearing capacity of the anchor in rock or soil and the reliability of its anchoring performance. Its quality is directly related to the safety of the project.

[0003] The basic test is used to determine the ultimate pull-out bearing capacity of the anchor bolt, the characteristic value or standard value of the bond strength between the anchor body and the soil layer, and to verify the rationality of the anchor bolt design parameters. The core principle of the anchor bolt pull-out test is the balance of action and reaction forces. During the test, an axial tensile force is applied to the anchor bolt through a loading system. This tensile force is balanced by the bond friction between the anchor bolt anchor section and the surrounding soil. The load and displacement changes are recorded by measuring equipment. The anchor bolt pull-out test system mainly consists of a large-tonnage hydraulic jack, a high-pressure oil pump, and a manual or servo control valve group, which is used to apply axial tensile force to the anchor bolt. The reaction device usually adopts a rigid reaction frame or reaction ring. Anchor pull-out tests are widely used in slope protection, deep foundation pit engineering, tunnel and underground cavern reinforcement, structural anti-buoyancy, and foundation anchoring of large structures. Specific applications include anchors for foundation pit support in building engineering, such as temporary soil anchors and permanent rock anchors for deep foundation pit retaining structures, as well as anchors in pile anchor systems, diaphragm wall anchor systems, and soil nailing walls and composite soil nailing walls. Currently, the main technical problem in existing technologies is that when anchor bolts are tested on inclined structures, existing reaction support components, such as reaction frames, reaction rings, and reaction plates, cannot be directly adapted to the inclined surface of the structure. This leads to the need to use pads during anchor bolt pull-out tests, or the use of reaction components directly in the test without proper rigor. This results in gaps between the reaction components and the inclined surface, causing uneven stress on the reaction components. Since the test requires a pressurization and pressure holding process, unstable reaction supports can easily damage the test quality. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

The purpose of such description is to clearly express the technical solution and should not be construed as an improper limitation of the technical solution of this application.

[0021] This invention addresses the technical problem in existing technologies involving horizontal anchor bolts on inclined surfaces, where the testing requires pressurization and pressure holding processes, and unstable reaction force supports easily lead to compromised testing quality. It provides anchor bolt pull-out test connection components, devices, and performance testing systems. Firstly, the application of this solution relies on the following... Figure 1 , 2 The anchor bolt pull-out test connection assembly specifically includes: The inclined main bonding plate 10 is used to bond to the inclined surface 4 of the structure 3 of the test anchor 1 as part of the actual reaction support surface. The inclined main bonding plate 10 has a through hole 101 through which the test anchor 1 passes. The reaction support plate 20 is arranged perpendicular to the foundation plane. The center of the reaction support plate 20 is provided with a through hole 210 through which the test anchor 1 passes and exits. It can be directly adapted to existing anchor testing equipment such as hollow jacks, hydraulic application systems and testing systems, so that the existing jack equipment can be perfectly adapted. The reaction support plate 20 is used to provide a regular vertical plane to deal with the influence of the slope 4. The slope main bonding plate 10 and the reaction support plate 20 are also provided with reinforced pressure-bearing components, specifically a reaction support column 30. The reaction support column 30 can be screwed to the end of the transverse fixing rod 501 of the adjusting hinge fixing support system 50. The reaction support column 30 is adjusted to fit against the reaction support plate 20 through the screw connection with the transverse fixing rod 501. The adjusting hinge fixing support system 50 and the tilt adjusting hinge 40 can adapt to the tilt angle of the inclined plane 4, adapting to various structures 3 with inclined plane 4 and test anchor rod 1. The adapted tilt angle can be varied, and a stable support can also be formed by adjusting the hinge fixing support system 50. Specifically, the tilt adjusting hinge 40 can rotate to connect the inclined plane main bonding plate 10 away from the inclined plane. On one side of the inclined plane 4, the tilt adjustment hinge 40 can connect two sets of balance bars 401, which are arranged in parallel. The balance bars 401 can be arranged in parallel with the transverse fixing bars 501. The adjustment hinge fixed support system 50 also includes two sets of longitudinal fixing bars 502, which are arranged in parallel and can be perpendicular to the transverse fixing bars 501. The longitudinal fixing bars 502, the transverse fixing bars 501, and the balance bars 401 form a fixed node, so that a stable support force system is formed between the inclined main bonding plate 10 and the reaction support plate 20 to cope with the force of the anchor pull-out test. The advantages of this technical solution are: This technical solution uses a sloping main bonding plate 10 to adapt to the sloping surface 4 of the structure 3. A stable support system is formed by adjusting the hinge fixing support system 50 and the tilt adjustment hinge 40. This support system has stable nodes. After the angle of the tilt adjustment hinge 40 is determined, multiple support nodes are formed by the transverse fixing rod 501, the balance rod 401, and the longitudinal fixing rod 502, so that the hinge structure is stable. With the cooperation of the reaction support column 30, the force between the sloping main bonding plate 10 and the reaction support plate 20 can withstand the anchor pull-out test, so as to solve the stability of the test anchor 1 pull-out test on the sloping surface 4 of the structure 3.

A balance bar nut can be screwed onto the balance bar 401 to achieve locking. The balance bar connection 413 can have a horizontal state, which is pre-adjusted by the rotation angle between the hinge connection 412 and the hinge seat 411.

The configuration method is simple; please refer to the appendix for details. Figure 1 ,2 As shown, the method for adjusting the fixing of the hinge fixing support system 50 includes the following steps: Step S101: Place the inclined main bonding plate 10 against the inclined surface 4.
