Description

Technical Field

[0001] This utility model relates to the field of experimental device technology, and in particular to a connecting component for a fixed anchoring section simulation structure. Background Technology

[0002] Anchors are key components in geotechnical and civil engineering, widely used in tunnel support, slope stabilization, deep foundation pit retaining walls, bridge anchorages, dam reinforcement, and other fields. Their core function is to distribute structural loads to deep, stable soil and rock layers through prestress transfer, preventing slippage, collapse, or deformation.

[0003] Traditional anchor tension tests are typically conducted on-site, but this method has several limitations. On-site testing conditions are complex, making precise control of test parameters difficult, and the tests are costly and time-consuming. To overcome these problems, researchers have begun using indoor testing equipment to conduct anchor tension tests. Currently, concrete beams are commonly used for anchor tension tests, where anchors are fixed in anchor holes within the concrete beam, and tension is applied to simulate the process. However, concrete beams are for single use, resulting in high costs and long fabrication times. Therefore, in non-public testing, such as... Figure 1 As shown, some technicians have designed a test frame and then installed a simulation tube 10 inside the test frame. The end of the simulation tube 10 is located outside the test frame, and the head of the simulation tube extends into the test frame. The simulation tube 10 is used as the anchor hole during the anchor test, that is, the simulation tube is used as the anchoring section during the simulation of the anchor. When a secondary test is required, the simulation tube 10 can be replaced. However, currently, the simulation tube 10 is generally welded to the test frame. Replacing the simulation tube requires secondary cutting, which is troublesome and inefficient. Utility Model Content

[0004] The purpose of this invention is to address the problem in the prior art that the simulated pipe is not stable when installed in the anchoring section module and is prone to shaking during the test, and to provide a connecting component for fixing the simulated anchoring section structure.

[0005] This utility model provides a connecting component for a fixed anchorage section simulation structure, including:

[0006] Experimental framework;

[0007] The base is installed inside the test frame;

[0008] A support tube is disposed on the base, and a support seat is connected to the end of the support tube away from the base. An inner groove is provided in the support seat, and the inner groove is used to abut against the head end of the simulation tube.

[0009] A baffle is used to be installed at the tail end of the simulation tube, and the baffle abuts against one end of the test frame.

[0010] Preferably, it further includes a sleeve connected to the base, and the support pipe is threaded onto the sleeve.

[0011] Preferably, the inner wall of the sleeve is provided with a first internal thread;

[0012] The outer wall of the support tube is provided with a first external thread that matches the first internal thread.

[0013] Preferably, the bottom of the inner groove is provided with a connecting hole, which penetrates the support base.

[0014] Preferably, the inner groove is a cylindrical groove;

[0015] The inner groove is coaxially arranged with the support tube.

[0016] Preferably, the inner diameter of the groove is larger than the outer diameter of the simulated tube;

[0017] Furthermore, the inner diameter of the connecting hole is smaller than the outer diameter of the simulated tube.

[0018] Preferably, the sleeve is a steel pipe.

[0019] Preferably, the support pipe is a steel pipe.

[0020] Preferably, the base is provided with a first through hole, which is coaxially arranged with the support tube.

[0021] Preferably, the base is provided with mounting plates on the upper and lower sides, and the mounting plates are used to connect with the test frame.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] This application discloses a connecting component for a fixed anchorage section simulation structure. A base is installed inside a test frame, and a support tube is mounted on the base. A support seat is connected to the support tube, and an inner groove is provided on the support seat. In actual use, the first end of the simulation tube extends into the test frame until it abuts against the bottom of the inner groove, thereby fixing and limiting the simulation tube within the test frame. This effectively prevents the simulation tube from shaking significantly during the test. Furthermore, a baffle is located at the tail end of the simulation tube, abutting against one end of the test frame, thus limiting the tail end of the simulation tube. This connecting component for a fixed anchorage section simulation structure can limit both ends of the simulation tube, thereby installing the simulation tube in the test frame. When the simulation tube needs to be replaced, it can simply be pulled out, greatly improving the replacement efficiency of the simulation tube. Attached Figure Description

[0041] Example 1

[0042] like Figures 2-3 As shown, a connecting component of a fixed anchoring section simulation structure includes a test frame 1, a base 2, a support pipe 3, a support seat 4, and a baffle 8. The base 2 is installed inside the test frame 1. One end of the support pipe 3 is set on the base 2, and the other end of the support pipe 3 is connected to the support seat 4. The support seat 4 is provided with an inner groove 6, which is used to abut against the head end of the simulation pipe 10. The baffle 8 is used to be set at the tail end of the simulation pipe 10, and the baffle 8 abuts against one end of the test frame 1.

[0043] This application discloses a connecting component for a fixed anchorage section simulation structure. A base 2 is installed inside a test frame 1, a support pipe 3 is mounted on the base 2, a support seat 4 is connected to the support pipe 3, and an inner groove 6 is provided on the support seat 4. In actual use, such as... Figure 4As shown, the head end of the simulation tube 10 extends into the test frame 1 until it abuts against the bottom of the inner groove 6, thereby fixing and limiting the simulation tube 10 within the test frame 1, effectively preventing the simulation tube 10 from shaking significantly during the test. Furthermore, as shown... Figure 5 As shown, the baffle 8 is set at the tail end of the simulation tube 10. The baffle 8 abuts against one end of the test frame 1, thereby limiting the tail end of the simulation tube 10. The connecting component of the fixed anchoring section simulation structure of this application can limit both ends of the simulation tube 10, thereby installing the simulation tube 10 on the test frame 1. When the simulation tube 10 needs to be replaced, it can be pulled out, which greatly improves the replacement efficiency of the simulation tube 10.

[0044] In this application, as Figure 5 As shown, outer partitions 101 are provided at both ends of the test frame 1. Holes are provided on the outer partitions 101 for the simulation tube 10 to pass through. In actual operation, the baffle 8 is first fixed to the tail of the simulation tube 10, and then the head of the simulation tube 10 is pushed through the outer partition 101 and extended inward until the head of the simulation tube 10 abuts against the bottom of the inner groove 6. At this time, the baffle 8 also abuts against the outer partition 101 of the test frame 1, thereby limiting the two ends of the simulation tube 10.

[0045] In one or more implementations, such as Figure 6 , Figure 7 As shown, it also includes a sleeve 5 connected to the base 2, and a support pipe 3 threadedly connected to the sleeve 5.

[0046] Since the support tube 3 is threaded onto the sleeve 5, its length on the sleeve 5 can be adjusted by rotating the support tube 3, which makes it easier to control the support seat 4 to move closer to or further away from the simulation tube 10.

[0047] In actual operation, to ensure effective limiting of both ends of the simulation tube 10, the support tube 3 should first be partially retracted into the sleeve 5, and then the simulation tube 10 should be installed. After the baffle 8 abuts against the test frame 1, the support tube 3 should be rotated so that it gradually extends out of the sleeve 5. The support tube 3 drives the support seat 4 to move closer to the simulation tube 10 until the bottom of the inner groove 6 on the support seat 4 abuts against the top of the simulation tube 10. Figure 5 .

[0048] Furthermore, the inner wall of the sleeve 5 is provided with a first internal thread;

[0049] The outer wall of the support tube 3 is provided with a first external thread that matches the first internal thread.

[0050] The sleeve 5 and the support tube 3 are connected by a first internal thread and a first external thread.

[0051] In an optional embodiment, the bottom of the inner groove 6 is provided with a connecting hole 7, which penetrates the support base 4. By providing the connecting hole 7, the inner groove 6 passes through the support base 4, facilitating the anchor 20 inside the simulated tube 10 to pass through the support base 4.

[0052] In an optional embodiment, the inner groove 6 is a cylindrical groove;

[0053] The inner groove 6 is coaxially arranged with the support tube 3.

[0054] In an optional embodiment, the inner diameter of the groove 6 is larger than the outer diameter of the simulated tube 10;

[0055] Furthermore, the inner diameter of the connecting hole 7 is smaller than the outer diameter of the simulated tube 10.

[0056] The inner diameter of the inner groove 6 is larger than the outer diameter of the simulation tube 10 to ensure that the simulation tube 10 can be inserted into the inner groove 6;

[0057] The inner diameter of the connecting hole 7 is smaller than the outer diameter of the simulation tube 10 to prevent the simulation tube 10 from protruding from the connecting hole 7 and to ensure that the simulation tube 10 abuts against the bottom of the inner groove 6.

[0058] In an optional implementation, the sleeve 5 is a steel pipe.

[0059] In an optional embodiment, the support pipe 3 is a steel pipe.

[0060] In an optional embodiment, the base 2 is provided with a first through hole 21, which is coaxially arranged with the support tube 3.

[0061] By setting a first through hole 21, which is coaxially arranged with the support tube 3, it is convenient for the anchors in the simulated tube 10 to pass through the base 2.

[0062] In an optional embodiment, mounting plates 22 are provided on the upper and lower sides of the base 2. The mounting plates 22 are horizontally arranged and are used to connect with the test frame 1, such as... Figure 4 Specifically, the mounting plate 22 is bolted to the test frame 1;

[0063] Furthermore, in this application, such as Figure 4 , Figure 5 As shown, the test frame 1 is composed of an outer partition 101, an inner partition 102, and a crossbar 103. The two outer partitions 101 are connected by multiple crossbars 103, which are parallel to each other. The inner partitions 102 are spaced between the two outer partitions 101 and are connected to the crossbars 103. Both the outer partitions 101 and the inner partitions 102 have holes so that the simulation tube 10 can pass through.

[0064] Mounting plate 22 is bolted to crossbar 103 of test frame 1.

[0065] In optional implementations, such as Figure 8 , Figure 9 As shown, baffle 8 is an annular plate, and baffle 8 is sleeved on the tail end of simulation tube 10.

[0066] Specifically, the simulation tube 10 is generally made of steel pipe, and the baffle 8 is an annular steel plate. The baffle 8 is fitted onto the tail end of the simulation tube 10, and then the two are connected together by welding.

[0067] Specifically, when the simulation tube 10 is installed on the test frame 1, the baffle 8 abuts against the outer partition 101 of the test frame 1, such as... Figure 5 .

[0068] Example 2

[0069] Based on Example 1, such as Figure 4 As shown, this embodiment also discloses a connecting component for a fixed anchoring section simulation structure. The test frame 1 has outer partitions 101 at both ends. The outer partitions 101 have holes for the simulation tube 10 to pass through. Furthermore, it also includes a retaining ring 9 installed on the outer partitions 101. The retaining ring 9 is located on the side of the outer partitions 101 away from the annular plate 8. The retaining ring 9 has a support hole. The support hole is coaxial with the hole on the outer partitions 101. The support hole is used to support the body of the simulation tube 10.

[0070] When the diameter of the simulation tube 10 decreases, a retaining ring 9 is installed on the outer partition 101. The retaining ring 9 has a support hole in the middle. The support hole is coaxial with the hole on the outer partition 101. The simulation tube 10 is supported by the support hole to accommodate the decrease in the diameter of the simulation tube 10. The support hole is matched with the diameter of the simulation tube 10.

[0071] Specifically, when the diameter of the simulation tube 10 decreases, a retaining ring 9 matching the replaced simulation tube 10 is installed on the outer partition 101.

[0072] In optional implementations, such as Figure 5 As shown, multiple inner partitions 102 are spaced apart inside the test frame 1, and retaining rings 9 are also installed on the inner partitions 102.

[0073] Example 3

[0074] Based on Example 1 or Example 2, such as Figure 10 As shown in the figure, the connecting member of a fixed anchorage section simulation structure in this embodiment is actually used as follows:

[0075] First, install the anchor 20 so that one end of the anchor 20 is inside the simulation tube 10 and the other end extends out of the simulation tube 10. Then, grout is injected into the inside of the simulation tube 10. After the grout solidifies, it forms a grout body 30, which encloses the anchor 20 inside the simulation tube 10.

[0076] Then the head end of the simulation tube 10 extends into the test frame 1 until the baffle 8 at the tail end of the simulation tube 10 abuts against one end of the test frame 1. Then the support seat 4 is adjusted so that the bottom of the inner groove 6 on the support seat 4 abuts against the head end of the simulation tube 10. At this time, the anchor 20 passes through the support seat 4, the support tube 3, the base 2 and the inner partition 102 and outer partition 101 of the test frame 1, and extends to the outside of the test frame 1.

[0077] When conducting the tension test of anchor 20, the tensioning can be performed at the end of anchor 20 outside the test frame 1. At this time, the test frame 1 is equivalent to a concrete beam, and the simulated tube 10 is equivalent to an anchor hole.

[0078] In this embodiment, the anchor 20 includes anchor bolts, anchor cables, and rod-cable composite structures.

[0079] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
