[0021] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0022] like Figures 1-5 As shown, a device for testing the pull-out bearing capacity of dense anchors includes a base plate 3 and a clamping ring. A first lifting mechanism 5 is installed on the upper side of the base plate 3. A connecting plate 10 is installed at the upper end of the first lifting mechanism 5. A first gap groove 8 is opened on the base plate 3, and a second gap groove 11 is opened on the connecting plate 10. A second lifting mechanism 7 is detachably installed between the base plate 3 and the connecting plate 10.
[0023] Two side support plates 13 are also installed on the connecting plate 10. The two side support plates 13 are located on both sides of the second gap groove 11. A top plate 16 that can be vertically slidably connected is installed on each of the two side support plates 13 through a telescopic rod 14. A pressure sensor 15 is fixedly connected between the side support plate 13 and the top plate 16. The clamping ring is located on the upper side of the top plate 16.
[0024] In use, the clamping ring is fixedly connected to the outside of the rear anchor 2. The base plate 3 is placed on the upper side of the planar structure 1. The base plate 3 is moved so that the rear anchor 2 is located inside the first gap groove 8 and the second gap groove 11, and the two top plates 16 are positioned below the clamping ring. Then, the second lifting mechanism 7 is installed so that the clamping ring is located between the first lifting mechanism 5 and the second lifting mechanism 7. The first lifting mechanism 5 and the second lifting mechanism 7 can then be activated to apply an upward thrust to the clamping ring, thereby applying an upward pull force to the rear anchor 2. The anchor 2 is subjected to pull-out bearing capacity testing. During the testing process, the pull-out force on the rear anchor 2 can be detected by the pressure sensor 15. During the testing process, by setting the connecting plate 10 between the tied transverse steel bars on the outside of the rear anchor 2, the pressure sensor 15 and the clamping ring can be horizontally offset. Thus, when the first lifting mechanism 5 and the second lifting mechanism 7 are placed on both sides of the rear anchor 2, the pull-out bearing capacity of the rear anchor 2 with the transverse steel bars tied on the outside can be tested relatively simply, and the stability during the testing process is high.
[0025] The second jacking mechanism 7 can be a jack, an electric push rod or other mechanism capable of applying upward thrust.
[0026] The planar structure 1 can be ground or concrete roof or the like structure.
[0027] As shown in the drawings, the bottom plate 3 is provided with a first gap groove 8, and the first jacking mechanism 5 is arranged in the first gap groove 8. Figures 2-3 The lower end of the second jacking mechanism 7 is clamped in the lower sliding seat 6, thereby fixing the lower end of the second jacking mechanism 7.
[0028] Meanwhile, the first sliding seat 4 is slidably connected to the upper side of the bottom plate 3, the lower sliding seat 6 is slidably connected to the bottom plate 3, the connecting plate 10 is slidably connected to the inside of the guide frame 9, and the upper sliding seat 12 is slidably connected to the outside of the connecting plate 10.
[0029] As shown in the drawings, the first sliding seat 4, the lower sliding seat 6, the guide frame 9 and the upper sliding seat 12 can be fixedly connected with a magnet 22. Figures 2-3 The bottom plate 3 and the connecting plate 10 are made of metal material with magnetism, such as iron.
[0030] As shown in the drawings, the clamping ring includes two outer arc-shaped clamps 17, and the two outer arc-shaped clamps 17 are fixedly connected with side plates 19 on both sides. Figures 4-5 The side plate 19 on the outer side of one of the outer arc-shaped clamps 17 is fixedly connected with a threaded sleeve 21, and the side plate 19 on the outer side of the other outer arc-shaped clamp 17 is inserted with a locking screw 20. The locking screw 20 and the threaded sleeve 21 are threadedly connected, and the inner side of each of the two outer arc-shaped clamps 17 is provided with an inner gasket 18.
[0031] The inner gasket 18 can be fixedly connected to the inside of the outer arc-shaped clamp 17 or independently arranged with the outer arc-shaped clamp 17.
[0032] And, the outer diameter of the two inner gaskets 18 gradually decreases in order from top to bottom, and the inner diameter of the two outer arc-shaped clamps 17 gradually decreases in order from top to bottom, so that when the connecting plate 10 exerts a pushing force on the outer arc-shaped clamps 17 upwards, the outer arc-shaped clamps 17 exert a pushing force on the inner gaskets 18 to approach the rear anchor 2, increase the friction between the inner gaskets 18 and the rear anchor 2, thereby improving stability and reducing the vertical movement of the clamping ring outside the rear anchor 2.
[0033] The above description is only preferred embodiments of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the principles of the present application, can make a number of improvements and refinements, these improvements and refinements should also be considered within the scope of the present application. The structure, device and operation method not specifically described and explained in the present application, if not specifically described and limited, are implemented according to conventional means in the art.
