Description

Technical Field

[0001] The present application relates to the technical field of soil nails, and in particular to a bracket for soil nails. Background Art

[0002] A soil nail, in short, is a reinforcement material widely used in the field of civil engineering. It is usually made of steel bars or other metal materials, and its shape and length vary to adapt to different engineering requirements. The soil nail is usually inserted into the pre-opened installation hole in the soil wall. By pouring concrete into the installation hole, the soil nail and the surrounding soil form a tight whole to jointly resist external loads and deformations. However, when the existing soil nail is placed inside the installation hole, the soil nail is at the bottom of the installation hole rather than at the center, and the concrete content at the fitting part between the soil nail and the installation hole is small, which results in the instability of the soil nail. Therefore, a bracket for soil nails is proposed. Summary of the Utility Model

[0003] In order to solve the problem that when the existing soil nail is placed inside the installation hole, the soil nail is at the bottom of the installation hole rather than at the center, and the concrete content at the fitting part between the soil nail and the installation hole is small, which results in the instability of the soil nail, the present application provides a bracket for soil nails.

[0004] The bracket for soil nails provided by the present application adopts the following technical solutions:

[0005] A bracket for soil nails includes a soil nail body. The rod part of the soil nail body is set as a hollow round rod. Both ends of the rod part of the soil nail body are provided with foldable bracket components. The bracket components each include a movable sleeve plate and a fixed sleeve plate. The fixed sleeve plates are fixedly sleeved on the outer surface of the soil nail body, and the movable sleeve plates are movably sleeved on the outer surface of the soil nail body. A moving mechanism is arranged on the soil nail body. The moving mechanism can make the movable sleeve plate move inside the soil nail body, and a plurality of folding frames are arranged between the movable sleeve plate and the fixed sleeve plate. When the movable sleeve plate moves relative to the fixed sleeve plate, the folding frames are bent or unfolded.

[0006] Preferably, at least three folding frames are provided, and the three folding frames are annularly arranged around the soil nail body as the axis.

[0007] Preferably, each folding frame includes two folding plates. One side of the two folding plates facing away from each other is respectively rotatably connected to the movable sleeve plate and the fixed sleeve plate through a first rotating shaft, and the side of the two folding plates facing each other is rotatably connected through a second rotating shaft.

[0008] Preferably, a slider is fixedly connected to the inner surface of the movable sleeve plate, and a chute adapted to the slider is opened on the surface of the soil nail body.

[0009] Preferably, the moving mechanism includes a connecting rod disposed inside the soil nail body. Both ends of the connecting rod are fixedly connected to two groups of sliders respectively. One end of the soil nail body is inserted with a bolt, and one end of the bolt is located inside the soil nail body and is rotatably connected to one of the sliders through a rotating joint.

[0010] In summary, the present application includes the following beneficial technical effects:

[0011] In the utility model, the slider, the connecting rod and the movable sleeve plate are moved by rotating the bolt, so as to adjust the relative position between the movable sleeve plate and the fixed sleeve plate, and the folding frame between the movable sleeve plate and the fixed sleeve plate is bent or unfolded; when the folding frame is unfolded, it is convenient for the soil nail body to be inserted into a preset installation hole on the wall; when the folding frame is bent, the soil nail body can be located at the center of the installation hole, ensuring that the poured concrete is evenly distributed between the outer surface of the soil nail body and the inner surface of the installation hole, and improving the stability of the soil nail body.

[0017] The following further describes the present application in detail with reference to the Figures 1-4 accompanying drawings.

[0018] An embodiment of the present application discloses a bracket for a soil nail, which includes a soil nail body 1. The rod part of the soil nail body 1 is a hollow round rod. Both ends of the rod part of the soil nail body 1 are provided with foldable bracket components. The bracket components each include a movable sleeve plate 2 and a fixed sleeve plate 3. The fixed sleeve plates 3 are all fixedly sleeved on the outer surface of the soil nail body 1, the movable sleeve plates 2 are movably sleeved on the outer surface of the soil nail body 1, a moving mechanism is provided on the soil nail body 1, the moving mechanism can move the movable sleeve plate 2 inside the soil nail body 1, and a plurality of folding frames are provided between the movable sleeve plate 2 and the fixed sleeve plate 3. When the movable sleeve plate 2 moves relative to the fixed sleeve plate 3, the folding frames are bent or unfolded.

[0019] Further, there are at least three sets of folding frames, and the three sets of folding frames are distributed in an annular array with the soil nail body 1 as the axis.

[0020] Further, each folding frame includes two folding plates 5. The opposite sides of the two folding plates 5 are respectively rotatably connected to the movable sleeve plate 2 and the fixed sleeve plate 3 through the first rotating shafts 10, and the opposite sides of the two folding plates 5 are rotatably connected through the second rotating shafts 11.

[0021] Further, a slider 9 is fixedly connected to the inner surface of the movable sleeve plate 2, and a chute 6 adapted to the slider 9 is provided on the surface of the soil nail body 1.

[0022] Further, the moving mechanism includes a connecting rod 7 arranged inside the soil nail body 1. The two ends of the connecting rod 7 are respectively fixedly connected to the two sliders 9. One end of the soil nail body 1 is inserted with a bolt 4, and one end of the bolt 4 is located inside the soil nail body 1 and is rotatably connected to one of the sliders 9 through a rotating joint 8.

[0023] In this embodiment, by rotating the bolt 4, the slider 9, the connecting rod 7 and the movable sleeve plate 2 are moved, so as to adjust the relative positions of the movable sleeve plate 2 and the fixed sleeve plate 3. Before inserting the soil nail body 1 into the preset installation hole on the wall surface, a part of the bolt 4 is screwed out of the soil nail body 1, thereby driving the slider 9, the connecting rod 7 and the movable sleeve plate 2 to move, so that the movable sleeve plate 2 moves away from the fixed sleeve plate 3, and the folding plate 5 is pulled by the movable sleeve plate 2 and the fixed sleeve plate 3 to be in a horizontal state, so that the soil nail body 1 can be smoothly inserted into the installation hole; after the soil nail body 1 is inserted into the installation hole, a part of the bolt 4 is screwed into the soil nail body 1, thereby driving the slider 9, the connecting rod 7 and the movable sleeve plate 2 to move, so that the movable sleeve plate 2 moves close to the fixed sleeve plate 3, and the folding plate 5 is pushed by the movable sleeve plate 2 to be in a bent state. The bent folding plate 5 thus forms a bracket, so that the soil nail body 1 is located at the center of the installation hole, so that the poured concrete is evenly distributed between the outer surface of the soil nail body 1 and the inner surface of the installation hole, and the stability of the soil nail body 1 is improved.
