Description

Technical Field

[0001] The utility model relates to the technical field of rock slope support, in particular to a high-strength anchor structure used for rock slopes. Background Art

[0002] For rock slopes, the rock mass strength is high and the anchor cable construction is difficult. The number of anchor cables in the support structure greatly affects the project cost. Commonly used support structures are reinforced concrete frame beams arranged along the slope surface. Within the same support unit length, a prestressed anchor cable is set at the frame beam node position. The frame beam bears concentrated loads at the anchor cable position, and its cross-sectional size and reinforcement are large. Figure 6 This is a physical picture of the existing rock slope being fixed and supported by anchor cables. Utility Model Content

[0003] The technical problem to be solved by the present invention is to provide a high-strength anchor structure for rock slopes, so as to solve the problem of concentrated force on the frame beams corresponding to the anchor cables of the rock slopes in the prior art described in the background art.

[0004] To achieve the above purpose, the present invention provides the following technical solutions: a high-strength anchor structure for rock slopes, comprising

[0005] A base, facing the node of the sash beam, and having a through hole passing through the base;

[0006] A plurality of diagonal braces are arranged in a circular shape around the base, with one end fixedly connected to the base and the other end fixedly connected to the frame beam;

[0007] Anchor cables pass through the steel strand holes and through holes at the nodes of the lattice beams.

[0008] Preferably, the frame beam is made of section steel, the base is a section steel base, the diagonal brace is a section steel diagonal brace, and the diagonal brace is welded to the frame beam and the base.

[0009] Preferably, the frame beam is made of reinforced concrete, the base is a steel base, the diagonal brace is a steel diagonal brace, the diagonal brace is welded to the base, the diagonal brace has an embedded body embedded in the concrete of the frame beam, the embedded body has a positioning hole, and the steel bars in the frame beam pass through the positioning hole.

[0010] The beneficial effects of adopting the above technical solution are:

[0011] By setting up a base and diagonal braces, the present application can evenly disperse the pressure applied to the base by the anchor cable through the four diagonal braces, and disperse the force to the frame beam through the diagonal braces, thereby avoiding excessive force at the nodes of the frame beam, which may cause deformation and damage to the frame beam.

[0019] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0020] like Figure 1-5 In the first embodiment, a high-strength anchor structure used for rock slopes includes:

[0021] The base 20 is opposite to the node of the sash beam 10, and the base 20 has a through hole 21 passing through the base 20;

[0022] A plurality of diagonal braces 30 are arranged in a circular shape around the base 20, with one end fixedly connected to the base 20 and the other end fixedly connected to the lattice beam 10;

[0023] The anchor cable 40 passes through the steel rope holes 11 and the through holes 21 at the nodes of the lattice beam 10 .

[0024] This embodiment is implemented as follows:

[0025] When the present application is in use, the anchor cable 40 passes through the steel rope hole 11 and the through hole 21, so that the anchor cable 40 can apply pressure to the base 20 through the steel pad (a plate used to tighten and fix the end of the anchor cable, which is the existing technology). The pressure of the base 20 will be dispersed to the diagonal brace 30, and the force can be applied to the lattice beam 10 through the diagonal brace 30, so that the lattice beam 10 will not be subjected to the pressure of all the anchor cables 40 at a single position.

[0026] The advantage of the present application over the prior art is that it avoids damage and deformation of the lattice beam.

[0027] See also Figure 1 、 2 , 3, 5, the frame beam 10 is a steel section, the base 20 is a steel section base, the diagonal brace 30 is a steel section diagonal brace, and the diagonal brace 30 is welded to the frame beam 10 and the base 20.

[0028] The diagonal brace 30 , the lattice beam 10 and the base 20 are made of steel, and the connections between them can be fixed by welding, so the installation is simple.

[0029] See also Figure 4 The frame beam 10 is made of reinforced concrete, the base 20 is a steel base, the diagonal brace 30 is a steel diagonal brace, the diagonal brace 30 is welded to the base 20, and the diagonal brace 30 has an embedded body 31 embedded in the concrete of the frame beam 10. The embedded body 31 has a positioning hole 32, and the steel bar in the frame beam 10 passes through the positioning hole 32.

[0030] When the lattice beam 10 is made of reinforced concrete, the diagonal brace 30 can be fixed to the lattice beam 10 by passing the steel bar through the positioning hole 32 of the embedded body 31 .

[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all fall within the scope of protection of the present invention.
