According to one aspect of the present embodiment, an anchor for a rock bolt is provided. FIG. 1 is an elevation view of an anchor with 4 barbed members according to one embodiment of the present application. Fig. 2 is a top view of an anchor with 4 barbed members according to one embodiment of the present application. Referring to fig. 1 and 2, an anchor 200 for a rock bolt includes: a connecting member 210 and a barb member 220, wherein the connecting member 210 is used for connecting with the rod body 100 of the anchor rod; and one end of the barb member 220 is connected to the connection member 210, and the other end of the barb member 220 extends toward the rear end of the shaft body 100 in a diverging manner.

As described in the background, the conventional anchor bolt with an anchor requires grouting immediately every time the anchor bolt is installed during construction, so that the installation process is complicated and the installation process takes a long time.

To address this technical problem, the present embodiment provides an anchor 200 for a rock bolt, as shown in fig. 1. Anchor 200 is divided into two portions, connecting member 210 and barbed member 220. Wherein one end of the connecting member 210 is connected with the barb member 220 and the other end of the connecting member 210 is connected with the rod body 100 of the anchor bar. When one end of the connecting member 210 is mounted on the shank 100 of the anchor, the barb member 220 connected to the other end of the connecting member 210 is also mounted on the shank 100 of the anchor. During the construction using the anchor, a construction worker may perform grouting through the hollow sleeve-shaped coupling member 210 and the rod body 100 of the hollow tubular anchor. The other end of the barb member 220 is an umbrella structure that extends in a diverging manner toward the rear end of the shank 100 of the anchor. When the anchor rod is inserted into the opening, the barb parts 220 of the anchor 200 are changed from the constraint state to the divergent state and are popped out all around, forming barbs to be embedded into the surrounding soil body or surrounding rock, and forming strong frictional resistance, thereby realizing temporary anchoring.

Preferably, each anchor 200 can assume a pull force of 50-60 kN. The anchor 200 not only effectively reinforces the anchor function, but also causes the tip of the barbed member 220 to penetrate into the soil or the surrounding rock to generate a strong resistance, so that the anchor does not easily slip out backward and is tightly integrated with the soil or the surrounding rock.

Therefore, the use of the anchor rods with the anchors 200 supports the installation of all the anchor rods of each excavation cycle and then the uniform grouting, and the original complicated flow that the grouting must be performed immediately after each anchor rod is installed is improved. Furthermore, the anchor rod grouting device solves the technical problems that in the prior art, grouting is required to be performed immediately when one anchor rod is installed in the process of building construction of the anchor rod with the anchor rod, the installation process is complex, and the installation process is long in time consumption.

Optionally, the number of barb elements 220 is 3-6, distributed along a circumference about the shaft 100 as an axis.

Specifically, fig. 3 is a front view of an anchor with anchors according to one embodiment of the present application. Referring to fig. 1 and 3, the number of the barb parts 220 may be varied according to the need of building construction, and the number of the barb parts 220 is generally 3 to 6. For example, when the construction environment is severe and the surrounding rock composition is loose, the constructor may select the anchor 200 with the 6 barbed members 220 so that the anchor rod with the anchor 200 has one end fixed in the surrounding rock. The barb elements 220 are circumferentially distributed about the axis of the shaft 100. During the construction, the barb member 220 is transformed from the restrained state to the divergent state and is clamped in the surrounding rock so that one end of the anchor rod is fixed in the surrounding rock. Accordingly, the operation in which the constructor can freely set the number of the barb parts 220 of the anchor 200 according to the engineering requirement achieves the technical effect of enabling the anchor rod with the anchor 200 to be adapted to different building construction environments according to the engineering requirement.

Optionally, the number of barb members 220 is 3.

Specifically, fig. 4 is an elevation view of an anchor with 3 barb members according to one embodiment of the present application. Fig. 5 is a top view of an anchor with 3 barb members according to one embodiment of the present application. Referring to fig. 4 and 5, the number of the barb parts 220 may be freely set according to various construction environments. For example, because the wall rock environment is relatively good in a class IV wall rock environment (representing a large collapse that may occur if the arch is unsupported and the sidewalls are sometimes unstable), in a class IV wall rock environment, the constructor may select an anchor 200 with 3 barbed members 220 so that one end of the bolt with anchor 200 is anchored in the wall rock.

Optionally, the number of barb members 220 is 4.

Specifically, referring to fig. 1 and 2, the number of barb members 220 may be freely set according to various construction environments. For example, when building construction is performed in an earth environment, since a surrounding rock environment in the earth environment is poor, a constructor may select the anchor 200 having the 4 barb members 220 in the earth environment, so that one end of the anchor rod having the anchor 200 is fixed in the surrounding rock.

Optionally, the number of barb members 220 is 5.

Specifically, fig. 6 is an elevation view of an anchor with 5 barbed components according to one embodiment of the present application. FIG. 7 is a top view of an anchor with 5 barb members according to one embodiment of the present application. Referring to fig. 6 and 7, the number of barb members 220 can be freely set according to various construction environments. For example, since the surrounding rock environment is poor in the surrounding rock environment of the V-class, the constructor may select the anchor 200 with the 5 barbed members 220 so that one end of the anchor rod with the anchor 200 is fixed in the surrounding rock environment of the V-class.

Alternatively, the other end of the barb elements 220 form a single sharp raised structure 221.

Specifically, referring to fig. 1, 2, 4, 5 or 6, the other end of the barb member 220 is a single sharp raised structure 221. During the construction process, the single sharp raised structure 221 can be inserted into the gap of the surrounding rock and clamped in the deep position of the gap of the surrounding rock. Thus, the operation of forming the single sharp projection structure 221 at the other end of the barb member 220 can achieve the technical effect of making it easier to insert the anchor with the anchor 200 into the surrounding rock.

Optionally, the other end of barb elements 220 form a plurality of sharp raised structures 222.

Specifically, FIG. 8 is an elevation view of an anchor with multiple pointed raised structures according to one embodiment of the present application. Referring to fig. 8, the other end of barb member 220 is provided with a plurality of pointed raised structures 222. Because the number of the plurality of sharp-pointed protrusion structures 222 is large, the plurality of sharp-pointed protrusion structures 222 are suitable for the building construction process with a complicated surrounding rock environment. The operation of providing the plurality of sharp protrusion structures 222 on the barbed member 220 enables the anchor rod with the anchor 200 to be inserted and fixed into a fine gap of surrounding rock, thereby achieving the technical effect of improving the safety and stability of construction under a severe surrounding rock environment.

The operation of providing the connecting member 210 with a hollow sleeve-like structure and the inner surface of the connecting member 210 with the

threads

211, 212 achieves the technical effects of facilitating grouting at the time of construction work and allowing the anchor 200 to be freely detached.

Optionally, the

211, 212 comprise a first thread 211 and a second thread 212 provided at both ends of the sleeve.

Specifically, referring to FIG. 9, the connecting member 210 of the anchor 200 is provided with first and

second threads

211 and 212. The first and

second threads

211 and 212 may be respectively connected to the rods 100 of the plurality of anchor rods, so that the rods 100 of the plurality of anchor rods can be connected together by the anchor 200 to form a rod splice. And, the operation of the anchors 200 provided for the rod bodies 100 connected to the plurality of anchor rods can reinforce the stability between the anchor rods and the surrounding rock, thereby achieving the technical effect of improving safety and stability in the middle of the construction process.

According to another aspect of the present embodiment, there is also provided an anchor comprising a rod body 100, a fixing mechanism 300, wherein the fixing mechanism 300 is disposed at a rear end of the rod body 100 with respect to an insertion direction for fixing the rod body 100 to an engineering structure after the rod body 100 is inserted into a surrounding rock, and an anchor 200 for an anchor, the anchor 200 being connected to the rod body 100 by a connecting member 210.
