This method ensures easy opening of the hollow interior and grouting groove of the grouting anchor, improving upon the shortcomings of traditional grouting anchors that lack sealing protection at the interior and grouting groove.

Description

Technical Field

[0001] This utility model relates to the field of fixed building technology, and in particular to a detachable hollow grouting anchor sealing assembly. Background Technology

[0002] Hollow grouting anchors are hollow in the middle. Before grouting, the anchor is placed into the anchor hole, and then grout is injected from the tail of the anchor. The grout passes through the center of the anchor and comes out from the anchor head, filling the perimeter of the anchor, filling all the gaps in the anchor hole and seeping into the fissures of the surrounding rock. This strengthens the bond between the anchor and the surrounding rock and reinforces the surrounding rock.

[0003] For most anchor bolts, the full-length standard large-pitch thread structure on the outer surface of the bolt body facilitates the cutting and extension of the anchor bolt. Compared with a smooth bolt body, it increases the bonding area between the anchor bolt body and the grouting material, thereby improving the anchoring force. However, for some hollow grouting anchor bolts, when not in use, they cannot form a good sealing effect on their slots, resulting in easy blockage of the slots. This leads to poor flow of grouting sand during subsequent use. Therefore, there is an urgent need for a detachable hollow grouting anchor bolt sealing component to improve its sealing effect. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to solve the problems raised in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a detachable hollow grouting anchor sealing assembly, including a grouting anchor, wherein a grouting groove is provided on the surface of the grouting anchor, a sealing gasket is bonded to the inner wall of the grouting groove on the grouting anchor, a power guide rod is slidably installed on the inner side of the grouting anchor, a power support block is welded to the surface of the power guide rod, and an auxiliary pad is welded to the end of the power guide rod away from the power support block.

[0006] Preferably, an extension support plate is welded to the surface of the sealing gasket, and both the power support block and the surface of the extension support plate are inclined surfaces.

[0007] Preferably, an inner retaining ring is bonded and installed on the inner side of the grouting anchor bolt, and the inner side of the inner retaining ring is in a funnel shape.

[0008] Preferably, an elastic washer is bonded to the surface of the power guide rod, and the surface of the elastic washer is abutted against the inner side of the grouting anchor rod.

[0009] Preferably, the elastic washer is made of deformable elastic rubber material.

[0010] Preferably, the surface of the grouting anchor is provided with a support plate and a sealing plug, and an auxiliary support block is bonded to the surface of the grouting anchor.

[0011] Preferably, the inner sides of the support plate and the sealing plug are slidably mounted on the surface of the grouting anchor rod, and the upper side of the sealing plug is abutted against the lower side of the support plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) The detachable hollow grouting anchor sealing assembly has an extended support plate that pushes the sealing gasket to slide out of the inner wall of the grouting groove on the grouting anchor, thereby allowing the sealing gasket to detach from the grouting anchor and form a flow between its interior and the grouting groove. At this time, the sealing gasket at the hollow grouting anchor can be opened, and the power guide rod can be taken out in reverse inside the grouting anchor to open its interior. This method ensures that the hollow interior and grouting groove of the grouting anchor have easy opening operations. On the one hand, it improves the disadvantage of the traditional grouting anchor not having sealing protection inside and at the grouting groove. On the other hand, it also ensures that the power guide rod and sealing gasket at the grouting anchor have easy removal effects, thereby improving the convenience of adjusting and using the grouting anchor as a whole.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0023] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a detachable hollow grouting anchor sealing assembly, including a grouting anchor 1, a support plate 2 and a sealing plug 3 provided on the surface of the grouting anchor 1, the inner sides of the support plate 2 and the sealing plug 3 are slidably installed on the surface of the grouting anchor 1, the upper side of the sealing plug 3 is abutted against the lower side of the support plate 2, and the support plate 2 and the sealing plug 3 are used to install and position the grouting anchor 1.

[0025] Furthermore, an auxiliary support block 6 is bonded to the surface of the grouting anchor rod 1. The function of the auxiliary support block 6 is to assist the operator in controlling and using the grouting anchor rod 1.

[0026] Furthermore, the surface of the grouting anchor 1 is provided with a grouting groove 4, and a sealing gasket 5 is bonded to the inner wall of the grouting groove 4 on the grouting anchor 1. The grouting groove 4 on the grouting anchor 1 is used for grouting and discharging mortar, while the sealing gasket 5 is used to seal the grouting groove 4 on the grouting anchor 1 when it is not in use, so as to reduce the clogging effect when the grouting anchor 1 is not in use.

[0027] Furthermore, a power guide rod 7 is slidably installed on the inner side of the grouting anchor rod 1, a power support block 8 is welded to the surface of the power guide rod 7, an auxiliary pad 9 is welded to the end of the power guide rod 7 away from the power support block 8, an extended support plate 10 is welded to the surface of the sealing gasket 5, the surfaces of the power support block 8 and the extended support plate 10 are both inclined surfaces, an inner retaining ring 11 is bonded to the inner side of the grouting anchor rod 1, an elastic washer 12 is bonded to the surface of the power guide rod 7, and the surface of the elastic washer 12 is abutted against the inner side of the grouting anchor rod 1. The funnel state of the inner retaining ring 11 can assist the smooth sliding adjustment of the elastic washer 12 inside.

[0028] Furthermore, when grouting is required on the grouting anchor 1, the operator only needs to control the auxiliary pad 9 to push the power guide rod 7 down inside the grouting anchor 1. The elastic washer 12 on the power guide rod 7 can be stably placed inside the grouting anchor 1 when not in use due to its own expansion friction. The inner retaining ring 11 limits the elastic washer 12, thus ensuring that the power guide rod 7 has a limiting support effect when not in use inside the grouting anchor 1. When the power guide rod 7 is pushed, the power guide rod 7 drives the elastic washer 12 to adjust through the inner retaining ring 11 by its own deformation. In turn, the power guide rod 7 drives the power support block 8 to push the inclined surface of the outer extension support plate 10 through its own inclined surface, thus making the outer extension support plate 10 lower. The extension plate 10 pushes the sealing gasket 5 to slide out of the inner wall of the grouting groove 4 on the grouting anchor rod 1, thereby causing the sealing gasket 5 to detach from the grouting anchor rod 1 and form a flow between its interior and the grouting groove 4. At this time, the sealing gasket 5 at the hollow grouting anchor rod 1 can be opened, and the power guide rod 7 can be opened inside the grouting anchor rod 1 after being taken out in the reverse direction. This method ensures that the hollow interior of the grouting anchor rod 1 and the grouting groove 4 have simple opening operations. On the one hand, it improves the shortcomings of the traditional grouting anchor rod 1 and the grouting groove 4 not having sealing protection. On the other hand, it also ensures that the power guide rod 7 and the sealing gasket 5 at the grouting anchor rod 1 have the effect of easy removal, thereby improving the convenience of adjusting and using the grouting anchor rod 1 as a whole.

[0029] Working Principle: A detachable hollow grouting anchor sealing assembly. When grouting is required on the grouting anchor 1, the operator simply controls the auxiliary pad 9 to push the power guide rod 7 down inside the grouting anchor 1. The elastic washer 12 on the power guide rod 7 can be stably placed inside the grouting anchor 1 when not in use due to its own expansion friction. The inner retaining ring 11 limits the elastic washer 12, ensuring that the power guide rod 7 has a limiting support effect when not in use inside the grouting anchor 1. When the power guide rod 7 is pushed... Therefore, the power guide rod 7 drives the elastic washer 12 to adjust through the inner retaining ring 11 by its own deformation. Then, the power guide rod 7 drives the power support block 8 to push the inclined surface of the extended support plate 10 through its own inclined surface. Thus, the extended support plate 10 pushes the sealing gasket 5 to slide out of the inner wall of the grouting groove 4 on the grouting anchor rod 1. Then, the sealing gasket 5 is separated from the grouting anchor rod 1, and its interior is connected to the grouting groove 4. At this time, the sealing gasket 5 at the hollow grouting anchor rod 1 can be opened, and the power guide rod 7 can be opened inside the grouting anchor rod 1 after being taken out in the opposite direction.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
