Description

Technical Field

[0001] The utility model relates to the technical field of anchoring, in particular to a sleeve for an anchor bolt. Background Art

[0002] The anchor bolts currently used in masonry with holes achieve the anchoring effect by expanding the sleeve, generating expansion and extrusion force with the masonry, and generating pull-out force through shear friction. During on-site construction, the expansion of the sleeve is often uneven, and the sleeve may cause stress concentration, which will have an adverse effect on the performance of the structure. Utility Model Content

[0003] The technical problem to be solved by the utility model is: to provide a sleeve for an anchor bolt in order to overcome the deficiencies in the prior art.

[0004] The utility model solves the technical problem by adopting a technical solution: an anchor sleeve, comprising a sleeve body, wherein the outer side wall of the sleeve body is provided with a plurality of long straight ribs extending from top to bottom and connecting ribs and connecting rings connecting adjacent long straight ribs.

[0005] The connecting ribs are evenly distributed on the outer wall of the sleeve body from top to bottom, and the connecting ribs and the connecting rings between adjacent long straight ribs are connected as one piece.

[0006] A groove with openings is formed between adjacent connecting ribs, and the openings are evenly distributed around the circumference of the sleeve body.

[0007] During assembly, the connecting ring is fitted to the masonry part of the masonry with holes.

[0008] When in use, the anchoring glue flows out of the opening to the opening of the masonry with holes. The openings are evenly distributed to ensure that the anchoring glue overflows from the openings evenly, without causing stress concentration; the overflowing anchoring glue fills the opening and presses against the masonry, and after the anchoring glue is cured, it is directly consolidated with the masonry with holes, so that the sleeve, the anchoring glue and the masonry with holes are consolidated, generating pull-out resistance and achieving an anchoring effect.

[0009] Furthermore, a convex ring is provided at one end of the opening of the sleeve body to limit the sleeve body inserted into the mounting hole, ensuring that the opening portion of the perforated masonry corresponds to the opening on the sleeve body, and the connecting ring fits the masonry portion of the perforated masonry, so that the anchoring glue overflows to the opening portion of the perforated masonry.

[0010] Furthermore, on the outer side wall of the sleeve body, long straight ribs protrude from the connecting ribs and the connecting ring. The long straight ribs form a protrusion, which increases the strength of the sleeve on the one hand and the integrity of the sleeve on the other hand.

[0011] Specifically, the protruding height of the long straight rib is 2-8 mm, and the width of the long straight rib is 2-8 mm.

[0012] The beneficial effects of the utility model are as follows: the openings evenly distributed on the circumference of the sleeve body ensure that the anchoring glue overflows from the openings evenly, and stress concentration will not be caused; the overflowing anchoring glue is filled in the opening part and presses against the masonry part, and after the anchoring glue is solidified, it is directly consolidated with the masonry with holes, so that the sleeve, the anchoring glue and the masonry with holes are consolidated, generating pull-out resistance and achieving an anchoring effect.

[0017] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Figure 1 and Figure 2 The anchor sleeve shown in the figure comprises a sleeve body 1, on the outer side wall of the sleeve body 1 are provided four long straight ribs 14 extending from top to bottom and connecting ribs 11 and connecting rings 13 connecting adjacent long straight ribs 14.

[0019] The connecting ribs 11 are evenly distributed on the outer wall of the sleeve body 1 from top to bottom, and the connecting ribs 11 and the connecting rings 13 between adjacent long straight ribs 14 are connected as one piece.

[0020] A groove with openings 12 is formed between adjacent connecting ribs 11, and the openings 12 are evenly distributed around the circumference of the sleeve body 1.

[0021] During assembly, the connecting ring 13 is attached to the masonry portion 41 of the masonry 4 with holes.

[0022] When in use, the anchoring glue 3 flows out of the opening 12 to the opening portion 42 of the perforated masonry 4. The openings 12 are evenly distributed to ensure that the anchoring glue 3 evenly overflows from the opening 12, and does not cause stress concentration; the overflowing anchoring glue 3 fills the opening portion 42 and abuts against the masonry portion 41, and the anchoring glue 3 is directly consolidated with the perforated masonry 4 after solidification, so that the sleeve, the anchoring glue 3 and the perforated masonry 4 are consolidated, generating a pull-out resistance, and achieving an anchoring effect.

[0023] A convex ring 15 is provided at one end of the opening of the sleeve body 1 to limit the sleeve body 1 inserted into the hole, ensuring that the opening portion 42 of the perforated masonry 4 corresponds to the opening 12 on the sleeve body 1, and the connecting ring 13 is fitted to the masonry portion 41 of the perforated masonry 4, so that the anchoring glue 3 overflows to the opening portion 42 of the perforated masonry 4.

[0024] On the outer side wall of the sleeve body 1, long straight ribs 14 protrude from the connecting ribs 11 and the connecting ring 13. The protrusions formed by the long straight ribs 14 increase the strength of the sleeve on the one hand, and increase the integrity of the sleeve on the other hand.

[0025] Specifically, the protruding height of the long straight rib 14 is 2-8 mm, and the width of the long straight rib 14 is 2-8 mm.

[0026] During assembly, first use a hollow dust-free drill to drill a hole in the perforated masonry 4. After completion, insert the sleeve body 1 into the drilled installation hole, then inject a proper amount of anchoring glue 3 into the sleeve body 1, and then rotate and insert the screw 2. At this time, the anchoring glue 3 evenly overflows from the opening 12 on the sleeve body 1 to the opening part 42 of the perforated masonry 4 and presses against the masonry part 41. After the anchoring glue 3 is cured, that is, when the sleeve, the anchoring glue 3 and the perforated masonry 4 are consolidated, tighten the nut after fixing the load at the end of the screw 2.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
