At least two second screw holes 12 are opened on opposite sides of the barrel 10 with respect to the first screw holes 11;
the second threaded hole 12 is arranged opposite to the first threaded hole 11;
The end part of the reinforcing steel bar 20 extending into the cylinder body is provided with a pipe perforation;
The bolt 30 passes through the barrel body through the first screw hole 11 and/or the second screw hole 12 and is in contact with the reinforcing steel bar 20 positioned in the barrel body 10, or passes through the first screw hole 11, the through hole 21 and the second screw hole 12 in sequence;
The side wall of the barrel 10 further comprises a plurality of pouring holes 13, and cement mortar poured through the pouring holes 13 is filled in the cavity of the barrel 10.
It will be appreciated that the body 10 is a hollow cylinder with one end of the rebar 20 extending into the body 10. The barrel 10 is provided with a plurality of first threaded holes 11 penetrating through the side wall of the barrel 10, and bolts 30 penetrate through the first threaded holes 11 and are connected through threads. Since the first screw hole 11 penetrates the sidewall of the body 10, the end of the bolt 30 is screwed into the first screw hole 11, and then abuts against the reinforcing bar 20, thereby fixing the reinforcing bar 20 in the body 10.
Further, the body 10 further includes a second screw hole 12 disposed opposite to the first screw hole 11, and the end of the reinforcing bar 20 is provided with a pipe penetration hole, so that when the reinforcing bar 20 is inserted into the pipe penetration hole to be opposite to the first screw hole 11 and the second screw hole 12, the bolt 30 can sequentially pass through the first screw hole 11, the through hole and the second screw hole 12 and be connected by screw.
Further, the bolts 30 may pass through the body 10 from the first bolt holes 11 and the second bolt holes 12, respectively, to abut against the reinforcing bars. Since the first bolt hole 11 and the second bolt hole 12 are disposed opposite to each other, the reinforcing bar 20 is fixed by an inward force applied by the oppositely disposed bolts 30, and has stability.
Further, the barrel 10 further comprises a plurality of pouring holes 13, and cement mortar is poured into the cavity of the barrel 10 through the pouring holes 13 after the bolts 30 fix the reinforcing steel bars 20 in the barrel 10, so that the strength of the reinforcing steel bar anchoring sleeve is increased.
Further, referring to fig. 3 to 4, a reinforcing bar 20 is now inserted from one end of the body 10 to the middle position of the body 10, and bolts 30 are sequentially screwed from the edge of the body 10 near the insertion direction of the reinforcing bar 20 to the middle to fix the reinforcing bar 20. Then, the other reinforcing bar 20 is inserted into the body 10 from the other end of the body 10 to the end of the two reinforcing bars 20, and the bolts 30 are sequentially screwed from the edge of the body 10 near the direction in which the reinforcing bars 20 are inserted toward the middle. At this time, both reinforcing bars 20 are fixed in the barrel 10, and optionally, the heads of the bolts 30 may be twisted off to make the outer surface of the barrel 10 flat.
In the embodiment provided by the utility model, the two steel bars 20 are stretched into the same cylinder body 10, and the steel bars 20 are fixed with the cylinder body 10 through the bolts 30 penetrating through the threaded holes 11, so that the connection of the two steel bars 30 is realized, and the utility model has the advantages of simple structure, convenience in installation and rich application scenes.
In an alternative embodiment, referring to fig. 5, the rebar anchor sleeve further includes a seal (not shown) and a plug (not shown);
The sealing parts are arranged at two opposite ends of the cylinder body 10 and fill the gap between the inner wall of the cylinder body 10 and the steel bars 20;
The blocking member is disposed in the pouring hole 13.
It will be appreciated that since the reinforcing bars 20 extend into the barrel 10, there is a gap between the reinforcing bars 20 and the barrel 10. Therefore, a seal is provided at the end of the barrel 10 to seal the gap and prevent the cement mortar from flowing out during pouring. The sealing member may be made of rubber, metal or the like.
Further, the sealing device also comprises a sealing piece, wherein the sealing piece is used for sealing the pouring hole 13 so as to seal the cylinder body 10.
In an alternative embodiment, the length of the bolt 30 sequentially passing through the first screw hole 11, the through hole 21, and the second screw hole 12 is not smaller than the outer diameter of the barrel 10.
It will be appreciated that the bolts 30 include long bolts and short bolts. Wherein, the short bolt is used for supporting the end against the reinforcing steel bar 20 after passing through the first threaded hole 11. The long bolt is used to fix the reinforcing bar 20 and the body 10 together by passing through the first screw hole 11, the through hole 21 and the second screw hole 12 in this order. The two fixing modes can enhance the stability of the steel bar anchoring sleeve.
Further, the length of the long bolt, that is, the bolt 30 passing through the first screw hole 11, the through hole 21 and the second screw hole 12 is at least not small in the outer diameter of the barrel 10 to ensure sufficient bolting with the first screw hole 11 and the second screw hole 12.
In an alternative embodiment, the portion of the bolt 30 extending out of the barrel 10 passing through the first threaded hole 11, the through hole 21 and the second threaded hole 12 in sequence is bolted with a nut 31.
It will be appreciated that since the length of the bolt 30 passing through the first screw hole 11, the through hole 21 and the second screw hole 12 in this order is not smaller than the outer diameter of the barrel 10, and generally longer than the outer diameter of the barrel 10, the nut 31 is bolted to the portion of the bolt 30 extending out of the barrel 10, and the barrel 10 and the reinforcing bars can be further fixed.
In an alternative embodiment, the extensions of the first bolt hole 11 and the casting hole 13 are parallel to each other.
It is understood that the plurality of first bolt holes 11 are arranged along the same straight line, and the arrangement direction of the plurality of first bolt holes 11 is parallel to the rotation center line of the cylinder body 10. When fixing the reinforcing bars 20, the bolts 30 may be sequentially tightened from one end near the edge of the body 30 toward the center. The plurality of first bolt holes 11 are arranged in parallel with the rotation center of the cylinder body 10 along the same straight line. That is, the direction of the force applied when the plurality of bolts 11 are fixed to the reinforcing bar 20 is the same, and the stability of fixing the bolts 30 to the reinforcing bar 20 can be improved, and displacement of the reinforcing bar 20 can be prevented.
Further, the pouring holes 13 are also arranged along the same straight line, and the arrangement direction of the first bolt holes 11 is parallel to the rotation center line of the barrel 10, that is to say, the extension lines of the first bolt holes 11 and the pouring holes 13 are parallel to each other, so that the barrel 10 can be prevented from being excessively perforated on a certain straight line, and the strength is reduced.
In an alternative embodiment, the inner diameter of the barrel 10 is greater than the outer diameter of the rebar 20.
It will be appreciated that the inner diameter of the body 10 is greater than the outer diameter of the reinforcing bars 20 in order to ensure that the reinforcing bars 20 can extend into the body 10. The dimensions of the body 10 and the reinforcing bars 20 are not particularly limited in the present utility model. In practical application, the inner diameter 10 of the cylinder body 10 can be larger than the outer diameter of the steel bar 20, and the steel bar 20 can be ensured to stretch into smoothly. At the same time, a certain thickness of the barrel 10 is also required to be secured to secure the strength of the barrel 10.
In an alternative embodiment, with continued reference to fig. 1, the inner wall of the barrel 10 is provided with a relief pattern 14.
It will be appreciated that the inner wall of the barrel 10, and in particular the side wall of the barrel 10 opposite the first bolt hole 11, is provided with a relief 14. Since the bolts 30 are screwed into the first bolt holes 11, the reinforcing bars 20 are fixed to the cylinder 10, and the side of the reinforcing bars 20 opposite to the first bolt holes 11 is in contact with the cylinder 10. The concave-convex lines 14 are arranged on the inner wall of the barrel body 10, so that the friction force between the steel bars 20 and the barrel body 10 can be increased, and the connection is firmer.
In an alternative embodiment, two reinforcing bars 20 extend into the barrel 10 from each end of the barrel 10;
The end portion of the reinforcing steel bar 20 extending into the barrel 10 is located in the middle of the barrel 10, and the end portions of the two reinforcing steel bars 20 are mutually abutted.
It will be appreciated that the two reinforcing bars 20 extend into the respective ends of the barrel 10 and extend to the middle of the barrel 10. Since the plurality of first bolt holes 11 are uniformly distributed in the extending direction of the barrel 10. Two reinforcing bars 20 extend into the middle of the barrel 10, and then any one reinforcing bar 20 is fixed by half of bolts 30. Illustratively, referring to fig. 2 or 3, the body 10 includes 8 first bolt holes, and one reinforcing bar 20 is fixed by 4 bolts 30. The length of the barrel 10 and the number of the first bolt holes 11 may be determined according to the reinforcing bars 20 to be connected. When the length of the reinforcing steel bar 20 is longer, the diameter is larger, the length of the cylinder body 10 can be larger, and the number of the first bolt holes 11 can be more, so that stable connection of the reinforcing steel bar 20 is realized.
Further, the ends of the two reinforcing bars 20 need to abut against each other, avoiding the hollow of the barrel 10, resulting in a decrease in the connection strength.
In summary, the steel bar anchoring sleeve provided by the utility model at least has the following beneficial effects:
In the embodiment provided by the utility model, the two steel bars extend into the same cylinder body, and the steel bars are fixed with the cylinder body through the bolts penetrating through the threaded holes, so that the connection of the two steel bars is realized, and the device has the advantages of simple structure, convenience in installation and rich application scenes.
