Abstract
The utility model belongs to the technical field of the steel bar connection sleeve, steel bar connection slot sleeve is disclosed. Its main technical characteristics does: include to have the cylindric sleeve body of internal screw thread sleeve body lateral surface has the edge the axial strip slot of sleeve body is the strip lug between adjacent strip slot. When the operation, the spanner card is on strip slot and strip lug, and the spanner is difficult to skid, has avoided that cause the spanner to drop or personnel drop because of the spanner skids, and the strip slot is easy of the concrete is fixed firm on every side moreover, has avoided droing because of the vibration causes the concrete. But wide application in the connection of the reinforcing bar in places such as building, bridge.
Description
Technical field
The utility model belongs to sleeve technology field, particularly relates to bar connecting grooved sleeve.
Background technology
Due to the needs transported and store, reinforcing bar length has a definite limitation, at bridge or building field, connects between reinforcing bar and is connected by branch sleeve.The branch sleeve of current connecting reinforcement is pipe, pipe inner with the end reinforced internal thread mated, there is following defect in this reinforcing steel bar connecting sleeve tube: one, lateral surface is smooth, when fastening sleeve, spanner easily skids, generally operation aloft, spanner easily comes off, and operating personnel also easily fall down; Its two, sleeve is bonding with surrounding concrete insecure, vibrate time sleeve outside concrete easily separate with sleeve, intensity reduces greatly.
Utility model content
Problem to be solved in the utility model be just to provide a kind ofly be convenient to fix with spanner, use safety, bar connecting grooved sleeve with the fixation of periphery concrete, long service life.
For solving the problem, the technical solution adopted in the utility model is: comprise the female cylindrical sleeve body of band, at described sleeve body lateral surface with the strip-shaped grooves along described sleeve body axis, be strip projection between adjacent strip-shaped grooves.
Its additional technical feature is:
At the groove of described strip lug surface with closed at both ends;
The two ends of described groove are triangle;
The bottom surface of described groove floor and described strip-shaped grooves is on same periphery;
Be threaded hole at the two ends of described groove, in described screwed hole, be provided with jackscrew screw rod;
At described strip lug surface with circle-shaped cut;
Described strip projection two sides are consistent with the radial direction at this place;
With certain angle between described strip projection two sides and the radial direction at this place.
Bar connecting grooved sleeve provided by the utility model compared with prior art, have the following advantages: one, owing to comprising the female cylindrical sleeve body of band, at described sleeve body lateral surface with the strip-shaped grooves along described sleeve body axis, it is strip projection between adjacent strip-shaped grooves, when operation, spanner is stuck on strip-shaped grooves and strip projection, spanner is not easy to skid, avoid and cause spanner to come off or personnel drop because spanner skids, and strip-shaped grooves is easy and surrounding concrete fixation, avoid because vibration causes concrete to come off, its two, due at the groove of described strip lug surface with closed at both ends, further increase the snap-in force outside spanner and sleeve body, and sleeve body and the concrete adhesive power of periphery strengthen further, its three, the two ends due to described groove are triangle, not only convenient processing, and avoid sleeve body to move axially, its four, because the bottom surface of described groove floor and described strip-shaped grooves is on same periphery, process convenient, they are five years old, owing to being threaded hole at the two ends of described groove, jackscrew screw rod is provided with in described screwed hole, when the internal thread of the thread damage in sleeve body or sleeve body does not mate with screw thread steel, jackscrew screw tip tightly withstands on reinforcing bar, avoids coming off of sleeve body and reinforcing bar, its six, due at described strip lug surface with circle-shaped cut, make the concrete outside sleeve body bonding with sleeve body more firm, its seven, due to described strip projection two sides are consistent with the radial direction at this place or between described strip projection two sides and the radial direction at this place with certain angle, spanner and sleeve body lateral surface are fixing more firm.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model bar connecting grooved sleeve;
Fig. 2 is the lateral plan of bar connecting grooved sleeve;
Fig. 3 is the A-A sectional drawing of Fig. 2;
Fig. 4 is the sectional drawing of the bar connecting grooved sleeve of another kind of strip projection.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the structure of the utility model bar connecting grooved sleeve and use principle are described in further details.
As depicted in figs. 1 and 2, the structural representation of the utility model bar connecting grooved sleeve, the utility model bar connecting grooved sleeve comprises the cylindrical sleeve body 2 with internal thread 1, at sleeve body 2 lateral surface with the strip-shaped grooves 3 along sleeve body 2 axis, be strip projection 4 between adjacent strip-shaped grooves 3.When operation, spanner is stuck on strip-shaped grooves 3 and strip projection 4, and spanner is not easy to skid, and avoids and causes spanner to come off or personnel drop because spanner skids, and strip-shaped grooves easily with surrounding concrete fixation, avoid and cause concrete to come off because vibrating.
Groove 5 on strip projection 4 surface with closed at both ends, further increases the snap-in force outside spanner and sleeve body, and sleeve body and the concrete adhesive power of periphery strengthen further.
The two ends of groove 5 are triangle, not only convenient processing, and avoid sleeve body to move axially.
The bottom surface of groove 5 and the bottom surface of strip-shaped grooves 3, on same periphery, process convenient.
As shown in Figure 3, hole 6 is threaded at the two ends of groove 5, jackscrew screw rod 7 is provided with in described screwed hole, when the internal thread of the thread damage in sleeve body or sleeve body does not mate with screw thread steel, jackscrew screw tip tightly withstands on reinforcing bar, avoids coming off of sleeve body and reinforcing bar.
On strip projection 4 surface with circle-shaped cut 8, make the concrete outside sleeve body bonding with sleeve body more firm.
As shown in Figure 1, strip projection two sides can be consistent with the radial direction at this place, and strip projection two sides also can as shown in Figure 4, and with certain angle between the radial direction at this place, spanner and sleeve body lateral surface fixing more firm.
Protection domain of the present utility model is not only confined to above-described embodiment, as long as structure is identical with the utility model bar connecting grooved sleeve structure, just drops on the scope of the utility model protection.
Claims (8)
