Description
Technical field
The utility model relates to a kind of architectural engineering accessories fields more particularly to one kind can weld positive and negative screw-thread straight thread
Sleeve.
Background technique
Straight screw sleeve is the steel sleeve for transmitting the reinforcing steel bar machinery connector of reinforcing bar axial tension or pressure.Straight screw sleeve
It is divided into direct rolling straight thread sleeve, rib-stripped and rolled straight screw sleeve and upsetting straight sleeve.
Existing straight screw sleeve majority is to offer straight thread in sleeve on the market, can not determine both ends steel when in use
Muscle is separately connected the distance in sleeve, and when two end bars are to be connected to active position, will cause bushing core cavity, drop
Low-intensity.It is also possible to swing with reinforcing bar after the completion of connection and rocks the connection distance for reducing sleeve and reinforcing bar, the company of reducing
Connect intensity.
Utility model content
The purpose of this utility model is to provide one kind can weld positive and negative screw-thread straight screw sleeve, to solve above-mentioned background
The problem of being proposed in technology.
To achieve the above object, the utility model provides the following technical solutions:
One kind can weld positive and negative screw-thread straight screw sleeve, including partition, front sleeve, after sleeve, reinforce pawl, groove, just
Threaded hole, left-hand thread hole, frustum groove, the partition rear and front end is respectively integrally formed with front sleeve and after sleeve, before described
Plus thread hole and left-hand thread hole are offered in sleeve and after sleeve respectively, the plus thread hole and left-hand thread hole inside are in partition
On offer frustum groove, integrally formed with eight reinforcings pawls, the reinforcing pawl outside on the outside of the front sleeve and after sleeve
Groove is offered from outside to inside, and the plus thread hole and left-hand thread hole are threaded with matching splice and add
Gu pawl can by groove with to realize that the reinforcing bar being threadedly coupled is welded.
It is preferred: screw thread identical with plus thread hole screw pitch to be offered on the inside of the reinforcing pawl on the front sleeve, after described
Offer screw thread identical with left-hand thread hole screw pitch on the inside of reinforcing pawl on sleeve, the bevel angle between 50 ° to 70 °,
Frustum groove top surface diameter is the half of basal diameter.
Preferred: the partition, front sleeve, after sleeve and reinforcing pawl are all made of No. 45 steel of national standard.
The beneficial effects of the utility model are: the utility model structure is simple, rationally, positive and negative screwed connection reinforcing bar is or not design
It easily loosens and easy for installation, partition can effectively increase sleeve strength, reinforce pawl and reinforcing bar welds enhancing bonding strength again.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that the utility model can weld positive and negative screw-thread straight screw sleeve；
Fig. 2 is the schematic diagram of internal structure that the utility model can weld positive and negative screw-thread straight screw sleeve.
In figure: 1, partition, 2, front sleeve, 3, after sleeve, 4, reinforcing pawl, 5, groove, 6, plus thread hole, 7, left-hand thread hole,
8, frustum groove.
Specific embodiment
The utility model is further elaborated in the following with reference to the drawings and specific embodiments:
As shown in Figs. 1-2, one kind can weld positive and negative screw-thread straight screw sleeve, including partition 1, front sleeve 2, after sleeve 3,
Pawl 4, groove 5, plus thread hole 6, left-hand thread hole 7, frustum groove 8 are reinforced, 1 rear and front end of partition is respectively integrally formed with preceding
Sleeve 2 and after sleeve 3 offer plus thread hole 6 and left-hand thread hole 7, the positive spiral shell in the front sleeve 2 and after sleeve 3 respectively
Pit 6 and 7 inside of left-hand thread hole offer frustum groove 8 on partition 1, and the front sleeve 2 and 3 outside of after sleeve are integrated
Eight reinforcing pawls 4 are formed, 4 outside of reinforcing pawl offers groove 5, the plus thread hole 6 and left-hand thread from outside to inside
Hole 7 be threaded with matching splice and reinforce pawl 4 can by groove 5 with realize the reinforcing bar being threadedly coupled into
Row welding.Screw thread identical with 6 screw pitch of plus thread hole, the after sleeve 3 are offered on the inside of reinforcing pawl 4 on the front sleeve 2
On reinforcing pawl 4 on the inside of offer screw thread identical with 7 screw pitch of left-hand thread hole, 5 angle of groove is between 50 ° to 70 °, institute
State the half that 8 top surface diameter of frustum groove is basal diameter.The partition 1, front sleeve 2, after sleeve 3 and reinforcing pawl 4 are equal
Using No. 45 steel of national standard.
The utility model application method: the plus thread hole 6 and left-hand thread hole 7 passed through on front sleeve 2 and after sleeve 3 respectively connects
Matching steel bar end is connect, the lower material head on splice top is connected by frustum groove 8, is passed through again after the completion of being threadedly coupled
The groove 5 reinforced on pawl 4 will reinforce pawl 4 and reinforcing bar carries out groove butt welding and realizes welding.
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and
And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this is practical new in other specific forms
Type.Therefore, the same variation in all respects, the embodiments should be taken as exemplary, therefore in equivalency range
