The utility model relates to a fastening type deformed steel bar connecting sleeve, which comprises a main connecting sleeve, a fastening bolt and two square deformed steel bar connecting sleeves which are respectively in threaded connection with the butt ends of the two deformed steel bars, wherein both ends of the main connecting sleeve are provided with square grooves correspondingly matched with the square deformed steel bar connecting sleeves; the square thread connecting sleeve is correspondingly inserted into the square groove, and a plurality of first thread holes are formed in the peripheral side of the square thread connecting sleeve; the main connecting sleeve is provided with a second threaded hole corresponding to each threaded hole in position, and the end part of the screw rod of the fastening bolt is in threaded connection with the second threaded hole and then is in threaded connection and fixation with the first threaded hole.
In order to stably connect the fastening screw thread on the main connecting sleeve, two end openings of the threaded hole on the outer side wall of the main connecting sleeve are provided with groove bodies, and the bottom surface of the bolt head of the fastening bolt is tightly attached to the bottom surface of the groove bodies.
The closed end face of the square thread connecting sleeve designed for pre-positioning the two square thread connecting sleeves after being respectively inserted into the two square grooves is provided with a convex block, the bottom of each square groove is provided with a groove correspondingly matched with the convex block, and the convex block is correspondingly inserted into the groove.
The fastening bolt designed for improving the connection strength between the two sections of deformed steel bar end parts is a 45# steel fastening bolt; the main connecting sleeve is a 45# steel main connecting sleeve; the square thread connecting sleeve is a 45# steel square thread connecting sleeve; after the butt joint, welding is needed, and after the welding is finished, the outer side walls of the main connecting sleeve, the square thread connecting sleeve and the welded joint are coated with a layer of anti-rust layer, so that the phenomenon of rusting is avoided, the service performance after the butt joint is improved, and the service life is prolonged.
In order to facilitate the square thread connecting sleeve to be inserted into the square groove, the edge of the notch of the square groove and the edge of the end face of the square thread connecting sleeve are both provided with chamfer angles.
The utility model discloses a tightly decide formula screw-thread steel connecting sleeve inserts in the square hole of main adapter sleeve through connecting the square thread adapter sleeve at the twisted steel tip to fix the butt joint of linking to each other through tightly deciding the bolt, promote the speed that multistage twisted steel carries out mutual butt joint, improve the efficiency of construction, only need a workman can carry out comparatively light butt joint, reduced construction cost (cost of labor), also reduce workman intensity of labour, also need not rotatory reinforcing bar in the connection. Two layers of connecting sleeves are adopted for butt joint, the problem that the butt joint strength is insufficient due to the fact that only a single connecting sleeve is adopted in the prior art is solved, and the butt joint strength is further improved.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art all belong to the protection scope of the present invention.
Example 1:
as shown in fig. 1 and fig. 2, the fastening type screw steel connecting sleeve described in the present embodiment includes a main connecting sleeve 20, a fastening bolt 30, and two square screw connecting sleeves 10 screwed to the butt ends of two screw steels, respectively, and both ends of the main connecting sleeve 20 have square grooves 203 correspondingly matching the shapes of the square screw connecting sleeves 10; the square threaded connecting sleeve 10 is correspondingly inserted into the square groove 203, and the periphery of the square threaded connecting sleeve is provided with a plurality of first threaded holes 101; the main connecting sleeve 20 is provided with a second threaded hole 201 corresponding to the first threaded hole 101, and the end of the screw rod of the fastening bolt 40 is in threaded connection with the second threaded hole 201 and then is in threaded connection and fixation with the first threaded hole 101. In the structure, the internal thread hole of the square thread connecting sleeve is connected with the external thread section at the end part of the threaded steel bar in a threaded manner for fixed installation, and after the square thread connecting sleeve is correspondingly inserted into the square groove, the outer side wall of the square thread connecting sleeve is clung to the inner side wall of the square groove so as to improve the compactness of the structure; the outer port of the threaded hole of the outer side wall of the main connecting sleeve is provided with a groove body, and the bottom surface of the bolt head of the fastening bolt is tightly attached to the bottom surface of the groove body.
