Abstract
The utility model relates to a steel bar linkage sleeve, which is designed according to the outside shape of the steel bar. The cross section of the inside hole of the sleeve is oval-shaped with ear grooves arranged on both sides of the main body hole. The utility model has the advantages that the utility model has a novel structure, is easy to produce and use with a tight linkage, a large joint surface, a high anti-pulling and anti-torsion strength as a novel steel bar linking device.
Description
Technical field
The utility model belongs to a kind of reinforcing bar connector in the technical field of buildings, especially a kind of reinforcing steel bar connecting sleeve tube.
Background technology
Along with the continuous development of builing industry, the quality of connection of reinforcing bar is directly connected to construction work.In known technology, the reinforcing steel bar connecting sleeve tube that has now in construction work to be adopted mainly contains be threaded sleeve and circular pipe type extruding branch sleeve.Screw shell is to be shaped on internal thread in sleeve body, steel bar end is made external screw thread and is docked and screw fastening with the screw thread steel branch sleeve, its process procedure is complicated, the processing cost height, and the circular pipe type branch sleeve is to be connected with the steel bar cold rolling extruding, it is big that the reinforcing bar of positive circular hole of sleeve and band convex tendon is joined the company gap, horizontal bar portion contact bonded area is little, the residual hole of convex tendon groove is many, connects and has hidden danger, also makes troubles to building operations.
Summary of the invention
In order to overcome the deficiencies in the prior art, the new reinforcing steel bar branch sleeve that the utility model provides a kind of and constructs novelty, connects is easy, connect closely, intensity is high, be convenient to construct.
The technical scheme in the invention for solving the technical problem is: at the reinforcing bar outline body is the reinforcing bar that there are band convex tendons such as the crescent horizontal bar reinforcing bar on symmetrical convex tendon limit or herringbone convex tendon reinforcing bar both sides.Tubular sleeve cylindrical shell endoporus is made for the special-shaped through hole sleeve that there is symmetrical wing lug groove ellipticity or oblate shape main hole both sides.During use, two steel bar ends of required connection are inserted in the branch sleeve endoporus relatively, sleeve inner hole wall and band convex tendon reinforcing bar outline body are matched, form transition or interference tight fit, block sleeve body with compression tool again and apply extruding external force, make sleeve body radially produce plastic strain, the crescent moon horizontal bar of reinforcing bar or herringbone convex tendon muscle groove are metal filled by what flow in the sleeve distortion simultaneously, closely two reinforcing bars are solidly fixed, just can be used for construction work.
Owing to the utility model is the branch sleeve of the band symmetry wing lug abnormity through hole that designs of the reinforcing bar outline body of corresponding band convex tendon, it is compared with technology has following beneficial effect, structure is novel, design innovation, can directly adopt roll process, hot extrusion method, hubbing once to make, processing and easy to use, especially in the sleeve hole shape match with it the band convex tendon that connects reinforcing bar outward the bodily form match, after extruding connects admittedly, bonded area is big, the residual hole of fit clearance is minimum, anti-axial tension and anti-torsional strength height, quality of connection is good, is a kind of novel reinforcing bar connector spare.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a concrete constructional drawing of the present utility model.
Fig. 2 is the sectional view of the A-A of Fig. 1.
Fig. 3 is the sectional drawing of Fig. 1 along the B-B line.
Fig. 4 is that the utility model connects the instance graph of reinforcing bar admittedly.
The specific embodiment
Embodiment as shown in Figure 1, the utility model are that pipe shape sleeve cylindrical shell 1 is made for cross section is ellipticity main hole 2 and the special-shaped through hole sleeve that is shaped on vertical wing lug groove 3 in bilateral symmetry.Or sleeve is that cylindrical shell 1 cross section is the irregularly-shaped hole sleeve that perpendicular oblate shape main hole horizontal axis bilateral symmetry is shaped on the wing lug groove.
Claims (2)
1, a kind of reinforcing bar connects special-shaped sleeve, comprises the tubular casing cylindrical shell, it is characterized in that sleeve is that cylindrical shell (1) endoporus cross section is ellipticity main hole (2) and the sleeve that is shaped on the special-shaped through hole of symmetrical wing lug groove (3) in both sides.
2, reinforcing steel bar connecting sleeve tube according to claim 1 is characterized in that sleeve is that cylindrical shell (1) endoporus cross section is the sleeve that perpendicular oblate shape main hole horizontal axis both sides are shaped on the special-shaped through hole of symmetrical wing lug groove.
