Abstract

The utility model relates to a connector for reinforced bars, comprising a fixed sleeve and a fastening sleeve. One end of the fixed sleeve is a combined end, and the other end is a sealed fixed end. The inner side of the combined end of the fixed sleeve is provided with a combined thread hole which is outwards and gradually enlarged; simultaneously, the outer side of the combined end is provided with an oblique cone surface; the combined end is axially provided with cutting joints which are uniformly arranged; the outer side of the fixed sleeve is provided with a fastening convex ring, and the inner side of the fastening sleeve is provided with an oblique cone hole with larger taper. When the connector for reinforced bars is used, the fixed end of the fixed sleeve is welded and fixed on a steel beam; simultaneously, force is applied through the fastening convex ring on the outer side, and the reinforced bars are continuously connected through the fastening sleeve.

Description

Reinforced bar welder

The utility model relates to a kind of steel bar connector, and it is combined by a fixed muffle and packing cover, and can be in order to reinforcing bar is done laterally to be connected with girder steel or other structures.

General existing steel bar connector all is thread cuttings on end reinforced, in continued access device inside screwed hole is set simultaneously, can combine with the screwed hole of the inner setting of continued access device by the end of thread of reinforcing bar.But this kind structure in conjunction with the time and can't obtain suitable bond strength, simultaneously when utilization often in the screwed hole because of the stressed end of thread fracture continued access device that makes reinforcing bar.

Main purpose of the present utility model is: a kind of steel bar connector is provided, this steel bar connector can be used for reinforcing bar is done laterally to be connected with girder steel or other structure, its bond strength height can rupture in the screwed hole of continued access device the end of thread of reinforcing bar when utilization.

The utility model provides a kind of steel bar connector, it is combined by a fixed muffle and packing cover, one end of fixed muffle is the combination end with steel bar joining, and the other end is the stiff end of sealing, combination end inboard at fixed muffle is provided with the combination screwed hole that enlarges gradually to the end, the combination end outside is provided with to the diminishing scalene cone in end, on this combination end, offer the axial joint-cutting that multiple tracks all distributes simultaneously, be provided with a ring packing bulge loop in addition in the outside of fixed muffle, the packing cover then is a ring body, side is that a tapering is than the bigger tilted prick hole of fixed muffle combination end scalene cone tapering within it, the fixed muffle stiff end is welded in the girder steel side, the screw thread steel end is assembled in the combination end combination screwed hole, the packing bulge loop that cooperates the fixed muffle outside again with the oil pressure facility, and packing is overlapped on the scalene cone that packing is bonded to fixed muffle combination end.

Further specify architectural feature of the present utility model and purpose below in conjunction with accompanying drawing.Brief Description Of Drawings is as follows:

Fig. 1 is that element of the present utility model decomposes cross-sectional schematic.

Fig. 2 is a combination cross-sectional schematic of the present utility model.

See also shown in Figure 1, it is an element decomposing schematic representation of the present utility model, can see the detailed structure of each member of the utility model thus among the figure, be combination end 11 at its fixed muffle 10 1 ends, and the other end is the stiff end 12 of sealing, be provided with the combination screwed hole 13 that enlarges gradually to the end in combination end 11 inboards, and be provided with to the diminishing scalene cone 14 in end in combination end 11 outsides, on this combination end 11, offer the equally distributed axial joint-cutting 15 of multiple tracks simultaneously, be provided with a ring packing bulge loop 16 in addition in the outside of the utility model fixed muffle 10; 20 in packing cover of the present utility model is a ring body, and side is that a tapering is than the bigger tilted prick hole 21 of fixed muffle 10 combination end 11 scalene cones, 14 taperings within it.

Cooperate the utility model combination cross-sectional schematic of Fig. 2 to see it, when can more understanding the mode that relevant the utility model is implemented in depth, when utilization steel bar connector of the present utility model, be that first stiff end 12 with fixed muffle 10 is welded in girder steel 40 sides, fixed muffle 10 can not weld earlier with after reinforcing bar 30 ends of thread 31 combine again, because the length of reinforcing bar 30 is quite long, if earlier the end of thread 31 combinations of reinforcing bar 30 are fixed in the combination screwed hole 13 of fixed muffle 10, then will inevitably have influence on the weld job of fixed muffle 10, then again reinforcing bar 30 ends of thread 31 are assembled in the combination screwed hole 13 of fixed muffle 10 combination ends 11, cooperate packing cover 20 and packing bulge loop 16 to carry out clamping by the oil pressure facility more at last, and packing cover 20 is assembled on the combination end 11 of fixed muffle 10, and come the scalene cone 14 on the fixed muffle 10 combination ends 11 is carried out packing by the tilted prick hole 21 of packing cover 20, so can reach reinforcing bar 30 horizontal continued accesses in the effect of girder steel 40 sides.

By above explanation as can be known, structure configuration mode of the present utility model can provide reinforcing bar 30 and girder steel 40 or other similar structures to do the effect of horizontal integration really, and can make the scope of application of this type of steel bar connector wider, it is available simultaneously also can to allow building industry or relevant dealer can have better structure, and can improve the structural strength of monolithic architecture thing.

Claims

1, a kind of steel bar connector, it is combined by a fixed muffle and packing cover institute, and an end of fixed muffle be the combination end with steel bar joining, and the stiff end of the other end for sealing, combination end inboard at fixed muffle is provided with the combination screwed hole that enlarges gradually to the end, it is characterized in that:

The combination end outside is provided with to the diminishing scalene cone in end, offers the axial joint-cutting that multiple tracks all distributes simultaneously on this combination end, is provided with a ring packing bulge loop in addition in the outside of fixed muffle,

The packing cover then is a ring body, and side is that a tapering is held the bigger tilted prick hole of scalene cone tapering than the fixed muffle combination within it,

The fixed muffle stiff end is welded in the girder steel side, and the screw thread steel end is assembled in the combination end combination screwed hole, cooperates the packing bulge loop in the fixed muffle outside again with the oil pressure facility, and packing is overlapped on the scalene cone that packing is bonded to fixed muffle combination end.
