Abstract
The utility model relates to a screw steel bar connector. The utility model is composed of a pair of clamping plates of a screw steel bar which is buckled and connected and fastening caps which are impacted are respectively sheathed on two end heads of the clamping plates. The inner sides of the clamping plates are respectively provided with crescent grooves and saw teeth which are engaged with the shape of the screw steel bar. The screw steel bar connector makes the butt joint of steel bar is frim and reliable. The utility model has the advantages of convenient operation, high speed and low cost. The utility model is suitable for specializaiton, standardizaiton and seriation production.
Description
The utility model relates to a kind of indented bars linkage, particularly indented bars connector.
At present, it is that 97219497.5 coarse-pitch thread steel is to connecting bolt that known indented bars linkage has the patent No., it is by a pair of nut, the clamping plate of one pair cross-section semicircular in shape are formed, its clamping plate inboard is provided with the groove that matches with indented bars outside screw thread form, and two, the clamping plate outside is respectively equipped with the external screw thread that is complementary with nut, and connection speed is slow when coming the connecting thread steel with it, inconvenient operation, fastness is relatively poor.Also has a kind of reinforcing bar connector, it comprises the taper button that two identical conical plates are identical with two, two butts that are connected reinforcing bar are placed in the conical plate, another piece conical plate closes, pack into the taper button at two and tack conical plate, compress the taper button with hydraulic machinery again, its conical plate inboard is provided with the groove that matches with indented bars outside screw thread form, come the connecting thread reinforcing bar easily to produce dislocation with it, the reliability of influence butt joint.
The purpose of this utility model provides a kind of indented bars connector, accomplishes that connection speed is fast, and is easy to use, docks solid and reliable.
The purpose of this utility model realizes by following approach, this indented bars connector clamping plate that outer shape is identical and two is tapered by circle in the tapered fastening cap in the indented bars that is connected by two velamens and two inboards and two are formed, two clamping plates fastens connected two indented barss, and the two ends of two clamping plates puts and compress fastening cap respectively.It is characterized in that wherein the inboard of clamping plate is provided with the crescent that matches with the indented bars profile, and the inboard of another piece clamping plate is set to saw the shape tooth.
The utility model compared with prior art has following characteristics: because the inboard of two clamping plate is set to respectively saw shape tooth and crescent, thereby make the reinforcing bar butt joint solid and reliable.Since the fastening cap of this connector and cleat design is ingenious and can adopt specialization, standardization, producing in serial form, thereby cost is low, highly versatile, easy to use, connection speed is fast.
Fig. 1 is provided with the cross section structure schematic diagram of crescent and saw shape tooth respectively for the utility model two clamping plates inboard.
The sectional structure chart of the clamping plate of Fig. 2 when establishing crescent and being with fastening cap in the utility model.
Fig. 3 all is set to saw the cross section structure schematic diagram of shape tooth for the utility model two clamping plate inboards.
Fig. 4 is the cross section structure figure of the utility model fastening cap.
Fig. 5 is provided with crescent and the alternate cross section structure schematic diagram of saw shape tooth for the utility model clamping plate inboard.
Now the utility model is described in further detail with embodiment with reference to the accompanying drawings.
Embodiment one: as Fig. 1, Fig. 2, shown in Figure 4, the utility model comprises and is connected indented bars 9,10, pair of inside be conical fastening cap 1,4 with one pair in circle and outer shape is identical and two is the clamping plate 2,3 of conical termination 6, the inboard of its middle clamp plate 2 is provided with the crescent 7 that matches with the indented bars profile, and the inboard of clamping plate 3 is set to saw shape tooth 5.
Embodiment two: as shown in Figure 3, present embodiment and embodiment one are basic identical, and difference is that the inboard of clamping plate 2 also is set to saw shape tooth 8.
Embodiment three: as shown in Figure 5, present embodiment and embodiment one are basic identical, and difference is that the clamping plate 2 and the inboard of clamping plate 3 are provided with the crescent 7 that matches with the indented bars profile, and are provided with saw shape tooth 11 between every adjacent two crescents 7.
The circular arc radian sum of above-mentioned two clamping plates 2,3 is less than 2 π.
The tapering that above-mentioned fastening cap 1,4 is conical inboard is identical with the tapering of conical termination 6.
Above-mentioned inboard is conical fastening cap 1,4 and also can be made into a pair of nut, and the threaded threaded end that can be connected with the nut spiral is made in the conical termination 6 at clamping plate two ends.
During use, fastening cap 1,4 is through on two indented barss that need butt joint respectively earlier, and make the big end of taper hole of fastening cap 1,4 relative, two butts that will be connected indented bars again are placed in the clamping plate, another piece clamping plate close, on the conical termination 6 at two, pack into fastening cap 1,4 and tack clamping plate, with hydraulic machinery fastening cap 1,4 is pushed in the middle of joint simultaneously from the outside then, when the spacing between two fastening caps 1,4 reaches preliminary dimension, can satisfy the tensile strength requirement that is connected indented bars 9,10.
