Abstract

The utility model discloses a connecting device, which can fix screw-thread steel bars together, and solves connecting problems at construction site. The utility model comprises two half bodies of a protecting holder, which are used for holding screw-thread steel bars, and the inner walls of the two half bodies of the protecting holder is in a shape matched with the outer shape of a screw-thread steel bar. A sleeve is respectively arranged on the outer parts of the two half bodies of the protecting holder. Two ends of a sleeve are provided with a plurality of open slots, and the sleeve with open slots is provided with pipe threads which are in fit connection with nuts. The nuts on the sleeve are screwed, and both ends of the sleeve correspondingly tighten and hold the half bodies of the protecting holder firmly, so that two screw-thread steel bars can be connected into integration.

Description

The Deformed Steel Bars joiner

The utility model discloses a kind of coupling arrangement that Deformed Steel Bars is fixed together.

At present, often use reinforced concrete construction in construction engineering, wherein Deformed Steel Bars is extensive use of to strengthen the intensity of structure, because the particularity of building self structure, concrete then is in layer or partly cast, and the setting of Deformed Steel Bars also is that the progress according to engineering adds in batches.In the prior art, the connection of Deformed Steel Bars is then welded by modes such as butt welding, joint welding, adopts the mode of welding to connect, operator need pass through professional training, the welding also need special device, and be required to be operator provide the welding the place, therefore, adopt the mode of welding time-consuming.

The purpose of this utility model is to design a kind of with the correct each other joiner that is fixedly connected of Deformed Steel Bars.

For achieving the above object, the technical solution adopted in the utility model is: a kind of Deformed Steel Bars joiner, it comprises two retaining clip halfbodies that are used for the clamping Deformed Steel Bars, its inwall is provided with the groove that conforms to the Deformed Steel Bars profile, there is sleeve pipe two retaining clip halfbody outsides, the two ends of sleeve pipe are provided with some opening slots, and opening slot is along its end face symmetric arrangement, and the sleeve pipe at place, opening slot position is provided with pipe thread and nut is connected.

Two retaining clip halfbodies that are used for the clamping Deformed Steel Bars of the utility model design, two Twisted Steel enemies put together the back and with the retaining clip halfbody its assembly are close together, turn the nut on the sleeve pipe, two of sleeve pipe is tightened up relatively and the retaining clip halfbody is clamped firmly, thereby two Deformed Steel Barss are connected as one.

Description of drawings

Fig. 1 is an assembly structure schematic representation of the present utility model;

Fig. 2 is the A--A sectional view among Fig. 1;

Fig. 3,6 is respectively the structural representation of retaining clip halfbody, sleeve pipe.

Fig. 4,6 is respectively Fig. 3,5 left view.

The utility model is described in further detail below in conjunction with drawings and Examples.

Embodiment

As Fig. 1,2,3, shown in 4, the retaining clip halfbody (10) that is used for the clamping Deformed Steel Bars, (20) structure shape is basic identical, both can be with the Deformed Steel Bars retaining clip betwixt, as Fig. 1, shown in 2, retaining clip halfbody (10), (20) inwall is provided with groove (11), (21), they conform to the Deformed Steel Bars shape, retaining clip halfbody (10), (20) after retaining clip is lived Deformed Steel Bars, its outside is with sleeve pipe (30), as Fig. 5, shown in 6, the two ends of sleeve pipe (30) are equipped with some opening slots (31), opening slot (31) is along its end face symmetric arrangement, a common end is provided with 4 opening slots (31), and the position at opening slot (31) place is provided with pipe thread (32) and is connected with nut (40).When fastening nut (40), owing to be pipe thread, two ends because of sleeve pipe (30) are provided with opening slot (31) simultaneously, therefore, sleeve pipe (30) is because of stressed two Deformed Steel Barss that tighten up and two retaining clip halfbodies (10), (20) are clamped tightly correct placement, the Deformed Steel Bars of two velamen clampings can't be separated from one another under groove (11) set on retaining clip halfbody (10), (20) inwall, (21) effect, thereby realize connecting the purpose of Twisted Steel.Because during fastening nut (40); slightly close up and dwindle in sleeve pipe (30) two ends; its inwall two ends are rendered as taper; for making sleeve pipe (30) and retaining clip halfbody (10); (20) outer wall end is fastening reliably; with two retaining clip halfbodies (10); (20) two ends are designed to tapering surface (12); referring to Fig. 3; and make it to conform to the tapering of pipe thread (32); thereby guarantee retaining clip halfbody (10); (20) be fixed on reliably in the sleeve pipe (30); therefore; it is convenient that the utility model connects Deformed Steel Bars; reliably; for guaranteeing two retaining clip halfbodies (10); (20) Twisted Steel is therebetween clamped two retaining clip halfbodies (10); (20) cross section all is slightly less than semicircle, i.e. the slit is arranged during clamping between the two; as Fig. 2; shown in 4, so that leave the sufficient room of pretension during both clamping Twisted Steels.

Claims

1. Deformed Steel Bars joiner, it is characterized in that: it comprises two the retaining clip halfbody (10), (20) that are used for the clamping Deformed Steel Bars, be respectively equipped with the groove (11), (21) that conform to the Deformed Steel Bars shape on its inwall, there is sleeve pipe (30) two retaining clip halfbodies (10), (20) outside, the two ends of sleeve pipe (30) are equipped with some opening slots (31), opening slot (31) is along its end face symmetric arrangement, and the position at opening slot (31) place is provided with pipe thread (32) and is connected with nut (40).

2. Deformed Steel Bars joiner according to claim 1 is characterized in that: the two ends of two retaining clip halfbodies (10), (20) are tapering surface, and its tapering conforms to the tapering of pipe thread (32).
