Abstract
The utility model relates to an upsetting steel bar connector, which comprises two steel bars. In addition, the end head of the steel bar is upsetting. The connector is composed of a sleeve barrel and a bulkhead provided with a perforation. The sleeve barrel and the bulkhead are respectively penetrated and sheathed on the two steel bars, and the upsetting ends of the two steel bars are uniformly positioned in the sleeve barrel and the bulkhead are provided with an inner and an outer screw thread which are corresponding to each other and are connected in the form of screw connection, wherein, the bulkhead can be a T type, or the bulkhead can be provided with an end with an enlarged inner diameter and the inner part of the bulkhead is provided with the inner screw thread is screwed and combined inside or outside the sleeve barrel, and one or two bulkheads can be arranged. The utility model has the advantages of small equipment investment, simple and convenient installation, high quality, easy control, and low cost, and in addition, the joint strength of the utility model ca reach the limit strength of a parent metal of the steel bar.
Description
The utility model relates to a kind of for the reinforcing bar connector that uses in the builing industry, refers to a kind of upset reinforcing rebar connector especially.
In the prior art, the following several modes of the normal employing of the connection of building iron: taper thread connects; Straight thread connects; Cold extrusion connects.The weak point of these three kinds of connected modes is:
(1) taper thread processed complex, installing to tighten needs special-purpose torque-indicating wrencg, the difficult control of quality, and bonding strength does not reach the ultimate strength of parent material of reinforcement rebar.
(2) straight thread connection device costliness is perishable, and the centering difficulty is installed.
(3) the cold extrusion connection device has high input, and extrusion speed is slow, the cost height.
The utility model purpose is at the deficiencies in the prior art, and it is simple to provide a kind of use to install, bonding strength height, the upset reinforcing rebar connector of low cost of manufacture.
For achieving the above object, a kind of upset reinforcing rebar connector of the utility model, the reinforcing bar that comprises two butt head jumping-ups, it is characterized in that: this connector is made up of sleeve and the plug that is provided with perforation, sleeve and plug are set in respectively on two reinforcing bars, and the upset end of two reinforcing bars all places in the sleeve, and sleeve and plug are established corresponding internal and external threads and be screwed together together.
Wherein, sleeve one end internal diameter dwindles and forms the ring bank that restriction steel bar thick end is deviate from, and end is established internal thread in addition, with the external thread spiro fastening of plug.
Above-mentioned plug can be the T type, screws togather and leave a ring edge that is not screwed in the sleeve with sleeve, but the supplier just plug and sleeve screw togather operation.
The utility model can also be implemented by following dual mode:
(1) be provided with two the externally threaded T type of tool plugs, the sleeve with two ends tool internal thread screws togather and leaves the ring edge that is not screwed in the sleeve respectively.
(2) the sleeve two ends are provided with external screw thread, and the plug tool enlarges the internal diameter end and establish internal thread in it, is screwed together in outside the sleeve.
The utility model is to certain size when using with two end reinforced jumping-ups (cold-heading or heat are upset), utilize single plug of outer (or interior) screw thread of tool or two plug corresponding with tool in the sleeve of (or outer) screw thread be set in and also screw togather mutually on the reinforcing bar and upset reinforcing rebar is linked together, reinforcing bar and sleeve form the reinforcing bar jointing by bearing shearing resistance, have and the equicohesive combined structure of parent material of reinforcement rebar thereby the joint of formation is reached.
The utility model has the advantages that: the equipment less investment, need not carry out screw thread processing behind the steel bar thick, to install simple and conveniently, the quality height is controlled easily, and cost is low, and bonding strength can reach the ultimate strength of parent material of reinforcement rebar.
The utility model is described in further detail to lift several preferred embodiments below in conjunction with accompanying drawing.
Fig. 1 is preferred embodiment one of the present utility model.
Fig. 2 is preferred embodiment two of the present utility model.
Fig. 3 is preferred embodiment three of the present utility model.
Fig. 4 is preferred embodiment four of the present utility model.

At first see also shown in Figure 1, a kind of upset reinforcing rebar connector of the utility model, the reinforcing bar S that comprises two butt head jumping-ups, S ', this connector is made up of sleeve 1 and the plug 2 that is provided with perforation, sleeve 1 and plug 2 are arranged in two reinforcing bar S respectively, on the S ', and the upset end S1 of two reinforcing bars, S1 ' all places in the sleeve 1, wherein, sleeve one end internal diameter dwindles and forms the ring bank 3 that restriction steel bar thick end is deviate from, end is established internal thread in addition, plug is the T type and establishes the tool external screw thread, and sleeve 1 and plug 2 utilize set corresponding internal and external threads to be screwed together together, and plug 2 also leaves a ring edge 4 that is not screwed in the sleeve 1.This ring edge 4 can supply the spanner clamping when plug 2 and sleeve 1 screw togather operation, smoothly very convenient to use.
See also Fig. 2, preferred embodiment two of the present utility model, among this embodiment, sleeve is made as straight barrel type, and two ends screw togather shutoff by T type plug 2.
See also Fig. 3, preferred embodiment three of the present utility model, among this embodiment, sleeve 1 two ends are provided with external screw thread, and two plugs, 2 ' tool enlarges the internal diameter end and establish internal thread in it, and utilization wears two reinforcing bar S, S ' and is screwed together in sleeve 1 two ends respectively.
See also Fig. 4, preferred embodiment four of the present utility model is among this embodiment, sleeve 1 one ends form the ring bank 3 that restriction steel bar thick end S1 ' deviates from embodiment one, and end forms external screw thread in addition, and adopt the plug 2 ' among the embodiment three to construct, make plug 2 ' be screwed together in sleeve 1.
The above only is several preferred embodiments of the present utility model, be not in order to enforcement of the present utility model is done any pro forma restriction, those skilled in the art replace according to the element that architectural feature of the present utility model obviously can be done multiple equivalence, but should be noted that these all should be included in the technical solution of the utility model scope.
