Abstract
The utility model discloses a rebar parallel lap joint electric resistance pressure welding forming electrode. The rebar parallel lap joint electric resistance pressure welding forming electrode comprises an upper electrode and a lower electrode, wherein the lower surface of the upper electrode and the upper surface of the lower electrode are respectively provided with a through groove with the arc-shaped cross section, and the radius of the middle of each through groove is larger than the radius at two ends of each through groove. When the rebar parallel lap joint electric resistance pressure welding forming electrode is used to connect a stirrup, two ends of the stirrup are manufactured into a straight and parallel structure, so that the purpose of saving stirrup materials is achieved, then two ends of the stirrup are put into the through groove of the lower electrode in parallel, lap joint is formed between the two ends, the upper electrode is pressed down and is pressed gradually on the two ends of the stirrup, and finally the two lap joint ends of the stirrup are fused together after the upper electrode and the lower electrode are powered on. In the middle of each through groove, connection parts at two ends of the stirrup are large in diameter, the connection strength at two ends of the stirrup is greatly improved, and the welding quality at two ends of the stirrup is easy to control.
Description
Technical field
The utility model relates to a kind of device of stirrup termination connection of architectural use, relates in particular to a kind of parallel reinforced steel bar overlap resistance pressure welding shaped electrode.
Background technology
At building field; stirrup uses very extensive, and the effect of stirrup is the development in restriction inside concrete crack, improves adhesion strength; can also limit the fracture width that arrives component surface; thereby the raising adhesion strength, therefore, in the anchorage zone of using the larger diameter reinforcing bar; in the lap of splice scope; and when a row reinforcing bar radical arranged side by side is more, because the additional hooping of some is set, to prevent the splitting avalanche of concrete cover.
In the prior art, the processing mode of steel bar end mainly contains following three kinds of modes: the first is that the two ends with stirrup are made into barb and are colluding main reinforcement, then adopt the finer wire colligation, this mode need consume more reinforcing bar, and the installation quality of stirrup is relatively poor; The second is that the two ends with stirrup are made into straight and parallel structure, then adopts the mode of flash butt welding with the two ends docking of stirrup, and this mode easily produces pollution to the bad control of the installation quality of stirrup to air; To be the mode that adopts spot welding connect the two ends of stirrup for the third, the intensity of connection a little less than.
The utility model content
For above shortcomings in the prior art, the utility model provides a kind of material of making stirrup of both having saved, and can improve again stirrup two ends bonding strength, and the quality parallel reinforced steel bar overlap resistance pressure welding shaped electrode that is easy to control.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
Parallel reinforced steel bar overlap resistance pressure welding shaped electrode comprises top electrode and bottom electrode, and the lower surface of described top electrode and the upper surface of bottom electrode are respectively equipped with the groove that cross section is arc, and the radius at described groove middle part is greater than the radius at groove two ends.
As a kind of preferred version of the present utility model, also comprise power on electrode seat and lower electrode holder, described top electrode and bottom electrode are rectangular block, and four jiaos of places of top electrode and bottom electrode are provided with respectively the dormant bolt hole; The described electrode seat that powers on be provided with top electrode on four bolts hole that the dormant bolt hole is corresponding, described top electrode is installed on the electrode seat that powers on by dormant bolt; Described lower electrode holder be provided with bottom electrode on four bolts hole that the dormant bolt hole is corresponding, described bottom electrode is installed on the lower electrode holder by dormant bolt.
The beneficial effects of the utility model are: the utility model is respectively equipped with the groove that cross section is arc at the lower surface of top electrode and the upper surface of bottom electrode, the radius at groove middle part is greater than the radius at groove two ends, when using the two ends of this electrode pair stirrup to connect, only need to be made into the two ends of stirrup straight, and parallel structure, can reach and save the purpose of making the stirrup material, again with in the parallel groove that is placed on bottom electrode in the two ends of stirrup, form certain overlap joint between the two ends, then top electrode is depressed, and be pressed in gradually on the two ends of stirrup, after top electrode and the bottom electrode energising two bond ends of stirrup are merged.At the middle part of groove, the connecting portion at stirrup two ends forms the larger position of diameter, has greatly improved the bonding strength at stirrup two ends, and has been easy to control the welding quality at stirrup two ends.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Shown in Fig. 1～3, parallel reinforced steel bar overlap resistance pressure welding shaped electrode comprises top electrode 1, bottom electrode 2, the electrode seat that powers on 4 and lower electrode holder 5.
Wherein, the upper surface of the lower surface of top electrode 1 and bottom electrode 2 is respectively equipped with the groove 3 that cross section is arc, and the radius at groove 3 middle parts is greater than the radius at groove 3 two ends, as shown in Figure 2.Top electrode 1 and bottom electrode 2 are rectangular block, and four jiaos of places of top electrode 1 and bottom electrode 2 are provided with respectively dormant bolt hole 6.
The electrode seat that powers on 4 is provided with the bolt hole 7 corresponding with four the dormant bolt holes 6 on the top electrode 1, and top electrode 1 is installed on the electrode seat 4 that powers on by dormant bolt.Lower electrode holder 5 is provided with the bolt hole 7 corresponding with four the dormant bolt holes 6 on the bottom electrode 2, and as shown in Figure 3, bottom electrode 2 is installed on the lower electrode holder 5 by dormant bolt.Groove 3 on the top electrode 1 is parallel with the groove 3 on the bottom electrode 2, and in the vertical direction is corresponding.
When using this parallel reinforced steel bar overlap resistance pressure welding shaped electrode that the two ends of stirrup are connected, only need the two ends of stirrup are made into straight and parallel structure, can reach and save the purpose of making the stirrup material, again with in the parallel groove 3 that is placed on bottom electrode 2 in the two ends of stirrup, form certain overlap joint between the two ends, then top electrode 1 is depressed, and is pressed in gradually on the two ends of stirrup, after top electrode 1 and bottom electrode 2 energisings two bond ends of stirrup is merged.At the middle part of groove, the connecting portion at stirrup two ends forms the larger position of diameter, has greatly improved the bonding strength at stirrup two ends, and is easy to control the welding quality at the two ends of stirrup.
