Fig. 1 is the planar structure schematic diagram of the utility model；
Fig. 2 is the schematic perspective view of the utility model；
Fig. 3 is the structural schematic diagram of reinforcing bar connector in Fig. 1.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing and by specific embodiment, and following embodiment is only retouched
The property stated, it is not restrictive, protection scope of this utility model cannot be limited by this.
A kind of new reinforcing steel bar connection structure convenient for reinforcing bar connection, referring to Figure 1-3, practical novel point are as follows:
Including reinforcing bar connector 3, reinforcing bar connector is the trapezoidal shape structure that four sides steel plate is constituted, the inside of reinforcing bar connector
For with the matched trapezoidal connection space 3-2 of outer profile, reinforcing bar connector short side medium position and long side medium position distinguish
It is provided with the first reinforcing bar mounting hole 3-1 and the second reinforcing bar mounting hole 3-3, the end of two reinforcing bars is each passed through the reinforcing bar on both sides
Mounting hole, and by be placed in trapezoidal connection space respectively with the first nut 2 of two end reinforced connections and the second nut 4 and steel
Muscle connector is connected.Two sections of reinforcing bars are linked together by the both sides of reinforcing bar connector, reinforcing bar connector plays two sections
The effect of stress transfer between reinforcing bar.
Formed by integrally casting molding structure or welding fabrication structure can be used in above-mentioned reinforcing bar connector.Formed by integrally casting molding structure needs
Prefabricated mould to be wanted, is relatively specific for producing in enormous quantities, has the advantages that shear behavior is good, welding fabrication structure saves mold,
Suitable for the production of small lot, but shear behavior is good not as good as formed by integrally casting molding structure.
