By using above-mentioned technical proposal, when support rod is inserted into fixing groove, support rod is fixed together with superimposed sheet, into one
Stirrup one is fixed in step.
Further, it is fixedly connected with auxiliary rod on the support rod, is mutually perpendicular between the auxiliary rod and support rod,
The auxiliary rod is located in reinforcement tank.
By using above-mentioned technical proposal, when concreting is into reinforcement tank, concrete can squeeze support rod, increase
If auxiliary rod, the degree of support rod stress deformation is effectively reduced.
Further, one knee of stirrup is arranged with stirrup two corresponding with stirrup one.
By using above-mentioned technical proposal, stirrup two is located in cast-in-place concrete, effectively increase stirrup one and concrete it
Between contact area, guarantee the bearing strength of cast-in-place concrete layer.
Further, cross bar is fixedly connected at the V-bend of the stirrup two.
By using above-mentioned technical proposal, make to connect between stirrup one and stirrup two stronger.
Further, two both ends of stirrup are integrally formed with extension rod.
By using above-mentioned technical proposal, the contact area between stirrup two and concrete is further increased, is guaranteed cast-in-place
The bearing strength of concrete layer.
In conclusion the utility model has the following beneficial effects:
1, pregroove marks are opened up on superimposed sheet ontology, when concreting enters preformed groove, after concrete setting, with overlapping
Connection area increases between plate, and connection is closer, more abundant, thus greatly strengthens its shock resistance；
2, one knee of stirrup is arranged with stirrup two corresponding with stirrup one, when stirrup two is located in cast-in-place concrete,
The contact area between stirrup one and concrete is effectively increased, guarantees the bearing strength of cast-in-place concrete layer.
