For solving the problems of the technologies described above, the technical solution adopted in the present invention is: the overall vertical lifting device of Large-size rebar in a kind of high pier construction, two section steel fixtures be arranged in parallel, multiple jaw groove forming interference fit with reinforcing bar is provided with on the edge of a wing contacted, left pin-and-hole plate and right pin-and-hole plate is respectively equipped with at the two ends of two section steel fixtures, two section steel fixtures link together through left pin-and-hole plate and right pin-and-hole plate by clevis bolt
Section steel fixture two ends are provided with hanger.
Described section steel fixture adopts I-beam section, and the edge of a wing of I-beam section is oppositely arranged.
Described jaw groove respectively has a semicircle on two section steel fixtures, snaps together formation complete circle.
Described jaw groove is provided with anti-slop serrations.
Described left pin-and-hole plate and right pin-and-hole plate are fixedly arranged on different section steel fixtures respectively, and left pin-and-hole plate and/or right pin-and-hole plate are multi-disc.
Described multiple jaw grooves are uniform along section steel fixture.
The overall vertical lifting device of Large-size rebar in a kind of high pier construction provided by the invention, by the section steel fixture with multiple jaw groove arranged, can a vertical lifting many reinforcing bars, guarantee steel reinforcement abutting joints quality, reduce construction risk and cost.The present invention can ensure quick, the safety of the lifting of Large-size rebar, greatly improves the efficiency of high pier construction reinforcement installation.

Detailed description of the invention
As in Fig. 1 ~ 3, the overall vertical lifting device of Large-size rebar in a kind of high pier construction, two section steel fixtures be arranged in parallel 1, multiple jaw groove 2 forming interference fit with reinforcing bar 8 is provided with on the edge of a wing contacted, left pin-and-hole plate 3 and right pin-and-hole plate 4 is respectively equipped with at the two ends of two section steel fixtures 1, two section steel fixtures 1 link together through left pin-and-hole plate 3 and right pin-and-hole plate 4 by clevis bolt 5
Section steel fixture 1 two ends are provided with hanger 6.The hanger 6 arranged lifts by crane for connecting steel wire ropes 7.
Preferably, as in Fig. 3, described section steel fixture 1 adopts I-beam section, and the edge of a wing of I-beam section is oppositely arranged.Channel-section steel is adopted also to be feasible.
Optimize, as in Fig. 2, described jaw groove 2 respectively has a semicircle on two section steel fixtures 1, snaps together formation complete circle.Structure thus, is convenient to clamp reinforcing bar 8.
Preferably, described jaw groove 2 is provided with anti-slop serrations.Structure thus, for increasing friction force.
The structure optimized is as in Fig. 3, and described left pin-and-hole plate 3 and right pin-and-hole plate 4 are fixedly arranged on different section steel fixtures 1 respectively, and left pin-and-hole plate 3 and/or right pin-and-hole plate 4 are multi-disc.Structure thus, the section steel fixture 1 being convenient to two to be arranged in parallel is linked together by clevis bolt 5, and is convenient to clamping.
The structure optimized is as in Fig. 2, and described multiple jaw grooves 2 are uniform along section steel fixture 1.Structure thus, is beneficial to and keeps balance when lifting.
As in Fig. 1 ~ 3, in a kind of high pier construction, the method for the overall vertical lifting of Large-size rebar comprises the following steps:
One, the section steel fixture 1 with jaw groove 2 is made: get two i shaped steels, this routine shaped steel is work 10 shaped steel, the jaw groove 2 of the fixing reinforcing bar 8 of reinforcing bar 8 spacing processing is pressed in upper and lower flange plate position, the size of jaw groove 2 and the radius of reinforcing bar 8 smaller, and jaw groove 2 requires that the section steel fixture center line left and right at two is equal.Arrange left pin-and-hole plate 3 at section steel fixture two ends, another root two ends arrange right pin-and-hole plate 4.Respectively arrange one with the hanger 6 of section steel fixture seam symmetry at two section steel fixture 1 diagonal positions, hanger 6, as Heave Here, is connected with steel rope 7.With center line symmetry and arranging of hanger 6, jaw groove 2 requires that the requirement for section steel fixture 1 seam symmetry is the center-of-gravity position heart position wherein in order to section steel fixture 1 during satisfied lifting, ensure vertical lifting.Jaw groove 2 quantity arranges 8 ~ 12 usually.
Two, the left pin-and-hole plate 3 of two section steel fixture 1 one end and right pin-and-hole plate 4 run through by clevis bolt 5 be fixedly connected with, make section steel fixture 1 one-tenth hinge structure.
