Problems solved by technology
[0002] For the rapid positioning construction of bridge steel pipes, due to the displacement when the foundation concrete is vibrated, it is difficult to fix the tall steel pipes accurately, which is greatly affected by the external environment, the installation and positioning are complicated, and the construction technology is relatively high.
When installing the steel pipe in the traditional method, the bottom is leveled by the pad iron, which has the problems of long time consumption, low precision and high cost of the pad iron leveling
At present, the bridge steel pipe positioning construction device on the market has a single function, the bridge steel pipe is fixed unstable, easy to shake, and needs to be adjusted repeatedly, which seriously affects the installation efficiency and accuracy; the length of the supporting part of the bridge steel pipe positioning construction device cannot be adjusted according to the change of the installation distance. Adjustment; the existing positioning construction device cannot be fixed with the existing positioning object, which is inconvenient for the positioning of bridge steel pipes and affects the installation accuracy

The invention discloses a bridge steel pipe positioning device, and belongs to the technical field of bridge construction devices. The positioning device comprises a U-shaped limiting rod, a supporting seat, springs, a supporting plate, limiting assemblies, fastening assemblies and supporting assemblies; a pair of waist rods of the limiting rod is provided with the pair of limiting assemblies; theupper ends of the pair of waist rods of the limiting rod are symmetrically provided with a pair of fixing assemblies; the middle of a bottom rod of the limiting rod is connected with the supporting seat in a sleeved mode; the multiple springs are uniformly fixed to the top surface of the supporting seat; and the supporting plate is fixed to the upper ends of the springs; and the pair of supporting assemblies are symmetrically fixed to the lower portion of the bottom rod of the limiting rod. The bridge steel pipe positioning device is simple in structure, easy and convenient to operate, accurate in positioning and high in working efficiency.
Description
technical field [0001] The invention relates to the technical field of bridge construction devices, in particular to a bridge steel pipe positioning device. Background technique [0002] For the rapid positioning construction of bridge steel pipes, due to the displacement during the vibration of the foundation concrete, it is difficult to accurately fix the tall steel pipes, which is greatly affected by the external environment, the installation and positioning are complicated, and the construction technology requirements are high. When installing steel pipes in the traditional method, the bottom is leveled by pad irons, which has the problems of time-consuming leveling with pad irons, low precision, and high cost. At present, the bridge steel pipe positioning construction device on the market has a single function, the bridge steel pipe is fixed unstable, easy to shake, and needs to be adjusted repeatedly, which seriously affects the installation efficiency and accuracy; th...
