Description

Lattice column torsion adjusting and limiting device Technical Field The utility model relates to the technical field of concrete pile foundations, in particular to a lattice column torsion adjusting and limiting device. Background The lattice column is a building form with strong bending resistance, and is characterized in that the material area is arranged far away from the inertia axis, so that the bending resistance of the component can be enhanced under the same axial resistance condition, and the material is saved. In subway station construction, lattice column is many to cooperate drilling bored concrete pile to form and hold the stake and use. During construction, a bored pile is generally drilled, a bored pile reinforcement cage is lowered, then a lattice column is lowered, welded and fixed with the reinforcement cage, and finally concrete pouring is performed, wherein the direction of the lattice column needs to be strictly controlled during hoisting of the lattice column, otherwise, the direction of the lattice column is twisted after concrete pouring is completed, and the lattice column cannot be welded with a subsequent supporting system, so that the stress and safety of a foundation pit support structure are affected. The lattice column torsion occurrence frequency is high, the subsequent treatment and repair reinforcement are difficult, and therefore, the control of the lattice column installation direction is extremely important. The existing lattice column hoisting and placing technology is that steel bars are inserted into gaps of the lattice columns in the hoisting process, and workers adjust the lattice columns through the steel bars. The prior art has high risk, the lattice column is difficult to control to twist back and forth in the adjustment process, the direction is difficult to control, and after the lattice column is lowered to the design elevation, the lattice column is ensured to be stable by infinite position measures, so that the problem is not solved in the prior art. Disclosure of utility model The utility model aims to provide a lattice column torsion adjusting and limiting device, which is characterized in that a plurality of groups of adjusting components are arranged and clamped around a lattice column body, so that the direction of the lattice column body can be adjusted more conveniently and safely through a fixing rod, and the lattice column body and a steel casing can be limited and fixed through adjusting the position of the adjusting rod after the direction is adjusted, thereby avoiding the influence on the lattice column body caused by subsequent construction and torsion dislocation again, and solving the problems in the background art.
