Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that the traditional single-layer operation platform cannot precisely adjust the verticality of the lattice column during the construction process of the subway lattice column. The present invention provides a vertical adjustment device for the construction of the lattice column. The layer operation platform can realize the precise adjustment of the verticality of the lattice column

Embodiment 1

[0038] This embodiment provides a vertical adjustment device for lattice column construction;

[0039] Such as figure 1 and figure 2 As shown, the vertical adjustment device for lattice column construction in this embodiment includes an upper platform 1 and a lower platform 2 stacked on each other and a plurality of screw rods 4 respectively arranged on the upper platform and the lower platform. The screw rods are located in the same plane and evenly distributed around the platform. The upper platform 1 and the center of the lower platform 2 are provided with a hanging hole 6 for placing the lattice column 8, and its size can add 20mm to the diameter of the steel cage 9, It is convenient for the steel cage 9 and the lattice column 8 to be lowered. If the length of the equilateral angle steel of the lattice column is greater than 20cm, the side length of the lowering hole should be the actual diameter of the reinforcement cage plus the length of the equilateral angle steel. ...

Embodiment 2

[0050] This embodiment provides a method for using a vertical adjustment device for lattice column construction;

[0051] Such as figure 1 and figure 2 As shown, the method for using the vertical adjustment device for lattice column construction in this embodiment includes the following steps:

[0052] a. Lift the upper platform 1 and the lower platform 2;

[0053] b. Adjust the levelness of the upper platform 1;

[0054] c. Surveyors measure and place the guard pile points to the top of the upper platform, and make corresponding marks;

[0055] d. Use a crane to lift, and lower the lattice column to the design elevation position and use I-beams for shelving;

[0056] e. Adjust the verticality of the lattice column.

[0057] In this embodiment, in step a, before the platform is placed, the placement position of the lower platform 2 should be processed in advance, and sleeper pads or prefabricated reinforced concrete slabs can be used to place it, and the reinforcement ca...

Abstract

The invention discloses a verticality adjusting device for latticed column construction and a using method. The verticality adjusting device comprises an upper platform, a lower platform and a plurality of screw rods, wherein the upper platform and the lower platform are overlapped, and the screw rods are arranged on the upper platform and the lower platform. The screw rods on each platform are located in the same plane and evenly distributed on the periphery of the platform. A hoisting hole used for placing a latticed column is formed in the center of each of the upper platform and the lower platform. A leveling mechanism used for adjusting the horizontal degree of the upper platform is further included. The screw rods on the upper platform are used for conducting plane positioning on latticed columns to prevent severe plane position deviation, and meanwhile, the screw rods on the lower platform are used for conducting verticality adjustment on the latticed columns; due to the double-layer platform structure of the verticality adjusting device, the verticality is controlled more directly compared with a traditional single-layer platform, the adjusting precision is higher, operation is more convenient, one-time construction quality of the latticed columns is ensured, waste caused by rework is avoided, construction efficiency can be improved, and the construction cost is lowered.

Description

technical field [0001] The invention relates to the construction field of underground engineering, in particular to a construction vertical adjustment device and a use method of lattice columns in subway construction. Background technique [0002] Lattice column is a steel column whose cross-section is generally shaped steel or steel plate designed with biaxial symmetry or uniaxial symmetry. It is widely used in the construction of subway deep foundation pits. It is mainly used as temporary support in the middle section of steel pipe support to support axial load and reduce The steel pipe supports the net span and other functions, and some lattice columns are considered to be constructed together with the main structural columns to support the load in the later stage. During construction, if the verticality of the lattice column deviates, the eccentricity of the compression will cause the instability of the lattice column, and the severe one will not meet the design requirem...
