Problems solved by technology

However, since the Y-shaped cast steel column weighs tens of tons and has a long size, it brings great difficulties to hoisting operations, especially long-distance hoisting operations.
[0004] In view of the above-mentioned related technologies, the inventor believes that when using Y-shaped cast steel columns as the main body of the support structure of the subway station, there is a defect that the hoisting operation is difficult

Embodiment Construction

[0044] The following is attached Figure 1-5 The application is described in further detail.

[0045] How to obtain a larger subway station space has become the main research direction of subway designers. Using Y-shaped cast steel columns with large load-bearing loads as the supporting body is one of the feasible construction schemes that can provide a larger subway station space. Due to the large size and dead weight of the Y-shaped cast steel column, it is very difficult to carry out the lifting operation. In order to reduce the difficulty of hoisting the Y-shaped cast steel column and improve the construction efficiency, an embodiment of the present application proposes a Y-shaped cast steel column and a hoisting method thereof.

[0046]The embodiment of the present application discloses a Y-shaped cast steel column. refer to figure 1 and figure 2 , The Y-shaped cast steel column includes a tee pipe 1 , a first branch 2 , a second branch 3 and a tension beam 4 . Whe...

Abstract

The invention relates to a Y-shaped cast steel column and a hoisting method thereof, and belongs to the technical field of cast steel columns and hoisting methods thereof. The Y-shaped cast steel column comprises a three-way pipe arranged on a steel pipe pile, a first branch connected with the three-way pipe, a second branch connected with the three-way pipe and a straining beam; one end of the straining beam is connected with one end, far away from the three-way pipe, of the first branch, and the other end of the straining beam is connected with one end, far away from the three-way pipe, of the second branch. The Y-shaped cast steel column has the advantage of being convenient to hoist.

Description

technical field [0001] The present application relates to the technical field of a cast steel column and its hoisting method, in particular to a Y-shaped cast steel column and its hoisting method. Background technique [0002] With the rapid development of domestic urbanization, the subway, as a green and convenient mode of transportation, has gradually become the main mode of travel in most cities. Crowded people and difficult transfers often occur in subway stations. How to obtain more station space has become an important research direction for subway designers. It is a common solution to use large steel castings as the main body of the supporting structure in subway construction projects. [0003] As a kind of large steel castings, Y-shaped cast steel columns can provide greater supporting force and can meet the construction requirements of providing a larger subway station space. However, since the Y-shaped cast steel column weighs tens of tons and has a long size, it...
