Problems solved by technology
[0004] At present, most of the super high-rise structures with slanted columns have problems of super height and overweight. The erection of steel pipe support frames has the problem of large volume or failure to erect due to too dense structure. Therefore, it is necessary to find a new construction method for slanted column support frames.

Embodiment Construction
[0030] Example figure 1 and figure 2 As shown, the construction method of the tall non-orthogonal large-inclination angle special-shaped concrete slanted column of the present invention comprises the following steps:
[0031] Step 1. Determine the position of the slanting column 1 by setting out on the outer edge of the poured floor 4, and bind the slanting column reinforcement at this position, and place the bottom standard section 2 of the slanting column shaping steel mold surrounding the slanting column reinforcement, and the bottom standard section 2 Weld the I-beam joists 3 at intervals at the bottom, and the spacing is consistent with the outer corrugation spacing of the bottom standard section 2, and at the same time erect low-area scaffolding 5 from the ground on the outer edge of the floor 4 and the outside of the I-beam joists 3;
[0032] Step 2. Bind the steel bars of the slanted column, and install the standard section 6 of the bottom standard section 2 and the ...

The invention discloses a construction method of a tall and big non-orthogonal large-inclination-angle special-shaped concrete batter post. According to the construction method, construction of the batter post is achieved by utilizing a supporting system with an all-round scaffold and a bailey frame being combined and utilizing a tension brace system of a batter post shaped steel formwork, the all-round scaffold and the bailey frame are used for supporting of the batter post shaped steel formwork and serve as a construction operation platform, and the tension brace system of the batter post shaped steel formwork is composed of an I-shaped steel joist, a diagonal bar, a diagonal draw bar, a horizontal pull bar, the all-round scaffold and an anchoring piece; and the batter post shaped steelformwork comprises a made-to-order section, a standard section and a made-to-order wooden mould, and is fixed through the tension brace system, so that pouring of batter post concrete is achieved. According to the construction method, the defects that in batter post construction, erecting of a traditional steel pipe supporting frame is very dense, and the erecting height cannot exceed 30 m are overcome, by adopting the supporting system with the all-round scaffold and the bailey frame being combined, requirements for the support strength and rigidity in the construction process of the batter post are met, construction operation is facilitated, the construction quality of the batter post is improved, the construction period is shortened, and the cost is saved.
Description
technical field [0001] The invention relates to the technical field of construction engineering, in particular to a construction method for a tall, non-orthogonal, large-inclination-angle special-shaped inclined concrete column. Background technique [0002] With the rapid development of the construction industry, a variety of landmark buildings with novel shapes and unique structures have emerged. In order to meet the needs of large landmark buildings in terms of appearance, concrete slanted columns have been widely used. At present, there are no current national regulations on the construction of the inclined column, and there are no mature construction methods to refer to. The construction process mainly adopts the fastener-type steel pipe support frame, but the height of the fastener-type steel pipe support frame is affected by the weight of the frame and the load capacity of the steel pipe. Due to the influence of force, the erection height is greatly limited. [0003]...
