Problems solved by technology

[0004] Aiming at the problem that the sudden change of stress between the column and the upper structure in the prior art is not conducive to the stability of the structure, the present invention provides a column with variable cross-section. There is a transition section in between, which has the characteristics of smooth surface and beautiful structure, and can conduct stress well, so as to realize the smooth transition of stress and the stable structure

Embodiment Construction

[0034] A column with a variable cross-section and its construction method provided by the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer with reference to the following description and claims. It should be noted that all the drawings are in a very simplified form and use imprecise scales, and are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.

[0035] see figure 1 , figure 1 It is a structural schematic diagram of a column with variable cross-section 100 , and the column with variable cross-section 100 is as follows from bottom to top: a cylinder section 110 , a transition section 120 , and a cuboid section 130 .

[0036] see figure 2 , figure 2 is a structural schematic diagram of the transition section 120 . The transition section 120 includes a bo...

Abstract

The invention discloses a variable section upright and a construction method thereof, which belongs to the field of building construction. The variable section upright comprises a cylinder section, a transitional section and a cuboid section in sequence from bottom to top, wherein the transitional section is enclosed by a bottom surface, a top surface, a double curved surface and a curved surface. As the end of a cuboid structure with large section area can have large contact area with an upper structure, the variable section upright provided by the invention is stably structured and convenient to construct; meanwhile, the transitional section with gradually varied section area is also arranged, the invention is advantaged in that stress is smoothly conducted, factors adverse to structural stability, such as stress mutation and the like, are eliminated, the external surface of the variable section upright is smooth and the structure of the variable section upright is beautiful.

Description

technical field [0001] The invention relates to a column with variable cross-section and a construction method thereof, belonging to the field of building construction. Background technique [0002] With the rapid development of cities, buildings are becoming denser and traffic is more congested, so many large cities vigorously develop viaducts. The viaduct includes the bridge deck, bridge piers, caps and underground infrastructure. Among them, the piers are often slender columns with a cross-section of rectangle, circle, ellipse or polygon with edges and corners. Surface connection or bridge deck connection through cover beams. [0003] At present, there are the following problems in the connection between the column and the bridge deck: when the column is directly connected to the bridge deck, the contact area is small, and there are problems of sudden changes in section and stress, which are not conducive to the stability of the structure; when the column is connected to...
