Abstract
The invention discloses a section-variable crossed circular tube switching steel column. The section-variable crossed circular tube switching steel column comprises an upper circular tube column, a middle conical column, a lower circular crossed column and a steel bracket, wherein the top end of the conical column is welded to the upper circular tube column and the bottom end of the conical column is welded to the circular crossed column; and the steel bracket is welded to the outer surface of the upper circular tube column. The invention also discloses a manufacturing method for the section-variable crossed circular tube switching steel column. By the invention, switching of steel column structural styles on underground and aboveground parts of high buildings is realized; a large quantity of steel materials are saved for the steel structures on the underground parts; and aims of minimizing the section and maximizing the bearing capacity are fulfilled.
Description
Technical field
The invention belongs to a kind of combination steel column and preparation method thereof, be specially a kind of coupled column that combines by cross steel column, tubular pillar and tapered pole and preparation method thereof.
Background technology
High speed development along with China's economic; Highrise building in all parts of the country is rised sheer from level ground like the mushrooms after rain; Because building is increasingly high; The scale of construction is increasing, considers that from each side such as structural strength, security performances its form of structure also turns to steel reinforced concrete structure or steel work by reinforced concrete structure.Reinforced concrete post in the highrise building can not satisfy the requirement of highrise building, is replaced by the concrete steel column.In the highrise building, under ground portion is stressed less relatively, as the steel column cross section is designed to the uniform section form from bottom to up; Then which kind of structure waste material owing to the worsening shortages of present steel, adopts to reach and reduces the steel consumption; The cross section minimizes, the maximized purpose of bearing capacity.
And continuous variation along with the architectural design moulding; In the highrise building; The steel work shape of overground part demonstrates various moulding, no longer is single box structure, has occurred cylindrical; And if, just wasted steel using amount greatly at the steel column of under ground portion employing with the same cross section of overground part.
Summary of the invention
Goal of the invention: in order to solve the problems of the prior art; The invention provides and a kind ofly can reduce steel using amount; Can minimum variable cross-section cross pipe conversion steel column be accomplished in building under ground portion cross section, also disclosed the preparation method of this variable cross-section cross pipe conversion steel column simultaneously.
Technical scheme: to achieve these goals, a kind of variable cross-section cross pipe conversion steel column of the present invention comprises: top tubular pillar, middle part circular cone post, the circular cross post in bottom and steel corbel; The top of said circular cone post and top tubular pillar are assembled and welded together, and its bottom and circular cross post are assembled and welded together; Said steel corbel dress is welded in the external surface of top tubular pillar.
Said top tubular pillar is divided into epimere, stage casing and hypomere; Said hypomere is consistent with the structure of epimere; The external diameter of said epimere, stage casing and hypomere is identical; Said epimere comprises: four-bladed vane, outer circle steel pipe and stiffener; Said outer circle steel pipe is offered four notches; Said four-bladed vane is welded into vertical cross by three plane steel plate dresses, and the width of four-bladed vane cross section is identical with outer circle steel pipe external diameter, and the axial length of four-bladed vane equals the length of notch on the outer circle steel pipe, and the thickness of four-bladed vane is consistent with the width of notch; The vertical dress of stiffener is welded on the four-bladed vane, and welds with the outer circle steel pipe is inboard; Four axial checkposts of four-bladed vane are gone in the notch and welding is fixed; Stiffener and four-bladed vane externally round steel pipe inside have played the effect of supporting, and make the weight capacity of epimere stronger.
The post of circular cone described in the present invention is a truncated cone; Said circular its external overall of cross post is cylindrical.The top tubular pillar is the overground part of building, and the circular cross post of bottom is the under ground portion of building, makes the under ground portion of building and the cross sectional area of overground part consistent according to conventional way; But under ground portion is stressed less relatively; Adopt this mode rolled steel dosage of lower part greatly lavishly, under ground portion and the overground part transition smoothly of adopting the circular cone post just to build among the present invention had both reduced the steel consumption; Reached the cross section and minimized, made the bearing capacity maximization again.
The invention also discloses a kind of preparation method of variable cross-section cross pipe conversion steel column, the concrete steps of this method are following:
(A) variable cross-section cross pipe conversion steel column is divided the making segmentation in computer; With the top tubular pillar as an independent segmentation; Circular cone post and circular cross post are merged into a segmentation; The segmentation that is merged into by circular cone post and circular cross post is called: special-shaped circular cross post; With steel corbel as an independent part;
(B) top tubular pillar, special-shaped circular cross post are deepened setting-out in computer; Said top tubular pillar is decomposed into: epimere, stage casing and hypomere; And being decomposed into: four-bladed vane, outer circle steel pipe and stiffener with epimere and hypomere; Said stage casing is decomposed into: the round steel pipe of a hollow;
The circular cross post of said abnormity is decomposed into: special-shaped H shape steel, special-shaped T row's steel and internal partition; The panel of said special-shaped H shape steel and special-shaped T row steel is a curved panel, and the lower height of this curved panel is consistent with width, and top is one acclivitous fan-shaped;
(C) steel plate is processed into the plate unit that requires size; Then each plate unit dress seam is held together, constitute the special-shaped H shape steel of top tubular pillar, special-shaped T row's steel and internal partition; Four-bladed vane in the tubular pillar of top, outer circle steel pipe and stiffener, the stage casing that constitutes by round steel pipe; And I-shaped steel corbel;
(D) four-bladed vane, outer circle steel pipe and stiffener are adorned epimere and the hypomere that is welded into the top tubular pillar; Again epimere, stage casing and hypomere dress are welded into the top tubular pillar;
(E) special-shaped H shape steel and special-shaped T row steel are assembled and welded together, constitute the shell of special-shaped circular cross post, again the internal partition vertical welding is connected on special-shaped H shape steel and the special-shaped T row steel, constitute special-shaped circular cross post;
(F) circular cross post of abnormity and top tubular pillar are assembled and welded together;
(G) steel corbel is adorned the external surface that is welded in the top tubular pillar.
Beneficial effect: the present invention has following advantage:
1, the present invention has realized the underground transformation with overground part steel column form of structure of highrise building, has saved a large amount of steel for the under ground portion steel work, has reached the cross section and has minimized, the maximized purpose of bearing capacity.
2, middle and upper part tubular pillar of the present invention and circular cross post have been realized the perfect transition fusion through middle circular cone post, make the whole weight capacity of whole steel work strong.
3, in the preparation method according to the invention circular cone post and circular cross post are made as a making segmentation together, rather than circular cone post and circular cross post are made amalgamation more separately; Avoid the increase banjo fixing butt jointing, strengthened whole fastness degree and total quality.
