Abstract
The invention discloses a concrete column and a production method thereof. Webs are arranged in grids at four corners of hoops, the length direction of each web is in the longitudinal direction, the width direction of each web is on a diagonal line of a third main steel bar of the corresponding grid, the webs are fixed on the main steel bars through flange steel plates, and the webs are not in contact with the main steel bars. The production method includes the following steps: (1) fixing the main steel bars and the peripheral hoops of a frame; (2) welding the flange steel plates; (3) welding the webs; (4) welding the internal hoops on the main steel bars; (5) pouring concrete. The webs are arranged in the corner regions, advantageous effect of improving oblique strength of the concrete column is achieved on the premise that design strength in the two spindle directions of the concrete column is basically unchanged, and the 'strong column and weak beam' destructive mechanism is realized favorably. The concrete column is simple in structure, low in construction difficulty, high in cost performance and suitable for being widely porpularized in engineering.
Description
The application is number of patent application: 2013105332884, the applying date: 2013-11-04, title: a kind of concrete column
And preparation method thereof divisional application.
Technical field
The present invention relates to a kind of concrete column and preparation method thereof.
Background technology
The framework of steel reinforcement of existing concrete column includes that longitudinal main muscle and multilamellar are fixed on stirrup horizontal on main muscle, often
Layer stirrup is the outside framework having the square space of multiple rows of multiple row for rectangle inside, three exterior angles in the space on four angles of stirrup
Place is respectively equipped with a main muscle.
China is many earthquakes country, and the city of more than 80% is positioned at earthquake territory, and the earthquake that earthquake causes is increasingly severe, especially
Its destruction of large amount of building in Wenchuan earthquake is collapsed, and causes huge casualties and economic loss, reduces structure and breaks
The bad casualties brought and economic loss are the responsibilities and obligations of Structural Engineering technical staff's origin.In seismic design of structures,
" strong column and weak beam " type failure mechanism is one of our most basic design principle of following, but a large amount of reinforcing bars mix in Wenchuan earthquake
Solidifying soil frame house destroys and even collapses, and occurs in that substantial amounts of " the weak post of brutal " type failure mechanism, does not form design specification
Requiring our desired " strong column and weak beam " type failure mechanism i.e., design is lack of standardization, construction except part building exists for this phenomenon
Outside the reason such as bad, important reason is concrete column in oblique intensity less than two major axes orientation intensity (oblique is
Refer to the diagonal of stirrup, two major axes orientations refer to stirrup two in the direction of separated time), and due to ground motion tool during earthquake
There is the uncertainty in multi-dimensional nature, randomness and direction, cause concrete column under oblique geological process to destroy.
Summary of the invention
The technical problem to be solved in the present invention is: provides the concrete column that a kind of shock resistance is good, and provides a kind of aforementioned
The manufacture method of concrete column.
In order to solve above-mentioned technical problem, concrete column of the present invention includes concrete column and is embedded in concrete column
Framework of steel reinforcement, framework of steel reinforcement includes that longitudinal main muscle and multilamellar are fixed on stirrup horizontal on main muscle, and every layer of stirrup is outside
There is the framework in the square space of multiple rows of multiple row for rectangle inside, at three exterior angles in the space on four angles of stirrup, be respectively equipped with master
Muscle I, main muscle II and main muscle III, main muscle I, main muscle II and main muscle III be described main muscle, and main muscle III is positioned at the top of stirrup framework
At angle, in the space on four angles of described stirrup, be equipped with web, the length direction of web in a longitudinal direction, web
Width on the diagonal at main muscle III place in corresponding space, web by edge of a wing Interal fixation on main muscle, web with
Main muscle does not contacts.
Described edge of a wing steel plate is multi-turn cincture and banding steel plate outside all of main muscle I and main muscle II, edge of a wing steel plate
Being staggered in a longitudinal direction with stirrup, edge of a wing steel plate is welded to connect with all main muscle I and main muscle II, the web in each space
Being positioned at the edge of a wing steel plate side away from corresponding main muscle III, the side of web is connected with edge of a wing Plate Welding.Owing to edge of a wing steel plate is
Ring-type, bigger to the restraining forces of concrete so that concrete column overall construction intensity is high.
In order to the oblique intensity making monolithic concrete post is the strongest, described web runs through the whole height of framework of steel reinforcement,
The whole height of web is evenly arranged with many group edges of a wing steel plate.
In order to obtain optimal cost performance, described web is arranged in the two ends of framework of steel reinforcement, and the layout height often held is
The Breadth Maximum of the cross section of 1-2 times of concrete column, is evenly arranged with many group edges of a wing steel plate on the whole height of web.
The manufacture method of concrete column of the present invention, comprises the steps: (1) fixing main muscle and framework periphery stirrup；(2) exist
Welded flange steel plate in the main body of framework of steel reinforcement；(3) on the steel plate of the edge of a wing, web is welded；(4) the internal stirrup of welding on main muscle；
(5) cast concrete.
The invention has the beneficial effects as follows:
(1) present invention is by arranging web at folding corner region, and not changing, the design of concrete column two major axes orientation is strong
On the premise of degree, play the advantageous effect improving the oblique intensity of concrete column, be conducive to the realization of " strong column and weak beam " failure mechanism.
(2) when earthquake occurs, due to the existence of web intensive aspect, improve the cross section ductility of concrete column, Jin Erke
To improve structure deformability under geological process.
(3) simple structure of the present invention, difficulty of construction is little, have the highest superiority of effectiveness, be suitable for extensively pushing away in engineering
Extensively.
