Abstract
The invention relates to a reinforced concrete hollow column. According to the invention, the section of the column body of the reinforced concrete hollow column is in arbitrarily shape and has holes which are in arbitrarily shapes. The neutral axis area of the column body of a large-size reinforced concrete column is hollowed to form the holes which are in arbitrarily shapes and used for improving the stress performance and rigidity of the reinforced concrete column and reducing the dead weight of the reinforced concrete column so as to achieve the purposes of saving materials such as rebar, concrete, stone, sand and water as well as labor, and saving energy consumption and money. Due to reduction of use amount of the concrete, the pouring time of the concrete is correspondingly reduced, and thus noise generated when the concrete is vibrated is reduced, concrete high altitude transportation cost is reduced, and the like.
Description
Technical field
The invention belongs to reinforced concrete works technical field, particularly a kind of reinforced concrete hollow column and construction method thereof, this hollow column uses in highrise building middle frame or frame-shear wall, tubular construction.
Background technology
At present in various higher, large public building, housing construction, all have the reinforced concrete post of larger volume, in this Structural Engineering, be generally all designed to solid concrete rod structure.First press its section of empirical assumption during design, calculate the moment M under lotus effect outside, shear V, torque T, axle power N by solid section, determine strength grade of concrete, calculate its arrangement of reinforcement by M, V, T, N of this section, be depicted as working drawing; First by reinforcing bar in design drawing requirement colligation post during construction, after in supervising engineer's acceptance(check), also label are recognized; The column template completed is installed again, after also label are recognized in supervising engineer's acceptance(check); Again by design drawing requirement concreting, and need the other station of supervising engineer; After concreting completes, by relevant specification requirement, maintenance is carried out to reinforced concrete post; Folding except column template, then checks and accepts its profile, size etc., and is namely finished product after by supervising engineer's passed examination, also examination recognized by label, available, or carries out next process.
Summary of the invention
The object of the present invention is to provide a kind of reinforced concrete hollow column, this hollow column overcomes in existing higher, large public building, housing construction, the defect that the consumptive material existed the steel concrete column technology of larger volume is more.
Another object of the present invention is to provide the construction method of above-mentioned reinforced concrete hollow column.
As above conceive, technical scheme of the present invention is: a kind of reinforced concrete hollow column, comprises reinforced concrete post cylinder, it is characterized in that: the section of reinforced concrete post cylinder is arbitrary shape, has the hole of arbitrary shape in section.
The section of above-mentioned reinforced concrete post cylinder is circular.
The section of above-mentioned reinforced concrete post cylinder is square.
The section of above-mentioned reinforced concrete post cylinder is polygon.
The position of above described holes is at the neutral axis place in natural axis district.
Above described holes is one or more.
The construction method of above-mentioned reinforced concrete hollow column, carry out according to the following step:
1. first think that this post belongs to the steel concrete rod structure of larger volume by designer;
2. according to cross dimensions and the shape of outer lotus situation and floor overall height and certain special layers floor height setting reinforced concrete post, and position and the quantity of section mesopore is set;
3. by the moment M, shear V, torque T, axle power N etc. that calculate post under suffered outer lotus effect, and determine strength grade of concrete and by M, V, T, N, arrangement of reinforcement calculating is carried out to section, be depicted as working drawing;
4. unit in charge of construction is by design drawing requirement at the good reinforcing bar of post position colligation, installs the inside and outside template of concrete column after acceptance(check) again, concreting again after acceptance(check);
5. curing concrete, removes all templates, takes out the filler in pore-forming material and hole, can be delivered for use or carry out next process after acceptance(check).
The section of above-mentioned reinforced concrete post can be one-time-concreting concrete formation, also concreting several times can be divided shaping according to the length of post.
The natural axis district of larger volume concrete column cylinder is hollowed out the hole forming arbitrary shape by the present invention, in order to improve reinforced concrete post stress performance and rigidity, alleviate its deadweight, thus reach save reinforcing bar, cement, stone, sand, water, etc. material and artificial, economize energy consumption, save money.Because concrete amount reduces, the time also corresponding minimizing of concreting, thus the noise produced when decreasing vibrated concrete, and decrease the expense etc. to high-altitude transport concrete.
Accompanying drawing illustrates:
Fig. 1 is the section of reinforced concrete post cylinder is square schematic diagram;
Fig. 2 is the section of reinforced concrete post cylinder is criss-cross schematic diagram;
Fig. 3 is the section of reinforced concrete post cylinder is oval schematic diagram;
Fig. 4 is the section of reinforced concrete post cylinder is columniform schematic diagram;
Fig. 5 is the section of reinforced concrete post cylinder is polygonal schematic diagram.
Detailed description of the invention:
As shown in the figure: a kind of reinforced concrete hollow column, in tall and big public building, housing construction, the reinforced concrete post of larger volume carries out hollowing out design.It is characterized in that at the section of reinforced concrete post cylinder 1 be arbitrary shape, can be square, cross, ellipse, cylindrical and polygon, and in the natural axis district of section, have the circular port 2 of arbitrary shape.The position of above described holes can, at neutral axis place, can be one or more.
Specific construction process of the present invention is:
1, first think that this post belongs to the steel concrete rod structure of larger volume by designer.
2, cross dimensions and the shape of reinforced concrete post is set according to outer lotus situation and floor overall height and certain special layers floor height etc., the section of concrete column can be square, circular, polygonal and criss-cross etc., and sets the position of section mesopore and quantity etc.Section can be one-time-concreting concrete formation, also concreting several times can be divided shaping according to the length of post.
3, by the moment M, shear V, torque T, axle power N etc. that calculate post under suffered outer lotus effect, and determine strength grade of concrete and by M, V, T, N, arrangement of reinforcement calculating is carried out to section, be depicted as working drawing.
4, unit in charge of construction is by design drawing requirement at the good reinforcing bar of post position colligation, installs interior (pore-forming material and filler), the exterior sheathing of concrete column after acceptance(check) again, concreting (need supervising engineer other station) again after acceptance(check).
5, curing concrete, removes all templates, takes out the filler in pore-forming material and hole, can be delivered for use or carry out next process after acceptance(check).
The material of described pore-forming need be fixed on reinforcing bar or pore-forming material and filler have certain own wt, in casting and compacting of concrete process, can not be floated because concrete liquefaction produces larger buoyancy, thus off-design position (hollow hole position deviation must meet relevant specification regulation).
The hole wall of described reinforced concrete post mesopore need be smooth, and under the weight effect of filler, its distortion should in specification allowed band.
Filler in the material of described pore-forming and hole can repeatedly use with cost-saving.
