Abstract
The invention relates to a combined column with a cross-shaped section in civil engineering. The combined column is composed of a steel skeleton, a steel tube, a steel reinforcement framework and concrete and is characterized in that the steel skeleton is formed by welding steel plates; the combined column with the cross-shaped section is enclosed by using a stirrup; the steel skeleton is located on limbs of the cross-shaped column; the steel tube is located in the core of the cross-shaped column; and the combined column with the cross-shaped section, which is enclosed by using the stirrup, and the steel tube are filled with the concrete. The steel skeleton is welded to be T-shaped. Corners of the combined column with the cross-shaped section, which is enclosed by using the stirrup, are filled with longitudinal reinforcements. The concrete is gangue concrete containing broken gangue serving as an aggregate. Due to the adoption of the gangue concrete, the self-weight of the column is reduced, the resources are saved, and the environment is protected; and the steel reinforcement framework plays a role in constraining concrete and is capable of improving the bearing capacity of the column. The combined column with the cross-shaped section is used as a main structural member of a frame structure in a high-rise building or a long-span building, and has the characteristics of high bearing capacity, high rigidity, light weight, good plasticity and toughness, good impact and fatigue resistance, favorable earthquake resistance, energy saving, environment friendliness and the like.
Description
Technical field
Having the present invention relates to a kind of concrete component, particularly related to a kind of for the concrete cross section column in civil engineering, is a kind of novel star section coupled column.
Background technology
Current social, along with the lifting of expanding economy and Living consumption, the requirement of people to house is more and more higher, especially more and more payes attention to building structure and room layout.Sectional dimension due to common concrete column is often greater than the thickness of body of wall, have impact on the use of the interior space, is difficult to meet building requirement attractive in appearance.In order to address this problem, there is the form of structure of R. C. Cross Shape Column.The advantage of R. C. Cross Shape Column structural system is more outstanding, and scholar both domestic and external, expert are to this has been extensive, deep research.The theoretical system of R. C. Cross Shape Column basically forms, and the provinces and cities such as such as Tianjin, Shenyang, Guangdong, Shanxi have completed writing of local code, and and guide in engineering practice, building area reaches tens million of square metres.
But along with the development of Super High and long span building structure, the shortcoming of pure R. C. Cross Shape Column is more and more outstanding.As being subject to the restriction of ratio of axial compressive force to axial compressive ultimate capacity of section, if still adopt ordinary reinforced concrete cross section column under larger load, the sectional dimension of post will be caused very large; The limb length of cross section column cannot be oversize, easily can produce shear lag phenomenon after post limb is long, and therefore usual length by the limb of cross section column is extended the deadline in certain proportion with limb; Cross section column there occurs change due to section form, causes its mechanical characteristic also to there occurs change, and compared with ordinary rectangular post, supporting capacity and ductility decline all to some extent, and anti-seismic performance is unsatisfactory.
Meanwhile, gangue comprehensive utilization is the importance of comprehensive utilization of resources, and being the inevitable choice of China's energy resource structure, is also one of important measures of the Implement of sustainable development strategy." 12 " period " Central Committee of the Communist Party of China is about the suggestion of formulating national economy and social development the 12 five-year plan " points out: adhere to using building a resource-conserving and environment-friendly society as the important origin of force of accelerating transformation of the mode of economic development.Deeply implement and economize on resources and protection of the environment fundamental state policy, energy conservation, reduce greenhouse gas emission intensity, develop a circular economy, promote low-carbon technology, respond actively climate change.And the main aspect of the comprehensive utilization of gangue produces constructional materials exactly, comprise and produce lightweight aggregate, building product etc.
Therefore, herein under above-mentioned background, propose a kind of novel steel frame-steel pipe coal gangue concrete star section coupled column, this kind of coupled column combines the advantage of R. C. Cross Shape Column, steel core concrete column, combined steel and concrete column, coal gangue concrete post, alleviate resource pressure and environmental pressure, widen the application and development space of concrete cross section column greatly, there is very important Research Significance.
Summary of the invention
The object of this invention is to provide a kind of steel frame-steel pipe coal gangue concrete star section coupled column; this Novel combined column not only improves the stress performance of ordinary reinforced concrete cross section column; and take full advantage of gangue; accomplish effective utilization of discarded object; save resource, protect environment.The present invention is achieved through the following technical solutions: the T steel bone of steel frame-steel pipe coal gangue concrete star section coupled column is formed by Plate Welding, be positioned on the limb of cross section column, steel pipe is positioned at the center of post, first reinforcing bar and steel pipe are connected and fixed by welding or bolt when test specimen makes, then assembling reinforcement skeleton, formwork, builds coal gangue concrete.It is characterized in that: the reinforcing bar be positioned on cross section column limb improves limb portion stress performance; The steel pipe being positioned at core place improves supporting capacity and the ductility of cross section column; Containing the gangue fragment serving as aggregate in concrete, alleviate the deadweight of pillar; Due to the existence of peripheral coal gangue concrete, improve the fire resistance of coupled column.
Serve as the gangue fragment of aggregate in concrete, particle diameter at the gangue fragment of 5mm ~ 30mm, as the coarse aggregate in coal gangue concrete.According to every cubic metre of coal gangue concrete volume, coarse aggregate gangue weight 200kg ~ 1400kg, cement 400 kg ~ 600 kg, water 150 kg ~ 300 kg, the ratio of fine sand 150kg ~ 1500kg fully stirs.Gangue is too much not all right, can affect the intensity of coal gangue concrete, very few also not all right.
Advantage of the present invention and effect are:
1. make full use of discarded gangue, accomplish to turn waste into wealth, energy conservation, environmental protection;
2. steel pipe is positioned at the inside of direction concrete crossover sites in length and breadth, is subject to the protection of outer concrete, has good fire-resistant, decay resistance;
3. steel pipe inner concrete is in three-phase pressured state, improve the ultimate bearing capacity of pillar, is the application exhaust space of high-strength concrete;
4. reinforcing bar is positioned at the limb portion of cross section column, improves the stress performance in limb portion;
Containing the gangue fragment serving as aggregate in 5 concrete, alleviate the deadweight of pillar;
6. can first construct reinforcing bar, steel pipe, reinforcing bar, steel pipe are connected and fixed at bottom welding or bolt, then muscle and stirrup are indulged in colligation, pour into a mould coal gangue concrete after forming skeleton, thus form superposed column;
7., because the existence of reinforcing bar, steel pipe improves the ductility of post, improve the ultimate bearing capacity of post, be conducive to earthquake zone seismic design;
8. widen the application and development space of concrete cross section column, beautify architectural appearance.
