Description
Technical Field
The utility model relates to a steel core concrete column field specifically is a thick aggregate sinks in order to reduce the maintenance stage, and rib steel core concrete column is arranged in the screw thread slope of installation rib in reinforced concrete column.
Background
With the development of building engineering and the acceleration of urban modernization process, in order to meet the development requirements of large-span bridges and high-rise buildings, the steel pipe concrete structure enters the field of vision of people, wherein the application of the steel pipe concrete column is the most extensive. The steel pipe concrete column effectively combines steel and concrete, and is favorable for improving the performance of the structure. In order to fully exert the advantages of two materials, the quality of concrete is required to be paid attention to, however, in the maintenance stage after the concrete pouring is finished, as the coarse aggregate is influenced by gravity, the coarse aggregate can be rapidly sunk compared with the fine aggregate, concrete mixtures can be gradually separated, the internal composition and the structure are gradually uneven, the problems of concrete segregation, poor compactness and the like can be caused when the coarse aggregate is seriously sunk, the problems of influencing the pumping construction performance of the concrete, damaging the apparent effect of a concrete structure, easily generating cracks and the like can be caused, the concrete strength is reduced, the bearing capacity of the concrete structure is seriously influenced, the safety performance of the structure is damaged, the impermeability and the frost resistance and the durability of the concrete are reduced, the quality of the concrete is seriously influenced, and the superior performance of the steel pipe concrete column is seriously influenced, and the expected effect cannot be achieved. Therefore, in order to achieve the important function of the steel pipe concrete column in the structure, a corresponding solution should be provided for the sinking of the coarse aggregate in the curing stage.
In the traditional technology, in order to ensure the quality, a remedy method of spreading a layer of aggregate between pouring layers is adopted, or in order to reduce the sinking, the method has to adopt smaller slump and shorter vibration time, so that the high-density concrete is difficult to convey, the fluctuation of the uniform distribution rate of the aggregate is larger, or measures such as increasing the proportion of fly ash in concrete mixing, improving the sand rate, increasing additives and the like are adopted to prevent the segregation phenomenon, and the methods can not simply and effectively solve the problems, so that the manufacturing cost is high, the construction requirement is high, and even the adverse effect is generated on the structure.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art, the utility model discloses the technical problem who plans to solve provides a rib steel core concrete column is arranged in screw thread slope. The utility model discloses a be the ascending intermittent type of screw thread and arrange the mode and consolidate great large size rib on the inner wall of the steel pipe that the steel core concrete column used, solved because the excessive sinking of the thick aggregate of maintenance stage can form the thick aggregate of lower part and gather after concrete placement accomplishes, lead to the production of concrete segregation phenomenon to influence the closely knit degree of concrete, cause the intensity of concrete to reduce, the steel core concrete column can not exert the problem of good performance.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the steel tube concrete column with the ribs arranged in the inclined mode through the threads comprises a steel tube with the ribs and concrete, the steel tube with the ribs comprises the steel tube and a plurality of ribs fixed on the steel tube, the ribs are fixed on the steel tube in a spiral rising mode, and the vertical distance between every two adjacent ribs is 0.15-0.3 m.
