Description
Technical field
The present invention relates to the construction technology of highrise building, particularly the technical field of construction of concreting in steel pipe column.
Background technology
The method of concreting mainly contains in the steel pipe column in the construction work: pumping, jacking pouring method, a high position leave without vibration method, segmentation pouring method and artificial manual paragraph by paragraph pouring method successively etc.Because the steel pipe column of highrise building is welded to each other by many steel pipes and forms, in order to add intensity through steel pipe column, usually in steel pipe column, be provided with the horizontal dividing plate of multiple tracks, and concrete is from topmost building downwards, so, more than the total defective of existing each method be: the concrete after the pouring, particularly the concrete compactness in bottom is poor, this exists high potential safety hazard for highrise building.
Summary of the invention
The present invention seeks to propose a kind of steel pipe column inner concrete conduit that can effectively improve the cement concrete compactness after the pouring and import the job practices of building.
After the present invention earlier erects steel pipe column, after concreting layer by layer from bottom to top, characteristics are: be fixed with the multiple tracks internal partition in the described steel pipe column respectively, the center of every dividing plate is offered and is used for interting the through hole of conduit; When building, insert conduit in steel pipe column, the port of export that makes conduit vibrates after finishing the building of steel pipe column between two adjacent internal partitions between two adjacent internal partitions, upwards promote conduit then, again the steel pipe column between last one group of two adjacent internal partition is built.
The present invention has made full use of the former internal partition that is used to reinforce steel pipe column, make every layer internal partition carry out weight supporting to the concrete on it, can realize that building of steel pipe column inner concrete is fully closely knit, control concrete compaction below the steel pipe column internal partition to the full extent well, concrete below the internal partition is not produced drowns oneself, detect by the intensity of ultrasonic wave to the steel pipe inner concrete, concrete compactness reaches code requirement, and the phenomenon of drowning oneself does not appear in tubing string internal partition below.Improved the pouring quality of steel pipe column inner concrete, increased the steel work bulk strength, reduced, and taked steel pipe column to scrap or the steel pipe column inner concrete is taked the measure of reinforcement aspect, saved fund because of tubing string inner concrete quality leakiness, insufficient strength.
In addition, the present invention sets out pore on each internal partition, and described venthole is positioned at the outside of through hole.Be convenient to increase concrete exhaust, airing function, in time discharge because of building the air that brings, the layer of concrete of just building is compactness more.
For the concrete compaction of controlling well below the steel pipe column internal partition, surface concrete is not produced drown oneself, internal partition of the present invention is funnel-form, and described through hole is positioned at the foot on internal partition plane, and the angle of internal partition sidewall and center line is 45～60 °.
Also when the steel pipe column between two adjacent internal partitions of each group was built, concreting 10cm place below the lastblock internal partition of this group gave over to and builds next time in the present invention,
Purpose is to allow concrete self shrink earlier, so just can prevent better that concrete from occurring drowning oneself below internal partition and produce the gap.The end that of conduit was positioned at the following 20cm of the concrete horizontal face place that built last time when built next time.Concrete will by conduit downwards around overflow, avoided concrete in injection process, a large amount of air to be contained in steel pipe column, the density of building with raising.
In addition, drown oneself in order to prevent that concrete from producing, the time interval of adjacent twice concreting is 30 minutes.
When vibrating, vibrating head is inserted into 10～20cm place below the layer of concrete of building previously, the concrete of two-step pouring can be combined well.
Concreting in steel pipe column when the capital, and vibrate finish after, the concrete of 30cm height above in the steel pipe column is removed, treat to build again after 30 minutes and vibrate.Because when the steel pipe capital was arrived in concreting, cement paste was upwards general, the ratio of coarse aggregate reduces, and in order to guarantee the intensity of steel pipe column inner concrete, the concrete of upper part in the steel pipe capital is removed, and builds again.
Earlier directly in steel pipe column, build the high concrete of 1.9～2.3m, then conduit is inserted in the concrete degree of depth and reach and carry out first time intubate more than the 20cm and build.By progressively promoting, make conduit can not expose the concrete face, prevent to produce bubble.
The specific embodiment
Case engineering: Xi'an research and development centre, underground two-layer, 24 layers on the ground (highly being 93.25 meters on the ground), 40338 square metres of building areas.This project is a frame construction, designs 576 of steel box columns altogether, and underground two layers is (two segmented columns), and the post height is 10.34 meters; More than three layers and three layers (three segmented columns), the standard column height is 11.4 meters on the ground, all adopts pouring concrete in the square shaped pipe post.
The interior sectional dimension of square shaped pipe post is 650mm * 650mm, 550mm*550mm, and concrete placing adopts C35, C40, C45, C50 concrete in the square shaped pipe post, about total irrigation amount 750m3.Be welded with 6 road rectangle internal partitions respectively by rib in each square shaped pipe post of this project, internal partition is of a size of 650mm*650mm, and central through hole is Φ 300mm, four jiaos of air-vents that four Φ 25mm are set.Internal partition is funnel-form, and central through hole is positioned at the foot on internal partition plane, and the angle of internal partition sidewall and center line is 45～60 °.
Conduit can adopt Ф 150 welded steel pipes, and its external diameter is convenient to increase concrete exhaust, airing function less than the central through hole diameter of internal partition.
The commodity in use concrete adds a certain amount of micro-expanding agent in concrete, make concreting after micro-expanding agent reach closely knit with compensate for shrinkage; Suitable reduction cement consumption increases the admixture materials.Mix suitable water reducing agent; Increase the proportion of fines, improve aggregate grading (sand should use in coarse grain directly, the rubble of stone employing 5～25mm); Suitably increase the consumption of Admixture (pumping admixture, water reducing agent).Match ratio is joined definite by test room's examination, and provides the concrete mix list.
Each concreting 10cm place below dividing plate gives over to and builds next time, and just in time to inject tubing string inner concrete 20cm dark for conduit when built next time.
Key points for operation:
Steel pipe column is erect firm after, in steel pipe column, inject the high concrete of 1.9～2.3m earlier, again conduit is inserted that the degree of depth reaches more than the 20cm in the concrete, then concreting layer by layer from bottom to top.
When building, in steel pipe column, insert conduit, the port of export that makes conduit is between two adjacent internal partitions, after finishing the building of steel pipe column between two adjacent internal partitions, vibrate, upwards promote conduit then, but can not expose the concreting surface layer,, again the steel pipe column between last one group of two adjacent internal partition be built in order to avoid outside air enters in the concrete.
When the steel pipe column between two adjacent internal partitions of each group is built, concreting 10cm place below the lastblock internal partition of this group gives over to and builds next time, and the end that of conduit was positioned at the following 20cm of the concrete horizontal face place that built last time when built next time.
