Embodiment 1

[0038] Such as Figure 1 to Figure 7 As shown, a giant steel pipe concrete column pouring and tamping device 10 is used for the pouring construction of the concrete conduit in the giant steel pipe column 20. The giant steel pipe column 20 is inserted with a number of pouring and tamping conduits 30, and the outer wall of the pouring and tamping conduit 30 is provided with vibration Rod catheter 40. The vibrating rod conduit 40 includes a vibrating machine hose 42 at the upper end and a vibrating rod 41 at the lower end, so that the aggregate is evenly distributed in the concrete member, thereby ensuring the pouring quality of the giant steel pipe concrete column. The pouring and tamping device 10 includes: a limiting plate 50 and a buckling fixture 60 . The lower end of the limiting disc 50 is embedded in the upper port of the giant steel pipe column 20 , and the limiting disc 50 is provided with a plurality of limiting holes 51 through which the pouring and ramming conduit 3...

Abstract

The invention relates to a huge concrete filled steel tubular column core grouting pouring and tamping device and method, and belongs to the technical field of building construction. Problems that in construction of pouring and tamping a huge concrete filled steel tubular column core by using a multi-guiding-tube method, positions of a plurality of guiding tubes are not fixed in the horizontal direction, vertical lifting is not uniform, and heights are not determined are solved. The pouring and tamping device comprises a limiting plate and fastener clamps, wherein the limiting plate is inlaid in an upper port of a huge steel tubular column and is provided with a plurality of limiting holes; pouring and tamping guiding tubes can penetrate in the limiting holes; and the fastener clamps fixedly sleeve the outer walls of the pouring and tamping guiding tubes. The pouring and tamping method comprises the following steps: firstly, fixedly positioning the huge steel tubular column; secondly, mounting the limiting plate on the huge steel tubular column, arranging the fastener clamps and fixing seats on the outer walls of the pouring and tamping guiding tubes, and placing the pouring and tamping guiding tubes in the huge steel tubular column through the limiting plate; thirdly, pumping concrete in the huge steel tubular column through the pouring and tamping guiding tubes, and slowly and synchronously raising the pouring and tamping guiding tubes and vibration bar guiding tubes while pumping; and finally, detaching the pouring and tamping device after concrete pouring of the huge concrete filled steel tubular column is finished.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a device and method for pouring and tamping the core of a giant steel pipe concrete column. Background technique [0002] With the development of the construction industry and the increase of building height, ordinary-sized concrete-filled steel tube columns can no longer adapt to the huge bearing capacity of super high-rise buildings, while giant concrete-filled steel tube columns have high bearing capacity, good seismic performance, and convenient construction. The application is more and more extensive. [0003] The giant concrete-filled steel tube column has its unique advantages, but its construction is difficult, especially the pouring and tamping of the core concrete of the giant steel tube concrete-filled column is difficult, and the construction quality is difficult to guarantee. There are two main methods of pouring and tamping widely used in my country: ...
