Problems solved by technology

According to the traditional construction method, although some air vents are left in the design of the square inner corners of the stiffened ribs of the steel beam-column members, during the concrete pouring process, the air here is very difficult to discharge, making the concrete a cavity and quality problems

Embodiment

[0051] The concrete pouring method that a kind of high-rise building steel-concrete composite structure of the present embodiment is used comprises the following steps:

[0052] (1) Install shaped steel columns, shaped steel beams, steel bars and templates;

[0053] (2) if figure 1 As shown, the concrete pouring string tube 2 is installed in the steel column 1;

[0054] (3) Inject cement mortar with a thickness of 50~100mm at the bottom of the steel column;

[0055] (4) According to the cross-section division of the steel column, adopt the method of shifting the pouring progress at the same time, pour concrete into the steel column through the concrete pouring string 2 according to the order of each grid, and vibrate the concrete through the vibrating rod 4 at the same time, Until the height of the concrete in the shaped steel column is 10~20mm higher than the bottom surface of the shaped steel beam; specifically:

[0056] (4-1) If figure 2 As shown, according to the cros...

Abstract

The invention discloses a concrete pouring method for a combined structural steel and concrete structure of a high-rise building. During pouring of structural steel columns, regional pouring and vibration of structural steel columns are conducted in the simultaneous pouring progress staggering advancing mode; and during pouring of structural steel beams, structural steel beams are divided into two sides to be poured and vibrated in the longitudinal dividing mode. The concrete pouring method for the combined structural steel and concrete structure of the high-rise building comprises that simultaneous pouring progress staggering advancing is conducted on all grids according to grid intervals of sections of structural steel columns or structural steel beams, the staggering altitude difference pressure at concrete pouring progresses of all grids is used, gases inside concrete inside structural steel columns and structural steel beams and gases at square internal corner positions formed by stiffening rib steel plates are thoroughly exhausted effectively, the quality problem that cavities exist in the concrete in traditional pouring methods is solved, the compactness of the concrete is guaranteed, and the construction quality of structural steel columns and structural steel beams is improved. The method is reasonable and convenient in construction process, advanced in construction method and reliable in engineering quality and safety.

Description

technical field [0001] The invention relates to the technical field of beam-column structure construction in civil engineering, in particular to a concrete pouring method for a steel-concrete composite structure of a high-rise building. Background technique [0002] With the improvement of architectural design level, people's requirements for high space and wide plane of buildings have become high-end. In addition to the requirements for high space and long span floors, the commercial floors and entrance halls of high-rise buildings also require wall column sections in plane layout. The occupied area is the smallest, and the usable area is the largest, so as to achieve the good effect of building function. These high-space and long-span floors are often located at the bottom of high-rise buildings, and the bearing capacity of beams and columns is large, so the cross-sectional size of reinforced concrete beams and columns is required to increase accordingly. At present, a ne...
