Background
The constructional column is characterized in that in order to enhance the integrity and stability of a building, a reinforced concrete constructional column is arranged in a wall body of a multi-layer brick-concrete structure building and is connected with each layer of ring beam to form a space frame capable of resisting bending and shearing, and the constructional column is an effective measure for preventing a house from collapsing. The arrangement positions of the constructional columns are at four corners of the outer wall, the joints of the cross walls and the outer longitudinal walls at staggered layers, two sides of a larger hole, the joints of the inner wall and the outer wall of a large room, and the like. In addition, the number of layers of the house is different, the earthquake intensity is different, and the setting requirements of the constructional columns are different. The minimum section size of constructional column is 240mm x 180mm, and vertical reinforcing bar is multi-purpose 4 phi 12, and the stirrup interval is not more than 250mm, can suitably increase cross-section and reinforcing bar grade along with the constructional column of intensity and the increase of number of piles four corners of building.
With the rapid development of economy, buildings are higher and higher, high-rise structural floors are generally 120mm thick, wall bodies such as framed walls or walling are generally arranged on the structural floors, the height of the wall bodies is generally about 3m, and the height of a local framed wall can be 6m or even higher. Because the wind load of the high-rise structural floor slab is large, if a high wall is directly built on the roof slab, the stability of the wall body is poor, and therefore structural columns and ring beams are generally arranged in the wall body. However, at the joint of the structural column and the structural floor, the structural floor is thin and cannot meet the anchoring requirement of the longitudinal steel bar in the structural column, so that the structural floor does not have enough constraint force on the structural column, i.e., a stable embedded end cannot be formed. The traditional reinforcing mode of the structural floor slab and the constructional column is characterized in that a reinforcing longitudinal beam and a reinforcing cross beam which are fixedly connected with the constructional column are additionally arranged below a roof so as to meet the anchoring requirement of longitudinal bars in the constructional column. However, the method reduces the height of the indoor roof, namely, the floor height, and influences the quality of the house.
