Embodiment Construction

[0040] Examples see Figure 1 ~ Figure 6 As shown, the B1 layer of a certain project is a structural transfer layer, and a rigid concrete frame structure is adopted. It is composed of frame columns and frame beams 9. The frame beams 9 are reinforced concrete beams. The steel bars include beam main reinforcement 7 and beam stirrups. 7 includes long ribs and non-long ribs. The frame beam 9 is connected to the side or top of the frame column. The frame beam 9 is provided with a floor slab. The floor slab and the frame beam 9 are cast as a whole. The frame column is made of core column steel. It is integrated with the surrounding column reinforced concrete structure. The core column steel frame 1 is filled with concrete, and the core column steel frame 1 is covered with studs 2 perpendicular to the surface of the steel frame, and is embedded in the column reinforcement through the studs 2. In the concrete structure 3; the reinforcing bars of the column reinforced concrete structure...

Abstract

The invention relates to a strengthening concrete frame structure. A frame column is formed by integrally pouring a stem steel rib and peripheral column reinforced concretes, wherein the concrete is poured inside the stem steel rib; studs which are vertical to the steel rib are arranged on the periphery of the stem steel rib; the stem steel rib is embedded in the column reinforced concrete structure; the reinforced steel bar in the column reinforced concrete structure comprises a stud, a column stirrup and a drag hook; the beam tendons at the upper part of a beam column joint are a main penetration tendon and a column winding tendon; when the upper column winding tendon passes by the stem steel rib in the frame column, the column winding tendon is bent outwards at a gradient of 1: 6; and when the upper main penetration tendon penetrates a reserved hole on the stem steel rib in the frame column, one end of a lower beam tendon is anchored in the column reinforced concrete structure or is bent upwards. The invention solves the problems that the reinforcing steel bar in the steel rib-concrete structure beam column joint areas is difficult to penetrate the stem steel rib, the concrete is inconvenient to pour and vibrate and the pouring effect is inferior. The structure of the invention can be widely applied to a long span high-rise frame structure.

Description

Technical field [0001] The invention relates to a rigid concrete frame structure and a construction method thereof. Background technique [0002] At present, the commonly used structural form of building structure is steel structure or reinforced concrete structure. Steel structure has disadvantages such as large amount of steel, poor fire resistance, and high maintenance cost. For multi-story and large-span buildings, the cross-section of steel structural members is less than that of reinforced concrete members. Small, the overall stability of the structure is prominent, and the construction workload of reinforced concrete structures is large, especially for multi-high-rise structures. The cross-sections of structural members are too large, resulting in structural self-weight and higher requirements for foundations. Steel-concrete structures have the advantages of steel structures. , It also has the advantages of concrete structure, and the structure has good fire resistance. ...
