Problems solved by technology

[0002] In general frame structures, when the column bears a large force, the cross-sectional size is generally large, which not only wastes materials, but also occupies a large area; when the beam bears a large force, not only the cross-sectional size is large, but also In order to meet the requirements of the allowable relative compression zone height, the reinforcement in the compression zone is generally dense, which not only wastes materials, but also makes construction difficult, and it is difficult to guarantee the quality of the project; controlled by shear capacity

specific Embodiment approach 1

[0005] Specific implementation mode one: (see Figure 1-Figure 4 ) This embodiment consists of a frame beam 1, a frame column 2 and a frame node 3, the cross-sectional compression zone of the frame beam 1 is composed of high-strength or ultra-high-strength concrete, and the cross-sectional tension zone of the frame beam 1 is composed of ordinary concrete; the frame The column 2 has a built-in high-strength or ultra-high-strength concrete core column 2-1, and the frame node 3 is composed of high-strength or ultra-high-strength concrete.

specific Embodiment approach 2

[0006] Specific implementation mode two: (see Figure 1-Figure 4 ) The difference between this embodiment and specific embodiment 1 is that the mid-span compression zone 1-1 of the frame beam 1 is high-strength or ultra-high-strength concrete; the support compression zones 1-2 at both ends of the frame beam 1 are high-strength or ultra-high-strength concrete concrete. Other compositions and connections are the same as in the first embodiment.

[0007] The implementation steps of the different-strength concrete frame structure of the present invention are: 1. pour the core column 2-1 first, and when the concrete of the core column 2-1 is hardened, support the formwork to tie the ribs and pour ordinary concrete on the periphery to form a built-in high-strength or Reinforced concrete frame column 2 of ultra-high-strength concrete core column 2-1; 2. Pouring high-strength or ultra-high-strength concrete frame joint 3; 3. First pouring high-strength or ultra-high-strength concrete...

Abstract

The present invention is one specific reinforced concrete frame structure, relates to reinforcing bar concrete frame in civil engineering, and aims at reducing cross section size of beam and column and decreasing reinforcing bars in reinforced concrete frame structure. The frame beam has cross section pushing area of high strength or ultra high strength concrete and cross section pulling area of common concrete; the frame column has core column of high strength or ultra high strength concrete; and frame node is made of high strength or ultra high strength concrete. The present invention has reduced beam and column cross section size, decreased reinforcing bars, convenient construction, high engineering quality and improvement in the use function of building or structure.

Description

technical field [0001] The invention relates to a reinforced concrete frame structure in the field of civil engineering. Background technique [0002] In general frame structures, when the column bears a large force, the cross-sectional size is generally large, which not only wastes materials, but also occupies a large area; when the beam bears a large force, not only the cross-sectional size is large, but also In order to meet the requirements of the allowable relative compression zone height, the reinforcement in the compression zone is generally dense, which not only wastes materials, but also makes construction difficult, and it is difficult to guarantee the quality of the project; controlled by shear capacity. Contents of the invention [0003] In order to avoid problems such as larger beam-column section size and more reinforcement in general frame structures, the invention provides a frame structure of hetero-strength concrete, which includes frame beams 1, frame c...
