In a section steel concrete structure (a stiffened section steel conversion beam), the treatment of a post-cast strip is to disconnect section steel beams in concrete at the post-cast strip, release stress in the construction process and settlement of different parts at two sides of the post-cast strip, connect the steel beams after the settlement is stable, and cast the concrete of the post-cast strip. The following problems thus arise: 1) breaking the stiff steel beam at the post-cast strip; 2) the technical requirements of the post-cast strip steel beam joint; 3) technical precautions in construction; 4) handling of special cases.
The post-cast strip of the concrete structure requires the beam steel bars to be communicated and the concrete is post-cast. However, the section steel in the section steel concrete beam is required to be broken at the post-cast strip to release the uneven settlement, and the conventional technical scheme is that a broken joint is arranged near the center line of the post-cast strip, and the post-cast strip is butted before concrete is filled. The prior art has the defect that only the post-cast strip with small sedimentation is suitable. In the construction of high-rise and super high-rise buildings, the settlement difference between the two sides of the post-cast strip of the main building and the podium building is very large, so that the broken joints and the staggered joints of steel beams are large, the butt joint of the steel beams cannot be aligned, the strength loss is large, and the design requirements are difficult to meet. The invention aims to solve the problem and ensure the strength of the steel beam after butt joint.
