Description

Technical Field

[0001] The utility model belongs to the technical field of building raft slabs, and in particular relates to a high-strength steel bar raft slab foundation structure. Background Art

[0002] The application of high-strength steel bars in raft foundation can solve the problems of fat beams and columns, steel congestion, etc. in construction projects. This will increase the usable area of ​​the building while making the raft foundation structure design more flexible, expand the use function of the raft foundation structure, and thus improve the use function of the building. It can also be used in conjunction with high-strength concrete to achieve the advantages of reducing the dead weight of the structure, avoiding the dense configuration of steel bars, and facilitating construction, which greatly improves the quality of the building, reduces maintenance costs, and can greatly reduce the amount of steel bars used. The economic benefits are obvious, and the high-strength steel bars have good mechanical properties, which ensures the quality of the project and meets the specifications and design requirements.

[0003] The high-strength reinforced raft slab adopts controlled binding and controlled cooling technology as well as a herringbone reinforcement form, which can not only improve the strength of the steel bars but also maintain good ductility, meet the requirements of using high-strength steel bars in the raft foundation structure, improve the integrity of the raft foundation, reduce shrinkage cracks of the raft foundation, and prevent local block falling of the raft foundation.

[0004] The existing reinforced raft foundation structure is generally connected to the steel bars by overlapping, that is, two steel bars are laid flat together, and then stacked in the middle for a certain length, and the two steel bars are connected by bundling, or the crossed steel bars are connected by welding or bundling. This method is relatively stable, but it is difficult to construct. Multiple steel bars need to be bundled together. Since both ends of the steel bars are not fixed, welding or bundling requires lifting the steel bars to weld or bundle at the intersection, and the stability of the intersection is also poor.
