Design method of ultrahigh-strength steel sleeve for prefabricated concrete structure and grouting connection device
The invention discloses a design method of an ultrahigh-strength steel sleeve for a prefabricated concrete structure, and belongs to the technical field of prefabricated concrete structures. The design method comprises the following steps of calculating anchoring length needed by a stressed steel bar; determining the optimal wall thickness of the wall of an ultrahigh-strength sleeve; calculating the number and the size of shear keys; designing a welding end face and a welding process; the ultrahigh-strength steel sleeve is adopted, the yield strength of steel is greatly improved, the use amount of sleeve steel can be greatly reduced, emission of carbon dioxide in the steel production process is reduced, the designed sleeve size can greatly reduce the wall thickness of the sleeve, and under the condition that it is guaranteed that the outer diameter of the sleeve is not changed, the inner diameter of the ultrahigh-strength steel sleeve is larger than that of a common sleeve, the allowable error of the inner diameter of the sleeve is greatly increased, the mortar structure formed by pouring the super-hydrophobic flexible grouting material has super-high flexibility, the welding technology is adopted, and complex program steps are avoided.
本发明公开了预制装配式混凝土结构技术领域的一种预制装配式混凝土结构用超高强度钢制套筒设计方法，包括以下步骤：计算受力钢筋所需的锚固长度；确认最佳超高强套筒筒壁壁厚；计算剪力键的数量和尺寸；设计焊接端面及焊接工艺；本发明采用了超高强钢材套筒，大大提高了钢材的屈服强度，可以大幅减少套筒钢材量的使用，减少了生产钢材过程中二氧化碳量的排放，本发明设计的套筒尺寸，可以大幅减小套筒壁厚，在保证套筒外径不变的条件下，超高强钢材套筒内径要比普通套筒增加，大大增加套筒内径允许误差，本发明采用超疏水柔性灌浆料灌注形成的砂浆结构，具有超强的柔韧性能，本发明采用焊接工艺，避免了繁杂的程序步骤。
