Foundation underpinning structure of heavy bent frame and construction method of foundation underpinning structure
The invention belongs to the technical field of civil engineering, and relates to a foundation underpinning structure of a heavy bent and a construction method thereof. According to the technical scheme, a steel-clad structure is arranged and comprises externally-wrapped angle steel, externally-attached steel bars, externally-attached steel plates and angle steel shear keys; the column foot structure comprises a steel supporting plate, a steel plate bracket and a column foot bolt; and a joist and an underpinning pile are additionally arranged. And the joist surrounds the outer side of the steel-clad structure and is tightly attached to the steel-clad structure. The column foot structure is arranged at the top of the joist and connected with the externally-attached steel plate of the steel-clad structure, high support rigidity is formed, and the stability of the framed bent structure is guaranteed. And finally, the heavy bent frame column can transmit the structural load to the newly arranged pile foundation through the underpinning structure, the original foundation of the bent frame column is cut, and foundation underpinning is completed. Compared with a traditional underpinning structure, the bearing capacity and the support rigidity are higher, construction is easy and convenient, universality is high, and obvious technical advantages are achieved under the condition that the implementation height of the joist is limited.
本发明属于土木工程技术领域一种重型排架的基础托换构造及其施工方法。技术方案为：设置包钢构造包括外包角钢、外贴钢条、外贴钢板、角钢抗剪键；设置柱脚构造包括钢支承板，钢板牛腿、柱脚螺栓；另设置托梁及托换桩。将托梁环绕于包钢构造外侧，并与包钢构造密实贴合。柱脚构造设置于托梁顶部，并与包钢构造的外贴钢板连接，形成较强的支座刚度，确保了排架结构的稳定性。最终重型排架柱可通过该托换构造将结构荷载传递至新设置的桩基础，进行排架柱原始基础切割并完成基础托换。其具有高于传统托换构造的承载力及支座刚度，施工简便，通用性强，在托梁实施高度受限的情况下，具有较明显的技术优势。
