H-shaped steel-RC step pile variable cross-section joint connection structure and construction method thereof
The H-shaped steel-RC step pile variable cross-section node connection structure comprises H-shaped steel and a reinforced concrete pile, the bottom of the H-shaped steel is inserted into the reinforced concrete pile to form a combined pile, and the front end and the rear end of a flange at the bottom of the H-shaped steel are each connected with a steel plate strip with holes; a plurality of holes are formed in the side walls of the four perforated steel plate strips at intervals from top to bottom, and the four holes located in the same horizontal plane are called hole layers; transverse connecting steel bar layers and annular connecting steel bar layers are alternately arranged on the multiple hole layers. The H-shaped steel and the reinforced concrete piles are poured into a whole through the combined piles through the transverse connecting steel bars and the annular connecting steel bars. The four corners of the top of the reinforced concrete pile are wrapped with angle steel respectively, and batten plates are connected among the four angle steel. The invention further provides a construction method of the H-shaped steel-RC step pile variable cross-section joint connection structure. The variable cross-section node of the stepped pile can be reinforced, and the horizontal deformation capacity of the top of the stepped pile is improved.
H型钢‑RC阶梯桩变截面节点连接的构造，包括H型钢和钢筋混凝土桩，H型钢的底部插入钢筋混凝土桩内形成组合桩，H型钢底部翼缘的前后两端分别连接有一个带洞钢板条；四个带洞钢板条的侧壁分别由上至下间隔设置有多个孔洞，将位于同一水平面上的四个孔洞称为孔洞层；多个孔洞层上交替设置有横向连接钢筋层和环向连接钢筋层；组合桩通过横向连接钢筋和环向连接钢筋将H型钢和钢筋混凝土桩浇筑为一体；和钢筋混凝土桩的顶部四角处分别包裹有角钢，四个角钢之间连接有缀板。本发明还提供一种H型钢‑RC阶梯桩变截面节点连接的构造施工方法。本发明可以加固阶梯桩变截面节点，提高阶梯桩桩顶水平变形能力。
