Steel pipe bundle connecting structure
The invention discloses a steel pipe bundle connecting structure. The steel pipe bundle connecting structure comprises a plurality of steel pipe bundle units which are connected in pairs, wherein a connecting plate is arranged at the end part of each steel pipe bundle unit; during connection, the connecting plate of the previous steel pipe bundle unit is overlapped with the connecting plate of the next steel pipe bundle unit; corresponding assembly holes are formed in the two connecting plates respectively; a shear-resistant bolt is screwed into each assembly hole from the outer side of a steel pipe bundle; each shear-resistant bolt comprises a screw rod and a bolt head; each screw rod is sequentially divided into a blade section, a thread extrusion section and a thread expansion fit section from the end part far away from the bolt head along the length direction of the screw rod; the assembly holes of the two connecting plates are cut by the blade sections to be consistent in concentricity; the hole walls are extruded and expanded by the action of the thread extrusion sections to form internal threads which are in gapless fit with the thread expansion fit sections; templates are also arranged on the outer sides of the connecting plates; the templates and the connecting plates are arranged in a clearance manner; groove cavities are formed between the templates and the connecting plates; the bolt heads of the shear-resistant bolts are positioned in the groove cavities; and concrete is poured into the groove cavities.
本发明公开了一种钢管束连接结构，其包括若干个两两衔接的钢管束单元，每个钢管束单元的端部设置有连接板，衔接时，上一个钢管束单元的连接板与下一个钢管束单元的连接板叠靠，且两个连接板上分别开设有对应的装配孔，自钢管束的外侧向每个装配孔中拧入抗剪螺栓，抗剪螺栓包括螺杆和螺栓头，螺杆上自远离螺栓头的端部并沿着螺杆的长度方向依次分为刀刃段、挤螺纹段、螺纹胀紧配合段，两个连接板的装配孔由刀刃段切削成同心度一致，并由挤螺纹段作用将孔壁挤扩成型出与螺纹胀紧配合段无间隙配合的内螺纹，连接板的外侧还设置有模板，模板与连接板间隙布置，两者之间形成槽腔，各个抗剪螺栓的螺栓头位于槽腔中，槽腔中浇筑有混凝土。
