Large roller bed foundation structure and construction and installation method
The invention discloses a large roller bed foundation structure and a construction and installation method. The large roller bed foundation structure comprises foundation bolt assemblies embedded in roller bed ground beams at equal intervals. Shear pits are dug in the roller bed ground beams on the front sides and the rear sides of the foundation bolt assemblies, and bedding mortar block sets are poured in the roller bed ground beams on the front sides and the rear sides of the foundation bolt assemblies. The elevations of the tops of the bedding mortar block sets are consistent. The construction method of the large roller bed foundation structure comprises the steps that foundation bolts and shear pit formworks are erected and reinforced in a reinforcing mesh in a ground beam formwork, the roller bed ground beams are poured in the ground beam formwork, the bedding mortar block sets are poured and steel base plates are embedded in the roller bed ground beams through bedding mortar molds, and the steel base plates are corrected to be at the same elevation. The installation method of a large roller bed comprises the steps that the roller bed is hoisted to the position over the roller bed ground beams in a segmented mode, bolt holes are drilled in a steel beam lower flange plate, cross-shaped shear-resistant embedded parts are welded to the steel beam lower flange plate, the cross-shaped shear-resistant embedded parts are inserted into the shear pits, the foundation bolts penetrate through the bolt holes to be in place, the tightness degree of the steel beam lower flange plate and the steel base plates is checked through a feeler gauge, and the thin steel base plates are inserted into the large gaps.
本发明公开了一种大型滚床基础结构及施工、安装方法，大型滚床基础结构包括等距间隔埋设于滚床地梁上的地脚螺栓组件，各地脚螺栓组件前、后侧的滚床地梁上挖设有抗剪坑和浇筑有坐浆块组，各坐浆块组顶部的标高一致；大型滚床基础施工方法是于地梁模板内的钢筋网中支设加固地脚螺栓及抗剪坑模板，于地梁模板内浇筑滚床地梁，在滚床地梁上采用坐浆模具浇筑坐浆块组及埋设钢垫板，校正钢垫板处于同一标高；大型滚床安装方法是将滚床分段吊运至滚床地梁正上方，在钢梁下翼缘板上钻螺栓孔和焊接十字抗剪埋件，将各十字抗剪埋件插入抗剪坑和将地脚螺栓穿过螺栓孔而就位滚床，采用塞尺检查钢梁下翼缘板与钢垫板的紧密程度，在空隙较大处插入薄钢垫板。
