Split mounting type precast concrete foundation
The invention relates to a split mounting type precast concrete foundation which comprises a first edge concrete precast block, a second edge concrete precast block and at least one middle concrete precast block located between the first edge concrete precast block and the second edge concrete precast block during use. At least one middle concrete precast block is a foundation concrete precast block with the upper end provided with a precast supporting column or a reserved joint bar, and shear keys and shear key groove structures which are matched in a concave-convex mode are arranged between the adjacent side faces of the adjacent concrete precast blocks. The split mounting type precast concrete foundation further comprises a plurality of prestressed tendons connected between the concrete precast blocks in a penetrating mode in the arrangement direction of the concrete precast blocks, and the two ends of the prestressed tendons are fixedly connected with the concrete precast blocks on the corresponding edges through fixing structures respectively. The technical problem that a cast-in-place structure is adopted for an existing concrete foundation, and a construction site is prone to being polluted is solved.
本发明涉及一种拼装式预制混凝土基础，包括第一边缘混凝土预制块、第二边缘混凝土预制块及使用时位于第一边缘混凝土预制块、第二边缘混凝土预制块之间的至少一个块中间混凝土预制块，其中至少一个中间混凝土预制块为上端设置有预制支撑柱或者预留插筋的基础混凝土预制块，相邻的混凝土预制块的相邻侧面之间设置有互相凹凸配合的剪力键、剪力键槽结构，拼装式预制混凝土基础还包括多根沿各混凝土预制块排布方向穿连于各混凝土预制块之间的预应力筋，预应力筋的两端分别通过固定结构与对应边缘混凝土预制块固定相连。本发明解决了现有混凝土基础采用现浇结构容易污染施工现场的技术问题。
