Lower nut 41-2 is arranged on below braced structures 42, and top nut 41-1 is arranged on above fastener.
Between grade beam 20 and single footing 10 end face, reserved leveling space, installs in rear leveling space and arranges ungauged regions material.
Between steel column 30 and grade beam 20, gap is installed, and installs in post gap and arranges ungauged regions material.
Local wharf's pavement quality during prefabricated foundation beam 20 end face in-site installation under column base plate 30-1; After the gap be provided with between each column base plate 30-1 of shear key and prefabricated foundation beam 20, column base plate 30-1 ground installs, there is ungauged regions material to fill.
Embodiment two
Fig. 3 is the assembly concrete foundational system schematic diagram of embodiment three.
Fig. 4 is the partial enlarged drawing of Fig. 3.
As shown in Figure 3 and Figure 4, the present embodiment is two-way assembly concrete foundational system, comprising: single footing 10, prefabricated first foundation beam 20, second grade beam 20-1, steel column 30 and fastening assembly group 40.
Except the structure of first foundation beam 20 and the second grade beam 20-1 is except being connected in the present embodiment, other structures are all identical with embodiment two, no longer repeated description.
Second grade beam 20-1 is mutually vertical with first foundation beam 20.
