Embodiment Construction
[0038] Such as Figure 1 to Figure 4 As shown, the recyclable fully prefabricated pile top crown beam of the present invention is arranged on the top of support piles 1, and spliced sequentially to connect adjacent support piles 1.
[0039] The crown beam 2 is a rectangular parallelepiped reinforced concrete structure. An anchor hole 3 is vertically arranged on the crown beam 2. The anchor hole 3 corresponds to the connecting anchor cable 4 pre-buried on the top of the support pile 1. The anchor hole 3 is an oblong through hole. Holes, the length of which is not less than 150mm, the connecting anchor cables 4 are steel strands, the length and number of embedded concrete are mainly determined according to the anchoring force provided by the design, and 1-2 bundles of connecting anchor cables can be set in each supporting pile 1 4. The connecting anchor cable 4 passes through the anchor hole 3 vertically, and is locked and fixed by the anchor 5. A steel backing plate 6 is arra...
