Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art all belong to the protection scope of the present invention.
As shown in fig. 1-3, according to the utility model discloses a pile foundation steel reinforcement cage positioning and guiding device's structure is demonstrateed, pile foundation steel reinforcement cage positioning and guiding device includes inner truss 1, triangle reinforcing rib 2, arc stopper 4, threaded rod 6, horizontal outer truss 8, vertical outer truss 9, bottom truss 10, can dismantle shaped steel 12. The inner truss 1 and the threaded rod 6 are arranged in two layers, and the bottom truss 10 and the horizontal outer truss 8 at the lowest end form a stable system with the ground through the triangular reinforcing rib plates 2 and the expansion screws 11. The threaded rod 6 penetrates through the through hole 5 of the arc-shaped limiting stopper 4, and two ends of the threaded rod are embedded into the grooves 15 of the inner truss 1 and can freely slide along the grooves. The arc-shaped limiting stopper 4 can freely slide along the threaded rod 6, and two ends of the arc-shaped limiting stopper are fastened by the positioning screws 3. The detachable section steel 12 penetrates through the reinforcement cage 7 to transversely pick up and is fixed on the lower-layer inner truss 1 through bolts 13.
Specifically, the arc-shaped limiter 4 is of a hollow structure, and the inner wall of the arc-shaped limiter is an arc-shaped plate with the curvature slightly larger than that of the steel casing.
