Description

Technical Field

[0001] The utility model relates to the technical field of pile foundation reinforcement cage positioning, and more specifically to a pile foundation reinforcement cage center control device. Background Art

[0002] The main role of the steel cage is the same as the stress of the longitudinal steel bars of the column. It mainly plays a tensile role. The compressive strength of concrete is high but the tensile strength is very low. It plays a restraining role on the pile concrete so that it can withstand a certain axial tension. When the steel cage is placed in the casing during on-site construction, it is necessary to arrange the steel cage and the casing concentrically. Now, construction workers often use a ruler to measure the distance between the steel cage and the casing, which is difficult to adjust. In addition, when the top of the steel cage is located in the casing and is higher than the top of the casing, it increases the difficulty of positioning the steel cage. For this reason, we propose a pile foundation steel cage center control device. Utility Model Content

A scale 21 is set on the top surface of the measuring rod 20.

[0028] In this embodiment, the distance between the upper limit plate 10 and the inner side of the U-shaped round steel frame 2 is measured by using the scale 21 on the top surface of the measuring rod 20, that is, the distance between the side of the upper limit plate 10 and the inner wall of the casing 1 is measured.
