Problems solved by technology

[0002] At present, in the process of bridge construction, some bridge piers spanning non-navigable holes are prefabricated piers. When installing pier bodies, the flatness of the cap interface and the precision of the pre-embedded pier body reinforcement are relatively high. However, the existing construction methods usually Using manual measurement to determine the height of the pre-embedded pier body reinforcement, there is a certain measurement error, and the accuracy cannot be well guaranteed
There are also some units that use special equipment to achieve the above flatness and precision control, but the structure is too complicated and the cost is high

Abstract

The invention discloses a high-precision suspension-type embedded reinforcement positioning rack structure and a method for calibrating the flatness of a connection face of a hole bridge pier body through the structure and relates to the field of civil engineering equipment. The structure comprises an upper frame, a lower frame, a vertical connector and a center support, the upper frame and the lower frame are of a rectangular frame structure and are fixedly connected through the vertical connector to an outer frame, and an I-shaped steel beam is fixedly welded to the inner side of the cornerof the outer frame; the center support comprises an octagon frame, a horizontal connector and a forked connector, and the upper frame, the lower frame and the octagon frame are also provided with multiple vertical through holes. According to the structure, by manufacturing a modularization positioning rack as a control measure for the flatness of the connection face of the bearing table pier bodyand the precision of embedded pier body reinforcement, the flatness of the connection face of pier body installation and precision of height parameters are improved, the construction quality is guaranteed, the construction process is also simplified, and after the levelness is guaranteed, the height of the structure can be timely adjusted just by adjusting the height of the positioning rack.

Description

technical field [0001] The invention belongs to the field of civil engineering equipment, in particular to a suspended pre-embedded steel bar positioning frame structure with simple structure, convenient construction and high precision. Background technique [0002] At present, in the process of bridge construction, some bridge piers spanning non-navigable holes are prefabricated piers. When installing pier bodies, the flatness of the cap interface and the precision of the pre-embedded pier body reinforcement are relatively high. However, the existing construction methods usually Using manual measurement to determine the height of the pre-embedded pier body reinforcement, there is a certain measurement error, and the accuracy cannot be well guaranteed. There are also some units that use special equipment to achieve the above-mentioned flatness and precision control, but the structure is too complicated and the cost is high. Contents of the invention [0003] The object of...
