Description

A device for controlling the thickness of the protective layer of steel bars on bridge piers

Technical field

The utility model belongs to the technical field of bridges, and specifically relates to a device for controlling the thickness of the protective layer of steel bars on bridge pier columns.

Background technique

Bridge piers are substructures that support the bridge span structure and transmit dead loads and vehicle live loads to the foundation. Bridge abutments are located on both sides of the bridge. The pier is between the two abutments. The function of the bridge pier is to support the bridge span structure, while the abutment support not only supports the bridge span structure, but also connects with the embankment and prevents embankment slippage.

The existing bridge thickness control device is a fixed device, which is prone to tilting in practice, resulting in a reduction in accuracy. In order to solve this problem, the existing patent "202123157697.8" solves this problem by providing a first splint and a second splint. However, the device still suffers from the following issues:

1. At present, there is no special positioning device when laying out steel bars. The laying out of steel bars is not completely standard in a square shape, but in an irregular shape. The arrangement of this irregular shape must be compared with the device in the document to determine the protection. The thickness of the protective layer of each steel bar cannot be made consistent, making it difficult to support the cylindrical steel formwork and measure and control the thickness. In this case, if in order to meet the unified standard requirements, it will inevitably increase The thickness of the entire protective layer makes the cast bridge piers exceed the standard, and also causes the problem that different piers may have different standards;

2. This device cannot intuitively reflect the thickness of the protective layer, and is not convenient for real-time monitoring during construction.
