Description

A device for measuring and controlling the thickness of the protective layer of structural beams

technical field

The utility model belongs to the technical field of construction detection equipment, in particular to a device for measuring and controlling the thickness of a protective layer of a structural beam.

Background technique

Structural beams refer to load-bearing components that mainly play a role in lateral support in building structures, mainly including frame beams, coupling beams, frame support beams and other structures. Effective anchorage is very important; if the protective layer is too thin, moisture and water will easily enter the concrete; if the protective layer is too thick, the concrete will easily crack and lead to corrosion and expansion of steel bars, which poses a great threat to the use of concrete and structural safety;

Therefore, in the construction process of the main structure, the control of the concrete cover is particularly important. In the process of binding the structural beam reinforcement and formwork support, due to the scaffolding installed at the lower part of the structural beam, the space under the structural beam is limited, and it is impossible to install it from the lower part of the structural beam. The thickness of the protective layer of the structural beam is measured, so the measurement methods currently used for the thickness of the protective layer of the structural beam mainly include:

1. Extend the ruler from the upper part of the structural beam to the lower part of the beam to measure the thickness of the lower protective layer of the structural beam. In the actual measurement process, due to the blocking effect of the installed scaffolding and formwork, it is difficult for the construction personnel to read. The interference is large, so that the construction personnel can only take a rough reading, so it is impossible to effectively measure the thickness of the protective layer on the lower side of the structural beam from the upper side of the structural beam;

2. Measure the thickness of the lower protective layer of the structural beam with a level and a leveling rod. Although this method can accurately measure the thickness of the protective layer on the lower side of the structural beam, it needs to be mounted on the structural beam that has been bound with steel bars when using it. The vertical level and the leveling rod that needs to be carried by the construction personnel move back and forth on the steel frame, which has a high risk factor and low measurement efficiency. Therefore, it is also impossible to effectively measure the thickness of the protective layer on the lower side of the structural beam from the upper side of the structural beam. ;

Therefore, there is an urgent need to design a device for measuring and controlling the thickness of the protective layer of structural beams with a simple and practical structure, so as to solve the above-mentioned problems in the prior art.
