Background
The steel bar engineering is the most important in building construction, and is widely applied to building construction at present. The manufacturing and binding quality of the steel bars determine the key of the quality of the building structure. With the progress of metallurgical technology, building steel with high compressive strength and compressive strength, good ductility and uniform quality is widely applied, and due to low price, convenient material taking and good performance, civil engineering enters the historical period that reinforced concrete and prestressed concrete occupy the domination, and in general engineering, the percentage of reinforced concrete in the whole project is over half.
In the reinforced concrete, the importance of the steel bar spacing is particularly important, the cost and the structure dead weight are increased due to the fact that the steel bar spacing is too close, the cohesion force between the concrete is difficult to guarantee due to the fact that the steel bar spacing is too large, designers specify the steel bar spacing based on the cohesion force of the concrete and the consideration of the size of aggregates when the concrete is poured, and the steel bar spacing of various members such as beams, plates and columns is specified differently in relevant specifications such as concrete structure design specification and the like through calculation in the aspect of structures.
The steel bar interval refers to the horizontal distance between the steel bar centroid, also there is not the distance of difference in height, common structure steel bar interval is 10cm, 15cm, 20cm, 30cm, and the standard deviation value is in plus or minus 1cm mostly, reinforcement in-process and completion back, the constructor will carry out the self-checking to the steel bar interval and report the supervision acceptance, the acceptance back can get into next process, current steel bar interval measurement all measures the distance through drawing straight chi or tape measure, the ruler tip is given for the steel bar center difficulty, it can obtain the deviation value to calculate during the reading, this mode operation is inconvenient, and the precision is not high, for this reason, we propose a civil engineering range finder.
