Description
Technical Field
The invention relates to a building construction method, in particular to a method for checking and controlling the length of a straight section of a blanking hook of a reinforcing steel bar in building engineering.
Background
The straight section length of the blanking hook of the construction engineering reinforcing steel bar has different requirements, namely, 3d, 5d, 10d, 12d and the like, when the hook angles are different at 90, 135 and 180 degrees, the types of the reinforcing steel bars are different, whether the steel bars are in earthquake-resistant design or not, and the positions of the reinforcing steel bars are different. In the conventional construction, because the length of the straight section is not well measured, no matter a steel bar processing worker or a quality inspector masters a poor measurement standard, the length of the straight section of the steel bar hook is not well controlled, and the length is not long or short.
Disclosure of Invention

The invention adopts the following technical scheme for solving the technical problems:
a method for checking and controlling the length of a straight section of a blanking hook of a construction engineering reinforcing steel bar comprises the following steps:
A. preparing a steel bar to be detected, and checking the specification d of the steel bar;
B. checking a steel bar material table, determining the use position of a steel bar to be detected, and determining the length requirement a of the straight section of the hook of the blanking steel barTheory of thingsAnd a camber diameter D;
C. calculating theoretical measurement length b of to-be-detected steel barTheory of things＝aTheory of things+D/2+d；
D. Placing an arc top baffle plate, wherein the arc top baffle plate 3 is tangent to an outer arc of the bent reinforcing steel bar and is perpendicular to the straight section of the blanking hook;
F. using the end of the ruler to jack the baffle plate at the top of the arc, reading the actual measurement length bFruit of Chinese wolfberry；
G. Calculating the length deviation of the actual blanking straight section as aFruit of Chinese wolfberry-aTheory of things＝bFruit of Chinese wolfberry-bTheory of things；
F. And determining whether the deviation is qualified or not, wherein the deviation is a positive deviation, and judging that the length of the straight section of the steel bar hook meets the requirement, otherwise, the length does not meet the requirement.
Compared with the prior art, the invention adopting the technical scheme has the beneficial effects that:
by arranging the arc top baffle, the arc radius tangent line which is easier to search is taken for indirect measurement, so that the measurement is more accurate, and the method is simple and practical.
