Is the pool floor rebar radial?

The pool floor reinforcement circular radial, reinforcement is used for the bottom of the pool, smokehouse foundation and round equipment foundation and other underground parts, he is radial reinforcement from the circle to the outside of the circle segmentation gradually from dense to sparse, uniform distribution. This radial reinforcement is generally two spacing, often marked as C (for radial reinforcement for three-stage steel diameter 18 spacing maximum of 200mm, the most dense for 80mm), to indicate that the radial reinforcement from the outside of the maximum spacing of 200mm gradually extended to the center of the circle, because the more to the arc length of the smaller, so the more the spacing of the steel bar on the denser; can be radial reinforcement when the spacing of less than 80mm, it must be separated from the cut-off one, not cut off the radial reinforcement continues to the center of the circle. The center of the circle extension, when the spacing is less than 80mm, and then a break one, while the other bars continue to extend to the center of the circle, week after week, until the end.

The pool floor rebar round to be radial, the specific calculation method is as follows:

First seek the outer circle of the number of empty bars. The number of empty outer ring (that is, the number of bars) = the maximum arc length of the outer ring / maximum spacing 200mm. (Note that the number of roots do not add 1, because it is a circular arrangement). 3 the length of the bar: the number of empty outer circle * (multiplied by) the minimum spacing of 80mm = the arc length of the location is the location of the 3 bar truncation. So we need to find the length of bar 3 based on this arc length.

The first 3 bar head to the center of the distance: the arc length / circumference / 2 = 3 bar head to the center of the distance, 3 bar length: the center of the circle to the outer skin of the radial bar end distance minus the head of the 3 bar to the center of the distance = 3 bar length, the 3 bar truncated, the 1 bar, the 2 bar continues to extend inward, and then calculate the number of 1 bar + 2 bar a **** of the number of empty. They *** with the number of empty multiplied by 80mm to get the arc length of the location is the location of the No. 2 bar cut off. So according to this arc length to find the length of bar 2.

First of all, you also have to find the distance from the head of bar 2 to the center of the circle. This arc length / circumference / 2 = 2 bar head to the center of the circle, 2 bar length: the center of the circle to the outer skin of the radial bar end of the full length minus the 2 bar head to the center of the circle = 2 bar length. 1 bar length is the length of the member minus the two sides of the protective layer. As for the circular horizontal bar diameter * circumference is not necessary to say. But it should be noted! His form of reinforcement must be a bar spiral lap to the end, so that the material is also easy to construction.
