<\/p>\nHello, everyone<\/p>\n
This is Enta.<\/p>\n
Do you know the basic principles of rebar installation?<\/p>\n
You know how sometimes they pour concrete here, but not there?<\/p>\n
<\/p>\n
As long as the director is aware of the situation, there\u2019s no particular problem, but there are often times when I wonder, \u201cWhat should we do about this?\u201d or,<\/p>\n
There are times when you can\u2019t really say anything until you check with the government office, right?<\/p>\n
What do you do in situations like that?<\/p>\n
That's the point.<\/p>\n
<\/p>\n
In the case of rebar insertion work, the basic question is: How many bars are installed in the analysis cross-section (standard cross-section)?<\/p>\n
That's it!<\/p>\n
<\/p>\n
For example, suppose a standard cross-section shows five rebar inserts.<\/p>\n
Generally speaking, the starting point is about 0.5 m to 1.0 m below the legal shoulder.<\/p>\n
If there are load-bearing panels, such as green panels, the spacing starts at approximately 1.5 m, and the pitch (interval) varies from approximately 1.0 m to 4.0 m.<\/p>\n
<\/p>\n
There are five of them installed at 1.5-meter intervals, and the total length is about 7 meters.<\/p>\n
1.5 m spacing \u00d7 4 bars + 1 bar (outer) + 1.0 m top and bottom = 7.0 m<\/p>\n
<\/p>\n
So, the standard configuration is five rods for this 7.0m length.<\/p>\n
However, if there is a section that exceeds 7.0 meters and allows for six piles to be driven, the sixth pile will be driven.<\/p>\n
The reason is that if it\u2019s possible to hit the sixth pitch, not doing so would make the situation unstable.<\/p>\n
<\/p>\n
Conversely, if there\u2019s too much of something, you just need to reduce it.<\/p>\n

<\/p>\n
Also, depending on the designer, there may be cases where the outer perimeter is also poured, so please follow the design specifications.<\/p>\n
<\/p>\n
The part with the \"mago\" is actually quite difficult.<\/p>\n
The number of bars in the vertical direction is determined by the design cross-section.<\/p>\n
Please decide whether or not to place a formwork support at every 1.5 meters along the horizontal span. (Assuming the spacing used in the example above)<\/p>\n
For example, if the total length is 20 m, 20 \u00f7 1.5 m = 13.3 pieces + 1 piece (extra), for a total of 14 pieces.<\/p>\n
If we consider only the horizontal direction, we can determine whether a mago can be placed there or not even by extending the line horizontally.<\/p>\n
I think managing things vertically is fine, but if you're unsure whether to include something or not, try thinking about it in terms of horizontal expansion.<\/p>\n
<\/p>\n
It means it\u2019s okay as long as we submit the agreement based on those layout drawings and concrete placement plans.<\/p>\n
There are no specific rules regarding the horizontal direction, so as long as everything adds up, it will generally be accepted.<\/p>\n
<\/p>\n
Next, make sure you clearly understand the pouring locations, and mark the areas where voids are to be left in the formwork and the pouring locations in accordance with the drawings.<\/p>\n
