What will happen when sending steel bars to the construction site, and how to solve them, it should

1. Site problems, if a large number of steel bars arrive at the scene, you must first step on the site. In addition, if there are construction sites close to residential buildings, some wires are pulled very low, and the height of the torii may be restricted.

2. Cranes, cranes are needed to unload steel bars, and the crane must be contacted in advance, and the tonnage must be clear first. If you also have to crane to enter the site, you will also encounter the first problem.

3. When buying steel bars, it is best for the material staff to follow the whole process, so as not to buy the best steel bars, and the steel bar sellers are shoddy.

4. When you weigh it, you should see the weight clearly and collect the weighing list.

5. It is necessary to see the steel bar cutting list clearly, so as not to buy duplicates and not waste resources.

There are many miscellaneous things that I will not give examples.

Generally, when you go to the construction site, the receiver on the construction site will ask you for the quality certificate of the rebar and the certificate of conformity of the rebar.

It is the iron brand on the above to see whether the furnace batch number, batch number and the number on the steel bar are correct Generally, the steel bar with a larger diameter is counted one by one When you count it, you should look at it so as not to miss it You must know it yourself and remember the number yourself so as not to forget it when you get it! That's about it!

I've done this, hehe, very tired, dizzy.

In addition to the various certificates, batch numbers, certificates, etc., the easiest thing to rip off is the problem of pound difference, that is to say, the weight of your car of steel factory, and the weight of getting off the car at the scene is not the same, some are black-hearted delivery halfway sold, some are two said that one is not standard, this kind of thing no one dares to say whether they are right, anyway, most of them are more or less a little bit bad.

According to the drawings, there is no formula at all, just calculate the length, addition, subtraction, multiplication and division. The stirrup encryption area is calculated separately from the non-encrypted area, and the length of the main reinforcement is divided by the stirrup spacing designed in the drawing, and the circumference of each circle is calculated, and then multiplied. The length of the main reinforcement should be calculated directly on the drawing, and the length of the protective pile head should be included on the drawing (generally).

Just take a closer look at the drawings.

Are you a construction? Or is it design?

If you are doing construction, there is a list of reinforcement at the back of this drawing.

If you want to do a design, you must first calculate it, and then arrange the reinforcement (main reinforcement, the vertical thick steel bar in the figure).

There are only 4 kinds of reinforcement in this structure: main reinforcement, there are two lengths, the first is from the pile top + cushion cap embedded length to the pile bottom (minus the pile bottom isolation height of 5cm); The second is based on the calculation, the pile does not need to be configured a lot, and it is rolled short; Reinforcing hoop, placed in the main reinforcement, the reinforcement ring positioned as the main reinforcement, 2 meters apiece; Annular stirrups, from the top of the pile to the bottom of the pile, ring to the bar that holds the main bar together; Positioning ribs, in order to make the reinforcement cage lower so that it can be correctly positioned and the concrete has a protective layer in the future, a reinforcement support ear will be added to the periphery of the reinforcement cage.

The above reinforcement calculations are very simple, and they can be calculated in junior high school mathematics, as long as you can understand the drawings.

Use rebar lofting software and you're done in a few minutes.

There may be a problem with the travel switch, try replacing one.

960 meters of steel bars in the pool above the ground, and 506 meters in the pool below the ground.

The volume of your pool is not small, if it is filled with water, there are 40 tons, if it is built on the surface, the strong pressure outside it is nearly 30 tons, if you simply build a wall, I am afraid it will be difficult to bear, if there is a force to add steel to beat concrete.

This depends on the degree of detachment of the cement block, and the problem is not clear whether the steel bar on your balcony is exposed or the steel bar on your upper floor.
