6 meters high
Directly with the 110 round tube
You can
12 * 12 square tubes or
10 * 10 can also be a wall must be thick to reach a minimum of 0.28 millimeters, that is, how to say 3 of them.
3 meters or 4 meters a column
Columns under the soil mix 40 * 40 * 50 deep pier, and then welded above the iron plate is best to play directly into the buried parts. You can also hit the concrete when
6 meters under the column welding point of steel, directly loaded inside.
10 of the welded steel can be
Standing column
1.2 meters behind the column
In a pier
Windy
Pier on the big
Also in the middle of the two columns in the middle of the fight
Used to weld
The diagonal braces,
Finally in the middle of the diagonal braces flat
The diagonal braces,
Finally, a flat one in the middle of the diagonal braces
A flat one in the corner of the ground
At least you have to use angle iron
The one in the footer can be pressed against the earth with a forklift
If you use a 50 channel steel
The weld can be more solid.
Billboards with angle iron circle
In the middle of the number of 30CM within the welded square tube
4 * 4 can be, and then directly behind the 60-100CM directly long welding
Don't cut off the welded plane, that will be soft,
Finally, the color of the steel with a 16CM
Small screws directly on the kind of dovetail, 20CM interval can be.
Finally, the colorful steel skin will be put on the dovetailed screws directly with 16CM
.
Finally, the sign is lifted by a crane
Welding U-shaped card with angle iron
Welding
Quickly
Just welding fixed.
Inclined pull brace can be to the sign stand two
Hurry pull two. It is not cost-effective to use people to stand the sign
It takes 4-6 people to lift it
It is also not very safe.
Lastly
Square tube
There is a flat surface on the outside
The billboard is sandwiched between the posts. It can be
Or it can be welded to the outside. It seems to be better sandwiched in the middle
, I use round pipe
3 meters between the columns
welded to the outside, 2 years
still good.
