Solve the doubt: Why do you have to lay the bricks diagonally when building the final wall instead of straight?
Have you ever noticed when walking past a construction site or watching a home renovation clip on TikTok that the workers build a wall all the way to the top. But when they reach the top, they lay the bricks diagonally instead of laying them straight like they always do? Many people are confused and wonder, “Why don’t they lay them neatly like before?” Actually, there is a reason why the workers do that. It’s not that they are lazy or haphazard.
Today, we will answer your questions in an easy-to-understand way. After reading, you will understand immediately. “What is a diagonal line and why do we have to do it?” For those who are wondering, we have found the answer for our friends.
Solve the doubt: Why do you have to lay the bricks diagonally when building the final wall instead of straight?
The short answer is For strength. The bricks must have a 10 cm space left under the beam and then wait for the brick wall to collapse for 1-2 days. After that, lay the bricks at a 45 degree angle or stuff the heads of the fish bones. This type of brick laying will reduce the pressure. If the beam falls down, the wall will not crack.
But if you want to explain it clearly and easily. You have to look at the overall picture of the wall. When the wall is as high as the beam (which is the top structure that supports the weight). If the worker places the bricks straight up and hits the beam exactly. It will create pressure from the wall to push the สมัคร UFABET วันนี้ รับเครดิตฟรีสำหรับสมาชิกใหม่ beam directly. And the beam will push back at the wall with force like playing ping pong. Finally, when the wall moves even a little, it has the right to crack easily, especially at the top edge.
Laying the bricks at an angle creates a “gap” that allows the craftsman to gradually fill in the mortar without over-packing or pushing the beam. This is a technique called “slanted shoulder” or “closing the wall head”.
And is it strong just by tilting it?
It’s not like it’s finished just by laying the bricks at an angle. Normally, after laying the bricks at an angle. The technician will use cement to fill the gap and then apply a mixture of cement and sand to make the wall stick to the beam well, but not push too hard. If it’s pressed well, it will be as strong as a normal wall and will also reduce the chance of cracking in the long run.
Why not use other materials to cover it instead?
Some people may think that using foam, lightweight cement, or anything to fill the gaps will be faster, right? It is true, but it is not as strong as laying bricks at an angle and pressing cement tightly like the technicians usually do. And if the materials are not chosen well. In the future there may be a problem from the collapse of the materials. When the wall collapses, it will follow with cracks.
