What Are The Boards In Construction?

If what you want to achieve is an excellent finish so that the result of your construction is of quality you cannot ignore the use of the joints, so if you are on the ground there are some things that you have forgotten, do not worry, because in the next post we will remind you, likewise do not forget to read our other available articles so that you are the best architect or mason of the work.

Joint Function

The joints are separations or openings that are made in rigid structures to give them ease of movement and flexibility, avoiding eventual fragmentation that they could have.

Types Of Joints In Concrete

Within the joints that can be made in concrete to prevent cracking are four types:

  • Shrinkage joint: It is effortless that cracks appear at points of weakness due to the contraction of concrete, or due to Coarse sand (ทรายหยาบ ,which is the term in Thai) that is why these joints are deliberately made, which are cuts in the concrete, since if this is going to crack, it will along with the geometric pattern drawn, avoiding irregular cracks. Shrink joints are mainly used in pavements, walls, floors, and ceilings.
  • Expansion joints: They are used before the possibility of concrete cracking due to dimensional thermal changes. They are placed where there are sudden changes in thickness or changes in the type of construction.
  • Insulation joints: This type of fittings is characterized by allowing independent vertical and horizontal movements, even decreasing the possibility of cracking when movements are minimal. Insulation joints can be made circular or square.
  • Construction joints: These joints will serve you to achieve continuity of the reinforcement and adhesion. In most cases, you will find them on surfaces with two concrete drains. They are designed for transferring loads or allowing mobility, and they tend to be done at the end of the workday, although they can also be done when concrete emptying is paralyzed.
