What is the Wall Post?
Wall post is a low-grade, coil-shaped profile that is placed in certain lengths to make the wall work seamlessly between the frames and inside the wall. In fact, the wall posts transfer the incoming forces from the wall to the frame during earthquakes and wind, and as a result, they make the wall stronger. As mentioned, wall post is used to better connect the wall with the frame of the structure, and in the dictionary it also means "wall holder".
The importance of using a wallpaper
Most activists in the field of construction believe that the strength of the main parts of the structure such as beams, columns and roofs is enough for the strength of the building and its proper functioning. In recent earthquakes, especially the Kermanshah earthquake, it was seen that despite the stability of the structure and its main members, the lack of strength of the non-structural members, such as the surrounding walls, blades, facades of buildings and facilities, can cause irreparable economic damage and even loss of life; Therefore, the need to implement sections such as Wall Post was made clear to everyone.
Types of Wall Post
Types of wall posts are in two general categories:
1- Vertical or upright wall post
2- Horizontal post wall
Vertical Post or Vertical Post
The vertical post wall is used when the opening is large, and to install it, it is welded from the beam of the lower floor to the beam of the upper floor in the opening. In the implementation of the vertical post wall, grade 10 ribbed rebar should be welded to the corner or can at intervals of one meter to one meter to create the necessary contact between the blade and the post wall. In this case, the wall will have a more uniform behavior when the lateral loads are introduced.
In addition to the angle used in the wall post, all profiles or rebar used in the construction and completion of the wall post should be stainless steel or completely covered with primer. to be If the profile you considered is for a corner post wall, it is better to consider its opening one centimeter more than the thickness of the corresponding wall.
Horizontal Post
The horizontal post wall will be applicable only if the height of the wall is more than 3.5 meters. For a better connection, the horizontal post wall is connected to the roof structure using ribbed bars of grade 14 or higher at intervals of 1 to 1.5 meters.
The most important applications of Wall Post with corners in different structures
Wall posts are used in various structures, including metal and concrete structures, and a special type of wall post is designed for each structure. goes Wall post in different structures are made from profiles such as corner, stud, can and belt; But the wall post made from a corner performs better in transferring the lateral load and uniformity of the wall than the type produced from the profile can.
How to run and detail the performance of the Post Post
There are 2 ways to implement wall post in buildings:
The first method
In the first method of implementing wall post, it should be done before concreting and when reinforcing the plates. be placed inside the section.
Second method
In the second method of wall post execution, after concreting the sections, the desired plates should be fixed on the concrete surface by anchor bolts.
Run the Wall Post in Concrete Building:
Execution of wall post in concrete building is very important; Because the use of wall posts prevents the structure from changing its shape during an earthquake.
Run the Wall Post on the steel skeleton:
It is necessary to implement the wall post in the metal frame; Because due to the relatively large lateral location change of the structure, especially on the higher floors, it can help the correct functioning of the structure. The method of welding wall post to buildings with a metal frame is done by welding wall post to beams and columns.
