What is the Wall Post and how does it run?
In the construction process, when the walls are long or long, they may bend or fall due to the forces from the earthquake or high pressure. To prevent this from happening, wall posts (steel sheets bent into a U shape or studs) are used, which are placed vertically in the wall to make it stronger and more resistant. The horizontal (bed rebar) that is attached to the wall prevents the walls from being damaged in an earthquake or strong wind, and has made the walls safer in harsh conditions.
What is the purpose of implementation and task of the Wall Post?
The purpose of implementing wall posts in structures is to transfer the loads resulting from earthquakes, etc. to the frames of the structure and to secure the walls. Wall posts are classified into vertical and horizontal categories. Their vertical type is implemented in the vertical direction of the structure and parallel to the columns, and they have a significant effect in bearing vertical loads, and their horizontal type are installed perpendicular to the columns and bear the horizontal loads of the building. In earthquake-prone areas, they use a combined wall post to increase the safety of the structure. This means that the implementation of the wall post with the bed rebar is done in two vertical and horizontal ways. The production of horizontal bed rebar is done by coiled rebar with a diameter of 4 mm.
How to implement and run the wall
For the implementation of wall posts, they use profiles such as studs, cans, corners, etc. If the wall post is produced from a corner, compared to products made with cans, it shows better performance in terms of integrity and transfer of load to the wall, which will be examined in the following steps of implementing this method in structures:
< b>Determining the position: First, you need to determine the position of the wall post based on the map.
Executing the connection plates:Next, after installing the connection plates On the floor and ceiling, use fasteners to line up the blocks so that two separate walls are connected to each other.
Base plate installation: If you do not install the base plate before pouring concrete, You need to attach the plates to the beams from above and below by roll bolts.
Installation of steel nails: Use 3 cm steel nails applied with a nailer to implement the plates. Beams are not a suitable choice.
Rebar packing:After building the wall, weld four rebars to the connected plates embedded in the floor and ceiling, and in the next step, tie them with reinforcing wire. Attach to the fasteners.
Pouring the concrete: In the last step, after installing the rebars, pour the concrete into the forms.
Opening the forms : After pouring the concrete, open the molds so that the post wall is installed in the concrete frame according to the thickness of the wall.
It should be noted that if any of the provisions of the National Building Law are not implemented, it will result in many financial and human losses. In addition, if the building is destroyed due to an earthquake or wind and it is determined that there has been negligence in the implementation of these regulations during the design and construction; One of the main culprits is the supervising engineer of the building.
Connecting the wall to the column in the wall post: One of the cases of implementing the wall post is in the connection of non-panel walls to vertical components such as columns.
Connecting the wall to Under the beam or ceiling in the post wall: In this case, the wall should not be connected to the beam or ceiling in any way. For this purpose, the wall should be separated from under the beam by using corners that control the movement outside the plane of the wall and separating materials such as unolite and stone wool. Note that the corner or studs can be connected to the beam or ceiling using welding, screwing, or using epoxy glue. The upright metal acts as a main support for the wall. The length limits of the wall can be solved by using fasteners. The connection of this type of wall posts on the floor should be of the girder type and under the roof or beam should be of the joint type (telescopic connections) so that the force changes its shape during seismic vibrations and repels the force of the earthquake.
Types of Wall Post
According to the needs and conditions, the wall posts can be implemented at the connection to the column, beam or ceiling and in this way, provide the possibility of free movement of the intermediate frame components. Getting to know the types of wall post connection methods can help you choose the right wall post.
