During the construction of a concrete structure, it is possible that for various reasons, including modification or changes in the executive plan or the need to expand the concrete structure during operation, it is necessary to use rebars of different sizes in the existing concrete. Therefore, strengthening and planting rebar or reinforcement is one of the methods of strengthening and strengthening concrete structures using FRP fibers, which provide us with the possibility to easily make the changes that have been made in the executive plans or Implement retrofit plans. By using rebar planting method, this capability is created to connect new concrete to old and connect steel components and structures to existing concrete structures.
Reinforce Reinforcement and Planting 🔰
Normally, when the implementation of a concrete structure is done, reinforcement is done first and then concreting is done, but after concreting the concrete structure, if we decide to make a change in the construction, doing this The work has its own special engineering solutions, for example, after concreting the foundation, the roots of the columns' reinforcements are implemented, and if we decide to increase the number of reinforcements, normally, the entire foundation around the columns must be destroyed and the reinforcement of the column's roots is done again. This work, in addition to the cost and time it spends, weakens the foundation. In the new engineering methods, to prevent the destruction of the foundation, the method of strengthening and planting rebar is suggested. In rebar planting, concrete is not destroyed, but according to the type of rebar, holes are made in the concrete and new reinforcement is installed or planted. The diameter and depth of the hole created in the concrete is proportional to the diameter of the rebar. The type of glue that is used in planting rebars, as well as its usage date, must be approved by the monitoring body before implementation.
What is the purpose of rebar implantation? 🔰
In construction projects, it is sometimes possible that due to changes in the executive plan and the need to move columns, rebar planting is necessary, so rebar planting is used to strengthen and strengthen civil structures, as well as to add new structural components. It is done to the existing structure. The purpose of planting rebar in concrete can be one of the following: - Connecting a new structural element to an existing column - Planting a rebar in a column to implement a staircase fence - Connecting a concrete beam in an existing column - Extending a column in the direction of an existing column - Adding The console in the building. Also, among the non-structural applications of planting rebar in concrete, we can also mention the installation of equipment and utility hangers to the existing concrete elements.
What is a rebar planting adhesive? 🔰
Reinforcement and bolt planting glue is a type of two-component glue based on epoxy resin, polyester or vinyl ester, the other component of which is a hardener based on polyamine. Usually, this product is used to install reinforcement and bolts. Normally, these adhesives are available in the market in the form of cartridges, which are uniaxial if the second component is inside the compartment of the first component, and if the compartment of the two components is separated from each other, They are called biaxial.
Benefits of Rebelling Planting Method 🔰
With the introduction of rebar planting method, other strengthening methods have become less important; Because rebar planting has many advantages. For example, these advantages can be mentioned:
🔰 The dimensions of the foundations are changed by using the rebar planting method in the inner and outer walls of the foundation.
🔰 With the help of the planting method The rebar of individual foundations is converted into a strip and a wide strip.
🔰 With the help of rebar planting, new walls can be built and the building can be expanded.
🔰 Rebar planting can be done in large commercial complexes. and stabilized the mechanical facilities.
🔰 With the help of the rebar planting method, it is possible to build handrails and develop cantilever beams. construction.
🔰 In structures like villas, rebar can be used at the floor level and new concrete consoles can be created. It is possible with the help of planting rebar, because this method increases the number of floors in buildings.
🔰 Rebar planting can be used to strengthen the columns. Old or half-built concrete walls are developed with the help of planting rebar.
