Balconies are almost unheard of in the new homes being built today. Such instances are very rare if the owner is not anxious to build a balcony for every room built upstairs whenever possible. It adds some elegance to the building and is a great place for residents to see the beauty of the surroundings.
The purpose of this article is to provide relief to those who do not have a balcony for their new house, and who have the same desire, or who have purchased an old house or newly built house, hoping to build a balcony where they want, but are unable to do so. Also, if you are an owner who is remodeling an old building and looking to build a new balcony, reading this article will help you to fulfill that desire.
You may not have an estimate of the size of the balcony you want. Although the subsequent construction of such a balcony was a risky and challenging task, today it is possible to successfully meet that challenge using the latest technologies in civil engineering. The Civil Engineer is in front of you in this heavy task. It is important to keep in mind that you should take the next step in that risky endeavor on the full advice of a civil engineer.
This is because when a new balcony is introduced to a finished building, deep civil engineering matters have to be used to determine its thickness and the amount of reinforcement wire required. Therefore it is extremely important to always do it on the advice of a civil engineer in such a case.
Construction of such a balcony would not be a serious or challenging task if the building included a balcony at the time of design. But when a new balcony is introduced to the old floor, it is necessary to use the techniques introduced to the world with the advancement of modern technology.
However, it is worthwhile to first gain an understanding of how to build a balcony according to the traditional methods we are familiar with. One method is to attach several layers of iron frame to the wall and make a layer of wood or concrete on top of it. This method is unique in that it can be done without damaging the existing concrete floor. However, the iron frame floors have retainers for wall mounting.
Anchor Bolts can be used for this, but it is important to make sure they are adequate in advance. Or you can use nails of sufficient length to be drilled into the walls.
But it is difficult to imagine a homeowner satisfied with the exterior decoration of a balcony finished this way. This is because a balcony with frame frames cannot be as beautiful as it looks. It is not the purpose of this article, however, to make such an introduction.
The second method is to build the balcony as a new concrete floor. In this case, the reinforcement wire to be applied to the proposed balcony is to be inserted to a specified distance on the old floor, ie anchorage length. This can be done by breaking down the old concrete floor to the required distance and connecting the new wire with the old wire and concreting the balcony floor and the demolished parts of the old floor together.
DThe advantages and disadvantages of this method are as follows. If the building is currently in use, the concrete will have difficulty breaking. It is also a risky activity. This is because props must be applied at will to balance the concrete floor during breakage. Also, if there is a wall in the area where the balcony is proposed to be installed, it should be demolished.
In such cases, some masons, without consulting any civil engineer, weld the newly added reinforcements to the raised reinforcement wires to reduce the demolition of the old concrete floor. But this is a very risky operation and it contradicts the principles of civil engineering. This is because when welding the steel wire (tor-steel) we use for concrete, its quality decreases and it fails to achieve the expected tensile strength.
But here we can successfully construct a new balcony using the latest technology. This should be done under the supervision of a civil engineer. The below figure shows how the beam is perforated and reinforcements are inserted into the beam. These reinforcements are pasted into the drilled holes with chemical anchoring.
Determine the weight of the new balcony to be added and other external forces (human weight, handrail or safety barriers, etc.) (seek the services of a Chartered Civil Engineer) and determine the required balcony thickness and the size of the reinforcements. The Civil Engineer then calculates the embedding length of the new reinforcements to support the load, depending on the bonding stress of the chemical.
