Stages of work

Initially, it is necessary to properly prepare for the destruction of an unnecessary structure. The preparation process is quite labor-intensive and consists of the following sequential actions:

• 
  Installation of equipment and crumbling of concrete.
  The first step is to study the site where dismantling is planned.

• Next, you should discuss all the nuances of the work.
• All communications, if any, are turned off.
• The entrance to the facility is being prepared, as well as a free area for the delivered special equipment.
• Then this equipment is installed directly at the site of future work.
• Next comes the process of dismantling concrete structures. Various coverings are removed, the monolithic structure crumbles.
• Upon completion of work, the area should be cleaned. The dismantled pieces are calibrated, loaded into prepared transport, and taken away.

It is very important to consider issues such as safety. To do this, it is necessary to organize the stability of the structure during its collapse, so that there is no premature, unexpected collapse, due to which people may suffer. Based on this, only knowledgeable, experienced craftsmen should be involved in the work.

Dismantling reinforced concrete fences

Dismantling a reinforced concrete fence is a frequent operation; it is required when clearing areas after industrial workshops, enterprises, and warehouses. Such work is usually carried out in several stages. First, the reinforcement is disconnected from the concrete parts; an ordinary grinder or welding machine helps with this. Using a truck crane, reinforced concrete and monolithic panels and glasses are dismantled, which are loaded onto special powerful equipment, which is designed for the removal of such structures and is designed for their weight and volume. After this, the remains of the fence are removed and the area is cleared of debris. If fence removal is done professionally, some slabs and fence posts may be reusable.

Advice from experienced professionals

• Carrying out dismantling work that requires the use of impact devices is a very expensive service, since these devices negatively affect human health.
• Dismantling work is always accompanied by the appearance of dust and debris. Therefore, you need to worry about transport for waste disposal in advance.
• It is not recommended to carry out dismantling work yourself without special skills and knowledge, as you can not only harm the entire structure of the structure, but also your health.
• During work, do not neglect protective equipment. Be sure to wear a helmet, respiratory mask, special glasses, and headphones. Because the work ahead is dusty, noisy, and quite dangerous.

Dismantling brick walls (manually)

Dismantling and dismantling of brick walls is done manually in cases where it is necessary to preserve bricks for reuse, or when creating openings and dismantling brick partitions indoors. For manual dismantling of brickwork, a hammer or sledgehammer is used as auxiliary tools. This is a rather labor-intensive method that requires time and human resources.

Workers begin to dismantle the brickwork from top to bottom, carefully beating the bricks with a hammer, sledgehammer and other tools. Some have to be cleaned of old cement mortar.

If large volumes of brickwork need to be dismantled, a combined dismantling method is most often used, which involves the use of manual labor along with the participation of special equipment. This is complex, time-consuming work, so in order to avoid unforeseen cases, it is best to turn to professionals.

What tools, equipment and protective equipment will be required?

Before starting work, the master must draw up a work plan and a list of necessary tools, equipment and machinery. With the wrong approach and choice of equipment, irreparable harm can be caused to the facility and people’s lives.

Depending on the types of floors, the following tools and devices may be needed:

• 
  jackhammer;

• sledgehammer;
• scrap;
• perforator;
• gas or electric cutter;
• Bulgarian;
• jack;
• supports of various types;
• wooden beams;
• device for diamond cutting;
• crushing bucket;
• hydraulic cushions.

To remove debris from the site, you will need a lift, winches and a truck.

Dismantling of staircases

Before the difficult process of dismantling staircases, it is necessary to conduct an inspection of their technical condition. The sequence and method of the planned work, the possibility of a flight of stairs collapsing, as well as a place for storing disassembled parts of the stairs and debris must be determined.

Dismantling of staircases is carried out gradually, from top to bottom, floor by floor. Simultaneous work on several floors is not permitted. Exits from the interior to the stairs must be blocked, and the work must be carried out using temporary flooring.

Dismantling of staircases made of reinforced concrete products begins with determining their structure, reinforcement scheme, and technical condition. The reinforcement that creates strength and stability must be highlighted. The process of dismantling the marches must be carried out by qualified workers in compliance with all safety standards and technology for the dismantling process.

What are the features of concrete cutting technology?

Experts are well aware that solid concrete is quite difficult to process using mechanical cutting or drilling. It will take a lot of effort and a lot of time. Even recently poured concrete structures can be dealt with, but after several years the concrete becomes a durable monolith that will have to be worked on.

This is due to the following reasons:

1. Over time, concrete grains acquire high abrasive and abrasive properties. When trying to cut concrete, any metal literally loses the sharpness of the cutting surface in a matter of minutes. In this case, cutting concrete quickly will not work. It will take a lot of time.
2. High level of strength of sand or gravel fillers. This is more typical for heavy grades of concrete.
3. The presence in the body of concrete of metal reinforcing elements used to create a frame.

Only diamond cutting made it possible to quickly and efficiently cut any of the most durable concrete. Made it possible to significantly reduce the labor intensity of operations. High quality cutting geometry is achieved, which is used in creating window and door openings.

Step-by-step instructions on how to dismantle

Dismantling the floor slabs of an existing building is considered a rather difficult task. When dismantling various types of structures, you have to follow certain rules and regulations .

In order to choose the most effective and safe method of dismantling, before starting work, the structure is inspected, assessing the degree of wear of the slabs. Communications are removed even before dismantling work begins. They dismantle the floor coverings and prepare a place for the falling fragments of slabs.

Wooden structures

Stages of work:

1. The backfill, boards, and running boards are removed.
2. The roll-ups are being sorted out.
3. With the help of the house, the beam and ceiling lining is dismantled.
4. The beams are removed.
5. Supports are installed on the sides.

If the beams are intended to be reused, then the work is carried out in the following order:

• temporary supports are secured under the beams;
• the edges of the beams are released, widening the gap and bending the metal fasteners;
• the beam is brought out onto the installed scaffolding and one of its edges is sawed off;
• parts of the beam are lowered to the lower floor and carried out through the window openings.

Concrete

Stages of work:

1. The cement screed is destroyed and removed.
2. Grooves 30 cm wide are cut.
3. Using a jackhammer, fragments of cement are broken off.
4. Find out the location of the reinforcement inside the slab and its direction.
5. Using a jackhammer, destroy the slab as the reinforcement is laid in strips 40 cm wide.
6. Reinforcing bars are cut using a cutter.

Next, the load-bearing beams are disassembled:

• secure the supports;
• break slabs;
• cut the reinforcement frame.

Concrete and brick

Stages of work:

1. The backfill is removed.
2. The base is disassembled.
3. Beams are removed.

Such floors are dismantled using the transverse or longitudinal method. Spacers are installed at a distance of 1.5-2 m. The vault is destroyed in parts 2 m long. With the longitudinal method, spacers from beams 18 cm thick are installed from below the beams at a distance of 3 m from each other. They will take on the load of the adjacent vaults.

Void

Dismantling of hollow core slabs is carried out entirely, using a truck crane or other lifting equipment . If the use of lifting machines is not possible, then dismantling is carried out manually, which involves the mandatory installation of formwork or frame scaffolding under the slabs. The slabs are cut into lifting pieces with a jackhammer or circular saw.

Monolithic

Using a jackhammer or concrete breaker with this method is considered the most economical dismantling of a monolithic floor.
The reinforcement is cut with a cutter or grinder . But with this method there is a risk of destruction of the object due to high vibration due to the operation of fendering equipment.

Vibration load can be minimized by using diamond cutting. In this case, not only will communications be preserved, but there will be less dust and the time required to complete the work will be reduced.

Often the dismantling of monolithic floors will be carried out in a mixed way, using different tools. A diamond tool is used to cut along the perimeter by 2/3 of the thickness of the ceiling. The internal parts are destroyed using a jackhammer or concrete breaker.

How is the estimate prepared and what indicators are taken into account?

One of the most difficult types of work is the dismantling of floor slabs of a working building. When dismantling, builders have to work with different types of structures, and they all require compliance with certain rules and regulations.

Before drawing up an estimate, specialists examine the structure and especially the floor slabs, assess the degree of wear, and choose a safe and effective method of dismantling work. All this information and the plan for dismantling work are entered into the technological map and an estimate is drawn up.

Possible difficulties and errors during the disassembly process

Before you begin dismantling the floor slabs, you should make sure that the material does not collapse on the lower floors . To do this, the dismantled parts must be supported using a crane or winch.

If there is a threat of slab crumbling, the part to be removed should be strengthened with anchors, nets, staples, or a protective coating should be laid on the lower objects. Fragments of a large area are divided into parts and removed through window openings.

It must be remembered that all work must be carried out according to the project , so as not to disturb the solidity of the supporting structures, thereby avoiding the collapse of the structure. Before starting work on dismantling the floors, you should take care of cargo transport for removing garbage and waste.

During dismantling, workers must wear special clothing, safety helmets, goggles and gloves. And when working with a noisy instrument, use special headphones.
