Overhaul work begins with dismantling as part of the redevelopment of housing. The most difficult and crucial stage is the analysis of the supporting and main partitions, which is characterized by high labor input and financial cost. Nevertheless, it is possible to realize the dismantling of walls and partitions on their own, having previously obtained the appropriate permission.
Dismantling preparation
Before proceeding with direct work operations, it is necessary to coordinate documents confirming the dismantling process. As a basis for redevelopment, in particular, an inventory plan with the results of a building survey can be used. On its basis, a draft layout of the premises is drawn up, which is approved by a special commission in the local city-planning authority. The permits for the dismantling of walls and partitions in the apartment should describe the technology of the work, the conditions for their implementation, schemes for the future location of utilities, ways of delivering equipment with materials and removal of construction waste. When the relevant documents are completed, a technical and instrumental base for the implementation of the project should be prepared. Again, if you plan to carry out dismantling without the participation of specialists, then at least you need a hammer drill (even better - a jackhammer), a hammer with a sledgehammer, a chisel, metal wedges and a crowbar with a pickaxe.
Stages of dismantling activities
The entire process of the main part of the work can be divided into three stages:
- Dismantling of structures by mechanical separation of their basic bearing parts from each other. Separated elements are removed, after which they are sorted and stacked. At this stage, the technical destruction and loosening of stone, brick and concrete structures is carried out.
- After dismantling the walls and partitions, preparation of construction waste and equipment is carried out. Materials are being loaded and transported to a landfill or to special collection points for secondary use.
- The site is being prepared to carry out already new construction and installation activities.
Diagrams of dismantling walls and partitions
In the case of stone and reinforced metal-concrete structures, two different approaches to dismantling can be applied:
- A destruction scheme is provided in which the force is directed from top to bottom. This option is used in cases of dismantling structures in private houses with several floors. Activities begin with the elimination of attic walls, and end with the demolition of the basement walls (if necessary).
- The most common scheme of partial dismantling of walls and partitions, in which it is possible to use manual force without special equipment. This approach is used in cases where it is necessary to eliminate one or two structures without a comprehensive review of the layout.
Dismantling brick walls
If the doorway is present at the base of the structure, it must be dismantled first together with the duct. Further work continues in the direction from the opening to the sides and up. The technique of dismantling brick walls and partitions involves alternately knocking out masonry levels. Usually, a sledgehammer with a hammer and a chisel is used for this, and in difficult areas you can connect drilling operations with the same hammer drill with impact action, which will lead to cracking and simplify further work.
Dismantling the partitions
Unlike walls, partitions are characterized by a weaker structure, a less reliable support part and connection nodes. If we are talking about drywall or, in principle, modular partitions, then work should begin with twisting and removing the hardware on which the supporting profile strips are held. In theory, they should be on the ceiling, in the floor and on the sides. If there is a question about how to disassemble a wall fastened with a partition, events also begin with a weaker part. Having removed the supporting and supporting parts, it is possible to disassemble the base of the partition without a special tool. If we are talking about monolithic structures, then the optimal solution would be to use a large drill for concrete. With its help, clipping contours of individual fragments of the partition are formed, after which a sledgehammer with a hammer is introduced into the working process.
Garbage removal
Even at the preparation stage, it is advisable to conclude an agreement with a specialized company offering services for the removal of construction waste and stipulate specific dates. Immediately after the completion of work activities, the sorted material is placed in a special container. For direct removal, bags for construction waste from high-pressure polyethylene 55-65 microns thick are used. To collect large waste, it is worth preparing bags with a capacity of about 350 liters. For small but sharp and cutting materials, woven bags made of polypropylene up to 80 liters are designed. Then it remains to take out the trash and put it in the vehicle.
Conclusion
Dismantling measures are not easy to carry out without the help of special equipment and professional builders, especially if such a task is solved for the first time. And yet, subject to a carefully thought-out plan with a detailed description of each stage and preparation of a sufficient set of tools, it is quite possible to implement redevelopment on your own. In this case, and the cost of this event will cost inexpensively. For example, construction waste bags as a consumable will cost about 1000 rubles. This is based on the fact that two packs of 350-liter bags of 10 pieces are used. As for the tool, it will cost more - about 4-5 thousand rubles. for a punch, for example. A chisel and a hammer with other tools are cheaper to purchase in a single set, which will also cost several thousand rubles. The company's garbage collection services are estimated at 1000 rubles on average. per 1 m 3 of waste, taking into account the fact that the employees of the hired organization will carry out loading and unloading activities.
