If your plans include the demolition of an old building in order to free up precious space for the start of new construction, the reconstruction of a building or a simple redevelopment, then sooner or later you will face the task of finding a quality floor dismantling service. In addition, such a service may be needed by those who are interested in improving the appearance of the facade of their house or creating new ventilation in the premises.
Dismantling floor slabs is an extremely time-consuming and technologically complex process that must be carried out exclusively by specialists in their field. That is, it is certainly not worth dismantling heavy and bulky floors with your own hands. Moreover, it is advisable to perform this procedure with the appropriate inventory and equipment. But for those who nevertheless decided to do the dismantling of floor slabs on their own or want to carefully control hired workers, it will be interesting to know how to do this work correctly.
Preparation for dismantling
Before proceeding with the dismantling of the ceiling, you must firstdisassemble plumbing, eliminate wiring, flooring. Then, existing lintels and walls should be repaired, as well as openings that will not be used in the future should be sealed. In parallel with these actions, it is necessary to carry out an examination of the general condition of the floor:
- place the floor structure to determine the sequence and methods of future work;
- assess the level of wear to identify weaknesses and temporarily strengthen or protect them;
- determine the reliability of the lower floors for the possibility of collapse of the upper slabs or the installation of special supports;
- examine the places of installation of temporary coating and storage of dismantled materials.
It is impossible under any circumstances to dismantle floors on several floors at the same time.
Dismantling the ceiling on wooden beams
Such work involves the removal of backfill, dismantling of rolls, filing of beams and ceiling. Backfill, and in the attic - pre-loosened coating, must be collected in containers and lowered using a tower crane. If you don’t have a tower crane in your arsenal, you can use inclined trays to lower materials, having moistened them in advance. Rebounds can be disassembled with a crowbar, simply tearing off the boards from the bars. The lining of the ceiling structure should also be dismantled with a crowbar, and the torn boards can be dropped to the lower floor or leaned on partitions.
Floor beams, which can be used in the future, are disassembled differently:
- first of all under the barsit is necessary to bring temporary supports;
- then you should release the edges of the beams, thus increasing the gaps and carefully bending the metal fasteners;
- after which the beam must be brought to a special stage and sawed off one of its edges;
- then both parts of the beam must be lowered to the lower tier and taken out through the window openings.
Builders who have a tower crane at their disposal can dismantle floors in blocks of 2-4 beams, filing or rolling. The block is formed by freeing all its elements from fasteners and nearby parts of the building. Slinging can be done using a special traverse or a sling.
Dismantling of wooden floors on iron beams
This type of dismantling is done in exactly the same way as dismantling the ceiling on wooden beams. The dismantling of such a ceiling differs exclusively in the removal of iron beams. To do this, it is necessary to place scaffolds along the load-bearing partitions and free the edges of the beams, horizontally punching grooves in the walls. After that, the beams must be pulled out of the nests by turning them in horizontal grooves. You can remove the removed beams either with a tower crane or manually through window openings. Ceilings on metal beams cannot be dismantled in large blocks.
Dismantling of brick and concrete floors
The dismantling of floors from concrete or brick vaults along iron beams is carried out in the following order: backfill removal, base dismantling, removal of beams. Taking into account certain factors, the vaults should be dismantled either transversely or longitudinally.
The longitudinal dismantling scheme means the installation of appropriate spacers along the length of the beams. For such work, spacers made of timber or logs with a diameter of 140-180 mm are suitable. Spacers are placed at intervals of 2-3 m along the bottom of the beams on the same line, perpendicular to the axes in the furrows, which must first be done in the vaults. Only after the correct placement of suitable spacers can the direct dismantling of the ceiling begin.
The transverse scheme of work involves the placement of spacers with an interval of 1.5-2 m. In this case, temporary fixators are not installed. Walking bridges should be placed along the floor beams, along which builders move.
Dismantling the monolithic ceiling
Before starting this work, first of all, it is necessary to determine the exact design of the floor to be removed, the direction of the span of the slabs, as well as the placement of the main and secondary beams. In this case, it should be noted that the base is first disassembled and only then - the beams. Under no circumstances should this rule be ignored. Otherwise, the ceiling will simply collapse on the lower floor.
Cost
Prices for the dismantling of the ceiling depend primarily on its type, its area and general condition. Consider an example. The cost of dismantling a dilapidated wooden flooris only 500 rubles, but the price of removing a concrete or iron structure can reach 2,000 rubles. But even if it seems to you that the cost of dismantling is high, do not try to take on this procedure yourself. Remember that this is a very difficult task that is extremely difficult to complete without special equipment, tools and, of course, skills.
