Kinds of floor sections

Kinds of floor sections, unidirectional chunks, pieces (τσιμεντοκονια)

The chunks are generally made of concrete, despite the fact that they can likewise be used in clay or porexpan, with which we can help much more the heaviness of the floor. 

Clearly every one of these elements, before winding up some portion of the structure previously concreted, need to go depending on the manufactured formwork to have the option to be gathered . The formwork can be full board or can be halfway formwork, in which just the regions of the bars are encofran where the leaders of the joists lay and on these the vaults rest. 

These incomplete formworks spare a ton of formwork wood, yet they require working from the lower floor with assistant methods until a help surface is shaped, which should likewise be ensured to avert falls between the joists. 

Kinds of floors, unidirectional, halfway formwork. 

As I said toward the start, it is a kind of produced very normal, however it has a few downsides. One of the principle downsides of the unidirectional sections of joists and vaults is that they require a huge stockpiling zone. The joists possess much, the vaults additionally, the equipped ones, the wood of formwork, the props ... they require to have arranged the space where it will accumulate every one of these materials in the work . 

Also, another disadvantage is that they are exceptionally overwhelming materials, so they need helper intends to assume them to their position of placement since it isn't suitable to be transferred to the relating plant by hand by the administrators. Because of a topic of times, however of security. 

Furthermore, this weight influences the heaviness of the floor itself , so the structure as of now needs some protection from hold itself, affecting on the measure of concrete and steel you will require by estimation. 

Another downside is the absence of adaptability with the geometry of the floors of the structure . The joists can not be cut in situ at our impulse, so if there should arise an occurrence of complex geometries wherein the pillars are not parallel, you would need to request joists with various sizes to go adjusting its length to the geometry of the floor. 

Unidirectional producing of joists in situ 

This would be a variation of the past kind of prestressed joist manufacturing. In this sort the working arrangement of the chunk is the equivalent, just that as opposed to utilizing pre-focused on shafts , these joists are gathered in situ during the get together of the section . 

Sorts of floors, unidirectional, fashioned joists in situ 

This is an incredible favorable position for floors with complex geometries , since the elements of every one of the joists can be changed in accordance with the centimeter, despite the fact that it requires a progressively cautious execution, since the principle safe element isn't prefabricated , yet it might endure execution disappointments during the procedure. 

Notwithstanding not being a prefabricated element, the strengthening reinforcement isn't prestressed, so it has less opposition , which must be considered in the count of the structure. 

Another factor to be considered is that, being joists executed nearby, it requires more prominent consideration in the execution , both the placement of its gathering elements, regarding position, quantity and coatings, as in the concrete itself, which must be vibrated with more consideration if conceivable to guarantee an excellent concrete that opposes accurately the heaps it needs to help and, most importantly, with the durability that is required.(γεμισματα δαπεδων)
