Waffle roof slab

The waffle roof is said to be latticework and pillow ceilings, which are used to cover wide openings. The function of this type of roof is a two-sided slab, and there is no need for reinforcing bars and joints to beams. The mold of this type of roof is cubic and empty, and is used in different dimensions depending on the project. Waffle molds are made of composite plastic and lightweight so that they are easy to carry by the workers. The waffle roof is suitable for all kinds of metal and concrete skeletons. The molds of this type of roof allow the roof to be mounted in a one-way or two-way slab by changing the assembly.
The waffle roof is a slab roof, which is used to render it instead of flat and flat molded slabs, using molds, which are sometimes referred to as “shapely shapes” or rectangles. These two molds are made from concrete underneath the roof, forming the joists. These types of ceilings are the ceiling of a grenade or a waffle.
Depending on the shape of the shapes, they are rectangular or square. On the ceiling there is formed a one-way groove, bearing in one direction, formed for rectangular molds, and the formation of double-sided or bearing arches on both sides (in 2 steps) for square shapes. These ceilings are unilateral waffles and double waffles respectively.

Waffle template feature

Waffle molds after concrete concreting operations can be separated from concrete and can be used again in other construction projects. One of the features of these types of molds is their refinement, which can be recycled after the useful life of the templates has expired. The use of these composite molds increases the durability and toughness of the ceiling and makes the structure lightweight, which makes the building more safe from natural disasters like earthquakes. These templates make it possible to remove roof blocks from the building, which is why the structure is lightweight.

Infrastructure methods:

The construction of the waffle roofs is roughly similar to the Pebble Ceilings and can be used with conventional appliances in construction workshops, such as wood and quartz, metal cans, scaffolding tubes and other similar appliances for its construction.

Run inside the joist

Due to the special design of the mold, the joist is implemented locally. With this method, all the problems of making the joist and carrying it are also eliminated. Due to the limitations in the design of the joists, this can be done by removing double beams. This causes the weight of the ceiling to be reduced to 79 kg / m2 due to weight loss. It can be applied to any length (for example, 12 cm) at the waffle roof. This will help the construction of the structure.

Another advantage of the on-site joinery is the absence of a need to move the crumb in the main beams when closing the armature joist. Concrete joints and roof rigidity are in good agreement with the joists. This reduces the shaking of the roof during operation. Also, precise monitoring and control of the size of the armature and its arrangement before the concrete is done.

Template layout

The waffle roof is available in a variety of concrete and metal skeletons. It is also possible to change the mounting method of the mold, using a one-way or two-sided slab. The point to be made is that the molds are assembled with bolts and nuts, according to different openings, to the desired size. At the end of the mold, the pieces are closed as a cap. At the time of separating the mold or carrying it, no need to open the bolts.

In the work, the mold is seamless and portable in various lengths. In this way, the strings and the secret (hidden) are executed accurately. Also, because of the strength of the mold, it is easy to navigate through the mold. This formulation does not need to be greasy to separate, and because of its kind it can be ensured by the time of opening the mold from the curing of concrete.

Ability to pass the facility:

Due to the shape of the ceiling (hollow slab), the space available under the roof can be created by observing the regulations of the premises for the passage of the facility. By passing the facility from below the ceiling, it helps to reduce dead weight and also the weight of the flooring. In addition, an increase in useful height and comfortable repair of the facility at the time of operation also affects.

A summary of the advantages of the waffle hollow slab system:

Saving on weight and materials
Long distance
Appearance Appealing
Reusable
Vertical intersection between gears is easy.
Flexible
Build speed
Volume of heat
No need for double arches in openings more than 7 meters
Slim depth
Strength
Excellent vibration control
Resistant to fire
The need for burying parts in concrete that is costly and non-economic are the view of the blocks used in other hollow slab systems (Yubut and Kobyx).
No need for lubrication (Concrete does not stick to the mold surface, therefore the concrete surface provides a very good view).
Acoustic (absorbent and dampening) This type of roof structure is suitable for crowded congresses and crowded and crowded environments.
Lower consumption of concrete and reinforcement due to structural weight loss and consequently a significant reduction in operating costs compared with other similar methods
