Flat Fix spacer has two prongs for locking of rebar inside. The rebar is mounted on Hard Fix Spacer seat and fixed by locking prongs. The distance of rebar seat up to the bottom of frame or surface is determinant of concrete cover on rebar. There is also a flat sheet on horizontal mode below the Flat Fix Spacer which should be placed on the surface completely in horizontal form in order to prevent from interfere and/or insertion of spacer into the recessed surfaces.
 
On soft & recessed surfaces:
The consumption rate is 4pcs in one square meter.
 
On Styrofoam surfaces:
The consumption rate is 2 pcs in width of foam which should be repeated in a distance of 50cm from each other on the length of foam.

Qty & Consumption method:

One of most concens of dear performers is rebar on soft & recessed surfaces, such as Styrofoam roofs. This is because the applied spacers in these surfaces will be inserted in current soft & recessed surface due to the movements of personnel and transfer of building materials and concreting. Then it is impossible to have an integrated rebar network. This is necessary to mention that generally thermal rebar would be applied on Styrofoam surfaces with low diameter. For this purpose, Flat Fix Spacer has been designed and produced with upper part similar to Mini Fix Spacer and also a horizontal sheet below the spacer. This part does not insert into the soft & recessed surface because of bearing enough seat and resistance. Flat Fix Spacer is able to place rebar from 6 - 16 mm in diameter inside their locking tentacles and could tolerate point load up to 25-35kg according to its height as well.
 
Flat Fix Plastic Spacer has been designed in a way to be used in horizontal surfaces with light rebar network such as soft & recessed ceilings. It is not logical to use it in other light surfaces because the bottom plate may weaken the structure in a cross-section mode.
 
Flat Fix Spacer is able to place rebar with diameter 6-18mm inside its locking tentacles. But any rebar network with a diameter more than 14mm would be included in rebar networks with medium weight and is not suitable to use Flat Fix Spacer accordingly. But because the above-mentioned spacer is specifically used for soft & recessed surfaces and at present there is not any more powerful spacer with similar properties at least in Iran Market, it is necessary to calculate the weight of rebar construction and applied forces and then apply the required number of which for one square meter with regard to the point load capacity of flat fix spacer.
 
 
 
 
 
It is suggested to use Flat Fix Plastic Spacer for any constructions with rebar diameter of maximum 14 and for higher diameters it is better to use more powerful horizontal spacers such as Max Fix Spacers.
 
Be careful not to insert the rebar into the spacer along with twisting and tuning to sideways because it may break the plastic spacer tentacles.
