Mini fix spacer

In many concrete sections, due to the low concrete thickness or the expected lower strength, low-diameter rebars (less than 12 mm) or some thermal rebars are used. Such concrete sections and structures include concreting block beam ceilings, steel deck ceilings, various types of floors and ceilings woven with lightweight rebar networks, and the production of prefabricated concrete parts. In these structures, the weight of the rebar network and the operational loads are naturally lower than other structural elements, and mini-fix plastic spacers can be used to create a suitable concrete cover for the rebars. This group of spacers is capable of accommodating rebars with a diameter of 6 to 16 mm inside their locking lugs. Mini-fix spacers are mainly used in steel structures with a maximum rebar diameter of 12 mm. Minifix lightweight plastic spacers are designed and manufactured with lower weight and volume than similar items and are much more economical. Minifix plastic spacers are capable of withstanding a point load of 25 to 35 kg, and this difference in point load capacity will change with decreasing or increasing the height of the spacer. Since the sections stated for using Minifix plastic spacers are generally light, placing 4 spacers per square meter will meet the necessary expectations. However, if there is a structure with a denser and heavier reinforcement network, the number of spacers required for use in one square meter should be obtained by calculating the weight of the reinforcing network per square meter and considering the point load capacity of the Minifix spacer.

In general, this rebar spacer, like other parts for rebar holders, is made of strong plastic and can also be used to hold rebar networks in light structural ceilings. This mini-fix plastic spacer is considered one of the most widely used floor and ceiling spacers in construction, and also, by vertically spacing under the reinforcing mesh and formwork of the supplier, it ensures proper concrete coverage, in accordance with the technical specifications and thickness specified in the regulations of Section 9 of the National Building Regulations.

This plastic spacer is a special type of concrete spacer that is used to create the appropriate distance between the rebars and the concrete formwork. This type of spacer is very useful in construction due to its small size and special design. The Minifix spacer is an efficient and essential tool in concrete projects. Using these spacers not only helps improve the quality and durability of the structure but also increases efficiency and reduces maintenance costs in the long term.

What should be considered when using Minifix plastic spacers?

• The Mini Fix plastic spacer is designed to be used on horizontal surfaces with light rebar grids, such as ceilings.
• It is recommended to use Minifix plastic spacers for structures with a maximum rebar diameter of 12, and for higher diameters, stronger horizontal spacers should be used.
• The Mini Fix plastic spacer has the ability to accommodate rebars with a diameter of 6 to 18 mm inside its prongs. However, this ability does not mean that it can withstand the load imposed by rebar structures with a large rebar diameter, because the Mini Fix plastic cover is designed for light horizontal surfaces with a point load capacity of up to 35 kg. If the diameter of the rebars is within the mentioned range, but the weight of the structure is high, stronger spacers such as the Max Fix or Hard Fix spacers should be used.
• Note that inserting the rebar into the plastic concrete spacer should not be accompanied by twisting or turning it sideways, as this may cause the prongs of the Minifix plastic spacer to break.
• If, after calculating the weight of the reinforcing mesh per square meter and considering the live and dead loads, the values ​​obtained are higher than the capacity of the Mini Fix rebar spacer. Increasing the number of plastic covers of the reinforcement in order to spread the applied forces is not logical and cost-effective, and it is better to use a stronger plastic spacer, such as Max Fix, because it has a point load capacity about 4 times higher than that of Mini Fix and naturally requires the use of fewer spacers per square meter. On the other hand, reducing the number of spacers and choosing the appropriate type will be much less expensive in terms of economy and implementation time.
