Double fix spacer

Description

Double fix spacer

The base part of the Double Fix spacer is designed for the lower reinforcement mesh of the slab, and the head part is for the upper mesh. The Double Fix spacer can withstand a point load of 150 to 200 kilograms, depending on the spacer’s height. The base part, due to its sufficient width, can accommodate rebar of various sizes, but for maximum load-bearing capacity, it is recommended that the rebar diameter does not exceed 28 millimeters. The head part of the spacer can hold rebar up to a maximum diameter of 18 millimeters.

In many concrete structure projects, concrete slabs are typically used, which require the placement of two rows or mesh of reinforcement bars for strengthening the concrete. If separate spacers are used for each row of rebar, it would not be economically efficient and, in many cases, the lower row’s spacers may interfere with the positioning of the upper mesh. Therefore, the Double Fix spacer has been designed and produced. This spacer consists of two parts: a base and a head, which fit together.

This plastic spacer allows for the adjustment of the horizontal distance between the two reinforcement meshes and accurately maintains the spacing and alignment of the rebar in concrete structures. The main feature of this spacer is to precisely maintain the horizontal spacing between the two reinforcement meshes, ensuring that the rebar’s placement and alignment are done accurately in concrete slab structures.

The Double Fix spacer is composed of two parts, the base and the head, which are assembled inside each other. The base of this spacer is intended for placing the lower rebar mesh in a concrete slab, while the head is designed for placing the upper rebar mesh. These spacers serve two main purposes: first, they maintain the spacing of the rebar, and second, they help stabilize the alignment of the reinforcement bars in the concrete structure. This type of spacer is commonly used in concrete slabs and thick floor structures that require two rows of reinforcement bars for strengthening.

Features Double fix spacer

Applications Double fix spacer

• This spacer is capable of withstanding a point load between 150 to 200 kilograms.
• The maximum rebar diameter that can be placed on the base of the Double Fix spacer is 28 millimeters.
• The plastic cover head of this spacer can hold rebars with a maximum diameter of 18 millimeters.
• The special design of the spacer base with two different arms allows the rebars to be placed in a staggered arrangement on top of each other.

How to Use the

To use the Double Fix plastic spacer, first insert the male or head part into the groove in the base and press it in until it reaches the bottom of the base. Then, place the reinforcement bars of the lower mesh on the base. Note that the height of the two legs of the Double Fix spacer differs from the other two legs, allowing the bars to be positioned in a “cutting” manner on top of each other. After arranging the lower mesh reinforcement bars, place the upper mesh reinforcement bars in the prongs of the Double Fix head.

For Heavy Two-Axis Slabs:

To calculate the number of spacers needed per square meter, determine the weight of the reinforcement mesh and consider the load-bearing capacity of the Double Fix spacer. If the reinforcement mesh is heavier than usual, you can use the Hard Fix spacer as a supplementary option for both the upper and lower meshes, placed 1 to 2 meters apart.

For Normal Weight Two-Mesh Slabs:

The standard use is 4 Double Fix spacers per square meter.
