Double Reinforced Joist Spacer

Double Reinforced Joist Spacer

The Double Reinforced Joist Spacer is an efficient product designed to ensure the correct spacing for precast trusses and placing them inside metal molds for beams or fondoles. This spacer not only has two locking mechanisms on its sides but also features two central locking slots for securing reinforcement bars. The Double Reinforced Joist Spacer can also be used in modern construction technologies, such as hollow core slab ceilings (waffle slabs), where direct truss installation can be achieved using only the trusses and spacers placed in the empty spaces between waffle blocks. The spacer accommodates rebar sizes from 6 mm to 14 mm and can withstand a point load of up to 50 kg.

For many years, the use of standard prefabricated trusses for beam construction has been a common practice. These trusses are produced in factories according to the client’s specifications and then transported to the project or truss manufacturing site. During transport, unloading, or loading, the angle or alignment of the trusses may shift or become distorted. To resolve this, the plastic double reinforced truss spacer is designed with standard dimensions and the capability to accommodate two reinforcing bars.

This product is a plastic spacer designed to keep the rebar in place within concrete structures. The difference between this spacer and the single reinforced joist spacer lies in its design and application. The Double Reinforced Joist Spacer is suitable for structures with two or more layers of rebar. Correct usage of this spacer can significantly improve the durability and strength of concrete structures, and it is especially important in large or complex projects.

Features of the Double Reinforced Joist Spacer

• Can support a point load of up to 50 kg
• Accommodates rebar sizes from 6 mm to 14 mm
• Suitable for use in structures with multiple layers of rebar

How to Use the Double Reinforced Joist Spacer

1. Transporting Trusses:
   • During the transfer of precast trusses from the factory to the site, the spacer is installed on the main rebar of the trusses to prevent deformation during transport. The trusses are then loaded onto the vehicle.
2. Making Beams:
   • The spacer is placed at the required intervals inside the metal truss mold. The truss is then inserted, and the reinforcing rebar is secured within the spacer’s locking features.
3. Using in Waffle Slab Molds:
   • The plastic truss spacers are placed at regular intervals between the waffle blocks. The trusses are inserted into the spacer’s arms, and the reinforcing rebar is positioned.

Important Notes Regarding the Double Reinforced Joist Spacer

• Not using this product can result in significant damage due to deformation of trusses, bending of beams, and structural weakness.
• The use of the plastic double reinforced truss spacer significantly reduces beam construction costs, transport time, and execution time in hollow core slab projects.
• Using this spacer ensures the production of high-quality beams, with all necessary details in compliance with industry standards.
