What is it called? A detailed guide to the names of plastic rebar spacers
Searching for building materials on the Internet often turns into a quest due to the difference between official technical names and popular slang. Today we will try to understand the nomenclature of the most popular plastic fasteners.
A rebar spacer is an element used to create and fix a precise distance between two parts of a structure, and in our case, to form a protective layer.
1. A rebar wheel spacer (For vertical structures)
This element is used to form a protective layer of concrete in walls, columns, pylons, foundations and reinforced concrete rings. Its round shape with flexible rays allows the part to be easily put on the reinforcement and slide on the formwork panels during installation.
Options:
A rebar wheel spacer is most commonly referred as a rebar spacer wheel, plastic wheel spacer, cartwheel spacer, or spider wheel.
2. A rebar chair spacer (For a solid horizontal base)
It is used exclusively on hard surfaces: concrete preparation, floor slabs or metal corrugated sheets. It withstands the heavy weight of the iron frame when workers walk on it during pouring.
Options:
A rebar chair spacer is also widely known as a rebar chair, reinforcement chair, chair bar, or rebar support.
3. A round plate mesh spacer (For loose and soft horizontal surfaces)
The main difference from a regular stand is the presence of a wide round or square plastic «skirt» (base), which prevents the thin legs from piercing the waterproofing or sinking in sand, gravel, or polystyrene foam.
Options: It is most commonly known as a grade plate spacer or mesh fix spacer.
4. A plastic end cone (For panel formwork systems)
This element is the only one on the list that holds not reinforcement, but formwork elements. It is put on at both ends on a plastic PVC tube, inside of which a steel tie screw passes. The cone is pressed tightly against the wooden shield and protects the internal cavity from leaking liquid concrete.
Options: A plastic end cone — most commonly used in concrete construction to protect tie rods and space formwork — is also known as a tie rod cone, thruty cone, formwork cone, PVC cone, or shuttering cone.
Now, using any of these names, you can easily find the positions you need on manufacturers' websites or construction marketplaces.
If you are planning a purchase, please specify: what type of structure you are building and what diameter of reinforcement you need the clamps for. And we will help you to choose the right option and calculate the optimal number of pieces per square meter.
