Cement pad can replace plastic pad!
It is well known that in order to ensure the thickness of the protective layer of steel, it is often necessary to preform the mortar pad at the construction site.
This kind of mortar premade cushion block is generally made of M15 mortar: first, the mortar is smoothed and compacted according to the thickness of steel reinforcement protective layer on the ground; after its initial solidification, the mortar is divided into small pieces about 30mm square by a tile; and two iron wires about 20cm long are pressed into the small square for binding wire.
When the mortar strength reaches the requirement, the mortar pad is formed.
The steel reinforcement engineer can tie up the steel protective layer pad according to the design requirements after the reinforcement is tied and the formwork is set up.
This kind of mortar prefabricated cushion is made of mortar and its strength is not high, so it is easily broken: it is bound to the steel bar by the iron wire in the cushion block, because the iron wire is not connected to the cushion block, the cushion block is easy to fall off;
Its bind is troublesome, operate inconvenience, work efficiency is not high.
Due to the thickness of the steel reinforcement protective layer is not enough or too thick, which leads to the quality problem of non-uniform stress on the components, which is often caused by the unqualified mortar pad.
Is there any substitute with good performance and convenient operation?
Yes, that's concrete spacer.
Concrete spacer has the following features:
Concrete spacer is made of plastic.
Its strength is high, and the compressive strength is greater than 4.
2MPa, tensile strength greater than 4MPa, impact resistance, not broken.
Concrete spacer is fixed on the steel bar by means of clamp, which has strong self-locking force and is not easy to fall off.
Concrete spacer is an industrial product with uniform specifications and good consistency.
Concrete spacer is easy to install, and you can press it with your hand when you are working. It saves labor, time and money.
Concrete spacer is used as a reinforcing steel protective layer cushion block, which is beneficial to eliminate common defects in concrete construction and improve the construction quality of concrete.
Therefore, since the advent of the cement block, its sales are expanding, and there is a trend to replace the traditional mortar premade block.
