The construction of the foundation to be a fairly exact science. If everything is not calculated correctly, many questions arise. The experts have developed a variety of construction techniques and tricks that are used to avoid the potential pitfalls during the construction process. One of these during use plastic slip sheets. A slip sheet as reinforcement has been successfully used for years in the construction industry.
What separates the plastic sheet?
slip a piece of plastic sheet, typically polyethylene. It can be made of different thickness, but is often used in a 10ml form. As its name suggests, the skid plate is used to reduce friction and do not move or slip. The plastic divider sheets as reinforcement to the foundation to help prevent cracking.
The Post-Tension Process
Slab-on-grade foundations is one of the most commonly used types of foundations in the United States. These foundations can quickly and inexpensively build (which is why it is so popular); However, they may be prone to cracking during the curing stage. Concrete also shrinks as it dries; this can cause cosmetic damage to the future of floor coverings like tile, vinyl, wood and carpet. Soil type – the so-called expansive soils – which eventually causes the shrinkage and cracking. Extensive soil shrinks and swells as the water content changes.
In order to avoid the cracks, the process of separating the plastic cards commonly used. This process is called post-stressing. PT squeezes the concrete, which helps to resist shrinking, cracking and caused heavy soil conditions. In order to make a post-voltage base plate, steel fibers running through the concrete square pattern. All steel is covered with a plastic cover that protects the steel from corrosion and allows you to move the emphasis during the operation. The fiber has a fixing both ends. All units, as well as the cabinet and recording, called a tendon. One end of
The post-tensioning method, the tendons are generally stressed along; Sometimes, however, he pointed at both ends along. When stressed, the steel stretches – but held in place by the lock. This acts to compress the concrete, which in turn operates to crack the concrete.
How a plastic separator sheets can be used for post-tensioning?
The plastic sheets are installed in the separator immediately below the plate or slab and the bearing surface. They work to the tendons that move the floor smoothly over all the earth. Without the slip sheets, tendons is not a smooth, even surface over which to move. Tendons must be able to easily move over the ground in order to properly stress the steel, since this is the only way in which the concrete is compacted in order to avoid the shrinkage and cracking.
If you were the architects neglected to install a plastic divider sheets – or, if they were to install them incorrectly – the roof would resist moving to prevent the post-tensioning process to be successful.
