Truss screed is a key equipment in the concrete casting process, especially for large-scale road construction projects. In the construction industry, concrete casting is a very crucial stage. This is because the truss screed will determine the durability and performance of the final foundation structure. Especially in highway projects that require a flat and strong surface to withstand heavy traffic loads.
Truss screed, as one of the key pieces of equipment, is designed to level and compact fresh concrete mix efficiently. The presence of truss screed is a top priority in large projects. It reduces surface defects such as cracks or unevenness that could potentially lead to safety issues and long-term maintenance costs. This process is often associated with "striking off", where the concrete is at its lowest viscosity, allowing for optimal spreading.
Description of Truss Screed
Truss screed is a concrete finishing machine consisting of a truss frame equipped with a vibration bar and a drive mechanism. The design can be used in large areas, up to 10-20 meters wide. More ideal for casting concrete slabs in road construction. Unlike the limited manual screed, this truss screed can integrate vibration to compact the concrete simultaneously to level the surface. According to industrial floor construction guidelines, truss screeds are often supported by temporary rails or forms to achieve precision tolerances. In addition though it is not recommended for surfaces with very high precision requirements without laser assistance. It is typically operated by two to four workers, with adjustable operating speeds to match the viscosity of the concrete.
Advantages of Truss Screed Compared to Other Leveling Tools
There are several advantages of Truss Screed over manual leveling methods (power screed), namely:
- Strong frame stability, so that the vibration is more evenly distributed over the entire length of the tool.
- Work time efficiency, enabling faster completion of the casting.
- More professional resultsThe concrete surface is smooth, even, and ready for the final finishing stage.
- Ability to work on wide surfaces that ordinary power screeds cannot reach.
