But from the overall comparison, reinforced truss slab is much more economical than ordinary floor slab, which is mainly reflected in the following aspects:
1. The binding amount of steel bars on the site of steel truss is about 5kg, and that of ordinary floor is 12kg.
2. Temporary support, the maximum unsupported span of reinforced truss plate can be set to 4.8m, and the maximum span of ordinary floor plate is 3m, which requires a lot of temporary support.
3. Man-hour, the steel truss plate greatly saves the on-site labor and man-hour, and the management cost and labor cost are greatly reduced.
4. Advance the construction period and win economic benefits in advance.
5. There is no need for fire-cutting report, and the performance of reinforced truss slab is basically the same as that of traditional cast-in-place slab, and there is no maintenance cost in the later period.
Therefore, for the general contractor and the owner, the overall comparison of cost and overall economic benefit is more scientific and practical.
