The closed floor bearing plate has been proved to have stronger bearing capacity and shear resistance by experiments. The special design of the closed rib shape allows the steel bearing plate's rib to be completely covered by concrete, just like the reinforcement in the cast-in-place slab, so that they can give full play to their respective characteristics, and have been successfully applied to the floor bearing plate system with stress reinforcement, and have very good fire resistance performance. Do you know the advantages of installation technology of closed floor bearing plate compared with ordinary open plate? Jinan floor bearing plate manufacturer will analyze for you:
1. When arranging the bearing plates of the closed floor, it is only necessary to arrange them in sequence according to the span. When connecting with the steel beam in sequence, due to the flat bottom of the plate, there is enough area to connect with the steel beam. Therefore, it can be paved directly without treatment (the opening plate needs to be cut and repaired to avoid false overlap with the steel beam).
2. The opening plate shall be blocked at the port to prevent the concrete pouring from leaking from the opening at the bottom of the plate, while the closed floor bearing plate does not need to be blocked at the end due to the closure of the web.
3. Due to the flat bottom of the plate, the bearing plate of the closed floor can be fully combined with the upper flange of the steel beam, regardless of whether it is horizontally or vertically lapped with the steel beam, so the top surface of the upper flange of the steel beam does not need to be sprayed with fireproof paint. However, there is a hole between the open steel bearing plate and the steel beam, so it is necessary to fill the hole with shoulder plugs.
4. The closed floor bearing plate can completely replace the lower reinforcement, reduce the amount of on-site reinforcement fabrication, reduce the amount of on-site labor and speed up the construction. At the same time, the original design of the lower reinforcement is canceled, which can provide more space for laying wire sleeves in the floor.
In addition, the above advantages can significantly speed up the processing speed and shorten the construction period. Therefore, the use of closed floor bearing plate can reduce the direct cost of the project on the one hand, and reduce the cost of the project pipeline on the other hand.
