Abstract

The invention discloses a combined system floor system and a construction method thereof, and belongs to the technical field of constructional engineering. According to the structure, a box body component is provided with an inter-ribbed beam, a plurality of sets of prestressed tendon components of a square structure are vertically arranged in the inter-ribbed beam, and upper-layer steel bars and bottom plate steel bars located over and under the prestressed tendon components penetrate through the prestressed steel bars. The prestressed rib components are additionally arranged in the rib beams of the box body components, so that the net-shaped rib beam structure with the I-shaped section in the floor can bear loads more effectively, and the performance of the floor is improved. The prestressing technology and the BDF hollow floor slab technology are combined, the advantages of the prestressing technology are fully exerted, the deflection of the BDF hollow floor slab is reduced, floor slab cracks are restrained, and the hidden danger of water seepage is avoided.

Description

technical field

[0001] The invention belongs to the technical field of construction engineering, and particularly relates to a combined system floor and a construction method thereof. Background technique

[0002] With the continuous advancement of urbanization, buildings are gradually developing in the direction of super-large span and super-large space. Ordinary reinforced concrete cast-in-place floor slabs can no longer meet this structural form. Therefore, BDF hollow core slab technology came into being, and has mature. However, engineering examples in recent years have shown that as the span of the building structure becomes larger and larger, the deflection of the BDF hollow floor slab gradually increases, resulting in cracks in the hollow core floor, which will lead to water leakage and other phenomena. SUMMARY OF THE INVENTION

[0003] In order to solve the technical problems existing in the above background technology, the present invention provides a combined sy...
