Description

Basement bottom plate structure adopting prestress technology Technical Field The application relates to the technical field of prestressed floors, in particular to a basement floor structure adopting a prestressing technology. Background The basement structure is generally constructed by reinforcing the strength of the bottom plate by adopting a pre-stressing technique, which is a technique used in a building structure and is mainly used for enhancing the bearing capacity and the crack resistance of the structure. In the prior art, a reinforcing mesh is generally adopted to be matched with cement for pouring in a basement bottom plate structure, and a machine is used for stretching reinforcing steel bars in the solidification process of the reinforcing mesh, so that prestress is provided for the reinforcing steel bars to increase the strength of the bottom plate, but the prestress loss is caused by overlong reinforcing steel bars due to the fact that the basement is generally an overlong building, and the stress is influenced. Aiming at the related technology, the inventor considers that the length of the prestressed tendons can be reduced by splicing and laying the segmented structure, and the prestress loss caused by overlong prestressed tendons is avoided, so that the structural stability is influenced. Disclosure of utility model The application aims to provide a basement bottom plate structure adopting a prestress technology, so as to solve the problem that stress is influenced due to prestress loss caused by overlong prestress ribs. The application provides a basement bottom plate structure adopting a prestress technology, which adopts the following technical scheme: The utility model provides an adopt basement bottom plate structure of prestressing force technique, includes bottom plate, apron and a plurality of first reinforcing bars of built-in and a plurality of second reinforcing bars of built-in apron in bottom plate and the apron, be provided with the baffle on the bottom plate, baffle parallel arrangement is on the bottom plate, be provided with the connecting plate on the apron, connecting plate parallel arrangement is at the apron upper both sides edge, apron central point puts parallel connection board and is provided with the stress plate, be provided with the prestressing tendons on the stress plate, prestressing tendons both ends respectively with connecting plate fixed connection.
