Prefabricated multi-ribbed plate

Abstract

The invention discloses a prefabricated multi-ribbed plate. The prefabricated multi-ribbed plate comprises a reinforced concrete plate, longitudinal ribs, transverse ribs and a steel bar truss, the reinforced concrete plate is composed of steel bar meshes and concrete, the multiple longitudinal ribs which are longitudinally arranged are arranged on the lower portion of the reinforced concrete plate, the longitudinal ribs are composed of longitudinal rib concrete and longitudinal rib steel bars, at least one transverse rib which is transversely arranged is arranged on the lower portion of the reinforced concrete plate, the transverse rib is vertically arranged in the middle of the longitudinal rib, at least one steel bar truss which is transversely arranged is embedded in the position, close to the end, of the upper portion of the reinforced concrete plate, the upper portion of the steel bar truss is exposed out of the reinforced concrete plate by a certain height, and the longitudinalrib, the transverse rib and the reinforced concrete plate are poured into a whole. The prefabricated multi-ribbed plate is high in rigidity, small in steel consumption and low in manufacturing cost, the inter-rib deformation coordination performance can be improved through combination of the main ribs and the transverse partition ribs which intersect transversely and longitudinally, and the overload capacity under the action of local loads is improved.

Description

technical field [0001] The invention relates to concrete prefabricated components, in particular to a prefabricated dense rib plate. Background technique [0002] Floor slabs in traditional frame structures usually use formwork for floor pouring. There are many formwork procedures and quality control is difficult. If a prefabricated building is used, the slab span is generally not greater than 3 meters. Otherwise, support is required, and the floor slab is economical. In order to carry out rapid construction without formwork during floor construction, the inventor has disclosed a patent for using a permanent steel truss floor deck or a closed steel deck as both a building formwork and as a stressed steel bar at the bottom of the floor. Formwork construction, simple process, small beam spacing, large number of beams, and when the building structure has a large load and a large span, the amount of steel used for the floor slab is large, and the coordination of the lateral defo...

Problems solved by technology

[0002] Floor slabs in traditional frame structures usually use formwork for floor pouring. There are many formwork procedures and the quality is difficult to control. If a prefabricated building is used, the slab span is generally not greater than 3 meters. Otherwise, support is required, and the floor is economical.

In order to carry out rapid construction without formwork during floor construction, the inventor has disclosed a patent to use permanent steel truss floor decks or closed steel decks as both building formwork and as stressed steel bars at the bottom of the floor. Formwork construction, simple process, small beam spacing, large number of beams, and when the building structure has a large load and a large span, the amount of steel used for the floor slab is large, and the coordination of the lateral deformation of the steel slab is poor, which is inconsistent with the calculation assumption of the equivalent uniform load. Unable to reduce the number of prefabricated beams

There is no report on a prefabricated dense-rib slab with large span, large load, simple construction, and good integrity for one-way force transmission.
