Hidden frame dense rib cavity floor

Abstract

The invention discloses a hidden frame dense rib cavity floor. The hidden frame dense rib cavity floor comprises a frame beam, dense rib beams and prefabricated cavity components inset between the frame beam and the dense rib beams or among the dense rib beams. The hidden frame dense rib cavity floor is characterized in that the every prefabricated cavity component is a cavity together defined by an upper plate, surrounding side walls and a lower plate, at least two neighboring side edges of the lower plate are respectively provided with lower jetting-out edges which jet outwards, at least two neighboring side edges of the upper plate are respectively provided with upper jetting-out edges which jet outwards, and the frame beam and the dense rib beams are packed between the lower jetting-out edges and the upper jetting-out edges. The hidden frame dense rib cavity floor is mainly applicable to floors formed in one step by pouring concrete in industrial and civil buildings, the top surface of the floor and the ground are flat and smooth, the appearance is neat and attractive, the step of manual leveling can be saved, a flat working surface can be provided for subsequent floor decoration, construction costs are saved and the construction period is shortened.

Description

technical field [0001] The invention relates to a cavity floor, in particular to a cavity floor with a hidden frame and dense ribs. Background technique [0002] With the rapid development of the economy, the urbanization process is accelerating, and the population is rapidly gathering in the city. Urban buildings are increasingly unable to meet people's needs for space, and urban buildings are striving to expand towards multiple and high-rise buildings. The acceleration of urban construction has also led to many revolutionary breakthroughs in construction technology, and one of them, the hollow floor technology, is eye-catching for its unique advantages. [0003] Hollow floor technology originated from the prestressed hollow concrete prefabricated slabs in the 1960s and 1970s. Later, the method of laying hollow circular tubes and then pouring concrete became the second generation product of hollow floors, and finally developed to the current stage of embedding hollow boxes....

AI Technical Summary

Problems solved by technology

For example, after concrete pouring and maintenance are completed, it will shrink and sink to a certain extent due to its own physical characteristics, and the entire floor will look uneven, which will affect the appeara
