Hollow floor system with stiffening columns and capable of improving local pressure-bearing performance of plate surface, box body and construction method of hollow floor system

Abstract

The invention discloses a hollow floor system with stiffening columns and capable of improving local pressure-bearing performance of a plate surface, a box body and a construction method of the hollowfloor system. The hollow floor system comprises a floor system upper plate, a floor system lower plate and a plurality of thin-wall hollow square boxes arranged between the floor system upper plate and the floor system lower plate, and plate surface steel bars and plate bottom steel bars are arranged in the floor system upper plate and the floor system lower plate correspondingly; the plate surface steel bars and the plate bottom steel bars between the adjacent thin-wall hollow square boxes are further connected through tie bars; a plurality of parallel vertically-through stiffening holes areformed in the middles of the thin-wall hollow square boxes, when the floor system is poured, the vertically-through stiffening holes are also filled with concrete to form point type supporting stiffening columns, the stiffening columns, the floor system upper plate and the floor system lower plate are integrally formed, and the distance between the every two adjacent stiffening columns is smallerthan the width of a truck tire. The hollow floor system can greatly improve the bearing capacity of a top plate of the box body area.

Description

technical field

[0001] The invention relates to the field of hollow floors, in particular to a hollow floor with stiffening columns, a box body and a construction method for improving the local pressure bearing performance of the slab surface. Background technique

[0002] With the continuous development of construction technology, on the basis of conventional cast-in-place reinforced concrete ribbed floors and beamless floors, hollow floors have gradually been widely used. As a new type of floor system, it is poured by regularly arranging a certain number of permanent thin-walled boxes in the cast-in-place concrete floor.

[0003] Due to the setting of the thin-walled box, the hollow floor has the advantages of less concrete consumption and light weight, which can shorten the construction period, improve the sound insulation effect and reduce the structural cost. Its economic and technical indicators are significantly improved compared with other types of floor systems. . ...
