Solid tube for filling cast-in-place reinforced concrete beamfree building roof

Disclosed is a solid tube for filling cast-in-place reinforced concrete beamfree building roof, comprising a hard thin-wall pipe with a bottom, the tube belly used light weight filling material and a seal. The solid tube is circular, which has the advantages of compression resistant, anti-vibration, heat insulation, acoustic insulation, heat preservation and light weight. The purpose of adopting the circular in the utility model is to put the honeycombed structure principle into the use of the horizontal building structure to make the mechanical property more reasonable and to make the floors relieve of using the reinforced concrete joist, which changes the original concentrical stressed joist into innumerable dispersive space stressed girder-shaped structural system, provided with very convenient construction and transportation and wide band reduce of construction cost. 一种无梁楼盖现浇钢筋砼填充用实心管，它由带底硬质薄壁管、管腹用轻质填充材料和封口组成，实心管为圆形，具有抗压、抗振、隔热、隔音、保温、质轻等优点。本实用新型采用圆形的目的，是将蜂窝结构原理运用到水平建筑结构中去，使力学性能更加合理，使楼层免去钢筋梁，把原集中受力的梁变成无数分散空间受力的工字结构体系，施工、运输十分方便，工程造价大幅降低。
