Problems solved by technology

[0003] Concrete densely ribbed floor is an excellent structure with light weight, less material, high bearing capacity, and small space occupation. Especially its dense rib arrangement makes it capable of carrying concentrated loads, so that it has the ability to meet various The performance of the use function, but because the concrete ribbed floor requires very complicated construction molds, the use of traditional wooden molds, bamboo molds,

Abstract

The invention discloses a fabricated floor system and a construction method. The fabricated floor system is composed of prefabricated ribs and prefabricated floor slabs, or a plurality of prefabricated floor system units which are composed of the prefabricated ribs and the prefabricated floor slabs and prefabricated bottom plates are directly supported on a bottom support for being assembled and connected at a construction site to form the entire floor system, and the entire floor system is supported on a main beam or a pillar after the bottom support is removed. The slabs of the floor systemunits of the fabricated floor system are completely prefabricated, all or most of the ribs and beams of the floor system units are prefabricated in a factory, and the prefabricated ribs (beams) of theadjacent floor system units are connected to the entire rib-beam floor system by adopting cast-in-place concrete laminated ribs (beams), or laminated flanges or pressure grouting during on-site construction installation. According to the fabricated floor system and the construction method, the fabricated floor system is prefabricated in bathes in the factory according to standard rib (beam) slabunits, and a lot of construction period can be saved; and the prefabricated rib (beam) slab units serve as formworks of the ribs (beams), the formworks of cast-in-place laminated ribs (beams) or the laminated flanges are omitted, so that construction is convenient and quick.

Description

technical field [0001] The invention relates to a floor, in particular to an assembled dense-ribbed floor which adopts prefabricated concrete floor units and does not need beam-slab molds for construction and a construction method thereof. Background technique [0002] The most commonly used traditional molds for concrete floor construction are wooden molds, bamboo molds, steel molds, aluminum alloy molds, etc. Wooden molds and bamboo molds are generally reused about five times, so the use efficiency is low and a lot of wood resources are consumed , causing a large number of forests to be cut down, causing ecological damage and environmental pollution. Steel molds and aluminum alloy molds have a high number of reuses, but their affinity with concrete is too good, and a release agent is required to release the mold, which increases the construction process and labor costs. In addition, the steel mold has a large weight It increases the difficulty of installation, and the eas...
