Embodiment Construction

[0029] The present invention will be further described below in conjunction with the examples, but it should not be understood that the scope of the subject of the present invention is limited to the following examples. Without departing from the above-mentioned technical ideas of the present invention, various replacements and changes made according to common technical knowledge and conventional means in this field shall be included in the protection scope of the present invention.

[0030] A partially prefabricated assembled post-lamination hollow floor, characterized in that it includes a cast-in-place floor floor 1, a cast-in-place rib beam slab grid 2 and a prefabricated flat plate 3. The cast-in-place floor slab 1 and the cast-in-place rib beam slab grid 2 are formed by one-time casting. The construction process is as follows: first support the bottom formwork and beam rib side formwork, tie the bottom plate and rib beam reinforcement, and then pour the bottom plate 1 an...

Abstract

The invention discloses a partially-prefabricated assembled rear-stacking hollow floor, comprising cast-in-place floor bottom slabs, a cast-in-place rib beam slab grid and prefabricated flat slabs; a bottom formwork and beam rib side formworks are erected, and bottom slab and rib beam rebars are tied; the hollow floor bottom slabs and rib beam concrete are then cast, a construction joint is reserved at the bottom of the top slabs, the prefabricated flat plates corresponding to hollows in size are lifted to the tops of rib beams, stress-bearing vertical bars connected with hidden beams are arranged correspondingly at the rib beams, and secondary casting is performed at the rib beams between the flat slabs so as to finish maintenance. The inner formwork material in the hollow floor is omitted, and two novel hollow floor structures cast by means of secondary stacking are constructed. The partially-prefabricated assembled rear-stacking hollow floor with the structure allows all aforementioned problems present in traditional hollow floors can be solved, and construction difficulty is not reduced.

Description

technical field [0001] The invention relates to the field of prefabricated buildings, in particular to hollow-core floors. Background technique [0002] Due to its small structural height, high spatial rigidity, and more economical design cost than ordinary rib-beam floors, hollow-core floors have good application prospects in long-span garages, businesses, squares, and some large-slab structures. [0003] However, the existing hollow floor needs to use the internal formwork (full cast-in-place concrete), and the following problems exist in the actual construction process: [0004] (1) The internal mold materials provided by the hollow floor internal mold suppliers do not have uniform specifications and standards. At present, the detailed design of the hollow floor can only be carried out by the internal mold suppliers according to their unique materials, and the internal mold suppliers usually It is determined by the construction general contractor. When the construction d...
