Abstract
The invention discloses a reinforced concrete hollow floor slab, which comprises a cast-in-situ multi-rib (1), a cast-in-situ crest slab (2) and a prefabricated soleplate (3). The prefabricated soleplate (3) is formed by joining a top prefabricated block (7) and a bottom prefabricated block (8). The bottom prefabricated block (8) is provided with more than two notches (6). An upper notch of the bottom prefabricated block (8) is used for placing the top prefabricated block (7) to form the prefabricated soleplate (3). A lower notch of the bottom prefabricated block (8) is mutually engaged with a bottom projection (5) of the cast-in-situ multi-rib (1). When producing the hollow floor slab, the cast-in-situ multi-rib (1) and the cast-in-situ crest slab (2) are firstly poured, and then a reinforcement fabric (11) and the prefabricated soleplate (3) are arranged on the bottom projection (5) of the cast-in-situ multi-rib (1) or on a projection (5) which is coated with mortar (12); the cast-in-situ multi-rib (1), the cast-in-situ crest slab (2) and the prefabricated soleplate (3) form a cavity (4); and the mortar (12) is painted below the prefabricated soleplate (3) to form an integral hollow floor slab. The hollow floor slab has good integrity, large rigidness, high bearing capacity, long service life and simple construction procedure.

Summary of the invention:
The object of the present invention is to provide that a kind of feed consumption is few, cost is low, good integrity, and the prefabricated units volume is little, in light weight, simple structure is convenient to make, transportation, the reinforced concrete hollow floor of convenient, fast construction.
The objective of the invention is to realize like this; A kind of reinforced concrete hollow floor; This cassette ceiling comprises cast-in-place close rib, cast-in-place top board, prefabricated panel, forms cavity by cast-in-place close rib, cast-in-place top board, prefabricated panel, the invention is characterized in that described prefabricated panel is assembled by top prefabricated section and bottom prefabricated section; On the prefabricated section of bottom the breach more than two is arranged; Wherein, the breach on prefabricated section top, bottom is used to place the top prefabricated section and forms prefabricated panel, and the breach of prefabricated section bottom, bottom and cast-in-place close rib bottom projection are engaged.Described cassette ceiling forms cavity by cast-in-place close rib, cast-in-place top board, prefabricated panel, cast-in-place close rib, cast-in-place top board and prefabricated panel acting in conjunction, and good integrity, rigidity is big, can alleviate floor weight behind the formation cavity.Simultaneously, also there is cavity the prefabricated panel inside that is formed by top prefabricated section and bottom prefabricated section, has reduced the steel concrete consumption, has alleviated weight, and prefabricated panel can mechanization production, has accelerated speed of application.The breach on the prefabricated section top, bottom of prefabricated panel is used to place the top prefabricated section, forms prefabricated panel, and the breach of prefabricated section bottom, bottom and the mutual interlock of cast-in-place close rib bottom projection make the cassette ceiling good integrity.
Characteristic of the present invention also is on the prefabricated section of described bottom rib is arranged, and the rib on the prefabricated section of bottom can be vertical rib, cross rib or crisscross rib, has effectively improved the strength and stiffness of prefabricated panel.
Characteristic of the present invention also is on the prefabricated section of described bottom filler is arranged, and filler is a light material, and functions such as insulation, heat insulation, sound insulation are arranged.
Characteristic of the present invention also is under the described prefabricated panel steel mesh reinforcement is arranged, and can improve the globality and the cracking resistance of prefabricated panel.
Projection is arranged at described cast-in-place close rib bottom, and projection is as the bearing of prefabricated panel.When making reinforced concrete hollow floor, steel mesh reinforcement, prefabricated panel are placed on the projection of cast-in-place close rib bottom, smear one deck mortar in the prefabricated panel bottom surface, form whole cassette ceiling, good integrity, easy construction is quick.
