Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated: precast concrete composite floor as shown in Fig. 1,2, comprise precast plate 3 and the pre-buried girder steel 4 in the bottom surface of described precast plate.
Described pre-buried girder steel 4 is the consistent hat shape steel of shape of cross section or U-shaped steel, and longitudinally run through the main body of described precast plate completely or substantially, many described pre-buried girder steels in a row be arranged in parallel.
Described pre-buried girder steel is provided with and turns up for a pair or the upper flange of varus, and it is inner that the described upper flange of pre-buried girder steel and part web are embedded in described precast plate in advance, and all the other webs of pre-buried girder steel and lower wing plate are suspended from the subjacent of described precast plate 3.The lower wing plate of pre-buried girder steel directly can connect maintenance panel conveniently by tapping screw, and maintenance panel uses fire proofing material, and has the beam action of protection pre-buried steel.Can pipeline installation in maintenance panel, and the connector between polylith floor.
The combination of pre-buried girder steel and precast plate greatly strengthens the flexural strength of precast plate, therefore precast plate thickness can be reduced, and alleviates weight simultaneously and reduces cost.The steel beam web plate of floor slab bottoms directly can lift maintenance panel easily, the structure of carrying out lifting construction in addition is relatively needed to be equivalent to increase spatial altitude, and simplify construction, reduce the spacing between maintenance panel and floor and facilitate construction, reducing construction cost.
Described precast plate is light reinforced concrete prefabricated component, and laid inside has steel mesh, steel plate, shaped steel or steel wire.Make the lightweight of floor, intensity is high.
A pair upper flange of described pre-buried girder steel 4 is welded with steel mesh, or is laterally in columnly welded with steel wire, the spacing between steel wire in column is 100mm.Steel mesh or steel wire are played a supporting role to pre-buried girder steel.
As Fig. 2, a contiguous lateral edges of described precast plate 3 or the bottom surface of both sides of the edge are embedded with multiple embedded sleeve barrel 2, the bottom surface of described embedded sleeve barrel is opened on the bottom surface of described precast plate, and spliced side by side by embedded sleeve barrel and connector for polylith floor, floor spiced structure as shown in Figure 3.The inner surface of described embedded sleeve barrel 2 is provided with screw thread, for being directly fastenedly connected adjacent precast plate with nut by floor connector 7.By embedded sleeve barrel, floor is side by side spliced into one, makes floor entirety more firm.
The end of the one or both ends of described precast plate is embedded with built-in connection 1 at the end face of precast plate.As shown in Figure 1, described built-in connection 1 part is embedded in the inside of described precast plate 3, and part stretches out the surface of precast plate.Built-in connection can be used for carrying out assembled with the structural connection of wall or post easily, and the comprehensive factoryization realizing floor construction body is produced, and realizes site operation volume dry type assembledization.
Or described built-in connection 1 part is embedded in the inside of described precast plate 3, external surface is smooth in the end face of precast plate.Also the assembled of floor and other structural members can be realized neatly by welding angle steel at built-in connection place.
