The specific embodiment
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
The structural representation of composite floor system cross section shown in Figure 1; only show a part among the figure; only have a girder 1 and with girder 1 a spaced apart secondary beam 2 and a part of composite floor plate 8; girder 1 can be steel work or reinforced concrete structure or steel and concrete combination construction with secondary beam 2, and composite floor plate 8 comprises sound-insulating plate 4, cast-in-place armored concrete slab 3, fireprotection layer 5 and anticracking topping 6.Sound-insulating plate 4 is arranged between the spandrel girder, top is provided with some grooves, and the sound-insulating plate is polystyrene foam plastics EPS plate (expansion type) or XPS plate (extrusion type), perhaps adopts foam glass board or other hard insulating material; Cast-in-place armored concrete slab 3 is positioned at the upside of sound-insulating plate 4, merge with the groove kissing of sound-insulating plate 4 and be the wave trough shape, cast-in-situ reinforced concrete slab 3 is cast in girder 1 and secondary beam 2, and the soffit of girder 1 and secondary beam 2 is not embedded in the concrete slab and exposes outside; Fireprotection layer 5 is arranged at the downside of sound-insulating plate 4; fireprotection layer can be fireproof mortar or PLASTIC LAMINATED or mineral wool board or rock cotton board or fire-resistant gypsum panel; anticracking topping 6 is arranged on the downside of fireprotection layer 5, and it comprises the polymer mortar layer 10 that is arranged on fireprotection layer 5 bottoms and spread upon fiberglass gridding cloth both sides about in the of 9.When fireprotection layer was fireproof paint, fireprotection layer was arranged on the outside of anticracking topping, promptly was coated in the outside of anticracking topping, and then fiberglass gridding cloth 9 is arranged on the downside of sound-insulating plate.
Upper surface at above-mentioned girder and secondary beam also can vertically be provided with several steel pegs, and together is cast in the concrete slab, like this, makes the common stressed formation compound beam of beam and floor, makes that it is shockproof, anti-seismic performance is better, and can save steel.
Above-mentioned sound-insulating plate as rock cotton board or mineral wool board, then can save fireprotection layer if adopt fire-type, and the anticracking topping directly is set.
In the structure of above-mentioned composite floor plate, the sound-insulating plate also can be set to not establish groove, thus armored concrete slab then be shaped to flat, also in protection domain of the present utility model.
In the structure of above-mentioned composite floor plate, warming plate will promptly be removed behind the armored concrete slab moulding by casting only as mould, and such structure is also within protection domain of the present utility model.
The manufacturing process of the utility model composite floor system is as follows: as shown in Figure 2, adopt bolt 16 and connector to hang the bottom that is installed in girder 1 and secondary beam 2 light-duty latticed hollow steel template 17, if the span of primary and secondary beam is bigger, can take in the template bottom interim support or increase interim crossbeam on primary and secondary beam top adopt bolt to pass floor layer to hang template; Sound-insulating plate 4 is cut into the wave trough shape by design size to be laid on above the template 17, also can be on warming plate crest or trough place dovetail groove is set, to increase the connection of cast in place concrete plate and warming plate, can be concordant with the bottom surface of secondary beam or be higher than time soffit in the bottom surface of warming plate, warming plate be arranged between the girder or girder and secondary beam between; The steel mesh reinforcement 7 that laying is made up of main muscle and arrangement of reinforcement on warming plate, top mat need stride across girder and time top surface of the beam continuous distributed, continuous concrete placing layer on warming plate and on the primary and secondary beam, after the moulding, warming plate and concrete slab closely combine, and primary and secondary beam and concrete pouring are together; At this moment, remove support shuttering, install and fix fireprotection layer, can adopt bonding and rivet clasp in the bottom of sound-insulating plate and primary and secondary beam; Paste laying anticracking topping in the bottom of fireprotection layer.So promptly make composite floor system.
In the actual fabrication process; also can the furred ceiling layer be set in the warming plate bottom; select fire-resistant gypsum panel or other PLASTIC LAMINATED for use; perhaps on gypsum plank, place thin layer foam glass cotton; rock wool or mineral wool class fire proofing material; perhaps directly certain hard PLASTIC LAMINATED be placed on sound-insulating plate above the template below; on PLASTIC LAMINATED, install and lay warming plate; the nylon crab-bolt of interval mounting strap pallet on PLASTIC LAMINATED; and upwards penetrate warming plate and insert the cast-in-situ concrete layer; be bound up by cast-in-situ concrete; constitute PLASTIC LAMINATED; double-deck and the compound floor slab structure of concrete slab of warming plate, laying anticracking topping below it.
Fig. 3 is the schematic diagram of another embodiment of the utility model composite floor system, its structure and manufacturing process and the foregoing description are basic identical, are that cast-in-place concrete slab all is cast in its inside with the girder of steel and the secondary beam of steel, simultaneously, configuration reinforcement around the girder steel, form steel framed concrete beam, or claim the strengthening concrete beam, can increase the bearing strength of beam like this, reduce the section area of girder steel, reduce rolled steel dosage, thereby can reduce cost, and conserve space.
Fig. 4 is the schematic diagram that the utility model composite floor system and exterior wall combined wall board combine, during making at first the outside cast-in-place light concrete along supporting member 14 and girder 1 constitute the exterior wall combined wall board, the exterior wall combined wall board is cast-in-place during to girder 1 end face, along girder place ecto-entad continuously to the top pouring concrete of warming plate and primary and secondary beam.
Profiled sheet cast-in-situ concrete composite floor system shown in Figure 5; profiled sheet 19 is set serves as mould; bottom interval at profiled sheet 19 is provided with spandrel girder 20; steel mesh reinforcement and fluid concrete are set on profiled sheet 19; armored concrete slab is cast in, laying haydite concrete bed course 12 on armored concrete slab with profiled sheet.The utility model composite floor system is compared with it, because there is not the height h1 of haydite concrete bed course 12, and the primary and secondary beam has been cast in the middle of the layer of concrete, so the utility model composite floor system height has reduced the height of h1+h3.
The utility model composite floor system is applicable to frame structure system, is particularly useful for the floor construction of steel structure system and steel and concrete composite structure system, constitutes the floor construction of frame system.
