Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the cross section structure schematic diagram of the utility model precast concrete plank first embodiment;
Fig. 2 is the cross section structure schematic diagram of the utility model precast concrete plank second embodiment.
The specific embodiment
Precast concrete plank of the present utility model comprises by reinforcing bar and wraps up the plate-like body that the concrete of described reinforcing bar is formed, the thickness of this plate-like body is more than or equal to 40mm, the distance of the interior reinforcing bar of plate that its upper surface is nearest is more than or equal to 15mm, and the distance of the interior reinforcing bar of plate that soffit is nearest is more than or equal to 15mm.
As shown in Figure 1, be the cross section structure schematic diagram of precast concrete plank first embodiment of the present utility model.This precast concrete plank comprises the plate-like body of being made up of reinforcing bar in the plate 12 and concrete 11 10, wherein reinforcing bar 12 is formed (for example netted, framework etc.) by many with the reinforcing bar that interfixes in the plate, " skeleton " of similar plate-like body 11, concrete 11 then wrap up reinforcing bar 12 in the plate.When building, at first reinforcing bar in the plate 12 is placed in the mould, at fill concrete in mould, harden fully at concrete and to remove mould and make plate-like body 10.
When above-mentioned precast concrete plank when the solid floor, in the nearest plate of the soffit of plate-like body 10 reinforcing bar 12 should be at least 15mm apart from d2, preferably be not less than 25mm.Correspondingly, the minimum thickness d3 of the plate-like body 10 of this moment is at least 40mm, is recommended as 50mm; Reinforcing bar 12 should be more than or equal to 15mm apart from d1 in the nearest plate of the upper surface of plate-like body 10.When precast concrete plank is room external application floor, the floor of the balcony of building for example, this moment, the soffit of plate-like body 10 should be more than or equal to 15mm apart from the distance of reinforcing bar in the plate, be preferably 35mm and more than.
In addition, on plate-like body 10, also be provided with the bottom and be embedded in the girder rib that plate-like body 10, top are exposed plate-like body 10 upper surfaces.This girder rib by with plate in the fixing lower edge muscle 14 of reinforcing bar 12, the lattice muscle 16 that winds up muscle 15 and be connected wind up muscle 15 and lower edge muscle 14 that is positioned on plate-like body 10 upper surfaces form.Above-mentioned muscle 15 and the lower edge muscle 14 of winding up is parallel to each other.
As shown in Figure 2, be the cross section structure schematic diagram of precast concrete plank second embodiment of the present utility model.The precast concrete plank of this embodiment comprises the plate-like body of being made up of reinforcing bar in the plate 22 and concrete 21 20 equally, also is embedded with the girder rib of being made up of the muscle 25 that winds up, lower edge muscle 24 and lattice muscle 26 in the plate-like body 20.
Different with first embodiment, in the present embodiment, the upper surface of being close to plate-like body 20 also is fixed with lightweight filler 27, so that this plate is applicable to the occasion of large span.In the bottom of above-mentioned lightweight filler 27 and the nearest plate reinforcing bar apart from d7 more than or equal to 15mm or 20mm.Correspondingly, the thickness d 5 of plate-like body 20 should preferably be not less than 65mm more than or equal to 50mm at this moment; In the nearest plate of the soffit of plate-like body 10 reinforcing bar 12 should be at least 15mm apart from d4, preferably be not less than 25mm.
