Detailed description of the invention
The present invention is described in further detail below in conjunction with the accompanying drawings.
As it is shown in figure 1, the manufacture method of the present invention mechanical-moulded dry concrete base plate includes:
In the extrusion molding dies 1 of production line, lay reinforced mesh 2 and deformed bar 3, described pre-should
Power reinforcing bar 3 is arranged and prestressed reinforcement of tensioning 3 along the length direction of extrusion molding dies 1, by advance should
The two ends of described deformed bar 3 fixed by power muscle anchorage 4；
In extrusion molding dies 1 being expected under dry concrete extruded；
Above the dry concrete base plate of molding, covering curing thin film carries out maintenance；
After the dry concrete base plate of molding reaches intensity, cut off deformed bar 3, retain beard muscle 8；
Play plate by lifting machinery, pile up to rickyard.
Described will expect extrusion molding dies 1 under dry concrete in extruded include:
Carry out dry concrete proportioning by design and calculate dry concrete consumption, dry by prepare
Rigid concrete is loaded in concrete shaping equipment 6 by hopper；
Described concrete shaping equipment 6 is arranged at the top of extrusion molding dies 1 and along being squeezed into
The track 7 that mould 1 both sides are provided with is walked, and described concrete shaping equipment 6 is automatic by dry
Concrete discharging is interior to extrusion molding dies 1 and vibrates to dry concrete baseplate molding, and work people
Member carries out stand-by supervision；
Before laying reinforced mesh 2 and deformed bar 3 in extrusion molding dies 1, for the ease of rising
Barrier film agent smeared on the inwall of extrusion molding dies 1 by plate.
For the ease of lifting, extrusion molding dies 1 is laid reinforced mesh 2 and deformed bar 3
Arranging suspension hook 9, one end of described suspension hook 9 is embedded in dry concrete in advance, and the other end exposes to machine simultaneously
The outside of tool molding dry concrete base plate.
In the present embodiment, described concrete shaping equipment 6 uses synovial membrane machine.
As in Figure 2-4, the present invention mechanical-moulded dry concrete base plate uses dry concrete to squeeze
Molded, it is equipped with reinforced mesh 2 and deformed bar 3 in described mechanical-moulded dry concrete base plate,
Described deformed bar 3 is arranged along its length and two ends are at the bottom of by described mechanical-moulded dry concrete
The two ends of plate are stretched out, and form beard muscle 8.This beard muscle 8 is by pre-in mechanical-moulded dry concrete base plate
Stress reinforcing bar 3 extends and generates, and with support beam one-piece casting, has good globality.Described machinery
At least two that is provided with of molding dry concrete base plate is easy to the suspension hook 9 of lifting.Mechanical-moulded dry
Concrete floor, when extruded, has preset suspension hook 9, it is achieved thereby that mobile, stack or lift oneself
By changing, give and produce, transport and installation brings facility.
The upper surface of mechanical-moulded dry concrete base plate uses machine printed to make to force wharf's pavement quality, full
Foot superposed surfaces anti-shear concrete problem.Make plucking yardstick more specification accurate, eliminate artificial hacking with
The potential safety hazard that meaning property is brought.
The laminated floor slab being made up of the present invention mechanical-moulded dry concrete base plate, reinforced mesh 2 is with pre-
Stress reinforcing bar 3 undertakes bending resistance and the effect controlling amount of deflection before forming laminated floor slab, after forming laminated floor slab
Participation undertakes floow load effect, compared with girder rib laminated floor slab, is no longer provided with bending resistance truss bars,
Avoid truss bars only to play a role when base plate lifts phenomenon, save a large amount of reinforcing bar.
Dry concrete base plate mechanical-moulded to 2000mm × 3000mm makes a service test below:
As shown in Fig. 5 a-7, this test uses sandbag graded loading way to load.Loads at different levels divide
It is not: 2.5KN/m2、2.75KN/m2、3KN/m2、3.25KN/m2、3.5KN/m2、3.75KN/m2、
4KN/m2、4.17KN m2.Load, after having loaded, load is unloaded step by step by loading scheme.
2000mm × 3000mm mechanical-moulded dry concrete base plate each point displacement-payload data is as follows: table
Middle displacement unit is mm.
By above-mentioned test, the mechanical-moulded dry concrete of the present invention its performance of base plate with ribbing meets
Design requirement, is 4.17kN/m at maximum working load2In the case of, the mid-span deflection of plate is only 4.73mm,
It is far smaller than the 3000/200=15mm limit value that design specification specifies, and concrete density is preferable, batch production
The quality of production is also easy to control.
