Description
Technical field
The present invention relates to a kind of building floor, particularly relate to a kind of mechanical-moulded dry concrete with ribbing
Base plate and preparation method thereof.
Background technology
In traditional building floor design and construction, general employing cast-in-place concrete floor form, due to
Steel bar meter, colligation, template construct and support, concreting are the completeest with maintenance molding
Become, processing place, labour cost, template are used and cause bigger waste, the most also to building periphery
Environment defines pollution.
The application of laminated floor slab technology solves this difficult problem, and this technology is that the base plate of floor is pre-in factory
After making, transport to job site, is placed in architecture storey position by design requirement lifting, and thereon
Arrange certain reinforcing bar, then casting concrete defines and prefabricated adds cast-in-place laminated floor slab, such prefabricated panel
Just can eliminate, as the template of part cast-in-place on it, the bed die operation supporting floor, save a large amount of
Template and labour cost, accelerate construction speed, and meanwhile, the reinforcing bar arranged in prefabricated panel can be as folded
The bottom steel bar stress of plywood uses, and decreases the processing capacity of on-the-spot reinforcing bar, has saved processing place.
But owing to the making of precast concrete base plate still uses moist concrete to build the conventional art of mold forming,
Affected by human intervention so that Product Precision, difficult quality guarantee, be concurrently there are curing period length, life
Product efficiency is low, high in cost of production drawback.
Summary of the invention
For the problems referred to above, it is an object of the invention to provide a kind of mechanical-moulded dry concrete end with ribbing

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 bag of the present invention a kind of mechanical-moulded dry concrete base plate with ribbing
Include:
Laying reinforced mesh 2 and deformed bar 3, frame simultaneously in extrusion molding dies 1 at production line
If rib of slab spacer bar 5；
The two ends of described deformed bar 3, prestressed reinforcement of tensioning 3 is fixed by presstressed reinforcing steel anchorage 6；
In extrusion molding dies 1 being expected under dry concrete extruded；
Above the dry concrete base plate with ribbing of molding, covering curing thin film carries out maintenance；
After the dry concrete base plate with ribbing of molding reaches intensity, cut off deformed bar 3, retain beard
Muscle 10；
Play plate, 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 concrete amount, the dry coagulation that will prepare
Soil 7 is poured in concrete shaping equipment 8 by hopper；
Described concrete shaping equipment 8 is arranged at the top of extrusion molding dies 1 and along being squeezed into
The track 9 that mould 1 both sides are provided with is walked, and described concrete shaping equipment 8 is automatic by dry
Concrete discharging is interior to extrusion molding dies 1 and vibrates to dry concrete baseplate molding with ribbing, work
Stand-by supervision is carried out as personnel.
After molding, for the ease of playing plate, in extrusion molding dies 1, lay reinforced mesh 2 and prestressing force
Before reinforcing bar 3, the inwall of extrusion molding dies 1 is smeared barrier film agent.
After molding, for the ease of playing plate lifting, extrusion molding dies 1 will expected under dry concrete
In extruded time, reserved lifting hole(eyelet) 12 on rib of slab 4.
As in Figure 2-4, described mechanical-moulded dry concrete base plate with ribbing uses dry concrete
Extruded, including floor body and at least one rib of slab 4, described rib of slab 4 is arranged at the end along its length
The side of plate main body, is equipped with reinforced mesh 2 and deformed bar 3, described rib of slab in described floor body
The rib of slab spacer bar 5 being erected on deformed bar 3 it is provided with in 4.
Described deformed bar 3 is arranged along the length direction of mechanical-moulded dry concrete base plate with ribbing, described
The two ends of deformed bar 3 are stretched out by the two ends of described mechanical-moulded dry concrete base plate with ribbing, shape
Become beard muscle 8.This beard muscle 8 and support beam one-piece casting, have good globality.
Described rib of slab 4 be respectively arranged at two ends with a lifting hole(eyelet) 12 being easy to lifting, it is achieved thereby that mobile,
Stack or the liberalization of lifting, give and produce, transport and installation brings facility.Described floor body upper plate
Light material 11 is laid, such as benzene plate, lightweight concrete, plastics cavity etc. between rib 4.
The mechanical-moulded dry concrete of present invention base plate with ribbing is extruded by dry concrete disposable machine uniformly
Molding, be instead of artificial cloth mould by mechanical-moulded, plsitive mold instead of traditional steel die, by
Dry concrete instead of moist concrete, is greatly improved production efficiency, saving die cost, shortens and support
Protect the cycle.
The laminated floor slab made by the present invention mechanical-moulded dry concrete base plate with ribbing is adopted, reinforced mesh 2
Before forming laminated floor slab, undertake bending resistance and the effect controlling amount of deflection with deformed bar 3, form overlapping building
Participate in after plate undertaking floow load effect, compared with girder rib laminated floor slab, be no longer provided with bending resistance Truss Steel
Muscle, it is to avoid truss bars only plays a role when base plate lifts phenomenon, saves a large amount of reinforcing bar.
In mechanical presses forming process, the rib of slab 4 of formation can be effectively increased the rigidity of floor, strengthens
Floor is suitable for span.Concrete between rib of slab 4 uses light material to substitute, and can greatly reduce floor
Deadweight and arrangement of reinforcement.The upper surface of the mechanical-moulded dry concrete base plate with ribbing of the present invention uses machinery
Embossing is made to force wharf's pavement quality, meets superposed surfaces anti-shear concrete problem.Make plucking yardstick more specification
Accurately, the potential safety hazard that artificial hacking randomness is brought is eliminated.
Dry concrete mechanical-moulded to 2000mm × 4800mm base plate with ribbing 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
It is respectively as follows: 2.50KN/m2、3.15KN/m2、3.56KN/m2、3.83KN/m2、4.10KN/m2、4.36KN
m2、4.63KN/m2.Load, after having loaded, load is unloaded step by step by loading scheme.
The mechanical-moulded dry concrete of 2000mm × 4800mm base plate with ribbing each point displacement-payload data is such as
Under: in table, 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 4.63kN/m at maximum working load2In the case of, the mid-span deflection of plate is only
13.01mm, is far smaller than the 4800/200=24mm limit value that design specification specifies, and concrete density is relatively
Good, factorial praluction quality is also easy to control.
