Specific embodiment
The present invention is described in further detail with reference to the accompanying drawing.
As shown in Figure 1, the production method of the mechanical-moulded dry concrete bottom plate of the present invention includes:
Reinforced mesh 2 and deformed bar 3,3 edge of deformed bar are laid in the extrusion molding dies 1 of production line
The length direction setting of extrusion molding dies 1, simultaneously prestressed reinforcement of tensioning 3 pass through the fixed prestressing force of presstressed reinforcing steel anchorage 4
The both ends of reinforcing bar 3；
Extrusion forming in extrusion molding dies 1 will be expected under dry concrete；
It is conserved in the top covering curing film of molding dry concrete bottom plate；
After molding dry concrete bottom plate reaches intensity, deformed bar 3 is cut off, retains beard muscle 8；
With lifting machinery starting board, piled up to rickyard.
It is described to expect that extrusion forming includes: in extrusion molding dies 1 under dry concrete
Dry concrete proportion is carried out by design and calculates dry concrete dosage, by prepared dry coagulation
Soil is packed into concrete shaping equipment 6 by hopper；
The concrete shaping equipment 6 is set to the top of extrusion molding dies 1 and along 1 liang of extrusion molding dies
The track 7 that side is equipped with is walked, and the concrete shaping equipment 6 will expect extrusion molding dies under dry concrete automatically
It in 1 and vibrates to dry concrete baseplate molding, staff carries out stand-by supervision；
It is laid with before reinforced mesh 2 and deformed bar 3 in extrusion molding dies 1, is being squeezed into for the ease of starting board
Diaphragm agent is smeared on the inner wall of pattern tool 1.
For the ease of lifting, setting is hung while being laid with reinforced mesh 2 and deformed bar 3 on extrusion molding dies 1
One end of hook 9, the suspension hook 9 is embedded in dry concrete in advance, and the other end exposes to mechanical-moulded dry concrete bottom plate
Outside.
In the present embodiment, the concrete shaping equipment 6 uses synovial membrane machine.
As in Figure 2-4, the mechanical-moulded dry concrete bottom plate of the present invention uses dry concrete extrusion forming, institute
It states and is equipped with reinforced mesh 2 and deformed bar 3 in mechanical-moulded dry concrete bottom plate, the deformed bar 3 is along length
It spends direction setting and both ends is stretched out by the both ends of the mechanical-moulded dry concrete bottom plate, form beard muscle 8.The beard
Muscle 8 is extended by deformed bar 3 in mechanical-moulded dry concrete bottom plate and is generated, and with supporting beam one-piece casting, has very
Good globality.The mechanical-moulded dry concrete bottom plate is equipped at least two convenient for the suspension hook 9 of lifting.Machinery at
Type dry concrete bottom plate has preset suspension hook 9 in extrusion forming, so that liberalization that is mobile, stacking or lift is realized,
Convenience is brought to production, transport and installation.
Pressure hair pulling treatment is made using machine printed in the upper surface of mechanical-moulded dry concrete bottom plate, meets overlapping
Surface concrete shearing resistance problem.So that plucking scale more standardizes accurately, artificial hacking randomness bring security risk is eliminated.
Laminated floor slab, reinforced mesh 2 and deformed bar 3 made of the present invention mechanical-moulded dry concrete bottom plate
Bending resistance is undertaken before forming laminated floor slab and controls the effect of amount of deflection, participates in undertaking floow load effect after forming laminated floor slab,
Compared with girder rib laminated floor slab, bending resistance truss bars are no longer equipped with, avoid the truss bars only performance in bottom plate lifting
Effect phenomenon saves a large amount of reinforcing bars.
It makes a service test below to the mechanical-moulded dry concrete bottom plate of 2000mm × 3000mm:
As shown in Fig. 5 a-7, this test is loaded using sandbag graded loading way.Loads at different levels are respectively as follows:
2.5KN/m2、2.75KN/m2、3KN/m2、3.25KN/m2、3.5KN/m2、3.75KN/m2、4KN/m2、4.17KN m2.Added
It carries, unloads load step by step by loading scheme after the completion of load.
The mechanical-moulded dry concrete bottom plate each point displacement-payload data of 2000mm × 3000mm is as follows: being displaced in table
Unit is mm.
By above-mentioned test it is found that its performance of mechanical-moulded dry concrete bottom plate with ribbing satisfaction design of the invention is wanted
It asks, is 4.17kN/m in maximum working load2In the case where, the mid-span deflection of plate is only 4.73mm, far smaller than design specification
Defined 3000/200=15mm limit value, and concrete density is preferable, the factorial production quality is also easy to control.
