Specific embodiment
The present invention is described in further detail with reference to the accompanying drawing.
As shown in Figure 1, a kind of production method of mechanical-moulded dry concrete bottom plate with ribbing of the present invention includes:
It is laid with reinforced mesh 2 and deformed bar 3 in extrusion molding dies 1 in production line, while setting up rib of slab branch Support reinforcing bar 5;
Pass through the both ends of the fixed deformed bar 3 of presstressed reinforcing steel anchorage 6, prestressed reinforcement of tensioning 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 with ribbing;
After molding dry concrete bottom plate with ribbing reaches intensity, deformed bar 3 is cut off, retains beard muscle 10;
Starting board is 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 concrete amount, by the dry concrete 7 prepared by expecting Bucket pours into concrete shaping equipment 8;
The concrete shaping equipment 8 is set to the top of extrusion molding dies 1 and along 1 liang of extrusion molding dies The track 9 that side is equipped with is walked, and the concrete shaping equipment 8 will expect extrusion molding dies under dry concrete automatically It in 1 and vibrates to dry concrete baseplate molding with ribbing, staff carries out stand-by supervision.
After molding, for the ease of starting board, it is laid with before reinforced mesh 2 and deformed bar 3 in extrusion molding dies 1, Diaphragm agent is smeared on the inner wall of extrusion molding dies 1.
After molding, for the ease of starting board lifting, extrusion forming in extrusion molding dies 1 will be being expected under dry concrete When, lifting hole(eyelet) 12 is reserved on rib of slab 4.
As in Figure 2-4, the mechanical-moulded dry concrete bottom plate with ribbing uses dry concrete extrusion forming, Including floor body and at least one rib of slab 4, the rib of slab 4 is set to the side of floor body, the bottom plate along its length It is equipped with reinforced mesh 2 and deformed bar 3 in main body, is equipped with the rib of slab branch being erected on deformed bar 3 in the rib of slab 4 Support reinforcing bar 5.
The deformed bar 3 is arranged along the length direction of mechanical-moulded dry concrete bottom plate with ribbing, described pre- to answer The both ends of power reinforcing bar 3 are stretched out by the both ends of the mechanical-moulded dry concrete bottom plate with ribbing, form beard muscle 10.The beard Muscle 10 and supporting beam one-piece casting have good globality.
The both ends of the rib of slab 4 are respectively equipped with a lifting hole(eyelet) 12 convenient for lifting, to realize mobile, stacking or lifting Liberalization, bring convenience to production, transport and installation.Light material 11 is laid on the floor body between rib of slab 4, such as Benzene plate, lightweight concrete, plastics cavity etc..
The mechanical-moulded dry concrete bottom plate with ribbing of the present invention by dry concrete disposable machine uniformly extrusion forming, by It is mechanical-moulded instead of artificial cloth mould, by plsitive mold instead of traditional steel die, by dry concrete instead of Moist concrete greatly improves production efficiency, saves die cost, shortens curing cycle.
Laminated floor slab made of mechanical-moulded dry concrete bottom plate with ribbing is adopted through the invention, reinforced mesh 2 and pre- Stress reinforcing bar 3 undertakes bending resistance before forming laminated floor slab and controls the effect of amount of deflection, participates in undertaking flooring after forming laminated floor slab Load action is no longer equipped with bending resistance truss bars, avoids truss bars and only hang in bottom plate compared with girder rib laminated floor slab Play a role phenomenon when dress, saves a large amount of reinforcing bars.
In mechanical presses forming process, the rib of slab 4 of formation can effectively increase the rigidity of floor, increase floor be applicable in across Degree.Concrete between rib of slab 4 is substituted using light material, can greatly reduce self weight and the arrangement of reinforcement of floor.Machine of the invention Pressure hair pulling treatment is made using machine printed in the upper surface of tool molding dry concrete bottom plate with ribbing, meets superposed surfaces coagulation Native shearing resistance problem.So that plucking scale more standardizes accurately, artificial hacking randomness bring security risk is eliminated.
It makes a service test below to the mechanical-moulded dry concrete of 2000mm × 4800mm bottom plate with ribbing:
As shown in Fig. 5 a-7, this test is loaded using sandbag graded loading way.Loads at different levels are respectively as follows: 2.50KN/m2、3.15KN/m2、3.56KN/m2、3.83KN/m2、4.10KN/m2、4.36KN m2、4.63KN/m2.It is loaded, Load is unloaded step by step by loading scheme after the completion of load.
The mechanical-moulded dry concrete of 2000mm × 4800mm bottom plate each point displacement-payload data with ribbing is as follows: in table Displacement 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 4.63kN/m in maximum working load2In the case where, the mid-span deflection of plate is only 13.01mm, far smaller than design specification Defined 4800/200=24mm limit value, and concrete density is preferable, the factorial production quality is also easy to control.
