Product Descriptionprecast prestressed half floor slab/lattice
girder floor casting bedBrief introduction:Long line casting beds
form the basis of the highly productive extrusion and slipforming
processes employed in the production of prestressed hollow floor
products, some solid walls and sandwich wall panels, beams and
lintels.This prestressed long line table half slab production line
developed by Haitian company, is with mature technology,
reasonable design, high degree of automation, easy to operate. It
is an ideal choice for those precast plants who focus on large
scale half slab production.Technical advantage:Higher production
efficiency; (150% more than Pallet circulation production
line) Factory floor space is smaller; Greatly reduce labor demand;
(9-10 people) High utilization rate of die table; (The utilization
rate of the mold can reach more than 90%) Significant reduction in
investment costs; (equivalent to 70%-80% of Pallet
circulation production line cost) Easier and safer operation;
Component pass rate is higher; Components cost less to
produce. Detailed PhotosAbout half floor slab:A half floor
slab/lattice girder floor is a reinforced concrete slab with a
minimum thickness of 5-7cm.The thickness ofthe finished floors lab
is between 12cm and 30cm, depending on the span and the loading.The
fundamental benefits are amongst other things a high-quality
product at a reasonable price, extreme dimensioning vers at lity
and rapid on-siteinstallation.The floors lab contains the steel
truss that is required to give stiffness once installed, as
well as the flexural tension reinforcement, lengthways and
crossways, that is required for assembly and the final state.The
floors lab is made into a solid and monolithic reinforced concrete
floor by using mix-in-situ concrete that is poured at the
construction site and allows them to cooperate while bearing
loads.Both floor layers are joint by lattice girders placed in an
in-situ cast concrete and by rough precast element
surface.Application:Floor span within 8 meters, can be widely used
in hotels, office buildings, schools, residences, hospitals,
warehouses, parking lots, multi-storey industrial plants and other
housing construction projects. Compared with non-prestressed
composite plates, the former can save steel bars and reduce costs
under the same load strength, and can effectively improve the span
of composite plates under the same amount of steel. Main
equipment 1.Concrete casting tableconventional 2.85*9m/set
(size can be customized), multiple mold tables are spliced into a
long-line production platform, and the side mold can be placed in
the length direction to effectively improve the utilization of the
mold table;Heated pipes can be laid for later stage steaming of
half floor slabs;Insulation plate at the bottom prevents heat
loss during component steaming and saves costs.2.Concrete feeder:1)
the equipment consists of walking device, hopper, electronic
control system;2) The system is equipped with anti-collision
parking mechanism, overload protection and other devices to ensure
stable performance and stable operation. The whole machine is easy
to operate, safe and reliable.3.Distributor&vibration
machine:Complete concrete pouring and vibration compaction of
lattice girder floor slabs;Concrete pouring is done by a
distributor machine. The distributor machine is used to accurately
distribute for the prefabricated components of the half floor slab,
including the position of the concrete cloth, the thickness of the
concrete distribution, the total amount of the concrete of the
single piece, etc;Vibrating system complete vibration compaction of
concrete.4.Multi-functional bed cleaner On the surface of the
steel platform after demoulding, there is a coagulation residue
falling off the component, and the cleaning mechine will finely
clean the surface of the casting table;When the motor cleaning
brush cleans the concrete at high speed, the concrete dust is
absorbed, filtered, and dusted by the dust collecting device for
the generated concrete dust;The device runs forward through the
mold bottom surface, the spraying device starts to spray the
release agent automatically, and the high-pressure ultra-fine
atomizing nozzle is used to evenly spray release agent oil film on
the surface;When producing prestressed laminated slabs, the
tensioning equipment guides the steel from one end to the
other end ,prepare for the next tensioning station.Greatly reduce
the labor intensity of workers and improve work
efficiency.5.Tensioning machine:Tension can be customized according
to demand (1000-3000kN);After the steel is laid,tensioning steel is
to prepare for pre-stressed components next vibration. At the end
of the release, release the tensioned prestressed steel when the
concrete reaches sufficient strength.6.Roughening
machine/Multi-functional Cover roller:Roughing the lattice girder
floor slab before steaming, making the surface rough and
improving the surface adhesion
