Description

A kind of steel bar truss floor support plate being applied in combination with cast-in-situ wall
Technical field
The present invention relates to the technical fields of building structure, more particularly to a kind of and cast-in-situ wall group
Close the steel bar truss floor support plate used.
Background technique
It is well known that steel bar truss floor support plate is in factory process by the reinforcing bar in floor into reinforcing bar
Truss, and the gang form that steel bar girder and zinc-plated profiled sheet are welded into one.In construction rank
Section, steel bar truss floor support plate provide strength and stiffness by steel bar girder, bear construction loads, directly
It connects and is routed on beam, by the mutual snapping of bed die, coagulation can be poured by carrying out simple reinforced bar engineering
Soil.In service stage, steel bar girder is exactly the arrangement of reinforcement of concrete floor, to bear working load.
Existing steel bar truss floor support plate can only use in steel construction, because of its steel in laying construction
Muscle truss floor support plate need to be fixed with girder steel with welding of peg, but cast-in-situ wall is different from girder steel material
Matter, steel bar truss floor support plate can not be welded and fixed with cast-in-situ wall, higher using limitation;Mesh
Before, cast-in-situ wall structure can only be using erection template, installing arrangement of reinforcement, casting concrete and disassembly
The mode of template is constructed, the common in-situ reinforced concrete slab construction stage because of lower part formwork thus base
This is without amount of deflection, the demoulding after concrete reaches some strength, under Gravitative Loads, underfloor
It scratches, board bottom concrete generates pulling force, or even crack occurs, and rigidity is lower, makes so as to cause it
It is poor with reliability;Simultaneously because traditional cast-in-situ floor construction need to set up and dismantle template, engineering
Amount is big, and construction efficiency is low.
Summary of the invention
In order to solve the above technical problems, the present invention provides one kind can cooperate with cast-in-situ wall structure
It uses, reduces and use limitation;And strengthening floor slab rigidity can be improved, improve use reliability;
The process that need to set up and dismantle template when conventional floors construction is saved, project amount is reduced, raising is applied
The steel bar truss floor support plate of work efficiency rate.
The steel bar truss floor support plate that a kind of and cast-in-situ wall of the invention is applied in combination, including three groups
Steel bar girder, intermittent configuration bed die and multiple groups bed die support angle steel, on the intermittent configuration bed die
Be provided with left folding while and when right folding, and three groups of " V " type ribs are provided on intermittent configuration bed die,
The multiple groups bed die support angle steel is installed in intermittent configuration bed die bottom.
The steel bar truss floor support plate that a kind of and cast-in-situ wall of the invention is applied in combination, described three groups
In steel bar girder, every group of steel bar girder includes two lower edge reinforcing bars, the reinforcing bar that winds up, two
Web member reinforcing bar, several support vertical reinforcements and several support horizontal reinforcements, several supports are vertical
Reinforcing bar top with the reinforcement welding that winds up, and between several support vertical reinforcement bottom ends both pass through
Disconnected structure bed die is simultaneously welded with corresponding bed die support angle steel, several support horizontal reinforcements respectively
Respectively with several support vertical reinforced-bar-weldings and with two lower edge reinforcement weldings, two web member reinforcing bars
Top with the reinforcement welding that winds up, and two web member reinforcing bar lower half regions respectively with two
It is welded respectively with " V " corresponding on intermittent configuration bed die type rib again after lower edge reinforcement welding.
The steel bar truss floor support plate that a kind of and cast-in-situ wall of the invention is applied in combination, the interruption
Structure bed die is zinc-plated cold-rolled steel sheet, with a thickness of 0.5mm.
Compared with prior art the invention has the benefit that one kind and cast-in-situ wall of the invention
The intermittent configuration bed die being applied in combination and the bed die support angle steel with cast-in-situ wall contact portion are
Steel bar truss floor support plate is in factory according to cast-in-situ wall width in architectural drawing, spacing by reinforcing bar purlin
Frame floor support plate bed die, which is fabricated to, to be connect with wall overlap interruption without bed die, and with cast-in-situ wall
Contact portion packing sets bed die support angle steel, reaches and connect with cast-in-situ wall reserved steel bar and bed die is constant
The steel bar truss floor support plate of shape, bed die support angle steel are directly contacted with cast-in-situ wall when in use,
Play the role of supporting intermittent configuration bed die, spillage when can prevent from pouring, and can basis
The quantity of the interruption adjustment bed die support angle steel of intermittent configuration bed die, and by steel bar truss floor support plate
After no bed die piece truss is connect with the reinforcement welding reserved on wall, coagulation can be directly poured
Soil.And steel bar truss floor support plate belongs to no support combinations floor support plate, in the construction stage, reinforcing bar
Truss floor support plate can bear construction loads, directly be routed on beam, by the mutual snapping of bed die, by
Steel bar girder provides strength and stiffness, and carrying out simple reinforced bar engineering can casting concrete.?
Service stage, steel bar girder is exactly the arrangement of reinforcement of concrete floor, to bear working load.Due to
Completely instead of template function, reduce the correlative charges of template erection and demolition works, significantly
The efficiency of floor slab construction is improved, therefore it has the advantage of construction fast speed, and has cast-in-place
Overall stiffness is big, and the good advantage of anti-seismic performance, arrangement of bar is uniform, bar spacing and concrete
Protective layer thickness is reliably guaranteed.The reinforcing bar purlin that a kind of and cast-in-situ wall of the invention is applied in combination
Frame floor support plate is before concrete knot is hard, floor strength and rigidity, that is, steel bar girder intensity and just
Degree, template self weight, weight concrete and construction loads are born by steel bar girder entirely.Concrete knot
Actually it is carried out under reinforcement bar truss mould plate deformation, so floor self weight will not make board bottom concrete
Generate pulling force, in addition to floor is self-possessed permanent load and Live Loads on Floors in Buildings effect under, board bottom
Concrete just generates pulling force.In this way, floor cracking delay, the rigidity of floor is than common cast-in-place steel
Bar concrete floor is big.Lower edge reinforcing bar is total together with concrete on service stage, steel bar girder
With work, this floor and reinforced concrete sandwich formula floor stress performance having the same, although
Stress in tensile reinforcement is advanced, but its bearing capacity is identical as ordinary reinforced concrete floor.Galvanized steel
Plate bed die is only used as the template in floor slab construction stage, does not stress in service stage, when floor coagulation
After soil is poured and is conserved, dismountable bed die galvanized steel plain sheet, carry out bottom surface processing, can reach with
The identical effect in cast-in-place concrete floor bottom surface, without considering fire prevention, anti-corrosion aspect problem.And
And steel bar truss floor support plate is widely used in multi storied factory building, multilayer, high level, super high steel structure
Building, various irregular floorings, all kinds of reinforced concrete prefabricated boards, the structures such as high-speed railway and
Building field.Belong to economy, energy-saving and environmental protection, efficient, safety-type building materials.
