Technical field
The utility model is related to the precast floor unit in a kind of building engineering field, be more specifically it is a kind of be applied to it is more
The steel bar girder sandwich precast floor slab of layer or high-rise steel structure engineering, internal partition, Side fascia, plate can also be used as across 3.0 meters of left sides
It is right short to be used across loading plate or long span non-bearing roofing board.
Background technology
At present, the floor in architectural engineering is broadly divided into two major classes --- precast floor slab and cast-in-situ floor.But traditional two
Kind floor all exposes respective shortcoming and defect at leisure in use.
Precast floor slab does not occur larger changes and improvements technically for many years, substantially or with hollow hole
Based on the concrete floor in hole.Major defect existing for such a concrete floor is：Plate is heavy, heavy, shock resistance is poor, not sound insulation,
It is not incubated, needs repeatedly lifting and transhipment, manually installed difficulty（Individual plates are general all more than 350 kilograms, during fine position not
Conveniently move）, and easily occur plate stitch after assembling due to being completely independent, lacking reliable connection between adjacent floor deck, influence
Attractive in appearance, globality poor.
For cast-in-situ floor, live formwork erection, cast-in-site, although eliminating the trouble for repeatedly lifting and transporting,
It is to need to build substantial amounts of scaffold, the lumps of wood and plank sheathing in place limited at the scene, manual branch mold process is cumbersome, work is strong
Spend big, time-consuming, laborious, with greatly improving for labor cost, this mode is more and more uneconomical, and wastes a large amount of timber moneys
Source.
In recent years, steel structure frame formula building was more and more, i.e., is arrived first using as the steel column of main support, steel girder erection
Position, floor, lining, Side fascia and steel column, the girder steel of subsequent installation are attached and fixed again.Then there have been a kind of generation
For the corrugated steel cast-in-situ floor of traditional plank sheathing：Corrugated steel is positioned on girder steel, directly by the use of corrugated steel as
Building template, while the bottom reinforcement bars as floor again.Although corrugated steel cast-in-situ floor can save traditional plank sheathing and tear open
The trouble of mould, but the exposed corrugated steel of floor slab bottoms unsightly, difficulty coats；Structure fire poor performance, steel plate once by
Bearing capacity of floor slab just substantially reduces after heat；In addition, as the problem of reinforcing bar detraction also be present in steel plate corrosion.Therefore, this ripple
Steel plate cast-in-situ floor is limited significantly using upper, is only used at present in Small-scale redevelopment engineering and fitting-out work, is failed a large amount of
It is generalized in multilayer, high-rise steel structure engineering.
At present in multilayer, high-rise steel structure engineering, most widely used cast-in-place concrete floor formwork erection plate technique, is one
Kind be called the technology of " steel bar truss floor support plate ", and with the immediate prior art of the utility model.Steel bar truss floor support plate
Core component be triangle steel bar girder, i.e., arranged, put into along horizontal Longitudinal extending by a upper cage bar, two lower cage bars
Cross section be triangle component.In other words, as a horizontal bottom and two inclinations are formd between three cage bars
Side, it is provided with two inclined sides and is longitudinally continuous the diagonal bar for curving wave extension and is welded with upper and lower cage bar.And

The horizontal bottom of truss is fixed and is welded on one piece of thin galvanized steel plain sheet, that is, forming one piece 60 centimeters wide, length can arbitrarily set
Steel form, steel bar truss floor support plate is fixed on girder steel, then direct casting concrete slurry.It is cast-in-place with above-mentioned corrugated steel
Floor is compared, and the thin galvanized steel plain sheet of steel bar truss floor support plate bottom is flat board, and only plays temporary support concrete, in building
Thin galvanized steel plain sheet is with regard to ineffective after board concrete solidification, because the triangle steel bar girder in floor just constitutes floor requirement
Arrangement of reinforcement, bearing requirements can be met.Therefore, the thin galvanized steel plain sheet of bottom can be removed after floorslab concrete solidification.
In addition, triangle steel bar girder can continuously be welded by automatic welder, machining accuracy height, efficiency high, good economy performance.Meanwhile steel
Formwork erection mode of the muscle truss floor support plate as main flow in current multilayer, high-rise steel structure engineering, save substantial amounts of shuttering and
Labour cost, also save substantial amounts of timber resources.It is disadvantageous in that：The thin galvanized steel plain sheet of manual demolition needs to expend necessarily
Manpower, and the galvanized steel plain sheet majority gross distortion removed, so reprocessing can only be melted down when waste product, this also results in one newly
Waste.
Compare from construction weight merely, either floor or wallboard, be mostly on the premise of same breadth, equal thickness
The weight of Bars In Poured Concrete Slab is more than prefabricated board（Such as most general office building, spot-cast concrete floor-slab thickness are 10 centimeters, conduct oneself with dignity every square
240 kilograms, and common prefabricated board is typically in 170-180 kilograms/square meter）, therefore Bars In Poured Concrete Slab has no in terms of construction weight is mitigated
