Description
Technical field
The present invention relates to the precast floor unit in a kind of building engineering field, be more specifically it is a kind of be applied to multilayer or
The steel bar girder sandwich precast floor slab of high-rise steel structure engineering, can also be as internal partition, Side fascia, plate across 3.0 meters or so
It is short to use 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
Plant floor and all expose 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.The major defect that such a concrete floor is present is：Plate is heavy, heaviness, poor shock resistance, 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 due to being completely independent, lacking reliable connection between adjacent floor deck, easily there is plate stitch after assembling, influence
Attractive in appearance, globality poor.
For cast-in-situ floor, live formwork erection, cast-in-site, although eliminate the trouble for repeatedly lifting and transporting, but
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
Degree is big, time-consuming, laborious, and 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., will be arrived first 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 a kind of generation has been occurred as soon as
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 again as the bottom reinforcement bars of floor.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 is just substantially reduced after heat；In addition, with steel plate corrosion also there is reinforcing bar detraction the problem of.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
The technology for being called " steel bar truss floor support plate " is planted, is also with inventing immediate prior art.The core of steel bar truss floor support plate
Component is triangle steel bar girder, i.e., arranged by a upper cage bar, two lower cage bars along horizontal Longitudinal extending, put it is transversal
Face is the component of triangle.In other words, as a horizontal bottom and two inclined sides are formd between three cage bars,
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 steel bar girder
Floor support plate is exactly that the triangle steel bar girder that will be welded three is one group, in uniform mode by the water of three triangle steel bar girders
Planar base surface is fixed and is welded on one piece of thin galvanized steel plain sheet, that is, constitutes the steel form that one piece 60 centimeters wide, length can arbitrarily be set, will
Steel bar truss floor support plate is fixed on girder steel, then direct casting concrete slurry.Compared with above-mentioned corrugated steel cast-in-situ floor,
The thin galvanized steel plain sheet of steel bar truss floor support plate bottom is flat board, and only plays temporary support concrete, in floorslab concrete
Thin galvanized steel plain sheet is just ineffective after solidification, because the triangle steel bar girder in floor just constitutes the arrangement of reinforcement of floor requirement,
Bearing requirements can be met.Therefore, the thin galvanized steel plain sheet of bottom can be removed after floorslab concrete solidification.In addition, three
Angle steel bar girder can continuously be welded by automatic welder, machining accuracy height, efficiency high, good economy performance.Meanwhile, steel bar girder building
Board saves substantial amounts of shuttering and labour cost as the formwork erection mode of main flow in current multilayer, high-rise steel structure engineering,
Also save substantial amounts of timber resources.It is disadvantageous in that：The thin galvanized steel plain sheet of manual demolition needs to expend certain manpower, and
The most gross distortions of galvanized steel plain sheet removed, so can only work as waste product melts down reprocessing, this also results in a new 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（For example most general office building, spot-cast concrete floor-slab thickness are 10 centimeters, are conducted oneself with dignity every square
240 kilograms, and common prefabricated board is general in 170-180 kilograms/square meter）, therefore Bars In Poured Concrete Slab has no in terms of construction weight is mitigated
Advantage, and also have no the feasible method for mitigating construction weight in the construction technology of Bars In Poured Concrete Slab at present.Pushed greatly in current country
Under the background of the assembled architecture of row energy-saving and environmental protection, in this field of building floor, have the technique for improving precast floor slab only, subtract
The deadweight of light floor, the assembly performance for improving floor is only the direction of technological innovation, and this is also the reason place of the present invention.
