Description
Technical field
The present invention relates to the composite floor of a kind of die mould steel and straw board combination and manufacture method.
Background technology
At present, Profiled Steel Sheet and Concrete Composite Floor is the most prominent in composite floor system, also ripe, early
In nineteen thirties, people, by profiled sheet is used as permanent template, then begin to gradually recognize pressure
Shape steel plate and the combined effect of concrete, and replace steel bar stress using steel plate, therefrom recognize its superiority and gradually promote
Use.From the sixties backward, the state such as the U.S., Europe, Soviet Union has developed and published the design and construction standard of combined steel plate in succession,
Thus significantly promoted compoboard deeper into research and application.And China just starts grinding of composite floor from the eighties in 20th century
Study carefully and apply, just greatly developed after the related new technique of introduction and digestion composite floor with new technology later.Summarize
Get up, composite deck slabs are exactly to utilize the advantages of concrete low cost, comprcssive strength are high, rigidity is big, and incite somebody to action
The good profiled sheet of examining tensile behavior is placed on tensile region, replaces tension reinforcement in plate so that bi-material reasonable mechanical, each getting it
Institute, and the structure after combining shows its superiority in terms of stress performance and aggregative indicator, and obtained well
Application.
Profiled sheet+osb plate composite floor at home and abroad also has some applications.For multilamellar steel frame office building or experiment
It is desirable to just relatively be suitable for when the lightweight construction speed of floor is fast using profiled sheet+osb plate in building building, and this steel plate
Profiled sheet can independently be customized according to building occupancy and floow load.The steel fibre mesh sheet concrete slab of U.S.'s exploitation
Sim presses o board composite floor, is to be proposed by dave and ellis et al. earliest, broad scale research is in the nineties in 20th century.
Sim presses the replacement profiled sheet that om laminate compoboard can be more satisfactory, has that intensity is high, cooperative work performance is good, construction party
Just, and the shortcoming overcoming profiled sheet heat-and corrosion-resistant poor performance.In advance should using the sp type of more than 40 years in the U.S.
Power concrete hollow composite floor, it is applied to various buildings, is by the domestic product introducing line development design produced in USA.It
It is not only applicable to brick mix structure, xoncrete structure, be also widely used in steel construction.
Additionally, with the development of construction material and structure type, occur in that steel plate and bamboo wood in composite floor combines shape
Formula.Mainly pass through physics, chemical treatment and machine cut, bamboo wood is made large format, high intensity, the good, dimensionally stable of rigidity
Property good plane or type facestock material, then itself and profiled sheet are grouped together and make composite floor.It is mainly seen in northeast woods
Sparetime university learns the freely-supported beam test that the 6 pieces of floors being combined with bamboo slab rubber for 2007 are carried out with 7520 profiled sheets, inquires within 2009
The composite floor bend test of adhesive bonds and screw strengthening is used between profiled sheet and bamboo slab rubber, and Ningbo of Zhejiang university
The thin-walled die mould steel-bamboo slab rubber composite floor system beam test of research in 2009.Their achievement in research shows this several combination building
Plate is that have very much certain using value, is worth going further to study and inquiring into.
Chinese patent application 201020148864 discloses a kind of Profiled steel plate composite board, it include profiled sheet, sandwich layer,
Protective layer；It also includes screed-coat；Described sandwich layer is located between profiled sheet and protective layer, sandwich layer and profiled sheet and protective layer
Bonding；Described screed-coat is located in the groove inside profiled sheet between profiled sheet and sandwich layer, screed-coat and profiled sheet
With sandwich layer bonding, forming a kind of side has profiled sheet, the profiled sheet sandwich composite board of another side matcoveredn；Described sandwich layer is
Polymer thermal insulative material or mineral wool or straw plate or honeycomb card board, or sandwich layer be lightweight aggregate concrete or light weight sand mortar or
Foam concrete；Or sandwich layer is polymer thermal insulative material or mineral wool or straw plate or honeycomb card board and lightweight aggregate concrete
Or be that macromolecule is protected with light weight sand mortar or with foam concrete interval setting, or the sandwich layer interval setting of different materials, or sandwich layer
Adiabator or mineral wool or straw plate or honeycomb card board and normal concrete interval setting；Described screed-coat is cement mortar
Or pea gravel concreten, or screed-coat is modified cement mortar or pea gravel concreten, or screed-coat is light weight sand mortar or lightweight aggregate
Pea gravel concreten；Described protective layer is cement mortar or pea gravel concreten, or protective layer is to change cement mortar or pea gravel concreten,
Or protective layer is light weight sand mortar or lightweight aggregate pea gravel concreten, or protective layer is cement fibrolite plate or calcium silicate board with microporous；For building
For, floor quality account for the 50%-60% of building deadweight, the increase of deadweight, leads to inertia force to become big, structural seismic is made
Become adverse effect, second in practice it has proved that heavy floor collapse under geological process is the immediate cause causing casualties.Although
The profiled sheet Combined concrete superstructure using at present has greatly reduced floor deadweight, but the presence due to concrete slab, its
Deadweight is still very big.
China is large agricultural country, according to statistics, the annual straw total amount about 7 × 10 producing8T, wherein 60% is rice/wheat straw
Stalk.Existing utilization ways have at present: straw-returning (accounts for 20%)；(biogas, generating, solid fuel bar, account for 15% to the energy
～20%)；Construction material, paper making raw material and various additives etc. (account for 15%).The straw accounting for total amount half is still had not find
Outlet.Every receive season, straw is incinerated or pushes river embankment, constitute to society and environment harm.It may be said that straw people
Make sheet material and can consume agricultural crop straw in a large number and can obtain good economic benefit and social benefit again, be a kind of new building
Assortment class., from heavy and light, mechanics index of physics is good, and particularly MOR and elastic modelling quantity are larger, can be used as light-duty wood for it
Structure cladding plate.
