Description

The U-shaped steel of a kind of cold bending thin wall and the composite floor of straw board and manufacture method
Technical field
The present invention relates to the U-shaped steel of a kind of cold bending thin wall and the composite floor of straw board and manufacture method.
Background technology
At present, Profiled Steel Sheet and Concrete Composite Floor is the most prominent in composite floor system, the most 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 utilize steel plate to replace steel bar stress, 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 being greatly developed after new technology by the new technique that introduction is relevant with digestion composite floor later.Sum up Getting up, composite deck slabs utilizes the advantages such as concrete cost is low, comprcssive strength is high, rigidity is big exactly, and incites somebody to action The profiled sheet that examining tensile behavior is good is placed on tensile region, replaces tension reinforcement in plate so that bi-material reasonable mechanical, each get it Structure after institute, and combination shows its superiority in terms of stress performance and aggregative indicator, and has obtained well Application.
Profiled sheet plate composite floor the most also has some to apply.Composite steel framework office building or laboratory building are built In building, it is desirable to be the most relatively suitable for when the lightweight construction speed of floor is fast using profiled sheet+OSB plate, and this steel plate is permissible Profiled sheet is independently customized according to building occupancy and floow load.The steel fibre mesh sheet concrete slab SIMUO of U.S.'s exploitation Board composite floor, is proposed by Dave and Ellis et al. the earliest, and broad scale research is in the nineties in 20th century.SIMUOM Laminate compoboard can be more satisfactory replacement profiled sheet, have that intensity is high, cooperative work performance is good, easy construction, and The shortcoming overcoming profiled sheet heat-and corrosion-resistant poor performance.For having used the SP type prestressed concrete of more than 40 year in the U.S. Hollow combination floor, it is applicable to various building, is by the product of domestic introduction line development produced in USA design.It is not only applied In brick mix structure, xoncrete structure, also it is widely used in steel construction.
Additionally, along with construction material and the development of structure type, composite floor occurs in that the combination shape of steel plate and bamboo wood Formula.Mainly by physics, chemical treatment and machine cut, bamboo wood is made large format, high intensity, good rigidly, dimensionally stable Property good plane or profile material, then itself and profiled sheet are grouped together and make composite floor.It is mainly seen in northeast woods The freely-supported beam test carried out with 6 pieces of floors of 7520 profiled sheets with bamboo slab rubber combination in 2007 is learned by sparetime university, within 2009, inquires into The composite floor bend test of agent bonding and screw strengthening, and Ningbo of Zhejiang university is sticked with glue between profiled sheet and bamboo slab rubber Thin-wall U-shaped steel-bamboo slab rubber composite floor system the beam test of research in 2009.Their achievement in research shows this several composite floors It is that there is certain using value very much, is worth going research further 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 between profiled sheet and protective layer, sandwich layer and profiled sheet and protective layer Bonding;In groove inside described screed-coat profiled sheet between profiled sheet and sandwich layer, screed-coat and profiled sheet Bonding with sandwich layer, 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 with light weight sand mortar or and foam concrete interval arrange, or different materials sandwich layer interval arrange, or sandwich layer be macromolecule protect Adiabator or mineral wool or straw plate or honeycomb card board and normal concrete interval are arranged;Described screed-coat is cement mortar Or pea gravel concreten, 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 modify-water 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, causes inertia force to become big, makes structural seismic One-tenth adverse effect, second, in practice it has proved that floor collapse heavy under geological process is the immediate cause caused casualties.Although Currently used profiled sheet Combined concrete superstructure has greatly reduced floor deadweight, but due to the existence of concrete slab, its Conduct oneself with dignity the biggest.
China is large agricultural country, according to statistics, and the annual straw total amount about 7 × 10 produced8T, wherein 60% is rice/wheat straw Stalk.Current existing utilization ways has: 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. (accounting for 15%).The straw accounting for total amount half is still had not find Outlet.Every receiving season, straw is incinerated or pushes river embankment, constitutes society and the harm of environment.It may be said that straw people Make sheet material can consume agricultural crop straw in a large number and can obtain again good economic benefit and social benefit, be a kind of novel building Assortment class.It is from heavy and light, and mechanics index of physics is good, and particularly MOR and elastic modelling quantity is relatively big, can be used as light-duty wood Structure cladding plate.
