Description
Technical field
The present invention relates to a kind of high performance structures composite floor for building.
Background technology
In recent years, along with the development of highrise building, Composite Slab with Metal Deck is day by day promoted and applies.So-called composite floor, is to make full use of steel and concrete material and design feature to combine and become a whole and cooperative a kind of form of structure, and using at present more is profiled steel sheet combination floor.Profiled steel sheet combination floor is a kind of very rational form of structure, it can be by its residing position of each building block and feature, give full play to steel tension and the good advantage of concrete anti-compression performance, and there is good anti-seismic performance, workability, during this structure is widely used in building both at home and abroad at present.Compare with ordinary reinforced concrete floor, profiled steel sheet combination floor (claiming again floor support plate) possesses following advantage: floor support plate profiled sheet can be used as the permanent template of cast-in-situ concrete, so just save the operation such as installation and removal template in construction, thereby saved time and labour; After floor support plate profiled sheet installs, can be used as operation platform and use, simultaneously owing to needn't using temporary supporting, also do not affect the work of lower one deck construction plane; The end muscle that floor support plate profiled sheet can be used as floor is used, and has reduced the workload of installing plate muscle; Adopt floor support plate profiled sheet can reduce floorslab concrete consumption, the floor deadweight of minimizing can reduce again the size on beam, post and basis accordingly, has improved the overall performance of structure; The flank of floor support plate profiled sheet can be placed hydroelectric line, thereby deck and pipeline are integrated, and has indirectly strengthened floor height or has reduced building height, to architectural design, brings flexibility; In the construction stage, the continuously lateral that floor support plate profiled sheet can be used as girder steel supports, and has improved the monolithic stability bearing capacity of girder steel; In operational phase, the resistance to overturning of girder steel and the local stability of top flange have been improved.Above-mentioned advantage can shorten the engineering time to a large extent, reduces the duration, obtains good economic benefit.
Mostly existing profiled sheet floor support plate is the contour plate through the moulding of multi-pass integral roll extrusion, adopts galvanized steel plain sheet to make more, is provided with in the middle type rib to strengthen the stability of floor support plate and concrete bond strength and then enhancing composite floor structure.Existing type rib is divided into closed type rib and open-type rib, and open-type rib bottom has larger opening, and opening causes type rib inside directly to contact with surrounding air; Even closed type rib floor support plate, although the type rib of its design often by vertical vertical rib closing together, but because concrete gravity on floor support plate presses down, easily cause the elastic deformation of steel, easily cause vertical vertical rib closely closing there is opening together, opening causes type rib inside directly to contact with surrounding air; Therefore, no matter be the floor support plate of closed type rib and open-type rib, capital directly contacts with surrounding air, under long-term behavior, chlorion in atmosphere, oxygen and moisture content can produce corrosion to floor support plate even makes floor support plate get rusty, corrosion meeting should affect floor support plate as the effect used of end muscle, make its life-span reduction, the structural stability of final impact building, make it can not reach design life, especially even more serious at the high humidities such as coastal area, this kind, area situation that Acidity of Aikalinity is high, have a strong impact on safety and the application life of building.In addition, no matter be the floor support plate of closed type rib and open-type rib, capital directly contacts with surrounding air, once breaking out of fire, the bottom of floor support plate can with naked light and high temperature air thermal contact conductance, steel work can intensity sharply decline along with the rising of temperature, yield strength reduces, modulus of elasticity obviously declines, and then can affect temperature deformation and stress distribution subsequently, the underlaying surface temperature of floor support plate can reach 1200 ℃ at short notice, the type rib at vertical vertical rib top reaches 400 ℃, the structural stability of final impact building, make it can not reach design life, have a strong impact on safety and the application life of building.In order to prevent that fire from damaging to steel work, general fireproof paint and the fire-proof shield of adopting processed steel work, but above-mentioned processing is not only taken a lot of work, expense is expected but also environment is had to pollution, even at present for the processing of generally prevent fires of the special steel work of this class of floor support plate, so there is potential safety hazard.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, provides that a kind of corrosion resistance is good, weather resistance is good, long service life, the high performance structures composite floor that fire-resistant and weather resistance is superior.
