Abstract
The invention discloses a long-span prestressed concrete-filled steel tubular slab-frame structure garage slab which is a combined member. The combined member adopts steel as a lower part tension component in a prestressed beam slab, and adopts a high-strength concrete filled steel tube as a pressed component in the middle upper part of a corresponding rib, and the lower part tension component and the pressed component jointly form a slab-frame stressed structure member. The garage slab has the characteristics that a stress mode, mainly a bending mode, of the prestressed beam slab is changed, so that the cross section height can be reduced greatly. In addition, the compressive capacity of an upper part concrete filled steel tube chord member is increased by 3-4 times than that of normal concrete, so that the arch chord member can have smaller cross section, and the structural dead-weight and the construction cost can be reduced correspondingly.
Description
Art: building materials field
Background technology:
It is large that large-span prestressed groove-shaped laminated board is used for underground garage span, parking stall is many, attractive in appearance, the duration fast but 1, floor height is large, the use of large-span prestressed plate in underground garage is mainly limited to floor height, the cost of the high inevitable plate of floor height own is high, and it is dark to cut the earth, its earthwork or explosion, steel water proof exterior wall expense are large, and especially underground water anti-floating dispose costly, 2, effective area is little, and relative cost is larger.As 16.6 meters of groove type plates of design load every square metre 53,000 Ns, rib is up to 1.02 meters, add that the supporting part height of supporting beam is at about 0.5 meter, it is about 1.6 meters, and general arch without beam is if honeycomb core height is at about 0.6 meter, differ too large, and plate is wide only has 1.2 meters of effective areas too little, if plate is wide at 2.5 meters, rib is high need at about 1.7 meters, not only the cost of plate own is high far beyond economic rib, outside cannot using, underground garage often digs dark 1 meter of anti-floating dispose expense then increasing water, steel water proof exterior wall expense, earth excavation or blast cost are then at 250-450 unit/m
2left and right, cannot realize undoubtedly, and bending component cannot open large hole and trimming bar concrete disposal more complicated.
Summary of the invention: the invention provides a kind of large-span prestressed concrete filled steel tube framed plate structure garage plate for basement roof to solve the problem for the problems referred to above: as above 16.6 meters of groove type plates of design load every square metre 53,000 Ns, the following rib in plate face is high 0.5 meter, plate is wide reaches 2.5 meters, effective area is too large, total cost reduces about twice greatly, and floor height reduces, plate becomes stretch bending component by bending component below face, larger ventilation and lighting hole can be opened, on plate, arc concrete filled steel tube peak is about about 1.2 meters, cost is limited, effective area is large, square cost reduces by half again above, but it is stretched in earthing, disregard floor height, substantially reduce the earthwork and dig dark cost and cost own, improve prefabricated and transport benefits, and thickness of slab is 0.2 meter, not only meet structural requirement but also meet rigid waterproofing requirement.
A kind of large-span prestressed concrete filled steel tube framed plate structure garage plate, comprise large-span prestressed double-T steel tube-concrete composite structure garage plate, large-span prestressed single teeprofile concrete combined structure garage plate large-span prestressed channel-section steel pipe concrete combination structure garage plate, large-span prestressed F shape (large-span prestressed T plate removes a side wing edge) steel tube-concrete composite structure garage plate, it is characterized in that: this plate is combined member, configure prestress steel in prestressed girder rib of slab used to make lower tension parts and adopt high strength steel pipe concrete jointly to form as compressed member on corresponding rib of slab top, like this, change restressed beam slab based on by curved force modes, therefore significantly can reduce depth of section or increase the wide increase effective area of plate, its compression load force rate ordinary concrete of upper steel pipe concrete chord member improves 3-4 doubly simultaneously, thus chord of arch bar can use less steel tube section, and then correspondingly can alleviate dead load and construction costs, increase bearing capacity, increase the wide and effective area of plate, reduce rib height under plate face, and plate face upper steel pipe concrete is stretched among the earthing of top, disregard structure height, thus significantly reduce floor height, save cost, and for stretch bending component can open large hole below plate face, further, concrete filled steel tube is arch or fold-line-shaped, and straight shape then needs to add brace in this way, further, also can be changed into flat bar to reduce the height of chord of arch bar for circular pin in the
