Abstract
The utility model discloses a large span and load prestress groove-shaped laminated board serving as a basement top board, which is characterized in that the appearance is the groove-shaped board, and a function member is formed by the groove-shaped board and an upper portion laminating layer. Groove-shaped large load can meet the requirement of underground garages, large span can save parking space, a groove-shaped narrow board surface can save manufacture cost and a floor height, and rib height is appropriate, thereby meeting the loading requirement and requirement for air channel opening on the rib without increasing height. A groove-shaped transverse air channel is easy to connect. The large span and load prestress groove-shaped laminated board is used on the basement top board, thereby being capable of shortening construction period, reducing floor height, lowering manufacture cost, saving post net, increasing parking space and improving grade of the underground garages.
Description
Technical field
The utility model belongs to building material field, relates to a kind of reinforced concrete sandwich bearing carrier, and particularly relating to has earthing above a kind of, runs the big load prestressing force of the large span flute profile superimposed sheet on the basement plate top of fire fighting truck.
Background technology
The large span prestressed concrete trough slab is the prefabricated reinforced concrete bearing carrier that beam slab combines, and is made up of roomy panel and two narrow and high ribs.Its panel is horizontal load-carrying members, is again the pressure zone of vertical load-bearing rib.So the large span prestressed concrete trough slab has good structural mechanical property, clear and definite power transmission level, succinct geometry is a kind of large span, big load, big area coverage and both economical bearing carrier of can be made into.
All be 8 meters * 8 meters left and right sides post nets or 8 meters * 6 meters post nets at present in underground garage and the construction of semi-underground garage, not only cost is high, long construction period, and space availability ratio is extremely low, and parking stall quantity is less, and is not attractive in appearance again.
Summary of the invention
The purpose of the utility model is the above problem to present underground garage and semi-underground garage; Thereby provide a kind of big load prestressing force of large span flute profile superimposed sheet to simplify building structure as underground garage plate top; Save the duration, save cost, save the soil; Particularly save excavation area or save the parking stall, improve underground garage and the class that reaches semi-underground garage.
The utility model technical scheme is following: when design and making; Make the main muscle on the superimposed rib of slab of flute profile with prestress wire; Adopt wide little, the form that the similar double T plate of flute profile removes the edge of a wing, both sides of plate, thereby it is high to reduce rib, forms with common net sheet, riblet, embedded part reinforcing bar and concrete for making; For example, be Qd=7T/m in the overlapping layers design load
2Situation under, 16.8 meters of spans of slab, 1.2 meters of plate width; Making the rib height is 0.9 meter; Making post net beam and column with conventional method can be 6 * 16.8m, and further,, 1.2m superimposed bearing capacity wide like: 16.8 meters rib height, 0.9m plate as the big load prestressing force of the large span flute profile superimposed sheet on large span underground garage and semi-underground garage plate top is the trough slab of 6.8T; In 6 meters * 16.8 meters left and right sides beam column nets of post net, be placed on the L beam, L beam girder can flush with the trough slab top basically.
Further, make 0.12～0.17 meter of in-situ layer onboard, and the cementation of fissures, further waterproof, on add earthing and get final product.
Further, at rib of slab internal fan pipeline, then can on rib of slab, punch if desired, the blower fan passway is done at 4 sealings hole, two sides, hole.As open: 1 meter * 0.4 meter two, get out of the way top wing plate pressure zone about 300, get out of the way the above 200mm of prestressed reinforcement district, bottom 2m, about surplus 0.4m.
Further, center on cementation of fissures formation transversal ventilation passage around the junction between two plates between the air blower tube road junction between trough slab, form the longitudinal ventilation passage to the both sides of the chest sealing, and pass through in the reinforcing that can on girder, punch between the longitudinal ventilation passage.
The utility model as the big load prestressing force of the large span flute profile superimposed sheet of basement roof, its span is between 22 meters of 9 meters ∽, the rib height is between 1.5 meters of 0.8 meter ∽, between 1.5 meters of the wide 0.9 meter ∽ of plate, design load is 3 ∽ 9T/m
2Between.
The big load prestressing force of the large span flute profile superimposed sheet as basement roof of the utility model, plate is provided with overlapping layers.
So just realized as the big load prestressing force of the large span flute profile superimposed sheet of basement and semi-underground shed deckhead underground garage with and the application in semi-underground garage as: 1. 16.8 meters span has solved 2 row parking stalls 1 and has drained the corridor problem, than Duoing 10%～20% parking stall or save 10%～20% excavation area with cast-in-place; 2. the L beam has solved a part of floor height reduction problem; Superimposed sheet has solved integrity issues, has formed assembled integral and has not only satisfied the ductility performance of member but also solved the rigidity waterproof problem, and load is between 3～8T; Solved the fire fighting truck problem of going further on 1 meter～2 meters the earthing on top; Flute profile has reduced floor height than double T shape, though reduced 1 times the effective area of the wide 1.2m of plate than 2.4m, has lowered 80 yuan/m of cost on the whole
2About, the fan passage mouth does not still reduce for 1.2m, has formed flute profile again, helps the connection of transversal ventilation mouth on the rib, and floor height leaves enough rib height again and punches from 1.2 meters high 0.9m that reduce to of double T plate.
Description of drawings:
The big load prestressing force of large span flute profile superimposed sheet sketch map as basement roof
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in the figure:
The utility model is the flute profile superimposed sheet, and span is between the 12-22 rice, and the rib height is about 1.2m, and plate hight is about 0.9m, is carried as 3-9T/m
2Between, superimposed trace can be arranged on the plate face or reserve exposed steel bar, plate is provided with overlapping layers.In design and when making, make the main muscle on the superimposed rib of slab of flute profile with prestress wire, adopt wide little, the form that the similar double T plate of flute profile removes the edge of a wing, both sides of plate, thereby it is high to reduce rib, forms with common net sheet, riblet, embedded part reinforcing bar and concrete for making.Water post, L beam with conventional method, break plate on the L beam, make in-situ layer above that, and irritate the plate seam.Make the blower fan pipeline like need, then can be in hole-opening on the position as stated on the rib, and the hole junction forms the transversal ventilation passage around its cementation of fissures between two plates, forms the longitudinal ventilation passage to the both sides of the chest sealing.
