Technical solution of the present invention is as follows:
The large load prestressing force of large span groove-shaped laminated board as basement roof of the present invention, comprise trough bottom plate and overlapping layers two parts, span is large, it is high to carry, wide little, the low rib of plate is high, concrete span is between 22 meters of 9 meters of ∽, rib is high between 1.5 meters of 0.8 meter of ∽, between 1.5 meters of the wide 0.9 meter of ∽ of plate, design load is 3 ∽ 9T/m
2between, described overlapping layers is located at trough bottom plate top.
Further, the large load prestressing force of the large span groove-shaped laminated board as basement roof of the present invention, leaves on trough bottom plate plate face and makes superimposed trace or the exposed steel bar that overlapping layers is used.
Further again, the large load prestressing force of the large span groove-shaped laminated board as basement roof of the present invention, the leaving certain gaps uncovered by the economic plan of 4 jiaos of its both sides of the chest bottoms.
The beneficial effect that the present invention obtains is: (1) compared with prior art, has saved the excavation area of 10-20%; (2) reduce floor height, saved cost, also retained enough perforate height simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation removing behind 4 jiaos of both sides of the chest bottoms.
In figure: 1, rib, 2, breach.
The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in the figure:
Fig. 1 is the base plate of groove-shaped laminated board, and span is 16.8m, and plate is wide is 1.2m, and rib height is 0.9m, is carried as 7T/m
2, on plate face, have superimposed trace or reserved exposed steel bar.In design and while making, with prestress wire, make the main muscle on groove-shaped laminated board rib, adopt wide little, the form that the similar T plate of flute profile removes the edge of a wing, both sides of plate, thereby it is high to reduce rib, with common net sheet, riblet, embedded part reinforcing bar and concrete for making, forms.By conventional method, water post, L beam, plate is broken on the low beam of L beam.Fig. 2 is for removing grooved superimposed sheet behind 4 jiaos of both sides of the chest bottoms, and 1 time breach of the superimposed rib of slab of grooved 2 coincide with the low beam of L beam, thereby make deck-molding increase building object height, is 0, makes in-situ layer thereon, and fills with plate seam.As need are made Fan pipeline, can hole-opening on rib 1, and between two plates, hole junction, around its cementation of fissures, forms transversal ventilation passage, and both sides of the chest 1 sealing is formed to longitudinal ventilation passage.
Know-why of the present invention is as follows:
When design and making, with prestress wire, make the main muscle on groove-shaped laminated board rib, adopt wide little, the form that the similar T plate of flute profile removes the edge of a wing, both sides of plate, thereby it is high to reduce rib, with common net sheet, riblet, embedded part reinforcing bar and concrete for making, form, for example, in overlapping layers design load, be Qd=7T/m
2situation under, 16.8 meters of spans of slab, 1.2 meters of plate width, making rib high is 0.9 meter, by conventional method, making post net beam and column can be 6 * 16.8m, further, as the large load prestressing force of the large span groove-shaped laminated board on Large Span Underground garage and reduction semi-underground garage plate top as: 16.8 meters of ribs are high, 0.9m plate is wide, the trough slab that the superimposed bearing capacity of 1.2m is 6.8T, in 6 meters * 16.8 meters left and right beam column nets of post net, be placed on L beam, L beam girder can flush substantially with trough slab top, under lower channel template, breach and the low beam of L beam coincide, thereby make L deck-molding not increase depth of building, save floor height.
