Description
Technical field
The utility model belongs to building field, particularly relates to a kind of reinforced concrete structure of large span, is steel concrete hollow sandwich mesh cylinder arch and latticed shell structure.
Background technology
As everyone knows, in long span flat slab tendon concrete structure, height and the scale of construction of concrete girder are larger, generally, can consider concrete girder to apply prestressing force or concrete girder is made to girder with rolled steel section en cased in concrete, so not only construction trouble, cost is also relatively high.Need a kind of new structure, be adapted at compared with using in the reinforced concrete structure of large span, and there is good degree of safety and good technical-economic index.
Summary of the invention
The purpose of this utility model is to provide a kind of steel concrete hollow sandwich mesh cylinder arch and latticed shell structure, this structure economics is reliable and pattern is attractive in appearance, impression quality and the unmanageable difficult problem of geometric shape in precipitous concreting have been solved, be applicable to large space, large-span concrete roofing and top cover within the scope of 22～48m, be specially adapted to the public works such as sport category venue, concert hall, cinema.
The purpose of this utility model and solve its technical problem underlying and realize by the following technical solutions: a kind of large-span steel-reinforced concrete structure, by left support abutment 1, right support abutment 2, lower rib grid 3, place, crosspoint shear connector 4, upper rib grid 5 and panel 6 form, left support abutment 1, right support abutment 2 supports lower rib grid 3 and upper rib grid 5, lower rib grid 3 and upper rib grid 5 are open-spandrel sandwich board, between lower rib grid 3 and upper rib grid 5, there is place, crosspoint shear connector 4, upper rib grid 5 has panel 6 above, open-spandrel sandwich board is hollow sandwich mesh cylinder arch, descend rib grid 3 and upper rib grid 5 to be deformed into curve form, the impact of shear strain is less, the stressed form for arch of lower rib grid 3 and upper rib grid 5, i.e. the effect of main Axial Compression Loads power, the moment of flexure of lower rib grid 3, place, crosspoint shear connector 4, upper rib grid 5 is less.
The Sandwich Plates overall height that hollow sandwich arch is divided is 650CM.
Upper rib and lower rib concrete cross section are 350CM * 180CM.
The utility model compared with prior art has obvious advantage and beneficial effect.From above technical scheme, the utlity model has following characteristics:
1, steel concrete hollow sandwich mesh cylinder arch and latticed shell structure are the building structure that a kind of economy is reliable and pattern is attractive in appearance.
2, passed through concrete parameters design, the time of building is controlled, antitrickle is processed, the measure such as maintenance comprehensively, has solved impression quality and the unmanageable difficult problem of geometric shape in precipitous concreting.
3, the application of virtual technology, has met the requirement of measurement and positioning between Quick air, has improved setting accuracy and operating efficiency.
4, in practice of construction, adopt " twice in-situ casting monolithic construction method ", first floor is built lower ribbed arch type girt strip, and the second layer is built shear connector, upper rib arch beam and arch form plate.
The utility model is applicable to large space, large-span concrete roofing and the top cover within the scope of 22～48m, is specially adapted to the public works such as sport category venue, concert hall, cinema.

The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, a kind of large-span steel-reinforced concrete structure specific embodiment, structure, feature and effect thereof to according to the utility model proposes, be described in detail as follows.
Referring to Fig. 1-7, a kind of large-span steel-reinforced concrete structure, by left support abutment 1, right support abutment 2, lower rib grid 3, place, crosspoint shear connector 4, upper rib grid 5 and panel 6, formed, left support abutment 1, right support abutment 2 support lower rib grid 3 and upper rib grid 5, lower rib grid 3 and upper rib grid 5 are open-spandrel sandwich board, between lower rib grid 3 and upper rib grid 5, there is place, crosspoint shear connector 4, upper rib grid 5 has panel 6 above, open-spandrel sandwich board is hollow sandwich mesh cylinder arch, descend rib grid 3 and upper rib grid 5 to be deformed into curve form, the impact of shear strain is less; The stressed form for arch of lower rib grid 3 and upper rib grid 5, i.e. the effect of main Axial Compression Loads power, the moment of flexure of lower rib grid 3, place, crosspoint shear connector 4, upper rib grid 5 is less.
The Sandwich Plates overall height that hollow sandwich arch is divided is 650CM.
Upper rib and lower rib concrete cross section are 350CM * 180CM.
The utility model economy is reliable and pattern is attractive in appearance, impression quality and the unmanageable difficult problem of geometric shape in precipitous concreting have been solved, be applicable to large space, large-span concrete roofing and top cover within the scope of 22～48m, be specially adapted to the public works such as sport category venue, concert hall, cinema.
The above, it is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, any technical solutions of the utility model content that do not depart from, any simple modification, equivalent variations and the modification above embodiment done according to technical spirit of the present utility model, all still belong in the scope of technical solutions of the utility model.
