Description
Technical field
The present invention relates to a kind of novel ripple arch bar, steel bar girder and concrete combination arch shell structure, belong to technical field of structural engineering.
Technical background
Reinforced concrete arch shell and steel work arch are very general in civil engineering is used, but it has following shortcoming: (1) reinforced concrete arch shell must adopt the supporting template system in building course, it is very big to consume a large amount of mould materials and formwork engineering quantity, take a lot of work and time-consuming, the structure building process cost is improved, in civil engineering, progressively be eliminated; (2) no matter steel arch in real abdomen formula cross section because the member web will produce bigger plastic strain and could form arc, adopts cold working or hot-working when making moulding, and its forming process is extremely difficult; (3) desire is built the preventive works that the weight bearing power that withstands shocks is stronger, and pure concrete arch shell of reinforcing bar or pure steel structure arch all can not be finished this mission.Although the former has bigger rigidity, shortage ductility is easy to brittle failure and comes off, and injures protected visual plant.Although the latter has good ductility, still need to fill other structural meterials between the steel arch, thereby bearing capacity is low can't bear bigger impact load, and anti-local assault ability, can not satisfy functional requirement.
In order to overcome the above-mentioned shortcoming of reinforced concrete arch shell and steel work arch, the present invention proposes a kind of novel built-up arch shell structure, it is combined by ripple Arch Bar Structure, steel bar girder arch structure and concrete structure, sees shown in Figure 1.Template when the ripple Arch Bar Structure is not only built as its concrete structure construction, and after concrete setting with one piece participation work, both made things convenient for construction, also saved construction cost, also improved simultaneously the total bearing capacity of structure; The steel bar girder arch is welded into an overall structure with the ripple arch bar, when concreting, become its strong supporting template, utilize the ripple arch bar as the supporting template in the work progress than separately, it can bear bigger concreting thickness and be applied to bigger span, simultaneously after concrete pouring is finished, steel bar girder arch, ripple arch bar and the formed built-up arch shell structure of concrete, higher with the bearing capacity of the formed built-up arch shell structure of steel concrete than ripple arch bar, the space of leap is bigger.The great advantage of this built-up arch shell structure is to bear bigger integral body and local assault load, and is used for the bigger preventive works of span.
Summary of the invention
The object of the present invention is to provide a kind of novel built-up arch shell structure, be used for preventive works, the bearing capacity height, and cost is saved in easy construction.
Ripple arch bar, steel bar girder and concrete combination arch shell structure that the present invention proposes is characterized in that described built-up arch shell structure is made up of ripple arch bar 1, steel bar girder and concrete; Described steel bar girder is made up of the longitudinal rib 2 that winds up, lower edge longitudinal rib 3, abdomen muscle 4, web member 6 and transverse reinforcement 5; Described ripple arch bar 1 is combined into the arch shell of random length by ripple arch bar undercut 7; The described longitudinal rib 2 that winds up, lower edge longitudinal rib 3 and abdomen muscle 4 by with tilting web member 6 welding, form the steel bar girder arch; Described transverse reinforcement 5 welds or colligation with the steel bar girder arch, and connects by spot welding at ripple arch bar interlock 7 places; Described ripple arch bar 1 and the steel bar girder arch template system that overarches, concreting again, treat concrete setting after, just form described ripple arch bar, steel bar girder and concrete combination arch shell structure.
In stating the built-up arch shell structure, described ripple arch bar 1 adopts that hot rolled steel sheet is rolling to form.
In stating the built-up arch shell structure, the thickness of described reinforced concrete arch shell changes according to requirement of shelter.
In stating the built-up arch shell structure, it is the fine steel rib of 3～6mm that described web member 6 adopts diameter, is connected by spot welding with described longitudinal reinforcement.
Ripple arch bar provided by the invention, steel bar girder and concrete combination arch shell structure, overall performance is good, the bearing capacity height, make things convenient for field construction, saving cost, have very high whole drag and bear local ability of hitting, is a kind of outstanding preventive works form of structure.
Description of drawings
Fig. 1 is ripple arch bar of the present invention, steel bar girder and concrete combination arch shell structure schematic diagram.
Fig. 2 is ripple arch bar of the present invention, steel bar girder and concrete combination arch shell structure schematic cross-section.
The specific embodiment
The present invention is described in detail below in conjunction with accompanying drawing.
Shown in Fig. 1～2, the 1-ripple arch bar 2-longitudinal rib 3-lower edge longitudinal rib 4-abdomen muscle 5-transverse reinforcement 6-web member 7-ripple arch bar undercut of winding up.
Ripple arch bar of the present invention, steel bar girder arch and concrete combination arch shell structure are made up of ripple arch bar 1, steel bar girder and concrete.The ripple arch bar is by the arch shell of undercut 7 one-tenth random lengths capable of being combined, the longitudinal rib 2 that winds up, lower edge longitudinal rib 3 and abdomen muscle by with tilting web member welding, can form the steel bar girder arch.Transverse reinforcement and steel bar girder arch weld (or colligation), and couple together by spot welding at ripple arch bar interlock 7 places.So, ripple arch bar 1 can with the steel bar girder arch template system that overarches.Concreting again, treat concrete setting after, just form ripple arch bar, steel bar girder and concrete combination arch shell structure.
Theoretical and experiment showed, that this combined cylindrical surface arched shell structure has following tangible advantage:
The shortcoming of participating in two kinds of form of structure of combination is overcome in combining structure, and the two cooperative bearing.The steel concrete that compression capability is outstanding places top, and the superior profiled sheet plate of tension ability places the bottom, and each several part can both be given full play to advantage separately like this.
Stressed rationally by the steel bar girder of reinforcement fabrication, its processing can directly be finished in factory, avoids on-the-spot assembling reinforcement, can accelerate speed of application, and is convenient and swift.
Steel bar girder arch and profiled sheet just form stressed integral body behind concreting, use as safeguard structure, can more effectively resist impact load to structural damage.
The steel bar girder arch can be used as the formwork system use with the overall structure that profiled sheet forms before concreting, cost and the expense that can save a large amount of template supports like this also can satisfy the specific demand of safeguard structure needs operation in the open air especially.
Provide rigidity by the steel bar girder arch jointly with the ripple arch bar in work progress, and be not only the ripple arch bar, this has solved the thin excessively more weak problem of rigidity that causes of ripple arch bar, can reduce the consumption of ripple arch bar, is applicable to the structure that span is bigger.
By the splicing of ripple arch bar, can form the domes of various different spans and rise.Splicing between each unit board needs special the making, prevents that the interlock between impact load effect lower steel plate from destroying, and causes the broken concrete back tamper protection thing that drops.
