Description
Technical field
The utility model relates to a kind of novel ripple arch bar and the combined cylindrical surface arched shell of steel concrete, belongs to technical field of structural engineering.
Technical background
At the fifties, steel concrete cylinder arch shell is widely used as building roof engineering, but along with the appearance of new material and the progress of construction technology, this clean steel reinforced concrete cylinder arch shell is owing to must adopt the supporting template fluid concrete in work progress, it is very big to consume a large amount of mould materials and formwork engineering quantity, take a lot of work and time-consuming, in engineering is used, progressively be eliminated; As the ripple Arch Bar Structure of roof structure, generally more application is arranged in the nineties, but because itself bearing capacity is low, and it is more to collapse, Existing Buildings remains little under heavy snow and hurricane effect as storage class roofworks.Because construction technologies such as insulation are extremely difficult, be difficult to apply in the building structure that grade is arranged simultaneously, can only use as temporary structure.
Desire is built a kind of high drag structure that can resist earthquake, guided missile and the power of nuclear explosion, can make the preventive works of convenient construction under the very poor situation of condition in the open air again, up to the present, and this type of technology of not appearing in the newspapers as yet.
Based on this, the utility model proposes a kind of novel built-up arch shell structure, it is combined by ripple Arch Bar Structure and reinforced concrete structure.It has solved the problem of following two aspects: one, the shortcoming that this combined cylindrical surface arched shell structure has overcome clean steel reinforced concrete cylinder arch shell and ripple Arch Bar Structure when using separately, not only improved the ability of its opposing external load after its combination, greatly facilitate construction again, be fit to very much be applied to preventive works.Its two, the supporting template when the ripple Arch Bar Structure is not only built as structure of reinforced concrete in work progress, and participate in stressedly with the one piece after concrete setting had both improved the intensity and the bearing capacity of combining structure, had saved construction cost again.Therefore,, can bear bigger impact load, play effects such as protection visual plant as preventive works.
The utility model content
Ripple arch bar that the utility model proposes and the combined cylindrical surface arched shell of steel concrete, its purpose are to provide a kind of novel built-up arch shell structure to be used for preventive works, and its characteristics are to combine the advantage of two kinds of structures, and easy construction, save cost.
Ripple arch bar that the utility model proposes and the combined cylindrical surface arched shell of steel concrete, it is characterized in that, described combined cylindrical surface arched shell structure by ripple arch bar 1 with on cover the reinforced concrete arch shell and form, described ripple arch bar 1 is by the arch bar of ripple arch bar undercut 5 formation any widths; Described longitudinal reinforcement 2, stirrup 4 and transverse reinforcement 3 form the arch cage of reinforcement, and 5 places connect by spot welding in the undercut of ripple arch bar; Described ripple arch bar 1 and cage of reinforcement form the arch template system of concreting; Concreting in the described arch template system is treated to form ripple arch bar-steel concrete combined cylindrical surface arched shell structure after the concrete setting.
In combinations thereof cylinder arch shell, described ripple arch bar 1 forms by hot rolled steel sheet is rolling.
In combinations thereof cylinder arch shell, the thickness of described reinforced concrete arch shell changes according to requirement of shelter.
In combinations thereof cylinder arch shell, spot welding is connected the transverse reinforcement 3 of described cage of reinforcement in the intersection with ripple arch bar 1.
The combined cylindrical surface arched shell of ripple arch bar-steel concrete that the utility model provides, overall performance is good, and cost is saved in easy construction, and have very high whole drag and bear local ability of hitting, be a kind of outstanding preventive works form of structure.
Description of drawings
Fig. 1 is the utility model ripple arch bar-steel concrete combined cylindrical surface arched shell structure schematic diagram.
Fig. 2 is the utility model ripple arch bar-steel concrete combined cylindrical surface arched shell structure schematic cross-section.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
Shown in Fig. 1～2,1-ripple arch bar 2-longitudinal reinforcement 3-transverse reinforcement 4-stirrup 5-ripple arch bar undercut 6-concrete.
Ripple arch bar of the present utility model-steel concrete combined cylindrical surface arched shell structure, by ripple arch bar 1 with on cover the reinforced concrete arch shell and form.Ripple arch bar 1 can form the arch bar of any width by undercut 5.Longitudinal reinforcement 2, stirrup 4 and transverse reinforcement form the arch cage of reinforcement, and 5 places connect by spot welding in the undercut of ripple arch bar, and ripple arch bar 1 and cage of reinforcement can form the arch template system of concreting thus.Concreting is treated just to form ripple arch bar-steel concrete combined cylindrical surface arched shell structure after the concrete setting again.
Theoretical and experiment showed, that this combined cylindrical surface arched shell structure has following obvious advantage:
Described combined cylindrical surface arched shell by the ripple arch bar and on cover the reinforced concrete arch shell and form; Described ripple arch bar forms by hot rolled steel sheet is rolling; Described reinforced concrete arch shell is made up of the concrete and rebar skeleton, and the thickness of reinforced concrete arch shell can change according to requirement of shelter; Spot welding is connected the transverse steel of described framework of steel reinforcement in the intersection with the ripple arch bar.
In combinations thereof cylinder arch shell structure, the shortcoming of participating in two kinds of versions of combination is overcome in combining structure, and the two cooperative bearing, the concrete that compression capability is outstanding places top, and the superior ripple arch bar of tension ability places the bottom, the effect of reinforcing bar of having held concurrently, each several part can both be given full play to advantage separately like this.
In combinations thereof cylinder arch shell structure, spot welding links to each other the transverse steel of framework of steel reinforcement in the intersection with the ripple arch bar, and behind casting concrete, framework of steel reinforcement and ripple arch bar just form stressed integral body like this, use as safeguard structure, can more effectively resist impact load to structural damage.
In combinations thereof cylinder arch shell structure, the thickness of reinforced concrete arch shell can change with degree of protection. Framework of steel reinforcement and ripple arch bar can form one can bear the supporting member of water-bearing concreae deadweight and construction loads in the construction stage, rather than is born by the ripple arch bar merely, can effectively solve the problem of corrugated arch panel stiffness deficiency.
In combinations thereof cylinder arch shell structure, it is characterized in that the ripple arch bar uses as supporting template in work progress, in use then stressed as the primary structure member participation, the particularly suitable safeguard structure need to carry out the environment of field construction.
In combinations thereof cylinder arch shell structure, it is characterized in that, by the splicing of ripple arch bar, can form the domes of various different spans and rise. Splicing between each cell board needs special the making, prevents that the interlock between Impact Load bottom arch bar and arch bar from destroying, and causes the broken concrete rear tamper protection thing that drops.
