Abstract
The utility model belongs to the field of a steel-concrete combination structure. Especially, the utility model relates to a corrugated steel web plate of a corrugated steel web plate pre-stressed concrete combination box beam structure. The corrugated steel plate is provided with a reinforcing rib on a folded plate along height direction. The reinforcing rib is a hollow structure which is any geometric shape, such as circular arced structure and rectangle. The stability of a required corrugated steel web plate can be obtained by adjusting the size of an annular reinforcing rib. After concrete is poured in the reinforcing rib, a steel-concrete combination corrugated steel web plate structure is formed. Compared with the corrugated steel web plate without a reinforcing rib, the buckling stability is very high. The corrugated steel plate can satisfy the stability requirement of the corrugated steel web plate by a large-section corrugated steel web plate box beam structure.
Description
Technical field
The invention belongs to the steel-concrete combined structure field, relate in particular to the corrugated sheet steel of corrugated sheet steel prestressed concrete combined box beam structure.
Background technology
Constantly increase along with striding corrugated sheet steel PC combined box beam spanning footpath, footpath greatly, the size of case beam section also increases thereupon, and corrugated sheet steel becomes a key issue that needs to be resolved hurrily as the flexing stability of steel web.For the case beam of big section, large section,, can adopt many box-shapeds formula or one case multicell structure to handle in the deck-siding direction; In the deck-molding direction, the practices well that adopts is to adopt inner lining concrete to constitute the requirement that steel reinforced concrete compoboard structure satisfies stability at present.In super-large span Wavelike steel webplate PC composite beam bridge, the aspect ratio of Wavelike steel webplate is bigger, stability problem is more outstanding, the stabilizing effect that improves Wavelike steel webplate by increase thickness of slab and wave height is limited, as adopt the method for concrete lining, can cause beam heavily to increase again, make Wavelike steel webplate PC combined box beam lose lightweight advantage.Adopting ribbed stiffener is a kind of effective measures that improve the stability of Wavelike steel webplate.
Summary of the invention
In order to solve the deficiencies in the prior art, the utility model provides a kind of corrugated sheet steel with ribs.
Said a kind of corrugated sheet steel is provided with ribs along short transverse on flap.
Above-mentioned said ribs can be hollow structure.The cross section of ribs can be a random geometry, from worker's technological angle, is preferably circular arc, rectangle or triangle.
A kind of scheme preferably is also to be perfused with concrete in the cavity of ribs.
Ribs in the utility model has following beneficial effect to corrugated sheet steel:
(1) ribs is easy to processing, is welded on the corrugated sheet steel, does not need special-purpose welding equipment, and is easy to process.
(2) ribs is the hollow structure of random geometries such as circular arc, rectangle, can obtain the stability of required corrugated sheet steel by adjusting the size of annular ribs.
(3) can fluid concrete in the ribbed stiffener, form steel-concrete combined waveform steel web structure, what flexing stability will be than the Wavelike steel webplate that does not have ribs is stable much higher.
(4) can satisfy of the requirement of tall and big cross section waveform steel web box girder structure to the Wavelike steel webplate stability.
Description of drawings
Fig. 1. 3 dimension organigrams of annular ribs Wavelike steel webplate;
Fig. 2 can concrete annular ribs Wavelike steel webplate 3 the dimension organigrams.
Wherein: 1-corrugated sheet steel, 2-ribs, the concrete in the 3-annular ribs.
The specific embodiment
Followingly principle of the present invention and technical scheme are described further with reference to accompanying drawing.
Embodiment 1
A kind of corrugated sheet steel (Fig. 1) with ribs, it is by corrugated sheet steel 1, and the annular ribs 2 that corrugated sheet steel flap upper edge height is provided with constitutes, ribs can be solid also can be hollow structure, mode is preferably, and ribs is a hollow structure, therein fluid concrete 3(Fig. 2).
In another embodiment, formed steel-concrete combined waveform steel web structure, flexing stability will be than the Wavelike steel webplate that does not have ribs stable much higher, can satisfy of the requirement of tall and big cross section waveform steel web box girder structure to the Wavelike steel webplate stability.
The cross section of ribs can have any shape, and strengthens size and also adjusts, and those skilled in the art can obtain the stability of required Wavelike steel webplate by this adjustment.
Claims (4)
1. a corrugated sheet steel is characterized in that being provided with ribs in flap upper edge short transverse.
2. corrugated sheet steel according to claim 1 is characterized in that, said ribs is a hollow structure.
3. corrugated sheet steel according to claim 2 is characterized in that, the cross section of ribs is circular arc, rectangle or triangle.
4. corrugated sheet steel according to claim 2 is characterized in that, is perfused with concrete in the said ribs.
