Abstract
A kind of high-strength wave steel web box girder bridge plate, it includes top plate（1）And bottom plate（2）, it is characterized in that described top plate（1）And bottom plate（2）Both sides between pass through Wavelike steel webplate（3）It is connected, described Wavelike steel webplate（3）Two ends with being embedded in top plate（1）And bottom plate（2）Connector be connected, described connector is by flange plate（4）, be vertically welded in flange plate（4）Go up and be held into the nail of the weldering in concrete（5）, positioned at weldering nail between structural steel connecting member（6）Run through integral perforated rebar with by structural steel connecting member（7）Composition.The bonding strength of corrugated steel web and roof and floor of the present utility model is high, simple in construction, fundamentally improves the stressing conditions of box girder with corrugated steel webs bridge plate.
Description
Technical field
The utility model is related to a kind of road and bridge technology, especially a kind of hardened structure of box beam cross-bridges, specifically
A kind of high-strength wave steel web box girder bridge plate.
Background technology
At present, prestressed reinforced concrete continuous box girder generally existing cracking in webs, dead load be big, prestressing force efficiency
It is low, therefore Bridge Design teacher introduces the theory that Wavelike steel webplate replaces concrete web.Corrugated steel web plate composite box girder bridge is certainly
10%~25% is reduced again, and the gauffer effect of corrugated sheet steel substantially increases prestressing force efficiency, and structure stress is more reasonable, and keeps away
Cracking in webs problem is exempted from.
Though the problem of such a design solves cracking in webs, in Wavelike steel webplate and box beam top plate and chassis connection sections
Position, but seems abnormal crucial.Because Wavelike steel webplate is directly connected to whole bridge structure with the joint portion of concrete roof and floor
Bearing capacity and stability, therefore shear connector be designed to restrict corrugated steel web plate composite box girder bridge bearing ability and durability
Key link, the problem of only solving connecting portion shear connector optimization design could effectively release Wavelike steel webplate and further send out
The contradiction of exhibition.
Utility model content
The purpose of this utility model is that the corrugated steel being directed in existing corrugated steel web box beam is connected by force with top plate bottom plate
The problem of degree is not high, a kind of simple in construction, high box girder with corrugated steel webs bridge plate of bonding strength of design.
The technical solution of the utility model is：
A kind of high-strength wave steel web box girder bridge plate, it includes top plate 1 and bottom plate 2, it is characterized in that the described He of top plate 1
Be connected between the both sides of bottom plate 2 by Wavelike steel webplate 3, the two ends of described Wavelike steel webplate 3 be embedded in top plate 1 and
The connector of bottom plate 2 is connected, described connector by flange plate 4, be vertically welded on flange plate 4 and be held into the weldering in concrete
Follow closely the 5, structural steel connecting member 6 between weldering nail and constitute structural steel connecting member through integral perforated rebar 7.
Described top plate 1, bottom plate 2 and the composition inverted trapezoidal structure of Wavelike steel webplate 3.
Described perforated rebar 7 is the deformed bar that screw-thread steel or surface carry annular rib.
The beneficial effects of the utility model：
The bonding strength of corrugated steel web and roof and floor of the present utility model is high, simple in construction, fundamentally improves ripple
The stressing conditions of shape steel web box girder bridge plate.
Brief description of the drawings
Fig. 1 is box girder with corrugated steel webs bridge plate section structure schematic diagram of the present utility model.
Fig. 2 is the structural representation of corrugated steel web connector of the present utility model.
Embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As shown in Figure 1-2.
A kind of high-strength wave steel web box girder bridge plate, it includes top plate 1 and bottom plate 2, described top plate 1 and bottom plate 2
It is connected between both sides by Wavelike steel webplate 3, and is in inverted trapezoidal structure, as shown in Figure 1.The two of described Wavelike steel webplate 3
End is connected with being embedded in the connector of top plate 1 and bottom plate 2, and described connector is as shown in Fig. 2 it is by flange plate 4, vertical welding
It is connected on flange plate 4 and is held into the weldering in concrete and follows closely the 5, structural steel connecting member 6 between weldering nail and pass through structural steel connecting member
Integral perforated rebar 7 is worn to constitute.In order to increase frictional force, perforated rebar 7 is with using screw-thread steel or surface during specific implementation
Deformed bar with annular rib is advisable.
Connector of the present utility model is strengthened from multiple directions so that web can overcome each to stress, and intensity is obtained
To thorough improvement.
The utility model is not directed to partly same as the prior art or can realized using prior art.
