Description
Technical field
The present invention relates to railway steel reinforced concrete bondbeam technical field, more particularly to a kind of contact net of railway steel reinforced concrete bondbeam is stood
Column foundation and steel reinforced concrete combination bridge.
Background technology
Steel reinforced concrete bondbeam is by steel and a kind of combined new structure formed of two kinds of materials of different nature of concrete.
It is the reasonable combination of two kinds of materials of steel and concrete, has given full play to that steel tensile strength is high, plasticity is good and concrete anti-compression
Can be good the advantages of, and the shortcomings that can overcome the disadvantages that each other, therefore in modern bridge structure, steel reinforced concrete bondbeam increasingly becomes bridge hair
One of Main way of exhibition.Electric railway in recent years has become the mainstream type of modernized railway, is widely used in high fast
In the construction of fast railway and urban track traffic, many non-electrified railways also realize electrified upgrading in succession, wherein connecing
Net-fault is one of common two kinds of supply network modes of electric railway, is supplied as what downline overhead was set up to electric locomotive
The transmission line of electricity of the special shape of electricity, mainly by contact suspension, support device, positioning device, pillar and a few part groups in basis
Into.
Existing mainly to have following two modes when setting contact net basic on steel reinforced concrete combination bridge, one kind is that design exists
On bridge pier, another is designed on the bridge floor flange plate of steel reinforced concrete bondbeam.Contact net basic is set on bridge pier, although base
The simple structure of plinth, but position must be not easy to rationally dividing for column near bridge pier, since bridge structure stress is complicated and changeable
Cloth；Contact net basic is set on the floorings flange plate of steel reinforced concrete bondbeam, although there is no restriction to installation position, due to vertical
The weight of column is very heavy, it is necessary to reinforcing bar on floorings be strengthened, floorings are relatively thin to cause reinforcing bar overstocked, and difficulty of construction is big, right
Construction requirement is higher, and cost is higher, and construction efficiency is relatively low.
Invention content
It is an object of the invention to overcome in the prior art when setting contact net basic on steel reinforced concrete combination bridge, item is limited
