Description
Technical field
The present invention relates to railway steel reinforced concrete bondbeam technical field, more particularly to contact net is vertical on a kind of railway steel reinforced concrete bondbeam
The installation method of column foundation.
Background technology
Steel reinforced concrete bondbeam be by steel and two kinds of materials of different nature of concrete it is combined made of a kind of new structure.
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 good advantage, 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 to electric locomotive as what downline overhead was set up
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
At.
Existing mainly to have following two modes when contact net basic is arranged on steel reinforced concrete combination bridge, one is designs to exist
On bridge pier, construction method is that the embedded bar of bridge pier top cap reinforcing bar and contact net basic has been bound on the cantilever slab of bridge pier,
Contact net basic cantilever slab is poured together with bridge pier top cap, while reserving good column built-in bolt sleeve, pre-embedded bolt is installed
With sleeve connection, contact net column is made to be connected firmly with basis, the base configuration is simple, but position must be near bridge pier, position
It is equipped with limit, since bridge structure stress is complicated and changeable, is not easy to the reasonable layout of column；Another is that design is combined in steel reinforced concrete
On the bridge floor flange plate of beam, construction method is the embedded bar of the encryption setting contact net basic on flange plate, by itself and master
Beam steel is connected, and then pours the concrete on contact net basic bridge floor flange plate together with concrete on girder, while pre-
Column built-in bolt sleeve has been stayed, pre-embedded bolt and sleeve connection are installed, so that contact net column is connected firmly with basis, the basis
Although to installation position, there is no restriction, since the weight of column is very heavy, it is necessary to reinforce reinforcing bar on floorings, floorings
Relatively thin to cause reinforcing bar overstocked, difficulty of construction is big, higher to construction requirement, 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 at installing contact net basis on steel reinforced concrete combination bridge, item is limited
Part is more, and difficulty of construction is big, and cost is higher, and construction efficiency is relatively low, and the above-mentioned deficiency such as of poor quality provides a kind of railway steel reinforced concrete bondbeam
The installation method of upper contact net upright post basic.
To achieve the goals above, the present invention provides following technical schemes：
The installation method of contact net upright post basic, comprises the following steps on a kind of railway steel reinforced concrete bondbeam：

Phase facilitates the lifting and installation of follow-up column, advantageously ensures that the verticality and stability of column, avoids down bar and sedimentation, nothing
Reinforcing bar on the bridge floor edge of a wing need to be encrypted, effectively reduce design strength and difficulty of construction, be conducive to save material, keep away
Exempt from the construction cost that science of bridge building is significantly increased, convenient for the installation site of planning arrangement column, improve the running quality of contact net,
Economy is promoted, the safety of railway transmission line of electricity is increased.
Preferably, also include to assemble the support member, the support member includes top plate, web and bottom in step a
Plate, each column lower section are connected at least provided with two webs, the bottom of each web there are one the bottom plate,
Top plate described in all web vertical connections, each bottom plate is perpendicular to the corresponding web.
It is further preferred that all top plates, web and bottom plate are steel construction piece, all top plates are welded to connect
Girder, all webs and bottom plate are spliced by high-strength bolt and the girder.
It is further preferred that in the step a, several ribbed stiffeners are transversely connected in the top plate bottom.
Using above-mentioned set-up mode, the intensity of upright post basic can be reinforced, effectively stablize support post, further avoid standing
Column is crooked or sinks, while ensureing to be stably connected with girder, effectively the stress of contact net is transferred to girder and bridge pier, guarantee
Load rationally, uniformly transmits.
Preferably, in the step a, all sleeves and WELDING STUDS are welded to connect the top plate.
It is further preferred that the step a is completed in factory.
Using aforesaid way, be conducive to the molding matter for effectively improving the sleeve and WELDING STUDS welding quality and support member
Amount improves construction quality and the safety of upright post basic, reduces pollution, improves efficiency.
Preferably, before the step b, the corresponding position connection of each support member is connected on the girder
Stiffener.
Preferably, in the step c, the concrete one at the top of concrete and the girder at the top of the support member
Body pours.
Using above-mentioned set-up mode, be conducive to rationally transmit stress, improve underlying strength and stability.
Preferably, the girder is plate girder or steel box-girder or Steel Truss Beam.
In conclusion compared with prior art, the beneficial effects of the invention are as follows：
