Description
Technical field
This utility model relates to science of bridge building field, specifically a kind of railway bridge contact net basic off normal device.
Background technology
Railway bridge contact net basic off normal device is used in redrilling on bridge at present, widens bridge deck width, sets up contact
Net foundation built-in bolt form.Owing to the distance between contact net and railway has minimum restriction, therefore when the short of width of beam body
With meet minimum allowable distance limit time, need casting concrete outside beam body to be used for widening beam body, then install in concrete and connect
The built-in fitting touched net.
There is following problem in the contact net basic processing mode of this type:
1, redrilling is needed in beam body；
2, the construction of rear pouring concrete is loaded down with trivial details；
3, the accessory structure such as railing needs drop-over to process.
Utility model content
The purpose of this utility model is to solve the deficiency that above-mentioned background technology exists, and proposes a kind of without in beam body
Need redrilling can meet the railway bridge contact net basic off normal device that contact net mounting distance limits.
In order to realize object above, a kind of railway bridge contact net basic off normal device that this utility model provides, including partially
Position pedestal and contact net basic, it is characterised in that: described off normal pedestal includes upper base plate, lower seat board and off normal connector, described
It is arranged in parallel between upper base plate and lower seat board, connects by off normal connector is fixing between them, the center of described upper and lower seat board
Horizontal off normal；The end face of described upper base plate is connected by fixing bolt with contact net column, and the underrun of described lower seat board is many
The individual pre-embedded bolt being embedded in contact net basic is connected with contact net basic, and the center of described upper base plate is at contact net column
On axis, the center of described lower seat board is on the axis of contact net basic, and the lower end of described pre-embedded bolt passes contact net basic
It is located in the beam body of railway bridge.
As preferred version of the present utility model, in described beam body, it is provided with lower pre-embedded steel slab, the lower end of described pre-embedded bolt
Through the hole, location in lower pre-embedded steel slab and be secured to connect.
Further, described contact net basic upper surface is provided with pre-embedded steel slab, and pre-embedded bolt upper end passes upper pre-buried steel
Under location Kong Bingyu in plate, seat board is fixing connects.
Further, described off normal connector is I-steel.
Yet further, the off normal connector side between described upper base plate and lower seat board is provided with stiffener.
The most further, the horizontal off normal of described pre-embedded bolt that described fixing bolt is corresponding.
Upper base plate that this utility model is arranged by off normal and lower seat board, it is achieved that the covert outer of contact net column moves, and makes
The installation site of contact net meets the distance limit with railway.This device directly can be preset, therefore without rear when beam body is constructed
The accessory structures such as the phase is redrilling in beam body, railing process without drop-over.
Accompanying drawing explanation
Fig. 1 is contact net scheme of installation in prior art.
Fig. 2 is structural representation of the present utility model；
In figure: off normal connector 1, upper base plate 2, lower seat board 3, contact net column 4, contact net basic 5, pre-embedded bolt 6, under
Pre-embedded steel slab 7, beam body 8, fixing bolt 9, upper pre-embedded steel slab 10.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment the utility model is described in further detail.
Embodiment: a kind of railway bridge contact net basic off normal device as shown in Figure 1 and Figure 2, including off normal pedestal with contact
Net basis 5, described off normal pedestal includes upper base plate 2, lower seat board 3 and off normal connector 1, between described upper base plate 2 and lower seat board 3
Being arranged in parallel, connect by off normal connector 1 is fixing between them, described off normal connector 1 is I-steel, off normal connector 1
Side is provided with stiffener, the central horizontal off normal of described upper and lower seat board.
The end face of described upper base plate 2 is connected by fixing bolt 9 with contact net column 4, the underrun of described lower seat board 3
Multiple pre-embedded bolts 6 being embedded in contact net basic 5 are connected with contact net basic 5, and the center of described upper base plate 2 is at contact net
On the axis of column 4, the horizontal off normal of described pre-embedded bolt 6 that described fixing bolt 9 is corresponding.The center of described lower seat board 3
On the axis of contact net basic 5, the lower end of described pre-embedded bolt 6 is located in the beam body 8 of railway bridge through contact net basic 5.
Be provided with lower pre-embedded steel slab 7 in described beam body 8, the lower end of described pre-embedded bolt 6 through the location Kong Bingyu in lower pre-embedded steel slab 7 its
Fixing connection.Described contact net basic 5 upper surface is provided with pre-embedded steel slab 10, and pre-embedded bolt 6 upper end passes upper pre-embedded steel slab 10
In location Kong Bingyu under seat board 3 is fixing connects.
Upper base plate 2 that this device is arranged by off normal and lower seat board 3, it is achieved that the covert outer of contact net column 4 moves, and makes to connect
