Description
Technical field
The present invention relates to a kind of railways and highway to have sound insulation and noise reduction or the bridge in demand location of keeping out the wind, specifically a kind of iron
Driving totally enclosed type box beam in the case of road.
Background technology
Totally enclosed type sound barrier is not yet had on conventional railway or high-speed railway both at home and abroad at present, it is only individual semiclosed
The input application of formula sound barrier.Such as Shanghai-Hangzhou visitor specially uses semi-enclosed sound barrier, the type noise barrier structure is by box beam, steel canopy
Frame, acoustic board and sound panel are composed, and are generally used for the more demanding environment sensitive spot of sound insulation, noise reduction, sound insulation and noise reduction sound-absorbing
Effect is opposite to get well；For urban road and urban track traffic sound barrier, mostly use semi-enclosed identical with aforementioned railway
Form, structure height is smaller than railway, and wind area is small, and without bullet train aerodynamic effect and vibration problem, conserves in addition
Repair is smaller than railway to traffic impact；For another example Sai Van Bridge in Macau case expert railway carriage beam, using the double girders of separate type, inside box beam
Flyunder is set, use can be just opened when only upper deck of bridge is closed during typhoon.Although semi-enclosed sound barrier and case
Put into application in expert's railway carriage Liang highways and railway, but its problem of it is also very prominent：
1. semi-enclosed sound barrier generally uses steel structure framework, cost is high, and late maintaining maintenance capacity is big, and sound insulation is imitated
Fruit is not good enough；
2. urban road and the semi-enclosed noise barrier structure height of urban track traffic are smaller than railway, no train general mood is dynamic
Power problem, and it is small to traffic impact compared to maintenance for railway, therefore be difficult to apply in railway；
3. although the case expert railway carriage beam scheme similar with Sai Van Bridge in Macau plays gear wind action well, its beam
Bottom is wider, therefore substructure quantities is also larger；
4. integrated box expert's railway carriage beam body amount is excessive, construction method can only select cast-in-place, and project cost is high and to environment
It influences big.
Invention content
Existing a series of problems is applied on elevated bridge for existing semi-enclosed sound barrier and case expert's railway carriage beam,
It can reach extraordinary soundproof effect the purpose of the present invention is to provide one kind and improve stock utilization reduction engineering and make
Driving totally enclosed type box beam in valence, construction railway box convenient, with wind resistance small to Coherent traffic noise.
In order to achieve the above objectives, driving totally enclosed type box beam in the railway box that the present invention designs, it is characterised in that：Including enclosing
At the top plate and bottom plate of rectangular cross-section and two side plates；The side plate includes the connected partition board in end and box web；The top
Plate and the partition board are structure as a whole, and the bottom plate and the box web are structure as a whole；The partition board is axially spaced to be set
There are multiple lightlng holes, a light transmission sound panel is equipped in each lightlng hole.In this way, using fully closed chamber structure,
Train is set to box house, under the premise of not drawing high railway absolute altitude, increases deck-molding significantly, to have bigger
Span ability can reduce bridge pier quantity about 60%.
Preferably, the junction of the top plate and the partition board is equipped with local thickened area；The top plate, partition board and part add
Stress rib is arranged in thick area, using cast-in-place integrated molding.In this way, when lower half portion that is to say that bottom plate and the construction of box web are completed
Afterwards, you can pour top half (that is to say top plate, partition board and local thickened area) directly over, so eliminate conventional cast-in-place
The holder of beam simultaneously avoids the interference to traffic under bridge, and construction is convenient；Meanwhile top half can play the role of sound barrier,
And be thick and solid concrete material, expensive metal or penetrating plate sound barrier expense are not only eliminated, but also than conventional sound-screen
The soundproof effect of barrier is more preferable, and durability is more preferable.
Preferably, at beam-ends the bottom plate thickness be more than span centre at the bottom plate thickness.
Preferably, the box web includes the first web and the second web；First web one end and institute
The connection of second web one end is stated, the first web other end is connect with bottom end, the other end of second web and institute
State plate top surface connection.
Preferably, angle at an acute angle between first web and the second web, first web and the bottom plate it
Between angle in obtuse angle.
It is further preferred that arrange stress rib in first web, the second web and bottom plate, using cast-in-place or prefabricated one
It is body formed.
It is further preferred that second web it is axially spaced be equipped with multiple ventilation holes, the ventilation hole by top plate, every
The space that plate, the second web and bottom plate surround is connected to the first web, the second web with the space that bottom plate surrounds.Ventilation hole increases
Air circulation in box beam body balances the draught head inside and outside box beam and plays and leads to wind action in case
It is further preferred that the top plate, partition board, the first web and bottom plate surround both ends be opening and rectangular cross-section
Enclosure space.Fully closed structure may make influence of the train from strong wind, withdrawal of train or limit when avoiding typhoon weather
Speed.
Preferably, the side wall of second web, which is equipped with, checks aisle.
It is further preferred that the top for checking aisle and being located at ventilation hole in the vertical direction.
The beneficial effects of the invention are as follows：One, using fully closed chamber structure, train is set to box house,
Under the premise of not drawing high railway absolute altitude, deck-molding is increased significantly, to have the span ability of bigger, can reduce bridge pier number
Amount about 60%；Two, babinet is divide into upper part and lower part, and prefabricated trough girder can be used in lower half portion, will again be existed after groove profile erection
It rides and pours top half, and two parts participate in whole Force Calculation together so that box beam overall stiffness and stability are significantly
Enhancing, and the holder of conventional cast-in-place beam is eliminated, the interference to traffic under bridge is also avoided, is constructed than convenient；Third, upper half
Part includes mainly top plate and partition board, is thick and solid concrete material, plays the role of sound barrier jointly, compared with prior art greatly
It is big to eliminate the expense of expensive metal or penetrating plate sound barrier, and better soundproof effect is achieved, it is both to also improve
Durability；4th, fully closed structure makes influence of the train from strong wind, withdrawal of train or limit when avoiding typhoon weather
Speed.
