Description
Technical field
The utility model relates to railway bridge noise barrier technical field of construction, particularly relates to a kind of bridge sound barrier basis cast-in-situ template braced structures.
Background technology
Sound barrier is mainly used in sound insulation and noise reducing in the traffic urban operating mechanisms such as speedway, overhead composite road, urban light rail subway, controls traffic noise to the impact in region, nearby urban, also can be used for the sound insulation and noise reducing of factory and other noise source.
Sound barrier is divided into the reflection-type sound barrier of pure sound insulation, and the compound sound barrier combined that absorbs sound and insulate against sound, and the latter is that more efficiently sound insulation is worked it out.Most sound barrier all selects the product of sound absorption and sound insulation mixed type, and the feature of this type product controls targetedly the generation of road noise and transfer characteristic.If automobile and road friction sound or locomotive and track friction sound are in road bottom, sound has the feature by screen body top diffraction, absorbs sound up and down so adopt in design, and the structure of middle sound insulation, can weaken the diffraction of noise so effectively; Use transparent reflection-type sound barrier in the middle of sound barrier, effectively can interrupt the route of transmission of sound wave; Simultaneously also for driver and resident provide an open visual field environment.
Sound barrier can be divided into railway sound barrier, road sound barrier, civic landscape sound barrier, residential block noise reduction barrier etc. according to purposes.
For road sound barrier, civic landscape sound barrier and its noise reduction barrier of resident can synchronously complete sound barrier foundation construction when main body construction, but, in current railway construction process, mostly adopt elevated structure, the case beam set up is typical construction, and, railway sound barrier is erection completely not, therefore, sound barrier basis needs carry out cast-in-place after box beam erection, the cast-in-place process in existing sound barrier basis, first need to wear steel pipe in advance in Bridge Pier Construction process, the parts such as bracket and support are fixed by the high-strength bolt be located in steel pipe during construction, last installing after template carries out precompressed at cradle top is poured into a mould, reach until concrete and relate to form removal after intensity, the associate member such as striking and bracket in the lump, this kind of method complex operation, and after completing cast, reserved steel pipe needs to use concrete shutoff, duty cycle is long.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of bridge sound barrier basis cast-in-situ template braced structures, hanging apparatus as horizontal shore is coordinated with fining twisted steel by adopting shoulder pole girder, horizontal shore directly withstands bridge pier side near the side of bridge pier, upper level support bar arranges Adjustable bracing bar by means of adjustment screw rod, for adjusting the levelness of bamboo slab rubber, Adjustable bracing bar sets up square steel, bamboo slab rubber is laid as bed die in square steel top, install template after precompressed completes and carry out pouring concrete, after completing cast, only the connection need unclamped between fining twisted steel and upper level support bar gets final product integral demounting, simplify the operation step, greatly shorten duty cycle, improve operating efficiency.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of bridge sound barrier basis cast-in-situ template braced structures, comprising at least two overlaps along the uniform horizontal shore of sound barrier basis bearing of trend, be arranged on the often adjustable supports two ends overlapped on horizontal shore by means of adjustment screw rod and set up at least two square steel in two cover adjustable supports, be laid on the bamboo slab rubber on square steel and the take-up device for fixed level bracing frame, described horizontal shore one end contacts with bridge pier lateral surface, described square steel length direction is identical with sound barrier basis bearing of trend, and evenly lay along the length direction of adjustable supports.
Preferably, described horizontal shore comprises lower horizontal support bar, upper level support bar and inclined support bar, described upper level support bar and lower horizontal support bar be arranged in parallel, and described inclined support bar two ends are fixed with upper level support bar and lower horizontal support bar and uniform along upper level support bar length direction respectively.
Preferably, described take-up device comprises shoulder pole girder and fining twisted steel, described fining twisted steel is vertically arranged, described shoulder pole girder bearing of trend is identical with sound barrier basis bearing of trend, shoulder pole girder is arranged on bridge upper surface, fining twisted steel upper end is fixedly connected with shoulder pole girder, and nut check is used through after upper level support bar in its lower end.
Preferably, adjustment screw rod arranges at least two, and with the nut screw connection being welded on upper level support bar soffit after upper level support bar is passed in adjustment screw rod lower end, adjustment screw rod upper end supports Adjustable bracing bar
The beneficial effect that produces of technique scheme is adopted to be: to coordinate hanging apparatus as horizontal shore with fining twisted steel by adopting shoulder pole girder, horizontal shore directly withstands bridge pier side near the side of bridge pier, upper level support bar arranges Adjustable bracing bar by means of adjustment screw rod, for adjusting the levelness of bamboo slab rubber, Adjustable bracing bar sets up square steel, bamboo slab rubber is laid as bed die in square steel top, install template after precompressed completes and carry out pouring concrete, after completing cast, only the connection need unclamped between fining twisted steel and upper level support bar gets final product integral demounting, simplify the operation step, greatly shorten duty cycle, improve operating efficiency.
