Description
Technical field
The utility model is related to combined type cast-in-place box beam bracket, naked rock geology combined type cast-in-situ box girder in particularly a kind of water
Mounting system.
Background technology
It is most of to use prefabricated, cantilever or incremental launching construction technique across river, the cross a river water stage casing access bridge concrete box girder more, still
It is connected more with ramp bridge as municipal bridge feature constantly strengthens, bridge deck width constantly increases, and behind approach span river.Without logical
Section in the water that boat is required, cast-in-situ box girder is compared with other forms（Especially cantilever and incremental launching construction technique）It is more economical practical.For
Above-mentioned needs are met, access bridge section box beam is designed frequently with variable cross-section cast-in-situ box girder.
Construction of cast-in-situ box-beam technique is very ripe, and box beam bracket typically uses steel-pipe pile support or continuous brackets.
But in the naked rock geology construction in water stage casing, basis of the conventional full framing without stabilization, and it is larger by water currents, easily occur
Entirety is toppled or damaged or destroyed by flood.Though conventional steel pipe support is avoided that the deficiency of full framing, waterborne to set up that support is long in time limit, high-altitude
Operating risk is high, steel pipe support is set up quality and is difficult to control to.When being constructed on ephemeral stream, support is set up, in demolishing process
Marine equipment is influenceed the cycle long by flood season, it is difficult to continuous construction.
Utility model content
The purpose of this utility model is to provide naked rock geology combined type cast-in-place box beam bracket system in a kind of water, main solution
Steel-pipe pile support and continuous brackets are applied in combination technical problem present in certainly above-mentioned prior art, the utility model, lead to
Cross Bailey bracket combination beam and the box beam load that continuous brackets are carried is transferred to infrastructure steel-pipe pile.
To achieve the above object, the technical solution of the utility model is：
Naked rock geology combined type cast-in-place box beam bracket system in a kind of water, it is characterised in that：It includes being sequentially connected down
Portion's stress steel-pipe pile, middle Bailey bracket combination beam, the part of top continuous brackets three.
Naked rock geology combined type cast-in-place box beam bracket system in described water, it is characterised in that：The Bailey bracket combination beam bag
Include stake top bracket, spandrel girder, Bailey bracket, shellfish thunder flower stand, distribution beam；Wherein：The Bailey bracket, shellfish thunder flower stand be connected to spandrel girder with
Between distribution beam, the spandrel girder is connected by bracket with stress steel-pipe pile, connection continuous brackets above the distribution beam.
Naked rock geology combined type cast-in-place box beam bracket system in described water, it is characterised in that：The spandrel girder uses H types
Steel, the distribution beam uses I-steel.
By above-mentioned technical proposal, the utility model has the following advantages that：
1. Integral Steel pile tube support is compared, modular support top uses continuous brackets form, substantially reduced existing
Pour box beam bracket and set up the time, reduce high-altitude working safety risk waterborne, reduce support quality control difficulty.
2. infrastructure uses naked rock geology pile method construction technology, and the basic stress for efficiently solving continuous brackets is steady
Qualitative question, by means of planting pile driving construction platform, after the completion of bracket basis construction, is converted to land construction by over-water construction, subtracts
Small construction of cast-in-situ box-beam risk and difficulty of construction.
When 3. being constructed on ephemeral stream, steel-pipe pile bracket basis can be with degree of safety flood, it is ensured that superstructure box beam connects
Continuous construction.And superstructure full framing is installed and Demolition Construction is not influenceed by flood season, is conducive to box beam to work continuously.
4. as municipal administration is constantly built across river, river bridge, wide cut variable cross-section cast-in-situ box girder gradually increases, the full hall of superstructure
Formula rack form is more flexible and convenient in box girder with variable cross section model sheetinstallat, it is easier to meet bridge appearance quality requirement.
Brief description of the drawings
Fig. 1 is positive structure schematic of the present utility model.
Fig. 2 is side structure schematic diagram of the present utility model.
Fig. 3 is spandrel girder supporting construction schematic diagram in the utility model.
Embodiment
Fig. 1-3 are referred to, the utility model discloses naked rock geology combined type cast-in-place box beam bracket system in a kind of water.Such as
Shown in figure：It includes the bottom stress steel-pipe pile 1, middle Bailey bracket combination beam 2, top continuous brackets 3 three being sequentially connected
Point.The mounting system both sides have cushion cap 9, the cushion cap 9 respectively with middle Bailey bracket combination beam 2, top continuous brackets 3 it is outer
Side is connected.
The Bailey bracket combination beam 2 includes stake top bracket 4, spandrel girder 8, Bailey bracket 5, shellfish thunder flower stand 6, distribution beam 7；Wherein：
The Bailey bracket 5, shellfish thunder flower stand 6 are connected between spandrel girder 8 and distribution beam 7, and the spandrel girder 8 passes through bracket 4 and stress steel-pipe pile 1
Connection, the top of the distribution beam 7 connection continuous brackets 3.
The spandrel girder 8 uses H profile steel, and the distribution beam 7 uses I-steel.
Specifically used method of the present utility model is as follows：
1. processing and fabricating bottom stress steel-pipe pile 1, stake top bracket 4, spandrel girder 8, distribution beam 7.
