Description
Technical field
The present invention relates to field of bridge construction, relate in particular to a kind of bridge Y types pier construction combinative structure platform and
Its installation method.
Background technology
At present, known Y types bridge construction platform has various ways, but there is a problem that certain.For universal not
And geological conditions compared with hard formation blocked up suitable for Muddy Bottoms coating, it is impossible to which the intensity of effectively utilizes pier shaft is transmitting vertical lotus
Carry, supporting removal is difficult after the completion of construction, typically can only be cut off using the bottom, produce larger waste to material, and in navigation
Under conditions of having high demands cannot the bottom cut off, universality is poor, it is impossible to greatest extent play steel platform load-carrying properties.
The construction method of the great-angle Y type pier stud announced by publication No. CN104746435A employs substantial amounts of steel-pipe pile knot
Structure and slant-pull structure system, need to carry out substantial amounts of piling construction, and steel using amount are big.Y types pier construction terminate after steel-pipe pile not
Easily pull out, waste of material can only be caused by the way of excision.
The concrete structure formwork bracing frame of the bridge V-type bridge pier announced by publication No. CN202390763U, its V for adopting
Type bracing frame is the method for carrying out bent cap concrete structure construction after the construction of V limbs, it is impossible to which effectively application is constructed with V limbs.
A kind of wide-angle V-shaped pier that publication No. C102888815A and CN202954299U are announced and 0# block box beams are poured
Building construction method needs to lay a large amount of supports, and material consumption is big, also needs to process ground.
A kind of Y types pier template and support system and publication No. CN101481902A that publication No. CN203007846U is announced
The V type pier inclined leg combined type support for continuous rigid frame bridge announced and layered cast-in-situ construction method, its erection depend on enclosing for pontic
Fender pile and the drilled pile for separately setting, and multiple tracks is laid to lacing wire, support connection complicated so that the program is fitted in implementation process
Answering property is poor, and enforcement difficulty is big, does not apply to and is not provided with fender post and does not set the suspended deck structure of drilled pile.
The content of the invention

It is located on the inside of described many root type girder steels in the column of Y type piers to be poured, then by the column of Y type piers to be poured
Reinforcing bar makes the column of section steel beam and Y type piers through default reinforced hole on the inner side edge of a wing of the section steel beam being correspondingly arranged and web
Reinforcing bar be connected；
(4) pour the column of Y type piers；
(5) when the concrete strength of the column of Y type piers reaches requirement, many concrete filled steel tube diagonal brace bottoms are welded respectively
It is connected on vertical pre-embedded steel slab and horizontal pre-embedded steel slab in succession and the other end is respectively welded on the section steel beam being correspondingly arranged；
(6) Bailey beam is laid on many root type girder steels of the homonymy for having supported, and described Bailey beam is adopted with section steel beam
Take spot welding and securing member is fixed；
(7) distribution beam is laid respectively in Bailey beam described in the left and right sides, described distribution beam and Bailey beam are using fastening
Part and spot welding connection；
(8) the outer wall shape respectively according to Y type socle V-arrangements to be poured in the distribution beam of the left and right sides lays Y type piers
Formwork-support.
Using the invention has the beneficial effects as follows：
(1) platform is supported on cushion cap eventually through concrete filled steel tube diagonal brace and is connected with pier stud by pre-buried mode, right
Underlying geological condition does not require that assembling and disassembling is convenient, and steel using amount is few, easy construction；
(2) concrete filled steel tube has good mechanical property, has compared to traditional steel pipe support structure preferably anti-
Pressure performance.
(3) the original reinforcing bar of pillarwork can be passed through from the reinforced hole of section steel beam, will not be because of the pre-buried connection of section steel beam
Laying to the intrinsic reinforcing bar of structure is impacted；
(4) reinforcing bar penetrated in opening up the shaped steel flange of beam of reinforced hole, web improves the ductility of anchor structure, it is to avoid
The brittle break of anchor system；
(5), in casting process, the concrete performance of tapping can be improved, and the shearing resistance for substantially increasing concrete is strong
Degree；
(6) combined system is applicable to current known any pier shaft height, the battered leg of the Y type piers of battered leg angle and pours and apply
Work platform, intensity are high, flexible arrangement.
