Abstract
Bridge construction construction method based on cradle construction, bridge construction construction site is equipped with two Hanging Baskets, two Hanging Baskets are arranged back-to-back, the direction that two cradle constructions advance is to be away from each other, the Hanging Basket includes Rhombic Truss, include the following steps, the weight for the box beam for needing to lift by crane in this construction is first determined before selection Hanging Basket；Hanging Basket is selected according to the weight of box beam, when selecting Hanging Basket, the loading force of two Hanging Baskets is less than the weight of box beam, and the loading force of four Hanging Baskets is greater than the weight of box beam.
Description
Technical field
The present invention relates to the bridge construction construction methods based on cradle construction.
Background technique
The construction method that technology is new, speed is fast, easy for construction and economic is constantly searched in bridge construction.Box beam is in work
The construction method for arriving construction site assembly after factory is prefabricated again is widely adopted therewith, and this construction technology reduces bridge construction pair
The influence of urban transportation improves the technical level of overpass engineering.The bridge construction construction method is needed by erection crane,
It needs to build erection crane on construction ground, is removed again after the completion of lifting.
The prestressed concrete continuous beam of Long span is widely used Hanging Basket and carries out cantilever pouring construction.So-called cradle construction,
Refer to when pouring cantilever glider bridge, using basket method, is segmented cantilever operation on the spot.It does not need erect bracket and without using large size
Loop wheel machine.Cradle construction compared with other methods, have many advantages, such as structure is light, it is simple and convenient to spell system, without ballast.
When above-mentioned form of construction work occurs simultaneously, needs first to tear open Hanging Basket and need two sets of equipment in assembled erection crane, and come
It is relatively complicated to return dismounting.
Summary of the invention
It is an object of the invention to overcome the shortcomings of the prior art, Hanging Basket realization lifting can be efficiently used by providing one kind
The bridge construction construction method based on cradle construction.
Bridge construction construction method of the present invention based on cradle construction, bridge construction construction site are equipped with two Hanging Baskets,
Two Hanging Baskets are arranged back-to-back, and the direction that two cradle constructions advance is to be away from each other, and the Hanging Basket includes Rhombic Truss, including walks as follows
Suddenly, the weight for the box beam for needing to lift by crane in this construction is first determined before selection Hanging Basket；Hanging Basket, selection are selected according to the weight of box beam
When Hanging Basket, the loading force of two Hanging Baskets is less than the weight of box beam, and the loading force of four Hanging Baskets is greater than the weight of box beam.
Wherein, when needing to lift by crane box beam, wherein side Hanging Basket and other side Hanging Basket positioned at same construction area are combined, and two
The Rhombic Truss of Hanging Basket overlaps setting；The wherein side Hanging Basket of another construction area is combined with other side Hanging Basket, the water chestnut of two Hanging Baskets
The overlapping setting of shape truss；Hanging Basket after recombination lifts by crane the box beam between adjacent two construction area.
Wherein, Rhombic Truss side is equipped with a mounting disc, and mounting disc is equipped with open-work, when two Rhombic Truss combine, two water chestnuts
Mounting disc on shape truss overlaps and fastener is used to fix.
Solution in compared with the prior art, the invention has the advantages that: the present invention can remove erection crane from when implementing
Equipment can be used Hanging Basket equipment as erection crane equipment, to reduce construction equipment spending, can make full use of original extension
Basket improves construction efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of Hanging Basket normal service condition of the present invention.
Fig. 2 is structural schematic diagram when Hanging Basket of the present invention is used as erection crane.
Specific embodiment
With reference to the accompanying drawing and the invention is further illustrated by the examples.
Referring to Fig. 1 to Fig. 2, the bridge construction construction method based on cradle construction described in the present embodiment, bridge construction construction
Place is equipped with two Hanging Baskets 1, and two settings back-to-back of Hanging Basket 1, the direction that the construction of two Hanging Baskets 1 is advanced is to be away from each other, and the Hanging Basket 1 includes
Rhombic Truss further includes following steps, and the weight for the box beam 2 for needing to lift by crane in this construction, box beam are first determined before selection Hanging Basket 1
2 be the prefabricated component of bridge construction；Hanging Basket 1 is selected according to the weight of box beam 2, when selecting Hanging Basket 1, the loading force of two Hanging Baskets 1 is small
In the weight of box beam 2, the loading force of four Hanging Baskets 1 is greater than the weight of box beam 2.Although original Hanging Basket 1 can not be hung in the mechanism
Box beam 2 is played, but the Hanging Basket 1 ' after combination can be used as erection crane using capable of hoisting box beam 2, this method compares traditional construction mode
It is more convenient.
When needing to lift by crane box beam 2, wherein side Hanging Basket 1 and other side Hanging Basket 1 positioned at same construction area are combined, and two hang
The Rhombic Truss of basket 1 overlaps setting；Wherein side Hanging Basket 1 and the other side Hanging Basket 1 of another construction area are combined, two Hanging Baskets 1
Rhombic Truss overlapping setting；Hanging Basket 1 ' after combination lifts by crane the box beam 2 between adjacent two construction area.
In the specific implementation, the construction of Hanging Basket 1 is usually to extend to construct from bridge pier center to two sides to the present embodiment, Hanging Basket
After 1 cantilever casting construction certain distance, the side Hanging Basket 1 on same bridge pier is removed, by the Hanging Basket of Hanging Basket 1 component and the other side of dismounting
The loading force of 1 split, former Hanging Basket 1 enhances, and the Hanging Basket 1 on another bridge pier does same processing, and the Hanging Basket 1 after split is hung as bridge floor
Machine it is practical by prefabricated box beam 2 sling complete bridge floor close up.
Rhombic Truss side is equipped with a mounting disc, and mounting disc is equipped with open-work, when two Rhombic Truss combine, two Rhombic Truss
On mounting disc overlap and fastener used to fix.Bolt tightens through hole using nut.
The above is only a preferred embodiment of the present invention, it should be understood that for the ordinary skill people of the art
For member, under the premise of not departing from the principle of the present invention, other improvements and modification can also be made, it all should be by claims
In identified protection scope.
