Abstract
The utility model discloses a construction structure for carrying out prefabricated erection of box beams on a bridge, which comprises a side span bridge abutment of a first span and two side bridge piers of a second span, wherein the side span bridge abutment and the side bridge piers are sequentially arranged; a bridge abutment capping is erected on the side span bridge abutment; a first bridge pier bent cap and a second bridge pier bent cap are respectively erected on the two side bridge piers; at least two support cushions are respectively arranged on the bridge abutment capping and the first and second bridge pier bent caps at intervals; and the box beams are longitudinally erected on the support cushions correspondingly arranged on the side span bridge abutment and the first bridge pier bent cap and on the support cushions correspondingly arranged on the first bridge pier bent cap and the second bridge pier bent cap. The structure is not influenced by the geographical environment, so that the construction structure is suitable for areas with large fluctuation of the geographical altitude difference; and in the process of moving the beams, the installation of large-scale equipment such as a gantry crane and a bridge girder erection machine is omitted, and thus, the labor production efficiency is improved, the cost is saved and the construction period is saved.
Description
Technical field
The utility model relates to the constructing structure of bridge, relates in particular on bridge, to carry out the beam prefabricated constructing structure that sets up of case.
Background technology
In bridge construction, prefabricated case beam is to build a kind of bridge superstructure form that bridge construction the most generally adopts.At present for the prestressed concrete continuous rigid-framed bridge of crossing over deep valley, great river, torrent.Substructure master's bridge bridge pier adopts the hollow thin-wall pier, pile foundation, and superstructure master bridge adopts the job practices of cantilever pouring to construct, and adopts post-tensioned prestressed box beam for the access bridge superstructure more.Case beam for the sheet number is many is prefabricated at precasting yard; Erection construction is more common method by setting a roof beam in place in proper order successively, and few for case beam sheet number, the physical features at the access bridge place discrepancy in elevation again rises and falls big; When physical features is complicated; By routine at precasting yard prefabricated case beam, erection method, the construction relatively the difficulty, also unreasonable economically.
Learn the patent of having authorized through retrieval:
1 application number is that the Chinese patent of CN201010232662.3 discloses " mounting method of post tensioned prestressed concrete box girders ", the present invention relates to a kind of mounting method of post tensioned prestressed concrete box girders.The mounting method of post tensioned prestressed concrete box girders; It is characterized in that it comprises the steps: 1) installation of bracing or strutting arrangement: in a tension of prestressed tendon section; Direction along post tensioned prestressed concrete box girders is installed is laid first bracing frame and second bracing frame; On first bracing frame, lay first slideway, on second bracing frame, lay second slideway; 2) installation of post tensioned prestressed concrete box girders: 1. adopting hoisting weight is that the 100t straddle truck is placed on the handling of 5-12 piece post tensioned prestressed concrete box girders on first slideway and second slideway of bracing or strutting arrangement; 2. through bottle gouard moved by hands post tensioned prestressed concrete box girders is walked on first slideway and second slideway two adjacent post tensioned prestressed concrete boxes are carried out assembly unit.
2 application numbers are: the Chinese patent of CN201010285591.3 discloses " the empty prefabricate of a kind of large concrete boxes deck-molding, move beam, deposit beam, the job practices of assembly unit "; The invention discloses the empty prefabricate of a kind of large concrete boxes deck-molding, move beam, deposit beam, the job practices of assembly unit, it is characterized in that may further comprise the steps: 1) set up high stake prefabricated platform; 2) between high stake prefabricated platform and bridge pier, set up and move joist steel pipe holder and steel slide rail; 3) on high stake prefabricated platform, build the matching beam section; 4) the matching beam section that will build is built new beam section as the end mould of the next one new beam Duan Yiduan to be poured; 5) after new beam section is built, the matching beam section is transported to design attitude as beam section to be assembled, simultaneously new beam section is moved forward as next matching beam section; 6) the coupling face that beam section to be assembled is vertically moved on to the assembled beam section end is as the spliced girder section, the position of adjustment spliced girder section make its meet with bridge pier on the assembled beam section requirement of splicing; 7) spliced girder section and assembled beam section are spliced.Job practices of the present invention through the beam section prefabricate and deposit beam for a long time, effectively make the precast beam section under free state, accomplish most of shrinkage strain of beam body, it is poor because of the different contractions that produce in the length of time to eliminate the adjacent beams section, thereby the elimination crack.
The 1st the disclosed patent of patent " mounting method of post tensioned prestressed concrete box girders " rises and falls big at topographical elevation difference, inapplicable in the bridge in the river, mountain valley that physical features is complicated.
The empty prefabricate of the disclosed case deck-molding of the 2nd patent, move beam, deposit beam, the goal of the invention of the job practices of assembly unit is to eliminate the crack.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art; Provide a kind of and rise and fall greatly at topographical elevation difference, a kind of beam prefabricated constructing structure that sets up of case that on bridge, carries out when physical features is complicated adopts this structure to improve labor productivity; Practice thrift cost, saved the duration.
A kind of beam prefabricated constructing structure that sets up of case that on bridge, carries out of the utility model; It comprises the both sides bridge pier that the first end bay abutment and second of striding that sets gradually; Put on the shelf at described end bay abutment and to be provided with abutment platform cap; The first bridge pier bent cap and the second bridge pier bent cap on the bridge pier of described both sides, have been set up respectively; On described abutment platform cap, the first and second bridge pier bent caps, be arranged at intervals with at least two bearing pad stones respectively, all longitudinally setting up the case beam on the bearing pad stone of end bay abutment and the corresponding setting of the first bridge pier bent cap and on the bearing pad stone of the first bridge pier bent cap and the corresponding setting of the second bridge pier bent cap.
The advantage of the utility model: prefabricated the setting up of this structure case beam can utilize Bei Leiliang to construct on spanning, and Bei Leiliang can set up and remove at any time, and is very convenient, not influenced by geographical environment, thereby it is big to be applicable to that topographical elevation difference rises and falls, the physical features areas with complicated; Again owing to saved the installation of main equipments such as straddle truck, bridge formation machine when moving beam, thereby improve labor productivity, practiced thrift cost, saved the duration, and economical rationality.
