The method comprises the following steps: dividing a trough girder body into three members, which are an integral member of a left longitudinal girder and a left web plate, a bottom plate member and an integral member of a right longitudinal girder and a right web plate respectively, along a longitudinal vertical slit; casting in place on a substructure of the bridge and simultaneously prefabricating the three members on a prefabrication site; reserving a transverse reinforcement joint at the bottom of the prefabricated member and reserving transverse reinforcement joints on the left and right sides of the bottom plate; conveying the prefabricated members to the construction site after the construction and maintaining of the substructure are finished, lifting to a specific location by lifting equipment, arranging longitudinal reinforcements on site, binding, lapping or welding with the reserved transverse reinforcement joints, then pouring concrete at a joint section and performing construction and maintaining of the concrete at the joint section to form a body structure of the trough girder bridge. According to the construction method, the defects existing in the prior art are overcome, the construction processes can be simplified by prefabricating the members on the prefabrication site, the construction progress is quickened, the construction efficiency is improved, and the construction cost is reduced.
Description
Technical field
The invention belongs to technical field of civil engineering, relate to a kind of method for bridge construction, more particularly relate to the job practices of a kind of Middle Or Small Span footpath flute profile beam bridge.
Background technology
The job practices of on the spot placing (or abbreviation " cast-in-place ") is mainly adopted in the construction of existing flute profile beam bridge, this job practices is built after maintenance finishes at bridge substructure, carry out again building of superstructure, master operation comprises: set up at the construction field (site) support and template, reinforcing bar bend the welding of moulding and joint, the welding of cage of reinforcement, install and fix, the concrete system of mixing, transport, build, vibrate, maintenance and form removal, support dismounting work etc.Existing job practices working procedure is many, construction period is long, the setting up error and can exert an influence to construction quality of support and template, construction quality is subjected to the such environmental effects such as temperature humidity of job site large, the concrete shrinkage and creep effect of cast in situs is obvious, construction quality is wayward, and efficiency of construction is not high.Patent of invention ZL02137151.2 discloses a kind of job practices of longitudinally assembling prefabricated subsection of channel beam, this job practices be with channel beam along bridge to the channel beam that is divided into a section with horizontal perps, carry out prefabricate, again a section prefabricated channel beam is carried out assembly unit, then stretch-draw longitudinal prestressing muscle, form the channel beam agent structure, the advantage of this patent of invention is to have adopted the prefabricated subsection channel beam, avoided the on the spot defective of cast-in-place method, but, this patent of invention is only applicable to adopt the flute profile beam bridge of longitudinal prestressing muscle, to Middle Or Small Span footpath flute profile beam bridge, adopt plain bars just can satisfy the requirement of force and deformation, need not to adopt the longitudinal prestressing reinforcing bar, so can't adopt the job practices of this patent of invention to construct to Middle Or Small Span footpath channel change bridge.
Summary of the invention
The object of the invention is to overcome the defective of prior art, the job practices of a kind of Middle Or Small Span footpath flute profile beam bridge is provided.
In order to achieve the above object, technical scheme of the present invention is:
The job practices of a kind of Middle Or Small Span footpath flute profile beam bridge, the step that comprises is: one, longitudinally perps is divided into three kinds of members with the flute profile beam bridge, i.e. the integrated member of left longeron and left web, the integrated member of base plate member and right vertical beam and right web; Two, cast in situs channel beam bridge substructure is simultaneously at the described three kinds of members of the prefabricated step 1 in prefabricated place; And in the bottom of the integrated member of prefabricated left longeron and left web and the bottom of the integrated member of right vertical beam and right web be reserved with the transverse reinforcement joint by design specifications respectively, be reserved with the transverse reinforcement joint on the limit, the left and right sides of base plate by design specifications; Three, three kinds of prefabricated members are transported to the job site, utilize lifting appliance to be lifted into assigned address, some longitudinal reinforcements that are connected with reservation transverse reinforcement joint of site layout project carry out colligation overlap joint or welding with reservation transverse reinforcement joint; Four, build the junction concrete, the butt joint section concrete carries out construction and maintenance, forms the agent structure of flute profile beam bridge.
Wherein said transverse reinforcement joint is divided into two-layer up and down; The end shape of described transverse reinforcement joint is hook solid.
The transverse reinforcement joint that described base plate member is reserved with equates with the height of the transverse reinforcement joint that the bottom of the integrated member of the bottom of the integrated member of described longeron and left web and right vertical beam and right web is reserved with, horizontal level stagger in order and near.
The present invention compared with prior art has following advantage and beneficial effect:
(1) but the top and the bottom structure parallel construction of bridge shortens the construction period;
(2) channel beam is broken down into three kinds of members and carries out prefabricatedly, simplifies job site action, accelerating construction progress;
(3) prefabricated units are conducive to the heavy industrialization manufacturing, and the construction quality of member is not subjected to the impact of job site conditions environmental, have higher making quality in prefabricated place;
(4) the concrete support of junction and template only need be set up in the job site, have simplified working procedure, have saved construction cost;
(5) be conducive to organize mechanized construction, fully guarantee construction safety.
Description of drawings
Fig. 1 is three kinds of prefabricated units schematic perspective views of the present invention.
Fig. 2 is component connector reinforcement placement schematic diagram of the present invention.
Fig. 3 is the A-A cross section view of Fig. 2.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, the job practices of a kind of Middle Or Small Span footpath flute profile beam bridge, at first longitudinally perps is divided into three kinds of members with the flute profile beam bridge, the integrated member 1 that these three kinds of members are respectively left longeron and left web, base plate member 2, the integrated member 3 of right vertical beam and right web.In bridge substructure cast in situs, prefabricated described three kinds of members in prefabricated place.
The work of prefabricated units comprises that support and template construct are in place, and lifting clasp and transverse reinforcement joint are reserved in the fabrication and installation of cage of reinforcement, and concreting also carries out maintenance.
The transverse reinforcement joint is reserved by design specifications in bottom at prefabricated units 1 and member 3, as shown in Figures 2 and 3, transverse reinforcement is divided into two-layer up and down, the transverse reinforcement joint is also reserved by design specifications in limit, the left and right sides at base plate 2, transverse reinforcement is divided into two-layer up and down, identical with the transverse reinforcement height of member 1 and member 3, horizontal level staggers in order and makes hook solid near, the end of transverse reinforcement by " highway reinforced concrete and prestressed reinforced concrete bridge are contained design specifications " (JTG D62-2004) requirement.
