2), during produce in factory, first make initial beam body section, be labeled as n piece;
3), using the initial beam body section made as matching segment, build next beam body section, and next beam body section be labeled as to n+1 piece;
4), repeat previous step, make all beam body section of residue such as n+2, n+3 piece, the beam the body section subsequently ownership being performed is transported to bridge construction scene;
5), start beam body section installation procedure: first n piece beam body section is installed, complete after the CONSTRUCTION OF CABLE-STAYED BRIDGE concerned process steps of n piece beam body section, lift subsequently n+1 piece beam body section, after n+1 piece beam body section is debugged, the steel work of n+1 piece beam body section and n piece beam body section is partly welded to connect, and the coupling face of n+1 piece beam body section and the concrete slab of n piece beam body section stitches by splicing and is connected;
6), lifting residue beam body section successively, repeating step 5) shown in beam body section installation procedure, until all bridge subsection installations.
Further, step 3) in, n piece beam body section is docked fixing temporarily with the steel work part of n+1 piece beam body section, and using the end face of concrete slab of n piece beam body section as the Side Template of building n+1 piece beam body section concrete slab, be equipped with the template of n+1 piece beam body section concrete slab bottom surface and other sides, concreting, forms n+1 piece beam body section.
A kind of steel reinforced concrete compound beam cable stayed bridge of the present invention glueds joint seam method of attachment, by each beam body section that is prefabricated in the factory and forms beam body and mutually mate, during construction, the bottom steel work of adjacent beams body section partly adopts and is welded and fixed, the top concrete slab of adjacent beams body section is stitched and is connected by splicing, can at utmost reduce site operation task, guarantee construction quality; Each component standardization, batch production degree are high, can reduce artificial demand, and in execution conditions severe (cold, many typhoons, be dried etc.) environment, have very big competitiveness at the scene.
Accompanying drawing explanation
Fig. 1 is combined beam structure schematic diagram in background technology;
Fig. 2 adopts cast-in-place wet seam by adjacent concrete plate 2 connection diagrams when compound beam is constructed in background technology;
Fig. 3 is that in the present invention, to take n beam body section be matching segment, builds n+1 piece beam body section schematic diagram.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
With reference to figure 3, a kind of steel reinforced concrete compound beam cable stayed bridge that the present embodiment is shown glueds joint seam method of attachment, and it comprises the following steps:
1), whole bridge partition is made into a plurality of beam body section in Xian factory, beam body section is that the integrally-built top of one-tenth concrete slab 2 and the bottom steel work part 1 shown in Fig. 1 combines;
2), during produce in factory, first make initial beam body section, be labeled as n piece, the beam body section that is labeled as n piece is also by becoming integrally-built top concrete slab 2 and bottom steel work part 1 to combine;
3), using the initial beam body section made as matching segment, build next beam body section, and next beam body section be labeled as to n+1 piece;
4), repeat previous step, make all beam body section of residue such as n+2, n+3 piece, the beam the body section subsequently ownership being performed is transported to bridge construction scene;
5), start beam body section installation procedure: first n piece beam body section is installed, complete after the CONSTRUCTION OF CABLE-STAYED BRIDGE concerned process steps of n piece beam body section, lift subsequently n+1 piece beam body section, after n+1 piece beam body section is debugged, the steel work part 1 of n+1 piece beam body section and n piece beam body section is welded to connect, the coupling face of the concrete slab 2 of n+1 piece beam body section and n piece beam body section is smeared epoxy glue, and the concrete slab 2 of n+1 piece beam body section and n piece beam body section stitches by splicing and is connected;
