a bridge penetrating floor plate connecting structure comprises a pre-buried joint and a connecting piece, wherein the pre-buried joint is used for a bridge to penetrate through, is of a tubular structure, is fixedly embedded in a cast-in-place concrete structure floor slab, and is communicated with spaces on two sides of the cast-in-place concrete structure floor slab through the pre-buried joint;

the connecting piece is arranged between the embedded connector and the bridge and fixedly connected with the embedded connector and the bridge through bolt penetration fit.

Adopt above-mentioned technical scheme's utility model, through tubular structure's pre-buried mode of connecting, for the crane span structure provides standardized installation passageway, and pre-buried joint is as the partly of the building body, exempts from to demolish, and through the connection piece with pre-buried joint and crane span structure fixed connection's mode, improve the construction step into one shot forming construction method, guaranteed the shaping quality and the impression quality of crane span structure more.

Further inject, buried joint both ends all are equipped with the turn-ups that turns over outwards, and the turn-ups can regard as with the injecing of cast-in-place concrete structure floor both sides face, improve mounting structure's stability, simultaneously, also can pour when fixed, as with pour the connection limit between the template, produce the displacement during the construction, improve the construction precision.

Further limit, it has a plurality of first bolt holes to open on the connecting piece, the construction installation of being convenient for.

Further inject, it has a plurality of second bolt holes to open on the embedded joint lateral wall, the construction installation of being convenient for.

Compared with the prior art, the utility model, with pre-buried joint and crane span structure fixed connection's mode through the connection piece, improve the construction procedure into one shot forming construction method, guaranteed the shaping quality and the impression quality of crane span structure more.
