Abstract

The invention discloses a prefabricated double-T plate end connecting structure and a construction method thereof. The prefabricated double-T plate end connecting structure comprises angle steel connecting a prefabricated beam and a prefabricated double-T plate web, and a bridging connecting plate connecting adjacent flange plates, wherein a round hole and a horizontal long round hole are formed in the two side plate faces of the angle steel correspondingly; the other end of a threaded connecting piece penetrating through connecting holes in the two sides of the bridging connecting plate is positioned in a sleeve in a flange plate interlayer; the sleeve is anchored on a plate piece pre-buried in the flange plate interlayer; an anchoring steel bar pre-buried in the flange plate interlayer is fixed to the plate piece; a first tubular body matched with the round hole of the angle steel is pre-buried in the prefabricated beam; a second tubular body matched with the long round hole of the angle steel is pre-buried in a web interlayer; a first connecting bolt penetrates through the first tubular body; the two ends of the first connecting bolt penetrate through the round holes of the angle steel on the corresponding sides correspondingly and are connected through threaded fasteners; a second connecting bolt penetrates through the second tubular body; and the two ends of the second connecting bolt penetrate through the long round holes of the angle steel on the corresponding sides correspondingly and are connected through threaded fasteners.

Description

technical field [0001] The invention belongs to the field of civil engineering assembled buildings, and in particular relates to a prefabricated double T board end connection structure and a construction method thereof. Background technique [0002] Prefabricated double T panels have the characteristics of reasonable section force, large span, light weight, strong bearing capacity, high rigidity, and obvious economic advantages. Therefore, they are widely used in large-span and heavy-duty building structures such as industrial plants, commercial centers, and parking garages. . On the other hand, the connection between the end of the prefabricated double T-slab and the prefabricated structure has a great impact on the overall safety of the structure. [0003] At present, the prefabricated double T-slabs are usually placed directly on the outstretched corbels of the prefabricated beams, and are connected to the prefabricated beams at the top by lap joints of steel bars. This...
