Specific implementation mode
Such as Fig. 1 is simultaneously combined shown in Fig. 2 to Fig. 8, the big box-beam structure of precast concrete with the connection of wet seam direction across bridge, including
Construction pile foundation 1, cushion cap 2, column 3, construction bracket 4 and prefabricated components 5, the cushion cap 2 are mounted on the upper end of construction pile foundation 1, institute
The upper end that column 3 is mounted on cushion cap 2 is stated, the construction bracket 4 is mounted on the upper end of column 3, and the prefabricated components 5, which are placed on, to be applied
The upper end of work holder 4 is provided with steel reinforcement cage in the prefabricated components 5, and the prefabricated components 5 are provided with several precast sections 6, often
A precast section 6 is assemblied to form by web, bottom plate and top plate.
Further, it is provided with Cast-in-Situ Segment 7 between two neighboring precast section 6, each Cast-in-Situ Segment 7 is respectively connected with wet connect
Head mould plate, the steel reinforcement cage include bridge along bridge to the connection reinforcing bar between steel bar stress, stirrup and each prefabricated subsection.
Wherein, the prefabricated components 5 include 5 precast sections or 9 precast sections, and the construction pile foundation 1 is provided with several
A pile is formed with case hole 8 between two neighboring precast section 6.
The present invention builds the big box beam of concrete using the method for precast assembly, and compare cast-in-place structural, reduces scene
Duration reduces the influence of Construction on Environment, and beam sections mode precast assembly, component on site construction method spirit are used compared to larger box beam
