Anti-cracking structure for box girder in girder storage period
The invention relates to a box girder storage period anti-cracking structure which comprises a box girder and a support, a supporting cavity is formed in the box girder, a web plate is arranged in the supporting cavity, and the plane where the web plate is located is parallel to the width direction of the box girder; the number of the supports is at least three, the at least three supports are arranged on the side face, facing the ground, of the box girder, the positions, on the box girder, of the three supports can define a triangle, and the position, on the box girder, of one support is located in the plane where the web is located. And the web can provide support for the cavity structure of the box girder in the supporting cavity. A support is arranged at the position, corresponding to the plane where the web is located, of the side face, facing the ground, of the box girder, and stable supporting and protection are further provided for the overall structure of the box girder. Wherein a triangle is defined by the three supports, so that the stress safety of the box girder in the girder storage period is guaranteed, cracks in the girder storage period are avoided, meanwhile, deformation in the girder storage period can be reduced, and then the butt joint difficulty during hoisting of the box girder is reduced.
本发明涉及一种箱梁存梁期防开裂结构，包括箱梁和支座，所述箱梁内形成有支撑腔，所述支撑腔内设置有腹板，所述腹板所在平面与所述箱梁的宽度方向平行；所述支座的数量为至少三个，至少三个所述支座设置在所述箱梁朝向地面的一侧面上，其中三个所述支座在所述箱梁上的位置能够围成三角形，且其中一个支座在箱梁上的位置位于所述腹板所在平面内。腹板能够在支撑腔内为箱梁的腔体结构提供支撑。在箱梁朝向地面的一侧面上，腹板所在平面对应的位置设置支座，进一步为箱梁整体结构提供稳定的支撑和防护。其中三个支座围成三角形保证箱梁在存梁期间的受力安全，避免产生存梁期裂缝，同时还可以减小存梁期的变形，进而降低箱梁吊装时候的对接难度。
