Embodiment 1
[0041] see figure 1 , 2, 3, 4, a kind of cast-in-place arch bridge bar support steel arc-shaped distribution beam structure of the present invention, described structure replaces the wooden arch beam structure in the cast-in-place arch bridge, and supports the construction of the whole arch bridge; the structure consists of Several sections of arc-shaped distribution beams 1 are connected, and a wedge-shaped seat 4 is provided under the arc-shaped distribution beam 1, which is placed on the adjustable jacking 6 on the top of the pole-type full hall support 7; an anti-skid block is arranged above the arc-shaped distribution beam 1 5. Prevent the upper lateral distribution beam from sliding.
[0042] Said construction is made of steel material.
[0043] The curved distribution beam 1 is formed by bending I-shaped steel.
[0044] Flanges 2 are installed at both ends of the arc-shaped distribution beam 1 , through which the sections of the arc-shaped distribution beam 1 are butt...
