The design of stone crafts needs to adapt to the bridge shape, and stone crafts should be regarded as a part of the whole bridge shape. While choosing the form of the bridge, the corresponding stone art form should also be considered. The shape of stone crafts should not be the same as that of the bridge structure. For example, when the bridge body is arch-shaped, the form of stone art should adopt the form assembled by straight plate parts as far as possible, and use less or no arc components.
Because when the bridge body is arch-shaped, there are often many abdominal arches on the main arch, and then the curved stone art is the same as the bridge body; At this time, the shape of the stone art should balance and coordinate the shape of the bridge body. Instead of adopting the form of oblique lines, denser vertical stone art should be used, or light solid boards should be used to avoid Similar to the analysis frame.
For beam and slab bridges, since the main lines constituting the bridge body are mostly horizontal lines except for piles and abutments, in order to avoid being similar to the bridge body, the shape of stone crafts should be mainly vertical lines, or occasionally curves and arcs form. The shape of stone crafts should avoid trivial and messy.
There are three reasons for the trivial and messy stone art: one is that it cannot match the form of the bridge, and the stone art form is chosen arbitrarily. The second is that there are too many decorations and carvings in the stone art itself, and some decorations may become superfluous and self-defeating. The third is that the various boards that make up the stone art are too small and dense.
For bridges with wide decks, medians, two-lane or four-lane bridges. The shape of the stone art should be solemn, stable and elegant, and the cross-sectional size of each part of the stone art should be appropriately increased so that the ratio of the width of the bridge deck to the width of the stone art is appropriate. If it is too big, it will be cumbersome, if it is too small, it will be bulky and light-headed, and it will lose its balance. For narrow and long bridges, the shape of stone crafts should be simple, crisp and smooth.
