The solplate's L (A + margin) runs across the 교각축 직각 and its W (B + margin) along the 교축; the top tapers across L with T1 at the (−) side (T1 = T + L·|S|/200). The 교량받침 본체 is one box per bearing: the solplate plan less 100 mm on each side, from the mortar top (EL.X) up h3 = 181 mm, turned with the bearing row. It is shown with the bearing group.

* 솔플레이트 기하 (승인 2026-10-23). Pure: the solplate of one bearing, from its block (position, rowSkew) and the

|
||
* The underside is the bearing top (block top EL.X + h3). Lengths in m, as in the model.
