Formwork support for large cantilever bent cap of rectangular pier column
The invention discloses a rectangular pier column large cantilever bent cap formwork support which comprises two main cross beams located on the front side and the rear side of a pier column respectively, each main cross beam is of a double-cantilever multi-span continuous beam structure, and each main cross beam is provided with two side supporting points and at least two middle supporting points located between the two side supporting points. The arrangement structure of the fulcrums needs to meet the following conditions that the maximum value of the sagging moment absolute value of the main cross beam is equal to or close to the maximum value of the hogging moment absolute value, so that the hogging moment borne by the main cross beam and the stress borne by a single fulcrum are small, and the structural size of the main cross beam and the structural size of the triangular bracket are reduced; the side supporting points are supported by triangular brackets, the triangular brackets are fixed on the pier columns, distribution beams are laid on the two main cross beams, and chamfering bottom die supports are fixed on the distribution beams. The device is simple in structure, small in size and convenient to mount and dismount, the construction efficiency can be improved, and the construction cost is reduced; the influence of the height of the pier column and the ground condition below the bent cap is avoided.
本发明公开了一种矩形墩柱大悬臂盖梁模板支架，包括分别位于墩柱前后两侧的两根主横梁，主横梁采用双悬臂多跨连续梁结构，设有两个侧支点和位于两个侧支点之间的至少两个中间支点，且支点的布置结构需要满足以下条件：主横梁正弯矩绝对值的最大值与负弯矩绝对值的最大值相等或接近，进而使主横梁所受负弯矩及单个支点受力较小，减小主横梁构造尺寸及三角形托架构造尺寸，中间支点通过牛腿固定在墩柱上，侧支点由三角形托架支撑，三角形托架固定在墩柱上，在两根主横梁上铺设有分配梁，在分配梁上固定有倒角底模支架。本发明结构简单，尺寸小，安装及拆卸便捷，能够提高施工效率，降低施工成本；不受墩柱高度及盖梁下方地面情况的影响。
