Cantilever plate external corner reinforcement construction method
The invention discloses a cantilever plate external corner reinforcement construction method. The method comprises the following steps that 1, a formwork is erected for a cantilever plate; 2, short steel bars on the upper skin of the external corner are laid; 3, long-direction steel bars, perpendicular to the short-direction steel bars, of the external corner upper skin are laid; 4, binding bidirectional steel bars at the intersection points; 5, determining the thickness of a concrete protection layer of the length-direction reinforcing steel bars according to different environment types; and 6, concrete is poured. According to the construction method, the structure is simple and clear; construction is easy, and the steel bar amount is easy to calculate; the concrete protection layer of the negative reinforcement cannot be enlarged due to the radiation reinforcement; when no plate exists in the corner chamber, the negative reinforcement can be anchored into the edge beam; radial ribs are omitted, the configuration range of bidirectional distribution ribs is reduced, the arrangement range of bidirectional negative ribs is extended to the outer edge of the cantilever plate, and the length type of the negative ribs cannot be increased; the stress ribs are allowed to be lapped, and when the cantilever length of the cantilever slab is large, the bidirectional negative ribs can be lapped in a staggered mode.
本发明公开了悬挑板阳角配筋施工方法，包括如下步骤：步骤1：为悬挑板支模；步骤2：铺设阳角上皮的短向钢筋；步骤3：铺设阳角上皮与短向钢筋垂直的长向钢筋；步骤4：在交点处绑扎双向钢筋；步骤5：根据环境类别的不同，确定长向钢筋的混凝土保护层厚度；步骤6：浇筑混凝土。本发明的施工方法构造简单明了；容易施工，计算钢筋量也很简单；负筋的混凝土保护层不会因为放射筋而加大；当角部室内无板时，可将负筋锚入边梁中；取消了放射筋，减少了双向分布筋的配置范围，把双向负筋的布置范围延长至悬挑板的外缘，不会增加负筋的长度类型；受力筋是允许搭接的，当悬臂板悬挑长度较大时，双向负筋也可以错位搭接。
