Construction method for adding elevator to existing building
The invention belongs to the field of adding elevators to existing buildings, and provides a construction method for adding elevators to existing buildings, which comprises the following steps: S1, arranging pile foundations under the ground of a first floor of an original staircase rest platform stairway beam or arranging a ground beam as a foundation of a combined steel column by using an original foundation, and constructing the combined steel column, the combined steel columns are used for supporting ladder way beams of all layers of rest platforms; s2, top heightening parts of ladder way beams of all layers of rest platforms are constructed; s3, after concrete of the heightened part reaches certain strength, beam concrete below the bottom of an ascending step plate is chiseled away, original beam stirrups are protected by powder cement mortar after being bent, and the elevation of the beam bottom is improved; the rest platform stairway beam is supported by the combined steel columns, the top of the stairway beam is heightened and reinforced at the ascending step section, stairway beam concrete below the ascending step plate bottom is chiseled away, beam bottom clearance heightening is achieved, then the original stairway beam bottom clearance height meets the standard requirement, and the slope ramp is smaller than 1: 3.2.
本发明属于既有建筑加装电梯领域，提供了一种既有建筑加装电梯的施工方法，包括以下步骤：S1，在原楼梯间休息平台梯口梁的一层地面下设置桩基或利用原基础设置地梁作为组合钢柱的基础，施工组合钢柱，组合钢柱用于支撑各层休息平台梯口梁；S2，施工各层休息平台梯口梁顶部加高部分；S3，待此加高部分混凝土达一定强度后凿除上行踏步板底以下梁混凝土，原梁箍筋弯折后粉水泥砂浆保护，实现梁底标高提高；本发明通过利用组合钢柱支撑休息平台梯口梁，在上行踏步段对梯口梁顶部进行加高加固，凿除上行踏步板底以下的梯口梁混凝土，实现梁底净空加高，进而使得原梯口梁底净空高度满足规范要求和斜坡坡道小于1:3.2。
