            樓梯施工要點
            (1)基層表面的浮土和砂漿應清理干凈,若有油污,應用10%火堿水刷凈,并用壓力水沖洗干凈。同時,須清理踏步板、休息板基層表面地墻相交的陰角處,以及踢腳板處的墻面,且將落地灰漿和影響面層厚度的凸出部位剔鑿平整。
            (1) the floated soil and mortar should be cleaned up. If there is oil pollution, wash it with 10% caustic soda water and rinse it with pressure water. At the same time, it is necessary to clean down the treadle, the negative corner of the surface of the floor of the rest plate, and the wall of the kicking board, and make the ground grout and the protruding parts of the thickness of the surface layer cut off.
            (2)墊好保護層墊塊后應開始安裝梁側模,用梁側模夾住梁底模,且底模與側模接縫處貼海綿條擠嚴,以防漏漿。然后在梯梁側模上標出梯板蓋筋和底部通長鋼筋的位置,并插入蓋筋進行臨時固定。
            (2) Liang Cemo should be installed after the cushion is well placed, and the bottom die of the beam is clamped with the side die of the beam, and the sponge bar is attached to the joint of the bottom die and the side die to prevent the leakage of the slurry. Then mark the gangboard cover and bottom reinforcement position in long steel ladder beam side, and insert the cover fixed temporary reinforcement.
            (3)鋼筋預埋時應控制鋼筋外露長度,其中長筋與短筋接頭百分率按50%考慮,外露長度為短鋼筋直徑20倍,長鋼筋直徑35倍。
            (3) the length of steel reinforcement should be controlled when the reinforcement is preburied. The percentage of the long and short reinforcement is considered by 50%, the length is 20 times the diameter of the short bar, and the diameter of the long steel bar is 35 times.
            (4)澆筑混凝土時應控制結構尺寸和澆筑標高,并先振實底板部分,達到踏步位置后將踏步混凝土一同澆搗,再自下而上逐一澆筑,同時適當減小樓梯混凝土坍落度。
            (4) when the concrete is poured, the size of the structure and the elevation should be controlled, and the floor part should be vibrated first. After the step, the concrete should be poured together and then pouring from the bottom to the top. At the same time, the slump of the concrete staircase is reduced.
