Installation method of prefabricated stair
The invention discloses an installation method of a prefabricated stair. An upper stair beam comprises a first plane, a second plane and a first vertical face, and a lower stair beam comprises a third plane, a fourth plane and a second vertical face. The installation method comprises the following steps of (1) drawing an elevation control line, an X-direction control line and a Y-direction control line; (2) leveling on the second plane so as to form a first leveling layer, and leveling on the fourth plane so as to form a second leveling layer; (3) lifting the prefabricated stair, enabling the upper part of the prefabricated stair to fall on the first leveling layer and the lower part of the prefabricated stair to fall on the second leveling layer; (4) fastening and connecting the upper part of the prefabricated stair with the upper stair beam, and fastening and connecting the lower part of the prefabricated stair with the lower stair beam; and (5) filling the upper parts of the first plane and the third plane according to the elevation control line. All the steps cooperate so as to prevent inclination and displacement during installation of the prefabricated part, guarantee the reliable installation and construction quality of the prefabricated part, guarantee structural safety and avoid hidden dangers.
本发明公开了预制楼梯的安装方法。上梯梁包括第一平面、第二平面、第一立面，下梯梁包括第三平面、第四平面、第二立面，该安装方法包括以下步骤：(1)画出标高控制线、X向控制线、Y向控制线；(2)在第二平面上找平，形成第一找平层；在第四平面上找平，形成第二找平层；(3)吊装预制楼梯并使预制楼梯上部降落于第一找平层上、下部降落于第二找平层上；(4)将所述预制楼梯上部与上梯梁紧固连接，将所述预制楼梯下部与下梯梁紧固连接；(5)根据标高控制线对第一平面和第三平面上方进行填充。各个步骤协同作用，防止预制构件安装时发生的倾斜、位移，确保预制构件安装施工质量可靠，保证结构安全，不留隐患。
