Erecting method for formwork supporting frame of overhanging platform on upper portion of ramp opening
The invention discloses a ramp opening upper cantilever platform formwork supporting frame erecting method, and belongs to the technical field of building construction.The ramp opening upper cantilever platform formwork supporting frame erecting method comprises a main supporting frame, roof uniform-section steel beams or rented finished H-shaped steel are utilized, one side of each steel beam is erected on the surface of a concrete structure, and the other side of each steel beam is erected on the upper portion of a slope; the steel beams are connected into a whole through bolts. A steel beam end erected on the side slope is fixed through a temporary fixing support and is aligned and leveled, then a formwork is erected on the lower portion, concrete is poured, and the concrete strength and the contact face compactness are guaranteed; the formwork supporting frame bodies are arranged through modeling software, the positions of the vertical rods are determined, and marking is conducted on the upper surface of the steel beam; then, a 16 # I-shaped steel small cross beam is erected; fixing the small cross beam and the upper flange of the steel beam by adopting a fixing device; and finally, the whole frame body is erected. Aiming at the conditions that the soil texture of the ramp opening is soft and the bearing capacity of the foundation cannot meet the requirements, the existing resources are fully utilized, the cost is saved, the problem that the template support frame of the cantilever platform at the upper part of the ramp opening cannot root is effectively solved, the erection working efficiency is improved, the stability of the frame body is ensured, the construction period is shortened, and the engineering cost is reduced.
本发明公开了一种坡道口上部悬挑平台模板支撑架搭设方法，属于建筑施工技术领域，包括主支撑框架，利用屋面等截面钢梁或者租赁成品H型钢，钢梁一侧架设在混凝土结构表面，另外一侧搭设在边坡上部；钢梁之间采用螺栓连接形成一个整体；搭设在边坡上的钢梁端采用临时固定支架固定，找正、找平后下部支设模板浇筑混凝土，确保混凝土强度和接触面密实；利用建模软件对模板支撑架体进行排布，确定立杆的位置，在钢梁上表面划线标记；然后架设16#工字钢小横梁；采用固定装置将小横梁与钢梁上翼缘进行固定；最后进行整个架体的搭设。本发明针对坡道口土质松软，地基承载力不能满足要求的情况，充分利用现有资源，节约成本，有效的解决了坡道口上部悬挑平台模板支撑架无法生根的问题，提高了搭设工作效率，保证了架体稳定性，缩短了施工工期，降低了工程成本。
