脚手架搭设施工方案.doc

脚手架施工方案

1、脚手架施工要求：
搭设脚手架属于登高作业，特别是外脚手架，它的高度是随着建筑物或构筑物的施工进度而逐步上升，而且要超前于建筑物的施工进度。脚手架搭设的质量好坏影响工程进度和工程质量，如果搭设质量甚至会
导致倒塌事故造成人员伤亡和其它损失。因此，脚手架必须满足如下要求：
(1)、坚固与稳定。在规定的施工载荷作用下，要求不摇晃、不倾斜、不下沉。
(2)、满足施工要求。在满足必要的材料、工具等物堆放的前提下，应保持通道平坦畅通无中断。
(3)、给人以安全感，使施工人员上架后感到放心，无担忧及害怕的心理。
2、基本名词解释：
(1)、双排脚手架: 由内外两排立杆和水平杆等构成的脚手架叫双排脚手架，里排立杆一般离墙面40～50厘米，以便工人操作。内外两排立杆之间的距离（即宽）为1.2米。
(2)、单排脚手架: 由一排立杆和水平杆等构成的脚手架叫单排脚手架，立杆离墙面为1.3m。单排脚手架一般用于三层以下建筑物的施工。
(3)、立杆：又叫站杆、冲天杆，就是脚手架中垂直于水平面的竖向杆件。立杆有外立杆、内立杆、交杆之分，其中外立杆为双排脚手架中离开结构物一侧的立杆，或单排架立杆；内立杆为双排脚手架中贴近墙体一侧的立杆；角杆为位于脚手架转角处的立杆。立杆的作用是将纵向、横向水平杆传来的荷载垂直传到地基上。它是脚手架的主要受力杆，立杆的强度和刚度，对整个脚手架的稳定和安全起着重要的作用。立杆的纵向间距应视其荷载的大小和使用情况来决定。砌筑时，荷载较大（每平方米约270公斤，集中荷载每平方米约150公斤），其间距一般为1.3米；装饰用时，荷载较小，可增大间距至1.5米。
(4)、纵向水平杆：沿脚手架纵向设置的水平
Scaffolding construction plan

1, scaffold construction requirements:
Scaffold erection jobs are climbing, especially outside the scaffold, it is the height of the building or structure with the construction schedule and gradually increase, but also to advance the progress of the construction of the building. Scaffolding The quality of the works progress and quality, even if the erection quality
Led to the collapse of casualties and other losses. Therefore, the scaffold must meet the following requirements:
(1), rigidity and stability. The required construction loads, asked not to be shaken, not tilt, do not sink.
(2), to meet the construction requirements. To meet the necessary materials, tools and other items piled up under the premise should be kept flat channel flow without interruption.
(3), gives a sense of security, so that construction workers feel at ease after the shelves, no worries and fear of the psychological.
2, the basic terms explained:
(1), double scaffolding: two rows from the outside pole and the horizontal bar and other form of scaffolding is called double scaffolding pole in row away from the wall generally 40 to 50 cm for workers to operate. Inside and outside the distance between two rows of pole (or width) of 1.2 meters.
(2), single row of scaffolding: a line from the pole and the horizontal bar so called single-row form the scaffolding scaffolding pole away from the wall to 1.3m. Scaffolding is generally used a single row of the following three building construction.
(3) Pole: also known as Station bar, sky bar, that is, perpendicular to the horizontal scaffold in the vertical bars. Pole of an outer pole, which pole, cross bar of the points, double scaffolding outside pole for the structure in the left side of the pole, or single-bent pole; within the pole is close to double Scaffold wall side of the pole; angle shot for the pole at the corner of the scaffolding. The role of pole is vertical, horizontal bar horizontal vertical spread the load came on the ground. It is the main force scaffolding pole, pole strength and stiffness of the whole scaffolding of stability and security plays an important role. Vertical pole spacing should be considered the size of its load and use to decide. Masonry, the load is large (about 270 kilograms per square meter, concentrated load of about 150 kilograms per square meter), the spacing is generally 1.3 m; decorative, the loads small, can increase the distance to 1.5 meters.
(4), vertical horizontal bar: along the longitudinal level of scaffolding
