腳手架搭設施工方案.doc

腳手架施工方案

1、腳手架施工要求：
搭設腳手架屬于登高作業，特別是外腳手架，它的高度是隨著建筑物或構筑物的施工進度而逐步上升，而且要超前于建筑物的施工進度。腳手架搭設的質量好壞影響工程進度和工程質量，如果搭設質量甚至會
導致倒塌事故造成人員傷亡和其它損失。因此，腳手架必須滿足如下要求：
(1)、堅固與穩定。在規定的施工載荷作用下，要求不搖晃、不傾斜、不下沉。
(2)、滿足施工要求。在滿足必要的材料、工具等物堆放的前提下，應保持通道平坦暢通無中斷。
(3)、給人以安全感，使施工人員上架后感到放心，無擔憂及害怕的心理。
2、基本名詞解釋：
(1)、雙排腳手架: 由內外兩排立桿和水平桿等構成的腳手架叫雙排腳手架，里排立桿一般離墻面40～50厘米，以便工人操作。內外兩排立桿之間的距離（即寬）為1.2米。
(2)、單排腳手架: 由一排立桿和水平桿等構成的腳手架叫單排腳手架，立桿離墻面為1.3m。單排腳手架一般用于三層以下建筑物的施工。
(3)、立桿：又叫站桿、沖天桿，就是腳手架中垂直于水平面的豎向桿件。立桿有外立桿、內立桿、交桿之分，其中外立桿為雙排腳手架中離開結構物一側的立桿，或單排架立桿；內立桿為雙排腳手架中貼近墻體一側的立桿；角桿為位于腳手架轉角處的立桿。立桿的作用是將縱向、橫向水平桿傳來的荷載垂直傳到地基上。它是腳手架的主要受力桿，立桿的強度和剛度，對整個腳手架的穩定和安全起著重要的作用。立桿的縱向間距應視其荷載的大小和使用情況來決定。砌筑時，荷載較大（每平方米約270公斤，集中荷載每平方米約150公斤），其間距一般為1.3米；裝飾用時，荷載較小，可增大間距至1.5米。
(4)、縱向水平桿：沿腳手架縱向設置的水平
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
