竹脚手架搭设安全技术交底
一、 一般规定：
二、     ⒈选材：使用生长四年以上的毛竹，青嫩、枯黄、虫蛀、腐烂，裂缝（透节二节以上）不得使用。
⒉绑扎：使用水葱竹篾、广篾。不得一扣绑三根。
 ⒊毛竹直径：立杆、大横杆、剪刀撑、抛撑、顶撑的小头有效直径应≥7cm。横担（小横杆）≥9cm。
 ⒋架子高度在24m以内，24m以上应有编制设计方案和审批。
  ⒌砌筑脚手架上的均布荷载不得超过270kg/m2 ，装饰脚手架上的均布荷载不得超过200kg/m2 。
三、 立杆：
⒈放样：脚手架搭设范围内的地基要整平夯实。
    ⑴  根据施工员的交底和建筑物的特点，确定立杆纵、横向间距，现场拉线，钉竹签放样。
    ⑵  根据建筑物的总高度和特点及施工要求确定架子的步距（应≤1.8），以及第一皮架子的高度。
    ⒉埋深30～50cm，下垫砧石，土质松软或挖坑有困难时，要绑扫地杆。
    ⒊横向间距：1～1.2m，里立杆离墙≤20cm。
    ⒋纵向间距：1.3～1.5m（误差土5cm）。超过15m高的架子立杆间距不得大于1.5m。外立杆应高出屋面1.2～1.5m。
    ⒌垂直度：转角处≤10cm，架子中间≤15cm。
    ⒍立杆搭接长度：不小于1.8m，而且接头要跨过一
Bamboo Scaffolding Safety Technology Details
I. General provisions:
Second, ⒈ selection: the growth of more than four years using bamboo, green and tender, yellow, insects, rot, crack (through section 2 above) shall not be used.
⒉ Binding: Use Shuicong Bamboo, bamboo wide. A deduction shall not be tied three.
 ⒊ bamboo diameter: pole, a large bar, bridging, bracing, roof support effective diameter of the small head should be ≥ 7cm. Cross arms (small bar) ≥ 9cm.
 ⒋ shelf height less than 24m, 24m or more should be the preparation of design and approval.
  ⒌ masonry scaffolding on the uniform load must not exceed 270kg/m2, decorative scaffolding on a uniformly distributed load shall not exceed 200kg/m2.
3, Pole:
⒈ Setting: Scaffolding within the compacted foundation to leveling.
    ⑴ members under the classification of components and construction features of the building to determine the pole vertical and horizontal spacing, live wires, nails bamboo lofting.
    ⑵ according to the total height of the building and construction requirements and characteristics determine the shelf of Step (should be ≤ 1.8), and the first skin shelf height.
    ⒉ depth of 30 ~ 50cm, Xiadian anvil stone, loose soil, or digging a difficulty, to tie sweep shot.
    ⒊ horizontal distance: 1 ~ 1.2m, in pole away from the wall ≤ 20cm.
    ⒋ vertical distance: 1.3 ~ 1.5m (error soil 5cm). More than 15m high pole shelf spacing no larger than 1.5m. Outside the pole above the roof should be 1.2 ~ 1.5m.
    ⒌ verticality: the corner ≤ 10cm, middle shelf ≤ 15cm.
    ⒍ Pole Lap length: not less than 1.8m, and a connector to be taken
