竹腳手架搭設(shè)安全技術(shù)交底
一、 一般規(guī)定：
二、     ⒈選材：使用生長四年以上的毛竹，青嫩、枯黃、蟲蛀、腐爛，裂縫（透節(jié)二節(jié)以上）不得使用。
⒉綁扎：使用水蔥竹篾、廣篾。不得一扣綁三根。
 ⒊毛竹直徑：立桿、大橫桿、剪刀撐、拋撐、頂撐的小頭有效直徑應(yīng)≥7cm。橫擔(dān)（小橫桿）≥9cm。
 ⒋架子高度在24m以內(nèi)，24m以上應(yīng)有編制設(shè)計(jì)方案和審批。
  ⒌砌筑腳手架上的均布荷載不得超過270kg/m2 ，裝飾腳手架上的均布荷載不得超過200kg/m2 。
三、 立桿：
⒈放樣：腳手架搭設(shè)范圍內(nèi)的地基要整平夯實(shí)。
    ⑴  根據(jù)施工員的交底和建筑物的特點(diǎn)，確定立桿縱、橫向間距，現(xiàn)場拉線，釘竹簽放樣。
    ⑵  根據(jù)建筑物的總高度和特點(diǎn)及施工要求確定架子的步距（應(yīng)≤1.8），以及第一皮架子的高度。
    ⒉埋深30～50cm，下墊砧石，土質(zhì)松軟或挖坑有困難時(shí)，要綁掃地桿。
    ⒊橫向間距：1～1.2m，里立桿離墻≤20cm。
    ⒋縱向間距：1.3～1.5m（誤差土5cm）。超過15m高的架子立桿間距不得大于1.5m。外立桿應(yīng)高出屋面1.2～1.5m。
    ⒌垂直度：轉(zhuǎn)角處≤10cm，架子中間≤15cm。
    ⒍立桿搭接長度：不小于1.8m，而且接頭要跨過一
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
