不同類型的工程施工選用不同用途的移動(dòng)腳手架和模板支架。目前，橋梁支撐架使用碗扣腳手架的居多，也有使用門式腳手架的。主體結(jié)構(gòu)施工落地腳手架使用扣件腳手架的居多，移動(dòng)腳手架立桿的縱距一般為1.2~1.8m；橫距一般為0.9~1.5m?？奂戒摴苣_手1：優(yōu)點(diǎn) 1) 承載力較大。當(dāng)移動(dòng)腳手架的幾何尺寸及構(gòu)造符合規(guī)范的有關(guān)要求時(shí)，一般情況下，移動(dòng)腳手架的單管立柱的承載力可達(dá)15kN～35kN(1．5tf～3．5tf，設(shè)計(jì)值)。 2)裝拆方便，搭設(shè)靈活。由于鋼管長(zhǎng)度易于調(diào)整，扣件連接簡(jiǎn)便，因而可適應(yīng)各種平面、立面的建筑物與構(gòu)筑物用門式腳手架。 3)比較經(jīng)濟(jì)。加工簡(jiǎn)單，一次投資費(fèi)用較低；如果精心設(shè)計(jì)門式腳手架幾何尺寸，注意提高鋼管周轉(zhuǎn)使用率，則材料用量也可取得較好的經(jīng)濟(jì)效果?？奂摴芗苷酆厦科椒矫捉ㄖ娩摿考s15公斤。

Scaffolds and formwork supports are chosen for different types of engineering construction. At present, most of the bridge support frames are bowl buckles and scaffolding. In the construction of main structure, fastener scaffolding is mostly used. The longitudinal distance of scaffolding poles is generally 1.2-1.8 m, and the transverse distance is generally 0.9-1.5 M. Fastener type steel pipe foot 1: advantages 1) large bearing capacity. When the scaffolding geometry and structure meet the relevant requirements of the code, in general, the bearing capacity of the scaffolding single pipe column can reach 15 kN-35 kN (1.5 tf-3.5 tf, design value). 2) easy installation and installation. Because the length of steel pipe is easy to adjust and the connection of fasteners is simple, it can be used in scaffolding of buildings and structures with various planes and elevations. 3) Comparative economy. The processing is simple and the cost of one-time investment is low. If the scaffolding geometry size is carefully designed and the turnover utilization rate of steel pipe is improved, the material consumption can also achieve better economic results. The steel pipe rack of the fastener is equivalent to 15 kilograms of steel per square metre.

2：缺點(diǎn) 1)扣件(特別是它的螺桿)容易丟失； 2)節(jié)點(diǎn)處的桿件為偏心連接，靠抗滑力傳遞荷載和內(nèi)力，因而降低了其承載能力； 3)扣件節(jié)點(diǎn)的連接質(zhì)量受扣件本身質(zhì)量和工人操作的影響顯著。

2: Disadvantage 1) Fasteners (especially its screw) are easily lost; 2) the rods at the joints are eccentrically connected, which transfer loads and internal forces by anti-sliding force, thus reducing their bearing capacity; 3) the quality of the connection of fastener joints is significantly affected by the quality of fasteners themselves and the operation of workers.

碗扣式鋼管腳手架

Bowl buckle steel pipe scaffold

1：優(yōu)點(diǎn) 1)多功能：能根據(jù)具體施工要求，組成不同組架尺寸、形狀和承載能力的單、雙排腳手架，支撐架，支撐柱，物料提升架，爬升腳手架，懸挑架等多種功能的施工裝備。也可用于搭設(shè)施工棚、料棚、燈塔等構(gòu)筑物。特別適合于搭設(shè)曲面腳手架和重載支撐架。 2)高功效：常用桿件中最長(zhǎng)為3130mm，重17.07kg。整架拼拆速度比常規(guī)快3～5倍，拼拆快速省力，工人用一把鐵錘即可完成全部作業(yè)，避免了螺栓操作帶來(lái)的諸多不便。 3)通用性強(qiáng)：主構(gòu)件均采用普通的扣件式鋼管腳手架之鋼管，可用扣件同普通鋼管連接，通用性強(qiáng)。 4)承載力大：立桿連接是同軸心承插，橫桿同立桿靠碗扣接頭連接，接頭具有可靠的抗彎、抗剪、抗扭力學(xué)性能。而且各桿件軸心線交于一點(diǎn)，節(jié)點(diǎn)在框架平面內(nèi)，因此，結(jié)構(gòu)穩(wěn)固可靠，承載力大。（整架承載力提高，約比同等清況的扣件式鋼管腳手架提高15％以上，） 5)安全可靠：接頭設(shè)計(jì)時(shí)，考慮到上碗扣螺旋摩擦力和自重力作用，使接頭具有可靠的自鎖能力。作用于橫桿上的荷載通過(guò)下碗扣傳遞給立桿，下碗扣具有很強(qiáng)的抗剪能力(最大為199kN)。上碗扣即使沒(méi)被壓緊，橫桿接頭也不致脫出而造成事故。同時(shí)配備有安全網(wǎng)支架，間橫桿，腳手板，擋腳板，架梯。挑粱．連墻撐等桿配件，使用安全可靠。 6)易于加工：主構(gòu)件用Φ48×3.5、Q 235焊接鋼管，制造工藝簡(jiǎn)單，成本適中，可直接對(duì)現(xiàn)有扣件式腳手架進(jìn)行加工改造．不需要復(fù)雜的加工設(shè)備。 7)不易丟失：該腳手架無(wú)零散易丟失扣件，把構(gòu)件丟失減少到最小程度。 8)維修少：該腳手架構(gòu)件消除了螺栓連接．構(gòu)件經(jīng)碰耐磕．一般銹蝕不影響拼拆作業(yè)，不需特殊養(yǎng)護(hù)、維修。 9)便于管理：構(gòu)件系列標(biāo)準(zhǔn)化，構(gòu)件外表涂以橘黃色。美觀大方，構(gòu)件堆放整齊，便于現(xiàn)場(chǎng)材料管理，滿足文明施工要求。 10)易于運(yùn)輸：該腳手架最長(zhǎng)構(gòu)件3130mtm，最重構(gòu)件40.53kg，便于搬運(yùn)和運(yùn)輸。

2：缺點(diǎn) 1)橫桿為幾種尺寸的定型桿，立桿上碗扣節(jié)點(diǎn)按0.6m間距設(shè)置，使構(gòu)架尺寸受到限制； 2)U形連接銷易丟； 3)階格較貴； 3.3.3適應(yīng)性 1)構(gòu)筑各種形式的腳手架、模板和其它支撐架； 2)組裝井字架； 3)搭設(shè)坡道、工棚、看臺(tái)及其它臨時(shí)構(gòu)筑物； 4)構(gòu)造強(qiáng)力組合支撐柱； 5)構(gòu)筑承受橫向力作用的支撐架；
