    脚手架的品种及各自特性

    2018-11-10 09:11:24 无锡盛发地坪科技有限公司 阅读

    扣件式脚手架1、优点1)承载力较大。当脚手架的几何尺寸及构造符合规范的有关要求时,一般情况下,脚手架的单管立柱的承载力可达15kN~35kN(1.5tf~3.5tf,设计值)。2)装拆方便,搭设灵活。由于钢管长度易于调整,扣件连接简便,因而可适应各种平面、立面的建筑物与构筑物用移动脚手架。 3)比较经济,加工简单,一次投资费用较低;如果精心设计移动脚手架几何尺寸,注意提高钢管周转使用率,则材料用量也可取得较好的经济效果。扣件钢管架折合每平方米建筑用钢量约15公斤。 Fastener scaffold 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) It is economical, simple to process and low cost of one-time investment. If the scaffolding geometry is carefully designed and the turnover utilization rate of steel tube 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、缺点 2. Shortcomings 1)扣件(特别是它的螺杆)容易丢失; 1) fastener (especially its screw) is easy to lose. 

    螺栓拧紧扭力矩不应小于40N·m,且不应大于65N·m;[1] The tightening torque of bolts should not be less than 40N. M, and should not be greater than 65N. M; [1] 

    2)节点处的杆件为偏心连接,靠抗滑力传递荷载和内力,因而降低了其承载能力; 2) The member at the joint is eccentrically connected, which transfers load and internal force by anti-sliding force, thus reducing its bearing capacity. 

    3)扣件节点的连接质量受扣件本身质量和工人操作的影响显著。 3) the connection quality of fastener nodes is significantly affected by the quality of the fastener itself and the operation of workers. 

    3、适应性 3, adaptability 

    1)构筑各种形式的门式脚手架、模板和其它支撑架; 1) to build scaffolding, formwork and other supporting frames in various forms. 

    2)组装井字架; 2) assemble well frame; 

    3)搭设坡道、工棚、看台及其它临时构筑物, 3) erect ramps, shed, bleachers and other temporary structures. 

    4)作其它种门式脚手架的辅助,加强杆件; 4) assist other kinds of scaffolds to strengthen the rods. 

    4、搭设要求 4. Erection requirements 

    钢管扣件梯形脚手架搭设中应注意地基平整坚实,设置底座和垫板,并有可靠的排水措施,防止积水浸泡地基。 In the construction of scaffolding with steel pipe fasteners, attention should be paid to the smooth and solid foundation, the base and cushion plate should be set up, and reliable drainage measures should be taken to prevent the foundation from being immersed in water. 

    根据连墙杆设置情况及荷载大小,常用敞开式双排梯形脚手架立杆横距一般为1.05~1.55m,砌筑脚手架步距一般为1.20~1.35m,装饰或砌筑、装饰两用的脚手架一般为1.80m,立杆纵距1.2~2.0m。其允许搭设高度为34~50m。当为单排设置时,立杆横距1.2~1.4 m,立杆纵距1.5~2.0m。允许搭设高度为24m。 According to the setting of connecting rod and the load, the common open double row scaffolding vertical spacing is generally 1.05-1.55m, the masonry scaffolding step spacing is generally 1.20-1.35m, the decorative or masonry scaffolding is generally 1.80m, and the vertical spacing of the vertical pole is 1.2-2.0m. Its permitted height is 34~50m. When it is set for single row, the vertical distance is 1.2~1.4 m and the vertical pole is 1.5~2.0m. The height is allowed to be 24m. 

    纵向水平杆宜设置在立杆的内侧,其长度不宜小于3跨,纵向水平杆可采用对接扣件,也可采用搭接。如采用对接扣件方法,则对接扣件应交错布置;如采用搭接连接,搭接长度不应小于1 m,并应等间距设置3个旋转扣件固定。 Longitudinal horizontal bar should be set in the inner side of the vertical bar, and its length should not be less than 3 spans. Longitudinal horizontal bar can use butt fasteners or lap joints. If the butt fastener method is adopted, the butt fastener shall be staggered; if the lap connection is adopted, the lap length shall not be less than 1 m, and three rotating fasteners shall be fixed at equal intervals. 

    脚手架主节点(即立杆、纵向水平杆、横向水平杆三杆紧靠的扣接点)处必须设置一根横向水平杆用直角扣件扣接且严禁拆除。主节点处两个直角扣件的中心距不应大于150mm。在双排脚手架中,横向水平杆靠墙一端的外伸长度不应大于立杆横距的0.4倍,且不应大于500mm;作业层上非主节点处的横向水平杆,宜根据支承脚手板的需要等间距设置,最大间距不应大于纵距的1/2。 The main joints of scaffolding (i.e. the vertical bar, the vertical horizontal bar and the buckle point close to the horizontal bar) must be connected by a horizontal bar with a right angle fastener and must not be dismantled. The center distance between the two right angle fasteners at the main node should not be greater than 150mm. In double-row scaffolding, the extension length of the lateral horizontal bar at the end of the wall should not be greater than 0.4 times of the vertical bar's transverse distance, and should not be greater than 500 mm. The transverse horizontal bar at the non-main node of the working layer should be set equal spacing according to the need of supporting scaffolding, and the maximum spacing should not be greater than 1/2 of the longitudinal distance. 

    作业层脚手板应铺满、铺稳,离开墙面120~150mm;狭长型脚手板,如冲压钢脚手板、木脚手板、竹串片脚手板等,应设置在三根横向水平杆上。当脚手板长度小于2m时,可采用两根横向水平杆支承,但应将脚手板两端与其可靠固定,严防倾翻。宽型的竹笆脚手板应按其主竹筋垂直于纵向水平杆方向铺设,且采用对接平铺,四个角应用镀锌钢丝固定在纵向水平杆上。 The scaffolding of the working layer should be covered and paved steadily, 120-150 mm away from the wall; the long and narrow scaffolding, such as stamped steel scaffolding, wooden scaffolding and bamboo strand scaffolding, should be set on three horizontal poles. When the length of scaffold is less than 2 m, two horizontal horizontal poles can be used to support the scaffold, but the two ends of the scaffold should be fixed reliably with it to prevent tipping. Wide bamboo scaffolds should be laid perpendicular to the vertical horizontal pole according to the main bamboo bars, with butt flat paving and four corners fixed on the vertical horizontal pole by galvanized steel wire. 

    每根立杆底部应设置底座或垫板。脚手架必须设置纵、横向扫地杆。纵向扫地杆应采用直角扣件固定在距底座上皮不大于200mm处的立杆上。横向扫地杆亦应采用直角扣件固定在紧靠纵向扫地杆下方的立杆上。当立杆基础不在同一高度上时,必须将高处的纵向扫地杆向低处延长两跨与立杆固定,高低差不应大于lm。靠边坡上方的立杆轴线到边坡的距离不应小于500mm。 Base or backing plate should be installed at the bottom of each vertical pole. Scaffolds must be provided with vertical and horizontal sweeping rods. The longitudinal sweeping rod should be fixed on a vertical pole with a thickness less than 200mm from the base. The horizontal sweeping rod should also be fixed on the vertical pole below the longitudinal sweeping rod with a right angle fastener. When the foundation of the upright pole is not at the same height, the vertical sweeping pole at the upper level must be extended two spans to the lower level and fixed with the upright pole. The height difference should not be greater than lm. The distance from the vertical axis above the slope to the slope should not be less than 500mm.
