Q: What are the advantages and disadvantages of the fastener type steel pipe scaffold and bowl buckle steel tube scaffold: (4) the bearing capacity is large: the vertical rod connection is a coaxial core socket, and the cross bar is connected with the vertical rod by a bowl buckle joint. And the axial line of each member is placed at one point, and the node is in the plane of the frame. (the entire frame bearing capacity, about the same clear fastener type steel tube scaffold condition is improved by more than 15%,)

Q: i already found the force in rope 2 but im not getting the force in rope 1.: The tension in the two vertical ropes must sum to 700N in order to balance the window washer. EDIT. In order to find the answer for each rope, I need to know how long the scaffold is and where the window washer is standing. EDIT. Taking moments about the end nearest to window washer. T1*3.044 = 298.6*1.522 + 700*1.51 ----> T1 = 496.54 N (2. d. p.) Taking moments about the other end. T2*3.044 = 298.6*1.522 + 700*1.534 ----> T2 = 502.06 N (2. d. p.) T1 + T2 = 496.54 + 502.06 = 998.6 = 700 + 298.6 as required.

Q: If you have two workers say standing on a scaffolding, their are downward forces from the weight of the workers along with the weight of the scaffold, and upward forces from tension suspending the scaffolding in place. The opposite forces add to zero and thus the scaffolding remains at rest.My question has to do with what would occur if more/less workers were on the scaffolding. It appears to me that the scaffolding would always remain at rest. Would there always be a ΣF=0 regardless of the amount of workers? As the decreases in weight from removing a worker would also cause the tension force to be weaker? And vice versa if there were more workers?I: You are correct so long as the scaffolding is not allowed to move. I.e. the cables suspending it are locked and not unwinding from their spools as more workers get on. More weight added would necessarily increase the tension in this type of case. However, if, when another worker got on and the tension could not increase for what ever reason, a downward acceleration would take place that is proportional to the worker's weight. Hope that clears things up.

Q: Sweeping rod, large cross bar, small cross bar, scissors brace, vertical pole, right angle fastener, rotating fastener, butt joint fastener, even wall piece! If there is a cantilever frame, the main beam, steel wire rope, such as pull down support: Steel tubular scaffold. As to the steel pipe, and combined with other type of steel pieces composed of scaffolding, such as the channel has a base in the backwater or scaffolding, connecting steel scaffolding and so on.

Q: What are the requirements for the sampling inspection of scaffolding?: Inspection and acceptance of cantilever scaffold1 after the erection of the cantilever support, the scaffold is erected;2 before loading on the work layer;3 after each set of 10m height;4 after reaching the design height;5 in the case of more than six winds and heavy rain;6 use more than a month.Cantilever scaffold inspection document1 special construction plan and design documents;2 safety technical disclosure;3 the provisions of appendix D, table D.1.

Q: How to maintain the scaffold after use: Tool type scaffolding (such as door frame, bridge frame, hanging basket, receiving table) in the removal of the need to stop the maintenance and timely maintenance, and supporting storage.

Q: Bracket cast-in-place beam bracket must use bowl buckle scaffold, can not use fastener type scaffolding, there is no mandatory requirements, or specification file requirements!: 5.2.5, the calculation of the column, a clear calculation of the type of stud.6.2.4, clear the structure of fastener type column.Local documents, it is not possible to regulate, do not allow the use of fastener type scaffolding. But the top of the column, to use the provisions of backwater, specification.

Q: why scaffold need for inspected within the preceding 7 days and after adverse weather condition?: It is a work safety issue. Past experience has shown that scaffolding sometimes gets modified by unqualified people (or weather) resulting in injury or death.

Q: Bowl buckle type steel pipe scaffolding should set up a few people: What are the form and structure of bowl buckle scaffold?Composition formA bowl type steel tube scaffold is a multifunctional scaffold in our country with reference to foreign experience developed, its member nodes connected with bowl, because the bowl is fixed on the steel pipe, all components of the axial connection, good mechanical properties, which is reliable, consisting of the scaffold with good integrity, there is no fastener lost problem.

Q: I really want a scaffold piercing and I can pay for it, I get good grades, I do all the chores I have to do, I spoke to them calmly and everything. Yet they still won't let me. My dad said that I will be grounded forever and everything but last time I got grounded, I went to a party the next day so what should I do?: im talking from experience-scaffold piercings are VERY painful, and take a long time to heal. so there wouldnt be any way you could take it out to hide it for a good few months! it really isnt a great piercing to get unless you can openly look after it properly. anyway you shouldnt disregard what your parents say...i know thats what you want to do!lol really though, its very painfull!
