Q:Will the concrete cloth machine and the tower crane is different, long quite like Please explain the structure of the application, 3Q

Oh, that love what the lay it? Concrete is the end of the concrete pumping equipment, the role is to pump the concrete through the pipeline to be poured to pour (to say that the "building" is the word is also lay it, huh, huh) components within the template

Q:Will the equipment based on the beam column and other structures, can not be poured once completed, should be set up civil construction or fixed?

So do the project budget review work, will help improve the design level and investment efficiency

Q:Construction technology measures fee is directly into the sub - project costs

Construction technology measures fee is not directly into the sub-project costs, because the construction technology measures fees are measures fees rather than sub-project costs, measures fees, refers to the completion of the project construction, occurred in the construction and construction The cost of non-engineering entity projects during the process consists of construction technical measures and construction organization measures

Q:A man of mass 74.4 kg stands on a scaffold supported by a vertical rope at each end. The scaffold has a mass of 21.9 kg and is 3.9 m long. Suppose the man stands to the right from the middle of the scaffold that is a distance one sixth of the length of the scaffold. What is the tension in the right rope? b) What is the tension in the left rope? thanks in advance.

Left rope = T1 Right rope = T2 1/6 of 3.9 m = 0.65 m 3.9/2= 1.95 1.95 - 0.65 = 1.3 m from right rope. Take g = 10m/s^2 T1 = ((219 x 3.9)/2) + (744 x 1.3) = 1394.25 1394.25 = 3.9 x T1 1394.25/3.9 = T1 = 357.5 N (answer for left rope) T2 = ((219 x 3.9)/2) + (744 x (3.9 -1.3)) = 2361.45 2361.45 = 3.9 x T2 2361.45/3.9 = T2 = 605.5 N (answer for right rope)

Q:I'm still at school and if I got my scaffolding done at the start of the summer holidays it would have 6 weeks to heal, I would have to take it out once a week for 2 hours, would I experience any issues?

They take 9-12 months to heal and an unhealed piercing should never be removed. Yes, you would experience issues. It would likely close or shrink in size or if it somehow didn't then you could easily cause infection, irritation, prolonged healing, hypertrophic scarring...nothing you should be willing to risk. 6 weeks is far from being long enough.

Q:Is it necessary to use a mat on the floor? Is that norm prescribed?

Scaffolding erection specification staff up and down and transport materials When lifting the weight with the lifting device, it is not permissible to connect the lifting device and the scaffolding structure set up scaffolding work leaders should take the scaffolding to pass the test and issued a written proof of the use of the prospective use The person in charge of the maintenance work should check the status of the scaffolding and scaffold used daily, and if necessary, refurbish immediately is strictly prohibited with hand barrels, wooden boxes, bricks and other building materials take temporary plate to replace the regular scaffolding scaffolding on the prohibition of random wire Must be installed temporary lighting lines, wood bamboo scaffolding should be added insulators, metal pipe scaffolding should be another wooden cross the installation of metal pipe scaffolding, prohibit the use of bending, flattened or cracked pipe, the successive parts of each tube to be intact, to prevent dumping or moving metal pipe scaffolding of the pole, must be vertically placed on the plate, in the placement of the floor before the ground to consolidate, leveling The pole should be fitted with a pillar, which is made of a pillar base and a pipe welded to the floor metal pipe scaffolding joints, the application of special hinges overlap each other, this hinge for right angles, but also for acute and obtuse (for bracing, etc) The hinge bolts connecting the various components must be tightened scaffold board must be fixed in the metal pipe scaffold on the beam when moving scaffolding, the scaffolding of all staff must be down, above the work of the scaffolding prohibited to move.

Q:Such as the title, raw materials and structural parts What is the difference, how to divide?

There are columns: pipe pile, frame column, independent column, structural column, Cylindrical, L-shaped columns; brick columns, concrete columns, wooden columns Beam: frame beam, connecting beam, over beam, ring beam, cantilever beam, curved beam; steel beam, wooden beam, concrete beam Plate: cast-in-place board, prefabricated flat plate, prefabricated hollow plate; reinforced concrete plate, wood board Wall: brick wall, concrete wall, roof daughter wall, light partition Doors: solid wood doors, plywood doors, steel doors Windows: steel windows, wooden windows, aluminum windows, steel windows Building accessories are construction and construction components other than building blocks, such as scaffolding, pipe thread regulators for construction, construction bars, triangular construction supports, and steel joints

Q:the reading on the left scale is 400n what should the reading on the right scale be?

Total weight is 300+250+300 = 850 weight on other scale is 850–400 = 450 newtons

Q:How to do a good job in typhoon prevention work in rural areas?

Listen to weather forecasts, reinforce Dapeng and other infrastructure, to prevent lightning, to quickly cut off all kinds of electrical power

Q:What would you like to ask?At what height do scaffolds have to be engineered?

At all heights...they are engineered as a system.
