Q:How to calculate the vertical force of scaffolding
The calculation of steel tubular scaffold with reference to "construction safety code for steel tubular scaffold with couplers" (JGJ130-2001). Need to calculate the following eight aspects:
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
Mobile scaffolding is the main frame, cross frame, cross diagonal brace, foot board, adjustable base and other components. The cross rod is also called the diagonal pull rod, and is a cross connecting rod which is vertically connected with the two door frames. The part of both ends of the rod part is punched with a pin hole, and the locking pin on the vertical rod of the door and the frame is locked when assembling.
Q:Is it easier to build a disc scaffolding system than a bowl buckle scaffold?
Disc scaffolding systemIs a new type of scaffolding, the product was introduced in Europe in the last century in 80s, is the upgrading of products after the bowl buckle scaffold. Also called chrysanthemum disc scaffolding, scaffold system, disc scaffolding system, buckle disc scaffolding, layher frame (layer frame, Lei Ya frame, because the basic principle of the scaffold is by the German LAYHER (Lei Ya)'s invention, the industry has been called the "thunder sub frame"
Q:what are the scaffolding building on I-44 between milemarker 282 and 283 east bound on the north side of the h
Are you talking about where the trains are? The cylander shaped buildings? They are oil/fuel tanks... they have a big balloon like thing with a weight on top that as it fills will fill out inside the scaffolding. I have not seen them filled in years though.
Q:What is the rental price of the mobile scaffolding and accessories now? How to rent a law?
Mobile scaffolding in general are on the basis of rent by the day
Q:Specific specification for erection of civil scaffold
Calculation basisScaffolding input: for the template support part of the steel pipe material in accordance with the 1.5 layer of the amount of consideration: the amount of external scaffolding steel pipe in accordance with the full closed scaffolding consideration; safety net in accordance with the external scaffolding full consideration.
Q:Specification for construction steel pipe scaffolding and construction safety rules?
Construction preparation1, materialThe steel pipe diameter is 48 or 51mm, wall thickness is 3 ~ 3 5mm or hot-rolled seamless pipe joints, used as the main column, a large bar, a small bar, inclined support.The connecting member: rotary buckle, square buckle, buckle, docking barge core.The base made of phi 40 steel tubes and 4 ~ 5mm steel, used for main column stepping. The floor area of the base should not be less than 200C.
Q:What are the requirements for the sampling inspection of scaffolding?
1 the sampling proportion of various structural parts shall not be less than 5% and not less than 20 pieces, and the quality shall comply with the relevant standards and regulations. Not meet the quality requirements of the structural parts shall not be used.2 wall thickness of steel pipe should be in line with the provisions of the special construction program, and shall not be less than 2.8mm, the wall thickness of less than 2.8mm of the steel pipe shall not be used;3 is strictly prohibited the use of cracks, deformation of the fastener, the bolt appears to be replaced silk;4 foot hand frame accessories must be used before the anti-corrosion treatment.
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:In the calculation of the bearing capacity of the scaffold, what is the axial force produced by the "N g2k" - the standard value of the component?
Hello friends, NG2K said the weight of the standard parts of the standard value of the axial forceNG2K (kN) formula: NG2K = NG2+NG3+NG4 = 3.094 kN; NG2 and NG3, respectively, NG4(2) scaffolding deadweight standard value (kN/m2); the bamboo scaffold board, the standard value of 0.30NG2= 0.300 x 7 x 1.500 x (1.050+0.3) /2 = kN = 2.126;
