Q:Scaffolding steel pipe support spacing
Open type double row steel pipe scaffolding pole spacing 1.05, 1.30, 1.55M.Open type single row steel pipe scaffolding pole spacing 1.20, 1.40M.
Q:How to distinguish between the columns of single and double steel support
2, the column support column bracing is to ensure the construction of the overall stability of the structure, improve the lateral stiffness and the transfer of longitudinal horizontal force between the adjacent two columns of the connecting rod.
Q:In the case of the project under the circumstances of steel support
Now almost all steel support. Large steel support load
Q:Welding steel support electrode needs to be tested
Electrode type electrode diameter /mm drop height /m electrode electrode skin rupture length/mm carbon steel welding rod, low alloy steel electrode, stainless steel electrode< 41 < 30 > 40.5 < 40Cast iron electrode< 40.7 < 304; 50.5 = 60.3Welding electrode is less than 4 D/d = 1.7 D/d > 1.73010.7 = 4Zero point fiveZero point threeNote: D is the electrode diameter, mm; D core diameter, mm.(3) test for moisture resistance of electrode coatingThe electrode immersed in 15 to 20 degrees Celsius in the water, 4H (cast iron electrode 0.5h) after the observation, the skin should not be opened, cracking or peeling phenomenon.4) test welding length, the diameter of the core wireThe electrode length and core diameter, clamping end length, the relevant provisions should be in accordance with GB/T 5117-95 and GB/T 5118-95 respectively, GB/T 983-95, GB 984-85 and GB 10044-88 standard.
Q:Is the calculation of the axial force of concrete support and steel support
Axial force calculation is the same. But there are differences in the specific design calculations.
Q:How to speed up the construction speed of steel support in the excavation area
The axial force of the diagonal brace is 1/sin times of the same span. The angle between the axis and the axis of the crown beam
Q:Why subway steel support axial force value
Calculation of axial force of steel support in deep foundation pit:The first plus zero, the calculation of a cable tension, the anchor cable tension is able to ensure the stability of the foundation pit resistance, and then on the basis of the times on the basis of the standard 70~95%.Preload is generally not more than 450kN, because of the use of pile anchor structure is mostly sand, silt, or clay, anti pulling force of this stratum and anchor is limited, 450kN means that the prestressing design tension reaches 450/0.95~450/0.7, which is basically the ultimate anchor in this ordinary formation, if not met to consider the encryption of anchor spacing.
Q:What are the differences and similarities between the support of wood, steel, and steel?
Wood support is used as a supporting component of wood, usually used for relatively small force and load structure; easy to draw materials, simple and convenient construction, low cost, should be used as a support.
Q:Why should the deep foundation pit support axial force monitoring?
There is a problem with our numerical axial force meter measured are small, usually the first force only after the pre 30%~70% value, sometimes even very small, and they force to support unit said, as a result of retaining wall (pile) large deformation,
Q:Steel support is used in deep foundation pit
Large volume concrete (floor) set after pouring belt, according to the design drawings.CFG pile is a method of cement, fly ash and gravel to reinforce the foundation, and the bearing capacity of the composite foundation is not very high.
