Ground Screw/Ground Anchor/Bolts/Q235/massachusetts solar installers

Mechanical  components on the basis of the installation of concrete, the bolt was  J-shaped, L-shaped end of the use of concrete buried in the concrete.
The  tensile strength of the anchor bolts is the tensile capacity of the  steel itself, and the size is equal to the cross-sectional area  multiplied by the allowable stress value (Q235B: 140MPa, 16Mn or Q345:  170MPA) is the design of the tensile capacity.
The anchor bolts are generally made of Q235 steel. Rebar (Q345) strength, do nuts do not have the round button easy. For the light round foot bolts, the depth is generally 25 times the diameter of it, and then do a 120mm long 90 degrees hook. If  the bolt diameter is very large (such as 45mm) buried depth is too  deep, you can weld the end of the bolt, that is, to do a big head on it  (but also have some requirements). Buried and hooks are to  ensure that the friction between the bolt and the foundation, and will  not pull the bolt out of the destruction.

Alias  anchor anchor anchor bolts, welded anchor bolts, anchor claw-type  anchor bolts, ribs-type anchor bolts, to the foot bolt, to feet screws,  foot wire and so on. Specifically for buried in the concrete foundation, for a variety of fixed machinery, equipment, base. 7 word anchor bolts for the anchor bolt in a more commonly used one. The  general use of Q235 steel production, the use of high strength Q345B or  16Mn material processing, but also useful 40Cr material processing 8.8  strength of the product, occasionally useful secondary or three rebar  processing. Anchor bolts are wool, thick bar, thin rod of different forms of points. Wool  or raw material steel without restructuring, with round steel or wire  directly from the processing; thick rod or called A type, thin rod or  called B type, are converted into steel from the corresponding  requirements of the rod after processing from. The welded anchor bolts are made of single-headed bolts after they are welded. Its anti-drawing ability. According to the use of different conditions, respectively, can reach 3.6, 4.8, 6.8, 8.8 and other levels. 3.6 grade 7 word anchor bolts tensile capacity for the tensile strength of steel itself. Q345B or 16Mn raw materials directly to the anchor bolts of its tensile strength of up to 5.8 of the tensile strength. 4.8, grade 5.8, 6.8 and 8.8 of the tensile strength of GB / T3098.1 for the provisions of the mechanical properties.
