classification

Anchor bolts can be divided into fixed anchor bolts, movable anchor bolts, expanded anchor bolts and stuck ground anchor bolts.According to their different shapes, they can be divided into L type embedded bolts, 9 type embedded bolts, U type embedded bolts, welding embedded bolts and bottom plate embedded bolts.

 

installation method

1. One-time embedding method: when pouring concrete, embed the anchor bolts.When the tower is overturning, the anchor bolt should be embedded in one time.

2. Hole reservation method: the equipment is in place, the holes are cleaned, the anchor bolts are put into the holes, and after positioning and aligning the equipment, the non-shrinkage fine stone concrete, one level higher than the original foundation, is used for watering and tamping.The distance from the center of the anchor bolt to the edge of the foundation shall not be less than 2d(d is the diameter of the anchor bolt), and shall not be less than 15mm(d≤20 shall not be less than 10mm), nor less than half of the width of the anchor plate plus 50mm. When the above requirements cannot be met, appropriate measures shall be taken to strengthen it.The diameter of anchor bolts for structure should not be less than 20mm.When subjected to seismic action, double nuts should be used for fixation or other effective measures to prevent loosening, but the anchorage length of anchor bolts should be increased by 5d compared with that of non-seismic action.

Anchor bolt installation planning anchor bolt looseness in the foundation treatment in close to tighten the anchor bolts, is likely to bolt, pull bolts at this time should be adjusted to the original position, and shovel out the basis of enough positions around the bolt, then the welding vertical and horizontal two u-shaped steel bolt, the last water will be a pit clean and grouting, the intensity of concrete in the design and then tighten the anchor bolt live anchor bolt deviation processing deviation method, roughly the same as the death of the bolt method, only anchor bolt can be drawn.If the bolt is too long, you can cut off a section of thread on the machine;If the bolt is too short, it can be elongated by hot forging.If the position does not match, correct by bending method.

Application: applicable to all kinds of equipment fixing, embedded parts of steel structure foundation, street lamps, traffic signs, pump, boiler installation, embedded fixed heavy equipment, etc.
