Anchor bolts are widely used in various building infrastructure equipment, such as concrete equipment foundations, steel structure independent concrete foundations, etc. Their main connection is a strip steel structure device, and the installer needs to master the embedded ground according to the construction requirements of the steel structure Control of anchor bolt construction.Today, the editor will briefly introduce the construction technology of anchor bolts.
XNUMX. The construction process of anchor bolts
Generally speaking, the construction process of anchor bolts is generally divided into five parts, that is, processing order→measurement and positioning→support bracket→placement of anchor bolts and temporary fixation→retest and fixation.
XNUMX. Construction method of embedded anchor bolts
1. Submit processing order
Before the construction of the project, the installer should design the drawings according to the actual situation, and design the specifications, materials and quantities of the anchor bolts according to the requirements.When filling in the form, indicate the order and time of appearance of the semi-finished product, and then submit it to the superior department.The technical person in charge of the engineering construction unit will determine the processing and acceptance of the bolts according to the requirements of the semi-finished product commission and certificate.After all the information is confirmed, the anchor bolts are transported to the processing plant for processing.
2. Measurement and positioning
The surveying personnel will measure the anchor bolts according to the positioning list, and then use the laser rangefinder and theodolite to measure the baseline net, and draw the center control line and the elevation control line of the column base, and then check and re-test them to confirm that they are correct. be usable.In addition, the specific location can be determined according to the center and elevation of the anchor bolt.
3. Support bracket
In the early stage of bolt installation, attention should be paid to the fixing of the brackets. The anchor bolts should be completely separated from the formwork fixing frame, rib fixing frame and other frames to form their own system, so that it has a certain degree of stability and toughness.
4. Place anchor bolts and temporarily fix them
After the fixed frame is supported, the center is fixed according to the positioning line, and then the elevation is adjusted and temporarily reinforced according to the requirements of the plan.
5. Retest and fix
After fixing the anchor bolts, it is necessary to place the anchor bolts and adjust the horizontal and vertical axes and elevation points of the anchor bolts with various instruments.After the inspection by the technical management personnel, the relevant personnel should weld and fix the lower part of the anchor bolts that meet the standards and requirements, and then strengthen the bolt fixing frame along the horizontal and vertical axis.
