Is it not possible to use embedded bolts in concrete frames? How can one embed it accurately?
Thread Content
I need help. I’m facing the following issue: it’s necessary to install bolts accurately in the foundation for the equipment, which is placed on a concrete frame. Is there any significant difficulty involved in the civil engineering work?
The precision requirements are too high. If I have to do this, I will create a framework for all the foundation anchor bolts, then set up forms and add reinforcement, followed by pouring concrete. It will be necessary to make fine adjustments to each bolt to ensure that all relative dimensions are correct. Temporary adjustment fixtures can be used for this purpose; once the concrete has reached 50% of its strength, these temporary fixtures can be removed. Once the required strength is achieved, the equipment can be installed in place
So, in general, is it about embedding plates within the framework? Would that make it much more difficult compared to embedding them in the ground?
Thank you all. As *Yi, when setting requirements for the civil engineering team, due to the issue of sliding saddles, I insisted on having anchor bolts and embedded plates precisely installed in the concrete frame. The civil engineering team told me that this would be extremely difficult to carry out and asked me to change my requirements, but the demands set by *Yi must be met. That’s why I’m asking everyone for their opinions.
The second floor explained it in great detail and clearly.
Reply to 10# 41303: During construction, it is necessary to use custom-made steel molds to accurately position the bolts, in order to prevent any displacement during the concrete pouring process. It fails to prevent the equipment from not being able to be installed once the bolts shift. It is possible to request that the bolt holes in the equipment base be designed as slotted holes.
