The invention relates to the technical field of concrete devices, in particular to a concrete foundation bolt pre-burying and locating tool. The concrete foundation bolt pre-burying and locating toolcomprises cross arm assemblies, first connecting portions, second connecting portions and adjusting devices. The first connecting portions are connected with the cross arm assemblies and are used forfixing the cross arm assemblies. The second connecting portions are connected with the cross arm assemblies and foundation bolts and are used for connecting the foundation bolts with the cross arm assemblies. The adjusting devices are used for connecting the cross arm assemblies together. The concrete foundation bolt pre-burying and locating tool has the advantages that the foundation bolts are located rapidly, precision is high, and stability is high during pouring.
