Description

Technical Field

[0002] Bolts are a type of fastener consisting of a head and a screw (a cylinder with external threads). They need to be used in conjunction with nuts to fasten two parts with through holes. They are anchoring components that anchor the connected parts to the hardened concrete substrate. In the process of producing large equipment, it is often necessary to reserve bolt holes on its surface for subsequent installation of screws. When reserving bolt holes, bolt hole models are used to implement the reserved hole operation.

[0003] Prior art includes a utility model with publication number CN201695677U, which discloses a model of reserved bolt holes for large equipment foundations.

[0004] The inventors have discovered in their daily work that in the process of using the reserved bolt hole model, the existing reserved bolt hole model structure, such as the above-mentioned one, is relatively simple, and it mainly relies on the structure of the hole body to perform the reservation function.

Since the model structure only relies on itself for support, the model structure will be deformed when the equipment squeezes the model structure, thereby causing the shape of the reserved bolt hole to change, resulting in a decrease in the bolt hole forming accuracy.
