Description

Technical Field

[0001] The utility model relates to the technical field of embedded molds, in particular to a reusable embedded mold for small-sized embedded holes. Background Art

[0002] Embedded parts are pre-installed and buried in concealed projects. They are components installed when the structure is poured. For example, in building construction, embedded parts are set in the wall before pouring concrete, and then poured to fix the embedded parts in the wall. Finally, external engineering equipment is fixed to the embedded parts with bolts, thereby realizing the installation and fixation of the foundation of external engineering equipment. In existing building construction, bolt holes are usually reserved. In view of the situation where there are many and small holes for bolts and other holes in the equipment foundation of factories and other projects, the traditional method is to use plywood to make wooden boxes. In the past, bamboo plywood was used for small-sized reserved holes and was made on-site by carpenters, but the on-site efficiency was low, the structural dimensions were not accurate, and they were all disposable and could not be reused.
