Mounting base

摘要

A mounting base is formed from a metal foundation, height adjustment bolts for adjusting the height dimension of the foundation, support bolts inserted into support bolt insertion holes, a metal cover installed on the foundation, and mortar filling the space between the foundation and the upper surface of a concrete slab. In the base, the first fixed ends of the bolts are inserted into insertion holes formed in a metal plate and are fixed to the metal plate with nuts, and the second fixed ends of the bolts are fixed to a steel beam with nuts. The portion of the first fixed ends of the bolts which extends between the metal plate and the top surface of the concrete floor is integrated with the mortar filling the space, and the metal cover covers the opening at the top of a metal tube of the foundation.

主权项

1. A mounting base that is installed at a predetermined position of a steel structure having a steel skeleton formed from a steel column and a steel beam, and a concrete floor provided on said steel skeleton,
said mounting base comprising a plurality of support bolts that are inserted into bolt hole openings in said steel beam and said concrete floor and have first fixed ends that upwardly extend by passing through said concrete floor and second fixed ends that downwardly extend by passing through said steel beam; a foundation that is upwardly spaced from said concrete floor at a predetermined interval; a cover that is installed on said foundation; a molding material that is provided between an outer circumferential edge of said foundation and said concrete floor that blocks a gap between the concrete floor and the outer circumferential edge of the foundation; and a cement cured object filling a space surrounded by said concrete floor, said foundation and said molding material, wherein said foundation has a bottom plate facing said concrete floor and a hollow tubing material that upwardly extends from said bottom plate, wherein first fixed ends of the support bolts are inserted into the bolt hole openings of said bottom plate and are fixed to the bottom plate with a fastening means, and second fixed ends of the support bolts are fixed to said steel beam with another fastening means, and a portion of the first fixed ends of the support bolts that extends between said concrete floor and said bottom plate is integrated with the cement cured object that fills said space, and said cover blocks an opening at a top of said tubing material, wherein the opening at the top of said tubing material is blocked by said cover just after filling the cement cured object into said space and prior to completion of a curing period of the cement cured object, the curing period of the cement cured object starts after the opening at the top of said tubing material is blocked by said cover, and a portion of the first fixed ends of said support bolts that extends between said concrete floor and said bottom plate is integrated with said cement cured object after completion of said curing period.
