Description
Technical field
The invention belongs to box type transformer substation base fields, become basis and its scene more particularly, to a kind of assembled case
Construction method.
Background technique
Currently, building overwhelming majority when box type transformer substation base all uses cast-type construction method, the case of cast-type becomes base
Plinth haves the shortcomings that following:
1) long in time limit, cast-type case becomes basis and needs live assembling reinforcement, live formwork, poured in place concrete, later period
Demoulding etc., it is long in time limit；
2) costly, from ground excavation, assembling reinforcement, production mold, concreting, concrete curing, form removable
It just needs to spend more expense；
3) effect on environment is big, and case becomes basis and often builds in city, and the excavation of foundation soil unavoidably will affect city
Environment influences city image, and the construction period that cast-type case becomes basis generally requires one month or more time, for city
Environment is affected, and influences normally to go on a journey.
Invention at present for the box basis of assembled is seldom, and existing assembled case change basic constructional design is unreasonable,
Structure force path is inappropriate, and globality and stability are all poor, and pours after assembled case becomes in the assembly of basis and used
Concrete, causing assembled case to become basis cannot reuse, is long in time limit, is costly etc., these unfavorable factors all limit
Assembled case becomes the application and popularization on basis.
Summary of the invention
Aiming at the above defects or improvement requirements of the prior art, the present invention provides a kind of assembled casees to become basis and scene
Construction method passes through structure and the arrangement side to such as six kinds of key component basic bottom plates, upright post base, column and junction steel plate
The design of formula, obtaining a kind of structurally reasonable, force path, clearly assembled case becomes basis, has short time limit, at low cost, just
In manual assembly, advantage reusable, environmental perturbation is small.
To achieve the above object, according to one aspect of the present invention, a kind of assembled case change basis is provided, including under
The supreme bottom plate set gradually, upright post base, column and junction steel plate, in which:
Bottom plate is poured by armored concrete, is embedded with the bolt for connecting upright post base, the side of bottom plate thereon
