Description
Technical field
The present invention relates to a kind of cantilever part decorative operation operating platform, more particularly to a kind of steel structural roof length is encorbelmented portion
Position decorative operation operating platform.
Background technology
It is the overall vision for pursuing facade in engineering construction engineering, building designers more and more adopt
Represent the stereovision of whole building thing with design as cantilevered structure, what the outward appearance that such as Chinese Pavilion layer stackup is chosen gave people
Feel to be even more grand air, but exactly this version, in structure construction stage and decoration construction stage all applying to engineering
Work industry brings great difficulty.
This structure encorbelmented, there is two kinds of versions, and a kind of cantilevered structure for concrete, another kind is steel beam column
Cantilevered structure.
If the cantilevered structure of concrete, in structure construction, the way for generally adopting for the externally picking tyoe girder steel on flooring,
Set up crosshead on section steel beam again to carry out the construction of last layer cantilevered structure；In decoration construction, also using this behaviour that encorbelments
Decorative operation is carried out as frame.Take this mode to carry out construction operation, need pre-buried shaped steel anchor ring in advance, wait next Rotating fields
When concrete strength reaches design requirement, section steel beam could be inserted in anchor ring, and flood crosshead is set up on section steel beam, this
Although sample can solve shop problem, it sets up and removes the long in time limit of needs, and the material lease expenses of crosshead is high, once and
Cantilever span is excessive, then safety problem cannot be protected at all.
If the cantilevered structure of steel beam column, in structure construction, the steel beam column at its cantilevered structure position can be in tower crane and shoe
Band to hang etc. and carry out under the auxiliary of heavy-duty lifting machine installation exercise and other steel beam column firm weldings.Using steel beam column as encorbelmenting
During structure, the cantilever span of steel structural roof is often most long, it is impossible to safe and reliable operating platform of encorbelmenting is set up on floor and is entered
Row decorative operation, to the long cantilever part decorative operation of steel structural roof huge difficulty is brought.In the market still without one kind
The operating platform for being specially adapted for the long cantilever part decorative operation of steel structural roof with maltilevel security security system.
