Description
Technical field
The utility model relates to the beam-string structure systems in a kind of reinforcing of large span rigid frame.The utility model further relates to above-mentioned
The construction method of beam-string structure system in the reinforcing of large span rigid frame.
Background technique
Along with reform and opening-up, since the eighties in last century, China has built a large amount of industrial premises.With work in recent years
The development of industry modernization, large quantities of Portal Rigid Frame Factory Structures that early period builds generally face using changes of function and lead to structure
The problem of load increases, this makes original structural-load-carrying capacity have been unable to meet current specifications requirement, is badly in need of reinforcing.
Conventional portal-rigid frames reinforcing generally is passive type reinforcing, generallys use using increasing section, adds rest etc.
Method is reinforced, and newly-increased component has secondary loading, not can guarantee with original structure cooperative bearing, only when load-bearing reaches
When to certain value, newly-increased component just works, and causing original structure component with newly-increased component, there are stress differences.And newly-increased structure
Part and the direct welding workload of former component are big, not can guarantee construction quality, in the welding process in fusion pair after the melting of steel
Original structure intensity also has considerable damage.And the reinforcing mode of traditional increasing section influences very existing building clear height
Greatly, the use function of existing building is seriously affected；And traditional reinforcing mode is typically necessary setting temporary support, occupies factory
The production space in room, so that workshop normal operation can not carry out.
Utility model content
The technical problem to be solved by the utility model is to provide one kind can significantly be promoted girder steel bearing capacity it is big across
Spend the beam-string structure system in rigid frame reinforcing.Technical problem to be solved in the utility model further include provide it is a kind of it is above-mentioned greatly across
Spend the construction method of the beam-string structure system in rigid frame reinforcing.
For this purpose, the beam-string structure system in large span rigid frame reinforcing provided by the utility model：It is arranged on its mill building frame
There is bracket fixing piece, tensioning has lower edge between two bracket fixing pieces, and support rod is supported between lower edge and girder steel.
In the above-mentioned technical solutions, the bracket fixing piece is fixed on the side of girder steel, and bracket fixing piece is connect with side column
There is brace, brace one end and the hinged other end of bracket fixing piece and side column are hinged.
The technical effect of the utility model：
1, bracket fixing piece tensioning lower edge on workshop original frame is utilized in the utility model, and is supported on using support rod
Between girder steel and lower edge, when girder steel local pressure is excessive, then can pass sequentially through support rod --- lower edge --- support rod
The excessive pressure that girder steel is locally subject to by mode evenly spreads to each position of each girder steel, to promote the integrated carrying energy of girder steel
Power.
2, the bracket fixing piece of two sides is hinged using brace and side column, and the partial pressure for being further subject to girder steel is distributed to
It on side column, while pre-tightens bracket fixing piece in lower edge between the power of tensioning and the hinged pulling force of brace and reaching balance, favorably
In promotion overall stability.
3, active reinforcing mode, tensioned prestressing bar are belonged to using the external prestressing strengthening technology of beam-string structure system
Afterwards, presstressed reinforcing steel shifts to an earlier date stress, works asynchronously with original structure component, and stress difference is not present in the two；
4, due to presstressed reinforcing steel scale of construction very little itself, presstressed reinforcing steel the space occupied is seldom after reinforcing, can adapt to girder steel
Lower section small space；
5, the lower edge arrangement that prestress wire is constituted is flexible, can be according to equipment installation flexible arrangement steel strand wires
Position, and the workload very little for needing to weld in work progress, it is guaranteed to construction quality；
6, it is reinforced using external prestressing technique, to the current Influence to operation very little of original building, can be used not limiting
Under the conditions of reinforced.
