Abstract
The invention discloses a combined beam structure which comprises an upper flange and a lower flange, wherein steel beam web plates are vertically mounted on the upper flange and the lower flange and in positions close to the two ends; the two ends of the upper flange and the lower flange penetrate through the steel beam web plates; the steel beam web plates are respectively welded to the upper flange and the lower flange; steel beam lining plates are mounted on the inner side surfaces of the two steel beam web plates; the tops and the bottoms of the steel beam lining plates are respectively fixedly connected with the upper flange and the lower flange; guard boards are vertically mounted in the steel beam lining plates and welded to the steel beam lining plates; upper U-shaped steel is mounted on the lower surface of the upper flange; lower U-shaped steel is mounted on the upper surface of the lower flange; and the upper U-shaped steel and the lower U-shaped steel are arranged symmetrically and are respectively welded to the upper flange and the lower flange. The combined beam structure provided by the invention is convenient to connect and firm in self structure, has better support performance, is excellent in protective performance and uniform in stress, saves steel consumption and effectively improves bending bearing capacity and fire-resistant limit capacity of a component.
Description
Technical field
The present invention relates to a kind of building structure, particularly a kind of combined beam structure.
Background technology
The collar tie beam of general building adopts reinforced concrete structure mostly, and its major defect is: one, building operations program is complicated, and the amount of labour is large, long in time limit, and produces a large amount of building waste; Two, do not have reliable drawknot between collar tie beam and floor, antidetonation, waterproof and heat insulation effect are difficult to reach desirable state; Three, need a large amount of templates in building operations, and installation and dismounting all very bother, and considerably increase workload, extend the construction period.Simultaneously general collar tie beam design is also unstable on switching performance, phenomenons such as subsiding may be there is, cause the generation of safe condition, and general girder construction more cannot reach good support effect, easily there is skew and buckling phenomenon, can not better play the effect of bracing reinforcement, so, need to make good improvement to it, can better support effect be reached, play protective action.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the problems referred to above, and provide a kind of easy to connect, self structure is firm, can better play support performance, the extraordinary combined beam structure of barrier propterty.
To achieve these goals, the technical solution used in the present invention is such: combined beam structure of the present invention, comprise top flange and bottom flange, top flange and bottom flange are vertically provided with steel beam web plate near two ends place, top flange and two ends, bottom flange are all arranged through steel beam web plate, steel beam web plate welds respectively with between top flange and bottom flange, two steel beam web plate medial surfaces are provided with girder steel interior lining panel, girder steel interior lining panel top and bottom are fixedly connected with respectively with between top flange and bottom flange, vertically backplate is installed in girder steel interior lining panel, backplate is welded on girder steel interior lining panel, top flange soffit is provided with U-shaped steel, bottom flange upper surface is provided with lower U-shaped steel, be symmetrical arranged between upper U-shaped steel and lower U-shaped steel, upper U-shaped steel and lower U-shaped steel weld respectively with between top flange and bottom flange.
Further, as a kind of concrete form of structure, between steel beam web plate of the present invention and top flange and bottom flange, be connected to installation screw rod, screw rod be installed and arrange through top flange and bottom flange.
Further, as a kind of concrete form of structure, backplate of the present invention is steel bar girder carrier plate structure.
Further, as a kind of concrete form of structure, U-shaped steel of the present invention and lower U-shaped steel are provided with shear connector respectively and between top flange and bottom flange.
Further, as a kind of concrete form of structure, between steel beam web plate of the present invention and girder steel interior lining panel, adjustable members is installed.
Further, as a kind of concrete form of structure, steel work bar between backplate of the present invention and girder steel interior lining panel, is interspersed with.
Compared with prior art, the invention has the advantages that: this combined beam structure is easy to connect, self structure is firm, can better play support performance, barrier propterty is very good, uniform force, save steel using amount, effectively improve anti-bending bearing capacity and improve the fire endurance ability of component.
