The factory building individual layer mixes bent structure
Technical field:
The utility model relates to a kind of factory building, particularly the factory building bent structure.
Background technology:
Traditional steel concrete single storey industry workshop (load-carrying members system is made up of prefabricated reinforced concrete post, concrete roof truss, large roof slab), advantages such as though it is low to have cost, integral rigidity is better, and lateral deformation stiffness is big, but shortcomings such as it is slow to have speed of application simultaneously again, and profile is not attractive in appearance; Although steel building is because its quick construction, the bodily form is light and handy, good looking appearance, be applied to building structure in recent years increasingly extensively, particularly be applied to more in the factory building structure (load-carrying members system is made up of steel column, girder steel, profiled sheet), but it is poor that steel-structure factory building has integral rigidity again, the shortcoming that anti-sidesway ability is weak.Build for the large tonnage crane single storey industry workshop, can produce very big horizontal and vertical equity load to factory building during the crane operation, factory building vertical equity load can support and is delivered on the basis by intercolumniation is set, and factory building transverse horizontal load can only have enough horizontal lateral deformation stiffnesses to transmit by factory building columns, moreover, the horizontal movement value of factory building columns at crane runway absolute altitude place must satisfy the limit value of standard defined, exercise with the safety that guarantees crane, unlikely card rail, and in the factory building columns design of large tonnage crane, the horizontal movement limit value (being the rigidity control of post) that satisfies post becomes the major control factor of column section design.Steel are compared with concrete, has very high intensity and good ductility, steel column is generally formed by thin steel plate assembly welding, compare with prefabricated reinforced concrete post, the bearing capacity of steel column is very high, but lateral deformation stiffness is very poor, thereby the high advantage of steel strength is not brought into play well, want for the displacement that satisfies the rigidity of structure, have only the cross section of strengthening steel column, caused the waste of investment.On the contrary, prefabricated reinforced concrete column rigidity is big, and the reinforcing bar of configuration is also few in the post, and under the condition of same stiffness, the cost of prefabricated reinforced concrete column is more much smaller than steel column.
The utility model content:
Problem to be solved in the utility model is: provide a kind of and can satisfy quick construction, the bodily form is light and handy, good looking appearance, the horizontal force that is produced in the time of satisfying the operation of opposing large tonnage crane again, and the factory building individual layer that investment cost is low mixes bent structure, to overcome prior art problems.
The utility model is to constitute like this: it comprises reinforced concrete post 1, and the lower end of reinforced concrete post 1 is rigidly connected with basis 4, and the upper end of reinforced concrete post 1 and steel column 2 are rigidly connected, and the other end of steel column 2 connects girder steel 3.
Be rigidly connected with high-strength bolt between reinforced concrete post 1 and steel column 2, steel column 2 and the girder steel 3 and between the girder steel 3.
The utility model has utilized the big advantage of prefabricated reinforced concrete column rigidity very dexterously, the lower prop that transmits crane load is designed to prefabricated reinforced concrete column, crane girder 500mm is designed to steel column with upper prop, roof system is girder steel and profiled sheet, roof system part is compared with large roof slab with the prefabricated roof truss of traditional structure have quick construction, characteristics aesthetic in appearance, also reached the purpose of saving investment.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Embodiment of the present utility model: 500mm is a prefabricated reinforced concrete column 1 on from the basis section of anchoring into to the crane runway absolute altitude, from prefabricated capital to roofing cornice is steel column 2, be rigidly connected by high-strength bolt between prefabricated reinforced concrete column 1 and the steel column 2, steel column 2 is rigidly connected with girder steel 3 usefulness high-strength bolts, be rigidly connected with high-strength bolt between the girder steel 3, prefabricated reinforced concrete 1 is rigidly connected with basis 4, so just forms a kind of novel individual layer and mixes bent structure.
