Description
Technical field
The utility model relates to a kind of cast steel node, is specifically related to the heavy steel Steel Cantilever of a kind of large span Y shape beam column frame cast steel node.
Background technology
Long-Span Steel Space Structures is weighed the important symbol of a country Building technology level often, its form of structure mainly contains five large spatial structures and all kinds of interblock space structures such as space truss structure, latticed shell structure, suspended-cable structure, membrane structure, thin shell structures, and the space structures come in every shape is used widely in the buildings such as stadiums, conference and exhibition center, cinema, megastore, factory floor.The large public building of building has in recent years all adopted the tube truss structure of the direct junction of steel tube member bar mostly, and its profile is abundant, structure is light and handy, and power transmission is simple and direct, fabrication and installation are convenient, good economical benefit, is the more a kind of structural system of current application.But the scope of application is restricted, the construction period is long, simultaneously various because of its structural element quantity specifications, the production management difficulty, and its outward appearance and inner visual effect are difficult to control, and build attractive in appearance being difficult to and hold.Therefore need to be improved this technology, be increased its scope of application, be reduced the construction period.
The utility model content
The purpose of this utility model is, the heavy steel Steel Cantilever of a kind of large span Y shape beam column frame cast steel node, realized the natural transition of heavy beam column of steel structure type of attachment, to overcome the existing above-mentioned shortcoming and defect of prior art.
A kind of cast steel node, comprise: node main body and linking arm, wherein said linking arm comprises: vertical column linking arm, oblique beam linking arm and middle pectoral plate, take the center of middle pectoral plate and connect respectively two oblique beam linking arms as symmetric points in top, the both sides of described node main body, the down either side of described node main body is connected with the vertical column linking arm, between described oblique beam linking arm and horizontal plane, has an inclination angle made progress.
Further, described node main body and linking arm are the integral type structure.
Further, described node main body comprises: peripheral board and internal web, and described peripheral board is node main body external frame, described internal web is located at the node body interior.
Further, the below of the junction between one side of described middle pectoral plate and two oblique beam linking arms is fixedly connected with.
The beneficial effects of the utility model:
1, the scope of application is large, the construction period is short, because of it, be full cast steel structure simultaneously, its high conformity, quality is secure, the convenient installation, stress performance is good, economy is better, the application of cast steel node in large span space building structure is achieved, because cast steel node has been manufactured in factory, greatly reduced the workload of work high above the ground, building costs is reduced, and the integrated engineering quality improves, and greatly reduces the harm that work high above the ground brings the constructor.
But 2 flexible Application are in the Heavy Type Steel Structure of the multi-direction connection of complexity, design that multiple stress performance is good, casting technique simple, the steel-casting of outward appearance and inner good visual effect.
The accompanying drawing explanation
Fig. 1 is external structure figure of the present utility model.
Fig. 2 is inner structure figure of the present utility model.
Reference numeral:
Node main body 100, peripheral board 110 and internal web 120.
Linking arm 200, vertical column linking arm 210, oblique beam linking arm 220, middle pectoral plate 230.
The specific embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.Should be understood that following examples are only for the utility model is described but not for limiting scope of the present utility model.
Embodiment 1
Fig. 1 is external structure figure of the present utility model.Fig. 2 is inner structure figure of the present utility model.
As shown in Figure 1, a kind of cast steel node, comprise: node main body 100 and linking arm 200, node main body 100 and linking arm 200 are the integral type structure, linking arm 200 comprises: vertical column linking arm 210, oblique beam linking arm 220 and middle pectoral plate 230, take middle pectoral plate 230 center and connect respectively two oblique beam linking arms 220 as symmetric points in top, the both sides of node main body 100, form " Y " font structure, the below of the junction between one side of middle pectoral plate 230 and two oblique beam linking arms 220 is fixedly connected with, the down either side of node main body 100 is connected with vertical column linking arm 210, there is an inclination angle made progress between oblique beam linking arm 220 and horizontal plane.
As shown in Figure 2, wherein, node main body 100 comprises: peripheral board 110 and internal web 120, and peripheral board 110 is node main body 100 external frame, internal web 120 is located at node main body 100 inside.Peripheral board 110 divides face local thickening according to stress, and stress performance is good, casting technique is simple, economy is better.Its outward appearance and inner good visual effect, build attractive in appearance, good product consistency, quality is secure, stress performance is good, this design realizes that list docks with the cantilever twin beams, simplifies the structure and makes, and has solved the overlapping thermal stresses caused of intersection's weld seam, solve this stress complex state simultaneously, guaranteed the safety of junction and the nature of moulding.
The utility model method for designing is also very simple, at first according to modeling requirement design peripheral board 110, then determine the position of internal web 120 according to force analysis, finally by finite element analysis, determine panel thickness, and thickness and length and the method for arranging of internal web 120; But flexible Application is in the Heavy Type Steel Structure of the multi-direction connection of complexity, design that multiple stress performance is good, casting technique simple, the steel-casting of outward appearance and inner good visual effect.
With traditional technology, compare, the utility model is simple except method for designing, also comprises: the scope of application is large, the construction period is short, can be used in different field, adopt different welding manners.Because the utility model is all steel integral structure, no matter its outward appearance is inner or outside, and good visual effect is built attractive in appearancely, and good product consistency, compare with traditional many parts cast steel node, and this integral structure management is convenient also more attractive in appearance.Simultaneously, the utility model is installed simple, stress performance is good, casting technique is simple, economy is better, the application of cast steel node in super-high building structure is achieved, because cast steel node has been manufactured in factory, greatly reduced the workload of work high above the ground, building costs is reduced, the integrated engineering quality improves, and greatly reduces the harm that work high above the ground brings the constructor.
Above the specific embodiment of the present utility model is illustrated, but the utility model is as limit, only otherwise break away from aim of the present utility model, the utility model can also have various variations.
