Embodiment
With reference to attached drawing 1-3, the embodiment of the present invention is described in further details.
As shown in Figure 1, a kind of device top roof structure for improving ball hinged support node anti-pulling capacity uses rack knot
Configuration formula, 1 diameter 2m of net rack support solder sphere, solder sphere 1 vertical section height 750mm, solder sphere thickness 100mm.Solder sphere 1 is logical
Cross ball hinged support 10 to be connected with steel column 4,4 specification of steel column is P1600x40.10 upper bracket plate 2 of ball hinged support is rectangle, with welding
Ball 1 is connected using full penetration weld, and 3 lower surface of lower support plate is circle, is connected with 4 abacus of steel column using partial penetration weld seam
Connect.Steel column 4 by 10 node of ball hinged support bear roof system rack be transmitted through come load and pass it to basis.
Since roof system rack by ball hinged support 10 is supported on the top of steel column 4, roof system grid structure span is big, ball hinged support
10 as crucial force transferring structure, its stress is big, so setting resistance to plucking reinforcing pull rod 6, its power transmission is direct, effectively raises node
Resistance to plucking load-carrying properties and the ability for resisting angular displacement, node overall stiffness improve, and limit corner displacement excessive at node, at the same time
Limit the larger deformation of top roof structure.
Resistance to plucking is realized by resistance to plucking reinforcing pull rod 6, connection otic placode 5 and box-shaped bracket 7, and resistance to plucking reinforcing pull rod 6 uses UI shapes
