In order to realize the foregoing invention purpose, the utility model adopts following technical scheme:
A kind of roof system supports and the i iron purlin structure that is connected, have some steel roof truss structures and connect and compose the netted structure that is connected with some roof system braced structuress, described steel roof truss structure is winded up by steel roof truss and 1 is intersected vertical the connection with purlin 2, and wind up four jiaos of 1 nodes that is connected of purlin 2 and steel roof truss tilt to be connected with roof system support bar 4 by shaped steel spare 5, junction plate 6; Described roof system braced structures is intersected vertical the connection with purlin 2 by tie-beam 3, and four jiaos of the nodes that are connected with tie-beam 3 of purlin 2, tilts to be connected with roof system support bar 4 by junction plate 6;
Wherein, the shaped steel spare 5 of steel roof truss structure is fixed on steel roof truss and winds up on 1, and shaped steel spare 5 and steel roof truss wind up 1, and to connect and compose its cross section be the rectangular cavities structure;
Wherein, the junction plate 6 of roof system braced structures is fixed on the bottom wing of tie-beam 3.
A kind of roof system supports and the i iron purlin structure that is connected, and the described steel roof truss 1 angle steel limit by two angle steel of winding up connects and composes, wherein another angle steel limit in one plane, its cross section structure is " fourth " font.
A kind of roof system supports and the i iron purlin structure that is connected, and described shaped steel spare 5 its cross section structures are " fourth " font.
A kind of roof system supports and the i iron purlin structure that is connected, and described purlin 2 is i iron.
Because adopt aforesaid technical scheme, the utility model produces following good effect:
1, making the purlin double as is that depression bar is avoided upper chord of roof truss side direction unstability, but simultaneously this purlin and tie-beam also double as be the tie-rod that roof system supports, roofing Support lattice are divided into economy and applicability size preferably, convenient simple structure are set.
2, this structure connects when making, and connects the shaped steel spare of purlin and can be in advance welds at the steel roof truss angle steel that winds up, and processes simple and easyly, has reduced the manufacturing processing cost.
