The specific embodiment
The invention will be further described below in conjunction with drawings and Examples:
As shown in Figure 2, the lightgage steel joist of this no fitting system, comprise carrying keel 7, dragon 9 in connecing, with suspension rod 5, described suspension rod 5 is fixedlyed connected with carrying keel 7 by the connecting hole 7-1 at carrying keel 7 tops, carrying keel 7 bottoms are provided with one group of draw-in groove 7-2, dragon 9 is provided with draw-in groove 7-2 and is the middle Long Card groove 13 that clamping cooperates in connecing, carrying keel 7 and carrying keel 7 laterally between by imperial 9 being connected in connecing certainly, be the self-couplings syndeton between carrying keel 7 and carrying keel 7 vertical, the self-couplings syndeton comprises and is first clamping, 14 and second clamping that clamping cooperates 15, first clamping, 14 both sides are provided with first inserted sheet 16 that protracts, the both sides of second clamping 15 are provided with second inserted sheet 17 that protracts, the inside, both sides that the outside, both sides of first clamping 14 is provided with second inserted sheet 17 is first Plug Division, 18, the second clampings that cooperate 15 of pegging graft is provided with and can be second Plug Division 19 that grafting cooperates with first inserted sheet 16.
As Fig. 5-shown in Figure 8, describedly be the self-couplings syndeton between dragon 9 and dragon 9 in connecing vertical in connect, imperial joint A11 and middle imperial joint B12 in comprising, in imperial joint A11 and middle imperial joint B12 be plug-in type and be connected, middle imperial joint B12 peg graft the cross sectional shape size of part be slightly smaller than in the grafting part of imperial joint A11.
