The specific embodiment
Embodiment 1: as depicted in figs. 1 and 2, a kind of full welding integral node comprises first node plate 1 and Section Point plate 1 ', and first node plate 1 and Section Point plate 1 ' are through the upper flat plate 3 that laterally arranges up and down and dull and stereotyped 2 structures that are welded into a whole down.The right side of first node plate 1 and Section Point plate 1 ' is provided with chord member attachment weld 7, and first node plate 1 is welded with chord member 10 with Section Point plate 1 ' at chord member attachment weld 7 places.Chord member 10 is welded to after the gusset plate, and directly dispatching from the factory gets final product.
Because first node plate 1, Section Point plate 1 ', upper flat plate 3, following flat board 2 and chord member 10 are that integrally welded structure is dispatched from the factory, so this node overall performance is good, bearing capacity is big, and easy construction, uses high-strength bolt few.
Embodiment 2: of Fig. 3 and Fig. 4; The structure of present embodiment and embodiment 1 are basic identical; Different is: upper flat plate 3 and be welded with down first internal partition 5, second internal partition 4 and the 3rd internal partition 5 ' of parallel setting between dull and stereotyped 2; Upper flat plate 2 is welded with external partition 11 over against second internal partition, 4 places, and each internal partition is vertical with following dull and stereotyped 2 with upper flat plate 3 with external partition; The left side of first node plate 1 and Section Point plate 1 ' also is provided with chord member attachment weld 7, and this chord member attachment weld place is welded with chord member 10.
Other structures of present embodiment are identical with embodiment 1 with operating principle, but owing to weld together with the chord member one in internal partition, external partition and left side, so performance is better than embodiment 1.
Embodiment 3: like Fig. 5, Fig. 6, Fig. 7 and triangular truss node structure shown in Figure 8; The structure of present embodiment and embodiment 2 are basic identical; Different is; Upper flat plate 3 is provided with the first upper flat plate through hole 31 between first internal partition 5 and second internal partition 4; Be higher than the first internal partition through hole 51 and the 3rd internal partition through hole 51 ' being provided with the position that is respectively arranged with the first internal partition through hole 51, the second internal partition through hole 41 and the 3rd internal partition through hole 51 ', the second internal partition through hole 41 on the second upper flat plate through hole, 32, the first internal partitions 5, second internal partition 4 and the 3rd internal partition 5 ' between second internal partition 4 and the 3rd internal partition 5 '.
In the present embodiment, having welded two chord members on the node, in other specific embodiment, also can be two nodes of welding on the chord member, to reach essentially identical technique effect.
Other structures of present embodiment are identical with embodiment 1 with operating principle, but because the setting of bulkhead through-hole, ribs, and together with the welding of cross-beam connecting plate 8 peace couplet gusset plates 9 one, so performance is better than embodiment 2.
Embodiment 4: the structure of present embodiment is identical with embodiment 3; Different is; On the maximum circular arc of the first node plate of full welding integral node and Section Point plate radius, be provided with the montant attachment weld, this attachment weld place can weld with montant, so can be made into N type panel point.Other structures of present embodiment are identical with embodiment 3.
More than describe preferred embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art need not creative work and just can design according to the present invention make many modifications and variation.Therefore, all technician in the art all should be in the determined protection domain by claims under this invention's idea on the basis of existing technology through the available technical scheme of logical analysis, reasoning, or a limited experiment.
