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 by the upper flat plate that be arranged in parallel up and down 3 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 and Section Point plate 1 ' are welded with chord member 10 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: as described in Fig. 3 and Fig. 4, the structure of present embodiment is substantially the same manner as Example 1, different is: be welded with first internal partition 5, second internal partition 4 and the 3rd internal partition 5 ' that is set parallel to each other between the upper flat plate 3 and following 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: as Fig. 5, Fig. 6, Fig. 7 and triangular truss node structure shown in Figure 8, the structure of present embodiment is substantially the same manner as Example 2, 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, between second internal partition 4 and the 3rd internal partition 5 ', be provided with the second upper flat plate through hole 32, first internal partition 5, be respectively arranged with the first internal partition through hole 51 on second internal partition 4 and the 3rd internal partition 5 ', the position of the second internal partition through hole 41 and the 3rd internal partition through hole 51 ', the second internal partition through hole 41 is higher than the first internal partition through hole 51 and the 3rd internal partition through hole 51 '.
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 connection 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, be provided with the montant attachment weld on the circular arc of the first node plate of full welding integral node and Section Point plate radius maximum, this attachment weld place can weld with montant, therefore 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 utility model in detail.Should be appreciated that those of ordinary skill in the art need not creative work and just can make many modifications and variations according to design of the present utility model.Therefore, all technician in the art comply with design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be in the determined protection domain by claims.
