The specific embodiment
Be described in further detail below in conjunction with the enforcement of accompanying drawing the cast steel node structure:
See also shown in Figure 1ly, be polyhedron cast steel node schematic diagram; As can be seen from the figure, 1 is longitudinal stiffener, and 2 is hole, and 3 is the horizontal stiffening rib in upper end, and 4 is the horizontal stiffening rib in lower end, and 5 is polyhedron cast steel wall.
Fig. 2 is the generalized section of polyhedron cast steel node, and Fig. 3 is an A-A generalized section among Fig. 1, and Fig. 4 is a B-B generalized section among Fig. 1, and Fig. 5 is a C-C generalized section among Fig. 1.
As shown in FIG., polyhedron cast steel switching node is made up of for the geometric space of several polygon steel walls 5 profile; The limit number that the cast steel node geometric configuration adopts, corresponding with the geometrical edge number of institute connection pillar; Described cast steel node upper port cross section is corresponding with the member shape that is connected; The cross sectional shape at its node lower port place is corresponding with the member shape that is connected; In polyhedron cast steel node upper end horizontal stiffening rib 3 is set, its lower end is provided with the horizontal stiffening rib 4 of the horizontal component of bearing the sloped sidewall generation, and the longitudinal stiffener 1 that improves the steel-casting sidewall stability is set in the longitudinal cross-section of cast steel node.Horizontal stiffening rib 3 in upper end and the horizontal stiffening rib 4 in lower end are provided with hole 2.Steel wall 5, the junction is chamfered between wall, and side seam is set simultaneously at steel-casting upper end open place and weld seam is filled at the back.
The wall thickness of cast steel node should not be crossed thin also unsuitable blocked up, crosses thin the entering in the chamber of molten steel uniform and stable of can not guaranteeing, blocked up cast steel will cause the waste of steel.For the horizontal component event of bearing the sloped sidewall generation all is provided with horizontal stiffening rib 4 in the upper and lower end of polyhedron cast steel node,, improve the rigidity of cast steel node to guarantee the resistance to overturning of sidewall.Consider that part cast steel node yardstick is bigger, the member wall thickness is thinner relatively, also longitudinal stiffener 1 should be set, design during longitudinal stiffener 1 except that considering joint structure characteristics and stress performance requirement, also should be in conjunction with the casting technique requirement, the assurance MOLTEN STEEL FLOW is smooth and easy, and inside and outside heat radiation is even, effectively avoids the cast steel node internal flaw.
Between cast steel node sloped sidewall and the vertical sidewall, it is smooth and easy that node inwall and outer wall will adopt chamfering to make that internal force transmits, and when avoiding stress to concentrate, also has the good surface appearance effect.Take all factors into consideration that scarfing cinder in the casting engineering requires and the requirement of field Welding, can at the horizontal stiffening rib of upper and lower end place hole 2 be set respectively.
Steel-casting and being connected of adjacent members are important steps in the cast steel node design.Owing to answer dynamics higher, the intensity of member steel should be higher than cast steel material, so the steel-casting wall thickness is generally greater than the wall thickness of member.If steel pipe and steel-casting are directly welded, certainly will produce bigger welding stress herein, internal force evenly transmits between Materials with High Strength and the low strong material in order to make, and avoids producing the stress raisers phenomenon, so will do the welding notch at the weld of cast steel node and steel pipe.If can directly the cast steel wall thickness be smoothly transitted into suitable wall thickness when the wall thickness of cast steel node and steel pipe is more or less the same with steel pipe, will be on steel-casting when if cast steel wall thickness and steel pipe differ big end interface side seam is set simultaneously fill weld seam with the back, with the higher stress in the assurance steel member can effectively be diffused as in the steel-casting than low stress.For the lower port of polyhedron steel-casting,,, steel-casting lower port and member get final product so only being provided with side seam because stress is lower.
