Abstract
The utility model discloses a node of a single-layer box-type section curved reticulated shell. The node of the single-layer box-type section curved reticulated shell comprises a round pipe in the central position of the node, reinforced plates in the round pipe and a plurality of box-type section rod pieces, wherein the box-type section rod pieces are connected with the round pipe in the central position of the node through communicated welding seams, and the round reinforced plates are additionally arranged in identical positions of flanges of the box-type section rod pieces inside the round pipe in the central position of the node and in the middle of the round pipe in the central position of the node. According to the node of the single-layer box-type section curved reticulated shell, the transmission of force of the structure is definite and direct, the welding quality is controllable, and the requirement of stress of the structure is fully met. The directional problem of box-type section components in a complex curve is resolved, the machining in factory and construction on site are convenient and simple, the problem that the construction cost is increased caused by adoption of cast steel nodes is avoided, and therefore the node of the single-layer box-type section curved reticulated shell is especially suitable for being used in the structure of the box-type section single-layer reticulated shell with a special curve shape in a building.
Description
Technical field
The utility model relates to and belongs to the steel construction member, and is special relevant with a kind of individual layer box-type section surface net shell node.
Background technology
Tradition latticed shell structure rod member is main mainly with round steel pipe, and the rod member internal force of structure is main mainly with axle power.Along with the raising of china's overall national strength, the domestic construction structure presents towards large span more, more large tracts of land, the more aspect development such as complexity body, and the net shell rod member under the new build has also born sizable Moment except axle power.The box-type section rod member is because of its preferably bending resistance, torsional property, and its corner angle are clearly demarcated in addition, and it is beautiful to present good mechanics, is subject to increasing architect parent and looks at, and uses more and more extensive in the characters for big span space grid truss such as theater, stadiums.
Along with popularizing that the box-type section rod member is used in large inter-network shell structure, thing followed node problems becomes a great problem.The node of box-type section rod member net shell also need be considered the Moment that it bears except routine is born the effect of axle power.Present stage for this kind node direct tubular joint, welded hollow spherical joints or cast steel nodes of adopting more.For welding hollowing ball, present research is all for cooperating round steel pipe, the welded spherical node that cooperates rectangular tube be there is no correlative study, whether solder sphere can reach fully desirable rigidly connecting, bear the larger Moment of Nodes and be still waiting further research, for box-shaped section component, with the intersection very complex of solder sphere junction, processing and installation difficulty are all larger simultaneously.For adopting direct tubular joint, because the box-type section rod member is different from pipe, there is directionality, for building the peculiar single-layer lattice shell of surface modeling, box-shaped section component presents the bending performance, adopts directly to pass through mutually processing, has all proposed higher requirement for the processing and fabricating of detail drawing, factory and the construction at scene, and often exist the phenomenon that installation accuracy is low, welding quality is bad, the processing and fabricating cost of box-type section bending component increases substantially simultaneously.And the employing cast steel node, although can solve well the problem that occurs in the tubular joint, yet for number of nodes the large and various situation of node pattern, it is long that cast steel node often exists the process-cycle, the problem that project cost is high.
The utility model content
The purpose of this utility model provides a kind of individual layer box-type section surface net shell node, and the power transmission of structure is clear and definite, direct, and weldquality has controllability, can fully satisfy the requirement of structure stress.Solved simultaneously the directional problems of complex-curved middle box-shaped section component, factory process and site operation are convenient and simple, the problem that the construction costs of having avoided adopting cast steel node and having caused increases is specially adapted to build in the peculiar box-type section single-layer lattice shell structure of surface modeling.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
Individual layer box-type section surface net shell node comprises stiffener and some box-type section rod members of node center place pipe, pipe inside; The box-type section rod member is connected with node center place pipe by passing through mutually weld seam, and pipe inside, node center place adds circular stiffener in box-type section rod member edge of a wing same position and node center place pipe middle part.
Described box-type section rod member is positioned at same curved surface.
Described same curved surface is plane, sphere, ellipsoid, the face of cylinder or hyperboloid.
Described box-type section rod member quantity is 2～8.
After adopting such scheme, the utlity model has many beneficial effects:
One, drawing in-depth, processing and fabricating are conveniently.The utility model so that the bending performance of member realize by node, member itself can be made by common box-shaped section component, greatly reduce the requirement of in-depth, plant equipment and technique to drawing, in the situation of saving cost, greatly improved the progress of engineering.
Two, work progress is convenient, safe and reliable, installation accuracy is high.The utility model has enlarged node region, greatly reduced the problem that the Nodes weld seam is intensive, weldquality is difficult to guarantee that causes because of node region the number of components more, solve simultaneously the misalignment problem that box-shaped section component occurs easily, reduced the site operation difficulty.
Three, ultimate bearing capacity of joints is high.The power transmission of the utility model welding node is clear and definite, direct, and weldquality has controllability, and ultimate bearing capacity of joints is high, can avoid the weld seam brittle fracture to destroy prior to steel simultaneously, guarantees that structure has good ductility.
Four, can form standardized production.By the otherness of the utility model solution because of the peculiar great deal of nodes existence that causes of architectural image, make node can form standard pattern, batch production.

The specific embodiment
By reference to the accompanying drawings, preferred embodiment is described in further details to the utility model.
Individual layer box-type section surface net shell node comprises stiffener 3 and some box-type section rod members 1 of node center place pipe 2, pipe inside.
Box section bar part 1 is 4 in the present embodiment, is to utilize machine to cut out the intersection termination, links to each other with node center place pipe 2 by complete molten butt weld 4.Stiffener 3 matches with the internal diameter size of node center place pipe 2, links to each other with node center place pipe 2 by strength plate fillet weld 5.Each box-shaped section component 1 axis place curved surface can be plane, sphere, ellipsoid, the face of cylinder or hyperboloid.
Above-described embodiment only is used for explaining inventive concept of the present utility model; but not to the restriction of the utility model rights protection; allly utilize this design that the utility model is carried out the change of unsubstantiality; such as suitable increase and decrease of box-type section rod member 1 quantity etc., all should fall into protection domain of the present utility model.
