Abstract
The utility model relates to a steel-structure double curved surface reticulated shell node. The steel-structure double curved surface reticulated shell node comprises an upper flange plate and a lower flange plate, wherein a node structure formed by a plurality of bracket ends is fixedly formed between the upper flange plate and the lower flange plate through webs in a welding mode. Head plates are arranged at the front ends of the bracket ends and fixedly connected with bracket flanges and the webs. The node structure is provided with six bracket ends, and turning angles and torsional angles of six brackets are all different. The steel-structure double curved surface reticulated shell node is a curved surface transition integrated body, and used for special-shaped monolayer reticulated shell formed by triangular meshes in a sun valley which are greatly overhung and irregular in space, so that the triangular meshes can be integrated into a smooth flat surface shape, and the integral shape of a sun valley is perfect.
Description
Technical field
The utility model relates to a kind of individual layer hyperbolic paraboloid steel work net shell, especially a kind of node structure for individual layer hyperbolic paraboloid steel work net shell.
Background technology
Expo axle sunlight paddy is totally 6 paddy, and the profile of every paddy all becomes goblet shape or claims tubaeformly, and the bottom is little, and top is big, but every paddy all is non-centrosymmetrical special-shaped hyperbolic curved surface.Its structural system adopts individual layer hyperbolic paraboloid steel work net shell.The net shell is formed triangular unit by the rod member and the node that adopt the square-section, the steel structure node of connection rod member, and none is identical because of the variation of closure, angle.Stress ratio adopts variable cross-section rectangle rod member than large part, chooses outstanding, the irregular form in space greatly in order to constitute " sunlight paddy ", and structural system is defined as the special-shaped single-layer lattice shell be made up of triangular mesh, and ultrawhite doubling safety glass is embedded in the triangular mesh.Because form irregular curved body, triangle is the shape that preferably can be integrated into smooth flat, makes the moulded more perfect of " sunlight paddy ".Therefore, need a kind of node structure for individual layer hyperbolic paraboloid steel work net shell.
Summary of the invention
The utility model provides a cover steel work hyperboloid net shell node at the requirement of sunlight paddy latticed shell structure node.
The technical solution of the utility model is: a kind of steel work hyperboloid net shell node, comprise upper and lower frange plate, and fix node structure of being formed by several " bracket " terminations of formation by the web welding between the upper and lower frange plate.
" bracket " termination front end is provided with head plate, and head plate is fixedlyed connected with " bracket " edge of a wing and web.All " bracket " terminations inequality of six corners, torsional angle are arranged in the node structure.
The beneficial effects of the utility model are:
Expo axle sunlight paddy is totally 6 paddy, and the profile of every paddy all becomes goblet shape or claims tubaeformly, and the bottom is little, and top is big, but every paddy all is non-centrosymmetrical special-shaped hyperbolic curved surface.Its structural system adopts individual layer hyperbolic paraboloid steel work net shell.The net shell is formed triangular unit by the rod member and the node that adopt the square-section, the steel structure nodes of 10348 connection rod members, and none is identical because of the variation of closure, angle.Stress ratio adopts variable cross-section rectangle rod member than large part, and namely the net thickness of the shell does not wait.
The utility model is used for " sunlight paddy " and chooses special-shaped single-layer lattice shell outstanding, that the irregular triangular mesh in space is formed greatly, makes triangular mesh be integrated into the shape of smooth flat, " sunlight paddy " moulded more perfect.
Description of drawings
Fig. 1 is structural upright schematic diagram of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of steel work hyperboloid net shell node comprises upper and lower frange plate 1,2, web 3, head plate 4 etc.
Fix node structure of being formed by several " bracket " terminations of formation by web 3 welding between the upper and lower frange plate 1,2.All " bracket " terminations inequality of six corners, torsional angle are arranged in the node structure.
As shown in Figure 2, " bracket " termination front end is provided with head plate 4, and head plate 4 is fixedlyed connected with " bracket " edge of a wing and web 3.
Requirement according to structure of the present utility model, the wherein top flange plate of node area and bottom wing listrium, web keeps not bending of plane.Be about to node and be divided into the upper and lower edge of a wing and web, will go up the location that bottom flange bending (hot bending) realizes the control point, bottom flange respectively by the two-axis numerical control bender.Again web is assembled into complete node, welding fabrication.
Manufacturing process of the present utility model:
(1) data of utilizing computer to finish machining control point are handled;
(2) select numerical control bender, numerical control end surface to mill numerically controlled processing equipments such as machine, three-dimensional measuring instrument, determine node, rod member processing process and technological parameter.
(3) after the upper and lower frange plate Numerical control cutting, carry out bending again and utilize distinctive two-axis numerical control bender to carry out numerical control bending.
(4) on working platform the workpiece bed hedgehopping, the morpheme size accurate adjustment that upper and lower wing plate bending is shaped puts in place.
(5) check the web bevel angle, finish must be mended mill as defectiveness, and will polish metallic luster in the 30mm scope of groove zone, assembling 8x30 billet, and backing plate and web tacking should be welded in the back side, must not weld at groove face.
(6) open a grade size between the upper and lower wing plate of inspection, assemble first block of web.Can't pack into if note web, must not the mowing backing plate, should split shelves and do suitably to adjust, after web is packed into, check gap between web and dividing plate.
(7) identical with the previous step assemble method, continue assembling remaining three with every the web that links to each other, behind the tacking, weld the groove weld between web and dividing plate.Notice during welding that symmetry carries out, detect the distortion situation at any time.
(8) continue all the other eight blocks of webs of assembling, backing plate exceeds web can suitably lengthening near central side, to guarantee the continuity of weld seam.
(9) assembling termination shrouding, head plate must be vertical with center, top flange lead-out wire and guarantee not have concave surface behind the building up by welding.
The utility model back that completes adopts three-dimensional coordinate measuring instrument that node is done last accurate measurement, with three-dimensional coordinate instrument each node in the sunlight paddy latticed shell structure is detected and the precision of guaranteeing the control point in allowed band.Three-dimensional coordinate instrument is the instrument that the implementation space coordinate point detects.It detects error is 0.01mm.
Be directed to the characteristics of sunlight paddy latticed shell structure, requirement according to structure, node adopts bending " bracket " type node, the node area of square tube junction just is welded by steel plate, wherein the top flange plate of node area and bottom wing listrium are whole plate blanking cutting and form, the frange plate up and down of " bracket " section is the hot bending plate, seamlessly transits to joint cores from " bracket " port, and web keeps not bending of plane.
