Description
Technical field
The present invention relates to a kind of assembling bar element for large span lattice network.
Background technology
Large span network is since last century, the eighties was introduced from Germany, be widely used in long span building engineering, as airport building, stadiums, the engineerings such as museum, the network extensively adopted at present is rack (net shell) structure, its Types of nodes is bar-ball-bar connected mode, namely each root bar is connected with ball, each root rod member is not spatially all at same position, a ball is connected with several bar, composition space is interconnected the tension and compression rod member spherical structure that is mutually related, this structure space good integrity, be applicable to very much crossing over spatial extent to have certain requirements structure.But the span of this network also has a definite limitation, for bolt-ball net frame (net shell), because the rod member of existing bolt-ball net frame, what adopt is that each root rod member is connected with bolt sphere by a bolt, for every root rod member, the pulling force of a rod member all passes to bolt sphere by a bolt, and along with rack (net shell) span increases, the power of bearing also increases by bolt.Because bolt is high-strength material, manufacturing process determines the diameter of bolt and is generally less than 64mm, if the diameter of bolt is greater than 64mm, manufacturing process is difficult to the quality ensureing bolt, thus the span of restrained force bolt-ball net frame.If every root member design is greater than a bolt in bolt sphere, the diameter of bolt sphere will increase considerably, and bolt sphere is medicine ball, and bolt sphere weight is the cubic relationship of diameter, and bolt-ball net frame weight significantly increases, cost increase.
Solder sphere rack (net shell) overcomes the shortcoming of bolt-ball net frame, and span can design larger than bolt-ball net frame (net shell), but along with the increase of span, the quantity of material exponentially of structure increases, and structure is uneconomical.For Space Trusses In Plan, general span is below 60 meters, for housing space truss structure, span is also limited to less than 120 meters, be greater than this span, due to the relation exponent function relation of structure between metal material doses and span, cause metal material doses to be increased with the increase exponentially of span, structural cost significantly promotes, and infrastructure cost is high.
Publication date is on December 9th, 2009, publication number is the cylindrical surface compound rods giant grid structure that the utility model patent of CN201358513 discloses a kind of super-span, the agent structure of this utility model is a kind of macrolattice structure be made up of latticed members, its size of mesh opening is 10 ~ 30m, the rod member of traditional welding ball and bolt-ball net frame (net shell) replaces with welding latticed pole by this utility model, effectively can overcome the problem of strut buckling, integral rigidity and the stability of structure can be increased substantially, avoid strut buckling, like this can cross-domain larger span, save steel using amount, reduce construction costs, be applicable to the super-span space net shell roof structure of more than 200m.The conehead of latticed pole is connected respectively at solder sphere by each point of strut piece by this utility model, because each point of strut piece has certain thickness respectively, if do not pass through connection mutually between each point of strut piece, namely each point of strut piece keeps the section area of former each point of strut piece constant without any cutting, namely each point of strut piece is connected with solder sphere respectively, 200 meters with upper span time, the size of solder sphere reaches more than 1200mm, most of solder sphere diameter reaches 1500mm, and other bulb diameter individual reaches more than 2000mm.So far, the specification of more than solder sphere 900mm lacks bearing capacity experimental data, and solder sphere large so is also difficult to make, and so large solder sphere also considerably increases the weight of solder sphere, causes total very uneconomical.The utility model is connected with solder sphere after each point of strut piece is passed through connection mutually, be connected with solder sphere after cutting a part by each branch bar cross section, Ze Ge branch cross-sectional strength can not be guaranteed, total degree of safety is caused to reduce, through a large amount of calculating simulation, this utility model only can be used in span and be greater than in the shell structures such as the structure cylinder of 200 meters, material is saved than solder sphere or bolt-ball net frame (net shell), be difficult to be applied in the most frequently used dull and stereotyped network, reason is that the solder sphere diameter that slabbed construction calculates is larger.
To sum up, the safety that is high and total of the lattice network cost of existing large span is low.
Summary of the invention
The present invention is that the lattice network solving existing large span exists the low problem of cost safety that is high and total, and then provides a kind of assembling bar element for large span lattice network.
The present invention solves the problems of the technologies described above the technical scheme taked to be:
Assembling bar element for large span lattice network of the present invention comprises two metal solder spheroids, six or eight pieces points of poles and grid rod member, described Lattice Structure Members unit also comprises two selector bars, one end of each metal solder spheroid and a selector bar is welded as a whole, every one end of grid rod member is all welded with one end of three or four pieces points of poles, three or the other end of four pieces points of poles be welded on corresponding selector bar along the circumferencial direction of selector bar is uniform, three or four pieces points of poles of every one end are umbrella branch; Described assembling bar element also comprises multiple flange and multiple gusset plate, and every root grid mobile jib of grid rod member is by least one Flange joint, and each selector bar is by a Flange joint, and multiple gusset plate is uniform to be welded on every root grid mobile jib of grid rod member.
The present invention has following beneficial effect:
Assembling bar element for large span lattice network of the present invention is connected with a point pole by selector bar, namely by selector bar connection metal welding spheroid and multiple points of poles, ball node adopts welded spherical node, compared with the lattice network of existing large span, lattice grid rod member of the present invention is not directly be connected with welding spheroid by point pole, and be through after selector bar welds with solder sphere, be connected with a point pole by bridgeware, effectively reduce the diameter of metal solder spheroid, thus greatly reduce metal material consumption, metal material consumption decreases more than 30%, rod member of the present invention makes and conehead welding job all completes in factory, only there are assembling and lifting work in job site, workmanship obtains abundant guarantee, greatly save site work amount, with entirely weld compared with lattice component, greatly reduce construction costs, construction costs reduces more than 20%,
The present invention's each point of pole is welded with selector bar and is cut without cross section, thus improves the safety of total;
The present invention be applicable to span be greater than 60 meters dull and stereotyped network, cylinder grid, Grid, shape of a saddle grid and other typical surface meshes, and atypia surface mesh structure, namely save material than common solder sphere or bolt-ball net frame (net shell).
