Description
Technical field
The present invention relates to a kind of aluminium alloy space structure node, the particularly widened aluminium alloy space in a kind of connecting rod edge of a wing
Structure node.
Background technology
Aluminum alloy materials belongs to a kind of New Building Materials, have, corrosion resistance and good high, attractive in appearance from heavy and light, specific strength,
Can be extruded etc. advantage, be initially widely used at aerospace field, this kind of material has been introduced in building subsequently
Engineering field, is also widely popularized.Aluminium alloy is compared with steel, and density is only the 1/3 of steel, and slim and graceful structural system has
Being beneficial to Aseismic Design, the reduction simultaneously conducted oneself with dignity reduces the burden of lower seat, and this advantage is in large-span space structure
Becoming apparent from, especially in today that large-span space structure is fast-developing, aluminium alloy is just embodying its superiority, is having
Vast potential for future development.
The domestic research for aluminium alloy is started late, and external research starts from the fifties, and current achievement in research is relative to one-tenth
Ripe.In recent years, the research steps of aluminium alloy is accelerated by China, research contents the most extensively, domestic
Through having built up more than 10 seat large aluminum alloy space structures.Nowadays, aluminium alloy structure has become as and is only second to the important of steel construction
Building structure.
For a space structure, space structure is the most stable, construction and installation are the most convenient, whether cost height accords with
Close and require all to there are close ties with node.At present, the node being most widely used in aluminium alloy space structure is that aluminum closes
Gold disk cover plate node (also known as TEMCOR node), this node places a cover plate, phase at upper lower flange respectively
Link member is respectively connected with cover plate by 8 rustless steel fastening bolts at upper lower flange, and most node connects the six roots of sensation
Rustless steel i shaped cross section rod member, thus form space structure.
But disk cover plate node still suffers from weak point, owing to cover plate is only connected with the rod member edge of a wing by bolt, therefore save
The shear behavior of point is very poor.Due to the existence of bolt hole, either rod member or cover plate all should at the marginal existence of bolt hole
Power concentration phenomenon, and progressively alleviate toward node center from disk cover plate outward flange, therefore structure during node uses
Destroy and be frequently experienced in the position that stress concentration is maximum, i.e. cover plate outer edge generation, weaken the tensile bearing capacity of rod member,
Thus occur in that the phenomenon of " strong component, weak bus ".This phenomenon has run counter to " strong node, the weak component " of engineering design
Requirement, it is therefore desirable to disk cover plate node is improved optimization, to ensure engineering structure stablizing in use
And safety.
Summary of the invention
The present invention solves that technical problem present in known technology provides the widened aluminium alloy in a kind of connecting rod edge of a wing empty
Between structure node, this node can strengthen the tensile strength of existing disk cover plate node, promote its tensile property, to ensure
It meets the engineering design requirement about " strong node, weak component ", it is ensured that the stability of engineering structure and safety.
The present invention solves that technical problem is adopted the technical scheme that present in known technology: a kind of connecting rod edge of a wing
Widened aluminium alloy space structure node, including upper and lower two pieces of disk cover plates and I shape aluminium alloy rod member, this node also wraps
Including center stand column, described center stand column is arranged between upper and lower two pieces of described disk cover plates, upper and lower two pieces of described disk cover plates
Linked together by split bolt with described center stand column；Described I shape aluminium alloy rod member is near described center stand column
End be provided with web protuberance, be provided with rod end loose tongue at described web protuberance near one end of described center stand column；
Radially being provided with the embedded groove coincideing with described web protuberance in described center stand column, the bottom of described embedded groove is
The embedding fourth of the twelve Earthly Branches coincideing with described rod end loose tongue；The flange plate of described I shape aluminium alloy rod member uses with described disk cover plate
High-strength bolt connects, and the flange plate of described I shape aluminium alloy rod member is those widened sections at bolt join domain, adds at flange plate
It is provided with changeover portion between the flange plate of width portion and non-Trapezoidal.
Angle α=120 ° between the flange plate of described changeover portion and described non-Trapezoidal～150 °.
The present invention has the advantage that with good effect: widen the flange plate bolt of I shape aluminium alloy rod member even by employing
Connect district and the structure making I shape aluminium alloy rod member and center stand column use Tenon to be fitting to connection, enhance existing disk cover
The tensile strength of plate node, improves its tensile property, to ensure that it meets engineering design about " strong node, weak component "
Requirement, it is ensured that the stability of engineering structure and safety.
