Abstract
H-type rod piece part holes in soffit plate-type node, belongs to connecting node technical field.Including upper and lower two gusset plates, multiple fasteners, more local holes in soffit H-type rod piece.The H-type rod piece end edge of a wing passes through multiple fasteners respectively and is fixed together with upper gusset plate and lower node plate.This node makes the weakened part of such gusset-type joint rod piece when bearing low cycling loads generate moderate finite deformation, and absorb energy due to carrying out the weakening that punches to H-type rod piece part web.Relative to general gusset-type joint, this node guarantees that node region does not destroy first, improves security performance of the node under geological process while improving node energy dissipation capacity.
Description
Technical field
The utility model relates to one of latticed shell structure H-type rod piece part holes in soffit plate-type nodes.Wherein reticulated shell
It can be sphere net case, cylindrical reticulated shell etc., belong to connecting node technical field.
Background technique
Nowadays China largely promotes equipment and builds with formula, this is because relative to traditional form of construction work, assembled
Have many advantages, such as the shortening construction period, reduces carrying capacity of environment, reduces the wasting of resources, improving construction quality, and the utility model
All components can be processed in advance in factory, carry out at the scene later it is assembled, meet that country advocated it is environmentally protective,
Greatly develop the theory of assembled architecture.
With welding and the development of extrusion technique, the form of rod piece is also diversified, including tubulose, H-type, box.Due to H
Type rod piece anti-bending strength, load performance is good, saves material, and the edge of a wing of H-type rod piece with web area is larger that bolt is facilitated to connect
It connects, so more and more engineerings begin to use H-type rod piece.
Aluminium alloy due to its lightweight, it is corrosion-resistant the advantages that gradually receive the favor of engineers.In large span spatial structure
Among, aluminium alloy its density for steel is only the one third of steel, can be greatly lowered under identical span
The influence being self-possessed to structure reduces influence of the earthquake to structure, while also in that the span of this feature aluminium alloy structure can
With more big.Aluminum alloy materials aoxidize in air can form fine and close oxidation film, the knot for natatorium, under marine climate
For structure, aluminium alloy can reduce the maintenance cost in later period with the extending structure service life.
It is the gusset-type joint researched and developed by Tai Muke company, the U.S. mostly used in the aluminium alloy sphere net case in China, and
There is following deficiency in this node:
Since the edge of a wing is bolted and bolt number is more with upper and lower gusset plate, significantly weaken in nodes domains
The rod piece edge of a wing so that destruction of a node mode be usually in H-type rod node domain the edge of a wing or gusset plate be broken along bolt hole.On ground
Under shake effect, since the node type of attachment has biggish rigidity, node energy dissipation capacity is poor, and final position of destroying still is being saved
In point domain.
Summary of the invention
Gusset-type joint is improved herein in order to solve the above deficiency.
The technical solution of the utility model is as follows:
This node includes the H-type rod piece of upper and lower two gusset plates, multiple fasteners (2) and more local holes in soffit
(3)；H-type rod piece (3) end edge of a wing passes through multiple fasteners (2) and upper gusset plate (1-1) respectively and lower node plate (1-2) is fixed
Together；
The holes in soffit region of rod piece is located on the outside of gusset plate (1) or inside, and the quantity that punches can be one or more, punches
Shape can be round, ellipse or rectangle etc..
The gusset plate up and down is also possible to cambered plate it is characterized in that: shape can be plate；Material can be aluminium conjunction
Gold is also possible to steel.
Multiple fasteners can be stainless steel bolt, can be high-strength spiral shell it is characterized in that: can be plain bolt
Bolt is also possible to rivet；Material can be aluminium alloy, be also possible to steel.
The plurality of rods part is also possible to extrusion forming it is characterized in that: material can be the steel of hot rolling or welding
Aluminum alloy materials, shape are H-type, there is one or more round, ellipses or rectangle on the outside of gusset plate or on inside region web
Hole constitute weakening area, when punch number be 1 when, circular hole diameter be web height 1/3-1/2, ellipse
The long and short axis of hole is the 1/3-1/2 of web height, the long side of rectangle hole, the 1/3-1/2 that broadside is web height, hole type
The heart is to rod end apart from 1.0-2.0 times for web height.
This node keeps such gusset-type joint past in receiving low week due to carrying out the weakening that punches to the local web of H-type rod piece (3)
The weakened part of rod piece generates moderate finite deformation when multiple load, and absorbs energy.Relative to general gusset-type joint, the utility model
Guarantee that node region does not destroy first, improves peace of the node under geological process while improving node energy dissipation capacity
Full performance.
