Abstract
H-type rod piece part reduced beam section plate-type node, belongs to connecting node technical field.Including upper and lower two gusset plates, multiple fasteners, more local reduced beam sections 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 since the H-type rod piece part edge of a wing outside to gusset plate weakens, and absorbs energy.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 present invention relates to one of latticed shell structure H-type rod piece part reduced beam section plate-type nodes.Wherein reticulated shell can be with
It is sphere net case, cylindrical reticulated shell etc., belongs 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 present invention is all
Component can be processed in advance in factory, carry out at the scene later assembled, and meet that country advocated is environmentally protective, energetically
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.
Technical scheme is as follows:
This node includes that upper and lower two gusset plates (1), multiple fasteners (such as bolt) (2) and the more local edges of a wing are cut
Weak H-type rod piece (3)；H-type rod piece (3) end edge of a wing passes through multiple fasteners (2) and upper gusset plate (1-1) and lower node respectively
Plate (1-2) is fixed together；
The reduced beam section region of rod piece is located on the outside of gusset plate (1), and weakening area can include H-type rod piece top flange simultaneously
(3-1) and lower flange (3-2) or any unilateral edge of a wing, weakening area edge of a wing contour line can be for circular arcs or by the other of arc transition
Shape.
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, are had on the gusset plate lateral area edge of a wing by contour line for circular arc or by the other of arc transition
The weakening area that the groove of shape is constituted, weakening area number of recesses can be one or more；Weakening area depth of groove (a) is
The 1/5-1/4 of flange width, single groove development length (b) are 1.0-2.0 times of flange width, and weakening area recess edge arrives
Upper gusset plate (1-1) or lower node plate (1-2) outermost bolt hole distance (c) are 1.0-2.0 times of flange width.Rod piece number
It can be changed according to actual needs.
This node makes such gusset-type joint exist due to weakening to the local edge of a wing of the H-type rod piece (3) of gusset plate (1) outside
The weakened part for bearing rod piece when low cycling loads generates moderate finite deformation, and absorbs energy.Relative to general gusset-type joint,
The present invention guarantees that node region does not destroy first, improves node in geological process while improving node energy dissipation capacity
Under security performance.
