Description
Technical field
This utility model relates to a kind of method strengthening Steel Tube Joint, belongs to construction engineering technical field, especially a kind of groove
The reinforcement Steel Tube Joint moved on type collar extension plate.
Background technology
Steel-tube construction is widely used in building, bridge, pylon and offshore platform structure, reliable ultimate bearing capacity of joints pair
Ensure that structural safety is extremely important.For hollow, the steel pipe of thin-walled, its radial rigidity is much smaller than axial rigidity, the footpath at node
To bearing capacity much smaller than axial carrying capacity.So node weld position is to be easiest in engineering reality deform or broken
Bad position, the Research on Reinforcement Method to node, there is very much realistic meaning.The reinforcement means of Steel Tube Joint can be divided into inside by structure
Method for strengthening and externally reinforced method.Internal reinforcement sets stiffening ring or perpendicular in mainly including increasing supervisor wall thickness, fill concrete, supervisor
To several ways such as plates.Internal reinforcement method does not affect node appearance, but due to need to be in interior construction, construction technology
Complexity, difficulty is relatively big, can only use in the design phase, it is difficult to for the reinforcement of existing structure.The externally reinforced method bag of node
Include welding pasting board, collar extension pasting board, collar extension cornerite pasting board and ribbed stiffener etc..Pasting board method easy construction, less on constructional appearance impact,
Apply relatively broad.But when arm width is little with supervisor's different widths, owing to the space of pasting board is not welded on supervisor surface,
It is difficult to realize pasting board reinforce.Although collar extension cornerite pasting board method overcomes the restriction of supervisor's face width, and can be used for existing structure
Or the joint strengthening of newly-built structure, but the protected effect for weld seam crack in tension is to be improved, and reinforcing joint still has fragility to open
The destruction risk split.Accordingly, it would be desirable to research and develop further easy construction, structure rationally, protect weld seam and improve adding of ductility of joint
Strong method.
Summary of the invention
In place of overcoming above-mentioned the deficiencies in the prior art, this utility model provides the reinforcement steel moved on a kind of grooved collar extension plate
Pipe node, this node is applicable not only to the Steel Tube Joint of viability and reinforces and renovation reinforced, is also applied for design phase steel pipe
The processing of the reinforced node of structure, can either improve the static strength of node, can increase again prerupture deformability, prevent
There is brittle break in weld seam at supervisor and arm, and then ensures that steel construction rigid frame or truss structure have good anti-earthquake ductility
Performance.
This utility model solves its technical problem and be the technical scheme is that the reinforcement steel moved on a kind of grooved collar extension plate
Pipe node, including: being reinforced node host, grooved collar extension plate, arm, around weld seam, bilateral attachment weld, center connects weldering
Seam；It is vertically welded with arm in the end face centre position being reinforced node host；Grooved ring it is welded with on the body of arm
Oralia, grooved collar extension plate along supervisor axis direction or be perpendicular to be responsible for axis direction be welded on the both sides being reinforced node host
On limit or be reinforced on the upper surface of node host, thus formed around weld seam, center attachment weld and bilateral attachment weld；
When grooved collar extension plate is arranged along being reinforced node host axis direction, and it is reinforced node host face width and is difficult to ensure that bilateral
During the welding of attachment weld, can be by the edge of a wing of grooved collar extension plate and the sidewall weld being reinforced node host.
Described being reinforced between node host and arm is strengthened by grooved collar extension plate, and the height of grooved collar extension plate should not surpass
Cross and be reinforced the 1/2 of node host height.
The reinforcement Steel Tube Joint moved on described a kind of grooved collar extension plate, when being used for strengthening flat in-plane bending node, groove
Type collar extension plate is arranged along supervisor's axis direction；When being used for strengthening plane outward by curved node, grooved collar extension plate is perpendicular to charge shaft
Line direction is arranged；When being used for strengthening axially loaded node, grooved collar extension plate or can be perpendicular to be responsible for axis cloth along being responsible for axis
Put.
The reinforcement Steel Tube Joint moved on described grooved collar extension plate, being reinforced node host is rectangular steel pipe, and described arm is
Rectangle or round steel pipe.
When described arm is rectangular steel pipe, grooved collar extension plate side the opened C-shaped aperture mouth that is connected with arm is U-shaped；Described
When pipe is for round steel pipe, grooved collar extension plate is connected side opened C-shaped aperture mouth for semicircle with arm.
Use operational approach: when this method is used for strengthening newly-built Steel Tube Joint, first cut on the web of grooved collar extension plate
Go out the aperture identical with tube shape, and arm penetrated in the aperture of grooved collar extension plate, then branch pipe welded directly to the run pipe be reinforced joint
Center attachment weld between some supervisor, moves to the grooved collar extension plate edge of a wing and is reinforced node host surface and contacts, finally weld
Around weldering between access slot type collar extension plate 2 and the bilateral attachment weld being reinforced between node host and grooved collar extension plate and arm
Seam；
When this method is used for strengthening built Steel Tube Joint, first the web of C-shaped ring oralia is cut and 1/2nd
The C-shaped aperture mouth that tube shape is corresponding, then surrounds arm by C-shaped aperture mouth, afterwards by the base of C-shaped ring oralia be reinforced node
The contact of supervisor surface, the most successively welding C-shaped ring oralia and the bilateral attachment weld being reinforced between node host, C-shaped ring mouth
The groove type plate splicing welding joint between cincture weld seam and two C-shaped ring oralias between plate and arm.
The beneficial effects of the utility model: the reinforcement Steel Tube Joint moved on this kind of grooved collar extension plate is applicable not only to service
The Steel Tube Joint of period is reinforced and renovation reinforced, is also applied for the processing of the reinforced node of design phase steel-tube construction；We
Move on the collar extension plate of method and arm weld seam, the static strength of node can either be improved, the weld seam at supervisor and arm can be protected again,
Avoid weld seam brittle break, and then improve the anti-earthquake ductility performance of welding node.
