Description
Technical field
The present invention relates to a kind of methods for reinforcing Steel Tube Joint, belong to construction engineering technical field, especially a kind of groove profile ring
Oralia moves up the method for reinforcing Steel Tube Joint.
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 structure is extremely important safely.For hollow, thin-walled steel pipe, radial rigidity is much smaller than axial rigidity, the diameter at node
It is much smaller than axial carrying capacity to bearing capacity.It is easiest to deform or break in practice so node weld position is engineering
There is realistic meaning at bad position very much to the Research on Reinforcement Method of node.The reinforcement means of Steel Tube Joint can be divided into inside by construction
Method for strengthening and externally reinforced method.Internal reinforcement is mainly including setting stiffening ring in increase supervisor wall thickness, fill concrete, supervisor or erecting
To several ways such as plates.Internal reinforcement method does not influence node appearance, but due to need to be in interior construction, construction technology
Complexity, difficulty is larger, can only be used in the design phase, it is difficult to be used for the reinforcement of existing structure.The externally reinforced method packet of node
Include welding pasting board, collar extension pasting board, collar extension cornerite pasting board and ribbed stiffener etc..Pasting board method is easy for construction, smaller on constructional appearance influence,
Using relatively broad.But when branch pipe width and little supervisor's different widths, since the space of pasting board is not welded on supervisor surface,
It is not easy to realize that pasting board is reinforced.Although collar extension cornerite pasting board method overcomes the limitation of supervisor's face width, and can be used for existing structure
Or the joint strengthening of newly-built structure, but it is to be improved for the protecting effect of weld seam crack in tension, reinforcing joint still has brittleness to open
The destruction risk split.Therefore, it is necessary to further research and develop, easy for construction, construction is reasonable, protect weld seam and improves adding for ductility of joint
Strong method.
Invention content
Place in order to overcome the above-mentioned deficiencies of the prior art, a kind of groove profile collar extension plate of present invention offer move up reinforcement steel pipe joint
Point method, this method be applicable not only to viability Steel Tube Joint reinforce and it is renovation reinforced, be also applied for design phase steel
The processing of the reinforced node of pipe structure can either improve the static strength of node, and can increase prerupture deformability, prevent
Only there is brittle break with the weld seam at branch pipe in supervisor, and then ensures that there is good antidetonation to prolong for steel construction rigid frame or truss structure
Property performance.
The technical solution adopted by the present invention to solve the technical problems is:Scheme one:A kind of groove profile collar extension plate moves up reinforcement
The method of Steel Tube Joint, including:It is reinforced node host, groove profile collar extension plate, branch pipe, around weld seam, bilateral attachment weld, center
Attachment weld;It is vertically welded with branch pipe in the top surface centre position for being reinforced node host;It is welded on the tube body of branch pipe
Groove profile collar extension plate, groove profile collar extension plate are reinforced node host along supervisor's axis direction or perpendicular to being welded on for axis direction of supervisor
Two sides on or be reinforced on the upper surface of node host, to be formed around weld seam, center attachment weld and bilateral company
Welding seam;It is arranged when groove profile collar extension plate edge is reinforced node host axis direction, and is reinforced node host face width and is difficult to
It, can be by the edge of a wing of groove profile collar extension plate and the sidewall weld for being reinforced node host when ensureing the welding of bilateral attachment weld.
Described be reinforced between node host and branch pipe is reinforced by groove profile collar extension plate, and the height of groove profile collar extension plate should not surpass
It crosses and is reinforced the 1/2 of node host height.
A kind of groove profile collar extension plate moves up the method for reinforcing Steel Tube Joint, when for reinforcing flat in-plane bending node
When, groove profile collar extension plate is along supervisor's axis direction arrangement;When for reinforcing outside plane by curved node, groove profile collar extension plate is perpendicular to master
Tube axis direction is arranged;When for reinforcing axially loaded node, groove profile collar extension plate can be along supervisor's axis or perpendicular to charge shaft
Line is arranged.
The groove profile collar extension plate moves up the method for reinforcing Steel Tube Joint, and it is rectangular steel pipe, the branch to be reinforced node host
Pipe is rectangle or round steel pipe.
When the branch pipe is rectangular steel pipe, groove profile collar extension plate is connected the opened C-shaped aperture mouth in side with branch pipe for U-shaped;The branch
When pipe is round steel pipe, groove profile collar extension plate is connected the opened C-shaped aperture mouth in side with branch pipe for semicircle.
The groove profile collar extension plate moves up the method for reinforcing Steel Tube Joint, when this method is for reinforcing newly-built Steel Tube Joint,
Aperture identical with branch tube shape is first cut out on the web of groove profile collar extension plate, and branch pipe is penetrated to the aperture of groove profile collar extension plate
In, then branch pipe welded directly to the run pipe and the center attachment weld being reinforced between node host, the groove profile collar extension plate edge of a wing is moved to and is added
Strong node host surface contact, last welding groove type ring oralia 2 and the bilateral attachment weld being reinforced between node host and
Around weld seam between groove profile collar extension plate and branch pipe;
When this method is for reinforcing being completed Steel Tube Joint, first by the incision of the web of C-shaped ring oralia and half
Then C-shaped aperture mouth is surrounded branch pipe by the corresponding C-shaped aperture mouth of branch tube shape, the bottom edge of C-shaped ring oralia and will be reinforced node later
It is responsible for surface contact, bilateral attachment weld, the C-shaped ring mouth for finally welding C-shaped ring oralia successively and being reinforced between node host
The groove type plate splicing welding joint between circular weld seam and two C-shaped ring oralias between plate and branch pipe.
Beneficial effects of the present invention:A kind of groove profile collar extension plate, which moves up, to be reinforced the method for Steel Tube Joint and is applicable not only to service
The Steel Tube Joint of period is reinforced and renovation reinforced, and the processing of the reinforced node of design phase steel-tube construction is also applied for;We
The collar extension plate of method is moved up with branch pipe weld seam, can either improve the static strength of node, and can protect supervisor and the weld seam at branch pipe,
Weld seam brittle break is avoided, and then improves the anti-earthquake ductility performance of welding node.
