Key position power transmission is continuous, agent structure form it is rational under the conditions of, convenient welding, operating space are open, welding quality is easy to get
To guarantee, operating efficiency height.
The object of the present invention is achieved like this：A kind of processing method of the close post oblique node of box-type section, is characterized in
Using shutout backstep welding, with reference to the characteristics of box-type section using the anti-method opened of groove, assembling is carried out to component and mutual friendship is welded
The form replaced is processed, and the form of Y shape forged steel pieces is used for internal gusset oblique position, it is ensured that the quality of component is with setting
Performance is counted, its specific processing method is carried out in the steps below：
(1), component blanking
Blanking is carried out to each part plate of the close post oblique node of box-type section according to design requirement, and according to the structure type of component
Leave certain allowance.
（Two）, upper and lower wing plate assembling and welding
On the basis of the lower wing plate of the close post oblique node component of box-type section, the center line of upper each oblique box type rod piece is drawn, according to
Position of center line assembles branch type gusset, and by itself and bottom wing plate weld, then by upper flange assembling on bifurcation type gusset, by it
With upper limb plate weld, each junction node of the branch type gusset uses forged steel pieces, and its groove type is according to the cloth of internal gusset
Office opens up, and is converted into one side pad by double groove.
（Three）, middle and outer side box body assembling and welding
The assembling and welding of gusset and web of the upper and lower wing plate with carrying out middle housing after bifurcation type gusset installation, Ran Houyi
Secondary gusset and endosternum to exterior two outer side box bodies are simultaneously welded, and are carried out after the completion of the hidden weld seam of intra-node all welding
The assembling and welding of two outboard webs, the web groove are padded using one side, and its groove is towards the outside of middle housing；It is described
The outside of its casing of the direction of outboard web groove.
（Four）, eccentric bracket and the assembling and welding of close post grid beam
The assembling of upper and lower eccentric bracket and close post grid beam is carried out after the completion of close post grid beam member bodies erection welding, welding is completed
The processing and fabricating of close post oblique node all terminates afterwards.
The present invention has dimensional accuracy high compared with prior art, and welding quality is good, employ groove it is counter open, complicated junction
The critical technology such as the application of point forged steel pieces and shutout backstep welding, preferably resolves the close post of many rod member box-type sections complicated tiltedly
Node component processing is handed over to there are problems that be particularly suitable for use in large-scale many rod member obliques, and the complicated component shape of internal reinforcing plate structure
Formula, has certain directive function and meaning to the component of close type.

Embodiment
Close post-the frame structure used below with certain skyscraper, its close post carries out oblique in ground low level, forms oblique
Grid is handed over, the close post at oblique position forms close post oblique node, and is aided with the specific processing that eccentric bracket is attached with grid beam
Make, the present invention is further elaborated：
Embodiment 1
Refering to accompanying drawing 1, blanking is carried out to each part plate of the close post oblique node 1 of box-type section according to design requirement, and according to structure
The structure type of part leaves certain allowance.
