Arrange.
It is an advantage of the current invention that: existing end plate secure weld when the present invention assembles, have again three
Fixing welding strengthened by angle strength plate, both ensure that the bonding strength of this node in turn ensure that this node
Physical dimension do not produce skew and deformation, also make welding quality be strengthened；This structure
Due to have employed bolt connect, solve high-altitude construction in interface connecting joint means of spot welds quality not
Easily ensure, affected produced various STRESS VARIATION by the various unfavorable factor such as temperature, wind-force
Variable and the trussmember problem on deformation that causes；The connected mode of the present invention is by from high missing solder
Connecing in succession and change into workshop and be welded to connect, building-site uses high-strength bolt to connect after width connects
After, construction method of installation step substantially reduces, and can save great amount of cost, reduce the engineering time,
Reduce security risk and can be by components (such as roofing chord member) such as cross-brace truss
Link together well.
The present invention sets up and connects end plate and can make full use of the dull material (dull plate) in workshop and enter
Row cutting, setting-out, drilling, thousand people's one sides can perform a standard by plane projection setting-out,
Welding quality, node apparatus component product quality the most guaranteed, it is simple to standardization, in batches
Change, batch production, industrialization, standardization pipelining, efficiency improves, and produces battalion
Fortune cost reduces；Current truss construction Assembling precision can not only be changed be difficult to ensure and frame
If safe construction operating platform expense expect, takes a lot of work, time-consuming, joint weld welding quality is difficult to guarantor
Card, security risk is big, and slowly, equipment investment amount is big waits cost to rise violently problem in construction, and
Equipment investment can also be improved few, artificial less investment, construction and installation speed is fast, component quality and
Construction quality is all readily obtained and is satisfied with phenomenon, makes each combined member organically combine more
Perfect, reasonable, fine.
