The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
It is example that the present embodiment be take transmission line of electricity emergent repairing tower base, and as shown in Figure 2 to Figure 3, the transmission line of electricity emergent repairing tower base point that the embodiment of the present invention provides comprises: flap 1, basis 2, pivot pin 3, tower body 4, bolt 5.Basic 2 levels are arranged on to ground, fixing hole by four jiaos of basic 2 bottom surfaces is fixed, after being docked with the pin-and-hole of basic 2 end faces, insert flap 1 pivot pin 3, open flap 1, make flap 1 and the angle of basic 2 end faces remain on 90 °, after being docked with the pedestal of flap 1, the emergent repairing tower tower body 4 of horizontal positioned is bolted to connection, establish emergent repairing tower tower body 4, flap 1 rotate around pivot pin 3 until fit with basic 2 end faces, now flap 1 are 0 ° with the angle of basic 2 end faces, erection bolt 5 fastening in the corresponding through hole of flap 1 and basic 2 end faces, so far emergent repairing tower tower body 4 is established on base.
Emergent repairing tower base folding paper syndeton provided by the invention is with the difference that tradition is articulated and connected, folding paper structure meet establish and the functional requirement of the tower body that fell in, greatly simplified the form of structure of parts, and, reduce the quantity of parts, improved the unfailing performance of structure.On the other hand, after emergent repairing tower has been established, the lower end the way of restraint of whole tower structure is different, traditional be articulated and connected to be similar to be articulated and connected, and folding paper syndeton provided by the invention is fixed by connecting bolt, for fixed constraint connects, for the feature of long fine texture pressure-bearing, folding paper syndeton provided by the invention is more conducive to improve integrally-built pressure-bearing critical load.
Application Euler's formula represents the critical load of elongated compressed structure:
In formula, π is constant, and E is relevant to material properties, and I is the geometric attribute relevant to tower body cross section, the height that l is tower, and μ is the length factor relevant to end restraint condition.
Under material and the measure-alike condition of emergent repairing tower, emergent repairing tower top is fixed by bracing wire, belongs to hinged.Traditional emergent repairing tower tower body lower hinge bearing is hinged, μ value 1.0; And folding paper of the present invention connects, emergent repairing tower tower body bottom and base are clamped, μ value 0.7; Hence one can see that, and the traditional base of critical bearing capacity ratio of the emergent repairing tower base that the embodiment of the present invention provides has improved about 2 times.
Wherein, preparation submount material be by weight percentage, Si :≤0.38%, Cu :≤0.12%, Mg:3.2～4.1%, Zn :≤0.27%, Mn:0.18～0.66%, Ti :≤0.14%, Cr:0.05～0.23%, Fe:0.000～0.400%, surplus is Al.
In the present embodiment, preparing submount material is by weight percentage, Si:0.35%, and Cu:0.10%, Mg:3.8%, Zn:0.22%, Mn:0.47%, Ti:0.08%, Cr:0.15%, Fe:0.250%, surplus is Al.Adopt the base of above-mentioned material durable, load-carrying properties have improved 3.8% than common product, and also greatly extend application life.
