The distance between plate is less than 40ri, riFor the least radius of gyration of main material angle steel.
Component of the fill plate as reinforcement by connection angle steel and main material angle steel needs the construction according to main material angle steel to be configured,
Reinforcing angle is continuously splicing, and fill plate is then compartment distribution, to the connector for avoiding some inconvenience of main material section from connecting
With bolt etc..
The fill plate has a plural section, and two adjacent sections fill plate is to be mutually perpendicular to, i.e., one section fill plate be laterally positioned in two angle steel it
Between, another is to be longitudinal between two angle steel, and all fill plates are along the uniform interlaced arrangement of main material rod length.
Further include having cruciform gusset plate, include a type long slab and upper and lower two short slab, the cruciform gusset plate, which is located at, to be reinforced
The Varied section junction of angle steel, main material angle steel and reinforcing angle be located at cruciform gusset plate in top side face, main material angle steel
It corresponds to reinforcing angle and is fixedly connected with the long slab of cruciform gusset plate and short slab by bolt respectively.
Supplement of the cruciform gusset plate as fill plate, be mainly used for reinforcing angle Varied section junction connection and
It reinforces, can be used for the reinforcing of main material angle steel Varied section junction, but reinforcing angle Varied section junction need to be with main material angle
Steel Varied section junction is staggered, and avoids concentrating in same level.The connection of fill plate and reinforcing angle and main material angle steel is all only
The connection of one side of angle cleat, cruciform gusset plate and reinforcing angle and main material angle steel is then bilateral to have connection.To reach
The effect reinforced connection and reinforced.
It, can be in conclusion the utility model, which provides, splices angle steel reinforced device outside a kind of old steel tower of transmission line of electricity
Old transmission line of electricity does not have a power failure and is not necessarily under conditions of load removal, utilizes reinforcing angle splicing form twin shaft pair on the outside of former angle steel
Claim star section to combine angle iron component, increase steel tower intensity, have that difficulty of construction is low, cost of investment is few, the construction period is short, knot
The advantages that structure is reasonable.
