The utility model relates to iron fitting technical fields, particularly relate to a kind of steel tower iron fitting, including upper plywood, lower plywood, bolt, the surrounding of the upper plywood and lower plywood is respectively equipped with the first screw hole, among the upper plywood bottom and lower plywood top center is all provided with fluted along its longitudinal direction, bolt is inserted at the upper plywood and lower the plywood both ends before being fixed with fastening bolt, the bolt includes end, second screw hole, parcel, the parcel is U-shaped, the parcel upper end is equipped with end inward, the end is equipped with the second screw hole, the fastening bolt first passes through the second screw hole of bolt end, the first screw hole for being each passed through plywood and lower plywood again carries out screwing tight fixation.Compared with prior art, the utility model has the beneficial effects that stability is good the utility model discloses a kind of steel tower iron fitting, support strength is high.
Description
Technical field
The utility model relates to iron fitting technical fields, particularly relate to a kind of steel tower iron fitting.
Background technique
Electric power tower is generally divided into shape: wine glass-shaped, cathead, upper font, dry font and five kinds of barrel shape, by use
Way point has: anchor support, tangent tower, angle tower, transposition tower, terminal tower and crossover tower etc., they are structurally characterized in that various towers
Belonging to space truss structure, rod piece is mainly made of single equal leg angle or combination angle steel, and connection uses rough bolt between rod piece,
By bolt by Shear connection, entire tower is made of angle steel, junction steel plate and bolt, is collectively referred to as iron fitting.
Iron fitting is several insulator chains of connection or multiple stress branches is assembled into whole plate shape connection gold utensil.It is existing
Iron fitting in technology will appear crackle after some certain interval of time in the application of transmission line of electricity, find crackle through analysis
Appearance is because the self weight of conducting wire produces biggish shearing force to iron fitting, and stress concentrates at screw hole, to make iron fitting
Discontinuity cracks.
Utility model content
The utility model discloses a kind of steel tower iron fittings, and stability is good, and support strength is high.
The utility model is achieved through the following technical solutions:
The surrounding of a kind of steel tower iron fitting, including upper plywood, lower plywood, bolt, the upper plywood and lower plywood is set respectively
There is the first screw hole, the upper plywood bottom centre and lower plywood top center are all provided with fluted, the upper conjunction along its longitudinal direction
Bolt is inserted at plate and lower the plywood both ends before being fixed with fastening bolt, and the bolt includes end, the second screw hole, parcel, institute
It is U-shaped to state parcel, the parcel upper end is equipped with end inward, and the end is equipped with the second screw hole, the fastening bolt
The second screw hole of bolt end is first passed through, then is each passed through plywood and the first screw hole of lower plywood carries out screwing tight fixation.
Preferably, the groove uses semi-circular structure.
Preferably, the upper plywood, lower plywood and bolt are all made of Q235 or Q345 material.
Compared with prior art, the utility model has the beneficial effects that on the utility model plywood and lower plywood long side
Cable is worn on direction, so that iron fitting stress becomes longitudinal pulling force from shearing force, avoids crackle caused by concentrating because of stress,
The stability of iron fitting is improved, support strength is high.
Detailed description of the invention

Fig. 2 is the structural schematic diagram of the utility model；
Fig. 3 is the structural schematic diagram of the utility model bolt.
In figure: 1, fastening bolt；2, upper plywood；3, lower plywood；4, the first screw hole；5, bolt；51, end；52, the second spiral shell
Hole；53, parcel；6, groove.
Specific embodiment
The present invention will be further described with reference to the accompanying drawing:
The surrounding of a kind of steel tower iron fitting, including upper plywood 2, lower plywood 3, bolt 5, the upper plywood 2 and lower plywood 3 point
Not She You the first screw hole 4, among upper 2 bottom of plywood and lower 3 top center of plywood is all provided with fluted 6 along its longitudinal direction,
The upper plywood 2 and lower plywood 3 are being inserted into bolt 5 with the fixed preceding both ends of fastening bolt 1, and the bolt 5 includes end 51, second
Screw hole 52, parcel 53, the parcel 53 is U-shaped, and 53 upper end of parcel is equipped with end 51, the end 51 inward
It is equipped with the second screw hole 52, the fastening bolt 1 first passes through the second screw hole 52 of 5 end 51 of bolt, then is each passed through conjunction
First screw hole 4 of plate 2 and lower plywood 3 carries out screwing tight fixation.
The groove 6 uses semi-circular structure.
The upper plywood 2, lower plywood 3 and bolt 5 are all made of Q235 or Q345 material.
Cable is worn in the longitudinal direction of plywood and lower plywood on the utility model, so that iron fitting stress is become by shearing force
For longitudinal pulling force, crackle caused by concentrating because of stress is avoided, improves the stability of iron fitting, support strength is high.
The above only expresses the embodiments of the present invention, and the description thereof is more specific and detailed, but can not be because
This and be interpreted as that a limitation on the scope of the patent of the present invention, within the spirit and principle of the utility model, made
What modification, equivalent replacement, improvement etc., should be included within the scope of protection of this utility model, the guarantor of the utility model patent
Shield range should be determined by the appended claims.
