Description
Technical field
The present invention relates to positioning angle steel, the construction for iron tower of power transmission line.
Background technology
In the construction of grid power transmission steel tower, leading role's steel of steel tower tower leg must in basis high accuracy positioning, including it is front and rear,
The steel tower root of left and right directions opens size, and the discrepancy in elevation between each tower leg, leading role's steel is in the gradient on direction around, iron tower main material
The gradient it is consistent etc., it is necessary to it is accurate.To reduce material usage, construction cost, main stub-angle-inserted foundation construction are reduced
Method can be used and is suspended in basic stand column, and leading role's steel lower end is not joined directly together with basis.But due to hanging type leading role's steel
It is suspended in inside taper pile shuttering, does not possess the condition of horizontal direction fixation and the condition of support, the gradient of inserted angle steel and position
It is difficult control to put.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of variable cross-section auxiliary positioning angle steel, facilitates position control, saves
Construction material.
In order to solve the above technical problems, the technical solution used in the present invention is：
Variable cross-section auxiliary positioning angle steel, including be arranged on the support angle steel of bottom, be fixedly connected with support angle steel top
Leading role's steel that angle cleat, bottom are fixedly connected with angle cleat, the lower inside of angle cleat and the angle on support angle steel top
Steel back is connected, and the angle steel back of the body on angle cleat top is connected with the inner side of leading role's steel bottom；Some through holes are set on leading role's steel；
Support angle steel bottom sets location-plate.
Further improvement of the present invention is：Support angle steel top is with being connected with the angle steel back of the body of angle cleat connecting portion
The fillet that the inner shape of angle steel fits；The angle steel of angle cleat and leading role's steel connecting portion is carried on the back
The fillet to fit.
Further improvement of the present invention is：Angle cleat top sets the connecting hole corresponding with the through hole of leading role's steel,
The through hole of leading role's steel and the connecting hole of angle cleat are connected by fixing bolt.
Further improvement of the present invention is：Two leg of angle backs of leading role's steel set one section and leading role's steel direction respectively
Vertical angle steel section, the length of angle steel section are identical with the leg of angle width of leading role's steel.
Further improvement of the present invention is：Angle steel section level height on two legs of angle of leading role's steel is different.
Further improvement of the present invention is：Each angle steel section is connected with leading role's steel by 2 ~ 4 fixing bolts.
Further improvement of the present invention is：The location-plate is threaded the square plate in hole, one group of location-plate for middle part
Diagonally it is arranged respectively to chamfering.
Because using above-mentioned technical proposal, beneficial effect caused by the present invention is：
A kind of variable cross-section auxiliary positioning angle steel of the present invention, facilitate position control, save construction material.
The support angle steel of the present invention can be that main angle steel positions, and provide supporting condition for main angle steel, make to be suspended in batter post mould
The positioning that intralamellar part can also be stablized.Support angle steel model is smaller simultaneously, saves construction material, saves the cost of engineering.
The angle cleat of the present invention can provide condition for support angle steel and main Bolted angle connection, pass through the position of fixing bolt
Adjust the location status of leading role's steel.
Bolt of the location-plate of the present invention with the basis of coordinates, according to the angle of the angle-determining of the bolt present invention, so that
The gradient of leading role's steel is determined, the position being arranged on by location-plate on bolt determines the height of leading role's steel, thus can accurately control
The position of leading role's steel processed.

Embodiment
The present invention is described in further details below in conjunction with the accompanying drawings：
Variable cross-section auxiliary positioning angle steel, including support angle steel 3, angle cleat 2 and leading role's steel 1, angle cleat 2 use L100
× 10 × 300 angle steel, support angle steel 3 are the small angle steel in L70 × 8；The top of support angle steel 3 welds together with angle cleat 2, support
The angle steel back of the body on the top of angle steel 3 carries out back-off processing, is shaped to the inner side identical fillet with angle cleat 2, support angle steel 3
The angle steel back of the body on top is bonded with the inner side of angle cleat 2 to be welded together.
The top of angle cleat 2 is bolted with the bottom of leading role's steel 1, and two rows are set on each leg of angle of leading role's steel 1
Through hole 1-2, the top of angle cleat 2 set the connecting hole corresponding with the through hole 1-2 of the bottom of leading role's steel 1, angle cleat 2 and leading role
Steel 1 is fixed together by fixing bolt 4 through through hole 1-2 and connecting hole.The angle steel back of the body on the top of angle cleat 2 is carried out at back-off
Reason, is shaped to the inner shape identical fillet with leading role's steel 1.
The back of two legs of angle of leading role's steel 1 sets angle steel section 1-1 respectively, facilitate in tower material the connection of other assemblies and
Positioning, angle steel section 1-1 length is identical with the leg of angle width of leading role's steel 1, and angle steel section 1-1 is vertically arranged with leading role's steel 1.Angle steel
The through hole corresponding with the through hole 1-2 of leading role's steel 1 is set on section 1-1, angle steel section 1-1 through hole leads to the through hole 1-2 of leading role's steel 1
Fixing bolt 4 is crossed to connect.Angle steel section 1-1 adjusts angle steel section 1-1 position by connecting the through hole 1-2 of the diverse location of leading role's steel 1
Put.
When angle steel section 1-1 is arranged on leading role 1 bottom of steel, fixing bolt 4 can connect leading role's steel 1, angle cleat 2
With angle steel section 1-1, to save the dosage of fixing bolt 4.
The bottom of support angle steel 3 sets location-plate 3-1, location-plate 3-1 to be threaded the square plate in hole, location-plate 3- for middle part
