Description
Technical field
The utility model relates to the main equipment structure of angle steel tower of power transmission line after a kind of reinforcing.
Background technology
Transmission angle steel tower is current high voltage overhead power transmission application member the most widely, but because the old angle steel tower of part pattern exists design defect, existence bears that wind carries and the shortcoming of anti-ice cover ability, occurs under arms the accident of falling tower in process, need carry out consolidation process.Taking ZGU2(7727) 110 kilovolts of double loop straight line towers are example, this tower is widely used in line design before 2005.After within 2005, national grid Typical Design of Transmission Lines within Voltage is published, this tower has not been made recommendation.Due to the tower material size design remaining deficiency of ZGU2 tower, under extreme weather conditions, easily cause steel tower to topple, in actual moving process, this tower repeatedly deforms and the accident of falling tower, brings serious potential safety hazard to power grid security, therefore needs to carry out consolidation process.The main material of tower body is weak link stressed in transmission angle steel tower structure, improve the supporting capacity of angle steel tower, must reinforce main material.Existing method be in the side of the main material of angle steel by junction plate and a bolt new same specification angle steel in parallel, increase the sectional area of whole main material member, thereby reach the object that improves angle steel tower main material carrying.
But there is following shortcoming in this kind of method: 1. due to the angle iron component that has adopted bolt fixedly to newly increase, therefore need on the main material of former angle steel, open a large amount of bolts hole, and not only complex process, and also there is potential safety hazard in perforate process and the effect that weakens brought thereof.2. before reinforcing, former angle iron component is a uniaxial force member, and after employing bolt angle iron component in parallel, new combined member has formed the bending component of eccentric force, and stress hysteresis is serious, causes bearing capacity to improve degree lower.3. adopt the method for bolt angle steel in parallel need use a large amount of junction plates and bolt, cost is higher.Scantling after bolt angle steel in parallel obviously increase, complex contour, affect tower material outward appearance, and angle steel in parallel is positioned at outside former angle steel, increased and stepped on tower and upkeep operation difficulty to maintainer.
Utility model content
For addressing the above problem, the utility model proposes the main equipment structure of angle steel tower of power transmission line after a kind of reinforcing, adopt the method for welded lap to complete the reinforcing of iron tower main material position, avoided adopting the complicated procedures of forming of bolt angle steel in parallel, and this kind of ruggedized construction good looking appearance, save material.
To achieve these goals, the utility model adopts following technical scheme.
The main equipment structure of angle steel tower of power transmission line after a kind of reinforcing, comprise main material, diagonal brace, diagonal brace is bolted on main material, on main material, be welded with reinforcing angle I, reinforcing angle I and corresponding position, diagonal brace position are provided with skewed slot, its angle, size match with diagonal brace, on reinforcing angle I, be welded with a reinforcing angle II, the corresponding position, skewed slot position of reinforcing angle II and reinforcing angle I is provided with skewed slot, gap between reinforcing angle I and main material, the weather-resistant glue of sealing use is filled up at the gap place between reinforcing angle I, reinforcing angle II; Reinforcing angle I, reinforcing angle II and main material reinforcing area surface spraying have zinc content to be greater than the corrosion-resistant finishes that 90% cold galvanizing spraying forms.
Described reinforcing angle I is than the wide 0-8mm of length on tower leg main material angle steel limit, and selected reinforcing angle I is than the large 0-5mm of thickness on tower leg main material angle steel limit.
Described reinforcing angle II than the length of reinforcing angle I wide-5mm-8mm, selected reinforcing angle II is than the large 0-5mm of thickness on tower leg main material angle steel limit, length is 200mm-500mm.
The beneficial effects of the utility model:
1. this structure directly pastes angle steel in former angle steel inner side, has avoided a large amount of bolt hole perforate work, and technique is simple, safe;
2. because reinforcing is interior sticking structure with new angle iron component, approach the state of axial compression of former member, can significantly improve the bearing capacity of former member;
3. save a large amount of junction plates and bolt;
4. main material good looking appearance after reinforcing, has no adverse effects to upkeep operation.
