Problems solved by technology

In the actual stress process, the angle steel is a two-way eccentric compression member, the stress is extremely complex, and the buckling modes are diverse. Once it occurs, it is very easy to cause the local structural stiffness and strength of the transmission tower to decrease, causing danger.

Abstract

The invention discloses an anti-instability reinforcement device for transmission pole and tower angle steel, which solves the problem that the angle steel of transmission pole and tower may cause structural damage or even overall collapse under the action of strong wind due to its special structural characteristics, which has a serious impact on the normal production order of the country. An anti-instability reinforcing device for the angle steel of a power transmission pole part of the present invention includes: an "L"-shaped external restraint member, an internal support member mainly composed of a semi-circular support pipe, and bolts; bolts for the external restraint member and the internal support member The inner side of the "L"-shaped external restraint member is in contact with the outer side of the angle steel to be restrained; the internal support member is between the two limbs of the angle steel to be restrained, and the outer surface of the semi-circular support tube is tangent to the two perpendicular surfaces of the angle steel to be restrained.

Description

technical field [0001] The invention relates to the field of design anti-instability reinforcement, in particular to an anti-instability reinforcement device for transmission tower angle steel. Background technique [0002] In my country, transmission towers are mainly composed of angle steel, forming a unique space truss structure. Under the action of strong winds, structural damage is likely to occur, and even lead to overall collapse, which has a great impact on my country's normal economic and social order. In addition, the current transmission volume in my country is increasing year by year, and the load of transmission towers has greatly increased. The upgrade of transmission towers often results in an increase in the weight of transmission towers, making the structure of transmission towers more dangerous. [0003] Angle steel transmission towers are simple in construction and convenient in transportation, and are widely used in transmission towers in my country. In...
