Abstract
The utility model aims to provide a connecting structure between iron tower legs and foundation bolts of a transmission line to improve the whole rigidity of a big-span power transmission tower. The aim of the utility model is fulfilled through the following technical means, namely the connecting structure between the iron tower legs and the foundation bolts of the transmission line. The connecting structure is characterized in that: the connection form of the tower legs and the foundation bolts is that the tower legs and the foundation bolts are connected through inner and outer flanges. 48 M72 bolts are adopted and are made from No. 45 steel, wherein the number of inner rings is 20; the number of outer rings is 28; and the distribution proportion of the baring capacity of the inner bolts and the outer bolts is about 0.42:0.58. The connecting structure between the iron tower legs and the foundation bolts of the transmission line has the advantages that: the structure is seasonable; and the whole rigidity of the big-span power transmission tower is improved.
Description
Technical field
The utility model belongs to the iron tower of power transmission line design field, relates in particular to a kind of iron tower of power transmission line tower leg of power transmission line column bar design and the syndeton of stone bolt.
Background technology
Applied analysis by allusion quotation being established tower because still there is the problem of a lot of needs discussions in the use of universal design in the high altitude localities, should simply not applied mechanically as can be known.
At the use in Gansu Province, should on the basis of digesting and assimilating universal design experience, thinking,, carry out replenishing accordingly and revision according to the actual conditions in the Gansu Province.Also we can say and on the basis of universal design, to design again.Just can better realize the life-cycle of state net company proposition and the management thought of intensification.
In iron tower of power transmission line design, the syndeton of iron tower tower leg and stone bolt has varied, but is the key that big overhead crossing engineering designs to the detailing of principles of structural design, dynamic characteristics, wind fluttering factor and the key position of big leap power transmission tower.The particularly detailing of key position by the detailing that this tower leg of the present utility model is connected with stone bolt, is improved big leap power transmission tower integral rigidity.
Summary of the invention
The purpose of this utility model is, goes out the syndeton of a kind of iron tower of power transmission line tower leg and stone bolt, and big leap power transmission tower integral rigidity is improved.
The purpose of this utility model realizes by following technological means:
The syndeton of a kind of iron tower of power transmission line tower leg and lower margin spiral shell rifle bolt is characterized in that: interior outward flange connects the type of attachment of tower leg stone bolt for the tower leg stone bolt adopts.Select 48 M72 bolts for use, No. 45 steel of material, wherein inner ring is 20,28 of outer rings, interior outer bolt bearing capacity distribution ratio is about 0.42: 0.58.
This kind iron tower of power transmission line tower leg and stone bolt syndeton are reasonable, and big leap power transmission tower integral rigidity is improved.
Description of drawings
Below in conjunction with accompanying drawing the utility model is elaborated:
Fig. 1 is tower leg and stone bolt johning knot composition
The specific embodiment
At the use in Gansu Province, should according to the actual conditions in the Gansu Province, carrying out replenishing accordingly and revision on the basis of digesting and assimilating universal design experience, thinking below, is example with a line project, and summary of the invention of the present utility model is described further.
Interior outward flange connects for the tower leg stone bolt adopts for the syndeton of a kind of iron tower of power transmission line tower leg and lower margin spiral shell rifle bolt, the type of attachment of tower leg stone bolt.Select 48 M72 bolts for use, No. 45 steel of material, wherein inner ring is 20,28 of outer rings, interior outer bolt bearing capacity distribution ratio is about 0.42: 0.58.
