Description
Technical Field
The utility model relates to the technical field of power transmission and transformation engineering electric power iron tower application, in particular to a concrete filled steel tube combined iron tower.
Background
In recent years, with the rapid development of social and economic technologies, the rapid growth of social electricity consumption leads to the unprecedented development of power transmission and transformation engineering, in particular to the construction of long-distance extra-high voltage transmission engineering like spring bamboo shoots after rain. The iron tower is an important component of the power transmission project in the power transmission and transformation project, and is a key for supporting wires to ensure power transmission work. The main material used by the traditional transmission engineering iron tower is in an angle steel type, and has the defects of low bearing capacity, large steel consumption and the like, so that the main material cannot meet the construction requirement of a long-distance extra-high voltage transmission engineering, and new requirements are put forward for the design of a transmission iron tower structure. Therefore, an iron tower with high strength, high rigidity, convenient assembly of components and light self weight is urgently needed to meet the engineering requirements.
In summary, the utility model provides a steel tube concrete combined iron tower.
Disclosure of Invention
The utility model aims to provide a steel pipe concrete combined iron tower, which aims to solve the problems that the steel pipe concrete combined structure technology is utilized to realize the requirements of high strength, high rigidity, convenient assembly of components and light dead weight of an electric transmission engineering iron tower in the background technology. The structure type has definite force transmission, excellent performance, simple and convenient construction and good economy. The steel pipe concrete main rod is used as a stress main rod, the cross section of the steel pipe concrete main rod is gradually increased from top to bottom along the vertical length direction, the cross section of the part with smaller stress at the upper part is small, the cross section of the part with larger stress at the lower part is large, the mechanical property is excellent, and the steel pipe concrete main rod is suitable for being applied to long-distance ultra-high voltage conveying engineering and large-span engineering.
The utility model aims at realizing the aim by adopting the technical scheme that the steel tube concrete combined iron tower comprises a connecting gusset plate bolt, corresponding cross arm cross diagonal angle steel of a tower body, a common connecting flange, a steel tube concrete main rod, a bottom flange, foundation bolts and an independent foundation; corresponding body cross arm cross inclined angle steel is connected with the steel pipe concrete main rod through the connecting node plate bolts, a plurality of steel pipe concrete main rods are connected through common connecting flanges, and the steel pipe concrete main rod is connected with the independent foundation through the bottom flange and the foundation bolts.
Further, the cross section of the outer steel tube of the steel tube concrete main rod is round or oval, and the upper section of the steel tube concrete main rod is small and the lower section is large.
Further, the materials of the connecting gusset plate bolts, the corresponding cross arm cross angle steel, the common connecting flange, the steel pipe concrete main rod, the bottom flange and the foundation bolts are common steel or high-strength steel.
Further, the concrete is arranged in the steel pipe concrete main rod, and the independent foundation main body concrete material is common concrete or high-strength concrete.
Further, the independent foundation adopts a prefabricated foundation or a cast-in-situ foundation.
The beneficial effect of above-mentioned scheme is:
1. compared with the conventional power transmission iron tower, the main material of the iron tower body adopts a circular or oval section, and has high bending rigidity and good stability. The steel pipe of the main material of the tower body is filled with concrete, so that the steel amount can be reduced and the dead weight can be lightened under the condition of bearing the same acting force, the construction cost of the iron tower is saved, and the economy is good;
2. the upper section of the steel pipe concrete main rod is small, the lower section is large, and the rigidity is uniformly changed along the length direction. Generally, the top of the iron tower structure is stressed less, and the bottom is stressed more. The rod piece adopted at the position with smaller stress has small rigidity and bearing capacity and good economy. The interaction of the steel pipe and the concrete in the stress process, namely the restraint effect of the steel pipe on the core concrete, ensures that the concrete is under a complex stress state, thereby improving the strength and the ductility of the concrete.
3. The outer steel tube in the steel tube concrete main rod can be used as a built-in concrete pouring template, so that the construction speed is increased.
