Abstract
The utility model relates to a prestressed angle steel tower which comprises angle steel forming a tower body (1) on which a ladder (2) and a working platform (14) are arranged. The utility model is characterized in that the cross section of the tower body (1) is a regular triangle, and tower feet (11) at the lower end of the tower body (1) are fixed on a ground in triangular distribution. The tower body of the utility model has the triangular cross section, and a triangular structure has good stability, so the utility model has better functions of preventing wind and shock firmly. In addition, the utility model has the advantages of simple structure, easy manufacture in a factory and short construction periodicity, and can save steel from 20 percents to 25 percents and occupied area from 40 percents to 50 percents so as to reduce the manufacturing cost of the steel tower and to improve the utilization rate of field, compared with a conventional tower having four corners.
Description
Technical field
The utility model relates to a kind of prestressing force angle steel tower of being made up of angle steel.
Background technology
Existing communication class iron tower has prestressing force quadrangle angle steel tower, prestressing force single-pipe tower and prestressing force three pipe towers.And its span of the column foot of tetragonal angle steel tower normally body of the tower 1/5, steel quantity consumption is very big, complex structure, transportation difficulty, lifting construction and installation difficulty is big and the construction period is long; Though single-pipe tower improves a lot making and install, the steel pipe because no heavy caliber is finalized the design, but to adopt large-scale plate bending rolls that roll of steel plate is made pipe, manufacture difficulty is bigger, is difficult to popularization and application; Though three pipe iron towers have certain improvement, spool, watt connection of its plurality of sections of steel pipes, technological requirement height, difficulty of processing is big, and three groups of steel tube body are with after crossbeam is fixedlyed connected, and volume is very big, transportation is trouble and freight height very, so above-mentioned structure all awaits improving.
Summary of the invention
Technical problem to be solved in the utility model be provide at above-mentioned prior art present situation a kind of reasonable in design, cost is low, sound construction, easy for installation and prestressing force angle steel tower that floor space is few.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this prestressing force angle steel tower, include the angle steel of forming body of the tower, body of the tower is provided with cat ladder and working platform, it is characterized in that its cross section of described body of the tower is a triangle, and the column foot of body of the tower lower end distribution triangular in shape and being fixed on the ground.
Above-mentioned column foot is separately positioned on leg-of-mutton three vertex positions; And described triangle is an equilateral triangle.
Three mobile jibs of above-mentioned body of the tower adopt big angle steel, and promptly vertically being distributed in the triangular apex position of body of the tower, and cross bar on the body of the tower and pull bar adopt little angle steel, and interconnect by bolt and junction plate respectively between the angle steel.
Above-mentioned cat ladder and working platform can be arranged at body of the tower inside respectively, and described cat ladder can select to be fixed in the middle part of body of the tower.
As improvement, described column foot can be selected to be fixed on the pedestal on ground, and this pedestal may be selected to be the cement steel pour mass, and column foot can be preferably with being connected of pedestal, and column foot fixes for welding or bolt ground connection and pedestal.
Compared with prior art, the utility model is a triangle because of adopting its cross section of described body of the tower, and the lower end of body of the tower is equilateral triangle and distributes and be fixed on the ground.Because of triangular structure has good stable, and that the structure of equilateral triangle has body of the tower is more well-balanced, the higher characteristic of the littler and mutual connective stability of floor space, so can be better, play windproof and shockproof effect more firmly, thereby prolong the application life of iron tower effectively, to compare the utility model not only simple in structure with conventional four turrets, factory process is convenient, install easily, short construction period, and can save steel 20-25%, saving covers an area of 40-50%, thereby has reduced the cost of manufacture and the utilization rate that has improved the soil of iron tower significantly; And cat ladder of the present utility model and working platform not only make the body of the tower appearance more attractive in appearance for being arranged at body of the tower inside respectively, and staff's operation is also with safer and more convenient.
