Abstract

The utility model provides a special section bar and a tower or a steel tower which is constituted by using the special section bar, and the purpose is to solve the problem of unreasonable structure in prior steel towers. The special section bar made of thin-wall section bar by cold bending is composed of two symmetrical thin planes which form an angle. The steel tower comprises three main columns and a plurality of cross bars, and the cross bars and the main columns are connected, and the main columns which are the special section bars are positioned at the three corners of an analogous equilateral triangle. By adopting the cold bending special section bar, the tower can be directly connected and mounted by using fasteners, and the bending resistant performance and the stability of the tower can be improved. Compared with square or rectangular towers, the single material amount of the tower can be decreased by 20 percent, and the tower is easy to be transported and mounted with small ground occupying.

Description

Special section bar and tower thereof

Technical field

The utility model relates to a kind of special section bar and is tower or the iron tower that principal post constituted by this special section bar.Be mainly used in communication, the power system.

Background technology

In existing communication or the power system, the iron tower used as electric power system adopts mainly that traditional to pass through an angle of 90 degrees steel that hot rolling forms be principal post, utilizes cross bar, brace again or/and auxiliary rod etc. are formed by connecting by frame modes such as welding or bolt connections.This tower is owing to adopt an angle of 90 degrees steel as principal post, and its pyramidal structure that assembles (plane structure) is square or rectangle, and its form of structure is single and have following defective: 1, structure is complicated; As the tower of square or rectangular configuration, its principal post (pillar or column) quantitatively is necessary for four or more, is attached thereto cross bar, brace or the auxiliary rod etc. that connect and quantitatively also should correspondingly increases, and the erection work amount is big, installation time is long; Its materials are also many simultaneously, and cost is higher.2, as the pyramidal structure of square or rectangle, its floor space is more, is subjected to the restriction of landform easily.

In addition, in present communication and power domain, also has the iron tower of triangular structure form.The principal post of this iron tower is not outer to be following two kinds of structures: cancelled structure; Or directly adopt seamless steel pipe.There are defectives such as above-mentioned member is many, workload is big equally for cancelled structure.And adopt the iron tower of seamless steel pipe for its principal post, also have poor, the single basic steel using amount of manufacturability big, be difficult for defectives such as transportation and installation.

Summary of the invention

The purpose of this utility model is that to solve in the existing iron tower technical problem such as existing above-mentioned defective and a kind of special section bar is provided be angle section, and the tower or the iron tower that utilize this special section bar to constitute.

Special section bar of the present utility model is formed by the light-gauge steel section clod wash, has two sakes, and constitutes horn shape by this two sake, and this two sake is symmetrical.

Two above-mentioned sakes constitute by 2 planar sections that clod wash forms, and first planar section 11 wherein constitutes an angle of 90 degrees mutually, and the extended line of its second planar section 12 constitutes 60 degree angles.

Iron tower of the present utility model includes three principal posts, a plurality of cross bar, and cross bar links to each other with principal post; Principal post is above-mentioned special section bar; Described three principal posts are in the place, three bights of similar equilateral triangle.

Angle section of the present utility model is formed by clod washes such as thin plates, it is that section configuration by changing thin plate is to reach the purpose that improves bearing capacity and economical with materials, compare characteristics such as have that the section distribution of material is reasonable, the radius of gyration is big, bending resistance and torsional property are good with the rolling section bar of tradition.This tower can directly adopt securing member to be linked and packed owing to adopt special cold-forming shapes, and good manufacturability has improved its anti-bending strength and stability thereof effectively.Dan Jiyong material amount is compared with square or rectangle tower can reduce by 20%, and it is little to be easy to transportation and installation and floor space, can reduce total production cost widely.

The specific embodiment

Referring to Fig. 1 and Fig. 2, special section bar 1 of the present utility model is formed by the light-gauge steel section clod wash, has two sakes, and constitutes horn shape by this two sake, and this two sake is symmetrical; This two sake constitutes by 2 planar sections that clod wash forms, and first planar section 11 wherein constitutes an angle of 90 degrees mutually, and the extended line of its second planar section 12 constitutes 60 degree angles.

The diverse location place of above-mentioned special section bar has pilot hole.Be convenient to assemble the formation tower with cross bar etc.

Above-mentioned special section bar can process in the following ways: 90 traditional hot rolling equal leg angles by roll extrusion or pressure processing, are formed the special cold-rolled forming section of 60 degree.Concrete technology is as follows: feeding-punching-customized cut-off-storing-rolling and processing-alignment-discharging.

Referring to Fig. 3, Fig. 4 and Fig. 5, the tower shown in the figure includes three principal posts 21, a plurality of cross bar 22, and cross bar 22 links to each other with principal post 21; Described principal post 21 is above-mentioned special section bar 1; Described three principal posts 21 are in the place, three bights of similar equilateral triangle.
