The utility model provides a kind of triangle steel tubular beam substation framework, including three horizontal support bars, and being equally spaced between three horizontal support bars has some triangle tube beams；Described triangle tube beam is the isosceles triangle being made up of three steel pipes, and three seam crossings of three horizontal support bars through three steel pipes are fixed by side connecting plate and triangle tube beam；Bearing diagonal steel pipe is connected between each triangle tube back portion's seam crossing and adjacent triangle tube beam bottom seam, bearing diagonal steel pipe is fixed by side connecting plate and triangle tube beam；Three described horizontal support bars are formed by connecting by some horizontal steel tubes by flange, and the angle between adjacent two horizontal steel tubes is less than 0.1 °.Substation framework provided by the utility model, product quality and overall girder steel appearance and size are easily controllable, and bearing diagonal steel pipe is not allowed to be also easy to produce cheaply, it is ensured that the pre- arch of triangle steel tubular beam meets Design Requirement Drawing and acceptance specification standard.
Description
Technical field
Substation framework field is the utility model is related to, specifically a kind of triangle steel tubular beam substation framework.
Background technology
The design of existing substation framework, setting-out technique personnel consider when carrying out making setting-out with reference to product design drawing
Weight issue to steel tubular beam deadweight and to hanging wire point weight, camber line design setting-out is carried out to triangular beam camber, passes through drafting
Camber line degree calculates each element structure length（Such as angle cleat, connecting plate）, reach and meet that drawing encircles requirement in advance.
Problems with actual fabrication be present using the design setting-out of camber line degree：
（1）Because the elongation percentage of steel pipe radian and material is difficult to control, the position for being also easy to produce each node shifts, and makes connection
Brace is not intersected in node center（See Fig. 1）.
（2）Main material steel pipe encircles radian in advance can change or deform in galvanizing process.
（3）Because main material steel pipe encircles the change of radian or deformation causes product very difficult in an assembling process, triangle in advance
Shape girder steel monnolithic case does not reach preferable shape, and appearance and size does not reach yet and meets the requirement of drawing size.
（4）Technical staff's design setting-out difficulty is also big, and each scantling length is difficult to control.
Utility model content
The utility model is in order to solve problem of the prior art, there is provided a kind of triangle steel tubular beam substation framework, product
Quality and overall girder steel appearance and size are easily controllable, and bearing diagonal steel pipe is not allowed to be also easy to produce cheap, it is ensured that triangle steel tubular beam it is pre-
Arch meets Design Requirement Drawing and acceptance specification standard.
The utility model includes three horizontal support bars, and being equally spaced between three horizontal support bars has some triangle tubes
Beam, horizontal support bar pass perpendicularly through the plane where triangle tube beam；Described triangle tube beam is made up of three steel pipes
Isosceles triangle, wherein thread gripping-board is installed on a steel pipe, three seam crossings of three horizontal support bars through three steel pipes
Fixed by side connecting plate and triangle tube beam；Each triangle tube back portion's seam crossing connects with adjacent triangle tube beam bottom
Bearing diagonal steel pipe is connected between seam, bearing diagonal steel pipe is fixed by side connecting plate and triangle tube beam；Three described water
Flat support bar is formed by connecting by some horizontal steel tubes by flange, and the angle between adjacent two horizontal steel tubes is less than 0.1 °.
Two horizontal support bar both ends of lower section are fixed by support base in three described horizontal support bars.
The utility model beneficial effect is：
1st, product quality and overall girder steel appearance and size are easily controllable, and bearing diagonal steel pipe is not allowed to be also easy to produce cheaply, it is ensured that three
The pre- arch of angular steel tubular beam meets Design Requirement Drawing and acceptance specification standard.
2nd, it is easy to workmen to be easily assembled at the construction field (site), it is ensured that assembling is with regard to bit rate 100%.
3rd, provide thinking for similar steel structure girder processing and fabricating camber issue handling and solve method.
4th, do not influenceed by zincincation.
5th, steel pipe axis and Flange Plane angle will not be influenceed and be deformed by welding procedure, it is ensured that product quality is stable.
6th, it is easy to assembled personnel to make pattern specification by oneself in production process, joining quality is stable, there is provided production efficiency.
Brief description of the drawings

Fig. 2 is the utility model structure diagram.
Fig. 3 is the utility model triangle tube girder construction schematic diagram.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
The utility model structure is equidistantly divided as shown in Fig. 2 including three horizontal support bars 1 between three horizontal support bars 1
Some triangle tube beams 3 are furnished with, horizontal support bar 1 passes perpendicularly through the plane where triangle tube beam 3, described three horizontal branch
Two horizontal support bar both ends of lower section are fixed by support base 6 in strut 1.
Described triangle tube beam 3 is as shown in Fig. 2 isosceles triangle to be made up of three steel pipes, wherein a steel pipe
On thread gripping-board 5 is installed, three seam crossings of three horizontal support bars 1 through three steel pipes pass through side connecting plate 2 and triangle
Pipe beam 3 is fixed；Oblique branch is connected with each top seam of triangle tube beam 3 and between adjacent triangle tube beam bottom seam
Steel pipe is supportted, bearing diagonal steel pipe is fixed by side connecting plate 2 and triangle tube beam 3；If three described horizontal support bars 1 are by solid carbon dioxide
Flat steel pipe is formed by connecting by flange 4, and the angle between adjacent two horizontal steel tubes is less than 0.1 °.
The pre- arch design of triangle steel tubular beam, technical staff should according to girder steel length that product drawing provides, girder steel height,
The predomed height of girder steel bottom width and girder steel, connected using triangle geometry principle with regard to that can draw out or calculate each node
Component length size.
The utility model concrete application approach is a lot, and described above is only preferred embodiment of the present utility model, should
Point out, for those skilled in the art, on the premise of the utility model principle is not departed from, can also make
Go out some improvement, these improvement also should be regarded as the scope of protection of the utility model.
