Problems solved by technology

[0002] The vertical layout of the existing 750kV power distribution equipment site adopts a vertical and horizontal two-way single slope with a slope of 5‰, and the height difference between the highest point and the lowest point of the site is about 1.2m, which brings great difficulties to the foundation design of the 750kV frame structure
[0003] The foundation of the conventional frame structure is generally buried at the same level, the length of the frame columns is the same, and the bottom of the beam is horizontal, but when the site slope is large, if the foundation of the frame structure is still buried at the same height, the height of the frame columns will be different. The number of components is large, and the construction and installation are inconvenient

Embodiment 1

[0032] Such as figure 1 As shown, in this embodiment, a 750kV frame structure suitable for sites with relatively large slopes is specifically disclosed, including several frame columns 1. The bottom end of each frame column 1 is buried in the site at the same depth, and the embedment depth of each frame column 1 relative to the surface of the site is the same, and the site is simulated as a standard slope, then each frame column The vertical spacing between the top of 1 and the surface of the site is equal, which can also be understood as the same vertex of each frame column 1 is connected to form a "face", and the "face" should be parallel to the slope of the site. Preferably, the frame The column 1 includes several A-shaped steel pipe columns, and the use of the A-shaped steel pipe columns to form the frame column 1 can ensure that the frame column 1 has good stability and bearing capacity.

[0033] Such as figure 2 As shown, at least one frame beam 2 is arranged between ...

Embodiment 2

[0039] In Example 1, in order to realize the pre-positioning of the beam inserting plate 7, the method of increasing the frictional force is adopted. This method has low reliability, and in the assembly process, the assembly is difficult and labor-intensive. The concept of convenient and quick installation in the process, therefore, on the basis of Embodiment 1, the following structural design is adopted to realize convenient and quick pre-positioning during the installation process of the beam inserting plate 7, such as Figure 8 , Figure 9 As shown, as follows:

[0040] It also includes a rotary sleeve 13 that is placed on the beam chord 6, and a plurality of arc clips 15 are arranged on the circumferential direction of the rotary sleeve 13, and each arc clip 15 is formed with the beam chord 6. Concentric arrangement and the same side of each arc clamping plate 15 are all provided with clamping head, and each described arc clamping plate 15 is respectively positioned betwe...

Abstract

The invention discloses a 750 kV framework structure suitable for a large-gradient site, and belongs to the technical field of electric power project extra-high-voltage direct-current transmission. The 750 kV framework structure comprises multiple framework columns. The bottom ends of all the framework columns are buried at the same depth relative to the surface of the site, and at least one framework beam is arranged between every two adjacent framework columns. The two ends of all the framework beams are assembled on the every two adjacent framework columns through beam and column joints correspondingly, the straight line direction where all the framework beams are located is parallel to the inclination direction where the gradient of the site is located, and therefore the purposes thatthe requirements of electrical engineering for charged distances are met, the joints are convenient to mount, and good economic benefits are achieved are achieved.

Description

technical field [0001] The invention belongs to the technical field of ultra-high voltage direct current transmission in electric power engineering, and relates to the professional frame technology of civil engineering structures, in particular, to a 750kV frame structure suitable for large slope sites. Background technique [0002] The vertical layout of the existing 750kV power distribution equipment site adopts a vertical and horizontal two-way single slope with a slope of 5‰, and the height difference between the highest point and the lowest point of the site is about 1.2m, which brings great difficulties to the foundation design of the 750kV frame structure. [0003] The foundation of the conventional frame structure is generally buried at the same level, the length of the frame columns is the same, and the bottom of the beam is horizontal, but when the site slope is large, if the foundation of the frame structure is still buried at the same height, the height of the fra...
