Described quadrilateral lattice tower is made up of king-post, brace, secondary brace and diaphragm, described king-post is four, brace is eight, two braces are one group, two brace one end are flexibly connected, the other end connects two king-posts respectively, and namely adjacent king-post is connected by one group of brace, makes the frame structure of four king-posts and eight brace formation quadrilaterals; Four groups of brace one end are flexibly connected end and are connected by four diaphragms; Described diaphragm, to be connected by time brace between brace and king-post; Quadrilateral lattice tower is connected bottom described rectangular pyramid face.
In the utility model, one end of described four king-posts is plugged on four angles in rectangular pyramid face respectively.
In the utility model, when quadrilateral lattice tower top width is larger, longitudinal flange can be increased in the excessive section of hemispherical dome for ease of transport.Described hemispherical dome changeover portion can be made up of two panels or four longitudinal flange plates respectively at hemispherical dome planar section, is connected between adjacent longitudinal flange plate by longitudinal flange high-strength bolt.
In the utility model, described upper flange plate and lower flange plate are respectively transverse thick type forged flange.
The utility model adopts hemispherical dome curved surface excessive between cylinder section and square-section, and hemispherical dome curved surface is made up of (oblique cone face is developable surface) plane and oblique cone face simultaneously, thus adopts longitudinal butt weld to be spliced by steel plate; Hemispherical dome curved surface top is connected by thicker forged flange with single-pipe tower, and grafting is carried out by rectangular pyramid face and angle steel and quadrilateral lattice tower in bottom.When quadrilateral lattice tower top width is larger, for avoiding transport difficult, longitudinal flange can be adopted to be divided into some parts.
The utility model advantage is:
1. provide a kind of effective switching node connecting single-pipe tower and quadrilateral lattice tower, and this switching node welding capacity is less, all weld seams are butt weld, polish rear anti-fatigue performance high.
2. have very strong applicability, when quadrilateral lattice tower top width meets transportation demand, then switching node is an entirety; When exceeding transportation demand when quadrilateral lattice tower top width, longitudinal flange can be adopted node to be divided into symmetrical two panels or four.
