Abstract

The invention discloses a supporting rod with a length adjusting device. The supporting rod comprises an inner steel pipe at the upper part, an outer steel pipe at the lower part and the length adjusting device arranged between the inner steel pipe and the outer steel pipe, wherein the length adjusting device comprises an outer pipe provided with an external thread at the end part, an inner pipe which has the diameter smaller than that of the outer pipe and is provided with an insertion hole in the pipe wall, as well as a length adjuster consisting of a ring nut, spanners and an inserted pin; the inner pipe is inserted into the outer pipe; the inserted pin is inserted into the insertion hole of the inner pipe; the ring nut is in threaded connection with the outer pipe provided with the external thread; and the spanners are arranged on the outer wall of the ring nut. According to the supporting rod with the length adjusting device, the problem of a length error generated during component manufacturing and mounting can be solved, and reliable connection is guaranteed.

Description

[0001] technical field [0002] The invention relates to the technical field of civil engineering steel structures, in particular to a support rod with a length adjusting device. Background technique [0003] The communication tower is a tall structure, and the load effect under the wind load is the main control load for its own structure and foundation calculation. The foundation must provide sufficient resistance to ensure that the upper structure does not overturn as a whole. [0004] As a support rod connecting the tower body and the foundation steel frame, the conventional practice is to use a fixed-length support rod to connect the tower body and the steel frame with ear plates. This requires a high level of precision in fabrication and installation, and cannot well regulate the inclination of the tower body. Moreover, depending on the height of the tower and the difference in the basic wind pressure, the size of the basic steel frame is different, and the length of t...
