Description
Technical field
The invention belongs to the power engineering field, be specifically related to a kind of hollow sandwich composite material concrete power transmission tower member.
Background technology
Existing power transmission tower member mostly is angle iron component and steel tube component.Because connect and structure, angle iron component often is in the eccentric force state, its performance can not be not fully exerted; The cripling of steel tube component easily takes place prior to complete buckling, causes the utilization rate of component performance to be had a greatly reduced quality; The steel member is a conductive body, and insulator string need be set.
In order to improve the electric property of power transmission tower, do not reduce the mechanical mechanics property of power transmission tower simultaneously again, exigence those skilled in the art develops a kind of new power transmission tower member.
Summary of the invention
In order to overcome defective of the prior art, the object of the present invention is to provide a kind of electric property superior, have hollow sandwich composite material concrete power transmission tower member simultaneously than high bearing capacity.
For this reason, the present invention proposes a kind of hollow sandwich composite material concrete power transmission tower member, its improvements are: this member comprises member body of being made up of the interior pipe and the outer tube of equal in length and the connector that is located at the member body two ends, the axis of described interior pipe and outer tube coincides and leaves the sandwich portion that is used for fill concrete between the two, described connector is provided with the connecting hole that is used to connect power transmission tower, the wall thickness of pipe and outer tube is 1～12mm in described, and the wall thickness of outer tube is greater than the wall thickness of interior pipe.
Wherein, the two ends of described interior pipe and outer tube are respectively equipped with one and preset steel pipe, and described interior pipe is connected with connector by the steel pipe that presets that is installed in its end with outer tube.
Wherein, the described length that presets steel pipe is greater than the diameter of outer tube and less than the length of outer tube.
Wherein, the described steel pipe that presets is the steel pipe that is preset at interior pipe and outer tube two ends.
Wherein, the hoop tension bearing capacity of described outer tube is greater than the hoop tension bearing capacity of interior pipe.
Wherein, described interior pipe and outer tube all adopt the FRP pipe.
Wherein, described connector adopts doughnut-shaped steel plate.
The present invention compares with existing power transmission tower member and has the following advantages:
Pipe and outer tube had very high extensional rigidity and tensile strength in the present invention adopted, can improve the axially loaded performance of member, concrete that simultaneously can the operative constraint sandwich portion, and then improve concrete resistance to compression bearing capacity, and then improve tension, resistance to compression and the anti-bending strength of member integral body; Sandwich portion is inserted concrete and is had superior compressive property, can improve the axial compression resistance performance of whole member, and internally pipe and outer tube have certain effect of contraction simultaneously, can improve the stress performance of inner and outer pipe, and then can improve the mechanical property of member; In addition, interior pipe of the present invention and outer tube adopt composite material tube (FRP pipe), and good insulation preformance has superior electric property, can save insulator.
