Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of frame type tower connection structures, and in particular relates to a main column and rod connection structure used on a frame type tower. Background Art
[0002] In recent years, the frame tower form has been used more and more in various fields. The main column and the rod are connected by a single plate connection, which has the following defects:
[0003] 1. The single plate and the main column are almost linearly welded, the positive pressure area is small, the pressure is huge, the local internal pressure stress concentration phenomenon of the cylinder is serious, and it is very easy to be dented at the linear welding point;
[0004] 2. Both ends of the single plate welding are mutation points of the welding area, which are typical stress concentration areas in fracture mechanics. They have extremely low bending resistance and are very easy to bend and break. Utility Model Content
[0005] In order to overcome the above technical problems existing in the prior art, the purpose of the utility model is to provide a connection structure for a frame-type tower, which is easy to process and eliminates stress concentration areas.
[0006] The utility model provides a connection structure for a frame-type tower, comprising a main column and an inclined rod, wherein the main column is provided with a gradually expanding saddle-shaped bottom opening, and the inclined rod is installed on the saddle-shaped bottom opening of the main column.
[0007] The saddle-shaped bottom opening is a conical expansion opening in terms of macroscopic dimensions.
[0008] The saddle-shaped bottom opening comprises an upper wing plate, a lower wing plate and a web plate. The upper wing plate and the lower wing plate are arc-shaped plates with convex surfaces facing each other. The web plate is arranged between the upper wing plate and the lower wing plate.
[0009] The curvature of the upper wing plate and the lower wing plate is designed according to the angle of the diagonal rod.
[0010] The web is a flat plate, and the web is connected to the diagonal rod through bolts.
[0011] A backing plate is provided between the web and the diagonal rod, and a connecting clamping plate is provided between the diagonal rod and the bolt.
[0012] The utility model provides a connection structure for a frame-type tower, which has the beneficial effect that a gradually expanding saddle-shaped bottom is adopted for the main column side connection, the connection area is several times larger than the area of the current single-plate line, the compressive stress is reduced several times, and the extrusion depression phenomenon is eliminated; the upper and lower wing plates are arranged in an arc shape, which eliminates the cross-sectional area mutation phenomenon, eliminates the fracture stress concentration area, and can also play a role in pressure dispersion and transmission, the bending resistance cross-sectional area is increased several times, the compressive stress and the tensile stress are reduced exponentially, and the bending resistance is improved several times; the processing cycle of the connector is short, the processing CNC degree is high, the processing efficiency is high, and the processing quality is easy to control.
