Detailed Description
The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and in the description of the present invention, the embodiments described below are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example 1: according to fig. 1-5, a wire tower base pre-embedded screw fixing device comprises a ground base 8; a plurality of upward extending columns 7 are arranged on the foundation base; 4 vertically extending foundation screws 1 are arranged on the column body and distributed in a rectangular or rhombic shape; a reinforcement cage body for binding is arranged in the foundation base; the bottom of the foundation screw 1 extends into the ground base and is bound or welded on the reinforcement cage body; the foundation screw is provided with a metal sleeve 2 which is sleeved in a sliding manner; the outer side surface of the sleeve is provided with an upper connecting pipe 3 and a lower connecting pipe 6 which are vertically connected; the upper connecting pipe and the lower connecting pipe are positioned on the same vertical line; the upper connecting pipe and the lower connecting pipe are respectively provided with a socket 5; and connecting ribs 4 are inserted between the two sleeve openings which are distributed diagonally.
The inner diameter of the sleeve 2 corresponds to that of the foundation screw, and the sleeve has damping friction force when sliding and rotating on the foundation screw; the length of the sleeve is 100-150mm, the wall thickness of the sleeve is 4-6mm, and the upper connecting pipe and the lower connecting pipe are vertically connected to one side of the sleeve.
