Example 1
Referring to fig. 1 to fig. 3, the spiral concrete precast column for the overhead transmission line of the embodiment is characterized in that: the hollow-core-type solar cell panel comprises a column body 100 and a cavity 120 in the column body 100, wherein fixing columns 110 parallel to the length direction of the column body 100 are arranged in the column body 100, the fixing columns 110 are arranged into lower rows of columns 111 and upper rows of columns 112, a central net layer 140 is arranged between the lower rows of columns 111 and the upper rows of columns 112, the central net layer 140 is formed by weaving fine iron wires, an outer net layer 130 is arranged on the outer wall of the column body 100, an inner net layer 150 is arranged on the inner wall of the column body 100, and the outer net layer 130 and the inner net layer 150 are formed by weaving. The fixing column 110 is a steel bar or a steel column. The fixing column 110, the outer mesh layer 130, the center mesh layer 140 and the inner mesh layer 150 of the column body 100 are filled with concrete. The central mesh layer 140 is welded to the lower and upper columns 111 and 112. The nodes of the outer mesh layer 130, the central mesh layer 140 and the inner mesh layer 150 are all formed by welding. In the embodiment, the lower row of columns 111 and the upper row of columns 112 provide strength support for the column body 110, the strength and the hardness in the column body are increased through the central mesh layer 140, the outer mesh layer 130 and the inner mesh layer 150, the strength and the stability of the column body 110 can be improved, and meanwhile, the central mesh layer 140, the outer mesh layer 130 and the inner mesh layer 150 are all woven by fine iron wires, so that the strength and the stability of the column body can be further increased.
The central net layer is in block chain connection with the lower rows of columns and the upper rows of columns, so that each upper row of columns can be in compound binding force with each lower row of columns, and the connection level and the connection capacity of the upper row of columns are comprehensively improved. In the block chain connection, any lower row column 111 can be rigidly connected with each upper row column 112 directly or indirectly through a connecting piece, that is, a set of connecting mechanism is added outside the central net layer 140. For example, if there are 6 lower-row columns and 6 upper-row columns, only 36 connecting pieces need to be added, and the binding force and the system stability can be greatly increased.
