Detailed ways

The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the protection scope of the present invention can be more clearly defined.

Referring to Figures 1 and 2, the present utility model provides a Bailey beam fixing device for suspending pipelines, comprising a steel plate 1, pre-embedded steel bars 8, four sets of steel bar connecting member mechanisms and four sets of steel sleeve members. The steel sleeve includes eight steel sleeves 2, four round openings are provided on both ends of the surface of the steel plate 1, the steel sleeves 2 are all inserted in the round openings, and the upper edge of the steel sleeve 2 is folded outward at 90° to turn over. Part 3, the inversion part 3 is fixedly welded with the upper surface of the steel plate 1, which increases the welding surface between the steel sleeve 2 and the steel plate 1, and the inversion part 3 resists the surface of the round mouth, which improves the connection between the steel sleeve 2 and the steel plate 1. Strength and stability, the four groups of steel bar connection mechanisms include eight L-shaped rods 4 and straight rods 5. The upper end of the L-shaped rod 4, the upper and lower ends of the straight rod 5 are all provided with external threads, and the inner ring surface of the steel sleeve 2 is provided with The inner thread of the external thread is matched with each other.
