Detailed ways

The utility model is described in detail below in conjunction with accompanying drawing and specific embodiment.

As shown in the accompanying drawings, a hanging basket suspension device of the utility model that can be used for special parts of construction projects includes a steel cantilever beam 1, and one side of the steel cantilever beam 1 is connected by a U-shaped bolt 5 The support is fixed on the support frame 2 or on the load-bearing wall. As an embodiment of the present utility model, the support frame 2 includes a base 9, and in the middle of the base 9, a vertical column 10 is fixed A connecting plate 11 , one side of the section steel cantilever beam 1 is supported on the connecting plate 11 and fixed on the connecting plate 11 of the support frame 2 through U-shaped connecting bolts 5 . Further preferably, a reinforcing rib 12 is provided on the base 9, and a diagonal brace 13 is fixed between the column and the base.

The shaped steel cantilever beam 1 on the front side of the support frame 2 is a suspension section and the shaped steel cantilever beam 1 on the rear side of the support frame 2 is an anchor section, and the rear part of the anchor section is spaced before and after. At least two anchors 7, each of the anchors 7 includes two anchoring screws 8 arranged in the vertical direction, the two anchoring screws 8 are arranged near the left and right side walls of the steel cantilever beam 1, and the two anchoring screws 8 The bottom of the bottom is connected to the base plate 4 by welding. The lower parts of the two anchoring screws 8 and the bottom plate 4 are pre-embedded in the structural plate 6, wherein the bottom plate is located at the bottom of the structural plate. The lower parts of the two anchoring screw rods are covered with PVC pipes, and the anchoring screw rods can be disassembled after use. The periphery of the top of the bottom plate has an obtuse angle, and a plastic film is pasted on the top of the bottom plate as an isolation layer, so as to facilitate separation from the structural concrete when the anchor screw is removed. A pressure beam 14 is arranged on the top wall of the anchoring section of the steel cantilever beam opposite to the two anchor screws 8, and the two anchor screws 8 pass through the bolt holes on the pressure beam 14 and are fixedly connected by nuts. A skid 15 is supported between the bottom of the anchor section on the front side of the anchor piece 7 and the structural plate 6 .
