Detailed Description
The features of the present invention and other related features are described in further detail below by way of example in conjunction with the accompanying drawings to facilitate understanding by those skilled in the art:
as shown in fig. 1-4, the labels 1-8 in the figures are respectively expressed as: hanging flower basket platform 1, support 2, horizontal angle steel 3, spiral stair 4, mound top rail 5, pier 6, angle steel support 7, steel lattice board 8, round steel 9.
Example (b): referring to fig. 1 and 2, the main body of the pier suspension fence in this embodiment includes a gondola 1, an angle bracket 7, a spiral staircase 4, and a pier top rail 5. The enclosed area of the hanging basket platform 1 and the spiral stair 4 is matched with the outer contour shape and size of the pier and is symmetrically arranged with the pier 6. The hanging basket platform 1 is formed by combining a horizontal angle steel 3 and a plurality of L-shaped supports 2, and the supports 2 are arranged at intervals along the length direction of the horizontal angle steel 3 to meet the requirement of supporting strength; the horizontal angle steel 3 is installed at the horizontal part of the bracket 2 and connected with the bracket through a bolt, so that the installation or replacement is convenient.
The vertical parts of the brackets 2 are connected through round steel 9 and form a whole, and the structural integrity and the stability of the brackets 2 are effectively improved on the premise of ensuring safety protection. In the specific implementation: the vertical part of the support 2 is provided with mounting holes matched with the round steel 9 in diameter, the round steel 9 integrally penetrates through the mounting holes formed in each support 2 at the single-side hanging basket platform 1, and the two ends of the round steel 9 are screwed and fixed with the supports 2 positioned on the two sides through galvanized screws.
As shown in fig. 4, a steel lattice plate 8 is laid on the horizontal angle steel 3 as a step for an operator to walk. At this time, since the outer side of the steel lattice plate 8 is surrounded by the vertical portion of the bracket 2 and the round steel 9, the personal safety of the operator walking on the steel lattice plate 8 can be ensured.
As shown in fig. 1 and 2, a pier top fence 5 is provided on the top of the pier 6, and the gondola 1 is provided below the pier top, and communication is established by providing spiral stairs 4 therebetween, so that an operator can move and switch between the working area of the gondola 1 and the pier top working area in the pier top fence 5 by the spiral stairs 4. Specifically, spiral stair 4 installs the corner tip at the hanging flower basket platform and its bottom is connected fixedly with hanging flower basket platform 1, and the top constitutes fixedly through implanting chemical anchor bolt with the pier top of pier 6.
