Technical Field

[0001] The utility model relates to the technical field of bridge decoration, in particular to an inverted trapezoidal truss hanging basket for bridge appearance decoration. Background Technique

[0002] At present, after the pier is capped, its surface appearance needs to be decorated. Due to many risk factors in high-altitude operations, large construction volume, relatively harsh regional climate and other factors, a safe and reliable operation platform is required for high-altitude operations. During the process of pier appearance decoration, a special bridge truss hanging basket is selected for construction, which is convenient to disassemble, safe and reliable, and can ensure the smooth progress of construction. The hanging basket can also be used for local construction and appearance decoration of structures such as high retaining walls.

[0003] At present, when decorating a wider pier, the truss hanging basket required has a large span, and the longitudinal main beam is prone to deformation due to the load, and at the same time, the two ends are prone to shaking, which has a great impact on the safety of construction. Content of the Utility Model

The plurality of metal frames are welded end to end in pairs to form a truss. Rectangular steel pipes are welded at both sides near the top of the truss. A trapezoidal truss is welded in the middle at the bottom of the truss, and the small end face of the trapezoidal truss faces downward. The metal frames and the trapezoidal truss are both formed by hollow steel pipes intersecting and welding with each other.

[0007] Optionally, first inclined rods are obliquely welded on both sides of the plurality of metal frames, and second inclined rods are obliquely welded on the front and back sides of the plurality of metal frames.

[0008] Optionally, anti-slip plates are laid at the bottoms of the plurality of metal frames.

[0009] Optionally, lifting rings are welded on the tops of two of the metal frames, and lifting ropes are wound around the plurality of lifting rings.

[0010] Optionally, hexagonal holes are opened at both sides near the top of the rectangular steel pipe, and hexagonal pressing blocks are slidably connected between the inner walls of the plurality of hexagonal holes.

[0011] Optionally, two threaded rings are fixed on the inner bottom surface of the rectangular steel pipe, and threaded rods are threadedly connected between the inner walls of the two threaded rings.

[0012] Optionally, the tops of the two threaded rods are respectively rotatably connected to the bottom of the hexagonal pressing block, the bottoms of the two threaded rods respectively slide through to the lower side of the rectangular steel pipe, and adjusting grooves are formed at the bottoms of the two threaded rods.

[0013] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described below:

[0014] 1. In the utility model, a trapezoidal truss is welded at the bottom of the truss formed by welding multiple metal frames, and the small end face of the trapezoidal truss faces downward, so as to form an inverted trapezoidal structure with the truss formed by welding the metal frames, thereby improving the strength of the truss formed by welding the metal frames, avoiding the deformation of the longitudinal main beam due to load-bearing during large-span, and also avoiding the shaking at both ends. When welding the metal frames and the trapezoidal truss, they are both formed by intersecting welding of hollow steel pipes, which can reduce the overall weight.

[0015] 2. In the utility model, a rectangular steel pipe is welded on the truss formed by welding the metal frames, and a hexagonal pressing block is arranged inside the hexagonal hole on the rectangular steel pipe.

DETAILED DESCRIPTION

[0026] The utility model will now be further described in detail with reference to the accompanying drawings.

[0027] Embodiment 1, as Figure 1-6 As shown, the utility model provides a technical solution for an inverted trapezoidal truss hanging basket for modifying the appearance of a bridge: it includes a plurality of metal frames 1, and the plurality of metal frames 1 are welded end to end in pairs to form a truss, and rectangular steel pipes 8 are welded to the top of the truss near the edges on both sides, and a trapezoidal truss 7 is welded to the bottom of the truss in the middle, and the small end face of the trapezoidal truss 7 faces downward, and the metal frames 1 and the trapezoidal truss 7 are both formed by hollow steel pipes welded to each other in an interlaced manner.

[0028] The effect achieved by the entire embodiment 1 is that a trapezoidal truss 7 is welded at the bottom of a truss formed by welding a plurality of metal frames 1 to each other, and the small end face of the trapezoidal truss 7 is directed downward, so that an inverted trapezoidal structure is formed between the truss and the metal frames 1, thereby improving the strength of the truss formed by welding the metal frames 1 to each other, and avoiding the deformation of the longitudinal main beam due to the load-bearing when the span is large, and the shaking of the two ends. When welding the metal frames 1 and the trapezoidal truss 7, they are both made of hollow steel pipes welded to each other, which can reduce the overall weight.

[0029] Embodiment 2, as Figure 1-6As shown in the figure, first diagonal bars 2 are obliquely welded to both sides of multiple metal frames 1, second diagonal bars 3 are obliquely welded to the front and rear sides of multiple metal frames 1, anti-slip plates 6 are laid on the bottoms of multiple metal frames 1, lifting rings 5 are welded to the tops of two of the metal frames 1, lifting ropes 4 are wound around multiple lifting rings 5, hexagonal holes 9 are formed near the edges on both sides of the top of a rectangular steel pipe 8, hexagonal pressing blocks 10 are slidably connected between the inner walls of multiple hexagonal holes 9, two threaded rings 12 are fixed to the inner bottom surface of the rectangular steel pipe 8, threaded rods 11 are threadedly connected between the inner walls of two threaded rings 12, the tops of two threaded rods 11 are correspondingly rotatably connected to the bottom of the hexagonal pressing block 10, the bottoms of two threaded rods 11 correspondingly slide through to the lower side of the rectangular steel pipe 8, and adjusting grooves 13 are formed at the bottoms of two threaded rods 11.

[0030] The overall effect achieved by the entire Embodiment 2 is that a rectangular steel pipe 8 is welded to the truss formed by welding the metal frames 1 to each other, and a hexagonal pressing block 10 is arranged inside the hexagonal hole 9 on the rectangular steel pipe 8. When the truss formed by welding the metal frames 1 to each other comes into contact with the bottom of the bridge pier, by rotating the threaded rod 11, the hexagonal pressing block 10 can be jacked upward from inside the hexagonal hole 9, so that the top of the hexagonal pressing block 10 comes into contact with the bottom of the bridge pier, avoiding the situation that the top of the truss formed by welding the metal frames 1 to each other does not fit tightly due to the unevenness of the bottom of the bridge pier, thereby causing shaking.

[0031] Working principle: A trapezoidal truss 7 is welded to the bottom of the truss formed by welding multiple metal frames 1 to each other, and the small end face of the trapezoidal truss 7 is oriented downward, so as to form an inverted trapezoidal structure between it and the truss formed by welding the metal frames 1 to each other, thereby improving the strength of the truss formed by welding the metal frames 1 to each other, avoiding the situation that when the span is large, the longitudinal main beam is prone to deformation due to the load and the two ends are prone to shaking. When welding the metal frames 1 and the trapezoidal truss 7, they are both formed by interlaced welding of hollow steel pipes, which can reduce their overall weight. A rectangular steel pipe 8 is welded to the truss formed by welding the metal frames 1 to each other, and a hexagonal pressing block 10 is arranged inside the hexagonal hole 9 on the rectangular steel pipe 8. When the truss formed by welding the metal frames 1 to each other comes into contact with the bottom of the bridge pier, by rotating the threaded rod 11, the hexagonal pressing block 10 can be jacked upward from inside the hexagonal hole 9, so that the top of the hexagonal pressing block 10 comes into contact with the bottom of the bridge pier, avoiding the situation that the top of the truss formed by welding the metal frames 1 to each other does not fit tightly due to the unevenness of the bottom of the bridge pier, thereby causing shaking.
