Description

Technical Field

[0001] The present invention relates to a bridge lighting structure, belonging to the technical field of bridge construction. Background Art

[0002] Due to the need to build the main body of the bridge and the surrounding landscape, the night effect of municipal bridges usually requires auxiliary decorative lamps. The implementation methods of the lamps are mainly as follows: 1) Conventional decorative lamps are purchased as finished products, and the finished lamps generally consist of an internal light source and an external transparent lamp surface; 2) Unconventional lamps can be customized by factories. The shape and size of the lamp surface of the customized lamps are greatly restricted by the mold. A small number of lamps cannot be customized by factories. The lamp surface can also be made of fiberglass, which is convenient for processing and manufacturing, but the fiberglass has poor light transmittance and poor landscape effect. To meet the requirements of external illuminance, lamps with large external dimensions must use internal high-power light sources, resulting in a large amount of heat generated by the high-power light sources, affecting the service life of the lamps or increasing temperature control equipment; lamps with large external dimensions must be provided with an internal skeleton to maintain the stability of the lamp surface. Under the illumination of the internal light source, the image of the internal skeleton will appear on the lamp surface, affecting the landscape effect; 3) The effect of the external projection light scheme is uneven, and the external projection light source affects the landscape effect, and the landscape effect is worse than the self-luminous effect. At present, there is no mature solution for designing lamps with large-sized and spatially irregular lamp surfaces. Summary of the Invention

[0003] The technical problem to be solved by the present invention is: to provide a bridge lighting structure that can form lamps with arbitrarily large-sized and spatially irregular lamp surfaces.

[0004] The technical solution adopted by the present invention to solve the above technical problem is: a bridge lighting structure, including a bridge tower. A lamp installation metal panel is arranged on the outer peripheral direction of the bridge tower. One side of the lamp installation metal panel facing the bridge tower is fixedly connected with the bridge tower through a fixed framework. A plurality of installation holes are arranged on the lamp installation metal panel, and lamps are installed in the installation holes.

[0005] Further: the lamp installation metal panel is a steel plate, and the fixed framework is a steel structure bracket.

[0006] Further: the fixed framework includes a back rib fixedly connected with the lamp installation metal panel and an internal skeleton fixedly connected with the bridge tower. The back rib is arranged along the main body length direction of the lamp installation metal panel. The back rib and the internal skeleton are fixedly connected and fixed through connecting legs and bolts. The connecting legs are multiple pieces arranged at intervals along the main body length direction of the lamp installation metal panel.

[0007] Further: the fixed framework and the lamp installation metal panel are connected by metal anchor chains or elastic ropes. The metal anchor chains and the elastic ropes are multiple pieces arranged at intervals along the main body length direction of the lamp installation metal panel.

[0008] The beneficial effects of the present invention are as follows: The main structure is made of steel, enabling the realization of a spatially irregular lamp surface for the lamp, without the need for specialized mold equipment; the lamp is directly installed in the mounting holes on the metal lamp mounting panel, adopting a self-luminous form, which can ensure the landscape effect. When realizing large-sized lamps, the landscape effect is not restricted by the internal skeleton and high-power internal light sources, and at the same time, the requirements for landscape illumination are met. In addition, an anti-drop device (metal anchor chain or elastic rope) is added to the shaping structure for the tower top decoration, which can add an additional safety line to avoid safety accidents caused by the falling of components after the connection fails.

[0014] For the convenience of understanding and implementing the present invention, the preferred embodiments of the present invention are selected and further described in conjunction with the accompanying drawings.

[0015] As shown in Figure 1 and Figure 2As shown in the figure, the bridge lighting structure in the present invention includes a bridge tower 1. A lighting fixture installation metal panel 2 is arranged in the circumferential direction of the bridge tower 1. One side of the lighting fixture installation metal panel 2 facing the bridge tower 1 is fixedly connected to the bridge tower 1 through a fixed frame 3. A plurality of installation holes are provided on the lighting fixture installation metal panel 2, and lighting fixtures are installed in the installation holes. Among them, the lighting fixture installation metal panel 2 can be made of metal panels of any material. Considering structural reliability and manufacturing cost, it is preferably made of steel plates. Similarly, the fixed frame 3 is preferably a steel structure support. During implementation, the lamp surface (i.e., the lighting fixture installation metal panel 2) is made according to the shape of the lighting fixture, and a lamp surface of any large size and spatial special shape can be formed, not limited to the circular arrangement shown in the drawings. A plurality of installation holes are provided on the lighting fixture installation metal panel 2, and the arrangement spacing and size of the installation holes should be determined according to conditions such as the installation location of the lighting fixture, the height from the ground, climate conditions, landscape effects, and the size of the light source in the holes. The lighting fixtures are directly installed in the installation holes on the lighting fixture installation metal panel 2 and adopt a self-luminous form, which can ensure the landscape effect.

[0016] For convenient assembly and at the same time effectively ensuring the reliability of the overall structure, the fixed frame 3 can adopt the following structural form: The fixed frame 3 includes a back rib 31 fixedly connected to the lighting fixture installation metal panel 2 and an inner skeleton 32 fixedly connected to the bridge tower 1. The back rib 31 is arranged along the main length direction of the lighting fixture installation metal panel 2. The back rib 31 and the inner skeleton 32 are connected and fixed through a connecting leg 33 and a bolt 34. The connecting legs 33 are multiple pieces arranged at intervals along the main length direction of the lighting fixture installation metal panel 2. Among them, the back rib 31 can play the role of a reinforcing rib. Combined with the multi-point connection of the connecting legs 33, the structural reliability can be effectively ensured. Using bolt 34 for connection can facilitate on-site assembly.

[0017] Since the lighting structure is located at the top of the bridge tower 1, with busy traffic and people flow below it, once a connection failure occurs and components fall, the consequences will be extremely serious. As Figure 3 and Figure 4 shown, preferably, in the present invention, a metal anchor chain 4 or an elastic rope is connected between the fixed frame 3 and the lighting fixture installation metal panel 2. The metal anchor chains 4 and the elastic ropes are multiple pieces arranged at intervals along the main length direction of the lighting fixture installation metal panel 2. In this embodiment, the metal anchor chain 4 is connected between the back rib 31 and the inner skeleton 32, and the metal anchor chain 4 is in a relaxed state during installation to avoid the anchor chain being too long (if the anchor chain is too long, the impact on the anchor chain will be too large when the panel falls off). When the connection fails due to external reasons, the anchor chain can still connect the panel to the main skeleton, avoiding a safety accident caused by the panel falling from a high altitude.

[0018] The present invention can be implemented according to the following steps:

[0019] 1) Construct the bridge tower structure according to the conventional plan;

[0020] 2) Process the metal panel for lamp installation on the ground, drill holes on the panel, and add back ribs on the back of the panel;

[0021] 3) Place the inner skeleton on the top of the tower;

[0022] 4) Install the connecting legs on the inner skeleton;

[0023] 5) Lift and install the metal panel for lamp installation, and connect the panel to the connecting legs using the back ribs;

[0024] 6) Connect the metal panel for lamp installation to the inner skeleton with metal anchor chains;

[0025] 7) Install small light sources in the installation holes of the metal panel for lamp installation.
