Description

Technical Field

[0001] The utility model relates to the field of construction engineering, and particularly relates to a bridge decorative board device. Background Art

[0002] Most of the existing exterior decorative boards for buildings or bridges are composed of a skeleton, a board, and hardware fixtures. The keel is made of steel, aluminum profiles, stainless steel cables, stainless steel tie rods, etc.; the panel is made of stone, stone imitation, glass, aluminum veneer, aluminum plastic board, plastic board, etc.; the fixtures are made of steel parts, embedded plates, aluminum angle codes, aluminum hangers, dry hangers, stainless steel screws, bolts, and anchor bolts.

[0003] The following engineering difficulties exist in the current project:

[0004] (1) For the landscape requirement, the longitudinal block of the decorative board should be not less than 3 meters in the bridge direction, and the transverse joints should be reduced as much as possible (not less than 1.5 meters). The decorative board is required to have sufficient stiffness and a flat outer surface. Screws should not be exposed.

[0005] (2) The space inside the decorative board is narrow, and personnel cannot enter, so operations can only be carried out on the outside.

[0006] (3) The drain pipes, water collection pipes, pipelines, etc. need to be repaired at uncertain positions and times, that is, the decorative board must be convenient for disassembly and installation.

[0007] (4) The decorative board is about 30 meters above the ground under the bridge and is in water, so maintenance can only be carried out from the bridge deck using a bridge inspection vehicle, and the weight of the decorative board cannot be too large.

[0008] (5) The decorative board is part of the bridge structure, and the anchoring must be reliable and the durability requirement is high. Except for pipeline maintenance, the decorative board is not disassembled and installed within the service life of the bridge.

[0009] (6) The main bridge is made of steel structure, and the appearance, color, and gloss of the decorative board of the approach bridge need to be coordinated with the main bridge.

[0010] The prior art mostly uses the bracket method to install the integral steel exterior decorative board or uses the conventional keel + decorative board.

As Figure 1As shown, the cast-in-place box girder's outer cantilever is 2 meters long transversely across the bridge. The space under the cantilever is approximately 1.55 meters. An 800-mm inner diameter drainage pipe, multiple strands of power and signal lines are hung under the cantilever, and a set of bridge deck water collectors is set every about 15 meters. According to the landscape requirements, decorative panels are set outside the cantilever, and landscape light strips 4 are set on the decorative panels.

[0034] Figure 2 and Figure 3 Fig. shows the overall structural schematic diagram and the frame beam structural schematic diagram of the bridge decorative panel device according to an embodiment of the present invention.

[0035] Figure 4 Fig. shows the structural schematic diagram of the decorative panel of the bridge decorative panel device according to an embodiment of the present invention. As Figure 4 shown, the decorative panel of the bridge decorative panel device is made of aluminum alloy. On the premise of meeting the equipment lifting capacity, the size is as large as possible transversely across the bridge. Stiffening ribs are arranged on it to strengthen the stiffness and strength of the decorative panel.

[0036] According to an embodiment of the present invention, the specifications and structural arrangements of the square steel are determined according to the force analysis, and it is prefabricated in the whole factory and arranged at intervals longitudinally along the bridge; the specifications of the anchor bolts are determined according to the force, and they are set by means of embedded installation, post-implanted reinforcement or expansion bolts.

[0037] According to an embodiment of the present invention, the square steel is provided with drilled holes, and the self-locking bolts are installed on it.

[0038] According to an embodiment of the present invention, the self-locking bolts are made of stainless steel.

[0039] In the prior art, the integral steel outer decorative panel or the conventional keel + decorative panel is usually installed by the support method. However, such methods have problems such as narrow space inside the decorative panel that is not easy to operate, inconvenient disassembly and installation of the decorative panel, and non-meeting of the durability requirements. The embodiment of the present invention provides a reliable support for the decorative panel by setting a square steel frame beam and can avoid pipelines; the decorative panel is made of steel structure, and its shape and size are easy to meet various requirements, and it is relatively easy to process in the factory; the use of the panel and the stiffening ribs can reduce the occupied space and lighten the weight while meeting the requirements of stiffness and strength; the use of stainless steel self-locking bolts (flat head) can reliably fix the decorative panel on the frame beam, and the installation operation can be realized outside the decorative panel without space limitation; the self-locking bolts are made of stainless steel, meeting the structural durability requirements, solving the problems existing in the above prior art, being convenient for processing, disassembly and installation, and having sufficient self-stiffness to meet the durability requirements.
