Description

Technical Field

[0001] This invention relates to a bridge railing repair and reinforcement device, specifically to a repair and reinforcement device for a broken and aging bridge railing. Background Technology

[0002] There are numerous bridges built across China's rivers, lakes, and seas, many of which were constructed in the 1980s and 90s and remain vital transportation arteries. Due to limitations in construction techniques and costs at the time, most of these bridges used concrete pillars and balustrades, or granite pillars and carved balustrades, for their railings. The installation process for concrete pillars involved pouring cement into pre-drilled openings at the edge of the cap beam, then attaching the reinforcing steel bars at the bottom of the pillar to the cap beam. For granite pillars, pre-drilled slots were used at the edge of the cap beam; cement was poured into these slots, and the pillars were then inserted and secured. After years of use, some of these railing pillars have developed... Cracks and fractures after vehicle collisions are sometimes caused by weather or other factors, resulting in cracks and misalignment. Current methods for minor surface cracks or damage involve surface repair, using materials like resin adhesive to seal the cracks and then painting them to prevent further deterioration from moisture and corrosive substances. This has little effect on the structural load-bearing capacity. For more serious damage, such as broken guardrails requiring replacement, the repair process is slow. Due to the age of the guardrails, new installations often differ significantly in shape from the originals, resulting in a substantial reduction in both safety and aesthetics. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing methods by disclosing a repair and reinforcement device for broken and aging bridge railings. The device involves wrapping the column with an inner panel and an outer baffle A, fixing the fixing plate A and the outer baffle A to the cap beam with cement screws, and fixing the railing with an outer support plate and a clamping plate, thereby achieving repair, fixation, and impact resistance for the column and railing.

[0004] To achieve the inventive objective of this disclosure, the present application discloses the following technical solution:

[0005] A repair and reinforcement device for fractured and aging bridge railings includes a bridge cap beam, columns, and railing panels. An inner panel of a U-shaped structure wraps around the lower part of the columns. A fixing plate A on the lower inner side of the inner panel is fixed to the pedestrian walkway above the cap beam. The outer side of the inner panel is fixedly connected to both sides of the U-shaped structure above the outer baffle A. The lower part of the outer baffle A is fixed to the outer surface of the cap beam. An outer baffle C is fixed to the outer surface of the cap beam. A vertical connecting plate on the upper part of the outer baffle C is inserted between the lower surface of the railing panel and the upper surface of the cap beam. An outer support plate on the upper part of the vertical connecting plate is located outside the railing panel. A clamping plate is provided on the inner side of the railing panel.

Two through screws pass through the light holes provided on the panel and are connected to the screw holes provided on the vertical connecting plate.

[0006] The aforementioned repair and reinforcement device for broken and aged bridge railings has side plates on both sides of the inner panel, and U-shaped notches with openings from the outside are provided on both side plates. The U-shaped notches are used to hold the fixing rods connecting the posts and the side railings.

[0007] The repair and reinforcement device for the fractured and aged bridge railing, when a cement step is provided at the bottom of the column, the lower part of the inner panel is connected to the outer side of the inner protruding plate, and a vertical plate is provided at the lower inner side of the inner protruding plate, with the lower end of the vertical plate fixedly connected to the outer side of the fixing plate A.

[0008] The aforementioned repair and reinforcement device for fractured and aged bridge railings includes an array of fixing holes A on the fixing plate A and blind holes on the sidewalk. Quick-drying adhesive is poured into each cleaned blind hole, and cement screws of the same number as fixing holes A are passed through fixing holes A and fixedly connected to the blind holes on the sidewalk above the cap beam.

[0009] The aforementioned repair and reinforcement device for fractured and aged bridge railings has multiple connecting holes B on the side plates near the outer edge of the inner panel of the U-shaped plate structure. Multiple connecting holes A are also provided on the outer bending plates on both sides of the outer baffle A. The two outer bending plates of the outer baffle A are located between the two side plates. Multiple screws pass through the multiple connecting holes B on the two side plates and the multiple connecting holes A on the two outer bending plates, and are then locked by nuts.

[0010] The aforementioned repair and reinforcement device for fractured and aged bridge railings has beveled angles between the inner panel and the two side panels.

[0011] The aforementioned repair and reinforcement device for fractured and aged bridge railings has multiple fixing holes B at the lower part of the outer baffle A and blind holes on the outer side of the cap beam. Quick-drying adhesive is poured into each cleaned blind hole, and cement screws of the same number as fixing holes B are passed through fixing holes B and fixedly connected to the blind holes on the outer side of the cap beam.

[0012] If there is a difference between the outer protruding surface of the cap beam and the outer surface of the column in the aforementioned repair and reinforcement device for the fractured and aged bridge railing, an inclined connecting plate is set in the middle of the outer baffle A, and the inner surface of the outer baffle A and the outer surface of the cap beam are closely fitted by the inclined connecting plate.

[0013] The aforementioned repair and reinforcement device for fractured and aged bridge railings has an outer support plate whose lower end is connected to the outer end of an upper horizontal plate. The inner end of the upper horizontal plate has an inclined surface, the lower part of which is fixedly connected to a vertical connecting plate.
