Description

Technical Field

[0001] This utility model relates to the field of bridge engineering construction, specifically to a bridge construction protection device for safety protection during construction near the edge of a bridge. Background Technology

[0002] In bridge construction, the edge construction of adjacent bridge decks (such as guardrail pouring and embedded part installation) is a crucial step in ensuring the structural safety and functionality of the bridge. In existing technologies, when constructing the edge areas of closely spaced adjacent bridge decks, the work surface is located in a suspended position outside the bridge deck, requiring construction workers to be hoisted to the work point using safety ropes for suspended operations. This traditional construction method has the following drawbacks:

[0003] Poor work comfort: Construction workers are in a suspended state for a long time, and their bodies are restrained by safety ropes, which can easily cause fatigue and discomfort, affecting construction efficiency.

[0004] Limited operational flexibility: The range of personnel movement is fixed when the equipment is hoisted, making it difficult to perform large-scale movements or complex operations, especially making it impossible to carry out simultaneous construction on the edges of the bridge decks on both sides.

[0005] Therefore, there is an urgent need for a protective device that can provide a stable working platform, support flexible movement of the adjacent area, and simultaneously cover the construction needs of both sides of the bridge deck, in order to overcome the limitations of the existing suspended construction method and improve the safety, convenience, and efficiency of bridge adjacent construction. Utility Model Content

[0006] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a bridge construction protection device for safety protection during construction at the edge of a bridge, which can provide a stable working platform, support flexible movement of the edge area, and simultaneously cover the construction needs of both sides of the bridge deck.

[0007] This utility model is implemented as follows: a bridge construction protection device is constructed, characterized in that: the device includes two sets of bearing seats near the bridge deck and the bridge edge, and a bearing plate that can be movably inserted between the two sets of bearing seats; the two sets of bearing seats each have a cavity inside; the bearing plate has multiple through-holes A, and the bearing seat has multiple through-holes B, and the through-holes B and through-holes A can be aligned; after the two ends of the bearing plate are movably placed in the cavity, long bolts are inserted into the through-holes A along the through-holes B to fix the bearing plate in the cavity;

[0008] A curved support is fixed to the lower side of the bearing seat, and an upper traveling roller and a side traveling roller are respectively installed at the upper and middle positions of the curved support. When the bearing seat is hoisted on the bridge deck and the side of the bridge, the upper traveling roller and the side traveling roller correspond exactly to the upper end face and the side face of the bridge deck and the side face of the bridge, respectively. The whole consisting of the curved support, the upper traveling roller and the side traveling roller can just form a limiting support for the bearing seat on the bridge deck and the side of the bridge. At the same time, when an external traction is applied, the whole device can move and travel under the action of the upper traveling roller and the side traveling roller.

[0009] According to the bridge construction protection device described in this application, the device is characterized in that: a lifting ring is installed on the side of the bearing seat; the lifting ring facilitates the hoisting of the device to the middle space between the adjacent bridge decks on both sides; in specific implementation, the lifting ring can also be used to hook and install ropes.

[0010] According to the bridge construction protection device described in this application, the bearing plate is a steel plate of moderate thickness, and the bending support is a metal support.

[0011] According to the bridge construction protection device described in this application, the bearing seat has an internal threaded positioning hole at the middle of its outer end, and an external threaded positioning rod that can be manually tightened and loosened is inserted into the internal threaded positioning hole. As the external threaded positioning rod is tightened, its bottom end contacts and abuts against the upper end surface of the bridge deck and the bridge edge, thereby locking the bearing seat on the bridge deck and preventing it from moving arbitrarily.

It offers a stable working platform, supports flexible movement in the edge area, and can simultaneously cover the construction needs of both sides of the bridge deck.

[0014] Enhanced construction flexibility and efficiency: The device achieves smooth movement along the bridge edge through upper and side traveling rollers, covering the entire construction area between adjacent bridge decks, and can simultaneously work on both sides of the edge, greatly reducing process changeover time.

[0015] Strong structural stability and adaptability: The combined design of the bending support, upper traveling roller and side traveling roller forms a three-dimensional limiting support for the bridge side, ensuring the stability of the device under movement and load-bearing conditions; the long bolt connection structure between the bearing plate and the bearing seat can flexibly adjust the platform length according to the bridge deck spacing.

[0022] The following will be combined with the appendix Figures 1-5 This utility model will be described in detail, and the technical solutions in the embodiments of this utility model will be clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0023] This utility model provides a bridge construction protection device, such as... Figures 1-4 As shown, it can be implemented in the following manner;

[0024] The device includes two sets of support seats 2 near the bridge deck edge 1, and a support plate 3 that can be movably inserted between the two sets of support seats 2; the two sets of support seats 2 each have a cavity 2-1 inside.

[0025] The support plate 3 has multiple through-holes A3-1, and the support seat 2 has multiple through-holes B2-2. The through-holes B2-2 and the through-holes A3-1 can be aligned. After the two ends of the support plate 3 are movably placed in the cavity 2-1, the support plate 3 is fixed in the cavity 2-1 by inserting long bolts 4 through the through-holes B2-2 into the through-holes A3-1.

[0026] A curved bracket 5 is fixed to the lower side of the bearing seat 2. An upper traveling roller 6 and a side traveling roller 7 are respectively installed at the upper and middle positions of the curved bracket 5. When the bearing seat 2 is suspended on the bridge deck edge 1, the upper traveling roller 6 and the side traveling roller 7 correspond exactly to the upper end face and the side face of the bridge deck edge 1, respectively. The whole consisting of the curved bracket 5, the upper traveling roller 6 and the side traveling roller 7 can just form a limiting support for the bearing seat 2 on the bridge deck edge 1. At the same time, when an external traction is applied, the whole device can move and travel under the action of the upper traveling roller 6 and the side traveling roller 7.

[0027] The side of the bearing seat 2 is equipped with a lifting ring 8; the lifting ring 8 facilitates the hoisting of the device to the middle space 9 between the two bridge panels. In specific implementation, the lifting ring 8 can also be used to hang the installation rope.

[0028] The bearing plate 3 is a steel plate of moderate thickness; the bending bracket 5 is a metal bracket.

[0029] The bearing seat 2 has an internal threaded positioning hole 10 at the middle of its outer end. An external threaded positioning rod 2-3, which can be manually tightened and loosened, is inserted into the internal threaded positioning hole 10. As the external threaded positioning rod 2-3 is tightened, its bottom end contacts and abuts against the upper end surface of the bridge deck edge 1, thereby locking the bearing seat 2 on the bridge deck edge 1 and preventing it from moving at will. After loosening the external threaded positioning rod 2-3, the bearing seat 2 can move.

[0030] This application addresses bridge edge construction work on two closely spaced adjacent bridge decks, specifically for safety protection during edge construction. Edge construction involves working on the immediate perimeter of the bridge deck, such as creating guardrails. Currently, for adjacent bridge decks, workers must wear safety ropes and be suspended outside the deck to operate, which is uncomfortable for extended periods and restricts their movement. This application provides a bridge construction safety device. After assembly, the device is suspended to the intermediate space (9) between adjacent bridge decks. Workers, wearing safety ropes, can stand on the device to perform edge operations, improving the constraints and inconvenience of suspension. Furthermore, the device allows for movement along the intermediate space (9), increasing flexibility and convenience for edge construction. Therefore, this device is suitable for construction and protection of adjacent bridge deck edges, allowing simultaneous construction on both sides, thus facilitating both construction and protection.

[0031] The specific implementation process of this application will be described in detail below;

[0032] Device assembly stage

[0033] Connection between the bearing plate and the bearing seat: According to the size of the construction space, insert both ends of the bearing plate 3 into the cavities 2-1 of the two sets of bearing seats 2 respectively. Adjust the extension length of the bearing plate 3 according to the spacing of the adjacent bridge decks so that the through connection hole B2-2 on the bearing seat 2 is aligned with the through connection hole A3-1 on the bearing plate 3. Then, pass the long bolt 4 through the aligned connection hole and tighten it to form the main body of the working platform spanning the middle space 9.

[0034] Inspection of the traveling components: Confirm the welding and fixing strength between the curved bracket 5 (metal material) and the lower side of the bearing seat 2. Check the rotation flexibility of the upper traveling roller 6 and the side traveling roller 7 at the upper and middle installation positions of the curved bracket 5, and ensure that the roller rims are compatible with the upper end and side contours of the bridge deck edge 1.

[0035] hoisting and positioning stage

[0036] Lifting point connection: Use lifting equipment to hook the lifting ring 8 on the side of the bearing seat 2, and lift the entire device smoothly to the middle space 9 of the bridge deck on both sides through the lifting ring 8. Then turn the external thread positioning rod 2-3 to lock the position of the bearing seat 2 at a certain point (construction site) on the bridge deck edge 1 to prevent it from moving at will.

[0037] Limiting support installation: After the device is hoisted into place, the upper traveling roller 6 of the bending bracket 5 is attached to the upper end surface of the bridge panel and the side traveling roller 7 is attached to the side surface of the bridge panel and the side surface of the bridge panel, forming a "top-side" two-way limiting support structure to ensure that the bearing seat 2 is stably erected on the adjacent two sides of the bridge.

[0038] Construction operation stage

[0039] Personnel safety protection: Construction workers stand on the bearing plate 3 (a steel plate of moderate thickness) and can attach safety ropes to the lifting ring 8 or the preset safety rope fixing point to form a double safety guarantee.

[0040] Construction at the edge: Construction workers can simultaneously carry out work such as pouring protective railings and installing embedded parts at the edge of the bridge deck on both sides on the bearing plate 3. During the operation, the device can be driven to move along the bridge edge by an external traction device (such as a hand-operated hoist or mechanical traction). Under the rolling action of the upper traveling roller 6 and the side traveling roller 7, the device moves smoothly along the length of the bridge deck edge 1, achieving continuous coverage of the construction area.

[0041] Disassembly and turnover stage

[0042] After construction is completed, the entire device is hoisted and removed. The long bolts 4 are loosened, and the bearing plate 3 is pulled out from the cavity 2-1 of the bearing seat 2. The main body of the device is disassembled. Each component is hoisted to the ground using the lifting rings 8, cleaned and inspected, and then stored for reuse in subsequent similar bridge edge construction scenarios.

[0043] The social value brought about by this application is:

[0044] Ensuring the safety of construction workers: This device provides a stable standing and operating platform for workers working near the edge of the bridge, changing the traditional suspended operation method that relies solely on safety ropes.

[0046] Reducing the social impact of construction accidents: Construction safety accidents not only cause casualties and family tragedies, but may also trigger negative public opinion. This device, by improving construction safety, can effectively reduce social problems caused by bridge-side construction accidents and maintain social harmony and stability.

[0047] Improving the level of civilized construction in engineering projects: The use of the device makes construction near the bridge edge more standardized and orderly, avoiding the chaos that may occur in traditional hoisting operations, which helps to improve the overall civilized construction image of bridge engineering projects and meets the requirements of modern engineering construction for civilized construction.

[0048] The economic benefits brought about by this application are:

[0049] Reduced construction costs: On the one hand, construction workers can work standing on the equipment, which improves their comfort and reduces inefficiency caused by fatigue, thereby speeding up the construction progress, shortening the construction period, and reducing labor costs; on the other hand, the equipment can be reused, which reduces material consumption and the costs of building and dismantling compared to traditional temporary protective measures such as scaffolding.

[0050] Reduced economic losses from accidents: This device can significantly reduce the incidence of construction accidents and avoid huge economic losses caused by accidents, such as compensation for personal injury, equipment damage and repair, and project shutdowns.

[0051] Improved construction efficiency: The device can move along the construction area, increasing construction flexibility and enabling simultaneous construction on the edges of both sides of the bridge deck. This reduces process changeover time, effectively increases the amount of construction completed per unit time, and thus improves the overall construction efficiency of the bridge project, allowing the project to be put into use and generate benefits earlier.

[0052] Enhancing market competitiveness: For construction companies, adopting this safe and efficient protective device can improve their construction technology and safety management capabilities, giving them a greater advantage in project bidding, helping to expand market business, and increasing corporate economic benefits.
