Description

Technical Field

[0001] This utility model relates to the field of edge protection technology for cap beams, specifically a prefabricated edge protection device for cap beams. Background Technology

[0002] Edge protection devices for bridge caps refer to structures that protect the edges of bridge caps. These safety facilities protect the top edge of the cap and are designed to prevent accidental falls or collisions during construction. Such devices typically include guardrails, safety nets, and other safety features to ensure the safety of construction workers. By implementing multiple layers of protection, the risks associated with bridge cap construction are reduced, making it a key aspect of bridge engineering safety management. For example: Chinese Patent Publication No. CN220202466U discloses a prefabricated edge protection device for cap beams. It includes multiple I-beams for edge protection, arranged alternately with distribution beams at the bottom of the cap beam. Vertically fixed steel pipes are fixed to the upper parts of both ends of each I-beam, and uprights are inserted into each fixed steel pipe. The fixed steel pipes and uprights are connected by pins. An edge protection mesh is installed on the outside of the uprights at the same end of the I-beams, and the edge protection mesh is connected to the fixed steel pipes by cross-shaped U-shaped pipe clamps. This utility model has a simple structure, good protective effect, and is reusable. The prefabricated structure allows for rapid installation and dismantling, avoiding on-site welding, ensuring fire safety, preventing material waste, saving resources, and reducing construction costs.

[0003] Based on existing solutions and actual production and processing, the current edge protection devices for cap beams still have some problems, such as: When assembling the edge protection device of the cap beam, the edge protection mesh is assembled by means of pins. However, the pins may loosen or even fall off when subjected to external force or vibration, which will affect the stability and safety of use. Since the edge protection mesh is set vertically to the edge protection I-beam, the edge protection mesh may tilt. Therefore, this utility model provides a prefabricated cap beam edge protection device to solve the above-mentioned problem. Utility Model Content

[0004] The purpose of this utility model is to provide a prefabricated edge protection device for cap beams, in order to solve the problem mentioned in the background art that the edge protection device for cap beams is assembled by means of pins. Since the pins may loosen or even fall off when subjected to external force or vibration, it affects the stability and safety of use. Also, since the edge protection netting is set vertically to the I-beam for edge protection, it may cause the edge protection netting to tilt.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated cap beam edge protection device, comprising a steel beam, with an installation block connected to the middle side of its upper end, and a cap beam mold connected to the inner side of the installation block; Also includes: A fixing plate is installed on the outer side of the upper end of the steel beam, and an installation rod is connected to the outer side of the fixing plate. A guardrail is connected to the upper side of the fixing plate, and a protective mesh is provided on the inner side of the guardrail. An assembly structure is connected to the outer side of the lower end of the steel beam, and the assembly structure includes a movable plate and a connecting rod. The movable plate is installed on the outer side of the lower end of the steel beam, and a connecting rod is connected to the lower side of the movable plate. The mounting plate is installed on the inner side of the middle part of the guardrail, and a fixing rod is connected to the upper end of the mounting plate. A support structure is connected to the inner side of the lower end of the mounting plate. The support structure includes a limiting rod, a support plate, and a connecting plate. The support plate is installed on the inner side of the lower end of the mounting plate, and a connecting plate is connected to the lower side of the support plate. A limiting rod is connected to the inner side of the connecting plate.

[0006] Preferably, a mounting connecting plate is fixedly installed on the lower middle side of the cover beam mold, and a connecting positioning rod is connected to the lower middle side of the mounting connecting plate, and a limit moving rod is movably connected to the lower outer side of the mounting connecting plate.

[0007] Preferably, the support plate is inclined and the support plates are evenly distributed on the inner side of the guardrail.

[0008] Preferably, the support plate and the connecting plate are fixedly connected, and the connecting plate and the limiting rod are threadedly connected.

[0009] Preferably, the connecting positioning rod and the mounting connecting plate are engaged, and the connecting positioning rods are symmetrically distributed about the center line of the mounting connecting plate.

[0010] Preferably, the mounting connecting plate and the steel beam are interlocked, and the mounting connecting plate and the connecting positioning rod are fixedly connected.

[0011] Preferably, the movable plate and the steel beam are slidably connected, and the vertical cross-sectional shape of the movable plate is a "U" shape.

[0012] Preferably, the movable plate and the connecting rod are connected by a thread and the movable plate serves to limit the movement of the fixed plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the prefabricated cap beam edge protection device is provided with a limiting structure, which can limit the edge protection mesh, thereby assembling the edge protection mesh and the steel beam, and is provided with a support structure, which can support the edge protection mesh, thereby preventing the edge protection mesh from tilting. By installing the guardrail on the upper side of the steel beam, the guardrail drives the fixing plate to engage with the upper outer side of the steel beam. Rotating the mounting rod causes it to be threaded on the outer side of the middle of the steel beam, thus threading the mounting rod onto the outer side of the fixing plate. Then, pushing the moving plate inward causes it to slide inward on the lower side of the steel beam, thus engaging with the inner side of the fixing plate. Rotating the connecting rod causes it to be threaded on the outer side of the moving plate, thus moving the connecting rod upward and threading it onto the lower side of the steel beam, facilitating the assembly of the guardrail and the steel beam. By installing the cap beam mold on the upper side of the steel beam and the inner side of the mounting block, the cap beam mold drives the mounting connecting plate to be installed on the inner middle side of the steel beam. Then, the mounting connecting plate is engaged with the upper outer side of the connecting positioning rod. By rotating the limiting moving rod, the limiting moving rod is threadedly connected to the lower middle side of the steel beam, thereby moving the limiting moving rod upward. Then, the limiting moving rod is threadedly connected to the lower outer side of the mounting connecting plate, which facilitates the assembly between the cap beam mold and the steel beam. By installing the support plate on the inside of the guardrail, the support plate drives the connecting plate to be installed on the upper side of the steel beam, thereby allowing the support plate to drive the mounting plate to be installed in the middle of the guardrail. Rotating the fixing rod causes it to be threaded onto the upper side of the mounting plate, thus creating a threaded connection in the middle of the guardrail. Then, rotating the limiting rod causes it to be threaded onto the inside of the connecting plate, allowing the limiting rod to move downwards and eventually be threaded onto the upper side of the steel beam. This facilitates the limiting of the support plate, thereby providing support for the guardrail. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-6 This utility model provides a technical solution: a prefabricated edge protection device for a cap beam, comprising a steel beam 1, a cap beam mold 2, an installation block 3, a limiting rod 4, a guardrail 5, a support plate 6, a protective mesh 7, an installation plate 8, a fixing rod 9, a connecting positioning rod 10, an installation connecting plate 11, a limiting moving rod 12, a connecting plate 13, a fixing plate 14, an installation rod 15, a moving plate 16, and a connecting rod 17. In operation, the specific details are as follows... Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, a movable plate 16 is movably installed on the outer side of the lower end of the steel beam 1, a connecting rod 17 is movably installed on the outer side of the lower end of the movable plate 16, a fixed plate 14 is movably installed on the outer side of the upper end of the steel beam 1, an installation rod 15 is movably connected to the outer side of the fixed plate 14, a guardrail 5 is fixedly installed on the upper side of the fixed plate 14, and a protective mesh 7 is fixedly connected to the inner side of the guardrail 5. The guardrail 5 is manually placed on the upper side of the steel beam 1, causing the guardrail 5 to engage with the fixed plate 14 on the outer side of the upper end of the steel beam 1. Then, the movable plate 16 is pushed outwards, causing it to slide outwards within the steel beam 1 under the thrust, thus placing the movable plate 16 on the inner side of the lower end of the fixed plate 14. To make the connection, tighten the connecting rod 17, causing it to be threaded onto the lower outer side of the moving plate 16. This threaded connection causes the connecting rod 17 to move downwards, thus creating a threaded connection on the lower outer side of the steel beam 1. Then, tighten the mounting rod 15, causing it to be threaded onto the middle outer side of the steel beam 1. This moves the mounting rod 15 inwards, creating a threaded connection on the middle outer side of the fixing plate 14. This facilitates the installation of the guardrail 5 and the assembly of the guardrail 5 with the steel beam 1. Specific examples Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the mounting block 3 is fixedly installed on the middle side of the upper end of the steel beam 1, the cap beam mold 2 is movably installed inside the mounting block 3, the mounting connecting plate 11 is fixedly installed on the lower side of the cap beam mold 2, the connecting positioning rod 10 is fixedly installed on the middle side of the inside of the steel beam 1, and the limiting moving rod 12 is movably installed on the middle side of the lower end of the steel beam 1. By placing the cap beam mold 2 on the middle side of the upper end of the steel beam 1, the cap beam mold 2 drives the mounting connecting plate 11 to engage and install on the middle side of the inside of the steel beam 1, thereby installing the cap beam mold 2 inside the mounting block 3, and further driving the mounting connecting plate 11 to engage and install on the middle side of the steel beam 1. Plate 11 is engaged with the outer side of the connecting positioning rod 10 to position the cover beam mold 2. Tightening the limiting moving rod 12 causes the limiting moving rod 12 to be threadedly connected to the middle side of the lower end of the steel beam 1. Under the thread action between the limiting moving rod 12 and the steel beam 1, the limiting moving rod 12 moves upward, and then the limiting moving rod 12 is threadedly connected to the lower side of the mounting connecting plate 11, which facilitates the fixing of the mounting connecting plate 11 and facilitates the assembly between the steel beam 1 and the cover beam mold 2. Specific examples Figure 1 , Figure 2 and Figure 4 As shown, a mounting plate 8 is movably installed on the inner side of the middle of the guardrail 5. A fixing rod 9 is threadedly connected to the upper side of the mounting plate 8. A support plate 6 is fixedly installed on the inner side of the mounting plate 8. A connecting plate 13 is fixedly installed on the lower side of the support plate 6. A connecting plate 13 is movably installed on the inner side of the connecting plate 13. When the support plate 6 is placed on the inner side of the guardrail 5, the support plate 6 drives the connecting plate 13 to fit against the upper side of the steel beam 1, thereby causing the support plate 6 to drive the mounting plate 8 to be installed on the inner side of the middle of the guardrail 5. Tightening the fixing rod 9 causes the fixing plate 6 to fit against the upper side of the steel beam 1. The fixed rod 9 is threaded to the upper end of the mounting plate 8, so that the fixed rod 9 moves inward under the action of the thread between the fixed rod 9 and the mounting plate 8, and then the fixed rod 9 is threaded to the middle of the guardrail 5. Then the limiting rod 4 is screwed, so that the limiting rod 4 is threaded to the inner side of the connecting plate 13, and then the limiting rod 4 moves downward, and then the limiting rod 4 is threaded to the upper side of the steel beam 1, which facilitates the fixing of the support plate 6, and thus facilitates the support of the guardrail 5.
