Description

Technical Field

[0001] This utility model belongs to the field of construction safety technology, specifically relating to a bridge construction safety guardrail. Background Technology

[0002] In the field of bridge construction, safety guardrails are an indispensable key facility to ensure the safety of construction workers and prevent falls from heights. Their design and application are directly related to the life safety of personnel on the construction site and the smooth progress of the project. However, despite the undeniable importance of safety guardrails, the existing bridge construction safety guardrails still show significant deficiencies in impact resistance, which has become a technical problem that urgently needs to be solved.

[0003] Specifically, the bridge construction safety guardrails currently on the market generally have weak impact resistance. During bridge construction, due to the complexity and uncertainty of the construction environment, safety guardrails may face a variety of unexpected impacts, including but not limited to accidental collisions with construction vehicles, misoperation of heavy construction equipment, and wind pressure under extreme weather conditions. These external impacts are often huge and difficult to predict, posing a severe challenge to the structural strength and stability of the guardrails.

[0004] When subjected to external impacts, guardrails are prone to deformation, breakage, or even complete collapse, which severely weakens their intended protective function. This not only fails to effectively protect the safety of construction workers but may also trigger secondary disasters, such as falling objects or equipment damage, further exacerbating the risks at the construction site.

[0005] Therefore, there is an urgent need for a safety barrier that can withstand impacts. Utility Model Content

[0006] To address the aforementioned problems in the existing technology, this utility model provides a bridge construction safety guardrail that solves the problem that the guardrail is prone to deformation, breakage, or even complete collapse when encountering external impacts, thereby severely weakening its intended protective function.

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0008] A bridge construction safety guardrail includes a mounting base, support columns, a protective plate, and a first elastic connector; a plurality of the support columns are spaced apart on the mounting base, and the protective plate is disposed between any two adjacent support columns; the protective plate is provided with a plurality of elastic connecting strips, each of which is fixedly connected to the first elastic connector, the first elastic connector being used to elastically connect the protective plate to the support columns.

[0009] Preferably, the mounting base includes a horizontal mounting base and a vertical mounting base. There are multiple horizontal mounting bases, which are evenly distributed on both sides of the vertical mounting base. One side of the horizontal mounting base is fixedly connected to the vertical mounting base, and the other side of the horizontal mounting base is fixedly connected to the protective plate.

[0010] Preferably, the longitudinal mounting base is disposed on the ground, the longitudinal mounting base is provided with a groove, and the support column is installed in the groove.

[0011] Preferably, it further includes a horizontal support rod fixedly installed at the top of the support column, the horizontal support rod being horizontal with the horizontal mounting base; the horizontal support rod is provided with a plurality of second elastic connectors, all of which are connected to the protective plate.

[0012] Preferably, the transverse support rod has multiple hollow sections, and each hollow section contains a monitoring device. The monitoring device faces the construction site and is used to detect the stress state of the protective plate.

[0013] Preferably, it also includes an alarm device, wherein the transverse support rod has multiple bearing grooves, the alarm device is located in the bearing grooves, and the alarm device is electrically connected to the monitoring equipment for issuing an alarm.

[0014] The beneficial effects of this utility model are as follows:

[0015] The first elastic connector and its connected elastic connecting strip of this application can absorb and disperse part of the impact energy, and the first elastic connector can deform without breaking immediately, thereby effectively mitigating the damage to the overall structure of the guardrail caused by the impact. After the external impact ends, the first elastic connector and the elastic connecting strip can recover to their pre-deformation state due to their elasticity, allowing the guardrail to quickly return to its initial protective state, ensuring continuous and effective protection, enhancing the guardrail's impact resistance, and providing a stronger impact-resistant guardrail that provides higher safety assurance for bridge construction sites, reducing the risk of safety accidents caused by accidental impacts, and protecting the life and property safety of construction personnel.

[0022] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0023] like Figures 1-4 As shown, a bridge construction safety guardrail includes a mounting base 100, support columns 200, a protective plate, and a first elastic connector 800; a plurality of support columns 200 are spaced apart on the mounting base 100, and the protective plate is disposed between any two adjacent support columns 200; the guardrail plate 300 is provided with a plurality of elastic connecting strips, each of which is fixedly connected to the first elastic connector 800, which is used to elastically connect the guardrail to the support columns 200;

[0024] The support columns 200 are securely installed on the bridge using mounting bases 100. The support columns 200 are spaced apart, forming a support frame for the protective plate. This spaced arrangement reduces the overall weight of the protective structure. The protective plate is positioned between adjacent support columns 200, providing direct protection. Importantly, the protective plate is equipped with multiple elastic connecting strips, which are elastically connected to the support columns 200 via first elastic connectors 800. This allows the protective plate some displacement space when subjected to external impact, rather than directly bearing the impact force. When an external impact acts on the protective plate, the first elastic connector 800 and its connected elastic connecting strips can... It can absorb and disperse some of the impact energy. Due to the properties of the elastic material, the first elastic connector 800 can deform without breaking immediately, thus effectively mitigating the damage to the overall structure of the guardrail. After the external impact ends, the first elastic connector 800 and the elastic connecting strip can recover to their pre-deformation state due to their elasticity, allowing the guardrail to quickly return to its initial protective state, ensuring continuous and effective protection, enhancing the guardrail's impact resistance. The guardrail with stronger impact resistance provides higher safety assurance for bridge construction sites, reduces the risk of safety accidents caused by accidental impacts, and protects the life and property safety of construction personnel.

[0025] In one embodiment, the mounting base 100 includes a horizontal mounting base 101 and a vertical mounting base 102. There are multiple horizontal mounting bases 101, which are evenly distributed on both sides of the vertical mounting base 102. One side of each horizontal mounting base 101 is fixedly connected to the vertical mounting base 102, and the other side is fixedly connected to the guardrail. The vertical mounting base 102 serves as the main support structure, responsible for bearing the vertical load from the guardrail and its support column 200. The horizontal mounting bases 101 achieve a reliable connection with the guardrail, simplifying the installation process and improving the strength and durability of the connection points. The even distribution and adjustable number of horizontal mounting bases 101 can adapt to guardrails of different widths and lengths. Simultaneously, the L-shaped structural design allows the horizontal mounting bases 101 to flexibly adapt to different terrains and installation conditions, improving the flexibility and adaptability of guardrail installation.

[0026] In one embodiment, a longitudinal mounting base 102 is disposed on the ground and has a groove. A support column 200 is installed in the groove. The longitudinal mounting base 102 serves as the main support structure of the guardrail and is securely installed on the ground. The ground can be a bridge deck, a construction platform, or other stable foundation structure. The design of the longitudinal mounting base 102 ensures that it can withstand all vertical and horizontal loads that may be applied to the guardrail and above it. Due to the tight fit between the support column 200 and the groove, the installation process becomes simple and efficient. Construction workers only need to align the support column 200 with the groove and gently push it in to complete the initial installation. Similarly, when it is necessary to disassemble or move the guardrail, the support column 200 can simply be pulled out of the groove without the need for complicated tools or equipment.

[0027] In one embodiment, a transverse support rod 400 is also included, fixedly mounted on the top of the support column 200 and level with the transverse mounting base 101. This design forms an additional horizontal support structure at the top of the guardrail, enhancing the overall rigidity and stability of the guardrail. When an external impact acts on the guardrail, the transverse support rod 400 can disperse and absorb part of the impact force, reducing the direct impact on the support column 200 and the mounting base 100. Multiple second elastic connectors 900 are provided on the transverse support rod 400, connected to the guardrail. When the guardrail is subjected to an external impact, the second elastic connectors 900 can deform, absorbing and dispersing the impact energy, further mitigating damage to the overall structure of the guardrail. Simultaneously, the guardrail has a certain displacement space when impacted, thereby improving its impact resistance and durability.

[0028] In one embodiment, the horizontal support rod 400 has multiple hollow sections, each containing a monitoring device 700 facing the construction site. The monitoring device 700 is used to detect the stress state of the protective barrier. Furthermore, the monitoring device 700 monitors the impact on the guardrail. It integrates sensors such as accelerometers and pressure sensors, enabling real-time monitoring of the impact force, direction, and duration. When the guardrail is subjected to an external impact, the sensors immediately detect these changes. The impact data collected by the monitoring device 700 is transmitted wirelessly or via wired connection to the central control system. The central control system processes and analyzes the data to determine if the impact exceeds a preset safety threshold. If the impact force is too great or the duration is too long, the system issues a warning signal to alert construction personnel and prompt them to take appropriate measures. The monitoring device 700 can promptly detect potential safety hazards and issue warning signals, thereby effectively preventing accidents and improving construction safety.

[0029] In one embodiment, an alarm device 600 is also included. The transverse support rod 400 has multiple bearing grooves, and the alarm device 600 is located in the bearing grooves. The alarm device 600 is electrically connected to the monitoring device 700 and is used to issue an alarm. Through real-time monitoring and timely alarm, potential safety hazards can be quickly detected and dealt with, effectively preventing accidents from occurring. Especially at night or in situations with poor visibility, the alarm device 600 can emit a clear alarm sound or light to remind construction personnel to evacuate in time or take protective measures. Furthermore, warning signs are provided on both sides of the guardrail 300, and reflective strips are provided on the upper and lower sides of the warning signs. Through the warning signs and reflective strips, relevant personnel and vehicles can be further reminded to avoid the guardrail.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
