Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of crash barriers, specifically to a temporary crash barrier for municipal bridge construction. Background Technology

[0002] In the field of municipal bridge construction, temporary crash barriers are key facilities for ensuring construction safety, and their portability and crashworthiness directly affect project efficiency and personnel safety. However, traditional cement and metal barriers have significant technical bottlenecks in practical applications, making it difficult to meet the dynamic protection needs of bridge construction.

[0003] While traditional concrete guardrails offer some impact resistance, their high material density and individual weight (typically hundreds of kilograms) necessitate the use of heavy machinery like cranes or forklifts for transportation. Furthermore, installation requires multiple people working together to position the guardrails, making handling extremely difficult, especially in high-altitude bridge work or confined construction areas. A single move can take several hours, severely hindering construction progress. Additionally, concrete guardrails lack a cushioning structure, allowing the impact force to be directly transferred to the foundation upon collision, easily leading to cracking or overturning, resulting in insufficient protective reliability.

[0004] While metal guardrails are lighter than concrete guardrails, they mostly use rigid frame structures, and their impact resistance depends on the material strength. When subjected to vehicle or mechanical collisions, the guardrails are prone to plastic deformation and lack energy-absorbing designs, meaning that collision energy cannot be effectively dissipated, potentially causing secondary safety hazards. Furthermore, existing metal guardrails are mostly fixed structures, requiring bolts to connect each component during assembly and disassembly. This is cumbersome and prone to component loss during frequent site adjustments in bridge construction, making them unsuitable for rapid deployment in temporary protection scenarios.

[0005] As municipal bridge engineering develops towards modularization and efficiency, the shortcomings of traditional guardrails in terms of portability and impact resistance are becoming increasingly prominent. For example, in the construction of bridge expansion joints or temporary lane isolation scenarios, there is an urgent need for a temporary guardrail that can be quickly assembled and disassembled, and is both lightweight and has high buffering performance, in order to solve the industry pain points of cement guardrails being "heavy and bulky" and metal guardrails being "brittle and weak," and to improve the flexibility and reliability of construction safety protection. Utility Model Content

[0006] To overcome the above-mentioned defects, the embodiments of this disclosure provide a temporary crash barrier for municipal bridge construction, which solves the technical problem that existing cement barriers and metal barriers are relatively heavy and bulky, difficult to carry, and although they have a protective effect, they do not have the function of buffering and preventing collisions.

[0007] According to one aspect, at least one embodiment of this disclosure provides a temporary crash barrier for municipal bridge construction, comprising:

[0008] Several upright panels and a front guard, wherein the front guard is disposed on the outside of the upright panels;

[0009] A stabilizing component is disposed between the upright plate and the front guard;

[0010] A docking assembly, wherein the docking assembly is disposed on the outer side of the upright plate;

[0011] A buffer protection assembly, wherein the buffer protection assembly is disposed in the front windshield;

[0012] The buffer protection assembly includes a buffer layer disposed on the surface of the front bumper, and a buffer cavity is formed inside the front bumper, with a plurality of support springs disposed inside the buffer cavity.

[0013] As a further technical solution, the stabilizing component includes several water tanks, which are respectively fixed between a pair of adjacent upright plates. A water inlet trough is provided on the top of the water tank, and a cover plate is installed on the water inlet trough.

[0014] As a further technical solution, a pair of internally threaded blocks are provided on the top of the front guard, a pair of bolts are inserted into the cover plate, the bolts are screwed into the internally threaded blocks, and connecting plates are vertically slidably inserted between several of the upright plates.

[0015] As a further technical solution, the front guard is laterally slidably inserted into the surface of the connecting plate, a pair of fixed posts are provided on the outer end face of the upright plate, and connecting rods are fitted on several fixed posts at the same horizontal height, and a drain outlet is provided at the lower end of the side surface of the water tank.

[0016] As a further technical solution, the docking assembly includes several sleeves, all of which are fixed to the side surface of the upright plate. A connecting rod is inserted into each sleeve, and the connecting rod is fixedly connected to the sleeve by screws.

[0017] As a further technical solution, the water tank adopts a foldable rubber material structure.

[0018] As a further technical solution, the cross-section of the connection between the connecting plate and the upright plate, as well as the connection between the front guard and the connecting plate, is T-shaped.

[0019] As a further technical solution, the water tank and one side surface of the upright plate are inclined structural surfaces.

[0020] The beneficial effects of the embodiments disclosed herein are as follows:

[0021] 1. In this disclosure, the buffer protection component forms a double buffer structure through the buffer layer on the front guard surface and the support spring in the internal buffer cavity. When impacted, the buffer layer first absorbs part of the impact force through elastic deformation. Then, the support spring in the buffer cavity is compressed, converting kinetic energy into elastic potential energy. The energy is gradually released through the spring's rebound, avoiding rigid collisions that could damage or overturn the guardrail. This design effectively reduces the damage to the guardrail and the impacting object, improves the reliability of protection, and solves the safety hazard problem caused by the lack of buffer in traditional guardrails.

[0022] 2. In this disclosure, the stabilizing component utilizes a foldable rubber water tank to inject a medium, increasing the weight of the guardrail and enhancing its anti-overturning ability. The water tank and the uprights form a rigid triangular support structure through bolts and connecting plates, enhancing overall stability. The connecting rods and fixing columns between the uprights further strengthen the lateral connection, adapting to different construction environments. The foldable design of the water tank facilitates transportation. When in use, water or sand is added to increase the weight, and when transferred, the tank is emptied to reduce the burden. This solves the problems of the bulkiness of cement guardrails and the insufficient stability of metal guardrails, achieving a balance between portability and stability. Attached Figure Description

[0028] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0029] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0030] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0031] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0033] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0034] like Figures 1-3 As shown, it illustrates a temporary crash barrier for municipal bridge construction in one embodiment of this disclosure, comprising:

[0035] Several upright plates 1 and a front guard 2, wherein the front guard 2 is disposed on the outside of the upright plates 1;

[0036] Stabilizing component 4, which is disposed between the upright plate 1 and the front guard 2;

[0037] The docking component 5 is disposed on the outer side of the upright plate 1;

[0038] A buffer protection component 3 is disposed in the front bumper 2;

[0039] The buffer protection component 3 includes a buffer layer 3-1, which is disposed on the surface of the front guard 2. A buffer cavity 3-2 is provided inside the front guard 2, and a plurality of support springs 3-3 are disposed inside the buffer cavity 3-2.

[0040] In some examples, a buffer protection component 3 is designed to reduce the impact force during a vehicle collision. This component has a buffer layer 3-1 on the surface of the front guard 2 as the first layer of protection, which is made of highly elastic rubber material and can absorb the kinetic energy in the initial stage of the impact. The buffer cavity 3-2 inside the front guard 2 constitutes the second layer of protection. The support springs 3-3, which are evenly distributed in the cavity, are connected at one end to the buffer layer 3-1 and fixed at the other end to the inner wall of the guard. When impacted, the buffer layer 3-1 is compressed and indented, which causes the spring to compress and deform, converting the impact force into the elastic potential energy of the spring. The kinetic energy is gradually offset by the reciprocating rebound of the spring, avoiding structural damage caused by rigid collision.

[0041] The combined design of the buffer layer 3-1 and the support spring 3-3 enables the buffer protection component 3 to effectively buffer and unload force when an impact occurs, reducing the degree of damage to the guardrail and vehicle, and improving the safety protection performance of the temporary crash barrier.

[0042] like Figures 1-3 As shown in the figure, the stabilizing component 4 in this embodiment includes several water tanks 4-1, which are fixed between a pair of adjacent upright plates 1. A water inlet trough 4-2 is provided on the top of each water tank 4-1, and a cover plate 4-3 is installed on the water inlet trough 4-2. A pair of internally threaded blocks 4-4 are provided on the top of the front guard 2, and a pair of bolts 4-5 are inserted into the cover plate 4-3. The bolts 4-5 are screwed into the internally threaded blocks 4-4. A connecting plate 4-6 is vertically slidably inserted between several upright plates 1, and the front guard 2 is laterally slidably inserted into the surface of the connecting plate 4-6. A pair of fixing posts 4-7 are provided on the outer end face of each upright plate 1, and connecting rods 4-8 are fitted on several fixing posts 4-7 at the same horizontal height. A drain outlet 4-9 is provided at the lower end of the side surface of each water tank 4-1.

[0043] In some examples, to enhance the stability and anti-overturning capability of temporary guardrails, a stabilizing component 4 is designed. This component is centered on a water tank 4-1 between adjacent uprights 1. The top water inlet 4-2 can be filled with clean water or sand and gravel, increasing the overall stability of the guardrail by increasing its own weight. The cover plate 4-3 on the water inlet 4-2 is fixedly connected to the internally threaded block 4-4 on the top of the front guard 2 by bolts 4-5, which not only prevents foreign objects from falling into the water tank 4-1, but also rigidly connects the front guard 2 to the uprights 1, forming a stable triangular support structure. The connecting plate 4-6, which is vertically slidably inserted between the uprights 1, and the front guard 2, which is laterally slidably inserted onto the connecting plate 4-6, achieve quick positioning with the uprights 1. The fixing post 4-7 on the outer end face of the uprights 1 is fitted with the connecting rod 4-8 to enhance the overall wind load and impact resistance of the guardrail. The drain outlet 4-9 on the side surface of the water tank 4-1 can quickly empty the internal medium when the guardrail is moved, reducing weight and facilitating handling.

[0044] Through the weight-increasing design of water tank 4-1, the rigid connection of bolt 4-5, the height adjustment of connecting plate 4-6, and the lateral reinforcement of connecting rod 4-8, the stabilizing component 4 achieves the function of increasing the supporting weight by filling medium and adapting to different construction environments, ensuring the stability and reliability of the temporary guardrail during bridge construction.

[0045] like Figures 1-3 As shown in the figure, the docking assembly 5 in this embodiment includes a plurality of sleeves 5-1, all of which are fixed to the side surface of the upright plate 1. A connecting rod 5-2 is inserted into the sleeve 5-1, and the connecting rod 5-2 is fixedly connected to the sleeve 5-1 by screws.

[0046] In some examples, a connecting assembly 5 is designed to enable rapid splicing and continuous arrangement of multiple guardrail sets. This assembly uses a sleeve 5-1 fixed to the side surface of the upright plate 1 as the connection reference. Connecting rods 5-2 are inserted into the sleeves 5-1 of adjacent upright plates 1. The connecting rods 5-2 are fastened to the sleeves 5-1 with screws, allowing multiple guardrail sets to be connected end to end to form a long-distance protective structure. The sleeves 5-1 are made of high-strength steel pipes with anti-slip textures on the inner wall to enhance friction with the connecting rods 5-2. The connecting rods 5-2 have external threads at both ends. After aligning with the screw holes on the side wall of the sleeves 5-1, screws are screwed in to lock the connection position. The assembly and disassembly are convenient and the connection is firm. This modular connecting design allows for flexible combination of guardrail lengths according to the actual needs of bridge construction, suitable for bridge decks or curved areas of different widths. At the same time, it ensures that the overall stress of the spliced ​​guardrail is uniform, avoiding breakage or displacement at the connection point, and providing a continuous and complete safety barrier for bridge construction.

[0047] For example, such as Figure 2 As shown, the water tank 4-1 adopts a foldable rubber material structure.

[0048] In some examples, the rubber material allows for stretching and compression, reducing the overall size of the structure during transport and making it more convenient to carry.

[0049] For example, such as Figure 1 As shown, the cross-sections of the connections between the connecting plate 4-6 and the upright plate 1, as well as between the front guard 2 and the connecting plate 4-6, are all T-shaped.

[0050] In some examples, the T-shaped structure prevents the pieces from coming loose after being joined, making the connection more secure.

[0051] For example, such as Figure 2 As shown, the water tank 4-1 and one side surface of the vertical plate 1 are inclined structural surfaces.

[0052] In some examples, tilting the structural surfaces can increase stability and prevent tipping over.

[0053] In actual use: Place the upright plate 1 vertically, stretch and unfold the water tank 4-1, and slide the front guard 2 horizontally onto the outside of the upright plate 1 via the connecting plate 4-6. Insert the connecting plate 4-6 vertically between adjacent upright plates 1 and fix it. Fix the water tank 4-1 between adjacent upright plates 1 with the water inlet trough 4-2 facing upwards. Install the fixing post 4-7 on the outer end face of the upright plate 1. Fit the connecting rod 4-8 onto the fixing post 4-7 of the same height. When connecting, insert the connecting rod 5-2 into the sleeve 5-1 of the adjacent upright plate 1 and fix it with screws. Install the buffer layer 3-1 on the surface of the front guard 2. Connect the two ends of the support spring 3-3 in the buffer cavity 3-2 to the buffer layer 3-1 and the inner wall of the front guard 2 respectively. During use, inject the medium into the water tank 4-1 through the water inlet trough 4-2. Then, connect the cover plate 4-3 to the internally threaded block 4-4 at the top of the front guard 2 via bolts 4-5 to provide support and protection. The drain port 4-9 is used to drain the medium. The front guard 2 is connected via T... The character-shaped structure is slidably connected to the connecting plate 4-6, and the inclined surfaces of the upright plate 1 and the water tank 4-1 enhance stability.
