Description

Technical Field

[0001] This application relates to the field of construction guardrail technology, and in particular to a quick-release construction guardrail for civil engineering. Background Technology

[0002] In traditional civil engineering construction, construction guardrails are widely used to ensure work safety. Common traditional construction guardrails typically use bolts or welding to connect the posts and crossbars. While these connection methods provide a relatively stable structure, they reveal many inconveniences in practical applications, severely restricting construction efficiency and economy.

[0003] First, the installation process requires specialized tools such as wrenches and welding machines, increasing the burden on construction workers. Second, the disassembly process is cumbersome and time-consuming, especially at construction sites where the guardrails need to be moved frequently, making this fixing method particularly inconvenient. Furthermore, the fixed size of traditional guardrails leads to high transportation and storage costs. Due to the lack of flexibility in the structural design of traditional guardrails, their size is fixed after installation and cannot be adjusted according to actual needs. This directly results in the guardrails occupying a large amount of space during transportation and storage, significantly increasing logistics and warehousing costs. For construction companies that need to frequently relocate or store guardrails for long periods, this is undoubtedly a considerable burden. Utility Model Content

[0004] To address the aforementioned issues, this application provides a quick-release construction guardrail for civil engineering that can be quickly assembled and disassembled without tools and effectively saves storage space.

[0005] To achieve the above objectives, this application designs a quick-release construction guardrail for civil engineering, comprising a post, a crossbar, a first connecting sleeve, a second connecting sleeve, and a connecting ring. The connecting ring is sleeved on the post, and multiple first quick-release components are spaced vertically on the outer side wall of the post. The connecting ring is detachably fixed to the post via the first quick-release components. The crossbar has a first end and a second end, the first end being pivotally connected to the connecting ring via the first connecting sleeve. One end of the second connecting sleeve is provided with a fixing hole adapted to the second end, and the other end is fixed to the connecting ring. The second end is provided with a second quick-release component, and the second end of the crossbar is detachably inserted into the second connecting sleeve via the second quick-release component.

[0006] A further option is to provide a base at the bottom of the column, the base being adapted to be fixedly installed on the ground by fasteners.

[0007] A further embodiment is that the base has a radially extending skirt with through holes, and the fastener is a bolt that passes through the through holes to fix the base to the ground.

[0008] A further option is to form a space or structure inside or above the base for accommodating counterweights.

[0009] A further option is that the first quick-release component is a pin or a resilient self-locking mechanism; wherein the resilient self-locking mechanism includes a resilient protrusion and a positioning hole provided on the outer wall of the connecting ring and adapted to the resilient protrusion; when the connecting ring is sleeved on the column, the resilient protrusion extends into the positioning hole to lock the connecting ring and the column.

[0010] A further option is that the structure of the second quick-release component is the same as that of the first quick-release component.

[0011] A further embodiment is that the elastic protrusions are arranged at equal intervals in the vertical direction.

[0012] A further option is that the first connecting sleeve and the second connecting sleeve are arranged opposite each other along the radial direction of the connecting ring.

[0013] A further embodiment is that two second connecting sleeves are provided on the connecting ring, and the axial directions of the two second connecting sleeves are perpendicular to each other.

[0014] A further embodiment is that the connecting ring has an integrally formed connecting ear, the connecting ear having a shaft hole extending radially along the connecting ring, and the first connecting sleeve having a pivot that is rotatably inserted into the shaft hole so that the first connecting sleeve and the connecting ear are pivotally connected; wherein, the crossbar can rotate between an unfolded position perpendicular to the column and a folded position parallel to the column via the first connecting sleeve.

[0015] The quick-release construction guardrail for civil engineering designed in this application, through the synergistic use of elastic quick-release components and connecting rings, eliminates the need for traditional bolts or welding fixation, enabling rapid manual installation and disassembly without any tools. This significantly shortens construction preparation and dismantling time, improving construction efficiency. Furthermore, the design of the first and second connecting sleeves allows the crossbars to be rotated and folded to a state essentially parallel to the posts after disassembly, greatly reducing the size of the guardrail after storage, significantly lowering transportation costs and storage space requirements, and facilitating handling and management.

[0019] The components include: column 10, crossbar 20, first connecting sleeve 30, pivot 31, second connecting sleeve 40, fixing hole 41, connecting ring 50, connecting ear 51, first quick release piece 60, elastic protrusion 61, positioning hole 62, second quick release piece 70, base 80, skirt 81, and through hole 82. Detailed Implementation

[0020] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0021] like Figures 1 to 3 As shown, the quick-release construction guardrail for civil engineering designed in this application is mainly composed of a post 10, a horizontal bar 20, a first connecting sleeve 30, a second connecting sleeve 40, and a connecting ring 50.

[0022] Specifically, the connecting ring 50 has a ring-shaped structure and can be made of metal materials such as steel or aluminum alloy to ensure sufficient strength and rigidity. The connecting ring 50 is sleeved on the outside of the post 10, which is preferably made of steel pipe or aluminum alloy pipe, serving as the vertical support structure of the guardrail. To achieve quick and detachable fixing between the connecting ring 50 and the post 10, multiple first quick-release pieces 60 are arranged at intervals along the vertical direction on the outer side wall of the post 10.

[0023] In this embodiment, the first quick-release member 60 is a pin or a resilient self-locking mechanism, and the connecting ring 50 is detachably fixed to the column 10 via the first quick-release member 60. In a specific example, such as Figure 1 , Figure 2 As shown, the elastic self-locking mechanism includes an elastic protrusion 61 and a positioning hole 62 formed on the outer wall of the connecting ring 50 and adapted to the elastic protrusion 61. When the connecting ring 50 is fitted onto the column 10, the elastic protrusion 61 extends into the positioning hole 62 and automatically locks in place, thus locking the connecting ring 50 and the column 10. For disassembly, simply press the elastic protrusion 61 to disengage it from the positioning hole 62, and the connecting ring 50 can be easily removed from the column 10 or its position on the column 10 can be moved. The operation is simple and quick, requiring no tools. In this embodiment, three elastic protrusions 61 are equidistantly spaced in the vertical direction of the column 10, allowing for flexible adjustment of the guardrail height and the installation position of the crossbar 20 according to actual needs.

[0024] The crossbar 20 serves as the horizontal support structure of the guardrail, preferably made of steel pipe or aluminum alloy pipe. Its main function is to connect adjacent posts 10 to form a continuous guardrail. The crossbar 20 has a first end and a second end. The first end is pivotally connected to the connecting ring 50 via a first connecting sleeve 30, allowing the first connecting sleeve 30 to rotate and fold relative to the connecting ring 50 to reduce the storage volume. In this embodiment, one end of the first connecting sleeve 30 is configured as a sleeve structure and is fixedly connected to the first end of the crossbar 20, for example, by welding or bolting, to ensure stability. One end of the second connecting sleeve 40 is provided with a fixing hole 41 that matches the second end, and the other end is fixed to the connecting ring 50. The second end is provided with a second quick-release piece 70, and the second end of the crossbar 20 is detachably inserted into the second connecting sleeve 40 via the second quick-release piece 70. In this embodiment, to simplify the structure and manufacturing process, the structure of the second quick-release component 70 is the same as that of the first quick-release component 60, and it is also preferably an elastic self-locking mechanism, with the fixing and unlocking operations being consistent.

[0025] In some embodiments, to further enhance the stability of the guardrail, such as Figure 2 , Figure 3 As shown, the bottom end of the column 10 is provided with a base 80, which is suitable for being fixedly installed on the ground by fasteners. The base 80 can be made of materials such as cast iron or steel plate, and has sufficient weight and strength.

[0026] In this embodiment, as Figure 1 , Figure 2 , Figure 3 As shown, the base 80 has a radially extending skirt 81, on which a through hole 82 is provided. The fastener is a bolt that passes through the through hole 82 to fix the base 80 to the ground, thereby achieving reliable fixation between the base 80 and the ground. Furthermore, to further improve the wind resistance and stability of the guardrail, a space or structure for accommodating counterweights is formed inside or above the base 80. For example, heavy objects such as concrete or gravel can be filled inside the base 80 to increase its weight and improve the overall stability of the guardrail.

[0027] In some embodiments, such as Figure 2 As shown, the first connecting sleeve 30 and the second connecting sleeve 40 are arranged opposite each other in the radial direction of the connecting ring 50, that is, about 180 degrees apart. This helps to balance the force exerted by the crossbar 20 on the connecting ring 50, so that the connecting ring 50 is subjected to more uniform force and the structure is more stable.

[0028] In some embodiments, such as Figure 3As shown, two second connecting sleeves 40 are provided on the connecting ring 50, and the axes of the two second connecting sleeves 40 are perpendicular to each other. In this way, the arrangement of two second connecting sleeves 40 allows the two perpendicular second connecting sleeves 40 to connect to crossbars 20 in different directions, thereby realizing corner fencing with a 90-degree turn or similar angle, effectively enhancing the flexibility and site adaptability of the guardrail.

[0029] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 As shown, the connecting ring 50 has an integrally formed connecting ear 51, on which a shaft hole extending radially along the connecting ring 50 is provided. The first connecting sleeve 30 is provided with a pivot 31, which is rotatably inserted into the shaft hole, so that the first connecting sleeve 30 and the connecting ear 51 are pivotally connected. The crossbar 20 can rotate between an unfolded position perpendicular to the column 10 and a folded position parallel to the column 10 via the first connecting sleeve 30. Using this structural design, the integrally formed connecting ear 51, while ensuring sufficient connection strength, protrudes from the outer wall of the connecting ring 50 to provide a rotational basis for the crossbar 20, allowing the crossbar 20 to freely rotate and fold to a folded position substantially parallel to the column 10, significantly reducing the volume of the folded guardrail.

[0030] The quick-release construction guardrail for civil engineering provided in this embodiment, through the synergistic use of elastic quick-release components and connecting rings, eliminates the need for traditional bolts or welding fixation, enabling rapid manual installation and disassembly without any tools. This significantly shortens construction preparation and dismantling time, improving construction efficiency. Simultaneously, the design of the first and second connecting sleeves allows the crossbars to be rotated and folded to a state essentially parallel to the posts after disassembly, greatly reducing the size of the guardrail after storage, significantly lowering transportation costs and storage space requirements, and facilitating handling and management.
