Description

Technical Field

[0001] This utility model relates to the technical field of traffic safety protection facilities, specifically a spliced ​​temporary highway crash barrier. Background Technology

[0002] Temporary crash barriers are crucial for ensuring traffic safety during highway construction, temporary detours, and accident handling. Traditional temporary barriers often use rigid steel structures or simple water-filled barriers, which suffer from poor energy absorption, complex installation, and low reusability. For example, while steel barriers have a certain strength, they can easily cause vehicles to bounce upon impact and are difficult to disassemble quickly; while plastic water-filled barriers or sandbag barriers have limited cushioning capacity and are unable to withstand high-speed impacts. In addition, existing temporary barriers lack sufficient warning function, especially at night or in inclement weather, which can easily lead to secondary accidents. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides the following technical solution: a modular temporary crash barrier for highways, comprising H-shaped steel posts, energy-absorbing modules, and connecting components.

[0004] The bottom of the H-shaped steel column is equipped with a fixing structure;

[0005] The energy-absorbing module consists of a double-layer corrugated aluminum plate and an embedded honeycomb aluminum core.

[0006] The connection assembly includes pins and buckles on both sides of the energy absorption module and rubber buffer pads at the module connection.

[0007] Preferably, the bottom of the H-shaped steel column is provided with shear bolts.

[0008] Preferably, the width of the energy-absorbing module is 1 to 2 meters, and the modules are connected by metal hooks.

[0009] Preferably, the surface of the energy-absorbing module is provided with reflective strips and solar-powered LED warning lights.

[0010] Preferably, the energy-absorbing module has a detachable counterweight groove at its bottom.

[0011] Preferably, the pin buckle is provided with a slot, and the H-shaped steel column is provided with a self-expanding pin.

[0012] Preferably, the honeycomb aluminum core is made of aluminum foam.

[0013] Preferably, the H-shaped steel column is fixed by pre-embedded sleeves or expansion bolts.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The modular energy-absorbing modules, combined with pin buckles and rubber buffer pads, achieve the dual advantages of rapid assembly and high-efficiency energy absorption. The shear bolts and pre-embedded sleeves at the base of the H-shaped steel columns enhance overall stability and facilitate emergency disassembly. Reflective strips and solar-powered LED warning lights improve nighttime visibility, while the detachable counterweight slot adapts to different working conditions. This structure combines lightweight design, high energy absorption efficiency, and ease of construction, improving the protective performance and adaptability of temporary guardrails.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-4 As shown, the modular temporary highway crash barrier of this embodiment includes H-shaped steel posts 1, energy-absorbing modules 2, and connecting components.

[0024] The bottom of the H-beam steel column 1 is equipped with a fixing structure;

[0025] The energy absorption module 2 consists of a double-layer corrugated aluminum plate 21 and an embedded honeycomb aluminum core 22;

[0026] The connecting components include pins and clips 23 located on both sides of the energy-absorbing module 2 and rubber buffer pads 3 located at the module connection.

[0027] The bottom of the H-beam steel column 1 is equipped with shear bolts 4, which can be controlled to break during violent collisions, ensuring stability during normal use and absorbing energy through collapse when subjected to impact.

[0028] The width of the energy-absorbing module 2 is 1 to 2 meters. The modules are connected by metal hooks 24. The standardized size facilitates mass production and rapid transportation.

[0029] The surface of the energy-absorbing module 2 is equipped with reflective strips 25 and solar-powered LED warning lights 26 to improve visibility at night and in adverse weather conditions.

[0030] The bottom of the energy absorption module 2 is equipped with a detachable counterweight groove 27, which allows the counterweight to be adjusted according to the on-site wind force and foundation conditions.

[0031] The pin buckle 23 is equipped with a slot 231, and the H-shaped steel column 1 is equipped with a self-expanding pin 232. The plug-in installation enables rapid assembly.

[0032] The honeycomb aluminum core 22 is made of foamed aluminum, which has better plastic deformation ability compared to ordinary honeycomb aluminum.

[0033] The H-beam steel column 1 is fixed by pre-embedded sleeves or expansion bolts, which can adapt to different foundation conditions (concrete / asphalt / soil).

[0034] The working principle of this utility model is as follows:

[0035] The H-beam steel column 1 is fixed to the ground by pre-embedded sleeves or expansion bolts. The shear bolt 4 at the bottom breaks upon severe impact, thus buffering the impact force and protecting the foundation structure. The energy-absorbing module 2 is quickly installed on the H-beam steel column 1 via a pin clip 23 (in conjunction with a self-expanding pin 232). The modules are connected by metal hooks 24. The rubber buffer pad 3 absorbs part of the kinetic energy during the collision. When a vehicle collides, the double-layer corrugated aluminum plate 21 and the honeycomb aluminum core 22 made of foam aluminum efficiently dissipate the impact energy through plastic deformation, reducing the risk of rebound. The detachable counterweight groove 27 enhances stability, and the reflective strip 25 and solar LED warning light 26 improve nighttime visibility. This structure combines efficient protection with convenient assembly and disassembly through modular energy absorption, buffer connection, and collapsible design.
