Abstract
Description
Technical Field
[0001] This utility model relates to the field of ECC bridges, and more specifically, to an ECC bridge anti-collision guardrail. Background Technology
[0002] Traditional concrete, due to its high brittleness, is prone to cracking under the combined effects of mechanical loads and environmental factors during long-term service, leading to structural damage. Therefore, concrete structures often face durability challenges such as cracking and spalling under the coupled effects of loads and complex environments. In contrast, engineering cementitious composites (ECCs) possess excellent tensile toughness and multi-crack characteristics, maintaining good load-bearing capacity and functional integrity even when cracking occurs, significantly improving structural durability and service safety.
[0003] A search revealed that Chinese patent CN219218668U discloses "A Quick-Replaceable Bridge Crash Barrier," relating to the field of bridge protection structure technology. The barrier includes columns and a prefabricated energy-absorbing shell. The bottom end of the column is fixedly connected to the top end of the bridge deck beam. The prefabricated energy-absorbing shell is detachably fixedly connected to the side end face of the column. The prefabricated energy-absorbing shell is made of ECC, UHPC, or other high-performance cement-based materials. The column has an L-shaped structure or an inverted T-shaped structure. The horizontal section of the L-shaped or inverted T-shaped structure forms the bottom of the column. When the column is L-shaped, only one side of the column with the horizontal section is connected to a prefabricated energy-absorbing shell, and the column and the prefabricated energy-absorbing shell form a side guardrail. When the column is inverted T-shaped, both sides of the column are connected to prefabricated energy-absorbing shells, and the column and the prefabricated energy-absorbing shell form a central guardrail. This new type of structure not only provides impact protection but also features quick replacement, light weight, structural stability, and strong energy dissipation capacity. However, it still has the following drawbacks:
[0004] (1) Currently, the ECC bridge crash barriers on the market have low overall energy absorption capacity when in use, which makes it difficult to increase energy absorption capacity, thereby reducing overall usability and making it difficult to use efficiently.
[0005] (2) Currently, the ECC bridge crash barriers on the market have low overall support when in use, which reduces the overall protection capability. They are prone to breakage in the event of a violent collision, causing vehicles to run out and reducing safety.
[0006] Therefore, we have made improvements to this and proposed an ECC bridge crash barrier. Utility Model Content
[0007] The purpose of this invention is to address the problem that the overall energy absorption capacity is currently low, making it difficult to increase energy absorption capacity and thus reducing overall usability.
[0008] To achieve the above-mentioned objectives, this utility model provides the following technical solution:
[0009] An ECC bridge crash barrier is proposed to improve the above-mentioned problems.
[0010] The present invention specifically includes a frame, an energy-absorbing mounting assembly disposed inside the frame, and a support and fixing assembly disposed on the surface of the frame.
[0011] The energy-absorbing installation assembly includes a vertical barrel disposed inside the frame. The vertical barrel has an inner cavity, and a water storage tank is detachably connected inside the inner cavity. A fixed column is fixedly connected inside the vertical barrel, and the vertical barrel absorbs energy through collision.
[0012] The support and fixing assembly includes a support rod detachably connected to one side of the frame surface. One end of the support rod is fixedly connected to a mounting block. The mounting block has a mounting hole on its surface, and a mounting column is connected inside the mounting hole. The support rod provides impact support for the frame.
[0013] As a preferred technical solution of this utility model, the energy-absorbing installation component further includes a connecting seat fixedly connected to both ends of the fixed column, and the surface of the connecting seat is provided with a connecting hole.
[0014] As a preferred technical solution of this utility model, the connecting seat is attached to the inner surface of the frame, and a bolt is fitted inside the connecting hole.
[0015] As a preferred technical solution of this utility model, one end of the bolt is connected to the inside of the frame, and there are multiple vertical barrels arranged in an array.
[0016] As a preferred technical solution of this utility model, the support and fixing component further includes an inner groove formed inside the support rod, and a steel plate is connected inside the inner groove.
[0017] As a preferred technical solution of this utility model, there are multiple support rods, and a mounting column is connected to the other end of the surface of each support rod.
[0018] As a preferred technical solution of this utility model, a crossbar is connected to the other end surface of the support rod, and a mounting column is connected to the inside of the crossbar.
[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0020] In the solution of this utility model:
[0021] 1. The overall support structure is formed by a frame, which is hollow inside. Connecting seats are installed at both ends of the frame, fitting snugly against the inner surface of the frame. Each connecting seat has connecting holes for bolt connection, which then secures the frame to the frame, facilitating installation and disassembly. Fixed columns are fixedly connected between the connecting seats, and vertical barrels are installed on the surface of these columns. Water storage tanks are installed within the internal cavities of these vertical barrels, absorbing water during collisions and increasing overall collision resistance. Therefore, the ECC bridge crash barrier exhibits high energy absorption capacity, enhancing its overall usability and enabling efficient use.
[0022] 2. During installation, mounting blocks are attached to one side of the frame surface. These blocks connect to mounting posts through mounting holes on their surfaces, securing them to the frame surface. This allows for the installation of support rods fixed to one end of the mounting blocks. The other end of the support rod is also installed to a crossbar via mounting posts. The crossbar is fixed to the ground, supporting the support rod. The support rod is angled for easy load-bearing. Steel plates are installed on the support rod through internal grooves, increasing overall support and strength. Consequently, the ECC bridge crash barrier has a lower overall support level, improving overall protection and reducing the likelihood of breakage and vehicle scrambling during severe collisions, thus enhancing safety.

[0034] like Figure 1-5As shown, this embodiment proposes an ECC bridge crash barrier, including a frame 1, an energy-absorbing mounting assembly disposed inside the frame 1, and a support and fixing assembly disposed on the surface of the frame 1. The energy-absorbing mounting assembly includes a vertical barrel 204 disposed inside the frame 1, with an inner cavity 205 inside the vertical barrel 204. A water storage tank 206 is detachably connected inside the inner cavity 205. A fixing post 207 is fixedly connected inside the vertical barrel 204. The vertical barrel 204 absorbs energy upon impact. The water storage tank 206 is installed in the vertical barrel 204 through the inner cavity 205, and the water storage tank 206 stores water. In the event of a collision, it absorbs energy, increasing the overall collision resistance. The support and fixing assembly includes a detachable... The support rod 301 connected to one side of the surface of the frame 1 is removed. One end of the support rod 301 is fixedly connected to the mounting block 302. The surface of the mounting block 302 has a mounting hole 303. The mounting post 304 is connected inside the mounting hole 303. The support rod 301 provides impact support for the frame 1. The mounting blocks 302 are attached to one side of the surface of the frame 1. The mounting blocks 302 are connected to the mounting posts 304 through the mounting holes 303 on their surfaces. The mounting posts 304 fix the mounting blocks 302 to the surface of the frame 1, thereby installing the support rod 301 fixedly connected to one end of the mounting block 302. The other end of the support rod 301 is also installed to the crossbar 305 through the mounting posts 304.
[0035] like Figure 2 As shown, the energy-absorbing installation assembly also includes a connecting seat 201 fixedly connected to both ends of the fixed column 207. The surface of the connecting seat 201 is provided with a connecting hole 202. The connecting seat 201 increases the connection points of the whole, making it easier to install and fix. The connecting hole 202 facilitates installation.
[0036] like Figure 2 As shown, the connecting seat 201 is attached to the inner surface of the frame 1, and the connecting hole 202 is fitted with a bolt 203. The bolt 203 is connected to the connecting hole 202 to facilitate the fixing of the frame 1 and increase the disassembly and connection.
[0037] like Figure 1 and Figure 2 As shown, one end of the bolt 203 is connected to the inside of the frame 1. There are multiple vertical barrels 204 arranged in an array. The multiple vertical barrels 204 increase safety and facilitate energy absorption in the event of a collision.
[0038] like Figure 5 As shown, the support and fixing assembly also includes an inner groove 306 opened inside the support rod 301. A steel plate 307 is connected inside the inner groove 306. The inner groove 306 opened inside the support rod 301 increases the mounting point, and the steel plate 307 is connected in it to increase the support during impact and reduce the possibility of breakage.
[0039] like Figure 3 As shown, there are multiple support rods 301. The other end of the surface of the support rod 301 is connected to a mounting post 304. The support rod 301 is installed and connected through the mounting post 304, making it easy to disassemble and use.
[0040] like Figure 3 As shown, a crossbar 305 is connected to the other end of the support rod 301. A mounting post 304 is connected inside the crossbar 305. The crossbar 305 is connected to the ground to increase the overall connection stability.
[0041] Specifically, in use, the frame 1 forms an integral support structure. The interior of the frame 1 is hollow, and connecting seats 201 are installed at both ends inside the frame 1. The connecting seats 201 are attached to the inner surface of the frame 1, and each connecting seat 201 has connecting holes 202. Bolts 203 are used to connect the connecting seats 201 and then fix them to the frame 1, facilitating installation and disassembly. Fixing posts 207 are fixedly connected between the connecting seats 201. Vertical barrels 204 are installed on the surface of the fixing posts 207. Water storage tanks 206 are installed in the vertical barrels 204 through an inner cavity 205. Water is stored in the water storage tanks 206, which absorb energy in the event of a collision, increasing the overall collision resistance. Therefore, the ECC bridge crash barrier has high overall energy absorption capacity, which is easy to increase, thereby improving the overall usability and facilitating efficient use. Mounting blocks 302 are attached to one side of the frame 1. The mounting blocks 302 are connected to the mounting posts 304 through mounting holes 303 on the surface. The mounting posts 304 fix the mounting blocks 302 to the surface of the frame 1, thereby installing the support rod 301 fixedly connected to one end of the mounting blocks 302. The other end of the support rod 301 is also installed to the crossbar 305 through the mounting posts 304. The crossbar 305 is fixed to the ground and supports the support rod 301. The support rod 301 is inclined to facilitate stress support. The support rod 301 is installed with steel plates 307 through the inner grooves 306. The steel plates 307 increase the overall support, making it easier to support and increasing strength. As a result, when the ECC bridge crash barrier is in use, the overall support is relatively low, thereby improving the overall protection capability. In the event of a severe collision, it is not easy to break and cause the vehicle to run out, thus improving safety.
[0042] All technical features in this embodiment can be freely combined according to actual needs.
[0043] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
