Description

Technical Field

[0001] This application relates to the field of bridge construction technology, and in particular to a bridge crash barrier and its lamp holder installation structure. Background Technology

[0002] Bridge crash barriers, as an auxiliary structure of bridges, are an important safety protection structure. Current technologies typically employ cast-in-place construction for bridge crash barriers, where the crash barrier is poured on-site after the main bridge structure is completed. Light fixtures are then installed on the crash barrier to mount the bridge streetlights.

[0003] Regarding the aforementioned technologies, the inventors believe that pouring concrete for the bridge crash barrier and installing light fixtures after the main bridge construction is completed would take too long. Utility Model Content

[0004] The purpose of this application is to provide a bridge crash barrier and its lamp holder installation structure to improve the problem of the long construction period required for pouring bridge crash barriers and installing lamp holders after the main bridge construction is completed.

[0005] This application provides a bridge crash barrier and its lamp holder mounting structure, which adopts the following technical solution:

[0006] A bridge crash barrier and its lamp holder installation structure include a bridge body. Grooves are provided on both sides of the bridge body along the length of the bridge body. A plurality of crash barrier components are provided in the grooves of the bridge body. The crash barrier components are connected to the bottom surface of the grooves and are connected along the groove direction of the bridge body to form a crash barrier.

[0007] By adopting the above technical solution, a groove is set along the length of one side of the bridge body, and a crash barrier component is set in the groove. The groove is used to make the crash barrier component set in a straight line along the side of the bridge body, preventing the crash barrier component from shifting during installation. The crash barrier is composed of crash barrier components, which shortens the construction period compared to the cast-in-place crash barrier, prevents the crash barrier from shifting, and makes the construction of the bridge crash barrier more convenient and faster.

[0008] Optionally, a protrusion is provided in the groove of the bridge body along the length direction, a sinkhole is provided at the bottom of the crash barrier assembly, the inner sidewall of the sinkhole is in contact with the protrusion, a fixing hole one is provided on the protrusion, a fixing hole two communicating with the sinkhole is provided on the side of the crash barrier assembly, the fixing hole two corresponds to the fixing hole one, and a fixing member one is inserted into the fixing hole two and the fixing hole one.

[0009] By adopting the above technical solution, a protrusion is provided in the groove of the bridge body. The protrusion is fitted with the groove at the bottom of the crash barrier assembly to further restrict the crash barrier assembly. A fixing member is passed through fixing hole one on the protrusion and fixing hole two on the crash barrier assembly to connect and fix the crash barrier assembly to the protrusion, so as to prevent the crash barrier assembly from detaching from the bridge body after being impacted, causing the crash barrier to be missing and damaging the bridge body.

[0010] Optionally, the crash barrier assembly is provided with a guide block, and the guide block is provided with a guide groove on the side near the bridge body that is smoothly connected to the side of the crash barrier assembly.

[0011] By adopting the above technical solution, guide blocks are installed on the crash barrier assembly. The guide grooves on the guide blocks are smoothly connected to the side wall of the crash barrier assembly. When a car hits the crash barrier and comes into contact with the guide block, the guide block provides some resistance to the car. At this time, the guide block plays a role in changing the direction of the car's movement, reducing the risk of the car flying over the crash barrier or even falling off the bridge and causing danger.

[0012] Optionally, one end of the crash barrier assembly is provided with a limiting block, and the other end of the crash barrier assembly is provided with a limiting groove, wherein the limiting block of the crash barrier assembly fits into the limiting groove of another adjacent crash barrier assembly.

[0013] By adopting the above technical solution, a limiting block is set at one end of the crash barrier component and a limiting groove is set at the other end of the crash barrier component. The crash barrier component fits into the limiting groove of the adjacent crash barrier component through the limiting block, connecting the crash barrier components into a crash barrier, making the connection between the crash barrier components tighter and preventing the crash barrier components from separating from each other.

[0014] Optionally, a limiting hole one is provided on the limiting block of the anti-collision wall assembly, and a limiting hole two is provided on the limiting groove of the adjacent anti-collision wall assembly at the position corresponding to the limiting hole, and limiting members are inserted into the limiting hole one and the limiting hole two.

[0015] By adopting the above technical solution, the two anti-collision wall components are fixed by the limiting member passing through the limiting hole one and the limiting hole two, and the connection between the two adjacent anti-collision wall components is tighter, preventing the adjacent anti-collision wall components from being misaligned after being hit by a collision, thus preventing the anti-collision wall from breaking apart.

[0016] Optionally, a support plate one is provided on the side of the bridge body near the side wall of the crash barrier assembly. The support plate one has a connecting hole and a connecting rod is provided in the connecting hole. A support plate two is provided at the end of the connecting rod near the crash barrier assembly. The support plate two abuts against the side wall of the crash barrier assembly. A buffer component one is provided between the support plate one and the support plate two. A support rod is provided between the support plate one and the bridge body.

[0017] By adopting the above technical solution, a support plate 1 is set on the main body of the bridge, a connecting rod and a buffer component 1 are set on the support plate 1, and a support plate 2 is set on the connecting rod, so that the support plate 2 abuts against the anti-collision wall assembly. After the anti-collision wall assembly is impacted, the buffer component 1 between the support plate 2 and the support plate 1 retracts to buffer the anti-collision wall assembly and prevent the anti-collision wall assembly from detaching from the protrusion and causing damage to the main body of the bridge.

[0018] Optionally, the end face of the limiting groove of the anti-collision wall assembly is provided with a buffer member two, and the buffer member two abuts against the end face of the adjacent anti-collision wall assembly provided with a limiting block.

[0019] By adopting the above technical solution, a buffer component is set in the first degree of the limit groove of the anti-collision wall component to buffer the adjacent anti-collision wall components and prevent the two adjacent anti-collision wall components from colliding with each other and causing damage to the anti-collision wall components.

[0020] Optionally, a separator is provided between the bottom of the crash barrier assembly and the groove of the bridge body.

[0021] By adopting the above technical solution, the crash barrier assembly and the groove are isolated by the isolation component to prevent moisture from entering the sink of the crash barrier assembly and causing corrosion to the connection between the crash barrier assembly and the protrusion.

[0022] Optionally, the two ends of the anti-collision wall assembly are provided with mounting grooves on the limiting block and the limiting groove. A bridge lamp holder is provided in the mounting groove. A slot is provided on the side wall of the mounting groove. A fixing plate corresponding to the slot is provided on the side wall of the bridge lamp holder. A fixing hole three is provided on the fixing plate. A fixing hole four communicating with the fixing hole three is provided on the inner side wall of the slot. A fixing member two is inserted into the fixing hole three and the fixing hole four.

[0023] By adopting the above technical solution, mounting grooves are set at both ends of the crash barrier components, so that during installation, adjacent crash barrier components can fix the bridge light holders through the mounting grooves. The bridge light holders are prevented from detaching from the mounting grooves by the slots and the mounting plates on the bridge light holders.

[0024] Optionally, a fixing groove is provided on the bridge lamp holder, and the street lamp body is inserted into the fixing groove. An adsorption component is provided at the bottom of the second mounting groove, and the adsorption component adsorbs the street lamp body.

[0025] By adopting the above technical solution, an adsorption component is set at the bottom of the fixing groove of the bridge lamp holder to adsorb and fix the street lamp body, making it difficult for the street lamp body to detach from the bridge lamp holder.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. A groove is provided on one side of the bridge main body, and a protrusion is set in the groove. The crash barrier assembly is installed on the protrusion in the groove. The groove and the protrusion are used to make the crash barrier assembly straight along the side of the bridge main body, so as to prevent the crash barrier assembly from shifting during installation. The crash barrier assembly is composed of crash barrier components, which shortens the construction period compared with the cast-in-place crash barrier, and makes the construction of the bridge crash barrier more convenient and faster.

[0028] 2. Install guide blocks on the crash barrier assembly. The guide grooves on the guide blocks are smoothly connected to the side wall of the crash barrier assembly. When a car crashes into the crash barrier out of control, the guide blocks will generate a certain amount of resistance to the car when the car comes into contact with the guide blocks. The guide blocks play a role in changing the direction of the car's movement and prevent the car from flying over the crash barrier or even falling off the bridge, causing danger.

[0029] 3. Install support plate one on the side of the bridge main body closest to the crash barrier. Set a connecting rod and buffer component one on support plate one. Set support plate two on the connecting rod so that support plate two abuts against the crash barrier assembly. After the crash barrier assembly is impacted, buffer component one between support plate two and support plate one will retract to buffer the crash barrier assembly and prevent the crash barrier assembly from detaching from the protrusion and causing damage to the bridge main body.
