Description

Technical Field

[0001] This utility model relates to the field of road widening technology, and in particular to a road reconstruction, widening and reinforcement structure. Background Technology

[0002] As cities develop, the number of vehicles increases. To allow vehicles to pass through certain sections of road more quickly, existing roads are widened. During road widening, wooden planks are used for reinforcement to prevent the edges from collapsing. However, when using wooden planks, only the edges can be reinforced; the upper surface of the edges cannot be pressed down, as this can easily cause the upper edge to bulge, and the planks cannot be easily connected to each other.

[0003] Publication No. CN220888189U discloses a road widening and reinforcement structure, including a pressure plate, side baffles, and positioning rods. The side baffles are movably embedded inside the pressure plate near its rear. The positioning rods are embedded in the center of the rear surface of the pressure plate. Fixing plates are movably embedded in the rear surface of the side baffles near their sides. This road widening and reinforcement structure utilizes fasteners and fixing plates to fix the side baffles at the edge of the widened road, thus reinforcing the edge. The rear end of the positioning rod is pulled out from the positioning hole of the side baffle, and then the pressure plate is moved. Once the height of the pressure plate is adjusted, the force pulling the positioning rod is released. The positioning rod then inserts into another positioning hole under the pushing action of a spring, thus positioning the pressure plate and preventing bulging at the upper edge of the road. Multiple pressure plates can be easily connected together with the cooperation of locking blocks and locking sleeves.

[0004] Traditional road widening structures use rigid connections, and the impact force of vehicles passing by is directly transmitted to the curb, causing the concrete at the connection point to crack and the bolts to loosen. Existing support structures need to be customized in height or have concrete bases poured, which has a long construction period and cannot be adjusted. How can we achieve rapid installation and adaptability to the ground? Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this utility model provides a road reconstruction, widening and reinforcement structure. The traditional road widening structure uses rigid connections, and the impact force of vehicles passing through is directly transmitted to the curb, causing the concrete at the connection to crack and the bolts to loosen. Existing support structures require customized height or the pouring of concrete bases, which has a long construction period and cannot be adjusted. The question is how to achieve rapid installation and adaptability to the ground.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a road reconstruction, widening and reinforcement structure, including a curb connecting plate, a plurality of transverse positioning bolts are arranged on the curb connecting plate, a widening plate is rotatably installed on the top of the curb connecting plate, a plurality of buffer members are arranged between the widening plate and the curb connecting plate, and a plurality of support and reinforcement mechanisms are arranged at the bottom of the widening plate.

[0007] Preferably, the buffer component includes a semi-circular metal component and two diagonal braces. The two diagonal braces are fixedly installed at both ends of the semi-circular metal component and are respectively fixedly installed with the widening plate and the curb connecting plate. The semi-circular metal component has an arc-shaped buffer support force.

[0008] Preferably, the top of the curb connecting plate is provided with a notch, the side of the widening plate is fixedly installed with a protrusion, and both sides of the protrusion are fixedly installed with a shaft pin. The inner walls of both sides of the notch are provided with shaft pin positioning grooves, and the two shaft pins are rotatably engaged with the two shaft pin positioning grooves.

[0009] Preferably, the support and reinforcement mechanism includes three support rods, all of which are fixedly installed at the bottom of the widening plate. The bottom of the three support rods is fixedly installed on the same support plate. The support plate has a screw hole, and a screw rod is threaded into the screw hole. A screw head is fixedly installed on the top of the screw rod.

[0010] Preferably, a locking nut is threaded onto the outer side of the screw, and the locking nut is located above the support plate.

[0011] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0012] 1. Dynamic buffering and vibration reduction effect: The buffer component, composed of a semi-circular metal arc structure and diagonal bracing, provides elastic deformation space when a vehicle is subjected to impact, absorbing vibration energy and reducing the impact force transmitted to the curb. This reduces stress concentration at the curb connection, extends structural life, and improves ride comfort.

[0013] 2. Settlement Adaptability: The widening plate, through the rotational engagement of the pivot pin and notch groove, allows for slight relative rotation between the widening plate and the curb connecting plate, accommodating uneven settlement between the old and new roadbeds. This avoids rigid structure fracture caused by differential settlement and reduces maintenance requirements.

[0014] 3. Adjustable support height: The support and reinforcement mechanism allows for height adjustment of the support plate through the threaded engagement of the screw and locking nut, adapting to different ground flatness or roadbed thicknesses. No customized base is required, enhancing construction flexibility.

[0015] 4. Automatic reset and anti-deformation effect: The semi-circular metal part of the buffer component generates a "reset support elastic force" after the load is removed, pushing the widened plate back to its original position and preventing permanent bending deformation. It can withstand repeated crushing by heavy vehicles and maintain the geometric stability of the widened structure.

[0016] 5. Modular and rapid installation: The lateral positioning bolts, shaft pin rotation mechanism, and support mechanism all use prefabricated components, requiring only bolt fixing, insertion, and thread locking on site, reducing welding procedures. This lowers the technical threshold for construction, improves installation efficiency, and supports standardized mass production.

[0017] This device achieves a multi-level synergistic reinforcement effect: vertical support (the support mechanism bears the vertical load), diagonal reinforcement (the buffer provides lateral support force), and lateral fixing (the lateral bolts anchor the curb), forming a three-dimensional force network that distributes the load to the curb and foundation, reducing the risk of local failure.
