Description

Technical Field

[0001] This invention belongs to the field of road infrastructure technology, and in particular relates to a construction method for road and bridge safety railings. Background Technology

[0002] Roads and bridges generally consist of several major parts, including roadbed, pavement, bridges, tunnels, and traffic engineering facilities. Guardrails are an indispensable auxiliary tool in road and bridge traffic, effectively preventing oncoming vehicles from cutting in or overtaking each other, and have a positive effect on improving traffic order and enhancing safety.

[0003] The existing guardrails mainly consist of two parts: the railings and the fence posts. The two are fixed together with bolts, which results in low construction efficiency, laborious operation, and inconvenient subsequent maintenance. In addition, the gaps in the guardrails are relatively large, making it difficult to block the headlights of oncoming vehicles, and the light passing through can easily affect the vision of drivers of vehicles in both directions. Summary of the Invention

[0004] The purpose of this invention is to solve the above-mentioned technical problems existing in the prior art and to provide a construction method for road and bridge safety guardrails. The construction is simple, uses fewer bolts, is easy to operate, has low labor intensity, high construction efficiency, and is carried out in an orderly manner, which ensures the assembly quality of the guardrail. Each anti-glare panel forms a reliable and effective light-blocking wall, making it difficult for oncoming vehicle lights to pass through, and has a good light-blocking effect, thus solving the problem of glare from oncoming vehicle lights.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A method for constructing a road and bridge safety railing, characterized by the following steps:

[0007] (a) Clear the road surface and mark the construction area;

[0008] (b) Install the first crossbeam between the two columns to obtain the column assembly;

[0009] (c) Place the column assembly in the construction area and install a buffer cylinder between the two column assemblies;

[0010] (d) The second crossbeam is connected to the connecting seat by fitting the side arm of the connecting seat through the groove at the end of the second crossbeam; then the insert at the bottom of the connecting seat is inserted into the through hole on the first crossbeam, so that the connecting seat is limited on the first crossbeam, and a connecting seat is installed on each first crossbeam.

[0011] (e) Slide the second crossbeam so that the groove at the end of the second crossbeam fits into the side arm of an adjacent connecting seat, thus completing the docking of the second crossbeam with the two adjacent connecting seats.

[0012] (f) Secure the post in place by using nails;

[0013] (g) Pass the threaded post at the bottom of the anti-glare plate through the fixing through hole on the second crossbeam, so that the anti-glare plate is limited on the second crossbeam;

[0014] (h) Determine the deflection angle of the first anti-glare plate, install a fastening nut on the threaded post of the first anti-glare plate, lock the threaded post of the first anti-glare plate with the fastening nut, and restrict the free rotation of the first anti-glare plate.

[0015] (i) Install a limiting rod between two adjacent anti-glare panels.

[0016] Furthermore, step (b) is performed as follows: First, insert the first crossbeam into the slot of the bracket on the side of the column. Then, push the column to bring the two columns closer together until the bracket is against the end of the first crossbeam, completing the limiting installation of the first crossbeam between the two columns, thus obtaining the column assembly. This ensures the contact area between the first crossbeam and the bracket, preventing the first crossbeam from sliding freely, improving the installation reliability of the first crossbeam, and ensuring that the centers of two adjacent first crossbeams are on the same straight line. This facilitates accurate docking of the subsequent second crossbeam with the connecting seat. The construction is simple and efficient, replacing the bolt fixing method, and the operation is quick and labor-saving.

[0017] Furthermore, the side of the column is provided with a mounting block and a mounting bracket. The mounting block is provided with a fixing countersunk hole, and the mounting bracket is provided with a locking slot that is compatible with the first crossbeam.

[0018] Furthermore, the card holder is fixedly connected to the column with screws, ensuring reliable fixation and immediate use. The installation height of the card holder is flexibly adjustable, thereby changing the light-blocking height of the anti-glare plate to suit different actual situations.

[0019] Furthermore, the specific method of step (c) is as follows: the buffer cylinder is fitted with the shaft end through the transverse through hole on the column, and the operation is carried out one by one to limit the buffer cylinder between two adjacent column assemblies, and the positioning is connected. The construction is simple and can be flexibly arranged according to the actual road length, with strong applicability.

[0020] Furthermore, the buffer cylinder includes a central shaft and a cylindrical body. The cylindrical body is rotatably connected to the central shaft. The column has a transverse through hole corresponding to the central shaft, and the central shaft has a positioning part with a cross-sectional diameter larger than that of the transverse through hole. The cylindrical body can be made of polyurethane rubber, which has advantages such as high hardness, good strength, aging resistance, and high elasticity. After being impacted, the cylindrical body can rotate, transferring part of the impact force and reducing the impact effect, making it less prone to damage. The positioning part limits the length of the central shaft that extends into the transverse through hole, ensuring sufficient contact area between the buffer cylinder and the column, and preventing the buffer cylinder from sliding laterally, thus improving the installation stability of the buffer cylinder.

[0021] Furthermore, both ends of the second crossbeam are provided with sleeve grooves, the side of the connecting seat is provided with a side arm corresponding to the sleeve groove, the bottom of the connecting seat is provided with an insert block, the first crossbeam is provided with a through hole corresponding to the insert block; the bottom of the anti-glare plate is provided with a threaded post, and the second crossbeam is provided with a fixing through hole corresponding to the threaded post.

[0022] Furthermore, step (i) is performed as follows: The C-shaped clip at one end of the limiting rod engages with the fixing rod on the left side of the preceding anti-glare panel, and the C-shaped clip at the other end of the limiting rod engages with the fixing rod on the right side of the following anti-glare panel, so that one limiting rod connects two adjacent anti-glare panels simultaneously. Adjacent anti-glare panels are restrained by the limiting rod; the first anti-glare panel is fixed and cannot rotate, while the second anti-glare panel is restrained by the first and third anti-glare panels and cannot rotate freely. This restraint proceeds sequentially from front to back, preventing each anti-glare panel from rotating freely. Adjacent anti-glare panels remain parallel, forming a reliable and effective light-blocking wall, making it difficult for oncoming vehicle lights to pass through. This provides excellent light-blocking effect, is simple to install, highly efficient, and replaces bolt fixing, offering quick and labor-saving operation.

[0023] Furthermore, both sides of the anti-glare panel are equipped with fixing rods, and both ends of the limiting rods are rotatably connected with C-shaped buckles, which correspond to the fixing rods.

[0024] The present invention, by adopting the above-described technical solution, has the following beneficial effects:

[0025] Adjacent anti-glare panels are linked by limiting rods, creating a restraining relationship. The first anti-glare panel is locked and cannot rotate, while the second anti-glare panel is restrained by the first and third anti-glare panels and cannot rotate freely. This restraint proceeds sequentially from front to back, preventing each anti-glare panel from rotating freely. Adjacent anti-glare panels remain parallel, forming a reliable and effective light-blocking wall that makes it difficult for oncoming vehicle lights to pass through. This effectively solves the problem of glare from oncoming headlights. Only the deflection angle of one anti-glare panel needs to be adjusted and fixed; there is no need to adjust the deflection angles of all the other anti-glare panels. The adjustment greatly reduces the difficulty and intensity of construction, making construction simple and efficient. It replaces the bolt fixing method, making operation quick and labor-saving. The combination of multiple anti-glare panels is heavy and presses down on the second crossbeam. The second crossbeam restricts the connecting seat from coming off upward, causing the connecting seat to press down on the first crossbeam, preventing the first crossbeam from coming off upward. The distance between two adjacent anti-glare panels is fixed, thus restricting the free sliding of the second crossbeam. The second crossbeam cannot be freely separated from the connecting seat. The restraint is implemented step by step from top to bottom, ensuring stable installation of each component, reliable assembly, and preventing the whole from falling apart.

[0026] The spacing between two adjacent columns in the X-axis direction is fixed, preventing the buffer cylinder from detaching freely. The spacing between two adjacent columns in the Y-axis direction is fixed, preventing the first crossbeam from detaching freely. The spacing between two adjacent first crossbeams is also fixed, preventing the second crossbeam from detaching freely between the two connecting seats. This step-by-step restraint prevents the whole structure from falling apart, ensuring reliable assembly. Attached Figure Description

Detailed Implementation

[0036] like Figures 1 to 7 As shown, this is a road and bridge safety guardrail used in this invention. The guardrail includes a post 1, a buffer cylinder 2, a first crossbeam 3, a connecting seat 4, a second crossbeam 5, an anti-glare plate 6, and a limiting rod 7. The side of the post 1 is provided with an mounting block 8 and a card seat 9. The mounting block 8 is provided with a fixing countersunk hole 10, and the card seat 9 is provided with a locking slot 11 that is adapted to the first crossbeam 3. The card seat 9 is fixedly connected to the post 1 by screws, which is reliable and can be used immediately after installation. The installation height of the card seat 9 is flexibly adjustable. The anti-glare plate 6 is installed on the first crossbeam 3, thereby changing the light blocking height of the anti-glare plate 6 to suit different actual conditions.

[0037] The buffer cylinder 2 includes a central shaft 12 and a cylinder body 13. The cylinder body 13 is rotatably connected to the central shaft 12. The column 1 has a transverse through hole 14 corresponding to the central shaft 12. The cylinder body 13 can be made of polyurethane rubber, which has advantages such as high hardness, good strength, aging resistance, and high elasticity, avoiding hard collisions and ensuring high safety. After being impacted, the cylinder body 13 can rotate to transfer part of the impact force, reducing the impact effect and making it less prone to damage. The central shaft 12 has a positioning part 15, the cross-sectional diameter of which is larger than the cross-sectional diameter of the transverse through hole 14. The positioning part 15 limits the length of the central shaft 12 that passes through the transverse through hole 14, ensuring sufficient contact area between the buffer cylinder 2 and the column 1, and preventing the buffer cylinder 2 from sliding laterally, thus improving the installation stability of the buffer cylinder 2.

[0038] Both ends of the second crossbeam 5 are provided with sleeve grooves 16, the side of the connecting seat 4 is provided with side arms 17 corresponding to the sleeve grooves 16, the bottom of the connecting seat 4 is provided with insert blocks 18, the first crossbeam 3 is provided with through holes 19 corresponding to the insert blocks 18; the bottom of the anti-glare plate 6 is provided with threaded posts 20, the second crossbeam 5 is provided with fixing through holes 21 corresponding to the threaded posts 20; both sides of the anti-glare plate 6 are provided with fixing rods 22, and both ends of the limiting rod 7 are rotatably connected with C-type buckles 23, which correspond to the fixing rods 22.

[0039] A method for constructing safety railings for roads and bridges includes the following steps:

[0040] (a) Clear the road surface and mark the construction area;

[0041] (b) Install the first crossbeam 3 between the two columns 1. Specifically, first insert the first crossbeam 3 into the slot 11 of the side bracket 9 of the column 1, then push the column 1 to bring the two columns 1 closer together until the bracket 9 is attached to the end of the first crossbeam 3, thus completing the limiting installation of the first crossbeam 3 between the two columns 1 and obtaining the column assembly.

[0042] This ensures the contact area between the first crossbeam 3 and the card seat 9, making it less prone to free sliding and improving the installation reliability of the first crossbeam 3. It also ensures that the centers of two adjacent first crossbeams 3 are on the same straight line, which facilitates the accurate docking of the subsequent second crossbeam 5 and the connecting seat 4. The construction is simple and efficient, replacing the bolt fixing method, and the operation is quick and labor-saving.

[0043] (c) The column assembly is placed in the construction area, and the buffer cylinder 2 is installed between the two column assemblies. The specific method is as follows: the end of the central axis 12 is fitted through the transverse through hole 14 on the column 1, and the operation is carried out one by one to limit the buffer cylinder 2 between the two adjacent column assemblies, and the positioning is connected. The construction is simple and can be flexibly arranged according to the actual road length, and it has strong applicability.

[0044] (d) The second crossbeam 5 is connected to the connecting seat 4 by the sleeve groove 16 at the end of the second crossbeam 5 and the side arm 17 of the connecting seat 4; then the insert block 18 at the bottom of the connecting seat 4 is inserted into the through hole 19 on the first crossbeam 3, so that the connecting seat 4 is limited on the first crossbeam 3, and a connecting seat 4 is installed on each first crossbeam 3.

[0045] (e) The length of the second crossbeam 5 is less than the distance between the two first crossbeams 3. The second crossbeam 5 is slid so that the groove 16 at the end of the second crossbeam 5 fits onto the side arm 17 of an adjacent connecting seat 4, thus completing the docking of the second crossbeam 5 with the two adjacent connecting seats 4. During disassembly, the combination of one connecting seat 4 and one second crossbeam 5 can be disassembled separately without having to disassemble the entire combination of the connecting seat 4 and the second crossbeam 5, which reduces the operational intensity and facilitates local maintenance and replacement.

[0046] (f) Drive anchor bolts into the fixed countersunk hole 10 to fix the column 1 in place. The distance between two adjacent columns 1 in the X-axis direction is fixed, and the buffer cylinder 2 cannot be detached freely. The distance between two adjacent columns 1 in the Y-axis direction is fixed, and the first crossbeam 3 cannot be detached freely. The distance between two adjacent first crossbeams 3 is also fixed, and the second crossbeam 5 cannot be detached freely between the two connecting seats 4. The system is restrained step by step, and the whole structure will not fall apart, ensuring reliable assembly.

[0047] (g) Pass the threaded post 20 at the bottom of the anti-glare plate 6 through the fixing through hole 21 on the second crossbeam 5, so that the anti-glare plate 6 is limited on the second crossbeam 5. The installation is simple, and it can be used immediately after installation. It is flexible and convenient.

[0048] (h) Determine the deflection angle of the first anti-glare plate 6, install a fastening nut on the threaded post 20 of the first anti-glare plate 6, so that the fastening nut is attached to the bottom surface of the second crossbeam 5, and lock the threaded post 20 of the first anti-glare plate 6 by fastening the nut, thus restricting the free rotation of the first anti-glare plate 6.

[0049] (i) Install a limiting rod 7 between two adjacent anti-glare panels 6. Specifically, the C-shaped buckle 23 at one end of the limiting rod 7 is used to lock the fixing rod 22 on the left side of the previous anti-glare panel 6, and the C-shaped buckle 23 at the other end of the limiting rod 7 is used to lock the fixing rod 22 on the right side of the next anti-glare panel 6, so that one limiting rod 7 connects two adjacent anti-glare panels 6 at the same time.

[0050] Adjacent anti-glare panels 6 are restrained by limiting rods 7. The first anti-glare panel 6 is locked and cannot rotate, while the second anti-glare panel 6 is restrained by the first and third anti-glare panels 6 and cannot rotate freely. This restraint proceeds from front to back, preventing each anti-glare panel 6 from rotating freely. Adjacent anti-glare panels 6 remain parallel, forming a reliable and effective light-blocking wall. The headlights of oncoming vehicles are difficult to penetrate, providing excellent light blocking and solving the problem of glare from oncoming headlights. Only the deflection angle of one anti-glare panel 6 needs to be adjusted and fixed; there is no need to adjust the deflection angle of each anti-glare panel 6. The adjustment greatly reduces the difficulty and intensity of construction, making construction simple and efficient. It replaces the bolt fixing method, making operation quick and labor-saving. The combination of multiple anti-glare plates 6 is heavy and presses down on the second crossbeam 5. The second crossbeam 5 restricts the connecting seat 4 from coming off upward, so that the connecting seat 4 presses down on the first crossbeam 3, preventing the first crossbeam 3 from coming off upward. The distance between two adjacent anti-glare plates 6 is fixed, which in turn restricts the free sliding of the second crossbeam 5. The second crossbeam 5 cannot be freely separated from the connecting seat 4. The restraint is carried out step by step from top to bottom, and the installation of each component is stable and the assembly is reliable. The whole is not easy to fall apart.

[0051] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
