Description

Technical Field

[0001] The utility model relates to the technical field of steel guardrail structures, in particular to an SB-level movable steel guardrail structure used for road construction. Background Art

[0002] Steel guardrails are a crucial component of road safety infrastructure, often used to separate opposing lanes, protect roadside edges, and provide temporary safety barriers in construction areas. Their structural design requires sufficient strength and stability to withstand the impact of a vehicle collision and ensure the safety of both vehicles and passengers.

[0003] SB-grade guardrails represent a specific grade of corrugated guardrails. These guardrails utilize a three-wave guardrail panel but feature square tube posts, resulting in increased overall strength and the ability to withstand vehicle impacts. SB-grade guardrails are primarily installed on straight and curved sections of highways, particularly in areas with high speeds and heavy traffic, to reduce the severity of accidents and provide greater safety for drivers and passengers.

[0004] Common SB-grade steel guardrail structures generally use guardrail panels to absorb and disperse collision energy. The guardrail panels are fixed by columns and are usually installed in the ground to provide vertical support. Anti-blocking components are installed between the guardrail panels and columns to improve the stability and anti-collision ability of the guardrail.

[0005] However, due to the complex structure of the steel guardrail structure, it takes a long time to install the steel guardrail structure. At the same time, due to the heavy weight of the steel guardrail structure, it is difficult to move the steel guardrail structure. After long-term use, the base of the steel guardrail structure will also be subjected to long-term extrusion, which makes the base easy to deform, reducing the overall firmness of the steel guardrail structure.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field without creative work in the embodiments of the present invention are within the scope of protection of the present invention.

[0031] This utility model provides a technical solution, an SB-level movable steel guardrail structure for road construction, please refer to Figure 1 , comprising a base 1, the upper surface of which is provided with double crossbeams 2;

[0032] The crossbeam sleeve 3 is provided on both sides of the double crossbeam 2. The upper surfaces of the double crossbeam 2 are both screwed with first bolts 4. The first bolts 4 are common carriage bolts on the market.

[0033] The first internal horizontal support baffle 5 is arranged in the inner cavity of the base 1. The base 1 is a trapezoidal design. The lower part of the inner cavity of the base 1 is installed with a second internal horizontal support baffle 6. Figure 4 , the surface of the second internal cross brace baffle 6 is screwed with special anchor nails 7;

[0034] The guardrail structure includes a base 1, internal cross bracing baffles, channel steel, upper double cross beams 2, and a bolt connection structure. The channel steel is installed inside the base 1. The lower base 1 is reinforced with internal cross bracing baffles and channel steel and connected by the first bolts 4. The guardrail structure can be installed by simply combining and connecting the double cross beams 2 with the first bolts 4 and fixing the base 1 with special anchor nails 7, thereby improving the installation efficiency of the guardrail structure.

[0035] Moreover, the base 1, the second inner horizontal support baffle 6 and the double crossbeam 2 are all assembled by connecting parts. When moving, the base 1, the second inner horizontal support baffle 6 and the double crossbeam 2 can be disassembled, thereby reducing the weight during movement. After moving to the installation position, the base 1, the second inner horizontal support baffle 6 and the double crossbeam 2 are assembled, thereby facilitating the movement of the steel guardrail structure.

[0036] The base 1 can be reinforced by the first internal cross-bracing baffle 5 and the second internal cross-bracing baffle 6, so that the base 1 will be supported by the first internal cross-bracing baffle 5 and the second internal cross-bracing baffle 6 when squeezed, thereby effectively avoiding deformation of the base 1 and improving the overall firmness of the steel guardrail structure.

[0037] See also Figure 2The upper surface of the base 1 and the corresponding positions of the second internal cross-bracing baffle 6 are both provided with mounting openings 8, and the special anchoring nails 7 pass through the mounting openings 8 and are connected to the surface of the second internal cross-bracing baffle 6. The second internal cross-bracing baffle 6 can be installed on the ground through the special anchoring nails 7.

[0038] See also Figure 5 Threaded holes 9 are evenly opened on the upper surface of the beam sleeve 3, and the first bolts 4 pass through the double beams 2 and are screwed into the inside of the threaded holes 9, so that two adjacent double beams 2 can be connected through the beam sleeve 3.

[0039] See also Figure 1 The upper surface of the bottom plate of the double cross beam 2 is evenly screwed with the second bolts 10, and the lower part of the second bolts 10 is connected to the surface of the base 1. The double cross beam 2 can be installed on the upper surface of the base 1 through the second bolts 10. The upper double cross beam 2 is connected to the lower base 1 of the outer shape with the second bolts 10. The second bolts 10 are high-strength M20*130 bolts.

[0040] The inner wall of the double crossbeam 2 is evenly installed with columns 11, see Figure 3 Drain holes 12 are evenly opened on both sides of the bottom of the base 1. The columns 11 can improve the firmness of the double beams 2. The drainage holes 12 can effectively solve the problem of water blocking at the bottom of the guardrail when the rainfall is heavy in the rainy season.

[0041] See also Figure 6 Fixing holes 13 are provided on both sides of the upper surface of the second internal cross bracing baffle 6, and the special anchoring nails 7 are screwed into the inner cavity of the fixing holes 13. Fixing rods 14 are screwed between the second internal cross bracing baffle 6 and the inner wall of the base 1. The second internal cross bracing baffle 6 can be installed in the base 1 through the fixing rods 14, which facilitates the installation of the second internal cross bracing baffle 6.

[0042] The standard inter-section of the double crossbeam 2 adopts the inner sleeve method and is connected with high-strength M20*150 bolts and Φ20 self-locking pins. Use M20 anchor bolts or special anchor nails 7 to fix the guardrail to the road surface. The cross brace baffles and cross brace channel steels are made of high-quality steel hot-dip galvanized plates, and the base 1, crossbeams, columns 11, and special anchor nails 7 are made of high-strength steel zinc-aluminum-magnesium coatings. The structures are combined and installed, with a simple structure and convenient and fast construction. The base 1 is 450mm high and has a drainage hole 12 at the bottom, which effectively solves the problem of water blockage at the bottom of the guardrail during heavy rainfall in the rainy season. It is a huge change in the traditional industry of mobile steel guardrails in construction areas.

[0043] The beams, columns 11, and base 1 are all constructed from high-strength steel with a zinc-aluminum-magnesium coating. This coating utilizes a new high-strength steel, S750HLD+ZMA. This coating significantly exceeds the strength of existing Q235B steel and offers numerous advantages, including excellent ductility, low-temperature toughness, plating suitability, and performance stability. Its mechanical properties include yield strength ≥700 MPa, tensile strength ≥750 MPa, and elongation ≥20%. This new high-strength steel improves its strength, cold bending properties, elongation, and low-temperature toughness, resulting in overall superior performance compared to traditional Q235B steel.

[0044] The coating is made of zinc-aluminum-magnesium ternary alloy coating, which has high corrosion resistance. Its corrosion resistance is more than three times that of pure zinc coating products with the same coating weight. The alloy element ions in the surface coating gradually cover the incision as the liquid film flows, forming a stable protective film, which significantly improves the corrosion resistance of the incision.

[0045] Cross brace baffles and cross brace channels are made of high-quality hot-dip galvanized SHG340 steel, a premium steel type developed by Nippon Steel. Its application market is diverse, and its performance far exceeds that of post-galvanized steel products of the same material. This reduces environmental pollution and carbon emissions.

[0046] The working process of this device is as follows: First, the main load-bearing components of the SB-level light high-strength zinc-aluminum-magnesium construction area movable guardrail are made of high-strength zinc-aluminum-magnesium materials, which have the characteristics of high protection level, light weight and high strength, fast construction, simple installation, convenient maintenance, and green and low-carbon. For each construction area movable guardrail, within the installation length of 42 meters, only the anchoring unit sections at the first and last ends need to be anchored. All standard unit sections only need to be spliced with crossbeam bolts and do not need to be anchored to the road surface. After the installation length exceeds 42 meters, anchor once every 42 meters, and only 3 embedded bolts are anchored on both sides of the center of the standard unit section at the 42-meter position. The SB-level light high-strength zinc-aluminum-magnesium construction area movable guardrail consists of anchoring unit sections at both ends and several standard unit sections. Each unit is 6m long. The implementation plan is as follows:

[0047] 1. Use the edge line of the construction area as the control point to perform distance measurement and positioning.

[0048] 2 Assemble the SB-grade lightweight high-strength zinc-aluminum-magnesium construction area movable guardrail components into guardrail units.

[0049] 3 Arrange the assembled guardrail units according to the layout line and connect them into a whole.

[0050] 4Adjust the line shape.

[0051] 5. Drill holes and plant rebar.

[0052] 6 Adjust the alignment again and tighten the bolts.

[0053] 7. Install anti-glare panels and stick reflective film.
