Description

Technical Field

[0001] This utility model relates to the technical field of traffic safety facilities in highway engineering, and in particular to a basalt multifunctional connecting bracket and integrated support system. Background Technology

[0002] Currently, highway anti-glare facility support systems are mainly made of steel or fiberglass. Steel supports are hot-dip galvanized or hot-dip galvanized with powder coating for corrosion protection and are widely used in early anti-glare facilities. For example, the steel anti-glare supports commonly used on highways in North China typically have a hot-dip galvanized layer thickness of 80-120μm, but they are still prone to rusting under the corrosive effects of de-icing agents and rainwater. In areas where de-icing agents are used, such as Inner Mongolia and the three northeastern provinces, the average annual corrosion rate of steel supports reaches 0.08mm, and large areas of red rust appear after 3 years. The service life on regular road sections is only 5-8 years, and on heavily corroded road sections, it is only 3-5 years.

[0003] Fiberglass brackets: Made of fiberglass and unsaturated resin, they are widely used in rainy southern regions. However, this material has no recycling value and is often disposed of as construction waste after removal. Approximately 200,000 tons of fiberglass anti-glare structures are removed annually in China, but only 1.2% can be crushed and used as roadbed filler; the rest is landfilled, resulting in resource waste and environmental pollution. This does not meet environmental protection requirements.

[0004] Currently, traditional anti-glare device support systems, such as the composite material anti-glare device support system disclosed in patent ZL201930268883.8, mainly consist of double or triple-layer hoist clamps, crossbeam connecting plates, crossbeam clamps, support columns, and H-beams. Taking a 4m unit as an example, a single system includes 4 clamps, 16 sets of bolts, and multiple connectors, resulting in a complex structure and cumbersome installation. For instance, the clamp structure is complex and inconvenient to maintain: the double or triple-layer hoist clamp design leads to numerous accessories. For example, in some areas of Xinjiang, the three-layer clamp system has the lower clamp only 5cm from the ground, resulting in a 32% damage rate during weeding operations and a weed coverage rate exceeding 20%. Installation efficiency is also low: a traditional system contains 16 sets of bolts per set, takes approximately 24 minutes to install, and requires multiple handling of accessories, resulting in long construction time and making it unsuitable for roads with high traffic volume.

[0005] The applicant has made beneficial explorations and attempts to address the technical problems and objectives of this invention, and has found a solution to the above problems. The solution to be introduced below is a product of this background. Utility Model Content

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the utility model will be further described below.

[0026] Please see Figure 1-2 As shown, this utility model embodiment discloses a basalt multifunctional connecting bracket, wherein the basalt multifunctional connecting bracket is a composite material composed of basalt fiber, unsaturated resin and calcium powder, integrally molded by SMC sheet molding compound, and the internal stress is eliminated by post-curing treatment.

[0027] The main structure of the basalt multifunctional connecting bracket includes a crossbeam mounting groove 10, a plate-shaped connecting part 40, and a cylindrical insertion part 50. The crossbeam mounting groove 10 is formed by two side walls 20 and a groove bottom 30 to form a U-shaped structure. It is 220mm long, with two side walls 10mm thick, a groove bottom 10mm thick, a groove opening width of 53mm, a groove bottom width of 25mm, and a groove depth of 71mm. The two side walls are provided with through bolt channels 21 with a diameter of 12mm and a channel spacing of 130mm.

[0028] The plate-shaped connecting part 40 extends outward from both sides of the groove, and the plate surface is provided with four circular mounting holes 41, with arc-shaped clearance notches 42 machined at the edges. In this embodiment of the utility model, triangular stiffening plates 60 are provided between the plate-shaped connecting part 40 and the two outer side walls of the crossbeam mounting groove 10.

[0029] The cylindrical insertion part 50 is vertically fixed to the center of the bottom of the groove. It is a hollow cylindrical structure with a height of 60mm and an axial anti-rotation protrusion 51 on the inner wall.

[0030] Please combine Figure 3-6As shown, this utility model embodiment also discloses a basalt multifunctional connecting bracket integrated support system, including a basalt multifunctional connecting bracket, and also including a crossbeam 80 and a component to be connected. The crossbeam 80 is installed in the crossbeam mounting groove 10 and connected to the basalt multifunctional connecting bracket through the bolt hole 21 and bolts. The components to be connected include functional components and structural components: functional components include, for example, anti-glare panels 10 and signs; structural components include, for example, guardrail posts 100, support posts 70, and single-layer double-cavity gourd-shaped clamp components 110; the single-layer double-cavity gourd-shaped clamp component 110 has two annular hollow chambers, a large one and a small one, which are rigidly connected by a middle cross arm 113; the guardrail post 100 is connected to the single-layer double-cavity gourd-shaped clamp component 110 through the large chamber 111. The supporting column 70 is connected to the gourd-shaped clamp component through the small chamber 112. A bracket structure 120 is provided below the intersection of the large and small chambers and the cross arm 113 of the single-layer double-chamber gourd-shaped clamp component 110. The bracket structure 120 is integrally molded with the clamp body using SMC. The bracket structure 120 includes a supporting part 121 and a fitting part 122. The supporting part 121 fits against the lower surface of the cross arm 113 to distribute the force on the cross arm 113. The fitting part 122 fits against the outer walls of the large and small chambers to enhance structural stability. The measured bending load of the clamp arm meets the design requirement of ≥8500N. In this embodiment, the large chamber 111 is adapted to the guardrail post 100; the small chamber 112 is adapted to the supporting column 70; the two chambers are connected by the intermediate cross arm 113. The openings of the large and small chambers are provided with clamp bolt holes 114, and the clamp and the column are fastened by bolt locking.

[0031] Detailed installation steps of this utility model embodiment: Bolt installation: During installation, all bolts should have their outer hexagonal prongs facing the same direction, i.e., the direction of vehicle travel, with the outer hexagonal prongs on top and the nut on the bottom, to ensure the consistency of the bolt orientation.

[0032] The single-layer double-cavity gourd-shaped clamp component 110 is fixed to the guardrail post 100: The large chamber of the single-layer double-cavity gourd-shaped clamp component 110 is tightly fastened to the lower edge of the guardrail post 100, leveled, and the bolt is inserted into the bolt hole, with the bolt washer placed in and the nut tightened.

[0033] Installation of support column 70: Tightly fasten the small chamber 112 of the single-layer double-cavity gourd-shaped clamp component 110 to the support column 70, insert the bolt into the bolt hole, put in the bolt washer and tighten the nut.

[0034] Connecting bracket assembly: The cylindrical insert part 50 of the connecting bracket is fitted onto the top of the support column 70, and the inner wall protrusion 51 is aligned with the groove of the support column 70.

[0035] Fixing the H-beams: The two ends of the H-beam 80 are inserted into the H-beam mounting slots 10 of the connecting bracket. Bolts are inserted through the bolt holes 21 on both side walls and tightened to the pre-drilled holes on the side of the H-beam 80. Two H-beams 80 need to be fixed on one connecting bracket. Traditional H-beams are held in place by a connecting plate and clamps, which are prone to detachment due to strong winds and varying column spacing. This optimized design involves drilling holes in the side walls of the new connecting bracket and the side of the H-beam. The H-beam is placed inside the bracket, and then two bolts are used to tighten the connecting bracket and the H-beam together, ensuring it does not detach.

[0036] Installation of the first anti-glare panel 10: The base of the anti-glare panel is placed on the top surface of the connecting bracket plate-shaped connecting part 40, and is connected and fixed to the plate-shaped connecting part 40 by a pair of L-shaped connectors 130.

[0037] Installation of subsequent anti-glare panels 10: Using a steel tape measure, measure a position 2m along the direction of the crossbeam, starting from the first anti-glare panel 10, and mark it with a marker. Insert the connecting bracket upwards from the bottom of the H-beam 80, ensuring the mark is centered on the connecting bracket. Then, using a pair of L-shaped connectors 130, align the bolt holes, insert the bolts, and insert washers and nuts to tighten, ensuring the anti-glare panel 10 stands upright. The following is a material list for the basalt multi-functional connecting bracket integrated support system.

[0038] 1 Anti-glare panel 900*280 piece 2 2 Connecting bracket 220*120*7 piece 1 3 Daily character crossbeam 3960*50*70 piece 1 4 Supporting column 70 Ø70*350 piece 1 5 Hoop 530*60 piece 2 As can be seen from the comparison, a traditional FRP (fiberglass reinforced plastic) anti-glare device support system requires 4 clamps, 1 support column (70mm), 1 crossbeam connecting plate, 2 crossbeam clamps, 1 H-beam, and 16 sets of bolts. The support system structure is relatively complex and uses a lot of materials. However, with the new bracket, a complete basalt anti-glare device support system is reduced to 2 clamps, 1 support column (70mm), 1 connecting bracket, 1 H-beam, and 6 sets of bolts. Installation is simpler and saves on installation materials.

[0039] Adaptive adjustments for different operating conditions: The inner wall of the cylindrical plug part 50 can be replaced with an internal thread structure, which can be screwed into the support column 70 with external threads, making it suitable for scenarios that require frequent disassembly.

[0040] II. Size Optimization Scenarios If there is a deviation in the spacing of the guardrail posts 100, the bolt holes at the opening of the large cavity 111 of the clamp can be changed to waist-shaped elongated holes, allowing for a certain amount of adjustment.

[0041] Implementation effect verification

[0042] Installation efficiency: An 8-person team can install 1.3km of anti-glare facilities per day, which is 30% higher than traditional systems.

[0043] Convenience of maintenance: The single-layer double-cavity gourd-shaped clamp component 110 is more than 30cm above the ground. Compared with the traditional double-layer clamp which is close to the ground, it is more convenient for maintenance workers to carry out weeding operations inside the guardrail.
