Description

Technical Field

[0001] The utility model relates to the technical field of traffic greening, in particular to a top-mounted flower box supporting device for a viaduct guardrail. Background Art

[0002] As cities continue to expand, there are more and more elevated road systems in cities. Elevated road systems can effectively alleviate traffic congestion problems, and they also have the characteristics of multiple interchange levels, large traffic flow, and difficulty in disconnecting. Elevated bridges are often congested and slow in peak hours in the morning and evening. In addition, concrete wall guardrails must be installed on both sides of the elevated bridges, and there are dense buildings on both sides, so the driver's driving visual landscape is relatively monotonous.

[0003] At present, the concrete wall guardrails on both sides of the viaducts in most cities are not greened. There are many factors to consider when adding greening to the viaducts that have been built and opened to traffic. First, the difficulty of high-altitude operations is high and the safety risk of greening devices at high altitude is high. Second, the load of the bridge is limited, and the structural device should use materials with lighter weight. Third, the traffic flow should be ensured to shorten the construction impact time as much as possible. Fourth, the outdoor environment should pay attention to structural corrosion. The existing guardrail top greening mainly includes two types of flower boxes: top-mounted and external-mounted. The external-mounted flower box is blocked by the concrete guardrail, and the effect is not as good as the top-mounted flower box during the peak flowering period. Most of the top-mounted flower boxes use specially customized flower boxes. The flower boxes are anchored into the reinforced concrete guardrail through steel bars to achieve the anchor connection between the flower box and the guardrail. Some flower boxes directly purchase finished flower pots, and the flower pot support structure is welded with flat iron bars. The existing technology has a single fixing method, and the welding process is difficult to control. The welding points are prone to rust, the supporting structure has the hidden danger of damage, and the flower pots have the risk of falling, which poses a safety threat to the driving and pedestrians on the viaduct.

[0004] Therefore, in order to effectively shorten the construction time and enhance the fixing effect of the flower pots, the utility model proposes a top-mounted flower box supporting device for an elevated bridge guardrail. Utility Model Content

[0005] The utility model aims to solve the deficiencies of the prior art and provides a top-mounted flower box supporting device for an elevated bridge guardrail.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A top-mounted flower box support device for an elevated bridge guardrail comprises two supporting side walls, a connecting device connecting the two supporting side walls as one, a flower pot support beam arranged on the inner side of the middle section of the two supporting side walls, and a fixing device connecting the two supporting side walls to a crash barrier and a crash barrier wall respectively, wherein the supporting side walls, the connecting device, the flower pot support beam and the fixing device are all treated with rust prevention;

[0008] The connecting device includes an upper connecting beam and a lower connecting beam. The upper connecting beam is arranged at both ends of the top of the supporting side wall. The lower connecting beam is arranged between the flowerpot supporting beam and the bottom of the supporting side wall. The bottoms of the two supporting side walls are sleeved with the top of the anti-collision wall, and the lower connecting beam is placed at the top end of the anti-collision wall.

[0009] Preferably, the supporting side wall includes two horizontally arranged upper cross beams and lower cross beams, and two vertically arranged left columns and right columns. The upper cross beam, the lower cross beam, the left column and the right column enclose a rectangular frame. The upper cross beam and the lower cross beam are arranged in the upper sections of the left column and the right column. The upper cross beam, the lower cross beam, the left column and the right column are connected by connecting bolts.

[0010] Preferably, a plurality of reinforcing beams and reinforcing columns are arranged on the outer side of the supporting side wall.

[0011] Preferably, the fixing device includes a guardrail fixing device arranged between the flowerpot supporting beam and the lower connecting beam, and chemical anchor bolts arranged at the lower connecting beam and the bottom of the supporting side wall.

[0012] Preferably, the guardrail fixing device includes a guardrail fixing beam arranged at the lower end of the flowerpot supporting beam and a clamp detachably connected to the guardrail fixing beam.

[0013] Preferably, a support block is arranged between the guardrail fixing device and the lower connecting beam, and the support block is U-shaped.

[0014] Preferably, a housing is arranged on the outer side of the supporting side wall.

[0015] Preferably, the upper connecting beam, the lower connecting beam and the flowerpot supporting beam are all U-shaped.

[0016] The top-mounted flower box support device for a viaduct guardrail disclosed by the present utility model has the following beneficial effects.

[0017] First, by arranging a fixing device on the supporting side wall, the fixing device includes a guardrail fixing device and chemical anchor bolts. The anti-collision railing is fixed to the guardrail fixing beam through a clamp, and then the guardrail fixing beam is fixed to the supporting side wall through a connecting bolt. The bottoms of the two supporting side walls are sleeved with the top of the anti-collision wall, and the supporting side wall bottom is fixed to the anti-collision wall through chemical anchor bolts. By arranging chemical anchor bolts on the lower connecting beam, the fixing effect between the supporting side wall and the anti-collision wall is further enhanced, which can ensure the stability of the flower box, effectively reduce the risk of flowerpot falling, maximize the protection of traffic safety, and reduce the safety threat to vehicles and pedestrians.

[0018] Second, the present utility model uses lightweight and rust-proof materials, which reduces the self-weight of the entire support structure, reduces the influence on the viaduct load, and ensures the structural safety of the bridge. Description of the Drawings

Embodiment

[0030] A top-mounted flower box support device for a viaduct guardrail, which is used in the scenario where the top width of the concrete guardrail is 230 mm and the size of the finished flower box is 800×321×290 mm.

[0031] Refer to Figure 1 and Figure 2 As shown, a top-mounted flower box support device for a viaduct guardrail includes two support side walls 1, a connecting device 3 that connects the two support side walls 1 into one body through connecting bolts 2, a flower pot support beam 4 provided inside the middle sections of the two support side walls 1, and a fixing device 5 that connects the two support side walls 1 to the anti-collision railing 100 and the anti-collision wall 200 respectively. At least 3 flower pot support beams 4 are provided under each flower pot. The minimum distance between the tops of the two support side walls 1 is 321 mm, and the minimum distance between the bottoms of the two support side walls 1 is 230 mm. The support side walls 1, the connecting device 3, the flower pot support beam 4, and the fixing device 5 are all treated with rust prevention. Specifically, as Figure 3 shown, the support side wall 1 includes two horizontally arranged upper cross beams 11 and lower cross beams 12, and two vertically arranged left columns 13 and right columns 14. The upper cross beam 11, the lower cross beam 12, the left column 13, and the right column 14 enclose a rectangular frame. The upper cross beam 11 and the lower cross beam 12 are arranged in the upper sections of the left column 13 and the right column 14. The upper cross beam 11, the lower cross beam 12, the left column 13, and the right column 14 are connected by connecting bolts 2. The connecting bolts 2 are of the M4×20 mm model. The upper cross beam 11, the lower cross beam 12, the left column 13, and the right column 14 are made of galvanized flat iron with a size of 40×4 mm. The flat iron is made of Q235B grade steel. Using flat iron (Q235 B grade steel) as the main structural material has a certain elongation rate, strength, good toughness and castability, and is easy to stamp and weld. Compared with using stainless steel, it can save a large amount of cost and reduce the construction cost. The connection points are pre-drilled. In this embodiment, the lengths of the upper cross beam 11 and the lower cross beam 12 are 850 mm, and the lengths of the left column 13 and the right column 14 are 770 mm. The upper cross beam 11 is installed at the tops of the left column 13 and the right column 14, and the lower cross beam 12 is installed 280 mm from the top to the bottom of the left column 13 and the right column 14. The distance between the bottom ends of the left column 13 and the right column 14 and the top of the anti-collision wall 200 is 150 mm. A 4-mm-thick flat iron strip is used as the structural framework. Compared with the usually used iron plate to enclose the flower box, it can greatly reduce the weight of the flower rack itself, and at the same time has a certain flexibility and can better adapt to the inconsistent sizes of the anti-collision wall 200. The flower pot support beam 4 is installed on the lower cross beam 12.

[0032] As Figure 2 shown, the connecting device 3 includes an upper connecting beam 31 and a lower connecting beam 32. The upper connecting beam 31 is arranged at both ends of the top of the support side wall 1 through M4×20 mm connecting bolts 2, specifically installed at the tops of the left column 13 and the right column 14. The lower connecting beam 32 is arranged between the flower pot support beam 4 and the bottom of the support side wall 1 through M4×20 mm connecting bolts 2. As Figure 4and Figure 6 As shown in Figure 6 , the bottoms of the two support side walls 1 are sleeved with the tops of the anti-collision wall 200, and the lower connecting beam 32 is placed at the top end of the anti-collision wall 200. As Figure 5 shown in Figure 5 , the upper connecting beam 31 and the lower connecting beam 32 are also made of galvanized flat iron with a size of 40×4 mm, and the upper connecting beam 31 and the lower connecting beam 32 are U-shaped. The fixing device 5 includes a guardrail fixing device 51 arranged between the flower pot support beam 4 and the lower connecting beam 32 through an M4×20 mm connecting bolt 2, and chemical anchor bolts 513 arranged at the bottom of the lower connecting beam 32 and the support side wall 1; the chemical anchor bolt 513 of the lower connecting beam 32 is an M8×110 mm chemical bolt anchor, and the chemical anchor bolt 513 at the bottom of the support side wall 1 is an M12×250 mm through-length chemical bolt. The M12×250 mm through-length chemical bolt penetrates the anti-collision wall 200 for anchoring. The guardrail fixing device 51 includes a guardrail fixing beam 511 arranged at the lower end of the flower pot support beam 4 and a clamp 512 detachably connected to the guardrail fixing beam 511. The guardrail fixing beam 511 is a U-shaped galvanized flat iron with a size of 40×4 mm, and the size of the hoop is 40×2 mm. In this embodiment, by arranging the fixing device 5 on the support side wall 1, the fixing device 5 includes a guardrail fixing device 51 and chemical anchor bolts 513. The anti-collision railing 100 is fixed to the guardrail fixing beam 511 through the clamp 512, and then the guardrail fixing beam 511 is fixed to the support side wall 1 through the connecting bolt 2. The bottoms of the two support side walls 1 are sleeved with the tops of the anti-collision wall 200, and the bottom of the support side wall 1 is fixed to the anti-collision wall 200 through the chemical anchor bolts 513. By arranging the chemical anchor bolts 513 on the lower connecting beam 32, the fixing effect between the support side wall 1 and the anti-collision wall 200 is further enhanced, which can ensure the stability of the flower box, effectively reduce the risk of flower pots falling, maximize the protection of traffic safety, and reduce the safety threat to vehicles and pedestrians.

[0033] In this embodiment, in order to strengthen the stability of the support side wall 1, a plurality of strengthening beams 15 and strengthening columns 16 are arranged on the outer side of the support side wall 1. The strengthening beams 15 and strengthening columns 16 are square tubes with a size of 20×20×2 mm; for aesthetics, a 1.5 mm aluminum plate flower box shell 6 is fixed to the outer sides of the strengthening beams 15 and strengthening columns 16 through galvanized self-tapping screws, and the aluminum plate surface is powder-coated with a paint color similar to the anti-collision color.

[0034] Please refer to Figure 4 and Figure 6 , in this embodiment, an installation space for the drain pipe 300 and the water supply pipe 400 is reserved. In order to improve the installation stability of the drain pipe 300, a U-shaped support block 7 is arranged between the guardrail fixing device 51 and the lower connecting beam 32 through an M4×20 mm connecting bolt 2. In order to avoid the inconsistent heights of the top ends of the anti-collision wall 200, as Figure 8 shown in Figure 8 , the installation holes for installing the lower connecting beam 32 are waist-shaped holes. As Figure 7As shown, due to the existence of the bridge expansion joint 500, in order to facilitate installation and prevent the influence of thermal expansion and contraction on the stability of the support device, the distance between the two support devices is not less than 50 mm when encountering the bridge expansion joint 500.

[0035] The above is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. The substitution can be the substitution of part of the structure, device, and method steps, or the complete technical solution. Any equivalent substitution or change made according to the technical solution and the inventive concept of the present invention should be covered within the protection scope of the present invention.
