Description

Technical Field

[0001] The utility model relates to the technical field of bridge engineering, and specifically relates to a snow-falling prevention device suitable for a fully enclosed sound barrier of a bridge. Background Art

[0002] In cold winter, especially in areas with frequent snowfall, a large amount of snow often accumulates on the existing fully enclosed sound barriers of viaducts. When the snow accumulates to a certain extent, the snow may slide down the sound barriers, causing damage to the vehicles below, and even threatening the safety of passengers, drivers and pedestrians, causing great impact on roads and traffic. The sliding of a large amount of snow may also cause traffic jams or accidents, which has an adverse impact on traffic flow and road safety.

[0003] In order to avoid hidden dangers, the existing fully enclosed sound barriers can only be cleared of snow regularly. The viaduct is tens of meters high, and the cleaning work is very difficult to carry out. The limited cleaning working surface is also prone to scratches and damage to the bridge body and the sound barrier, and may cause traffic congestion, thereby consuming a lot of manpower and material resources. Therefore, we propose an anti-snowfall device suitable for fully enclosed sound barriers on bridges. Utility Model Content

[0006] Preferably, a fixing structure is provided on the upper surface of the baffle, and the fixing structure includes a concave plate, the lower surface of the concave plate is fixedly connected to the upper surface of the square steel tube, the inner cavity of the concave plate is fitted with the side wall of the baffle, the upper surface of the concave plate is symmetrically threaded with a screw, and the side wall of the screw is threadedly connected with the baffle and the square steel tube in turn.

[0007] Preferably, the number of the baffles is three, and they are vertically arranged in sequence.

[0008] Preferably, the side wall of the steel support upright is fixedly connected with a through-hole plate, and the surface of the through-hole plate is evenly provided with through holes.

[0009] Preferably, the baffle is in a reverse Z-shape.

[0010] Compared with the prior art, the beneficial effects of the utility model are: through physical blocking, it effectively prevents snow from sliding off the sound barrier, which greatly reduces the risk of traffic accidents caused by snow sliding, thereby ensuring the safety of road traffic, and the structure is stable and durable. If the device is made of high-strength and corrosion-resistant materials, it can better ensure that it can remain stable and not easily damaged under various severe weather conditions. In addition, its structural design has also been carefully optimized to ensure that it can remain stable when subjected to snow pressure and wind and snow impact. The device is easy to install and maintain and can be quickly deployed at the required location. At the same time, due to its clear structure and modular design, daily maintenance and inspection also become relatively easy. Considering its long life, low maintenance cost and efficient anti-snowfall effect, the baffle-type anti-snowfall device has high cost-effectiveness in long-term use. It can not only reduce traffic accidents and property losses caused by snow sliding, but also reduce maintenance costs, bring practical economic benefits to road managers, greatly reduce manpower and material consumption, and reduce damage to the bridge body and sound barriers caused by snow.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-5 The utility model provides an anti-snowfall device suitable for a fully enclosed sound barrier of a bridge, including a steel column 1 and a steel curved beam 2. The lower surface of the steel curved beam 2 is symmetrically fixedly connected with the steel column 1, and the steel curved beam 2 and the steel column 1 form a complete fully enclosed sound barrier. The upper surface of the steel curved beam 2 is symmetrically fixedly connected with a steel support base plate 3. The upper surface of the steel support base plate 3 is fixedly connected with a steel support plate 4, the inner cavity of which is fixedly connected with a square steel pipe 5, and the outer wall of the square steel pipe 5 is fixedly connected with a baffle 6.

[0019] The steel column 1 and the steel curved beam 2 form a complete and fully enclosed sound barrier. A mirror-image steel support base plate 3 is installed at both ends of each group of steel curved beams 2. A steel support plate 4 is arranged on the surface of the steel support base plate 3. The steel support base plate 3 and the steel support plate 4 are welded together with steel plates. The steel support base plate 3 and the steel curved beam 2 are connected by bolts. A square steel pipe 5 is arranged in the inner cavity of the steel support plate 4. Each steel support plate 4 is welded and connected by a square steel pipe 5. Baffles 6 are installed on the square steel pipe 5 at equal intervals. The baffles 6 are thick steel plates in reverse Z shape and are connected to the square steel pipe 5 every 100 mm along the longitudinal direction of the bridge to prevent the accumulated snow from sliding to both sides along the slope of the ceiling of the fully enclosed sound insulation screen. Through physical blocking, the accumulated snow is effectively prevented from sliding off the sound barrier, thereby avoiding vehicle damage, traffic jams and even casualties caused by falling snow. The anti-snowfall device can effectively improve the safety of the road below the viaduct sound barrier.

[0020] A fixing structure 7 is provided on the upper surface of the baffle 6, and the fixing structure 7 includes a concave plate 71. The lower surface of the concave plate 71 is fixedly connected to the upper surface of the square steel tube 5, and the inner cavity of the concave plate 71 fits with the side wall of the baffle 6. The upper surface of the concave plate 71 is symmetrically threaded with screws 72, and the side walls of the screws 72 are threadedly connected with the baffle 6 and the square steel tube 5 in sequence. When installing the baffle 6, the baffle 6 can be inserted into the inner cavity of the concave plate 71, and the concave plate 71 is used to increase the limit, and the screws 72 penetrate and tighten it at the same time, so that the baffle 6 has a disassembly function. The baffle 6 can be disassembled in summer to reduce the load of the fully enclosed sound barrier.

[0021] There are three baffles 6 , which are arranged vertically in sequence.

[0022] The side wall of the steel support upright 4 is fixedly connected with a through-hole plate 8, and through-holes are evenly arranged on the surface of the through-hole plate 8. The through-hole plate 8 assists the baffle plate 6 to work, thereby improving the interception efficiency. When the accumulated snow melts, it can be discharged through the through-holes of the through-hole plate 8 without affecting the normal drainage effect.

[0023] The baffle 6 is in a reverse Z-shape.
