For example, if a bridge crosses an existing urban road, a safety shed must be erected before the construction of the crash barriers to ensure the safety of vehicles traveling under the bridge.
[0003] Currently, the construction of crash barriers for cross-road bridges mainly adopts a combination of steel pipe columns and Bailey beams (steel sections) to form a protective canopy by laying steel plates on the support. The construction of the safety canopy requires a lot of materials, and the project cost is relatively high. At the same time, the traffic flow is large, and the coordination of traffic diversion work during the construction of the protective canopy is difficult. This protection method has a long construction period.
[0004] Therefore, this utility model provides a safety protection device for the construction of bridge anti-collision guardrails, which can solve the problems in the prior art that the construction of protective sheds requires a lot of materials, which increases the project cost, and the construction period is long due to traffic diversion, thereby reducing construction costs and shortening the construction period.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model.

[0024] Reference Figures 1-5As shown, this utility model provides a safety protection bottom support device for the construction of bridge crash barriers. The safety protection bottom support device for the construction of bridge crash barriers includes a crash barrier steel template 1, a protective frame, and a fixing component 3. The fixing component 3 is fixedly connected between the crash barrier steel template 1 and the protective frame. The surface of the crash barrier steel template 1 is provided with stiffening plates 2, which are evenly distributed in the horizontal direction. The crash barrier steel template 1 is connected to the fixing component 3 through the stiffening plates 2, and the distance between adjacent stiffening plates 2 is between 25cm and 35cm. The protective frame includes several hanging rods 4, several bottom support crossbars 5, and bamboo plywood 6. The hanging rods 4 are also evenly distributed in the horizontal direction, and the top of the hanging rods 4... One side of the upper part is fixedly connected to the steel template 1 of the crash barrier via a fixing component 3, and the bottom is fixedly connected to one end of the bottom support crossbar 5. The spacing between adjacent hanging rods 4 / bottom support crossbars 5 is between 50cm and 70cm, and the diameter of the bottom support crossbar 5 is between 12mm and 16mm. The bamboo plywood 6 is fixedly connected to the top surface of the bottom support crossbar 5, and the thickness of the bamboo plywood 6 is between 15mm and 20mm. The fixing component 3 includes a welded flat iron 301, a fixing bolt 302, and a nut 303. The welded flat iron 301 is welded to the top side of the hanging rod 4. The fixing bolt 302 passes through both the welded flat iron 301 and the crash barrier. The nut 303 is threadedly connected to the tail of the fixing bolt 302.
[0025] It should be noted that, in this embodiment, the steel template 1 of the crash barrier serves as the supporting structure of the bridge crash barrier. The stiffening plates 2 of the steel template 1, arranged at equal intervals in the horizontal direction, ensure the stability and supporting strength of the bridge crash barrier. The protective frame is designed to protect personnel or materials during construction, preventing accidental falls. Specifically, the protective frame includes hanging rods 4, bottom supporting crossbars 5, and bamboo plywood 6. The hanging rods 4 bear the weight of the protective frame and are fixedly installed with the stiffening plates 2 of the crash barrier template. The design of the hanging rods 4, with their equal-interval distribution, ensures... The protective frame is subjected to uniform force to enhance its structural stability. The bottom support crossbar 5 acts as a lateral support within the protective frame, and its fixation to the hanger 4 allows the protective frame to withstand certain external forces. It is used to prevent construction personnel or materials from falling from the bottom of the protective frame and provides a working surface for construction workers. The fixing component 3 is used to fix the anti-collision guardrail steel template 1 to the protective frame, ensuring the stability of the entire safety protection bottom support device used for bridge anti-collision guardrail construction, preventing the protective frame from loosening or shifting during construction. Specifically, the fixing component 3 includes a welded flat... The design of the iron 301, fixing bolt 302, and nut 303 facilitates the installation and disassembly of the protective frame and the stiffening plate 2 of the anti-collision guardrail steel template 1, enabling the reuse of the protective frame after construction. In the specific implementation of this utility model, the safety protection bottom support device for bridge anti-collision guardrail construction forms a safety protection bottom support structure through the design of the hanging rod 4, the bottom support crossbar 5, and the bamboo plywood 6. The design of welding the flat iron 301, fixing bolt 302, and nut 303 forms a detachable and stable structure between the protective frame and the stiffening plate 2 of the anti-collision guardrail steel template 1. Support structure: Compared with the existing technology of using a combination of steel pipe columns and Bailey beams (steel sections) to form a protective shed by laying steel plates on the support structure, this solution is simpler in structure and easier to erect. Moreover, after construction is completed, the protective frame can be disassembled and moved to the next section of the crash barrier for protection, reducing manufacturing costs. The protective frame structure in the above design can provide workers with a construction operation surface close to the steel formwork 1 of the crash barrier. During construction, there is no need to clear traffic under the bridge, which is much easier than the existing technology where the construction of the protective shed involves a lot of coordination difficulties in traffic diversion. Therefore, this utility model can reduce construction costs and shorten the construction period.
[0026] Reference Figure 3 and Figure 4 As shown, the bottom support crossbar 5 is U-shaped, and the bamboo plywood 6 is also U-shaped; the outer side of the bamboo plywood 6 is attached to the inner side of the bottom support crossbar 5.
[0027] It should be noted that, in this embodiment, the U-shaped design of the bottom support crossbar 5 can effectively withstand forces from above, below, or to the side, and provides a larger contact area to enhance the supporting force between the bottom support crossbar 5 and the hanging rod 4, preventing the bottom support crossbar 5 from deforming or becoming unstable. In addition, the U-shaped design of the bottom support crossbar 5 can also hold the bamboo plywood 6 fixed at the top, preventing the bamboo plywood 6 from shifting or falling off in a direction away from the hanging rod 4, thus ensuring the safety of the protective frame. The U-shaped design of the bamboo plywood 6 can match the shape of the bottom support crossbar 5, allowing it to better fit and tightly adhere to the inner side of the support crossbar 5, thereby increasing the supporting force and stability of the bamboo plywood 6 and preventing the bamboo plywood 6 from shifting or falling off during construction.
[0028] The safety protection device for bridge crash barrier construction also includes a plastic sheet, which is laid on the inside of the bamboo plywood 6.
[0029] It should be noted that in this embodiment, the concrete is fluid during the pouring process, and is prone to overflow or leakage, especially before it is completely solidified. The plastic sheet laid on the bamboo plywood 6 can effectively prevent the concrete from flowing out of the construction area.
[0030] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
