Description

Technical Field

[0001] This utility model relates to the field of construction safety, specifically to a device for preventing concrete pouring of crash barriers from falling off. Background Technology

[0002] During the construction of concrete crash barriers for bridges, concrete is usually transported by pumping trucks or unloading tank trucks. However, in practice, due to the narrow opening at the top of the formwork, concrete is prone to spillage during pouring. This not only wastes materials and increases construction costs, but may also pose a threat to the safety of people under the bridge, creating a significant safety hazard.

[0003] Existing concrete pouring protection facilities typically consist of a hopper, a guide pipe, and a support rod. By placing the hopper at the top of the guide pipe and the support rod above the guardrail template, the problems of the pouring opening being too small and the hopper requiring manual support are solved. However, these simple pouring protection facilities have significant shortcomings in terms of ease of movement, adaptability to different templates, and comprehensive prevention of concrete spillage. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a device to prevent concrete from falling during the pouring of crash barriers, which solves the problems of concrete spillage, material waste, and safety hazards during the construction of concrete crash barriers.

[0005] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0006] A device for preventing concrete pouring and falling off a crash barrier includes a first baffle, a second baffle, and two side baffles. The two side baffles are arranged parallel to each other. The first side of each side baffle is connected to two parallel side edges of the first baffle, and the second side edges of each side baffle are connected to two parallel side edges of the second baffle. The first baffle, the second baffle, and the two side baffles together form a concrete diversion cavity.

[0007] This invention utilizes a concrete flow guide cavity formed by a first baffle, a second baffle, and two side baffles to guide the flow direction of the concrete, prevent spillage during pouring, reduce material waste, improve construction efficiency, and avoid safety hazards.

[0008] Preferably, the top height of the connection point between the side baffle and the first baffle and the second baffle is the same as the top height of the first baffle and the second baffle, respectively; the first baffle is located near the inner side of the crash barrier template, and the second baffle is located near the outer side of the crash barrier template; the bottoms of the first baffle and the second baffle are flush, and the vertical height of the first baffle is lower than that of the second baffle.

[0009] This invention designs the vertical height of the first baffle placed near the inner side of the crash barrier template to be lower than the vertical height of the second baffle placed near the outer side of the brick guardrail template. The surface of the side baffle is the shape of the device, and the upper end of the device is designed as a downward sloping surface. This not only facilitates the construction operation of the workers, but also reduces the probability of concrete spilling onto the outer side of the crash barrier template during the pouring process.

[0010] Preferably, the first baffle has two through holes of equal horizontal height at a position slightly below the center, and the second baffle has two through holes of equal horizontal height at a position slightly below the center. The through holes on the first baffle and the second baffle form two pairs of opposing through holes. Each pair of through holes has a rotating shaft that passes through the first baffle and the second baffle, and rolling elements are provided at both ends of the rotating shaft.

[0011] This invention utilizes a rotating shaft and rolling elements to form a roller. The rolling elements contact the flat steel plate at the top of the crash barrier template, allowing the entire device to move smoothly on top of the crash barrier template. This facilitates construction personnel in adjusting the overall position of the device according to pouring requirements.

[0012] Preferably, the bottom of the first baffle and the bottom of the second baffle extend out of the bottom of the side baffle, and the extended portions form a pair of limiting plates.

[0013] With this invention, when the device is placed on the anti-collision guardrail template, the limiting plate can be inserted into the reserved groove at the bottom of the template to limit the device and prevent it from overturning during the pouring process, thus ensuring the stability of the construction process.

[0014] Preferably, the bottom surface of the limiting plate is lower than the horizontal plane where the lowest point of the rolling element is located.

[0015] With this invention, when the device is placed on the anti-collision guardrail template, the rolling element contacts the flat steel plate at the top of the anti-collision guardrail template, and the bottom surface of the limiting plate is lower than the lowest point of the rolling element, thereby improving the limiting effect of the limiting plate and ensuring the stability of the device during movement.
