Description

Technical Field

[0001] The invention relates to the technical field of tools for bridge guardrail construction, in particular to a bridge guardrail template top protection railing. Background Art

[0002] When pouring concrete for bridge guardrails, construction workers need to first install casting molds on both sides of the bridge along the length of the bridge, and then pour concrete into the casting molds. After the concrete pouring is completed, construction workers insert vibrating rods into the templates to vibrate; Since the casting mold is high and the opening is facing upward, the construction workers need to climb above the casting mold when vibrating the concrete. However, most bridges are constructed at high altitude, and the outer side of the bridge guardrail is in an air-free state. The construction workers stand on the casting mold to vibrate without any safety measures, which can easily cause safety accidents. To solve this problem, the traditional approach is to use fasteners, steel plates and steel pipes to set up temporary railings on the outer side of the bridge guardrail. The steel plates are connected to the casting mold by fasteners, and the construction workers stand on the steel plates to construct. With this method, when the construction workers vibrate the concrete, they need to repeatedly remove and install the railings on the casting mold along the length direction of the casting mold, which wastes time and affects the construction progress. Summary of the invention

[0003] The invention provides a bridge guardrail template top protective railing, which can overcome certain or some defects of the prior art.

[0005] When the loader is standing on the mounting plate, the mounting plate is pressed against the mounting plate, and the mounting plate is moved downwards, thereby pushing the lifting column to pass through the limiting hole on the mounting plate and move downwards. After the mounting plate and the lifting column move downwards, the clamping plate on the mounting plate will be clamped on the outer edge of the casting mold, and the inner side of the casting mold will be pressed against the mounting plate, and the mounting plate will be limited by the connecting plates on both sides of the mounting plate on the casting mold, thereby preventing the mounting plate and the casting mold from being separated from the casting mold when the loader is standing on the mounting plate, and preventing the mounting plate from shaking when the loader is walking, thereby affecting the construction safety of the loader. After a section of concrete in the casting mold is vibrated, the construction workers get off the mounting plate. After the construction workers leave the mounting plate, the first spring pushes the first lifting plate to move up, thereby moving the lifting column up, driving the mounting plate to move up, and after the mounting plate moves up, the mounting plate is separated from the limit of the connecting plate, and the clamping plate on the mounting plate is separated from the casting mold. Then the construction workers pull the mounting seat to move the mounting seat away from the casting mold, and then push the mounting seat to the next vibration position at the casting mold, and finally repeat the above steps to complete the vibration of the concrete.
