Description

Technical Field

[0001] The utility model relates to the technical field of cap beam pad stone construction, in particular to a pre-buried cap beam pad stone construction safety guardrail. Background Art

[0002] The construction of slabs is very dangerous. Bridges are built to cross obstacles, so the slabs are located very high. The construction space for slabs is small, there is no place to wear a safety belt, and there are no guardrails. There are many obstacles underfoot, such as slab steel bars, slab formwork, construction tools, cables, wires, blocks and other debris, which can easily cause people to trip and fall. In special circumstances, it is also easy to fall and cause accidents such as dizziness, heatstroke, stepping on air, touching, etc. However, during the high-altitude operation of the cap beam slab construction, there are rarely safety guardrails for edge operations. Common reasons are: the amount of slab concrete is small, the construction cost is low, the profit is small, the construction space on the top of the cap beam is small, and it is generally believed that there is no way to install guardrails; the workers are afraid of trouble Because they are not aware of the trouble and are unwilling to spend time and effort to install guardrails, workers generally believe that the shim construction may be completed by the time the guardrails are installed; because they do not know what safety protection measures to take, even if they find that there are hidden dangers of high-altitude falling safety accidents, units and departments at all levels are unable to implement rectification to eliminate the hidden dangers, resulting in the life safety of construction workers not being effectively protected and forming a habit of construction workers violating regulations; construction workers have weak safety awareness, and a common safety protection measure for shim construction is to install clamps on the blocks at both ends of the cap beam and tie steel wire as the busbar of the safety belt, but the height of the block is only 40 centimeters, which does not meet the safety requirements. Construction workers are easily tripped by the steel wire and fall, causing safety accidents.

[0003] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content
