[0002] During the construction of the stair opening before the stairs are installed, in order to ensure the construction safety of the workers and provide a construction platform for the construction workers, it is usually necessary to install a scaffold at the stair opening construction site and install the safety net on the scaffold by ropes to form a guardrail structure for protecting the stair opening, so as to ensure that the workers can get adequate protection and support when they are active near the stair opening to avoid accidents.
[0003] When installing the safety net of the existing stair opening guardrail structure, the scaffolding is generally installed first, and the ropes are fixed on the scaffolding, and the ropes are passed through the holes reserved in the safety net in sequence, and then the ropes are used to tie the guardrail to the scaffolding at the stair opening, so that the stair opening guardrail is connected to the scaffolding to form a guardrail structure for protecting the stair opening. Although the above method is relatively simple in the construction process, it still has the following defects when used:
[0004] 1. When installing the above-mentioned protective net, it is necessary to pass the rope through the holes reserved on the safety net in turn, and then use the rope to tie the protective net to the scaffolding at the stair opening to achieve the connection between the stair opening protective net and the scaffolding. This method makes the installation of the safety net too inconvenient, thereby reducing the convenience of using the guardrail structure;
[0005] 2.
