Description

Technical Field

[0001] The utility model relates to the technical field of guardrail installation fixtures, in particular to a fixture for the guardrail of a staircase inclined section. Background Art

[0002] As is well known, during the construction of building projects, temporary edge guards are often required to be set at the edges of staircases to reduce the risk of falling. The staircase edge guardrail is a railing installed at the edge of the staircase, which is used to protect people's safety when walking on the staircase. Its main function is to prevent people from falling or slipping on the staircase, and at the same time provide support and balance.

[0003] The traditional method is to use an electric drill to drill holes and drive expansion bolts to fix the railing columns. This method will damage the structure. When removing the temporary guardrail later, the bolts need to be cut, which is time-consuming and laborious, and the safety and economy are poor. Moreover, after the existing guardrails are fixed, it is not convenient to move their positions. As a result, if there is a position deviation during installation, the installation will be very troublesome, thus increasing the installation difficulty. Content of the Utility Model
