Background

With the rapid development of market economy and the acceleration of urbanization, land resources are reduced, and the number of high-rise and super-high-rise buildings in cities is increased day by day. In order to ensure the construction safety, the safety protection work of the adjacent edge part in the construction process of the building engineering is also paid more attention.

At present, the safety device that limit was faced to stair mouth and stair that job site was used commonly all adopts steel pipe and all kinds of fasteners to set up the guardrail that forms, and the fixed of its pole setting generally has following two kinds of forms: firstly, the vertical rods are required to be installed from the bottom layer to the top layer in the traditional building, and small cross rods are additionally installed on the rest platform and the floor slab to prop against the wall surface to fix the vertical rods; and secondly, the bottom of the upright stanchion is additionally provided with a flange which is fixed by expansion bolts.

Of the above two methods, the first installation method is not only cumbersome to install, occupying the space of the platform and the floor slab, the process is rough, the stability is poor, when an operator operates and walks between the stairs, clothes of the operator are easy to be wound and collided to be damaged, the safety protection requirement is difficult to meet, the used steel pipes and fasteners have large and high cost, the steel pipes are protruded outwards when being erected to obstruct the passage, and the two traditional modes are used for the adjacent edge protection of the stairs, the defects of different degrees of the fixation of the protective vertical rods in two modes are found in the construction process, the commonality is mainly shown in the later stage decoration and finishing ground tile laying process, the stair edge protection needs to be removed in the ground construction process, because the stage is a blank window period for formal handrail installation, the stair edge protection is in a missing state in the ground decoration process, and serious potential safety hazards exist.

Based on this, we propose a connecting piece for the near-edge protection of stairs.
