Description

Technical field

[0001] The present utility model relates to the field of staircase construction and in particular to a construction platform for a staircase. State of the art

[0002] When constructing a house, a multi-story building must be equipped with a staircase. After the staircase is installed, if construction is to take place in the stairwell, a scaffold made of steel pipes or non-standard materials must be erected to serve as a construction platform.

[0003] However, the scaffolding must be erected on the stairs and can easily collapse during construction, offering only limited operational safety. Furthermore, the scaffolding is bulky and heavy, and each level must be repeatedly erected, making it difficult to handle and impacting construction efficiency. Many scaffolding materials are uneconomical. Disadvantages include the need for numerous stair scaffolding construction methods, time-consuming installation, significant material waste, and inadequate safety protection.

The lower end of the support frame abuts the staircase, and the upper end is connected to the support plate, so that the support frame provides good support for the support plate to improve the load-bearing capacity of the support plate and further ensure the safety of the operating personnel. When the platform is in use, the operator steps onto the support plate to carry out the construction work in the stairwell.

[0007] Preferably, the support frame comprises a vertical support, a first diagonal support, and a second diagonal support; wherein the underside of the vertical support rests against the staircase and its upper side is connected to the support plate; wherein one end of the first diagonal support is connected to the vertical support and its other end is connected to the support plate; wherein one end of the second diagonal support is connected to the vertical support and its other end is connected to the support plate; and wherein the first diagonal support and the second diagonal support are each arranged on both sides of the vertical support.
