Description

[Detailed description of the invention] (Industrial application field) This invention relates to a suspended scaffolding mainly used in the construction of wooden houses such as ordinary houses.

(Prior Art) Conventionally, this type of scaffolding has employed a method in which building frames of the same shape are assembled from the ground one level at a time.

(Problem that the invention aims to solve) However, since the ground has not yet been leveled, there are various constraints related to the flatness of the ground, the strength of the ground, etc. In addition, it is necessary to first level the ground or use a jack base to adjust the level before assembling the building frame, and in addition, the final leveling work and concrete work that needs to be done. In addition, the frame was bulky and difficult to transport and store.

Therefore, this idea was devised to solve the above-mentioned problems, and it is possible to connect walls to prevent falls without being constrained by the flatness of the ground or the strength of the ground. In addition to eliminating the need for level adjustment, etc., the final leveling work and dog run concrete work can be performed with or without scaffolding, and the level of the scaffolding board can be ensured. This provides a suspended scaffold that can be extremely easily transported and stored.

(Means for Solving the Problems) In order to achieve the above-mentioned purpose, this invention is designed to attach a bracket to the upper end of the support column and a bracket protruding from the rear side of the upper end of each eave of a general house. The uppermost fixed frame has hanging screws protruding from it, and the intermediate and lowermost movable frames each have a retaining ring near the top end of each column whose diameter is successively smaller than that of the fixed frame's column. After sequentially inserting the retaining ring side of each lower small diameter support from below into the upper large diameter support of this fixed frame and each movable frame, the lower end of the upper large diameter support is drawn. A suitable number of frames are constructed, which are connected one after another so as to be able to expand and contract downwards, and scaffolding boards are erected between the fixed frames of each frame and between the movable frames except for the lowest movable frame. , an abutting plate that abuts against the foundation concrete is provided protruding from the rear side of the lower end of the support of the lowest movable frame of each frame.
