Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an architectural scaffolding device mainly used in the construction or repair of multi-story structures, and in particular to a pedestal unit for configuring the scaffolding device. It is.

(Prior Art) Conventional scaffolding devices used in the construction or repair of high-rise housing, etc. are constructed by combining logs with wire, or by building a unit frame made of metal pipes in the vertical and horizontal directions. It is constructed by adding and connecting.

(Problem to be solved by the invention) Therefore, in the case of high-rise housing as described above, a considerable number of days and workers are required just to erect the scaffolding or to remove the scaffolding after construction or repair of the high-rise housing. However, this caused the problem that the cost of assembling the scaffolding frame was added to the construction and repair costs, making the whole project expensive.

In view of the above points, the present invention seeks to provide a pedestal unit for manufacturing a scaffolding device that allows a scaffolding frame to be constructed and removed in a short period of time.
In other words, by simply assembling a pedestal unit in a factory or on-site, and incorporating and connecting scaffolding boards to it, it is possible to easily and easily provide a scaffolding device for construction that can be freely used vertically and horizontally, in other words, in height and horizontally. It provides a pillar unit.

(Means for Solving the Problems) The present invention has improved the above problems by providing connection brackets at the upper and lower ends of a pillar unit for a construction scaffolding device. That is, the pillar unit for the architectural scaffolding device of the present invention has two pillar units arranged in parallel at a required interval.
The book pedestal is connected with a support rod for locking the end of the scaffold board, and a joint pin is protruded from one end of both the pedestal pillars, and the joint pin is inserted into the other end. A pedestal unit for an architectural scaffolding device in which a mating hole is provided and connecting brackets are fixed to the upper and lower ends of the pedestal, respectively, wherein the upper and lower connecting brackets are perpendicular to the length direction of the support rod. It is characterized in that it protrudes and is fixed to the sides in opposite directions, and that an insertion hole for a fulcrum shaft provided in the connecting bracket is bored at an outer position from the upper and lower end surfaces of the pillar. .

(Function) According to the present invention, a building frame is formed by stacking and joining a plurality of pedestal units vertically by utilizing the engagement between the joint pins and the engagement holes of the pedestals of each unit, and By arranging any number of such building frames horizontally and using support rods to connect scaffolding boards between the building frames, it is possible to construct the structure in multiple stages vertically and horizontally. A scaffolding device can be easily constructed by connecting the scaffolding devices, and the size of the scaffolding device can be made arbitrary by selecting the number of pillar units used for each building frame and the number of building frames.

In addition, in a pedestal unit that is joined to the top and bottom, by fixing the connecting bracket of the upper pedestal and the connecting bracket of the lower pedestal with the fulcrum shaft, a joint device can be created by fitting the joint pin and the engagement hole. Since the parts can be bent using the fulcrum shaft, the entire scaffolding device can be folded in a direction that reduces the vertical thickness, and it can be easily assembled even at a construction site, and the scaffolding device can be easily stored. In addition to being easy to transport, when constructing a scaffold, the scaffolding device is hoisted and extended via the horizontal frame for regulating the spacing at the upper end using appropriate lifting equipment such as a winch, and the braces are connected while extending the pillars in a straight line up and down.
