Description

[Detailed description of the invention] (Industrial application field) This invention relates to a scaffolding device for indoor and outdoor work.

(Conventional technology) Ducts, piping, heat insulation, etc. in heating equipment construction, etc.
For small-scale painting work, a stepladder or a stand of an appropriate height is used, and for relatively large-scale work, a rolling tower is generally used.

(Problem to be solved by the invention) However, when the construction work is of medium size, the stepladder, stand, etc. mentioned above cannot be used, and there are cases where a rolling tower is too large and inappropriate.

(Means for Solving the Problems) The present invention is a four-legged tower-shaped scaffold that can be assembled and disassembled at any time in order to provide an intermediate scaffolding device between the conventional stepladder type and rolling tower type. Then, a pair of ladder-like frames in which two vertical bars are connected by several horizontal bars above and below are placed facing each other, and both sides of the frames are connected by continuous bars at the top of the vertical bars of each ladder-shaped frame. Scaffolding in which a frame-shaped connecting member in which rods and short rods are connected vertically and horizontally is hooked to the lower horizontal rods of both ladder-like frames with hooks provided at both ends of each longitudinal rod, and hook pieces are protruded from both ends. The work scaffold is characterized in that the board is hung by the hook pieces to the cross bars of appropriate steps of the opposing ladder-like frames and stretched between the two ladder-like frames to form a four-legged tower shape.

(Function) The work scaffold according to the present invention has a pair of ladder-like frames 3
A scaffold board 6 is connected between the ladder frames 3 and 3 by a connecting rod 4 and a connecting frame 5, and has a hook piece 7 at each end between both ladder frames 3, 3.
is hooked to the horizontal rod 2 of each ladder-like frame 3 with the hook piece 7 to form a four-legged tower-like work scaffold, and the ladder-like frame 3, the connecting rods 4, the connecting frame 5 and the scaffold board 6 are detachable. Since they are freely connected, the mounting height of the scaffold board 6 can be set arbitrarily, and therefore, a scaffold suitable for the work site can be easily assembled or disassembled at any time.

(Example) Embodiments of the present invention will be described with reference to the drawings.

In the drawing, 3 is a ladder-like frame in which two vertical rods 1, 1 are connected by an appropriate number of horizontal rods 2 at appropriate vertical intervals, and the pair is faced to each other, and the upper portions on both sides are
A frame in which each end of two intersecting rods 4, 4 are connected to the vertical rod 1 by screwing, and two longitudinal rods 5a, 5a and an appropriate number of short rods 5b are connected vertically and horizontally. By hooking the hook portion 5c provided at the tip of each longitudinal rod 5a to the lower horizontal rod 2 of the opposing ladder-like frame 3, the two ladder-like frames 3, 3 are integrally connected, and both ends of the ladder-like frame 3 are connected together. Scaffolding board 6 with hook pieces 7 protruding from it
were hooked to the horizontal bars 2, 2 of appropriate steps of both ladder-like frames 3, 3 by the hooks 7, thereby constructing a four-legged tower-like work scaffold.

Therefore, the work scaffold can be formed by assembling the constituent members of the ladder frame 3, the connecting rods 4, the connecting frames 5, and the scaffolding boards 6 as needed, and disassembling each upper part as necessary, and binding the scaffolding boards 6 together. By selecting the horizontal beams 2 of the ladder-like frame 3, it is possible to form a sturdy scaffold with a height suitable for the site.

In the illustrated example, a mesh board is used as the scaffolding board 6 as shown in the platform 2 figure, but it is optional to use other types of scaffolding boards.

Although not shown, casters are attached to the lower ends of the vertical bars 1 of the ladder frame 3 to facilitate movement in the workplace.

As shown in FIG. 3, the four-legged tower-shaped scaffold according to the present invention has two or more of them arranged at appropriate intervals, and adjacent work scaffolds are connected to the scaffold board 6 described above. A ladder-like frame 3 of a scaffold that faces a hook piece 7 of
By latching onto the horizontal rods 2 of the scaffolding and successively connecting adjacent tower-like scaffolds with the scaffolding plates 6, a long scaffolding device convenient for work can be formed in accordance with the site.

(Effects of the invention) The work scaffold according to the invention forms a four-legged tower-like scaffold by removably connecting each member of the pair of ladder-like frames, the connecting frame, and the scaffolding board.
Its structure is robust and highly safe, and it can be easily assembled at any time, and disassembled into individual parts when not in use for easy transportation.In use, the installation height of the scaffolding board can be determined by selecting the horizontal rod that connects the scaffolding board. It has an effect that can be changed arbitrarily.
