Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is to move from an external scaffold to a building veranda or the like over a handrail wall of a balcony or balcony, a waist wall such as a waist window, or the like during construction work of the building.
Conversely, it relates to a balcony scaffold for moving from a balcony or the like to an external scaffold.

[0002]

2. Description of the Related Art As a conventional balcony scaffold of this type,
A so-called stepladder structure with ladders provided on both sides of the step board is used.The lower end of one ladder is installed on the external scaffold, and the lower end of the other ladder is installed on the veranda slab surface, and the above handrail walls are installed. It was set to straddle.

[0003]

However, in the above conventional veranda scaffolding, since the lower end of the ladder is installed on the surface of the veranda slab, the lower end of the ladder becomes an obstacle during the finishing work of the slab, and the entire veranda scaffolding. Not only was it necessary to relocate, but there was a problem that the installation was unstable and dangerous. There was also a risk of hitting the veranda slab on the upper floor when heading over the balcony.

The present invention has been made in order to solve the above-mentioned conventional problems, and its object is to set a stable and reliable or simple one without fear of interfering with finishing work such as a veranda slab. It is to provide a balcony scaffolding that can be folded and compactly transported and stored. In addition, a veranda scaffold that can be safely used can be provided by crossing the tread and crossing the balcony.

[0005]

A veranda scaffold of the present invention includes a main pillar that is connected substantially in parallel, a main body frame that includes a mounting means that attaches the main pillar to an external scaffold, and a main frame that is attached to an upper end portion of the main pillar. It is characterized in that it is composed of a vertical member that is movably pivotally mounted, and a suspension ladder that is attached to the vertical member and that is composed of several steps of a rod. Also, a main pillar connected substantially parallel to each other, a main body frame including attachment means for attaching the main pillar to an external scaffold, a handrail rod attached substantially orthogonal to an upper end portion of the main pillar, and a handrail rod attached to the handrail rod. It is characterized in that it is composed of a vertical member that is movably pivotally mounted, and a suspension ladder that is attached to the vertical member and that is composed of several steps of a rod. A tread is attached between the body frame and the suspension ladder. The tread may be removably attached. Further, a protruding rod is pivotally attached to the lower end of the suspension ladder so as to be rotatable.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. In FIGS. 1 and 2, reference numeral 1 denotes a main body frame, which includes two main pillars 1a and a connecting rod 1b for connecting these main pillars 1a substantially in parallel with each other.
And a hook 1c attached to an intermediate portion and a lower end portion of the main pillar 1a. The hook 1c is hooked on a lateral support member G1 which is horizontally assembled to the external scaffold G, so that the main body frame 1 is attached to the external scaffold G. A handrail rod 2 is attached to the upper end of the main pillar 1a substantially orthogonally.

Reference numeral 3 denotes a suspension ladder, which is composed of two substantially parallel vertical members 3a and several steps (three steps in this embodiment) of the rods 3b mounted between the vertical members 3a. There is. The upper end of the vertical member 3a is rotatably attached to the handrail rod 2 by a pin 2a. In addition, the handrail rod 2 is omitted,
It is also possible to directly pivot the vertical member 3a to the upper end of the main pillar 1a.

Reference numeral 4 denotes a tread plate which is detachably attached to the guide rod 4a. One end of the guide rod 4a is pivotally attached to the vertical rod 3a by a pin 4b, and the other end of the guide rod 4a is slidably attached to the main column 1a. More specifically, a pin 4c planted at the end of the guide rod 4a is inserted into the groove 5a of the groove rod 5 provided along the inside of the main pillar 1a, and is vertically moved along the groove 5a. Slidably attached to. Therefore, the suspension ladder 3 is foldably assembled as shown by the phantom line in FIG. As shown in FIG. 3, the groove rod 5 is omitted,
A groove a'may be formed inside the main pillar 1a, and the pin 4b may be directly inserted into the groove a '. Also, the uppermost connecting rod 1b
The pin 4b or the mounting portion thereof may be provided on the above so as to have a stopper function for the sliding of the guide rod 4a.

A projecting rod 6 is attached to the lower end of the vertical member 3a of the suspension ladder 3. The strut rod 6 is rotatably pivoted in the direction of the arrow, and is adjustable so that it can be expanded and contracted to an appropriate length and can be fixed during use. An abutting plate 6a is provided at the tip of the projecting rod 6.
Is attached to the suspension ladder 3 by contacting the balcony B.
Keeps stable.

FIG. 4 shows a set state of the balcony scaffold of the present invention when the positional relationship of the cloth frame with floor G2 of the external scaffold G with respect to the veranda B is different. In each case, the footboard 4 of the balcony scaffold 4 is shown. And cloth frame G2 with floor for external scaffold G
In particular, in the case of (C), with the footboard 4 removed, it straddles the wall of the veranda B, and from the foothold 3b of the veranda scaffolding to the external scaffold G. There is no fear of hitting the head on the veranda slab B ′ on the upper floor by using the floor-mounted cloth frame G2 directly. Even in this case (C), the tread plate 4 may be directly straddled without removing it.

In FIG. 5, the balcony scaffold is folded to
By showing the stacked state, the handrail rods 2 are used for sequentially stacking, and the thrust rods 6 are used for sequentially stacking, so that the veranda scaffolds can be stacked in an orderly manner while being kept substantially horizontal. .

6 and 7 show another embodiment, in which a handrail 3a 'is attached to the vertical member 3a of the suspension ladder 3 and an auxiliary handrail 1a' is provided outside the main pillar 1a. There is. The auxiliary handrail 1a 'is fixed to the vertical support member G3 of the external scaffold G.

[0013]

EFFECTS OF THE INVENTION There is no fear of hindering the finishing work of a veranda slab, etc., and it is possible to set it stably and surely, or to fold it easily for compact transportation and storage. Also, since the treads are removable, there is no risk of your head hitting the upper slab of the veranda when you cross the balcony.
