Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a balcony scaffold for straddling a handrail wall of a veranda or a balcony, a waist wall of a waist window, or the like during construction of a building.

[0002]

2. Description of the Related Art As a conventional balcony scaffold of this type,
There is a structure in which a tread plate is arranged above a handrail wall of a veranda, the tread plate is attached to an external scaffold, and a ladder is provided between the tread plate and the veranda slab.

[0003]

However, in the above-mentioned conventional balcony scaffold, since the tread plate is arranged above the handrail wall, the space between the balcony scaffold on the upper floor is narrowed and it is difficult to secure a space as a passage. In addition to the above, since the tread plate is configured to be attached to the external scaffold, there is a problem that the attachment position is restricted, and because the lower end of the ladder is installed on the veranda slab surface, There were also problems such as hindering the finishing work of the slab.

The present invention has been made in order to solve the above-mentioned conventional problems, and its purpose is to make setting easy and reliable, to ensure a sufficient passage space, and to provide a veranda slab or the like. To provide a balcony scaffolding that does not interfere with the finishing work of

[0005]

The veranda scaffold of the present invention comprises a pair of main body frames fixed substantially parallel to the top end surface of a building wall such as a handrail wall or a waist wall, and at least the building of the main body frame. The suspension ladder is attached to the end on the side in a suspended state. Brackets are vertically provided from both ends of the main body frame, and means for tightening and fixing the building wall body to these brackets is provided. Attach the suspension ladder to the lower end of the bracket. Attach the suspension ladder detachably. A handrail is detachably or integrally attached to the body frame. At least one bracket is configured to be movable along the body frame. A projecting member is provided inside the lower end portion of the suspension ladder to support the suspension ladder in an inclined state.

The attachment of the balcony scaffold of the present invention is not limited to the handrail wall of the veranda, but may be a handrail wall of a balcony, a waist wall of a waist window, or a steel beam.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a main body frame, and brackets 2 and 3 for attaching a suspension ladder are vertically provided below the both ends of the main body frame. One of the brackets 2 is fixed to the body frame 1 by welding, bolts, nuts or the like. The bracket 2 is provided with a screw jack type fixing member 4 inwardly in the middle part thereof. The other bracket 3 is detachably attached to the main body frame 1 by the insertion pin 3a.
By selectively attaching to a plurality of pin holes 1a formed at appropriate intervals, the distance to the bracket 2 can be adjusted. A pressing piece 3b is attached to the inside of the middle portion of the bracket 3.

Reference numeral 5 is a suspension ladder composed of two parallel vertical members 5a and a plurality of steps 5b, and a latch 5c is provided at the upper end of each vertical member 5a. By suspending the latch 5c on the retaining pins 2a or 3c of the brackets 2 or 3, the suspension ladder 5 is attached to the main body frame 1
Attach to A tension member 6 is attached to the inside of the lower end of the vertical member 5a.

Reference numeral 7 denotes a handrail, the lower end of which is inserted into a mounting projection 8 provided on the body frame 1 to form a pin hole 8
The fixing pin 9 is inserted and fixed to a and 7a.

Since the balcony scaffold of this embodiment is constructed as described above, in order to set it on the balcony of the building, as shown in FIG.
The handrail wall b1 is placed on the top end surface of the handrail wall b1, and the handrail wall b1 is clamped and fixed by the fixing bracket 4 and the pressing piece 3b provided on the handrail wall b1. Next, the handrail 7 is attached to the body frame 1. Subsequently, the suspension ladder 5 is hooked on both sides of the main body frame 1, that is, the retaining pins 2a and 3c of the bracket 2 on the inside of the handrail wall b1 and the bracket 3 on the outside of the handrail wall b1, and the projecting member 6 of the suspension ladder 5 is attached. The suspension ladder 5 is supported in an inclined state by being brought into contact with the handrail wall b1. The lower end of the suspension ladder 5 is separated from the slab b2 of the veranda B.

According to the procedure of the above setting, as shown in phantom lines in FIG. 2, the balcony handrail T is attached to the top end of the handrail wall b1.
It can be set even when is attached. However, when the handrail T is not provided, it is not always necessary to follow the above procedure. For example, the whole handrail may be assembled in advance before setting, and then the handrail wall b1 may be set in a saddle type. Good. In the figure, E is an external scaffold, and F is a fall prevention plate.

In the above embodiment, the brackets 2 and 3 are vertically provided on the main body frame 1, and the handrail wall b is attached to the brackets 2 and 3.
Although the fixing metal fitting 4 and the pressing piece 3b as the fixing means to 1 are provided, the present invention is not limited to this, and the main body frame 1 can be fixed to the building wall body such as the handrail wall b1. Either means may be used.

In the above embodiment, the hanging ladder 5 is detachably fastened to the lower ends of the brackets 2 and 3 by the latching pins 2a and 3c and the latch 5c, but the present invention is not limited to this. Alternatively, the suspension ladder 5 may be directly attached to both ends of the main body frame 1. The suspension ladder 5 may be attached to at least the end of the main body frame 1 on the building side, and the suspension ladder 5 outside the building can be omitted. Further, at least one suspension ladder 5 may be integrally connected to the main body frame 1 without being detached.

In the above embodiment, the lower end portion of the handrail 7 is inserted into the mounting projection 8 provided on the main body frame 1 and the fixing pin 9 is inserted.
Although the present invention is not limited to this, the present invention is not limited to this.
Either configuration may be used. Further, the handrail 7 may be integrally fixed to the body frame 1.

【The invention's effect】

1) Since there is no tread on the top of the handrail (waist) wall, the passage space with the upper veranda slab and the like can be maximized. 2) Since the suspension ladder method is used, the lower end of the ladder is away from the slab surface, so it does not interfere with the slab finishing work. 3) Assembling and disassembling enables not only easy transportation and storage but also setting on a handrail wall with handrails. 4) Since it is set directly on the handrail (waist) wall such as a balcony,
Not only is it not affected by the mounting position due to the external scaffolding, but by setting this veranda scaffolding on a steel beam, for example, it is possible to move from the external scaffolding etc. over the steel beam to the skeleton. , Very wide range of use.
