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 it is configured to attach the tread to the external foot, there is a problem that the attachment position is restricted, and since the lower end of the ladder is installed on the veranda slab surface, There were some 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 sufficient passage space, and to provide a veranda slab. It is to provide a balcony scaffolding that does not interfere with the finishing work.

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a pair of body frames, which are mounted on the top end face of a building wall body in a direction traversing the top wall and are fixed in parallel to each other with a space therebetween. Brackets 2 and 3 for attaching a suspension ladder are vertically provided below both ends of the main body frame 1. One of the brackets 2 is fixed to the body frame 1 by welding, bolts or nuts. 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 body frame 1 by the insertion pin 3a.
It is attached to the main frame 1 and is selectively attached to a plurality of pin holes 1a formed in the main body frame 1 at appropriate intervals so that the distance to the bracket 2 can be adjusted. A pressing piece 3 is provided inside the middle part of the bracket 3.
b is attached.

Reference numeral 5 is a suspension ladder composed of two parallel vertical members 5a and several steps of foot members 5b, and a latch 5c is provided at the upper end of each vertical member 5a. The suspension ladder 5 is attached to the body frame 1 by hooking the latch 5c on the hooking pins 2a or 3c of the bracket 2 or 3. 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 veranda scaffold of this embodiment is constructed as described above, to set this on the veranda of a 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. Next, the suspension ladders 5 are retained on both sides of the body frame 1, that is, the retaining pins 2a and 3c of the brackets 2 on the inner side and the outer side brackets 3 of the handrail wall b1 by handrails 6 of the suspension ladders 5, respectively. The suspension ladder 5 is supported by being brought into contact with the wall b1 in an inclined state. 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 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, as long as 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 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 protrusion 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 is a main frame
It may be integrally fixed to 1.

[0015]

1) A pair of body frames are placed on the top end face of a building wall in a direction traversing the top face, and
Since they are fixed in parallel with each other with a space between them, the worker can cross over the top end surface of the building wall and cross it, and as a result, a sufficient passage space with the slab such as the upper veranda slab is secured. Therefore, there is no risk of the head hitting the lower surface of the slab of the upper building wall, the head can be easily moved, and work can be performed safely and efficiently. 2) Since the lower end of the suspension ladder is attached in a state where it is separated from the slab surface such as a veranda slab, there is no risk of hindering the finishing work of the slab. 3) Assembling and disassembling allows 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 frame, and the application range , Very wide range of use.
