Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a hanging scaffold that is convenient for painting handrails on balconies in apartment complexes.

[Conventional technology and its problems]

Painting of such handrails can be done easily and safely on the inside balcony side, but on the outside it is a dangerous job with the risk of falling. Therefore, scaffolding is required, but conventionally, most of the scaffolds are framed scaffolds that are erected on the ground from the outside of the building frame, and it takes time and labor to assemble and dismantle the scaffolding, resulting in high costs. Furthermore, such fixed scaffolding cannot be installed in high-rise areas or in cases where buildings are adjacent and sufficient space cannot be secured.

On the other hand, there are hanger-type suspended scaffolds used for building steel construction, etc., and some of these can be folded and stored compactly, but all of these are short in horizontal length, making it difficult to move horizontally. Not suitable for painting handrails.

The purpose of the present invention is to eliminate the disadvantages of the conventional example,
To provide a hanging scaffold which is easy to transport and set up because it can be divided and folded, and which can be formed into a horizontally elongated structure along a handrail.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention consists of a front column, a longer rear column, horizontal timbers connecting these, and a left and right support frame with mounting hardware attached to the upper end of the rear column. The lower end of the front strut, which is approximately the same height as the front strut, and the lower end of the rear strut, which is shorter than the front strut, are connected by a horizontal timber, and a central support frame is provided with mounting hardware at the upper end of the rear strut, and these left and right supports. It consists of a handrail and a scaffolding board that connect the frame and the central support frame, and removable locking parts are provided for the ends of the handrail and the scaffolding board on the sides of the front column and the side timbers of the central support frame. , the handrail and scaffolding board have one end pivoted to the left and right support frames, and the handrail has a bending part in the middle by pivoting so that it can be bent in the vertical direction perpendicular to the length direction, and the handrail and scaffolding A hook-shaped hook is provided at the other end of the plate to be hooked to the locking portion,
Furthermore, the main feature of the scaffolding board is to have an intermediate support that is rotatably erected, and has a recess that allows the middle of the handrail to be removably received.

[Effect]

According to the present invention, it is possible to form a scaffold with a large lateral movement space by using horizontally long handrails and scaffolding boards, and the handrails and scaffolding boards themselves are folded laterally at the center and tightly attached to one support frame. arranged as
Can be stored as a compact panel body.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

Fig. 1 is a side view showing an embodiment of the suspended scaffold of the present invention, Fig. 2 is a front view of the same partially omitted, and Fig. 3 is a view taken along the line A-A in Fig. 2; 1′
indicates the left and right support frames.

The left and right support frame 1 includes a front support 1a, a longer rear support 1b, and a horizontal timber 1c connecting these.
1c'..., and mounting hardware 2 is attached to the rear column 1b.
is provided so as to protrude rearward. There are various possible configurations for this mounting hardware 2 as long as it utilizes the tightening force of a screw, but one example is an L-shaped angle member 2a that is rotatably joined at one end and is provided with a fixing bolt 2b. It was designed to be hung on the upper end of the waist wall 3.

On the other hand, the central support frame 1' is placed in the center of the scaffold in parallel with the support frame 1, and is provided with mounting hardware 2' that is the same as the mounting hardware 2 of the left and right support frames 1, and has a short rear support as a whole. 1b', a front strut 1a' having approximately the same height as the front strut 1a, and these struts 1
It consists of a horizontal timber 1d that connects a' and 1b' at their lower ends. Among these, the horizontal timber 1d was made of a large diameter with some vertical width.

In the left and right, upper and lower two stages of the front column 1a' of the support frame 1',
In addition, there are handrails 8, which will be described later, on the left and right sides of the horizontal timber 1d, and on the front and back.
8' and the locking parts 6 and 7 at the ends of the scaffolding board 9 are formed.

The handrails 8, 8' and the scaffolding board 9 are pivoted at one end to the support frame 1, and the handrails 8, 8' have a bent part 8a in the middle by pivoting, and the handrails 8, 8' and the scaffolding board 9 At the other end, hooks 8b and 9b which are hooked onto the locking portions 6 and 7 are provided. the locking part 6,
7 is a box body having a recess into which the hooks 8b and 9b are inserted from above.

Further, an intermediate support 10 is rotatably raised on the scaffold board 9, and a hook-shaped recess 10a is provided in the middle thereof to receive the central lower surface of the handrail 8', and a recess 10b is provided at the upper end to receive the central lower end of the handrail 8. Formed. 9a in the figure shows the pivot support to the scaffolding board.

Although FIG. 2 shows only half of the suspended scaffold of the present invention, there is also a support frame 1 on the left side of the support frame 1', and handrails 8, 8' and scaffolding boards 9 are stretched between them. shall be taken as a thing. Furthermore, if extruded aluminum members are used as the members constituting the scaffold, it will be lightweight and have good physical condition.

Next, to explain how to use it, in order to install the scaffold, as mentioned above, attach the mounting bracket 2 of the support frame 1 to the upper end of the waist wall 3, and attach the attachment bracket 2' of the support frame 1' to the rising part 5a of the balcony 5. Fix each. In this way, a scaffold is assembled by attaching the support frames 1, 1' and extending the handrails 8, 8' and the scaffolding board 9 between them, but these handrails 8, 8' and the scaffolding board 9 do not bend downward. It is safe for people to ride on.

On the other hand, when not in use, the handrail 8,
8' and the other end of the scaffold board 9, bend the handrails 8, 8' into a chevron shape from the bent part 8a as shown in Fig. 4,
The intermediate support 14 is also brought down and brought close to the scaffolding board 9, and the scaffolding board 9 is pulled upward. If you do this,
The entire structure is folded up, and as shown in FIG. 5, it is arranged in a panel shape so as to be in close contact with the support frame 1.

[Effect of idea]

As described above, the suspended scaffold of the present invention is horizontally elongated as a whole to ensure sufficient movement space, and can be folded horizontally rather than front and back. Therefore, it is compact when stored and transported,
It is easy to use and can be transported by a single person, carried through a narrow residential entrance, and easily assembled on a narrow balcony.
