Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a curing opening / closing dome for scaffolding installed on the top of a scaffold assembled along the outer wall of a building or other building.

[Prior Art] At work sites such as buildings that generally require work in high places, scaffolding pipe units are connected one after another along the outer wall of a building to build a scaffolding, and further material fall. To ensure the safety of workers, nets are attached to the outer periphery of the scaffold and each step. The uppermost part of the scaffold is conventionally covered by a simple method of simply covering with a sheet, a method of assembling a frame with a pipe and attaching a sheet or corrugated iron plate.

Covering the top and perimeter of the scaffold (which may be between the scaffold and the building exterior wall) not only allows for work in rainy weather, but also for rain and sunshine curing of exterior wall finishing operations. It is also important that the conventional method described above cannot sufficiently fulfill the function of the curing sheet.

Since the work of installing and removing the curing sheet is quite complicated and it is necessary to deal with sudden changes in the weather, the goal was to improve workability particularly quickly. To solve this problem, the method described in JP-A-63-167846 has been proposed.

[Problems to be Solved by the Invention] Some of the devices disclosed in the above-mentioned Japanese Patent Laid-Open Publications are fairly large-scaled systems and require a large amount of initial capital investment, and are severely damaged at a site with a long construction period. Since it tends to be disposable, it may lead to an increase in construction cost.

With a simple method of hanging the tarpaulin on the scaffold,
Not only does it often leak water, it cannot cope with strong winds at all, and it cannot be said that it can fully function as a curing sheet.

In addition, the method of assembling the pipe frame on the upper part of the scaffold and attaching the corrugated iron plate etc. is not only dangerous in the assembly work, but also
The work is complicated and it is vulnerable to strong winds. Further, since the assembly / disassembly cannot be performed easily, the function as a curing sheet is insufficient.

The present invention was created in view of the above, and in Japanese Utility Model Application Laid-Open No. 54-19863, a seat clip that is a fixture for a curing sheet is disclosed. At that time, the curing sheet is flapping, which is not only difficult, but also the removed curing sheet may be blown off by the strong wind. Further, when reattaching, it has a drawback that fixing work to a large number of attachment holes is not only complicated but also extremely dangerous since it is an operation with both hands at a high place. The purpose of this study is to reveal a curing opening / closing dome for scaffolds that can be assembled and disassembled quickly and safely, has strong wind resistance, can be opened and closed freely, and can also fully function as a curing sheet. It is what

[Embodiment] Next, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

In FIG. 1, reference numerals 1 and 2 are conventionally known pipe units for scaffolding, and the scaffolding is constructed by connecting the illustrated pipe units in horizontal and vertical directions as shown by phantom lines. The curing opening / closing dome for scaffolding (hereinafter abbreviated as dome) of the present invention is attached to the uppermost part of the scaffolding thus formed.

The dome of the present invention has a metal roof pipe 10 formed in an arc shape, and brackets 20 and 21 for fixing both ends of the roof pipe 10 to the scaffolding pipe unit 1.
And a pipe 30 attached between the brackets 20 and 21 laterally adjacent to each other and a roof sheet 40 attached to the upper part of the roof pipe 10.

In order to prevent the connection between the scaffolding pipe unit 1 and the brackets 20 and 21, and between the brackets 20 and 21 and the roof pipe 10 from being disengaged due to wind pressure, they are fixed to the connection portion by, for example, pine needle pinning 22. Of course, a mode in which bolts and nuts or other binders are used may be used.

Although it is preferable to use a flameproof sheet as the roof sheet 40, various materials such as cloth and synthetic resin can be used as long as they can withstand wind pressure and are waterproof.

A specific example of the roof sheet 40 is shown in FIG.

The roof sheet 40 has a length of about 5.7 m and a width of 3.6 m, and is configured to cover four pipe units 1 for scaffolding shown in FIG. Of course, the length of the roof sheet 40 may be longer or shorter than this, and the width is the same.

A ring 41 is provided on the back side of the roof sheet 40, as shown in FIG. The ring 41 is loosely attached to the roof pipe 10 as shown in FIG.
The roof sheet 40 is fixed to prevent the roof sheet 40 from flapping in strong winds. The spacing between the rings 41 corresponds to the spacing between the scaffolding pipe units 1 and 2 shown in FIG.

At both ends of the roof sheet 40 in the width direction, binders 42 for fixing the ends of the roof sheet 40 to the pipe 30 are provided. The binder 42 may be provided only at both ends of the position where the ring 41 is arranged, and the both ends of the roof sheet 40 may be fixed to the brackets 20 and 21.

It should be noted that it is also possible to provide eyelet-shaped small holes at appropriate intervals without providing the binder 42 as shown.

The right end of the roof sheet 40 shown in FIG. 3 is a stacking margin 43, an eyelet-shaped small hole 44 is provided at the end, and a binding member 45 provided at the right end of the roof sheet 40
Bond the overlapping parts of the continuous roof sheets.

In another embodiment of the present invention, for example, only the bracket 20 is used, and only one end of the roof pipe 10 is fixed to the scaffold pipe units 1 and 2. In such a mode, it is desirable that the open end of the roof pipe 10 is fixed to a fixing means arranged on the roof of a building or the like, as a measure against wind. Although various structures can be used as the fixing means, the simplest one is to connect the open ends of the roof pipe 10 with a pipe or the like, and connect the pipe and the heavy object installed on the rooftop. It is a method of binding with ropes or wires.

In order to eliminate the height deviation of the top of the scaffold due to the height of the building and the pipe unit built along its outer wall,
The height of the legs of the brackets 20 and 21 is preferably such that the attachment can be attached to adjust the height.

FIG. 4 shows another embodiment of the present invention.
The figure uses a pipe frame 50 in which the brackets 20 and 21 shown in FIG. 1 are integrated. Utilizing the legs 51 provided downward of the pipe frame 50,
It is attached to the upper part of the scaffolding pipe unit 1 shown in FIG.

In the embodiment shown in FIGS. B and C, it is mounted between the scaffolding pipe units 1 and 2 shown in FIG.

In the embodiment shown in FIGS. B and C, the legs for attaching to the upper portions of the scaffolding pipe units 1 and 2 are overlapped, so that, for example, the embodiment shown in FIG. It is preferable to make it continuous.

In the preferred embodiment of the present invention shown in FIG. 6, a bracket member 20A for connecting to the top 1A of the scaffolding pipe unit 1 is integrally fixed to one end of the roof pipe 10A. .

In this preferred embodiment, the other end of the roof pipe 10A is fixed to the other top 1B of the scaffolding pipe unit 1 by a bracket member 21A, or to a structure installed on the roof of a building or the like.

The open side of the roof pipe 10A having no bracket member 20A may be extended or connected to an auxiliary pipe so as to be grounded to the rooftop floor of the building.

As a measure against snowfall, it is preferable to attach a reinforcing pipe, a rope, or the like to the top of the roof pipe 10 to prevent the roof sheet 40 from hanging between the adjacent roof pipes 10 and causing snowfall.

When the wind is strong or you want to dry the outer wall, you can untie the binder 42 at one end from the pipe 30 and pull the ring 41 along the roof pipe 10 to remove the roof sheet 40.
Can be bundled on one side. In order to make this work easier, a string or the like is attached to the end portion of the roof sheet 40 in the width direction, and the roof sheet 40 is pulled from the upper side to the other end.

[Effects of the Invention] The opening / closing mechanism of the present invention does not involve any danger in installation work and is easy to open and close as compared with the conventional method, and the dome-shaped appearance is similar to that of a work site. It is also effective for up, and it is possible to achieve the purpose mentioned above.

In particular, according to the present invention, since the roof sheet is attached to one side along the roof pipe, the roof can be easily and safely opened with one hand without fluttering or being blown off even in strong wind. Since it is possible to perform the closing work again with one hand, it is easy and safe.
