Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for constructing scaffolding for roofing work on the roof of an industrialized house using a unit construction method.

[Background technology]

Manufactured housing built using the unit construction method, that is, manufactured housing in which multiple housing units are pre-produced at a factory and placed in a predetermined position at the construction site using a crane, and these housing units are assembled. It is also formed by placing a plurality of roof units pre-produced at a factory in a predetermined position at a construction site using a crane and then combining these roof units.

These industrialized houses require scaffolding for roof work to allow workers to work on the roof. Conventionally, temporary scaffolding was assembled around the house, and steel pipes were placed on top of it to match the roof slope. Scaffolding for roof work was established by combining pipes into chevrons, but the work of assembling heavy steel pipes was time-consuming and extremely dangerous.

[Problem to be solved by the invention]

For this purpose, multiple roof units are placed in a predetermined position using a crane and assembled together to form a roof, and then supports are erected on each roof unit, and roof work hands are installed between these supports. Although it is possible to erect horizontal materials that will serve as sills, this requires that the work of erecting the supports and the erection of the horizontal materials must be done on the roof before the actual roof work is done. These tasks also require work at heights.

In addition, when constructing scaffolding for roof work on the roof using pillars, horizontal materials, etc. as described above, it is not necessary to construct a large scaffold because this work will be performed at a high place. This can be difficult, and there is a limit to the size of scaffolding that can be constructed.

The purpose of the present invention is to make it possible to complete the work on the roof of an industrialized house in a short time without any danger, eliminate the need to work at heights, and make it possible to construct a large scaffold for roof work. The purpose is to provide a method for constructing scaffolding for work.

[Means to solve the problem]

The method for constructing scaffolding for roof work of an industrialized house according to the present invention is a method for constructing a scaffold for roof work of an industrialized house, in which each roof unit is hoisted by a crane and placed in a predetermined position, and a roof is formed by combining these roof units. By attaching a scaffolding unit to the roof unit before the lifting operation using the crane, placing this roof unit in a predetermined position during the lifting operation using the crane, and combining it with another roof unit, the scaffolding for the roof operation using the scaffolding unit can be installed as described above. It is characterized by being installed on the roof.

[Effect]

Attaching the scaffolding unit to the roof unit is performed either when the roof unit is made in the factory or when the roof unit is transported to the construction site and placed on the ground.

For this reason, the scaffolding unit installation work is done at a low location, which allows the scaffolding unit to be made larger.The scaffolding unit installation work is then carried out by lifting the roof unit with a crane and placing it in a predetermined position. By combining the roof unit with the roof unit, scaffolding for roof work can be created in a short time on the roof without having to work at heights.

〔Example〕

An embodiment of the present invention will be described below based on the accompanying drawings.

FIG. 1 shows a roof 1 of an industrialized house to which the construction method according to this embodiment is applied. This roof l is formed by transporting a plurality of housing units produced in advance at a factory to a construction site, hoisting these roof units in order with a crane, placing them at predetermined positions, and combining them. In this embodiment, the roof unit includes central units 2 and 3, folding units 4 to 7 arranged on both sides of these central units 2 and 3, and central units 2 and 3 and folding units 4 to 7.
It consists of eaves units 8 to 17 that are arranged side by side so as to surround the entire circumference of the tip of the roof l and form the outer end of the roof l. In this embodiment, scaffolding units 18-21 are attached to each of the folding units 4-7.

The shapes of these scaffolding units 18 to 21 and the structure of their attachment to the folding units 4 to 7 are the same, and FIGS. 2 and 3 show the scaffolding unit 18 of the folding unit 4 as a representative example.
It shows.

As shown in FIG. 3, the scaffolding unit 18 includes a horizontal portion 22 and a vertical portion 23 extending downward from the end of the horizontal portion 22 on the eaves side.
and a rising portion 24 extending vertically upward from the upper end of the vertical portion 23.
A net 25 is stretched over an opening provided in the rising portion 24. Horizontal part 22 and vertical part 23
constitute the legs of the scaffolding unit 18, and the horizontal part 2
2 can also accommodate workers who perform roof work. The rising part 24 is a protective wall to prevent workers from falling while working on the roof.

As shown in FIG. 2, mounting protrusions 26 are provided at both ends in the longitudinal direction of the horizontal portion 22 and the vertical portion 23, and bolts 27 inserted into these mounting protrusions 26 connect the folding unit as shown in FIG. The scaffolding unit 18 is attached to the folding unit 4 by being screwed into a nut 28 buried inside the folding unit 4.

The installation of the scaffolding units 18 to 21 to the folding units 4 to 7 is carried out at the factory where the folding units 4 to 7 are manufactured.
Alternatively, this is performed while the folding units 4 to 7 are placed on the ground after being transported from the factory to the construction site by truck.

After the installation of each scaffolding unit 18-21 is completed, as shown in FIG. The roof l shown in FIG. 1 is formed by combining the roof units.

In this embodiment, the scaffolding units 18 to 21 are attached to each of the folding units 4 to 7 before the crane 29 lifts the roof. Once formed, scaffolding units 18 and 19 are placed on both sides of the central unit 2.3.
Scaffolding 30 for roof work by 20 and 21 is automatically completed. Using this scaffold 30, a worker performs predetermined roof work, such as attaching roof finishing material to each roof unit, connecting joints between roof units, etc. After completing this roof work, the scaffolding units 18 to 21 are removed, and then the scaffolding units 18 to 21 are removed.
Roof work will be carried out on areas where work could not be done because 21 was installed, and roof l will be completed.

According to the present embodiment described above, the installation of the scaffolding units 18 to 21 to the folding units 4 to 7 is carried out in a factory or on the ground at a construction site, and this work is not done at a high place on the roof. Scaffolding units 18 to 2 can be used at low locations.
1 can be made larger, resulting in a roof work scaffold 3
Since the value of 0 can be increased, workers working on roofs can perform predetermined work with peace of mind.

In addition, after attaching the scaffolding units 18 to 21 to the folding units 4 to 7, if these folding units 4 to 7 are placed in a predetermined position by lifting with a crane, the scaffolding units 18 to 21 can be used for roof work. Scaffolding 30 is automatically completed on roof 1, and there is no need to perform work to build scaffolding on the roof, which is a high place, so construction of scaffolding for roof work at a construction site can be completed in a short time. I can do it,
As a result, it is possible to increase the features of industrialized housing based on the unit construction method, whose main purpose is to reduce work at the construction site and shorten the construction period.

In addition, although the scaffolding 30 for roof work of this embodiment described above had spaces between the scaffolding units 18 and 19 and between the scaffolding units 20 and 21, it is possible to arrange these scaffolding units side by side with almost no space between them. It is also possible to set In addition, the roof l of this embodiment has central units 2 and 3 and a folding unit 4.
7 and eaves units 8 to 17, the present invention can also be applied to roofs formed by combinations of other units, and can also be applied to roofs of arbitrary shapes. Further, although the work scaffold 30 of this embodiment is made of a plurality of scaffold units, it is also possible to use only one scaffold unit and use this scaffold unit to provide a roof work scaffold on the roof.

〔Effect of the invention〕

According to the present invention, when constructing scaffolding for roof work on a roof, the work can be completed in a short time without any danger, and
There is no need to work at heights, and it is possible to construct large-scale scaffolding for roof work.
