Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a mounting bracket for a plurality of roof units placed on the girder side of a living room of a house, and is applicable to industrialized houses built using the unit construction method. Can be used for roofs.

[Background technology]

Prefabricated construction methods are known for shortening the construction period for houses on site, and among these prefabricated construction methods, unit construction methods have recently been increasingly used. This unit construction method involves manufacturing modular units in advance at a factory, transporting these units to the site by truck, etc., and then assembling them on the foundation for construction.

In industrialized housing using this unit construction method, the roof is constructed by combining a plurality of roof units on top of a living room area formed by combining a plurality of box units. The roof unit used for roof construction has a structure in which roof panels are attached via bundles to a base panel that is placed in the living room, but the specific structures are gable roofs, hipped roofs, and hipped roofs. They are different for different types of roofs, such as roofs. For roof units placed on the girder side of the living room, all roof panels slope downward toward the girder side in the case of a gable roof, and in the case of a hipped roof or hipped roof, all roof panels are sloped downward toward the girder side. Although the roof panel is inclined toward the girder side, the roof panel on the gable side (corner part) is inclined toward the girder side and the gable side.

Traditionally, these roof panels are installed in bundles;
Various roof unit mounting brackets are used depending on the type of roof.

[Problem to be solved by the invention]

However, preparing mounting fittings for units according to the type of roof, such as a gable roof or a hip-purlin roof, not only complicates the management of the fittings but also increases the manufacturing cost of the roof unit.

SUMMARY OF THE INVENTION An object of the present invention is to provide a mounting bracket for a roof unit that can reduce the manufacturing cost of the roof unit.

[Means to solve the problem]

The mounting bracket for a roof unit of an industrialized house according to the present invention includes a base panel placed on the girder side of the living room of the house, and a center of the base panel that is attached to the center side of the building via a bundle and slopes downward toward the girder side. A mounting bracket for a roof unit that is fixed to the top of a bundle of basic units having a room root panel, which has an inclined surface that slopes toward the girder side and the girder side. The center side is the first attachment part to which the central roof panel is attached, and the gable side of the slope inclined toward the girder side is the building center side of the first gable side roof panel having the same slope as the central roof panel. The second mounting part to be attached is the girder side and the gable side sloped surface of the girder side, and the girder side and the gable side sloped surface are arranged on the gable side of the base panel and are sloped downward toward the girder side and gable side. It is characterized in that the second gable side roof panel is attached to the building center side as a third attachment part.

[Effect]

In the present invention having such a configuration, when manufacturing the basic unit from the base panel, the bundle and the central room root panel in a factory, the mounting brackets for the roof unit slanted toward the girder side and the gable side are fixed to the top of the bundle. At the same time, the central room root unit is attached to the first attachment portion formed on this attachment fitting. Additionally, first and second gable roof panels are manufactured at the factory.

At the site, a living room part of a house is formed by combining multiple box units, etc., and then a plurality of basic units are placed on top of this living room part along the girder, and a second base unit is attached to these basic units. Install the first or second roof panel and construct the roof.

For example, to construct a gable roof, a first gable roof panel with the same slope as the roof panel of this unit is attached to the gable side of the base panel of the basic unit. a second portion formed on the mounting bracket;
Attach it to the mounting part of.

In addition, in order to construct a hip-purlin roof, a second gable side roof panel is attached to the gable side of the base panel of the basic unit, which slopes downward on both the girder side and the gable side, but in this case, the center side of the building is attached to a third attachment portion formed on the attachment fitting.

Therefore, when the central room root panel and the first and second gable side roof panels are attached to the bundle, the mounting brackets are shared, so that the number of parts of the mounting brackets can be reduced.

At the same time, the roof panel 12 is attached to this unit 10, and the center room root unit 9A for the main building shown in FIG. 4 is constructed.

Furthermore, the basic unit 30 is arranged on both sides of these units 9A, and a second
The gable side roof panel 32 is attached, and the surgical room root unit 9B for the hip-purlin shown in FIG. 6 is constructed. At this time, the mounting piece 27 attached to this panel 32 is overlapped with the third mounting portion 26 of the mounting bracket, and these are connected and fixed by the connecting tool 28 in the same manner as described above.

According to this embodiment, the unit IO has the central roof panel 15 attached to the building center side of the base part 13 via the bundle 14, which slopes downward on both sides. Panel ll or panel 12 that slopes downward on the gable side is attached to form central room root units) 8A, 9A, and a central room root panel that slopes downward on one girder side via a bundle 34 on the building center side of the base part 13. The operating room root unit 8B is created by attaching a panel 31 with the same slope as the panel 35 or a panel 32 that slopes downward toward the gable side and girder side to the basic unit 30 to which the panel 35 is attached.

9B, these roof units 8A.

When constructing a gable roof or a hipped roof by combining 8B, 9A, and 9B, the unit 10.30 can be used in common, and the manufacturing cost of the roof unit can be reduced.

Moreover, when constructing operating room root units 8B and 9B,
Since the panels 31, 32, 35 are attached to one roof unit mounting bracket 20, the manufacturing cost of the roof unit can be reduced from this point as well.

In the above embodiment, the second gable side roof panel 32 forming the operating room root unit 9B is one panel board 39, but this panel 39 may be divided into two panels.

Furthermore, a gable roof or a hipped roof may be constructed by combining the roof units 8A and 8B.

Furthermore, the living room section may be constructed by a curtain wall construction method or a panel construction method, in addition to the construction by a unit construction method as in the above embodiment.
