Description

Description: TECHNICAL FIELD The present invention relates to a roof unit for a unit type prefabricated roof.

[Conventional technology]

In recent years, construction of unit-assembled houses has been increasing in order to achieve quality control and cost reduction by factory production.

Each of these residential units is generally a cubic shape, and in order to make transportation and construction efficient, so-called flat roof type in which the upper surface of the unit is directly used as a roof surface has been widely adopted.

However, since this type of roof alone lacks variations in appearance and design, for example, Japanese Patent Laid-Open No. 60-2422
Japanese Patent Publication No. 38 and the like propose a roof unit having a plurality of sloped roof surfaces.

[Problems to be Solved by the Invention]

However, in the conventional roof unit as described above, one roof unit corresponds to one resident unit, so when further floor plan of the house, change in external appearance or high quality is required. We responded to the change by creating a new roof unit with a different design each time.

However, in the above countermeasures, the types of units and various constituent members increase each time, which causes problems in production cost and management.

For example, as shown in FIG. 5 as an example, when a standard dormitory type roof unit A as shown in FIG. A roof slope surface indicated by B ₀ may be added to one end portion to request a roof unit C having a design as shown in (b). In this case, separately from the existing roof unit A as a base, by combining a new panel Ca and a new truss Cb from the beginning as shown in (c),
Since the roof unit C of the new type was manufactured, it required an extremely large number of man-hours and caused the above-mentioned problems.

The present invention has been made in view of the problems of the conventional example as described above. For example, in a standard roof unit having at least three roof slope surfaces in a ridged shape, the minimum number of new members should be added. Thus, it is an object of the present invention to provide a roof part having a new shape without increasing the load of assembling man-hours, and to provide a sub-part adding means that can easily expand variations such as a ridge shape.

[Means for solving the problem]

For this reason, in the present invention, one vertical surface configured to be factory-installed at the adjacent ends of each of the slope surfaces of a roof unit having at least three roof slope surfaces to increase or decrease the total number of roof slope surfaces. By preparing a tetrahedral assembly (sub-part) having two roof slope surfaces and a bottom surface, the above object is achieved.

[Action]

By appropriately combining the above sub-parts with the existing roof unit, it is possible to manufacture a new shape roof unit with a different number of roof slopes at a factory at low cost, so it is easy to construct a ridge shape. It is possible to expand variations such as.

〔Example〕

 Hereinafter, the present invention will be described based on examples.

FIG. 1 is an explanatory schematic diagram of an embodiment of a means for constructing a novel shaped roof unit by sub-parts according to the present invention, and FIG.

In FIG. 1, A is an example of an existing standard dormitory type roof unit, B is a sub-part of the present embodiment, and a sub-part B is added to the current roof unit A to simplify the construction. It is shown that the roof unit C having the novel shape shown in FIG. 5 (b) can be manufactured. The roof unit A and the sub parts B are manufactured at the factory.

(Structure) As shown in FIG. 2, Sazu Parts B is composed of a tetrahedron having one vertical surface 1 and two roof slope surfaces 2 and 3, and is manufactured at a factory. Production of roof unit A and roof unit A
The sub-part B will be installed at the factory. This attachment is configured to be performed by using a beam member, a structural member such as a wood beam, nails, an adhesive agent and the like, which are not shown.

(Application Example) FIG. 3 (a) to ~ (d), a new roof unit C ₁ is added to existing 4 format roof unit _{A 1, A 2, A 3} , respectively A ₄ subparts B, The respective explanatory plan views of the four cases for obtaining C ₂ , C ₃ , and C ₄ are shown in FIGS. 4A to 4C, and the newly obtained roof units C _{1 to} C ₄ and other existing ones are shown. Each of the new dormitory type roof units obtained by combining with each roof unit A _{1 to} A ₁₁ of 4 steps, 3 steps; 4 steps, 3 steps; 4 steps, 2 steps A top view is shown. As shown in the figure, by combining roof units, it is possible to construct a roof with a complicated shape in which the sloped roof surface matches the ridge.

In this way, a complex roof shape can be configured with a small number of roof unit parts, corresponding to the roof shape that changes depending on the shape of the house.

(Other Embodiments) The above embodiment has been described with respect to an example in which a sub-part composed of a tetrahedron is added to a roof-type roof unit having at least three roof slope surfaces, but the principle of the present invention is not limited to this. Of course, without limitation, it can be applied to other variants.

〔The invention's effect〕

As described above, according to the present invention, a roof unit of a new shape in which the number of roof slopes is changed can be manufactured at low cost in a factory by appropriately combining sub-parts with an existing roof unit. , It is now possible to easily expand variations such as the shape of the dormitory.
