Description

TECHNICAL FIELD The present invention relates to a roof unit in which a roof panel and a base assembly supporting the roof panel are integrated, and in particular, the base assembly supporting the roof panel is roofed. The present invention relates to a climbing beam type roof unit mainly composed of a pair of left and right climbing beam main bodies extending along the slope of the climbing beam body and a shed panel coupled to the upper ends of the climbing beam body and supporting the climbing beam body. .

“Prior art” For detached prefabricated houses, for example, “freestyle” has been used instead of standardized houses.
Planned prefabricated houses called etc. are supplied, and in accordance with them, various variations of exterior and interior design are being developed to meet various needs.In particular, the roof shape determines the style of the house. Since it is an important factor, various types of roofs such as flat roofs, gable roofs, iris roofs, dormitory roofs, and square roofs are now provided.

By the way, such a planned house can strongly aim for individuality of the house, but on the other hand, there is a drawback in that it has disadvantages in terms of construction period, cost, etc. due to increased dependence on site construction and increased types of parts. Yes, among them, the roof is the floor,
Unlike walls, whether using trusses, panels, or wire rods such as bundles or rafters, it takes a lot of time to construct a shed on site, and for example, a complex roof such as a ridge roof. In the roof shape, there is a problem that various kinds of parts must be prepared in consideration of various kinds of parts configurations corresponding to the roof shape.

8 to 11 show one construction example of such a single-family pre-bab house, and in this conventional example, as shown in FIG. 8, a unitized floor is constructed on the concrete foundation 1 of the site construction. A panel 2 is laid, and a wall panel 3 on the first and second floors is laid on it as shown in FIGS. 9 and 10.
The steps of assembling the building, constructing a building by assembling the roof panel 4 as shown in FIG.

Roof assembly is basically the same for any type of roof,
Beams, sheds, and roofs are assembled in order at a high place. For example, if a gable roof as shown in Fig. 10 and Fig. 11 is used, beam members 5 etc. on the second floor wall panel 3 The roof panel 4 is laid on the roof panel 4 after the roof panel 4 is laid over it, and the roof panel 4 is integrated with the roof panel.

"Problems to be solved by the invention" However, in the conventional roof assembly, since the steps of constructing the beam, the hut, and the roof panel in order are adopted, workability at the site is poor, and in particular, the drawings Problems such as gable roofs as shown in Figure 2 and other shapes such as hipped roofs are more expensive than flat roofs and costly because skilled workers are required. There was a point.

Especially, assembling work of the roof is, of course, performed at a high place of the building, which is highly dangerous.
Since it takes a long time to assemble, the building is exposed to rain during assembly, which makes it difficult to secure stable quality.

In addition to the above-mentioned problems, the roof of the conventional technique has a problem that it is difficult to make a large storage space in the back of the shed due to the structure of the shed, and the space of the back of the shed cannot be used effectively. .

Therefore, as a result of earnest research to solve these problems, the present inventor has proposed that the roof be configured by a roof unit in which a roof panel and a roof frame are integrated, and that these roof units be constructed in combination. This led to the idea that on-site work would be easier, and that the construction period could be shortened and quality could be improved.

However, at present, such an effective and appropriate roof has not been developed, and in particular, the development of a roof unit that can effectively use the space inside the attic has been desired.

The present invention has been proposed in view of such circumstances, and an object thereof is to provide an effective and appropriate roof unit for constructing a prefabricated roof capable of maximally utilizing an attic space. To do.

[Means for Solving the Problem] In order to achieve such an object, the present invention couples a base assembly of a roof unit to a pair of left and right climbing beam bodies extending along a slope of a roof and an upper end of the climbing beam body.

The lower end of the beam main body is provided with a bracket for supporting the climbing beam main body on the upper end of the wall panel.

Further, in order to achieve the same purpose, the climbing beam main body is composed of a lower half plate-like body adapted to the roof inclination and a horizontal upper half plate-like body. And the upper half plate-shaped bodies are connected and coupled via the backing plates arranged on their side surfaces, and the roof panel is sandwiched between the ridges and the first and second panel portions located above and below the foundation assembly, It is characterized in that it is mainly composed of a corner ridge connecting material for connecting these two panel portions.

[Operation] In the climbing beam type roof unit according to claim 1, the pair of left and right climbing beam main bodies and the shed panel support the roof panel forming the roof surface, and the climbing beam main body,
Since the entire unit is assembled by the hut panel and the roof panel, the external force applied to the entire unit can be dispersed to each component member, and the strength and yield strength of the entire roof unit can be improved.

Further, the roof unit can be easily set on the wall by the receiving metal fittings provided at the lower end of the climbing beam main body and the hut panel, so that the entire roof unit can be easily lifted and installed at a predetermined place. Assembling work can be applied, and further, it is not necessary to connect the roof units to each other on the roof, and the safety can be improved.

Moreover, according to this climbing type roof unit, since the roof panel is supported by the climbing beam main body along the slope of the roof and the attic is constructed, the attic space can be utilized to the maximum extent, It becomes possible to construct a large ceiling storage inside.
