Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention is directed to bonding and bolting together a plurality of box-shaped roof units of different types that integrate a roof panel and a shed frame that supports the roof panel. The present invention relates to a prefabricated hip roof constructed by a sectional roof, and in particular to a roof uninote that constitutes the four corners of a sectional hip roof.

``Conventional technology'' In single-family prefabricated houses, etc., instead of already uniform and standardized housing, for example, ``free style''
Planned prefabricated houses called ``houses'' have been supplied, and along with this, various types of exterior and interior designs have been developed to suit various needs.In particular, the roof shape is Since it is an important element in determining the style, various types of roofs are currently available, including flat roofs, gable roofs, gambrel roofs, hipped roofs, and square roofs.

By the way, while this kind of planned housing allows for strong individuality of the housing, it also has disadvantages such as disadvantages in terms of construction period and cost due to increased dependence on on-site construction and an increase in the variety of parts. Yes, especially the roof, floor,
Unlike walls, etc., it takes time and effort to create a shed on site, whether it's using trusses, panels, or wires such as bundles and rafters, especially for hipped roofs. There was a problem in that it was necessary to consider several types of component structures corresponding to the roof shape and prepare various types of components.

Figures 21 to 24 show an example of construction of such a single-family prefabricated house.
As shown in Figure 1, a unitized floor panel 2 is laid on a concrete foundation 1 constructed on site, and a second floor panel is placed on top of it.
As shown in Figures 2 and 23, the wall panels 3 on the first and second floors are assembled, and then framed, timbered, etc.
As shown in FIG. 24, steps are taken to assemble the roof panels 4 and construct the building.

Nao, each of the above panels (floor panel 2, wall panel 3, etc.) is
The floor panel 2 is integrated with cemented material and screw nails, etc., and the floor panel 2 is laid via architraves on the adjusted mortar adjusted to the top surface of the foundation (fabric foundation in the illustrated example). The wall panel 3 is integrated with the foundation by inserting a hole at the lower end of the wall panel into an anchor bolt protruding from the upper surface of the concrete foundation and tightening the bolt.

On the other hand, the roof assembly is basically the same as any type of roof, in which the beams, the shed, and the roof are assembled in order at a high place. For example, as shown in Fig. 23 and Fig. 24, If the roof is a gable roof like this, the roof panel 4 is laid on top of the roof panel by laying the beams 5 etc. over the second floor wall panel 3, and then the roof panel 4 is used as the roof panel. Measures will be taken to integrate.

``Problem to be solved by the invention'' However, conventional roof assembly involves constructing beams, sheds, and roof panels in sequence, which makes work on site difficult, especially when building hipped roofs. A roof-like structure requires more labor than a flat roof, and requires skilled workers, resulting in high costs. In particular, the work of assembling the roof naturally involves working at a high point in the building, making it highly dangerous to live in. Also, as it takes time to assemble, the building is exposed to rain during assembly. However, there were problems in that it was difficult to ensure stable quality.

Therefore, as a result of intensive research to solve these problems, the inventor of the present invention constructed a roof by a roof unit that integrates a roof panel and a roof frame, and constructed the roof by combining these roof units. The idea was that this would make on-site work easier, shorten the construction period, and improve quality.

However, at present, such an effective and suitable roof has not been developed, and there has been a particular desire to develop a roof unit for construction that constitutes a roof.

The present invention has been proposed in view of the above circumstances, and its purpose is to provide an effective and suitable roof unit for constructing a prefabricated hipped roof.

``Means for Solving the Problems'' In order to achieve the above object, the present invention provides a prefabricated type roof that has downwardly sloped roof surfaces in all four directions, front, rear, left and right, and has corner ridges at the joints of the roof surfaces.

In addition, the shed frame includes a set of two triangular panels that form a mating surface with another roof unit, and a set of three triangular panels.
It is characterized by mainly consisting of a girder extending along the outer wall at the tip of a square panel.

"Function" In the roof uni-noto for constructing a built-in type hipped roof according to the present invention, the whole uni-noto is shaped into a box shape by the triangular panels and girder materials that make up the shed frame and the roof panel attached to the shed frame. Because of this structure, the external force applied to the entire roof unit can be dispersed, and the strength and durability of the entire roof unit can be improved.

In addition, according to this roof unit for construction, the four corners of the roof can be formed by simply placing girders on top of the outer wall panels, making assembly work easier on site. Since it is made up of square panels, it is easy to employ methods of adhesively bolting the mating surfaces of the triangular panels together, and furthermore, the entire roof unit can form the four corners of a hipped roof. Therefore, there is no need to climb on the roof to connect the roof units, thereby improving safety.

The roof panel is composed of a roof panel having a ridge, and a shed frame that supports the roof panel, and the roof panel includes first and second panel parts each having a triangular shape forming a roof surface, and these two panel parts. It mainly consists of a corner ridge connecting material that connects two panel parts and constitutes the ridge of the roof panel, and
The shed frame is mainly composed of a set of two triangular panels that form a mating surface with other roof units, and a girder that spans the tips of these triangular panels along the outer wall. Because it is characterized by the following characteristics, it has the following excellent effects.

(a) In the roof unisoto for constructing a prefabricated hip roof according to the present invention, the entire unit is constructed in a box shape by the triangular panels and girder materials that make up the shed frame, and the roof panel attached to the shed frame. Therefore, the external force applied to the entire unit can be dispersed, and the strength and durability of the entire roof unit can be improved.

(b) Furthermore, according to this roof unit for construction, the four corners of the roof can be formed simply by placing girder materials on top of the outer wall panels, making assembly work easier on site and making it easier to fit roof units together. Since the section is composed of triangular panels, it is easy to use a means of adhesively bolting the mating surfaces of the triangular panels to each other, and furthermore, the entire roof unit forms the four corners of the hipped roof. Therefore, it is not necessary to perform the operation of connecting the roof units together by riding on the roof, and the safety can be improved.

(c) Furthermore, the above provides an effective and suitable roof unit for constructing a prefabricated hipped roof.
