Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention is directed to adhesive bolting of a plurality of box-shaped roof units of different types that integrate a roof panel and a shed bridge that supports the roof panel. This relates to a prefabricated hipped roof constructed of.

``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 various variations of exterior and interior designs have been developed to meet diverse needs.In particular, the shape of the roof is an important factor in determining the style of the house. Since it is an important element in the construction of buildings, 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 can enhance the individuality of the housing, it also has disadvantages such as increased reliance on on-site construction and increased number of parts, resulting in disadvantages in terms of construction time and cost. Among them, the roof, floor,
Unlike walls, it takes time and effort to assemble the roof on site, whether it's using trusses, panels, or wires such as bundles and rafters, especially when it comes to hip roofs. There was a problem in that it was necessary to consider many types of component configurations corresponding to the shape and prepare various types of parts.

Figures 19 to 22 show an example of construction of such a single-family prefabricated house.
As shown in Figure 9, 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.
Assemble the wall panels 3 on the first and second floors as shown in Figure 0 and Figure 21, and then assemble frames, wood, etc.
As shown in FIG. 22, steps are taken to assemble the roof panels 4 and construct a building.

In addition, each of the above panels (floor panel 2, wall panel 3, etc.)
The floor panel 2 is integrated with adhesive and screw nails, etc., and the floor panel 2 is laid through an architrave on the adjusted mortar adjusted to the top surface of the foundation (cloth foundation in the illustrated example) 1. The wall panel 3 is integrated with the foundation by inserting holes at the lower end of the wall panel into anchor bolts protruding from the upper surface of the concrete foundation and tightening the bolts.

On the other hand, the roof is basically assembled in the same way as any type of roof, by sequentially assembling the beams, the shed, and the roof at a high place. For example, as shown in Figures 21 and 22, If you have a gable roof like this, after constructing the roof by passing beams 5 etc. over the second floor wall panel 3, lay the roof panel 4 on top of it, and then construct the roof panel 4. Measures will be taken to integrate the

"Problems to be Solved by the Invention" The present invention aims to solve the following problems in the prior art described above.

First, conventional roof assembly involves constructing beams, sheds, and roof panels in order, making it difficult to work on-site, especially for roofs with a hipped roof shape. However, there are problems in that it takes more time and effort than a flat roof, and it also requires skilled workers, making it expensive.

Second, roof assembly work naturally involves work at a high point in a building, which is highly dangerous, and it takes a long time to assemble the roof, so items are exposed to rain during assembly. As a result, there is a problem in that it is difficult to ensure stable quality.

The present invention was proposed in view of the above circumstances, and its purpose is to safely and efficiently construct roofs at high places on buildings without requiring skilled workers. The purpose of the present invention is to provide a prefabricated hipped roof that can shorten the construction period and stabilize quality.

"Means for Solving the Problem" In order to achieve the above object, the present invention provides a hipped building having a roof surface with a downward slope in all directions, front, back, right and left, and a corner ridge where the roof surfaces meet. This is a prefabricated hipped roof in which the roof of the structure is composed of a plurality of box-shaped roof units of different types each consisting of a roof panel and a shed frame that supports the roof panel, and the roof unit has four corners of the roof. A set of four corner ridge roof units, and a set of two corner ridge roof units, which are divided into left and right sides with a large ridge running horizontally at the top of the roof as a border, and which make up the roof surface on the left and right of the large ridge. a first main roof unit, a set of two second main roof units that constitute the front and rear roof surfaces of the main ridge and are connected between the corner ridge roof units; 4 located between the main roof unit and having a corner ridge on a part of the roof surface

Furthermore, in the embodiment, each roof unit is 10, 20°, 30°.
When the 40 pieces are glued and bolted, these road walls l1i
Since the roofs 10, 20, 30, and 40 are integrated with each other and the strength of the entire roof is improved, there is also the advantage that its durability is also improved.

``Effects of the Invention'' As explained above, the present invention provides a roof with a hipped structure that has a downwardly sloping roof surface in all four directions, front, back, right and left, and a corner ridge where the roof surfaces meet. This is a prefabricated hipped roof constructed from a plurality of box-shaped roof units of different types each consisting of a panel and a shed frame that supports the roof panel, the roof unit being a roof unit with four corners forming the four corners of the roof.
a set of individual corner ridge roof units; a set of at least two first main roof units that are divided into left and right sides with a large ridge running horizontally at the top of the roof as a boundary and forming roof surfaces on the left and right sides of the large ridge; a set of two second main roof units that constitute the front and rear roof surfaces of the large ridge and are connected between the corner ridge roof units; and the corner ridge roof unit.

and a set of four third main roof units each having a corner ridge on a part of the roof surface, and each of these roof units is arranged between the roof unit and the first main roof unit. Since it is characterized by being integrated by an adhesive applied to the mating surfaces and a bolt passing through the shed frame, it has the following excellent effects.

(a) In the prefabricated hip roof according to the present invention,
There are multiple types of roof units in which the entire roof is made up of roof panels and a shed frame (corner ridge roof units in sets of 4,
Since the unit is made up of small units (first main roof unit consisting of two units, second main roof unit consisting of two units, third main roof unit consisting of four units, etc.), on-site work is easy. This is done by connecting the roof units to each other and connecting the roof units to the exterior walls.Moreover, the connection between the roof units is easily accomplished by adhesively bolting the mating surfaces of the roof units together, reducing the number of on-site man-hours. The construction period can be shortened, and since the roof units do not need to be connected to each other by climbing on the roof, safety can be improved.

(b) Furthermore, when the roof units are bonded and bolted together, these roof units are integrated with each other and the strength of the entire roof is improved.Furthermore, since the roof unit is made into a unit by the roof frame and the roof panel, There is no need for skilled workers, the workability can be improved, and the quality can be stabilized.
