Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial Application Field" The present invention is directed to bone bolting 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 particularly relates to a roof unit that forms the front and rear or right and left roof surfaces of the main ridge of a prefabricated 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 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 strongly individualize the housing, it also has disadvantages in terms of construction time and cost due to the increased reliance on on-site construction and the increased variety of parts. Yes, especially the roof, floor,
Unlike walls, etc., it takes time and effort to assemble the roof on site, whether it is using laths, panels, or wires such as bundles and rafters, especially for hipped roofs. However, there was a problem in that it was necessary to consider many types of component configurations corresponding to the shape of the roof and prepare various types of parts.

Figures 24 to 27 show an example of construction of such a single-family prefabricated house.
As shown in Figure 4, the unitized floor panels 2 are laid on the concrete foundation l constructed on site, and the second
Assemble the wall panels 3 on the first and second floors as shown in Figures 5 and 26, and then assemble frames, wood, etc.
As shown in FIG. 27, steps are taken to assemble the roof panels 4 and construct the 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 is laid via architraves 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, 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 Figures 26 and 27, If you have a gable roof like this, after constructing the roof frame by spanning the beams 5 etc. over the second floor wall panel 3, lay the roof panels 4 on top of this, and then construct the roof panel 4 as the roof frame. 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 order, making it difficult to work on site, especially when building a hipped roof. 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 work at a high point in the building, which is highly dangerous, and since assembly takes time, the building is exposed to rain during assembly. There was a problem in that it was difficult to ensure stable crystallinity.

Therefore, as a result of intensive research to solve these problems, the inventor of the present invention constructs a roof by a roof unit that integrates roof panels and a roof frame, and constructs a roof unit 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 a downwardly sloped roof surface on all four sides, front, back, right and left, and has a corner ridge where the roof surface and the roof surface meet. A roof unit that forms the front and rear or left and right roof surfaces of the main ridge of a roof unit for configuring a hipped roof, and includes a flat roof panel that serves as the roof surface and supports this roof panel. and a set of two triangular panels arranged opposite each other to form a mating surface with another roof unit, and an acute apex of these triangular panels. A rectangular panel is provided on the other side of the Hi material spanned between the two, and this girder material is installed on the other side to form a mating surface with another roof unit. It is characterized by being mainly composed of partition panels arranged in the.

"Function" In the roof unit for constructing a prefabricated hip roof according to the present invention, a unit is formed by the triangular panels, rectangular panels, and girder materials that constitute the shed frame, and the roof panel attached to the shed frame. Since the entire structure is box-shaped, the external force applied to the entire roof can be dispersed, improving the strength and resistance of the entire roof.

In addition, according to this construction roof unit, it is possible to form a sloped roof surface on the left and right sides or front and back of the main ridge section by simply placing girders on top of the outer wall panels, making assembly work easier on site. Since the joints between the roof units are made up of triangular panels and rectangular panels, it is possible to easily adopt a means of bonding and bolting the mating surfaces of these panels together, and furthermore, the roof units Since they collectively form the four corners of the hipped roof, there is no need to climb on the roof to connect the roof units, thereby improving safety.

In addition, since the roof unit is integrated with the roof frame and roof panels in accordance with the respective placement positions, there is no need for special techniques on site, and there is no need for skilled workers. First, it is possible to reduce costs.

In the roof units 20 and 30 of the embodiment, the entire unit is configured in a box shape by the triangular panels, rectangular panels, and girder materials that make up the shed frame, and the roof panel that is attached to the shed frame. Therefore, the external force applied to the entire unit can be dispersed, and the strength and resistance of the entire roof unit can be improved, and the joints on the roof can be completely treated using the joint material 50.
This method has the advantage of requiring less man-hours and labor on site, and furthermore, since there is no need to climb on the roof to connect the roof units, safety can be improved.

Also, each roof unit shown in the drawings l-1 0.2 0,3
When 0.40 pieces are glued and bolted together, these roof units 1 0, 2 0, 3 0.4 0 are integrated with each other and the strength of the entire roof is improved, which also improves the durability of the prefabricated hipped roof. There are also advantages to doing so.

"Effects of the Invention" As explained above, the present invention constitutes a prefabricated hipped roof that has downwardly sloping roof surfaces on all four sides, front, back, left, and right, and where the joints of the roof surfaces form corner ridges. A roof unit that constitutes the front and rear or left and right roof surfaces of the main ridge part of the roof unit, which consists of a flat roof panel that serves as the roof surface and a shed frame that supports this roof panel,
and the shed frame is spanned between a set of two triangular panels arranged opposite to each other and forming mating surfaces with other roof units, and acute apexes of these triangular panels. A rectangular panel provided on the other side of the girder material to form a mating surface with another roof unilateral, and a partition placed in parallel between the rectangular panel and the girder material. Since it is characterized by being constructed mainly from a panel, it has the following excellent effects.

(a) In the roof unit for constructing a prefabricated hip roof according to the present invention, the triangular panel, the rectangular panel, and the girder material constituting the shed frame, and the roof panel attached to the shed frame are used to form a single roof unit. Since the entire roof unit is configured in a box shape, external forces applied to the entire unit can be dispersed, and the strength and resistance of the entire roof unit can be improved.

(b) Also, according to this roof unit for construction, the front and rear or left and right roof surfaces of the hipped roof can be shaped by simply placing girders on top of the outer wall panels, making assembly work easier on site. Above, since the joining parts of the roof units are made up of triangular panels or rectangular panels, it is possible to easily adopt a method of adhesively bolting the mating surfaces of these panels to each other. Since the entire unit constitutes the four corners of the hipped roof, it is not necessary to connect the roof units to each other by climbing on the roof, thereby improving safety.

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