Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof panel installation structure in a unit house or other building.

[0002]

2. Description of the Related Art Conventionally, as a roof panel installation structure of a unit house, a plurality of mountain-shaped roof trusses parallel to the gable surface are arranged in the girder direction, and roof panels are placed on these roof trusses to finish roofing materials and the like. The structure of applying wood is generally adopted. In addition to this, the roof may be divided into several triangular boxes to be manufactured in a factory, and then transported to the site to be joined to the unit roof.

[0003]

The above-mentioned unit roof type has a high factory production rate and requires a relatively small amount of on-site work. However, since a three-dimensional roof unit is to be transported to the site, it is difficult to transport. ineffective. Moreover, it is necessary to divide the roof unit into small roof units due to the size restrictions under the Road Traffic Law, which increases the number of units and the number of trucks. Because of these, transportation costs increase. Further, since the roof unit is divided into a large number in this way, the work of processing the connecting portion on the site increases. Moreover, the division of the roof unit is also performed in the end direction, and a large number of inter-unit connection portions extending in the lateral direction (column row direction) are formed on the roof surface. Compared to the vertical (direction along the roof slope) connection in the horizontal direction of the roof surface, it is more difficult to finish rain, which is a complicated and time-consuming operation. Therefore, even if the unit roof type is adopted, it is difficult to obtain the expected labor-saving effect of on-site construction, and it is disadvantageous in terms of cost etc. when comprehensively judged. It is often referred to as a form of roof.

Since the above truss type roof is composed entirely of flat parts, it is more efficient in transportation than the unit roof type. However, since all conventional roofs of truss type use roof trusses parallel to the gable surface, the roof trusses have a mountain shape or a triangular shape obtained by dividing the roof truss into two. As a result, the upper chord member of the truss becomes oblique, and since the diagonal member is welded to this, many parts are required to have various precision when manufacturing the truss in the factory, which is troublesome to manufacture. Moreover, since the truss is a mountain-shaped truss that corresponds to the entire gable, the shape of the truss becomes large, which requires a large work space in the factory production and a large stock space for the completed roof truss. . Further, even when the truck is transported from the factory to the site, the truss shape is mountain-shaped, so that space efficiency is poor. In addition, if the truss length becomes long, the height and length do not fall within the limits of the Road Traffic Law, and it is necessary to carry it as a triangular partial truss divided as described above, which is troublesome for transportation and site assembly. It takes.

An object of the present invention is to provide a roof panel installation structure in which the components can be efficiently transported and stored on site and can be easily installed on site.

[0006]

The roof panel installation structure of the present invention uses a roof frame structure consisting of vertical plane ramen or trusses extending in the girder direction, and a roof panel bracket mounted thereon. is there. As the roof frame, a ridge roof frame that is erected along the ridge on the main body of the building and an intermediate roof frame that is erected at a position away from this position in the direction of the eaves are provided. Roof panel bracket
The upper surface is an inclined surface that follows the roof slope and is attached to the upper surface of each roof frame and the upper surface of the eaves girder of the building body. The panel frame of the roof panel is placed and fixed on the roof frame and the roof panel bracket of the eaves girder.

Depending on the length from the ridge of the building to the eaves,
The middle roof frame may be omitted. The roof panel receiving member may be an assembly or the like having the following configuration, or may be an integral casting. In the case of an assembled product, the roof panel bracket on the eaves girder and the roof panel bracket on the middle roof frame have, for example, the following configurations. That is, a grooved steel section having a lateral groove shape and an upper end surface being an inclined surface, a bottom plate joined to the bottom surface of the grooved steel section, and a top plate fixed by covering the upper end of the grooved steel section. And constitute a roof panel bracket. The roof panel bracket on the ridge roof frame can be an assembly with the following configuration. That is, this roof panel support has a grooved steel section having an upward groove shape and the upper ends of both flanges are inclined in an inverted V shape, and an inverted V shape.
And a top plate having an inclined plate portion that opens in a letter shape and covering and fixing the upper ends of both flanges of the channel steel section. It is desirable to raise frame temporary receiving pieces for engaging the upper frame member of the panel frame on both side edges of each inclined plate portion of the upper plate.

[0008]

In this roof panel installation structure, since the roof frame is a vertical plane frame or truss extending in the girder direction, these roof frames are rectangular flat parts. Therefore, it can be efficiently transported and stored in the factory, and accuracy can be easily obtained when assembling in the factory, so that a wide space is not required in the assembly place. The roof panel will be installed on the eaves girder of the roof frame and the building main body in a slanted manner. On the roof frame and eaves girder, the roof panel receiving member whose upper surface is an inclined surface along the roof slope Since the panel frame of the roof panel is mounted and fixed on it, the workability is good and it can be fixed stably and firmly. The roof panel bracket can be made into a small shape by itself, making it convenient to carry. Further, if the roof panel support is attached to the roof frame on site, no protrusion is formed on the roof frame during transportation or storage, and transportation and storage are easier. Further, since the roof panel support is a separate component from the roof frame, by preparing roof panel supports with various slopes, the same type of roof frame can be used for various roof slopes. Therefore, mass productivity and material management can be improved.

When the roof panel support on the eaves girder and on the middle roof frame is an assembly of the channel steel section and the bottom plate and the upper plate as described above, the channel steel and the steel plate are low in material cost. And the roof panel bracket can be obtained at low cost. Further, the metal itself and the mounting holes of the panel frame can be easily machined, and the strength can be secured because the channel steel pieces are used. further,
Since the hands and tools are inserted inside the open surface of the channel steel, it is easy to install with bolts.

When the roof panel support fitting of the ridge is composed of the channel steel section and the top plate as described above, this can also be manufactured at low cost and with good workability. Further, when frame engaging pieces are erected on both side edges of each inclined plate portion of the upper surface plate, at the time of construction, the upper side frame material of the roof panel placed on the hardware is received by the frame engaging pieces in a hooked state. be able to. Therefore, the eaves girders and the roof panels on the roof panel support of each roof frame are prevented from sliding down, and in this non-slip state, bolting work of the panel frame to each roof panel support can be performed. . Therefore, the fixing work of the roof panel can be easily performed. When each roof panel support metal member is made of cast metal, the accuracy of the metal member can be improved, and the roof assembly accuracy can be improved.
