BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the structure of a roof unit that is preassembled in a factory or the like to constitute the roof of a unit house.

0002

2. Description of the Related Art In order to construct a unit house, each unit to be assembled on-site is usually pre-assembled in a factory or the like.

[0003] The roof unit constituting the roof of a unit house is also preassembled in a factory or the like, and the roof unit is disclosed in Japanese Patent Application Laid-open Nos. 51-111721 and 1983.
It has a structure as shown in Japanese Patent No. 253637.

[0004] Such a roof unit has conventionally consisted of roof surface components such as upper chord members, diagonal chord members, and sheathing boards, and small girder walls,
It is constructed by assembling a small wall portion such as a small end wall and a reinforcing member such as a truss.

[0005] The small walls are assembled in advance in the pre-assembly process of the roof unit, but each girder small wall and end small wall are integrally formed according to the size of the roof unit to be constructed. It is formed of.

[0006]

[Problems to be Solved by the Invention] However, in conventional roof unit structures, the entire small wall section is always formed as one piece in the pre-process of the roof unit assembly process, which makes it difficult for large roof units or roof units with complicated shapes to be formed. In this case, the small wall portion becomes large or complicated.

[0007] Therefore, this results in an increase in the size of equipment (for example, transportation equipment for small wall units, etc.) during the roof unit assembly process and an increase in the weight of the small wall part. This increases the number of man-hours in the process and reduces factory productivity.

[0008] The present invention aims to solve these problems, and makes it possible to efficiently produce large roof units or roof units with complicated shapes using conventional factory equipment. The purpose of this project is to provide a roof unit structure.

[0009]

[Means for Solving the Problems] In order to achieve the above object, the roof unit structure of the present invention is constructed by assembling at least a roof surface constituent part and a small wall part, in which the small wall part is , is characterized in that it is formed from a plurality of small wall components that are assembled in advance in a process prior to the roof unit assembly process. In addition, the small wall components are configured by pasting face materials on the frame and can be interconnected.

0010

[Operation] In the above-described roof unit structure of the present invention, the small wall portion is divided into a plurality of small wall component parts, and each of the smaller wall component parts is assembled in the pre-process of the roof unit assembly process. Since it can be assembled in advance, even large roof units or roof units with complicated shapes can be easily produced using conventional factory equipment.

[0011]

[Embodiment] Hereinafter, a roof unit structure as an embodiment of the present invention will be explained with reference to the drawings. FIG. 1 is an exploded perspective view schematically showing the structure. 1. It is constructed by assembling the end small wall part 2, the girder small wall part 3, etc. In this embodiment, since the girder small wall part 3 is large, this girder small wall part 3, three small wall component parts 3a, which were preassembled in the pre-process (sub-assembly) of the roof unit assembly process.
It is formed from 3b and 3c.

Next, the assembly procedure of the roof unit 10 to which the structure of the present invention is applied will be explained with reference to FIGS. 2 to 5.

First, as shown in FIG. 2, the small wall constituent parts 3a, 3b, 3c are assembled in advance in a step before the roof unit assembly process, and these small wall constituent parts 3a
3c are combined to form the girder small wall portion 3 using joint hardware (not shown) or the like. At this time, each small wall component portion 3a, 3b, 3c is constructed by pasting a panel 12 to a frame 11, as shown in FIG. Then, the frame bodies 11 of the adjacent small wall constituent parts 3a, 3b, 3c,
11 are nailed together, and these frames 1
Each small wall component part 3a, 3b, 3c is connected to each other by nailing and fixing joint metal fittings (not shown) placed across 1 and 11.

In the girder small wall portion 3 formed in this manner, as shown in FIG. 3, after setting the structural joint material 4 at the tip of the small wall forming portion 3a,
The upper chord member (roof surface component) 5 is nailed and fixed along the horizontal upper edge of the small wall component 3a, and the diagonal chord member (roof surface component) 6 is nailed and fixed along the inclined upper edge of the small wall component 3a. .

As shown in FIG. 4, the end small wall part 2, which was also pre-assembled in the previous step of the roof unit assembly process, is fixed to the girder small wall part 3 by nailing, and then the end small wall part 2 is fixed to the girder small wall part 3. Truss the tip of the part 2 and the tip of the structural joint material 4 (
(reinforcing member) 7.

Furthermore, between the girder small wall portion 3 and the truss 7,
A beam 9 is interposed parallel to the structural joint material 4, and a plurality of beams (
The diagonal chord members 6 (three in the figure) are fixed.

After attaching the various members to the end small wall section 2 and girder small wall section 3 as described above, roofing boards etc. are attached along the upper chord members 5, diagonal chord members 6, etc., as shown in FIG. After forming the roof surface 1, seven divided gypsum boards 8a to 8g are nailed to the outer surface of the small girder wall 3. Although not shown in FIG. 5, a gypsum board is also nailed and fixed to the small end wall 2.

As described above, according to the roof unit structure of this embodiment, the girder small wall portion 3 has three small wall constituent portions 3a to 3c.
Each of the smaller wall component parts 3a~
The roof unit 10 is assembled every 3c in a pre-process of the assembly process of the roof unit 10.

Therefore, the size of the objects to be assembled (the small wall components 3a to 3c) in the pre-process of assembling the roof unit 10 can be reduced, which not only improves factory productivity, but also improves the productivity of large roofs. Even for roof units with complex shapes, new small walls can be easily produced using existing factory equipment.

Furthermore, by dividing the girder small wall portion 3, it is possible to create lightweight small wall component portions 3a to 3c, which facilitates transportation of each member and facilitates smooth assembly of the roof unit 10. Become so.

[0021] In the above embodiment, the structure of the present invention is applied to the girder small wall part 3, and the case where the girder small wall part 3 is divided into three parts is explained, but the structure of the present invention is limited to this. In addition, the present invention can be similarly applied to the end small wall portion 2, and the number of divisions may be two if the small wall is small, or four or more if the small wall is large or complicated.

Further, in the above embodiment, the case where the structure of the present invention is applied to the roof unit 10 having the shape as shown in FIG. Applies to. For example, Fig. 6(a)
~ Roof units 10A and 1 as shown in (c), respectively
In 0B and 10C, the structure of the present invention is applied by dividing each girder small wall portion 3A to 3C into three and configuring the small wall component members 3a, 3b, and 3c, and the same effects as in the above embodiment can be obtained. can get.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and even if there are design changes without departing from the gist of the present invention, they are included within the scope of the present invention.

Effects of the Invention As detailed above, according to the roof unit structure of the present invention, the small wall portion constituting the roof unit can be
The extremely simple structure is made up of multiple small wall components that are pre-assembled in the pre-roof unit assembly process, so even if the roof unit is large or has a complex shape, it can be easily constructed using conventional factory equipment. It has the effect of allowing extremely efficient production as it is.
