DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof structure in a unit house. More specifically, the present invention relates to a roof structure of a unit house in which house unit rows in which a plurality of box-shaped house units are arranged in tandem are vertically stacked in a stepwise manner.

[0002]

2. Description of the Related Art In a unit house, a box-shaped house unit or a roof unit manufactured in advance in a factory is transported to a construction site by a truck or the like, where they are sequentially stacked upward and built. That is, a plurality of box-shaped housing units are installed on a foundation to form a living room, and then a roof unit is installed on these housing units.

Therefore, in assembling a unit house, housing units are built up by being stacked upward.
For example, when assembling a two-story unit house,
After the housing units on the first floor living room are installed on the foundation, the upper and lower joining plates are inserted into guide pins provided at the upper ends of the adjacent columns of these housing units, thereby positioning these housing units with each other. After the housing units on the second floor living room are installed in accordance with these guide pins, the housing units corresponding to the upper and lower sides are connected to each other.

In installing the roof unit, the upper and lower joining plates are inserted into guide pins provided at the upper ends of the adjacent columns of the housing unit on the second floor living room, thereby positioning these housing units with each other. After the roof unit is installed in accordance with these guide pins, the two-story house unit and the roof unit corresponding to the upper and lower sides are interconnected.

[0005]

As described above, the conventional unit housing has a structure in which the housing units corresponding to each other vertically are connected to each other, so that the proof strength against the horizontal force is lower than the proof strength against the vertical load.

In addition, since each roof unit has a structure in which only the bottom (floor side) is connected to a house unit below the floor (ie, a house unit for the second floor), adjacent roof units are positioned and connected to each other. It is necessary to provide a connection plate for the connection. This requires time and effort for assembling the connecting plate between the adjacent roof units, which takes time for the assembling operation.

Moreover, even if each roof unit is transported together with the box-shaped housing unit to the building site, since each roof unit is in a unitized form, that is, a bulky form, the transportation efficiency is poor and the transportation cost is high. There is also a disadvantage.

It is an object of the present invention in view of such prior art that it is possible to improve the proof strength against horizontal force, to perform the assembling work more efficiently, and to reduce the transportation cost. An object of the present invention is to provide a roof structure of a unit house that can be used.

[0009]

SUMMARY OF THE INVENTION Therefore, a roof structure of a unit house according to the present invention is a roof structure of a unit house in which a plurality of box-like house units are vertically arranged in a stepwise manner in a housing unit row. Two adjacent box-shaped houses in which roof panels with braces arranged diagonally are arranged on each floor in tandem between the upper-floor house unit row and the lower-floor house unit row that are stacked in the vertical direction. It is characterized by being attached across units.

[0010]

First, a housing unit row in which a plurality of box-shaped housing units are arranged in cascade is vertically stacked in a stepwise manner to form a unit housing. Lastly, two adjacent boxes in which roof panels with braces arranged diagonally are arranged in columns on each floor between the upper-floor housing unit row and the lower-floor housing unit row that are vertically stacked in a stepwise manner. It is installed across the housing units.

Therefore, the roof panel is mounted between the upper-floor housing unit row and the lower-floor housing unit row, so as to straddle between two adjacent box-shaped housing units arranged in tandem on each floor. Two adjacent box-shaped housing units in the upper-floor housing unit row and two adjacent box-shaped housing units in the lower-floor housing unit row can be connected to each other, and the adjacent roof units can be connected to each other in a conventional manner. It is not necessary to use a connecting plate or the like.

In addition, since the roof panel has a diagonal brace, and forms a truss with the side surfaces of the upper-floor housing unit row and the upper surface of the lower-floor housing unit row, the roof panel has a resistance to horizontal force. Can be improved. In addition, since the roof panel has a flat shape, the transportation efficiency is high, and a reduction in transportation cost can be expected.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a front view of the unit house of the present embodiment. As shown in FIG.
Is a living room part 2 constructed by sequentially stacking the first-floor housing unit row 11, the second-floor housing unit row 12 and the third-floor housing unit row 13 upward, and attached to the slope of the living room part 2 in a mountain shape. Roof panel 3.

Here, each row of housing unit rows 11, 1
2 and 13, as shown in FIG.
) Box-shaped housing units 4 are arranged in tandem in the longitudinal direction. Although the detailed structure of each box-shaped housing unit 4 is not shown, the upper and lower ends of four pillars arranged at the four corners are connected by four upper beams and lower beams, respectively. It is manufactured by forming a box-shaped skeleton and attaching inner and outer walls, ceiling materials, floor materials, etc. to appropriate places of the skeleton.

The living room section 2 has five first-floor housing unit rows 11, three second-floor housing unit rows 12, and one third-floor housing unit row 13 stacked one on top of the other. It is constructed in a triangular form. Therefore,
Housing unit rows 11, 12, and 13 constituting each floor are stacked in a staircase shape.

The roof panel 3 is, as shown in FIG.
An L-shaped ridge side roof panel 21 attached to the upper surface of the floor housing unit row 13 and a second floor housing unit row 12
And a total of four wife-side roof panels 22 attached to the wife side on the staircase side of the first-floor housing unit row 11, and a total of four girder-side roof panels attached between the front and rear wife side roof panels 22 23.

As shown in FIG. 3, the girder roof panel 23 includes a roof frame 24 formed in a rectangular frame shape, and a roof material 25 attached to the outer surface of the roof frame 24.
And a brace 26 provided at a diagonal position of the roof frame 24.

With such a configuration, in order to construct the unit house 1, first, a total of five first-floor house unit rows 11 are installed adjacent to each other on a foundation (not shown).
Subsequently, after a total of three second-floor housing unit rows 12 are installed on each of the first-floor housing unit rows 11 except for the first-floor housing unit rows 11 on both sides, a central second-floor housing unit is provided. The third-floor house unit row 13 is installed on the row 12, and finally the roof panel 3 is mounted. In addition, installation of these housing units 11, 12, and 13 is performed using an upper and lower joining plate as in the conventional case.

In mounting the roof panel 3, first, the ridge-side roof panel 21 is mounted on the upper surface side of the third-floor house unit row 13, and then, between the respective stairs side house unit rows 11, 12, and 13. The girder-side roof panel 23 is attached across two box-shaped housing units 4 arranged in tandem on each floor. Finally, the wife-side roof unit 22 is attached to both sides.

Therefore, according to this embodiment, a housing unit row 1 in which a plurality of box-shaped housing units 4 are arranged in tandem.
In a unit house 1 in which 1, 12, 13 are vertically stacked in a stepwise manner, the space between the first-floor house unit row 11 and the second-floor house unit row 12 and the second floor, which are stacked in the up-down direction in a stepwise manner. Girder side roof panel 2 between the residential unit row 12 and the residential unit row 13 for the third floor.
