JP2002201800A - Method for rebuilding existing house into house with roof floor, and roof floor material - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a construction method which can easily rebuild an existing house into a house with a roof floor in a relatively short construction period, and improves the habitability of the house after rebuilding, and to provide a roof floor material which is suitable for use in the construction. SOLUTION: The construction method includes a roof removing step, a framing step, a folded plate mounting step, a bearing stand mounting step, and a roof floor material laying step. In the roof removing step, a roof of the existing house is removed and beams 2 are exposed. In the framing step, square timbers 4 are assembled into a frame. In the folded plate mounting step, folded plates 10 corrugated in cross section are arranged and mounted on the frame without clearances. In the bearing stand mounting step, a bearing stand 12 for the roof floor material is mounted on the folded plates 10. In the roof floor material laying step, the roof floor material 13 is laid on the bearing stand 12. The roof floor material 13 has a plate-like first hanging portion 13a which is formed at one edge thereof, and a second hanging portion 13b which is formed at the other edge thereof. The second hanging portion 13b has a groove whose bottom surface is almost the same in level as a lower edge of the first hanging portion 13a.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for renovating an existing house into a house with a roof, and a roofing material suitable for use in this work.

[0002]

2. Description of the Related Art In recent years, there has been an increasing interest in houses having a rooftop in accordance with changes in living environments and lifestyles, and renovations in which the rooftops of existing houses are removed to provide a rooftop are increasing. Conventionally, when performing this renovation, the entire area from the roof to the ceiling was completely removed, and the roof was constructed in the same way as for new construction.

[0003]

For this reason, the above-mentioned conventional rebuilding method requires a long construction period and a high construction cost. In addition, because they could not live during the construction period, they had to secure a separate place of living during that time, which placed a heavy burden on residents both mentally and financially.

[0004] In general, a rooftop house has a drawback that it has poor heat insulation because it has no roof. However, a rooftop house constructed by a conventional rebuilding method could not overcome the above drawbacks. . Furthermore, if an appropriate rooftop material is not used, there is a risk that rain leaks may occur.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and provides a construction method that can easily convert an existing house into a house with a roof in a relatively short period of time, and that has excellent livability after the remodeling. The task is to provide. It is another object to provide a rooftop material suitable for use in this construction.

[0006]

According to the present invention, there is provided a method of reconstructing a house with a roof according to the present invention, comprising the steps of removing a roof of an existing house to expose a beam, and forming a frame with a square beam on the beam. A framing step of assembling, a fold plate attaching step of arranging folded sheets having a cross-sectional waveform on the framework without gaps, a supporting table attaching step of attaching a support of a rooftop floor material on the folded plate, And a roof floor material laying step of laying a roof floor material on top.

In the above construction method, if a C-shaped steel is used as the support, and the C-shaped steel is arranged so that the opening is on the lower side and intersects with the groove direction of the folded plate, a practically preferable result is obtained.

In the roofing material according to the present invention, a flat first hanging portion is formed at one edge, and a bottom surface is formed at the other edge at a lower end level of the first hanging portion. A second hanging portion having a groove which is substantially the same as that of the first embodiment is formed.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, taking an example of a construction for renovating an existing house A shown in FIG. 1 to a house B with a roof shown in FIG. 2,
The present invention will be specifically described.

At the time of renovation work, first, the roof 1 of the existing house A is removed to expose the beams (roof removal step). FIG.
Is a perspective view of a construction site showing a state in which the roof removal process has been completed, and beams 2 arranged vertically and horizontally are exposed. The ceiling material 3 is left under the beam 2 as it is.

Next, as shown in FIG. 4, a frame is formed on the beam 2 with the square bar 4 (frame setting step). In the illustrated embodiment, a steel pipe 4 is used as a square member, which is assembled in a lattice shape. As a method for connecting steel pipes, for example, as shown in FIG. 5, an L-shaped connecting piece 5 is attached to a vertical steel pipe 4 (1) by welding, and the connecting piece 5 and the horizontal steel pipe 4 (2) are connected. Fix with bolts 6 and nuts 7.

In addition, as a process prior to the next folded plate mounting process,
As shown in FIG. 6, a folded plate support 8 is attached to the upper surface of the steel pipe 4. The folded plate support 8 is provided with a male screw rod 9a for attaching a folded plate and a male screw rod 9b for attaching a support base, which are projected upward from the top in advance.

Then, as shown in FIG. 7, a folded plate 10 having a corrugated cross section is arranged on the framework of the steel pipe 4 without any gap, and the male screw rod 9a is inserted into a hole formed in the folded plate. The nut 11 is screwed onto the rod 9a to attach the folded plate 10 in a fixed state (folded plate attaching step). The folded plates are not fixed.
If the folded plates 10 are arranged with a slight gradient in the groove direction, drainage is good.

Next, as shown in FIG. 8, the support 1 for the roof flooring material is placed on the folded plate 10 with the male screw rod 9b and the nut 11.
2 is mounted (support base mounting step). A C-shaped steel is used as the support 12, and the C-shaped steel is arranged so that the opening is on the lower side and crosses the groove direction of the folded plate 10.

Finally, as shown in FIG. 9, a rooftop material 13 is laid on the support base 12 (rooftop material laying step). As shown in FIG. 10, the roof flooring 13 has a flat first lower portion 13 a formed at one edge and a bottom surface at the lower edge of the first lower portion 13 a at the other edge. It has a shape in which a second hanging portion 13b having the same groove as the level is formed. Roof flooring 1 next to the groove of the second hanging part 13b
3 in a state where the first hanging portion 13a of the roof 3 is fitted.
Is laid, and is fixed to the support base 12 by the screw type fixing tool 14. As a result, even if water enters between adjacent roof floor materials, the water is received by the groove of the second hanging portion 13b and does not enter the interior.

The house B with a roof thus constructed is
Since two spaces vertically separated by the folded plate 10 are formed between the ceiling material 3 and the roof floor material 13, heat insulation is good.
Further, since the C-type steel is used as the support 12 for the rooftop material, the space between the ceiling material 3 and the rooftop material 13 is widened, and the structure is effective for heat insulation.

[0017]

As described above, according to the construction method for remodeling a house with a roof according to the present invention, since the roof is constructed using the existing beams, the construction period is short and the construction cost is low. In addition, since the ceiling is not dismantled, it becomes possible to live during construction. In addition, a large space can be provided between the ceiling portion and the rooftop floor material, so that the comfort after the renovation is excellent. Furthermore, when the roof floor material according to the present invention is used, it is possible to completely prevent intrusion of rainwater or the like, and to provide a rooftop house that does not leak water.
