Description

Description Method of construction work to convert to a rooftop house

The present invention relates to a construction method for renovating an existing house into a rooftop house. Background art

In recent years, there has been growing interest in houses with a rooftop in response to changes in the living environment and lifestyles, and renovations to remove the rooftops of existing houses and provide a rooftop are increasing. In the past, when renovating, the roof-to-ceiling was completely removed, and the rooftop was constructed in the same way as for new buildings.

For this reason, the above-mentioned conventional rebuilding method requires a longer construction period, and the construction cost is correspondingly higher. In addition, they could not live during the construction period, so they had to secure a place to live during that time, which placed a heavy burden on residents both mentally and financially.

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 conventional renovation methods could not overcome the above drawbacks. Furthermore, if proper roofing materials are not used, there is a risk of rain leakage.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and provides a construction method capable of easily remodeling an existing house into a house with a rooftop in a relatively short period of time, and having excellent livability after the remodeling. That is the task. Disclosure of the invention

The method of construction work for renovating a house with a roof according to the present invention is as follows. A support base mounting step of mounting a roof floor material support base on the arranged cross-section corrugated plates, and a roof floor floor material laying step of laying a roof floor material on the support base. I have.

In the case of a typical Japanese house, the roof removal process of removing the roof to expose the beam, the frame process of forming a frame with a square beam on the beam, and a folded plate with a corrugated cross section on the frame without gaps After going through the folding plate mounting process, which is to be installed side by side, the work for the support base mounting process and the roof floor laying process will be performed. If the roof is made of folded plates with a corrugated cross section, as in a prefabricated house, the existing folded plates can be used as they are, and the roof removal process, framing process and folded plate mounting process can be omitted.

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 the groove direction of the folded plate, practically preferable results are obtained.

In this case, a cylindrical body having an internal thread formed therein with an internal thread is projected upward from the folded plate, and a through-hole is formed in the C-shaped steel corresponding to the position of the cylindrical body, and inserted into the through-hole. If a method is used in which the threaded male screw is screwed into the female screw of the cylindrical body and a C-shaped steel is attached to the folded plate, the C-shaped steel serving as the support base can be easily attached.

Hereinafter, the present invention will be described in detail with reference to an example of a work of renovating an existing house A shown in FIG. 1 to a house B with a roof shown in FIG.

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

Next, as shown in FIG. 4, a frame is formed on the beam 2 with the square bar 4 (framing process). In the illustrated embodiment, a steel pipe 4 is used as a square bar, which is assembled in a lattice shape. As shown in Fig. 5, 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 a horizontal steel pipe 4 (2) are connected. Should be fixed with bolts 6 and nuts 7.

In addition, as a pre-process of the next folded plate mounting process, a folded plate support 8 is mounted on the upper surface of the steel pipe 4 as shown in FIG. A male screw rod 9 is provided on the top of the folded plate support 8 so as to protrude upward.

Then, as shown in FIG. 7, the folded plates 10 having a corrugated cross section are arranged without gaps on the framework of the steel pipe 4, and the male screw rods 9 are inserted into the through holes 10a formed in the folded plates 10. After inserting, the washer 11 is fitted to the male screw rod 9 and the nut 12 is screwed on to attach the folded plate 10 in a fixed state (folded plate attaching process). Adjacent folded plates 10 are not fixed. If the folded plates 10 are lined up with a steep slope in the groove direction, drainage is good.

Furthermore, at the upper end side of the male threaded rod 9 from the nut 12, and at the inner periphery, the female thread 13 a The cylindrical body 13 formed with is screwed. In the screwed state, the upper end of the cylindrical body 13 is higher than the upper end of the male screw rod 9. Therefore, the cylindrical body 13 having the female screw 13a formed on the inner peripheral part is in a state of protruding upward from the folded plate 10. Further, the length of the cylindrical body 13 is determined such that the upper end position of the cylindrical body 13 has a positional relationship described later with the C-shaped steel 14.

Next, as shown in FIG. 8, a support 14 for a rooftop material is disposed on the folded plate 10 so as to intersect the groove direction of the folded plate, and a through hole 14 formed in the support is provided. A port 15 as a male screw body is passed through a from above, and this is screwed into the female screw 13a of the cylindrical body 13 to attach the support base 14 (support base mounting step). A C-shaped steel is used as the support 14, and the C-shaped steel is arranged so that the opening is on the lower side. Since the upper end of the cylindrical body 13 is almost in contact with the lower surface of the C-shaped steel, it is easy to align the port 15 with the female screw 13a.

Finally, as shown in FIG. 9, the rooftop material 16 is laid on the support base 14 (rooftop material laying process). As shown in FIG. 10, the roof flooring material 16 has a flat plate-shaped first hanging part 16a formed at one edge, and the bottom surface level at the other edge. It has a shape in which a second hanging part 16b having a groove substantially the same as the level of the lower end of the hanging part 16a is formed. Lay each flooring material 16 in a state where the first hanging material 16a of the adjacent roofing material 16 fits into the groove of the second hanging material 16b, and support it with the screw-type fastener 17 Stick to 14 Thus, even if water enters between the adjacent roof floor materials 16, the water is received in the groove of the second hanging part 16 b and does not enter the interior any more.

In the house B with a rooftop constructed in this way, two spaces are formed between the ceiling material 3 and the rooftop flooring material 16 by the folded plate 10 so as to be superior in heat insulation. In addition, since the C-shaped steel is used as the support 14 for the rooftop material, the space between the ceiling material 3 and the rooftop material 16 is widened, and the structure is effective for heat insulation.

The above is an explanation of how to convert a general Japanese house into a rooftop house. However, the present invention is applicable to other than Japanese houses. For example, when the roof part is formed by folded plates 10 with a corrugated cross section as in the Blehab house shown in Fig. 11, the existing folded plate 10 is used as it is, and the roof removal process, frame process and The folding plate mounting process can be omitted. Industrial applicability

As described above, according to the construction method for renovating a house with a roof according to the present invention, since the roof is constructed without dismantling the ceiling, the construction period is short, the construction cost is low, and the construction is underway. Can also live. In particular, when the roof is made of folded plates with a corrugated cross section, as in a prefabricated house, the existing folded plates can be used as they are and the construction is simplified. Also, in a house renovated or fitted with a rooftop by the method of construction according to the present invention, the space between the ceiling and the rooftop flooring can be widened, so that a good living environment with excellent ventilation and heat insulation can be provided. can get.
