Description

[Detailed Description of the Invention] The present invention is applicable to a one-story building with a gable roof or a partially two-story building) (m, for example, when adding one space to the girder side of a sunroom, children's room, etc.) Point 1: We are proposing a construction method that is advantageous for both aspects of daily life.
This has a purpose.

When adding one girder side to a building with a gable roof,
Conventionally, as shown schematically in Figure 1, the entire roof component of the existing building was removed, the extension A' was constructed, and a new roof was then installed. Conventional construction methods such as (a) require a large number of construction man-hours and materials for new components, and in addition, each piece of construction work, including electrical wiring, has a great impact, not only prolonging the construction period but also requiring a large amount of materials, There are many aspects that are extremely uneconomical both in terms of construction costs, and (0) the existing buildings will not have roofs during construction, making it impossible to carry out daily life.

It had many drawbacks, such as:

In view of the current situation, the present invention has been devised to eliminate the above-mentioned drawbacks by minimizing construction work on the existing building and reducing the number of components used in the extension. be.

That is, in the method for extending a building with a gable roof according to the present invention 1, first, the wall of the extension is constructed, and then the roof constituent members of the extension are attached to the ends of the roof constituent members of the existing building. It is characterized by joining one piece to form a slope, and requires almost no modification to the roof of an existing building, electrical wiring, etc. It is possible to proceed with the planned extension work by simply performing the minimum necessary preparatory work such as removing the obstructive eaves.Moreover, the roof of the extension can be placed at the same slope as the roof of the existing part. Compared to constructing a new roof with a different slope (separately), adding a new roof with a new roof with a different slope.
Not only can materials, construction costs, and man-hours be significantly reduced, but also the loss of discarded parts resulting from disassembly can be kept to a minimum.

Therefore, the present invention has economical and constructional effects such as reduction of extension costs and shortening of construction period, as well as the effect of reducing incidental costs such as temporary housing, etc. as it has little impact on daily life inside the existing building. As a result of these synergies, we were able to propose an extremely economically advantageous construction method.

Hereinafter, Example 1 in which the construction method of the present invention was applied to an extension of a Heike building, Example 2 and (C) in which the construction method of the present invention was applied to an extension of a partially two-story building to a total of two floors when viewed from the gable side will be described.

Example 1 (See Figures 2 to 4) A one-story building with a gable roof as shown in Figure 2 is extended on the girder side to complete the building as shown in Figure 3.1 First, the extension is completed. Walls 1 and 2 on the girder side and girder side of part A are attached to the existing building B.
After constructing the building in such a way that it is connected to the wall 5, the roof component 3 of the extension A is joined to the tip of the roof component 4 of the existing building B by a single roofing method so that the roof component 4 has the same slope. , and these L2 and 4 are integrated.

After completion of such extension work, the wall 6 facing the extension side of the existing building B is removed.

Example 2 (See Figures 5 and 6) The second floor of a partially two-story building with a gable roof as shown in Figure 5 was added to the girder side, and the total area was increased as seen from the gable side as shown in Figure 6. To complete the two-story building, remove the roof component 3 on the lower floor and the girder side wall 1B on the second floor, which correspond to the extension part A) of the existing building B, and replace these 3B and IB with the extension part A). It is possible to reduce the number of parts required for an extension by repurposing the outer wall 1 and 31 roof constituent members of A.1 This is different from the case of Example 1 in this point, but the construction procedure is as described in 1. It is almost the same as

Note that the walls 1 and 2 use dedicated wall frames and external wall panels, but a detailed description of their construction will be omitted.

Further, although the construction method of the present invention is particularly effective for prefabricated buildings, it can be applied to buildings using any construction method.
