Description

Description: [Industrial field of application] The present invention relates to a structure for attaching a roof of an extension part to an existing part when an extension of a lower house or the like.

[Conventional technology]

Conventionally, in a large-scale skin panel construction method, as shown in FIGS. 10 (A), (B), and (C), there are cases in which lower sheds 71, 72, 73 are added to an existing building body 70.

[Problems to be Solved by the Invention]

The conventional roof panels of the extension parts 71, 72, 73 (Fig. 10) and the structure of the attachment parts 74, 75, 76 of the building body 70 dismantle the existing frame structure and add the extension parts 71, 72, 73. Is reconstructed into a frame structure that can be attached. For this reason, it took a lot of time and effort to attach the roof of the extension part, and the workability was poor.

Therefore, the present invention is to provide a roof mounting structure for an extension part having good workability.

[Means for Solving the Problems]

The roof mounting structure of the extension part of the present invention is a building body composed of outer walls of upper and lower floors connected via a connecting member and a floor connected to the connecting member, and an L-shape fixed to the outer wall of the upper floor and the floor. L fixed to the upper mounting part, the outer wall of the lower floor and the floor
Bottom mounting portion of the shape and mounting members parallel to the wall thickness direction are provided on the upper and lower mounting portions, respectively, and the mounting members of the upper and lower mounting portions are connected to each other, and the mounting member of the mounting member. The roof beam of the extension part attached to the.

[Action]

The roof mounting structure of the extension part of this invention is to install a mounting member between the outer walls of the upper and lower floors of the building body, and to attach the roof beam of the extension part to this mounting member. It is divided and can be easily installed between the outer walls of the upper and lower floors without dismantling the existing building body.

〔Example〕

An embodiment of the present invention will be described with reference to FIGS.

In FIG. 1, 10 is a building body, 11 is an extension part, 12 and 13 are outer wall panels on the upper and lower floors of the building body, and 14 is a floor panel. Outer wall panel 12 on the upper and lower floors,
The panel 13 and the panel 14 are connected to each other by bolts and nuts 16 via a connecting member 15 (FIG. 2) having a U-shaped stiffener. A mounting member 17 (FIG. 1) for extension is installed at a place where the connecting member 15 is not installed. The mounting member 17 includes an upper mounting portion 18 and a lower mounting portion 1.
It is divided into 9 and. As shown in FIG. 3, the upper mounting portion 18 is made of an L-shaped steel having a pair of mounting pieces 20, and each of the pieces and the mounting piece 20 have bolt insertion holes 21, 22, 23.
Are formed. The lower mounting portion 19 is made of L-shaped steel having a pair of mounting pieces 24, as shown in FIG.
Bolt insertion holes 25, 26, 2 in each piece and mounting piece 24
7 are formed. The upper mounting portion 18 has a bolt insertion hole 21.
Insert the bolt 28 into the lower frame of the outer wall 12 on the upper floor,
The lower mounting portion 19 has bolts 29 inserted through the bolt insertion holes 25 and fastened to the upper frame of the outer wall 13 on the lower floor. Further, the lower bolt insertion holes 26 of the lower mounting portion 19 and the outer frame of the floor panel 14 are fixed by bolts and nuts 30, and the upper bolt insertion holes 26 and the bolt insertion holes 22 of the upper mounting portion 18 and the floor are fixed. The outer frame of the panel 14 is fixed with bolts and nuts 31. Further, the bolt insertion hole 23 of the mounting piece 20 and the bolt insertion hole 27 on the upper side of the mounting piece 24 are connected by a bolt / nut 32. 5 and 6 show a cross-sectional view and a front view of the installation state of the mounting member 17.

Reference numeral 33 in FIG. 1 is a roof beam of the extension part. Roof beam 33
As shown in FIG. 7, the U-shaped steel 35 is welded to the end of the I-shaped steel 34, and the bolt insertion holes 36 are formed in both flanges of the U-shaped steel 35. In the roof beam 33, the U-shaped steel 35 is fitted onto the mounting piece 24, and the bolt insertion holes 27, 3 are formed.
6 Connect each other with bolts and nuts (not shown),
Mounted. In addition, as shown in FIG. 8, the roof panel 37 of the extension part is installed via the fixed metal fitting 38 fitted to the I-shaped steel 34 of the roof beam 33.

According to the roof mounting structure of the extension part configured in this way,
The extension section 1 through the mounting member 17 installed on the building body 10.
One roof beam 33 can be attached. Moreover, since the mounting member 17 is divided into the upper and lower mounting portions 18 and 19, even if a part 39 of the lower frame of the outer wall 12 of the upper floor hangs down, the upper and lower floors are not disturbed by the hanging portion 39. The outer wall 12, 13 can be easily fitted and attached. Therefore, the roof beam 33 can be attached without disassembling the existing building body 10, and the workability is improved.

As shown in FIG. 9, the upper and lower outer wall panels 12, 1
The connecting member 40 that connects the floor panel 14 to the outer wall 1
It may be a groove-shaped barrel insert extending in the width direction of 2 and 13, and in this case, the mounting member 17 is installed inside the connection member 40.

〔The invention's effect〕

The roof mounting structure of the extension part of this invention is to install a mounting member between the outer walls of the upper and lower floors of the building body, and to attach the roof beam of the extension part to this mounting member. Since it is divided, it can be easily installed between the outer walls of the upper and lower floors without dismantling the existing building body, and the workability is improved.
