Description

[Detailed description of the invention] [Technical field] This invention utilizes joint hardware installed between the exterior wall panel on the lower floor and the exterior wall panel on the upper floor at the corner of an existing building when extending the building. This invention relates to a structure for attaching an upper floor panel for an extension.

[Background technology] Conventionally, when extending a two-story building, floor panels on the upper floors of the building to be added are connected to the structural members of the existing building, but this method has poor workability and lacks strength. The problem was that it was not sufficient.

[Purpose of the invention] The present invention has been made in view of the above points, and provides a mounting structure for an upper floor panel for an extension, which allows the installation of an upper floor panel for an extension with ease and strength. The purpose is to

[Disclosure of the invention] In other words, the mounting structure of the upper floor panel for extension of the invention is such that the joint hardware 2 is installed between the outer wall panel 1 on the lower floor and the outer wall panel 1 on the upper floor at the corner of the building, and the joint hardware 2 is connected on both sides. One connecting part 4 of a connecting hardware 3 having parts 4, 4 is fixed to the joint hardware 2, and an upper floor panel 13 for an extension is attached to the other connecting part 4 of the connecting hardware 3, The above object is achieved by using the joint hardware 2 attached to the existing building and attaching the floor panel 13 on the upper floor via the connecting hardware 3 when building an extension.

The present invention will be described in detail below based on illustrated embodiments. FIG. 1 shows an overall perspective view of the first floor of the existing building with the ceiling removed, and the structure of the corner section of the building (section A in FIG. 1) will be described below. As shown in Figure 2, in the existing building, the lower floor exterior wall panel 1 and the upper floor exterior wall panel 1 at the corner part
A joint hardware 2 is attached between the two.
This joint metal fitting 2 is formed by fixing a base piece 6 and a vertical piece 7 between an upper piece 8 and a lower piece 9 of a plane L shape, and the base piece 6 is attached to both sides of the floor panel 13 of an existing building by welding nuts or the like. The upper piece 8 and the lower piece 9 are fixed to the downstairs exterior wall panel 1 using fixing tools 11 such as bolts and nuts.
And it is fixed to the mounting fittings 10 of the upper floor external wall panel 1 (that is, the panel frame constitutes the mounting fittings 10) with fixing tools 11. In this way, the joint hardware 2 is attached between the outer wall panels 1 and 1 on the lower and upper floors at the corner of the building, and before construction, the joint hardware 2 is installed between the outer wall panels 1 and 1 as shown in Figures 3 to 5. Pillar cover 1 that can be attached to
4 and a curtain plate 15. Reference numeral 18 in the attached drawings indicates the foundation.

Now, when extending a two-story building, the pillar cover 14 and curtain board 15 are removed to expose the joint hardware 2, and the connecting hardware 3 is attached to the joint hardware 2. As shown in FIG. 6, the connecting hardware 3 is a large metal fitting 2 having a U-shaped cross section.
A small metal fitting 22 is fixed to the inside of the joint metal fitting 2 by welding or the like, and connection parts 4, 4 are provided on both sides.As shown in FIG. The upper and lower connecting pieces 23, 23 of the connecting part 4 are inserted between the piece 8 and the lower piece 9 and fixed to the upper piece 8 and the lower piece 9 of the joint hardware 2 with fixing tools 11 such as welding nuts or bolt nuts. As shown in the figure, the base piece 12 of the connecting portion 4 of the small metal fitting 22 is fixed to the vertical piece 7 of the joint metal fitting 2.
At that time, the connecting portion 4 of the large metal fitting 21 will protrude to the outside from the outer wall of the existing building. The corner part of the upper floor panel 13 for extension is fixed to the base piece 27 of the connection part 4 of this large metal fitting 21 with the fixing tool 11, and the outer wall panel 1 for extension is fixed to the connection piece 25. In addition, in Fig. 8, the upper floor outer wall panel 1 of the existing building and the upper floor outer wall panel 1 of the extension part are shown.
are shown by dashed lines; the former is secured by a fixing tool by placing the end on the upper piece 8 of the joint hardware 2, and the latter is secured by placing the end on the connecting piece 25 of the large metal fitting 21. It will be fixed by a fixing tool.
In addition, part B in FIG. 7 shows the existing building, and part C shows the added building.

Therefore, when adding a two-story building, use the joint hardware 2 attached to the existing building.
By attaching the connecting hardware 3 to the joint hardware 2, the floor panel 13 for extension can be easily and structurally strong to be attached to the existing outer wall.

[Effects of the invention] As described above, the present invention installs a joint hardware between the exterior wall panel on the lower floor and the exterior wall panel on the upper floor at the corner of the building, and connects one joint of the joint hardware that has connection parts on both sides. was fixed to the above-mentioned joint hardware, and the floor panel for the extension was attached to the other connection part of the connecting hardware, so by attaching the floor panel for the extension to the joint hardware of the existing building via the connecting hardware, A second floor panel can be easily and firmly attached using joint hardware of an existing building.
