Description

[Detailed description of the invention] [Technical field] The present invention utilizes joint hardware installed between the exterior wall panels on the lower floor and the exterior wall panels on the upper floor of an existing building to provide reinforcement for the extension. The present invention relates to a structure for attaching a pillar to an extension floor.

[Background technology]

Conventionally, when extending a two-story building, the upper floors of the added building were connected to the structural members of the existing building, but this method was difficult to construct.
Furthermore, the mounting strength was not sufficient.

[Purpose of invention]

The present invention has been developed in view of the above points, and is a method for installing an upper floor flooring for an extension, which improves workability and allows for the installation of an upper floor flooring for an extension with structural strength. The purpose is to provide structure.

[Disclosure of invention]

In other words, the mounting structure of the upper floor tile for extension of the present invention is that the connecting hardware 3 is connected to the joint hardware 2 installed between the outer wall panel 1 on the lower floor and the outer wall panel 1 on the upper floor.
The joint hardware 2 is attached to the connecting hardware 3 to the outside, and a reinforcing pillar 4 is attached to the reinforcing pillar 4, and an upper floor sill 5 for an extension is attached to the reinforcing pillar 4. In the installation structure of the floor lining for the extension, in which the reinforcing column 4 is installed so as to protrude to the outdoor side when the building is extended, and the floor lining 5 for the extension is attached to the reinforcing column 4, the joint hardware 2 is placed on the outdoor side. It consists of a fixing metal fitting 6 that is open and has a substantially U-shaped cross section, and two parallel vertical pieces 7, 7 fixed between the upper piece 8 and the lower piece 9 of this fixing metal piece 6, and the connecting metal piece 3 is attached to the building side. It has a U-shaped cross section with an opening, and the pieces 16 on both sides are connected to the vertical pieces 7 of the joint hardware 2,
The above object is achieved by fixing the reinforcing column 4 to the outer surface of the mounting piece 17, with the central mounting piece 17 protruding outward from the outer wall of the existing building.

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 an existing building with the ceiling removed, and the structure of section A in FIG. 1 will be explained below. As shown in FIG.
is installed. This joint metal fitting 2 is formed by fixing vertical pieces 7 and 8 to a fixing fitting 6 having a substantially U-shaped cross section that opens to the outdoors, and the upper piece 8 and the lower piece 9 of the fixing fitting 6 are attached to the upper floor exterior wall panel. 1 and the mounting fittings 10 of the downstairs exterior wall panel 1 with fasteners 11 such as bolts and nuts, and the joint fittings 2
The base piece 12 is attached to the side surface of the downstairs floor panel 13 by the fixing tool 1.
It is fixed at 1. In this way, the joint hardware 2 is attached between the outer wall panels 1 on the lower floor and the upper floor, and before the extension, the column covers 14 and It is covered by a curtain plate 15.

Now, when extending a two-story building, the pillar cover 14 and curtain plate 15 are removed to expose the joint hardware 2, and the reinforcing pillar 4 is attached to the joint hardware 2 via the connecting hardware 3. 6th
As shown in FIG.
6 is fixed to the vertical piece 7 of the joint hardware 2 using a fixing tool 11 such as a welding nut or a bolt nut. At that time, the mounting piece 17 of the connecting hardware 3 will protrude to the outside from the outer wall of the existing building. The reinforcing column 4 is formed into a rectangular cylindrical shape and is fixed to the above-mentioned connecting hardware 3 by welding or the like, so that it is attached vertically for a long length along the outer wall of the building. As shown in FIGS. 6b to 6d, the lower end of this reinforcing column 4 is fixed to a fixing hardware 20 fixed to an anchor bolt 19 buried in the foundation 18 with a fastener 11 or the like. This reinforcing column 4 has a fixing tool 1 attached to the end of the upper deck 5 for extension.
1 is fixed, and the floor panel on the upper floor of the floor 5 is attached.

Therefore, when adding a two-story building, the joint hardware 2 attached to the existing building can be used, and the reinforcing columns 4 can be attached to the joint hardware 2 so as to protrude to the outside. This makes it possible to pass the reinforcing columns 4 between the existing outer wall and the extension side outer wall. In FIG. 5, part A shows the part where the reinforcing column 4 is attached, part B shows the existing building, and part C shows the added building.

[Effect of idea]

As mentioned above, the present invention involves attaching a connecting hardware to the joint hardware attached between the downstairs exterior wall panel and the upstairs exterior wall panel, protruding toward the outdoors, and attaching a reinforcing column to the connecting hardware. In the installation structure of the upper-floor flooring for extensions, the joint hardware is fixed between the fixing bracket with a roughly U-shaped cross section that opens to the outdoors, and the upper and lower pieces of this fixing bracket. The connecting hardware has a U-shaped cross section that opens toward the building, and the two side pieces are fixed to the vertical pieces of the joint hardware, and the central mounting piece is attached to the roof from the outside wall of the existing building. Since the reinforcing pillars were made to protrude outward and fixed to the outer surface of the mounting piece, the existing joint metal fittings that are always present when connecting the upper and lower floor exterior wall panels were used as they were, and the connecting metal fittings of the joint metal fittings were fitted into the joint fittings. It can be fixed, so the fixed position of the connecting metal fittings to the joint fittings can be determined reliably, and
The connecting hardware is configured to correspond to each reinforcing column to be attached, and since it is compatible with existing joint fittings, the standards for the connecting hardware have been established, and the cost is low. Furthermore, the installation strength of the connecting hardware can be adjusted to any location. Therefore, the reinforcement columns can be structurally strongly fixed, and as a result, the upper floors for extensions can be structurally strongly attached.
