Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a mounting structure of a load bearing wall panel that enables a load bearing wall panel for an upper floor partition to be arranged on the outer wall side and enhances the rigidity of a house frame structure. .

[Conventional technology]

In a dry construction building, for example, as shown in FIG. 3, the tip end of a beam b extending from the upper end of a through pillar a in the house toward the eaves side and a bundle c rising from the beam b. A structure in which the use of eaves beams is eliminated by connecting a roof panel d to the upper end of ... and constructing a truss structure with the beam b, the bundle c and the roof panel d Many things are used.

Also, in this structure, usually, the tip of the beam b and the root of another beam b are connected by a brace f, and the beam b and the supporting member g therebelow are provided with a floor. By providing the load bearing wall panel P for the upper partition, the rigidity of the entire house frame structure h can be enhanced.

[Problems to be solved by the device]

However, this one cannot arrange the load bearing wall panel P on the tip side of the beam b, that is, on the outer wall side of the house because the mounting plate e for brace connection is conventionally provided on the lower surface of the tip of the beam b.
The rigidity of the house frame structure h was insufficiently strengthened.

According to the present invention, the load-bearing wall panel can be arranged on the outer wall side based on the provision of a projecting portion for connecting one end of the brace to the upper fixing piece of the joining metal fitting joining the load-bearing wall panel and the beam. The purpose is to provide a mounting structure for a load bearing wall panel that can solve the problems.

[Means for Solving the Problems]

In order to achieve the above object, the mounting structure of the load-bearing wall panel of the present invention is such that the upper end of the load-bearing wall panel whose lower end is connected to the horizontal support member of the house frame structure is parallel to and above the support member. A mounting structure for a load-bearing wall panel to be mounted on a beam material to be arranged using a joining metal fitting, wherein the joining metal fitting is a lower fixing piece fixed to an upper end of the load bearing wall panel, and a horizontal fixing part to be fixed to a lower surface of the beam material. An upper fixing piece, a lower fixing piece, and a bridging piece that joins the upper fixing piece together, and the upper fixing piece is formed with a series of protruding portions protruding beyond the lower side edge of the beam member, One end of a brace that reinforces the house frame structure is connected to this protrusion.

[Action]

As described above, since the metal fitting itself that connects the upper end of the load-bearing wall panel and the beam is provided with the protrusion for brace connection, the load-bearing wall panel should be arranged on the tip side of the beam, that is, on the outer wall side of the house. As a result, it becomes possible to directly support the roof load acting on the tip of the beam and the stress such as the tension of the brace by directly using the load bearing wall panels, and the rigidity of the house frame structure can be effectively improved. .

However, the side end portion of the roof panel 46 is connected to the tip end of the beam member 20 of the roof frame structure 19, the upper ends of the bundle members 21 and 22 and the diagonal member 23, and the connecting piece 45 at the upper end of the outer wall portion w1. The roof rigidity is maintained by the truss structure composed of the panel 46 and the roof frame structure.

As described above, since the joining metal fitting 1 used in the mounting structure of the load-bearing wall panel of the present invention has the protrusion 11 for connecting the brace 10 formed on the upper fixing piece 7 in series, the load-bearing wall panel 5A is attached to the outer wall side. The load-bearing wall panel 5A can directly support the roof load acting on the tip portion of the beam 20 and the stress such as the tension of the brace 10 and can significantly improve the rigidity of the entire house.

In this embodiment, the outer wall portion w1 may be formed by a load bearing wall panel, and the upper end of the outer through column 15 may be aligned with the upper surface of the floor beam 17A.

[Effect of device]

As described above, the mounting structure of the load bearing wall panel of the present invention has the protruding portion for connecting the brace to the joining metal fitting that connects the load bearing wall panel and the beam, so that the load bearing wall panel can be arranged on the outer wall side. The stress acting on the beam can be carried by the load bearing wall panel, and the rigidity of the entire house frame structure can be greatly improved. Further, since the projecting portion is formed in a series on the upper fixing piece of the joining metal fitting fixed to the lower surface of the beam member, it is possible to prevent interference between the ceiling material arranged at the upper end position of the load bearing wall panel and the brace. Since the house frame structure is reinforced by braces in the vicinity of the height of the lower surface of the beam member located higher than the upper end of the load bearing wall panel, the reinforcing strength can be effectively increased.
