Description

  The present invention relates to a sash frame mounting structure.

When a sash frame for a sweep-out window is to be assembled in a building, as described in Patent Document 1, a wall panel is placed on the floor panel and the foundation arranged on the foundation with the upper end face being opened outside. The lower frame of the sash frame protruding below the upper surface of the semi-base is fitted into a recess formed in the upper surface of the central portion of the semi-base. Thus, the inner surface of the sash frame is flush with the floor surface of the floor panel.
Patent 3112224

  In the sash frame mounting structure described in Patent Document 1, the lower frame of the sash frame is fitted into a recess formed in the semi-base, and the cross-sectional strength of the semi-base is weakened due to the formation of the recess, resulting in insufficient strength. There is a fear.

  Further, in the sash frame mounting structure described in Patent Document 1, the lower frame of the sash frame is simply stored in the weakened concave portion of the semi-base, and there is no consideration for firm mounting of the sash frame.

  An object of the present invention is to stably attach a sash frame for a discharge window to the front side of a floor frame assembly.

The invention of claim 1 is a sash frame mounting structure in which a sash frame for a sweep window is mounted on the front side of a floor frame in a factory-produced floor panel, and the floor frame of the floor panel manufactured in the factory is low in floor joists. It consists of three layers of joists and reinforced joists, with low joists and reinforced joists installed on both sides of the floor joists, making the heights of the floor joists and reinforced joists the same, The upper surface of the low joist that is lower than the height of the floor joist and the reinforcing joist and is attached to the range corresponding to the length of the sash frame provided on the front side of the floor joist forms a low step portion with respect to the upper surface of the floor joist And a sash body provided with a reinforcing joist in the range corresponding to the length at which at least the low joist is provided on the rear side of the floor joist, and provided with the guide rail for the inner sliding door and the guide rail for the outer sliding door of the sash frame. On the floor joists that make up the floor panel The sash lower frame portion provided on the front side of the sash main body portion in the sash frame and projecting downward from the sash main body portion and provided with the guide rails for screen doors is formed on the upper portion of the low joists constituting the floor panel. It is arranged at the low step part .

  According to a second aspect of the present invention, in the first aspect of the present invention, the reinforcing joist is a mounting portion for a sash body portion of the sash frame.

  A third aspect of the present invention is a floor panel having the sash frame mounting structure according to the first or second aspect.

  The invention according to claim 4 is a building unit configured by joining a wall panel to the floor panel according to claim 3.
