Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for supporting a boundary wall in a building.

[0002]

2. Description of the Related Art FIG. 3 shows a conventional structure of the upper end of a field wall. In the figure, (1) is a steel frame beam made of H-shaped steel, and a downwardly concave field wall support runner (2) is fixed to the lower surface of the steel frame beam (1), and a refractory material ( The upper end of 3) is inserted and attached, and the upper end of the face wall surface plate (4) is fixed to the outside of the runner (2). A cover plate (5) is also provided on the side surface of the beam (1) from the lower surface of the beam (1) on both sides of the runner (2).
The steel beam (1) is covered with the steel beam (1) so as not to be exposed.

DISCLOSURE OF INVENTION Problems to be Solved by the Invention In collective housing such as apartments, it is required that the boundary wall between the dwelling units has a fireproof structure. At that time, if a steel frame beam passes through the upper end of the boundary wall, the steel frame beam also needs to be covered with a refractory material.
In this case, in the above-mentioned conventional structure, the beam (1) cannot be covered because the cover plate (5) covers the beam (1).

According to the present invention, in which the conventional inconvenience is solved, a steel frame beam passes through the upper end of the boundary wall and the periphery of the steel frame beam is covered with a refractory material. An object of the present invention is to provide a support device for a boundary wall, which allows a plate and a boundary wall support runner to be fitted and attached well.

[0005]

[Means for Solving the Problems] In a structure in which the periphery of a steel frame beam is covered with a refractory material, a runner bracket having substantially the same height as the refractory material is exposed on the lower surface side of the refractory material on the lower surface side of the refractory material. And the flanges protruding to both sides in the horizontal direction at the lower end of the bracket and the field wall support runners protruding downward are supported by the bracket.
It is characterized in that the periphery of the refractory material is covered with a surface plate.

[Example] In FIG. 1, (11) is a beam made of H-shaped steel, and the floor panel (12) (12) end made of concrete plate on the upper surface of the beam (1) is the boundary with the upper floor. Parts are placed and installed. As shown in FIG. 2, the main body (15) has a U-shaped cross section with its upper side open, and its upper and lower ends are bent horizontally and its horizontal piece (16) is formed. Bend both ends of (16) vertically upward, and invert the upper ends of the vertical parts (18) and (18) toward the inside.
The receiving metal fittings (14) that are folded back in a V shape are shown. Then, the receiving metal fitting (13) is connected to the lower flange (17) of the beam (11) from the lower side to the vertical portion (18).
(18) is fitted so as to be sandwiched between them. At this time,
The engagement portion (14) projects toward the upper surface of the flange (17) to prevent the flange (17) from falling downward. In this state, the U-shaped main body (15) is replaced by the flange (1
7) protruding downward from the bottom surface of the main body (1
The lower surface of 5) is overlapped with the support flanges (19) projecting to the left and right sides in the wall wall pressure direction, and the U-shaped runner (20) with the lower side open is further stacked below it. Then, these are integrally fixed to the main body portion (15) of the receiving metal fitting (15) with screws or the like.

The left and right ends of the support flange (19) are vertically bent upward, and the vertical portions (22) (2
Between the outer surface of (2) and the downward U-shaped upper support metal fitting (23) attached to the lower surface of the floor panel (12), the surface plates (24) (24) on both sides are attached to the surface plate ( 24) The upper ends of (24) are inserted and mounted in the upper support fitting (23). Further, the lower surface plate (25) is provided on both sides of the runner (20) so as to follow the lower surface of the support flange (19).
(25) is installed.

Then, in the outer peripheral portion of the beam (11) covered by the surface plates (24) (25), from the side surface of the beam (11), both side surface portions of the main body portion (16) of the receiving metal fitting (15). A refractory material (27) (27) is placed over the beam to cover the beam (11). At this time, the lower end of the refractory material (27)
The horizontal part (1) below the lower flange (17) of the beam (11).
It is inserted into the gap (30) between the support flange (19) and the support flange (19) and supported.

A boundary wall refractory material (28) is attached to the runner (20) such that the upper end of the runner (20) is inserted into the runner (20). The boundary wall surface plates (29, 29) are attached so as to be in contact with each other to form a boundary wall portion.

[0010]

As described above, according to the present invention, the runner bracket is projected on the lower surface of the beam, and the cover plate is attached to the flange projecting to both sides from the lower end of the bracket. The refractory material can be stored in, and the cover plate and the refractory material can be stored and attached well. Further, by storing the end portion of the refractory material in the gap between the cover plate and the beam, the end portion of the refractory material can be reliably supported.
