Description

The present invention relates to a smoke-proof basin wall in which a smoke-proof sheet is used.

Conventionally, a smoke-proof wall having corners laid out so that smoke-proof sheets and smoke-proof panels intersect is known. For example, Patent Document 1 and Patent Document 2 disclose this type of smoke-proof wall. Patent Document 1 describes a structure in which a polygonal reinforcing material is used to connect a mullion for fixing a non-combustible sheet and an L-shaped angle for the ceiling to a corner of a smoke-proof wall. Further, in Patent Document 2, in a smoke-proof wall in which two or more units are connected in an L-shape, a T-shape, a cross shape, etc., each unit is connected via a continuous portion. The structure in which the non-combustible sheet is stretched in a laterally tensioned state is described.

By the way, from the viewpoint of design, there are cases where it is desired to set the angle at which the smoke-proof sheets constituting the corners intersect in order to prevent wrinkles and bending of the smoke-proof sheet and to match the structure of the building to be installed. .. In this regard, in the configuration of Patent Document 1, since the construction angle is determined by the angle of the corner reinforcing metal fittings, the corner portion is fixed with wrinkles and bending of the smoke-proof sheet depending on the installation location and situation. Become.

In Patent Document 2, tension is applied so that the continuous portion is held in an upright state so that a predetermined angle is maintained in a state where tension is applied to the sheets of the smoke-proof basin walls on both sides of the continuous portion (corner pillar). The function of adjusting the angle is also described as well as the arrangement of the tension applying mechanism (wire) for applying the smoke. However, the corner part is a single pillar, and smoke-proof sheets are placed on both sides of the pillar, but in order to erect the pillar, the tension of each smoke-proof sheet and the tension of the wire You have to balance. For this tension balancing work, it is necessary to adjust the angle while installing it on the ceiling. Further, if the tension balance is lost due to expansion and contraction of the smoke-proof sheet, the corner portion may be tilted. Since it is necessary to adjust the tension balance in multiple directions, there is room for improvement in terms of workability and maintenance.

When a so-called tension-type smoke-proof wall that applies tension to the smoke-proof sheet is used, if the lengths of the two smoke-proof sheets arranged at the corners in the width direction are different, the length in the width direction is long. In this case, or when the angle of the corner is acute or obtuse, it is particularly difficult to properly balance the tension. For example, if the angle of the corner portion is an acute angle, the corner portion may be tilted in the pulling direction. In this respect, the conventional tension applying mechanism is for forming the shape of the corner portion aesthetically, and may not be able to withstand the strong pulling of the tension type smoke-proof sheet.

The arcuate portion 92 is a plate-like member having a curved surface whose cross-sectional shape is arcuate. The arc portion 92 is held via an extending portion 94 extending from the connecting side grip portion 93 in the longitudinal direction of the second smoke barrier wall 12. The curvature of the arc portion 92 is set according to the shape of the ring portion 82.

By punching out the screw 66 in a state where the arc portion 92 of the second connecting portion 91 is overlapped with the peripheral surface of the annular portion 82 of the first connecting portion 81, the first panel member 51 and the second panel member 52 are cornered. It is connected by 50. In a state where the first connecting portion 81 and the second connecting portion 91 are connected, the corner connecting member 80 reaches the ceiling 5.

It is eccentric. Further, the extending portion 94 of the second connecting portion 91 is located at a position away from the first panel member 51 with respect to the virtual line P2 passing through the center in the thickness direction of the second panel member 52. This makes it possible to bring the ends of the first panel member 51 and the second panel member 52 closer to each other. Further, depending on the installation location, it may be desired to make the angle formed by the first panel member 51 and the second panel member 52 an acute angle, but with this configuration, the first panel member 51 and the second panel member 52 are less likely to interfere with each other. Therefore, it is possible to make the angle smaller on the acute angle side.

The angle of formation can be adjusted, and the degree of freedom in the specifications of the smoke-proof wall 1 can be increased. Further, since the first panel member 51 and the second panel member 52 are both surrounded by a frame material around four circumferences and have rigidity, the angle can be determined more accurately. Further, the corner portion 50 can be attached to the ceiling 5 after adjusting the angle with the corner connecting member 80 in advance, or the angle can be adjusted while being attached to the ceiling 5, so that the degree of freedom in workability is improved. To do.

The angle formed by the first panel member 51 and the second panel member 52 is adjusted by the connection position of the arc portion 92 with respect to the peripheral surface of the annular portion 82.

As a result, the function of adjusting the angle can be realized with a simple configuration. Further, since the angle formed by the first panel member 51 and the second panel member 52 can be determined by the angle of the connecting position of the arc portion 92 connected to the peripheral surface of the annular portion 82, the work of adjusting to a desired angle. Can be easily done.

Further, in the present embodiment, the annular portion 82 is arranged at a position where the center of the circle is eccentric to the second panel member 52 side with respect to the center in the thickness direction of the first panel member 51.
