Abstract

PURPOSE:To enhance the bending strength and improve the sound insulating property and fire resistance by arranging a non-combustible panel having a rib part integrated thereon with the rib part outside. CONSTITUTION:A pair of non-combustible panels 10 are arranged with ribs 22 outside (interior side). The ribs 22 are necessarily formed on both end parts of the non-combustible panel 10, and the panels 10 are built up by tongue and groove joint. A rock wool 55 which is a non-combustible sound absorbing material is inserted to a hollow layer 32 which is the space between both the non- combustible panels 10 to enhance sound insulating effect. A non-combustible plate 60 is laid on the rib 22 to form a space 40. Thus, a lightweight fire resisting sound insulating partitioning wall of three-layer structure is formed by the hollow layer 32 and both the spaces 40. Since the rib 22 faces outside, the sectional coefficient of the panel effectively works to provide the lightweight fire resistant sound insulating partitioning wall having high bending rigidity.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lightweight fireproof and sound insulating partition wall composed of a pair of noncombustible panels facing each other with their ribs facing outward.

[0002]

2. Description of the Related Art Conventionally, a concrete wall type partition wall has been used as a partition wall, but it is excellent in fire resistance and sound insulation, but it is heavy and expensive in a high-rise building. Therefore, partition walls made of various lightweight panels have been developed in recent years. In particular, those that emphasize sound insulation have been developed by adopting a method in which two independent walls are provided and making the independent walls themselves hollow panels or ribs in order to reduce weight. For example, in FIG.
JP-A-63-27645 (A) and JP-A-63-
The partition walls described in the publications of No. 118440 (B), No. 63-190417 (C), and Japanese Patent Application No. 3-13642 (D) have been proposed.

[0003]

In the conventional lightweight fireproof and soundproof partition wall shown in FIG. 6, the vertical ribs of the panel face inward and face each other, and a hollow layer is provided from both sides of the runner. ing. Therefore, the section modulus of the non-combustible panel is not effectively used in terms of bending strength. This is as shown in FIG. 7 (see FIG.
When pressure is applied from the outside (inside the room) (indicated by arrow F1 in the figure), the surface (D) is compressive (indicated by arrow a) and the opposite surface (C) is tensile (indicated by arrow b). ) Will work. Since this panel has characteristics that it is strong against compressive force and weak against tensile force, when the rib portion is arranged inside, the surface C that receives the tensile force is narrower than the surface D and the force F1 is narrower than the surface C. Therefore, it was used in a weak direction against the force in the direction of arrow b.

This means that, when considering the section modulus of the panel, the section is not used effectively against external force. Thus, in the conventional partition wall,
Since the panel with ribs is installed with the flat surface on the front side (outside) and the ribs on the back side (inside), there is a problem in that it is used in a direction weak in bending strength. Therefore, an object of the present invention is to provide a lightweight fireproof and soundproof partition wall in which the rib portion of the noncombustible panel is arranged outward and has a high bending strength, and excellent soundproofness and fireproofness.

The rib portion 21 constituting the non-combustible material panel 10 may be a hollow product, an L-shaped product, or a T-shaped product in addition to the solid product. Then, the rib portion 21 is arranged outward, that is, toward the indoor side, so that the rib portion 21 serves as a stud. At this time, in order to form the hollow layer 32, a slight space is left between the two noncombustible panels 10. The upper and lower ends of the noncombustible panel 10 are attached and fixed to runners installed on the upper and lower slab surfaces or the beam lower surface. The height of the rib portion 21 in this embodiment is about 45 m.
