DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a partition wall fixing structure for fixing panel-shaped partition walls to metal ceiling beams and floor beams to which a soft refractory coating material is attached. In particular, the present invention relates to a partition wall fixing structure suitable for a unit building having a fireproof structure.

[0002]

2. Description of the Related Art In recent years, fire-protected areas and quasi-fire-protected areas have been designated, and buildings built in these fire-protected areas and quasi-fire-proof areas are obliged to have good fire-resistance and fire-proof performance like fire-resistant structures and quasi-fire-proof structures. ing. In addition, in a building having three or more floors for use in an apartment house, a hospital, a hotel, and the like, the building standard law stipulates that a fireproof structure having a predetermined fireproof performance be provided.

[0003] Buildings with this fireproof structure must pass a fireproof test specified in JIS, except for structures specified by the Building Standards Law. In order to pass this fire resistance test, steel columns are usually made of steel to prevent the steel structural materials such as columns and beams from becoming hot and reducing their mechanical strength when heated under specified temperature conditions. Structural materials such as beams and beams are covered with a fireproof covering material.

[0004] In many buildings having such a fire-resistant structure that satisfies certain conditions, it is specified that a partition wall having good fire resistance is provided. For example, it is necessary to provide a fire-resistant structure for a partition wall that partitions a fire prevention partition, a partition wall of an apartment house, a partition wall of a school, a hospital, or the like. And
As means for providing the partition wall, a partition wall made of reinforced concrete, a plate such as an extruded cement plate, an extruded calcium silicate plate, an ALC plate (autoclave lightweight concrete plate), or a PC plate (precast concrete plate) is used. In many cases, a partition wall is attached.

On the other hand, a building unit, a roof unit, and a roof panel obtained by dividing a building into a transportable size are manufactured in a factory, and the building unit, the roof unit, and the roof panel are transported to a construction site, and assembled at the construction site. Unit buildings are often used because they have a short on-site construction period and high accuracy. Also known as this unit building is a building having a fireproof structure in which a fireproof covering material is attached to structural materials such as columns, ceiling beams, floor beams, and the like.

[0006] For example, Japanese Patent Application Laid-Open No. 8-74348 describes a building having such a fireproof structure. That is, the floor structure of this building is such that a member is attached to a metal floor beam having a substantially U-shaped cross section, a floor base material is attached to the member, and a floor joist is attached on the floor base material. A floor material is attached on the floor joist, and the side and upper surfaces of the floor beam are covered with a soft fire-resistant coating material, and both sides of the soft fire-resistant coating material are in contact with the upper surface of the floor base material. Then, attach a soft refractory coating. Also, the ceiling structure of this building is
A member is attached to a metal ceiling beam having a substantially U-shaped cross section, a bracket is attached to the member, and a ceiling surface material is attached to the bracket through a through member. The soft refractory covering material is attached so that the side and lower surfaces of the ceiling beam are covered with the soft refractory covering material that has passed through, and both sides of the soft refractory covering material are in contact with the lower surface of the floor base material.

[0007] In this manner, the ceiling beam and the floor beam are surrounded by the soft refractory coating material and the floor base material to prevent the ceiling beam and the floor beam from having high-temperature performance in a fire. Then, a soft refractory coating material is pressed from above between the floor beams of the adjacent building units, and is made substantially flush with the floor surface material, and a joint floor surface material is attached. The fireproof covering material is pressed from below to make it substantially flush with the ceiling surface material, and the joint ceiling surface material is attached.

When a wall such as a partition wall is provided between the floor beam and the ceiling beam, a wall panel is attached and fixed between the joint floor surface material and the joint ceiling surface material to form a wall. As described above, in this unit building, the wall panels such as the partition walls are fixed to the joint floor panel and the joint ceiling panel, and are not directly fixed to the floor beam or the ceiling beam.

[0009]

However, in the case of a partition wall provided in a single house, a wall panel is fixed to a joint floor or joint ceiling such as wood or gypsum board. However, in the case of a partition wall provided in a building having a fire-resistant structure, it is necessary to separate the floor beam from the ceiling beam with a noncombustible material. Therefore, such a wall fixing structure cannot be adopted.

[0010] In the unit building, a unit floor manufactured at a factory is transported to a construction site, and a plurality of unit buildings are installed at the construction site to form a building. The face material and joint ceiling face material cannot be attached. Therefore, the wall panels to be attached to the joint floor material and the joint ceiling surface material must be installed on site, which increases the number of on-site construction man-hours and reduces the characteristics of unit buildings that require less on-site construction man-hours. There's a problem.

Further, if nails or screws are used to fix the joint floor material or the joint ceiling material, the soft refractory material may be damaged. In view of the above, an object of the present invention is to solve the above-described problems, and to install a partition wall or the like on a ceiling beam or a floor beam to which a soft refractory covering material is attached. It is an object of the present invention to provide a partition wall fixing structure which can be fixed by using the above.

[0012]

SUMMARY OF THE INVENTION The present invention has been made to achieve the above-mentioned object, and a panel-shaped partition wall is inserted between a metal ceiling beam and a floor beam to which a soft refractory coating material is attached.

The partition wall in the present invention is a panel formed of a plate having good fire resistance, and is a non-combustible plate such as an extruded cement plate, an extruded calcium silicate plate, an ALC plate or a PC plate. Is preferably in the form of a panel. In particular, a panel formed from an extruded cement board is preferable. Further, if the beam fixing portion of the under-beam support or the upper beam support used in the present invention is provided with an extension that extends longer in the longitudinal direction of the ceiling beam or the floor beam than the member fixing portion, this extension is used. When attaching to a ceiling beam or a floor beam, the member fixing portion is convenient without being in the way.

[0014] Further, if the member fixing portion of the under beam support or the upper beam support is provided with a protruding portion that protrudes long in the width direction of the ceiling beam or the floor beam, it can be provided from just below the ceiling beam or the floor beam. This is convenient because a partition wall can be provided at a location where the projection has moved only. Further, if the first piece of the floor receiving rail is made longer, the second piece can be provided at a different position as long as the length of the floor beam, which is convenient.

The soft refractory coating material used in the present invention is a coating material which is bendable and has excellent fire resistance and is made by processing a ceramic fiber such as rock wool or zircon fiber into a felt shape or water. There is a heat-absorbing pack in which the balloon or water contained is gelled by a high heat-absorbing polymer is put in this felt shape or wrapped with a cloth with aluminum foil. In particular, it is preferable that an endothermic pack in which water is gelled with a high endothermic polymer and a ceramic felt having a heat resistance temperature of 1000 ° C. or more are wrapped with a cloth with aluminum foil.

(Function) In the present invention, the beam fixing portion of the under-beam support is attached to the ceiling beam, and the web of the ceiling receiving rail is attached to the member fixing portion of the under-beam support. The rail is firmly attached to the ceiling beam via a beam support. Also, since the beam fixing portion of the beam receiving bracket is attached to the floor beam, and the first piece of the floor receiving rail is attached to the member fixing portion of the beam receiving bracket, the floor receiving rail is attached to the floor beam. It is firmly attached via the upper bracket.

Since the partition wall is fixed to the ceiling receiving rail and the floor receiving rail, the partition wall is firmly attached to and fixed to the ceiling beam via the ceiling receiving rail and the under beam fitting. Also, it is firmly attached and fixed to the floor beam via the floor receiving rail and the beam-on metal fitting. Further, since the partition wall is fixed to the ceiling beam and the floor beam in this way, the partition wall can be attached to the building unit regardless of the adjacent building unit. Therefore, the partition wall can be attached to the building unit in a factory or the like, and the number of man-hours at the construction site can be eliminated.

Further, since the partition wall is attached to the floor beam or the ceiling beam via the metal lower support, the upper support, the ceiling support rail, and the floor support rail, the partition wall and its support can be used in the event of a fire. The function of the partition wall can be sufficiently performed without spreading the fire to the opposite side through the upper and lower portions. In the present invention, the under-beam receiving member has a substantially parallel beam fixing portion and a member fixing portion separated by a distance substantially equal to the thickness of the soft refractory coating material, and a connecting portion connecting the beam fixing portion and the member fixing portion. An opening formed by a beam fixing part, a member fixing part, and a connecting part of the beam ceiling fitting is provided between the partition wall attached to the ceiling receiving rail and the ceiling beam because the metal piece is a substantially E-shaped metal piece made of Is a covering material storage portion, a gap having a distance substantially equal to that of the covering material storage portion is formed.

The beam-on-metal fitting comprises a substantially parallel beam fixing portion and a member fixing portion separated by a distance substantially equal to the thickness of the soft refractory coating material, and a connecting portion connecting the beam fixing portion and the member fixing portion. Since it is a substantially E-shaped metal piece comprising: a beam fixing portion, a member fixing portion, and a connecting portion of the beam-on metal fitting are provided between the partition wall attached to the floor receiving rail and the floor beam. Assuming that the opening to be formed is a coating material storage portion, a gap having a distance substantially equal to that of the coating material storage portion is formed. Therefore, the soft refractory coating can be attached without using nails, screws, etc. by mounting the soft refractory coating through the gaps between the coating storage section and the ceiling beams and floor beams, and the soft refractory coating is damaged. There is no concern about this, and the attached soft refractory coating material is locked by the member fixing portion and does not come off.

The partition wall is provided with an upper cutout on both sides at the upper end, and a lower cutout on one side at the lower end, and the partition wall is provided on both sides at the upper end. The flanges on both sides of the ceiling receiving rail are inserted into the notch, and the second piece of the floor receiving rail is inserted into the lower notch provided on one side of the lower end, and is fixed to the ceiling receiving rail and the floor receiving rail. Therefore, the ceiling support rail is attached to the ceiling beam in advance via the under-beam support, and the floor support rail is installed to the floor beam via the beam support in advance, and the upper end of the partition wall is attached to both sides of the ceiling support rail. The lower end of the partition wall is pressed against the second piece of the floor receiving rail, the upper end is fixed to the floor receiving rail, and the upper end is fixed to the floor receiving rail. Can be easily installed.

Since the upper notch is large enough to receive the flange of the ceiling receiving rail, the flange of the ceiling receiving rail fits completely into the upper notch, and the lower notch is substantially the same as the floor receiving rail. Since the L-shaped second piece is large enough to fit, the second piece of the floor receiving rail fits completely into the lower cutout, and the ceiling receiving rail and the floor receiving rail do not protrude from the surface of the partition wall. Therefore, when attaching a wall base material such as a calcium silicate plate or a gypsum board to be attached to the partition wall, or a wall finishing material such as a decorative sheet, a wallpaper, or a decorative calcium silicate plate, the ceiling receiving rail and the floor receiving rail do not interfere. In addition, the wall base material and the wall finishing material can be attached beautifully without this portion protruding.
