Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to prefabricated buildings such as prefabricated sunrooms and prefabricated studies.

BACKGROUND ART Conventionally, structural materials such as columns, beams, and girders for prefabricated buildings have been widely known to be made of aluminum or steel.

However, when aluminum structural members are used, there is a problem in that a building with a floor area of 10 m or more cannot be assembled because aluminum is inferior in strength to steel in terms of building regulations.

In addition, when using steel structural materials, the building assembly method is generally not a prefabricated assembly method, but a method in which the structural materials are cut to predetermined dimensions on site and then connected. Since a long period of time is required, and steel inevitably rusts, there is a problem in that the weather resistance after assembly is insufficient.

Furthermore, prefabricated buildings using aluminum or steel structural members have poorer insulation properties than prefabricated buildings whose structural members are all wood, and if the structural members have exposed indoor surfaces, indoor There has been a problem in that moisture in the air condenses on the surfaces of these metal structural members.

The object of the present invention is to provide an assembled building that solves all of the above problems.

Means for Solving Problems The assembled building according to the present invention is assembled using structural members consisting of a main steel member and wooden sub-members for nailing fixed to the surface of the main member, and is arranged at predetermined locations. The structural material has at least one of an exposed indoor surface and an exposed outdoor surface, and the exposed indoor surface is covered with a wooden interior covering member nailed to the secondary member, and the exposed outdoor surface is covered with a wooden interior covering member nailed to the secondary member. It is characterized in that the surface is covered with an aluminum exterior covering member nailed to the secondary member.

Here, the main members used are those that have been widely used in the past, such as shaped steel and flat steel.

The auxiliary member is for fixing various types of nails such as ordinary nails, screw nails, recessed screw nails, and stables, and is fixed to the surface of the main member with nails, bolts and nuts, adhesives, etc.

The wooden covering member is an interior material for a prefabricated building, and is made of, for example, decorative plywood.

The aluminum covering member is an exterior material for a prefabricated building, and is, for example, an extruded member.

Embodiment Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

In FIGS. 1 and 2, (1) is a structural member of a prefabricated building according to the present invention, more specifically, an eave beam placed under a rafter (2). This structural material (1) consists of a main member (3) made of H-beam steel and two secondary nailing members (4) made of wood that are fixed to the top and bottom walls of the main member (3) with nails, excluding the joints. Become. The secondary member (4) fixed to the upper side wall of the main member (3) has a flat plate shape, and the secondary member (4) fixed to the lower side wall of the main member (3) has a stepped shape.

Such a structural material (1) consisting of two types of members is not one in which the main member (3) and the sub-member (4) are fixed at a construction site, but is manufactured in advance in a factory or the like.

When this structural member (1) is placed at a predetermined position in an assembled building, the structural member (1) has at least one exposed surface of an indoor exposed surface and an outdoor exposed surface. That is, as shown in Figs. 1 and 2, a structural member (1) as an eave girder is placed horizontally under the rafters (2), and a sliding glass door ( 5) A lintel (8) for building
) is placed, the structural member (1) has an exposed indoor surface and an exposed outdoor surface.

The indoor exposed surface of this structural material (1) is
) is covered with an interior covering member (8) made of two pieces of decorative plywood joined in a cross-section shape and nailed to the sub-member (4) of the interior with ordinary nails (7). On the other hand, the outdoor exposed surface is attached to the secondary member (4) of the structural member (1) with screws (9
) is covered with an exterior covering member (lO) made of an extruded aluminum profile with a generally mouth-shaped cross section.

As shown in Fig. 1, the structural members (1) serving as eaves girders are arranged so that the end faces of adjacent ones are butted against each other, and are placed astride the vertical wall where they butt each other, sandwiching the vertical wall from both sides. A steel joint plate (11), a bolt (12) fitted into a hole provided in the vertical wall and the joint plate (11), and a nut (12) screwed into the bolt (12).
3), and joint plates (11) and bolts (
12) and nuts (13) connect adjacent ones.

In FIGS. 3 and 4, the structural member (1) is used as a corner column of the prefabricated building of this invention. This structural member (1) consists of a main member (3) made of cylindrical shaped steel, and two secondary nailing members (4) made of wood that are each fixed to two adjacent side walls with nails. ◎ Two sides of the structural member (1) arranged as a corner pillar, on which the sub-member (4) is located, are each partially covered by a wall panel (14).

The indoor exposed surface of this structural member (1) is an interior covering member ( 8
). On the other hand, the outdoor exposed surface is
An exterior covering member (l) made of an aluminum extruded material with an arcuate cross section is nailed to the secondary member (4) with screws (9).
O).

In FIGS. 3 and 5, structural members (1) are used as studs for prefabricated buildings of the invention. This structural material (
1) consists of a main member (3) made of cylindrical shaped steel and three sub-members (4) made of wood for nailing, which are respectively fixed to the three side walls of the main member (3) with nails. The indoor side exposed surface of the structural member (1) arranged as a stud is made of three decorative plywood sheets nailed to the sub-member (4) with regular nails (7) and joined in a U-shaped cross section. It is covered with an interior covering member (8). On the other hand, its outdoor exposed surface is
) is covered with an exterior covering member (lO) made of a substantially flat aluminum extrusion material and nailed with screws (9).

In Figures 6 and 7, the structural member (1) is arranged as a girder, and its interior exposed surface is an interior covering member (8 ), and its outdoor exposed surface is covered with an exterior covering member (10) made of an extruded aluminum material having a cross-sectional opening shape, respectively, by the same means as described above.

Effects of the Invention The assembly building according to the invention of m; is constructed as described above, and since the main structural members are made of steel, it has sufficient strength, is not regulated by building regulations, and has a floor area of 10M. or more.

In addition, since the assembled building of the present invention is assembled using structural materials consisting of a main steel member and a secondary wooden nailing member fixed to the surface of the main member, the building assembly method is The prefabricated assembly method can be used, and the time required for assembly can be significantly shortened compared to conventional construction methods.

Furthermore, in the assembled building of the present invention, if the structural members arranged at predetermined locations have an exposed outdoor surface, that surface is covered with an aluminum exterior covering member, so that the assembled building has extremely excellent weather resistance after assembly. ing.

Furthermore, since a structural material in which a wooden secondary member is fixed to the main member is used, the secondary member has a large insulation effect. It has extremely high insulation properties compared to conventional prefabricated buildings.

In addition, if the structural material has an exposed surface on the indoor side, that surface is covered with a wooden interior covering member, so in the prefabricated building of the present invention, there is no risk of condensation occurring as in conventional structures. .
