While sinking into the concrete panel, it rotated around the thin base material, and this rotation determined the horizontal strength and rigidity of the screw mounting part. Therefore, in order to improve the horizontal strength and rigidity of the screw mounting portion, it is necessary to improve the rotation resistance around the thin base material, which is the screw mounting member.

して用いることもできる。[0007] The mounting member used in the present invention is a precast lightweight concrete panel fixed with a metal fitting (for example, a screw).
It is intended to be attached to the building via a, and while fixing the precast lightweight concrete panel in the out-of-plane direction, against external force in the direction orthogonal to the axial direction of the fixing bracket,
This is for restraining the fixing bracket from penetrating the mounting member so that rotation in the direction of external force does not occur. The mounting member is made of a solid or hollow metal having a thickness of 6 mm or more, or a plastic having a thickness equivalent to that of the metal, and generally uses a dedicated mounting member fixed to a column, a beam, or the like. However, steel-frame columns and beams themselves can be used as attachment members.

ことが好ましい。As the dedicated mounting member, a steel plate having a thickness of 6 mm or more may be used, but a thin steel plate having a thickness of about 1 to 3 mm processed into a rectangular pipe shape or the like is often used. When a thin steel plate having a thickness of about 1 to 3 mm is used, it is not always necessary to use a rectangular pipe, and the two opposing surfaces through which the fixing bracket penetrates have an outer dimension of 6 mm or more and have an in-plane direction. Any structure may be used as long as it is arranged so as not to cause displacement. When fire resistance is not required, a dedicated mounting member made of plastic can be used. In that case, it is preferable to use hard plastic.

ものになる。[0009] When a steel column-and-column itself is used as a mounting member, a square steel pipe, a round steel pipe, an H-shaped steel or the like is generally used as a column, and an H-shaped steel is generally used as a beam. Depending on the thickness of the mounting member, rotation of the screw around the mounting member due to external force in a direction perpendicular to the axial direction of the screw is less likely to occur, but the outside diameter of commercially available screws is 6 mm or less. Considering this, if the thickness of the mounting member is not less than the outer diameter of the screw, that is, not less than 6 mm, the rotation about the mounting member due to the external force in the direction perpendicular to the axial direction of the screw becomes extremely small. Further, when the thickness of the mounting member is equal to or larger than the outer diameter of the screw, the effect obtained by increasing the thickness is reduced.

ンクリートパネルを安定させることが好ましい。The fixing bracket used in the present invention is used for fixing a precast lightweight concrete panel to a mounting member in an out-of-plane direction (axial direction of the fixing bracket) and in an in-plane direction. Although a bolt or the like can be used, a screw having a diameter of about 5 to 6 mm is particularly often used. As a method of attaching the fixing bracket, for example, a screw can be driven substantially perpendicularly from the surface of the precast lightweight concrete panel to the surface of the attachment member that is in contact with the back surface of the precast lightweight concrete panel. Also, in some cases, mounting members are placed on the surface of the precast lightweight concrete panel,
It is also possible to drive screws from the mounting member side,
In this case, a support material for the precast lightweight concrete panel is provided on the back surface of the precast lightweight concrete panel, and the precast lightweight concrete panel is stabilized against a driving load when driving a screw, an external force applied after the screw is applied, and the like. Is preferred.

るのが好ましい。When a screw is used, it is preferable to use a self-drilling screw, which does not require the preparation of a pilot hole, because the workability is good. In particular, when a self-drilling screw is driven into a hollow steel mounting member, the self-drilling screw drills and drives two steel plate members. When drilling the first steel plate when the second steel plate is drilled, if the thread is applied to the first steel plate, the progress speed of the drill part of the screw and the progress speed of the screw part of the screw are different, so a large resistance occurs, Construction is difficult. Therefore, in this case, the drill portion should be longer than the outer dimensions of the two opposing surfaces of the hollow steel mounting member, or the first plate material should be drilled when the second steel plate is being drilled. It is preferable to use a special screw that has been partially removed from the screw so that the screw thread is not applied to the screw.

どの構造材料を省略することもできる。[0012] The mounting structure of the precast lightweight concrete panel configured as described above is used to fix the precast lightweight concrete panel when an external force in the in-plane direction (the direction orthogonal to the axial direction of the screw) is transmitted to the precast lightweight concrete panel through the fixture. Since the metal fitting is constrained so as not to rotate in the direction of the external force at the portion where the metal fitting penetrates the mounting member, the external force transmitted to the light-weight precast concrete panel through the fixing metal is equal to the thickness of the light-weight precast concrete panel. Since the precast lightweight concrete panel is transmitted in a wide range in the direction, the precast lightweight concrete panel is less susceptible to damage such as depression and cracking due to external force transmitted through screws. Accordingly, when the precast lightweight concrete panel according to the mounting structure of the present invention is used for a slab surface such as a wall surface, a floor, or a roof of a building, the precast lightweight concrete panel is less likely to be damaged by an external force in an in-plane direction, and Excellent in proof stress and rigidity. In addition, the precast lightweight concrete panels used on the walls and slab surface can sufficiently bear the in-plane external forces such as seismic force applied to the building through the mounting members and fixing brackets. The deformation of the surface due to external force can be prevented, and the earthquake resistance can be improved. In addition, if the effect of the precast lightweight concrete panel is appropriately taken into consideration, the structural materials such as fire, bracing, and bracing of the building can be omitted.

In the present invention, since a ductile material such as metal or plastic is used for the mounting member, the mounting portion structure also has ductile properties, and is excellent in proof strength and rigidity against repeated loads. Also, the ALC of the mounting part
Even if the panel is partially damaged, the strength of the mounting portion does not decrease sharply, so that the mounting portion has a tenacious structure.

It is stuck. The mounting base material 5 is previously fixed to the steel horizontal member 2 at a factory in a state where the 270 mm wide flat plate and the U-shaped member are integrated. The welding between the mounting base material 5 and the steel horizontal member 2 is performed by spot welding using a staggered hole at a pitch of about 200 mm on the flat plate portion of the mounting base material 5. The mounting base material 5 is not limited to the above-described configuration, and the flat plate portion and the U-shaped portion may be integrally formed by bending, or a U-shaped mounting base as shown in FIG.

ない。According to the present invention, when the precast lightweight concrete panel attached to the mounting member using the fixing bracket receives a force orthogonal to the axial direction of the fixing bracket, the mounting member is attached to the fixing bracket. Since rotation around the center is unlikely to occur, and stress generated between the fixture and the precast lightweight concrete panel is distributed over a wide range in the thickness direction of the precast lightweight concrete panel, the mounting portion is excellent in strength and rigidity. In addition, since the ductile material restrains the rotation of the fixture due to a force orthogonal to the axial direction of the fixture, the mounting structure of the present invention has ductile properties and is excellent in proof strength and rigidity against repeated loads. Further, even if the precast lightweight concrete panel of the mounting portion is partially damaged, a sharp decrease in strength and rigidity does not occur.
