BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a partition wall according to a first embodiment of the present invention; FIG.

[First Embodiment] First, an example in which a corrugated wire mesh is used as a reinforcing wire mesh of a wall panel constituting a partition wall will be described.

As shown in FIG. 1, for example, a partition wall 1 applied to, for example, a doorway of an apartment house has the same basic structure as that of a conventional one, and steel studs (studs; not shown) are provided at predetermined intervals. A pair of wall panels 2 erected each to form a wall surface
Are provided on both sides of these studs, and a sound absorbing material (not shown) such as rock wool or glass wool is filled between the wall panels 2 and 2.

On both sides of the partition 1, a wall panel 2
Are installed in the direction in which the partition walls 1 are continuous.

Each of the wall panels 2 includes a panel main body 3 formed of an ultralight cement hardened body containing an ultralight aggregate,
It is roughly constituted by a reinforcing wire mesh 4 buried in the entire panel body 3.

The panel body 3 is made of an ultralight cement hardened material containing an ultralight aggregate. For example, the configuration of Japanese Patent Application No. 61-79521 previously disclosed by the present applicant is used. As shown in FIG. 2, a large number of concave portions 5, 5,...

As shown in FIG. 3, the reinforcing wire mesh 4 is formed by combining vertical bars 6, 7 and a horizontal bar 8,
In this, a predetermined prestress is introduced in the vertical direction. The vertical streaks 6 are arranged so as to extend in the vertical direction on one surface side of the panel main body 3, and the other vertical streaks 7 are arranged so as to extend in the vertical direction on the other surface side of the panel main body 3. ing. The vertical stripes 6 and 7 have a configuration in which the vertical stripes 6 and the vertical stripes 7 are alternately arranged in the horizontal direction along the surface of the panel body 3. Further, the horizontal streaks 8 are formed to be bent at the portions in contact with the vertical streaks 6, 7, thereby being configured to be alternately joined to the vertical streaks 6, 7. In this manner, the reinforcing wire mesh 4 has a configuration having a waveform as a whole and having a high tension.

As shown in FIG. 4, on both sides of the reinforcing wire mesh 4, reinforcing force distribution wires, flat mesh wires, crack preventing wire mesh 9 and the like are appropriately selected and combined, and are arranged. Buried inside.

On both side surfaces of the wall panel 2, connection fittings 10 and 11 for connecting the wall panel 2 to another wall panel 2 are buried with their surfaces exposed. These fittings 1
Reference numerals 0 and 11 are formed of a punching metal having a large number of holes over the entire surface. As shown in FIGS. 4 and 5, one connection fitting 10 is formed with a groove (recess) 12 that is vertically continuous. On the other connection fitting 11, a ridge (projection) 13 having a shape corresponding to the groove 12 is formed. These grooves 12 and ridges 13
Has a tapered cross-sectional view in which the width gradually decreases toward the bottom of the ridge and the tip of the ridge 13.

As shown in FIG. 4, the wall panels 2 and 2 provided with such connection fittings 10 and 11 are connected by fitting the groove 12 of the connection fitting 10 and the ridge 13 of the connection fitting 11. It is supposed to. At this time, since the groove 12 and the ridge 13 are tapered in cross section, the fitting operation can be performed easily and reliably.

In order to manufacture the wall panel 2 constituting the partition wall 1, for example, a mold 15 as shown in FIG. 6 is used. The formwork 15 is a laminated type in which a plurality of wall panels 2 can be formed at the same time, and a formwork plate 17 having a convex surface 16 for forming the concave portion 5 on the lower surface and a smooth upper surface.
have.

When the wall panel 2 is manufactured, the connection fittings 10 and 11 are set at predetermined positions of the formwork 15.
After setting the reinforcing wire mesh 4, an ultralight cement hardened body is cast into the mold 15. At this time, as shown in FIG. 7, if both ends of the reinforcing wire mesh 4 are pulled by jacks or the like and the jacks or the like are released after the ultralight cement hardened material is cured, a predetermined prestress is applied to the reinforcing wire mesh 4. It will be in the introduced state.

In the partition wall 1 described above, a panel main body 3 formed of an ultralight cement hardened body and a panel main body 3
Is formed by a wall panel 2 composed of a reinforcing wire mesh 4 into which a prestress has been introduced with a corrugation buried so as to cover almost the entire surface. As described above, since the wall panel 2 is configured to have the reinforcing wire mesh 4, it can be made into a thin, flat plate without ribs and having sufficient strength. As a result, the wall thickness of the partition wall 1 can be reduced, and the transportation cost can be reduced since the partition wall 1 is not bulky during transportation. In addition, since the weight of the wall panel 2 can be reduced, construction can be performed efficiently and cost can be reduced. Of course, since the wall panel 2 is made of cement, even if it is wet with rainwater or the like, mold does not grow and high quality can be maintained.

Further, metal connecting fittings 10 and 11 are provided on both side surfaces of each wall panel 2, a groove 12 is formed in one connecting fitting 10, and a ridge 13 is formed in the other connecting fitting 11. It has a configuration. Thus, the wall panel 2
In the connection portion between the two, the groove 12 of the connection fitting 10 of one wall panel 2 is inserted into the groove 12 of the connection fitting 11 of the other wall panel 3.
By fitting this, it is possible to make this connecting portion a so-called tenon connection that is effective for improving fire resistance and sound insulation performance. At this time, the connecting fittings 10 and 11 can prevent the ridge 13 from breaking even when the wall panel 2 is made thinner.

In addition, since the connection fittings 10 and 11 are formed of a punched metal having a large number of holes, the adhesion to the panel body 3 can be ensured.

The panel body 3 has a structure in which a large number of recesses 5 are formed. Thereby, the sound insulation performance of the partition wall 1 can be improved.

Further, when manufacturing the wall panel 2,
Since the laminated type frame 15 is used, a plurality of wall panels 2 can be simultaneously manufactured in a small space, thereby reducing labor and reducing the manufacturing cost of the wall panels 2. Becomes possible.

In the first embodiment, the prestress is introduced into the corrugated reinforcing wire mesh 4, but if the required strength can be obtained only by the reinforcing wire mesh 4, the prestress is introduced. It is also possible to adopt a configuration that does not. Further, as long as the reinforcing wire mesh 4 has a waveform as a whole, the shape and the like of the horizontal streaks 8 are not limited to those described above.

[Second Embodiment] Next, a description will be given using an example in which, for example, a normal flat wire mesh is used as a reinforcing wire mesh of a wall panel constituting a partition wall, and this is a double reinforcing bar. I do. In the following description, the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

As shown in FIG. 8, similar to the partition wall 1 (see FIG. 1), the partition wall 21 has steel studs (studs; not shown) erected at predetermined intervals to form a wall surface 2.
A pair of wall panels 22 are provided on both sides of these studs, and a sound absorbing material (not shown) such as rock wool or glass wool is filled between the wall panels 22, 22.

The wall panel 22 includes a panel body 3 and two reinforcing wire meshes 24, 24 embedded in the panel body 3.
And connecting fittings 10 and 11 provided on both side surfaces thereof (FIG. 4).
Reference). The reinforcing wire mesh 24, 24
The wall panels 22 are arranged at predetermined intervals in the thickness direction. Each reinforcing wire mesh 24 is a normal flat type, in which vertical streaks 25 and horizontal streaks 26 arranged in the same plane are assembled in a lattice shape, and a predetermined prestress is introduced vertically. ing.

To manufacture such a wall panel 22,
The connection fittings 10 and 1 are placed at predetermined positions on the mold 15 shown in FIG.
1 is set, and the reinforcing wire meshes 24 are set at predetermined intervals. If both ends of the reinforcing wire meshes 24, 24 are pulled by jacks or the like, an ultralight cement hardened body is cast, and the jacks or the like are released after hardening, a predetermined prestress is introduced into the reinforcing wire meshes 24. State.

The same effect as that of the partition wall 1 shown in the first embodiment can also be obtained with the above-described partition wall 21. Such a flat reinforcing wire mesh 24, 24
Is particularly suitable for use, for example, for those having a height of about 2.5 m or less.

In the first and second embodiments, the components and the like of the ultra-lightweight hardened concrete body forming the panel body 3 are not limited at all. Further, as for the connection fittings 10 and 11 provided on the wall panels 2 and 22, the material, the cross-sectional shape and the like may be other than those described above. Further, the mold 15 for producing the wall panels 2 and 22 may be of a type other than the laminated type.

This is a configuration formed by wall panels. According to the partition wall of the second aspect, the reinforcing wire mesh is arranged on one side of the panel main body, the vertical streaks arranged on the other side, and the vertical streaks on one side and the other side. It has a configuration consisting of a horizontal streak bent and arranged so as to be alternately connected to a vertical streak. Further, according to the partition wall of the third aspect, a prestress is introduced into the reinforcing wire mesh. Since the wall panel has the reinforcing wire mesh as described above, the wall panel can have a sufficient strength even if it is a thin-walled, flat plate having no ribs. The wall thickness of the wall can be reduced, and it is not bulky during transportation, so that transportation costs can be reduced. Further, since the weight of the wall panel can be reduced, the construction can be performed efficiently and the cost can be reduced. Of course, because the wall panels are cement-based,
High quality can be maintained without generating mold even when wet with rainwater or the like.

According to the partition wall of the fourth aspect, metal connecting fittings are provided on both side surfaces of each wall panel, and the connecting fitting on one side is formed with a recess extending in the vertical direction, and the other side is provided with a concave part. Are formed with convex portions. In this way, when the connecting portion between the wall panels is a so-called tenon connection that is effective for improving fire resistance and sound insulation performance,
By arranging a connection fitting in this connection, even when the wall panel is made thinner, it is possible to prevent the projection from breaking.
