The lath net 2 is arranged on the outer surface 1c of the one synthetic resin foam concrete formwork 1a facing to the above, and the lath net 2 is attached to the separator 3 and the concrete 5 by the staples 6a, 6b with return. By being locked, it is prevented from floating on the outer surface 1c of the one synthetic resin foam concrete formwork 1a.

The term "floating stopper" as used herein means
The lath net 2 refers to a state in which the lath net 2 is locked without being embedded on the outer side surface 1c of one synthetic resin foam concrete formwork 1a, and the protruding portion of one side of the lath net 2 is a synthetic resin foam. In addition to the case where the concrete formwork 1a is brought into contact with the outer side surface 1c and is locked in a floating state as a whole, another space is provided between the lath net 2 and the outer side surface 1c of the synthetic resin foam concrete formwork 1a. The case where the member is locked in a state where the gap is formed is also included.

Next, this embodiment will be described in order. As shown in FIG. 1, first, the two synthetic resin foam concrete forms 1a and 1b are arranged with a predetermined interval by a separator 3 and are arranged at predetermined positions of the structure A so as to face each other. In this case, these two synthetic resin foam concrete forms 1a and 1b are joined so as to be stacked in the vertical direction as necessary, and a lattice-shaped reinforcing bar B or the like is pre-arranged in the inside 4 thereof. .

It is possible to use those having a predetermined strength with a size of about m (sub-block), and when they are arranged as described above, they may be joined to each other so as to be arranged in the lateral direction.

As shown in FIGS. 2 and 3, the separator 3 is, for example, a separator body 3 formed in a grid pattern.
and a rib 3b integrally formed in the both ends of the separator body 3a at right angles. The two ends of the separator 3 are connected to the two synthetic resin foam concrete molds 1a, 1b.
These two synthetic resin foam concrete forms 1a and 1b are opposed to each other and are spaced apart from each other by a predetermined distance. As shown in FIG. 3, the distance L from the outer side surface 1c of the synthetic resin foam concrete formwork 1a to the rib 3b and the inner side surface 1d of the synthetic resin foam concrete formwork 1b to the rib 3b is ,
Although not particularly limited, the shorter L is, the more the pressure resistance of the cast concrete 5 is improved, and further, the staples 6a and 6b (locking tools) with return can be locked even if they are short.

After the two synthetic resin foam concrete forms 1a and 1b have been spaced by the separator 3 as described above, as shown in FIGS. 4 and 5, these two synthetic resin foams are formed. Concrete formwork 1a, 1b
Concrete 5 is poured into the inside 4 of the.

Thereafter, as shown in FIGS. 6 and 7, a lath net 2 is arranged on the outer surface 1c of the synthetic resin foam concrete formwork 1a facing the outside of the structure A, and the lath net 2 is formed. , For example, two types of staples with return 6a,
By locking the separator 3 and the concrete 5 by 6b, the synthetic resin foam concrete frame 1a is prevented from floating on the outer surface 1c.

The staple with return 6b (6a) is
As shown in FIG. 8, returns 6d are provided on both sides of a U-shaped body 6c having a sharp tip, and the U-shaped body 6c is formed by changing the length thereof. And the return 6

Here, as shown in FIG. 6, of the two returnable staples 6a and 6b, the shorter returnable staple 6a penetrates the rib 3b of the separator 3 and the longer returnable staple 6a. The tip 6e of the staple 6b may be driven so as to be embedded in the concrete 5.

The longer staple 6 with a return member
If the b is driven in a state where the concrete 5 is not solidified, the staple with return 6b can be easily driven. Also, this longer staple 6b with return
May be used to prevent the separator 3 from floating. Further, in this embodiment, the lath net 2 is locked to both the separator 3 and the concrete 5, but the present invention is not limited to this, and at least one of the separator 3 and the concrete 5 is provided. It may be locked only.

The lath net 2 is not limited to the flat lath as in this embodiment, but may be a metal lath such as a hump lath, a corrugated lath or a rib lath, a rhombus lath, an instep lath or a round lath. Various types of wire laths such as shaped laths, welded wire netting or punching metal, composite lath nets in which a plurality of lath nets are stacked and fixed by welding, lath bodies in which lath nets are reinforced by appropriate reinforcing members, etc. Can be used. Further, it is desirable that the lath net 2 be subjected to rust prevention treatment or waterproof treatment in advance or after being suspended from the outer surface 1c of the synthetic resin foam concrete formwork 1a, and in this case, for example, A tar material such as coal tar, an adhesive, a resin material or the like may be applied or coated. Further, as shown in FIG. 7, if the lath net 2 is formed in a long size so that it can be arranged over a plurality of the synthetic resin foam concrete forms 1a,
Mutual connection becomes stronger.

Further, as shown in FIG. 9, the separator 3 is formed by the return staples 6a and 6b as described above.
Mortar or concrete 7 or the like is applied from the surface of the lath net 2 which is retained on the outer surface 1c of the one synthetic resin foam concrete formwork 1a by being locked to the concrete 5 or the concrete 5. . In this state,
The lath net 2 can improve the adhesion of the mortar or concrete 7 or the like.

In this embodiment, the lath net 2 is connected to the outer surface 1 of the synthetic resin foam concrete formwork 1a.
However, the present invention is not limited to this. For example, a plurality of convex portions are provided on the lath net 2 and these convex portions are combined with the synthetic resin foam concrete. These lath nets 2 are locked to the formwork 1a, or a plurality of convex parts are provided on the outer surface 1c of the synthetic resin foam concrete formwork 1a and the lath net 2 is locked to these convex parts. If a gap is formed between and the outer surface 1c of the synthetic resin foam concrete formwork 1a, the mortar 7 is inserted into the gap and solidifies so as to embrace the lath net 2 and thus is difficult to peel off. Moreover, the mortar or the like 7 can be formed thick and the strength of the structure A can be further improved.

If the construction is performed as described above, the concrete formwork 1 can be applied to both sides of the concrete 5 foundation or wall.
a and 1b can be joined as they are without being removed, and at least one concrete formwork 1a facing the outside of the structure A can be a heat insulating foundation or a heat insulating wall made of synthetic resin foam. it can. Therefore, at least one of the synthetic resin foam concrete forms 1a exerts heat insulating properties, and the heat retaining property of the underfloor space or the indoor space can be improved. Further, since it is not necessary to remove the concrete forms 1a and 1b, it is possible to improve workability.

Furthermore, since the lath net 2 is locked to at least one of the separator 3 and the concrete 5 by a locking tool such as staples 6a and 6b with a return member, it is difficult to remove the locking tool, and thus the lath The net 2 can be firmly locked by the outer surface 1c of the synthetic resin foam concrete mold 1a. Here, when the locking tool is locked to the concrete 5, the locking tool can be driven in a state where the concrete 5 is not solidified, so that there is an advantage that the work is simple. When the mortar or the like 7 is applied from the surface of the lath net 2, the mortar or the like 7 bites into the mesh of the lath net 2, so that the adhesive force can be improved.

If the separator 3 is made of plastic as in this embodiment, it is softer than metal or the like, so that the fasteners such as the staples 6a and 6b with the return members penetrate the separator 3. It has the advantage that it can be used for a long period of time because it can be driven while being driven and has excellent corrosion resistance and weather resistance. Further, it has an advantage that the thermal conductivity is lower than that of the metallic one, and the heat insulating effect is further improved.

As shown in FIGS. 10 and 11, the method of attaching the lath net 2 to the synthetic resin foam concrete formwork 1a according to the second embodiment is almost the same as that of the first embodiment, and One synthetic resin foam concrete formwork 1a,
Before pouring concrete 5 into the interior 4 of 1b, the lath net 2 is suspended.

That is, in the same manner as above, the two synthetic resin foam concrete forms 1a and 1b are connected to the separator 3
After a predetermined interval is provided by the above, a lath net 2 is arranged on the outer surface 1c of the synthetic resin foam concrete formwork 1a, and the lath net 2 is combined with the separator 3 and one of the ones by returning staples 6a and 6b. The synthetic resin foam concrete formwork 1a is locked on the outer surface 1c of the synthetic resin foam concrete formwork 1a, and then the two synthetic resin foam concrete formwork 1a,
Concrete 5 is poured into the inside 4 of 1b.

Here, when the lath net 2 is locked to the synthetic resin foam concrete formwork 1a, the tip 6e of the staple 6b with a return is made into contact with the two concrete formwork 1a.
Since the synthetic resin foam concrete formwork 1a is driven into the inside 4 of the a and 1b so as to project from the inner side surface 1e thereof, when the concrete 5 is subsequently placed, the staples 6b with return members 6a are provided. The tip 6e of the is embedded in the concrete 5 and becomes harder to come off after solidification.

As shown in FIGS. 12 and 13, the method for attaching the lath net 2 to the synthetic resin foam concrete formwork 1a according to the third embodiment is substantially the same as that in the second embodiment. The staple 6a with the return is used as a retainer for retaining the mesh 2 on one of the synthetic resin foam concrete molds 1a, and the tip 6e of the staple 6a with the return is used.
Is to project into the concave portion 1f formed on the inner side surface 1e of the synthetic resin foam concrete mold 1a.

Then, as shown in FIG. 13, concrete 5 is applied to the inside 4 of the two concrete forms 1a and 1b.
Then, the concrete 5 is also placed in the recess 1f, and the tip 6e of the staple 6a with return is embedded.

In this way, the tip 6e of the locking device such as the staple 6a with a return is made to project only into the recess 1f so as not to project from the inner surface 1e of the synthetic resin foam concrete formwork 1a. In this case, the synthetic resin foam concrete formwork 1a and the like can be transported compactly even if the lath net 2 is attached in advance by a locking tool in a production plant or the like. Also, because of that,
There is an advantage that it is possible to mass-produce the synthetic resin foam concrete formwork 1a and the like in which the lath net 2 is attached by a locking tool in advance.

As shown in FIG. 14, the method of attaching the lath net 2 to the synthetic resin foam concrete formwork 1a according to the fourth embodiment is the same as that of the third embodiment. A filling material is filled, and the leading end 6e of the staple 6a with a return is embedded by the filling material.

As described above, the staple 6a with the return is provided.
By embedding the tip 6e of the locking tool such as, there is an advantage that the locking tool is not likely to come off during transportation.

Then, similarly to the above, if concrete 5 is cast into the inside 4 of the two synthetic resin foam concrete forms 1a and 1b, and mortar 7 is applied from the surface of the lath net 2, The cast concrete 5 and the mortar 17 filled in the recess 1f react with each other and become substantially uniform, resulting in the state shown in FIG.

As shown in FIGS. 15 and 16, the method of attaching the lath net 2 to the synthetic resin foam concrete formwork 1a according to the fifth embodiment is almost the same as that of the first embodiment, and the above-mentioned return Instead of the attached staples 6a and 6b, the lath net 2 is partially adhered to the outer side surface 1c of the one synthetic resin foam concrete formwork 1a with an adhesive 8 so as to be prevented from floating.

The lath net 2 is partially adhered to c by the adhesive 8. In this case, the adhesive 8 may be applied to the lath net 2 in advance. The adhesive 8 may be, for example, an epoxy adhesive or the like.

Then, as shown in FIG. 16, mortar or concrete 7 is applied from the surface of the lath net 2 in the same manner as above.

As shown in FIG. 17, the method of attaching the lath net 2 to the synthetic resin foam concrete formwork 1a according to the sixth embodiment is the same as the method for attaching the concrete 5 in the fifth embodiment. The lath net 2 is partially adhered to the outer surface 1c of the synthetic resin foam concrete formwork 1a by an adhesive 8 so that the lath net 2 is prevented from floating.

As described above, if the lath net 2 is suspended in advance, the synthetic resin foam concrete formwork 1
There is an advantage that the strength of “a” is improved and, accordingly, the strength of “a” becomes stronger against an impact when the concrete 5 is placed.

As shown in FIGS. 18 and 19, the method of attaching the lath net 2 to the synthetic resin foam concrete formwork 1a according to the seventh embodiment is the same as the lath net 2 in the fifth embodiment. After being partially adhered by the adhesive agent 8, the staples 6a and 6b (retaining members) with a return mechanism are engaged with the separator 3 and the concrete 5 to prevent the floating.

In this way, if the lath net 2 is locked by the fasteners such as the staples 6a, 6b with return in addition to the adhesive 8, the synthetic resin foam concrete formwork 1a of the lath net 2 can be obtained. Will be more firmly locked. Therefore, for example, even if the adhesive 8 is heated and melted during a fire, the lath net 2 can be prevented from falling off.

As shown in FIG. 20, the method for attaching the lath net 2 to the synthetic resin foam concrete formwork 1a according to the eighth embodiment is the same as in the seventh embodiment, before the concrete 5 is poured. The lath net 2 is partially adhered by an adhesive 8 and is locked by the staples 6a and 6b (retaining members) with return hooks to the separator 3 and the concrete 5 so as to prevent them from floating.

In this way, if the lath net 2 is suspended in advance, the synthetic resin foam concrete formwork 1a can withstand the impact force caused by the placing of the concrete 5 by the same amount as above. There are advantages.

In the above first to eighth embodiments, the means for connecting the two synthetic resin foam concrete forms 1a and 1b by the separator 3 so as to face each other at a predetermined interval is described above. Both ends of the separator 3 are connected to the two synthetic resin foam concrete molds 1a,

Furthermore, as shown in FIG.
When locking is performed with a locking tool such as staples 6a and 6b with return, the resin mortar 27 and the like may be entirely applied to the outer surface 1c of the synthetic resin foam concrete formwork 1a in advance. In this case, since the lath net 2 is added to the resin mortar 27 and is locked by the locking tool, the lath net 2 is locked more firmly and the adhesive 8 described above is used. Similarly to the above, even if the resin mortar 27 is heated and melted during a fire, the lath net 2 can be prevented from falling off.

In addition, the two concrete forms 1

As with the junction without being removed, it can be one of the concrete form outwardly facing at least the structure to construction the insulation underlying and insulating wall or the like made of a synthetic resin foam. Therefore, at least one of the synthetic resin foam concrete molds exhibits heat insulation properties, and can improve heat retention in the underfloor space and the indoor space.

Since it is not necessary to remove the concrete formwork, the workability can be improved.
Further, since the lath net is locked to at least one of the separator and the concrete by the locking tool, the locking tool can be prevented from coming off easily, and therefore the lath net is more firmly attached to the outer surface of the synthetic resin foam concrete formwork. Can be locked to.

Further, when the locking tool is locked to concrete, the locking tool can be driven in a state where the concrete is not solidified, which is advantageous in that the work is simple.

In addition, since the lath net is locked before the concrete is poured, there is an advantage that the synthetic resin foam concrete formwork can withstand the striking force associated with the concrete pouring.

According to the third aspect of the present invention, after the two concrete formwork is separated by the separator at a predetermined interval, concrete is placed inside the formwork, and one of the composites facing the outside of the structure is mixed. The lath net is partially adhered to the outer surface of the resin foam concrete formwork by an adhesive so that the lath net is prevented from floating. Therefore, the same effect as in claim 1 can be obtained. Since it can be easily locked to the foam concrete formwork, the workability can be further improved.

According to the invention described in claim 4, after the two concrete forms are separated by a separator at a predetermined interval, the outer face of one of the synthetic resin foam concrete forms facing the outside of the structure. The lath net is fixed to the top by partially adhering it with an adhesive, and then,
Since concrete is poured into the inside of the two concrete forms, the strength of the synthetic resin foam concrete form is improved in addition to the effect of the above-mentioned claim 3, and by that much, the impact at the time of placing concrete etc. There is an advantage of becoming stronger.
