Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lath-structured wall body provided with a foamed resin plate and a lath net and completed as a wall of a building such as a detached house by blasting mortar after standing, and a method for manufacturing the same.

[0002]

2. Description of the Related Art Generally, when constructing a wall of a building, for example, columns are erected at appropriate intervals, a plywood is struck on the stanchions, and a lath net is applied to the outside of the plywood via waterproof paper to form a stepper. It is widely known that the glass wool is attached to the inside of the plywood board while the mortar is sprayed from the outside of the plywood board with the above. However, since such a method requires a lot of man-hours for construction, conventionally, a composite panel has been proposed in which a thin cement layer rich in unevenness is formed on one side of the veneer plate. This composite panel is sequentially struck on the pillars erected at the construction site, and while the cement layer is sprayed with mortar, if the glass wool for heat insulation is attached to the inside of the composite panel, the construction is completed, so the waterproof paper in the previous method Also, the work of attaching the lath net can be eliminated, and the number of construction steps can be reduced accordingly.

[0003]

However, when dew condensation occurs on the inside of the veneer plate due to the temperature difference by any of the methods, the glass wool gradually absorbs this dew condensation and deteriorates, and after several years, it functions as a heat insulating material. The problem of disappearing occurs.

Therefore, a grid-like wire mesh made up of steel wires having a diameter of about 2 to 4 mm is positioned on both sides of the foamed resin plate, and two beams are formed by a large number of beam-like wire mesh materials penetrating the foamed resin plate. It is conceivable to adopt a method of constructing a wall body by welding and fixing the grid-like wire mesh of No. 1, and erected this wall body and spraying mortar on both sides to construct the wall, and this method causes dew condensation. Also, due to its self-sustaining property, the construction is easy and the number of steps can be reduced (see, for example, Japanese Patent Laid-Open No. 5-2230897).

However, the method of spraying the mortar onto the foamed resin plate with a wire mesh inevitably makes the wall thick because of its structure, and is not suitable for use in the wall of a detached house, and the cost is high. In addition, since the mortar surface has a property that irregularities are raised according to the shape of the lattice-shaped wire net, there is a problem that finishing work is inevitably required and it takes much labor.

Further, since the mortar and the foamed resin have a slight water permeability, there is a concern in constructing the outdoor wall.

The present invention has been made by paying attention to such a point, and an object of the present invention is to combine a foamed resin plate and a lath net and integrate them to secure heat insulation. In addition to being able to take measures against dew condensation, it is possible to reduce the number of construction steps by ensuring independence.Also, it is possible to apply thin walls and mortar can be applied with a uniform thickness to eliminate the need for finish coating. It is to provide the provided wall body at low cost. It is also an object to propose a method for manufacturing such a wall body.

A lath net or a reinforcing member heated to a temperature higher than the melting temperature of the foamed resin plate is pressed thereon, and then the whole is cooled.

[0014]

In the lath-clad structure wall body according to claims 1 and 2, when the wall is constructed by spraying mortar onto the lath net, since a foamed resin plate is used, dew condensation does not occur and the heat insulating property is maintained without deterioration. Will be demonstrated. Further, since the lath net and the foamed resin plate are integrated directly or via the reinforcing member, the rigidity of the lathed structure wall body is improved, the self-supporting property is obtained, and the number of construction steps is reduced. Further, since a lath net much thinner than the lattice-like metal net is attached to the foamed resin plate, it is possible to apply even a thin wall. Further, since a lath net having a finer mesh than that of a grid-like wire net is used, the mortar adheres with a substantially uniform thickness. Moreover, since the waterproof layer exhibits waterproofness, moisture does not enter the inside of the foamed resin plate.

In the lath-clad structure wall body according to the second aspect, a gap may be formed between the lath net and the foamed resin plate through the reinforcing member. In that case, mortar is inserted into the gap to form the lath net. The mortar is hardened as it is held, so that the wall strength is improved and the mortar can be formed thick.

Furthermore, the tertiary foaming of the foamed resin plate improves the holding force of the lath net or the reinforcing member by the foamed resin plate.

[0024]

EXAMPLES Examples will be described below. 1 to 3 show a first embodiment of a lath structure wall according to the present invention. In the figure, reference numeral 10 denotes a foamed resin plate, and a waterproof layer 11 is formed on one side surface of the foamed resin plate 10 and a lath net 20 is attached. The waterproof layer 11 is formed on the entire one surface of the foamed resin plate 10 by a known adhesive having a drainage property. The adhesive also has a function of attaching the lath net 20 to the foamed resin plate 10. That is, the lath net 20 partially penetrates the waterproof layer 11 in the thickness direction, and the rest remains exposed to the outside. Here, the foamed resin plate 10 has a size of, for example, a sub block (length: 1800 mm, width: 900 mm) of 50.
Although the thickness is about mm, this is an example and other dimensions may be used. Further, as the material, for example, foamed polyolefin represented by foamed polypropylene, foamed polyethylene, etc., styrene foam, urethane foam, foamed vinyl chloride, etc. can be used, but the material is not limited as long as it is a plate made of foamed resin. On the other hand, the lath net 20 is, for example, a well-known one in which a large number of holes are formed in a thin plate as shown in FIGS. And those which are manufactured by a method of stretching in the lateral direction) and known ones formed by braiding a thin steel wire can be used.

The method of constructing a wall using the lath-clad structure wall body of the first embodiment is basically the same as that of the lath-clad structure wall body as shown in FIG. This is completed by sequentially striking and standing upright and spraying mortar m onto the lath net side of the lath structure wall as shown in FIG. After that, if necessary, coating may be applied to the surface of the mortar, or wallpaper may be attached to the surface of the foamed resin plate on the side opposite to the lath net. Further, the joints formed between the lath structure wall bodies may be filled with caulking material or the like.

Next, a method of manufacturing the lath structure wall body of the first embodiment will be described. First, an adhesive is applied to the entire one side surface of the foamed resin plate 10 with a roller or the like, and the lath mesh 2 is applied thereon.
Press 0 to attach and dry the adhesive to complete manufacturing.

Therefore, in the lathed structure wall body of the first embodiment, when the wall is constructed, since the foamed resin plate 10 is used, dew condensation does not occur and the heat insulating property is continuously exhibited without deterioration. To be done. And the lath net 20 is the foamed resin plate 1
Since it is integrated with No. 0 by an adhesive, the rigidity of the lathed structure wall body is improved. For this reason, the lath-clad structure wall body can be self-supporting, the wall body can be easily erected, and the number of construction steps can be reduced.
By being integrated with the foamed resin plate 10, the lath net 20 is securely fixed, its deformation is prevented, and the mortar m is not cracked. Furthermore, since the lath net 20, which is much thinner than the lattice-shaped metal net or the like, is attached to the foamed resin plate 10,
The thickness of the wall can be made thin, and therefore, even a thin wall can be constructed. Further, since the lath net 20 having a finer mesh than that of the grid-like metal net is used, the mortar m adheres with a substantially uniform thickness, and the finishing work is unnecessary and the construction is easy. Further, the manufacturing cost is lower than that of a foamed resin plate with a lattice-shaped wire mesh.

Further, since the waterproof layer 11 exerts waterproofness over the entire surface of the foamed resin plate 10, moisture does not enter the inside of the foamed resin plate 10 and is suitable for constructing an outdoor wall. Furthermore, the lath net 20 can be attached to the foamed resin plate 10 using an adhesive that forms the waterproof layer 11. If an adhesive is used, the lath net 20 can be attached without chemically deteriorating the foamed resin plate 10 and the waterproof layer 11.

Further, according to the above manufacturing method, the work is simple, and the production efficiency of the lath structure wall can be improved.

In the first embodiment, one side of the lath net 20 is adhered to the foamed resin plate 10 over the entire surface, but it is necessary to apply the adhesive on the entire surface in order to ensure the waterproof function. As for the lath net, a part of the lath net may be adhered to the foamed resin plate. For example, a convex portion may be formed at a required portion of the lath net, and only this convex portion may be adhered to the foamed resin plate. Alternatively, a convex portion may be formed in a required portion of the foamed resin plate, and the lath net may be bonded only to the convex portion of the foamed resin plate. By doing so, a gap is formed between the lath net and the foamed resin plate except for the periphery of the adhered convex portion, so that the mortar m enters the gap to solidify the lath net by embracing it. As a result, the wall strength is improved and the mortar m can be formed thick.

FIG. 5 shows a lath structure wall of the second embodiment. In the second embodiment, the entire lath net is formed in a wavy shape. That is, as shown in FIGS. 6 and 7, lath net 20 '
Is a shutter-shaped door formed by inserting a large number of slits in a thin steel plate and raising the slits at an angle, and is curved and formed in a wavy shape as a whole. The waterproof layer 11 'is formed on one side surface of the foamed resin plate 10' and the lath net 2 is formed.
0'is attached at the bent portion. The action, effect, construction method and manufacturing method are first
It is similar to the embodiment.

FIG. 8 and FIG. 9 show a lath structure wall of the third embodiment. In the third embodiment, the waterproof layer 111 is formed on one side surface of the foamed resin plate 110 and the lath net 121 is formed.
Are attached via the reinforcing member 122. That is, the waterproof layer 111 is formed of a waterproof film molded of resin or the like. A plurality of reinforcing members 122 are fixed to one side surface of the lath net 121.
However, the foamed resin plate 110 is fitted in a plurality of recesses 112 formed by heat fusion. The lath network 121 may be, for example, the one shown in the first embodiment or the one shown in the second embodiment. In addition, the reinforcing member 122
Is made of steel wire, one end of which is welded to the lath net 121 and the other end of which is bent to be L-shaped and is fitted into the recess 112. The recess 112 has an opening whose shape is substantially the same as the projected shape of the reinforcing member 122 on the foamed resin plate 110, and has a depth such that the reinforcing member 122 is partially inserted.

The method of constructing a wall using the lath structure wall body of the third embodiment is the same as that of the first embodiment, but the manufacturing method thereof is different from that of the first embodiment. First, as shown in FIG. 11, a lath net 121 with a reinforcing member 122 is sandwiched between a pair of heat generating plates 31 and 32 provided so as to be movable in the vertical direction and the horizontal direction, respectively. The lath net 121 and the reinforcing member 122 are heated to a temperature exceeding the melting temperature of the foamed resin plate 110 to preheat the lath net 121 and the reinforcing member 122. Here, one heating plate 31 can be magnetized by a switching operation. The sandwiching between the heat generating plates 31 and 32 is performed so that the reinforcing member 122 contacts the heat generating plate 32 and the lath net 121 contacts the heat generating plate 31, respectively. The preheating temperature is, for example, the foamed resin plate 110.
If the polystyrene is expanded polystyrene, 180 to 20 degrees Celsius
It will be about 0 degrees. Next, one heating plate 31 is switched to be magnetized and the other heating plate 32 is retracted while the lath net 121 and the reinforcing member 122 are attached, and instead, the waterproof film 111 is provided on the upper surface as shown in FIG. The foamed resin plate 110 on which is attached is carried in while being held by the carrier 40, and the heat generating plate 31 is lowered to press the reinforcing member 122 against the foamed resin plate 110 while being heated. Then, the heated reinforcing member 122 causes the waterproof film 11
1'and the foamed resin plate 110 are melted and penetrated to form a recess 112. After that, the heating plate 31 is switched so as to be demagnetized, the lath net 121 is separated and retracted, and cold air or cold water is applied to the foamed resin plate 110, the lath net 121, and the reinforcing member 122 to cool the whole to manufacture. Complete. At this time, as shown in FIG. 9, the vicinity of the opening of the recess 112 is narrowed by the tertiary foaming. Further, the pressing of the reinforcing member 122 against the foamed resin plate 110 is stopped so that a predetermined gap remains between the lath net 121 and the foamed resin plate 110.

The operation and effect of the lathed structure wall body of the third embodiment is almost the same as that of the first embodiment. That is, when the wall is constructed, the foamed resin plate 110 is used, so that dew condensation does not occur. Insulation is sustained without deterioration. Then, the reinforcing member 122 is heat-welded to the foamed resin plate 110 so that the lath net 121 and the foamed resin plate 110 are reinforced.
The rigidity of the lathed structure wall body is improved because it is integrated through the two. As a result, the lath-clad structure wall body is self-supporting, the wall body can be easily erected to reduce the number of construction steps, and the lath net 121 is securely fixed to prevent its deformation, and the mortar m is not cracked. Do not fit. Further, since the lath net 121, which is much thinner than the lattice-shaped metal net or the like, is attached to the foamed resin plate 110, the wall thickness can be made thin, and therefore even a thin wall can be constructed. Further, since the lath net 121 having a finer mesh than the grid-like metal net is used, the mortar m adheres with a substantially uniform thickness, and the finishing work becomes unnecessary and the construction is easy. Moreover, the manufacturing cost is lower than that of a foamed resin plate with a lattice-shaped wire mesh.

Further, since the waterproof layer 111 exerts waterproofness over the entire surface of the foam resin plate 110, the foam resin plate 110
Water does not enter the inside of the room, making it ideal for building outdoor walls. Further, according to the waterproof film 111 ', the waterproof layer 11
It is easy to make the thickness of 1 uniform.

Further, according to the above manufacturing method, the work is simple and the production efficiency of the lath structure wall can be improved.

Since there are a plurality of concave portions 112 and a plurality of reinforcing members 122 respectively, the holding force of the reinforcing member 122 is further increased by the mutual action of the frictional force between the side wall of the concave portion 112 and the reinforcing member 122 and the like. Get higher That is, the lath net 121 and the reinforcing member 122 are attached to the foamed resin plate 11
Even if one tries to peel it from 0, at least a part of the recess 112
Due to the frictional force between the side wall of the sheet and the reinforcing member 122, etc., it is in a “pryed state” and does not peel off. In addition, since the vicinity of the opening of the recess 112 is narrowed by the tertiary foaming, the reinforcing member 122 is firmly held in the recess 112. Furthermore, the reinforcing member 12
Since a gap is formed between the lath net 121 and the foamed resin plate 110 via the two, the mortar m enters the gap and solidifies so as to hold the lath net 121, thereby improving the wall strength and also the mortar. m can be formed thick.

In the case of the third embodiment, as shown in FIG. 10, the recess 112 may be filled with an adhesive 113 or the like so as to completely close the recess 112. In that case, a lath net is used. Since the 121 and the foamed resin plate 110 are more strongly integrated, the rigidity of the lath-structured wall body is improved. In the case of the manufacturing method in that case, the lath net 121 and the reinforcing member 122 may be heated after applying an adhesive or the like to the reinforcing member 122 and pressed against the foamed resin plate 110 while being heated. Further, the waterproof film 111 ′ may be adhered to the foamed resin plate 110 with an adhesive.

FIG. 13 shows a lath structure wall of the fourth embodiment. In the fourth embodiment, the reinforcing member is the truss structure 222, the reinforcing member 222 is fixed to one side surface of the lath net 221, and the reinforcing member 222 is fitted into the concave portion 212 formed by heat melting in the foamed resin plate 210. This is the configuration. That is, as shown in FIG. 14, the reinforcing member 222 includes two grid-shaped wire nets 222a, 222 made of steel wires.
22b are arranged at intervals, and these are connected to the beam-shaped wire mesh material 22
It is connected by 2c. The beam-shaped wire mesh material 222
The c is arranged so that the grid-like wire nets 222a and 222b that connect the opposing vertical bars are parallel to each other, and the adjacent bars cross each other along the axial direction of the horizontal bars. Depending on the configuration, the strength of the reinforcing material as a whole is increased. Then, the lath net 221 is fixed to one lattice-like metal net 222a by welding. The lath net 221 may be, for example, the one shown in the first embodiment or the one shown in the second embodiment. The recessed portion 212 is formed such that the opening shape thereof is substantially the same as the projected shape of the lattice-shaped metal mesh 222a on the foamed resin plate 210 and the depth is such that the beam-shaped metal mesh material 222c is inserted halfway.

The method of constructing a wall using the lath-clad structure wall of the fourth embodiment is the same as that of the first embodiment. The method of manufacturing the lath-clad structure wall body is the same as that of the third embodiment, and the lath net 221 and the reinforcing member 222 are pressed against the foamed resin plate 210 at a predetermined distance between the lath net 221 and the foamed resin plate 210. Try to stop when there is a gap.

The operation and effect of the lath-clad wall of the fourth embodiment is almost the same as that of the third embodiment, but the reinforcing member 2 is used.
Since 22 is a truss structure, its rigidity further improves the rigidity of the lathed structure wall body, the deformation of the lath net 221 is reliably prevented, and the mortar m is not cracked. Note that the recess 212 may be filled with an adhesive or the like as in the third embodiment.

In the third embodiment, the steel wire reinforcement member 122 is used.
However, a grid-shaped wire mesh may be used as the reinforcing member. A further modification thereof is the lath-clad structure wall body of the fifth embodiment shown in FIG. That is, as shown in FIG. 16, a grid-like wire mesh is used as the reinforcing member 322, and the reinforcing member 322 is fixed to one side surface of the lath net 321.
Is fitted in a recessed portion 312 formed by heat melting in the foamed resin plate 310. Here, the lath net 321 has a convex portion 321a formed at a required position, and the convex portion 321a is fixed to the reinforcing member 322 by welding or the like.
The lath net 321 is, for example, the one shown in the first embodiment and the second one.
It may be the one shown in the embodiment. The recessed portion 312 is formed so that the opening shape thereof substantially matches the projection shape of the reinforcing member 322 on the foamed resin plate 310 and the depth thereof matches the thickness of the reinforcing member 322.

The method of constructing a wall using the lath-clad structure wall body of the fifth embodiment is the same as that of the first embodiment. The method of manufacturing the lath-clad structure wall body is the same as that of the third embodiment, and the lath net 321 and the reinforcing member 322 are pressed against the foamed resin plate 310 in a predetermined manner between the lath net 321 and the foamed resin plate 310. Try to stop when there is a gap.

The operation and effect of the lath-clad wall of the fifth embodiment is almost the same as that of the third embodiment, but the reinforcing member 3 is used.
Since 22 is a lattice-shaped wire net, the rigidity thereof further improves the rigidity of the lath structure wall body, the deformation of the lath net 321 is reliably prevented, and the mortar m is not cracked. Note that the recessed portion 312 may be filled with an adhesive or the like as in the third embodiment.

In the first to fifth embodiments described above, the structure of the waterproof layer was specified, and whether the lath net was directly attached to the foamed resin plate or the reinforcing member was attached thereto. All combinations of the three requirements are considered as examples. The waterproof layer can be formed by an adhesive or a waterproof film, and can also be formed by applying a tar-based material such as coal tar and drying it, and at that time, a rust preventive function is also exerted. Further, the waterproof layer can be formed by the surface of the molten foamed resin plate. The specific method is to heat the surface of the foamed resin plate with a burner or the like or to chemically react by spraying chemicals or the like, but a method of attaching a lath net or a reinforcing member to the foamed resin plate by heat welding (for example, According to the third to fifth embodiments), as long as the lath net or the reinforcing member is not coarse, a regenerated layer which is melted and solidified by heat welding is formed over the entire surface of the foamed resin plate during heat welding. Therefore, it is possible to form a waterproof layer with this reproduction layer,
This is also one mode in which the waterproof layer is formed by the surface of the molten resin foam plate. As described above, the waterproof layer formed by melting on the surface of the foamed resin plate is rich in irregularities, so that the adhesion of mortar can be promoted.

In the third to fifth embodiments, the heated lath body was pressed against the foamed resin plate to produce a lath-structured wall, but a jig having the same shape as the auxiliary member of the lath body was used. Prepared separately, heat this jig and press it against the foamed resin plate to form a recess, then separate the jig from the foamed resin plate, and then insert an auxiliary member of lath body into the recess, You may make it manufacture a structural wall body. Further, in any of the above embodiments, the material of the lath net and the reinforcing member does not have to be steel, and may be formed of another metal such as an aluminum alloy. Further, it may be a resin.
In that case, the reinforcing member needs to be made of a material having a higher melting temperature than the foamed resin plate.

In each of the above embodiments, the flat lathed structure wall has been described. However, the present invention is a lathed structure wall having an L-shaped cross section for use in a corner portion (for example, a protruding corner structure or an inside corner structure). It can also be applied to the body. Further, when manufacturing a lath-clad structure wall body, an adhesive or a material capable of exhibiting an anticorrosive function such as coal tar is applied to the lath net or the lath net and the reinforcing member and then attached to the foamed resin plate. No rust will appear on the constructed wall for a long time. Further, in each of the above-described embodiments, the waterproof layer is formed only on one side of the foamed resin plate, and the lath net or the lath net and the reinforcing member are arranged. However, the waterproof layer is formed on both sides of the foamed resin plate and both sides are formed. The present invention also includes a lath net or a lath net and a reinforcing member arranged therein.

[0048]

As described above, in the lath-clad structure wall body according to claim 1, a waterproof layer is formed on one side surface of the foamed resin plate and a lath net is attached, and the lath-clad structure wall body according to claim 2 is Since a waterproof layer is formed on one side of the foamed resin plate and a lath net is attached via a reinforcing member, no condensation occurs when the wall is constructed by spraying mortar onto the lath net, ensuring long-term heat insulation. In addition, the lath net and the foamed resin plate can be integrated to improve the rigidity of the lathed structure wall body, which ensures independence, simplifies construction, and reduces man-hours. This makes it suitable for single-family homes where space is especially required, and it does not require finishing work by uniformly adhering mortar etc., and the manufacturing cost is much lower than conventional walls. Further moisture inward of the foamed resin plate can be reliably prevented from entering the waterproof layer,
It is also ideal for building outdoor walls.

In the lath-clad structure wall body according to a second aspect of the present invention, when the gap is formed between the lath net and the foamed resin plate via the reinforcing member, the mortar is solidified so as to embrace the lath net, so that the wall strength is improved. In addition, the mortar can be formed thick.

In the lath-clad structure wall body according to the third aspect, since the waterproof layer is formed by the adhesive, the lath net or the reinforcing member can be attached to the foamed resin plate by using the adhesive. Further, in the lath-clad structure wall body according to the fourth aspect, since the waterproof layer is formed of the tar-based material, the rustproof function is exhibited. Further, in the lathed structure wall body according to the fifth aspect, since the waterproof layer is formed of the waterproof film, it is easy to make the thickness of the waterproof layer constant. Further, since the lathed structure wall body according to claim 6 is formed on the surface of the foamed resin plate in which the waterproof layer is melted, the waterproof layer can be formed by heating or chemically reacting the surface of the foamed resin plate. The unevenness of the surface can promote the adhesion of mortar.

Since the reinforcing member is attached by the adhesive in the lath-clad structure wall body according to the seventh aspect, the lath net or the reinforcing member can be attached without deteriorating the foamed resin plate and the waterproof layer. Further, since the reinforcing member is attached by heat welding to the lathed structure wall body according to claim 8, the retaining force of the lath net or the reinforcing member by the foamed resin plate can be improved by tertiary foaming of the foamed resin plate, and the molten portion of the foamed resin plate can be improved. Thus, the waterproof layer can be formed at the same time, and the unevenness of the surface of the waterproof layer can promote the adhesion of mortar.

In the method of manufacturing the lath-clad structure wall body according to the ninth aspect, since the adhesive is applied to one side of the foamed resin plate and the lath net or the reinforcing member is attached thereon, the waterproof layer can be formed by the adhesive. At the same time, a lath net or a reinforcing member can be attached. Further, the method for producing a lath-clad structure wall body according to claim 10 applies a waterproof film to one side of a foamed resin plate, and presses a lath net or a reinforcing member heated thereon to a temperature higher than the melting temperature of the foamed resin plate, Since the whole is then cooled, the waterproof film and the foamed resin plate can be fixed by heat welding, and a waterproof layer can be formed by this waterproof film, and a lath net or a reinforcing member can be attached to the foamed resin plate by heat welding. Moreover, the retaining force of the lath net or the reinforcing member by the foamed resin plate can be improved by the third foaming of the foamed resin plate. And in any manufacturing method, the work is simple and the production efficiency of the lath structure wall can be improved.
