PURPOSE: To enhance the insulating properties and workability by erecting a lath-thermowelded and lath-attached structural wall made on the side surfaces of a foaming resin board and placing concrete to the lath net side, using the structural wall member as a molding form. CONSTITUTION: A lath net is laid out on both sides of a foaming resin board while they are thermowelded, thereby forming a lath-attached structural wall member BB. Then, reinforcing bars are installed on a foundation A while the lath-attached wall member BB is erected with the reinforcing bars clamped on one side. The structural wall member BB and a molding form are fixed with each other alternately. Then, concrete is cast between the lath-attached structural wall member BB and the molding form and cured. Furthermore, after the molding form is removed, mortar is adapted to be deposited on the lath net opposite to the foundation side A of the lath-attached structural wall member BB, thereby forming an exterior wall.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating structure in the foundation of a building, and more particularly to a heat insulating structure provided by using a lath-structured wall formed by integrating a lath net with a foamed resin plate.

[0002]

2. Description of the Related Art Conventionally, as a foundation of a building in a cold region, a resin foam plate is joined to a side surface of a concrete foundation,
It is known that the heat insulation of the foamed resin plate improves the heat retention of the underfloor space. As a construction method, there is a method of separately attaching a foamed resin plate after placing a concrete foundation by adhesion or the like, but as a method of further improving workability, a foamed resin plate is placed inside a mold called a control panel. There is a method of pouring the concrete for the foundation inside it, removing the form after the concrete has solidified, and at the same time placing the concrete foundation and adhering the foamed resin plate due to its affinity to the concrete etc. .

[0003]

However, the latter method also requires a mold for supporting the foamed resin plate, which is very troublesome in construction.
Moreover, since the foamed resin plate is only bonded due to its affinity for concrete or the like, its bonding strength is weak. In that case, it is conceivable to fix the lath net on one side of the foamed resin plate and place concrete on the lathed net side to increase the bonding force between the foamed resin plate and the concrete. Since the lath net is fixed only by wire, it becomes a very troublesome work.

The present invention has been made by paying attention to such a point, and an object thereof is to bond a foamed resin plate to concrete through a lath net, and in that case, the foamed resin plate and the lath By firmly preliminarily integrating the net with the net, the binding force between the foamed resin plate and the concrete is increased and the workability is improved, and at the same time, the foamed resin plate and lath net alone ensure sufficient self-sustainability. It is to improve the workability by making it possible to place concrete without the support of. Also, mortar and the like can be surely attached to the surface of the foamed resin plate opposite to the concrete foundation.

[0005]

In order to achieve the above object, in the heat insulating structure according to claim 1, the lath-tensioned structure wall body in which a lath net is heat-welded to at least one side surface of a foamed resin plate is a concrete foundation. The lath net side is joined to at least one side surface of the.

According to a second aspect of the present invention, there is provided a heat insulating structure according to the first aspect of the present invention, in which the lath net is heat-welded to at least one side surface of the foamed resin plate in place of the lath structure wall body. A lath-tensioned structural wall body including a lath body having a reinforcing member fixed to one side surface of a lath net and a foamed resin plate having a concave portion formed by heat fusion and into which the reinforcing member fits are provided on at least one side surface. It is configured.

According to a third aspect of the present invention, in the heat insulating structure according to the first or second aspect, the lath net or the lath body is formed on the other side surface of the lath structure wall body by heat welding or by fitting into the concave portion of the reinforcing member. It is attached, and concrete or mortar adheres to the lath net on the other side.

According to a fourth aspect of the present invention, there is provided a method of constructing a heat insulating structure according to any one of the first to third aspects, in which a lath structure wall is erected and the lath structure wall is used as a formwork.
Concrete is placed on the lath net side.

[0009]

In the first aspect, the heat insulation of the foamed resin plate improves the heat retention of the underfloor space. Further, since the foamed resin plate is bonded to the concrete through the lath net and the foamed resin plate and the lath net are firmly integrated with each other, the bonding force between the foamed resin plate and the concrete is high. Further, if a lath-clad structure wall is made in advance and a heat insulating structure is constructed using this, workability is improved. In that case, since the lath-clad structure wall alone has sufficient self-sustainability, concrete can be poured without the support of the formwork, and the workability is further improved.

The action of the lathed structure wall body of the second aspect is the same as that of the first aspect. In that case, when there are a plurality of recesses, the holding strength of the reinforcing member is further increased by the mutual action of the frictional force between the side wall of the recess and the reinforcing member and the like. Further, since the vicinity of the opening of the concave portion is narrowed by the tertiary foaming, the reinforcing member is firmly held in the concave portion (here, the foamed resin plate is produced, for example, by secondary foaming pre-expanded particles. Foaming refers to foaming subsequent to the above secondary foaming). In addition, since a gap is formed between the lath net and the foamed resin plate through the reinforcing member, the mortar enters the gap and solidifies as if the lath net is held in the gap, whereby the bonding force between the foamed resin plate and concrete is increased. improves.

According to the third aspect, the mortar and the like are surely attached to the foamed resin plate by the lath net even on the other side surface of the lath structure wall.

[0012]

EXAMPLES Examples will be described below. 1 and 2 are
The 1st Example of the heat insulation structure which concerns on this invention is shown, and is applied to the foundation of the building in a cold district. In the figure, A is a concrete foundation, BB is a lath structure wall standing upright on one side of the foundation A, and m is a mortar layer formed on one side of the lath structure wall BB. The lath-clad structure wall body BB is formed by heat-welding lath nets 20 on both side surfaces of the foamed resin plate 10. The lath-clad structure wall BB is joined to one side surface of the base A on the lath net side.

Here, the lath structure wall BB will be described in detail. As shown in FIGS. 3 to 5, lath nets 20 are directly arranged on both side surfaces of the foamed resin plate 10, and each lath net 2 is
One side of 0 is heat-welded to the foamed resin plate 10 over almost the entire surface. That is, a part of the lath net 20 enters the foamed resin plate 10 in the thickness direction and is heat-welded, and the rest remains exposed to the outside. Here, the foamed resin plate 10 is, for example, a sub block (length 1800 mm, width 900 m).
Although the size is about m) and the thickness is about 50 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 known one in which a large number of holes are formed in a thin plate as shown in FIGS. 4 and 5 (for example, after inserting a large number of slits in the thin plate at an angle to the plate surface,
(A plate manufactured by a method of stretching a plate in the longitudinal direction and the horizontal direction), or a known plate formed by braiding a thin steel wire can be used. Further, on the surface of the foamed resin plate 10 on the lath net side, a regenerated layer 13 which is melted and solidified when the lath net 20 is heat-welded is formed. The lath net 20 is subjected to rust prevention treatment or waterproof treatment. That is, the lath net 20 is coated with a tar-based material such as coal tar, an adhesive, or a resin material.

The construction method of the heat insulating structure of the first embodiment is as follows.
A description will be given based on FIG. 6 and FIG. In addition to arranging on the foundation A, the reinforcing bar S is sandwiched between the lathed structure wall B
B is erected so that the lath net 20 is on the outside, and a mold C called a control panel is erected on the other side, and a lath-tensioned structure wall body is formed by using a connecting member called a separator or a support. The BB and the form C are fixed to each other. Then, concrete is placed between the lath structure wall BB and the form C. Then, after the solidification of the concrete, the connecting member, the support and the like are removed, and the form C is removed, and the state shown in FIG. 7 is obtained. After that, the mortar m is attached to the lath net 20 on the surface opposite to the base side of the lath-clad structure wall body BB to complete the outer wall.

Next, a method of manufacturing the above lath structure wall BB will be described. First, as shown in FIG.
The heating plate 3 is sandwiched between a pair of heating plates 31 and 32 provided so as to be movable in the vertical direction and the horizontal direction, respectively.
The lath net 20 is preheated by heating the lath net 20 to a temperature exceeding the melting temperature of the foamed resin plate 10 with 1, 32. The preheating temperature may be 80 degrees Celsius or higher when the foamed resin plate 10 is foamed polystyrene, for example, preferably 100 to 210 degrees Celsius, and more preferably 1 degree Celsius.
It is about 20 to 200 degrees, and can be appropriately selected depending on the pressing time and the pressing pressure into the foamed resin plate 10. Next, one heating plate 31 is retracted, and instead, the foamed resin plate 10 is carried in while being held by the carrier 40 as shown in FIG. 9, and the other heating plate 32 is raised to heat the lath net 20. Until it is pressed against the foamed resin plate 10,
A part of the lath net 20 is heat-welded to the foamed resin plate 10. After that, the heat generating plate 32 is retracted away from the lath net 20, and the whole is forcibly cooled by applying cold air or cold water to the foamed resin plate 10 and the lath net 20. By applying an adhesive or the like, rustproofing treatment or waterproofing treatment is performed, and the treatment on one side is completed. The method of heat welding the lath net 20 to the other side surface is performed in the same manner as above,
When this step is completed, manufacturing is completed. The manufacturing method is not limited to this, and it goes without saying that the lath net 20 can be heated in a hot-air oven, the lath net 20 can be pressed against the foamed resin plate 10, or the foamed resin plate 10 can be pressed. is there. According to the above manufacturing method, the production efficiency of the lath structure wall BB can be improved.

Therefore, in the first embodiment, the heat insulation of the foamed resin plate 10 improves the heat retention of the underfloor space. In addition, the foamed resin plate 10 is connected to the base A through the lath net 20.
Since the foamed resin plate 10 and the lath net 20 are firmly integrated with each other, the bonding force between the foamed resin plate 10 and the concrete is increased. Further, since the lath-clad structure wall body BB is prepared in advance and the heat insulating structure is constructed using this, workability is improved as compared with attaching the lath net 20 to the foamed resin plate 10 at the construction site. Moreover, since the lath-clad structure wall body BB alone has sufficient self-sustainability, it is not necessary to provide a formwork for directly supporting the lath-clad structure wall body B on the side opposite to the side where concrete is placed, and therefore further construction is required for that purpose. The property is improved.

On the other side of the lath-clad structure wall BB, the mortar m is formed by the lath net 20 to form the foamed resin plate 1.
Since it surely adheres to 0, the mortar m does not peel off or crack.

Further, the lath-structured wall BB having the above structure
By using, the following effects can be obtained. First,
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 wall thickness can be made thin, and therefore a thin foundation can also be applied. 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, on the surface of the foamed resin plate 10, there is formed a regenerated layer 13 which is melted and solidified when the lath net 20 is heat-welded, and the regenerated layer 13 exerts a waterproof function and the unevenness of the surface promotes adhesion of the mortar m. . Moreover, since the lath net 20 is subjected to rust prevention treatment or waterproof treatment, the lath net 20 is not rusted for a long period of time, or repels water to improve the durability of the wall.

FIG. 10 shows a second embodiment. In the first embodiment, the lath-clad structure wall body BB (hereinafter referred to as the double-sided lath-structured wall body BB) in which the lath nets 20 are heat-welded to both side surfaces of the foamed resin plate 10 is used. Then, the lath tension structure wall body B (hereinafter referred to as the single-sided lath tension structure wall body B) in which the lath net 20 is heat-welded only to one side surface of the foamed resin plate 10 was used. Therefore, the mortar m on the other side
Was not applied. Therefore, the same effect as that of the first embodiment can be obtained except for the decorative effect and the like obtained by the mortar adhesion. Further, FIG. 11 shows a third embodiment. In the first embodiment, one side of the foundation A is formed by the form C,
Although this form C was removed after the concrete of the foundation A was solidified, in the third embodiment, instead of this form C, a single-sided lath structure wall B was erected, and both lath structure walls BB,
Concrete is poured between B and both of the lath structure wall bodies BB and B are left as they are after the solidification. According to the third embodiment, the heat insulation can be further improved, and the workability can be further improved because the mold C does not need to be removed. Further, FIG. 12 shows a fourth embodiment. In this embodiment, the single-sided lath structure wall bodies B are erected on both sides of the foundation A, and the both-side lath structure wall bodies B, B are provided.
Concrete is poured between the walls, and both the lath-structured walls B and B are left as they are even after the solidification, so that an effect similar to that of the third embodiment can be obtained.

As described above, in the first to fourth embodiments, the double-sided lath structure wall body BB and the single-sided lath structure wall body B are properly combined to form the heat insulating structure. A modified example of the wall itself is shown below. In order to simplify the explanation, only the one-sided lath structure wall body B will be described as a modified example, and the description of the double-sided lath structure wall body BB will be omitted as it follows this.

First, FIG. 13 shows a first modification of the one-sided lath structure wall B. In this modification, the entire lath net is formed in a wavy shape. That is, as shown in FIGS. 14 and 15, the lath net 20 ′ is a door-shaped door formed by inserting a large number of slits in a thin steel plate and diagonally raising the slits.
Furthermore, it is curvedly formed as a whole. And
A lath net 20 'is arranged on the side face of a foamed resin plate 10' having a groove 11 'on one side face, and only the bent portion of the lath net 20' is heat-welded to the foamed resin plate 10 '. The method for manufacturing the lath-structured wall B of the first modification and the method for constructing a heat insulating structure using the same are the same as those in the first embodiment.

A second modification of the one-sided lath structure wall B is shown in FIGS. 16 and 17. In this modification, the lath net 12
A plurality of reinforcing members 122 are fixed to one side surface of the lath body 12
0, the reinforcing member 122 of the lath body 120 is fitted over a plurality of concave portions 112 formed by heat melting in the foamed resin plate 110 on almost the entire surface. The lath net 121 is, for example, the one shown in the first embodiment 20.
However, the thing 20 'shown in the 1st modification may be used. 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 into an L-shape to form the concave portion 11.
It fits in 2. 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 the heat insulating structure using the lath structure wall B of the second modification is the same as that of the first embodiment. Further, the method of manufacturing the lath-clad structure wall body B is the same as that of the first embodiment, except that the lath body 120 is used as the object sandwiched by the pair of heat generating plates 31 and 32. In this case, the reinforcing member 122 is placed on the heating plate 31, and the lath net 121 is placed on the heating plate 32. Then, when the foamed resin plate 110 is carried in while being held by the carrier 40 and the heating plate 32 is raised and the lath body 120 is pressed against the foamed resin plate 110 while being heated, the heated reinforcing member 122 causes the foamed resin member 122 to foam. The plate 110 is melted and invades to form a recess 112, and the vicinity of the opening of the recess 112 is narrowed by tertiary foaming as shown in FIG. After that, the whole is cooled to complete the production. In this case, when the lath body 120 is pressed against the foamed resin plate 110,
It 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 lath structure wall B of the second modified example are almost the same as those of the first embodiment, but further, since there are a plurality of recesses 112 and reinforcing members 122, respectively, The side wall and the reinforcing member 122 interact with each other due to the frictional force, etc.
Holding strength is further increased. That is, even if the lath body 120 is peeled off from the foamed resin plate 110, the lath body 120 is peeled off due to a frictional force between at least a part of the side wall of the recess 112 and the reinforcing member 122. I can't. 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. Further, the lath net 12 is provided through the reinforcing member 122.
Since a gap is formed between 1 and the foamed resin plate 110,
The mortar m enters the gap and is hardened by embracing the lath net 121, thereby improving the wall strength and making the mortar m thick.

In the case of the second modified example, as shown in FIG. 18, the recess 112 may be filled with an adhesive 113 or the like to completely close the recess 112. Since the body 120 and the foamed resin plate 110 are more strongly integrated with each other, the rigidity of the lath structure wall B is improved. In the manufacturing method in that case, for example, after applying the adhesive or the like to the reinforcing member 122, the lath body 120 is heated to
20 may be pressed against the foamed resin plate 110 while being heated.

FIG. 19 shows a third modification of the one-sided lath structure wall B. In this modification, the reinforcing member is the truss structure 222, and the reinforcing member 2 is provided on one side surface of the lath net 221.
22 is fixed to form a lath body 220, and a reinforcing member 222 of the lath body 220 is fitted in a concave portion 212 formed by heat fusion in the foamed resin plate 210. That is, as shown in FIG. 20, the reinforcing member 222 includes two lattice-shaped metal nets 222a, 222 assembled with steel wires.
b are arranged at intervals, and these are arranged like a beam-like wire mesh material 222c.
Are connected by. The beam-like wire mesh material 222c
The grid-like wire nets 222a, 222b are arranged such that the connecting longitudinally-opposing vertical meshes are parallel to each other, and adjacent ones intersect each other along the axial direction of the horizontal stripes. Therefore, the strength of the reinforcing member as a whole is increased. Then, the lath net 221 is fixed to one lattice-shaped metal net 222b by welding. The lath net 221 may be, for example, the one 20 shown in the first embodiment or the one 20 'shown in the first modification. The recess 2
12, the opening shape is substantially the same as the projection shape of the lattice-shaped metal net 222a on the foamed resin plate 210, and the depth is formed so that the beam-shaped metal net material 222c is inserted halfway.

The method of constructing the heat insulating structure using the lathed wall B of the third modification is the same as that of the first embodiment. The method for manufacturing the lath-clad structure wall body B is the same as that of the second modified example. When the lath body 220 is pressed against the foamed resin plate 210, a predetermined gap is formed between the lath net 221 and the foamed resin plate 210. Try to stop it when it remains.

The action and effect of the lathed structure wall body B of the third modified example are almost the same as those of the second modified example, but since the reinforcing member 222 is a truss structure, the rigidity of the lathed structural wall body B is increased. The rigidity of the structural wall is further improved, and the lath net 221
Of the mortar m is prevented and the mortar m is not cracked. Note that the concave portion 212 may be filled with an adhesive or the like as in the second modified example.

In the second modified example described above, the reinforcing member 12 is made of steel wire.
Although 2 is configured, a grid-like wire mesh may be used as the reinforcing member.
A further modification thereof is the lath structure wall B of the fourth modification shown in FIG. That is, as shown in FIG. 22, a lattice-shaped metal net is used as a reinforcing member 322, and a lath net 321 is used.
The reinforcing member 322 is fixed to one side surface of the lath body 320.
The reinforcing member 322 of the lath body 320 is formed in the foamed resin plate 310 by heat melting to form a concave portion 312.
It is a structure that is inserted into. 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. Lath net 32
1 may be, for example, the one 20 shown in the first embodiment or the one 20 'shown in the first modification. The concave portion 312 is
The opening shape is formed so as to substantially match the projection shape of the reinforcing member 322 on the foamed resin plate 310 and the depth thereof to match the thickness of the reinforcing member 322.

The method of constructing the heat insulating structure using the lath structure wall B of the fourth modification is the same as that of the first embodiment. The method for manufacturing the lath-clad structure wall body B is the same as that of the second modified example, and when the lath body 320 is pressed against the foamed resin plate 310, a predetermined gap is formed between the lath net 321 and the foamed resin plate 310. Try to stop it when it remains.

The operation and effect of the lath-clad structure wall body B of the fourth modified example are almost the same as those of the second modified example, but since the reinforcing member 322 is a lattice-shaped wire mesh, the rigidity of the lath-clad structural wall is due to its rigidity. The rigidity of the body is further improved, the deformation of the lath net 321 is reliably prevented, and the mortar m is not cracked. It should be noted that the concave portion 312 is the same as in the second modified example.
It may be filled with an adhesive or the like.

In the second to fourth modified examples, the heated lath body is pressed against the foamed resin plate to manufacture the lath-clad structure wall body, but a jig having the same shape as the reinforcing member of the lath body is separately provided. The jig is heated and pressed against the foamed resin plate to form a recessed part, then the jig is separated from the foamed resin plate, and then the reinforcing member of the lath body is fitted into the recessed part to form a lath structure. You may make it manufacture a wall body. Alternatively, the recessed portion may be formed at the same time when the foamed resin plate is formed, and then the reinforcing member of the lath body may be fitted into the recessed portion to manufacture the lath structure wall body.

FIG. 23 shows a fifth modification of the one-sided lath structure wall B. In this modified example, as shown in FIG.
A lath net 422 is further fixed on the lath net 421 by welding or the like, and the composite lath net 420 is heat-welded to the foamed resin plate 410. The method of constructing the heat insulating structure using the lath-clad structure wall body B of the fifth modified example is the same as that of the first embodiment. The method of manufacturing the lath structure wall B is the same as in the second modification. Further, the action and effect of the lath structure wall B are almost the same as those of the second modification, but since two lath nets are fixed, the rigidity of the lath structure wall B is further improved by its rigidity. .

In any of the above embodiments, the lath net and the reinforcing member do not have to be made of steel, but may be made of other metal such as aluminum alloy. Further, it may be a resin. In that case, the lath net and the reinforcing member must be made of a material having a higher melting temperature than the foamed resin plate. Further, in each modification, the lath net or lath body is heat-welded to the other side surface of the foamed resin plate, whereby the double-sided lath structure wall body BB can be formed.

Although the lath net or the lath body is subjected to the rust prevention treatment or the waterproof treatment in each of the above-mentioned embodiments, such treatment is not always necessary. Then, in the manufacturing method, the rustproofing treatment or waterproofing treatment was performed in the last step, but the lath net or the lath body may be previously subjected to rustproofing treatment or waterproofing treatment and then heat-sealed to the foamed resin plate. . Further, in the manufacturing method, the step of preheating the lath net or the lath body is preferable for smoothly heating the lath net or the lath body, but it is not an essential step. Similarly, the step of finally forcibly cooling the whole is preferable from the viewpoint of increasing manufacturing efficiency, but this is not an essential step.

Furthermore, in the above-mentioned embodiment of the heat insulating structure and the modified example of the lath structure wall body, the explanation was made on the premise of the planar lath structure wall body, but the heat insulation structure of the present invention has a corner portion (for example, a projected corner). It can also be constructed by using a lathed structure wall body having an L-shaped cross section, such as a structure or a corner structure.

In each of the examples, the lath-tensioned structure wall body in which one surface of the lath net or lath body reinforcing member is heat-welded to the foamed resin plate over almost the entire surface is used, but the entire surface is not necessarily covered with the foamed resin plate. It is not necessary to perform heat welding, and for example, in a lath net, a large number of convex portions may be formed at the required points, and only these convex portions may be heat-welded to the foamed resin plate. You may form many convex parts in a required place and heat-weld a lath net only in the convex part of a 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 heat-welded portion, so that the mortar m enters the gap and is solidified by hugging the lath net, Thereby, the wall strength is improved and the mortar m can be formed thick. Further, although the lath net or lath body is directly arranged on one side of the foamed resin plate, the lath net or lath body is not directly mounted but the side face of the foamed resin plate is coated or the sheet is stretched and then the lath net or lath body is heat-welded. You may do it.

[0038]

As described above, according to the heat insulating structure of claim 1, the heat insulating property of the foamed resin plate can improve the heat retaining property of the underfloor space, and the bonding force between the foamed resin plate and the concrete can be enhanced. In addition, the workability of the heat insulation structure can be improved by making the lath-clad structure wall body in advance, and the self-supporting property of the lath-clad structure wall body does not require a separate formwork. Concrete can be poured and the workability of the heat insulating structure can be further improved.

According to the heat insulating structure of the second aspect, the so-called co-joining action and the narrowing in the vicinity of the opening of the recessed portion due to the tertiary foaming increase the holding strength of the reinforcing member, and also to the gap between the lath net and the foamed resin plate. Since the mortar enters and solidifies by enclosing the lath net, it is possible to increase the bonding force between the foamed resin plate and the concrete.

According to the heat insulating structure of the third aspect, the mortar and the like can be surely attached to the foamed resin plate even on the other side surface of the lath structure wall body.
