Description

  The present invention relates to a construction method for constructing a surface portion such as a wall, a floor, a roof, or a ceiling of a building by using a precast-type building material mainly formed of plaster as a long material in advance.

  Stucco, which has been used as a wall finishing material in Japanese architecture since ancient times, has a pathological pathology that does not generate volatile organic compounds (VOC) that cause sick house syndrome, as well as its attractive appearance. In recent years, not only building walls and exterior walls, but also indoor walls and ceilings have excellent functions such as high safety and humidity control that absorbs and releases moisture in the air to stabilize indoor humidity. Application to the surface is also being studied.

  On the other hand, plaster is a paste-like composition formed by kneading aggregates such as water and sand into slaked lime, and after kneading, it combines with carbon dioxide in the air, and curing starts from the surface by this gas curing reaction. Because of this property, when trying to form a stucco wall or the like, it is necessary to perform a stucco kneading operation at the construction site, and the work must be completed before the drying proceeds to some extent. The speed of drying of the plaster can be adjusted by mixing the paste, but drying is also affected by the water absorption of the base, so sufficient experience is necessary for the adjustment. Since painting requires plastering by skilled craftsmen, it is a material that is difficult to use from the viewpoint of labor costs and construction period. For this reason, it has been considered difficult to apply plaster to the walls and floors of buildings, while paying attention to the excellent aesthetics and functionality described above.

  In contrast, Patent Document 1 discloses a building soil composition in which a stucco composition obtained by previously kneading quicklime, water, aggregate, and the like is hermetically stored in a non-breathable bag. According to this building soil composition, manufacturing, material, and construction costs can be reduced.

  Patent Document 2 discloses an architectural plaster board formed by applying plaster to the surface of a fiber-based board whose surface has been subjected to alkali treatment. According to this building stucco board, plaster is pre-applied to the fiber-based board, so it is possible to save the trouble of on-site application at the construction site, etc., compared to the case of on-site application at the construction site, etc. It is explained as an effect that quality control can be sufficiently performed.

  Further, Patent Document 3 discloses a coated uncured stucco sheet that is a plaster-coated wall-forming building material in which the exposed surface of the uncured stucco-processed sheet is adhered to the plaster-coated wall surface. According to this plaster sheet, in addition to the difficulty and complexity of painting over a large area with the conventional "trowel", the problem of reduction in painting engineers is solved, and the plaster painting work is simplified. The explanation to be made.

  Japanese Patent Laid-Open No. 2004-162406   JP 2007-170126 A   JP 2007-154653 A

  With the thing of patent document 1, although there exists an advantage that a stucco composition can be preserve | saved for a long time and it is not necessary to knead on the spot, the plaster work by manual work is required like before in the case of the painting to a wall etc. Therefore, labor costs and construction costs cannot be improved.

  Moreover, in the thing of patent document 2 and patent document 3, when it applies to the wall surface etc. of a building, a plaster is only a thin layer and is formed in planar shape, The base part is made of wood or concrete. Since it is configured, it is possible to obtain the aesthetics of a plastered wall from the exterior, but it is not possible to enjoy excellent functions such as humidity control and heat insulation characteristic of an old plastered wall. The plaster wall that has been used in Japan since ancient times has a structure in which the surface of the earth wall that is the foundation is relatively thinly plastered, and the thick earth wall and the plaster combine to provide an excellent function. It has been demonstrated, and its unique function cannot be sufficiently exerted only with a thin layered or plate-like plaster.

  This invention is to construct a surface structure such as a wall surface, a floor surface, a ceiling surface, and a roof surface of a building in a short period of time and at a low cost without using skill by using a building material mainly composed of plaster. , Enabling the surface structure to provide necessary and sufficient strength by itself, making the surface structure fully exhibit the characteristics such as humidity control of plaster, and excellent environment from construction material production to disposal The purpose is to obtain performance.

  According to a first aspect of the present invention, a fixed plaster building material formed by forming an outer casing made of plaster in an aspect surrounding the core material over substantially the entire length of the rod-shaped core material is used as a reference plane of the building (of the building Many surfaces are arranged in parallel along the wall, floor surface, ceiling surface, roof surface, and the surface that serves as the construction standard for the part of the surface structure such as the sleeve wall outside the building, the blindfold wall, and the fence. It is the surface construction method of the building characterized by this.

  According to a second aspect of the present invention, in the first aspect, a pair of shaft members (columns, studs, foundations, beams, trunk differences, picture frames, guide rails, etc.) located at both ends of the reference surface. And the like.) A large number of the above-mentioned fixed stucco building materials are arranged between the respective stucco building materials, and the respective building materials are connected to each other through fasteners in through holes provided so as to penetrate each fixed stucco building material. This is a surface construction method for objects.

  According to a third aspect of the present invention, in the first aspect, an engaging portion is formed along the longitudinal direction on one or both of the opposing end surfaces of the pair of shaft members positioned at both ends of the reference surface. And it is the surface construction method of the building characterized by engaging the edge part of the said fixed stucco building material with this engagement part, and holding many fixed stucco building materials between the said shaft members.

  A fourth aspect of the invention according to claim 4 is applied to the surface construction method, characterized in that an outer shell portion made of plaster is formed over a substantially entire length of the rod-shaped core material so as to surround the core material. It is a standard plaster building material.

  According to a fifth aspect of the present invention, in the outer shell portion of the fourth aspect of the present invention, a convex portion is formed on one side surface, and a concave portion having a shape that fits the convex portion on a side surface opposite to the one side surface. , Each is a fixed stucco building material formed.

  6th invention which concerns on Claim 6 is a fixed stucco building material in which the plaster in the said 4th invention contains slaked lime, water, and the cut waste cloth as the composition.

  A seventh invention according to claim 7 is a fixed stucco building material characterized in that a sheet material is applied to the surface of the outer shell portion of the fourth invention to prevent damage to the outer shell surface. is there.

  According to an eighth aspect of the present invention, by pouring the kneaded plaster into a formwork in which the rod-shaped core material is previously positioned, and releasing the mold after the plaster is cured, the core is stretched over substantially the entire length of the rod-shaped core material. It is a manufacturing method of the fixed stucco building material applied to the said surface construction method characterized by forming the outer shell part which consists of stucco in the aspect surrounding a material.

According to the above inventions, the following effects can be obtained.
According to each of the first to third inventions, by arranging a large number of fixed stucco building materials having a structure in which a core material capable of providing a strength burden is previously coated with stucco along the reference plane of the building, Since the surface structure such as the floor is constructed, there is no need for skilled plastering or additional work such as finishing with a ceiling board, etc. can get. Therefore, in constructing the surface structure of the building, the construction period can be shortened and the labor cost can be reduced, and the construction cost can be surely reduced. Further, since the dried and solidified fixed stucco building material is assembled, drying shrinkage between the assembled members does not occur, and a building that is easy to manage and highly accurate is obtained. Furthermore, since high rigidity and high strength can be ensured by the core material of each fixed plaster building material, it is possible to impart sufficient earthquake resistance to the building without providing reinforcing members such as braces. In addition, according to the surface construction method according to the present invention, it is possible to reduce the weight of the building compared to the concrete structure, so that in addition to being able to build the pile foundation easily and inexpensively, the cost depreciation period is short, so the point of fixed asset tax But it is advantageous.

  According to 2nd invention, since it is the structure which connected each fixed stucco building material mutually through fasteners, such as a penetration material and a bolt which penetrated the through-hole, the joint strength between each fixed stucco building material is shown. Since it can improve and can position many regular stucco building materials along a reference plane via a fastener, the workability | operativity at the time of construction improves.

  According to the third invention, an engaging portion is formed along the longitudinal direction of the shaft member, and an end portion of the fixed stucco building material is fitted to the engaging portion to hold a large number of the fixed stucco building materials. Therefore, the fixed stucco building material can be held at the shaft material part to improve the strength as a surface structure, and each fixed stucco building material can be positioned by coupling with the engaging part on the shaft material, so workability when constructing Will improve.

  According to each of the fourth to seventh inventions, the fixed stucco building material to be applied to the construction method has a configuration in which an outer casing made of stucco is formed over the substantially entire length of the rod-shaped core material so as to surround the core material. From the above, the volume of the stucco can be sufficiently secured by the outer shell, and therefore when using this to construct a surface structure such as a wall, the humidity control, sound absorption, heat insulation, fire resistance, Excellent functions such as fungicide and VOC adsorption can be sufficiently exhibited.

  In addition, because of the dry shrinkage force of the plaster that forms the outer shell, a strong adhesion occurs between the core material and the plaster, so that it does not easily peel off or crack from the surface of the plaster, and has excellent durability. Stucco building materials and surface structures are obtained.

  Moreover, the external shape and intensity | strength required for the fixed-shaped plaster building material which concerns on this invention according to a use can be freely set according to the material, shape, and dimension of a core material. Therefore, for example, even if the outer dimensions are the same, those applied to the floor surface can ensure the necessary strength and rigidity as the floor surface by applying a thick wooden core material or metal core material, etc. It is possible to apply a core material with relatively low strength and rigidity to those applied to the wall surface and ceiling surface. In this case, increase the volume ratio of the stucco in the regular stucco building material, and adjust the humidity control properties described above, etc. It becomes possible to further improve various performances.

  Furthermore, the fixed stucco building material according to the present invention has an excellent workability that the outer shell part is made of plaster, so that the outer shape can be easily processed and corrected. The size and shape can be easily adjusted using a light tool such as a power tool. Moreover, since this fixed stucco building material has plaster as a main component, it is lightweight as a building material and is easy to handle, such as being portable by human power. Furthermore, since the fixed stucco building material according to the present invention is basically composed of wood or metal material which becomes plaster and core material, it is possible to recycle all remaining materials during construction and demolition materials during dismantling, wood, plaster For composting, composting is also possible.

  According to the fixed plaster building material in which the convex portion is formed on one side surface of the outer shell portion and the concave portion having a shape that fits the convex portion is formed on the opposite side surface as in the fifth invention. Since fixed stucco building materials can be arranged based on the fitting between the convex and concave portions, positioning of a large number of fixed stucco building materials at the time of construction becomes easy, and the strength and airtightness of the joints of the fixed stucco building materials are improved. Can be increased.

  As in the case of the sixth invention, as the composition of the stucco that forms the outer shell portion, when including slaked lime, water, and cut waste cloth, waste cloth that is generally incinerated can be effectively used. The emission of carbon dioxide accompanying the incineration can be suppressed. Moreover, since the plaster takes in carbon dioxide and is air-cured, the regular plaster building material according to the present invention exhibits excellent environmental performance from the viewpoint of fixing the amount of carbon dioxide in the atmosphere.

  As in the seventh invention, by sticking a sheet material to the outer shell, it is possible to reliably prevent breakage such as cracks and chipping from the surface of the outer plaster made of plaster, and to increase its durability. it can.

  According to the eighth invention, the kneaded plaster is poured into a formwork in which the rod-shaped core material is previously positioned, and the mold material is released after the plaster is cured, thereby enclosing the core material over substantially the entire length of the rod-shaped core material. Since the outer casing made of plaster is formed in such a manner, it is possible to mass-produce regular plaster building materials by molding, thereby further reducing the manufacturing cost and promoting the reduction of the construction cost.

  Hereinafter, some embodiments of the present invention will be described with reference to the drawings. In the drawings, parts corresponding to each other are denoted by the same reference numerals.

  1 and 2 each show an embodiment in which the surface construction method according to the present invention is applied to construction of a wall surface of a building by a wooden frame construction method. In the figure, 1 is the foundation of a building, 2 to 4 are shaft members, and 11 is a fixed stucco building material. The shaft members 2 to 4 are respectively formed from wooden squares as the foundations, columns, and beams (or trunk differences) of the building, and in this case, the inner and outer end surfaces serve as the reference surfaces of the walls to be constructed.

  The fixed stucco building material 11 is a square-shaped building material formed to a standard dimension within a range of 900 to 3000 mm long, for example, so as to fit between the shaft members, and corresponds to the standard dimension as shown in FIG. An outer shell portion 13 made of a stucco composition is formed so as to surround the core material 12 having a length of approximately the entire length. In this case, as the core material 12, for example, a thinned material processed into a round bar shape is applied, and the outer shell portion 13 is formed around the periphery so as to have a square cross section. As a cross-sectional dimension, for example, the core material 12 has a diameter of 60 to 120 mm, and the outer flange portion 13 has a square of about 90 to 150 mm. The details of the material and manufacturing method of the fixed stucco building material 11 will be described later.

  The feature of this surface construction method is that, as shown in FIG. 1, a large number of fixed stucco building materials 11 are arranged in parallel between a pair of shaft members 3 and 3 that become pillars, or As shown in FIG. 2, between the pair of shaft members 2 and 4 serving as a base and a beam, a large number of fixed stucco building materials 11 are arranged in a laminated state in parallel with them. Thereby, the wall surface which uses plaster as a main component material can be constructed | assembled for a short time, without requiring plastering between each shaft material.

  The coupling structure between the shaft members 2 to 4 and the fixed plaster building material 11 or the bonding structure between the fixed plaster building materials 11 is arbitrary, but preferably has a configuration as shown in FIG. 4 or FIG. FIG. 4 shows a pair of shaft members 3 provided with through holes 14 for passing fasteners such as penetrating members 6 or bolts 7 made of wooden squares so as to cross the shaft member 3 and each fixed stucco building material 11 (see FIG. 3). , 3, each fixed stucco building material 11 is fixed via the fastener. FIG. 5 shows that a groove 8 as an engaging portion is formed along the longitudinal direction on one or both of the opposing end surfaces of the pair of shaft members 3, 3, 2, 4. 11 end portions are fitted to hold a large number of fixed stucco building materials 11 between the shaft members. In this case, for example, as shown in FIG. 6, a protrusion 16 is provided at the end of the fixed plaster building material 11, and the protrusion 16 is fitted into the groove 8. The protrusion 16 may be formed integrally with the end of the core member 12 or may be attached as a separate member to the end of the fixed stucco building material 11.

  According to the embodiment shown in FIG. 1 or 2, a strong surface structure can be obtained in which one or both surfaces of the wall are finished as they are without requiring additional work such as plastering and finishing that require skill. Therefore, the construction period of the building can be shortened and the labor cost can be reduced, and the construction cost can be surely reduced. Moreover, since the fixed plaster building material 11 shape | molded previously to the standard dimension is assembled, the drying shrinkage between the members after an assembly does not occur, but a management is easy and a highly accurate building is obtained. Furthermore, since high rigidity and high strength can be ensured by the core material 12 included in each fixed stucco building material 11, it is possible to impart sufficient earthquake resistance to the building without providing reinforcing members such as braces. .

  Moreover, by applying the coupling structure as shown in FIG. 4, the bonding strength between the respective fixed stucco building materials 11 can be improved, and a large number of the fixed stucco building materials 11 can be easily positioned along the reference plane of the wall by the fasteners. Therefore, workability at the time of construction can be improved. Alternatively, by applying a joint structure as shown in FIG. 5, the fixed stucco building material 11 can be held at the shaft member portion to improve the strength as a surface structure, and each fixed stucco is combined with the groove 8 on the shaft member. Since the building material 11 can be positioned, workability during construction can be improved. Of course, the combined structure of FIG. 4 and FIG. 5 can be used together, whereby the strength and rigidity of the fixed stucco building material 11 can be further improved. In the embodiment of FIG. 5, for example, an L-shaped material or the like may be used as the engaging portion instead of the groove 8, and the standing portion of the L-shaped material attached along the longitudinal direction of the shaft material is a fixed plaster building material By engaging with the end of 11 in an engaging manner, the same effect as the engagement structure by the groove can be exhibited.

  FIG. 7 is a third embodiment relating to a method for constructing a plaster wall. This is an example in which the shaft member 3 in FIG. 1 is configured by a fixed plaster building material 11A in which a square member having a necessary and sufficient strength as a pillar is used as a core member 12 and an outer flange portion 13 made of relatively thin plaster is formed around the shaft member 3. It is. By configuring the wall surface as the fixed stucco building material 11A as the shaft material 3 itself in this way, the entire interior and exterior surfaces including the pillars and corners of the building are configured with the stucco surface together with the fixed stucco building material 11 arranged between the shaft materials. Thus, a more aesthetic appearance can be obtained.

  FIG. 8 is a fourth embodiment relating to a method for constructing a plaster wall. In this construction method, a large number of fixed stucco building materials 11 and 11B are arranged on both the inside and outside of the reference surface, respectively, and the inside space is filled with stucco using the fixed stucco building materials 11 and 11B as a mold to dry and solidify Thus, a large-area plaster wall 20 is formed inside the fixed plaster building materials 11 and 11B. Since the fixed stucco building materials 11 and 11B functioning as a formwork have air permeability, drying and solidification of the filled stucco proceeds rapidly, and the stucco wall 20 can be constructed in a short period of time. According to this embodiment, the wall surface can be constructed in a dry state, and after drying, the internal and external fixed stucco building materials 11 and 11B and the stucco wall 20 are integrated, and the stucco wall 20 is integrated, Buildings with high rigidity, airtightness, sound insulation, soundproofing, vibration proofing and fire resistance can be constructed. In addition, the fixed stucco building materials 11 and 11B and the stucco wall 20 can provide higher humidity control. In constructing the plaster wall 20, instead of using the regular plaster building material 11B as a formwork, a sheet-like material having water permeability and breathability such as a wire mesh or a resin mesh may be applied, thereby making it easier. The plaster wall 20 can be constructed.

  In addition, although each said embodiment demonstrated the surface construction method concerning this invention as an example when constructing the wall of a building, this invention is not restricted to a wall, For construction of a floor, a ceiling, and a roof surface It goes without saying that is also applicable. Further, the present invention can be applied to a steel structure, and is not limited to a shaft-structured building, but can be constructed as a schoolhouse structure by assembling each fixed stucco building material 11 into a cross-beam shape. Moreover, in the embodiment shown in FIG. 1 or FIG. 2, not only the fixed stucco building material 11 but also other fixed materials such as wood are interposed between the shaft members alternately or intermittently with the fixed stucco building material 11. However, it is possible to give the surface structure a unique expression.

  Next, the fixed stucco building material applied to the surface construction method will be described. The fixed stucco building material 11 according to the present invention is basically a rod-shaped or columnar building material in which an outer casing 13 made of plaster is formed so as to surround the core material 12 as shown in FIG. . First, an example of the manufacturing method will be described with reference to FIG. In the figure, reference numeral 21 denotes a long mold having an L-shaped cross section, and two molds 21 are opposedly combined to form a square cross-section mold as shown in FIG. Both ends of the mold are closed with caps 22 as shown in the drawing (b), and the kneaded plaster from the gate 23 provided on one cap 22 is poured and dried and solidified. The cap 22 is provided with a recess 24 for holding the core material 12 at the center, and the core material 12 is cast by pouring plaster in a state where the core material 12 is held in advance between the two caps 22. Then, the outer flange portion 13 made of plaster is formed around it. When the plaster has solidified to some extent, the mold composed of the mold 21 and the cap 22 is opened, and the workpiece to be the standard plaster building material 11 is released as shown in FIG. The shaped plaster building material 11 thus obtained is deburred, surface-finished, and dimension-adjusted as necessary to obtain a product. The length of the mold 21 may be longer than a required dimension of the fixed stucco building material 11, and a plurality of the fixed stucco building materials 11 may be obtained by cutting the workpiece into a predetermined length after releasing the mold. In order to promote drying and solidification at the time of casting, it is desirable to form the mold 21 from a material having water permeability and air permeability such as a mesh material or a sintered metal material.

  Thus, since the fixed stucco building material 11 according to the present invention can be mass-produced as a so-called precast material by molding by casting, it can be produced at a low cost, which greatly reduces the construction cost. Contribute. In addition, by forming irregularities of the pattern on the inner surface of the mold, it is possible to represent an arbitrary pattern in a relief shape on the surface of the finished fixed plaster building material 11, so that a highly decorative surface structure can be easily obtained. it can. For example, as the pattern by the unevenness, a pattern suitable for interior and exterior of a building, such as a highly artistic pattern equivalent to a maki-e, or a pattern imitating a grain, can be freely represented. Moreover, it can also color by knead | mixing a pigment beforehand to a plaster before pouring into a casting_mold | template, and the fixed-form plaster building material 11 which has various external appearances according to a use and a request | requirement can be obtained.

  On the other hand, the fixed stucco building material 11 formed in this way has an outer shell portion 13 based on a configuration in which an outer flange portion 13 made of plaster is formed over the substantially entire length of the rod-shaped core material 12 so as to surround the core material 12. The volume of the plaster can be sufficiently secured by this, and therefore, when a surface structure such as a wall is constructed using this, humidity control, sound absorption, heat insulation, fire resistance, fungicidal properties, VOC, characteristic of the plaster Excellent functions such as adsorptivity can be exhibited sufficiently.

  Moreover, since a strong adhesion force is generated between the core material and the plaster based on the drying shrinkage force of the plaster constituting the outer shell portion 13, peeling and cracking from the surface of the plaster hardly occur, and an excellent mechanical strength. And durability.

  Moreover, the fixed stucco building material 11 which concerns on this invention can set freely the external shape and intensity | strength required according to a use according to the material of the core material 12, a shape, and a dimension. Therefore, for example, even if the outer dimensions are the same, those applied to the floor surface can ensure the necessary strength and rigidity as the floor surface by applying a thick wood or metal material as the core material 12, It is possible to apply the core material 12 having a relatively small diameter or low strength / rigidity to those applied to the wall surface. In this case, the volume ratio of the stucco in the fixed stucco building material 11 is increased, and the humidity control property described above is applied. It becomes possible to further improve various performances.

  Furthermore, since the outer shell 13 is made of plaster, the fixed plaster building material 11 according to the present invention has excellent workability such that the outer shape and dimensions can be easily processed and corrected. The size and shape can be easily adjusted at the site using light tools such as scissors and electric tools. Moreover, since this fixed stucco building material 11 has plaster as a main component, it is lightweight as a building material and is easy to handle, such as being portable by human power. Furthermore, since the fixed stucco building material 11 according to the present invention is basically composed of wood or metal material that becomes plaster and a core material, it is possible to recycle all remaining materials during construction and demolition materials during dismantling, For plaster, composting is also possible.

  The fixed stucco building material 11 according to the present invention has a high degree of freedom in selecting the core material 12 as described above. For example, as the core material 12, when applying a wooden core material formed from a thinned material to a rod shape, The manufacturing cost of the fixed stucco building material 11 can be reduced while effectively using the thinned wood. Alternatively, as the core material 12, a metal core material made of a long metal material such as a mold steel or a steel pipe may be applied. In this case, a higher strength requirement can be met, and a hollow steel tube or the like can be used. When the material is applied, it is possible to secure an air layer to improve the heat insulation performance, or to use the hollow portion as a ventilation passage. In addition, when not so strong, a resin pipe may be used instead of the steel pipe. Regardless of which material is applied as the core material 12, the plaster forming the outer shell portion 13 has a good familiarity with each material, and is firmly adhered to the core material 12 by drying shrinkage and exhibits high strength and durability.

  On the other hand, the composition of the stucco that forms the outer shell portion 13 is basically slaked lime, water, bamboo grass (plant fiber), etc., but by kneading the waste cloth cut as a reinforcing material, The strength can be improved and the effect of reducing the amount of carbon dioxide in the atmosphere can be expected. That is, this fixed stucco building material 11 can effectively use waste cloth that is generally incinerated, and can suppress emission of carbon dioxide accompanying the incineration. In addition, the plaster takes in carbon dioxide and cures by air, and therefore exhibits excellent environmental performance from the viewpoint of fixing the amount of carbon dioxide in the atmosphere.

  Furthermore, by applying a sheet material made of paper or cloth to the outer shell surface of the fixed stucco building material 11 via an adhesive such as stucco, the surface strength is increased and damage such as cracks and chips is more reliably ensured. Can be prevented.

  The above-described fixed plaster building material 11 has a square cross section or a rectangular cross section, but is not limited thereto, and various shapes can be imparted. Some examples are shown below.

  In FIG. 10, a convex portion 17 is formed on one side surface of the outer shell portion 13, and a concave portion 18 having a shape fitting with the convex portion 17 is formed on the side surface opposite to the outer shell portion 13 along the longitudinal direction of the fixed plaster building material 11. (See (a) of the figure). According to this fixed stucco building material 11, adjacent fixed stucco building materials 11 can be arranged in a connected state based on the fitting of the convex portions 17 and the concave portions 18 (see (b) in the figure), so While positioning of many fixed stucco building materials 11 becomes easy, the intensity | strength, rigidity, and airtightness of the junction part of the fixed stucco building materials 11 can be improved. In addition, the said convex part 17 or the recessed part 18 is good also as a level | step difference shape which notched the corner | angular part of the outer shell part 13. FIG.

  FIG. 11 shows a structure in which grooves 19 are formed along the longitudinal direction at both ends of a fixed stucco building material 11 having a circular cross-sectional shape (see (a) in the figure). This fixed stucco building material 11 is fitted with a connecting member 31 made of square material or the like between the adjacent grooves 19, 19 of adjacent ones (see (b) in the figure), and connected to each other via this connecting member 31. By setting it in a state, as in the case of FIG. 10, positioning of a large number of fixed stucco building materials 11 at the time of construction can be facilitated, and the strength and airtightness of the joined portions of the fixed stucco building materials 11 can be increased.

  In addition, when casting the fixed stucco building material 11, when using a material in which waste cloth is kneaded with stucco, the viscosity is higher than that in which kneaded paper or the like, so as shown in FIG. The plaster is poured into a box-shaped mold 21 that is opened as a gate, and the inner plaster is pressed by a lid 25 that closes the opening to dry and solidify while dehydrating from the top and bottom or the side of the mold 21. .

  As mentioned above, although several embodiment regarding this invention was described, it cannot be overemphasized that this invention is not limited to the content of these embodiment, and can take a various form in the range which does not deviate from the summary.
