It relates to goods and belongs to the field of reinforced concrete construction.

2. Description of the Related Art [External insulation method] As a conventional external insulation method, for example, as shown in FIG. A ventilation layer type that provides a ventilation layer between the exterior material and the heat insulating material to prevent functional deterioration due to wetting of the heat insulation material and to prevent the temperature of the exterior material from rising.
(B). A type in which the exterior material and the heat insulating material are in close contact with each other, and in which the heat insulating composite panel is mounted (C). A closed air layer type in which a closed air layer is provided between the exterior material and the heat insulating material, (d). A typical construction method is a double-wall type in which the exterior material of each other construction method is doubled to form a double-wall structure.

In the above conventional method, the ventilation layer type of (a) can use either a regular shape material or an irregular shape material as a heat insulating material, but it is necessary to take measures for fire prevention, and also as an exterior material. Since a PC plate, metal panel, masonry, etc. are used, the cost is high. Further, the dry contact type (b) has a lower cost than other construction methods, but has a problem that dew condensation (condensation on the boundary surface) occurs between the exterior material and the heat insulating material. Also, (C)
In the closed air layer type, the air layer functions as a heat insulating layer, but there is a problem that internal dew condensation occurs.

[Outer heat insulating composite panel] In FIG.
In the external heat insulation composite panel used in the dry contact type (b) or the closed air layer type (c), a cement board (GRC type) made of cement mortar and alkali glass fiber as an exterior material, Main materials are fire-proof materials (ceramic siding), volcanic debris and fly ash, which are molded, cured and hardened into a plate shape using cement, calcareous materials, siliceous materials, glass fibers, slag, gypsum, perlite, etc. A fire-proof material (GFPC type) and the like, in which alkali-resistant glass fiber is used as a reinforcing material and hardened with a phenol resin, is typically adopted.

FIG. 16 (B) is an explanatory view of forming an outer wall using the contact type composite panel of (b) above, which is a cement board P.
Outer insulation composite panel P0 in which a'and the heat insulation layer Pb are integrated
Is used as an outer mold, and wall reinforcing bars are arranged between the inner mold plywood 7a and the inner surface of the composite panel P0.
Wide end 16b, Separator 9, KP Con 10, Shaft 1
1, a foam tie 12, a rib washer 13, a nut 14, a heat insulating anchor 27, and the like are used as a wall-type framework for concrete placement to form an outer heat insulating outer wall in which the outer composite panel P0 and the concrete wall are integrated. .

[Reinforced concrete wall structure] FIG.
FIG. 3 is a schematic perspective view of a conventional reinforced concrete wall type structure as a four-story apartment house, in which the outer wall and the inner wall of the building are integrated by wall beams WL and beam beams by reinforced concrete casting. In the concrete frame, a load bearing wall W that supports a vertical load (vertical load) such as a building's own weight or a load and a horizontal load such as seismic force, and a non-bearing wall W0 above and below an opening R1 such as a window frame are located in various places. Have a wall-type structure in which the required reference wall amount of the bearing wall W is satisfied.

[0007]

Although it is common knowledge in the industry that an external heat insulating building is a building that can prevent dew condensation, is healthy, energy-saving, and has high durability, it is more common than an internal insulating building. Since the cost is high, the cost factor has been an obstacle to the spread. Among the external heat insulation methods, the dry method using the composite panel in which (b) (Fig. 16 (A)) is closely attached to the exterior material and the heat insulation material is relatively low in cost, but the exterior material and the heat insulation material are relatively inexpensive. There is a problem that dew condensation occurs on the boundary surface between and.

Also, various conventional composite panels such as GRC type, ceramic siding, and GFPC type in which the exterior material and the heat insulating material are in close contact with each other are used integrally with the concrete skeleton, and the exterior material itself is thin. , Has problems such as frost resistance. Also, extruded cement board (EC
P) has a bending strength of about 5 times that of concrete, a compressive strength of about 2 times that of concrete, and a water absorption rate of 16
%, The ECP plate is excellent in frost damage resistance and can be used as it is as a base material on the outside, but since it is heavy, conventionally, it is usually used alone as an exterior material.

Further, in the reinforced concrete wall type structure of FIG. 17, it is necessary to arrange the load bearing walls in a well-balanced manner to smoothly transfer the load of the upper floor to the foundation, so that a large space cannot be created. Therefore, for example, it is impossible to use a building such as a rental condominium that also serves as a store together. In addition, there are many walls such as boundaries and partitions, and the concrete formwork is complicated and labor-intensive.Moreover, due to the restrictions of many concrete partition walls, there is no flexibility in the floor plan of the building, and there are considerable restrictions in use. Was there.

Further, in order to make the wall continuous as a reinforced concrete structure, for example, the wall of the opening R1 such as a window frame must be made of reinforced concrete even though it becomes a non-bearing wall W0 that cannot be used as a wall amount. In addition to the complicated concrete mold assembly around the section R1, the presence of concrete in the non-bearing wall W0 also increases the weight of the building, increasing the load on the foundation, and embedding the building (foundation civil engineering work).
The burden was increasing.

Further, when the non-bearing wall W0 is used as a space, for example, even if the mortar is applied by finishing with a concrete block made of a dissimilar material, the appearance is unsatisfactory, and a problem such as cracking occurs in the mating portion. The wall cost of the wall W0 could not be reduced. Furthermore, if the span of the floor slab is long, the thickness of the floor slab will also be large, the amount of reinforcing bars used will increase to support the weight of the building, and a beam will have to be provided, so that the beam will become a living space. Prominently deteriorates the availability of the living room.

The present invention studies the problems inherent in the conventional external heat insulating building and the means for solving them, from the individual viewpoints such as the external heat insulating method surface, the exterior material surface, and the reinforced concrete wall structure surface. Various problems on the panel surface, heat insulation method surface, and wall type structure surface were improved and developed as interrelated technology as a building, and various problems in conventional external heat insulation building were solved at once. It is intended to provide a revolutionary reinforced concrete exterior heat insulating building with high durability and capable of reducing building cost.

[0013]

[Means and Actions for Solving the Problems] For example, FIG.
As shown in FIGS. 2 and 5, the outer cement plates Pa, Pa ′
A reinforced concrete wall type structure having an outer wall composed of a book wall Rw part and a load bearing wall W part using outer heat insulating dry contact type composite panels P and P0 in which the inner and inner heat insulating layers Pb are integrated. The wall Rw is an outer wall formed by stretching only the composite panel P, and the load-bearing wall W is a reinforced concrete wall Wc of the load-bearing wall W using the composite panel P0 as a concrete casting outer formwork.
To form an outer wall, and the outer surface of the composite panel P of the book wall Rw part and the outer surface of the composite panel P0 of the load bearing wall W part are flush with each other to provide a reinforced concrete external heat insulating building (claim 1).

The "book wall Rw portion" is a wall of the outer wall other than the load bearing wall W portion, and as is apparent from FIGS. 1 and 2, the structural design such as the upper and lower wall portions of the window frame. It is a wall portion that cannot be calculated as an upper bearing wall, and is a portion of the outer wall of the concrete frame other than the bearing wall W portion. In addition, "cement board",
Extruded cement board (ECP) or cement board composed of cement mortar and alkali glass fiber (GRCP)
Etc., including various cement boards, "heat insulation layer",
It means a wide range of materials that can be laminated and integrated as a heat insulating material on a cement board, including synthetic resin foamed heat insulating material layers such as extruded polystyrene foam and rigid foamed urethane foam.

The "extension of only the composite panel P" is to form the outer wall only by stretching the opening of the wall surface where the concrete wall Wc does not exist, and the composite panel P is a concrete frame. It suffices that the composite panel is attached to the opening so as to have a function as an outer wall, and the structure and the attachment structure of the composite panel are not limited. Of course, the composite panel P used as the book wall has a strength that the panel itself can endure as an outer wall. In addition, the "outer heat insulation close contact type" refers to a type in which the cement plate and the heat insulation layer are in dry contact, as described as the heat insulation method (b) type in the description of the prior art, and includes the wet close contact type. Absent.

The building obtained by the above-mentioned solution means is a wall type structure, but in the case of a wall Rw portion, that is, a wall portion other than the load bearing wall that cannot be included in the wall amount as a load bearing wall, a concrete wall Since there is no such thing, it is possible to omit the reinforcing bar arrangement, formwork and concrete placing on the non-bearing walls such as the upper and lower parts of the window frame, reduce the amount of construction, and reduce the amount of materials used, which makes the building lighter and lighter. It is possible to reduce the cost of rooting (earthwork) due to the introduction of materials, and to rationalize the materials used, the amount of construction, and the number of construction days. As a result, a significant reduction in construction costs can be achieved.

Further, the book wall panel P and the bearing wall panel P0
Since the outer surfaces are flush with each other, the exterior of the outer wall, the waist drainer and the rainwater drainer can be easily arranged, and the presence of the book wall is not conspicuous and has a uniform appearance. In addition, the load-bearing wall W is formed by using an inexpensive dry contact type composite panel, and in combination with forming the book wall only between the load-bearing walls W, only the composite panel is used to form the entire outer peripheral wall. Since external heat insulation can be achieved, cost reduction can be achieved in terms of materials used for the outer peripheral wall and construction costs. Therefore, energy saving is achieved by external insulation, and mold and mite generation in the living room can be prevented by preventing dew condensation, and cracking due to heat stress on the concrete wall and neutralization of concrete can be suppressed, providing a comfortable living environment with excellent durability. Environmental buildings can be obtained at low cost.

Further, the cement board P of the composite panel P of the book wall
a and a cement plate Pa 'of the composite panel P0 of the load bearing wall, both of which are ventilation layers a1 and a2 for allowing air from the outside to flow vertically
Is preferably provided (Claim 2). In this case, it is an inexpensive dry contact-type composite panel, and although the cement board has a higher moisture permeability resistance than the heat insulation layer, the cement board has a ventilation layer. Condensation on the boundary surface between a certain heat insulation layer and the cement board can be completely prevented, condensation prevention by external heat insulation can be further achieved, and mold and mite generation due to condensation on the wall and deterioration of the building are also possible.
It can be suppressed for a long time. Moreover, the cement plate itself as an exterior material also has improved durability because the influence of heat stress (heat stress) is suppressed to a minimum by the ventilation layer, and the joint sealing and the exterior coating film due to the heat stress of the cement plate itself. Deterioration can be prevented, and in combination with the fact that the outer surface of the outer wall is flush, the freedom of finishing (tiling and painting) the exterior material (cement board) can be guaranteed.

Further, the composite panel P of the book wall Rw and the bearing wall W
It is preferable that the heat insulation layer Pb has the same thickness T2 as that of the composite panel P0, and the cement plate thickness T1 of the book wall composite panel P is larger than the cement plate thickness T1 ′ of the load bearing wall composite panel P0 (claim). Item 3). Since the load-bearing wall composite panel P0 needs only the function of the outer form of the concrete wall, the conventional composite panel P0 in which the cement plate Pa ′ has a thin thickness T1 ′
However, since the book wall panel P needs to have an outer wall function by itself, it is necessary to select a thick cement plate Pa such as the patent No. 2999980 panel developed by the applicant. Therefore, by adopting a relatively low-cost thin composite panel P0 for the load bearing wall W, rationalization of the construction cost can be achieved, and at the same time, an outer wall exhibiting uniform outer heat insulation performance of the load bearing wall W portion and the book wall Rw portion can be obtained. can get.

Further, the concrete wall thickness Wt of the bearing wall W portion
Is made thicker than the design standard wall thickness Ts of the reinforced concrete wall structure, and the water cement ratio of 55 is added to the concrete wall Wc.
%, A slump value of 12 cm, and a concrete having a nominal strength of 24 N / mm ² are preferably used (claim 4). The "design standard wall thickness Ts" is a wall thickness specified by the Japanese Architectural Institute of Japan's wall reinforced concrete construction calculation standard, and is a numerical value that determines the height of the building and the bearing wall thickness for each floor.

Therefore, according to the design standard of the reinforced concrete wall structure, the specified strength of the concrete used is 18 N / mm.
² Reduction of the allowable wall amount by using concrete with a strength higher than (general), and the proof wall thickness Wt is the reference wall thickness Ts.
By reducing the allowable wall amount due to the larger size, the horizontal length (wall amount) of the load bearing wall W can be further reduced, the large opening R can be set in a wide range, and the load bearing wall W has sufficient strength. The amount of formwork used for placing the concrete wall Wc can be further reduced, and the construction cost can be further reduced.

In the concrete skeleton CB, the floor slab S has a beamless floor flat plate structure and has a tube structure in which a wall is arranged on the outside of the floor slab S, and the steel columns 30 are provided at appropriate positions between the floor slabs S. Are arranged in a pin joint structure,
It is preferable to use a floor slab in which the column rows are present in two directions at right angles (Claim 5).

Therefore, the concrete skeleton CB is a combination of the wall type structure and the flat plate structure, and since the two-way slab transfers the horizontal and vertical loads to the floor slab to the outer wall of the tube structure, no beam is required. In addition, since the flat plate does not have a bearing wall such as a beam that separates the floor slab, the workability of formwork construction, rebar construction, and interior is improved, and the construction cost of reinforced concrete external insulation building can be reduced. . Moreover, the degree of freedom in floor plan design is improved, and the floor plan can be freely changed during the period of use of the building. Since each of the columns 30 has a pin-jointed structure and does not receive a horizontal force, it can be a column having a small cross section, which is advantageous for effective use of the floor space.

The large opening R including the opening R1 such as the window frame Wf and the opening side surface Rs existing on the side of the opening R1 has a cement plate Pa having a through hole a1 and a synthetic resin foam heat insulating layer P.
A composite panel P in which b and the interior material Pc are integrally laminated is stretched to form a book wall Rw portion (claim 6). "Integrated"
Means a structure in which the respective constituent materials are integrated as the composite panel B, and a cement board, a synthetic resin foam heat insulating layer, and an already formed three member of the interior material, which are integrated by interposing an adhesive, It also includes one in which a foamable synthetic resin is injected and foamed between the cement plate and the interior material (cavity) and the three members are integrated by the foaming solidification adhesive force of the synthetic resin (Patent No. 2999980 panel).

Therefore, as shown in FIG. 3, the large opening R is
The non-bearing wall portion of the conventional reinforced concrete wall structure shown in FIG. 17, that is, the opening portion R1, becomes much wider,
Since the number of reinforced concrete walls is much smaller, the amount of reinforcing steel, concrete, formwork, etc. used can be reduced, the amount of formwork construction can be reduced, and the number of construction days can be shortened, resulting in a significant reduction in construction costs. I can achieve it. Moreover, since the composite panel also includes the interior material Pc, the interior material P
It is possible to use c as a finishing material as it is or to use it as an interior base material, and it is possible to save labor in the interior finishing.

Further, the book wall Rw portion has an extrusion-molded cement board Pa having a large number of juxtaposed through holes a1 therein, and an upper frame 5a made of an angle steel material fixed to the inner surface of the cement board,
A mounting bracket in which a composite panel P including a frame body including a lower frame 5b and side frames 5c, a synthetic resin foam heat insulating layer Pb arranged in the frame body, and an interior material Pc is fixed to a front end portion of a floor slab S. It is preferable that the upper frame 5a and the lower frame 5b are fixedly attached to and tensioned to the frames 3 and 4 (claim 7). The “arrangement” of the synthetic resin foam heat insulating layer includes a synthetic resin filled and foamed and integrated, and an extruded heat insulating plate integrated with an adhesive.

The composite panel is typically described in Patent No. 299.
A composite panel P of No. 9980, in which an extrusion-molded cement board has a bending strength of about 5 times and a compressive strength of about 2 times that of concrete, and the upper and lower frames of the composite panel and both vertical frames are angle steel materials. Since the composite panel P alone has a sufficient outer wall strength, the composite panel P can be easily formed by simply fixing the composite panel P to the floor slab via the mounting brackets 3 and 4. The interior finishing of the wall Rw can be labor-saving.

Further, the left and right connecting portions J of the book wall Rw and the bearing wall W are connected.
In x, it is preferable that the heat insulating materials 2b and 2b 'be abutted and intervened on all side surfaces of the heat insulating layer Pb of the book wall composite panel P and the heat insulating layer Pb of the load bearing wall composite panel P0 (claim 8). As shown in FIG. 10, since the outer surfaces of the book wall composite panel P and the load bearing wall composite panel P0 are arranged flush with each other, the heat insulating layer Pb of the two panels P, P0 is not provided in the heat insulation layer Pb of the left and right connection parts Jx of the two panels P, P0. Although there is a step in the front-rear direction, due to the presence of the heat insulating materials 2b and 2b ', the steel frame body (upper frame 5a, lower frame 5b,
The contact between the side frame 5c) and the cast concrete wall Wc of the bearing wall W can be prevented, and the cold bridge action can be prevented. Then, the inner end of the cement board Pa of the composite panel P and the concrete wall W
Since the distance between the outer ends of c is also widened due to the presence of the heat insulating materials 2b and 2b ', it is possible to suppress the deterioration of the outer heat insulating function of the outer wall at the left and right connecting portions Jx between the book wall panel P and the load bearing wall panel P0.

Between the upper and lower load bearing wall composite panels P0, a perforated backer 24 'for ensuring vertical communication of the air flow is interposed between the upper and lower groove grooves a2, and the backer 24 is also provided.
It is preferable that ′ be projected above the through hole a1 of the book wall composite panel P, and the groove 24 and the through hole a1 are in air communication with each other by the notch 24c on the upper surface and / or the lower surface of the backer 24 ′. 9). The perforated backer 24 'may be of any form as long as it supports the sealing 25 to be packed between the upper and lower panels inside and ensures the vertical communication of the air in the groove a2. Only the honeycomb-shaped backer 24' as shown in FIG. Instead, it is also possible to form a large number of through-holes in the vertical direction in the conventional square backer having a cross section to form a perforated backer.

The notch 24c is a backer 24 'in which the upper and lower surfaces of the backer 24' are in contact with the end surfaces of the upper and lower panels.
Since the airflow in the left-right direction is possible along the upper surface or the lower surface, the notch 24c may have a shape other than the V-shaped cut as in the embodiment (FIG. 11). Although the groove a2 of the load bearing wall panel P0 is shallow, the air conduction amount is relatively small, but the perforated backer 24 'is provided with the notch 24c and extends over the through hole a1 of the book wall panel P, so that the through hole a1. The air flow F2 in the groove a2 is sucked into the large-capacity air flow F1 (see FIG. 15), and the air permeability in the load bearing wall panel P0 is improved.

Further, it is preferable that the book wall composite panel P is stretched so that the panel lower end surface Be is located at a position lower than the floor slab upper surface Sf by the small step d1 (claim 10). The lower end surface Be of the upper composite panel P and the upper end surface Bt of the lower composite panel P
The space is filled and closed by the ceiling 25 due to the outer wall finish, but in this case, even if the rainwater enters from the space between the upper and lower panels P due to deterioration of the ceiling, the small step d1 acts as a water repellent, and therefore the floor slab. It is possible to prevent rainwater from entering the upper surface Sf.

As shown in FIG. 10, the left and right connecting portions of the load bearing wall composite panel P0 are connected to each other by the joint line Lb of the heat insulating layers Pb.
Is preferably shifted from the contact seam line La between the cement plates Pa ′ and abutted against the inner surface of one cement plate Pa ′ to be integrated with the concrete wall Wc (claim 11).
When forming the bearing wall W, the pressure of the cast concrete acts on the inner surface of the composite panel P0 serving as the outer form, and concrete water leaks out from the joint line Lb of the heat insulating layer Pb. Layer seam line Lb is cement board Pa '
Since it is in contact with the inner surface, leakage of concrete water into the joint between the cement plates Pa ′ can be suppressed. Therefore, the cleaning work of the cement plate Pa 'before the joint finish of the outer wall can be greatly streamlined.

FIG. 15 is a diagram showing a relational structure between the book wall panel P and the load bearing wall panel P0 on the first floor and the foundation structure 1. The foundation structure 1 has a linear shape, and the heat insulating material 2 arranged on the outer surface of the concrete foundation structure 1 also has the respective panels P, P0.
It has the same thickness as the heat insulating layer Pb and is extended linearly. Therefore, the panel P having the cement board Pa having a large thickness T1 (60 mm) and the panel P0 having the cement board Pa ′ having a small thickness T1 ′ (25 mm) are arranged so that their outer surfaces are flush with each other. In this case, the book wall panel P is arranged as in the embodiment (FIG. 6), and as shown in FIG.
When the a and the panel heat insulating layer Pb are vertically communicated with each other, the load bearing wall panel P0 is as shown in FIG. 15 (B).
Although the heat insulating material 2 and the panel heat insulating layer Pb are displaced from each other in the front and rear direction, the presence of the heat insulating material 2a interposed can suppress the deterioration of the heat insulating function. In addition, the heat insulating material 2 on the outer surface of the substructure 1
Is protected by lath mortar 42.

The outer surfaces of the thick panel P and the thin panel P0 are flush with each other as shown in FIG.
The heat insulating material 2, the heat insulating material 2a, and the heat insulating layer Pb may be vertically connected to each other, and the stretched wall panel P may be arranged so as to be shifted inward as shown in FIG. Since the book wall panel P and the load bearing wall panel P0 are arranged such that the outer surfaces of the cement plates Pa and Pa ′ are flush with each other, the waist drainer 40 uses the mounting piece 41 to pass the load bearing wall W portion and the book wall Rw portion. It can be installed in the same shape, and the head tree 50 (FIG. 1) can also be arranged in the same appearance through the entire outer wall. Therefore, from the air hole O4 of the waist drain 40 to the stretched wall panel P
Even though the composite panel P and P0 having different thicknesses are used in parallel, the external air conduction structure through the through hole a1 and the groove a2 of the load-bearing wall panel P0 does not impair the appearance and is simple. Can be formed into

[Outer Insulated Building Obtained] The reinforced concrete outer insulated building obtained in the embodiment example is a reinforced concrete wall type four-story building, with 2LDK8 units on both sides at a total of 480 m ^{2 on} both sides in the middle staircase. When the present invention (FIG. 3) and the conventional example (FIG. 17) were compared in terms of the amount of concrete, formwork, and reinforcing bar used in the building of FIG.
It was as follows. (Table 1) Concrete amount (m ³ ) Form amount (m ² ) Reinforcing bar amount (ton) Conventional example 284 1930 29.5 Invention 218 1187 19.8 Contrast (invention reduction%) 24.2% 38.5 % 23.9% or more, the cost of the building of the present invention is more than 30 % lower than that of the conventional building of the same scale even under the simple comparison in terms of materials used.

Moreover, the weight (concrete, rebar, steel frame) of the building in the above comparative example is 682.7 tons for the conventional building and 521.9 tons for the building of the present invention, which is 23% of the present invention.
Can be lightened. Furthermore, the present invention can reduce the amount of use and the amount of construction in the formwork because there is no beam, partition small wall, or complicated mold work around the four corners of the window frame. The ratio of the bar is large and the deformed steel bar with a large diameter is not used.Because there is no beam, there are few troublesome things such as ribs and the floor slab muscles do not have bending muscles. Assembly costs can be reduced.

In the building of the present invention, the weight of the building can be reduced to reduce the cost of foundation work, the total number of structures is small, the slab of the formwork is flat and the wall is small, and Since the workability of assembling is good, the construction period can be shortened, and by using the book wall composite panel P in the opening of the wall, it is possible to save labor such as applying a light-weight partition substrate and spraying a heat insulating material. Also, the construction cost can be reduced. That is, the building of the present invention is actually
It is possible to reduce the cost even more than the cost reduction of more than 30% from the viewpoint of the material that can be calculated in design.

The concrete of the present invention has a water-cement ratio of 55%, which is higher than the water-cement ratio of conventional (normal) concrete of 65%. Absorbs gas, calcium hydroxide in concrete changes to calcium,
As a result, when the alkalinity is lost), when the concrete covering thickness on the reinforcing bar is 4 cm, the water-cement ratio is 6%.
With 5% (conventional product), 68 years, with 55% water cement ratio (invention), 142 years. With 3 cm concrete cover (standard), 65% water cement ratio with 38 years, 55% water cement ratio with 80 years. Becomes

Further, according to the present invention, the concrete skeleton itself has high durability, and since the entire outer surface of the concrete skeleton is protected by external heat insulation, the neutralization promoting factor due to dew condensation on the concrete wall is removed. The neutralization of skeleton concrete is also longer than the nominal neutralization period value (JASS5, reinforced concrete construction, Architectural Institute of Japan), and the concrete skeleton protected by external heat insulation also has heat stress which is a factor of cracking. Since it is a heat insulating layer having a thickness of 75 mm, it can be suppressed to about 1/25 of that of the inner heat insulating layer, and the building of the present invention becomes a highly durable building.

In the building of the present invention, the floor is a beamless floor and is 15
A flat plate with a thickness of cm or more (18 cm on the X1 side and 15 cm on the X2 side in Fig. 3) has a tube structure, and pillars 3 on the floor slab.
Since 0 is also a pin joint type and is a two-way slab of a steel column with a small cross section, the floor slab S has sufficient strength as a tube structure building and also has a sound insulation function on the upper and lower floors, and the space above the floor slab S is small. It can be used effectively,
There is a high degree of freedom in the floor plan, and the floor plan can be freely changed during the period when the room is used. In addition, the height between each floor slab can be set relatively low because there are no beams, etc., and a 4-story condominium can be constructed even under the 10m height regulation, and the rental condominium will have high business efficiency. . Therefore, as a middle- and low-rise building with five or less floors, it will be an epoch-making, highly practical outer insulation building in terms of construction cost, usability, and habitability.

Further, since the entire outer peripheral wall of the building is formed by the composite panels P and P0 as factory-produced products, an outer heat insulating wall having the function as designed at the time of manufacturing can be obtained, and in terms of construction,
The load bearing wall W portion can be stretched together with the formation of the concrete formwork, and even in the book wall Rw portion, it is a relatively simple work of fixing the upper and lower frames of the composite panel P by the mounting brackets 3 and 4, and the concrete loading of the load bearing wall W is performed. At the same time, it can be installed reasonably. In addition, since each composite panel P, P0 has a ventilation layer, it contributes to the improvement of the durability of the building by the dew condensation prevention function, and also suppresses the heat stress of the concrete skeleton and the cement board of the panel to the outer wall surface. It also guarantees the degree of freedom and durability such as exterior coating.

Moreover, since the outer surface of the book wall Rw portion is also flush with the load bearing wall portion W, the waist drainer 40 and the headstock 50 can be easily attached and finished with good appearance. Therefore, not only the expensive thick composite panel P is used only for the book wall Rw portion, the cost can be reduced by reducing the amount of building materials, the construction is easy, and the construction is durable. In terms of design, the building is far more advantageous than the conventional external heat insulation building.

Further, according to the above-mentioned embodiment, the book wall composite panel P is mounted by inserting and locking the mounting hole H1 of the lower frame 5b into the connecting pin 6 of the mounting bracket firmly fixed to the floor slab S. Work is easy because it is temporarily fixed. Further, the mounting position of the first-floor book wall panel P has a definite meaning in the construction of the outer wall of the book wall, but in order to mount the mounting plate 4b engaged with the lower frame 5b on the plate receiver 3'while adjusting the front and rear and the left and right. ,
The first-floor book wall panel P can be mounted flush with the load-bearing wall panel P0 and can be accurately mounted under necessary fine adjustments such as uneven adjustment.
Therefore, even if the book wall panels on the upper floors are successively laid on the basis of the arrangement of the first-floor book wall panels P, the load-bearing wall panel P0 and the outer surface are flush with each other and can be erected cleanly. A book wall Rw can be formed. Of course, the first-floor slab S including the foundation structure 1 is of high quality and the first-floor slab S of the mounting bracket is of high quality.
If it is accurately fixed to the floor slab, the same mounting bracket 4 as shown in FIG. 13A for other floors can be used as the panel mounting bracket for the first floor slab.

At the stage of temporarily fixing the book wall panel P,
Insulation material 2a, 2b, sealing rubber 21 between the panels in order
Since such materials are attached, the work of coping with heat insulation and waterproofness of the outer wall can be reasonably performed. Also, since the tree 20 is used when fixing the mounting bracket 4, it is possible to mount the mounting bracket 4 at an appropriate position and prevent the inflow of concrete, and it is preferable to fill the on-site foamed urethane foam in the post-finishing of the mounting bracket 4 portion. Can be implemented. Then, by using the formwork plywood 7b at the time of assembling the mounting bracket 4 with the floor slab S formwork, the lower end surface Be of each book wall panel P is set to the floor slab top surface Sf.
It can be installed below d1 (11 mm), and rainwater can be completely prevented from entering the floor slab S from the lower end surface Be of the book wall panel.

Even in the bearing wall W portion, each panel P
The seam line Lb between the heat insulation layers at the collision edge of 0 is the cement board Pa
Since it is shifted from the seam line between ', it is possible to prevent leakage contamination from the seam line La of the cement plate Pa' of the wall concrete, and to reduce the burden of finishing cleaning work of the outer wall cement plate Pa 'in the subsequent process. Further, since the perforated backer 24 'of the groove a2 of the load bearing wall panel P0 is projected above the through hole a1 of the book wall panel P, the through hole a1 having a large air flow rate has a shallow groove a2.
The airflow between the load bearing wall panels P0 is improved.

Even at the boundary between the load bearing wall W portion and the book wall Rw portion, the load bearing wall concrete is applied to the side frame 5c of the book wall panel P.
Since it abuts against the heat insulating material 2b adhered to the side surface and concrete is placed in a superposed form, the cold bridge action between the L-shaped steel side frame 5c and the concrete wall Wc can be prevented by the heat insulating material 2b, and the heat insulating function It becomes an excellent outer wall.

[Others] FIG. 8C shows a book wall composite panel P.
The upper and lower surfaces of the heat insulating material 2a to be interposed between the upper and lower heat insulating layers Pb at the upper and lower connecting portions Jy and the sealing rubber 21 attached to the front end thereof are covered with a plastic fireproof sheet (product name: FIBLOCK) 27. , Each composite panel P, P0
Insulation 2 interposed between the upper and lower connecting parts Jy and Yx
If a fire resistant sheet 27 is applied to the abutting interface between a and 2b and used, the fire prevention performance in the event of a fire is improved.

In forming the load bearing wall form M1 (FIG. 1), the formwork plywood 7s is placed in contact with the interior material (gypsum board) Pc of the stretched wall panel P and placed in concrete to form the book wall panel. If the inner surface of the heat insulating material 2b between P and the load bearing wall panel P0 is also covered with the concrete wall Wc, it is advantageous in preventing damage to the heat insulating material 2b due to the dismantling of the load bearing wall form M1, and
It is also possible to prevent the heat insulating material 2b from being burned in the event of a fire.
Further, in the embodiment example, the honeycomb-shaped perforated backer 2 is provided.
4'is provided on the entire length of the groove a2 of the load bearing wall panel P0, but even if they are partially scattered, the groove a2 of the load bearing wall panel P0 is provided.
To the through hole a1 of the book wall panel P may be arranged over the entire length.

EFFECTS OF THE INVENTION Although the structure is a reinforced concrete wall type structure, all the reinforced concrete walls (non-bearing walls W0 in FIG. 17) that cannot be included in the bearing walls of the outer peripheral wall are used as book walls made of factory production panels. It is possible to reduce the amount of frame used and shorten the construction period.
Part and the outer wall of the book wall Rw part are all formed of a factory-produced composite panel, so it is easy to add a uniform external heat insulation function.
And can be achieved reasonably.

Moreover, the cost of even the basic civil engineering work accompanying the weight reduction of the building itself can be reduced by reducing the use amount of concrete, reinforcing bars, etc., and the wall type structure has a large space for utilizing the living room without pillars to project the living space. However, it is possible to provide a highly practical building which is epoch-making in the construction industry at a low construction cost and in a short period of time, as compared with the conventional external heat insulating building having a wall structure.

In the composite panels P and P0 used as the bearing wall W and the book wall Rw, the cement plate on the outside is the ventilation layer a.
1, a2 are provided to prevent dew condensation of the building and to suppress heat stress of the composite panels P, P0 and the concrete skeleton CB, thereby realizing high durability of the building and the outer surface of the load bearing wall W portion and book wall Rw portion. Combined with the fact that it is flat, the liberalization of the exterior of the outer wall surface is guaranteed, and the building will be excellent in design.

Moreover, the book wall panel P and the bearing wall panel P0
Since the outer surfaces are flush with each other, it is easy to arrange waist drainers and rain drainers (Kasaki), and it is possible to finish them with good appearance. In terms of appearance, mixing of the book wall Rw and the bearing wall W is also possible. It is unobtrusive and is the same as a conventional reinforced concrete building.

Moreover, since the concrete skeleton has a wall type structure and a flat slab tube structure, and the columns on the floor slab have a pin joint structure and a small cross-section column,
Liberalization of living layout and change of layout has been realized, and since there are no beams in the living room, the height between floor slab top and bottom can be relatively low, and there are many floors even under certain height restrictions. The building can be constructed, the usage efficiency is good, and the building with good habitability can be obtained.
