Description

  The present invention relates to a wall structure, an outer wall panel used therefor, and a building unit.

  2. Description of the Related Art Conventionally, as an outer wall panel of a building such as a house, one using a ceramic siding material is known. Ceramic siding materials are molded into a plate shape using cementitious raw materials and fibrous raw materials as the main raw materials, cured and hardened, and in addition to being lightweight and inexpensive, easy construction and design It has advantages such as abundantness.

  By the way, ceramic siding materials are easy to cut at factories and construction sites, and have the advantage of excellent processability. Therefore, ceramic siding materials are attached to buildings as outer wall panels as single units. In this case, the destructive resistance against destructive actions such as breaking with a tool is weak, and as a result, the crime prevention performance is lowered.

In this regard, as described in Patent Document 1, if a thin steel plate is integrally fixed to the entire back surface of the ceramic siding material, an effect on the above-described fracture resistance can be expected. However, in this case, the ease of processing, which was an advantage of the ceramic siding material, is impaired, and there is a difficulty in using it as an outer wall panel of a building such as a house.
JP 2004-52477 A

  The main object of the present invention is to provide a wall structure capable of achieving both workability and fracture resistance and an outer wall panel used therefor.

  Hereinafter, means and the like effective for solving the above-described problems will be described while showing functions and effects as necessary. In the following, in order to facilitate understanding, a corresponding configuration example in the embodiment of the invention is appropriately shown in parentheses, etc., but is not limited to the specific configuration shown in parentheses.

  In the wall structure of the present invention, at least one film layer (film layer X) having fracture resistance is provided on the inner side of the outer wall surface material (ceramic siding board 12) forming the outer wall surface. According to this configuration, the film layer improves the fracture resistance of the wall body (outer wall structure 10). For example, when applied as an outer wall structure of a building, intrusion of a suspicious person due to the destruction of the outer wall structure Can be suppressed. Also, in this case, unlike the conventional technique in which a thin metal plate is attached to the entire back surface of the outer wall material for the purpose of improving fracture resistance, the processability of the outer wall material is impaired due to the provision of the film layer. Can be avoided. As a result, a wall structure that achieves both ease of processing and fracture resistance can be realized.

  As a configuration of the outer wall panel (outer wall panel 11), a film material (destructive film 13) may be attached to the back surface (outside surface back surface) of the outer wall surface material, and the film layer may be formed from the film material. In this case, since the outer wall surface material and the film material are integrated, an improvement in fracture resistance of the outer wall surface material can be expected. Therefore, for example, when it is put into practical use as an outer wall of a building, high crime prevention performance can be imparted against intrusion from the outside.

  In particular, a ceramic siding material may be used as the outer wall material, and a film material may be attached to the back surface of the ceramic siding material. In this case, the fracture resistance of the ceramic siding material can be improved without impairing the ease of processing, which is an original advantage in using the ceramic siding material.

  In a wall structure having a frame material (base frame 14) that is integrally fixed to the back side of the outer wall surface material, a film material may be sandwiched and fixed between the outer wall surface material and the frame material. In this case, it is possible to prevent inconvenience that the film material attached to the back surface of the outer wall surface material is peeled off or the attaching position is shifted.

  A gel material may be interposed between the frame material and the film material. As the gel material, for example, an elastic adhesive (such as a modified silicone adhesive) that exhibits viscoelasticity in a cured state is used. By interposing the gel material between the frame material and the film material as described above, a slight relative movement between the frame material and the outer wall surface material becomes possible. Thereby, even if some bending or bending occurs in the frame material, it can follow it. Further, even if the frame material is shaken (vibrated) when an earthquake occurs, it is possible to suppress damage to the outer wall surface material due to the shake.

  A film material may be attached to the entire back surface of the outer wall surface material. Thereby, the whole outer wall surface material is strengthened, and crime prevention performance can be further improved.

  The film material may be attached to the back surface of the outer wall surface material so that a part thereof protrudes from the outer wall surface material, and the protruding portion of the film material may be attached to the back surface of another adjacent outer wall surface material. According to this configuration, when a plurality of outer wall surface materials are arranged side by side in the left, right, top, bottom, etc., they can be installed so as to straddle the film material between adjacent outer wall surface materials (joint portions). Therefore, the film material can be disposed in a gap formed between the outer wall surface materials, and a water stop function and an airtight function can be added in the gap. In this case, the water stop sheet which is an existing technology can be deleted, and simplification of the configuration can be expected.

  In addition, on the back surface of the outer wall surface material forming the quadrilateral, a part of the outer wall surface material protrudes from one end edge portion of the two opposite edge portions, and an unattached portion exists at the other edge portion. The film material may be pasted in such a manner that the protruding portion of the film material is pasted on the unattached portion of another adjacent outer wall surface material. According to this configuration, when a plurality of outer wall materials are installed side by side on the left, right, top, bottom, etc., even if the film material is installed so as to straddle between adjacent outer wall materials, the same film material overlaps and becomes double Can be prevented. Thereby, the problem that a film layer becomes thick locally and the thickness of the wall body becomes non-uniform | heterogenous due to it can be avoided.

  In a wall structure having a frame material (base frame 14) that is integrally fixed to the back surface side of the outer wall surface material, the film material may be attached to a portion that does not overlap with the frame material on the back surface of the outer wall surface material. In this case, the required amount of film material can be reduced and the cost reduction effect can be expected while achieving the effect of obtaining high crime prevention performance. In this case, it is also possible to disperse and affix a plurality of film materials to one outer wall surface material.

  The wall structure of the present invention can be applied to, for example, an exterior enclosure or a veranda fence of a building. In such a case, it is preferable to form the outer wall surface on both the front and back surfaces by providing the outer wall material in a double manner, and to provide the film layer as an intermediate layer of the double outer wall material.

  Moreover, in the wall structure which has an interior material (gypsum board 22) inside an outer wall surface material as a wall body, it is good to affix a film material to an interior material and to form a film layer with the film material. Also in this structure, the destruction resistance with respect to the wall body can be improved as described above.

  Here, as the outer wall panel, before being transported to the construction site (that is, at a factory or the like), it is cut according to the outer wall dimension or the opening dimension in the building or the like with the film material pasted on the outer wall surface material, Furthermore, it is desirable that the frame material is assembled. Thereby, the construction workability | operativity in the construction site which installs a building etc. can be improved.

  In a building unit that constitutes a part of a unit-type building, as described above, an outer wall panel made of an outer wall surface material, a film material, or the like is used, and the outer wall panel is preferably mounted in advance at a factory or the like. Thereby, the construction workability | operativity in the construction site which installs a unit type building can be improved. In addition, stable quality can be ensured.

[First Embodiment]
Hereinafter, an outer wall structure embodying the present invention will be described with reference to the drawings. The outer wall structure of the present embodiment is configured as a partition for indoors and outdoors in a building such as a house. FIG. 1 is a perspective view showing the structure of the outer wall structure 10, FIG. 2 is a sectional view showing the sectional structure of the panel joint in the outer wall structure 10, and FIG. 3 is an exploded perspective view of the outer wall panel 11.

  In the outer wall structure 10 shown in FIG. 1, an outer wall panel 11 is provided on the outdoor side (front side of the drawing), and interior materials such as a heat insulating material 21 and a gypsum board 22 are provided on the indoor side (back side of the drawing). It has been.

  As shown in FIG. 3, the outer wall panel 11 includes a rectangular flat ceramic siding plate 12 for forming the outer wall surface, a fracture resistant film 13 attached to the back surface thereof, and a base frame 14. ing. The ceramic siding plate 12 has, for example, a thickness dimension = 16 mm, a longitudinal dimension = 2825 mm, and a lateral dimension = 990 mm, and a plurality of joint grooves 12a are provided on the surface thereof. However, the size and surface design of the ceramic siding board 12 can be arbitrarily changed.

  The fracture resistant film 13 is a film material having the same vertical and horizontal dimensions as the ceramic siding board 12 and is attached to the entire back surface of the ceramic siding board 12 with an adhesive. The fracture-resistant film 13 is made of a material having flexibility, flexibility, elasticity, and high strength characteristics. For example, a synthetic resin mainly composed of a polyester resin, polyethylene, polyurethane, polyvinyl butyral (PVB), It consists of a synthetic resin whose main component is a resin such as polycarbonate. A plurality of film layers (relatively thin film layers) made of these synthetic resins may be provided, and an adhesive layer may be interposed between these layers.

  As an adhesive used for bonding the fracture resistant film 13 to the ceramic siding board 12, a permanent type adhesive having weather resistance and discoloration resistance is used. It is also possible to attach an adhesive sheet to either the ceramic siding board 12 side or the destructive film 13 side and bond them together using the adhesive sheet.

  The base frame 14 is made of a lightweight steel frame having a U-shaped cross section, and has a vertical frame portion 14a and a horizontal frame portion 14b assembled in a quadrilateral shape with the same vertical and horizontal dimensions as the ceramic siding board 12, and the vertical frame portion 14a and And an intermediate frame portion 14c connected to the inside of the horizontal frame portion 14b.

  And as shown in FIG.1 and FIG.2, as the outer wall panel 11, the destructive film 13 is affixed on the back surface of the ceramics-type siding board 12, and also the destructive film 13 is sandwiched and fixed. A base frame 14 is assembled. In this case, the film layer X is formed of the fracture resistant film 13. Incidentally, the ceramic siding plate 12 and the base frame 14 are joined and fixed by a tapping screw (not shown) or the like, and in that state, the destructive film 13 is interposed therebetween.

  In the outer wall panel 11 having the above-described configuration, the fracture resistance (impact resistance and penetration resistance) is significantly improved as compared with the existing outer wall panel to which the fracture resistant film 13 is not attached. For this reason, deterrence against destructive acts such as “breaking” and “pruning” on the outer wall of the building can be greatly expected. By the way, with regard to crime prevention performance of buildings, a public-private joint conference consisting of the National Police Agency, the Ministry of Land, Infrastructure, Transport and Tourism, the Ministry of Economy, Trade and Industry, and related private organizations is conducting a crime prevention test on building parts. The standard for crime prevention is that it takes more than 5 minutes to intrude in the event of a predetermined destruction. In view of this, the destructive film 13 may be selected so as to satisfy the crime prevention standard.

  In the building, a plurality of outer wall panels 11 are assembled side by side, and as shown in FIG. 2, the base frames 14 (the web surfaces of the vertical frame portions 14a) of the two left and right outer wall panels 11 are arranged. Are joined and fixed to each other by fasteners 16 such as bolts and nuts. In this state, a gap C of about 10 mm is formed between the two left and right outer wall panels 11, and a long water-stop fixed seal 17 made of synthetic rubber is assembled so as to fill the gap C. .

  FIG. 4 shows an enlarged view of the water stop structure at the outer wall panel joint portion (joint portion). Since the water-stop fixed seal 17 is generally used as a water-stop structure for the outer wall of a building, a detailed description is omitted here, but as a general rule, the head 17a exposed to the outdoor side and the head 17a rather than the head 17a. A plurality of lip portions 17b are formed on the inner side and contact the end surface of the ceramic siding plate 12 in an elastically deformed state. Further, a waterproof sheet 18 having a waterproof property is attached to the back side end of the ceramic siding board 12 so as to straddle the left and right ceramic siding boards 12. According to the water stop fixed seal 17 and the water stop sheet 18 described above, intrusion of rainwater or the like from the joint formed between the two left and right ceramic siding boards 12 is prevented.

  Returning to the description of FIG. 2, as a configuration of the outer wall structure 10 on the indoor side with respect to the outer wall panel 11, a wooden brick 23 is assembled to the base frame 14 (vertical frame portion 14 a) of the outer wall panel 11 by a tapping screw or the like. On the indoor side, a wooden frame 24 extending in the vertical direction is assembled with a tapping screw or the like. The gypsum board 22 is assembled to the wooden frame 24 with a tapping screw or the like. In addition, illustration of a tapping screw is omitted here. The heat insulating material 21 is made of glass wool with a moisture-proof layer, for example, and is interposed between the base frame 14 (intermediate frame portion 14 c) of the outer wall panel 11 and the gypsum board 22. An air layer 25 is formed between the ceramic siding board 12 (more precisely, the destructive film 13) and the heat insulating material 21.

  Here, the outer wall panel 11 is manufactured by dividing it into necessary sizes before transporting to the construction site. That is, in a factory or the like, the ceramics siding board 12 is cut and processed in accordance with the outer wall dimensions and opening dimensions of the building with the destructive film 13 attached thereto, and the base frame 14 is assembled. Thereby, the construction workability | operativity in the construction site which installs a building can be improved.

  It is also conceivable to be applied as an outer wall structure in a unit type building constituted by combining a plurality of building units. In this case, as described above, the outer wall panel 11 composed of the ceramic siding plate 12, the destructive film 13 and the base frame 14 is used, and the outer wall panel 11 is mounted on the building unit in advance in a factory or the like. Thereby, the construction workability | operativity in the construction site which installs a unit type building can be improved. In addition, stable quality can be secured as a building unit.

  According to the present embodiment described in detail above, since the destructive film 13 is pasted on the back surface of the ceramic siding board 12 in the outer wall panel 11, the destructive resistance (impact resistance and penetration resistance in the panel 11 is provided. ) Will improve. Therefore, intrusion of a suspicious person due to destruction of the outer wall panel 11 can be suppressed. Also, in this case, unlike the conventional technique in which a metal thin plate is attached to the entire back surface of the ceramic siding plate for the purpose of improving the destruction resistance, the siding plate of the siding plate is caused by attaching the destruction resistant film 13. It can be avoided that the processability is impaired. As a result, an outer wall structure that achieves both ease of processing and fracture resistance can be realized.

  Since the ceramic-based siding board 12 and the fracture-resistant film 13 are integrated by sticking using an adhesive or the like, the fracture-resistant performance of the fracture-resistant film 13 can be exhibited as the fracture-resistant performance of the ceramic-based siding board 12. . Therefore, high crime prevention performance can be imparted against intrusion from outside the building.

  Moreover, since the destructive film 13 is pasted on the entire back surface of the ceramic siding board 12, the entire ceramic siding board 12 is strengthened, and the crime prevention performance can be further enhanced.

  Since the destructive film 13 is sandwiched and fixed between the ceramic siding plate 12 and the base frame 14, it is possible to prevent inconvenience that the destructible film 13 is peeled off or the attaching position is shifted.

[Second Embodiment]
In the first embodiment, the ceramic wall-type siding plate 12 and the fracture-resistant film 13 have the same vertical and horizontal dimensions on the outer wall panel 11 and the fracture-resistant film 13 is pasted without protruding from the ceramic-type siding plate 12. This is changed in the present embodiment. That is, the destructive film 13 is attached to the back surface of the ceramic siding plate 12 so that a part thereof protrudes from the siding plate 12, and the protruding portion of the film 13 is connected to another adjacent ceramic siding plate 12. It is set as the structure affixed on the back surface. Hereinafter, the outer wall structure in the present embodiment will be described focusing on differences from the first embodiment.

  FIG. 5 is a cross-sectional view of the siding plate with film in the present embodiment. Here, the ceramics siding board 12 and the fracture resistant film 13 are basically the same as described above, except that the fracture resistant film 13 is attached to the ceramics siding board 12 in a shifted manner. . Therefore, on the back surface of the ceramics-based siding board 12, an excessive portion (a protruding portion) F1 and an unattached portion F2 of the fracture resistant film 13 are formed. At this time, in the ceramic-based siding plate 12, a film surplus portion F1 is formed at one end portion of the two opposite end portions, and a film non-sticking portion F2 is formed at the other end portion. It will be. In addition, each length dimension L1, L2 of the surplus part F1 and the non-sticking part F2 of the fracture-resistant film 13 is about 20-50 mm. However, L1> L2.

  FIG. 6 is an enlarged cross-sectional view of a main part showing a state (a) before joining the two ceramic industry siding boards 12 and a state (b) after joining at the outer wall panel joining part (joint part).

  As shown in FIGS. 6 (a) and 6 (b), the left and right ceramics siding boards 12 have a film surplus portion F1 on one side (referred to as ceramics siding board 12A) and the other (ceramics siding board 12B). The two siding plates 12A and 12B are joined in a side-by-side state as a pair with the film non-attached portion F2. Particularly in this case, the film surplus portion F1 on the ceramics siding plate 12A side extends to the film non-sticking portion F2 of the ceramics siding plate 12B on the other side and is attached to the non-sticking portion F2. That is, the fracture-resistant film 13 is installed so as to straddle the joint portion between the two siding plates 12A and 12B.

  In this configuration, the film surplus portion F1 on the ceramics siding board 12A side is sandwiched between the ceramics siding board 12B on the other side and the base frame 14 (vertical frame part 14a). Film pasting is performed between the system siding plates 12A and 12B, and then the base frame 14 is assembled to both the siding plates 12A and 12B.

  As described above, according to the second embodiment, since the fracture-resistant film 13 exists in the joint portion between the left and right ceramics siding plates 12A and 12B, the film 13 can add a water stop function and an airtight function. . In this case, since the fracture-resistant film 13 functions as a water-stop sheet, the water-stop sheet 18 (see FIG. 4) at the joint is not necessary, and the configuration can be simplified.

  Moreover, the destructive film 13 is attached to the ceramic siding board 12 so that the film surplus part F1 and the film non-sticking part F2 can be formed, and the film surplus part F1 is attached to another adjacent ceramic siding board 12. Since it was set as the structure affixed on the film non-sticking part F2, even if it installs the destructive film 13 so that adjacent siding boards may be straddled, it can prevent that the film 13 overlaps and becomes double. Thereby, the inconvenience that the destructive film 13 (film layer X) becomes thick locally and the thickness of the outer wall structure 10 becomes nonuniform due to this can be avoided.

  5 and 6 described above, in the ceramic siding board 12, the film surplus portion F1 is formed at one end edge portion, and the film non-sticking portion F2 is formed at the other end edge portion. The film 13 is pasted, but this is changed. For example, as shown to (a) of FIG. 7, the structure which affixes the destruction-resistant film 13 so that the film surplus part F1 may be formed in both edge parts on either side may be sufficient. In this case, the fracture resistant film 13 overlaps and overlaps at the joint where the left and right ceramics siding plates 12 are joined. Thereby, the water-stopping property and airtightness by the fracture-resistant film 13 will improve in the joint part.

  In addition, as shown in FIG. 7 (b), in the ceramic siding board 12, a film surplus portion F1 is formed at one end portion, and an excess or deficiency film 13 is not formed at the other end portion. It is also possible to paste.

[Third Embodiment]
The wall structure of the present invention can be applied to an outer wall or exterior (exterior) of a garage in addition to an outer wall for partitioning the interior and exterior of a building. For example, in the building 30 shown in FIG. 8A, an inner garage 31 is provided on the first floor portion, and an opening / closing member 32 such as a security shutter is provided on the front surface thereof. Moreover, the wall structure 33 for garages is provided in the wall part which partitions the inner garage 31 and the outdoors (hatching part). The wall structure of the present invention is applied to the garage wall structure 33. Alternatively, in FIG. 8B, the wall structure of the present invention is applied to a fence 41 provided around the site including the building 40. In addition, the part which leads to the entrance part 40a of the building 40 in the fence 41 is discontinuous, and the gate 42 is provided in the said part.

  When the present invention is applied to the garage wall structure 33 as described above or the enclosure 41 as an external structure, an interior material is not required unlike the outer wall structure 10 (see FIG. 1 and the like) for partitioning the interior and the exterior. Become. In this case, as the wall structure, for example, the outer wall surfaces may be formed on both the front and rear surfaces by providing double ceramics siding plates, and a film layer may be provided as an intermediate layer of the double ceramics siding plates. FIG. 9 shows a cross-sectional structure of the wall structure used in this embodiment.

  As shown in FIG. 9, the wall structure 50 includes a column member 51 and two outer wall panels 52 and 53 provided with the column member 51 interposed therebetween. The outer wall panels 52 and 53 have the same configuration as that of the outer wall panel 11 described above, a rectangular flat ceramic-type siding plate 54, and a fracture-resistant film (not shown here for convenience) 3) and a base frame 55 made of a lightweight steel frame material. In this case, the base frame 55 of each of the outer wall panels 52 and 53 is fixed to the support material 51, so that both the front and back wall surfaces of the wall structure 50 are configured by the ceramic siding plate 54. ing.

  As described above, according to the third embodiment, by providing the garage wall structure 33 with the film layer having breakage resistance, it is possible to prevent a suspicious person from entering due to destruction of the garage wall. Further, by providing the enclosure 41 with a film layer having breakage resistance, it is possible to prevent a suspicious person from entering due to destruction of the enclosure 41. In any case, crime prevention performance can be improved.

  The wall structure which forms an outer wall surface on both front and back surfaces by providing double ceramic siding boards can be applied to a veranda fence of a building in addition to a garage wall and a fence. In this case, the configuration of FIG. 10 may be employed instead of the configuration of FIG. In the wall structure 60 shown in FIG. 10, two ceramic siding plates 61 and 62 are provided in double so that their respective back surfaces (back surfaces of external appearance) face each other, and a destructive film 63 as an intermediate layer thereof. Is fixed. In this case, sufficient fracture resistance can be realized in the wall structure 60.

[Another embodiment]
The present invention is not limited to the description of the above embodiment, and may be implemented as follows, for example.

  In the outer wall panel, a gel material may be interposed between the fracture resistant film and the base frame. Specifically, in the outer wall panel 11 described in the first embodiment, an elastic adhesive as a gel material is interposed at the joint between the fracture resistant film 13 and the base frame 14. As the elastic adhesive, for example, a modified silicone adhesive based on a modified silicone polymer can be used. Since the modified silicone adhesive has rubber elasticity, it has an effect of dispersing and absorbing internal stress. According to this configuration, some relative movement between the ceramic siding board 12 and the base frame 14 is possible. As a result, even if the base frame 14 is slightly bent or bent, it can follow it. In addition, even if the base frame 14 is shaken (vibrated) when an earthquake occurs, it is possible to suppress damage to the ceramic siding board 12 due to the shake.

  In the said embodiment, although the destructive film was affixed on the whole back surface of the ceramics-type siding board in the state pinched | interposed and fixed with the base frame, this is changed. FIG. 11 is a view of an outer wall panel 71 as another embodiment viewed from the back side. The outer wall panel 71 includes a ceramic siding plate 72 for forming the outer wall surface, a destructive film 73 attached to the back surface thereof, and a base frame 74. Here, the ceramic siding plate 72 and the base frame 74 have the same configuration as that of the above-described embodiment (the ceramic siding plate 12 and the base frame 14), and only the fracture resistant film 73 is different. In this case, the fracture-resistant film 73 is attached to the back surface of the ceramic siding plate 72 in three separate portions that do not overlap with the base frame 74. According to this structure, while exhibiting the effect that high crime prevention performance is obtained, the required amount of the destructive film 73 can be reduced, and a cost reduction effect can also be expected.

  As shown in FIG. 12, the destructive film 13 may be adhered to the gypsum board 22 in addition to the destructible film 13 being adhered to the back surface of the ceramic siding board 12. In this case, a fracture resistant film 75 is provided between the heat insulating material 21 and the gypsum board 22, and the film layer X is formed by the fracture resistant film 75. According to this configuration, the fracture resistance of the outer wall structure 10 can be further improved. In addition, the structure which affixes the destruction-resistant film 75 only on the gypsum board 22 may not be affixed on the back surface side of the ceramic siding board 12. In short, it is only necessary that at least one film layer (film layer X) having fracture resistance is provided inside the outer wall surface material (ceramic siding board 12).

  Although the said embodiment demonstrated the example which arranges several outer wall surface materials (ceramics-type siding board 12 grade | etc.) In a horizontal direction, these several outer wall surface materials (ceramics type | system | group siding board 12 grade | etc.) Are arranged in an up-down direction. There may be.

  As the outer wall surface material, an outer wall material other than the ceramic siding material can be used. For example, a ceramic outer wall material or a ceramic plate outer wall material may be used, and a ceramic siding material may be attached to the back surface of these outer wall materials.
