In an outer wall of a building in which a recess formed between and is used as a joint 2, conventionally, a convex portion 13 formed at an intermediate portion in the thickness direction of one end of one wall panel 1 has a wall on the other side. Panel 1
Has a structure in which it is fitted in a concave portion 14 formed in the middle portion in the thickness direction of the other end portion thereof, and the plate-like packing 3 is interposed in the fitted portion. 14
The bottom surface 14a and the end surface 13a of the convex portion 13 are pressed against each other.

Further, the wall panel 1 has the following structure in order to improve its heat insulation and fire resistance. That is, the wall panel 1 has a metal surface material 15 and a back surface material 16 which are formed by subjecting a steel plate to various processes such as bending, and a heat insulating material 17 loaded in an internal space surrounded by them. At the same time, the surface material 15 and the back surface material 16 are separated from each other in the middle portion of the convex portion 13 in the thickness direction and the middle portion of the concave portion 14. In addition, 4 is a base material.

On the other hand, the front surface material 15 and the rear surface material 16 of the wall panel 1 are formed in symmetrical shapes, and the end surfaces 11, 11 on the front surface side (outdoor side) and the rear surface side (rear surface side) of the one wall panel 1 and the other The end faces 12 and 12 on the front surface side and the back surface side of the wall panel 1 were set to the same level in the arrangement direction of the one wall panel and the other wall panel. Therefore, the wall panels 1, 1 are
When connected as shown in the drawing, the width A'of the joint 2 (hereinafter referred to as joint width) A'is the same on the front surface side and the back surface side.

In the connection structure in which the joint width A'is the same on the front surface side and the back surface side, if the joint width A'on the front surface side is widened to change the design and appearance formed by the wall panel 1, Along with this, the joint width A'on the back surface side is also expanded to the same width as the joint width A'on the front surface side.

[Problems to be solved by the device]

However, according to the conventional connecting structure in which the joint width A'on the front surface side also expands to the same width as the joint width A'on the back surface side, when the joint width A'on the front surface side is widened, the joint 2 The thickness of the wall panel 1 in the portion is only the thickness of the convex portion 13, and is thinner than the thickness of the wall panel 1 in the other portion by the depth of the joints 2, 2 on the front and back sides. However, there was a problem that the heat insulation performance and fire protection performance of the product deteriorated.

The present invention has been made in view of the above situation,
You can change the appearance and design of the entire wall by selecting two kinds of joint widths facing the outer surface, wide and narrow, while suppressing the deterioration of heat insulation performance and fire prevention performance at the joints. It is an object of the present invention to provide a connection structure for a heat insulating wall panel that can exhibit excellent sealing properties even when it is invaded.

[Means for Solving the Problems] In order to achieve the above object, the heat insulating wall connecting structure according to the present invention has one end of one heat insulating wall panel among heat insulating wall panels whose ends face each other. In the middle portion of the thickness direction of the, the tip portion is projected a pair of convex portions spaced apart from each other in the thickness direction and a recess located between the pair of convex portions, and the other heat insulating wall panel A pair of concave portions fitted to the pair of convex portions and a protrusion portion located between the pair of concave portions are formed in the middle portion in the thickness direction of the other end portion. In a connection structure of heat insulating wall panels, in which a convex portion is fitted into a pair of concave portions of the other heat insulating wall panel to form wide concave joints on the front surface side and the back surface side between both heat insulating wall panels. , The fitting of the pair of convex portions and the pair of concave portions The packing is interposed between the parts, and the recess formed between the surface of the packing that covers the protrusion formed between the pair of recesses of the other heat insulating wall panel and the pair of protrusions of the one heat insulating wall panel. A space passage is formed between the heat insulating wall panel and the bottom surface of the heat insulating wall panel, and at least one of the heat insulating wall panels on one side or the other side of the heat insulating wall panel is made to protrude from the end surface on the front side of the heat insulating wall panel. The width of the recessed joint on the front surface side is made wider than the width of the recessed joint on the back surface side.

[Operation] According to the present invention, the width of the recessed joints on the front surface side between the adjacent heat insulation wall panels is made wider than the width of the recessed joints on the rear surface side, and the joints on the front and back surfaces are inside and outside. Although the appearance and design of the entire wall can be changed to two types by reversing the construction, the part of the insulation panel on one side has a protruding end face with the thickness of the wall panel protruding at the joint part on the wide side. Since the thickness is increased as a whole, it is possible to suppress deterioration of heat insulation performance and fire prevention performance even if any of the joints of the front surface and the back surface having different widths faces the outer surface.

Moreover, by interposing packing between the fitting portions of the pair of convex portions and the pair of concave portions, it is possible to secure the shielding function that prevents the fire from flowing through the gap between the adjacent heat insulating wall panels. Not only is it possible to prevent rainwater from entering the interior, and even if some rainwater may enter due to capillary action, etc. The heat insulation wall panel is formed between the bottom surface of the recess formed between the pair of convex portions and is transferred into the space passage that is in a decompressed state with respect to the outside, and is dropped when the wall panel is vertically attached sizing, When the wall panel is laterally sizing, it is possible to secure an excellent sealing property such that a slight slope is given to allow the wall panel to smoothly flow down the slope and prevent further intrusion into the interior.

〔Example〕

FIG. 1A shows a connection structure of heat insulating wall panels according to an embodiment of the present invention.

The illustrated two heat insulating wall panels 5 and 5 have the same structure, and one end and the other end of these heat insulating wall panels 5 and 5 are connected to each other.

The heat insulating wall panel 5 is one in which a heat insulating material 53 is loaded in an internal space surrounded by a front surface material 51 and a back surface material 52 which are arranged to face each other. The surface material 51 is made by bending a metal plate such as a color steel plate or stainless steel, but the back surface material 52 is not limited to those metal plates and may be made of a synthetic resin plate or a wooden plate. . In addition to the synthetic resin foam, the heat insulating material 53 may be a known heat insulating material such as glass wool or a fire resistant heat insulating material. When a synthetic resin foam is used for the heat insulating material 53, the front surface material 51 and the back surface material 52 are used in advance in a state in which the gap between the facing surface material 51 and the back surface material 52, which are arranged opposite to each other, is closed by the blocking materials 54, 54. The insulating wall panel 5 is easily manufactured by foaming the synthetic resin filled in the enclosed internal space by a known means. At that time, it is desirable to use a synthetic resin having self-adhesiveness with respect to the surface material 51 and the back surface material 52,
When such a synthetic resin is used, not only the front surface material 51 and the back surface material 52 are integrated by the heat insulating material 53, but also the heat insulating material 53 formed by the synthetic resin foam layer obtained by foaming the same.
Does not easily peel off from the front surface material 51 and the back surface material 52, and the desired heat insulating property and fire resistance of the heat insulating material 53 are reliably maintained for a long period of time.

A convex portion 55 is formed in the middle portion in the thickness direction of one end of the heat insulating wall panel 5.
Is projected. The convex portion 55 in the figure is a pair of convex portions 55 ', 55' whose front end portions except the root portion are spaced from each other.
It is divided into In this way, when the tip side portion of the convex portion 55 is divided into a pair of convex portions 55 ', 55', the pair of convex portions 5 '
A recess 56 is inevitably formed between the 5'and 55 ', and the front surface and the back surface of the heat insulating wall panel 5 and a pair of convex portions 55', 55 '.
One end surfaces 5a, 5a 'of the heat insulating wall panel 5 are inevitably located in the stepped portion between and. Of these one end surfaces 5a, 5a ', the one end surface 5a' on the back surface side is set at a position protruding from the one end surface 5a on the front surface side. Also, this heat insulation wall panel 5
At one end of the above, the facing portion of the front surface material 51 and the back surface material 52 is set in the above-mentioned recess 56, and the sealing material 54, 54 that closes the gap between them is made of aluminum foil or the like fire resistance or water resistance. Excellent material can be used.

A recess 58 is formed in the middle portion in the thickness direction of the other end of the heat insulating wall panel 5.
Are formed. The recess 58 in the figure is divided into a pair of recesses 58 ', 58' spaced apart from each other. Thus the recess 5
When 8 is divided into a pair of recesses 58 ', 58', a protrusion 59 is inevitably formed between the pair of recesses 58 ', 58'. Moreover, at the other end of the heat insulation wall panel 5,
The facing portion of the front surface material 51 and the back surface material 52 is set in the protrusion 59, and a material excellent in water resistance such as aluminum foil is used for the closing members 54, 54 for closing the gap between them. . Five
b and 5b 'indicate the other end surfaces on the front surface side and the back surface side of the heat insulating wall panel 5, and the other end surfaces 5b and 5b' are set at the same level in the arrangement direction of the one wall panel and the other wall panel. In FIG. 1A, reference numeral 10 indicates a fastener such as a bolt that fixes the other end of the other heat insulating wall panel 5 to the base material 4.

In the two heat insulating wall panels 5, 5 connected to each other,
The pair of convex portions 55 ', 55' of one heat insulating wall panel 5 are individually fitted into the pair of concave portions 58 ', 58' of the other heat insulating wall panel 5. The plate-like packing 7 is arranged over the end surface (including the blocking member 54) of the projecting portion 59 and the fitting portion of the convex portion 55 'and the concave portion 58'. As shown in an enlarged view in FIG. 1B, the plate-like packing 7 includes the end surface 55a of the convex portion 55 and the inner and outer surfaces 55b, 55b in the fitting portion.
And the bottom surface 58a of the concave portion 58 and both side surfaces 58b, 58b thereof are pressed against each other. In addition, the surface 71 of the plate-like packing 7 that covers the end surface of the protrusion 59 and the bottom surface of the recess 56 (blocking member).
Including 54. ) And a space passage 8 through which water flows are formed. Furthermore, one end surface 5a, 5 of the heat insulating wall panel 5 on one side
a'and the other end surface 5b of the other heat insulating wall panel 5 facing the a ',
The recesses formed between the joints 5b 'and 5b' are joints 9,9 ', and the joint width A on the front surface side of the joints 9,9' is wider than the joint width a on the back surface side. .

According to the above connecting structure, since the joint width A on the front surface side is wider than the joint width a on the back surface side, the design and appearance of the joint width A on the front surface side are wide. However, the fireproof performance and the heat insulating performance are affected by the joint width a on the back surface side. That is, the thickness of the heat insulating wall panels 5 and 5 in the joint portion 9 on the front surface side is partial, but there is a root portion of one heat insulating wall panel 5, that is, a portion having the protruding end surface 5a ′ on the rear surface side. As a result, the one heat insulating wall panel 5 is partially thickened at the portion corresponding to the joint 9 on the front surface side than the portion corresponding to the joint 9'on the rear surface side, so that the joints 9 and 9'are recessed. Despite the shape, joint width a on the back side
Is smaller than the joint width A on the surface side, high fire resistance performance and heat insulation performance are maintained. To put this extremely, the protrusion width H of the end surface 5a 'on the back surface side from the end surface 5a on the front surface side of one heat insulation wall panel 5 is increased to increase the other end surface 5b' on the back surface side of the other heat insulation wall panel 5. As the joint width a on the back surface side is reduced to be closer to, the fire resistance performance and heat insulation performance at the joint portion 9 on the front surface side become higher. However, it is not within the scope of the present invention that the protrusion amount H is increased to such an extent that the back surface side end surface 5a 'of one heat insulating wall panel 5 comes into contact with the back surface side other end surface 5b' of the other heat insulating wall panel 5. Therefore, the present invention has a concave shape with a width on both the front side and the back side.
The target is the one with 9,9 'formed. Therefore, the heat insulation wall panel 5 used in the connection structure of the present invention is
It is also possible to make the joint width on the front surface side narrower than the joint width on the back surface side by reversing the use. By using such a method, it becomes possible to easily change the design and appearance by changing the size of joints, even though the same heat insulating wall panel 5 is used.

Further, according to the connection structure of FIGS. 1A and 1B, the convex portion
55 has its end surface 55a and inner and outer surfaces 55b, 55b in contact with the plate packing 7, and the recess 58 has its bottom surface 58a and both surfaces 58b, 58b in contact with the plate packing 7. And recess 58
The contact area between the plate packing 7 and the plate packing 7 becomes very large. In addition, the plate-like packing 7 includes the end surface 55a of the convex portion 55 and the bottom surface 5 of the concave portion 58.
Not only is it pressed by 8a, but it is also pressed by the inner and outer surfaces 55b, 55b of the convex portion 55 and both side surfaces 58b, 58b of the concave portion 58. Therefore, the fire-shielding property and the watertight sealing property of the plate-shaped packing 7 at the fitting portion are highly reliable.

In addition, even when the wall panel 5 is moved in the direction of expanding the joint 9 when the joint is adjusted, the inner and outer surfaces 55b and 55b of the convex portion 55 and the both side surfaces 58b and 58b of the concave portion 58 with respect to the plate packing 7. Since the sliding force only slides on the plate packing 7 without changing the pressure contact force, the clamping pressure of the plate packing 7 by them does not change. Due to the synergistic effect of this fact and the fact that the above-mentioned wide contact area helps improve the watertight sealing property, the heat shielding property and the watertight sealing property at the fitting portion between the convex portion 55 and the concave portion 58 are insulated by joint adjustment or the like. Even if the wall panel 5 is moved, it is not easily damaged. When the wall panel 5 is moved in the direction of narrowing the joint 9, the end surface 55a of the protrusion 55 and the recess 58
Since the clamping pressure of the plate-like packing 7 due to the bottom surface 58a of the plate becomes large, and the clamping pressure at other places does not change,
In this case, the fire shielding property and the watertight sealing property are not impaired at all.

On the other hand, if rainwater or the like enters the inside for some reason, the rainwater or the like will not enter the surface 71 of the plate packing 7 and the recess.
It is discharged through the space passage 8 between the bottom surface of 56. That is, when the heat insulating wall panel 5 is used for vertical sizing, rainwater or the like falls through the space passage 8, and when the heat insulating wall panel 5 is used for horizontal sizing, the space passage 8 is used. Rainwater and the like will flow down according to the height difference of the space passage 8 only by giving a slight gradient that is not apparent to 8.

When connecting the heat insulation wall panel 5 with the above-mentioned connection structure,
If the plate-like packing 7 is held in advance on one end side or the other end side of the heat insulation wall panel 5, the plate-like packing 7 will be naturally arranged at the above-mentioned predetermined position only by connecting the heat insulation wall panels. As it is installed, it is convenient and construction efficiency is improved.

FIG. 2A shows a plate packing 7 on the other end side of the heat insulation wall panel 5.
It shows the case of holding and connecting. That is, in this case, the plate-like packing 7 is used as a closing member that closes the gap between the opposite ends of the front surface material 51 and the back surface material 52 of the heat insulating wall panel 5. When the plate-like packing 7 is also used as the closing member in this manner, the closing member 54 such as aluminum foil (see FIG. 1A and FIG.
It is convenient to omit (see Fig. 1B). From the state shown in FIG. 2A, when the convex portions 55 ′, 55 ′ of one heat insulating wall panel 5 are inserted into the concave portions 58 ′, 58 ′ of the other heat insulating wall panel 5, the tips of the convex portions 55 ′, 55 ′ are inserted. When the plate-like packing 7 is pushed and deformed, and is completely inserted and fitted, the plate-like packing 7 has the convex portion 55 'and the concave portion 58' as described in FIGS. 1A and 1B.
And the protruding portion 59.

FIG. 2B shows a plate packing 7 on one end side of the heat insulation wall panel 5.
It shows the case of holding and connecting. That is, in this case, the plate-like packing 7 is temporarily adhered and held to the end surfaces 55a, 55a of the pair of convex portions 55 ', 55'. When the convex portions 55 ′, 55 ′ of the one heat insulating wall panel 5 are inserted into the concave portions 58 ′, 58 ′ of the other heat insulating wall panel 5 from the 2B state, the protrusion 5
The plate-like packing 7 is pushed and deformed by the tip of 9 and when it is completely inserted and fitted, the plate-like packing 7 has a convex portion 55 ′ and a concave portion 58 ′ as described in FIGS. 1A and 1B. It is arranged between the fitting portion and the protruding portion 59.

Although not shown in the above example, the configuration in which one end surface on the back surface side of one heat insulating wall panel projects more than one end surface on the front surface side, and the other end surface on the back surface side of the other heat insulating wall panel is It goes without saying that both of the configurations of protruding from the other end surface on the surface side may be provided.

[Advantage of Invention] As described above, according to the present invention, the width of the recessed joint on the front surface side between the adjacent heat insulating wall panels is made wider than the width of the recessed joint on the back surface side, It is possible to arbitrarily change the appearance and design of the entire wall to two types by reversing the two wide and narrow joints on the front and back sides inside and outside, but the wall at the joint on the wide side Since the thickness of the panel is partially increased by the end of one heat insulation wall panel with a protruding end surface, even when the construction is performed with either the front and back joints of different widths facing the outer surface. It is possible to suppress deterioration of heat insulation performance and fire prevention performance at joints.

In addition, the packing interposed between the fitting parts of the pair of convex parts and the pair of concave parts secures the shielding function to prevent the fire from flowing through the gap between the adjacent heat insulating wall panels, and the fire resistance performance. Not only can it improve the water quality, but it can also prevent rainwater from entering the interior, and even if some rainwater intrudes inward due to capillary action, etc. The rainwater, etc. is transferred between the packing surface and the bottom surface of the recess formed between the pair of protrusions on one heat insulation wall panel, and is transferred to the space passage that is in a depressurized state to the outside, and the wall panel is vertically attached. In the case of sizing, the wall panel is dropped downward, and in the case of sizing, when the wall panel is laterally attached, a slight slope is given during construction to allow rainwater etc. that has infiltrated to flow smoothly down the slope, and to the further inside. Stop infiltration An effect that can be exhibited the kind of excellent sealing properties.
