An inner engagement groove, an outer engagement groove, an inner vertical surface portion that stands up above the opening and penetrates the fixing bolt, an outer vertical surface portion, and a connecting portion that connects the compatible surface portions. When it is provided, the outer wall structure has an attachment panel attached and an exterior panel is laid.
The exterior panel has an exterior material on the outermost side, and at least one base layer is laminated on the inside, and a fixing bolt is passed through the compatible surface portion of the fixture attached to the structural material. The fixing bolt can be fastened and fixed by being connected to a connecting member penetrating the base layer of the exterior panel.

  Hereinafter, each of the structural material, fixture, fixing bolt, and exterior panel (exterior material, base layer, connecting member) used in the present invention will be described.

Structural material The structural material used in the present invention is a shape steel provided with a portion in which the inner extending piece from the inner flange and the outer extending piece from the outer flange respectively face the opening as described above. The lip groove-shaped steel (C-shaped steel) used for the lip-shaped steel may be used. Of these, the lip groove steel is a lightweight steel mainly used for purlins, beams, etc., and is also called C-shaped steel or sea channel, and the flanges are orthogonal to the inside and outside of the horizontal piece of web. An outward facing piece (inner extension piece) is formed at the tip of the inner flange that is formed inward, and an inward piece (outer extension piece) is formed at the tip of the outer flange that is located outward. ing. As described above, the inside and outside of these portions are for the purpose of simplifying the explanation, and do not limit the inside / outside relationship in the actual arrangement state.

-Mounting tool The mounting tool used in the present invention has an inner engagement groove that engages with each of the inner extension piece and the outer extension piece of the structural material from the opening of the structural material in the assembled state as described above. A first engagement groove, an inner vertical surface portion that is disposed above the opening and penetrates the fixing bolt, an outer vertical surface portion, and a connecting portion that connects the compatible surface portions.

  The connecting portion of this fixture connects the compatible surface portions as described above, and is not particularly limited in shape and configuration, for example, may be plate-like, but is assembled as in the illustrated embodiment described later. In FIG. 5, side portions extending from the left and right side edges of the connecting portion of the fixture to the structural material side (inward side) may be formed. That is, it may be formed in a U-shaped cross section.

Further, the inner engagement groove and the outer engagement groove of the fixture may be any ones that can be stably fitted by engaging with the inner extension piece and the outer extension piece of the structural material. These engaging grooves prevent the structural material from falling into the opening by the upper part of the engaging groove and prevent the structural member from coming out of the opening by the lower part. Get on the inner extension piece in front).
In order to attach this fixture to the structural material having the above-described structure, as shown in an illustrated embodiment (FIG. 3) to be described later, first, only one of the ends is positioned within the opening of the structural material. Inclined, engage the engagement groove formed at one end, and then engage the engagement groove gradually deeper, while pushing the other end into the opening. Also good.
In this aspect, it is desirable that one of the engagement grooves is formed deeper than the other. For example, when the inner engagement groove is formed deeper than the outer engagement groove, first, the inner engagement groove is formed. It can be easily constructed by facing the inner extension piece of the structural member in an inclined manner and pushing the outer end portion into the opening. In this case, it is desirable that the outer engagement groove be pressed against the outer extending piece by tightening the fixing bolt.

In addition, the attachment aspect of an engagement groove | channel is not limited to the above-mentioned aspect, You may make it attach as follows.
That is, the mounting tool is inclined with respect to the structural material, the inner and outer ends are positioned in an immersive manner in the opening of the structural material, and then, for example, the left or right side of the outer engagement groove is positioned on the structural material. Apply to the outer extension piece and use it as a fulcrum for rotation. Then, the fixture is rotated (turned) while maintaining a substantially horizontal shape, the left and right inner locking grooves of the fixture are engaged with the inner extension piece of the structural material, and the left and right outer extension pieces are engaged with the outer extension piece. You may make it attach by engaging a direction locking groove.

In addition, the inner engagement groove and the outer engagement groove may be the same as the inside or outside, or may be different in the inside and outside, and the formation mode is not particularly limited. For example, these engagement grooves may be formed on the vertical surface portion and the side surface portion, or may be formed in combination.
The case where this fixture is made of a material such as a metal plate will be described.For example, the end portion of the side surface portion on the structural material side is projected to form the outer portion of the engaging groove, and the lower end portion of the elevation portion is The aspect in which the bent piece forms an inward part may be sufficient.
Further, the outer engagement groove may be formed by cutting the end edge of the side surface portion of the fixture in the assembled state to form the engagement groove. In this aspect, the engagement groove is formed orthogonal to the side surface portion, and the strength is high.
Furthermore, the both engagement grooves may be formed such that an engagement groove is formed between two bent pieces obtained by bending the lower end of the vertical surface portion of the fixture while changing the height. This embodiment can be easily processed and requires less material.

  Further, as described above, the inner vertical surface portion and the outer vertical surface portion of the fixture are arranged above the opening portion to allow the fixing bolt to pass therethrough (having through holes). The configuration is not limited, and the configuration is not limited to a rectangular shape as in the illustrated embodiment described below. Further, the shape of the through hole is not particularly limited, and may be formed in any manner depending on the fixing bolt to be used.

Fixing bolt The fixing bolt used in the present invention is a rod-like member that is fixed by being connected to a connecting member that penetrates the compatible surface portion of the fixture and penetrates the base layer of the exterior panel. As this fixing bolt, a general bolt in which a head is formed at one end and a male screw part is formed on the other side may be used, and the male screw part on the other side may be fastened to the connecting member, Alternatively, stud bolts having both ends formed by male screw portions may be used, and a nut may be tightened at one of the end portions.

-Exterior panel As for the exterior panel used for this invention, an exterior material is laminated | stacked on the innermost side and at least one base layer is laminated | stacked inside, and the through-hole which a connection member penetrates is formed in this base layer.

-Exterior material The exterior material, that is, the exterior material arranged on the outermost side, is made of a metal plate material or the like, and has a fixing part that can hold the head of the connecting member that penetrates the base layer or that can be connected to the tip. I just need it. As shown in the illustrated embodiment described later, the fixing portion is formed in a substantially U shape that forms a space that opens to the side, and holds a member that can be connected to the tip of a connecting member such as a nut, for example. Good.
As this exterior material, among the left and right side edges of the face plate part, a fixing part and a connecting part are provided on one side edge, a connection receiving part is provided on the other side edge, and the connecting part and the connection receiving part are fixing parts. Can be connected in the internal space, and the connection portion and the connection receiving portion of the adjacent exterior material can be connected and the surface of the fixing portion can be blocked, and a configuration using a kind of exterior material may be used. As in the example, two or more of an exterior material having a fixing portion and an exterior material not having a fixing portion may be used in combination.
Further, the face plate portion may be substantially flat, or may be wavy with irregularities formed on the front surface side or the back surface side.

The fixing portion of the exterior material is preferably provided on the back side of the exterior material, and the size of the exterior material is particularly limited as long as it can accommodate the head of the connection member or the nut connecting the tip of the connection member. The shape is not limited, and the shape is not limited to a substantially U-shape that opens sideways as in the illustrated embodiment described later.
When the fixing part is provided on the back side of the exterior material, that is, the base layer side, it is impossible to insert a tool or the like required for tightening the tip (head) of the connecting member or the attached nut into the fixing part. It is desirable to have a shape configuration to prevent co-rotation of the tip (head) of the member or the attached nut.

-Base layer The base layer laminated | stacked inside the said exterior material (back side) consists of at least one layer which has heat insulation performance, fire prevention performance, etc., and is provided with the through-hole which a connection member penetrates. As a base material constituting such a base layer, various synthetic resin foams that require a predetermined thickness may be used, gypsum board, PC panel or ALC panel, other fireproof materials or fireproof materials, etc. Inorganic materials may be used, a structure integrated in advance with one surface (one surface) of the exterior material, or a separate material may be prepared. Further, as shown in the illustrated embodiment to be described later, a board having a plurality of performances, a board having different performances or the like combined (laminated), or a laminated board having a plurality of performances may be used.
Further, the through hole provided in the base layer reaches (communicates with) the fixing portion of the exterior material.
In addition, this foundation layer should just be integrated with the said exterior material main body in the laying state, for example, may be previously adhere | attached with the exterior material using the adhesive agent etc. at the time of construction, engagement etc. It may be fixed so as not to be physically separated from each other, and is not particularly limited thereto, and may be a separate body before the arrangement and simply overlapped at the time of construction to form a laminated state.

  When the base layer in the present invention is defined as having a through-hole through which the connecting member passes as described above, the heat insulating material (base material 7A) in the illustrated embodiment described later is disposed between adjacent fixing portions. Therefore, although it is formed along the back surface of the exterior material, since it does not have a through hole, it cannot be said to be the base layer strictly. However, since they are arranged at intervals corresponding to the through holes, this case is also regarded as the underlayer.

-Connecting member The connecting member used in the present invention penetrates the foundation layer of the exterior panel, and is provided with a head held by the fixing unit at one end leading to the fixing unit of the exterior material, Either a male screw part that is screwed into a nut held in the fixing part or a female screw part that is screwed into a small bolt held in the fixing part is formed, and the base layer side A female screw portion into which the fixing bolt is screwed is formed at the other end located at the position. As such a connecting member, a special high nut already on the market is used in the illustrated embodiment described later.
The special high nut is capable of screwing the male screw portion into a female screw portion formed in the fixing portion, and is capable of screwing the female screw portion to the tip of the fixing bolt, Since the base layer side is thicker than the material side, the large-diameter portion is prevented from coming off when the male screw portion is screwed to the female screw portion formed in the fixing portion, so that the exterior panel is stable. Integration can be achieved.
The connecting member is not limited to one member such as the special high nut. For example, a plurality of members in which a high nut is attached (fixed) to one end of a stud bolt whose both ends are formed by male screw portions. It is also possible to use a combination of these. In addition, the length of the connecting member may be changed according to the thickness of the base layer, and may be changed as appropriate according to the thickness of the base material to be used.

And the attachment structure of the exterior panel of this invention is the said connection member which penetrates the said fixing bolt and the base layer of the said exterior panel while making the said fixing bolt penetrate the compatible surface part of the said fixture attached to the said structural material. Connected to and tightened.
Therefore, in the present invention, neither the welding operation to the structural material nor the drilling operation for inserting the bolt is required, and the fixture and the exterior material can be easily and reliably attached to the structural material.
In addition, the mounting tool used in the present invention minimizes the use of tools and does not require hammering in the mounting work to the structural material. The construction method made can be implemented.

  In addition, as described above, the connecting member that penetrates the base layer of the exterior panel and the fixing bolt that penetrates the fixture attached to the structural material integrally connect the respective end portions. The connecting member that has been attached to the fixing member and the fixing bolt that has been attached to the structural member or the fixture may be connected at that time, or the connecting member and the fixing bolt that are integrated in advance may be connected to the exterior panel. You may use for attachment and attachment to a structural material or a fixture.

Furthermore, the mounting method of the exterior panel of the present invention includes a first step of attaching the fixture to the structural material, a second step of penetrating the connecting member through the base layer of the exterior panel, and a fixing bolt on the fixture. And a third step of allowing the fixing bolt to be connected to the connecting member of the exterior panel and fastened and fixed.
These first, second, and third steps can be performed very easily as described above, and all the operations are performed from the exterior inner surface side. There is no need to set up a scaffold, and the space and cost for that purpose can be reduced.

1A and 1B, the mounting structure of the exterior panel 5 of the present invention is such that the inner extending piece 221 faces the opening portion 20 from the inner flange 22 and the outer extending piece 231 faces the opening portion 20, respectively. The structural member 2 made of steel is provided with an inner engagement groove 15 and an outer engagement groove 16 that are engaged with the extended pieces 221 and 231, and the fixing bolt 4 that is erected above the opening 20. This is an outer wall structure in which the exterior panel 5 is laid by attaching the fixture 1 including the inner vertical surface portion 12 to be penetrated, the outer vertical surface portion 13, and the connecting portion 11 that connects the compatible surface portions 12 and 13.
The exterior panel 5 is formed by laminating an exterior material 6 on the outermost side and an inner layer 7 of at least one layer on the inner side, and fixing bolts to the compatible surface portions 12 and 13 of the fixture 1 attached to the structural material 2. 4, and the fixing bolt 4 is connected to a connecting member 8 that penetrates the base layer 7 of the exterior panel 5 and is fastened and fixed.

  As described above, for the purpose of simplifying the description of the structural material, the internal and external directions of the part notation are set. In FIGS. 3A and 3B, the opening 20 of the structural material 2 is disposed upward. Therefore, the near side of the drawing is the outdoor side and corresponds to the outside (outside), and the far side is the indoor side and corresponds to the inside (inward). Further, in FIG. 3C, the upper side of the drawing corresponds to the inner side (inward), and the lower side corresponds to the outer side (outward). 3D to 3G, the right side of the drawing corresponds to the inside (inward), and the left side corresponds to the outside (outward).

Each member, the exterior material 6, the base layer 7, and the connecting member 8 constituting the exterior panel 5 in the first embodiment will be described below with reference to FIG.
In the first embodiment, the exterior material 6 includes two types of an exterior material 6A having a fixing portion 62 that fixes (holds) the tip of the connecting member 8 that penetrates the base layer 7 and an exterior material 6B that does not have. Used.
Further, the base layer 7 includes a heat insulating material 7A made of a synthetic resin foam located on the outer side in contact with the exterior material 6 and an ALC panel 7B located on the inner side.

Of the two types of exterior materials 6 (6A, 6B), the exterior material 6A having the fixing portion 62 includes a space portion 62 on the back surface side of the face plate portion 61 serving as a finished surface as shown in FIG. This is an aluminum extrusion mold material in which a protrusion 611 protruding toward the surface side in a substantially T shape is provided at the approximate center of the face plate portion 61, and connecting portions 63a and 63b are provided at opposing edges. Then, a fixing portion 62 that is a U-shaped space opened on the side (left side in the drawing) is formed adjacent to the connection portion 63a on one side (right side in the drawing), and the nut 6c is held.
As shown in the figure, the exterior material 6B is substantially the same as the exterior material 6A in terms of the configuration of the face plate portion 61. This is an aluminum extrusion mold material provided with 63d.
Although the connection portions 63a to 63d are not described in detail, the connection portion 63b of the exterior material 6B and the connection portion 63c of the exterior material 6B adjacent to each other are engaged and connected, and the exterior is adjacent to the connection portion 63d of the exterior material 6B. The connecting portion 63a of the material 6A is engaged and connected.

Of the two kinds of base layers 7 (7A, 7B), the heat insulating material 7A located outside is made of a synthetic resin foam, and the heat insulating material 7A used in the first embodiment is shown in FIG. As shown, the edge shape is cut into a rectangular shape.
The heat insulating material 7A has a width corresponding to the space between the adjacent fixing portions 62 and 62, and is fitted between the connecting portion 63a of the exterior material 6A and the connecting portion 63d of the exterior material 6B. Can be handled integrally with the exterior materials 6A and 6B, and also serves to prevent the nut 6c from falling off the fixing portion 62.
Thus, since the heat insulating material 7A is disposed between the fixing portions 62, 62, the heat insulating material 7A does not exist on the inner surface side of the fixing portion 62, and a connecting member as shown in FIG. 8 can be regarded as being arranged so as to avoid 8 and formation of a through hole or the like is not required.

  Of the underlayer 7, the ALC panel 7B located inside has a width corresponding to two of the heat insulating layers 7A as shown in FIG. 2 (c), and is used for this first embodiment. The two ALC panels 7B correspond to the total width of four sheets of the exterior materials 6A and 6B. In the ALC panel 7B, through holes 71 and 71 ′ for inserting the connecting member 8 are formed at substantially the center and edge, and a plurality of cavities 70 are formed in the ALC panel 7B itself. What is necessary is just to form through-holes 71 and 71 'of a different diameter size in the inner part and outer part which pinch | interpose. If the diameter of the small diameter portion 81 of the connecting member 8 to be described later is D1 and the diameter of the large diameter portion 82 is D2, the through hole 71 is inserted through the male screw portion 81 at the outer portion adjacent to the fixing portion 62. Therefore, it may be formed slightly larger than D1, and the inner portion of the cavity 70 may be formed slightly larger than D2 in order to insert the large diameter portion 82. On the other hand, the through hole 71 ′ formed at the edge is similarly formed with the outer portion formed at D1 and the inner portion formed at D2, but the edge of the central ALC panel 7B shown in the figure is partially adjusted and adjacent ALC is formed. It is formed by adjusting the arrangement interval of the panel 7B.

As described above, the connecting member 8 penetrating the base layer 7 is a member having the small-diameter portion 81 having the diameter D1 and the large-diameter portion 82 having the diameter D2, as shown in FIG. As shown in FIGS. 5E and 5F, a male screw portion 83 is formed on the outer periphery of the tip of the small-diameter portion 81, and a cylindrical space is provided in the large-diameter portion 82 from the inner end so that the female screw portion 84 is formed. This is a special high nut that is formed and further provided with a flange portion 85 that widens outward at the innermost end of the large-diameter portion 82.
Therefore, the male screw portion 83 of the connecting member 8 can be screwed to the nut 6 c held by the fixing portion 62, and the female screw portion 84 can be screwed to the fixing bolt 4. Further, the flange portion 85 plays a role of preventing the ALC panel 7B from being detached to the inside, so that the male screw portion 83 of the connecting member 8 is attached to the nut 6c held by the fixing portion 62. Thus, the exterior material 6A and the ALC panel 7B are integrally connected, and the exterior panel 5 including the heat insulating material 7A is integrated in a state of being sandwiched therebetween.

Next, the structure of the said fixture 1 and the structural material 2 is demonstrated based on FIG.
As described above, the fixture 1 is erected above the inner engagement groove 15 and the outer engagement groove 16 that engage with the extended pieces 221 and 231 of the structural material 2 and the opening 20 of the structural material 2. This is a member that includes an inner vertical surface portion 12 that passes through the fixing bolt 4, an outer vertical surface portion 13, and a connecting portion 11 that connects the compatible surface portions 12 and 13.
The fixture 1 of the illustrated embodiment is made of a material such as a metal plate, and has side portions 14 and 14 extending from the left and right side edges of the substantially rectangular connecting portion 11 to the structural material 2 side. Inward and outward directions, a substantially square inner upright surface portion 12 and an outer upright surface portion 13 are formed, respectively. The connecting portion 11 and the side surface portions 14 and 14 are substantially U-shaped frames, and have through-holes 121 and 131 through which the fixing bolt 4 passes at the approximate center of the compatible surface portions 12 and 13.
The inner engagement groove 15 is formed by projecting (projecting piece 141) an end portion of the side surface portion 14 on the side of the structural material 2 to form an outer portion of the engagement groove 15, and bending the lower end of the elevation surface portion 12. The bent piece 122 forms an inward portion. That is, the inner engagement groove 15 of the first embodiment is formed between the bent piece 122 and the protruding piece 141.
The outer engagement groove 16 is a form in which an engagement groove 16 is formed by forming a cut (from the front side in the drawing) at the edge of the side surface portion 14.

  As described above, the structural material 2 is shaped steel in which the inner extending piece 221 from the inner flange 22 and the outer extending piece 231 from the outer flange 23 face the opening 20, respectively. Channel steel was used. In the structural material 2 of the illustrated embodiment, the opening 20 is disposed upward, the web 21 is disposed on the lower surface, the inner flange 22 is disposed on the back side, and the outer flange 23 is disposed on the front side.

  The fixing bolt 4 is used to pass through and fix the compatible surface portions 12 and 13 of the fixture 1. In the illustrated embodiment, a hexagonal bolt is used, and the head 41 is arranged on the innermost side. The male screw portion 42 extending to the outside can be attached to the female screw portion 84 of the connecting member 7 and fastened and fixed.

Below, the 1st process in the attachment method of the exterior panel of this invention, ie, the process of attaching the said fixture 1 to the said structural material 2, is demonstrated based on FIG.3 (e)-(g).
First, as shown in FIG. 3 (e), the inner flange 22 of the structural member 2 is brought closer to the inner vertical surface 12 side of the fixture 1, and this inner engagement groove 15 is extended to the inner side of the structural member 2. It arrange | positions so that it may apply to the front-end | tip of the piece 221. FIG.
Next, as shown in FIG. 3 (f), the inner engagement groove 15 of the fixture 1 is pushed in from the inside so as to be deeply engaged with the inner extending piece 221 of the structural member 2.
Then, as shown in FIG. 3G, when the inner engagement groove 15 of the fixture 1 and the inner extending piece 221 of the structural member 2 are sufficiently deeply engaged, the outer vertical surface portion 13 becomes the structural member 1. Since it approaches the outer flange 23, it can be pressed from the inside so as to push it in, and the state of FIG. 3D can be obtained. 3D shows the fixture 1 in a state in which the head 41 of the fixing bolt 4 is fastened and fixed.
In addition, since this fixture 1 minimizes the use of tools and does not need to be struck in the attachment work to the structural material 2, the generation of “sound” is extremely small, and consideration is given to the neighborhood. Construction method can be implemented.

Next, a second step of allowing the connecting member 8 to penetrate the base layer 7 of the exterior panel 5 having the above-described configuration will be described.
As shown in FIGS. 2A and 2B, the exterior materials 6A and 6B are alternately connected so that the two exterior materials (6A and 6B) are along the heat insulation material 7A. When the exterior material 6A is disposed as indicated by a dotted line, the connection part 63b is attached to the lower left and the connection part 63a is inclined to the upper right so that the connection part 63b is already attached obliquely from above as indicated by an arrow. It is connected (connected) to the exterior material 6B. Further, when the exterior material 6B is arranged, the exterior already attached from obliquely below as indicated by an arrow in a state of being held in a substantially horizontal state so that the connection portion 63d is on the left side and the connection portion 63c is on the right side. What is necessary is just to connect (connect) to the material 6A.
Since the heat insulating material 7A has a width dimension corresponding to between the adjacent fixing portions 62 and 62 as described above, the heat insulating material 7A is fitted between the connection portion 63a of the exterior material 6A and the connection portion 63d of the exterior material 6B. Although it can be mounted in a uniform manner, an adhesive or the like may be used in combination.

Subsequently, the ALC panel 7B is placed along the inside of the heat insulating material 7A. Since the ALC panel 7B has a width corresponding to two of the heat insulating materials 7A as shown in FIG. In the exterior materials 6A and 6B, two pieces each correspond to a total width of four sheets. In the ALC panel 7B, a through hole 71 through which the connecting member 8 passes is formed in advance at a predetermined position with a predetermined dimension (a diameter D1 at the outer portion of the cavity 70 and a diameter D2 at the inner portion). desirable.
Then, the connecting member 8 is penetrated in a state where the ALC panel 7B is placed inside the heat insulating material 7A and fixed to the nut 6c held by the fixing unit 62. As described above, since the exterior panel 5 is integrated by the attachment of the connecting member 8, the heat insulating material 7A and the ALC panel 7B are not particularly required to be joined or bonded.

And as a 3rd process, while making the said fixing bolt 4 penetrate the said fixture 1, this fixing bolt 4 is connected to the connection member 8 of the said exterior panel 5, and it clamps and fixes, but it has already said said 1st process. The fixture 1 is attached to the structural member 2 and it is very easy to pass the fixing bolt 4 through the compatible surface portions 12 and 13 of the fixture 1. In addition, it is very easy to connect and fasten the tip of the tip to the connecting member 8 already attached to the exterior panel 5 in the second step.
As described above, the operation itself is extremely easy, but in fact, it is difficult to move the constructed exterior panel 5 and the structural material 2 such as a structural steel used for a beam or a main building of a building. But it is difficult to move itself. Therefore, after attaching the fixture 1 to the structural material 2 in the first step, the third step can be performed very easily by forming the exterior panel 3 or performing the second step in the vicinity thereof. Can do.

  As described above, the mounting structure of the exterior panel 5 according to the present invention is an outer wall in which the exterior panel 5 in which the base layer 7A, 7B is laminated inside the structural material (purlin) 2 such as C-shaped steel with the fixture 1 interposed therebetween. By connecting a fixing bolt 4 that penetrates the fixture 1 to a connecting member 8 that penetrates the base layer 7B inside the exterior panel 5, the exterior panel 5, the fixture 1, and the structural material 2 are connected. Are fixed together. Therefore, neither a welding operation to the structural material 2 nor a drilling operation for inserting a bolt is required, and the exterior panel 5 can be easily and reliably attached to the structural material 2. Furthermore, it can be easily handled by simply changing the length of the connecting member 8 used according to the thickness of the base layer 7 of the exterior panel 5.

  Furthermore, since the installation method of the exterior panel 5 of the present invention can be performed entirely by work from the inner surface of the exterior, and it is not necessary to waterproof the exterior surface, there is no need for a scaffold or the like during construction. . Therefore, it is possible to keep the space for forming the scaffolding, the construction period and cost for installation / disassembly low.
