Description

The present invention relates to a set metal fitting and a panel with a metal fitting, and particularly relates to a set metal fitting and a panel with a metal fitting, which are suitable for construction of a wooden panel on an outer wall surface of a building or the like.

In order to effectively utilize the planted forests that were planted after the war as resources and prevent the deterioration of the multi-functionality of forests such as national land conservation, in Japan, the Law Concerning the Promotion of the Use of Wood in Public Buildings, etc. It was enforced in.

With the enforcement of this law, there is an increasing demand for exterior walls using cladding boards, siding boards, louvers, etc. (hereinafter collectively referred to as "wooden panels") made of wood materials.

In the construction of such a wooden panel, it is necessary to firmly fix it so that rattling does not occur even if an external force such as wind is applied. On the other hand, the durability period of the wood panel is relatively short compared to that of stone and ceramics, so it is necessary to frequently perform maintenance work and replacement work of the wood panel.

As a configuration capable of responding to such a request, for example, Patent Document 1 is known.

In FIG. 9A of the same document, a support for supporting a plurality of louver members constituting a wooden louver (wooden panel) is provided, and the support is fixed to the back surface of the support and the skeleton (wall surface) of the building. A configuration is disclosed in which metal fittings are fixed to the surface of a wall surface panel in advance, bolts are inserted through both metal fittings, and the metal fittings are tightened with nuts.

Further, FIG. 9B of the same document discloses a structure in which each louver member is bolted to the wall surface panel.

JP-A-2015-48623

In the configuration as described in Patent Document 1, the wooden panel can be attached to the wall surface and can be removed.

However, according to the configuration of Patent Document 1, it is not always easy to perform the attachment work of attaching the wood panel and the removal work of removing the attached wood panel.

In particular, in the configuration of Patent Document 1, it is necessary to align the metal fitting fixed to the back surface of the wooden louver as a wooden panel and the metal fitting fixed to the surface of the wall surface panel and insert the bolt. Since the wooden panel is relatively heavy (for example, about 30 kg), the work of supporting such a heavy object on a scaffold, for example, aligning the metal fittings with each other and inserting the bolt is extremely inefficient. The installation work was difficult.

Further, since it is necessary to perform the attachment work with bolts and the removal work of screwing off the bolts at a high place, for example, there is a problem that the bolts are easily dropped during the work.

The present invention has been made in view of the above-mentioned problems, and it is possible to easily attach and remove the wooden panel to the wall surface, and when the wooden panel is attached to the wall surface and to be exteriorized, it is rigid. An object of the present invention is to provide a set metal fitting and a panel with a metal fitting that can obtain a stable mounting structure without rattling.

In order to solve the above problems, the present invention is a set metal fitting for detachably fixing a wooden panel to a wall surface of a building, and a panel-side fixing plate and a panel-side fixing plate fixed to the back surface of the wooden panel. A hook metal fitting including a plate-shaped hook that protrudes in a cantilever shape and hangs down, and a wall surface side fixing plate fixed to the wall surface and the wall surface side fixing plate provided on the wall surface side fixing plate to insert and remove the hook up and down in a loosely fitted state. A receiving metal fitting including a hook receiving metal fitting having a possible opening is provided, and the hook receiving metal fitting of the receiving metal fitting is provided integrally with a receiving plate facing the wall surface side fixing plate and both side portions of the receiving plate. It has a pair of side plates extending toward the wall surface side fixing plate side and having at least an upper end portion fixed to the wall surface side fixing plate, and one of the hook and the hook receiver has a plate thickness direction of the hook. A set characterized in that a projecting portion is provided that elastically presses the hook inside the hook receiver at the end of the stroke when the hook is inserted into the hook receiver. It is a metal fitting.

In this aspect, when the wooden panel is detachably fixed to the wall surface, the wooden panel is attached by moving the wooden panel up and down by using the receiving metal fitting fixed to the wall surface and the hook metal fitting fixed to the wooden panel. Work and removal work can be performed, and workability is significantly improved even when the work is performed at a high place, for example.

In particular, since the hook of this embodiment hangs down in a cantilever shape, it is introduced into the hook receiver on the wall surface by the action of lowering the wooden panel. Therefore, since the mounting work can be performed by using the weight of the wooden panel, the efficiency is significantly improved and the mounting work becomes easier as compared with the bolt insertion work.

Further, even in the replacement work of the wood panel attached to the wall surface, the set metal fittings can be carried out in a predetermined position on the wall surface or in a state of being fixed to the back surface of the wood panel. Therefore, the work of attaching and detaching bolts and the like becomes unnecessary, and there is no risk that the member separated from the wooden panel will fall during the work.

In addition, in this embodiment, since the hook is inserted and removed in the opening of the hook receiver in a loosely fitted state, the operator can easily insert the hook and smoothly insert the hook into the hook receiver. Further, in this embodiment, a pair of side plates are integrally formed on both side portions of the receiving plate (including a mode in which the pair of side plates are integrally formed and connected by welding or the like), and at least the upper end portions of the pair of side plates are concerned. Being fixed to the wall side fixing plate, the opening of the hook receiver provides a solid mechanical structure. Therefore, even if a twist occurs when inserting the hook while searching the hook receiver, sufficient durability can be exhibited, and the hook receiver does not follow the hook insertion / removal operation, so that the removal operation is performed. Will be even easier.

On the other hand, when the hook is inserted to the end of the stroke, the protruding portion elastically presses the hook inside the hook receiver. Therefore, although the shape and dimensions are set so that the hooks are inserted and removed from the hook receiver at intervals, the rattling in the thickness direction of the wooden panel is regulated together with the rattling in the vertical direction. ..

In the set metal fitting of the preferred embodiment, the hook is inserted into the opening at intervals in the plate thickness direction, and the interval is set in the range of 2 to 5 times the plate thickness of the receiving plate. The protruding amount of the protruding portion is set in the range of 125% to 150% of the difference between the interval and the plate thickness of the receiving plate. In this aspect, there is no hindrance to the hook insertion / removal work, and the hook can be reliably pressed to regulate rattling in the panel thickness direction.

In a set metal fitting of a preferred embodiment, an engaging convex portion formed on either one of the hook and the receiving plate and an engaging convex portion formed on either one of the hook and the receiving plate are formed to engage with the engaging convex portion. It is provided with an engaging recess that defines the end of the stroke. In this aspect, by engaging the engaging convex portion and the engaging concave portion, simple extraction regulation can be achieved, and further, the heights of the fixed wooden panels can be made uniform. Therefore, the operator can easily fix the wooden panel to the wall surface simply by inserting the hook into the hook receiver of the metal fitting from top to bottom. Moreover, even when constructing a specification in which one exterior design is composed of a plurality of wooden panels, the heights of adjacent wooden panels can be precisely aligned. On the other hand, when removing the wood panel, it is only necessary to grasp the wood panel and lift it upward. As a result, the engaging convex portion and the engaging concave portion are disengaged, and the hook comes out above the hook receiver.

In the set metal fitting of the preferred embodiment, the engaging concave portion is formed on the receiving plate so as to lock the engaging convex portion on the upper end side of the protruding portion, and the engaging convex portion is formed on the hook. It is formed in a pair of hemispheres arranged side by side in the width direction of. In this aspect, since the engaging convex portions formed in a hemisphere and forming a pair are locked to the engaging concave portions, the contact area between each engaging convex portion and the engaging concave portion can be reduced. Therefore, when the engaging convex portion and the engaging concave portion are engaged, they are not excessively locked, and the hook removal work does not become an extra burden. Moreover, since the receiving plate can hold the hook at three points by the protruding portion and the two engaging convex portions that are locked to the engaging concave portion on the upper end side of the protruding portion, a stable support structure can be obtained. Obtainable.

In the set metal fitting of the preferred embodiment, the engaging recess extends vertically, and the starting end side of the stroke is set to a size that allows the engaging convex portion to be loosely fitted, and the engaging concave portion advances to the ending portion side of the stroke. It is provided with a tapered guide surface that guides the engaging convex portion so that the hook is positioned to the left and right at the end of the stroke by becoming narrower accordingly. In this aspect, until the engaging convex portion reaches the end of the stroke of the hook, the engaging convex portion is loosely fitted with the engaging concave portion and can be moved with a small resistance, so that the insertion / removal work is facilitated. .. Therefore, the opening width of the hook receiver and the opening width on the upstream side of the engaging recess can be set large, and an insertion / removal structure having less resistance and higher workability can be obtained. Moreover, even if the opening width of the hook receiver is set larger than the width of the hook or the opening width on the upstream side of the engaging recess is set large, the engaging convex portion is positioned to the left and right at the end of the stroke. , The height between the wooden panels can be made uniform.

In the set metal fitting of the preferred embodiment, the engaging recess is a hole penetrating the receiving plate. In this aspect, the engaging recess can be easily formed by drilling the corresponding portion of the receiving plate during press working.

In the set metal fitting of the preferred embodiment, when the hook is mounted in the hook receiver up to the end of the stroke, the wall surface side fixing plate and the hook come into surface contact with each other, and the receiving plate and the panel side fixing plate come into contact with each other. It is configured to make surface contact. In this aspect, the hook metal fitting and the receiving metal fitting are connected in a surface contact state in combination with the fact that the protrusion regulates the rattling of the panel in the plate thickness direction. Therefore, for example, by fixing one wooden panel with a plurality of set metal fittings, the effect of positioning the wooden panel on the same plane along the wall surface by these multiple hook metal fittings can be achieved, and the panels can be unevenly landed. It can be suppressed.

Another aspect of the present invention includes a wooden panel detachably fixed to the wall surface of a building and a hook metal fitting fixed to the back surface of the wooden panel, when the wooden panel is fixed to the wall surface. A panel with metal fittings for attaching the hook metal fittings to the hook holders of the metal fittings provided on the wall surface, and the hook metal fittings are a panel-side fixing plate fixed to the back surface of the wooden panel and a piece to the panel-side fixing plate.

Hereinafter, the best mode for carrying out the present invention will be described with reference to the accompanying drawings.

First, referring to FIG. 1, the set metal fitting A according to the present invention includes a hook metal fitting 10 fixed to a wooden panel 30 (see FIGS. 4 to 6) and a receiving metal fitting 20 fixed to a wall surface. It is a set. These metal fittings 10 and 20 are all integrally molded stainless steel presses, and the wooden panel 30 (see FIGS. 4 to 6) can be attached to and detached from the wall surface by fixing the hook metal fitting 10 to the metal fitting 20. It is fixed to.

Hereinafter, the metal fittings 10 and 20 will be described.

With reference to FIG. 2, the hook metal fitting 10 is a stainless steel sheet metal member having a panel-side fixing plate 11 and a hook 12 integrally formed with the panel-side fixing plate 11.

The panel-side fixing plate 11 of the hook metal fitting 10 is a rectangular flat metal plate whose left and right sides are slightly long when viewed from the front. As an example, the total width W1 of the panel-side fixing plate 11 is set to about 50 mm, and the total height H1 is set to about 40 mm. Insertion holes 14 for inserting fastening members (not shown) embodied by bolts (or screw members such as coach screws and course threads) are formed at the four corners of the panel-side fixing plate 11. A hook 12 that is folded back from above to the back surface and hangs down in a cantilever shape is formed in the central portion of the upper edge of the panel-side fixing plate 11.

Next, the hook 12 of the hook metal fitting 10 faces the back surface of the panel-side fixing plate 11 in parallel with a predetermined interval G1. The dimension of the interval G1 is related to the plate thickness t2 of the receiving plate 24, which will be described later, and is set to, for example, about 2 to 5 times the plate thickness t2 (about 3 times in the example of FIG. 2). The front surface of the hook 12 is inclined on both side surfaces of the free end portion 12a so as to become thinner toward the lower end side. Further, the height H11 of the hook 12 is set to about 2/3 of the total height H1 of the panel-side fixing plate 11, and the free end portion 12a faces the back surface of the panel-side fixing plate 11. The width W11 of the hook 12 is set to be narrower than the total width W1 of the panel-side fixing plate 11.

Next, the receiving metal fitting 20 is formed on the wall surface side fixing plate 21 fixed to the wall surface and the front surface of the wall surface side fixing plate 21, and the hook 12 of the hook metal fitting 10 can be inserted and removed up and down together with the wall surface side fixing plate 21. It has a hook receiver 22 that forms a large opening 22a.

The wall surface side fixing plate 21 of the receiving metal fitting 20 is a rectangle that extends long to the left and right when viewed in a plane, and insertion holes 23 through which fastening members (not shown) such as embedding bolts are inserted are formed at the four corners thereof. There is. The overall width W2 of the wall surface side fixing plate 21 is set to a size for ensuring sufficient strength. Further, the total height H2 of the wall surface side fixing plate 21 is set to be substantially the same as or slightly higher than that of the hook metal fitting 10.

The hook receiver 22 of the receiving metal fitting 20 is formed in the central portion of the lower edge portion of the wall surface side fixing plate 21. Specifically, the hook receiver 22 is folded upward from the central portion of the lower edge portion and has a predetermined distance G2 (for example, 2 to 5 times the plate thickness t1 of the hook 12) with respect to the front surface of the wall surface side fixing plate 21. Double. In the example of FIG. 2, about 3 times.) A pair of side plates 25, which are integrally formed on both side portions of the receiving plate 24 and form a pair, and are bent toward the wall surface side fixing plate 21. It has 25 and.

The receiving plate 24 of the hook receiving 22 is a plate-shaped portion that is substantially square when viewed from the front. In the illustrated example, a pair of steps 22b, 22b are formed on both lower sides of the receiving plate 24. The height H21 of the receiving plate 24 is slightly shorter than the height H3 of the hook 12, and a space capable of accommodating the hook 12 over almost the entire length is formed between the receiving plate 24 and the wall surface side fixing plate 21. The width W21 of the receiving plate 24 is such that the hook 12 of the hook metal fitting 10 is inserted and removed from the opening 22a at intervals (in other words, the opening width W22 is wider than the width W11 of the hook 12). ), The width of the hook 12 is set to be slightly wider (for example, about 1.2 times) than the width W11 (see FIG. 3C).

By forming the hook 12 and the hook receiver 22 in the shape and dimensions as described above, the hook 12 has an interval (interval G2-plate thickness) of the receiving plate 24 in the plate thickness direction with respect to the opening 22a of the receiving metal fitting 20. It is configured so that it can be inserted and removed across (or with play) t1) (see FIG. 3C). Further, the hook 12 is inserted into and removed from the hook 22 during a stroke S (or insertion amount) in which the upper end of the hook receiver 22 is the start end portion S1 and the vicinity of the lower end portion of the hook receiver is the end portion S2 (FIG. 7). (A)-(C)).

Next, in order to define the stroke S when the hook is inserted into the hook receiver 22, a pair of engaging protrusions 16 and 16 arranged side by side are formed in the vertical center portion of the hook 12 and the hook. The receiving 22 is formed with engaging recesses 26, 26 corresponding to the engaging protrusions 16, 16.

The engaging protrusions 16 and 16 of the hook 12 are both substantially hemispherical and project toward the panel-side fixing plate 11. Further, the protrusion amount P1 of the engaging convex portions 16 and 16 in the interval G1 is such that the engaging convex portions 16 and 16 can be locked to the engaging concave portions 26 and 26 described later of the receiving metal fitting 20 (for example, the interval). The difference (interval G1-plate thickness t2) between G1 and the plate thickness t2 of the receiving plate 24 is set to 125% to 150%.

On the other hand, a pair of engaging recesses 26, 26 corresponding to the engaging protrusions 16, 16 formed on the hook 12 are formed on the front surface of the receiving plate 24. In the illustrated example, the engaging recesses 26, 26 are a pair of holes formed during press working and penetrating the receiving plate 24. The engaging recesses 26, 26 are formed in a symmetrical tapered shape that opens horizontally from the vicinity of the upper portion of the receiving plate 24 and narrows toward the lower side, and the tapered guide surfaces 26a, respectively, are formed on both side portions thereof. It forms 26a. Further, the lower ends of the engaging recesses 26 and 26 are formed in a curved shape along the curved surfaces of the lower ends of the corresponding engaging protrusions 16 and 16. The width W23 on the upper end side of each engaging recess 26 is set to be slightly larger than the diameter of the engaging protrusions 16 and 16 of the hook 12 so that the engaging protrusions 16 and 16 can be loosely fitted. On the other hand, the width W24 of the lower end of each engaging concave portion 26 is set to be substantially the same as the diameter of the engaging convex portion 16 so that the engaging convex portions 16 and 16 can be locked at predetermined positions. ..

The engaging protrusions 16 and 16 of the hook 12 and the engaging recesses 26 and 26 of the hook receiver 22 are formed as described above, so that when the hook 12 is inserted into the hook receiver 22, the engaging protrusions 26 and 26 are formed. The hook 12 is inserted into the hook receiver 22 until the lower ends of 16 and 16 are locked to the lower ends of the engaging recesses 26 and 26, and the lower ends of the engaging recesses 26 and 26 insert the hook 12 into the hook receiver 22. The end portion S2 of the stroke S is defined (see FIG. 7C). Further, by adopting the above configuration, the engaging protrusions 16 and 16 of the hook 12 move in a loosely fitted state in the engaging recesses 26 and 26 until they are locked to the lower ends of the engaging recesses 26 and 26. You can do it. Therefore, the hook 12 is moved with a relatively small force until it reaches the end portion S2 of the stroke S. The distance from the upper ends of the engaging recesses 26, 26 to the upper end of the receiving plate 24 is set as short as possible in order to facilitate the insertion operation.

Next, a substantially hemispherical protruding portion 27 is formed in the vicinity of the lower end of the receiving plate 24. The projecting portion 27 projects from the receiving plate 24 toward the wall surface side fixing plate 21. The protrusion amount P2 of the protrusion 27 is such that the hook 12 can be elastically sandwiched between the wall surface side fixing plate 21 and the protrusion 27, and the hook 12 can be pressed relatively firmly (for example, the interval G2). The difference between the hook 12 and the plate thickness t1 (gap G2-plate thickness t1) is set to 125% to 150% (about 130% in the example of FIG. 2). The protruding portion 27 is formed. The position is such that the hook 12 and the protruding portion 27 are engaged at a position immediately before the hook 12 reaches the end portion S2 of the stroke S, the hook 12 is inserted to the end portion S2 of the stroke S, and the engaging convex portion 16 At the position where 16 is locked to the engaging recesses 26 and 26, the protruding portion 27 is set at a position where the hook 12 is elastically sandwiched between the hook 12 and the wall surface side fixing plate 21. Therefore, the hook 12 is set with respect to the opening 22a. Although the shape and dimensions are set so that they can be inserted and removed at intervals, it is possible to regulate the rattling of the wooden panel 30 in the thickness direction and the rattling in the vertical direction.

Next, the pair of side plates 25, 25 of the hook receiver 22 extend vertically from the upper edge of the receiver plate 24 to the height at which the protruding portion 27 is formed. In the illustrated example, the upper end portions 25a of the side plates 25, 25 are fixed to the wall surface side fixing plate 21 by brazing, and the hook receiver 22 is firmly integrated via the side plates 25, 25. .. The brazing may be performed over the entire length of the pair of side plates 25, 25 in the vertical direction, although at least the upper end portions 25a of both side portions of the receiving plate 24 are sufficient. Moreover, spot welding may be performed.

Next, with reference to FIGS. 4 to 6, an example of fixing the wooden panel 30 detachably fixed to the outer wall surface 40 of the building to the outer wall surface of the building by using the set metal fitting A described above will be described. To do.

First, referring to FIGS. 4 and 5, the wooden panel 30 includes a frame member 31 and an exterior member 32 fixed to the surface of the frame member 31. The frame material 31 is a square lumber of reinforced wood whose corrosion resistance has been enhanced by, for example, heat treatment. The illustrated frame member 31 constitutes a frame body assembled in a quadrangular frame shape. The size of the frame formed by the frame member 31 varies, but may be, for example, a square of 1 m square or a rectangle having a width set shorter than that.

The exterior material 32 is a wood material composed of a plurality of unit members fixed by the frame material 31. The exterior material 32 can be finished to various specifications such as armored tension, unmatched tension, laminated tension, wood end tension, vertical louver, horizontal louver, etc., depending on the arrangement and the like. In the case of a vertical louver, the frame member 31 may be a pair of square timbers arranged one above the other. As illustrated in FIGS. 4 and 5, in the wooden panel 30 according to the present embodiment, a plurality of exterior materials 32 representing an arbitrary design as a whole are integrated by the frame material 31 and attached to the frame material 31. By being fixed to the outer wall surface 40 via the hook metal fitting 10, the wooden panel 30 having a desired exterior design can be detachably fixed to the outer wall surface 40.

Further, in the illustrated embodiment, the panel 50 with metal fittings is formed by fastening the hook metal fittings 10 of the set metal fittings A described above to the four corners of the back surface of the wooden panel 30 in advance at the factory with the fastening members shown in the drawing. , Shipped as a standard product.

Therefore, in the embodiment shown in FIGS. 4 and 5, the commercialized wooden panel 30 can be immediately attached to the outer wall surface 40 of the building structure in which the receiver is fixed to the outer wall surface 40 in advance. Installation work, etc. is no longer required, and construction work becomes easier.

With reference to FIG. 6, specifically, at the time of construction, as a first step, the mounting position is determined on the outer wall surface 40 of the building structure so as to match the dimensions of the wooden panel 30. Take out. Next, as a second step, the receiving metal fitting 20 is fixed at the marked position. Further, as a third step, the panel 50 with metal fittings is attached from one side to the other side of the outer wall surface 40 in order from the lower side. In this mounting process, the operator only needs to align the hook metal fittings 10 of the panel with metal fittings 50 with the corresponding receiving metal fittings 20 and introduce the respective hooks 12 to the corresponding hook receiving parts 22 while making a search. .. Here, since at least the upper end portions 25a of the pair of side plates 25, 25 constituting the side portions of the hook receiver 22 are fixed to the wall surface side fixing plate 21 by brazing, the hook receiver 22 is positioned in the process of positioning the hook 12. Even if it comes into contact with the receiving plate 24 inside, the hook receiving 22 is not deformed.

When the hook 12 is introduced, the panel 50 with metal fittings moves downward by its own weight, and with only a slight push-in adjustment, the engaging protrusions 16 are lowered to a position where they are locked to the lower ends of the engaging recesses 26. It is fixed.

The process of inserting the hook 12 of the hook metal fitting 10 into the hook receiver 22 of the receiving metal fitting 20 will be described with reference to FIG. 7 regarding the operation of the set metal fitting in this mounting work.

First, in the section S10 (see FIG. 7A) from the start end portion S1 of the stroke S to the position where the engaging convex portions 16 and 16 abut on the upper edge of the receiving plate 24, the lower end portion of the hook 12 receives the hook. The hook 12 can be loosely fitted inside the 22 and the hook 12 and the hook receiver 22 can be aligned with each other to start inserting the hook 12.

Next, in the section S11 (see FIG. 7B) from the position where the engaging protrusions 16 and 16 abut on the upper edge of the receiving plate 24 to entering the engaging recess 26 of the receiving plate 24, the engaging protrusions are raised. When the portions 16 and 16 are further inserted into the hook 12, the engaging convex portions 16 and 16 are elastically pushed between the wall surface side fixing plate 21 and the receiving plate 24, and the panel side fixing plate 11 and the hook. Since the receiving plate 24 is sandwiched between the receiving plate 24 and the engaging protrusions 16 and 16, the resistance increases slightly, but the section S11 extends from the upper ends of the engaging recesses 26 and 26 to the upper end of the receiving plate 24. Since the interval is set as short as possible, it is relatively short. Therefore, in combination with the weight of the wood panel 30, the worker lowers the wood panel 30 with a relatively small force through a relatively short section S11, and inserts the engaging convex portion 16 into the engaging recesses 26 and 26. Can be made.

After the engaging convex portions 16 and 16 enter the upper end side of the engaging concave portions 26 and 26, the end portion S2 of the stroke S (the position where the engaging convex portions 16 and 16 are locked to the lower ends of the engaging concave portions 26 and 26). When the engaging protrusions 16 and 16 are further inserted into the hook 12 in the section S12 up to (see FIG. 7C), the free end portion 12a of the hook 12 protrudes in the vicinity of the end portion S2 of the stroke S. It starts to come into contact with the portion 27, and after that, it is sandwiched between the wall surface side fixing plate 21 and the protruding portion 27. Then, the engaging protrusions 16 and 16 are locked to the lower ends of the engaging recesses 26 and 26, and both metal fittings 10 and 20 are firmly connected in this state (see FIG. 6C). In this connected state, the lower end of the hook 12 is sandwiched between the wall surface side fixing plate 21 and the projecting portion 27, and the receiving plate 24 is sandwiched between the panel side fixing plate 11 and the hook 12, so that the wooden panel 30 There is no rattling in the thickness direction of the plate, and the pinching pressure also functions to prevent it from coming off in the vertical direction.

On the other hand, when the panel with metal fittings 50 once attached is removed from the outer wall surface 40 for reasons such as maintenance, it is only necessary to lift the panel with metal fittings 50 on the upper side upward in order.

As a result, the hook 12 is lifted in the order of the sections S12, S11, and S10 in the reverse order of the above-mentioned order, and finally the hook 12 is separated from the hook receiver 22.

When fixing the panel with metal fittings 50 in multiple stages, if the upper allowance for the panel with metal fittings 50 is secured, the panel 50 with metal fittings on the upper side and the panel with metal fittings 50 on the lower side can be raised. There is no need to pay for it. This is because by removing the upper metal fitting panel 50, it is possible to secure a rise allowance for the lower metal fitting panel 50.

As described above, according to the present embodiment, when the wooden panel 30 is detachably fixed to the outer wall surface 40, the receiving metal fitting 20 fixed to the outer wall surface 40 and the hook fixed to the wooden panel 30 By using the metal fitting 10, it is possible to perform the attachment work and the removal work by moving the wooden panel 30 up and down.

Therefore, the attachment work for attaching the wood panel 30 and the removal work for removing the attached wood panel 30 become much more efficient.

In particular, since the hook 12 of the present embodiment hangs down in a cantilever shape, it is introduced into the hook receiver 22 of the outer wall surface 40 by the action of lowering the wooden panel 30 downward. Therefore, since the weight of the wooden panel 30 can be used for the mounting work, the efficiency is remarkably improved and the mounting work becomes easier as compared with the bolt insertion work as in the conventional technique.

Further, in any of the replacement work of the wooden panel 30 attached to the outer wall surface 40, the set metal fittings A are all operated in a predetermined position on the outer wall surface 40 or in a state of being fixed to the back surface of the wooden panel 30. It can be performed. Therefore, it is not necessary to attach / detach the fastening member such as a bolt at a high place, and there is no possibility that the fastening member such as a bolt separated from the wooden panel 30 may fall during the work.

In addition, in the present embodiment, since the hook 12 is inserted and removed in the opening 22a of the hook receiver 22 in a loosely fitted state, the operator can easily insert the hook 12 into the hook receiver 22 and smoothly insert the hook 12 into the hook receiver 22. can do. Further, in the present embodiment, a pair of side plates 25 are integrally formed on both side portions of the receiving plate 24, and at least the upper end portion 25a of the pair of side plates 25 is formed on the wall surface by, for example, brazing or spot welding. Being fixed to the side fixing plate 21, the opening 22a of the hook receiver 22 provides a solid mechanical structure. Therefore, even if a twist or the like occurs when inserting the hook 12 while searching the hook receiver 22, sufficient durability can be exhibited, and the hook receiver 22 does not follow the insertion / removal operation of the hook 12. Therefore, the removal operation becomes easier.

On the other hand, in the section S12 of FIG. 7C, at the position where the hook 12 is inserted up to the end portion S2 of the stroke S, the protruding portion 27 elastically presses the hook 12 inside the hook receiver 22. Therefore, although the shape and dimensions of the hook 12 are set so that the hook 12 is inserted and removed at intervals, the rattling of the wood panel 30 in the thickness direction is regulated together with the rattling in the vertical direction.

Further, in the present embodiment, the hook 12 is inserted into the opening 22a at intervals (or the difference represented by G2-t1) in the plate thickness direction, and the protrusion amount P2 of the protrusion 27 is described above. It is set in the range of 125% to 150% of the interval (G2-t1) (see FIG. 3B). Therefore, in the present embodiment, the hook 12 can be inserted and removed without any trouble, and the hook 12 can be reliably pressed to regulate the rattling in the panel thickness direction.

Further, in the present embodiment, the engaging convex portion 16 formed on either one of the hook 12 and the receiving plate 24 and the engaging convex portion 16 formed on either one of the hook 12 and the receiving plate 24 are formed and engaged with the engaging convex portion 16. It is provided with an engaging recess 26 that defines the end portion S2 of the stroke S. Therefore, in the present embodiment, the heights of the fixed wooden panels 30 can be made uniform by engaging the engaging convex portion 16 and the engaging concave portion 26. Therefore, the operator can easily fix the wooden panel 30 to the outer wall surface 40 by simply inserting the hook 12 into the hook receiver 22 of the metal fitting 20 from top to bottom. Moreover, even when constructing a specification in which one exterior design is composed of a plurality of wooden panels 30, the heights of the adjacent wooden panels 30 can be precisely aligned with each other.

On the other hand, when removing the wood panel 30, it is only necessary to grasp the wood panel 30 and lift it upward. As a result, the engaging protrusion 16 and the engaging recess 26 are disengaged, and the hook 12 comes out above the hook receiver 22.

Further, in the present embodiment, the engaging recesses 26 and 26 are formed on the receiving plate 24 so as to lock the engaging convex portions 16 and 16 on the upper end side of the protruding portion 27, and the engaging convex portions 16 are formed. , 16 are formed in a pair of hemispheres arranged side by side in the width direction of the hook 12. Therefore, in the present embodiment, the engaging protrusions 16 and 16 formed in a hemisphere and forming a pair are locked to the engaging recesses 26 and 26, so that the engaging protrusions 16 and 16 and the engaging recesses 26 The contact area with 26 can be reduced. Moreover, the receiving plate 24 holds the hook 12 at three points by the protruding portion 27 and the two engaging convex portions 16 and 16 that are locked to the engaging concave portions 26 and 26 on the upper end side of the protruding portion 27. Therefore, a stable support structure can be obtained, and the support structure of the hook 12 becomes more solid. Even when the engaging protrusions 16 and 16 are paired, it is not always necessary to pair the engaging recesses 26 and 26. If possible, it may be one hole extending in the width direction in which both engaging protrusions 16 and 16 can be locked.

Further, in the present embodiment, the engaging recess 26 extends vertically, and the start end portion S1 side of the stroke S is set to a size (width W23) that allows the engaging convex portion 16 to be loosely fitted, and the end of the stroke S. It is provided with a tapered guide surface 26a that guides the engaging convex portion 16 so that the hook 12 is positioned to the left and right at the end portion of the stroke S by becoming narrower as it advances toward the portion S2. Therefore, in the present embodiment, until the engaging convex portion 16 reaches the end portion S2 of the stroke S of the hook 12, it can loosely fit with the engaging concave portion 26 and move with a small resistance. Therefore, the insertion / removal work becomes easy. Therefore, the opening width W22 of the hook receiver 22 and the opening width W23 on the upstream side of the engaging recess 26 can be set large to obtain an insertion / removal structure having less resistance and higher workability. Moreover, the opening width W22 of the hook receiver 22 may be set larger than the width W11 of the hook 12 (see FIG. 3C), or the opening width W23 on the upstream side of the engaging recess 26 (see FIG. 3B). Even if it is set to be large, the engaging convex portion 16 can be locked at the end portion S2 of the stroke S, and the unevenness of the vertical height between the wooden panels 30 can be eliminated.

Further, in the present embodiment, the engaging recesses 26 and 26 are holes penetrating the receiving plate 24. Therefore, in the present embodiment, the engaging recesses 26 and 26 can be easily formed by drilling the corresponding portions of the receiving plate 24 during press working.
