  The construction structure of the decorative member on the building outer wall described in Patent Document 1 has the advantage that the four circumferences of the opening can be easily decorated with the decorative member having the same shape. However, the fastening part of the decorative member to the building outer wall part is only the engaging part of one engaging groove formed on the back surface and one locking claw of the fastening metal fitting engaged therewith. It lacks stability. Therefore, in actual construction, as shown in FIG. 9, an adhesive 23 is partially interposed between the back surface of the decorative member 1 and the building outer wall 20, and the fixing force by the adhesive is also used together. Yes. However, when the decorative member 1 is fastened, it is a large work amount to apply the adhesive one by one. Therefore, a construction structure that can obtain a stable suspended and fixed state without using the adhesive is desired.

  The present invention has been made in view of the circumstances as described above, and further improved the decorative member to the outer wall of the building, which is capable of hanging and fixing the decorative member to the outer wall of the building in a more stable posture. The purpose is to provide a construction structure. Moreover, it aims at providing the decorative member used there.

The construction structure of the decorative member on the outer wall of the building according to the present invention is such that the decorative member is provided with a hanging groove composed of two engaging grooves inclined on the back side in the direction in which the back sides are close to each other. As the mounting bracket, one having two locking claws that engage with the hanging groove of the decorative member is used, and the mounting bracket is bent from the lower end of the substrate and the substrate and inclined upward and forward. A lower locking claw that is one of the two locking claws, and an upper locking claw that is the other of the two locking claws bent from the upper end of the substrate and inclined downward and forward, The lower locking claw and the upper locking claw have different inclination angles, and the inclination angle of the lower locking claw is larger than the inclination angle of the two engagement grooves of the suspension groove. There, and the inclination angle of the upper locking claw is a small inclination angle than the inclination angle of the engaging groove of the two rows of the hanging groove Ri, the fastening member is fixed to the building outer wall, in a state of engaging the engaging groove of the two rows of the hanging groove in engagement claws of Article 2 of the fixed fastening member The decorative member is suspended and fixed to an outer wall portion of a building.

  In the present invention, as the decorative member, all the ceramic-type outer wall materials having a substantially rectangular shape that have been conventionally used as the outer wall material of buildings can be used, but the thickness is increased in order to provide a profound feeling. It is particularly effective to use the ceramic industry outer wall material as a decorative member. The surface handle is also optional and is not limited.

  At the time of construction, the fastening member is fixed to the place where the decoration member on the outer wall of the building is to be fastened by an appropriate means such as a screw, and the decorative member is attached to the two locking claws of the fixed fastening member. The two engaging grooves of the hanging groove formed on the back surface of the hook are engaged. This engagement work may be a method of sliding the decorative member along the latching claw from the side, but it is desirable to carry out from the front side of the fixed fastening bracket in order to eliminate restrictions due to the work environment. This can be done easily by forming the engagement groove somewhat wider and adjusting the inclination angle of the engagement groove and the inclination angle of the locking claw as appropriate.

  The two engaging grooves that form the hanging groove run in parallel with a certain interval, and the back sides are inclined in a direction approaching each other. The claw is in an engaged state as if the two engaging grooves were gripped from above and below. As a result, the decorative member is firmly fixed to the building wall surface in a suspended state, and a desired stable fixed state can be obtained without depending on the adhesive force of the adhesive. Thereby, the application | coating operation | work of an adhesive agent can be abbreviate | omitted. Of course, depending on the situation, a fixing force by an adhesive may be used in combination.

  As the decorative member, the first hanging groove having the above-described configuration is preferably formed so as to extend along the long side at the substantially central portion of the left and right short sides, depending on the location to be fastened. One in which two second hanging grooves are formed along the left and right short sides, or one having both the first hanging groove and the second hanging groove, etc. Can be used.

  The decorative member in which the first hanging groove is formed along the long side is a decorative member suitable for horizontal stretching, and is horizontally stretched along the upper and lower edges of an opening such as a window. Sometimes, it is possible to suspend and fix a decorative member of the same shape at both positions simply by turning it 180 °. Moreover, the decorative member of this form is also suitably used for a horizontal decorative portion that goes around the building wall including the upper end of the balcony.

  The two decorative members formed so that the second hanging grooves are along the left and right short sides are decorative members suitable for vertical stretching, and one of the two second hanging grooves. By engaging with the latching claw of the fastening bracket, it is possible to fix the suspension in a vertically stretched state. In addition, for example, when vertically extending along the left and right side edges of an opening such as a window, the decorative member having the same shape is inverted by 180 °, and the fastening member is engaged with the other side of the second hanging groove. By engaging with the pawls, the same decorative member can be suspended and fixed at both the left and right side edges in a vertically stretched state.

  When a decorative member having both the first hanging groove and the second hanging groove is used, the same decorative member is inverted by 180 ° or 90 ° to thereby change the size of the opening of the window or the like. It becomes possible to suspend and fix the entire circumference.

That is, the present invention is a construction structure of a decorative member around the opening of a window or the like in the outer wall portion of a building. A first hanging groove made of a groove is formed along the long side, and two second hanging grooves made of similar two engaging grooves are made along the left and right short sides. Using the decorative member formed, and as a fastening metal fitting, provided with two locking claws engaging either one of the first and second hanging grooves formed on the back surface of the decorative member The fastening bracket used is a substrate, a lower locking claw that is one of the two locking claws that bends from the lower end of the substrate and is inclined upward and forward, and a lower front bent from the upper end of the substrate. An upper locking claw that is the other of the two locking claws inclined to the bottom, and the lower locking claw and the upper locking claw, Oblique angle are different, and the inclination angle of the lower engaging claw, a large inclination angle than the inclination angle of the engaging groove of the two rows of the hanging groove, and the inclination angle of the upper locking claws are The angle of inclination is smaller than the angle of inclination of the two engaging grooves of the hanging groove , and the fastening metal fittings have their upper pawls at the upper edge portion and lower edge portion of the opening. And fixed along the upper and lower edges in a posture parallel to the lower edge, and the fastening metal fittings on the right and left edge portions of the opening are perpendicular to the right and left edges. The decorative member is fixed along the right edge and the left edge in a posture to be fixed, and the fastening member fixed along the upper edge has the decorative member in a posture in which the first hanging groove is engaged with the engaging claw. It is suspended and fixed in a horizontal state, and the fasteners fixed along the lower edge have the same shape. The decorative member is suspended and fixed in a horizontal state in a posture in which the vertical direction is reversed and the first hanging groove is engaged with the engaging claw, and the fastening bracket fixed along the right edge side includes The decorative member is suspended and fixed in a vertically stretched state in a posture in which one of the second engagement grooves is engaged with the engagement claw, and has the same shape as the fastening bracket fixed along the left side edge side. The decoration on the outer wall of the building is characterized in that the decorative member of the building is suspended and fixed in a vertically stretched state in a posture in which the vertical direction is reversed and the other engagement groove is engaged with the engagement claw. The construction structure of a member is disclosed.

  In the construction structure described above, a long bracket can be used as the horizontal mounting bracket, and it can be easily and stably fixed to the outer wall of the building. However, since the fastener for vertical tension is narrower than the short side width of the decorative member, sufficient stability may not be obtained when it is fixed to the outer wall. In such a case, it is recommended to use a fastener having a shape having a long substrate in the vertical direction and having two locking claws formed in the substrate. By using the vertical fastening bracket in this form, the vertically stretched decorative member can be stably suspended and fixed.

Furthermore, the present invention provides a rectangular decorative member to the building outer wall used for the construction structure of the decorative member on the building outer wall as described above, from the two engagement grooves inclined on the back side in the direction in which the back sides are close to each other. The first suspension groove is formed so as to extend along the long side at substantially the center of the short sides on the left and right sides, and the second suspension groove composed of two similar engagement grooves is provided. A decorative member characterized in that two decorative members are formed along the left and right short sides is also disclosed as a reference form .

  According to the present invention, even a decorative member having a thickness and a heavy feeling can be securely fixed in a suspended state to the outer wall of a building or the periphery of a building opening without depending on the adhesive. Is possible.

  Hereinafter, a construction structure of a decorative member on a building outer wall according to the present invention and a decorative member used therewith will be described based on embodiments with reference to the drawings. FIG. 1 is an external perspective view of a building in which a decorative member is constructed according to the present invention, and a ceramic-type outer wall material (siding board) 20 is attached to the entire outer wall portion of the building, and a part of the outer wall portion. Further, ceramic-type outer wall materials having a surface handle different from the outer wall material 20 and having a large thickness are fixed as decorative members 60, 70, 80, and 90. The building outer wall may be a mortar wall instead of the outer wall material 20 attached, and the construction structure of the decorative member according to the present invention can be applied to an existing mortar wall.

  An outer wall portion A shown in FIG. 1 is a peripheral portion of an opening of a window of the building, and a construction structure according to the present invention is applied to the portion as described later, and the decorative member 60 is suspended and fixed. . Further, the outer wall portion B is a horizontal decorative portion that goes around the building outer wall including the upper end portion of the balcony, and the decorative member construction structure according to the present invention is applied to this portion, and the decorative members 70 and 80 are provided. Hanging and fixed. An appropriate decorative member 90 is fastened by an appropriate means to an outer wall portion that is a corner portion of the building, that is, an outer corner portion where the outer wall surfaces intersect at a right angle.

  Hereinafter, the construction structure of the decorative member according to the present invention will be described using the region of the outer wall portion A as an example. 2 is a perspective view showing an example of a decorative member 60 to be fastened, FIG. 2a is a view seen from the front surface 61 side, and FIG. 2b is a view seen from the back surface 62 side. The decorative member 60 has a rectangular shape as a whole, and the decorative member shown in the figure is not indispensable, but an appropriate uneven pattern is formed on the surface 61 side, while the upper end (one of the four sides) 63. In addition, a decorative shape is realized by forming appropriate irregularities facing upward. The back surface 62 is a flat surface.

  On the back surface 62, one first hanging groove 64 and two second hanging grooves 65, 66 are formed. The first hanging groove 64 is formed at the center of the left and right short sides 60a of the decorative member 60 so as to extend along the long side 60b, and the end 64c on the depth side (that is, the surface 61 side). Are formed by two parallel engaging grooves 64a and 64b inclined at an angle equal to the direction in which they are close to each other (in this example, 60 ° from the plane of the back surface 62). Similarly, the second suspension grooves 65 and 66 are also two parallel engagement grooves inclined at an angle equal to the direction in which the end portions on the depth side are close to each other (60 ° from the plane of the back surface 62 in this example). 65a, 65b and 66a, 66b, and one second hanging groove 65 is formed in parallel to the short side 60a1 at a position that is inside a certain distance from one short side 60a1. In addition, the other second suspension groove 66 is also formed in parallel with the short side 60a2 at a position that is located at the same distance from the other short side 60a2.

  The upper ends of the second suspension grooves 65 and 66 are preferably configured not to penetrate the upper end 63 of the decorative member 60 as shown in the figure. This is because the upper end 63 of the decorative member 60 is exposed to the outside when fastened to the outer wall, so that the design of the portion is not deteriorated.

  FIG. 3 shows an example of a first fastener (horizontal fastener) 50 used when the decorative member 60 is suspended and fixed in a horizontally stretched state. The horizontal mounting bracket 50 is processed from an appropriate metal plate such as a gallium steel plate, and is bent from the lower end of the substrate 51, bent downward from the lower end of the substrate 51, and inclined from the upper front to the upper end of the substrate 51. The upper locking claw 53 is bent and inclined downward and forward. As shown in FIG. 3 b, the inclination angle of the lower locking claw 52 and the upper locking claw 53 with respect to the substrate 51 is different, and the inclination angle of the lower locking claw 52 is two lines formed on the back surface 62 of the decorative member 60. The inclination angle of the engagement grooves 64a and 64b is slightly larger than the inclination angle (60 °) (62 ° in this example), and the inclination angle of the upper locking claw 53 is larger than the inclination angle of the two engagement grooves. The angle is a little small (58 ° in this example). The vertical width of the substrate 51 is substantially the same as the interval on the back surface 62 of the two engagement grooves 64a and 64b (interval between the central portions of the grooves). Although not shown, in some cases, in order to stabilize the fixing to the outer wall portion, the substrate 51 may have a shape that extends further vertically from either one or both of the lower locking claw 52 and the upper locking claw 53. .

  As will be described later, since the lower locking claw 52 is a part that mainly supports the weight of the decorative member 60 to be suspended and fixed, the steel plate is folded twice as shown to give strength. The board 51 is formed with an appropriate number of screw holes 54 used for fixing to the building side with screws or the like. However, the screw holes 54 are omitted, and screws or nails are directly attached to the board 51 during construction. You may make it fix by driving in.

  Next, an example of a construction structure in which the decorative member 60 is horizontally stretched on the upper edge portion and the lower edge portion of the opening P of the building window by using the horizontal fastening metal fitting 50 will be described with reference to FIGS. I will explain. 4 is a perspective view showing a part of the upper edge side of the opening P, and FIG. 5 is a cross-sectional view taken along the line VV of FIG. FIG. 6 is a perspective view showing a part of the lower edge side of the opening P. FIG. In this example, an outer wall portion (outer wall plate or mortar wall) 20 around a window opening P of a building has a window frame sash 21 fitted and fixed in advance, and the upper and lower edges of the window frame sash 21 are decorated. The member 60 is fastened in a horizontal state.

  At the time of construction, first, the horizontal fastening bracket 50 is positioned parallel to the upper edge of the window frame sash 21, and the screw 22 is inserted into the screw hole 54 and fixed by screwing. The mounting height of the horizontal mounting bracket 50 is such that when the decorative member 60 is suspended and fixed using the locking claws 52 and 53, the flat long side below the decorative member 60 is fixed. 60b comes into contact with the upper edge of the window frame sash 21 or has a height slightly above it. Note that the horizontal mounting bracket 50 is formed to have an appropriate length, but when the horizontal width of the window frame sash 21 is long, a plurality of horizontal mounting brackets 50 are fixed in a horizontal direction and short. In some cases, cut to an appropriate length on site to fit it.

  The rear surface 62 of the decorative member 60 is opposed to the front surface side of the fixed horizontal fastening metal fitting 50 with the upper end edge 63 positioned at the upper position, and is pushed upward and obliquely upward from below, so that The upper engaging groove 64a constituting the first hanging groove 64 is hooked. When the decorative member 60 is pushed upward from the posture and then pressed against the side fastening bracket 50, the lower locking claw 52 enters the lower engaging groove 64b so as to rub. As described above, the inclination angle of the upper locking claw 53 is slightly smaller than the inclination angle of the engagement groove 64a, and the inclination angle of the lower engagement claw 52 is slightly larger than the inclination angle of the engagement groove 64b. Therefore, this engagement work is easy, and after the engagement, the first hanging groove 64 of the decorative member 60 is firmly held from above and below by the two locking claws 52 and 53. Therefore, the decorative member 60 is stably suspended and fixed as it is.

  As described above, a stable suspended fixed state can be obtained without using an adhesive for fastening the decorative member 60 to the outer wall portion. Of course, the adhesive 23 made of a modified silicone or the like is applied to the back surface 62 of the decorative member 60 at appropriate intervals in advance for suspension fixing, and the outer wall material 20 is applied with the adhesive force by the adhesive together with the suspension fixing. It can also be used together as a fastening force of the decorative member 60 against the above.

  FIG. 6 shows an example of a construction structure in which the same decorative member 60 is horizontally stretched on the lower edge portion of the opening P of the window of the building using the horizontal mounting bracket 50. In this case as well, it can be performed in the same manner as in the case of construction on the upper edge portion of the window opening P described above. That is, the same horizontal fastening bracket 50 as described above is positioned parallel to the lower edge of the window frame sash 21 and fixed. Then, the same decorative member 60 as described above is turned up and down by 180 ° as shown in FIG. 6 so that the concavo-convex portion of the upper end 63 comes to the lower side. Then, the upper locking claw 53 is hooked into the engaging groove 64b, which is positioned higher in that posture, and pushed upward further from that posture, and then the decorative member 60 is Press against the side mounting bracket 50 side. Thus, the lower locking claw 52 enters the engaging groove 64a positioned at the lower position, and the decorative member 60 is suspended and fixed to the lower edge portion in a horizontally stretched manner in the same manner as the upper edge portion. Also in this case, if necessary, a fixing force by an adhesive can be used in combination.

  Next, an example of a construction structure when the same decorative member 60 is vertically stretched on the left and right side edge portions of the opening P of the building window will be described with reference to FIGS. In this case, as the fastening bracket, the above-described lateral fastening bracket 50 cut into a short lateral width can be used as the vertical fastening bracket, but since it is narrow, it is attached to the outer wall portion. Since the fixation may lack stability, a second fastening member as shown in FIG. 8 is preferably used as the vertically attached fastening member 55. The vertical fastening bracket 55 is processed from an appropriate metal plate such as stainless steel, and is bent from the lower end of the substrate 56 in the up and down direction, like the horizontal fastening bracket 50. And an upper locking claw 58 that is partly cut and raised from the middle of the substrate 56 and bent forward and inclined downward and forward.

  The inclination angles of the lower locking claw 57 and the upper locking claw 58 with respect to the substrate 56 are different from the case of the above-described horizontal mounting bracket 50, and as shown in FIG. The inclination angle is the inclination angle of the two engagement grooves 65a (66a) and 65b (65b) constituting the second suspension groove 65 (66) formed on the back surface 62 of the decorative member 60 (in this example, The inclination angle of the upper locking claw 58 is slightly smaller than the inclination angle of the two engaging grooves (58 ° in this example). ). The distance between the lower locking claw 57 and the upper locking claw 58 is the distance between the two engagement grooves 65a (66a) and 65b (65b) on the back surface 62 (the distance between the central portions of the grooves). ) Is almost the same. In addition, as with the horizontal mounting bracket 50, the lower locking claw 57 is double-stretched to give strength.

  Furthermore, the board 56 is formed with an appropriate number of screw holes 59 used for fixing to the building side with screws or the like, but in this case as well, the screw holes 59 are omitted and screws or nails are directly attached during construction. The substrate 56 may be driven and fixed.

  FIG. 7 shows a case where the decorative member 60 used for the horizontal stretch is vertically stretched along the right edge of the window opening P (window sash 21) of the building using the vertical mounting bracket 55. Thus, at a required height position near the right edge of the opening P of the window, the vertical fastening bracket 55 is placed with its locking claws 57 and 58 orthogonal to the right edge using screws or the like. Fix it. Then, for example, the decorative member 60 is set to a posture in which the decorative member 60 is rotated 90 ° clockwise from the posture of being horizontally stretched on the upper edge side, the uneven portion of the upper end 63 is on the right side, and the flat lower edge 60b side is the opening portion. The rear surface of the P (window sash 21) is opposed to or directly close to the right edge of the P (window sash 21), and is opposed to the vertical fastening bracket 55.

  Then, as in the case of the horizontal tension, the upper engagement groove 66a constituting one second suspension groove 66 is hooked on the upper engagement claw 58 of the fixed vertical attachment 55, and After pushing up further from the posture, the decorative member 60 is pressed against the vertical fastening bracket 55 side. As a result, the lower locking claw 57 enters the lower engaging groove 66b, and the decorative member 60 is suspended and fixed to the right edge of the opening P in a vertically stretched state. Also in this case, the fixing force by the adhesive 23 can be used together if necessary.

  In addition, although illustration is abbreviate | omitted, the decoration member 60 can be vertically stretched in the left part of the opening part of the window of a building using the vertical attachment bracket 55. FIG. In that case, the vertical fastening bracket 55 is fixed at a required height position in the vicinity of the left edge of the opening P in the same manner as in the right portion. Then, for example, the decorative member 60 is set to a posture in which the decorative member 60 is rotated 90 ° counterclockwise from the posture of being horizontally stretched on the upper edge side, and the flat lower edge 60b side is the left edge of the opening P (window sash 21). It is in a state of being in close contact with or in close proximity. Then, the decorative member 60 is used for the vertical tension in a state where the upper engaging groove 65a constituting the other second suspension groove 65 is hooked on the upper latching claw 58 of the fixed vertical fastening bracket 55. Press against the fastener 55 side. Thereby, the lower locking claw 57 enters the engaging groove 65b positioned at the lower position, and the decorative member 60 is suspended and fixed to the left edge of the opening P in a vertically stretched state. Of course, also in this case, if necessary, a fixing force by an adhesive can be used in combination.

  Although not shown in the figure, only the first hanging groove 64 is formed on the back surface as a decorative member in the case of aiming only for the horizontal stretch as in the outer wall portion B which is the decorative region in FIG. The decorative member 70 may be used, and if only the vertical tension is intended, a decorative member in which both or only one of the second hanging grooves 65 and 66 is formed on the back surface may be used.

  Further, in the decorative member shown in FIG. 2, the first hanging groove 64 is formed at the substantially central portion in the short direction when the same decorative member is suspended and fixed on the upper edge side and the lower edge side. In order to facilitate the positioning of the horizontal mounting bracket, the two second hanging grooves 65 and 66 are formed at an inner position by a substantially equal distance from the short side. The purpose of the present invention is to facilitate the positioning of the vertical fastening bracket when the member is suspended and fixed on the right edge side and the left edge side. Of course, it is not an essential configuration for achieving the above.
