Description

  The present invention relates to a structure for fixing an exterior decorative material used for a building frame, and in particular, to fix a bifurcated decorative pillar fixed around a structural pillar, a headboard fixed to an upper portion of a veranda or the like, using a mounting bracket. Concerning structure.

  Conventionally, in order to fix an exterior decorative material to a structure, various methods using a mounting bracket have been proposed. Such a mounting bracket has two types of fixing means: a pair fixing means for fixing the bracket itself to the structure and a pair fixing means for fixing the exterior cosmetic material to the bracket. Generally, as the anti-decorative material fixing means, hook-shaped engaging means in which one concave portion or convex portion is engaged with the other convex portion or concave portion is used (see, for example, Patent Document 1).

Japanese Utility Model Publication No. 6-25445

  However, in the conventional methods including the method of Patent Document 1, only one set of hook-shaped engaging means is provided at one position of the engaging portion. Moreover, even if it has two engaging means in one engaging part, the dimension was the same.

  On the other hand, exterior decorative materials include resins, natural wood cement, artificial wood materials, painted iron plates, ceramics such as cement and ceramics. Ceramic-type exterior decorative materials generally have a large thickness, so that the mass is heavy, and the dimensional error of the finished product is large compared to other structures. Therefore, the ceramic-type exterior decorative material is properly engaged with the state temporarily fixed by the frictional force between its own weight and the engaging means even if it is not engaged with the bowl-shaped engaging means as in Patent Document 1. It was difficult to confirm the state of being fixed permanently after construction.

  In addition, there may be a case where the elastic piece of the engaging means can be judged by a sound generated when the outer decorative material is engaged and returned from the pressed state, but the sound is not always clearly generated at the time of work. In addition, the worker may not be able to confirm the sound because it may be difficult to hear the sound due to individual differences in hearing, or the surrounding noise may not be heard greatly.

  Such ceramics exterior cosmetics, which were thought to have been fixed at the time of construction, may actually be temporarily fixed, and temporarily fixed ceramics exterior cosmetics are due to earthquakes. There is a possibility of disengagement due to a shift or aging of the engaging means.

  Therefore, in order to solve the above-mentioned problems, the present invention provides a fixing structure for an exterior cosmetic material for securely fixing a ceramic-type exterior cosmetic material having a relatively large dimensional error to a building frame using a mounting bracket. The purpose is to provide.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a fixing structure for an exterior decorative material according to the present invention will be described in detail with reference to the drawings.

<First Embodiment>
In the case where a decorative column is provided on the entrance porch column of the house which is the first embodiment of the exterior decorative material of the present invention, more specifically, when the two-divided column body 11 is fixed on the structural column 91 using the mounting bracket 31. The fixing structure and method will be described with reference to FIGS. 1A, 1B, 2, and 3A to 3C.

  The decorative pillar 1 is used in a building, for example, from the structural pillar 91 (building frame) that actually supports the weight of the structure for reasons such as enhancing the appearance stability or improving the appearance of the pillar. It is a pillar having a large cross section with a hollow portion 95 inside and added around it, and a decorative finish such as a decorative coating on the outer peripheral surface. The entrance porch is a space that is generally raised by several steps from the approach portion under the eaves in front of the entrance door. The decorative pillar 1 is provided by vertically connecting the upper part of the base part of the entrance porch and the lower part of the bag. In addition, the decorative pillar 1 may be used for a veranda or the like.

  The two-divided column body 11 is a cement-based extrusion molded body in which the decorative column 1 used for a building such as a house as described above is vertically divided into two equal parts, and the specific gravity is about 0.7 to 1.5. Consists of. A cavity (hollow portion 95) is formed inside the two-divided pillar body 11 so as to include the structural pillar 91 of the building. The two-divided columnar body 11 that is mounted to face the structure column 91 is formed so as to include concave portions 97 that engage with the mounting bracket 31 on both side portions 14 and 15 with the cavity portion 95 interposed therebetween.

  Further, the first side portion 14 and the second side portion 15 of the inner peripheral surface of the two-divided column body 11 are side portions that face each other with the cavity portion 95 interposed therebetween, and a concave portion is formed in each of the side portions 14 and 15. 97 is formed. The shape of the recess 97 can be engaged with the elastic engagement portion 32 so that the two-divided column body 11 can be fixed by being engaged with the elastic engagement portion 32 described later, and the direction of engagement is the reverse direction. It is formed in such a shape. In this way, the two-divided column body 11 is made into a plurality of locations, and the two-segmented column body 11 is changed to the structural column 91 (building housing) by reversing the engaging direction of the elastic engagement portions 32 in the two recessed portions 97. ).

  The two two-divided column bodies 11 arranged around one structural column 91 are arranged so as to face each other with the structural column 91 interposed therebetween. The gap between the two two-divided column bodies 11 is usually filled with a caulking agent or the like for filling a hole or concealed with a dry joint material. The caulking agent or the like has an adhesive action on the adherend surface when solidified, and becomes a kind of adhesive.

  The mounting bracket 31 is formed so that the two-divided column body 11 can be fixed to the structural column 91 by using two mounting brackets 31 at one position across the structural column 91 of the building. The two mounting brackets 31 are formed in the same shape so that they can be fixed by screwing the fixing screw 100 into the fixing screw hole 81 with the structural column 91 of the building interposed therebetween. The fixing screws 100 are attached to a plurality of places including the place. The interval for installing the mounting bracket 31 is provided in the vertical direction of the structural column 91, for example, at an interval of about 700 mm.

  The mounting bracket 31 is formed by performing press molding and bending molding on a stainless steel plate (for example, SUS430) using a mold. The mounting bracket 31 can be engaged with at least two recesses 97 of the two-divided column body 11 while pressing the inner peripheral side surfaces 14 and 15 of the two-divided column body 11 in the outer direction of the two-divided column body 11, and Each of the engaging directions is formed in an opposite direction, and has an elastic engaging portion 32 for positioning and fixing the two-divided column 11.

  The elastic engagement portion 32 is formed linearly from a stainless steel plate with an open end at the end facing the two-divided column 11, and therefore elastic force is exerted in a direction perpendicular to the plane as a leaf spring. Have. Further, the open end side of the elastic engagement portion 32 is divided into a plurality of branch portions by the slit 71, and is divided into a first branch portion 41 and a second branch portion 51 in the present embodiment.

  The slit 71 is provided between the first branch part 41 and the second branch part 51, and is longer than a length that allows each branch part 41, 51 to be individually elastically operated with respect to the recess 97 of the two-divided column 11. It is formed with the dimension. For example, even if one of the branch portions cannot engage with the concave portion 97 of the two-divided column 11, the length of the branch portions 41 and 51 can be individually elastically operated. It means that the length can be engaged with the concave portion 97 of the two-divided column 11 by elasticity without being influenced by it. More specifically, for example, even when the branch portion 41 is elastically compressed and approaches the structural column 91 side, the branch portion 51 does not receive any interlocking compression force and does not approach the structural column 91 side. It is the length from which each branch part 41 and 51 was fully separated.

  Further, the first branch portion 41 is formed with a length of a predetermined reference value, and the second branch portion 51 is formed shorter than the length of the predetermined reference value. Thereby, even when the 1st branch part 41 cannot be engaged with the recessed part 97 of the 2 division | segmentation column body 11, the 2nd branch part 51 can be engaged with the recessed part 97 of the 2 division | segmentation column body 11. FIG.

  The length that makes the second branch portion 51 shorter than the first branch portion 41 is preferably about 2 mm, for example. With regard to this length, for example, if the second branch portion 51 is made extremely shorter than the length of the predetermined reference value, it can be fixed, but a movable range is created after the fixing, resulting in rattling. On the other hand, if the second branching portion 51 is too close to the length of the predetermined reference value, there is no difference from the first branching portion 41, so that it may not be fixed in the same manner. It will disappear. As described above, since the problem occurs when the length dimension of the second branch portion 51 is set too short or too close to a predetermined reference value, the length between the first branch portion 41 and the second branch portion 51 is increased. The difference L1 needs to be set in an appropriate range such as around 2 mm.

  Further, the length of the predetermined reference value is, for example, a value or a design value defined in the specification, and can be engaged with the recessed portion 97 after drying of the two-divided column body 11 formed of a cement-based extruded body. Is the dimension set to. Further, a first engagement end portion 42 that engages with the recess 97 is integrally formed at the distal end portion of the first branch portion 41, and a first engagement portion that engages with the recess portion 97 is formed at the distal end portion of the second branch portion 51. Two engaging end portions 52 are integrally formed.

  The first branch portion 41 and the first engagement end portion 42 are formed in a bowl shape so that the first branch portion 41 and the first engagement end portion 42 can be engaged with, for example, the concave portion 97 of the two-divided column body 11. Similarly, the second branch portion 51 and the second engagement end portion 52 are also formed in a bowl shape so as to be able to engage with the concave portion 97 of the two-divided column body 11. The saddle shape includes the first engagement end portion 42 or the second engagement end portion 52 being independently a saddle shape, but in the present embodiment, the first branch portion 41 and the first engagement portion 31 in the mounting bracket 31 are the same. The entirety of the engagement end portion 42 or the entirety of the second branch portion 51 and the second engagement end portion 52 constitutes a bowl shape. The saddle mold engages with the recess 97 and the two-divided column 11 is fixed to the structural column 91.

  Two protrusions 62 are formed for one mounting bracket 31, and the two protrusions 62 are formed so as to be separated from each other by a dimension capable of sandwiching and holding one side of the square of the structural column 91. The opening 61 is an opening formed because the protrusion 62 has been punched.

  The mounting bracket 31 is formed by press molding, bending molding, or the like as described above, so that the manufacturing can be facilitated and the manufacturing cost can be reduced. Since the two mounting brackets 31 have the same shape, the manufacturing cost can be reduced. In addition, the number of parts can be reduced.

  The fixing screw hole 81 is a hole for attaching two mounting brackets 31 that are mounted to face each other with the structural column 91 interposed therebetween with a fixing tool, for example, the fixing screw 100. In the case where the fixing screw 100 is of a type in which a screw hole is made and tightened while cutting a groove, such as a drill screw or a tapping screw, it is not necessary to provide the fixing screw hole 81 in advance, and the mounting bracket 31 is screwed. Sometimes formed. In addition, when the fixing screw 100 is not a type that is tightened while cutting the screw groove, a screw groove is formed in advance inside the fixing screw hole 81. Further, when a bolt is used together with a nut as the fixing screw 100, it is not necessary to previously form a screw groove inside the fixing screw hole 81, and a simple circular opening may be used.

  The two mounting brackets 31 of this embodiment are respectively inserted into two opposing sides of the square of the cross section of the structural column 91, and the fixing screws 100 are inserted into the fixing screw holes 81 and tightened, whereby each mounting bracket 31 is a structural column. 91 is fixed. Next, it pushes in so that the 2 division | segmentation pillar 11 of the cross section square of the structural pillar 91 of FIG. Accordingly, the concave portion 97 of the two-divided column body 11 on the right side of the structural column 91 in FIG. 2 engages with the first engagement end portion 42 of the first branch portion 41, and the two-divided column body 11 becomes the structural column 91. Fixed. Next, the two-divided pillar body 11 on the left side of the square section of the structural column 91 in FIG. Accordingly, the concave portion 97 of the two-divided column body 11 on the left side of the structural column 91 of FIG. 2 tries to engage with the first engagement end portion 42 of the first branch portion 41, but the first branch portion 41 and the first The engagement end 42 is too long to engage. However, in the present embodiment, since the second branch portion 51 and the second engagement end portion 52 are formed shorter than the dimensions of the first branch portion 41 and the first engagement end portion 42, 2 Engagement end 52 engages with recess 97. As a result, the left-side divided column body 11 is also fixed to the structural column 91. FIG. 3A shows this state.

  Further, as shown in FIG. 3B, the two-column body 11 on the left side of the structural column 91 in FIG. 2 is first pushed and fixed so as to cover the left side of the structural column 91, and then the structural column in FIG. When the right two-divided column 11 of 91 is pushed in, the left and right are reversed. That is, the concave portion 97 of the two-divided column body 11 on the right side of the structural column 91 in FIG. 2 tries to engage with the first engagement end portion 42 of the first branch portion 41. The size of the end portion 42 is too long to engage. However, in the present embodiment, since the second branch portion 51 and the second engagement end portion 52 are formed shorter than the dimensions of the first branch portion 41 and the first engagement end portion 42, 2 Engagement end 52 engages with recess 97. As a result, the right two-divided column body 11 is also fixed to the structural column 91.

  In addition, as shown in FIG. 3 (c), there are cases where the two-divided column bodies 11 on the left and right sides of the structural column 91 in FIG. 2 are pushed and fixed so as to cover the left and right sides of the structural column 91 almost simultaneously by a plurality of personnel. Conceivable. In this case, as shown in FIG. 2, the concave portions 97 of the bifurcated column bodies 11 on the left and right sides of the structural column 91 of FIG. 2 are engaged with the first engagement end portion 42 of the first branch portion 41, As shown in FIG. 3B, when the concave portion 97 of the left split column body 11 and the second engagement end 52 are engaged as shown in FIG. In some cases, the concave portion 97 and the second engagement end portion 52 are engaged with each other, but as shown in FIG. 3C, the concave portion 97 and the second engagement end portion 52 of the bifurcated pillar body 11 on both the left and right sides. It is also conceivable that and are engaged. In any of the above cases, the two-divided column body 11 can be reliably fixed to the structural column 91 by using the mounting bracket 31 of the present embodiment.

  As described above, according to the fixing structure of the exterior decorative material according to the present embodiment, the structural column can be obtained by using the mounting bracket 31 according to the present embodiment even in the case of the ceramic-based two-divided column body 11 having a large dimensional error of the finished product. It can be securely fixed to 91, and the possibility of coming off due to an earthquake or a secular change of the engaging means can be reduced.

<Modification 1: First Embodiment>
In the first embodiment, the concave portion 97 is formed in each of the first side portion 14 and the second side portion 15 of the inner peripheral surface of the two-divided column body 11, and the structural column 91 is formed by the mounting bracket 31 engaged therewith. It can be fixed to. However, the present embodiment is not limited thereto, and the first side portion 14 and the second side portion 15 on the inner peripheral surface can be fixed to the structural column 91 by the mounting bracket 31 even when the convex portions are provided.

  Below, the modification 1 of 1st Embodiment is demonstrated using FIG. In the present embodiment, the two-divided column body 11 is provided with a convex portion 98 (FIG. 4A) or a convex portion 99 (FIG. 4B) that engages with the mounting bracket 31. The joint portion 32 engages with the convex portions 98 or 99 of the two-divided column body 11 while pressing the side surfaces 14 and 15 on the inner peripheral side of the two-divided column body 11 in the outer direction of the structural column 91. This is the same as in the first embodiment.

  Thus, even when the two-divided column body 11 of this modification is provided with a convex portion that engages with the mounting bracket 31, it can be reliably fixed to the structural column 91 by using the mounting bracket 31 of this embodiment. The possibility of detachment due to an earthquake or a secular change of the engaging means can be reduced.

<Modification 2: First Embodiment>
In said 1st Embodiment, the open end side of the elastic engagement part 32 is divided into 2 by the slit 71 into the 1st branch part 41 and the 2nd branch part 51, and, thereby, the ceramics type | system | group with a large dimensional error of a finished product It was shown that even the two-divided pillar body 11 can be securely fixed to the structural pillar 91 by the mounting bracket 31. However, in the first embodiment, the recess 97 is an alternative between being engaged with the first engagement end portion 42 and being engaged with the second engagement end portion 52. In that case, as described above, since the problem occurs even if the length dimension of the second branch portion 51 is set too short or too close to a predetermined reference value, the dimensional error of the finished product can be absorbed without rattling. Length setting is difficult. In the second modification, in order to facilitate the setting of the length dimension of the second branch part 51, the open end side of the elastic engagement part 32 is divided into three or four parts and fixed to the structural column 91. explain.

  5A shows a case where the open end side of the elastic engagement portion 132 is divided into three, and FIG. 5B shows a case where the open end side of the elastic engagement portion 232 is divided into four. 5A, the open end side of the elastic engagement portion 132 is divided into three first branch portions 141, second branch portions 151, and third branch portions 161 by slits 171 and 172. Has been. Since the difference in length between the first branch part 141 and the second branch part 151 is L1, and the difference in length between the second branch part 151 and the third branch part 161 is L2, Compared to twice the dimensional error of the finished product. Alternatively, by narrowing the range of each difference between L1 and L2, it is possible to absorb the dimensional error of the finished product without more backlash. However, since the contact area between each branch portion and the recess is reduced, it is necessary to divide the elastic engagement portion 132 within a range where each branch portion has sufficient strength.

  On the other hand, in the case of four divisions in FIG. 5B, the open end side of the elastic engagement portion 232 is provided with four first branch portions 241, second branch portions 251, and third branches by slits 281, 282, and 283. It is divided into a part 261 and a fourth branch part 271. The difference in length between the first branch part 241 and the second branch part 251 is L1, the difference in length between the second branch part 251 and the third branch part 261 is L2, and the third branch part 261 Since the difference in length from the fourth branch portion 271 is L3, it is possible to cope with a dimensional error of the finished product that is three times that of the first embodiment. Alternatively, by narrowing the range of each difference between L1 and L3, the dimensional error of the finished product can be absorbed without further backlash. However, also in this case, the contact area between each branch portion and the concave portion is reduced, so that it is necessary to divide the elastic engagement portion 232 within a range where each branch portion has sufficient strength.

  As described above, in this modification, the open end side of the elastic engagement portion is divided into three or more, and the lengths of the plurality of second branch portions are shorter than the predetermined reference value and are different from each other. In the case where the length is formed, the length of each second branch portion can be set in two or more stages by using the mounting bracket 31 of this embodiment. Even when the dimensional error of the finished product varies, it is possible to fix the second branch portion 51 having an appropriate length without rattling. Furthermore, even when the dimensional error of the finished product of the two-divided pillar body 11 is very large, it is possible to cope with the looseness after fixing by adjusting each length dimension of the second branch portion. That is, it is possible to deal with a wider dimensional error of the finished product, and to absorb the dimensional error of the finished product with less play.

<Third Embodiment>
Said 1st Embodiment demonstrated the case of the decorative pillar which is a ceramics-type exterior cosmetic material, and 2nd Embodiment demonstrated the case of the headboard which is a ceramics-type exterior cosmetic material. However, the fixing structure of the present invention is not limited to the decorative pillars and headboards. For example, a body insert (curtain board), a parting material, or a corner member, which is a ceramic exterior cosmetic material, is fixed on the outer wall surface of a building. The present invention can also be applied to a fixed structure. Hereinafter, with reference to FIGS. 7A, 7 </ b> B, and 7 </ b> C, a description will be given of a third embodiment in the case where the body insertion or the corner member is fixed on the outer wall surface of the building using the mounting bracket.

  The mounting bracket 431 of the present embodiment is installed on the outer wall surface 5 of the building, and is fixed by the fixing screw 100 through the fixing screw hole 81.

A screw fixing portion 481 for positioning and fixing the barrel 2 or the corner member 3 to the mounting bracket 431 while being screwed by the tapping screw 110 is provided.

  The elastic engagement portion 432 has a free end by slits 471 and 472 in a part facing the body 2 or the corner member 3 and is formed linearly, and is formed from a stainless steel plate, so that it is a leaf spring. It has elastic force in the direction perpendicular to the plane. In addition, the branch portion of the elastic engagement portion 432 has a plurality of branch portions, and is divided into a first branch portion 441 and a second branch portion 451 in this embodiment.

  The slit 471 is provided between the main body of the mounting bracket 431 and the first branch 441, the slit 472 is provided between the main body of the mounting bracket 431 and the second branch 451, and the slit 473 is It is provided between the main body portion of the mounting bracket 431 and the engaging portion 462. The slits 471 and 472 are formed with a dimension that is greater than or equal to the length that allows each branching portion 441/451 to be elastically operated with respect to the concave portion 497 of the trunk 2 or the corner member 3.

  The first branch portion 441 is formed with a length of a predetermined reference value, and the second branch portion 451 is formed shorter than the length of the predetermined reference value. Accordingly, even when the first branch portion 441 cannot be engaged with the recess 2 497 of the trunk 2 or the corner member 3, the second branch 451 can be engaged with the recess 497 of the barrel 2 or the corner member 3. The length that makes the second branch portion 451 shorter than the first branch portion 441 is set within an appropriate range such as a difference L5 = 2 mm or the like, as in the first and second embodiments.

  Further, the length of the predetermined reference value is also a value or a design value defined in the specification, for example, as in the first embodiment and the second embodiment, and the trunk 2 or the corner formed of the cement-based extruded body. The dimension is set so as to be able to engage with the recessed portion 497 after the member 3 is dried. Further, a first engagement end 442 that engages with the recess 497 is integrally formed at the tip of the first branch 441, and a first engagement with the recess 497 is formed at the tip of the second branch 451. Two engagement end portions 452 are integrally formed.

  The first branch portion 441 and the first engagement end portion 442 are formed in a bowl shape so as to be able to be engaged with, for example, the body 2 or the concave portion 497 of the corner member 3. Similarly, the second branch portion 451 and the second engagement end portion 452 are also formed in a bowl shape so as to be able to engage with the recess 2 497 of the trunk 2 or the corner member 3. The saddle shape also includes making the first engagement end portion 442 or the second engagement end portion 452 independently a saddle shape, but in the present embodiment, the first branch at the engagement portion 462 and the mounting bracket 431 is used. The entirety of the portion 441 and the first engagement end portion 442 or the entirety of the second branching portion 451 and the second engagement end portion 452 constitutes a bowl shape. The saddle mold engages with the recess 497, and the barrel 2 or the corner member 3 is fixed on the outer wall surface 5 of the building.

  The screw fixing portion 481 is bent with respect to the main body portion of the mounting bracket 431 so that the narrow angle between the screw fixing portion 481 and the mounting bracket 431 becomes an acute angle. This is because when the angle formed between the outer wall surface 5 of the building and the screw fixing portion 481 is an obtuse angle rather than a right angle, it is easier to secure a space for using tools at the work site of the building, and from a position parallel to the wall. This is because the working efficiency can be improved if there is a space with the wall rather than driving the fixture. Further, the screw fixing portion 481 has a bent portion 482 on the way to the end portion 483. This is because when the structure 411 of the trunk 2 or the corner member 3 is fixed to the screw fixing portion 481 while being cut by the tapping screw 110, the screw fixing portion 481 is prevented from escaping and is easily fixed. . The screw fixing portion bent at an acute angle is further bent twice so that the tip portion of the screw fixing portion is V-shaped so that the upper surface of the screw fixing portion 481 and the inside of the structure 411 are brought into contact with each other, not the end portion 483. It is also possible to make it.

  As described above, according to the fixing structure of the exterior decorative material of the present embodiment, even with the ceramic body torso 2 or the corner member 3 having a large dimensional error of the finished product, the mounting bracket 431 of the present embodiment is used. It can be reliably fixed on the outer wall surface 5 of the building, and the possibility of coming off due to an earthquake or secular change of the engaging means can be reduced. Also, Modification 1 and Modification 2 of the first embodiment can be similarly applied to this embodiment.
