Description

  The present invention relates to an outer wall material mounting bracket for attaching an outer wall material to a building and an outer wall material mounting method.

  Conventionally, when attaching the outer wall material of a flat plate building to the building frame via a base material such as a trunk edge or a stud, or directly connecting the outer wall material to each other and improving the appearance In many cases, for example, the end portions of the outer wall material are attached to each other in a state of abutting each other by a phased-up method. In the outer wall material mounting structure using such a phase-claw method, if the outer wall material is directly attached to the housing side material with a nail, the head of the nail is exposed to the outside, and it is necessary to hide the nail, If the outer wall material is fragile due to rust generation, the outer wall material will break when nailing, or the nailing must be done while supporting the outer wall material, so the workability is poor, etc. This causes various problems.

  Therefore, at present, the mounting bracket is attached to the building frame side material (base material or the frame itself) with nails or screws in a state where the mounting bracket is interposed between the outer wall materials, and the outer wall material passes through the mounting bracket. The construction method to attach to the frame side material is becoming common.

  In addition, as a specific aspect of the phase stacking method, a male part is provided at one end of one outer wall member, a female part is provided at the other end, and the female part and the male part of adjacent outer wall members are mutually connected. There is a method of fitting (see, for example, Patent Document 1). In such a construction method, there is a mounting bracket having both a male and female engaging portion that is engaged with the male and female portions of the adjacent outer wall material by one mounting bracket. in use.

  However, conventionally, when attaching the mounting bracket to the building frame side material, an operator must perform screwing or nailing operation of the mounting bracket on the building frame side material while holding both the long outer wall material and the mounting bracket. There was a problem that workability was bad.

  In general, outer wall materials of a certain standard size are manufactured at a factory and supplied to a construction site. However, in many cases, the dimensions do not match at the end of the connection row of the outer wall material at the edge of the building, around the window, around the entrance, etc., so the standard size outer wall material cannot be used as it is. For this reason, in such a place, the outer wall material of a standard size is cut and used so as to have a required size at the site. In this case, since the female real part or the male real part does not exist at the end of the outer wall material, the mounting bracket having the engaging part engaged with each real part as described above cannot be used. Conventionally, a nail hole is made in the thickness direction of the outer wall material, and the outer wall material is directly nail-fixed.

  For this reason, in this part, the same problem as the case where the above-mentioned outer wall material is directly attached to the housing side material with a nail has occurred.

  In addition, in order to eliminate the drawbacks of direct nail fastening, a mounting bracket that does not have an engaging portion that is engaged with the outer wall material is previously fastened to the back side of the outer wall material with a screw in advance. A method of attaching the cut outer wall material to the building by setting the outer wall material at the mounting position and then screwing the mounting bracket to the housing side material was also performed (in this case, the outer wall material was previously attached to the outer wall material). The reason for attaching the mounting bracket is that, in general, there is not enough space at the end of the connection row of the outer wall material to allow the mounting bracket to be attached later.

  However, in such a construction method, it takes time and effort to accurately position the mounting bracket (necessary number of mounting brackets to be attached to one outer wall material) with respect to the outer wall material, and the mounting bracket is screwed on the outer wall material. There was a problem that it took time and effort to fasten. In addition, there is a problem that the surface layer of the outer wall material may be damaged by the tip of the screw screwed from the back side of the outer wall material (the outer wall material generally has a design unevenness, so there is a thin portion. , Prone to such problems).

  Conventionally, for the same reason, there has been a problem that workability is poor in attaching an L-shaped outer wall material (outer corner material, incoming corner material) attached to a corner portion of a building.

  Therefore, the applicant previously proposed in Japanese Patent Application No. 2006-356941 the following outer wall material mounting bracket and outer wall material mounting method capable of solving the problems of the prior art.

  The present embodiment relates to a case where the standard size outer wall material 1 is cut and attached to the building at the end portion of the connection row of the flat outer wall material 1 at the edge of the building, around the window, around the entrance, etc. . FIG. 1 shows a standard-sized flat plate-like outer wall material 1 according to the present embodiment, in which one outer wall material 1 is provided with a male real part 2 at one end and a female real part 3 at the other end. . The male real part 2 and the female real part 3 are provided with inclined surfaces 2a and 3a which are inclined with respect to the entire outer wall material 1, respectively. In addition, as the outer wall material 1 in the present invention, wood, ceramics, metal, and other various materials can be used.

  FIG. 2 shows an attached state of the outer wall material 1 at a location where the standard size outer wall material 1 can be used as it is. The standard mounting bracket 4 has a male and female engaging portion 5 that engages with the male and female portion 2 of the outer wall material 1 and a female and female engaging portion 6 that engages with the female real portion 3. The male and female engaging portions 5 and 6 are respectively provided with forward movement blocking portions 7 and 8 that are inclined corresponding to the inclined surfaces 2 a and 3 a of the outer wall material 1. The standard mounting bracket 4 has a screw 10 attached to a building frame side material (base material, frame itself, etc.) 9 in a state in which the male engaging part 5 is engaged with the male part 2 of the outer wall material 1 to be attached first. Or attached by nails. The female real part 3 of the outer wall material 1 to be attached next is engaged with the female real engagement part 6 of the standard mounting bracket 4. In this way, the outer wall material 1 is successively attached to the housing side material 9 via the standard mounting bracket 4 in a phased manner in a state where the standard mounting bracket 4 is interposed between the butted portions of the outer wall materials 1. Go.

  However, in many cases, the dimensions do not match at the end of the connection row of the outer wall material 1 at the edge of the building, around the window, around the entrance, etc., so the standard size outer wall material 1 cannot be used as it is. In such a place, as shown in FIG. 3, the outer wall material 1 of a standard size is cut so as to have a required size at the site (the one-dot chain line in FIG. 3 is the one of the outer wall material 1 cut off) Shows the part). At this time, the cut surface of the outer wall material 1 forms an end surface 1 c perpendicular to the entire outer wall material 1. And as FIG. 4 shows, the attachment groove | channel 11 extended in the length direction of this end surface 1c is formed in the cut end surface 1c. At this time, the side wall 11a on the outer wall material rear surface 1a side of the mounting groove 11 forms an inclined surface inclined with respect to the entire outer wall material 1, and the side wall 11b on the outer wall material front surface 1b side is non-inclined parallel to the entire outer wall material 1. Make a face.

  5-7 has shown the groove cutting rotary cutter (diamond cutter) 31 for outer wall materials for forming the said attachment groove | channel 11 in a present Example. A central hole 33 for mounting on a driving device (not shown) is provided at the center of a circular substrate 32 made of carbon tool steel or the like. As well shown in FIG. 7, a diamond abrasive layer 34 is fixed to the outer peripheral portion of the substrate 32 by electrodeposition or the like, and a blade portion 35 is constituted by a portion to which the diamond abrasive layer 34 is fixed. ing. The radial cross-sectional shape of the blade portion 35 corresponds to the cross-sectional shape of the mounting groove 16 to be formed, and one side of the radial cross-sectional shape of the blade portion 35 is relative to the rotation axis of the rotary blade 31. An inclined side 35a inclined with respect to a vertical plane is formed, and the other side is formed with a non-inclined side 35b parallel to the plane perpendicular to the rotation axis of the rotary blade 31 (this is paraphrased as a superordinate concept). For example, the rotational trajectory cross-sectional shape obtained by sectioning the rotational trajectory of the blade portion 35 in the radial direction corresponds to the transverse cross-sectional shape of the mounting groove 16 to be formed, and one side of the cross-sectional shape of the rotational trajectory is The inclined side is inclined with respect to a plane perpendicular to the rotation axis of the rotary blade 31, and the other side is a non-inclined side parallel to the plane perpendicular to the rotary axis of the rotary blade 31) .

  FIGS. 8 and 9 show an operation of creating the attachment groove 16 in the outer wall material 1 by the rotary blade 31. As shown in these drawings, the rotary blade 31 is cut into the outer wall material 1 by a predetermined depth in the end surface 1c of the outer wall material 1 while rotating the rotary blade 31 by the driving device. Accordingly, as shown in FIG. 10, the side wall 11 a on the outer wall material rear surface 1 a side of the mounting groove 11 forms an inclined surface that is inclined with respect to the entire outer wall material 1, and the side wall 11 b on the outer wall material front surface 1 b side extends over the entire outer wall material 1. On the other hand, it is possible to process the mounting groove 16 having a predetermined shape that forms a parallel non-inclined surface very easily.

  Here, after the rotary blade 31 is cut into the outer wall material 1 by a predetermined depth in the direction (the left direction in FIGS. 8 and 9) which is the depth direction of the mounting groove 16, the end surface 1c of the outer wall material 1 extends (see FIG. If the rotary blade 31 is slid in the direction perpendicular to the paper surface in FIG. 8 and the vertical direction in FIG. 9, the cross-sectional shape of the mounting groove 16 to be formed can be made the same size and shape regardless of the position. . However, if the rotary blade 31 is slid after being cut in the depth direction, the work efficiency is deteriorated.

  In the present embodiment, at the position where the outer wall material mounting bracket 12 is to be mounted, the rotary blade 31 is only cut into the outer wall material 1 by a predetermined depth in the direction of the depth direction of the mounting groove 16, and the end surface 1 c of the outer wall material 1. The rotary blade 31 is not slid in the extending direction. Thereby, work efficiency can be improved. However, in this case, the size and shape of the cross-sectional shape of the mounting groove 16 vary depending on the position of the end surface 1c in the length direction. 9 and 10 show the circumstances of this area. The cross-sectional shape of the mounting groove 11 in the AA cross section and the BB cross section in FIG. 9 is as shown in A and B in FIG. In this embodiment, the cutting position of the rotary blade 31 is determined so that the cutting of the rotary blade 31 is deepest at the center position of the mounting position of the outer wall material mounting bracket 12 (that is, the mounting of the outer wall material mounting bracket 12). The center position of the position and the line AA in FIG.

  FIGS. 11-13 has shown the other example of the rotary blade 31 (tip saw). A central hole 37 for mounting on a driving device (not shown) is provided at the center of a substantially circular substrate 36 made of carbon tool steel or the like. On the outer peripheral side of the substrate 36, an appropriate number of tooth portions 38 are provided at equal angular intervals. A diamond tip 39 made of PCD (polycrystalline diamond sintered body) is fixed to the vicinity of the tip corner of each tooth portion 38. In this embodiment, the tip 39 constitutes the blade portion 39.

  12 is a cross-sectional view taken along the line XII-XII in FIG. 13 near the blade portion 39, and FIG. 13 is a cross-sectional view of the rotation locus of the blade portion 39 when the rotary blade 31 is rotated about its axis in the radial direction. The rotational trajectory cross-sectional shape 40 is shown (the rotational trajectory cross-sectional shape 40 is substantially the same graphic as the blade 39 viewed from the direction of FIG. 14). In this way, one side 45a of the rotational locus cross-sectional shape 40 obtained by sectioning the rotational locus of the blade portion 39 in the radial direction has an inclined side 45a inclined with respect to a plane perpendicular to the rotational axis of the rotary blade 31. None, the other side 45 b forms a non-inclined side 45 b parallel to a plane perpendicular to the rotation axis of the rotary blade 31.

  The mounting groove 11 can be similarly processed by using the rotary cutter 31 shown in FIGS. 11 to 13 instead of the rotary cutter 31 shown in FIGS.

  Next, instead of the standard mounting bracket 4, the outer wall material mounting bracket 12 according to the present invention shown in FIGS. 14 to 23 is used for termination, and the cut outer wall material 1 is mounted. First, the outer wall material mounting bracket 12 will be described. The mounting bracket 12 is formed by pressing a single metal plate made of a steel plate, a stainless steel plate, an aluminum alloy plate, or the like, and has a base 13 and a pair of cut and raised pieces. 14 integrally. The base 13 is generally rectangular in shape as a whole, and the peripheral portion 13a of the base 13 is basically formed so as to exist on one plane, and is attached to the building frame side material 9 The flat surface of the housing side member 9 is brought into contact with the casing side member 9. Most of the base portion 13 except for the vicinity of the peripheral edge portion 13a is raised in a flat shape by press drawing for the purpose of increasing the strength and rigidity of the entire mounting bracket 12, and raised in this flat shape. The portion is an outer wall material back surface facing portion 13b. The outer wall material rear surface facing portion 13b forms a plane parallel to the peripheral edge portion 13a. Therefore, when the mounting bracket 12 is attached to the housing side member 9, the outer wall material back surface facing portion 13 b is positioned in the vertical plane, and between the outer wall material back surface facing portion 13 b and the housing side material 9. Will form a gap (see FIG. 27).

  The pair of cut and raised pieces 14 are provided at symmetrical positions in the base portion 13. Each of these cut-and-raised pieces 14 is cut and raised from the outer wall material rear surface facing portion 13b, and has a front projecting portion 14a and a forward movement blocking portion 14b. The front projecting portion 14a is bent at a right angle from the outer wall material rear surface facing portion 13b and protrudes forward (in a direction away from the building or the housing side material 9 in the horizontal direction). The forward movement blocking portion 14b is bent obliquely from the front overhanging portion 14a, and the gap between the outer wall material back surface facing portion 13b and the outer wall material back surface facing portion 13b becomes larger as the distance from the front overhanging portion 14a increases. Inclined obliquely in the direction. The inclination angle of the forward movement blocking portion 14 b corresponds to the inclination angle of the side wall 11 a of the mounting groove 11. The front end side and the outer corner 24 of each forward movement blocking portion 14b have a relatively large arc shape.

  A burring-processed screw hole 15 is provided on the symmetry axis (center line of the outer wall material mounting bracket 12) of the pair of cut and raised pieces 14 and in the vicinity of one end of the outer wall material rear surface facing portion 13b. Yes. The front end portion of the hole flange 15a of the screw hole 15 is located on the same plane as the back surface of the peripheral edge portion 13a of the base portion 13, and comes into contact with the surface of the housing side material 9 when attached to the housing side material 9. It has become so.

  A pair of curved slit-like holes 25 are provided between the pair of front movement blocking portions 14b and in the vicinity of each front movement blocking portion 14b of the plate material constituting the outer wall material back surface facing portion 13b. Of the plate material constituting the outer wall material mounting bracket 12, the portion surrounded by each hole 25 constitutes a deformable piece 26. These deformable pieces 26 are partially surrounded by the holes 25, respectively, so that only a part of the deformable pieces 26 is continuous with the outer wall material back surface facing portion 13b and the other portions are discontinuous with respect to the outer wall material back surface facing portion 13b. Thus, it can be bent and deformed so that it can be displaced in the front-rear direction with respect to the outer wall material rear surface facing portion 13b. Each deformable piece 26 is provided with a dot-like fixing protrusion 16 protruding forward.

  Here, the outer wall material rear surface facing portion 13b, the forward projecting portion 14a, the forward movement blocking portion 14b, the deformable piece 26 and the fixing projection 16 constitute an outer wall material engaging portion 17, and this outer wall material engagement The outer wall material back surface facing portion 13b, the forward projecting portion 14a, and the forward movement blocking portion 14b of the joint portion 17 are generally hook-shaped when viewed in cross section.

  A rib-like elongated deformation projecting rearward (in the direction approaching the building or the housing side material 9 in the horizontal direction) around the screw hole 15 and in the vicinity of the fixing projection 16 in the outer wall material rear surface facing portion 13b. A prevention protrusion 18 is provided. The deformation preventing protrusion 18 surrounds the screw hole 15 between the fixing protrusion 16 and the screw hole 15, and further extends to the vicinity of the center portion in the width direction of each front projecting portion 14a. The top of the deformation preventing projection 18 is located on the same plane as the back surface of the peripheral edge 13 a of the base 13, so that when it is attached to the housing side material 9, it comes into contact with the surface of the housing side material 9. It has become.

  Next, a method for mounting the outer wall material 1 using the mounting bracket 12 described above will be described. 24 and 25, in the state where the outer wall material back surface facing portion 13b of the mounting bracket 12 faces the back surface 1a of the outer wall material 1, from the mounting groove 11 in the end portion of the outer wall material 1 on the end surface 1c side. The mounting bracket 12 is moved relative to the outer wall material 1 so that the portion on the rear surface 1a side enters the outer wall material engaging portion 17, that is, between the outer wall material rear surface facing portion 13b and the forward movement blocking portion 14b. Then, as shown in FIG. 25, the inner surface of the forward movement blocking portion 14b comes into contact with the side wall 11a of the mounting groove 11, and the fixing projection 16 comes into contact with the back surface 1a of the outer wall material 1 as shown in FIG. The outer wall material engaging portion 17 of the mounting bracket 12 is engaged. In FIG. 26, the deformable piece 26 is at the position indicated by the alternate long and short dash line in the initial state, and protrudes relatively large from the surface of the outer wall material rear surface facing portion 13b. Is brought into contact with the back surface 1a of the outer wall material 1 to be pushed rearward and bend and deform backward. Since the contact area between the fixing protrusion 16 and the back surface of the outer wall material 1 is small, the fixing protrusion 16 is pressed against the back surface of the outer wall material 1 with a relatively large pressure. When the outer wall material engaging portion 17 is engaged with the outer wall material 1, the outer wall material mounting bracket 12 is fixed to the outer wall material 1 (note that the fixing strength of the mounting metal 12 to the outer wall material 1 is The mounting bracket 12 only needs to be large enough to prevent the mounting bracket 12 from dropping or slipping from the outer wall member 1 until the mounting work of the mounting bracket 12 to the housing side member 9 described later is completed. ).

  Accordingly, as described above, only the mounting bracket 12 is moved relative to the outer wall material 1 such that the portion of the end portion of the outer wall material 1 on the back surface 1a side from the mounting groove 11 is inserted into the outer wall material engaging portion 17. Thus, the mounting bracket 12 can be fixed to the outer wall material 1 very simply and quickly without screwing.

  When the outer wall member engaging portion 17 is engaged with the end portion of the outer wall member 1, the position of the mounting bracket 12 with respect to the outer wall member 1 in the direction perpendicular to the end portion is naturally determined. The mounting bracket 12 can be positioned very easily in any direction.

  Further, the fixing strength of the mounting bracket 12 with respect to the outer wall material 1 is such that the mounting bracket 12 falls off or deviates from the outer wall material 1 until the mounting work of the mounting bracket 12 with respect to the housing side material 9 described later is completed. The size of the outer wall material 1 can be set to a size that is large enough to prevent the fixing and the fixing position of the mounting bracket 12 with respect to the longitudinal direction of the outer wall material. Positioning of the mounting bracket 12 with respect to the direction can be easily performed.

  In general, not only one mounting bracket 12 but a required number of mounting brackets 12 are attached to the outer wall material 1 as described above. Next, the mounting member 12 fixed to the outer wall member 1 as described above is attached to the housing side member 9 with screws 19 using screw holes 15 as shown in FIG. It can be attached to the building via

  Therefore, it is possible to attach the outer wall material 1 to the building using the mounting bracket 12 instead of directly nailing at the terminal portion of the connection row of the outer wall material 1. Moreover, in attaching the outer wall material 1 to the building at the end of the connection row of the outer wall material 1, the mounting bracket 12 can be easily and quickly fixed to the outer wall material 1 and the mounting bracket 12 is positioned with respect to the outer wall material 1. Since it can be performed very easily as described above, the workability of the mounting work can be greatly improved.

  Further, as described in the section “Problems to be Solved by the Invention”, in the embodiment of the outer wall material mounting bracket and the outer wall material mounting method previously proposed by the present applicant in Japanese Patent Application No. 2006-356941, the outer wall Depending on the material, excessive stress concentration occurs in the contact portion between the fixing projection 16 of the outer wall material mounting bracket 12 and the outer wall material 1, and the outer wall material 1 is cracked from the contact portion and the outer wall material 1 is damaged. There was a problem that sometimes.

  However, in the outer wall member mounting bracket and the outer wall member mounting method of the present invention, the fixing protrusion 16 abuts against the back surface 1a of the outer wall member 1 while the deformable piece 26 is deformed rearward. It is possible to prevent an excessive stress concentration from occurring at the contact portion between the 12 fixing protrusions 16 and the outer wall material 1, and cracking of the outer wall material 1 from the contact portion to break the outer wall material 1. When the outer wall material engaging portion 17 of the mounting bracket 12 is engaged with the outer wall material 1, the contact portion between the fixing projection 16 and the outer wall material 1 is substantially flush with the surface of the outer wall material rear surface facing portion 13b. Thus, it is preferable that the deformable piece 26 is deformed.

  Further, as described in the section “Problems to be Solved by the Invention”, the front movement blocking portion 14b of the wall member mounting bracket 12 is formed in a rectangular shape as a whole, and the front side and the outside of the front movement blocking portion 14b. When the corner is a substantially right angle corner, when the mounting groove 11 is processed in the outer wall material 1, the rotary blade 31 is formed in the outer wall material 1 with a predetermined depth in the direction of the depth direction of the mounting groove 16. When only the cutting is performed and the rotary blade 31 is not slid in the direction in which the end surface 1c of the outer wall material 1 extends, the front end side and the outer corner of the forward movement blocking portion 14b are the side walls 11a of the mounting grooves 11 of the outer wall material 1. There was a problem of hitting locally. However, in the present embodiment, the front end side and the outer corner portion 24 of each forward movement blocking portion 14b are formed in a relatively large arc shape, and therefore the front end side and the outer corner portion 24 of the mounting groove 11 of the outer wall material 1 are formed. The side wall 11a is not strongly hit locally. Note that the “arc shape” as used herein for the shape of the front end side and the outer corner portion 24 of the forward movement blocking portion 14b is not limited to a geometrically pure arc shape, but is a curved shape close to it. Also good.

  In addition, since a gap is formed between the outer wall material back surface facing portion 13b and the housing side material 9, when the deformation preventing projection 18 is not present, the mounting bracket 12 is tightened by tightening the screw 19 or other factors. The outer wall material 1 is deformed until the outer wall material rear surface facing portion 13b is deformed and the fixing projection 16 is not strongly pressed against the rear surface 1a of the outer wall material 1 by a sufficiently large force, and screwing to the housing side material 9 is completed. On the other hand, there is a possibility that the mounting bracket 12 cannot be fixed with sufficient strength, or even after the screwing is completed, the fixing protrusion 16 does not contact the outer wall material 1 reliably, and the mounting state of the outer wall material 1 may be loose. . However, in the present embodiment, the deformation is projected rearward in the vicinity of the fixing projection 16 and the deformation preventing projection 18 that contacts the housing side material 9 is provided. Therefore, the deformation of the outer wall material rear surface facing portion 13b is provided. The fixing projection 16 can be always pressed against the back surface 1a of the outer wall material 1 with a sufficiently large force. As a result, until the screwing is completed, the state in which the mounting bracket 12 is fixed to the outer wall material 1 with sufficient strength is maintained, and the fixing protrusion 16 firmly contacts the outer wall material 1 even after screwing. It is possible to prevent the play from occurring in the attached state of the outer wall material 1.

  Further, in this embodiment, the tip end portion of the hole flange 15a of the screw hole 15 is also in contact with the housing side member 9, so that this also further prevents the deformation of the outer wall material back surface facing portion 13b, The mounting bracket 12 can be fixed to the material 1 with sufficient strength.

  Further, in the present invention, the entire cross section of the end portion of the outer wall material may be inserted into the outer wall material engaging portion of the mounting bracket without necessarily providing the mounting groove on the end surface of the outer wall material. However, if the mounting groove 11 is provided on the end face of the outer wall material 1 as in the present embodiment, the outer wall material engaging portion 17 can be prevented from being exposed to the outside, and the outer wall material 1 can be connected via the mounting bracket 12. Can be securely attached to the building.

  Furthermore, in this embodiment, the forward movement blocking portion 14b of the mounting bracket 12 is located between the forward movement blocking portion 14b and the outer wall material rear surface facing portion 13b as it goes from the entrance side of the outer wall material engaging portion 17 to the back side. Since it is inclined obliquely with respect to the outer wall material back surface facing portion 13b in the direction of decreasing the gap, and the side wall 11a on the outer wall material back surface 1a side of the mounting groove 11 of the outer wall material 1 is also inclined correspondingly, Since the portion of the outer wall material 1 on the back surface 1a side from the mounting groove 11 can be wedged into the outer wall material engaging portion 17 of the mounting bracket 12, the shape / dimensional accuracy of the mounting bracket 12 and the mounting groove The outer wall material 1 can be securely, firmly and easily attached without making the processing accuracy of the eleventh high, and the base side of the portion on the back surface 1a side is thicker than the attachment groove 11 of the outer wall material 1. What can be done More, it is possible to increase the strength of the outer wall member first end. However, in the present invention, the forward movement blocking portion of the mounting bracket and the side wall of the mounting groove of the outer wall material that abuts on the portion may not necessarily be inclined.

  In addition, in the construction method of the flat outer wall material, the vertical stretching method in which the longitudinal direction of the outer wall material is attached to the housing side as the vertical direction, and the horizontal direction in which the longitudinal direction of the outer wall material 1 is attached to the housing side as the horizontal direction. Although there is a tension method, the present invention is applicable to both vertical and horizontal methods.

Further, in this embodiment, the female real part 3 of the outer wall material 1 to be attached next is abutted against the male real part 2 of the outer wall material 1 to be attached first, but the present invention is attached first. The present invention can also be applied to the case where the male real part 2 of the outer wall material 1 to be attached next to the female real part 3 of the outer wall material 1 is abutted.

  FIG. 28 shows a second embodiment of the present invention. In the present embodiment, the outer wall material 21 is an outer wall protruding corner member having an L-shaped cross section used for a protruding corner portion of a building. On both end faces 21c of the outer wall member 21, mounting grooves 22 having the same shape as the mounting groove 11 of the first embodiment are provided. That is, the side wall 22 a on the outer wall material rear surface 21 a side of each mounting groove 22 forms an inclined surface inclined with respect to the entire outer wall material 21, and the side wall 22 b on the outer wall material front surface 21 b side is non-inclined parallel to the entire outer wall material 21. It has a surface. The mounting groove 22 may be provided in advance in the outer wall material 21 during the manufacturing process in the factory, or may be processed on site.

  The mounting bracket 12 is the same as that in the first embodiment. Also in the present embodiment, as in the case of the first embodiment, first, the outer wall material engaging portion 17 is engaged with the portion on the back surface 21a side from the mounting groove 22 in the both end portions of the outer wall material 21, and the mounting bracket is attached. After fixing 12 to an appropriate place on the outer wall member 21, the outer wall member 21 can be attached to the building by attaching the mounting bracket 12 to the housing side member 23 with the screw 19.

  Also in this embodiment, the fixing protrusion 16 abuts against the back surface 21a of the outer wall member 21 while the deformable piece 26 is deformed rearward, so that the fixing protrusion 16 and the outer wall member 21 of the outer wall member mounting bracket 12 are contacted. It is possible to prevent excessive stress concentration from occurring at the contact portion with the outer wall material 21 from being cracked from the contact portion and damaging the outer wall material 21.

Further, when the mounting groove 22 is processed in the outer wall material 21, the rotary blade 31 is only cut into the outer wall material 22 by a predetermined depth in the direction of the depth direction of the mounting groove 16, and the end surface 21c of the outer wall material 21 extends. When the rotary blade 31 is not slid in the direction, the front end side and the outer corner portion 24 of each forward movement blocking portion 14b have a relatively large arc shape. It does not hit the side wall 21a of the mounting groove 21 of the outer wall material 23 locally and strongly.

In the first and second embodiments, the end surfaces 1c and 21c of the outer wall materials 1 and 21 form a plane perpendicular to the entire outer wall materials 1 and 21, but in the present invention, the end surfaces of the outer wall materials are It may be an inclined surface or may not be a flat surface (for example, it may be composed of a plurality of surfaces bent with respect to each other).

  In addition, the first embodiment is an example in which the present invention is applied to the case where the outer wall material 1 cut at the end of the connection row of the flat outer wall material 1 is attached, and the second embodiment is an outer wall having an L-shaped cross section at the protruding corner. Although it is an example applied when attaching material (protruding corner material), this invention is applicable also regarding attachment of the outer wall material in other cases. For example, the flat outer wall material 1 can be applied to an outer wall material mounting bracket and an outer wall material mounting method for mounting at a place other than the terminal end of the connection row. The operator does not need to screw or nail the mounting bracket to the housing side material while holding down both the outer wall material and the mounting bracket, so that the workability can be improved and the outer wall material due to the presence of the fixing protrusions. It is possible to obtain an effect such as prevention of damage. Normally, in this case, one mounting member is provided with outer wall material engaging portions that respectively engage with adjacent outer wall materials. The present invention can also be applied to the starting end portion of the connection row of flat outer wall materials. Furthermore, the present invention can be applied to attachment of a corner material or the like.

In each of the above embodiments, the mounting bracket 12 is mounted on the housing side member with the screw 19. However, depending on the case, a nail hole is provided instead of the screw hole 15, and the mounting bracket is used by using this nail hole. May be attached to the housing side material with nails. Also in this case, the deformation preventing protrusion prevents deformation of the mounting bracket due to nailing.
