Description

  The present invention relates to an attachment structure for attaching an exterior member to the surface of a plate-like panel provided in a building frame or the like, and the exterior member can be firmly attached to the panel without drilling or the like. This relates to the mounting structure.

  Extruded cement boards are widely used as building exterior materials because they are lightweight and have high strength. When attaching an exterior member such as a tile to the surface of a panel such as an extrusion-molded cement board, it is affixed directly with an adhesive or mortar. When it is directly attached with an adhesive or mortar, it is necessary to periodically inspect the tile and the like after the construction.

  For example, a hole that leads from the surface of the extruded cement board to the hollow part is opened, a receiving member is installed in the hollow part, a plate is installed on the front side of the extruded cement board, and the receiving member and the plate are fixed bolts through the hole. The attachment method which attaches an exterior member is known by tightening by. According to this method, since the exterior member is received by the fixing bolt through the hole, the mounting reliability is improved and the inspection can be reduced as compared with the case where the adhesive member or the mortar is directly attached.

  On the other hand, if a hole leading to the hollow part of the extruded cement board is made, it is assumed that fracture will occur with a force smaller than the original bending strength when subjected to negative pressure. It is necessary to do. Designing with a lower allowable stress level leads to a reduction in the support span of the extruded cement board, and there is a problem that the flexibility of the support span of the building is reduced. In addition, once a hole is made, even if it is repaired, such a problem occurs. Therefore, it is not possible to make a second hole for attaching another exterior member, and the degree of freedom of the exterior member to be used is reduced. .

  As an attachment structure that does not open a hole in an extruded cement board, for example, an attachment structure described in Patent Document 1 is known. In Patent Document 1, a fixing portion that is attached between the bottom surface of the groove portion of the panel and the engaging convex portion provided on the rib and is attached to the groove portion, and an auxiliary member for plant extension that is coupled to the fixing portion are attached. An auxiliary member fixture provided with a mounting portion for the purpose, and a greening structure using the same are described. In this auxiliary member mounting tool, the pressing member provided on the bottom surface side of the fixing portion engages and presses the fixing portion with the engaging convex portion, thereby fixing the auxiliary member mounting tool.

  Patent Document 2 describes a mounting structure for a heat insulating panel in contact with a concrete wall surface. In this structure, a trapezoidal groove having a trapezoidal cross section is formed in the heat insulating panel, and a fixing metal is engaged with the groove, thereby fixing the heat insulating panel. The fixture has a plate in contact with the panel surface and a bent metal fitting in a dovetail groove, and a hooking space constituted by the plate and the bent metal fitting in contact with the plate is formed at the edge of the groove. The insulation panel is attached by hooking.

JP2013-094091A Japanese Utility Model Publication No. 57-204351

  In the mounting structure described in Patent Document 1, the pressing portion provided on the bottom surface side of the fixing portion is pressed by engaging the fixing portion with the engaging protrusion. An excessive pressing force may be applied to the part. If an excessive pressing force is applied to the engaging convex portion, the engaging convex portion may be deformed or damaged, and the size of the pressing force is limited. Since the holding force of the fixing portion is also restricted by restricting the magnitude of the pressing force, the exterior member attached to the surface is limited.

  In the mounting structure described in Patent Document 2, there is a possibility that rattling may occur between the hooking space and the edge of the groove depending on the size of the hooking space constituted by the plate and the bent metal and the accuracy of the edge of the groove. There is. Moreover, the force which acts on the edge part of a groove | channel becomes any one direction of a front-back direction. When such an attachment structure is applied to a panel such as an extrusion-molded cement board, as in the case of Patent Document 1, there is a risk that the edge portion of the groove may be deformed or damaged, and the exterior members attached to the surface are limited. There is a problem.

  Therefore, in view of the problems of the prior art, the present invention has an object to provide an exterior member mounting structure and an outer wall structure in which the allowable stress level due to drilling is not reduced, and the exterior member to be attached and the attachment position are not limited. And

  The mounting structure of the exterior member of the present invention is a mounting groove extending in one direction formed on the surface portion of the panel in the mounting structure of the exterior member to the plate-like panel, and is provided on both sides in the groove width direction. A mounting groove in which a long eaves portion that protrudes from each other and extends along the groove opening edge is formed on the groove opening edge, and a presser that is in contact with the front side of the long elongate part outside the mounting groove A member, a fixing member that is in contact with the back side of the long elongate part inside the mounting groove, and the pressing member that is in contact with each of the front and back sides of the both long eaves part and the fixing member A fastening member for fixing the exterior member, and both the long flange portions are sandwiched between the pressing member and the fixing member from both sides in the front and back directions with substantially the same pressing force. Is.

  According to the mounting structure of the exterior member of the present invention, the long opening portions that face each other in a projecting manner and extend along the groove opening edge are formed on the groove opening edges on both sides in the groove width direction of the mounting groove. By tightening the holding member that is in contact with each of the front and back of the buttock and the fixing member, both the long ridges are sandwiched with the same pressing force from both sides in the front and back direction. A force in one direction by the pressing member or the fixing member does not act, and both the long hook portions are only pressed down from the front and back sides. Therefore, there is no possibility that the long elongate portion will be deformed or damaged by tightening the pressing member and the fixing member. Thereby, since only the load which hold | maintains an exterior member is applied to both long collar parts, various exterior members can be attached and an attachment position is not restrict | limited. Further, it is not necessary to make a hole in the panel, and the allowable stress level does not decrease due to the opening.

  The fixing member is formed with a screw hole penetrating the front and back, and the fastening member is threadably engaged with the screw hole of the fixing member so that the fixing member can advance and retreat with respect to the groove bottom of the mounting groove. What is necessary is just to space apart a bottom and the front-end | tip of the said fastening member. The groove bottom of the mounting groove and the tip of the fastening member that can be moved forward and backward are separated from each other, and the groove bottom of the mounting groove is tightly connected even after the fastening member is screwed into the screw hole of the fixing member. It is not in a state of being pushed by a member. If the bottom of the mounting groove is pressed with the binding member, the reaction force from the bottom of the mounting groove will break the balance of the pressing force sandwiched from the front and back of both long flanges. There is no waking.

  Each of the long elongate portions has an inclined back surface that is inclined so that the distance between the long elongate portions becomes narrower toward the front side, and the fixing member extends to both sides of the base portion and the base portion. And an inclined portion along the inclined back surface of the flange portion, and each of the inclined portions of the fixing member may be in contact with the inclined back surface of each of the long flange portions. Each of the inclined portions of the fixing member is brought into contact with the inclined back surface of each elongate portion, so that the pressing force to the back side of each elongate portion becomes an oblique direction, and the pressing force is thicker than each elongate portion. Can be directed to thick parts. Therefore, the proof stress of each eaves part improves, attachment strength can be raised, and an exterior member can be attached firmly.

  The pressing member may have any shape and size. For example, the pressing member may be configured as a part of the exterior member. In this case, the constituent members of the mounting structure of the exterior member can be reduced.

  What is necessary is just to make the said panel into the extrusion-molded cement board in which the several hollow part was arranged in parallel by one direction, for example. In this case, various exterior members can be attached to the outer wall composed of the extruded cement board.

  In the outer wall structure of the present invention, a wall surface of a building is constituted by a plurality of the panels in which a plurality of the mounting grooves are arranged side by side, and the entire surface or a part of the wall surface is formed by any one of the exterior member mounting structures described above. The exterior member is attached.

  According to the outer wall structure of the present invention, an outer wall structure to which various exterior members can be attached can be obtained by an attachment structure that does not cause a reduction in the allowable stress level of the panel. Moreover, an exterior member can be attached to the whole surface or a part of surface of this design panel, providing the function as a design panel with a rib by which the rib was comprised between adjacent attachment grooves.

  According to the present invention, the unidirectional force by the pressing member or the fixing member does not act on both the long hook portions, and only the both long hook portions are pressed evenly from the front and back. There is no risk of deformation or breakage of the long eaves. Thereby, since only the load which hold | maintains an exterior member is applied to both long collar parts, various exterior members can be attached and an attachment position is not restrict | limited. Further, it is not necessary to make a hole in the panel, and the allowable stress level does not decrease due to the opening.

It is a cross-sectional view of the principal part of the attachment structure of the exterior member of FIG. It is a perspective view of an insertion nut (fixing member). It is a cross-sectional view which shows the attachment structure of the exterior member which concerns on 3rd Embodiment of this invention. It is a state figure showing the state where the exterior member was attached. It is a cross-sectional view showing an example in which another exterior member is attached.

  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view showing an exterior member mounting structure 1 according to the first embodiment of the present invention, and FIG. 2 is a cross-sectional view of a main part of the exterior member attachment structure 1 of FIG. In the present embodiment, an example in which the extruded cement board 2 is used as a panel to which the exterior member 100 is attached will be described. The extruded cement board 2 attached to the building frame by the horizontal or vertical construction method is a mixture of cement, aggregates, fibers, blends, etc. kneaded, extruded with an extruder, cured and cured to a predetermined size. It was produced. In the following description, the extrusion direction of the extrusion-molded cement board 2 is defined as the longitudinal direction (through direction in FIG. 1), and the direction orthogonal to the extrusion direction (left-right direction in FIG. 1) is defined as the width direction.

  A plurality of hollow portions 3 having a rectangular cross section are formed in the extruded cement plate 2 in parallel with each other in the longitudinal direction. The extrusion-molded cement board 2 includes a surface side base material (surface portion) 4 constituting a front side portion, a back side base material 5 constituting a back side portion, and a plurality of partition walls 6 connecting the surface side base material 4 and the back side base material 5. , And a fitting portion 7 for fitting with another adjacent extruded cement board.

  The surface side base material 4 is formed thicker than the back side base material 5, and a plurality of mounting grooves 10 extending in the longitudinal direction are formed in the surface side base material 4. In the present embodiment, six mounting grooves 10 are formed, but the number of mounting grooves 10 and the position in the width direction are not limited. As shown in FIG. 2, long eaves portions 11 are formed on the groove opening edges 10a on both sides in the width direction (groove width direction) of the mounting groove 10 so as to face each other in a projecting manner and extend in the longitudinal direction along the groove opening edge 10a. Has been. These long flange portions 11 protrude in the width direction. The elongate part 11 is formed in a cross-sectional substantially rectangular shape across the both ends of the longitudinal direction of the extrusion-molded cement board 2. Due to the presence of the long flange portions 11 on both sides, the groove opening edge 10a of the mounting groove 10 is narrowed. The mounting groove 10 has a narrow space 12 between the long flange portions 11 and a wide space inside the narrow space 12. 13 and T-shaped.

  As shown in FIG. 1, a metal panel 102 provided with sound absorbing glass wool 101 is attached as an exterior member 100 to the surface of the extrusion-molded cement board 2 of the present embodiment. The metal panel 102 includes a base member 102a fixed to the surface of the extrusion-molded cement board 2 and cover members 102b fitted to the base member 102a and screwed on both sides thereof. After fixing the base member 102a to the extruded cement plate 2, the glass wool 101 is filled in the base member 102a, the glass wool 101 is covered with the cover member 102b, and the cover member 102b is fixed to the base member 102a.

  An insertion nut 14 (fixing member) is installed inside the mounting groove 10 of the extruded cement plate 2. The insertion nut 14 is inserted from the end of the mounting groove 10 of the extruded cement board 2. FIG. 3 is a perspective view of the insertion nut 14. The insertion nut 14 is formed in a rectangular flat plate shape, and a screw hole 14 a penetrating the front and back is formed at the center of the insertion nut 14. The insertion nut 14 has a width dimension larger than the narrow space 12 between the long flange portions 11, enters the back side of the long flange portion 11 in the wide space 13, and enters the long flange portion 11 from the inside of the mounting groove 10. It is in contact with the back surface 11a. The front-back direction dimension of the wide space 13 of the mounting groove 10 is larger than the thickness of the insertion nut 14. Therefore, a space is provided between the insertion nut 14 and the groove bottom 10s.

  A part of the base member 102 a of the metal panel 102 functions as the pressing member 15 in the exterior member mounting structure 1. By causing a part of the exterior member 100 to function as the pressing member 15, the constituent members of the exterior member mounting structure 1 can be reduced. The base member 102 a is in contact with the surface 2 a of the extruded cement plate 2, and is in contact with the surfaces 11 b of the long elongate portions 11 outside the mounting groove 10. A through hole 15a is formed in the pressing member 15 which is a part of the base member 102a of the metal panel 102, and a bolt (tightening member) 16 passes through the through hole 15a.

  As shown in FIG. 2, the bolt 16 is further screwed into the screw hole 14 a of the insertion nut 14 so as to be able to pass therethrough, and can advance and retreat with respect to the groove bottom 10 s of the mounting groove 10. The rectangular flat insertion nut 14 is restricted from rotating inside the mounting groove 10. By rotating the bolt 16, the holding member 15 and the insertion nut 14 that are brought into contact with the front and back of the both long hook portions 11 are fastened to each other, and the both long hook portions 11 are connected to the holding member 15 and the insertion nut 14. It is sandwiched from both sides in the front and back direction. The tip 16a of the bolt 16 that can be screwed into the screw hole 14a of the insertion nut 14 is separated from the groove bottom 10s of the mounting groove 10.

  In the state of FIG. 2 in which the bolt 16 is tightened and the pressing member 15 and the insertion nut 14 are tightly coupled, the tip 16 a of the bolt 16 is separated from the groove bottom 10 s of the mounting groove 10. Even after the bolt 16 has been screwed into the screw hole 14 a of the insertion nut 14, the groove bottom 10 s of the mounting groove 10 is not pushed by the bolt 16. Therefore, no reaction force from the groove bottom 10s acts on the insertion nut 14. If the tip 16a of the bolt 16 is in a state of pressing the groove bottom 10s of the mounting groove 10, a reaction force from the groove bottom 10s acts on the insertion nut 14, and the long flange portion 11 is moved with a large force from the back side. The insertion nut 14 is pressed.

  On the other hand, the reaction force from the groove bottom 10s does not act on the insertion nut 14 of the present embodiment, and the long flange portion 11 of the mounting groove 10 is sandwiched between the front and back with substantially the same pressing force f. Yes. If the bottom 16s of the mounting groove 10 is pushed by the bolt 16, the reaction force from the bottom 10s of the mounting groove 10 breaks the balance of the pressing force sandwiched from the front and back of the long flange portion 11. In the embodiment, this balance is not lost. By sandwiching the long elongate portions 11 from the front and back with substantially the same pressing force f, an excessive force is not applied to both the long eaves portions 11, and the mounting strength of the exterior member 100 is significantly improved.

  According to the exterior member mounting structure 1 of the present embodiment, the grooved edges 10a on both sides in the width direction of the mounting groove 10 face each other in a projecting manner and extend in the longitudinal direction along the grooved opening edge 10a. By forming the portion 11 and fastening the holding member 15 and the insertion nut 14 that are in contact with the front and back sides of the both long flange portions 11, both the long flange portions 11 have substantially the same pressing force f from both sides in the front and back direction. It is sandwiched between. Therefore, a force in one direction by the pressing member 15 or the insertion nut 14 does not act on the long elongate portions 11, and only the long elongate portions 11 are pressed evenly from the front and back. Therefore, there is no possibility that the long elongate portion 11 is deformed or damaged by tightening the pressing member 15 and the insertion nut 14. Thereby, since only the load which hold | maintains the exterior member 100 is applied to both the long collar parts 11, various exterior members 100 can be attached and an attachment position is not restrict | limited. In addition, it is not necessary to perforate the extrusion-molded cement board 2 and the permissible stress is not reduced by the perforation.

  Since the pressing member 15 and the insertion nut 14 are tightly coupled with the long flange portion 11 being sandwiched, these members can be easily replaced. Furthermore, since the insertion nut 14 can be slid in the longitudinal direction in the mounting groove 10 and the exterior member mounting structure 1 can be configured at any position of the mounting groove 10, the degree of freedom for mounting the exterior member 100 is improved. To do. Since the gap between the holding member 15 and the insertion nut 14 that sandwiches the long flange portion 11 from both sides of the front and back is provided, the tightness of the exterior member 100, the insertion nut 14, the pressing member 15, and the bolt 16 is increased. Regardless, the exterior member 100 can be attached more firmly.

  Further, the wall surface of the building is composed of a plurality of extrusion-molded cement plates in which a plurality of mounting grooves 10 are arranged in parallel, and the exterior member is attached to the entire surface or a part of the wall surface by the exterior member mounting structure 1 of the present embodiment. You may make it attach.

  In this case, an outer wall structure to which various exterior members can be attached can be obtained by an attachment structure that does not cause a reduction in the allowable stress level of the panel. Various exterior members can be attached to the entire surface or a part of the surface of the design panel while providing a function as a design panel with ribs in which ribs are formed between adjacent mounting grooves 10. Thereby, it can be set as the outer wall which has high designability and can attach various members to the surface.

  The shape of the mounting groove 10 and the shape of the insertion nut 14 are not limited as long as the long flange portion 11 can be sandwiched between the front and back surfaces with substantially the same pressing force. 4 is a transverse sectional view showing an exterior member mounting structure 20 according to the second embodiment of the present invention, and FIG. 5 is a transverse sectional view of a main part of the exterior member attachment structure 20 of FIG. FIG. 6 is a perspective view of the insertion nut 21 (fixing member).

  The present embodiment is different from the first embodiment in that the wide space 23 of the mounting groove 22 is formed in a substantially trapezoidal cross section, and the insertion nut 21 has a shape corresponding thereto. The configuration other than the mounting groove 22 and the insertion nut 21 and the mounting form of the metal panel are the same as in the first embodiment. The eaves portion 24 has an inclined back surface 24r that is inclined so that the distance between the elongate portions 24 decreases toward the front side, and is formed in a substantially triangular cross section.

  As shown in FIG. 6, the insertion nut 21 has a flat plate-like base portion 21 </ b> A, and inclined portions 21 </ b> B extending along both sides in the width direction of the base portion 21 </ b> A and extending along the inclined back surface 24 r of the long flange portions 24. As shown in FIG. 5, each of the inclined portions 21 </ b> B of the insertion nut 21 is in contact with the inclined back surface 24 r of each long flange portion 24. Since the holding members 27 and the insertion nuts 21 that are in contact with the front and back sides of the long elongate portions 24 are fastened by bolts 28, the long elongate portions 24 can be applied with substantially the same pressing force from both sides in the front and back directions. It is sandwiched. The tip 28 a of the bolt 28 that can be threaded into the screw hole 21 c of the insertion nut 21 is separated from the groove bottom 22 s of the mounting groove 22.

  In the present embodiment, when negative pressure is applied to the extruded cement board 25, the pressing force applied to the long flange portion 24 by the insertion nut 21 acts not only in the front and back direction but also in the direction of the arrow in FIG. . The oblique pressing force fa is applied in the vertical direction to the abutting long flange portion 24. Thereby, the shearing interface can be widened, and the attachment strength can be further improved.

  Each of the inclined portions 21b of the insertion nut 21 is brought into contact with the inclined back surface 24r of each elongated flange portion 24, so that the pressing force to the back side of each elongated flange portion 24 spreads in an oblique direction. It can be directed to the thicker thick portion 26 of each elongate portion 24. Therefore, the proof stress of each elongate part 24 can be improved, the attachment strength can be increased, and the exterior member 100 can be firmly attached.

  If the structure is such that the holding member 27 and the insertion nut 21 are in contact with each other, depending on the accuracy of these members, the elongate portion 24 may be insufficiently held, but a gap is provided between the two members. Regardless of the accuracy of these two members, the exterior member 100 can be more firmly attached.

  In the above embodiment, the pressing members 15 and 27 of the exterior member mounting structures 1 and 20 are configured as a part of the exterior member 100. However, the shape of the pressing member is to sandwich the long hook portion together with the insertion nut. As long as it is possible, it may be anything. FIG. 7 is a cross-sectional view showing an exterior member mounting structure 30 according to the third embodiment of the present invention, and FIG. 8 is a state diagram showing a state in which the exterior member 200 is attached in the configuration shown in FIG. The exterior member 200 of the present embodiment includes a glass wool 201 for sound absorption that is in direct contact with the extruded cement plate 31 and a cover member 202 thereof. Mounting grooves 32 extending in the longitudinal direction are formed only at both corners in the width direction of the extruded cement plate 31. The exterior member 200 is attached at two places on both corners in the width direction of the extruded cement board 31.

  The pressing member 33 is a plate material that is a rectangular shape in plan view that is separate from the exterior member 200. The shapes of the mounting groove 32 and the insertion nut 34 are the same as in the second embodiment. A cylindrical sleeve 35 having a thread on the inner surface is inserted into the glass wool 201. Bolts 36 are inserted into bolt holes provided in the cover member 202 and screwed into one end portion 35 a of the sleeve 35. All screw bolts 37 are screwed into the other end portion 35 b of the sleeve 35. By tightening the bolt 36, the pressing member 33 and the insertion nut 34 are tightly coupled. Since the holding member 33 and the insertion nut 34 that are in contact with the front and back surfaces of the both long flange portions 38 having a substantially triangular cross section are tightly coupled, the both long flange portions 38 have substantially the same pressing force from both sides in the front and back directions. It is sandwiched between.

  Similar to the second embodiment, when a negative pressure is applied to the extruded cement board 31, the pressing force applied to the long flange portion 38 by the insertion nut 34 is applied to the contacting long flange portion 38 in the vertical direction. . Thereby, the shearing interface can be widened, and the attachment strength can be further improved. In addition, the pressing force to the back side of each elongate portion 38 becomes an oblique direction, and this pressing force can be directed to the thicker thick portion 39 of each elongate portion 38. Therefore, the proof stress of each long eave part 38 can be improved, the attachment strength can be increased, and the exterior member 200 can be firmly attached.
