Description

  The present invention relates to a mounting structure for mounting an exterior member on a surface of an outer wall plate attached to a building frame of a building, and more particularly to an exterior member mounting structure capable of securely mounting an exterior member in various use environments. .

  For example, an extruded cement board is widely used as an outer wall board of a building because of its light weight and high strength. In an outer wall structure using an extruded cement board, an angle serving as a base material is generally fixed to the building frame, and a Z-clip or the like fastened to the back of the extruded cement board is locked to the angle, so that the extrusion is performed. A molded cement board is installed.

  Attachment members such as stones and tiles are also attached to the surface of an extruded cement board. Various types of exterior members are attached by directly attaching to the surface of the extruded cement plate with an adhesive or mortar, or by fastening to the extruded cement plate with a mounting bracket. Patent Literature 1 describes an outer wall structure in which concave portions and convex portions are alternately formed on an outer wall plate made of a ceramic material, and a decorative material is fixed to the exterior plate via a reinforcing material provided in the concave portion. Patent Literature 2 describes an outer wall structure in which a receiving bracket having a hook is fixed to an outer wall plate, and an exterior member is hooked and fixed to the hook of the receiving bracket.

  As in Patent Literature 3 and Patent Literature 4, there is also known an outer wall structure in which a convex portion is provided directly on the surface of an outer wall plate, and a tile engageable with the convex portion is hooked and fixed.

  The outer wall structures described in Patent Literature 1 and Patent Literature 2 have disadvantages in that it is necessary to manufacture a separate reinforcing member and a receiving member, which increases the cost, and that it takes time to attach the reinforcing member and the receiving member. is there. In the outer wall structures described in Patent Literature 3 and Patent Literature 4, since the tiles are only hooked directly, the labor required for installation can be reduced. However, for example, when a force is applied to shift the tile and the outer wall in the vertical direction due to an earthquake or the like, there is a problem that the tile moves upward with respect to the outer wall and the tile comes off.

  In view of the problems of the prior art, an object of the present invention is to provide an external member mounting structure that can securely mount an external member, and at the same time, reduce costs and reduce mounting work. I do.

The mounting structure of the exterior member of the present invention is such that an outer wall plate having a surface recess extending in one direction is attached to a building body of a building in a state where the surface recess is oriented in a horizontal direction, and the outer wall plate is provided in the surface recess of the outer wall plate. An attachment structure for an exterior member for attaching an exterior member, wherein a locking means for locking the exterior member in the surface recess, and a first separation preventing means for preventing separation of the exterior member from the surface recess. Wherein the locking means comprises a locking projection formed in the surface recess and protruding upward, and a hooking recess formed on the exterior member and locked to the locking projection, 1 of spaced prevention means, Ri Do from the housing recess formed in an upper portion of said surface recess, and accommodating protrusion is accommodated from below the housing recess formed in an upper portion of the outer member, said locking means In the state locked by The clearance is present between the storage recess and the storage protrusion of the separation prevention means, and the storage protrusion is stored in the storage recess in a state in which the locking by the locking means is released. in which the exterior member is characterized that you have a vertically movable within said surface recess.

  In the mounting structure of the exterior member according to the present invention, the locking means includes a locking projection formed in the surface recess of the outer wall plate and protruding upward, and a hooking recess formed on the exterior member and locked to the locking projection. In addition, there is provided first separation preventing means, which is a storage recess formed at an upper portion in the surface recess of the outer wall plate and a storage protrusion formed at an upper portion of the exterior member and stored in the storage recess from below. That is, the exterior member is not only locked on the outer wall plate, but also the storage protrusion on the upper portion of the exterior member is stored in the storage recess of the surface recess of the outer wall plate. Therefore, it is possible to attach the exterior member only by hooking the exterior member on a predetermined portion of the outer wall plate without requiring any mounting parts. Even if a force acting to shift the exterior member and the outer wall plate in the vertical direction is applied and the exterior member moves upward with respect to the outer wall plate, the first separation preventing means causes the storage recess of the outer wall plate to move into the storage recess of the outer wall plate. Since the storage protrusion of the exterior member is housed, the exterior member can be prevented from coming off. Thus, the exterior member can be securely attached in various use environments, and the cost can be suppressed, and the attachment work can be reduced.

Wherein the exterior member is moved upwardly in said surface recess in a state of releasing the engagement, that provides a second spacing preventing means for preventing the separation of the outer member from the surface recess. The second separation preventing means includes a locking recess formed in the surface recess and opening downward, and the engaging member formed in the exterior member and moving the exterior member upward in the surface recess. ing from the hooking projection for locking the locking recess.

  In this case, in a state in which the exterior member is moved upward in the surface recess of the outer wall plate by the second separation prevention means including the locking concave portion that opens downwardly of the outer wall plate and the hooking projection of the external member, The hooking projection is locked in the locking recess. Thus, the exterior member does not come off simply by moving the exterior member upward in the surface recess of the outer wall plate. Unless the lower part of the exterior member is once separated from the outer wall plate, the exterior member does not come off from the outer wall plate, so that the exterior member can be effectively prevented from falling off.

  An adhesive may be filled between the locking concave portion and the hooking projection in the second separation prevention means. In this case, the attachment of the exterior member can be made stronger.

  A support portion that supports the exterior member from below in a state where the exterior member is locked may be formed in the surface concave portion. Since the locked exterior member is supported by the support portion from below, the force applied to the upwardly projecting locking projection formed in the surface recess of the outer wall plate is dispersed to the support portion, and the locking is performed. The durability of the projection can be improved. Therefore, the exterior member does not come off due to breakage of the locking projection, and the exterior member can be securely attached for a long period of time.

  A third separation preventing unit for preventing separation of the exterior member from the surface recess may be provided. The third separation preventing means includes a lower projection formed at a lower portion in the surface recess and projecting upward, and the lower projection formed at a lower portion of the exterior member and locked with the exterior member. And a lower concave portion fitted from above.

  In this case, the exterior member is engaged by a third separation preventing means including a lower projection formed at a lower portion in the lower surface recess of the outer wall plate and projecting upward and a lower recess formed at a lower portion of the exterior member. In the stopped state, the lower recess is fitted into the lower projection from above. Thus, the lower portion of the exterior member does not separate from the outer wall plate in a state where the exterior member is locked, so that the exterior member can be more effectively prevented from falling off.

  The exposed width of the outer surface of the outer wall plate in the transverse direction of the surface concave portion may be equal to or different from the exposed width of the outer surface of the exterior member. If the outer surface exposed width of the outer wall plate in the transverse direction of the surface concave portion is approximately the same as the outer surface exposed width of the exterior member, a design that has never existed can be obtained, and a building having a very good appearance can be obtained. . If the outer surface width of the outer wall plate in the transverse direction of the surface recess is made different from the outer surface exposure width of the exterior member, a design different from the case where the outer surface width is made equal is obtained, and the building has a very good appearance. It can be. As described above, by adjusting the outer surface exposed width of the outer wall plate and the outer surface exposed width of the exterior member in the transverse direction of the surface concave portion, the outer wall of high design having both the texture of the exterior wall plate and the texture of the exterior member is adjusted. Configuration can be obtained.

  The outer wall plate may be an extruded cement plate in which a plurality of hollow portions are juxtaposed in one direction, and the extruded cement plate may be attached to a building frame in a laterally stretched state.

  According to the present invention, since the hooking concave portion of the exterior member is locked to the locking projection projecting upward from the outer wall plate, no mounting component is required, and the exterior member is merely hooked on a predetermined portion of the outer wall plate. An exterior member can be attached. Even if a force acting to shift the exterior member and the outer wall plate in the vertical direction acts and the exterior member moves upward with respect to the outer wall plate, the storage protrusion of the exterior member is located in the storage recess of the outer wall plate. It can be stored and the exterior member can be prevented from coming off. Thus, the exterior member can be securely attached, the cost can be reduced, and the attachment work can be reduced.

  The outer wall plate 2 has a plurality of surface recesses 3 extending in the longitudinal direction. Therefore, the surface-side substrate of the outer wall plate 2 includes the substrate body 6, the plurality of surface concave portions 3, and the plurality of convex portions 7. The outer wall plate 2 is attached to the building frame with the surface concave portion 3 oriented in the horizontal direction.

  As shown in FIG. 3, the mounting structure 1 for the exterior member of the present embodiment prevents the exterior member 4 from being separated from the surface recess 3 by the locking means 8 for engaging the exterior member 4 in the surface recess 3. And first separation preventing means 9. A rib 10 is formed substantially at the center in the vertical direction in the surface concave portion 3. A locking projection 11 projecting upward is formed at the upper end of the rib 10. On the other hand, a rib recess 12 into which the rib 10 enters is formed on the left side of the exterior member 4. At the upper end in the rib recess 12, a hook recess 13 is formed to be locked to the locking projection 11 of the outer wall plate 2.

  The locking projections 11 formed on the ribs 10 of the outer wall plate 2 and the hooking recesses 13 formed on the upper end of the exterior member 4 constitute locking means 8 for locking the exterior member 4 in the surface recess 3. ing. The outer member 4 is locked to the outer wall plate 2 by the locking means 8, and the locking means 8 is a main attachment portion for mounting the outer member 4 to the outer wall plate 2.

  A storage recess 15 that is recessed upward is formed in the upper part of the surface recess 3 of the outer wall plate 2. On the other hand, on the upper part of the exterior member 4, there is formed a storage protrusion 16 which is formed to project upward and is stored in the storage recess 15 from below. The storage recess 15 formed in the surface recess 3 of the outer wall plate 2 and the storage protrusion 16 formed in the upper part of the exterior member 4 constitute the first separation preventing means 9. In the locked state of the exterior member 4 shown in FIG. 3, only the tip of the storage protrusion 16 of the exterior member 4 is located in the storage recess 15 of the outer wall plate 2, and a gap 17 exists. In the state shown in FIG. 4 in which the exterior member 4 is moved upward in the surface recess 3 and the engagement is released, the storage protrusion 16 is stored in the storage recess 15, and the upper part of the exterior member 4 from the outer wall plate 2. Is prevented from being separated. Therefore, the exterior member 4 does not come off from the outer wall plate 2 just by moving the exterior member 4 upward.

  The exterior member mounting structure 1 further prevents the exterior member 4 from being separated from the surface recess 3 in a state where the exterior member 4 is moved upward in the surface recess 3 and disengaged. Means 19 are provided. At the lower end of the rib 10 of the outer wall plate 2 is formed a locking recess 20 which is depressed upward and opened downward. At the lower end in the recess 12 for the rib of the exterior member 4, a hooking projection 21 which is engaged with the engagement recess 20 of the outer wall plate 2 is formed. The second recess preventing means 19 is constituted by the locking recess 20 formed in the surface recess 3 of the outer wall plate 2 and the hooking protrusion 21 formed in the exterior member 4.

  In the locked state of the exterior member 4 shown in FIG. 3, the hooking projections 21 of the exterior member 4 are not locked in the locking recesses 20 of the outer wall plate 2, and the hooking projections 21 are located between the locking recesses 20 and the hooking projections 21. Has a gap 22. In the state shown in FIG. 4 in which the exterior member 4 is moved upward in the surface concave portion 3 and the engagement is released, the hooking projection 21 is locked by the locking concave portion 20, and the exterior member 4 Separation of the lower part is prevented. Therefore, when the exterior member 4 is simply moved upward by the second separation prevention means 19, the exterior member 4 is not detached from the outer wall plate 2 in combination with the first separation prevention means 9. Unless the lower part of the exterior member 4 is once separated from the outer wall plate 2, the exterior member 4 does not come off from the outer wall plate 2, so that the exterior member 4 can be effectively prevented from falling off.
