Description

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

For example, extruded cement boards are widely used as exterior wall boards of buildings because they are lightweight and have high strength. In an outer wall structure using an extruded cement plate, an angle as a base material is generally fixed to the building frame, and a Z clip or the like fastened to the back surface of the extruded cement plate is locked to the angle for extrusion. A molded cement board is attached.

Exterior members such as stones and tiles are also attached to the surface of extruded cement boards. Various exterior members are attached by directly attaching them to the surface of the extruded cement plate with an adhesive or mortar, or by fastening them to the extruded cement plate with mounting brackets. Patent Document 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 outer wall plate via a reinforcing material provided in the concave portions. Patent Document 2 describes an outer wall structure in which a receiving metal fitting having a hooking portion is fixed to an outer wall plate, and an exterior member is hooked and fixed to the hooking portion of the receiving metal fitting.

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

The outer wall structure described in Patent Document 1 and Patent Document 2 has a drawback that it is necessary to manufacture a separate reinforcing material and receiving metal fitting, which increases the cost and also takes time and effort to attach the reinforcing material and the receiving metal fitting. be. In the outer wall structure described in Patent Document 3 and Patent Document 4, since the tile is only directly hooked, the time and effort for attaching the tile can be reduced. However, for example, when a force that shifts the tile and the outer wall in the vertical direction acts 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.

Therefore, in view of the problems of the prior art, it is an object of the present invention to provide an exterior member mounting structure capable of reliably mounting the exterior member, reducing the cost, and reducing the mounting work. do.

In the mounting structure of the exterior member of the present invention, an outer wall plate having a surface recess extending in one direction is attached to the building frame with the surface recess oriented in the horizontal direction, and the outer wall plate is inside the surface recess. A mounting structure for an exterior member to which the exterior member is attached, wherein the locking means for locking the exterior member in the surface recess and a first separation preventing means for preventing the exterior member from being separated from the surface recess. The locking means comprises a locking projection formed in the surface recess and protruding upward, and a hook recess formed in the exterior member and locked to the locking projection. The separation preventing means of 1 is composed of a storage recess formed in the upper part of the surface recess and a storage protrusion formed in the upper part of the exterior member and stored in the storage recess from below. In the locked state, there is a gap between the storage recess of the first separation preventing means and the storage protrusion, and the storage recess is stored in the storage recess in a state where the locking by the locking means is released. projection that is housed, the outer member is movable in the vertical direction within the surface recess, when attaching the outer member to the outer wall plate, the housing projection by tilting the package member Is inserted into the storage recess, the lower part of the exterior member is brought close to the outer wall plate with the storage protrusion as a fulcrum, the hook recess is locked to the locking projection, and the exterior member is removed from the outer wall plate. Is tilting the exterior member to separate the lower portion from the outer wall plate, moving the tilted exterior member upward to insert the storage protrusion into the storage recess, and then to the locking projection of the hook recess. The storage protrusion, the storage recess, the hook recess, the locking projection, and the storage protrusion, the storage recess, the hook recess, and the storage protrusion so as to be detachable by tilting the exterior member with respect to the outer wall plate by releasing the lock. It is characterized in that the dimension of the gap is set.

In the mounting structure of the exterior member of the present invention, the locking means includes a locking protrusion formed in the surface recess of the outer wall plate and protruding upward, and a hooking recess formed in the exterior member and locked to the locking protrusion. In addition, it has a first separation preventing means such as a storage recess formed in the upper part of the surface recess of the outer wall plate and a storage protrusion formed in the upper part of the exterior member and stored in the storage recess from below. That is, not only the exterior member is locked to the outer wall plate, but also the storage protrusion on the upper part of the exterior member is stored in the storage recess of the surface recess of the outer wall plate. Therefore, the exterior member can be attached by simply hooking the exterior member at a predetermined position on the outer wall plate without requiring an attachment component. Even if a force that shifts 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 first separation preventing means is used to make the storage recess of the outer wall plate. Since the storage protrusion of the exterior member is stored, it is possible to prevent the exterior member from coming off. As a result, the exterior member can be reliably attached in various usage environments, and at the same time, the cost can be suppressed and the attachment work can be reduced.

It is preferable to provide a second separation preventing means for preventing the exterior member from being separated from the surface recess in a state where the exterior member is moved upward in the surface recess to disengage the engagement. The second separation preventing means engages with a locking recess formed in the surface recess that opens downward and a state in which the exterior member is formed in the exterior member and the exterior member is moved upward in the surface recess. It may be composed of a hooking protrusion that locks in the stop recess.

In this case, the exterior member is moved upward in the surface recess of the outer wall plate by the second separation preventing means including the locking recess that opens downward of the outer wall plate and the hooking protrusion portion of the exterior member. The hooking protrusion is locked in the locking recess. As a result, the exterior member does not come off only when the exterior member moves upward in the surface recess of the outer wall plate. Since the exterior member does not come off from the outer wall plate until the lower portion of the exterior member is once separated from the outer wall plate, it is possible to effectively prevent the exterior member from falling off.

A support portion that supports the exterior member from below may be formed in the surface recess in a state where the exterior member is locked. Since the locked exterior member is supported from below by this support portion, 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 locked. The durability of the protrusions can be improved. Therefore, the exterior member does not come off due to the breakage of the locking projection, and the exterior member can be reliably attached for a long period of time.

A third separation preventing means for preventing the exterior member from being separated from the surface recess may be provided. The third separation preventing means includes a lower protrusion formed in the lower part of the surface recess and projecting upward, and the lower protrusion formed in the lower part of the exterior member and locked with the exterior member. It may consist of a lower recess that is fitted from above.

In this case, the exterior member is engaged by a third separation preventing means composed of a lower protrusion formed in the lower portion of the surface recess of the outer wall plate and protruding upward and a lower recess formed in the lower portion of the exterior member. In the stopped state, the lower recess is fitted into the lower protrusion from above. As a result, when the exterior member is locked, the lower portion of the exterior member does not separate from the outer wall plate, so that the exterior member can be prevented from falling off more effectively.

The outer surface exposure width of the outer wall plate in the transverse direction of the surface recess may be equal to or different from the outer surface exposure width of the exterior member. If the exposed width of the outer surface of the outer wall plate in the transverse direction of the surface recess is set to the same level as the exposed width of the outer surface of the exterior member, an unprecedented design can be obtained and the building can have a very good appearance. .. If the exposed width of the outer surface of the outer wall plate in the transverse direction of the surface recess is made different from the exposed width of the outer surface of the exterior member, a design different from the case where the outer wall plate is exposed to the same degree can be obtained, and the building has a very good appearance. Can be. In this way, by adjusting the outer surface exposure width of the outer wall plate and the outer surface exposure width of the exterior member in the transverse direction of the surface recess, the outer wall having both the texture of the outer wall plate and the texture of the exterior member is highly designed. The configuration can be obtained.

The outer wall plate may be an extruded cement plate in which a plurality of hollow portions are arranged side by side in one direction, and the outer wall plate may be attached to the skeleton of a building in a horizontally stretched state.

According to the present invention, since the hooking recess of the exterior member is locked to the locking projection protruding upward of the outer wall plate, no mounting component is required, and the exterior member is simply hooked at a predetermined position on the outer wall plate. , Exterior members can be attached. Even if a force that shifts 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 remains in the storage recess of the outer wall plate. It is stored and can prevent the exterior member from coming off. As a result, the exterior member can be reliably attached, the cost can be suppressed, and the attachment work can be reduced.

The mounting structure 1 of the exterior member is a mounting structure in which the outer wall plate 2 is mounted horizontally on the frame of the building and the exterior member 4 is mounted in the surface recess 3 of the outer wall plate 2. Note that the vertical direction in FIG. 1 is the vertical direction in which the outer wall plate 2 is attached to the building frame. Although there is no concept of up / down / left / right of the outer wall plate 2 and the exterior member 4 in a state of being removed from the building, the upper side in the vertical direction in which the outer wall plate 2 and the exterior member 4 are shown is simply referred to as the upper side in the following description of the structure. , The lower side is simply the lower side, the horizontal left side is simply the left side, and the right side is simply the right side. Further, each portion of the outer wall plate 2 and the exterior member 4 described below all extend in the same shape in the penetrating direction of FIG.

The outer wall plate 2 of the present embodiment is an extruded cement plate formed to have a predetermined length. The outer wall plate 2 is manufactured by extruding a mixture of water, cement, aggregate, fibers and the like with an extrusion molding machine, curing and curing the mixture, and then cutting the outer wall plate 2 to a predetermined size. The outer wall plate 2 is formed with a plurality of hollow portions 5 parallel to each other in the longitudinal direction, which is the extrusion direction. The exterior member 4 of the present embodiment is a tile formed to a predetermined size, and this tile is composed of various materials and is attached to obtain a highly designed appearance of the building.

The outer wall plate 2 is attached to the skeleton of the building by a conventional horizontal construction method. For example, an L-shaped angle extending in the vertical direction is fixed to the frame of the building, and a Z-clip or the like fastened to the extruded cement board is engaged with the L-shaped angle and tightened with mounting bolts to tighten the outer wall plate 2 The end of the is fixed to the L-shaped angle.

The outer wall plate 2 is formed with a plurality of surface recesses 3 extending in the longitudinal direction. Therefore, the surface-side base material of the outer wall plate 2 is composed of a base material main body 6, a plurality of surface recesses 3, and a plurality of convex portions 7. The outer wall plate 2 is attached to the skeleton of the building with the surface recess 3 oriented in the horizontal direction.

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

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

A storage recess 15 that is recessed upward is formed in the upper portion of the outer wall plate 2 in the surface recess 3. On the other hand, on the upper part of the exterior member 4, a storage protrusion 16 is formed so as to project upward and is stored in the storage recess 15 from below. The first separation preventing means 9 is composed of 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. In the locked state shown in FIG. 3 of the exterior member 4, 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 moves upward in the surface recess 3 and is disengaged, the storage protrusion 16 is housed in the storage recess 15, and the upper portion of the exterior member 4 from the outer wall plate 2 Separation is prevented. Therefore, the exterior member 4 does not come off from the outer wall plate 2 only when the exterior member 4 moves upward.

The mounting structure 1 of the exterior member 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 to disengage the engagement. The means 19 is provided. At the lower end of the rib 10 of the outer wall plate 2, a locking recess 20 that is recessed upward and opens downward is formed. At the lower end of the rib recess 12 of the exterior member 4, a hooking protrusion 21 for locking to the locking recess 20 of the outer wall plate 2 is formed. The second separation preventing means 19 is composed of 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 shown in FIG. 3 of the exterior member 4, the hooking protrusion 21 of the exterior member 4 is not locked in the locking recess 20 of the outer wall plate 2, and is between the locking recess 20 and the hooking protrusion 21. There is a gap 22 in. In the state shown in FIG. 4 in which the exterior member 4 moves upward in the surface recess 3 and is disengaged, the hooking protrusion 21 is locked in the locking recess 20 and the exterior member 4 from the outer wall plate 2 is engaged. Separation of the lower part is prevented. Therefore, when the exterior member 4 is moved upward by the second separation preventing means 19, the exterior member 4 does not come off from the outer wall plate 2 in combination with the first separation preventing means 9. Since the exterior member 4 does not come off from the outer wall plate 2 until the lower portion of the exterior member 4 is once separated from the outer wall plate 2, it is possible to effectively prevent the exterior member 4 from falling off.

As shown in FIG. 3, in the state where the exterior member 4 is attached, the exterior member 4 is locked by the locking means 8, and the exterior member 4 is prevented from being separated by the first separation preventing means 9. As shown in FIG. 4, when the exterior member 4 moves upward and is disengaged, the locking means 8 is disengaged, but the first separation preventing means 9 causes the upper portion of the exterior member 4 to be disengaged. Enters the upper part of the outer wall plate 2 in the surface recess 3, and at the same time, the back surface side of the exterior member 4 is locked in the surface recess 3 of the outer wall plate 2 by the second separation preventing means 19.

Therefore, when a force that shifts the exterior member 4 and the outer wall plate 2 in the vertical direction acts, the exterior member 4 moves upward with respect to the outer wall plate 2 to reliably prevent the exterior member 4 from coming off. can. When attaching the exterior member 4 to the outer wall plate 2, the exterior member 4 is tilted and the upper storage protrusion 16 is inserted into the upper storage recess 15 in the surface recess 3 of the outer wall plate 2, and the storage protrusion of the exterior member 4 is inserted. With 16 as a fulcrum, the lower part of the exterior member 4 is brought close to the outer wall plate 2, and the hook recess 13 of the exterior member 4 is locked to the locking projection 11 of the outer wall plate 2. When the exterior member 4 is removed from the outer wall plate 2, the operation is opposite to that at the time of attachment. The exterior member 4 is tilted to separate the lower portion from the outer wall plate 2, the tilted exterior member 4 is moved upward, and the storage protrusion 16 of the exterior member 4 is inserted into the storage recess 15 of the outer wall plate 2. The hooking recess 13 is released from the locking projection 11, and the exterior member 4 is removed from the outer wall plate 2.

The outer surface exposed width L1 of the outer wall plate 2 in the transverse direction of the surface recess 3 of the outer wall plate 2 is about the same as the outer surface exposed width L2 of the exterior member 4. If the outer surface exposed width L1 of the outer wall plate 2 is set to be about the same as the outer surface exposed width L2 of the exterior member 4, a design that has never existed in the past can be obtained, and a building having a very good appearance can be obtained.

The outer surface exposed width L1 of the outer wall plate 2 and the outer surface exposed width L2 of the exterior member 4 can be arbitrarily changed within a range in which the locking means 8 of the exterior member 4 can be formed. The outer surface exposed width L1 of the outer wall plate 2 and the outer surface exposed width L2 of the exterior member 4 may be appropriately set according to the design of the building. For example, the outer surface exposed width L1 of the outer wall plate 2 may be different from the outer surface exposed width L2 of the exterior member 4. In this case, a building having a very good appearance can be obtained by obtaining a design property different from that in the case of making the same degree.

In this way, by adjusting the outer surface exposed width L1 of the outer wall plate 2 and the outer surface exposed width L2 of the exterior member 4 with each other, the outer wall having both the texture of the outer wall plate 2 and the texture of the exterior member 4 is highly designed. The configuration is obtained. In the present embodiment, the extruded cement plate is used as the outer wall plate 2 and the tile is used as the exterior member 4, so that the texture of the extruded cement plate constituting the convex portion 7 and the texture of the tile which is the exterior member 4 are up and down. The building can have a highly designed appearance that is evenly repeated in the direction.

It has a first separation preventing means 9 such as 16. That is, not only the exterior member 4 is locked to the outer wall plate 2, but also the storage protrusion 16 at the upper part of the exterior member 4 is stored in the storage recess 15 in the surface recess 3 of the outer wall plate 2.

Therefore, the exterior member 4 can be reliably attached by simply hooking the exterior member 4 at a predetermined position on the outer wall plate 2 without requiring an attachment component. Even if a force that shifts the exterior member 4 and the outer wall plate 2 in the vertical direction acts and the exterior member 4 moves upward with respect to the outer wall plate 2, the outer wall is provided by the first separation preventing means 9. Since the storage protrusion 16 of the exterior member 4 is stored in the storage recess 15 of the plate 2, it is possible to prevent the exterior member 4 from coming off. As a result, the exterior member 4 can be reliably attached in various usage environments, and at the same time, the cost can be suppressed and the attachment work can be reduced.

The exterior member 4 is moved upward in the surface recess 3 of the outer wall plate 2 by the second separation preventing means 19 including the locking recess 20 that opens downward of the outer wall plate 2 and the hooking protrusion 21 of the exterior member 4. In this state, the hooking protrusion 21 is locked in the locking recess 20. As a result, the exterior member 4 does not come off only when the exterior member 4 moves upward in the surface recess 3 of the outer wall plate 2. Since the exterior member 4 does not come off from the outer wall plate 2 until the lower portion of the exterior member 4 is once separated from the outer wall plate 2, it is possible to effectively prevent the exterior member 4 from falling off.

FIG. 5 is a cross-sectional view showing a mounting structure 25 of an exterior member according to a second embodiment of the present invention. In the present embodiment, a support portion 26 for supporting the exterior member 4 from below is formed in the surface recess 3 of the outer wall plate 2. In this embodiment, the same reference numerals are given to the configurations common to those in the first embodiment. As shown in FIG. 5, the lower portion of the outer wall plate 2 in the surface recess 3 is formed higher than the lower portion of the outer wall plate 2 of the first embodiment to form the support portion 26. With the exterior member 4 attached to the outer wall plate 2, the lower portion of the exterior member 4 is supported from below by the support portion 26 of the outer wall plate 2. Since the exterior member 4 in the locked state is supported from below by the support portion 26, the force applied to the locking projection 11 formed in the surface recess 3 of the outer wall plate 2 is dispersed to the support portion 26. The durability of the locking projection 11 can be improved. As a result, the exterior member 4 is prevented from falling off due to the breakage of the locking projection 11, and the exterior member 4 can be securely attached for a long period of time.

FIG. 6 is a cross-sectional view showing a mounting structure 28 of an exterior member according to a third embodiment of the present invention. The mounting structure 28 for the exterior member of the present embodiment includes a third separation preventing means 29 for preventing the exterior member 4 from being separated from the surface recess 3.
